Problems solved by technology
Traditional registration tools achieve registration by contacting human tissue, anatomical landmarks, or pre-embedded titanium nails. Traditional registration tools will inevitably make surgical tools come into contact with human tissue or blood, which may cause infection. Registration on the surface of the human body, usually due to body position or surgical tools compressing the skin, resulting in larger registration errors
In addition, traditional registration tools are generally carried out after opening the wound for the patient. The actual surgical wound opening time is longer, which increases the complexity of registration preparation and the difficulty of registration.
Moreover, during the processing, production and operation of traditional registration tools, errors that cannot be predicted by doctors are prone to occur, such as improper installation of infrared reflective balls, errors in tool processing dimensions, and bending of probes under unknown circumstances, etc., which may affect the actual situation.

The invention discloses a wireless surface registration tool based on surgical navigation, comprising: a condenser prism, a PCB control board and a battery; the PCB control board is provided with an infrared sensor, a processing chip, a laser diode and an infrared light-emitting diode, and the PCB control board The above components are electrically connected to each other; the battery is electrically connected to the PCB control board; the infrared sensor is used to receive the external infrared signal, and convert the infrared signal into an electrical signal and transmit it to the processing chip. After receiving the signal, the processing chip turns on the infrared light-emitting diode and Laser diode: The light emitted by the infrared light-emitting diode and the laser diode are aggregated into a light path through the condenser prism and shot to the surface of the human tissue to generate a light spot to match the position of the surface registration collection point. Compared with traditional registration tools, the present invention can simplify the registration work of doctors in performing navigation surgery, reduce the contact between surgical tools and patients, reduce the risk of infection of patients, and can effectively improve registration accuracy.
Description
technical field [0001] The present invention relates to a medical device, in particular to a surgical navigation device, in particular to a wireless surface registration tool based on surgical navigation; in addition, the present invention also relates to a method for realizing the wireless surface registration tool. Background technique [0002] The traditional registration tool for surgical navigation is a purely mechanical surgical tool. The traditional registration tool is usually composed of a probe part, a reflective ball array seat and a reflective ball. When in use, the infrared rays emitted by the navigation camera probe hit the reflective ball of the traditional registration tool, multiple (generally more than three) reflective balls reflect the infrared rays, and the navigation camera probe receives the reflected infrared rays; through the principle of binocular recognition , the navigation camera probe can determine the spatial position and positional relationshi...
