Abstract
Abstract An instrument for surgical transection, specimen-taking and endsealing of vessels, nerves and the like (as in vagotomy) having; (1) a clip-setting head to clamp spaced areas of a nerve or vessel and to apply and set hemostatic clips for sealing off those areas, having; (2) a shear for transecting the length of nerve or vessel between the sealed areas, and having; (3) a pocket to receive and hold the transected part for subsequent use as a biopsy specimen.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
207 words
In a surgical instrument for transecting a specimen from an elongated tissue element, in combination: a support; an anvil, carried by said support, said anvil including a shear die, including clip-positioning means at respective sides thereof; a punch mounted on said support for longitudinal sliding movement in axially opposed relation to said die, said punch having a leading end receivable in said die with a shearing action; a plunger, slidably mounted on said support, said plunger having laterally spaced slip-closing jaws provided with clippositioning means in axially opposed relation to said first mentioned clip-positioning means; said instrument having a mouth extending transversely between the pairs of opposed clip-positioning means, and between said anvil and the leading end of the punch when in a normal retracted position, said mouth having a tissue element receiving means extending transversely therein, and receiving a pair of open clips held by said clip-positioning means; means for advancing said punch against a section of said tissue element between said clips, to transect said section by shearing action against said die; said die having a cavity providing a specimen-holding pocket; and said punch being positioned to move said tissue section into said die cavity after transecting it, for retention as a specimen for examination.
Claim 2
Dependent Claim
207 words
In a surgical instrument for transecting a specimen from an elongated tissue element, in combination: a support; an anvil, carried by said support, said anvil including a shear die, including clip-positioning means at respective sides thereof; a punch mounted on said support for longitudinal sliding movement in axially opposed relation to said die, said punch having a leading end receivable in said die with a shearing action; a plunger, slidably mounted on said support, said plunger having laterally spaced slip-closing jaws provided with clippositioning means in axially opposed relation to said first mentioned clip-positioning means; said instrument having a mouth extending transversely between the pairs of opposed clip-positioning means, and between said anvil and the leading end of the punch when in a normal retracted position, said mouth having a tissue element receiving means extending transversely therein, and receiving a pair of open clips held by said clip-positioning means; means for advancing said punch against a section of said tissue element between said clips, to transect said section by shearing action against said die; said die having a cavity providing a specimen-holding pocket; and said punch being positioned to move said tissue section into said die cavity after transecting it, for retention as a specimen for examination.
Claim 3
Dependent Claim
34 words
A transecting instrument as defined in claim 1, wherein, said plunger-advancing means comprises a spring, interposed between said punch and said plunger, and yieldingly transmitting a portion of the punch movement to the plunger.
Claim 4
Dependent Claim
42 words
A transecting instrument as defined in claim 2, including a slide bearing integral with said support, in which said punch is slidable, the forward end of said slide bearing being axially spaced from said anvil to define a portion of said mouth.
Claim 5
Dependent Claim
51 words
A transecting instrument as defined in claim 3, wherein, said slide bearing is of rectangular section having parallel flat sides, and wherein, said plunger is of rectangular inverted channel section with side members embracing said flat sides of the bearing, and with said jaws being forward extremities of said slide members.
Claim 6
Dependent Claim
67 words
A transecting instrument as defined in claim 4, including a spring abutment nut, adjustably mounted on the rear end of said punch and a washer abutting the rear end of said plunger, slidable on said punch, and transmitting the load of said spring to said plunger; said spring being a coil spring encircling said punch, with its ends engaged under compression against said washer and abutment nut.
Claim 7
Dependent Claim
25 words
A transecting instrument as defined in claim 1, wherein, said support has a rear end provided with means for detachable anchorage to a pressure-applying forceps.
Claim 8
Dependent Claim
24 words
A transecting instrument as defined in claim 1, including separate lever devices for independently transmitting respective movements to said plunger and to said punch.
