Description

Technical Field

[0001] The present invention relates to the field of fracture first-aid fixation devices, and specifically to a fixation device for field fracture first-aid and its usage method. Background Art

[0002] During the process of field exploration, various unexpected situations may occur. When a fall injury occurs, there is a risk of fracture. During this process, a fixation device is needed to fix the fracture position of the patient to avoid secondary injury.

[0003] The existing patent (Publication No.: CN219021848U) discloses an emergency first-aid fracture site locking device, which includes a locking ring. The locking ring is composed of two semi-circular hoop rings, and a hinge is provided at one end of the two hoop rings. In the process of implementing this solution, the following problems in the prior art are found to have not been well solved: 1. During the use of this device, the locking of the locking ring and the support rod needs to be controlled and operated separately. Since it is necessary to quickly fix the fracture position of the patient during the first-aid process to reduce the resulting injury, the operability of this operation is poor; 2. Since the diameters of different positions of the patient's limb are different, it is difficult for this locking ring to effectively wrap and fix different positions of the limb, affecting the first-aid fixation effect. Summary of the Invention

[0004] The purpose of the present invention is to provide a fixation device for field fracture first-aid and its usage method to solve the problems raised in the above background art: 1. It is difficult to quickly synchronously lock the length adjustment component and the locking ring component during the use of some existing fracture first-aid fixation devices, and the operability is poor; 2. During the use of some existing fracture first-aid fixation devices, it is difficult to automatically adapt to wrap and fix limb positions of different sizes. To achieve the above purpose, the present invention provides the following technical solution: A fixation device for field fracture first-aid, including a hoop sleeve. Two hoop sleeves are provided.

[0013] An extrusion spring is movably connected between the end of the main arc-shaped positioning rod far from the support bar and the inner wall of the main arc-shaped positioning groove. A main arc-shaped sleeve is fixedly connected to the right side of the front end of the hoop sleeve. A main pressure rod is slidably connected inside the main arc-shaped sleeve. The two ends of the main pressure rod correspond to the two ends of the two main arc-shaped positioning rods one by one.

[0014] Support rods are symmetrically and slidably connected to both sides of the hoop sleeve. An arc-shaped clamping plate is fixedly connected to one end of the support rod. A return spring is movably sleeved on the surface of the support rod. The return spring is arranged between the side wall of the arc-shaped clamping plate and the inner wall of the hoop sleeve;

[0015] Rectangular grooves are symmetrically formed on both sides of the hoop sleeve. A rectangular bar is slidably connected inside the rectangular groove. The four rectangular bars correspond to the four arc-shaped clamping plates one by one. One end of the rectangular bar penetrates through the rectangular groove and is fixedly connected to the side wall of the corresponding arc-shaped clamping plate.

An arc-shaped positioning rod is slidably connected inside the arc-shaped positioning groove. The top of the arc-shaped positioning rod is symmetrically and fixedly connected with a clamping pin. The two clamping pins correspond to the two rectangular grooves one by one.

[0017] A pressing spring is movably connected between the end of the arc-shaped positioning rod away from the rectangular bar and the inner wall of the arc-shaped positioning groove. The right side of the front end of the hoop sleeve is fixedly connected with an arc-shaped sleeve. A pressing rod is slidably connected inside the arc-shaped sleeve. The two ends of the pressing rod correspond to the ends of the two arc-shaped positioning rods one by one. A restoring spring is movably connected between the middle of the pressing rod and the inner wall of the arc-shaped sleeve.

[0018] Preferably, positioning rings are fixedly connected to the middle parts of the main arc-shaped positioning rod and the arc-shaped positioning rod respectively. The main arc-shaped positioning rod and the arc-shaped positioning rod are respectively arranged at the top and bottom of the clamping mechanism.

[0019] Preferably, the hoop sleeve is composed of two arc-shaped plates, and the ends of the two arc-shaped plates are hinged and installed.

