Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and specifically relates to a thumb joint clamping device for the treatment of tenosynovitis. Background Technology
[0002] Tenosynovitis is a common injury to the tendons and tendon sheaths, especially affecting the thumb joint. It is caused by frequent thumb or wrist movements, leading to repeated friction between the extensor pollicis brevis and abductor pollicis longus tendons within the tendon sheath at the radial styloid process, resulting in an aseptic inflammatory reaction. Clinical manifestations mainly include a bulge and pain at the radial styloid process, which worsens with wrist and thumb movement, and local tenderness.
[0003] Currently, treatment methods for tenosynovitis include conservative treatment (such as immobilization, medication, and physical therapy) and surgical treatment. Among these, immobilization, which restricts thumb movement and reduces friction between the tendon and tendon sheath, is an important conservative treatment method.
[0004] However, most existing thumb tenosynovitis correctors use soft materials to correct the patient's thumb. These materials are prone to bending and deformation under the natural force of the fingers, resulting in unsatisfactory corrective effects. Utility Model Content

[0027] Please refer to Figure 1A thumb joint clamping device for treating tenosynovitis includes a back hand base plate 100, a palm base plate 200, a tightening component 300, an elastic clamping block 400, and an adhesive tape 500. The back hand base plate 100 is attached to one side of the back of the hand, and the palm base plate 200 is attached to one side of the palm. The back hand base plate 100 and the palm base plate 200 are arc-shaped clamps made of lightweight aluminum alloy or high-strength plastic, with a width of 1.5cm-2.5cm and a thickness of 0.3cm-0.5cm. The length of the back hand base plate 100 is slightly longer than the length of the palm base plate 200. The length of the back hand base plate 100 is 8cm-15cm, and the length of the palm base plate 200 is 8cm-12cm. The length of the back hand base plate 100 can extend from the tip of the thumb to near the wrist, and the length of the palm base plate 200 can extend from the tip of the thumb to near the palm, forming a precise clamping of the thumb joint and avoiding wrapping of the entire thumb.
[0028] The tightening component 300 is disposed on the back of the hand substrate 100 and is connected to the palm substrate 200. Tightening the tightening component 300 causes the back of the hand substrate 100 and the palm substrate 200 to move closer to each other. When the tightening component 300 is tightened, the thumb is held between the back of the hand substrate 100 and the palm substrate 200.
[0029] The elastic clamping blocks 400 are respectively disposed on the back of the hand base plate 100 and the palm base plate 200, and a pair of elastic clamping blocks 400 are disposed opposite to each other. The elastic clamping blocks 400 are made of medical-grade silicone or soft rubber. The inner side of the elastic clamping block 400 has an arc-shaped structure to conform to the curve of the thumb joint. The length is about 3cm-4cm and the width is 1.5cm-2cm, covering the proximal phalanx area of the thumb. The outer side of the elastic clamping block 400 can be glued to the back of the hand base plate 100 and the palm base plate 200, or the elastic clamping block 400 can be snapped onto the back of the hand base plate 100 and the palm base plate 200.
[0030] The adhesive tape 500 is respectively disposed at the end of the back of the hand base plate 100 and the end of the palm base plate 200. Specifically, the adhesive tape 500 is a disposable adhesive tape. One end of the adhesive tape 500 is attached to the back of the hand base plate 100 and the palm base plate 200, and the other end is attached to the back of the hand and palm of the patient with tenosynovitis. The adhesive tape 500 is a medical adhesive tape, which is easy to obtain and convenient to use.
[0031] As described in detail, the back-of-hand base plate 100 is attached to the back of the patient's thumb, and the palm base plate 200 is attached to the palm of the patient's thumb. The elastic clamping block 400 acts on the patient's thumb joint. The adhesive tape 500 is used to attach to the back of the patient's hand and palm to fix the back-of-hand base plate 100 and the palm base plate 200. After the thumb is clamped, the adhesive tape 500 is removed for the next use. By tightening the tightening component 300, the initial pressure should be such that the elastic clamping block 400 contacts the thumb but without obvious pressure. With use and adaptation, the pressure can be gradually increased to a moderate tightness, without causing pain or skin whitening. This clamping device has a simple structure and is easy to use; the clamping of the base plates on both sides avoids bending deformation caused by the natural force of the fingers; and unlike traditional wrap-around fixation, the double-sided clamping design provides good breathability and is suitable for long-term wear; furthermore, the elastic clamping block 400 can achieve targeted mechanical control of the thumb joint. This resulted in the correction of the patient's thumb and improved the correction effect.
