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

[0020] A method for using a fixation device for first aid of fractures in the field, comprising the following steps:

[0021] S1. When using, first place the two hoop sleeves in the open state at the two ends of the patient's fracture, 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 position of the front end of the hoop sleeve into the inside of the clamping sleeve at the left position of the front end of the hoop sleeve. At this time, the teeth of the clamping tooth plate match the clamping tooth block inside the clamping sleeve, and can only be inserted in one direction. 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 initial positioning;

[0022] S2. When the hoop is wrapped around the surface of the patient's limb, under the action of the reset spring, the arc-shaped splint on the inner wall of the hoop can freely press against the surfaces of limbs of different thicknesses to clamp the patient's limb. When the two sides of the front end of the hoop move relatively and clamp, the main arc sleeve and the slave arc sleeve on the right side of the front end of the hoop both move toward the left side of the front end of the hoop. During this process, the main pressure rod inside the main arc sleeve is inserted into the corresponding main arc positioning groove. At the same time, the main pressure rod presses the main arc positioning rod inside the main arc positioning groove, so that the main arc positioning rod carries the fixed The connected positioning block is inserted into the side wall position of the support bar at the position of the slide groove, and is plugged into 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 ring continue to move relative to each other, the main arc sleeve brings the left end of the main pressure rod to move to the extreme position, so that the main pressure rod moves to the right relative to the main arc sleeve and presses against the end of the main arc positioning rod at the right position of the hoop ring sleeve, thereby locking the support bar at the right position of the hoop ring sleeve. In this way, during the process of locking the two hoop ring sleeves, the support bar between the two hoop ring sleeves is locked synchronously, thereby limiting the distance between the two hoop ring sleeves.

[0023] S3. At the same time, during the relative movement of the two sides of the front end of the hoop sleeve, the slave arc sleeve on the right side of the front end of the hoop sleeve carries the slave pressure rod into the slave arc positioning groove at the left position of the front end of the hoop sleeve, so that the left end of the slave pressure rod presses against the end face of the corresponding slave arc positioning rod, so that the slave arc positioning rod with the fixedly connected latch moves to the oblique clamping plate position on the corresponding rectangular bar surface. During the sliding process of the latch along the oblique clamping plate surface, the rectangular bar is pressed to carry the arc splint to move a short distance toward the surface of the patient's limb. Similarly, when the left end of the slave arc positioning rod moves to the extreme position, the slave arc positioning rod moves to the right relative to the slave arc sleeve and presses against the slave arc positioning rod position on the right side of the hoop sleeve. At this point, the four arc splints in contact with the limb further move relative to each other, tightly wrapping the patient's limb and stably restricting the hoop sleeve to the current position.

[0024] S4. Finally, when the hoop sleeve needs to be loosened, the adjusting plates on the two hoop sleeves are pulled to make the oblique grooves on the adjusting plates slide in conjunction with the adjusting pins. Then the adjusting pins move along the track of the vertical grooves with the fixedly connected engaging tooth blocks. At this time, the engaging tooth blocks are in contact with the engaging tooth plates in a clamping state, and the hoop sleeve can be opened. After that, the main arc-shaped positioning rod and the secondary arc-shaped positioning rod are automatically reset, so that the support bar and the arc splint are unlocked, and the hoop sleeve can be removed.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

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

[0027] In the present invention, through the coordinated use of components such as the hoop sleeve and the clamping and positioning mechanism, the four arc-shaped splints, in cooperation with the reset spring, can adapt to the thickness of the patient's limbs at different positions and clamp them. Moreover, under the clamping and positioning mechanism, the clamped arc-shaped splints can be locked synchronously and quickly, thereby improving the first aid fixation effect.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0043] See also Figures 1 to 13 The present invention provides a technical solution: a fixation device for emergency treatment of fractures in the field, comprising a hoop sleeve 1, two hoop sleeves 1 are provided, four slide grooves 2 are provided at the bottom of the upper hoop sleeve 1, and four slide grooves 2 are provided at the top of the lower hoop sleeve 1, and a support bar 3 is slidably connected between the two slide grooves 2.