[0020] A using method of a fixing device for first aid of field fracture includes the following steps:

[0021] S1. When in use, first place the two hoop sleeves in an open state at both ends of the fracture of the patient respectively, and then pull one hoop sleeve to adjust the position between the two hoop sleeves. After the position adjustment of the two hoop sleeves is completed, insert the clamping tooth plate at the right side of the front end of the hoop sleeve into the inside of the clamping sleeve at the left side of the front end of the hoop sleeve. At this time, the teeth of the clamping tooth plate cooperate with the clamping tooth blocks inside the clamping sleeve and can only be inserted unidirectionally. After the left and right sides of the front end of the hoop sleeve are relatively clamped to the limit position, the two hoop sleeves complete the preliminary positioning.

[0022] S2. When the hoop sleeve is wrapped around the patient's limb surface, under the action of the reset spring, the arc-shaped splints at the inner wall position of the hoop sleeve can freely press against the surfaces of limbs of different thicknesses to clamp the patient's limb. When the two sides at the front end of the hoop sleeve move relatively and are clamped tightly, the main arc-shaped sleeve and the secondary arc-shaped sleeve at the right side position of the front end of the hoop sleeve both move towards the left side position of the front end of the hoop sleeve. During this process, the main pressure rod inside the main arc-shaped sleeve inserts into the corresponding main arc-shaped positioning groove, and at the same time, the main pressure rod presses against the main arc-shaped positioning rod inside the main arc-shaped positioning groove, causing the main arc-shaped positioning rod to drive the fixedly connected positioning block to insert into the side wall position of the support bar at the chute position and cooperate with the positioning slot on the side wall of the support bar to lock the position of the support bar. At the same time, as the two sides of the hoop sleeve continue to move relatively, the main arc-shaped sleeve drives the left end of the main pressure rod to move to the limit position, causing the main pressure rod to move relatively to the main arc-shaped sleeve towards the right and press against the end of the main arc-shaped positioning rod at the right side position of the hoop sleeve to lock the support bar at the right side position of the hoop sleeve. In this way, during the locking process of the two hoop sleeves, the support bar between the two hoop sleeves is locked synchronously to limit the distance between the two hoop sleeves;

[0023] S3. Meanwhile, during the relative movement of the two sides at the front end of the hoop sleeve, the secondary arc-shaped sleeve at the right side of the front end of the hoop sleeve drives the secondary pressure rod to insert into the secondary arc-shaped positioning groove at the left side position of the front end of the hoop sleeve, causing the left end of the secondary pressure rod to press against the end face of the corresponding secondary arc-shaped positioning rod, and causing the secondary arc-shaped positioning rod to drive the fixedly connected pin to move to the position of the inclined clamping plate on the surface of the corresponding rectangular bar. During the sliding process of the pin along the surface of the inclined clamping plate, the pressed rectangular bar drives the arc-shaped splint to move a short distance towards the patient's limb surface again. Similarly, when the left end of the secondary arc-shaped positioning rod moves to the limit position, the secondary arc-shaped positioning rod moves relatively to the secondary arc-shaped sleeve towards the right and presses against the secondary arc-shaped positioning rod at the right side position of the hoop sleeve. Thus, during the further relative movement of the four arc-shaped splints in contact with the limb, the patient's limb is tightly wrapped and the hoop sleeve is stably restricted at the current position;

[0024] S4. Finally, when it is necessary to loosen the hoop sleeve, by pulling the adjusting plates on the two hoop sleeves, the inclined slots on the adjusting plates cooperate with the adjusting pins to slide. Then, the adjusting pins drive the fixedly connected clamping tooth blocks to move along the trajectory of the vertical slot. At this time, the clamping tooth blocks are in contact with the clamping state of the clamping tooth plate, and the hoop sleeve can be opened. After that, the main arc-shaped positioning rod and the secondary arc-shaped positioning rod automatically reset, and the support bar and the arc-shaped splint are released from the locked state, and the hoop sleeve can be removed.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] In the present invention, through the coordinated use of components such as the hoop sleeve, the clamping mechanism, and the clamping and positioning mechanism, when the two ends of the hoop sleeve move relatively and are locked by the clamping mechanism, the clamping and positioning mechanism can operate synchronously to clamp the patient's limb, improving the convenience of use.

[0027] In the present invention, through the combined use of components such as the hoop sleeve and the clamping and positioning mechanism, with the cooperation of the four arc-shaped splints and the return spring, it can adapt to the thickness of different positions of the patient's limb and perform clamping. Moreover, under the clamping and positioning mechanism, it can synchronously and quickly lock the arc-shaped splints after clamping, improving the first-aid fixation effect.

