Abstract

The invention provides a surgical tool, which comprises a surgical tool head and a rod portion. The surgical tool head is connected with the rod portion, the rod portion is a flexible rod and comprises a flexible core portion and a flexible sleeve with an inner cavity, and the flexible core portion is slidably positioned in the inner cavity. The surgical tool head comprises two forceps, and the flexible core portion and the flexible sleeve are connected with the two forceps respectively. The flexible core portion is capable of sliding relative to the flexible sleeve to realize relative opening-closing movement of the two forceps. The rod portion of the surgical tool can be freely bent into any shapes, so that the rod portion can be integrated on the flexible surgical tool, and a wide application range in a surgical process is realized.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a surgical tool. Background technique [0002] Surgical forceps are mostly used in relatively delicate operations such as brain surgery, microsurgery, ENT, obstetrics and gynecology, and hand surgery, and its scope of use is gradually expanding. Prior art forceps include a surgical tool head, a central stem, and an actuator. The surgical tool head and actuator are connected by a rod in the middle. The tail device in the prior art has a rigid structure and cannot be freely bent, so it cannot be integrated into a flexible surgical tool, which limits its application range. [0003] Therefore, there is a need in the art for a freely flexible surgical tool. Contents of the invention [0004] The object of the present invention is to provide a bipolar electrosurgical tool, comprising: a surgical tool head and a shaft, wherein the surgical tool head is connected to the shaft, whe...