[0044] A clamping mechanism 4 is movably connected between the two sides of the front end of the hoop sleeve 1. A clamping and positioning mechanism 5 is movably connected between the two sides of the front end of the hoop sleeve 1 and cooperates with the support bar 3. It should be noted that when the clamping mechanism 4 is engaged and locked, it also drives the clamping and positioning mechanism 5 to operate synchronously. The clamping mechanisms 4 and clamping and positioning mechanisms 5 on the two hoop sleeves 1 are arranged in a symmetrical manner.

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

[0046] The left side of the front end of the hoop sleeve 1 is fixedly connected to a clamping sleeve 403, and the right side of the clamping sleeve 403 is provided with a clamping groove 404 that cooperates with the clamping tooth plate 402. The top and bottom of the inner wall of the clamping groove 404 are provided with movable grooves 405. The inside of the movable groove 405 is slidably connected to a clamping tooth block 406 that cooperates with the clamping tooth plate 402, and a compression spring 407 is fixedly connected between the end of the clamping tooth block 406 and the inner wall of the movable groove 405.

[0047] An adjustment groove 408 is provided on the front side of the clamping sleeve 403, and an adjustment plate 409 is slidably connected to the inside of the adjustment groove 408. The surface of the adjustment plate 409 is symmetrically provided with oblique grooves 410, and the two oblique grooves 410 correspond one-to-one to the two movable grooves 405. A vertical groove 411 is provided between the inner wall of the movable groove 405 and the adjustment groove 408, and an adjustment pin 412 is fixedly connected to the side wall of the clamping tooth block 406, and one end of the adjustment pin 412 passes through the vertical groove 411 and is slidably connected to the inside of the corresponding oblique groove 410. It should be noted that: since the engaging tooth block 406 is vertically slidingly arranged inside the movable groove 405, and the adjusting pin 412 is fixedly connected to the side wall of the engaging tooth block 406 and movably arranged inside the vertical groove 411, the adjusting pin 412 can only slide vertically with the engaging tooth block 406. When the adjusting plate 409 and the oblique groove 410 move to the left inside the adjusting groove 408, the adjusting pin 412 cooperates with the oblique groove 410 to slide, so that the adjusting pin 412 moves vertically with the engaging tooth block 406 inside the movable groove 405. Therefore, in the process of pulling the adjusting plate 409 to slide inside the adjusting groove 408, the oblique groove 410 on the adjusting plate 409 cooperates with the adjusting pin 412 to slide, so that the adjusting pin 412 moves along the trajectory of the vertical groove 411 with the engaging tooth block 406 inside the movable groove 405. At this time, the engaging tooth block 406 can be released from the engagement with the engaging tooth plate 402.

[0048] In this embodiment, Figures 1 to 13 As shown, the inner wall of the adjustment groove 408 is symmetrically provided with guide holes, the side wall of the adjustment plate 409 is symmetrically fixedly connected with guide rods, the two guide rods are respectively slidably connected to the inside of the two guide holes, and the middle part of the adjustment plate 409 is fixedly connected with a pull ring.

[0049] In this embodiment, Figures 1 to 13 As shown, the teeth of the engaging tooth plate 402 are triangular, and the end of the engaging tooth block 406 is wedge-shaped to match the engaging tooth plate 402. It should be noted that the wedge-shaped engaging tooth block 406 cooperates with the teeth of the engaging tooth plate 402, facilitating the engaging tooth plate 402 to be inserted into the engaging groove 404 of the clamping sleeve 403 and to engage with the engaging tooth block 406 for position locking.

