Problems solved by technology

The nozzle of the existing high-pressure water jet surgical device can only spray high-pressure water, and the trajectory of the high-pressure water jet needs to be moved by the doctor's hand along the resection trajectory. The operation efficiency is low, and the technical requirements for the doctor are quite high

Abstract

A rotary water jet device for surgery comprises a high-pressure water pump, an installation cylinder and a handle arranged on the upper portion of the outer side of the installation cylinder. The installation cylinder is internally provided with an upper bearing block, a lower bearing block, a drive motor and a rotary sealing connection device. The upper bearing block and the lower bearing block are internally and rotationally connected with a hollow transmission shaft through a first bearing and a second bearing respectively, and a connection hole is formed in the center of the upper end of the hollow transmission shaft. The lower end of the rotary sealing connection device and the upper end of the hollow transmission shaft are coaxially fixed and in sealed connection, and the lower end of the hollow transmission shaft is provided with a rotary jet device located on the lower portion of the installation cylinder. The rotary water jet device is novel in design, compact in structure, convenient to operate, good in sealing performance, safe and reliable, the radius of jet can be adjusted according to the size of lipomas or fibromas so as to cut off lipomas or fibromas at a time, operation time is greatly shortened, and the rotary water jet device does not need to be moved in the operation process and is suitable for being operated by doctors with different experience.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a rotary water jet device for surgical operation. Background technique [0002] Clinically, when extracting sarcoma such as lipoma or fibroid, the lipoma or fibrous part is generally clamped with surgical forceps, and then cut with a scalpel. It is extremely difficult to work, and it is necessary to equip different surgical tools according to the size of the lipoma or fibroid, and it is necessary to fix the part of the lipoma or fibroid for resection, which is difficult and brings great pain to the patient. [0003] In recent years, with the increasing development of science and technology, high-pressure water jet surgical devices have been gradually applied. The nozzle of the existing high-pressure water jet surgical device can only spray high-pressure water, and the trajectory of the high-pressure water jet needs to be moved by the doctor's hand along the resection trajectory. The oper...
