model relates to a joint limiting device, in particular to a two-connecting unit attached to two limbs of a limb by controlling, indirectly limiting the two A joint limiting device that can move relative to the limbs and avoid excessive flexion and extension of the joints. [Previous technology] ^ Generally due to sports injuries, accidents and diseases, joints are severely damaged by strong external forces or bacterial invasion, such as knee joint injuries caused by car accidents. Those who have suffered injuries must enter the knee joints. For surgical treatment or implantation of artificial joints, after the operation is completed, it is necessary to follow the instructions of the medical staff to accept rehabilitation arrangements at various stages. During the rehabilitation period, improper postures or excessively large thighs and calves should be avoided. Relative movement and excessive knee flexion and extension affect the healing of the wound and the progress of rehabilitation. 20 Therefore, in order to avoid the above situation, some patients will use a fixed frame, bracket and fixing band outside the injury to limit the position, so as not to cause relative movement of the limbs around the injury, and to affect the joints. The most appropriate protection is provided, while other m's may be covered with flexible auxiliary equipment such as elastic solutions and knee pads outside the wound, so that their limbs can be restrained to a certain degree when they are moving, which reduces the direct impact on the joints. Chance. Due to the solid movement of the limbs, in addition to the restraints such as the use of fixed positioning methods to protect the injured area that cannot be fully moved, and the inconvenience of proper movements at the joints, in addition to the inconvenience of post-injury and During surgery 6 M249629 For muscles and joints, it may cause atrophy and contractures, or slow down the rate of recovery. The pain and inconvenience caused by this will deepen. In addition, flexible assistive devices such as elastic end bands and knee pads can provide a relatively free range of motion for the limbs, but when the knee joint has excessive flexion and extension without warning, it cannot be immediately limited, so that the patient still suffers secondary The possibility of injury makes subsequent treatment and rehabilitation work more troublesome. [New content] Therefore, the object of the present invention is to provide a joint-limiting 10-position device that can regulate the relative movement of two limbs in a limb and prevent excessive flexion and extension of the joint. Therefore, the new joint restraint device is detachably attached to one side of a limb of a vertebrate. The limb includes two limbs and a joint combining the two limbs. The joint restraint device includes two The connection unit 1 of the connection end and the joint unit having at least one stopper and connecting the two connection ends respectively and the at least one connection unit connected can be relatively pivoted, and provide two connections by abutting against the stopper The unit is relatively rotatable. When Erlian ^ Shan 7L is attached to the same side of each limb, the joint unit is roughly located next to the limb relative to the joint position. 20 Make ㈣, determine the range of joint flexion and extension according to the joint treatment and rehabilitation of the injured person. Attach the joint limiting device to the side of the injured person's limb after adjusting the restraint on the joint unit. Above, so that the Guan Ji position device can be linked with the limbs, at this time the two connection units are respectively connected to the two limbs of the joint ^. When the injured person moves, the two limbs can face each other, and the two connecting units are pivoted with the joint unit as the center. When the amplitude of the rotation 7 M249629 is too large and exceeds the setting on the device, the connecting unit will be against the close. The joint of the cymbal restricts the limb with the joint restricting device. 5 10 _This new joint limiter uses the joint unit to set the two joints 70 for relative rotation, so that the two joint units can be used as a fixed frame when they are not pivoted, and the relative rotation between the angles to match various In addition to meeting the needs of some patients who do not move their joints, patients with different degrees can also enable other patients who teach joints to ride. They can be adjusted at any time according to the condition and rehabilitation, in order to increase the degree of joint flexion, improve circulation and Muscle tension can also prevent the joint from being overstretched due to accidents and unforeseen factors, which can increase the condition of the injured person and achieve the effect of joint limitation. [Embodiment] The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the detailed description of the preferred embodiment with the reference pattern of α at 15 °. It must be noted in the following description that the similar numbers will be used for similar components, and the setting position of this joint limiter device will be described using human legs', but not limited to this, it can also be human Limbs of other animals such as hands. 