Description

Technical Field

[0001] This utility model relates to the field of orthopedic treatment technology, specifically to a separate and adjustable bone-setting device. Background Technology

[0002] A rib fracture is a fracture of the rib caused by external force. It is commonly seen in traffic accidents, falls, sports injuries, or other traumas. In some cases, such as when the fracture leads to serious complications, surgical fixation is required. Generally, metal plates and screws are used for fixation.

[0003] For example, Chinese patent application CN117355283A discloses a rib fixation plate or rib guard plate, including a support plate and a buffer pad. The support plate has a concave-convex structure on the surface that mates with the buffer pad. The buffer pad integrally has a central part and a peripheral U-shaped cross-section. The central part of the buffer pad is embedded into the concave-convex structure of the support plate by injection molding, and the peripheral U-shaped cross-section of the buffer pad covers the periphery of the support plate.

[0004] However, when using this rib fixation plate or rib guard, the two ends of the broken rib need to be clamped and aligned first. Since the rib is relatively fragile, the clamping and alignment process may cause rib damage, which may affect the pleura and cause pneumothorax.

[0005] Based on this, the present invention designs a separate adjustable bone setting device to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a separate adjustable bone setting device.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A separate adjustable bone setting device includes a bone fixation component and an adjustable spreading component;

[0009] The bone fixation assembly includes a detachable bone fixation component and a fixation component for locking after bone fixation;

[0010] Two separate bone-setting components are symmetrically arranged on the left and right sides. Each separate bone-setting component includes a circumferential structure with a bending structure. A fixing component and an adjustable spreading component are installed on the circumferential structure.

[0011] Furthermore, the circumferential structure includes a bone plate and circumferential arms. Two circumferential arms are symmetrically arranged on the front and rear sides of the bone plate. The bone plate and circumferential arms are semi-arc-shaped. The bone plate and circumferential arms have bending structures. The bone plate is connected to the fixing component and the adjustable spreading component.

[0012] Furthermore, the bending structure consists of a bending strip groove and a bending circular groove, with a corresponding bending strip groove on the circumferential arm and a bending circular groove on the upper end of the bone plate.

[0013] Furthermore, the detachable bone graft component also includes screws, with two screws arranged side by side. The screws are threaded onto the upper end of the bone graft plate, and the bone graft plate has fixing holes corresponding to the screws.

[0014] Furthermore, the fixing component includes a connecting threaded seat, a threaded rod, and a nut. There are two connecting threaded seats and nuts. The two connecting threaded seats are respectively fixedly installed on one side of the two bone plates. The threaded rod is threadedly connected to the two connecting threaded seats. The two nuts are sleeved on the outside of the threaded rod and threadedly connected to the threaded rod. The two nuts are respectively located on both sides of one connecting threaded seat.

[0015] Furthermore, the adjustable spreading assembly includes a floating component and a spreading component. Two floating components are provided for each of the two bone plates. The floating components are installed on one side of the bone plate and connected to the spreading component.

[0016] Furthermore, the floating component includes a connecting floating seat and a floating connecting block. The connecting floating seat is fixedly installed on one side of the bone plate. The inner side of the connecting floating seat is provided with a groove to cooperate with the floating connecting block. One end of the floating connecting block is located inside the groove of the connecting floating seat and is rotatably connected to the connecting floating seat. The other end of the floating connecting block is connected to the spreading component.

[0017] Furthermore, the spreading component includes a rack, a sliding frame, a gear, and a mounting block. The mounting block is fixedly connected to one end of the rack. The mounting block and the sliding frame have grooves for engaging floating connecting blocks. One end of the floating connecting block on the left is located in the groove of the mounting block and is rotatably connected to the mounting block. One end of the floating connecting block on the right is located in the groove of the sliding frame and is rotatably connected to the sliding frame.

[0018] Furthermore, the front and rear ends of the floating connecting block are cylindrical, and the grooves connecting the floating seat, the mounting block and the sliding frame are correspondingly cylindrical, with the opening side of the groove gradually expanding from the inside to the outside.

[0019] Furthermore, the opening component also includes a knob, with one end of the gear fixedly connected to the knob.

