Visual hematocele cleaning device

Abstract

The invention discloses a visual hematocele cleaning device, and belongs to the technical field of medical instruments. The device comprises a guide handle, a sight glass, an optical fiber flexible wire, a flushing hose, a suction hose, a flushing foot switch, a controller, a flushing peristaltic pump, a medical negative pressure bottle, a flushing parameter display screen, a flushing parameter adjusting knob, a pipe joint, a peristaltic pump special pipe, a shielding box cover plate, a shielding box body, a flushing peristaltic pump power interface, a flushing peristaltic pump source switch and a normal saline bag. The flushing hose, the suction hose and the optical fiber endoscope simultaneously move forwards close to the inner side of a skull according to guidance through the guide handle entering the head, the guide handle has the function of locking the positions of a catheter and an optical fiber, flushing and suction are achieved through rotation of the external guide handle, the whole hematocele area can be covered, and it is guaranteed that brain tissue is not damaged; the intracranial hematocele condition can be clearly observed through the optical fiber sight glass; the flushing intensity is adjusted through the pulse type flushing peristaltic pump, and backflow is avoided. The device is easy to use and convenient to operate.

Description

technical field [0001] The invention relates to a device for cleaning hemocephalus with visualization, in particular to a device for brain surgery with flushing, suction and visualization functions, and belongs to the technical field of medical devices. Background technique [0002] At present, it is common clinically that a large space is formed between the skull and the brain tissue after brain atrophy in the elderly, and a large number of blood vessels are connected between the brain tissue and the skull. Hemocephalus compresses the brain tissue. After a long time, the effusion becomes viscous and has adhesions, which needs to be dealt with in time, otherwise serious lesions will occur. Craniotomy for this type of hemorrhage is very risky and costly for the patient. The optimal surgical plan is to open a small hole with a diameter of less than 20mm in the skull of the affected area, and then perform pulse washing and suction treatment with normal saline to dilute and suc...

AI Technical Summary

Problems solved by technology

[0006] The above two kinds of cleaning equipment have obvious shortcomings, and it is difficult to clean a large amount of blood between the skull and brain tissue through a small wound (the diameter of the surgical hole in the head is less than 20mm); and it is impossible to observe the operation process in real time, and it is impossible to observe the cleaning process and As a result of cleaning, there is no guarantee that the rinse hose will not touch the brain tissue and cause damage; and most of them are reusable instruments, which are easy to cause infection and increase the workload of decontamination
