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.

The invention discloses a surgical navigation system and a signal acquisition method using wireless surface registration, including a computer, a display, a navigation camera probe, a converter, and a wireless surface registration tool; the computer is electrically connected to the display, and the navigation camera probe is electrically connected and converted The converter is electrically connected to the computer; the wireless surface registration tool is equipped with an infrared sensor and an infrared transmitter, and the infrared sensor triggers the infrared transmitter to emit infrared rays to the surface registration required after receiving the infrared signal emitted by the navigation camera probe. The surface of the part; the navigation camera probe collects the infrared signal on the surface of the part to be registered, and transmits the signal to the computer through the converter. The computer processes the signal and registers the processing result with the original model, and displays the registration situation through the display. The invention can simplify the registration work before the navigation operation, reduce the contact between the operation tool and the patient, reduce the infection risk of the patient, and reduce the actual wound opening time of the patient.
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....
