Craniotomy positioning guide template for neurosurgery

Abstract

The invention relates to craniotomy operation in a surgery, and solves the problem of difficulty in positioning in a craniotomy. A guide template mainly comprises an upper guide plate, a lower guide plate, a positioning cylindrical pin, a tooth positioning groove mask and a connecting and clamping bolt. The guide template has the main advantages that for a doctor, the operation is simple, the mounting and the dismounting are relatively convenient, and the guide template can be used without independent training; meanwhile, the positioning is relatively accurate, and the focus of a patient can be fully exposed, so that the doctor can perform the operation more smoothly; due to the characteristics of simple operation and very convenient mounting and dismounting, the time cost of the operationcan be greatly reduced; and for the patient, the guide template can be directly manufactured by utilizing a 3D printing technology, so that the cost is relatively low, and the fund pressure of the patient is relieved to a certain extent.

Description

technical field [0001] The invention relates to a positioning guide template for cutting skulls during neurosurgery operations. Background technique [0002] Craniotomy is one of the common surgical operations, also known as craniotomy, which refers to the use of instruments and equipment to open the human skull to expose the soft tissue inside the brain and perform unconventional treatment for brain lesions. Therefore, this treatment operation not only It only requires a very high level of surgical skills for doctors, and at the same time, cutting the skull in the correct position also has a great impact on the efficiency of its operation. [0003] When performing craniotomy, the current common method is to use CT or MRT scans to determine the lesion, and then determine the incision on the skull according to the lesion location and related anatomical positioning principles. Certain factors (such as position deviation, excessive incision, etc.) will affect the smooth operat...

AI Technical Summary

Problems solved by technology

[0003] When performing craniotomy, the current common method is to use CT or MRT scans to determine the lesion, and then determine the incision on the skull according to the lesion location and related anatomical positioning principles. Certain factors (such as position deviation, oversized incision, etc.) will affect the smooth progress of the operation

[0004] In order to accurately locate the craniotomy site and reach the lesion smoothly, it is often necessary to use an external positioning device. At present, in craniotomy surgery, it is more common to let the patient lie on the operating table, and then fix the head from both ends with hard objects. The disadvantage of this method is that the positioning is not stable enough, and the position of the craniotomy has a large accidental factor, which seriously affects the efficiency of the operation.

[0005] The traditional craniotomy process can usually be divided into three parts: first, medical personnel use a blade to clean the incision and the surrounding hair; second, use a surgical blade to cut the scalp along the coronal plane of the top of the head and peel it back and forth; Sawing and cutting the skull of the patient's lesion; relatively speaking, the first two steps do not require very high technical level of the doctor, but the third step is very dependent on the experience and technical level of the doctor

[0006] In the prior art, some can only be moved and positioned on a two-dimensional plane (Patent No.: 201320120883); although some can cut efficiently, they are still lacking in guiding and positioning (Patent No.: 201720298727.1); and some are cutting skulls It has good positioning and cutting effect, but its production cost is relatively high, and the operation is relatively complicated (patent number: 201721572274.3)
