Posterior cranium distraction and drainage device in neurosurgery department

Abstract

The invention relates to the technical field of medical apparatuses, in particular to a posterior cranium distraction and drainage device in the neurosurgery department. The posterior cranium distraction and drainage device comprises a bottom plate, a liquid storage tank, a supporting plate, an electric push rod, a transverse plate, a first installation rod, a first connecting rod, a second installation rod, a second connecting rod, a C-type plate, a rectangular slider, a distraction plate, a fixed base, a drainage tube and an ear washing ball. In the posterior cranium distraction and drainagedevice, brain nerves can be effectively fixed through a sawtooth-shaped structure at the bottom of the distraction plate, the phenomenon that the brain nerves slip off the supporting plate is reduced, the separation of the brain nerves to the maximum extent is ensured, and it is ensured that surgery is normally conducted; after the ear washing ball is squeezed, the ear washing ball is inserted inthe other end of the drainage tube, through the fluid pressure intensity difference, hydrops in a brain are smoothly sucked out, and the posterior cranium brain tissue is protected against injuries;the ear washing ball is squeezed through different squeezing intensity, and the pumping speed of posterior cranium intracerebral hydrops by the drainage tube can be controlled; the elongation of an electric push rod is adjusted, and the aim of adjusting the installation heights of the distraction plate and the drainage tube can be realized.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a neurosurgery posterior cranial distraction drainage device. Background technique [0002] Neurosurgery is a branch of surgery, which uses unique neurosurgery research methods to study the human nervous system, such as the brain, spinal cord and peripheral nervous system, as well as related diseases, based on surgery as the main treatment method. Subsidiary organs, such as skull, scalp, cerebrovascular meninges and other structural injuries, inflammation, tumors, deformities and certain genetic metabolic disorders or dysfunctional diseases, such as: the etiology and pathogenesis of epilepsy, Parkinson's disease, neuralgia and other diseases , and explore new diagnostic, therapeutic, and preventive technologies as a high-level, precise, and cutting-edge discipline. Neurosurgery mainly treats diseases of the brain, spinal cord and other nervous systems caused by trauma, s...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned patent documents can stretch the back of the cranium, the two ends of the stretching plate are stretched through the adjustment of the second electric telescopic rod. The range of motion in this process is relatively large, which may damage the back of the brain. It cannot adjust the expansion plate flexibly, and the operation accuracy is small

Moreover, it can drive the drainage tube to move left and right through the third electric telescopic rod. This process cannot flexibly adjust the drainage tube, which not only reduces the efficiency of extracting the effusion, but also cannot effectively control the rate of extracting the effusion. May also damage posterior brain tissue

In addition, its installation height cannot be adjusted, which is very inconvenient to use