[0020] Compared with the prior art, the advantages of this utility model are as follows: 1. By setting two separate bone-setting components and cooperating with the adjustable spreading component to adjust the distance between the two separate bone-setting components, it is possible to align and fix the ribs after wrapping around both sides of the fractured ribs, avoiding direct clamping of the ribs for position adjustment, which would cause the relatively fragile ribs to be damaged under clamping action, thereby damaging the pleura and causing pneumothorax. It also reduces the difficulty of operation for doctors.

[0021] 2. By using threaded rods and nuts, the two bone plates are locked after the two ends of the fractured rib are aligned, thus fixing the rib and preventing the two bone plates from shifting and causing the rib to become misaligned, which would reduce the treatment effect. The screws further improve the tightness of the bone plates and the rib.

[0022] 3. The floating seat and floating connecting block allow the two bone plates to be relatively misaligned, which is used to hug the misaligned ribs when they overlap. At the same time, it can protect the rack and prevent the rack from bending and being damaged due to different angles when the two bone plates are spread apart. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0034] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 A separate adjustable bone-setting device includes a bone-fixing component 1 and an adjustable spreading component 2.

[0035] The bone fixation assembly 1 includes a detachable bone fixation component 11 and a fixation component 12 for locking after bone fixation;

[0036] Two separate bone-setting components 11 are symmetrically arranged on the left and right sides. Each separate bone-setting component 11 includes a circumferential structure with a bending structure. The bending structure facilitates the deformation of the circumferential structure to fix the rib. A fixing component 12 and an adjustable spreading component 2 are installed on the circumferential structure.

[0037] In normal use, the two separate bone-setting components 11 are fixed to both ends of the fractured rib. The adjustable spreading component 2 is used to adjust the distance between the two separate bone-setting components 11 so that the fracture ends of the fractured rib are aligned and do not overlap. The fixing component 12 is used to fix the two separate bone-setting components 11, thereby completing the bone-setting process of the fractured rib. By setting up two separate bone-setting components 11 and adjusting the distance between them with the adjustable spreading component 2, the rib can be aligned and fixed after wrapping around both sides of the fractured rib. This avoids directly clamping the rib for position adjustment, which could damage the fragile rib under clamping and cause pneumothorax. It also reduces the difficulty of operation for doctors.

[0038] Example 2: In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, in a preferred embodiment of the present invention, the circumferential structure includes a bone plate 111 and circumferential arms 112. Two circumferential arms 112 are symmetrically arranged on the front and rear sides of the bone plate 111. The bone plate 111 and the circumferential arms 112 are semi-arc-shaped. The bone plate 111 and the circumferential arms 112 are provided with bending structures. The bone plate 111 is connected to the fixing component 12 and the adjustable spreading component 2.

[0039] The bending structure consists of a bending strip groove 113 and a bending circular groove 114. The bending strip groove 113 is correspondingly provided on the circumferential arm 112, and the bending circular groove 114 is provided at the upper end of the bone plate 111.

[0040] The detachable bone-setting component 11 also includes screws 116. Two screws 116 are arranged on the left and right sides. The screws 116 are threaded onto the upper end of the bone plate 111. The bone plate 111 has fixing holes 115 corresponding to the screws 116. The screws 116 are flat-head screws.

[0041] The fixing component 12 includes a connecting threaded seat 121, a threaded rod 122, and a nut 123. There are two connecting threaded seats 121 and nuts 123. The two connecting threaded seats 121 are respectively fixedly installed on one side of the two bone plates 111. The threaded rod 122 is threadedly connected to the two connecting threaded seats 121. The two nuts 123 are sleeved on the outside of the threaded rod 122 and threadedly connected to the threaded rod 122. The two nuts 123 are respectively located on both sides of one connecting threaded seat 121.

[0042] A protrusion is fixedly provided on the side of the threaded rod 122 away from the nut 123 and is in contact with the connecting threaded seat 121. The protrusion of the threaded rod 122 cannot pass through the inner through groove of the connecting threaded seat 121.

