In caponizing operations it is usual to employ several instruments used in succession to carry out and complete the operation. In the first place, a scalpel is used held at the correct angle for mak ing the preliminary incision. When this has been done, it is necessary to insert, in the incision, a spreading instrument and to unclasp it so that its arms will spread apart, thus to hold the edges of 10 the incision apart so that the operator may then use the forceps to complete the operation. These several steps require time and, when it is con sidered that following the completion of the op eration the spreading instrument must be re moved, it will be obvious that if some 01' these steps 2 operating gripping portions for gripping parts of This invention relates to caponizing instru jaws being tapered rearwardly of its gripping por tion to fonn a gradually widening spreader por tion capable of spreading the incision in the bird and retaining the edges of the incision spread apart while employing the gripping portions with in the incision. The upper Jaw is preferably formed with a longitudinal recess to provide a viewing opening during the operation while this upper Jaw is also preferably of channelled forma tion having side ?anges forming the spreading portions of the instrument as the upper Jaw ta pers outwardly and widens rearwardly of the grip 15 ping portions. Preferably also the instrument in could be feasibly eliminated that considerable time could be saved, which would mean the ca ponizing of a greater number of birds than ordi narily possible. cludes a scalpel blade connected intermediate the ends of the element and projecting therefrom at an angle thereto. The invention will be clearly understood by reference to the following detailed speci?cation taken in conjunction with the accompanying We have found that these several steps can be drawing. taken care of by one instrument, which in actual In the drawing use has provided for the caponizing of a much Figure 1 is a perspective view of the improved greater number of birds than could have been dealt with under ordinary methods by the same 25 type of caponizing instrument according to the operator.

It is therefore an object of the present inven tion to provide a simple caponizing instrument in the form of an improved type of forceps which Figure 2 is a top plan view of this instrument.

While under the present invention the in strument may be made in any practical way so as which will provide for a clear view of the gripping extracting operation. to incorporate the particularly novel construction, portions of the Jaw when within the incision, thus I have illustrated in the accompanying drawing a permitting the operator efficiently to grip those preferred manner of construction wherein the ele parts to be extracted from the bird. With these and other objects in view, the in 50 ments are formed from plate material cut to shape and twisted as at l1. so as to dispose the plate vention generally comprises an improved type of like jaws at right angles to the normal plane of forceps including a pair of elements pivotally con the shank portions [8 of the instrument. nected together intermediate their ends and As shown particularly in Figure 3, the lower jaw formed with handle portions at one end and grip ping jaws at the other end, the Jaws having co 65 It takes the form of a plate-like element having a 2,406,647 3 transverse opening l9 adjacent to its outer end. This forms a gripping portion by providing the narrow bar-like end ‘20. The upper jaw I6 is formed with a similar gripping portion to provide the narrow bar-like end 2|, but preferably the upper jaw is provided with a longitudinally ex tending recess 22 which starts at the bar-like end 2| and extends rearwardly in the upper Jaw throughout a major portion of its extent. This provides a viewing opening through which the op erator can obtain a clear view of internal parts of the bird when the instrument is disposed within the incision as will appear hereinafter. According to a particular feature of the in vention, the jaws are tapered re'arwardly of their gripping portions and gradually widen to form a spreader portion B. In the present illustration. both the upper and lower jaws are tapered in this The scalpel blade C is preferably mounted by slotting the upper end of the blade, as at 26, and causing the slotted portion to straddle the bolt 24, thus the blade C is securely fastened on the shank of the instrument and, by loosening the securing nut of bolt 24, the blade may be pro Jected axially the desired degree. and likewise may be adjusted angularly to the correct position which appears to be required by the operator for performing the cutting operation quickly and efficiently. As shown in Figure 6, the gripping portions of the Jaws are so formed that when they are brought together they will abut one another in parallel relation and the opening It will find its counterpart in the outer end of the recess 22 of the upper jaw l6, Moreover, the ends of the gripping portions are inwardly tapered, as at 21, and 28, respectively, so that the