Problems solved by technology

[0003] In the current femoral surgery, the operator needs to use fingers to probe and determine the nail entry point. However, due to factors such as the depth of the nail entry point and the obstruction of the surrounding soft tissue, the surgical operation is more difficult.

Embodiment Construction

[0011] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0012] like figure 1 , figure 2 As shown, a proximal femur intramedullary nail ring guide according to the present invention includes a retractable ring 1, the ring 1 is composed of an unclosed ring, and one side of the ring 1 is provided with a section of hollow guide tube 2.

[0013] Further, the diameter of the guide hole of the guide tube 2 is 3.5 mm.

[0014] Further, both the ring 1 and the guide tube 2 are made of stainless steel.

[0015] Further, when performing femoral shaft fracture or femoral intertrochanteric fracture operation, the medical staff puts the finger into the ring ring 1 at the surgical incision. Drive the intramedullary nail into the patient's body through the guide hole 3 .

[0016] What has been described above is only the principles and preferred embodiments of the present invention...

Abstract

The invention discloses a proximal femur intramedullary nail ring guide apparatus. The proximal femur intramedullary nail ring guide apparatus comprises a contractile ring, wherein the ring is composed of a section of circular ring which is not closed, and a hollow guide pipe is welded to one side of the ring. The proximal femur intramedullary nail ring guide apparatus is simple in structure; when femoral shaft fracture surgery and femoral intertrochanteric fracture surgery are performed, a medical worker stretches a finger into the ring at a surgical incision and takes out the finger after the device is placed in the surgical incision, an intramedullary nail is hit inwards from the hollow guide pipe, and therefore the aim of rapidly and accurately selecting and positioning the proximal femur inlet point is achieved, workloads of the medical worker are reduced, and the proximal femur intramedullary nail ring guide apparatus is worthy of wide popularization.

Description

technical field [0001] The invention relates to equipment for orthopedic surgery, in particular to a ring guide for intramedullary nails at the proximal end of the femur. Background technique [0002] In recent years, due to the improvement of internal fixation devices, the improvement of surgical techniques and the change of people's concept of fracture treatment, femoral shaft fractures tend to be treated surgically. In addition to considering the location and type of fracture, the degree of soft tissue damage, whether there are combined injuries and the patient's general condition, the surgical treatment of fractures must also be selected according to two principles: first, there must be sufficient strength of internal fixation materials, so that early functional exercise can be performed after fixation without internal fixation equipment breaking and failure before fracture healing; second, minimally invasive fracture fixation methods should be advocated to minimize the ...