[0043] In normal use, the bone plate 111 is placed in sterile ice-salt water for cooling. Then, the circumferential arm 112 is unfolded using a spreader. The bent strip groove 113 and the bent circular groove 114 facilitate the unfolding of the circumferential arm 112. The bone plate 111 and the circumferential arm 112 are then fitted against the fractured rib. The bone plate 111 and the circumferential arm 112 are rinsed with sterile hot saline. The bone plate 111 and the circumferential arm 112 are restored to their original shape, completing the rib circumferential fixation. The distance between the two separate bone-setting components 11 is adjusted using the adjustable spreader assembly 2 to move the rib, aligning the two ends of the fractured rib. The threaded rod 122 is inserted into the connecting threaded seat 121, and then... Two nuts 123 are used to fix a connecting threaded seat 121, thereby locking the two bone plates 111. Screws 116 are used to pass through the fixing hole 115 to further lock the bone plates 111 and the rib. The setting of the bent strip groove 113 and the bent circular groove 114 facilitates the unfolding of the bone plates 111 and the circumferential arm 112. The setting of the threaded rod 122 and the nut 123 allows the two bone plates 111 to be locked after the two ends of the fractured rib are aligned, thereby fixing the rib and preventing the two bone plates 111 from being misaligned and causing the rib to be misaligned, which would reduce the treatment effect. The screw 116 further improves the tightness of the bone plates 111 and the rib.

[0044] Example 3: In some embodiments, such as Figures 1-6 As shown, in a preferred embodiment of the present invention, the adjustable spreading component 2 includes a floating component 21 and a spreading component 22. Two floating components 21 are provided corresponding to two bone plates 111. The floating components 21 are installed on one side of the bone plate 111 and connected to the spreading component 22.

[0045] The floating component 21 includes a connecting floating seat 211 and a floating connecting block 212. The connecting floating seat 211 is fixedly installed on one side of the bone plate 111. The inner side of the connecting floating seat 211 is provided with a groove to cooperate with the floating connecting block 212. One end of the floating connecting block 212 is located inside the groove of the connecting floating seat 211 and is rotatably connected to the connecting floating seat 211. The other end of the floating connecting block 212 is connected to the spreading component 22.

[0046] The spreading component 22 includes a rack 221, a sliding frame 222, a gear 223, and a mounting block 225. The mounting block 225 is fixedly connected to one end of the rack 221. The mounting block 225 and the sliding frame 222 have grooves that cooperate with the floating connecting block 212. One end of the floating connecting block 212 on the left is located in the groove of the mounting block 225 and is rotatably connected to the mounting block 225. One end of the floating connecting block 212 on the right is located in the groove of the sliding frame 222 and is rotatably connected to the sliding frame 222. The sliding frame 222 is slidably connected to the rack 221. The gear 223 is rotatably mounted on the sliding frame 222 and meshes with the rack 221.

[0047] The front and rear ends of the floating connecting block 212 are cylindrical, and the slots connecting the floating seat 211, the mounting block 225 and the sliding frame 222 are correspondingly cylindrical, with the opening side of the slot gradually expanding from the inside to the outside.

[0048] The opening component 22 also includes a knob 224, and one end of the gear 223 is fixedly connected to the knob 224.

[0049] In normal use, the two ends of the fractured rib may overlap and therefore not be on the same horizontal plane. The two bone plates 111 rotate slightly with the floating connecting block 212 to fit the two ends of the rib. After the bone plates 111 and the circumferential arm 112 encircle the rib, the knob 224 is turned. The knob 224 drives the gear 223 to rotate. The gear 223 rotates along the rack 221, which drives the sliding frame 222 to move. The sliding frame 222 drives the corresponding bone plates 111 to move, thereby adjusting the distance between the two ends of the fractured rib. First, the two ends of the rib are separated to avoid overlap, and then the two ends of the rib are brought closer together to complete the fitting and alignment. When aligning the ribs to the same horizontal line, use threaded rod 122 and nut 123 to lock them in place. Nut 123 further reinforces the ribs, completing the rib-joining process. The rack 221, sliding frame 222, and gear 223 allow for free adjustment of the distance between the two rib plates 111, facilitating the separation and fitting of the ribs. The floating seat 211 and floating connecting block 212 allow the two rib plates 111 to be relatively misaligned, which helps to encircle the misaligned ribs when they overlap. At the same time, it protects the rack 221, preventing it from bending and being damaged due to different angles when the two rib plates 111 are spread out.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
