Surgical anastomosis device
First Claim
1. A surgical device for inserting an anastomosis ring, having first and second separable unitary members formed to interlock, together, into upper open and lower open ends of a tubular anatomic member and for closing said first and said second unitary members together to join said upper and loer ends;
- said surgical device comprising;
distal adapter means configured for temporarily mounting a first unitary member so that said first unitary member can be secured within said upper open end of said anatomotic member, said distal adaptor means including a hollow distal sleeve and first alignment means for aligning the first unitary member on said distal sleeve, said first alignment means being axially movable within said distal sleeve and biased in a first direction;
proximal adaptor means configured for temporarily mounting a second unitary member so that said second unitary member can be secured within said lower open end of the anatomic member, said distal adaptor means being separable and independently manipulable from said proximal adaptor means; and
actuating means, connected to said proximal adaptor means, for engaging said distal adaptor means and for drawing it relative to said proximal adaptor means thereby to interlock said first unitary member temporarily mounted on said distal means and said second unitary member temporarily mounted on said proximal adaptor means and for releasing said distal adaptor means from said first unitary member and said proximal adaptor means from said second unitary member.

Abstract
A transanal insertion device for surgically inserting an anastomosis ring having two unitary members into a tubular anatomic member comprises a distal adapter, a proximal adapter and an actuator. The distal adapter includes a hollow distal sleeve and a spring-loaded distal spool axially movable within the distal sleeve. The distal spool is biased in a first direction by a distal spring and includes alignment fingers pivotably connected thereon for aligning a first unitary member. The proximal adapter has a hollow proximal sleeve and a spring-loaded proximal spool axially movable within the proximal sleeve. The proximal spool is biased in a second direction by a proximal spring and includes alignment fingers connected thereon for aligning a second unitary member. The proximal member also includes a proximal gripper for securing the second unitary member on the proximal hollow sleeve. The actuator includes an elongated tube with a collar connected to its distal end and a handle assembly connected to its proximal end. First and second flexible rods connected to the handle assembly extend through the elongated tube. The flexible rods are manipulated to engage the distal adapter and draw it relative to the proximal adapter. The rods are also manipulated to release the distal and proximal adapters from their respective unitary members so the distal adapter, the proximal adapter and the actuator can be withdrawn transanally.
