HTJ-I type minimally invasive and directional operation instrument of brain

Abstract

The invention provides minimally invasive brain stereotactic operation equipment capable of reducing risk of a patient. In a brain operation, a damage free positioning frame, a gun-shaped skull drill suite, a positioning rule, a positioning block series, a puncture transplant injection needle, a limiting stopper and a spiral brain biopsy needle are used, the brain CT or MRL is unnecessary to be repeatedly made, and the puncture thickness is necessarily measured by a ruler; and according to the designed geometric space coordinate of the equipment, a target point can be reached by direct puncture, so the equipment has the advantages of convenience and flexibility, and reduces risk and cost of the patient.

Description

Technical field [0001] The patent of the present invention relates to a minimally invasive brain-directed surgical instrument. The patent of the present invention is convenient and flexible to use, especially without repeating head CT or MRI; the puncture depth does not need to be measured by a ruler during the operation, and is designed according to the geometric space coordinates of the instrument. The target point can be accurately reached, the intraoperative operation stability is high, the surgical trauma is minimal, and the incidence of complications is extremely low. Background technique [0002] At present, the traditional stereotaxic instrument requires the patient to install a stereotaxic frame on the head, and re-scan with CT or MRI. The operation is cumbersome and time-consuming, which may delay the golden time for optimal treatment, and increase the risk of patient pain and infection and bleeding. medical expenses. Contents of the invention [0003] In order ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the defects of the traditional stereotaxic instrument used in the existing brain-directed surgery, the patent of the present invention provides a HTJ-I type minimally invasive brain-directed surgical instrument

This system can not only effectively solve or reduce the problems of cumbersome operation, increased patient pain, infection and bleeding, time-consuming and labor-intensive and safety problems existing in the prior art, but also can strive for more treatment time and improve curative effect.
