pDissecting-cum-haemostapling scissors have upper and lower jaws 10, 30 with prongs 13, 33, and handles 46,49 which when pressed together engage a series of locks 51, 52. A blood vessel may be dissected out using the prongs and held between the jaws. Successive operation of the locks then causes 1) haemostatis, as the vessel is nipped between haemostatic grooves in the upper and lower jaws, 2) cutting, by means of a disposable blade mounted in slit 35, and 3) haemostapling, by means of optional stapling magazines in the upper jaw. The locks are then released by the action of spring 48. The scissors may also incorporate a vessel alignment device and an electrode holder and have the advantage that several processes may be carried out using a single instrument. IMAGE/p [GB2233903A]
