Abstract

The invention discloses tissue forceps. The tissue forceps comprise forceps handles (1) and forceps heads (2), wherein the forceps handles and the forceps heads are connected in a bendable manner.

Description

technical field [0001] The present invention relates to medical supplies. Background technique [0002] Tissue forceps are also called rat tooth forceps. The compression on the tissue is lighter than that of the vascular forceps, so it is generally used to clamp the soft tissue, which is not easy to slip off. For example, the lesion that has been excised is clamped and pulled to facilitate the operation. polluted. [0003] Existing tissue forceps are usually divided into pliers handles and pliers heads. The existing pliers handles and pliers heads are all integrally formed. The pliers heads and pliers handles cannot be bent, which is inconvenient and flexible during use. Contents of the invention [0004] The purpose of the present invention is to solve the above-mentioned problems, to provide a tissue forceps, comprising a handle and a head, the handle and the head are connected in a bendable manner, and the head is hinged on the handle , A fixed rod is hinged on the s...
