Abstract
Abstract A surgical instrument includes a forceps unit for being positioned within an anatomical cavity. The forceps unit includes a housing, an outer tubular member, an intermediate tubular member, and a handle mechanism coupled with at least one of the intermediate and outer tubular members for creating relative movement between the intermediate and outer tubular members. The outer tubular member has a proximal end mounted by the housing and terminates distally at a distal end. The intermediate member has a tubular body disposed telescopically within the outer tubular member, a proximal end mounted by the housing and a pair of opposed jaws disposed on a distal end of the tubular body resiliently biased apart such that relative movement of the outer tubular member distal end over the jaws causes the jaws to close. A channel or passage is defined through the instrument to permit an inner member having an end effector to be inserted therethrough.

An instrument as recited in claim 1, wherein said jaws are formed integrally with said body.
Claim 5
Dependent Claim
25 words
An instrument as recited in claim 1, wherein said jaws are formed separately from said body and are attached to said body by coupling means.
Claim 6
Dependent Claim
26 words
An instrument as recited in claim 1, wherein each of said jaws define a recessed portion and an insert is removably disposed in each recessed portion.
Claim 7
Dependent Claim
34 words
An instrument as recited in claim 2, further comprising an inner member movably disposed in said tubular body, said inner member having an end effector on a distal end for performing a medical procedure.
Claim 8
Dependent Claim
14 words
An instrument as recited in claim 1, wherein both of said jaws are movable.
Claim 9
Dependent Claim
21 words
An instrument as recited in claim 1, wherein one of said jaws is fixed and one of said jaws is movable.
Claim 10
