Description

Technical Field

[0001] The invention belongs to the technical field of medical care, and specifically discloses a medical care device for leg surgery. Background Art

[0002] With the accelerated pace of life, the number of vehicles on the road has increased, and traffic accidents have increased year by year. As a result, more patients have suffered leg injuries, which has led to surgical treatment of their legs. Patients need to stay in bed for a long time after surgery, which leads to leg muscle atrophy and requires postoperative rehabilitation training for their legs.

[0003] In the past, medical care used health protection devices after leg surgery. Since the patient's legs have not been exercised for a long time, muscle atrophy has occurred over time, affecting the patient's normal activities. For those who have been bedridden for a long time, the connecting ligaments in the feet have been inactive for a long time, resulting in atrophy, which in turn causes low exercise intensity and poor mobility of the leg muscles. At the same time, the nurse needs to pull the patient's legs for stretching exercises. Since the patient has not exercised for a long time, the connecting ligaments in the feet have atrophied excessively. When the nurse pulls the patient's legs, he cannot pay attention to the extension range of the patient's legs, causing secondary damage to the patient's legs. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a medical care device for leg surgery.

[0007] In the above technical solution, preferably, the upper end of the telescopic rod is fixedly connected to the inner top of the folding plate, and the lower end of the main spring is fixedly connected to the upper end of the fixed plate near the outer side of the telescopic rod.

[0008] In the above technical solution, preferably, the upper end of the main spring is fixedly connected to the inner top of the folding plate close to the outer side of the telescopic rod, and there are multiple groups of the limiting belts.

[0009] In the above technical solution, preferably, the rear end of the limiting rod is fixedly connected to the front end of the support plate, and there are two groups of limiting rods, and the rear end of the limiting rods in the other group is fixedly connected to the front end of the docking plate.

[0010] In the above technical solution, preferably, a handle is fixedly provided on the upper end of the connecting rod, one end of the sliding rod is fixedly connected to one end of the base near the rear side of the slide rail, and one end of the auxiliary spring is fixedly connected to one end of the connecting frame.

[0011] In the above technical solution, preferably, the other end of the auxiliary spring is fixedly connected to one end of the base near the outer side of the slide rod, the upper end of the auxiliary slide is fixedly connected to the lower end of the placement plate near the front side of the linkage frame, and the axial center lines of the connecting frame, threaded head and linkage rod are located on the same straight line.

[0012] In the above technical solution, preferably, a seat cushion is fixedly provided on the upper end of the base, and a support column is fixedly provided on the other end of the base.

[0013] In the above technical solution, preferably, a backrest is fixedly provided on the upper end of the support column, and there are two groups of support columns.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By driving the docking plate to move and causing the docking plate to pull the folding plate to move, the support plate is rotated downward, which can facilitate the patient's legs to stretch outward, thereby facilitating the patient's leg rehabilitation training. At the same time, the main spring rebounds upward and causes the main spring to push the folding plate to move upward, so that the folding plate drives the patient's knees to move upward, thereby achieving the goal of quickly retracting the patient's legs.

[0016] The bolts are unscrewed, and the folding plate is pushed, so that the main slide slides along the slide rail, and the linkage mechanism moves as a whole, so that the distance between the folding plate and the base becomes longer, and then the bolts are screwed into the inside of the mounting frame and then screwed into the inside of the slide rail, so that the mounting frame is limited to the upper end of the slide rail, so that it is convenient to adjust the leg position according to patients of different heights, so as to adapt to patients of different heights.

[0017] By unscrewing the limit rod and then screwing the limit rod into the inner side of a new set of threaded grooves, the purpose of limiting the movement range of the limit block driven by the limit rod can be achieved, thereby facilitating the purpose of limiting the movement range of the support plate and the docking plate, thereby avoiding the caregiver from over-stretching the patient's legs and thus avoiding secondary injury to the patient's legs.

[0018] By pulling the connecting rod and making the placement plate drive the connecting frame to slide along the slide rod to stretch the secondary spring, the purpose of facilitating the operation of the caregiver can be achieved. After the patient has completed the leg rehabilitation exercise, the connecting rod is pulled again, and the placement plate drives the connecting frame to slide along the slide rod to stretch the secondary spring. Therefore, the secondary spring always maintains an inward contraction force, and the patient's arm can be exercised, thereby achieving the purpose of multi-functional rehabilitation training.

By unscrewing the limiting rod 588 and then screwing the limiting rod 588 into the inner side of a new set of threaded grooves 587, the purpose of limiting the movement range of the limiting rod 585 to drive the limiting block 586 can be achieved, thereby facilitating the purpose of limiting the movement range of the support plate 55 and the docking plate 510, thereby avoiding the nurse from over-stretching the patient's legs. The patient's legs are moved inwards to avoid secondary injuries to the patient's legs, and then the handle 611 is released, so that the auxiliary spring 64 contracts inwards, so that the linkage frame 62 drives the placement plate 61 to move in the opposite direction, and the placement plate 61 pushes the docking plate 510 to move in the opposite direction, so that the patient's feet are retracted backwards, and at the same time the main spring 514 rebounds upwards and makes the folding plate 59 move upwards, so that the folding plate 59 drives the patient's knees to move upwards, so that the knees and feet are retracted inwards at the same time, and the patient completes a set of leg rehabilitation training, by pulling the linkage rod 610 and making the placement plate 61 drive the linkage frame 62 to slide along the slide bar 63 to stretch the auxiliary spring 64, which can facilitate the operation of the caregiver, and after the leg rehabilitation training, the patient pulls the linkage rod 610 again,The placement plate 61 drives the linkage frame 62 to slide along the slide rod 63, thereby stretching the auxiliary spring 64, so that the auxiliary spring 64 always maintains the force of inward contraction, and can exercise the patient's arm, thereby achieving the purpose of multi-functional rehabilitation training, by driving the docking plate 510 to move and making the docking plate 510 pull the folding plate 59 to move, so that the support plate 55 rotates downward, it can be convenient to drive the patient's legs to stretch outward, thereby facilitating the patient's leg rehabilitation training, and at the same time the main spring 514 rebounds upward, and the main spring 514 pushes the folding plate 59 to move upward, Therefore, the folding plate 59 drives the patient's knee to move upward, so that the patient's legs can be quickly retracted. The bolt 53 is unscrewed and the folding plate 59 is pushed, so that the main slide 56 slides along the slide rail 51. At the same time, the linkage mechanism 6 moves as a whole, so that the distance between the folding plate 59 and the base 1 becomes longer. Then, the bolt 53 is screwed into the inside of the mounting frame 52 and then screwed into the inside of the slide rail 51. Thus, the mounting frame 52 is confined to the upper end of the slide rail 51, making it easy to adjust the leg position according to patients of different heights, thereby adapting to patients of different heights.
