Body surface positioning device for neurosurgery

Abstract

The invention discloses a body surface positioning device for neurosurgery. The device comprises an acquisition module, a processing module and a projection module; the acquisition module is used for acquiring a three-dimensional image of a to-be-dissected part; the processing module comprises a processor, a controller and a memorizer, wherein the memorizer is configured to store a medical image; the processor is configured to fit the received three-dimensional image and the medical image, complete fitting if the correlation degree is greater than a set threshold value, otherwise carry out fitting again; and the controller is configured to receive the three-dimensional image and transmit a fitted image signal to the projection module; and the projection module is in signal connection with the processing module, is arranged in the same direction as the acquisition module and is used for projecting the received image signal. According to the device, the acquisition module, the processing module and the projection module are arranged, and the projection module can directly project a line fitted by the processing module to the to-be-dissected part of a patient in proportion so that a doctor can accurately position the dissected part of the patient before surgery, errors generated by dissection through a traditional method are avoided, and the doctor can conveniently design an optimal surgical incision.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a body surface positioning device for neurosurgery. Background technique [0002] Anatomy is a medical and biological term, which refers to the use of special knives and scissors to cut open the human body or animal or plant body. This step of making an incision on the human skin is a common step in surgery. The existing dissection method is mainly that the doctor determines the anatomical position based on his own experience and draws a line mark, and dissects according to the position of the drawn line. However, due to individual differences, in There are errors in actual operation, including measurement errors, line drawing errors, calculation errors, etc., which eventually lead to deviations in anatomical structure body surface marks. Taking the midline of the head as an example, since the size of the left and right brains of people is slightly different, During ...
