Embodiment Construction
[0035] In the following, the present invention will be more clearly and completely described by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the described embodiments.
[0036] like Figure 1 to Figure 4 As shown, this embodiment provides a marker nail for osteotomy. The marker nail is used as a temporary reference mark point during osteotomy. The marker nail provided by this embodiment includes a bolt head 10 and a bolt body connected to each other. 20. The bolt body 20 is screwed into the bone, the bolt head 10 is fixed relative to the bone, the bolt head 10 is provided with a marking part 101, and the position of the reference mark point is determined by touching the bottom of the marking part 101 with a probe.
[0037] Wherein, by setting the marking part on the bolt head 10 of the marking nail, the probe in the surgical robot navigation system can determine the position of the marking part by to...

The invention discloses a marking nail for osteotomy. The marking nail is used as a temporary reference marking point during osteotomy; the marking nail provided by the embodiment comprises a bolt head, a calibration part is arranged on the bolt head, and the position of the reference marking point is determined by touching the bottom of the calibration part through a probe. The calibration part is arranged on the bolt head of the marking nail, so that the probe in a surgical robot navigation system can determine the position of the calibration part by touching the bottom of the marking part, and the calibration part is used as the reference marking point. In this way, the probe can mark the reference marking point more easily, and meanwhile the calibration precision of the probe is improved. A counter bore is arranged at the top of a meter, so that the side wall of the counter bore plays a guiding role when the probe is in point contact, point contact of the probe is facilitated, and the calibration precision can be improved at the same time. The calibration part is arranged to be a spherical surface, so that the probe can extend into the calibration part from multiple angles and is in point contact with the bottom of the calibration part from multiple angles, and the convenience of probe detection is improved.
Description
technical field [0001] The invention relates to a marking nail for osteotomy. Background technique [0002] Joint osteotomy is usually used for the surgical treatment of joint injuries. Traditional canal osteotomy is usually done manually by doctors and mainly depends on clinical experience and judgment. With the advancement of science and technology, surgical robot navigation can be used to assist the doctor's clinical experience to complete the joint osteotomy. Compared with traditional surgery, the accuracy of surgery has been greatly improved, and the operation time has been greatly shortened, reducing the physical exertion of doctors during surgery. [0003] To assist surgery through surgical robot navigation, it is necessary to establish a connection between the central control, the robotic arm, the end effector, and the bone joints. In the process of surgical robot navigation to assist the operation, it is necessary to mark the nails so that the optical measurement ...