20 Referring to FIG. 1, FIG. 2 and FIG. 3, the new joint limiting device 2 in this embodiment is an adjustable fixture 2, which includes an upper connection unit 31, two connection units 31, and — , Lower connection unit 3m, 31, Guanlu unit 41, the upper connection unit 3m and lower connection unit 31 'can be attached to the same side of thigh U and lower leg 12, respectively, and the joint unit 8 yuan 41 is It is located roughly on the side of the joint 13. ^ The structure of the lower connection unit 31, 3 1 'is the same. The structure of the upper connection unit 7L 31 will be described in detail below. To facilitate understanding, the components of the lower connection unit 3Γ are the same as those of the upper connection unit 31. No., except that the number "31" is used to adjust the attachment length to the legs. The body is usually a hollow collapsible ^ J which is inserted into an elongated member. The embodiment includes—a flat rectangular parallelepiped upper substrate 311 and—connected to the upper substrate 311 and collectively defining—the upper slot 3 ”upper cover. The upper 10 substrate 311 is usually a metal body and is far away from the joint unit 41 One end is formed through the upper inner bolt hole 312, and is connected to the upper cover 15 on the outer surface side. The main function of the upper base plate 311 is to connect other components, and it can be rotated relative to the joint unit 41 when the leg moves. The upper cover The body 313 is a long body with a U-shaped cross section, and the material is plastic in this embodiment, but it can also be other materials. One end of the U-shaped opening of the upper cover 313 卩 is detachably attached to the upper substrate 311 And together with the upper substrate 311 An upper 20 slot 314 is defined for an upper extension plate 315 to be slidably inserted and removed for adjusting the length attached to the leg to increase the stability of the fixture 2. In addition, the upper cover 313 is away from the joint unit One end of 41 forms an upper and outer bolt hole 316 corresponding to the upper and inner bolt holes 312, and communicates with the upper and outer bolt holes 316 penetrating through the upper slot 314, for fixed use when adjusting the upper extension plate 315, and an upper blocking abutment wall 317 is provided at the other end edge. The upper slot 314 is closed. An upper cover connecting section 318 extends vertically from the outer wall surface of the upper blocking wall 317 in the direction of the joint unit 41 to be detachably connected to the upper base plate 31. The upper extension plate 315 is A metal body that can be made of the same material as the upper substrate 311, 9 M249629 can be correspondingly embedded in the upper slot 314, and along its length direction, a corresponding upper inner bolt hole 3 12 and upper outer bolt hole 316 are formed and adjusted above. Hole 319. The upper extension plate 315 can match the length of the leg to adjust the length embedded in the upper slot, and use the upper fixing screw 320 to sequentially pass through the upper and outer screw inspection holes 5 316, the upper adjustment hole 319, and the upper inner bolt. Hole 312, the upper cover 313, upper The extension plate 315 and the upper base plate 311 are tightly screwed (see FIG. 4). The upper base plate 311 is on the inner wall surface close to one end of the joint unit 41, and the upper extension plate 315 is on the inner wall surface retracted from one end of the joint unit 41. Each upper pad 321 is connected, and the upper pad 321 is mainly used as a smooth connection interface, so that the legs have a better comfort when the fixture 2 is provided. The upper pad 321 has a shape corresponding to the leg and its The cross section is a part of a ring-shaped upper body 322, and a sleeve section 323 is located on the outer surface of the upper body 322. The upper body 322 abuts against the legs with its inner surface, and shares with the upper sleeve section 323. A hole 324 is defined for the fixing belt to pass through to fasten the holder 2 to the leg. When the 15 legs ' is bound with other therapeutic rehabilitation products such as elastic bandages, an inner surface of the body 322 in contact with the legs may be added with a fixing element such as a devil's adhesive 325 to increase the fixing effect. In this embodiment, the lower connection sheet & 31 also has the same components and structure as the above upper connection unit, the only difference is that the upper and lower connection 20 units 31, 31 'are attached to different parts of the leg, Therefore, it is the same as the components attached to the legs in the upper connection unit 31, such as the lower substrate 3m, the lower cover 313 ', and the lower extension plate 315, but the length will be different, but it is not limited to this. More details. On the other hand, a claw-shaped latching body 326 attached to the joint unit 41 and providing a leg flexion and restraint by engaging with the joint unit 41 10 M249629 is connected to an end of the upper substrate 311 near the joint unit 41 It is a flat metal body, and has a claw portion 327 and an arm portion 328 connected to the claw portion 327. A pivot hole 329 is formed in the center of the claw portion 327 for connection with the joint unit 々I. The arm portion 328 is detachably connected to the upper base plate 311 at one end away from the claw portion 327. The joint unit 41 is mainly used to connect and set the relative rotation angle between the two connecting units 31, 31, which indirectly restricts the leg portion. The activity includes an angle adjuster 411 and two limit pins 412 which can be inserted on the angle adjuster 411. The angle adjuster 411 has two round and flat adjusting discs 413 corresponding to left and right and spaced apart. Each of the adjusting discs 413 forms a corresponding pivoting hole 329 and an engaging hole 414 passing therethrough. The claw-shaped latching body 3 26 can be embedded into the two adjusting discs. In 413, the pivot lever 415 is penetrated through the joint hole 414 and the pivot hole 329, and the latch body 326 is rotatably connected between the two adjusting disks 413. In addition, in one diameter direction of each adjusting disk 413 and corresponding to both sides of the joint hole 414, angle adjustment holes 416 penetrating and equally spaced are respectively provided, and the angle adjustment holes 4 and 6 on one side are used for setting. The connection unit 31 and the