Abstract
Abstract A surgical instrument comprises a support body with an open longitudinal channel, in which are respectively superposed the rod of a pusher member and the rod of a staple housing. A replaceable magazine with staples is secured to a head of the staple housing and drives are provided for moving the staple housing and pusher conjointly to clamp the tissue between the magazine and a jaw on the support body and for thereafter displacing the pusher relative to the staple housing to force staples from the magazine into the tissue.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
187 words
A surgical instrument for stitching tissues by means of staples, comprising a support body with an open longitudinal channel; a jaw on said support body; a staple housing with a head, said staple housing being mounted in said longitudinal channel for longitudinal displacement therein, a pusher with a head, said pusher also being mounted in said longitudinal channel for displacement therein, said staple housing and said pusher being superposed with one thereof placed at the bottom of said channel, said staple housing and pusher being separable in transverse direction; a replaceable magazine with staples secured to the head of said staple housing, first drive means for moving said staple housing and said pusher to clamp tissue between said jaw and said magazine on the head of the staple housing, and second drive means for displacing the pusher relative to the staple housing to force the staples from said magazine into the tissue, said first and second drive means respectively including screw mechanisms arranged parallel to one another, one of said drive means including a handle movably and permanently connected to the rotary component of its screw mechanism.
Claim 2
Dependent Claim
187 words
A surgical instrument for stitching tissues by means of staples, comprising a support body with an open longitudinal channel; a jaw on said support body; a staple housing with a head, said staple housing being mounted in said longitudinal channel for longitudinal displacement therein, a pusher with a head, said pusher also being mounted in said longitudinal channel for displacement therein, said staple housing and said pusher being superposed with one thereof placed at the bottom of said channel, said staple housing and pusher being separable in transverse direction; a replaceable magazine with staples secured to the head of said staple housing, first drive means for moving said staple housing and said pusher to clamp tissue between said jaw and said magazine on the head of the staple housing, and second drive means for displacing the pusher relative to the staple housing to force the staples from said magazine into the tissue, said first and second drive means respectively including screw mechanisms arranged parallel to one another, one of said drive means including a handle movably and permanently connected to the rotary component of its screw mechanism.
Claim 3
Dependent Claim
41 words
A surgical instrument as claimed in claim 1, comprising means mounting the magazine on the pusher head to prevent relative transverse displacement therebetween and on the staple housing so that relative movement between the magazine and the staple housing is prevented.
Claim 4
Dependent Claim
33 words
A surgical instrument as claimed in claim 1, wherein the staple housing and pusher include respective rods having rectangular cross sections and contacting the walls of the longitudinal channel of the support body.
Claim 5
Dependent Claim
33 words
A surgical instrument as claimed in claim 1, in which the head of the staple housing is provided with an open slot, said head of the pusher being slidably inserted into said slot.
Claim 6
Dependent Claim
48 words
A surgical instrument as claimed in claim 3, in which the support body and the rods of the staple housing and the pusher arranged in said longitudinal channel thereof include longitudinal guides whose length is approximately equal to the relative displacement of the rods in a working stroke.
Claim 7
Dependent Claim
37 words
A surgical instrument as claimed in claim 1, in which the rotary component of the second drive means comprises a fixing device preventing turning of said rotary component when the pusher is in an initial inoperative position.
Claim 8
Dependent Claim
22 words
A surgical instrument as claimed in claim 3, comprising a handle for holding the instrument secured to the rod of said pusher.
Claim 9
Dependent Claim
73 words
A surgical instrument as claimed in claim 7, in which said handle of said one drive means is pivotally connected to the rotary component of its screw mechanism, said handle for holding the instrument having a recess in which the handle of said one drive means is engaged, in an initial inoperative position of the pusher, to prevent turning of the rotary element of the screw mechanism associated with said one drive means.