Detailed implementation manners

[0042] 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 work fall within the protection scope of the present invention.

[0043] Please refer to Figures 1 to 13 , the present invention provides a technical solution: a fixing device for first aid of fractures in the wild, including a hoop ring sleeve 1. There are two hoop ring sleeves 1. Four chutes 2 are opened at the bottom of the upper hoop ring sleeve 1, and four chutes 2 are opened at the top of the lower hoop ring sleeve 1. A support bar 3 is slidably connected between two opposite chutes 2.

[0044] A clamping mechanism 4 is movably connected between the two sides at the front end of the hoop ring sleeve 1, and a clamping and positioning mechanism 5 that cooperates with the support bar 3 is movably connected between the two sides at the front end of the hoop ring sleeve 1. It should be noted that: when the clamping mechanism 4 is clamped and locked, it will drive the clamping and positioning mechanism 5 to run synchronously. The clamping mechanisms 4 and the clamping and positioning mechanisms 5 on the two hoop ring sleeves 1 are arranged symmetrically.

[0045] In this embodiment, as Figures 1 to 13 shown, the clamping mechanism 4 includes a groove 401. The groove 401 is opened at the right side position of the front end of the hoop ring sleeve 1, and a clamping tooth plate 402 is hinged inside the groove 401.

[0046] A clamping sleeve 403 is fixedly connected to the left side of the front end of the hoop ring sleeve 1. A clamping groove 404 that mates with the clamping tooth plate 402 is provided on the right side of the clamping sleeve 403. An activity groove 405 is provided at both the top and bottom of the inner wall of the clamping groove 404. A clamping tooth block 406 that mates with the clamping tooth plate 402 is slidably connected inside the activity groove 405. A compression spring 407 is fixedly connected between the end of the clamping tooth block 406 and the inner wall of the activity groove 405.

[0047] An adjustment groove 408 is provided on the front side of the clamping sleeve 403. An adjustment plate 409 is slidably connected inside the adjustment groove 408. Oblique grooves 410 are symmetrically provided on the surface of the adjustment plate 409. The two oblique grooves 410 correspond to the two activity grooves 405 one by one. A vertical groove 411 is provided between the inner wall of the activity groove 405 and the adjustment groove 408. An adjustment pin 412 is fixedly connected to the side wall of the clamping tooth block 406. One end of the adjustment pin 412 passes through the vertical groove 411 and is slidably connected inside the corresponding oblique groove 410. It should be noted that: since the clamping tooth block 406 is vertically slidably arranged inside the activity groove 405, and the adjustment pin 412 is fixedly connected to the side wall of the clamping tooth block 406 and is movably arranged inside the vertical groove 411, the adjustment pin 412 can only vertically slide along with the clamping tooth block 406. When the adjustment plate 409 and the oblique groove 410 move leftward inside the adjustment groove 408, the adjustment pin 412 slides in cooperation with the oblique groove 410, causing the adjustment pin 412 to drive the clamping tooth block 406 to vertically move inside the activity groove 405. Therefore, when pulling the adjustment plate 409 to slide inside the adjustment groove 408, the oblique groove 410 on the adjustment plate 409 slides in cooperation with the adjustment pin 412, causing the adjustment pin 412 to drive the clamping tooth block 406 to move inside the activity groove 405 along the track of the vertical groove 411. At this time, the clamping tooth block 406 can be disengaged from the clamping with the clamping tooth plate 402.

[0048] In this embodiment, as Figures 1 to 13 shown, guide holes are symmetrically provided on the inner wall of the adjustment groove 408. Guide rods are symmetrically fixedly connected to the side wall of the adjustment plate 409. The two guide rods are respectively slidably connected inside the two guide holes. A pull ring is fixedly connected to the middle of the adjustment plate 409.

[0049] In this embodiment, as Figures 1 to 13 shown, the teeth of the clamping tooth plate 402 are triangular, and the end of the clamping tooth block 406 is provided with a wedge shape that mates with the clamping tooth plate 402. It should be noted that: the wedge-shaped clamping tooth block 406 mates with the teeth of the clamping tooth plate 402, which facilitates the clamping tooth plate 402 to be inserted into the clamping groove 404 of the clamping sleeve 403 and cooperate with the clamping tooth block 406 for limit locking.

