Multi-pipe-diameter flushing device used in neurosurgery

Abstract

The invention relates to the technical field of medical instruments, and discloses a multi-pipe-diameter flushing device used in neurosurgery. The multi-pipe-diameter flushing device used in neurosurgery comprises a first water outlet pipe, a water inlet pipe, a regulation and control assembly and a water control part for controlling the water outlet of the water inlet pipe, wherein the first water outlet pipe and the water inlet pipe are connected with the water control part through the regulation and control assembly, a plurality of pipe cavities with the same length as that of the first water outlet pipe are formed in the first water outlet pipe, the diameters of the pipe cavities are different, the regulation and control assembly comprises a gear shifting control and a gear shifting part, the gear shifting control is provided with a notch, the gear shifting part is connected with the gear shifting control and can drive the gear shifting control to rotate so that the notch can correspondingly communicate with the water inlet pipe and any pipe cavity, and the water control part is connected between the regulation and control assembly and the water inlet pipe and can close and open the water outlet of the water inlet pipe. By means of the arrangement, the problem that an existing flushing device cannot flexibly replace pipe openings with different calibers according to actualrequirements in an operation, namely, cannot be suitable for flushing under naked eyes with a large amount of water and microsurgery at the same time is solved.

Description

technical field [0001] The present application relates to the technical field of medical devices, and more specifically, relates to a multi-diameter flushing device used in neurosurgery. Background technique [0002] During neurosurgery, in order to clear the blood exposure field, reduce the thermal damage caused by electrocoagulation and electric knife, and remove the bone ground out during the craniotomy, irrigation is often required. The devices used include flexible needles Syringe and elastic suckable water polo, and these two kinds of devices have the following disadvantages: (1) water polo with bigger caliber is often used when flushing with a large amount of water under the naked eye, and when micromanipulation is carried out under a microscope, then need to change caliber Small syringes with hose needles are used for flushing, which makes it necessary to switch between different flushing devices during the entire operation; (2) the capacity of the syringe and water ...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the problems in the related art at least to a certain extent, the purpose of this application is to provide a multi-diameter flushing device for neurosurgery, which can solve the problem that the existing flushing device cannot be flexibly replaced according to the actual needs of the operation. The problem of rinsing with a large diameter nozzle, that is, it cannot be applied to the problem of large water volume under the naked eye and microsurgical rinsing at the same time
