Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a wall-climbing device for the recovery of the affected limb after breast cancer surgery. Background Art

[0002] The female breast is composed of skin, fibrous tissue, mammary glands and fat. Breast cancer is a malignant tumor that occurs in the mammary gland epithelial tissue. 99% of breast cancers occur in women, and only 1% in men. After surgery, since all the fat and lymphatic tissue in the armpit are removed, a cavity is formed in the patient's armpit, and the skin wound surface needs to be closely attached before exercise. However, due to lack of exercise for a long time, problems such as muscle atrophy and joint stiffness may occur in the patient. During postoperative rehabilitation, targeted exercise of the joints of the affected limb is required.

[0003] For this reason, the Chinese patent with the publication number "CN207769045U" discloses a "wall-climbing instrument for the recovery of the affected limb after breast cancer surgery". Its main structure includes a base and a simulated wall panel. On both sides of the front of the simulated wall panel, a row of retaining bars are symmetrically arranged along its height direction. Two retaining bars at the same height on both sides of the simulated wall panel form a wall ladder for holding a hand-held rod. Horizontally along its height direction on the back of the simulated wall panel, several support bars are arranged, and at the end of each support bar, an adsorption leather tile for adsorbing the wall surface is provided. This wall-climbing instrument for the recovery of the affected limb after breast cancer surgery makes the simulated wall panel fit completely stably with the wall by using the base, support bars and adsorption leather tiles. Then, a row of retaining bars are symmetrically arranged on both sides of the front of the simulated wall panel. Thus, when the patient exercises, by holding the hand-held rod and rising step by step on the retaining bars at the same height on the two rows of retaining bars, targeted exercise of the affected limb and joints is carried out, promoting an increase in the range of motion of the shoulder joint and reducing the incidence of lymphedema, enabling the patient to more easily grasp the exercise intensity and avoid excessive movement.

[0004] However, when the above-mentioned wall-climbing instrument for the recovery of the affected limb after breast cancer surgery is actually used, it is adsorbed on the surface of the wall, and a layer of putty is applied to the surface of the real wall. The adsorption force between the putty and the wall is limited. After the suction cup adsorbs on the surface of the putty, it needs to bear the gravity of the human body. Therefore, it is easy to cause the putty to fall off the wall and cause an accident, and its potential safety hazard during use is relatively high. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a wall-climbing device for the recovery of the affected limb after breast cancer surgery. By using a support height adjustment mechanism with adjustable height, the component of the human body gravity in the longitudinal direction is transmitted to the ground to the greatest extent, and the component of the human body gravity in the horizontal direction can be offset by the suction cup, thereby reducing the acting force of the patient on the putty in the wall during climbing, so as to reduce the potential safety hazard during the use of the device and solve the above technical problems.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figure 1 and Figure 2, A wall-climbing device for the recovery of the affected limb after breast cancer surgery, including a longitudinal climbing rod 1 with a first docking plate 2 at the bottom, a plurality of climbing handrails 3 linearly and arrayedly fixedly installed on one side of the longitudinal climbing rod 1, a total gas adsorption cavity 4 arranged inside the longitudinal climbing rod 1, an air inlet 5 arranged at the top of the total gas adsorption cavity 4 and equipped with a gas valve inside, a plurality of first gas flow holes 6 linearly and arrayedly arranged on the other side of the longitudinal climbing rod 1 and communicating with the total gas adsorption cavity 4, and a bottom support base 9 that supports the longitudinal climbing rod 1. The exercise can be carried out according to the following steps: 1. The patient faces the simulated wall, straightens both arms, holds the climbing handrails 3 with both hands, and the healthy limb drives the affected limb to move up step by step along the climbing handrails 3, repeating several times; 2. The patient turns sideways so that the body is perpendicular to the wall, and the affected limb holds the climbing handrail 3 with one hand and moves up step by step along the front of the wall, repeating several times. And during operation, an air extraction device is needed. The air extraction port of the air extraction device is docked with the air inlet 5 through a pipeline. When the air extraction device works, the gas inside the device can be absorbed and discharged outwards to form a negative pressure.