bar-like gripping manner, but it will be appreciated that at least one of these jaws, preferably the upper law, 20 ends 20 and 2! in fact taper down to a relatively narrow edge at the point where they engage one should be so tapered. In the preferred form of another when. the Jaws are closed. On the one construction the upper jaw is of channel forma hand the tapered portions 21 and 28 serve to push tion, being provided with the side ?anges 23 pro internal parts of the bird away from the testis jecting upwardly from the plane of the jaw and as the gripping portions of the jaws envelope the . being outwardly curved and ?ared. This forms latter. On the other hand, the tapered portions a practical spreading portion which, when the 21 and 23 serve to provide a very narrow gripping jaws are projected through an incision in the bird, will hold the side edges of the incision spread apart and permit the operator to see the ‘necessary interior parts of the bird as the operation is being performed. A particularly clear view is‘provided by a combination of both the spreader portion of the jaws and the viewing opening 22 previously referred to. The elements it] and II are preferably pivoted together by means of a. bolt 2-‘: which is provided with an enlarged shoulder bearing portion 25 (see Figure 5), which is designed to pass through a receiving orifice in one shank of the instrument while the shank (pivot pin l2) of the bolt 24 passes through the other shank of the instrument. This permits a swinging movement of the ele edge which will lend to the practical and elli cient gripping of the tissue so as to provide for the ?nal parting of the tissues properly. In operation the caponlzing instrument is grasped in normal manner by the handle por tions and assuming that the bird has been pre pared for the operation the skin of the bird is stretched tightly by the thumb and index ?nger of the left hand in that area overlying the last and second last ribs of the bird. The instrument is‘then disposed so that the point of the scalpel blade C is substantially at right angles to the plane of the skin at this point. The skinis-then laid open in normal manner by a stroke of the scalpel and, in fact, an experienced operator using ments of the instrument one to the other'with this instrument may also penetrate the under out loosening the bolt connection. Preferably the instrument includes a scalpel blade C which rigidly projects from the shank portions of the instrument and is preferably con nected at their point of pivotal connection. ‘This scalpel blade is designed to project from the shank When the incision has been made the instru ment is then turned slightly on its side so that at a suitable angle, such that when the instru 60 ment is held in a substantially normal position relative to the body of the bird the scalpel blade will be poised at substantially the correct angle to the bird‘s body and corresponding to the posi tion in which the conventional scalpel is held for the operation. Consequently, instead of it being lying tissue, as well as the air sac wall so that in one stroke the organs may be exposed. the gripping portions 26 and 2i of the closed jaws i5 and i6 may be caused to enter the incision. the plate-like portions of the Jaws being substan tially parallel to the edges of the incision, where upon by turning the instrument back again so that the plate-like portions of the laws are dis posed at right angles to the line of the incision. the edges of the incision will be caused to spread apart. and as the instrument is projected through the incision the spreader portions 23 of the in necessary, as in the case of past practice, to hold strument will spread the edges of the incision a scalpel vertically between the thumb and first farther apart as required for proper vision. With and second ?ngers, then performing the opera tion, putting down the scalpel, picking up the 60 the organs exposed through the open incision the Jaws of the instrument are opened and through spreaders, inserting them in the incision, and then the viewing opening 22 of the upper Jaw Hi the operator is enabled readily to locate the testis which is then grasped by the gripping jaws and caused to be received in the recessed portion iii of the lower Jaw and the recess rearwardly of the gripping portion 2| of the upper jaw iii. The jaws with the enclosed testis are now gently with mal operating position, the scalpel blade will be drawn through the incision preferably with a poised above the bird in correct operating posi tion. Therefore, the incision may be made, the 70 slight twisting motion until the various tissues connecting the organ to the body are parted. The forceps inserted therein so as to spread the edges formation of the gripping portions 20 and 2| of the incision and the operation carried out wherein the taper 21 and 28 forms a line edge immediately with the one instrument. The where these portions meet one another permits particular facility of this will be apparent here the operator to completely withdraw the testicle inafter. picking up the forceps to introduce them to