Leg muscle rehabilitation training device and control method thereof

Abstract

The invention discloses a leg muscle rehabilitation training device and a control method thereof. Including the screw nut pair driven by the servo motor, the nut cover and its supporting bearings and motor frame, guide rails, squat auxiliary modules, lifting hands, pallet hands, buffer dampers, external frame, main console and control system and several feedback sensors. Among them, the screw nut pair is used to change the rotation of the servo motor into direct motion, the nut cover is used to cooperate with the guide rail, the guide rail is used for precise guidance, the squat auxiliary module is designed for lifting hands, and the pallet hand is used to transfer wires. The power of the bar nut pair, the buffer damper is to buffer the impact of the patient when squatting, and its resistance can be adjusted. The main console is to record various physiological parameters and exercise parameters of the patient in real time. The invention patent can enable patients to perform multi-joint compound rehabilitation training mainly based on squats (assisted squats) from scratch, and has the function of recording and analyzing the patient's movement conditions and physiological parameters.

Description

technical field [0001] The patent of the present invention relates to the fields of rehabilitation medicine, sports rehabilitation and mechanical design, more specifically, a leg muscle rehabilitation training device and its corresponding control method. Background technique [0002] In the era when human living standards are gradually improving, the rehabilitation of postoperative patients has been paid more and more attention. For example, after arthroscopic repair of the meniscus, the affected muscles of the patient will be accompanied by varying degrees of atrophy and functional loss, and the patient's core muscle groups (erector spinae and abdominal muscles) will also suffer from functional loss. In response to this phenomenon, foreign countries use physical therapy to intervene and treat, and the effect is remarkable, but its price is high and limited by space and time. For this kind of postoperative rehabilitation in China, the plan at the general medical level is on...

Problems solved by technology

[0003] Most of the rehabilitation devices that have been used in rehabilitation medicine require patients to have good motor nerve recruitment ability, but for our country, the threshold of existing rehabilitation devices is too high, and it is difficult when patients just start rehabilitation training. Large, easy to discourage patients' enthusiasm, and most of the existing rehabilitation devices do not have real-time feedback and recording functions according to the patient's condition, and are highly dependent on rehabilitation doctors, generally requiring on-site and real-time guidance from doctors

[0004] More importantly, most of the rehabilitation equipment used in rehabilitation medicine today uses single-joint isolated movements as rehabilitation movements, without paying attention to and mentioning the patient's muscle functionality and nervous system coordination, and ignoring the patient's sports performance rehabilitation needs; Rehabilitation of patients with single-joint isolated movements is ineffective and takes a long time, which will have a long-term and serious impact on the quality of life of patients; and for patients who have been bedridden for a long time, it is not only the affected muscles Function, and to a deeper extent, also caused damage to the function of the core muscle group and the overall sports performance of the patient. It can be seen that the single-joint isolated movement cannot achieve the multi-joint compound movement (squat) adopted in the patent of the present invention anyway. rehabilitation effect
