A guiding and holding device for upper limb functional exercise

Abstract

The invention discloses an upper limb functional exercise guiding and maintaining device. The device comprises a base and a rectangular plate, a support arm is fixed on the lower side of the rectangular plate, a curved block at the right end of the support arm is inserted into an arc groove of a semicircular plate, and one end of the semicircular plate is fixedly provided with a guiding rod; a teeth section is formed in one end of the inner arc wall of the semicircular plate; the support arm is sleeved with a rectangular column, and the rectangular column is fixed with a rectangular strip plate, the right end of the rectangular strip plate faces gear teeth of the teeth section, the front end of the rectangular column is fixedly provided with a rectangular driving plate, and the rectangulardriving plate can drive the rectangular column to move. A crossbar of the device can guide movement tracks of injured persons with fractures in the straightening and bending function exercises of arms, and effectively prevent the arms from deviating, and the semicircular plate can be fixed at a certain angle by the cooperation of the teeth section and the tapered portion of the rectangular stripplate, thereby keeping the fractured arms at a certain angle for a period of time.

Description

[0001] Technical field: [0002] The invention relates to the technical field of medical equipment, in particular to an upper limb functional exercise guiding and holding device. [0003] Background technique: [0004] Olecranon fractures are common fractures of the elbow. In most cases, fractures involve meniscal notches and are intra-articular fractures. Generally, the wounded are treated with Kirschner wire tension band internal fixation medical treatment. After the operation, the arm needs to be bent and straightened. During the exercise, the arm is bent or straightened due to the pain of the arm or the guiding effect of the internal fixation. At the time, you cannot exercise according to the normal arm bending and straightening trajectory. Often the arm will be deflected to the outside when straightened. When the arm is bent, the arm will be deflected to the inside. This will affect the recovery of the normal function of the arm. In place, you need a little improvement every da...

AI Technical Summary

Problems solved by technology

Generally, Kirschner wire tension band internal fixation is performed on the wounded. After the operation, the arm needs to be bent, straightened and other functional exercises. When you do this, you can't exercise according to the normal trajectory of arm bending and straightening. When straightening, the arm will tend to lean to the outside. When bending, the arm will lean to the inside. If this continues, it will affect the recovery of normal arm functions. In place, you need to make a little progress every day, and increase the bending angle a little every day. When you need to keep at a certain angle for a certain period of time, due to the lack of strength in your arms, you can't keep it for a long time, and others will help and it will take up a lot of time for others, affecting the normal work of others. and rest
