Interactive wearable device for total knee arthroplasty perioperative period

Abstract

The invention discloses an interactive wearable device for total knee arthroplasty perioperative period. The device comprises a knee joint interactive wearable device and a total knee arthroplasty remote management platform. The knee joint interactive wearable device comprises a knee joint rehabilitation training mechanism and a control system; the knee joint rehabilitation training mechanism comprises clamps and a movement support, the clamps comprise thigh clamps, shank clamps and knee clamps, and the clamps are in transmission connection through the movement support; and the control system comprises a data acquisition unit, an intelligent analysis unit, a data transmission unit and a feedback unit. The comfortable and light breathable wearable device is provided, and man-machine interaction type exercise is carried out; through big data deep learning, a personalized exercise scheme is planned, and the scheme is continuously improved; in addition, through a multi-leading sensing technology, motion mode monitoring and early warning are carried out, secondary injury to the knee joint is avoided, and the rehabilitation effect of the knee joint is enhanced; and meanwhile, through collection and analysis of physiological indexes, complication monitoring and early warning are carried out, and lethal complication is avoided.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an interactive wearable device used in the perioperative period of total knee replacement. Background technique [0002] Total knee arthroplasty is an effective method for the treatment of end-stage knee osteoarthritis, and it is the last choice when conservative treatment fails. The recovery of knee joint function in patients after surgery is affected by many factors, not only related to the surgery itself, but also depends on the knee joint training in the perioperative period (preoperative and postoperative). Therefore, perioperative (preoperative and postoperative) training plays an important role in the recovery of knee joint function in patients. However, the current problems include: (1) There is a huge demand for knee joint training during the perioperative period of joint replacement, and the number of surgeons, rehabilitation physicians, and rehabilitation n...

AI Technical Summary

Problems solved by technology

However, the current problems include: (1) There is a huge demand for knee joint training during the perioperative period of joint replacement, and the number of surgeons, rehabilitation physicians, and rehabilitation nurses is insufficient, making it difficult to provide sufficient training resources; (2) Traditional knee joint training The training requires close observation of the individual condition of the patient, such as observing whether the patient suffers from dizziness, severe pain and other discomforts, effective guidance is very important

[0006] External wearable exoskeleton devices have the defects of low wearing fit and poor patient experience. Due to the heavy equipment and complicated structure, the wearing effect is not good

And most of the equipment adopts rigid structure and hard materials, which makes the patients feel poor wearing experience;

[0007] Wearable devices have the defect of single exercise content

Most of the equipment only involves flexion and extension of the lower limbs, the exercise only involves the quadriceps, and the exercise effect of the surrounding muscle groups is relatively poor, which is also a common shortcoming of most knee joint rehabilitation devices in the prior art

And the built-in exercise mode is mainly passive training, causing muscle strain, pain, and movement phobia, which is not conducive to long-term exercise

[0008] Poor fit and stability of equipment

Most of the connection between the fixed rod and the calf frame is a sliding connection, but the action point of the human leg will change during application, and this kind of equipment is not conducive to the stable control of flexion and extension movements;

[0009] In addition, wearable devices do not provide human-computer interactive training guidance for patients, the exercise effect and safety of patients cannot be guaranteed, and patients cannot achieve their ideal training goals

[0010] 2. Lack of complication monitoring and early warning functions

[0011] Many unexpected complications may occur during postoperative rehabilitation, such as infection, dislocation, etc. After searching the literature, it is found that the existing invention technology lacks the functions of complication monitoring, identification, early warning and intervention

[0012] 3. The remote rehabilitation system lacks deep learning empowerment

The system only has monitoring and collection functions, but lacks independent analysis and deep learning functions. It also has the disadvantage of consuming medical resources, and the effect of remote guidance is poor.
