Embodiment Construction

[0013] The technical solutions in the embodiments of the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention and two clinical cases.

[0014] Case 1 (location of midline structural lesions): This patient has a supratentorial midline posterior tumor. After the patient shaved his head before surgery, the positioning ruler was attached to the midline of the brain in a sagittal direction, and preoperative brain CT was performed an examination. After the examination, the sagittal image can be selected on the cranial CT to find out the CT scan through the ulnar chain series, which can be displayed on the body surface according to the geometric relationship between the lesion and the chain (see image 3 ), so as to locate the three spatial positions of the lesion on the scalp, which can further guide the surgical plan. image 3 The middle AOB is the projection of the lesion in the sagittal position, and point C is...

Abstract

A novel intracranial lesion scalp positioning ruler belongs to the medical equipment industry and is used for accurate positioning of intracranial lesions. The positioning ruler is mainly composed of metal hollow balls and hollow cylinders. The metal balls and columns are arranged in an orderly manner and fixed on the soft tape. Adhesive stickers are attached under the tape, which can be tightly adhered to the scalp. The ruler tape is 15cm long and 2.5cm wide, and the two sides are composed of spheres and cylinders in a symmetrical chain shape. The hollow sphere is the main body, and cylinders are placed at 4cm, 9cm, and 13cm to separate them; the middle area is 3cm, 6cm, and 12cm. The tape is divided into four areas: I, II, III, and IV. Adhere the tape to the patient's head before the operation, and perform brain CT examination, which can quickly and accurately determine the three-dimensional position of the intracranial lesion in the brain, which is conducive to the precise puncture of the intracranial lesion and the design of the preoperative incision. The present invention has the characteristics of safety, simple operation, high precision, etc., is suitable for the preoperative positioning needs of neurosurgeons at all levels, has strong practicability, and is worthy of popularization.

Description

Technical field [0001] The present invention belongs to the medical equipment industry, and is suitable for preoperative cranial surface positioning of supratentorial lesions such as spontaneous cerebral hemorrhage, traumatic intracranial hematoma and intracranial tumors in clinical neurosurgery. It is used to determine the location and scope of the lesion and is beneficial to determine The best surgical path and surgical incision greatly improve the accuracy and reliability of the operation, avoid the error between the incision and the lesion site during craniotomy, and reduce iatrogenic injury. Background technique [0002] Precise three-dimensional positioning of intracranial lesions has always been a surgical requirement and challenge faced by neurosurgeons. Although CT or MRI has been widely used in hospitals of all sizes at present, although conventional CT or MRI scans show intracranial lesions, they provide the shape, size and anatomical position on the two-dimensional im...
