Surgical navigation system employing wireless face registration and face registration signal acquisition method

Abstract

The invention discloses a surgical navigation system employing wireless face registration and a face registration signal acquisition method. The surgical navigation system comprises a computer, a display, a navigation camera probe, a converter and a wireless face registration tool. The computer is electrically connected with the display. The navigation camera probe is electrically connected with the converter which is electrically connected with the computer. The wireless face registration tool is provided with an infrared sensor and an infrared transmitting end. The infrared sensor is used for receiving an infrared signal of the navigation camera probe and then triggering the infrared transmitting end to transmit infrared to the surface of a part requiring face registration. The navigation camera probe is used for acquiring an infrared signal of the surface of the part requiring face registration and transmitting the infrared signal to the computer through the converter; the computer processes the infrared signal and registers a processing result and an original model. The display is used for displaying a registration result. The surgical navigation system and the face registration signal acquisition method have the advantages that registration work before a navigated surgery can be simplified, contact of surgical tools with a patient is reduced, the risk that the patient is infected is decreased, and time for opening an actual wound of the patient is shortened.

Description

technical field [0001] The invention relates to a medical device, in particular to an operation navigation system using wireless surface registration. In addition, the invention also relates to a surface registration signal acquisition method of a surgical navigation system using wireless surface registration. Background technique [0002] The existing surgical computer-aided navigation system is a three-dimensional positioning operation support system. During the operation, computer technology is used to unify the patient's image data before or during the operation (from CT computed tomography, MRI magnetic resonance imaging, etc.), the patient's lesion position during the actual operation, and the coordinate system where the surgical tools are located. . Usually, the image data in the computer is unified with the coordinates of the actual patient's human tissue, and registration is achieved by contacting human tissue, anatomical landmarks, or pre-embedded titanium nails....

AI Technical Summary

Problems solved by technology

The usual point registration method will inevitably make the surgical tool contact with human tissue or blood, which may cause infection. If it is only registered on the surface of the human body, the registration error will become larger due to the pressure of the body position or the surgical tool on the skin.

In addition, the traditional point registration method is generally carried out after the wound is opened for the patient. The actual surgical wound opening time is longer, which increases the complexity of registration preparation and the difficulty of registration.
