Noninvasive type real-time surgery positioning and navigating equipment

Abstract

The invention relates to noninvasive type real-time surgery positioning and navigating equipment. The noninvasive type real-time surgery positioning and navigating equipment is characterized by comprising a laser positioning and driving device, a work server, a digital signal shunt device and a display; the laser positioning and driving device is in wireless connection with the work server, and the work server, the digital signal shunt device and the display are electrically connected. Compared with existing surgery positioning and navigating equipment, the noninvasive type real-time surgery positioning and navigating equipment has the advantages that self-calibration is realized with automatic operation; a man-machine interface is clear and is supportive to observation perspective images from multiple perspectives; the equipment is wide in application and applicable to all C-armed machines adopted in liquid crystal displays; the equipment is rapid in positioning during surgeries, namely within 30 seconds, and small in error since the overall error is within 1mm.

Description

technical field [0001] The invention relates to a non-invasive real-time surgical positioning and navigation device. Background technique [0002] Traditional methods of orthopedic surgery have large incisions, heavy bleeding, and great damage to the body during the operation. There is a certain chance of serious complications after the operation, and unsightly skin scars are left behind. These body injuries not caused by the disease itself are collectively called 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. [0003] Minimally invasive treatment is based on the improvement and innovation of surgical methodology, and has the advantages of less trauma, faster recovery, and less pain. However, minimally invasive treatment requires certain equipment support. "In vitro positioning" is one of the key techn...

Problems solved by technology

[0006] We have been researching in the field of "surgical positioning and navigation" for many years, and have applied for a number of patents. The application number is 201210385980.2, which is an invention patent for a surgical positioning and navigation device attached to a C-arm X-ray machine. Although the operation is simple and the positioning is accurate , but because the device contains a mechanical remote-controlled image digitization frame and a simple laser emitting device and the image is only processed linearly, there are at least the following defects: 1. Because some models of C-arm X-ray machines have There is a protective frame, which makes the image digitization frame unable to be installed; 2. The transparent square rod of the image digitization frame has a certain thickness, and there is a certain gap between the square rod and the screen surface, so that the operator must operate directly in front of the cross center of the square rod. The operation is difficult and prone to human errors; 3. The image digitization frame in this invention is a mechanical remote control type, requiring the operator to manually control the image digitization frame through a hand-held remote control, so this invention cannot achieve automatic calibration; 4. The invention The machine calibration of the invention adopts the method of manually obtaining calibration point data, so too many human operation errors are added, resulting in relatively poor accuracy stability of the equipment; 5. The laser emitting device used in this invention is relatively simple, and the laser is directly connected to the laser on the tube

Therefore, the laser emitting device has the double defects that it cannot be replaced separately and cannot guarantee the coaxiality of the outgoing light and the laser tube; Simple linear processing will lead to large calculation errors, which will eventually lead to unsatisfactory execution results of positioning and navigation equipment
