Repeating titanium clamp pincers
InactiveCN101617950AAvoid the risk of sheddingIncrease the speed of surgerySuture equipmentsSurgical staplesWide fieldTitanium
The invention discloses repeating titanium clamp pincers, which comprise a pincer body and a nail storage for filling a titanium clamp. When in use, the clip storage is inserted into the pincer body, and a handle is pinched to realize the clamp-closure of the titanium clamp and is released to finish the automatic filling of the next titanium clamp. The repeating titanium clamp pincers can effectively improve the operative speed, shorten the length of operation and reduce the probability of falling off of the titanium clamp when apparatuses are passed; in addition, only the titanium clamp and the nail storage are disposable apparatuses, while the pincer body can be sterilized and repeatedly used, thus the cost on use of the repeating titanium clamp pincers is low and economical burdens of patients can be relieved; besides, bended pincer heads can provide wider field of view and internal-mounted structural parts are beneficially for being prevented from contaminating by the operation.
