Abstract
The utility model discloses a neuroendoscope work passage with a core. The neuroendoscope work passage with the core comprises a plastic passage tube. One end of the plastic passage tube is provided with a hemispherical rubber plug, and the biggest section diameter of the rubber plug is approximately equal to the outer diameter of the plastic passage tube. The rear end of the rubber plug is provided with a draw rope or a draw rod. When the neuroendoscope work passage with the core is used, the end of the neuroendoscope work passage with the core is provided with the hemispherical rubber plug and is protruded into a brain body. Due to the fact that rubber is elastic and the rubber plug is of a hemispherical shape, surrounding brain organization can be effectively prevented from being damaged. When the front end of the neuroendoscope work passage with the core reaches an ill portion, the draw rope or the draw rod is pulled backward, and the rubber plug can be drawn out through the other end of the plastic passage tube. Therefore, a safe work passage is created for the neuroendoscope, operation of a doctor is facilitated, and secondary injuring for the surrounding brain organization of the ill portion is effectively avoided.
Description
Technical field
This utility model belongs to medical instruments field, particularly a kind of belt carcass nerve endoscope service aisle of auxiliary nervous scope work.
Background technology
At present; Neurosurgery develops into Wicresoft's epoch, and the nerve endoscope technology is one of less invasive techniques, if diseased region is darker; Be positioned within the brain essence; When nerve endoscope is inserted, often damage other good cerebral tissue, patient is caused secondary injury, how provide the service aisle of a safety present also unresolved for nerve endoscope.
Summary of the invention
The purpose of this utility model provides a kind of belt carcass nerve endoscope service aisle with regard to being to be directed against the defective of above-mentioned prior art, and the secondary to brain during this service aisle can effectively be avoided performing the operation injures.
Its technical solution is following: this utility model comprises the plastic of conduit pipe, and an end of plastic of conduit pipe is provided with the hemispherical rubber stopper, and the maximum cross-section diameter of rubber stopper approximates the plastic of conduit external diameter of pipe, and the rubber stopper rear portion is furnished with withdrawal cord or pumping rod.
This utility model in use; An end that this utility model is provided with the hemispherical rubber stopper probes into brain; Because rubber itself has elasticity and is hemispherical, the brain tissue around can effectively avoiding damaging is when this utility model front end arrives diseased region; Tractive withdrawal cord or pumping rod can be extracted out rubber stopper by the other end of plastic of conduit pipe backward.So just, can be nerve endoscope and create the service aisle of a safety, be convenient to doctor's operation and effectively avoided secondary injury the pathological changes surrouding brain tissue.
Description of drawings
Fig. 1 is the structural representation of this utility model.
The specific embodiment
Through accompanying drawing and specific embodiment this utility model is elaborated below:
As shown in Figure 1, this utility model comprises plastic of conduit pipe 1 and hemispherical rubber stopper 2, and the diameter of hemispherical rubber stopper 2 is equal to or slightly less than the external diameter of plastic of conduit pipe 1, and the rear portion of hemispherical rubber stopper 2 is connected with pumping rod 3.
The external diameter of above-mentioned plastic of conduit pipe 1 can be 16mm, and internal diameter is 14 mm, and length is 75mm.
Above-mentioned plastic of conduit pipe 1 preferably all selects for use transparent material to make with rubber stopper 2, so that observe at any time.
This utility model includes but are not limited to above embodiment, and it also can have other conspicuous variations, and for example the material of plastic of conduit pipe and hemispherical rubber stopper can be selected other alternative materials for use.
