Problems solved by technology

However, the shape and structure of the dynamic cross nail is complex, the wound is small but the implantation is difficult, and multiple implantation points need to be set on the femoral neck. It is necessary to provide an implantation tool that is easy to operate, accurate in the selection of implantation points, and does not need to enlarge the wound.

Embodiment Construction

[0027] In this article, "proximal end" refers to the end of the medical device close to the doctor when the doctor is using the medical device; "distal end" refers to the end of the medical device away from the doctor when the doctor is using the medical device; this term is consistent with medical device A customary practice in the industry.

[0028] Such as Figure 8 As shown, the power cross nail 3 includes a main implant nail and a fixed plate, the main implant nail and the fixed plate are arranged at a certain angle, the main implant nail is used to install the power nail to complete implantation and fixation in one direction, and the fixed plate is used The implantation and fixation in the second direction are completed by adding fixation screws, so as to fix the femoral neck from two directions and ensure its structural strength.

[0029] Such as Figure 1-7 An implantation tool for implants for patients with femoral neck fractures is shown, including a first part 1 a...

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to the field of A61B17 / 68, in particular to an implanting tool for an implant for a patient with femoral neck fracture. The implanting tool of the implant for the patient with femoral neck fracture, provided by the invention, comprises a first part and a second part, wherein the first part comprises a first straight part, and the first straight part is provided with an open groove; the first part further comprises an extending part, and the extending part extends from the near end of the first straight part to the reverse side direction of the open groove; an acute angle is formed between the extending part and the first straight part; the second part comprises a second straight part, and the second straight part and the first straight part are arranged in a matched mode through the open groove; and the second part further comprises a hole channel part, the hole channel part is fixedly connected with the near end of the second straight part in a coinciding mode, and the far end is fixedly connected with the second straight part in a separated mode by some distances.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to the field of A61B17 / 68, in particular to an implant tool for patients with femoral neck fractures. Background technique [0002] Femoral neck fracture is a common type of fracture in clinic, and it is mainly caused by low-energy injuries in middle-aged and elderly patients and high-energy injuries in young patients. The Chinese patent with publication number CN211300278U provides a femoral neck fracture angle-stabilized intramedullary fixation device, which uses three hollow nails to fix the fractured femoral neck. The dispersed fixation increases the anti-rotation ability and enhances fracture reduction and healing stability; the Chinese patent with the publication number CN108742807A provides a kind of telescopic structure for femoral neck fracture reduction, the telescopic structure includes: a sleeve and a first screw; the diameter of the first screw is the same as th...
