Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of bone setting equipment, and in particular to a bone setting auxiliary support device. Background Art
[0002] Fracture refers to a complete or partial break in the continuity of the bone structure. It is one of the common diseases in orthopedics, and limb fractures are the most common among clinical fracture patients. When performing bone setting operations, medical staff first need to reposition, dock and fix the two ends of the patient's fracture site. Manual docking and reduction are labor-intensive and the docking effect is difficult to guarantee. Therefore, auxiliary bone setting devices have appeared on the market.
[0003] For example, patent No. CN202010083884.7 "An auxiliary alignment device for limb fracture docking" includes a bottom frame, a telescopic rod, a lifting plate, a top plate, a T-shaped slide rail, a T-shaped slide cylinder, an adjusting rod, a lifting screw, a locking screw, an arc-shaped support plate, a semicircular support plate, a locking threaded cylinder, etc. It mainly drives the nut to move through the screw, and the limb is fixed to the nut by means of a support plate, thereby realizing operations such as stretching or docking the patient's limbs.
[0004] In actual use, nuts are generally assembled on the screw rod in the early stage of manufacturing, and it is not convenient to increase or decrease the number of nuts in the later stage. However, the number of nuts required to fix and support the limbs varies depending on the patient's limb length, fracture site and number of fractures. If too many nuts are set on the screw rod, it will be inconvenient to use during bone setting. If the number of nuts set is insufficient, it cannot meet the needs of bone setting. Summary of the invention
[0005] In view of the deficiencies of the above-mentioned technology, the purpose of the present invention is to provide a bone-setting auxiliary support device to solve the problem that the bone-setting auxiliary device designed with a screw and nut in the prior art is difficult to add and reduce the nut on the screw at a later stage, resulting in such bone-setting auxiliary device being unable to meet the needs of bone-setting use.
[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:
[0007] A bone setting auxiliary support device comprises a mounting platform, at least one set of hydraulic rods are symmetrically arranged at both ends of the mounting platform in the length direction, the output ends of the hydraulic rods are vertically upward, and mounting plates are arranged thereon, mounting blocks are arranged at both ends and the middle of the mounting plate, screw rods and smooth rods are respectively arranged on the mounting blocks located in the middle and on both sides of the mounting plate, the two ends of the screw rods and the smooth rods are respectively rotatably connected to the upper ends of the mounting blocks, the screw rods are provided with two sets of nuts with opposite thread rotation directions, the nuts are composed of a symmetrically arranged left half nut and a right half nut, and the left half nut and the right half nut are detachably connected by bolts Connection, a limit rod is provided on the side of the left half nut and the right half nut facing the light rod, one end of the limit rod is clamped on the nut, and the other end of the limit rod is slidably connected to the light rod, and a sleeve for clamping the limb is provided on the side of the nut away from the mounting platform, the sleeve includes a support sleeve and a clamping sleeve, the clamping sleeve is fixedly connected to the inner side surface of the support sleeve, and a left fixing plate and a right fixing plate are provided between the outer side surface of the support sleeve and the nut, one end of the left fixing plate and the right fixing plate are connected to the outer side surface of the support sleeve, and the other end is detachably connected to the left half nut and the right half nut respectively.
[0008] The working principle of this technical solution is as follows:
[0009] Medical staff fix the patient's limbs on the clamping sleeves set on the nuts with opposite rotation directions. By rotating the screw, the nut is limited by the rotation of the bare rod, so the nut can move away from or towards each other on the screw, thereby stretching and docking the patient's limbs. Secondly, in this technical solution, the nut consists of a left half nut and a right half nut, and adopts a split setting, so that the nut can be quickly increased and decreased according to usage needs in the later stage, thereby improving the support and auxiliary effects during bone setting.
[0010] The locking plate is configured to lock the support frame and the support frame in a manner that the locking plate is fixed to the support frame and is in a position to lock the support frame in the locking position.
[0011] It is further defined that the screw and the light rod are both provided with a fracture at the same position, and a first connecting block and a second connecting block are provided in the fracture, one end of the first connecting block and the second connecting block are respectively fixedly connected to the two ends of the fracture, and the other end of the first connecting block is rotatably connected to the other end of the second connecting block. The advantage of setting the fracture is that the screw and the light rod at both ends of the fracture can be rotated up and down independently, and the two ends of the patient's fractured limb are respectively fixed to the clamping sleeves at both ends of the fracture, that is, by raising or lowering the height of one side of the hydraulic rod, the inclination angle of the broken bone at the fracture site can be adjusted, so that the broken bones at both ends of the fracture site can be restored to a normal angle.
[0012] It is further defined that support mechanisms are provided on both sides of the fracture of the screw rod and the light rod, and the support mechanisms include a top block, an inner support rod and an outer support rod. One end of the top block and the inner support rod are rotatably connected, and the other end is respectively in contact with the screw rod and the light rod, and the inner support rod and the outer support rod are threadedly connected. The advantage of this is that the inner support rod and the outer support rod are threadedly connected, and the height can be adaptively adjusted according to the inclination angle of the screw rod to support the fracture.