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

[0051] The inner wall of the main arc-shaped positioning groove 501 is provided with a movable groove 503 that cooperates with the slide groove 2. The surface of the main arc-shaped positioning rod 502 is symmetrically fixedly connected with a positioning block 504. The positioning block 504 is slidably connected to the inside of the corresponding movable groove 503. The side wall of the support bar 3 is provided with a positioning slot 505 that cooperates with the positioning block 504. It should be noted that when the main arc-shaped positioning rod 502 slides inside the movable groove 503 with the positioning block 504, the positioning block 504 passes through the movable groove 503 and is inserted into the positioning slot 505 on the side wall of the support bar 3 to limit the support bar 3; and the inner wall of the positioning slot 505 is provided with a chamfer that cooperates with the positioning block 504 to facilitate the insertion of the positioning block 504. There are multiple positioning slots 505 and they are evenly spaced and 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, and a main arc sleeve 507 is fixedly connected to the right side of the front end of the hoop sleeve 1. The main arc sleeve 507 is slidably connected to the inside of the main arc sleeve 507. The two ends of the main pressure rod 508 correspond one-to-one to the ends of the two main arc-shaped positioning rods 502, and a return spring 509 is movably connected between the middle part of the main pressure rod 508 and the inner wall of the main arc 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 to 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 disposed 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 opposing sides of the four arc-shaped clamping plates 511 are made of rubber material and are arranged in a ring-shaped manner around the hoop sleeve 1.

[0054] Rectangular grooves 513 are symmetrically provided on both sides of the hoop sleeve 1, and a rectangular bar 514 is slidably connected inside the rectangular groove 513. The four rectangular bars 514 correspond one to one with the four arc-shaped splints 511. One end of the rectangular bar 514 passes through the rectangular groove 513 and is fixedly connected to the side wall of the corresponding arc-shaped splint 511. The surface of the rectangular bar 514 is fixedly connected to an oblique clamping plate 515.

[0055] Both sides of the hoop sleeve 1 are provided with an arc-shaped positioning groove 516, which is connected to the two rectangular grooves 513 on the same side. An arc-shaped positioning rod 517 is slidably connected to the inside of the arc-shaped positioning groove 516. A latch 518 is symmetrically fixedly connected to the top of the arc-shaped positioning rod 517. The two latches 518 correspond to the two rectangular grooves 513 one by one. The upper part of the latch 518 is engaged with the position of the oblique clamping plate 515 on the surface of the rectangular bar 514. It should be noted that: the oblique clamping plate 515 is provided in multiple and equidistantly fixed to the surface of the corresponding rectangular bar 514. When the arc-shaped positioning rod 517 moves with the latch 518, the latch 518 slides in conjunction with the inclined surface of the oblique clamping plate 515, causing the oblique clamping plate 515 to move a short distance with the rectangular bar 514 and the arc clamping plate 511, so that the arc clamping plate 511 can be further clamped and positioned. And because the arc splint 511 slides on the inner wall position of the hoop sleeve 1 through the support rod 510 and the return spring 512, the four arc splints 511 inside the hoop sleeve 1 can be freely adjusted according to the different thicknesses of the patient's limbs. When the hoop sleeve 1 is clamped on the surface of the patient's limb, the return spring 512 presses the arc splint 511 to fit the surface of the patient's limb. When the two sides of the hoop sleeve 1 are about to be engaged, the slave arc positioning rod 517 brings the bayonet pin 518 to be engaged with the inside of the oblique clamping plate 515, and at the same time, the main arc positioning rod 502 brings the positioning block 504 to be engaged with the inside of the positioning slot 505 to complete the corresponding locking.