[0050] In this embodiment, as Figures 1 to 13As shown in the figure, the clamping and positioning mechanism 5 includes main arc-shaped positioning grooves 501. There are two main arc-shaped positioning grooves 501, which are symmetrically arranged on both sides of the hoop sleeve 1. A main arc-shaped positioning rod 502 is slidably connected inside the main arc-shaped positioning groove 501.

[0051] A moving groove 503 matching the sliding groove 2 is formed on the inner wall of the main arc-shaped positioning groove 501. Symmetrically fixed connection positioning blocks 504 are arranged on the surface of the main arc-shaped positioning rod 502. The positioning blocks 504 are slidably connected inside the corresponding moving grooves 503. A positioning slot 505 matching the positioning block 504 is formed on the side wall of the support bar 3. It should be noted that: when the main arc-shaped positioning rod 502 drives the positioning block 504 to slide inside the moving groove 503, the positioning block 504 passes through the moving groove 503 and inserts into the positioning slot 505 on the side wall of the support bar 3 to limit the support bar 3; and a chamfer matching the positioning block 504 is formed on the inner wall of the positioning slot 505 to facilitate the insertion of the positioning block 504. The positioning slots 505 are multiple and are equidistantly arranged on the side wall of the support bar 3.

[0052] An extrusion spring 506 is movably connected between the end of the main arc-shaped positioning rod 502 away from the support bar 3 and the inner wall of the main arc-shaped positioning groove 501. The right side of the front end of the hoop sleeve 1 is fixedly connected with a main arc-shaped sleeve 507. A main pressure rod 508 is slidably connected inside the main arc-shaped sleeve 507. The two ends of the main pressure rod 508 correspond to the ends of the two main arc-shaped positioning rods 502 one by one. A return spring 509 is movably connected between the middle of the main pressure rod 508 and the inner wall of the main arc-shaped sleeve 507.

[0053] Support rods 510 are symmetrically and slidably connected to both sides of the hoop sleeve 1. One end of the support rod 510 is fixedly connected with an arc-shaped clamping plate 511. A return spring 512 is movably sleeved on the surface of the support rod 510. The return spring 512 is arranged between the side wall of the arc-shaped clamping plate 511 and the inner wall of the hoop sleeve 1. It should be noted that: the opposite sides of the four arc-shaped clamping plates 511 are made of rubber material, and the four arc-shaped clamping plates 511 are annularly arranged around the hoop sleeve 1.

[0054] Rectangular grooves 513 are symmetrically arranged on both sides of the hoop sleeve 1. A rectangular strip 514 is slidably connected inside the rectangular groove 513. The four rectangular strips 514 correspond to the four arc-shaped clamping plates 511 one by one. One end of the rectangular strip 514 penetrates through the rectangular groove 513 and is fixedly connected with the side wall of the corresponding arc-shaped clamping plate 511. An inclined clamping plate 515 is fixedly connected to the surface of the rectangular strip 514.

[0055] On both sides inside the hoop sleeve 1, arc-shaped positioning grooves 516 are provided. The arc-shaped positioning grooves 516 communicate with two rectangular grooves 513 on the same side. A secondary arc-shaped positioning rod 517 is slidably connected inside the arc-shaped positioning groove 516. Symmetrically and fixedly connected to the top of the secondary arc-shaped positioning rod 517 are latch pins 518. The two latch pins 518 correspond one by one to the two rectangular grooves 513. The upper part of the latch pin 518 is clamped at the position of the inclined clamping plate 515 on the surface of the rectangular strip 514. It should be noted that: multiple inclined clamping plates 515 are provided and fixedly connected at equal intervals on the surface of the corresponding rectangular strip 514. When the secondary arc-shaped positioning rod 517 drives the latch pin 518 to move, the latch pin 518 slides in cooperation with the inclined surface of the inclined clamping plate 515, causing the inclined clamping plate 515 to drive the rectangular strip 514 and the arc-shaped clamping plate 511 to move a short distance, enabling the arc-shaped clamping plate 511 to further perform clamping and positioning. And because the arc-shaped clamping plate 511 slides on the inner wall of the hoop sleeve 1 in cooperation with the support rod 510 and the return spring 512, the four arc-shaped clamping plates 511 inside the hoop sleeve 1 can be freely adjusted according to the thickness of the patient's limb. When the hoop sleeve 1 is clamped on the surface of the patient's limb, the return spring 512 presses against the arc-shaped clamping plate 511 to fit on the surface of the patient's limb. When the two sides of the hoop sleeve 1 are about to complete the clamping, the secondary arc-shaped positioning rod 517 drives the latch pin 518 to snap into the inclined clamping plate 515, and at the same time, the main arc-shaped positioning rod 502 drives the positioning block 504 to snap into the positioning slot 505 to complete the corresponding locking.

