Description

Technical Field

[0001] The present invention particularly relates to a postoperative rehabilitation auxiliary device for breast cancer. Background Art

[0002] Functional exercises for the affected limb after breast cancer surgery usually include fist clenching exercises, arm flexion exercises, wall climbing exercises, and upper limb lifting exercises.

[0003] Most of the existing functional methods are exercised by patients in the form of gymnastics. This method is not quantified or expressed in other specific forms during the exercise process. It depends entirely on the patient's self-conscious exercise. Some patients will not perform the movements properly or even stop exercising as the exercise time increases, which will greatly reduce the training effect.

[0004] In addition, there are devices on the market that are specifically designed to train the function of the affected limbs after breast cancer surgery. However, such devices often only train a certain movement, such as only being able to train one of the following movements: fist clenching exercises, shoulder joint extension exercises, upper limb raising exercises, etc. If the patient needs to perform different exercises, different devices must be configured, which is bound to cause certain troubles to the patient.

DETAILED DESCRIPTION

[0035] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] See Figures 1 to 5 The present invention provides a postoperative rehabilitation auxiliary device for breast cancer, including a support frame 100, a cantilever 200, a mounting frame 300, a connecting piece 400, a fist clencher 500 and a counter 600.

[0037] Specifically, a support frame 100 is vertically supported on the ground. A cantilever 200 is horizontally disposed on the support frame 100. A mounting frame 300 is disposed on the cantilever 200. A connector 400 is disposed on the mounting frame 300. A fist clencher 500 is disposed on the mounting frame 300 via the connector 400 and is used to train a patient to clench their fist. A counter 600 is disposed on the connector 400 and is connected to the fist clencher 500, and counts each fist clenching movement.

[0038] During use, the patient clenches his fist with the clenching device 500, and the counter 600 counts each time the patient clenches his fist. This allows the patient's fist clenching movements to be quantified, thereby providing guidance for the patient's rehabilitation exercises.

[0039] Specifically, the fist clencher 500 includes an inflatable ball 510, a two-way valve, and an air tube 520. The inflatable ball 510 is mounted on the connector 400. The air tube 520 is connected to the inflatable ball 510, and the end of the air tube 520 is connected to a counter 600, which can count when impacted by airflow. The two-way valve is mounted within the air tube 520. When impacted by airflow, the two-way valve is opened by the airflow, leaving the air tube 520 in a one-way state. The counter 600 then drives the airflow to open the two-way valve.

[0040] When in use, a certain amount of gas is first inflated into the inflatable ball 510. When the inflatable ball 510 is squeezed with a fist, the airflow pushes open the two-way valve, and the counter 600 counts once when the airflow impacts it. When the inflatable ball 510 is released, the counter 600 pushes the airflow back to open the two-way valve, allowing the airflow to flow back into the inflatable ball 510.

[0041] In this embodiment, the counter 600 includes an air cylinder 610, a piston, a first elastic member, a plug rod 640, a winder 650, a counting belt 660, a first toggle tooth 670, a first stopper 680, a support rod, and a toggle rod 690. The air cylinder 610 is fixed to the connecting member 400. The piston is disposed in the air cylinder 610, dividing the inner cavity of the air cylinder 610 into a first inner cavity and a second inner cavity that are not connected. The air pipe 520 is connected to the first inner cavity. The first elastic member is disposed in the second inner cavity and is supported between the piston and the inner wall of the air cylinder 610. The plug rod 640 is disposed on the piston and extends from the air cylinder 610 through the second inner cavity.

[0042] There are two winders 650, which are installed on the connecting member 400 at intervals. The two ends of the counting tape 660 are respectively wound on the two winders 650. The winders 650 can automatically reel in the wire, and the counting tape 660 can be pulled out from the winders 650. One side of the counting tape 660 is provided with gradually increasing numbers. On the other side of the counting tape 660, a plurality of first toggle teeth 670 are provided at intervals along the length direction, and a first stopper 680 is provided on the counting tape 660 near each first toggle tooth 670. The first stopper 680 abuts against the first toggle tooth 670, and the support rod is fixed on the connecting member 400. The middle part of the toggle rod 690 is hinged to the top end of the support rod, and one end of the toggle rod 690 is slidably plugged into the plug rod 640. The other end extends between two adjacent toggle teeth. When air is taken into the first inner cavity, the plug rod 640 extends outward to drive the toggle rod 690 to toggle the first toggle tooth 670 into contact, thereby driving the counting belt 660 to move.