[0056] A pressing spring 519 is movably connected between the end of the arc-shaped positioning rod 517 away from the rectangular bar 514 and the inner wall of the arc-shaped positioning groove 516, and the right side of the front end of the hoop sleeve 1 is fixedly connected to the arc-shaped sleeve 520, and the inside of the arc-shaped sleeve 520 is slidably connected to the slave pressure rod 521. The two ends of the slave pressure rod 521 correspond one-to-one to the ends of the two arc-shaped positioning rods 517, and a restoring spring 522 is movably connected between the middle of the pressure rod 521 and the inner wall of the arc-shaped sleeve 520. It should be noted that: a disc is provided at the end of the slave arc positioning rod 517, which is located at one end of the pressing spring 519. When the pressing spring 519 is in the process of elastic recovery, since one end of the pressing spring 519 is restricted to the inner wall position of the slave arc positioning groove 516, the other end of the pressing spring 519 will push the disc and the slave arc positioning rod 517 to move toward the slave arc sleeve 520. Similarly, the main arc positioning rod 502 and the slave arc positioning rod 517 have the same reset method.

[0057] In this embodiment, Figures 1 to 13As shown, the middle parts of the main pressure rod 508 and the slave pressure rod 521 are fixedly connected with a positioning ring, and the main pressure rod 508 and the slave pressure rod 521 are respectively arranged at the top and bottom of the clamping mechanism 4. It should be noted that: due to the positioning ring, 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 sleeve 507. When the two sides of the front end of the hoop sleeve 1 are fitted and locked together, the left end of the main pressure rod 508 first contacts the main arc 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 can no longer press the corresponding main arc positioning rod 502 to move, as the two sides of the front end of the hoop sleeve 1 continue to fit together, the right end of the main pressure rod 508 contacts the adjacent main arc positioning rod 502, causing the main arc positioning rod 502 on the right side of the inner wall of the hoop sleeve 1 to be compressed and moved; similarly, the use of the slave pressure rod 521 and the slave arc sleeve 520 is consistent with the above.

[0058] In this embodiment, Figures 1 to 13 As shown, the hoop sleeve 1 is composed of two arcuate plates, and the ends of the two arcuate plates are hingedly mounted. It should be noted that the hoop sleeve 1 can be opened and closed under the cooperation of the two arcuate sleeves and the clamping mechanism 4.

[0059] In this embodiment, Figures 1 to 13 As shown, a method for using a fixation device for field fracture emergency treatment includes the following steps:

[0060] S1. When in use, first place the two hoop sleeves 1 in the open state at the two ends of the patient's fracture, 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 position of the front end of the hoop sleeve 1 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;

[0061] S2. When the hoop sleeve 1 is wrapped around the surface of the patient's limb, under the action of the return spring 512, the arc-shaped splint 511 on the inner wall of the hoop sleeve 1 can freely press against the surfaces of limbs 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 on the right side of the front end of the hoop sleeve 1 both move to 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 the main arc positioning rod 502 inside the main arc positioning groove 501, so that the main arc positioning rod 502 is brought into contact with the patient. The fixedly connected positioning block 504 is inserted into the side wall position of the support bar 3 at the position of the slide groove 2, and is plugged into the positioning slot 505 on the side wall of the support bar 3 to lock the position of the support bar 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 of the hoop sleeve 1, locking the support bar 3 at the right side 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, limiting the distance between the two hoop sleeves 1;

[0062] 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 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 presses against the end face of the corresponding slave arc positioning rod 517, so that the slave arc positioning rod 517 moves with the fixedly connected bayonet 518 to the position of the oblique clamping plate 515 on the surface of the corresponding rectangular strip 514. During the movement, the pressing rectangular bar 514 moves a short distance with the arc-shaped splint 511 toward the surface of the patient's limb. Similarly, when the left end of the arc-shaped positioning rod 517 moves to the extreme position, the arc-shaped positioning rod 517 moves rightward relative to the arc-shaped sleeve 520 and presses against the arc-shaped positioning rod 517 on the right side of the hoop sleeve 1. At this point, 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 in the current position.

[0063] S4. Finally, when the hoop sleeve 1 needs to be loosened, the adjusting plates 409 on the two hoop sleeves 1 are pulled so that the inclined groove 410 on the adjusting plate 409 cooperates with the adjusting pin 412 to slide. 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 releases the clamping state with the engaging tooth plate 402, and the hoop sleeve 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 unlocked, and the hoop sleeve 1 can be removed.
