Abstract
Abstract A jaw assembly of an endoscopic biotome is formed by cutting a hemispherical end of a spring metal cylinder with electrical discharge or laser machining equipment to provide opposed jaw cups. Metal is cut from the middle portion of the cylinder to form two tapered arms which terminate at a cylindrical portion of the open end of the cylinder. At least one of the two tapered arms is bent away from the other to form the jaw assembly.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
155 words
A method for forming a jaw assembly for an endoscopic bioptome, comprising: a) obtaining a cylinder of spring metal having a substantially hemispherical end, a middle portion and an open second end; b) cutting said substantially hemispherical end with electrical discharge machining equipment or laser machining equipment to provide opposed jaw cups; c) cutting out metal from said middle portion of said cylinder with electrical discharge machining equipment or laser machining equipment to form two tapered arms which taper from a larger circumference at said opposed jaw cups to a smaller circumference away from said opposed jaw cups, at least one of said two tapered arms having a portion which extends less than 80 degrees around a periphery of said cylinder, said two tapered arms terminating at a cylindrical portion of said open second end; and d) bending at least one of said two tapered arms away from the other of said two tapered arms.
Claim 2
Independent Claim
155 words
A method for forming a jaw assembly for an endoscopic bioptome, comprising: a) obtaining a cylinder of spring metal having a substantially hemispherical end, a middle portion and an open second end; b) cutting said substantially hemispherical end with electrical discharge machining equipment or laser machining equipment to provide opposed jaw cups; c) cutting out metal from said middle portion of said cylinder with electrical discharge machining equipment or laser machining equipment to form two tapered arms which taper from a larger circumference at said opposed jaw cups to a smaller circumference away from said opposed jaw cups, at least one of said two tapered arms having a portion which extends less than 80 degrees around a periphery of said cylinder, said two tapered arms terminating at a cylindrical portion of said open second end; and d) bending at least one of said two tapered arms away from the other of said two tapered arms.
Claim 3
Dependent Claim
24 words
A method according to claim 1, wherein: said step of cutting said substantially hemispherical end includes forming reciprocal teeth in said opposed jaw cups.
Claim 4
Dependent Claim
56 words
A method according to claim 1, wherein: said step of cutting said substantially hemispherical end comprises causing one of said jaw cups to be larger than the other, and said method further comprises cutting said larger of said jaw cups to provide a pair of proximally extending wings, and bending said proximally extending wings radially inwardly.
Claim 5
Dependent Claim
42 words
A method according to claim 3, wherein: an upper edge of the larger of said jaw cups proximal of said hemispherical end is bent radially inward so that it enters the smaller of said jaw cups when said jaws cups are closed.
