Embodiment 1

[0058] like figure 1 and figure 2As shown, the marker positioning device of Embodiment 1 of the present invention includes a tracking assembly 1 and a positioning assembly 2. The tracking assembly 1 includes a reference frame 11 and a tracking frame 12. One end of the tracking frame 12 is connected to the reference frame 11, and the other end of the tracking frame 12 One end is provided with a first tooth portion 121 , the positioning assembly 2 is provided with a second tooth portion 21 , the first tooth portion 121 is engaged with the second tooth portion 21 , and the positioning assembly 2 is connected with the tracking bracket 12 . When the tracking assembly 1 is connected to the positioning assembly 2, it is connected to the positioning assembly 2 through the tracking bracket 12, and the first tooth portion 121 is engaged with the second tooth portion 21, so that the tracking assembly 1 and the positioning assembly 2 are not easily connected after being connected. Loose...

Embodiment 2

[0068] The structure of the marker positioning device of this embodiment is the same as that of Embodiment 1, and will not be repeated, and only the differences will be described. The positioning assembly in this embodiment 2 is different from the positioning assembly in embodiment 1. The positioning assembly includes a first locking shaft and a positioning mechanism. The second tooth part is arranged on the positioning mechanism. The first locking shaft passes through and threads It is connected to the first tooth portion, and the first locking shaft is threadedly connected to the second tooth portion. The positioning assembly in this embodiment 2 omits the structure of the connecting head and the second locking shaft, the second tooth part is directly arranged at the end of the clamp, and the tracking bracket and the clamp are directly connected by the first tooth part and the The second teeth are meshed and connected, and the structure is simple and the operation is conveni...

Abstract

The invention discloses a marker positioning device, which includes a tracking component and a positioning component, the tracking component includes a reference frame and a tracking bracket, one end of the tracking bracket is connected to the reference frame, and the other end of the tracking bracket A first tooth portion is provided, a second tooth portion is provided on the positioning assembly, the first tooth portion meshes with the second tooth portion, and the positioning assembly is connected to the tracking bracket. The marker positioning device of the present invention, through the meshing of the first tooth part and the second tooth part, makes it difficult for the tracking component and the positioning component to loosen after being connected, which greatly improves the motion detection accuracy of the marker positioning device and reduces the operation time. Difficulty, improve surgical accuracy. At the same time, the installation height, direction, and pitch angle of the tracking components can be quickly adjusted to meet the needs of use in complex environments.

Description

technical field [0001] The invention relates to a marker positioning device. Background technique [0002] At present, surgical robots have been applied to joint replacement surgery in China. For example, the patent publication No. CN104083217A discloses a surgical positioning device and method and a robotic surgical system. The device includes a patient tracker and a mechanical arm tracker. The challenge of joint replacement surgery is to determine the relative position between the prosthesis and the bone, and accurately cut the osteotomy to make the prosthesis fit better with the bone; the degree of fit between the prosthesis and the bone and the placement of the prosthesis directly affect the Performance and prosthesis life cycle; during joint replacement surgery, the movement of the patient's limbs or external influences (such as movement of the operating table, unpredictable external force interference, etc.) will have a greater impact on the accuracy of osteotomy and p...
