发明名称 Surgical needle extractor having a disposable chuck, a chuck and a handle
摘要 A surgical needle extractor is provided which has a chuck including a penetration portion for penetrating between the claws of a surgical needle. The chuck also has an actuated piece pivotable with respect to the penetration portion of the chuck. The extractor includes a handle to which the chuck is releasably attached. The handle includes pivoting means for pivoting the actuated piece with respect to the penetration portion such that when the penetration portion is inserted between the needle claws, the penetration portion and the actuated piece cooperate to remove the needle. Only the chuck touches the patient's skin, and only the handle is touched by the operator. Accordingly, the handle need not be sterilized each time before use and the chuck is disposable. The actuating rod of the handle is adapted to be hand-operated. The extractor can further include means for releasing the chuck from the handle when a new chuck is desired to be attached to the handle. Both the chuck and the handle can be formed as unitary members.
