Embodiment Construction

[0027] see figure 1 , 2 As shown: the present invention is a central clamp for installing a femoral neck protection device. The central clamp is provided with a fixing base 10, and the fixing base 10 is provided with a fitting part 11. In this embodiment, the fitting The part 11 is a funnel-shaped hollow cylinder, and the inwardly condensed end of the fitting part 11 is connected with an extension part 12 which is hollow inside. In this embodiment, the extension part is a hollow rod body, and the extension A thread 121 is provided on the surface of the part 12, and a fan part 13 is provided at the end of the extension part 12 that is not connected with the sleeve part 11, and a guide piece 20 that is hollow inside is inserted in the extension part 12. In this embodiment The guide is a hollow tube, and one end of the guide 20 is provided with a flange 21 with an inner diameter larger than the inner diameter of the extension 12, so that when the guide 20 is inserted in the exte...

Abstract

A central holder for installing the protector for femur neck is composed of a fixing base, a hollow sleeving part on said fixing base, a hollow extending part integrated with said hollow sleeving part, a holding part which is connected to said fixing base in movable mode, and an arc connecting rod with one end linked to one end of said holding part and another end with a push needle in contact with the projected position of femur.

Description

technical field [0001] The invention relates to a central clamp for installing a femoral neck protection device, in particular to a device capable of drilling a positioning pin into a designated position of a damaged femur, thereby shortening operation time and reducing pain of a patient. Background technique [0002] At present, for the joint method of the fractured femoral neck, generally the fractured part is cut and sawed flat, then covered with a plate-shaped steel material, and then two nail bodies are driven into the femur to fix it. However, in the existing surgical devices, in addition to the disadvantages of unstable fixation and coating, the newly grown blood vessels and calluses cannot effectively cover the steel, so that the plate-shaped steel cannot be completely integrated with the femur and is subject to damage. Protection, and then the broken femur and the coated steel have limited strength and are easy to separate. The practicability is greatly reduced, an...