[0056] A compression spring 519 is movably connected between the end of the secondary arc-shaped positioning rod 517 away from the rectangular strip 514 and the inner wall of the arc-shaped positioning groove 516. A secondary arc-shaped sleeve 520 is fixedly connected to the right side of the front end of the hoop sleeve 1. A secondary pressing rod 521 is slidably connected inside the secondary arc-shaped sleeve 520. The two ends of the secondary pressing rod 521 correspond one by one to the ends of the two secondary arc-shaped positioning rods 517. A recovery spring 522 is movably connected between the middle of the secondary pressing rod 521 and the inner wall of the secondary arc-shaped sleeve 520. It should be noted that: a disc is provided at one end of the secondary arc-shaped positioning rod 517 where the compression spring 519 is located. When the compression spring 519 elastically recovers, since one end of the compression spring 519 is restricted at the position of the inner wall of the arc-shaped positioning groove 516, at this time, the other end of the compression spring 519 will push the disc and the secondary arc-shaped positioning rod 517 towards the secondary arc-shaped sleeve 520. Similarly, the reset method of the main arc-shaped positioning rod 502 is the same as that of the secondary arc-shaped positioning rod 517.

[0057] In this embodiment, as Figures 1 to 13As shown, positioning rings are fixedly connected to the middle parts of the main pressure rod 508 and the secondary pressure rod 521. The main pressure rod 508 and the secondary pressure rod 521 are respectively arranged at the top and bottom of the clamping mechanism 4. It should be noted that: through the setting of the positioning rings, when the main pressure rod 508 is not in use, the left end of the main pressure rod 508 can extend from the left end position of the main arc-shaped sleeve 507. When the two sides at the front end of the hoop sleeve 1 are mutually attached and locked, the left end of the main pressure rod 508 first contacts the main arc-shaped positioning rod 502 on the left side of the inner wall of the hoop sleeve 1. After the left end of the main pressure rod 508 fails to press the corresponding main arc-shaped positioning rod 502 to move, as the two sides in front of the hoop sleeve 1 continue to fit, at this time, the right end of the main pressure rod 508 contacts the adjacent main arc-shaped positioning rod 502, causing the main arc-shaped positioning rod 502 on the right side of the inner wall of the hoop sleeve 1 to be pressed and move; similarly, the cooperation between the secondary pressure rod 521 and the secondary arc-shaped sleeve 520 is the same as the above.

[0058] In this embodiment, as Figures 1 to 13 shown, the hoop sleeve 1 is composed of two arc-shaped plates, and the ends of the two arc-shaped plates are hinged. It should be noted that: the hoop sleeve 1 can be opened and closed under the cooperation of the two arc-shaped sleeves and the clamping mechanism 4.

[0059] In this embodiment, as Figures 1 to 13 shown, a usage method of a fixing device for first aid of field fractures includes the following steps:

[0060] S1. When in use, first place the two hoop sleeves 1 in an open state at both ends of the fracture of the patient respectively, and then pull one hoop sleeve 1 to adjust the position between the two hoop sleeves 1. After the position adjustment of the two hoop sleeves 1 is completed, insert the clamping tooth plate 402 at the right side of the front end of the hoop sleeve 1 into the inside of the clamping sleeve 403 at the left side of the front end of the hoop sleeve 1. At this time, the teeth of the clamping tooth plate 402 cooperate with the clamping teeth 406 inside the clamping sleeve 403 and can only be inserted unidirectionally. After the left and right sides at the front end of the hoop sleeve 1 are relatively clamped to the limit position, the two hoop sleeves 1 complete the preliminary positioning;

