Problems solved by technology

This device is placed on the side of the affected limb for surgery through a straight-rod guide device, which requires a long length of guide pin and high cost
And due to the size limitation between the X-ray light source and the X-ray imaging device at both ends of the C-arm of the orthopedic robot, it is impossible to use the C-arm

Example Embodiment

[0037] The present invention will be described below in conjunction with the drawings.

[0038] The present invention relates to a guide pin locator for an orthopedic robot, and its preferred structure is as figure 1 As shown, a curved guide positioning device is included. The curved guide positioning device includes a connecting rod 1 and a bracket 2 connected to each other. The connecting rod 1 is provided with a sliding sleeve 3 that can slide along the axis of the connecting rod. A fixing sleeve 4 is also provided. The fixing sleeve 4 is fixed on the connecting rod 1 and cannot slide along the axis of the connecting rod 1. A sleeve fixing structure is provided on the bracket 2 for fixing and installing the guide sleeve 9. The guide pin 10 is inserted into the guide sleeve 9 to guide the guide pin 10. The angle between the axis of the guide sleeve 9 and the axis of the connecting rod 1 is between 15 degrees and 75 degrees after the guide sleeve 9 is installed on the guide pin l...

Abstract

The invention relates to an orthopaedic robot guide needle positioner, a navigation unit and a positioning system. The orthopaedic robot guide needle positioner comprises a curved guide positioning device. The curved guide positioning device comprises a connecting rod and a support which are mutually connected, a sliding sleeve capable of sliding along the axis of the connecting rod is arranged on the connecting rod, a sleeve fixing structure is arranged on the support, a guide sleeve used for guiding a guide needle is fixedly disposed through the sleeve fixing structure, and the axis of the guide sleeve forms an angle ranging from 15 to 75 degrees with the axis of the connecting rod after the guide sleeve is disposed. By the arrangement of the curved guide positioning device, the guide needle for cooperation can be greatly shortened and is enabled to be far away from a mechanical arm of an orthopaedic robot, interference of the C-shaped arm and the guide needle is removed, and requirements on operation can be well met.

Description

technical field [0001] The invention relates to a medical device, in particular to an orthopedic robot guide pin positioner, a robot navigation device and a positioning system for minimally invasive orthopedic surgery. Background technique [0002] With the continuous improvement and improvement of trauma orthopedics treatment technology, minimally invasive orthopedics surgery has become the main direction of the development of trauma orthopedics. Due to the closed reduction and minimally invasive fixation of this new surgical method, a lot of work needs to be exposed to X-rays. The large amount of X-rays radiated during the operation can easily pose a serious threat to the health of patients and surgeons. Even harm, especially for surgeons, long-term X-ray radiation can cause a series of health problems such as low immunity. At present, many countries in the world are committed to developing various new navigation technologies to improve the accuracy of minimally invasive ...
