Technical Field

The invention belongs to the technical field of medical rehabilitation instruments, and particularly relates to a shoulder arthroscopy postoperative exerciser.

Background

Shoulder arthroscopy is a diagnosis and treatment scheme for shoulder joint diseases which is commonly used clinically at present. Such as the free body of the joint, the free body is definitely diagnosed and removed; the shoulder joint is unstable, the injury parts of the rotator cuff, the joint capsule and the labrum can be determined through shoulder arthroscopy operation, and the repair operation can be carried out; the rupture degree of the biceps brachii muscle can be known, and the broken end is cut off to relieve pain; the osteoarthritis can be debrided and washed under a shoulder arthroscope; the shoulder suppurative arthritis can be cleaned and washed under the shoulder arthroscope; acromion percussion syndrome, which can be used for acromioscopic examination and acromiotomy.

With the continuous development of sports medicine, shoulder arthroscopy operations are commonly carried out in various hospitals in China, but at present, one of the main problems troubling the sports medicine is the healing of broken ends, particularly the healing of growth after the rotator cuff is broken, and the shoulder arthroscopy operations become a worldwide research hotspot. Because long-term fixation leads to stiffness of shoulder joints, later shoulder movement and function are severely limited, but improper movement and early movement can cause the sewn rotator cuff to be torn again and lose the function of the sewn rotator cuff to be broken. Therefore, in the early stages of rehabilitation, especially over the period of 0-4 weeks, there is a need for restorative exercise of the patient's shoulder joints. At present, large comprehensive rehabilitation equipment has good exercise effect but is difficult to popularize; the simple apparatus cannot quantify the exercise amount, and the rotator cuff is easily injured again.

As shown in fig. 4, a locking slot 311 is formed at an end of the gear shaft 310; referring to fig. 3, a single arm rotation guide groove 430 is fixedly connected to the pressing plate 320 at one side of the arm attaching rod 410; a limit concave ring 421 matched with the single-arm rotation guide groove 430 is formed on the side wall of the gear shaft transmission sleeve 420 so as to be in sliding connection with the single-arm rotation guide groove 430; a transmission spring button 440 is arranged on the gear shaft transmission sleeve 420; the protruding end of the transmission spring button 440 is provided with a clamping platform 441 matched with the clamping groove 311, and the transmission spring button 440 is suitable for popping out and clamping into the clamping groove 311 when pressed down to lock the gear shaft transmission sleeve 420 and the gear shaft 310. In this embodiment, the single-arm rotation guide groove 430 is fixedly connected to the pressing plate 320 by a connecting rod; through the arrangement of the transmission spring button 440, the arm attaching rod 410 can be separated from and coupled to the gear shaft 310. In the earliest period after operation, such as the first week, the transmission spring buttons 440 on both sides can be pressed down, so that the two pairs of arm attaching rods 410 and the gear shaft 310 are both in a transmission state, at this time, one hand which is not operated or is driven by other people to perform early recovery rotation exercise can be driven by one hand which is operated, at this time, the one hand which is operated is passively rotated, active force application is not needed, and the operation part is not easy to tear again; with the healing of the operation part, the transmission spring button 440 of one hand side which is not operated can be loosened to the middle period of the operation, such as the second and third weeks, so that the arm attaching rod 410 of the side is separated from the gear shaft 310, the arm attaching rod 410 of the side only plays a role of fixing with the wrist at the moment, the gear shaft 310 of the side can freely rotate, namely, one hand which is operated can actively rotate at the moment to perform the recovery exercise of active force application, and meanwhile, the rotation range can still be controlled by the rack adjusting spring button 510.

As shown in fig. 3 and 4, the one-arm rotation guide groove 430 includes: a main guide groove 431 fixedly connected to the pressing plate 320 on one side of the arm attaching rod 410; two sub guide grooves 432 movably connected to both sides of the main guide groove 431 and adapted to be extended with respect to the main guide groove 431; a guide groove fastening member 433 provided at an overlapping portion of the main guide groove 431 and the two sub guide grooves 432, adapted to fix the main guide groove 431 and the two sub guide grooves 432 after adjusting the extension length of the sub guide grooves 432; the main guide groove 431 and the sub guide groove 432 have the same groove width so that the gear shaft transmission sleeve 420 slides in the main guide groove 431 and the sub guide groove 432. At the later stage of operation, such as the fourth period, the driving spring button 440 of one hand side for performing the operation can be released, at this time, the gear shaft driving sleeve 420 of the side is separated from the gear shaft 310 of the side, the gear shaft driving sleeve 420 can rotate back and forth in the main guiding groove 431 and the auxiliary guiding groove 432, that is, one hand for performing the operation can perform active rotation larger than the aforementioned range, and because the active rotation at this time can not drive the rack 200 to slide, the exerciser itself can not be overlong to have a larger inclination range of the holding assembly 400, and the usability of the product is ensured.

In conclusion, the shoulder arthroscopy postoperative exerciser provided by the invention has the advantages that the two holding components can synchronously rotate by arranging the rack and the gear component, one hand which is not operated or is driven by other people to perform operation can perform early recovery rotation exercise in practical use, the sliding range of the rack can be adjusted by the rack adjusting component, so that the inclined range of the holding components is controlled, the rotating angle of the arm is controllable, the recovery exercise can be quantified by combining the rotating times on the basis, and the sewn rotator cuff can be prevented from being torn again due to improper exercise.
