At present, the medical devices of positioning and guiding is more single when being used for fracture such as femoral head, femoral intertrochanteric, pelvis, dentoid process of axis, normally used is the neck of femur guider, this fixed guider mostly is one-dimentional structure, it is at most two-dimensional structure, it exists the positioning and guiding inaccuracy, does not conform with shortcomings such as dissection, and its internal fixation effect can not reach gratifying degree.
Technology contents
The purpose of this utility model is in order to solve above-mentioned the deficiencies in the prior art part, provides a kind of and can reach better positioning effect by the three-dimensional localization mode, selects flexibly, and positioning and guiding is the three-dimensional localization guider accurately.
For achieving the goal, this utility model provides following technical solution:
A kind of three-dimensional localization guider, comprise end seat, platform, it is characterized in that it is template that the described end is sat, the plate face is provided with locating hole, and sit with platform and flexibly connects at the end, is equipped with the cylinder guider on the platform, this cylinder guider is axially arranged with penetrating pilot hole, the cylinder body surface is provided with the hole, and a tee T body surface is decided guide pipe synchronously and placed on the hole, and end seat, platform are fixed by a fixture.
Feature of the present utility model also be the hole on the described cylinder be arranged on cylinder and platform contact surface reach side direction dorsad, two holes become vertical angle.
Feature of the present utility model is that also cylinder and contact with platform face are planar structure.
Feature of the present utility model is that also platform is provided with a hole, and cylindrical contact plane is provided with a projection, and projection is embedded in the hole on the platform.
Feature of the present utility model is that also the cylinder pilot hole is located at cylinder axis to the center, and coaxially around the hole also is provided with three penetrating pilot holes in addition, and three holes become equilateral triangle.Like this, as required, can conveniently select the nail type, squeeze into interior nail by different pilot holes.
Feature of the present utility model also is to take the end of at and also is provided with one handle.
