Abstract
Dissecting cum-haemostapling scissors comprise an upper and lower jaw members having handles provided with cooperating lock elements. The lower jaw member has a longitudinal slit accommodating a pivotable spring-biased cutting blade. When the handles are gradually brought together, haemostatic grooves provided in both members firstly nip tubular blood vessels on either side of the blade, and then the blade cuts the blood vessel. The upper jaw member is also provided with a set of haemostaple pins in a slit housing provided in the upper jaw member. By further operation of the handles, a blunt end of the blade actuates or triggers a haemostapling system which releases a staple from a staple magazine and the staple clasps firmly the severed ends of the blood vessel. The lower jaw member is further provided with an automatic alignment system to align blood vessels with a cutting edge of the blade.
