Stereotactic operation surface incision indicator and application method thereof in craniotomy

Abstract

The invention discloses a stereotactic operation surface incision indicator and an application method thereof in craniotomy. The indicator comprises a transparent matrix, a developing line and an adhesive layer, wherein the developing line is arranged in the transparent matrix; and the adhesive layer is arranged below the transparent matrix. The application method comprises the following steps: (1) sticking the stereotactic operation surface incision indicator to a fixed position on the scalp surface of a patient; (2) performing continuous scanning of skull CT on a patient wearing the indicator, so that a three-dimensional reconstructed indicator image can be seen on an operation planning system; and (3) determining an entry point of a puncture needle on real scalp of the patient according to different positions of the puncture needle of the operation planning system on the indicator. According to the stereotactic operation surface incision indicator disclosed by the invention, the scalp position corresponding to the cortical puncture point can be accurately positioned when a stereotactic operation is performed by a neurosurgeon, and intracranial hemorrhage and inaccurate target positions caused by operation errors can be reduced.

Description

technical field [0001] The invention discloses an orientation indicator and an application method thereof, in particular a body surface incision indicator for stereotactic surgery and an application method thereof in craniotomy, and belongs to the technical field of neurosurgery-related equipment. Background technique [0002] Craniotomy, also known as craniotomy, is a kind of cranial surgery, which refers to opening the patient's skull through mechanical equipment, so as to perform some unconventional treatments. For some special diseases, such as Parkinson's disease, epilepsy, etc., craniotomy is performed Treatment is necessary. Due to the high risk of craniotomy, a slight deviation will cause serious consequences to the patient. Therefore, in craniotomy, it is very important to locate the affected part to help the doctor operate correctly during the operation. At present, the commonly used positioning method is to fuse the head magnetic resonance image without the stere...

AI Technical Summary

Problems solved by technology

At present, the commonly used positioning method is to fuse the head magnetic resonance image without the stereotactic frame before the operation with the head CT image with the stereotactic frame during the stereotactic surgery, and then calculate the operation on the scalp, skull, The puncture entry point on the brain gyrus and the surgical path of the puncture target point are performed according to these calculation results. However, these plans are carried out virtually on the image data, and there is no device that allows the doctor to compare the incision on the image with the actual one. The skin of the patient's head is aligned, which may easily lead to errors in the position of the incision. In light cases, the doctor can eliminate the errors as much as possible based on rich experience, and in severe cases, it may have a slight impact on the patient's health.