[0061] S2. When the hoop sleeve 1 is wrapped around the surface of the patient's limb, under the action of the reset spring 512, the arc-shaped clamping plate 511 at the inner wall position of the hoop sleeve 1 can freely press against the surfaces of limbs with different thicknesses to clamp the patient's limb. When the two sides at the front end of the hoop sleeve 1 move relatively and are clamped, the main arc-shaped sleeve 507 and the secondary arc-shaped sleeve 520 at the right side position of the front end of the hoop sleeve 1 both move towards the left side position of the front end of the hoop sleeve 1. During this process, the main pressure rod 508 inside the main arc-shaped sleeve 507 inserts into the corresponding main arc-shaped positioning groove 501, and at the same time, the main pressure rod 508 presses against the main arc-shaped positioning rod 502 inside the main arc-shaped positioning groove 501, causing the main arc-shaped positioning rod 502 to drive the fixedly connected positioning block 504 to insert into the side wall position of the support bar 3 at the position of the sliding groove 2 and cooperate with the positioning slot 505 on the side wall of the support bar 3 for plugging, thereby locking the position of the support bar 3. At the same time, as the two sides of the hoop sleeve 1 continue to move relatively, the main arc-shaped sleeve 507 drives the left end of the main pressure rod 508 to move to the extreme position, causing the main pressure rod 508 to move relative to the main arc-shaped sleeve 507 to the right and press against the end of the main arc-shaped positioning rod 502 at the right side position of the hoop sleeve 1, locking the support bar 3 at the right side position of the hoop sleeve 1. In this way, during the locking process of the two hoop sleeves 1, the support bar 3 between the two hoop sleeves 1 is locked synchronously, restricting the distance between the two hoop sleeves 1;

[0062] S3. At the same time, during the relative movement of the two sides at the front end of the hoop sleeve 1, the secondary arc-shaped sleeve 520 at the right side of the front end of the hoop sleeve 1 drives the secondary pressure rod 521 to insert into the secondary arc-shaped positioning groove 516 at the left side position of the front end of the hoop sleeve 1, causing the left end of the secondary pressure rod 521 to press against the end face of the corresponding secondary arc-shaped positioning rod 517, and causing the secondary arc-shaped positioning rod 517 to drive the fixedly connected pin 518 to move to the position of the inclined clamping plate 515 on the surface of the corresponding rectangular bar 514. During the sliding process of the pin 518 along the surface of the inclined clamping plate 515, it presses against the rectangular bar 514 to drive the arc-shaped clamping plate 511 to move a short distance towards the surface of the patient's limb. Similarly, when the left end of the secondary arc-shaped positioning rod 517 moves to the extreme position, the secondary arc-shaped positioning rod 517 moves relative to the secondary arc-shaped sleeve 520 to the right and presses against the secondary arc-shaped positioning rod 517 at the right side position of the hoop sleeve 1. At this point, during the further relative movement of the four arc-shaped clamping plates 511 in contact with the limb, they tightly wrap the patient's limb and stably limit the hoop sleeve 1 at the current position;

[0063] S4. Finally, when it is necessary to loosen the hoop sleeve 1, by pulling the adjusting plates 409 on the two hoop sleeves 1, the inclined slots 410 on the adjusting plates 409 are slid in cooperation with the adjusting pins 412. Then, the adjusting pins 412 drive the engaged tooth blocks 406 fixedly connected thereto to move along the track of the vertical slots 411. At this time, the engaged tooth blocks 406 are disengaged from the engaged tooth plates 402, and the hoop sleeve 1 can be opened. After that, the main arc positioning rod 502 and the secondary arc positioning rod 517 are automatically reset, so that the support bar 3 and the arc clamping plate 511 are disengaged from the locked state, and the hoop sleeve 1 can be removed.

