Abstract
A laparoscopic scalpel includes a shaft and a recess disposed in a surface of the shaft proximal to a distal end of the shaft. A blade is attached to the shaft. The blade includes a cutting edge having a portion exposed by the recess and oriented outwardly from the recess. A proximal end of the portion of the cutting edge exposed by the recess is disposed further from the surface than is a distal end of the portion of the cutting edge exposed by the recess.

A laparoscopic scalpel, comprising:
- a shaft having a proximal end, a distal end, and a length therebetween;
- a recess disposed in a surface of the shaft, the recess having a proximal end and a distal end along the length of the shaft wherein the distal end of the recess is disposed proximal to the distal end of the shaft;
- and
