Surgical location and navigation device attached to C-arm X ray machine

Abstract

The invention relates to a surgical location and navigation device attached to C-arm X ray machine. The surgical location and navigation device comprises a laser location drive device, a wireless remote controller and an image digitalized frame, wherein the laser location drive device, the wireless remote controller and the image digitalized frame are wirelessly interconnected; the laser location drive device comprises an upper plane motion mechanism, a lower plane motion mechanism, an upper plane marking plate, a lower plane marking plate, a laser emitting device and a drive device control circuit, the upper plane marking plate is parallel with the lower plane marking plate, the upper plane motion mechanism is connected with the upper plane marking plate and the lower plane motion mechanism is connected with the lower plane marking plate. Compared with the prior art, the surgical location and navigation device disclosed by the invention has the advantages that 1. the structural design is reasonable, the location and calibration are convenient and the operation is simple; and 2. the device has good application effect and can automatically, rapidly and accurately locate the foreign matters or pathological tissues within a human body, thus improving surgical safety and accuracy and simultaneously reducing radiation exposure and surgical trauma.

Description

technical field [0001] The invention relates to a surgical positioning and navigation device attached to a C-arm X-ray machine. Background technique [0002] Orthopedic surgery usually has large incisions, heavy bleeding, and great damage to the body during the operation. It may cause serious complications and leave unsightly skin scars after the operation. These body injuries not caused by the disease itself are collectively referred to as iatrogenic injuries. In recent years, the medical community has proposed and begun to actively implement minimally invasive therapy, that is, to achieve the greatest therapeutic effect with the smallest iatrogenic trauma. Minimally invasive treatments are often referred to as percutaneous surgery, or surgery without incisions in the body. To achieve minimally invasive treatment, in addition to traditional orthopedic surgery techniques, a key technology that can achieve "precise positioning of lesions in vitro" is also required.

AI Technical Summary

Problems solved by technology

[0003] In the early days, surgeons used the fluoroscopy of the C-arm X-ray machine during the operation, combined with anatomical knowledge, and placed steel needles and other markers on the skin to locate the lesion in vitro. The operation was very complicated and the error rate was high, which often led to surgical failure. , giving birth to computer-aided surgical positioning and navigation technology, which has been gradually applied clinically. However, this type of technology still has the defects of low precision, high cost, and complicated operation, and cannot be widely used.

[0004] The patent number is 201210023747.X, and the name is an invention patent of an intelligent laser projection positioning device. Although the operation is simple and the positioning is accurate, because the laser positioning device is designed at the transmitter end of the C-arm X-ray machine, there are at least the following defects: 1. .Usually during the operation, the doctor places the transmitter of the C-arm X-ray machine under the operating bed, which can reduce radiation exposure by about 25%. However, in this invention, the transmitter of the C-arm X-ray machine must be placed above the operating table, resulting in Increased radiation damage for patients with traditional Chinese medicine; 2. The shape of the transmitting end of the C-arm X-ray machine is irregular and there are few metal components, so the connection stability between the invention and it is poor; The perspective field of view above the operating table is small, which may cause adverse interference during the operation; 4. Due to the limited space of the equipment, image tracking and other modules cannot be placed to further improve accuracy and safety