[0018] To achieve a longitudinally displaceable adsorption effect, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , it is necessary to set up a plurality of longitudinally telescopic adsorption mechanisms 7, which are internally provided with a longitudinal hollow outer shell 71 fixedly installed on one side of the longitudinal climbing rod 1 and whose internal structure communicates with the total gas adsorption cavity 4, a suction cup 78 fixedly installed on one side of the longitudinal hollow outer shell 71 and communicating with the internal structure of the longitudinal hollow outer shell 71 and capable of adsorbing on the wall, so that the adsorption surface of the suction cup 78 abuts against the wall. The negative pressure will cause the suction cup 78 to tightly adsorb on the wall. At this time, when a small longitudinal displacement occurs, the piston plate 75 will move correspondingly inside the longitudinal component activity cavity 72. Therefore, the suction cup 78 will not be affected by the longitudinal force, that is, it will not be affected by the longitudinal component of the human body gravity, so as to achieve a longitudinally displaceable adsorption effect.

[0019] Regarding the specific structure of the longitudinally telescopic adsorption mechanism 7, please refer to Figure 3 and Figure 4, including a longitudinal hollow housing 71. Inside the longitudinal hollow housing 71, there is a longitudinal component activity cavity 72. At the bottom end of the longitudinal hollow housing 71, there is a curved gas flow channel 73 which is of an integral structure with it, fixedly installed on the side of the longitudinal climbing rod 1 and communicates the longitudinal component activity cavity 72 and the first gas flow hole 6. At the top end of the longitudinal hollow housing 71, there is a rod body perforation 74 that communicates the outside space and the top end of the longitudinal component activity cavity 72. Inside the longitudinal hollow housing 71 and located within the longitudinal component activity cavity 72, there is a piston plate 75 that can move axially along the longitudinal component activity cavity 72. At the bottom of the piston plate 75, there is a helical spring 76. On the upper surface of the piston plate 75, there is a curved telescopic rod 77 which is of an integral structure with it and has a hollow interior. At one end of the curved telescopic rod 77 located outside the longitudinal hollow housing 71, there is an adsorption disc 78 fixedly installed. Around the open end of the adsorption disc 78, there is an annular embedding groove 79 with an in - concave structure. Inside the annular embedding groove 79, there is an annular sealing ring 710 embedded. The bottom end of the helical spring 76 is fixedly installed on the bottom end face of the longitudinal component activity cavity 72, and the top end face is fixed on the bottom surface of the piston plate 75. Moreover, the initial length of the helical spring 76 is greater than the depth of the longitudinal component activity cavity 72. The structural shape of the cross - section of the rod body perforation 74 is the same as that of the cross - section of the curved telescopic rod 77, both being polygonal structures, and the structural dimensions of the cross - section of the rod body perforation 74 match those of the cross - section of the curved telescopic rod 77.

[0020] To achieve the function of adjustable longitudinal height support, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 , it is necessary to set up a support height adjustment mechanism 8. Inside it, there are a first external threaded rod 86 and a second external threaded rod 87 which are connected to the bottom support base 9 and the end of the first docking plate 2, a longitudinal threaded sleeve 81 which is threadedly connected to the first external threaded rod 86 and the second external threaded rod 87 and can change the distance between the first external threaded rod 86 and the second external threaded rod 87 when rotating, and a polygonal limiting rod 811 inserted at the axis of the first external threaded rod 86 and the second external threaded rod 87 to prevent the relative rotation between the first external threaded rod 86 and the second external threaded rod 87. By rotating the longitudinal threaded sleeve 81, since the spiral direction of the first thread structure 84 is opposite to that of the second thread structure 85, and during the rotation process, due to the existence of the polygonal limiting rod 811, the first external threaded rod 86 and the second external threaded rod 87 will not rotate relatively. Therefore, the distance between the first external threaded rod 86 and the second external threaded rod 87 will change, thus realizing the function of adjusting the support height. After the longitudinal height adjustment is completed, the support height adjustment mechanism 8 can bear the longitudinal component force of the human body, thereby reducing the acting force on the wall.

