Technical Field

The invention relates to the technical field of orthopedic rehabilitation tools, in particular to a multifunctional crutch for orthopedic rehabilitation.

Background

Orthopedics is one of the most common departments in all hospitals, and mainly studies the anatomy, physiology and pathology of the skeletal muscle system, and maintains and develops the normal form and function of the system by using medicines, operations and physical methods.

With the change of times and society, the spectrum of orthopedic injuries has changed obviously, for example, the diseases such as osteoarticular tuberculosis, osteomyelitis, poliomyelitis and the like are reduced obviously, the injuries caused by traffic accidents are increased obviously, the population is aged, the fracture and osteoscientific arthropathy caused by senile osteoporosis are increased, the influence of environmental factors is increased, bone tumors and rheumatoid arthritis are increased correspondingly, and the like.

In the process of orthopedic treatment, orthopedic rehabilitation is an important step, and a series of limb dysfunction such as joint mobility disorder, muscle strength decline, activity pain and the like are avoided.

The orthopedic rehabilitation is mainly used for patients with limb movement dysfunction caused by injuries of movement systems such as bones, muscles, tendons, joints, ligaments and articular cartilages. These patients often suffer from disuse muscular atrophy, scar adhesion, fibrous tissue contracture, muscle strength decline, limited joint mobility, osteoporosis, osteoarthritis, pressure sores, thrombosis, pain, gait abnormalities, low ability to self-care.

The orthopedic rehabilitation aims to reduce and prevent complications, relieve pain, increase muscle strength, improve joint mobility and gait, improve daily life capacity and improve life quality of patients.

For an orthopedic rehabilitation subject, in the early rehabilitation process, the self-activity is realized by gradually separating from external assistance; the external assistance here mainly refers to the accompanying of the medical care workers. Therefore, for the patient with leg inconvenience, it is a common approach to use a crutch or other tools.

However, the existing walking stick works more singly, has low flexibility and has certain improvement space.

Therefore, the inventor designs the multifunctional crutch for orthopedic rehabilitation to solve the problems.

the driving gear 603 is also symmetrically arranged on the handle shaft 105 and is positioned between the two main frame rods 103; a vertical rack 602 is meshed at the front side of the driving gear 603; the rack 602 passes through the lifting plate 402 and the main body frame downwards, and the bottom end of the rack is hinged with the top end of a first-class push-pull rod 604; the left side and the right side of the seat plate 108 are connected with a mounting shaft 605, and the mounting shaft 605 is close to the rear end of the seat plate 108; the bottom end of a push-pull rod 604 is hinged with the seat plate 108 through a mounting shaft 605; a limiting rope 601 is connected between the top end of the rack 602 and the main body frame.

The following describes the use method of the crutch by taking the embodiment as an example:

this support of walking stick holds in palm 104 height-adjustable, specifically, rotate axle 201 No. one through adjustment hand wheel 202, based on the screw thread effect, make two removal nuts 203 be close to each other or keep away from to drive support through crossbar 204 and hold in the palm 104 and remove for main hack lever 103, realize height-adjusting, and utilize the screw thread auto-lock to realize the location.

The crutch can also rotate through the handle shaft 105 to enable the push-pull assembly 6 to drive the seat plate 108 to be folded or put down, so that the function switching of the seat is realized;

specifically, the second shaft 302 drives the worm 303 to rotate through the second adjusting handwheel 304, and the worm 303 drives the worm wheel 305 to drive the handle shaft 105 to rotate; the driving gear 603 on the handle shaft 105 rotates and drives the rack 602 to lift;

referring to the figures, the rack 602 moves down to push the seat plate 606 flat, transforming the crutch into a seat; the rack 602 moves upward to fold the seat plate 606 and stick to the main body rod 103; the limiting rope 601 is tensioned when the seat plate 606 is pushed flat, so that the rack 602 is prevented from moving excessively; the worm 303 and the worm wheel 305 are self-locking, and positioning can be enhanced;

in addition, the cam 401 on the handle shaft 105 also rotates; the lifting plate 402 is always abutted against the cam 401 under the action of the pressure spring 405, so that when the cam 401 rotates, the lifting plate 402 is lifted immediately and drives the inserted link 501 to move synchronously through the connecting rod 406; when the seat plate 606 is pushed to be flat, the tip of the cam 401 presses the lifting plate 402, the bottom end of the inserted link 501 exceeds the bottom end of the bottom cover 102, and the inserted link is inserted into the ground for fixing, so that the supporting stability of the crutch is improved; when the seat plate 606 is folded, the base circle section of the cam 401 presses the lifting plate 402, and the bottom end of the inserted link 501 is higher than the bottom end of the bottom cover 102, so that the interference to the bottom cover 102 can be avoided when the crutch is used.

In addition, when the device is switched to a seat, effective supporting and fixing can be realized, the device can also be used as a leg pressing tool, specifically, the supporting support 104 can be used as a leg pressing rod, and different leg pressing strengths can be improved due to the adjustable height of the leg pressing rod.

In another embodiment, the middle section of the handle shaft 105 is also provided with a rubber sleeve 106, which is convenient for a user to use as a crutch; it is suggested that the rubber sleeve 106 is fitted between two cams 401, the two cams 401 being located between two driving gears 603.

Example 3

On the basis of the above-described embodiments,

also comprises a grabbing component 7; the grabbing component 7 comprises a fixing plate 701, a third shaft 702, a third adjusting hand wheel 703, a moving rod 704, an internal thread groove 705, a clamping jaw 706 and a second analogized pull rod 707;

the fixing plate 701 is connected between the lower sections of the two main body frames and is positioned above the supporting legs 101; the supporting legs 101 are hollow rods, and movable rods 704 capable of sliding up and down are arranged in the supporting legs; the upper section of the movable rod 704 is provided with an internal thread groove 705; a third shaft 702 penetrates through and is rotatably connected with the fixing plate 701, a third adjusting hand wheel 703 is arranged at the top end, a thread is processed at the lower section of the third shaft, and the third shaft is screwed into an inner thread groove 705; the supporting legs 101 extend into the bottom cover 102, a plurality of clamping jaws 706 are uniformly arranged along the circumferential direction, and the top ends of the clamping jaws 706 are hinged with the supporting legs 101; the bottom end of the movable rod 704 extends out of the support leg 101, a plurality of second-class pull rods 707 are uniformly arranged along the circumferential direction, one end of each second-class pull rod 707 is hinged with the movable rod 704, and the other end of each second-class pull rod 707 is hinged with the clamping jaw 706.

Wherein, the inner ring of the supporting leg 101 is a square section, and the section of the movable rod 704 is a corresponding square; four clamping jaws 706 and four analogical pull rods 707 are arranged to form four groups;

specifically, the movable rod 704 can only move up and down on the supporting leg 101, and the third shaft 702 is rotated through the third adjusting handwheel 703, so that the movable rod 704 can lift up and down based on the screw thread effect; referring to the attached drawings, the hinge point of the second analogia pull rod 707 and the clamping jaw 706 is close to the top end of the second analogia pull rod 707, the moving rod 704 moves downwards, even if the second analogia pull rod 707 drives the clamping jaw 706 to fold, the moving rod 704 moves upwards to drive the second analogia pull rod 707 to drive the clamping jaw 706 to open, so that the object can be grabbed, and the functionality is strong; and the jaws 706 are retracted into the bottom housing 102 when fully open, also avoiding interference when used solely as a crutch.
