Abstract

The utility model discloses a forced recovering apparatus for injured finer tendons after operation, which is composed of a back-palm board (1), a tie belt (2) at palm center and a tie belt at the wrist (3). The utility model is characterized in that a micro low-speed motor (5) is fixed on the back end of the back-palm board (1); a drive screw rod of the drive shaft of the micro low-speed motor (5) is meshed with a rotational gear (7); five long half-shaft adjustable cams (9) are arranged on the shaft of the rotational gear (7); each of the long half-shaft adjustable cam (9) corresponds to a pull line (10) with a fingertip sleeve (10), and pull-line-threading rings (12) are all arranged on the positions corresponding to the five finger roots. The utility model is standard in operation and saves time and labor. The pull force pulls along the axial direction of the fingers, which can avoid skew pulling force and keep upright exercise. The upright exercise angle can be gradually increased to meet the exercising requirement of the injured fingers.

Description

Finger tendon injury postoperative is forced convalescence device

Technical field

This utility model relates to a kind of finger tendon postoperative medical auxiliary apparatus, and particularly a kind of finger tendon injury postoperative is forced convalescence device.

Background technology

Therefore people's hands is important activity, work organ, also is the easiest injured position, so, damaging the spleen and stomach outside, the shared ratio of hands surgical operation is the highest.In the patient of hand wound, tendon injury or account for the overwhelming majority with the patient of tendon injury, the treatment to tendon injury is exactly the prosthesis that coincide clinically.Generally, did the prosthesis that coincide after, the adhesion of tendon anastomosis position and surrounding tissue often appears, adhesion of tendon must influence the tendon activity, thereby has a strong impact on the activity of bending and stretching of finger.At present, the method for adhesion of tendon after preventing to perform the operation: the one, scald, promote blood fortune, diminish inflammation with Chinese medicine; The 2nd, pull the art finger ends with hands, it is stretched, when pulling, should strengthen gradually and pull angle, the amplitude of pulling of beginning is controlled to be about 2 degree, strengthens 5 degree every day, and expanding to progressively pulled the postoperative finger straight, after one week, can take exercise voluntarily, thisly pull the weak point that art refers to short its method of rehabilitation with hands and be: operating force is not easy to grasp, and effect is relatively poor, if by the patient from line operate, often do not reach the degree of stretching, extension,, waste time and energy again if assist by medical personnel because of pain, operate also lack of standardizationly, influence the functional rehabilitation exercise effect.In addition, everyly use manually-operated, all can not pull a plurality of fingers simultaneously.At present, the employing easy device that also has, comprise supporting plate, frenulum, the finger-like air cushion, rubber band constitutes, with the wrist portion of frenulum with the patient, palmar hand is fixed on the supporting plate, the finger-like air cushion is established at back at finger, rubber band one end is fixed on the finger tip of finger-like air cushion, the other end is fixed on the palm back of supporting plate, by to the inflation of finger-like air cushion, makes the rubber band pulling suffer from the end that refers to, this device, though to certain effect of having bent and stretched of postoperative finger, and can work simultaneously, refer to that the direction of stretching can not remain on the axis of finger to a plurality of fingers, be unfavorable for that finger bends and stretches to nature position direction, also influences the functional rehabilitation exercise effect.

Summary of the invention

The purpose of this utility model is to provide a kind of postoperative finger that can make to bend and stretch exercise by force, can accurately control again and correct bend and stretch direction and bend and stretch angle, and easy to operate, standard, the finger tendon injury postoperative that can improve postoperative finger function reconditioning effect are forced convalescence device.

For reaching above purpose, the technical scheme that this utility model adopted is: this finger tendon injury postoperative is forced convalescence device, by palm back board, place, centre of the palm frenulum, wrist place frenulum constitutes, place, centre of the palm frenulum is bonded and fixed at the front end of palm back board, wrist place frenulum is bonded and fixed at the middle part of palm back board, all establishing Buddhist nun's floss in the end of centre of the palm place's frenulum and wrist place frenulum buckles, palm back board is fixed on the back of postoperative palm by centre of the palm place's frenulum and wrist place frenulum, it is characterized in that fixing miniature low-speed motor in the rear end of palm back board, on the driving shaft of miniature low-speed motor, connect drive screw, the screw thread of drive screw and transmitting gear engagement, by the promotion of drive screw to transmitting gear, transmitting gear is rotated, a left side that is vertically fixed on the palm back board is inserted at the axle two ends of transmitting gear respectively, in the hole of right gripper shoe, on the axle of transmitting gear, establish five major semiaxis adjustable type cams, the corresponding backguy of each major semiaxis adjustable type cam, rotation by the major semiaxis adjustable type cam, a pine is drawn in realization backguy one, draw or the adjusting of degree by the major semiaxis radius of pine realizes, fix fingertip in the end of backguy, with five corresponding positions of finger root on all establish backguy and pass ring, every backguy is passed corresponding backguy and is passed ring, backguy is consistent respectively at the axis of five postoperative fingers in drawing process, and it is askew partially that pulling force is not produced.This utility model is also implemented by following measure: described major semiaxis adjustable type cam, establish groove at its periphery, the cover of backguy end is looped around in the groove, along establishing bar hole on the wall of major semiaxis one side groove, in bar hole, establish backguy and prop up sheet, backguy is propped up the middle part of sheet and is established rotating screw bolt, rotating screw bolt is rotated in the screw on the major semiaxis adjustable type cam axle, rotation by rotating screw bolt, the distance of sheet from the axle center propped up in the scalable backguy, thereby regulates the major semiaxis of major semiaxis adjustable type cam; In the inboard of centre of the palm place frenulum fixing on gauze pad, with pad in the centre of the palm, softness and absorbing sweat; Described miniature low-speed motor is that per minute 30 changes, and can connect the 220V power supply, and this kind motor is a prior art, can directly buy on the market; Described palm back board is an arc shape board, and the radian that curves inwardly is consistent with palm inflection radian.When using this utility model, palm back board is fixed on postoperative palm back by centre of the palm place's frenulum and wrist place frenulum, fingertip is enclosed within postoperative finger tip, by tightening screw, wire drawing is adjusted to suitable elasticity, regulate backguy and prop up sheet, the suitable angle of bending and stretching that spurs finger, miniature low-speed motor is connected with the mains, can spur finger and realize bending and stretching, begin to be controlled in the scope of bending and stretching 2 degree, prop up the distance of sheet by regulating backguy from the axle center, strengthen gradually and bend and stretch angle, after 5 days, reach the angle requirement of stretching.

The beneficial effects of the utility model are: compare with the method and apparatus of present use, owing to adopt miniature low-speed motor to drive, thus time saving and energy saving, working specification; Because palm back board be and the corresponding to arc of the back of the hand radian, and added backguy at front end and passed ring, made the axial pulling of pulling force, prevented that pulling force is askew partially, the normotopia exercise of influence finger along finger; Because the pulling length of backguy can be regulated by the major semiaxis adjustable type cam, institute so that point bend and stretch angle and can require to regulate according to postoperative finger training needs.
