Abstract

Abstract A clamp and method for castrating livestock is provided. The clamp includes a pair of opposed elongated members, each having a curved jaw and a handle. The members are pivotally coupled so that the clamp may be selectively moved from an open position, wherein the jaws are maintained in close spatial proximity. The clamp also includes a locking mechanism whereby the clamp can be selectively locked in the closed position. At least one handle of a member is adapted to be engaged with the chuck of a power rotary device. The method includes first making an incision in the scrotum. The testes are pulled away from the scrotum and the scrotum is pushed upwardly to allow unobstructed access to the spermatic cords. The jaws of the device are then positioned over one spermatic cord and locked in the closed position. The rotary device is then activated thereby rotating the clamp and causing the spermatic cord to twist sad break. The process is then repeated with respect to the second testis.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 94 words
A method for castrating livestock using a locking clamp having curved jaws and a pair of handles, said method comprising: incising the scrotum and removing the testis to expose the spermatic cord; applying said jaws of said clamp over the exposed spermatic cord; rotating the clamp with the cord secured between the jaws by mechanical rotative force applied to the clamp from a source of torque coupled with one of said handles; and continuing to twist the cord by said rotating of the clamp until the cord breaks as a result of said twisting.
Claim 2
Independent Claim 94 words
A method for castrating livestock using a locking clamp having curved jaws and a pair of handles, said method comprising: incising the scrotum and removing the testis to expose the spermatic cord; applying said jaws of said clamp over the exposed spermatic cord; rotating the clamp with the cord secured between the jaws by mechanical rotative force applied to the clamp from a source of torque coupled with one of said handles; and continuing to twist the cord by said rotating of the clamp until the cord breaks as a result of said twisting.
Claim 3
Dependent Claim 39 words
The method of claim 1 wherein said clamp is applied to said cord in a manner so that the cord may be rotated generally longitudinally of the rotation of the clamp, thereby twisting the cord along its longitudinal axis.
Claim 4
Dependent Claim 35 words
The method of claim 2 wherein said jaws of the clamp are applied to said cord to exert holding force, whereby the cord is securely maintained within the jaws but not severed by the same.
Claim 5
Dependent Claim 34 words
The method of claim 3 wherein the clamp is locked in position to maintain holding force exerted by the jaws on the cord to prevent slippage of the cord from the jaws during rotation.
Claim 6
Dependent Claim 45 words
The method of claim 4 wherein said rotation of the clamp with the cord secured therein causes the cord to break, thereby creating a knot-like formation at the point of breakage on the cord to prevent excessive bleeding and reduce the likelihood of subsequent infection.
Claim 7
Dependent Claim 16 words
The method of claim 5 wherein the clamp is releasably engaged to said source of torque.
Claim 8
Dependent Claim 51 words
The method of claim 6 wherein the clamp is releasably engaged to said source of torque in a manner so that the clamp rotates about an axis projecting through the jaws so that the cord secured within the jaws twists about the approximate axis of rotation of the mechanical rotative force.
Claim 9
Dependent Claim 14 words
The method of claim 7 wherein said source of torque is an electric motor.
Claim 10
Dependent Claim 14 words
The method of claim 8 wherein said electric motor is a cordless, electric drill.
Claim 11
Dependent Claim 28 words
The method of claim 9 wherein the scrotum is incised from a point above the testes through the ventral extremity of the scrotum to allow proper fluid drainage.