lower connection unit 31 can be relatively extended between them, and the adjustment hole 416 on the other side is used to adjust the angle between the two units 31 and 31, which can be retracted. The two limiting pins 412 can pass through the angle adjusting holes 416 of the two adjusting disks 413 from the outside to the inside. One of the limiting pins 412 is used to limit the extension angle, and the other limiting pin 412 is used to set the flexion angle so that the card can be locked. When the claw portion 327 of the pawl body 326 rotates between the two adjusting disks 413, it can be restrained from front to back (see Figs. 5 and 6). The two limit pins 412 can be respectively connected to the pivot lever 415 with an anti-falling strap 417, to prevent the limit pin 412 from being pulled out of the angle adjustment 11 M249629 hole 416 and falling to the ground when adjusting the limit angle. Furthermore, 'the peripheral edge of each adjusting disk 413 correspondingly protrudes a disk body connecting section 418 in a direction away from the joint hole 414, so that the lower substrate 3 11 approaches one end of the joint unit 41' can be lost in the two disk body connecting section. 418, and the lower connection unit 31 and the joint unit 41 can be connected by a fixed component. In this embodiment, the angle adjusting holes 416 are located on the adjusting disc 413 alternately and spaced apart, and the angle formed between each two adjusting holes 416 and the center of the disc body is 10 degrees, but it is not limited to this, and it is used according to the actual use Sex. In addition, the unit 41 can also be an angle adjustment member in other aspects, not limited to the angle adjuster 411 with the adjustment hole 416 in this example. For example, it can be an adjustment disk 413 with an arc-shaped insertion hole 422 ( (See FIG. 7) and the adjuster 411 (see FIG. 8) with the limit stop 424. At this time, the limit pin 412 can be replaced with inserting protrusions 423 provided on opposite ends of the claw portion 327 of the latch body 326, respectively. . On the other hand, in order to prevent the position-limiting pin 412 from being loosened from the engaging hole 414, a transparent protective cover 419 which is attached to the outer adjusting disk 413 and can be pivoted may be additionally provided. The protective cover 419 is connected to the angle adjuster 411 by a pivot lever 415. The protective cover 419 is an acrylic transparent cover that matches the shape of the adjusting plate 413 and defines a cylindrical chamber 42 between the outer adjusting plate 413 and the cover. The limiting pin 412 inserted into the angle adjusting hole 416 can be located in the receiving chamber 42 and not fall off. In addition, to facilitate the adjustment of the angle, a cutout 421 communicating with the receiving chamber 420 is formed on the protective cover 4 丨 9. 0421 is needed to adjust the position of the limit lock 412 to determine the angle of the limit. During use, place the holder 2 horizontally, and turn the knife 1 on the protective cover 419 above the two limit pins 412, and insert the two limit pins 412 into the joint holes according to the angle at which the joint 13 can flex and extend 12 On the angle adjustment holes 416 on the opposite sides of 414, set the angles that can be stretched and retracted respectively, and then turn the notch 421 so that it does not oppose either of the two limit pins 412, avoiding the limit pin 412 on Loosen while moving legs. Secondly, according to the length of the thigh 11 and the calf 12, determine the length of the binding. You can loosen the two fixing screws 320 and 320 'connecting the early element 31 31, adjust the extension plates 315, 315, and the exposed length, and then fix Screws 32 and 32 are locked. Then, using a fixing belt and other related fixing objects, pass through the through holes 324 and 324 to fix the two connection units 3 1 and 3 1 ′ on one side of the thigh ii and the calf 12 respectively. At this time, the angle adjuster The position of 411 is generally located beside the corresponding joint 13. When the user ’s big leg and the lower leg u, 12 move relative to each other, the two connecting units 31, 31 'will be linked together. Once the flexion and extension angle is too large, one of the claw ends of the claw card 326 will abut against a limit pin. On 412, the two connecting units 31 and 31 connected to Guan Yidan το 41 cannot continue to rotate relative to each other, and the relative movement of the thigh U and the calf 12 is produced together-the effect of restraint, so that the joint 13 will not be produced. Excessive flexion and extension cause secondary damage. In the above description, the new joint limit device has an adjustable angle adjuster 4U, and the limit pin 412 is used to set the rotation angle of the adjuster 4 to adjust the rotation angle of the adjuster ′, which can be connected to the two connection units on the adjuster 411 respectively. M, "", when the relative rotation occurs, because the latching body 326 is caught in it-the limit pin is generated, and the movement is restricted, so that the joint with the device does not cause excessive flexion and extension. On the other hand The new type of joint limit device can also be used as a limit device for fixing the folded limb in the case of a fracture, so that the injured limb can be regarded as safe during the medical treatment, so it can indeed achieve the purpose of closing. 13 ¥ 249629 However, the above are only the preferred embodiments of the new model. When the scope of the implementation of the new model cannot be limited by this, that is, the simple equivalent changes and modifications made according to the scope of the patent application for the new model and the content of the new specification. Both should still fall within the scope of the patent of the new model.
