Puncture positioning device for intracranial lesion based on brain stereotaxic 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 equipment, in particular to an intracranial lesion puncture positioning device based on a brain stereotactic system. Background technique [0002] With the development of imaging diagnosis technology, the detection of early intracranial tiny space-occupying lesions has become earlier and earlier, and the detection rate of brain tumors that require surgical treatment has also become higher. However, in the current clinical work, it is difficult to locate small intracranial lesions. Traditional craniotomy is difficult to locate. It is not easy to find lesions during surgical resection, resulting in large surgical incisions, large-scale brain tissue exposure, and easy damage during blind exploration of lesions. Brain tissue increases the incidence of trauma and complications in patients. For functional area tumors, traditional microsurgery can easily cause brain tissue damage in functional areas. The use of stereo...

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
