Abstract
Abstract A surgical instrument 10 is provided for the morcellation of bodily tissue or bodily organ parts during an endoscopic surgical procedure. The instrument includes a handle assembly 12, a tubular body portion 14 extending from the handle assembly and defining a longitudinal axis, a tool assembly 16 associated with a distal end of the tubular body including cooperating jaw members 28, 30 and a cutting member 34, a first mechanism 17 for effectuating remote actuation of the cooperating jaw members and a second mechanism 19 for effectuating remote reciprocal movement of the cutting member with respect to the longitudinal axis of the tubular body.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
41 words
A surgical apparatus for fragmenting tissue comprising: a securing mechanism defining an inner cavity; and a cutting member provided in the inner cavity; wherein the securing mechanism holds the tissue preparatory to the fragmenting of the tissue by the cutting member.
Claim 2
Dependent Claim
27 words
A surgical apparatus as recited in Claim 1, wherein the securing mechanism includes a pair of cooperating jaw members configured for use in remote securing of tissue.
Claim 3
Dependent Claim
35 words
A surgical apparatus as recited in Claim 2, further comprising a first actuation mechanism associated with the cooperating jaw members for remotely actuating the cooperating jaw members between an open position and a closed position.
Claim 4
Dependent Claim
17 words
A surgical apparatus as recited in any of the preceding claims, wherein the inner cavity is rigid.
Claim 5
Dependent Claim
30 words
A surgical apparatus as recited in any of the preceding claims, further comprising a second actuation mechanism operatively associated with the cutting member for effecting movement of the cutting member.
Claim 6
Dependent Claim
26 words
A surgical apparatus as recited in any of the preceding claims, wherein the movement of the cutting member is reciprocal with respect to the inner cavity.
Claim 7
Dependent Claim
44 words
A surgical apparatus as recited in any of the preceding claims, further comprising a handle assembly; a body portion extending from the handle assembly and defining a longitudinal axis wherein the jaw members are associated with a distal end portion of the body portion.
Claim 8
Dependent Claim
21 words
A surgical apparatus as recited in any of the preceding claims, wherein each of the jaw members is provided with teeth.
Claim 9
Dependent Claim
21 words
A surgical apparatus as recited in any of the preceding claims, wherein the cutting member includes an arcuately configured cutting blade.
Claim 10
Dependent Claim
38 words
A surgical apparatus as recited in any of the preceding claims, further comprising a second actuation mechanism associated with the cutting member for effectuating reciprocating, arcuate movement of the cutting member within the at least one jaw member.
Claim 11
Dependent Claim
43 words
A surgical apparatus as recited in any of the preceding claims, wherein the second actuation mechanism includes a handle member pivotally connected to the handle assembly and at least one actuation arm, the actuation arm interconnecting the handle member to the cutting member.
Claim 12
Dependent Claim
45 words
A surgical apparatus as recited in any of the preceding claims, further comprising a bore portion having a longitudinal axis defined by a longitudinal axis of the apparatus for accessing the cutting member, the bore being dimensioned to be capable of pulling fragmented tissue therethrough.
Claim 13
Dependent Claim
20 words
A surgical apparatus as recited in Claim 12, wherein the bore is dimensioned for reception of a grasping member therethrough.
Claim 14
Dependent Claim
51 words
A surgical apparatus as recited in Claim 13, wherein the grasping member has an elongated body portion including a tool assembly associated with a distal end, and a handle mechanism associated with a proximal end to effectuate remote actuation of the tool assembly between an open position and a closed position.
Claim 15
Dependent Claim
25 words
A surgical apparatus as recited in any of the preceding claims, wherein the securing mechanism is dimensioned and configured for insertion through a trocar cannula.
