A system for precisely guiding a surgical procedure on a patient

Abstract

The present invention provides a system for precisely guiding a surgical operation on a patient, the system comprising: a three-dimensional digital representation for representing the preoperative geometry of a relevant part of the patient; a three-dimensional digital representation for Represents the intended postoperative geometry of the relevant part of the patient, including any implants or other structures intended to be attached to the patient; a movable electro-optical camera mounted at a known location relative to a surgeon and orientation; a first vehicle, including at least 3 targets, for the camera to take images, the vehicle is used to be installed in a known position and orientation relative to the relevant part of the patient; a second a vehicle comprising at least 3 objects for capturing images by the camera, the vehicle being mounted at a known position and orientation relative to an implant or surgical instrument; a calculator for according to the The imaging result of the camera is used to calculate the relative position between the first vehicle and the second vehicle containing at least three objects, and the camera; and software is built in the calculator for calculating the A digital representation of the patient is displayed in relative projection on a display so that the displayed projection can be matched to the surgeon's actual line of sight to the patient at the time.

Description

technical field [0001] A system for precisely guiding a surgical procedure on a patient Background technique [0002] Although the industry agrees that computer-guided systems may both reduce risk and improve outcomes in many types of surgical procedures, such as total knee or total hip replacements, or spinal fusions. But the use of such calculator-guided systems remains low. [0003] For example, some systems are commercially available that can be used to guide a surgeon in the precise positioning of an implant, such as a hip implant, by simultaneously tracking multiple objects, such as the patient itself, the implant and other instruments. However, to be a practical solution, the guiding device used must not obstruct the work of the surgical team or obscure its view, nor force the surgical team to use unfamiliar working methods to support it. That is, the wound must be clearly visible from the guidance system. In addition, navigation targets, implants and other instrum...

Problems solved by technology

[0017] The use of guiding systems also does not result in significantly prolonging the duration of the surgical procedure, either for economic reasons or to avoid increased infection risks
