Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing.

[0017] Such as Figure 1 to Figure 3 As shown, the present invention provides a femoral intramedullary nail opening guide, including a bracket 4 with a long arm and a short arm bracket 1 perpendicular to the bracket. The long arm bracket and the short arm bracket form an L-shaped support structure. Both the long arm support and the short arm support are provided with guide holes, and the guide holes can allow the Kirschner wires to pass through after the guide tube is placed. Wherein the long arm bracket is provided with 5 guide holes for keeping the Kirschner wires perpendicular to the long arm, and the short arm bracket is provided with guide holes for keeping the Kirschner wires perpendicular to the short arm, and the guide holes are located on the same section.

[0018] In order to reduce the contact area between the guide and the tissue and facilitate the operation of...

Abstract

The invention relates to medical devices, and provides a femoral nail opening guider. The guider comprises a long arm supporting bracket and a short arm supporting bracket which is perpendicular to the long arm supporting bracket, guiding holes are formed in the long arm supporting bracket and the short arm supporting bracket, a plurality of guiding holes perpendicular to the long arm supporting bracket are formed in the long arm supporting bracket, a plurality of guiding holes perpendicular to short arms are formed in the short arm supporting bracket, and the guiding holes are located on thesame section. The guider adopts the principle of two points and one line, when a long arm guiding tube is completely pressed against the outer side of the cortex of a femoral shaft, the intersection point of extension lines is located at the center of a femoral marrow cavity, the tip part of the femur trochanter or the pyriform sinus is used as the point of penetration, the structure is simple, the implementation is convenient, and the positioning is fast and accurate.

Description

technical field [0001] The invention relates to a medical device, in particular to an opening guide for a femoral intramedullary nail. Background technique [0002] In the surgical treatment of femoral intertrochanteric fracture, after the fracture reduction is completed, the Kirschner wire at the tip of the trochanter or the pyriform sinus is used for positioning and guidance. During clinical operations, the position and direction of the positioning guide pin are often wrong due to visual deviation and obstruction of limbs. To solve this problem, it is necessary to design a guide that can ensure that the guide Kirschner wire is implanted in the proper position of the proximal femur at one time, thereby avoiding multiple fluoroscopy and saving operation time. Contents of the invention [0003] In order to solve the above defects of difficult guiding and inaccurate positioning, the present invention provides a femoral intramedullary nail opening guide with simple structure...
