Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, a dynamic hip device for minimally invasive surgery for intertrochanteric fractures. The existing dynamic hip device mainly includes a sliding screw 1, a sliding plate 2 and a compression screw 3. The sliding plate 2 includes a sleeve and a fixed plate , there are some fixing screw holes 4 on the fixing plate, and the sliding screw 1 can pass through the sleeve of the sliding plate 2 to be connected and fixed with the compression screw 3, and generally select different models and sizes according to the different needs of the operation. Such as figure 2 and Figure 4 As shown, the dynamic hip device of the present invention also includes a jig handle 6, a threaded hole 51 on the sliding steel plate 2, and a connecting hole 52 on the jig handle 6, and the jig handle 6 and the sliding steel plate 2 are locked by steps. After snapping ...

Abstract

The invention relates to the field of medical devices, in particular to a dynamic hip device for a femoral intertrochanteric fracture minimally invasive surgery. The dynamic hip device comprises a sliding screw, a sliding steel plate and a compression screw. The sliding steel plate is provided with a sleeve, and the sliding screw penetrates the sleeve to be fixedly connected with the compression screw. The dynamic hip device further comprises a drill jig handle, and the drill jig handle is detachably connected with one end of the sleeve of the sliding steel plate. Compared with the prior art, the dynamic hip device is applied to the femoral intertrochanteric fracture minimally invasive surgery, the operation is simpler and faster, the positioning is accurate, the length of an incision is greatly reduced compared with when an original wide exposure mode is adopted, the soft tissue injury is small, the bleeding is less, the operation speed is quick, and the operation risk is reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a dynamic hip device for minimally invasive surgery on intertrochanteric fractures. Background technique [0002] Intertrochanteric fracture refers to the fracture from the base of the femoral neck to above the level of the lesser trochanter, and is one of the common fractures in the elderly. At present, the commonly used method for the treatment of intertrochanteric fractures is to place a dynamic hip screw (DHS) fixation device. The dynamic hip screw (DHS) is developed from the sliding compression screw, which mainly refers to the Richard screw. Hip compression screw. The nail has dual functions of pressurization and sliding, allowing the proximal comminuted fracture fragments to be compressed, so that the fracture ends can be automatically approached and stabilized, enabling early movement and weight bearing. A dynamic hip screw (DHS) consists of a sliding plate with a sleeve,...
