Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a bone transport frame. Background Art

[0002] Bone transport is a treatment method for dealing with bone defects. Specifically, it means that with the assistance of a bone transport frame, a section of bone to be traction is intercepted at the proximal or distal end of the defective bone, and a traction force is applied to the intercepted bone to be traction, and the bone to be traction is slowly pulled away from the intercepted part to stimulate bone regeneration. Eventually, new bone will regenerate between the bone to be traction and the adjacent fixed bone to achieve the purpose of filling the bone defect.

[0003] In the related art, the traction component in the bone transport frame is connected to the bone to be traction, and the positioning component is connected to the original bones on both sides of the bone to be traction. During bone transport, pressure is applied to the traction component by the pressurizing component to slowly pull the bone to be traction away from the fixed bone.

[0004] However, in the related art, over time, it is necessary to continuously manually adjust the pressure of the pressurizing component on the traction component. There are easy adjustment errors during the adjustment process, which affect the regeneration effect of the bone during bone transport. At the same time, the steps of the adjustment process are relatively cumbersome, further reducing the adjustment efficiency. Summary of the Utility Model

[0005] In view of the above problems, the embodiments of this application provide a bone transport frame, which solves the problems of large errors and cumbersome processes when manually adjusting the tensile stress of the pressurizing component, thereby improving the adjustment accuracy of the traction force applied to the bone to be traction and enhancing the bone regeneration effect.

[0006] To achieve the above object, the embodiments of this application provide the following technical solutions:

[0007] The embodiments of this application provide a bone transport frame, including: a bracket, a traction component, a positioning component, a pressurizing component, and a communication component; the traction component and the positioning component are respectively movably connected to the bracket and can move along the extension direction of the bracket; the traction component is configured to be connected to the bone to be traction, and the positioning component is configured to be connected to the fixed bone adjacent to the bone to be traction; the pressurizing component is connected between the traction component and the positioning component, and the communication component is in signal connection with the pressurizing component; the pressurizing component is configured to apply a pushing pressure to the traction component according to the pressurizing signal sent by the communication component, so that the traction component traction the bone to be traction to move.

[0008] In the bone transport frame provided by the embodiments of the present application, the communication module can receive the pressurization information from the client, and drive the pressurization component to apply a pushing pressure to the traction component according to the pressurization information, so as to remotely adjust and precisely adjust the traction force on the bone to be tractioned, eliminating the cumbersome steps of manual adjustment and further improving the regeneration effect of the bone during bone transport.

[0009] In some embodiments, the pressurization component includes a first transmission member and a second transmission member; the first transmission member is connected between the traction component and the positioning component; the second transmission member is in transmission cooperation with the first transmission member, so that the second transmission member can move relative to the first transmission member along the extension direction of the first transmission member; the second transmission member is configured to apply a pushing pressure to the traction component.

[0010] With such a setting, the second transmission member can move along the extension direction of the first transmission member. When the second transmission member moves away from the positioning component, it applies a pushing pressure to the traction component in a direction away from the positioning component, thereby applying a traction force to the bone to be tractioned in a direction away from the fixed bone, and realizing the traction and transportation of the bone to be tractioned.

[0011] In some embodiments, the first transmission member is a screw rod, and the second transmission member is a motor in transmission connection with the screw rod; one end of the screw rod away from the motor is screwed to the positioning component, so that when the motor drives the screw rod to rotate, the motor applies a pushing pressure to the traction component.

[0012] With such a setting, while the motor drives the screw rod to rotate, the screw rod can rotate relative to the positioning component, and based on the screwing connection with the positioning component, it can screw out or screw into the positioning component by a certain distance, realizing the precise adjustment of the pushing pressure received by the traction component.

[0013] In some embodiments, the traction component includes a first fixing frame and at least two traction members; the traction members are movably arranged on the first fixing frame; the pressurization component is connected between the first fixing frame and the positioning component; there is an included angle between the traction member and the bracket, and the traction member is configured to be connected to the bone to be tractioned.

[0014] With such a setting, the traction component can be stably connected to the bone to be tractioned through the traction members. Since there is an included angle between the traction members and the bracket, when the bracket is on the side of the bone, the traction component can be connected to the bone from the side of the bone, avoiding affecting the normal movement of the patient. At the same time, the fixing frame can integrate multiple traction members and adjust the relative positions of each traction member and the bracket at the same time.

[0015] In some embodiments, the first fixing bracket has an avoidance hole along the extending direction of the bracket; the traction member is configured to be located in the avoidance hole so that the traction member can rotate about the rotation axis and / or move along the extending direction under an external acting force.

