International Classification:

A61B 18/18

US Classification:

606 51, 606 50

Abstract:

An electrosurgical instrument includes a housing having a shaft attached thereto which connects a pair of first and second jaw members such that the jaw members are movable relative to one another to grasp tissue therebetween. The instrument also includes a four-bar handle assembly attached to the housing for actuating a drive rod assembly. The handle assembly includes a handle and a cam-like piston which cooperate to impart a uniform closure pressure against tissue grasped between the jaw members. The instrument also includes a rotating assembly for rotating the jaw members, a knife assembly for separating tissue and a pair of electrical leads connect the jaw members to a source of electrical energy. The electrical leads include slack loops disposed in the rotating assembly which permit rotation of the jaw members about the axis.

US Classification:

128898, 2271791, 2271751, 227 19

Abstract:

An apparatus for forming an anastomosis between adjacent intestinal sections of tissue is provided. The apparatus includes a circular surgical stapler having an anvil assembly with an anvil shaft and an anvil, the circular surgical stapler further having a tubular body portion with an annular knife and a body portion shaft selectively attachable to the anvil shaft; and a seal structure for deposition between the intestinal sections of tissue including a hub configured to engage attachment structure on at least one of the anvil shaft and the body portion shaft. The attachment structure is positioned so that the seal structure is located between the intestinal sections of tissue when the circular surgical stapler is disposed within the intestinal sections of tissue.

International Classification:

A61B 17/04

US Classification:

2271791, 2271751

Abstract:

An assembly for joining tissue is provided and includes an anvil assembly and a body portion juxtaposed with respect to one another along a shaft and arranged so as to be approximated with respect to one another; and an applicator supported on the anvil assembly and configured for retaining a wound treatment material therein and for dispensing the wound treatment material therefrom. A method for joining tissue is provided and includes the steps of dispensing the wound treatment material from the applicator so as to distribute wound treatment material onto at least one of a first tissue section and a second tissue section; and approximating the anvil assembly and the body portion to one another so that the first tissue section and the second tissue section are in contact with one another with the dispensed wound treatment material interposed there between.