[0013] It is further defined that a slideway and a slider are provided on the mounting platform, one end of the outer support rod is fixedly connected to the slider, and the moving direction of the slider is parallel to the axial direction of the bolt. The advantage is that the support position at different fractures can be adjusted according to the movement to improve the support effect.
[0014] It is further defined that the contact end of the top block with the screw rod and the smooth rod is provided with an arc shape adapted to the shapes of the two, which is beneficial in that the supporting effect is improved.
[0015] It is further defined that the hydraulic rod is slidably connected to the mounting platform, and the sliding direction is perpendicular to the axial direction of the screw. Its advantage is that the position of the broken bone can be adjusted by sliding left and right. It is not difficult to understand that at this time, medical personnel need to fix one end of the limb and fix the other end of the limb on the clamping sleeve for use.
[0016] It is further defined that the bare rod is arranged below the screw rod, which is beneficial in that it reduces the occupied area of the upper operating space and frees up more space for bone setting operations.
[0017] It is further defined that a rocker is provided on one end of the screw rod for facilitating the rotation of the screw rod, which has the advantage of facilitating the rotation of the screw rod and saving more effort.
[0018] It is further defined that through holes are provided on the parts of the left half nut and the right half nut that are connected to the ends of the limiting rod, and the limiting rod is a telescopic rod. When the ends of the telescopic rod are located in the through holes, the rotation of the nut is limited. The advantage is that such a setting method can further improve the efficiency and effect of nut installation and disassembly after the nut is installed on the screw rod. Compared with the setting method in which the ends of the limiting rod are fixed on the nut, this method will not cause interference during installation, and installation is easier. It is not difficult to understand that the inner rod and the outer rod are sleeved on the telescopic rod, and a compression spring is provided inside.
[0019] The technical effects achieved by the present invention are as follows:
[0020] (1) The nut is set in a split type, so that the nut can be quickly added or removed on the screw rod according to the use requirements in the later stage, thereby improving the support and auxiliary effect during bone setting. (2) The setting of the screw rod and the bare rod fracture allows the screw rod and the bare rod at both ends of the fracture to rotate up and down independently, that is, by raising or lowering the height of the hydraulic rod on one side, the inclination angle of the fractured bone can be adjusted, so that the fractured bones at both ends of the fractured bone can be reset to a normal angle, solving the problem that the fractured bone is difficult to reset manually during manual reset. (3) Through holes are set on the left half nut and the right half nut, and the limit rod is set as a telescopic rod. After the nut is installed and fixed, the limit rod can be installed, further improving the efficiency and effect of nut installation and removal. (4) The support sleeve is slidably connected in the through groove, that is, the support sleeve can realize rotational movement, and the position of the support sleeve can be limited by the limit pin, that is, the patient's twisted fracture site can be reset and fixed by means of a rotating part, which is convenient for later bone setting operations.

DETAILED DESCRIPTION
[0029] The following is further described in detail through specific implementation methods:
[0030] like Figure 1-Figure 6 As shown, a bone setting auxiliary support device comprises a mounting platform 1, at least one group of hydraulic rods 2 are symmetrically arranged at both ends of the mounting platform 1 in the length direction. It should be noted that the hydraulic rods 2 here can be manual or automatic. In order to achieve precise control, it is preferably set as a manual hydraulic rod 2 here, which is lifted and lowered in a manner similar to a jack. Of course, it can also be a linear push rod, etc. The output ends of the hydraulic rods 2 are vertically upward, and mounting plates 3 are arranged thereon. Both ends and the middle of the mounting plate 3 are provided with vertically arranged mounting blocks 4. A screw rod 6 is arranged in the middle of the mounting plate 3, and a plurality of light rods 5 are arranged on both sides. The screw 6 and the two ends of the light rod 5 are rotatably connected to the upper ends of the mounting blocks 4 respectively. It is not difficult to understand here that the rotation connection can be achieved through bearings, and the ends need to be limited to avoid lateral disengagement. The screw 6 is provided with two groups of screws A nut with opposite thread rotation directions, the nut consists of a symmetrically arranged left half nut 8 and a right half nut 7, the left half nut 8 and the right half nut 7 are detachably connected by bolts, and a limit rod 9 is provided on the side of the left half nut 8 and the right half nut 7 facing the light rod 5, one end of the limit rod 9 is clamped on the nut, and the other end of the limit rod 9 is slidably connected to the light rod 5, and a sleeve for clamping the limb is provided on the side of the nut away from the mounting platform 1, the sleeve includes a support sleeve 12 and a clamping sleeve 24, the clamping sleeve 24 is fixedly connected to the inner side surface of the support sleeve 12, and a left fixing plate and a right fixing plate 10 are provided between the outer side surface of the support sleeve 12 and the nut, one end of the left fixing plate and the right fixing plate 10 are connected to the outer side surface of the support sleeve 12, and the other end is detachably connected to the left half nut 8 and the right half nut 7 respectively.