[0043] During use, when the inflatable ball 510 is squeezed, gas opens the two-way valve and enters the gas cylinder 610, pushing the plug rod 640 toward the second inner cavity and driving one end of the toggle rod 690 forward. The other end of the toggle rod 690 moves backward to toggle the first toggle tooth 670. When the inflatable ball 510 is released, the plug rod 640 is pushed back under the action of the restoring force of the first elastic member. The plug rod 640 drives the toggle rod 690 backward, and the other end of the toggle rod 690 overlaps the first toggle tooth 670 and slides. Since the first toggle tooth 670 is hinged to the plug rod 640 and there is no first stop 680 to block it, it will not push the digital belt to move. Subsequently, by clenching your fist and squeezing the gas cylinder 610 again, the digital belt can be toggled to move again. When the digital belt moves, the winder 650 on the front side of the forward digital belt reels in the line, and the winder 650 on the rear side releases the line. In specific implementation, the wire winder 650 can be similar to the winding structure of the conventional measuring tape in the prior art. After the exercise is finished, the number of fist clenching can be calculated by adding the initial number to the counting number.

[0044] In this embodiment, the mounting frame 300 is a semicircular frame with an opening downward, and a semicircular guide groove 310 is provided on the mounting frame 300. The connecting member 400 can be slidably set in the guide groove 310. For each side of the fist, the fist clencher 500 can drive the connecting member 400 to slide upward one grid along the guide groove 310.

[0045] When in use, the shoulder is located at the center of the mounting frame 300, the person faces one end of the mounting frame 300, and then the affected limb grasps the airbag. Each time a fist is clenched on one side, the fist clencher 500 can drive the connecting piece 400 to slide upward one grid along the guide groove 310, forming an imitation wall climbing exercise, so that the upper limb is slowly raised.

[0046] Specifically, teeth 320 are spaced apart on the sidewalls of the guide slot 310. The connector 400 includes a connecting rod 410, a mounting plate 420, a second elastic member 430, a rotating shaft 440, a first gear 450, a second gear 460, a second shifting tooth 470, and a second stopper 480. The mounting plate 420 is located outside the mounting bracket 300. L-shaped stoppers are positioned at opposite ends of the mounting plate 420. The stoppers are hooked onto the inner side of the mounting bracket 300.

[0047] The second elastic member 430 is supported between the mounting plate 420 and the outer side of the mounting frame 300. The rotating shaft 440 is rotatably mounted on the mounting plate 420 and extends radially along the mounting frame 300. The first gear 450 is mounted on the lower end of the rotating shaft 440. The second gear 460 is mounted on the top end of the rotating shaft 440. The second toggle teeth are hinged to the plug rod 640. A second stopper 480 is provided on the plug rod 640, adjacent to each second toggle tooth 470. The second gear 460 meshes with the second toggle teeth 470. When the second tooth 461 of the second gear 460 and the second toggle tooth 470 move away from the side wall of the second stopper 480 and approach, the second toggle tooth 470 can toggle the second gear 460 for rotation. The connecting rod 410 is connected between the mounting plate 420 and the fist clencher 500.

[0048] During use, the user holds the inflatable ball 510, causing the second gear 460 to engage with the second shifting tooth 470, and squeezes the inflatable ball 510 while making a fist. When the plug rod 640 is extended, the second shifting tooth 470 shifts the second gear 460 to rotate, and the rotation of the second gear 460 drives the rotating shaft 440 and the first gear 450 to rotate. Under the action of the teeth 320 in the guide groove 310, the entire connecting member 400 can be driven to move upward along the guide groove 310 once. Subsequently, by continuing to make a fist, the connecting member 400 can be continuously driven to move upward along the guide groove 310, completing the wall climbing exercise. When the connecting member 400 moves to the top, the air cylinder 610 is released. Under the action of the first elastic member, the mounting plate 420 moves outward, and the first gear 450 disengages from the teeth 320. The connecting member 400 can then be moved to the bottom along the guide groove 310 for the second round of training.

[0049] In this way, fisting exercises and wall climbing exercises can be performed at the same time, thereby improving the training and rehabilitation effect.

