Crushing clamps
When is GI re-section required?
Re-section of bowel is required in cases of gangrene of the bowel (which may be caused by strangulation, thrombosis) or cancer.
The special instruments required are
· Crushing clamps
· Non-crushing clamps.
Crushing clamps
Crushing clamps are generally used with an objective to crush the muscle coat of the bowel thus obliterating the vascular supply.
These crushing clamps thus have
· Blades that are heavy and strong
· Blades of parker-Kerr are curved and of Lang-Stevenson are straight
· Loops for finger
· A catch for gradual crushing.
Identification points
· The instrument is heavy.
· The jaws appose closely.
· These occlude lumen and vessels.
· These are used on the segment that is removed from the body.
These clamps are of three types:
(a) Payr’s smaller crushing clamp
(b) Payr’s smaller clamps
(c) Parker-Kerr’s crushing clamps.
Identification points
· Payr’s gastric crushing clamps have heavy blades and handle.
· The joints are 4 and these double the force of action of the blades.
· The jaws have longitudinal serrations.
· The jaws are long so as to reach from lesser to greater curvature of stomach.
