Abstract

The utility model relates to a bone marrow fixing nail medical instrument, comprising a lifting shaft, an upper clamping block, a lower clamping block, a screw-controlling corner rod, a positioning block and screw nail elements. The front end of the lifting shaft is provided with a circular disk whose horizontal circle diameter surface is used for the locking of the upper and the lower clamping blocks, so a pivot-joint rotation structure which makes the backswing movement with two directions and forms a pivot point for an elbow joint is formed. The upper surface and the lower surface of the upper and the lower two clamping blocks are provided relatively with groove circles with concave radiuses and constitute a volume circular groove chamber whose interior is coated with a sphere excircle diameter surface of the screw-controlling corner rod. Therefore, the rotation and the slide of the screw-controlling corner rod can be controlled and the screw-controlling corner rod can form the angle and the distance with any orientations. Consequently, a barrel tube of the screw-controlling corner rod can be calibrated and implanted in an angle hole which is preset through a bone marrow internal rod. The utility model has convenient angle adjustment and operation.

Description

Bone marrow is followed closely medical device admittedly

This utility model relates to the physical therapy appliance in a kind of medical hygiene field, particularly relates to a kind of bone marrow and follows closely medical device admittedly.

In general traffic accident accident, come to harm and cause femur, fractureing of tibia occupies high ratio, the treatment of these injuries must be integrated fracture with integer medical treatment device in advance and recover fixing, to reach the purpose that helps the long-term treatment recovery from illness, and its structural grouping element of this kind integer medical treatment device is many, complex structure and operation inconvenience, when being driven in the bone marrow, staple is loosening easily, and the screw piece of locating piece outer end directly peaks at act bar portion and urges locking, often cause and to calibrate the staple hole that is implanted in the bone, it has great error, and under urging for a long time, often cause many fixed point concave surfaces, screw is slipped, to cause it to decide to hole under the angular error and produce and depart from getting, secondary injury such as often cause making that patient's bone skin ulcer hole suffers to destroy once more.

This utility model designer is because its structure of traditional integer medical treatment device has defective, and be further improved, promote it to have more the practical function of medical treatment, satisfy with abundant medical science experience and Professional knowledge, after repeatedly designing repeatedly, manufacture experimently and improving, create this utility model that has more Practical Benefit finally.