[0050] In addition, when in use, the shoulder can be located at the center of the mounting frame 300, the person can be located in the plane of the mounting frame 300, and then the affected limb can hold the airbag. Every time the fist is clenched, the fist clencher 500 can drive the connecting part 400 to slide upward one grid along the connecting part 400, thereby performing the upper limb raising movement exercise.

[0051] As a preferred embodiment, the length of the connecting rod 410 is adjustable. The length of the connecting rod 410 can be adjusted according to the length of the upper limb of the human body to ensure that the shoulder is located at the center of the mounting frame 300. In specific implementation, the connecting rod 410 can be a sleeve rod, an insert rod and a locking member commonly used in the prior art, such as:

[0052] The connecting rod includes a first sleeve rod, a first insertion rod, and a first locking member. The first sleeve rod and the first insertion rod are slidably connected, the first sleeve rod is connected to the mounting plate, the first insertion rod is connected to the fist clencher, and the first locking member is connected between the first sleeve rod and the first insertion rod to lock and secure the first sleeve rod and the first insertion rod. Of course, in other embodiments, the sleeve rod and the insertion rod can also be connected by a threaded connection.

[0053] In addition, when in use, the patient can adjust the length of the connecting rod 410 according to the length of the forearm so that the elbow joint is located at the center of the mounting frame 300. The person faces the end of the mounting frame 300 and can perform an arm flexion exercise every time he makes a fist.

[0054] In this way, fist clenching exercises and arm flexion exercises can be performed at the same time, thereby improving the training and rehabilitation effect.

[0055] As a more preferred embodiment, a height adjustment member 700 is provided between the mounting frame 300 and the cantilever 200. The height adjustment member 700 is used to adjust the distance of the mounting frame 300 relative to the ground. At the same time, the height adjustment member 700 can also be a set rod, a plug rod and a locking member commonly used in the prior art, such as: the height adjustment member 700 includes a second set of rods, a second plug rod and a second locking member, the second set of rods and the second plug rod can be slidably plugged in, the end of the second set of rods is connected to the cantilever, the end of the second plug rod is connected to the mounting frame, and the second locking member is connected between the second set of rods and the second plug rod to lock the second set of rods and the second plug rod. By adjusting the height of the mounting frame 300, it can be adapted to patients of different heights. By driving the connecting member 400 to slide upward along the connecting member 400 one grid, the forearm can be driven to bend, and the arm flexion exercise is performed to practice the upper limb raising movement.

[0056] Specific implementation of the postoperative rehabilitation assistive device for breast cancer:

[0057] Before use, the height of the mounting frame 300 needs to be adjusted using the height adjustment member 700 according to the patient's height;

[0058] During the first stage of rehabilitation:

[0059] When in use, one only needs to hold the inflatable ball 510 and continuously make a fist. The counter 600 can count, thereby quantifying the fist-making action and improving the training effect.

[0060] In the second stage of recovery:

[0061] When using, the patient can first adjust the length of the connecting rod 410 according to the length of the forearm, and then make the elbow joint be located at the center of the mounting frame 300. The patient faces the end of the mounting frame 300 and performs an arm flexion exercise each time the fist is clenched. In this way, the fist clenching exercise and the arm flexion exercise are performed simultaneously, thereby improving the training and rehabilitation effect.

[0062] In the third stage of recovery:

[0063] During use, the patient holds the inflatable ball 510 in his hand, faces one end of the mounting frame 300, and then pulls the entire connecting frame toward the center of the circle to engage the first gear 450 with the tooth 320. Then, the patient continues to clench his fist, which can continuously drive the connecting member 400 to move upward once along the guide groove 310 to complete the wall climbing exercise, thereby performing the fist clenching exercise and the wall climbing exercise at the same time, thereby improving the training and rehabilitation effect.

[0064] In addition, when in use, the shoulder can be located at the center of the mounting frame 300, the person can be located in the plane of the mounting frame 300, and then the affected limb can hold the airbag. Each time a fist is clenched on one side, the fist clencher 500 can drive the connecting piece 400 to slide upward along the connecting piece 400 one grid to perform upper limb raising movement exercises. At the same time, since the fist clenching exercise and the upper limb raising movement exercise are performed at the same time, the training and rehabilitation effect can be improved.

[0065] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
