Medical craniocerebral operation channel sealing apparatus

Abstract

The invention relates to medical craniocerebral operation channel sealing apparatus. The sealing apparatus comprises an expandable water bag and a supporting frame, wherein the expandable water bag comprises an elastic water bag, a water pipe and a valve, the supporting frame comprises an outer fixing support, a smooth plate and a supporting column, one end of the water pipe is connected with thevalve, the other end of the water pipe is connected with an opening hole of the elastic water bag, the front face of the smooth plate is fixedly connected with the side face of the elastic water bag,the back face of the smooth plate is fixedly provided with the supporting column, and the outer fixing support is fixedly connected with the supporting column. The sealing apparatus can be inserted between the scalp and skull through the outer fixing support and is stably fixed to the scalp and skull, and a proper amount of sterile normal saline is pushed into the elastic water bag from the valvethrough an injector and the valve is closed, so that the elastic water bag is rapidly expanded and inflated, the inflated elastic water bag abuts against tissues such as the skull or scalp muscles, anoperation channel is rapidly and tightly sealed, the brain tissue is isolated from the outside, the cerebrospinal fluid loss is prevented, the brain tissue deformation is reduced, the stimulation ofair and the like to the brain tissue is reduced, and the situation that the intracranial water environment is not disturbed by the outside is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical operation equipment, in particular to a medical cranial operation channel sealing device. Background technique [0002] The basic process of craniocerebral surgery is divided into three stages, craniotomy, intracerebral surgical operation, and cranial closure. After the surgical field was disinfected and sterile towels were spread, the craniotomy procedure was started: the scalp was cut, the skin flap was opened, and then the skull flap was incised and freed with tools, and the dura mater was incised. Then, intracerebral surgery was performed, and after the end, the cranial closure procedure was performed: the dura mater was sutured, the skull was fixed with a nail plate, and the scalp incision was sutured. It takes at least about 1-2 hours to complete the routine cranial closure procedure (related to the proficiency of the operator). [0003] In the process of intracerebral surgery, deep brain ...

AI Technical Summary

Problems solved by technology

[0013] Based on this, it is necessary to provide a medical craniocerebral operation channel sealing device in view of the many safety problems such as the above-mentioned lax channel sealing and unstable fixation in the current surgical channel sealing method.
