Problems solved by technology

[0002] In clinical practice, due to knee injury or postoperative contracture of the soft tissues, joint capsule or hamstring muscles around the knee joint, the knee joint is flexed and the knee joint cannot be passively straightened in some patients.
Usually, some rehabilitation techniques are used for smooth recovery, but due to the limited duration of force, effective rehabilitation cannot be achieved with smooth rehabilitation techniques. Therefore, external forces such as stretching devices must be used to assist in achieving the purpose of rehabilitation.
[0003] However, most patients after knee arthroplasty have a "rebound problem" when recovering the knee flexion angle. The range of motion of the joint increases after the therapist's training, and the range of motion of the joint becomes smaller after going home, or because there is no professional exercise method and It is difficult to effectively recover the range of motion of the knee joint due to unattended exercise

Embodiment 1

[0027] see Figures 1 to 5 In the embodiment of the present invention, an active stretching and rehabilitation device for knee joint surgery includes a fixing base 1 on which a stretching mechanism is installed, and the stretching mechanism includes fixing cylinders fixed on both sides of the upper end of the fixing base 1 4. The telescopic cylinder 5 is slidably installed inside the fixed cylinder 4. The telescopic cylinder 5 and the fixed cylinder 4 are composed of hollow pipes. During the adjustment process, the shortest 15cm and the longest 50cm can be reached. A seat 7 is installed between the tops of the telescopic columns. The placement seat 7 is formed of a concave latex pad, so that the patient can protect and relieve the compressed state of the nerves and blood vessels around the popliteal fossa during the traction process. A spring column 12 is also hinged on the fixed seat 1, a buckle 13 is installed on the top of the spring column 12, and a traction mechanism 14 i...

Embodiment 2

[0035] In another embodiment of the present invention, the difference between this embodiment and the above-mentioned embodiment is that a lower reinforcing rib 3 is installed between the two fixed cylinders 4 , and an upper reinforcing rib 3 is installed between the two telescopic cylinders 5 . The reinforcing rib 6 finally ensures the mechanical strength of the drafting mechanism during operation, and further improves the stability of the device.

[0036] The working principle of the present invention is as follows: when in use, the patient can first clamp the entire placement seat 7 in the popliteal fossa under the knee joint, then fix the clamping assembly at the bottom of the leg, and then under the action of the limiting assembly, After adjusting the height of the entire device, you can achieve self-stretching rehabilitation training, and the entire operation process is fast and convenient.

Abstract

The invention relates to the technical field of rehabilitation instruments, and discloses a knee joint postoperative active drafting rehabilitation device which comprises a fixing seat, a drafting mechanism is mounted on the fixing seat and comprises fixing cylinders fixed to the two sides of the upper end of the fixing seat, telescopic cylinders are slidably mounted in the fixing cylinders, and a placement seat is mounted between the tops of the telescopic cylinders. A limiting assembly used for limiting the lifting position of the telescopic cylinder is further installed on the outer side of the upper end of the fixing cylinder, a spring column is further hinged to the fixing base, a retaining ring is installed on the top of the spring column, and a traction mechanism is installed on the retaining ring. According to the traction rehabilitation device, the limiting assembly is arranged on the traction mechanism, the vertical height of the whole device can be adjusted, the traction rehabilitation requirements of patients with different heights from children to adults are met, meanwhile, under the action of the traction mechanism, self traction of the patients can be achieved, assistance of external personnel is not needed, and the traction rehabilitation device is convenient to use. The application range of the device is further widened, and the device is worthy of application and popularization.

Description

technical field [0001] The invention relates to the technical field of rehabilitation equipment, in particular to an active stretching rehabilitation device after knee joint operation. Background technique [0002] In clinical practice, some patients have contractures of the soft tissue around the knee joint, joint capsule or hamstring muscle due to knee injury or postoperative surgery, resulting in the flexion of the knee joint and the inability to passively straighten the knee joint. Usually, some rehabilitation techniques are used to achieve smooth rehabilitation, but the successful rehabilitation methods cannot achieve effective rehabilitation due to the limited duration of strength, so external forces such as stretching devices must be used to assist in achieving the purpose of rehabilitation. [0003] However, most patients after knee surgery have "rebound problems" when restoring knee flexion. The range of motion increases after the therapist's training, and the range...
