<p>PCT No. PCT/FR96/01154 Sec. 371 Date Jan. 22, 1998 Sec. 102(e) Date Jan. 22, 1998 PCT Filed Jul. 23, 1996 PCT Pub. No. WO97/03713 PCT Pub. Date Feb. 6, 1997A surgical dissection instrument using a high-pressure liquid jet including a handpiece provided with a mechanism for generating and controlling the liquid jet. The handpiece has a simple design and is cheap to manufacture and may thus be a single-use handpiece. The handpiece is ergonomically shaped and may be held in one hand with all the function controls being operated by the fingers of the same hand. The instrument has a mechanism provided with a flexible tubing (13) for supplying the high-pressure liquid to the handpiece (10). The handpiece (10) has a squeezing mechanism for locally and momentarily closing off the flexible tubing (13) to cut off the supply of liquid: the mechanism consists of a moveable squeezing projection (25) on a hinged control handle (17), and a stationary squeezing projection (26) secured to the body (15) of the handpiece (10). The handpiece (10) has a mechanism (18) for locking the control handle (17) and cutting off the liquid jet.</p> |
