Abstract

The invention provides a minimally invasive surgical positioning system. An endoscope is used for monitoring a surgical region; a marking positioning structure includes an A group calibration member and a positioning needle portion which have a fixed relative position relation; the positioning needle portion is used for entering the surgical region, and selecting a surgical part under the monitoring action of the endoscope; the A group calibration member is positioned outside a human body; a B group calibration member is fixed on a surgical mechanical arm; a three-dimensional space positioningdevice is used for acquiring spatial positions of the A group calibration member and the B group calibration member, and forming a three-dimensional relative position relation between the A group calibration member and the B group calibration member; and the control device is used for determining a three-dimensional relative relation between the surgical part selected by the positioning needle portion and the B group calibration member according to the three-dimensional relative position relation between the A group calibration member and the B group calibration member and the relative position relation between the A group calibration member and the positioning needle portion, and accordingly controlling the surgical mechanical arm to move to the surgical part. The minimally invasive surgical positioning system is accurate in positioning.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a positioning system for minimally invasive surgery. Background technique [0002] Endoscopes have been widely used in various minimally invasive operations, such as arthroscopy for joint repair in sports medicine, transforaminal surgery for spine surgery, laparoscopy for resection and repair of various abdominal internal organs, etc. Compared with open surgery, minimally invasive surgery requires smaller incisions, less peripheral trauma, and faster recovery. [0003] In the usual minimally invasive surgery, under the monitoring effect of the endoscope, the doctor holds the surgical tool and directly performs the operation under the microscope. However, the field of view under the microscope is limited, the operation of surgical instruments is limited, it is difficult to find the surgical site accurately, and there is a long learning curve, especially when the surgical ...
