A kind of brain spreader and preparation method thereof

Abstract

The invention provides a brain distracter and a manufacturing method thereof. The brain distracter comprises a distracter body and a fixing device. The distracter body comprises a distraction piece and an adjusting disc arranged on the outer side of the distraction piece in a sleeving mode. The fixing device comprises a connecting block, a connecting rod and a connecting clamp. The connecting block is connected with an outer cylindrical surface of the distraction piece. The connecting block is rotationally connected with one end of the connecting rod through a first rotating shaft. The axis of the first rotating shaft is perpendicular to the axis of the distraction piece. The other end of the connecting rod is rotationally connected with the connecting clamp through a second rotating shaft. The axis of the second rotating shaft is parallel to the axis of the distraction piece. The connecting clamp comprises an upper clamping plate, a lower clamping plate and a screw. The upper clamping plate is provided with a threaded hole which in screw connection with a screw. The lower end of the screw is fixedly connected with a pressing head. According to the brain distracter, the angle of the distracter body around the Y axis can be adjusted inside an X-Z plane, the angle of the distracter body around the Z axis can be adjusted inside an X-Y plane, and the length of the connecting rod is adjusted; a doctor can select a proper skull to be clamped, the brain distractor is firmly fixed, and operation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a brain spreader and a preparation method thereof. Background technique [0002] Due to the deep location and complex structure of deep brain and intraventricular tumors or vascular lesions, there are clinical surgical approaches such as transcorticostomy approach, transcorpus callosum-interfornix approach, and triangular approach to reach the lesion area during surgery. At present, the field of brain surgery and neurosurgery recognizes that the surgery in this area is complicated, the operation process is difficult, the hemostasis in the operation area is difficult, and the total resection rate is not high. [0003] During deep brain and intraventricular surgery, it is necessary to create a fistula from the cerebral cortex, and then the brain tissue must be retracted and fixed before performing targeted operations on the deep part. The process of exposing th...

AI Technical Summary

Problems solved by technology

However, during the operation, the spreader and the skull are required to be relatively fixed. If the automatic retractor base is used, the automatic retractor base still needs to be fixedly connected with the skull through a fixing device, so the utility model has not completely solved the fixation of the spreader. problem, and the above mentioned retractors are not equipped with cleaning, suction, lighting and other devices. Active bleeding will inevitably occur during the operation. If not cleaned in time, the operation field will be unclear and affect the effect of the operation.