[0021] For the specific structure of the support height adjustment mechanism 8, please refer to Figure 5 and Figure 6 , including a longitudinal threaded sleeve 81, a first external threaded rod 86 and a second external threaded rod 87. One end of the longitudinal threaded sleeve 81 is provided with a first internal threaded cavity 82 with a concave structure, and the other end of the longitudinal threaded sleeve 81 is provided with a second internal threaded cavity 83 with a concave structure. The rod body of the first external threaded rod 86 is installed inside the first internal threaded cavity 82 through a first threaded structure 84, and the rod body of the second external threaded rod 87 is installed inside the second internal threaded cavity 83 through a second threaded structure 85. The opposite ends of the first external threaded rod 86 and the second external threaded rod 87 are provided with a polygonal limiting cavity 810 with a concave structure. A polygonal limiting rod 811 inserted into the polygonal limiting cavity 810 is fixedly installed at the center of the longitudinal threaded sleeve 81. One end of the first external threaded rod 86 is provided with a first connecting plate 88 integrally formed therewith and fixedly connected to the bottom support base 9. One end of the second external threaded rod 87 is provided with a second connecting plate 89 integrally formed therewith and fixedly connected to the first docking plate 2. The outer circumferential surface of the longitudinal threaded sleeve 81 is provided with a polygonal knob structure 812 integrally formed therewith and facilitating rotation. The structural shape of the cross-section of the polygonal limiting cavity 810 is the same as that of the cross-section of the polygonal limiting rod 811, both being polygonal structures, and the structural dimensions of the cross-section of the polygonal limiting cavity 810 match the structural dimensions of the cross-section of the polygonal limiting rod 811. The first threaded structure 84 includes an internal threaded structure provided inside the first internal threaded cavity 82 and an external threaded structure provided on the rod body of the first external threaded rod 86. The second threaded structure 85 includes an internal threaded structure provided inside the second internal threaded cavity 83 and an external threaded structure provided on the rod body of the second external threaded rod 87, and the spiral direction of the first threaded structure 84 is opposite to the spiral direction of the second threaded structure 85.

[0022] In use, an air extraction device is required. The air extraction port of the air extraction device is docked with the air suction port 5 through a pipeline. When the air extraction device works, the gas inside the device can be absorbed and discharged outward to form a negative pressure. The negative pressure will cause the suction disc 78 to tightly adsorb on the wall surface. Rotate the longitudinal threaded sleeve 81 directionally. Since the spiral direction of the first threaded structure 84 is opposite to the spiral direction of the second threaded structure 85, and during the rotation process, due to the existence of the polygonal limiting rod 811, the first outer threaded rod 86 and the second outer threaded rod 87 will not rotate relative to each other. Therefore, the distance between the first outer threaded rod 86 and the second outer threaded rod 87 will change, thereby realizing the function of adjusting the support height. When a small longitudinal displacement occurs, the piston plate 75 will move correspondingly inside the longitudinal component activity cavity 72. Therefore, the suction disc 78 will not be affected by the longitudinal force, that is, it will not be affected by the longitudinal component of the human body gravity, thereby realizing the longitudinally displaceable adsorption effect. When exercising, the following steps can be followed for exercise: 1. The patient faces the simulated wall surface, straightens both arms, holds the climbing handrail 3 with both hands, and the healthy limb drives the affected limb to move upward step by step along the climbing handrail 3, repeating several times; 2. The patient turns sideways so that his body is perpendicular to the wall surface, and the affected limb holds the climbing handrail 3 with one hand and moves upward step by step along the front of the wall surface, repeating several times.

[0023] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and deformations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