the incision, all that is necessary to do is to pick up the forceps and when they are disposed in a posi tion but slightly different from normal position when used in the incision, and therefore disposed in a position substantially coinciding with nor 2,406,647 6 place two sizes of instruments used at the present including the capsule or sac of peritoneal mem brane surrounding it, the epididimus and a short time. piece of the vas deferens or cord. This will there fore avoid a high percentage of slips which other wise occur if all these parts are not removed. the use of the instrument on birds of various sizes Moreover, the viewing opening 22 in the upper jaw i6 materially assists the operator in so en gaging the jaws with these parts that there is One further important point in connection with should be noted in respect to the instrument of the present invention. This is that by incorpo rating a spreader portion gradually widening rearwardly oi the gripping portions of the jaw, it makes it possible to pass the instrument small possibility of leaving any of them in. When this operation has been performed the 10 through the incision to a greater or lesser de bird is preferably reversed and a similar opera tion performed from the other side in the usual manner. gree, as required by the size of the bird. For in stance, in the case of a small bird, the caponizing instrument would ordinarily be passed through It is clear from the foregoing that by the use the opening to a lesser degree than in the case Of this one instrument a great deal of time is of’ a larger bird. correspondingly, therefore, as the instrument of the present invention is pro jected through the incision to a greater or lesser saved in caponizing. It is obvious that the time taken to pick up a scalpel, position it in the cor rect position, make the incision and then put down the scalpel, pick up the spreader and insert the spreaders is avoided, as well as the then nec essarv step of picking up the forceps and pro ceeding with the operation and the final removal of the sprcaders. This series of steps through the use of the present instrument is completely eliminated as it is only necessary to pick up one degree, the spreader portion will spread the in cision correspondingly to a greater or lesser de gree as required in proportion to the extent to which the jaws are projected through the inci sion. Thus, in the case of a larger bird, the in cision will be spread apart to a greater degree as would necessarily be required, while the converse is the case when operating upon a smaller bird. This is compared with the necessity in the case instrument. Then with the instrument disposed of the conventional caponizing instrument of in a position substantially coinciding with that using different sizes of instruments as well as normally used for the extracting operation, the different sizes of spreader. ‘Therefore, if the scalpel blade C is poised in correct position and instrument of the present invention replaces at it only requires a stroke of the scalpel the intro least two different sizes of caponizing forceps, duction of the gripping portions of the jaws to it will be realized that it replaces in effect four the incision and a slight twist, or the instrument complete instruments namely, two sizes of vfor to spread the incision whereupon the operation ceps and two sizes of spreaders. is immediately performed so that the instrument It is apparent that the invention is of such provides an efficient and practical means of per 85 character that it can be readily manufactured forming the operation in much less time. without difficulty. Apart from these important advantages, as What we claim as our invention is: above outlined, it should be noted that due to l. A caponizing instrument comprising a pair the fact that the instrument of the present in vention can be produced along precision lines, 40 of elements pivotaliy connected together inter mediate their ends and formed with handle por as compared with the usual caponizing instru tlons at one end and jaws at the opposite ends. ment at present generally in use, the instrument said jaws being provided with cooperating grip of the present invention can be constructed to ping portions for gripping parts of a bird on which operate on birds of various ages. as compared to two or more instruments of different sizes that 4 a an operation is being performed, the upper jaw being tapered and channelled rearwardly of its are now employed according to the size and age gripping portion to form a gradually widening of the bird. spreader portion and raised side flanges capable In the most usual form of instrument at pres of spreading an incision in the bird and retaining ent in use, the jaws are formed from a single shank usually bent at the end to form a straight (ll v the edges of said incision spread apart while em transverse gripping jaw which. due to the bend ing operation, terminates at each end in arcuate portions joining with inclined shanks that con verge with one another at their point of con ploying the gripping portions within the incision. 2.
