Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments; all other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the first embodiment, as shown in fig. 1 to 4, the limb fixing device for orthopedic clinical operation comprises an extension ring 1, wherein the surface of the extension ring 1 is fixedly connected with a connecting rod 5, one end of the connecting rod 5 is fixedly connected with a fixing ring 4, the surface of the fixing ring 4 is fixedly connected with an extrusion device 3, and a positioning device 2 is fixed in the middle of the extrusion device 3 at the surface position of the fixing ring 4;

the extrusion device 3 comprises a sleeve 31, an upper end of the sleeve 31 is connected with an upper telescopic rod 35 in a sliding manner, the lower end of the upper telescopic rod 35 is fixed with a limiting rod 33, a spring 34 is sleeved on the surface of the limiting rod 33, and a lower end of the limiting rod 33 is connected with a lower telescopic rod 32 in a sliding manner.

In the second embodiment, on the basis of the first embodiment, the positioning device 2 comprises a fixed block 23, a puncture needle 21 is fixed at the rear end of the fixed block 23, and a support plate 22 is slidably connected to the surface of the puncture needle 21;
