First Claim
Patent Images
1. A surgical device comprising:
- an elongate hollow shaft having a distal end and a proximal end;
a plurality of electrically conductive flexible ribs connected to said distal end of said shaft and to one another to form a cage;
dissection means, operatively connected to said ribs via said proximal end of said shaft, for electrically energizing said ribs, whereby an organic body inserted between said ribs can be cut into segments; and
means including a plunger member slidably inserted through said shaft and having a distal and engageable with said organic body for pushing said organic body in a distal direction against said ribs during a slicing procedure.

Abstract
A laparoscopic surgical device comprises an elongate shaft having a plurality of electrically conductive flexible ribs connected to the distal end of the shaft and to one another to form a cage or basket. Upon placement of an organic body in the cage, the ribs are electrically energized. The organic body is pressed against the ribs to dissect the ribs in a single cauterization operation.

5. A surgical method comprising the steps of:
-
providing a surgical device having an elongate shaft provided at a distal end with a plurality of electrically conductive flexible ribs connected to one another to form a cage; inserting said cage in a collapsed configuration into an abdominal cavity of a patient through an opening in an abdominal wall of the patient; upon insertion of said cage into the abdominal cavity of the patient, opening said cage from said collapsed configuration to an opened configuration; upon the opening of said cage, placing an organic body into said cage in said abdominal cavity; electrically energizing said ribs; and during said step of electrically energizing and upon placement of said organic body into said cage, forcing said organic body and said cage against one another, thereby slicing said organic body into segments in an electrocautery operation. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A surgical method comprising the steps of:
-
providing a surgical device having an elongate shaft provided at a distal end with a plurality of electrically conductive flexible ribs connected to one another to form a cage; inserting said cage into an abdominal cavity of a patient through an opening in an abdominal wall of the patient; placing an organic body into said cage in said abdominal cavity; electrically energizing said ribs; and during said step of electrically energizing and upon placement of said organic body into said cage, forcing said organic body and said cage against one another, thereby slicing said organic body into segments in an electrocautery operation, said step of forcing including the step of closing said ribs about said organic body by drawing said shaft and said cage in a proximal direction relative to a tubular member surrounding said shaft, thereby urging said ribs towards one another. - View Dependent Claims (16)

17. A surgical method comprising the steps of:
-
providing a surgical device having an elongate hollow shaft provided at a distal end with a plurality of electrically conductive flexible ribs connected to one another to form a cage, said shaft being longitudinally traversed by a plunger member; inserting said cage into an abdominal cavity of a patient through an opening in an abdominal wall of the patient; placing an organic body into said cage in said abdominal cavity; electrically energizing said ribs; and during said step of electrically energizing and upon placement of said organic body into said cage, forcing said organic body and said cage against one another, thereby slicing said organic body into segments in an electrocautery operation, said step of forcing including the step of pressing said organic body against said ribs by shifting said plunger member in a distal direction relative to said cage. - View Dependent Claims (18)