7. A method for using a fixation device for first aid of fracture in the field, characterized in that: Using the field fracture emergency fixation device as claimed in any one of claims 1 to 6 comprises the following steps: S1. When in use, firstly, two hoop sleeves (1) in an open state are placed at the two ends of the patient's fracture, and then one hoop sleeve (1) is pulled to adjust the position between the two hoop sleeves (1). After the position adjustment of the two hoop sleeves (1) is completed, the clamping tooth plate (402) at the right position of the front end of the hoop sleeve (1) is inserted into the inside of the clamping sleeve (403) at the left position of the front end of the hoop sleeve (1). At this time, the teeth of the clamping tooth plate (402) cooperate with the clamping tooth block (406) inside the clamping sleeve (403), and can only be inserted in one direction. After the left and right sides of the front end of the hoop sleeve (1) are relatively clamped to the limit position, the two hoop sleeves (1) complete the initial positioning; S2. When the hoop sleeve (1) is wrapped around the surface of the patient's limb, under the action of the reset spring (512), the arc-shaped splint (511) at the inner wall of the hoop sleeve (1) can freely press against the limb surfaces of different thicknesses to clamp the patient's limb. When the two sides of the front end of the hoop sleeve (1) move relatively and clamp, the main arc sleeve (507) and the slave arc sleeve (520) at the right side of the front end of the hoop sleeve (1) both move toward the left side of the front end of the hoop sleeve (1). During this process, the main pressure rod (508) inside the main arc sleeve (507) is inserted into the corresponding main arc positioning groove (501). At the same time, the main pressure rod (508) presses against the main arc positioning rod (502) inside the main arc positioning groove (501), so that the main arc positioning rod (502) with the fixed The connected positioning block (504) is inserted into the side wall position of the support strip (3) at the position of the slide groove (2), and is plugged into the positioning slot (505) on the side wall of the support strip (3) to lock the position of the support strip (3). At the same time, as the two sides of the hoop sleeve (1) continue to move relative to each other, the main arc sleeve (507) moves the left end of the main pressure rod (508) to the limit position, so that the main pressure rod (508) moves to the right relative to the main arc sleeve (507) and presses against the end of the main arc positioning rod (502) at the right side position of the hoop sleeve (1), locking the support strip (3) at the right side position of the hoop sleeve (1). In this way, during the process of locking the two hoop sleeves (1), the support strip (3) between the two hoop sleeves (1) is locked synchronously, thereby limiting the distance between the two hoop sleeves (1); S3. At the same time, during the relative movement of the two sides of the front end of the hoop sleeve (1), the slave arc sleeve (520) on the right side of the front end of the hoop sleeve (1) carries the slave pressure rod (521) and is inserted into the interior of the slave arc positioning groove (516) on the left side of the front end of the hoop sleeve (1), so that the left end of the slave pressure rod (521) is pressed against the end surface of the corresponding slave arc positioning rod (517), so that the slave arc positioning rod (517) and the fixedly connected bayonet (518) move to the position of the oblique clamping plate (515) on the surface of the corresponding rectangular strip (514), and the bayonet (518) moves along the oblique clamping plate (515). 5) During the surface sliding process, the pressing rectangular bar (514) moves a short distance toward the surface of the patient's limb with the arc-shaped splint (511). Similarly, when the left end of the arc-shaped positioning rod (517) moves to the extreme position, the arc-shaped positioning rod (517) moves to the right relative to the arc-shaped sleeve (520) and presses against the position of the arc-shaped positioning rod (517) on the right side of the hoop sleeve (1). Thus, the four arc-shaped splints (511) in contact with the limb further move relative to each other, tightly wrapping the patient's limb and stably restricting the hoop sleeve (1) at the current position. S4. Finally, when the hoop ring (1) needs to be loosened, the adjusting plates (409) on the two hoop rings (1) are pulled so that the inclined groove (410) on the adjusting plate (409) and the adjusting pin (412) slide in cooperation, and then the adjusting pin (412) moves along the track of the vertical groove (411) with the fixedly connected engaging tooth block (406). At this time, the engaging tooth block (406) is released from the clamping state with the engaging tooth plate (402), and the hoop ring (1) can be opened. After that, the main arc-shaped positioning rod (502) and the secondary arc-shaped positioning rod (517) are automatically reset, so that the support bar (3) and the arc-shaped clamping plate (511) are released from the locked state, and the hoop ring (1) can be removed.
