Abstract
An apparatus for making surgical sutures in surgical operations, including a distal head part for making the sutures and receiving a cartridge containing staples and having a hollow punch, a control part at the other end and a flexible part transmitting to the distal head part control movements of the control part. The head part is detachable, and is not attached at the moment of insertion into the zone to be sutured. The head part is preferably replaced by a protective cap at the end of the flexible transmitting part. The protective cap allows easy insertion into an opening of a body part to be sutured. The cartridge is mounted to the head part in situ after the protective cap is removed and the head part is located in the zone in which the operation is to take place.

A method of suturing a tissue duct with a stapling apparatus, the stapling apparatus including:
- a distal head member comprising a staple supplying means adapted to receive surgical staples and further comprising an anvil against which said staples supplied from said staple supplying means are formed;
- a proximal control member having adjusting means disposed therein;
- drive means having a proximal and a distal end coupling said proximal control member and said distal head member, respectively said drive means transmitting control movements of said control member to said head member;
- said head member being removably detachable from said drive means, said distal end of said drive means being insertable into a tissue duct to be sutured through an opening in said duct when said head member is detached from said distal end of said drive means, said head member being attachable to said distal end of said drive means after said distal end has been inserted into said tissue duct, said distal end of said drive means having a diameter smaller than said distal head member whereby said distal end of said drive means may be easily inserted into an opening in a tissue duct;
- the method comprising inserting the distal end of the flexible drive means into an opening in the tissue duct, inserting the head member into the duct through another opening near a zone in which suturing is to take place, attaching the head member to the distal end at the zone in which suturing is to take place, and operating the control member of the stapling apparatus to make a suture.
A method of using a surgical stapler to suture a tissue duct comprising the steps of:
- inserting an end of a drive member of said stapler into an opening in the tissue duct, the drive member having a diameter consistent with the opening size;
- moving the end of the drive member toward a zone in which suturing is to take place;
- inserting a head member containing surgical staples into the tissue duct, the head member to be attached to the end of the drive member in the zone in which suturing is to take place;
- connecting the head member to the end of the drive member;
- and
- controlling the head member through the drive member to form a surgical suture with a control member of the stapler connected to an opposite end of the drive member.
Apparatus for making surgical sutures, comprising:
- a distal head member comprising surgical staple supplying means adapted to receive surgical staples and further comprising an anvil against which said staples supplied from said staple supplying means are formed;
- a proximal control member having adjusting means disposed therein;
- flexible drive means having a proximal and a distal end coupling said proximal control member and said distal head member, respectively, said drive means transmitting control movements of said control member to said head member;
- said head member being removably detachable from said drive means, said distal end of said drive means being insertable into a tissue duct to be sutured through an opening in said duct when said head member is detached from said distal end of said drive means, said head member being attachable to said distal end of said drive means after said distal end has been inserted into said tissue duct, said distal end of said drive means having a diameter smaller than said distal head member whereby said distal end of said drive means may be easily inserted into an opening in a tissue duct;
- said flexible drive means comprising a cable in a sheath, said proximal control member comprising means for moving said cable member in said sheath to effectuate relative movement of said staple supplying means and said anvil of said distal head member, said sheath of said distal end of said flexible drive means being detachably coupled to said anvil, adistal member in said sheath to effectuate relative movement of said staple supplying means and said anvil of said distal head member, said sheath of said distal end of said flexible drive means being detachably coupled to said anvil, a distal end of said cable detachably coupled to said staple supplying means, said control member moving said staple supplying means and anvil relatively together by transmission of a control movement through said cable of said flexible drive means such that said cable moves said staple supplying means toward said anvil to form said surgical staple and make a suture.
