Leg muscle rehabilitation training instrument and control method thereof

Abstract

The invention discloses a leg muscle rehabilitation training instrument and a control method thereof. The leg muscle rehabilitation training instrument comprises a lead screw nut pair and a nut outercover driven by a servo motor, and a bearing, a motor frame, a guide rail, a deep squatting auxiliary module, a lifting hand, a tray hand, a buffer damper, an outer frame, a main console, a control system and the feedback sensors are matched with the nut outer cover. The lead screw nut pair is used for changing the rotation of the servo motor into linear motion; the nut outer cover is matched withthe guide rail; wherein the guide rail is used for accurate guiding, the deep squatting auxiliary module is used for lifting hand assembly design, a tray hand is used for transmitting power of the lead screw nut pair, the buffer damper is used for buffering impact of a patient during squatting movement, the resistance of the buffer damper is adjustable, and the main console is used for recordingvarious physiological parameters and movement parameters of the patient in real time. According to the invention, a patient can carry out multi-joint compound rehabilitation training based on deep squatting (auxiliary deep squatting) from zero basis, and the training instrument has the function of recording and analyzing the movement condition and physiological parameters of the patient.

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
