Abstract

A lamb castration clamp (100) comprising: a pair of jaws (102), each jaw comprising an inner contact surface (110) and an outer engagement formation (112) for force to be applied to the jaws; hinge apparatus (106) connecting proximal ends of the jaws such that the jaws are movable from an open position, in which the jaws are spaced apart to receive the neck of the scrotum of a lamb, to a closed position, in which the jaws are close together so that the contact surfaces crushingly clamp the spermatic cords and nerves in the neck of the scrotum so as to stop conduction of the nerves and blood flow to the scrotum; and a retaining element (108) for retaining the jaws in the closed position.

Claims (16)

1 . A lamb castration clamp comprising: a pair of jaws, each jaw comprising an inner contact surface and an outer engagement formation for force to be applied to the jaws; hinge apparatus connecting proximal ends of the jaws such that the jaws are movable from an open position, in which the jaws are spaced apart to receive the neck of the scrotum of a lamb, to a closed position, in which the jaws are close together so that the contact surfaces crushingly clamp the spermatic cords and nerves in the neck of the scrotum so as to stop blood flow to the scrotum and conduction by the nerves; and a retaining element configured to retain the jaws in the closed position.
2. A lamb castration clamp as claimed in claim 1 , wherein the contact surfaces are sized and shaped to convert a force applied to the jaws into a pressure of 7-16 MPa to be applied to the neck of the scrotum, so that the contact surfaces crushingly clamp the spermatic cords and the nerves in the neck of the scrotum so as to stop blood flow to the scrotum and conduction by the nerves.
3. A lamb castration clamp as claimed in claim 1 or claim 2, wherein the contact surfaces are sized and shaped to convert up to 100kg applied force into a pressure of 7-16 MPa to be applied to the neck of the scrotum.
4. A lamb castration clamp as claimed in any preceding claim, wherein the contact surfaces have a length of 50-70 mm and a width of 0.2-2 mm.
5. A lamb castration clamp as claimed in any preceding claim, wherein the hinge apparatus comprises a flexure hinge.
6. A lamb castration clamp as claimed in claim 5, wherein the retaining element comprises a latch flexibly mounted at the distal end of one of the jaws.
7. A lamb castration clamp as claimed in any of claims 1 to 4, wherein the hinge apparatus comprises a hinge barrel mounted in hinge socket and an elastically deformable retaining element configured to generally retain the hinge barrel within the hinge socket, while allowing some movement of the hinge barrel within the hinge socket.
8. A lamb castration clamp as claimed in any of claims 1 to 5 or claim 7, wherein the retaining element and/or the elastically deformable retaining element comprises at least one elastically deformable ring.
9. A lamb castration clamp as claimed in any preceding claim, wherein the first and second contact surfaces have complementary shaped longitudinal profiles.
10. A lamb castration clamp as claimed in claim 9, wherein the first and second contact surfaces have generally smooth or toothed longitudinal profiles.
1 1 . A lamb castration clamp as claimed in claim 9 or claim 10, wherein the first and second contact surfaces have straight or curved longitudinal profiles.
12. A lamb castration clamp as claimed in any preceding claim, further comprising a pair of guide arms provided on one jaw such that the inner contact surface of said jaw is located generally between the guide arms, the guide arms are configured to align the inner contact surfaces of the jaws in the closed position and to help gather and retain the tissues of the neck of the scrotum.
13. A lamb castration clamp as claimed in any preceding claim, wherein at least the jaws are formed from a biodegradable material.
14. Lamb castration apparatus comprising: clamping pliers comprising plier jaws and operating handles, the plier jaws being movable between an open position and a closed position by the operating handles; and a lamb castration clamp as claimed in any of claims 1 to 13, wherein the engagement formations of the lamb castration clamp are engageable by the plier jaws such that the jaws of the lamb castration clamp are moveable from the open position to the closed position by the plier jaws moving from the open position to the closed position.
15. Lamb castration apparatus as claimed in claim 14, wherein the clamping pliers are configured to apply 80-100kg force to the castration clamp.
16. Lamb castration apparatus as claimed in claim 14 or claim 15, wherein the clamping jaws comprise engagement formations at their distal ends, the engagement formations configured to engage the engagement formations of the lamb castration clamp.
