Description

Flexible bladder surgical instrument

Technical Field

The utility model relates to the technical field of medical appliances. More particularly, the present utility model relates to a flexible bladder surgical instrument.

Background

In the operation process for treating bladder diseases, medical staff has a phenomenon that the actuating device (namely, a clamp head or a tool bit) of the surgical instrument needs to be adjusted at multiple angles in the whole bladder due to the position of a focus, so that a connecting structure connected with the actuating device of the existing bladder surgical instrument is designed into a structure with adjustable angles in many cases. For example, chinese patent publication No. CN213047255U discloses a multifunctional urological surgical instrument. In this patent document, the connecting structure of the actuating device (i.e. the cutter head assembly) of the surgical instrument is provided as a bendable first outer tube, whereby a multi-angle adjustment of the actuating device throughout the bladder is achieved. However, the bending principle of the first outer tube is that the material of the first outer tube is medical elastic rubber. That is, the bending function of the first outer tube is determined by the material thereof. Thus, when the surgical instrument enters the bladder, the medical staff cannot adjust the angle of the execution device at any time. This brings great inconvenience to medical staff.