[0032] As a further description, the tightening assembly 300 includes a rotating retractable member 310 and a tensioning strip 320. A pair of rotating retractable members 310 are respectively disposed on the back of the hand base plate 100. One end of the tensioning strip 320 is detachably connected to the palm base plate 200, and the other end of the tensioning strip 320 passes through the back of the hand base plate 100 and retracts into the rotating retractable member 310. The method of retracting the tensioning member using the retractable member is simple and convenient. For example, when worn on the right thumb, the tensioning strip 320 can be retracted simply by the patient rotating the rotating retractable member 310 with their left hand.
[0033] In Example 1, the rotating retraction component 310 is a rotating nut, and the tensioning component is a threaded rod. One end of the threaded rod is detachably connected to the palm base plate 200, and the detachable connection can be either a snap-fit or a hinge. The other end of the threaded rod passes through the back of the hand base plate 100 and is screwed onto the rotating nut. By turning the rotating nut, the threaded rod is retracted, thereby causing the back of the hand base plate 100 and the palm base plate 200 to move closer to each other. Specifically, the thread on the threaded rod is a fine-pitch thread to achieve precise adjustment. Specifically, the diameter of the threaded rod is 4mm to avoid the threaded rod being too heavy and occupying too much space.
[0034] In Example 2, the rotating retractable component 310 is a hollow retractable ratchet, and the tensioning component is a pull cable. One end of the pull cable is detachably connected to the palm base plate 200, and the detachable connection can be achieved by snap-fit or hinge. The other end of the pull cable passes through the back of the hand base plate 100 and is tightened into the hollow retractable ratchet. By turning the hollow retractable ratchet, the pull cable is retracted into the hollow retractable ratchet, thereby causing the back of the hand base plate 100 and the palm base plate 200 to move relative to each other and move closer together. Specifically, the method of retracting the pull cable into the hollow retractable ratchet is a conventional method and will not be described in detail here.
[0035] In a preferred embodiment, the back of the hand base plate 100 is provided with side ears 110 on both sides, and the rotating retractable member 310 is rotatably disposed on the side ears 110. The side ears 110 provide a larger twisting space, making it easier for the patient to twist the rotating retractable member 310.
[0036] Furthermore, since the tensioning strip 320 is located on both sides of the thumb, the thumb will rub against the tensioning strip 320 during left or right movement, causing a decrease in thumb comfort. Therefore, the tightening component 300 also includes a flexible sleeve 330, which is sleeved on the tensioning strip 320 and located between the back of the hand base plate 100 and the palm base plate 200. When the thumb moves left or right, it will come into contact with the flexible sleeve 330. At the same time, when the tensioning strip 320 retracts, it will compress the flexible sleeve 330, causing it to bend slightly. The contact between the thumb and the flexible sleeve 330, due to its softness, can improve thumb comfort.
[0037] Specifically, the flexible sleeve 330 is a flexible plastic tube.
[0038] Specifically, the flexible sleeve 330 is a flexible corrugated pipe.
[0039] In one possible embodiment, to more stably fix the back of the hand base plate 100 and the palm base plate 200 to the thumb without displacement, a thumb joint clamping device for treating tenosynovitis further includes a rubber finger sleeve 600, which is detachably connected to the back of the hand base plate 100 and the palm base plate 200, and the rubber finger sleeve 600 is located on the side away from the adhesive tape 500. The rubber finger sleeve 600 has different specifications and sizes. For example, a small rubber finger sleeve 600 is used for children's thumbs or women's thumbs, and a large rubber finger sleeve 600 is used for adult men. Because the rubber finger sleeve 600 is elastic, it can fit on the thumb nail. The back of the hand base plate 100 and the palm base plate 200 are detachably connected to the rubber finger sleeve 600. When the rubber finger sleeve 600 is worn on the thumb, it can stably fix one end of the back of the hand base plate 100 and the palm base plate 200. The other end of the back of the hand base plate 100 and the palm base plate 200 are attached to the back of the patient's hand and palm by the adhesive tape 500, thereby stably fixing the back of the hand base plate 100 and the palm base plate 200 on the patient's thumb and preventing the back of the hand base plate 100 and the palm base plate 200 from shifting.
