Encephalic lesion puncture positioning device based on brain stereotaxis system

Abstract

An encephalic lesion puncture positioning device based on a brain stereotaxis system comprises a positioning ball, a flexible guiding wire and a circular tube shaped puncture needle tube, wherein the diameter of the positioning ball is greater than the outer diameter of a puncture needle, one end of the guiding wire is fixedly connected to the positioning ball, the other end of the guiding wire can penetrate through an inner tube hole formed in the puncture needle tube, and the end face, located at a puncture head end, of the puncture needle tube is mutually matched with the side face, connected with the guiding wire, on the positioning ball in an attaching mode.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device for puncturing and positioning intracranial lesions based on a brain stereotaxic system. Background technique [0002] With the development of imaging diagnostic technology, early detection of small intracranial space-occupying lesions has become earlier, and the detection rate of brain tumors requiring surgical treatment has also become higher and higher. However, it is difficult to locate small intracranial lesions in clinical work at present. Traditional craniotomy is difficult to locate. The lesion is difficult to find during surgical resection, resulting in large surgical incisions and large-scale exposure of brain tissue. Blindly detecting lesions can easily damage other organs Brain tissue increases the incidence of trauma and complications in patients; for tumors in the functional area, traditional microsurgery can easily cause damage to the brain tissue in the fun...

Problems solved by technology

[0005] The purpose of the present invention is to provide a puncture positioning device for intracranial lesions based on the brain stereotaxic system, and the technical problem to be solved is: the puncture needle used in the existing brain stereotaxic system needs to be placed after repositioning to the intracranial lesion In the intracranial, due to brain tissue displacement, collapse and other reasons, the positioning needle is easy to cut the brain tissue around the lesion, and it will also cause inaccurate positioning; while the traditional positioning needle or positioning guide wire probe head has a retractable or radial Pops open to release grippers that grab hold of the mass, but such structures are not suitable for very soft intracranial tissue
