Surgical positioning device for intracranial lesions

Abstract

The invention discloses a surgical positioning device for intracranial lesions. The surgical positioning device comprises a guide plate base, a guide plate support, bosses and support clamping bases,wherein the guide plate base is arranged in a facial anatomy marking area of a patient, and a first groove is formed in the guide plate base; the bosses and the support clamping bases are separately arranged at the two ends of the guide plate support; projections of the guide plate support, the bosses and the support clamping bases are of concave-shaped structures, and a second groove is formed inthe end face of the guide plate support; the bottom face of the second groove is a curved face and is used for forming a guide pipe tunnel through which a guide pipe passes; the bosses are separatelyinserted into the first groove in a matching manner; the guide plate support is separately connected with the guide plate base; the support clamping bases separately and tightly press scalp of the patient toward the end face of the head of the patient, and an intersection point formed by the direction of a central line of the guide pipe tunnel, the scalp surface of the patient and the surface ofa deep skull is set as a puncturing central point of the intracranial lesions surgery. The surgical positioning device for the intracranial lesions provided by the invention is convenient to use, is small in size, and can improve the puncturing accuracy of the intracranial lesions surgery.

Description

technical field [0001] The invention relates to the technical field of medical surgical instruments, in particular to a surgical positioning device for intracerebral lesions. Background technique [0002] Cerebral hemorrhage is a common disease in neurosurgery. Cerebral hemorrhage has a high disability and fatality rate. During the treatment of cerebral hemorrhage, it is often necessary to perform surgery to remove the intracerebral hematoma as soon as possible. The key to the success of cerebral hemorrhage surgery lies in the precise positioning of the intracerebral hematoma by the surgeon. . At present, in the operation of cerebral hemorrhage, the doctor's freehand puncture method is more common, but the success of the puncture mainly depends on the experience and feeling of the operator, which has great uncertainty and risk. [0003] The existing accurate positioning systems for intracerebral lesions used in cerebral hemorrhage surgery are mainly frame stereotaxic instru...

AI Technical Summary

Problems solved by technology

[0003] Existing accurate positioning systems for intracerebral lesions used in cerebral hemorrhage surgery are mainly frame stereotactic instruments and frameless stereotactic navigation instruments; however, these two types of medical equipment are expensive and bulky; they are not conducive to popularization in most medical treatments. Institutions, especially primary care units;
