Embodiment Construction

[0031] Further detailed explanation through specific implementation mode below:

[0032] In this embodiment, the orientation words about "front end" and "front" refer to the direction of the dynamic tracking needle toward the bone, and the orientation words about "rear end" and "back" refer to the direction of the dynamic tracking needle away from the bone.

[0033] like figure 1 and figure 2 As shown, a dynamic tracking needle includes a positioning needle and a holding rod. The positioning pin includes a rod-shaped needle body 3 , a spiked portion 31 at the front end of the needle body 3 , and a clamping portion 32 at the rear end of the needle body 3 . The spiked part 31 is composed of three intersecting planes at the front end of the needle body 3, the three planes make the front end of the needle body 3 sharp, so that the front end of the needle body 3 can be easily inserted into the bone.

[0034] In this embodiment, the positioning pin is detachably fixed on the fro...

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a dynamic tracking needle. The needle comprises a positioning needle, a positioning sensor arranged at the front end of the positioning needle and a holding rod used for fixing the positioning needle. The holding rod comprises a shell and two clamping arms capable of being pressed, and the positioning needle comprises a locking clamping groove; the locking clamping groove extends into the shell and is connected with the clamping arm in a buckled mode. According to the scheme, after the positioning needle embedded with the electromagnetic sensor is punctured into the bone, the holding rod and the positioning needle can be detached, only the positioning needle is left on the bone, accurate positioning of the bone is guaranteed, and the burden borne by the bone can be relieved. And the positioning needle is small in size, so that interference in the operation process can be reduced. According to the scheme, the locked limiting protrusion and the locked locking clamping groove can be unlocked by pressing the rear ends of the two clamping arms with one hand, and operation is convenient. Moreover, when the clamping arm is pressed, the direction of the applied pressure is perpendicular to the direction of the axis of the positioning needle, so that the depth of the positioning needle penetrating into the bone is not influenced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a dynamic tracking needle. Background technique [0002] During orthopedic surgery, because the skeleton is composed of many bones, and the position of each bone will change slightly during the operation, the accuracy of the operation is poor, which seriously affects the treatment effect. [0003] Therefore, it is urgent to design a dynamic tracking needle that can accurately locate the bone to ensure the accuracy of the operation. Contents of the invention [0004] In view of the above problems, the present invention provides a dynamic tracking needle. [0005] The scheme of the present invention is as follows: [0006] A dynamic tracking needle comprising: [0007] Positioning pins, bound to bones; [0008] The positioning sensor is arranged at the front end of the positioning pin. [0009] Preferably, it also includes a holding rod for fixing the positioning pin...
