Embodiment Construction

[0026] A preferred embodiment will be given below, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.

[0027] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, a two-way self-locking rod of a ball-and-socket positioner includes a support rod 10; a bone nail 20 is connected to the lower end of the support rod;

[0028] The ball joint connector 30 has a through cavity, and the through cavity is provided with a ball 31 , a ball joint limiter 32 , a first elastic member 33 and a locking member 34 arranged in sequence. In this embodiment, the first elastic member 33 is a disc spring.

[0029] The lower opening of the through chamber has a limiting end 35 for preventing the ball from detaching from the ball joint connector. The limit end is distributed in the circumferential direction.

[0030] The locking member 34 is screwed to t...

Abstract

The invention discloses a two-way self-locking rod of a ball-and-socket positioner, which comprises a support rod; a bone nail is connected to the lower end of the support rod; a ball joint connector is arranged on the support rod; There are sequentially distributed spheres, ball joint limiters, first elastic parts and locking pieces in the cavity; the sphere is fixedly connected to the upper end of the support rod; There is a device frame connector; the device frame connector has a receiving hole; the device frame connector is provided with a snap-in pin pierced through the receiving hole; the two ends of the snap-in pin are fixedly connected with a blocking piece and a pressing piece; the pressing piece A second elastic part is arranged between the outer side of the hole wall and the receiving hole; the device holder rod is inserted into the receiving hole, and the locking pin is connected to the device holder rod. The present invention can be fixedly connected to the tracker, and can realize the 360-degree rotation of the tracker, which not only facilitates the operation, but also improves the accuracy of the operation, and can also realize quick connection and quick separation between various components.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bidirectional self-locking rod of a ball-and-socket positioner. Background technique [0002] When using an orthopedic surgical robot to perform orthopedic surgery, it is necessary to set a tracker on the part of the human skeleton to be operated. Through the signal reflected by the tracker, the exact position of the site to be operated can be located, so that the operation can be carried out smoothly. [0003] The currently used tracker is usually fixed on the support rod, the bottom of the support rod is provided with a bone nail, and the bone nail is fixed to the bone. When the strut is fixed to the bone, it cannot be adjusted. If repositioning is required, the pin will need to be removed from the bone and then repositioned in the adjusted position. The existing technology not only brings unnecessary harm to the patient, but also delays the operation time and ...
