Posterior cranium distraction and drainage device for neurosurgery department

Abstract

The invention discloses a posterior cranium distraction and drainage device for the neurosurgery department, which comprises a pedestal, a liquid storage tank, a left posterior cranium distraction mechanism, a right posterior cranium distraction mechanism, a headrest, a drainage mechanism and a head stabilizing mechanism, wherein the headrest is arranged on the front portion of the upper end face of an operating table, two sets of stroke limiting air cylinders are installed between the pedestal and the headrest, the left posterior cranium distraction mechanism is mounted on the left side of the front part of the upper end surface of the operating table, and a right posterior cranium distraction mechanism is mounted on the right side of the front part of the upper end surface of the operating table; and a concave surface is arranged in the middle of the upper end face of the headrest, the head stabilizing mechanism is installed in the concave surface, a base plate is arranged on the lower portion of the headrest, and the drainage mechanism is installed at the front end of the upper end face of the operating table. The device is reasonable in structural arrangement, tissue such as skin muscles on the two sides of a craniotomy incision of a posterior cranium of a patient can be conveniently distracted to the two sides, the position of the distraction mechanism can be conveniently adjusted, the arrangement of the drainage mechanism does not affect the operation application space, the use and installation are more reliable, and the operation success rate of an operation can be increased.

Description

technical field [0001] The invention relates to the related technical field of medical devices, in particular to a neurosurgery posterior cranial distraction drainage device. Background technique [0002] At present, clinically, after craniocerebral surgery is performed on a patient, the patient's head needs to be avoided as much as possible. Since the intracranial blood vessels are rich and require multi-level separation, there is a lot of bleeding, and drainage after the operation is required. In the reference document "CN201711097116.1 A Neurosurgery Posterior Cranial Distraction and Drainage Device", it is mentioned in the specification that "the base is a "Zhu" type plate, and the upper surfaces of the two ends of the base are relatively fixed with fixing plates, The shaft hole of the fixed plate is provided with a rotating shaft, and the middle parts of the two rotating shafts are fixedly connected by an arc-shaped arm plate. There is a movable sleeve inside, and a ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a neurosurgery posterior cranial expansion and drainage device to solve the problem that the wall boards in the reference document proposed in the above background technology are arranged on both sides of the posterior skull, but it is inconvenient to expand the incision to both sides. The side skin and muscle and other tissues, and the negative pressure cylinder is located above the affected area, which will limit the operating space for the doctor to perform craniotomy, affect the operation, and it is not safe and convenient to use