[0031] The working principle of this technical solution is as follows:
[0032] The medical staff fixes the patient's limbs on the clamping sleeve 24 set on the nut with opposite rotation direction, and rotates the screw 6. Since the nut is limited by the rotation of the light rod 5, the nut will move away from or towards each other on the screw 6, thereby stretching and docking the patient's limbs. Secondly, in the present technical solution, the nut is composed of a left half nut 8 and a right half nut 7, and a split setting is adopted, so that the nut can be quickly increased and decreased according to the use requirements in the later stage, thereby improving the support and auxiliary effects during bone setting.
[0033] A through groove 11 is provided on one end of the left fixing plate and the right fixing plate 10 connected to the support sleeve 12, and the support sleeve 12 is slidably connected to the through groove 11. In the present specific embodiment, the support sleeve 12 is arc-shaped, and a plurality of evenly distributed first limiting holes 13 are provided on one side surface of the support sleeve 12. Second limiting holes 13 are provided on the side surfaces of the left fixing plate and the right fixing plate 10 outside the first limiting holes 13. A limiting pin 14 and a limiting spring 15 sleeved on the limiting pin 14 are provided on the outside of the second limiting hole 13. One end of the limiting pin 14 is located in the second limiting hole 13 and the first limiting hole 13. The limiting pin 14 The other end is fixedly connected to the limit spring 15, and the other end of the limit spring 15 is fixed to the outside of the second limit hole 13. The support sleeve 12 is slidably connected to the through groove 11, that is, the support sleeve 12 can realize rotational movement, and the position of the support sleeve 12 can be limited by the limit pin 14. Then, according to the fracture condition of the patient's limb, the fracture site twisted by the patient can be reset and fixed by the rotating member, which is convenient for the later bone setting operation. At the same time, the setting of the limit spring 15 makes the limit pin 14 not easy to fall out. It is not difficult to understand that the clamping sleeve 24 can be an airbag clamping or a strap clamping.
[0034] The screw rod 6 and the light rod 5 are both provided with a fracture at the same position, and a first connecting block 16 and a second connecting block 17 are provided in the fracture. One end of the first connecting block 16 and the second connecting block 17 are respectively fixedly connected to the two ends of the fracture, and the other end of the first connecting block 16 is rotatably connected to the other end of the second connecting block 17 through a rotating shaft 18. The advantage of setting the fracture is that the screw rod 6 and the light rod 5 at both ends of the fracture can be rotated up and down independently, and the two ends of the patient's fractured limb are respectively fixed to the clamping sleeves 24 at both ends of the fracture, that is, by raising or lowering the height of one side of the hydraulic rod 2, the inclination angle of the broken bone at the fracture site can be adjusted, so that the broken bones at both ends of the fracture site are restored to a normal angle.
[0035] Support mechanisms are provided on both sides of the fracture of the screw rod 6 and the light rod 5, and the support mechanisms include a top block 21, an inner support rod 19 and an outer support rod 20. One end of the top block 21 and the inner support rod 19 is rotatably connected, and the other end is in contact with the screw rod 6 and the light rod 5 respectively. The inner support rod 19 and the outer support rod 20 are threadedly connected. The inner support rod 19 and the outer support rod 20 are threadedly connected, and the height can be adaptively adjusted according to the inclination angle of the screw rod 6 to support the fracture.
[0036] The mounting platform 1 is provided with a slideway 23 and a slider 22. One end of the outer support rod 20 is fixedly connected to the slider 22, and the moving direction of the slider 22 is parallel to the axial direction of the bolt. The support position at different fractures can be adjusted according to the movement to improve the support effect. The contact end of the top block 21, the screw rod 6 and the polished rod 5 is provided with an arc shape that matches the shape of the two to improve the support effect.
[0037] The hydraulic rod 2 is slidably connected to the mounting platform 1, and the sliding direction is perpendicular to the axial direction of the screw 6. The position of the fractured bone can be adjusted by sliding left and right. It is not difficult to understand that at this time, the medical staff needs to fix one end of the limb, and the other end of the limb is fixed on the clamping sleeve 24 for use. The light rod 5 is arranged below the screw 6 to reduce the occupied area of the upper operating space and free up more space for bone setting operation. A rocker is provided at one end of the screw 6 to facilitate the rotation of the screw 6, which is convenient for rotating the screw 6 and more labor-saving.
[0038] Through holes are provided on the parts of the left half nut 8 and the right half nut 7 that are connected to the ends of the limit rod 9. The limit rod 9 is a telescopic rod. When the end of the telescopic rod is located in the through hole, the rotation of the nut is limited. This arrangement allows the nut to be installed on the screw rod 6 before the limit rod 9 is installed, thereby further improving the efficiency and effect of nut installation and disassembly. Compared with the arrangement in which the end of the limit rod 9 is fixed to the nut, this arrangement does not cause interference during installation, and installation is easier. It is not difficult to understand that the inner rod and the outer rod are sleeved on the telescopic rod, and a compression spring is provided inside.
[0039] It should be noted in advance that, in the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