[0040] Furthermore, the rubber finger sleeve 600 is provided with a pair of hinge ears 610, and the hinge ears 610 are provided with through holes 611. The back of the hand base plate 100 is provided with a first hinge post 120, and the palm base plate 200 is provided with a second hinge post 210. The first hinge post 120 passes through the through hole 611 and is detachably connected to the hinge ear 610, and the second hinge post 210 passes through the through hole 611 and is detachably connected to the hinge ear 610. The material of the hinge ear 610 is the same as that of the rubber finger sleeve 600. A through hole 611 is provided on the hinge ear 610. The first hinge post 120 and the second hinge post 210 are engaged in the through hole 611, realizing the detachable connection between the hinge ear 610 and the first hinge post 120 and the second hinge, making installation more convenient. The first hinge post 120 and the second hinge are interference-fitted with the through hole 611, that is, the through hole 611 is enlarged, and the first hinge post 120 and the second hinge are sleeved in the through hole 611, preventing the first hinge post 120 and the second hinge from disengaging from the through hole 611.
[0041] Furthermore, the surface of the rubber finger sleeve 600 is evenly provided with a plurality of ventilation holes 620. When the rubber finger sleeve 600 is worn on the tip of the thumb, it increases the breathability between the rubber finger sleeve 600 and the thumb.
[0042] In one possible embodiment, when the adhesive tape 500 fails to adhere to the patient's back of hand and palm, in order to better fix the back of hand base plate 100 and palm base plate 200 to the patient's thumb, a thumb joint clamping device for treating tenosynovitis further includes two binding straps 700. One binding strap 700 is detachably connected to the back of hand base plate 100, and the other binding strap 700 is detachably connected to the palm base plate 200. The binding straps 700 are located on one side of the adhesive tape 500. By using the two binding straps 700, the binding straps 700 are tied to the patient's wrist, achieving double fixation through the binding straps 700 and the adhesive tape 500, thus fixing the back of hand base plate 100 and palm base plate 200 to the patient's thumb for a long time. Even if the adhesive tape 500 fails to adhere, the binding straps 700 can still fix the back of hand base plate 100 and palm base plate 200. When the patient discovers that the adhesive tape 500 has failed to adhere, a new adhesive tape 500 can be used.
[0043] In one possible embodiment, to improve the treatment effect on thumb tenosynovitis, a thumb joint clamping device for treating tenosynovitis further includes a far-infrared medicated patch 800. The far-infrared medicated patch 800 is adhered to the inner side of the elastic clamping block 400, facing the thumb joint. When the elastic clamping block 400 is brought close to the thumb joint, the far-infrared medicated patch 800 first adheres to the thumb joint. The adhesion of the far-infrared medicated patch 800 to the inner side of the elastic clamping block 400 prevents it from falling off. Furthermore, the elastic clamping block 400 is flexible, capable of adhering to and covering the thumb joint, thus allowing the far-infrared medicated patch 800 to also adhere to and cover the thumb joint. This combination of thumb fixation and medication improves the treatment effect on thumb tenosynovitis.
[0044] For a detailed description and explanation of the far-infrared patch 800, please refer to the utility model application with application number CN201320829302.0, which provides a detailed description.
[0045] In a preferred embodiment, a double-sided adhesive tape 810 is attached to the far-infrared patch 800. The double-sided adhesive tape 810 is located between the elastic clamping block 400 and the far-infrared patch 800. One side of the double-sided adhesive tape 810 is adhered to the elastic clamping block 400, and the other side is adhered to the far-infrared patch 800. After one treatment with the far-infrared patch 800 for thumb tenosynovitis, the patch becomes ineffective. For the next treatment, a new far-infrared patch 800 needs to be replaced. The far-infrared patch 800, along with the double-sided adhesive tape 810, is peeled off the elastic clamping block 400. A new double-sided adhesive tape 810 is then attached to the elastic clamping block 400, and the far-infrared patch 800 is reattached to the double-sided adhesive tape 810 before the next treatment. The double-sided adhesive tape 810 enables quick and easy application of the far-infrared patch 800, making replacement more convenient and faster.
[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
