Multifunctional posterior cranium opening drainage device for neurosurgery department

Abstract

The invention discloses a multifunctional posterior cranium opening drainage device for the neurosurgery department. The device comprises a top cover, an arc-shaped groove is formed in the top cover bottom surface, a fixed strip is fixedly installed on one side face of the top cover, a sliding groove is formed in the surface of the fixed strip, two sliding blocks are installed inside the sliding groove in a sliding mode, screw holes are formed in the two side faces of the fixed strip, one end of each screw hole is communicated with the outside world, the other end of each screw hole is communicated with the sliding groove, a bearing is installed on the end face, facing the corresponding screw hole, of each sliding block in an embedded mode, a screw is in threaded connection with each screwhole, one end of each screw is arranged in the outside world, a handle is fixedly installed at the end the of each screw, the other end of each screw extends into the sliding groove till being inserted into a corresponding bearing inner ring and fixed to the bearing inner ring in a welded mode, one end of each sliding block extends to the outside world along an opening of the sliding groove, andan opening rod is fixedly installed through a torsional spring. The device is simple in structure, the stability of opening is increased, the degree of opening can be effectively mastered, and the surgical safety is increased.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a multifunctional neurosurgery posterior cranial distraction drainage device. Background technique [0002] At present, when neurosurgery is performing surgical treatment on patients, due to the relatively dense nerve lines in the head, it is necessary to stretch the concave soft tissue on the back of the skull during head surgery, and at the same time, the brain is prone to effusion during surgery. It is necessary to drain the effusion out of the body through a drainage device. The previous craniocerebral distraction device has a single structure, which has poor stability and support for the patient's head, which is not conducive to the stability of the surgical operation. And the drainage tube is a simple tube body structure, which is easy to be blocked during use, so that the drainage tube needs to be replaced in real time, which increases the workload of medical staff to a cert...

Problems solved by technology

[0002] At present, when neurosurgery is performing surgical treatment on patients, due to the relatively dense nerve lines in the head, it is necessary to stretch the concave soft tissue on the back of the skull during head surgery, and at the same time, the brain is prone to effusion during surgery. It is necessary to drain the effusion out of the body through drainage equipment. The structure of the previous craniocerebral distraction device is single, which is poor for the stability and support of the patient's head, which is not conducive to the stability of the operation

Moreover, the drainage tube is a simple tube body structure, which is easy to be blocked during use, so that the drainage tube needs to be replaced in real time, which increases the workload of medical staff to a certain extent.
