Abstract

Abstract A veterinarian's tool for castrating animals with which all of the castrating operations can be performed with a single tool held in one hand of the operator, the tool operating to sever the spermatic cord by searing or cauterization and comprising a pair of arms pivotally connected together to operate in scissor-like manner, one arm having a cutting blade at its upper end for making an opening in an animal's scrotum, the other arm having a "V" or fork at its upper end for stripping back the covering of the spermatic cord after it has been pulled out of the animal's body, and a heating element on one of the arms, the arms cooperating upon closing to hold the animal's spermatic cord against the heating element until the cord is severed by searing or cauterization.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 117 words
A tool for castrating animals operating to sever the spermatic cord at least partly by searing or cauterization, comprising: (a) a pair of arms pivotally connected together to operate in scissor-like manner; (b) means on one of said arms for stripping the covering of the spermatic cord of an animal after the cord has been pulled out of the animal's body during castration, (c) a heating area on one of said arms cooperating with said other arm upon closing of the arms to contact the spermatic cord of an animal between said arms to sever the cord at least partly by searing or cauterization, and (d) means for connecting said heating area to a source of energy.
Claim 2
Dependent Claim 117 words
A tool for castrating animals operating to sever the spermatic cord at least partly by searing or cauterization, comprising: (a) a pair of arms pivotally connected together to operate in scissor-like manner; (b) means on one of said arms for stripping the covering of the spermatic cord of an animal after the cord has been pulled out of the animal's body during castration, (c) a heating area on one of said arms cooperating with said other arm upon closing of the arms to contact the spermatic cord of an animal between said arms to sever the cord at least partly by searing or cauterization, and (d) means for connecting said heating area to a source of energy.
Claim 3
Dependent Claim 25 words
The tool of claim 1 in which said means for stripping is a "V" or fork at the end of said one of said arms.
Claim 4
Dependent Claim 24 words
The tool of claim 1 including a cutting surface on one of said arms for cutting an opening in the scrotum of an animal.
Claim 5
Dependent Claim 13 words
The tool of claim 3 in which said cutting surface is a blade.
Claim 6
Dependent Claim 11 words
The tool of claim 4 in which said blade is removable.
Claim 7
Dependent Claim 179 words
A tool for castrating animals by which the spermatic cords are severed by searing or cauterizing comprised of: (a) a pair of arms pivotally connected together at a pivot point to operate in scissor-like manner resulting in a pair of arm sections on each side of said pivot point, one pair of arm sections having distal ends distal to said pivot point adapted to support a cutting blade or a fork;. (b) a cutting blade at said distal end of one of said arm sections for making an opening in the scrotum of an animal; (c) a "V" or fork on said distal end of said other arm section for stripping the covering of the spermatic cord of an animal after the cord has been pulled out of the animal's body, (d) a heating element on one of said arms cooperating with said other arm upon closing of the arms to contact the spermatic cord of an animal to sever the cord by searing or cauterization, and (e) means for connecting said heating element to a source of energy.
Claim 8
Dependent Claim 179 words
A tool for castrating animals by which the spermatic cords are severed by searing or cauterizing comprised of: (a) a pair of arms pivotally connected together at a pivot point to operate in scissor-like manner resulting in a pair of arm sections on each side of said pivot point, one pair of arm sections having distal ends distal to said pivot point adapted to support a cutting blade or a fork;. (b) a cutting blade at said distal end of one of said arm sections for making an opening in the scrotum of an animal; (c) a "V" or fork on said distal end of said other arm section for stripping the covering of the spermatic cord of an animal after the cord has been pulled out of the animal's body, (d) a heating element on one of said arms cooperating with said other arm upon closing of the arms to contact the spermatic cord of an animal to sever the cord by searing or cauterization, and (e) means for connecting said heating element to a source of energy.
Claim 9
Dependent Claim 173 words
In a castrating tool comprising a pair of arms pivotally connected together at a pivot point to open and close in scissor-like manner resulting in a pair of arm sections on each side of said pivot point, one pair of arm sections having distal ends distal to said pivot point adapted to support a cutting blade or a fork, one of said arm sections having a cutting blade at its distal end for making an opening in the scrotum of an animal, the improvement which comprises a heating element on one of said arms cooperating with the other of said arms upon closing of the arms to contact the spermatic cord of an animal during castration to sever the cord by searing or cauterization, means for connecting said heating element to a source of energy, and a "V" or fork at said distal end of the other of said arms for stripping the covering of the spermatic cord of an animal after the cord has been pulled from the animal's body during castration.
Claim 10
Dependent Claim 173 words
In a castrating tool comprising a pair of arms pivotally connected together at a pivot point to open and close in scissor-like manner resulting in a pair of arm sections on each side of said pivot point, one pair of arm sections having distal ends distal to said pivot point adapted to support a cutting blade or a fork, one of said arm sections having a cutting blade at its distal end for making an opening in the scrotum of an animal, the improvement which comprises a heating element on one of said arms cooperating with the other of said arms upon closing of the arms to contact the spermatic cord of an animal during castration to sever the cord by searing or cauterization, means for connecting said heating element to a source of energy, and a "V" or fork at said distal end of the other of said arms for stripping the covering of the spermatic cord of an animal after the cord has been pulled from the animal's body during castration.