[0016] With such a setting, when the traction member needs to rotate, the traction member can be restricted from moving in the avoidance hole, preventing deviation during rotation or causing interference to other components. At the same time, the avoidance hole can also play a role in guiding the movement of the traction member in the extending direction.

[0017] In some embodiments, the traction assembly further includes: a first driving member; the first driving member is connected to the traction member and is in signal connection with the communication assembly, and the first driving member is configured to drive the traction member to rotate about the rotation axis and / or move along the extending direction according to the signal sent by the communication assembly.

[0018] With such a setting, the first driving member can adjust the position of the traction member according to the signal sent by the communication assembly, thereby realizing flexible and efficient adjustment of the position of the traction member to adapt to the bone surfaces with different curvatures.

[0019] In some embodiments, the traction member includes a bone needle; the bone needle is inserted through the first fixing bracket, and one end of the bone needle is configured to be connected to the bone to be tractioned.

[0020] With such a setting, the bone needle penetrates deep into the bone to be tractioned, effectively transmitting the traction force to the bone to be tractioned. Each bone needle is inserted through the first fixing bracket, can be uniformly supported by the first fixing bracket, and realizes stable connection with the bone to be tractioned.

[0021] In some embodiments, the positioning assembly further includes a second fixing bracket and at least two fixing members, the pressing assembly is connected between the first fixing bracket and the second fixing bracket; the fixing members are movably arranged on the second fixing bracket; the fixing members are configured to be connected to the fixed bone adjacent to the bone to be tractioned.

[0022] With such a setting, the positioning assembly and the traction assembly can both be located on one side of the bone, and the two are respectively at a sufficient distance from the affected limb through the lengths of the traction member and the fixing members. And the pressing assembly applies pressure between the first fixing bracket and the second fixing bracket, which can reduce interference to the fixing members and the traction member and ensure stable connection between the fixing members and the fixed bone.

[0023] In some embodiments, the number of the positioning assemblies is two; the traction assembly is located between the two positioning assemblies; the pressing assembly is connected between one of the two positioning assemblies and the traction assembly.

[0024] With such a setting, the two positioning components can fixedly connect the bone transport rack to the bone as a whole, and determine the setting direction of the bracket and the moving direction of the bone to be traction, so as to ensure the stability of the bone transport process. At the same time, according to the actual situation, the positioning component to which the pressing component is connected can be changed to adjust the traction direction of the bone to be traction.

[0025] In some embodiments, the bone transport rack further includes a display screen, which is arranged on the positioning component and electrically connected to the communication component.

[0037] With the development of medical technology, patients with bone defects in the affected limb can achieve bone regeneration through bone transport. Alternatively, patients with tissue necrosis or damage in the affected limb can also achieve the stimulation and regeneration of tissues around the bone through bone transport. Bone transport is a treatment method for dealing with bone defects. Specifically, with the assistance of a bone transport frame, a section of bone to be tractioned is intercepted at the proximal or distal end of the defective bone, and a traction force is applied to the intercepted bone to be tractioned, slowly pulling the bone to be tractioned away from the intercepted part to stimulate bone regeneration. Eventually, new bone will regenerate between the bone to be tractioned and the adjacent fixed bone to achieve the purpose of filling the bone defect. In the related art, the traction assembly in the bone transport frame is connected to the bone to be tractioned, and the positioning assembly is connected to the original bones on both sides of the bone to be tractioned. During bone transport, a pressure is applied to the traction assembly through the pressurizing assembly, and the traction assembly applies a traction force to the bone to be tractioned to slowly pull the bone to be tractioned away from the fixed bone. However, in the related art, as the time of the bone transport treatment process progresses, it is necessary to continuously manually adjust the pressure of the pressurizing assembly on the traction assembly. There are easily adjustment errors during the adjustment process, which affect the bone regeneration effect during bone transport. At the same time, the steps of the adjustment process are relatively cumbersome, and the patient needs to go to the medical staff for adjustment multiple times, further reducing the adjustment efficiency.

[0038] To solve the above problems, the present application provides a bone transport frame, comprising: a bracket, a traction assembly, a positioning assembly, a pressurizing assembly, and a communication assembly; the traction assembly and the positioning assembly are respectively movably connected to the bracket and can move along the extending direction of the bracket; the traction assembly is configured to be connected to the bone to be tractioned, and the positioning assembly is configured to be connected to the fixed bone adjacent to the bone to be tractioned; the pressurizing assembly is connected between the traction assembly and the positioning assembly, and the communication assembly is in signal connection with the pressurizing assembly; the pressurizing assembly is configured to apply a pushing pressure to the traction assembly according to the pressurizing signal sent by the communication assembly, so that the traction assembly tractiones the bone to be tractioned to move. In this bone transport frame, the pressurizing information from the client can be received through the communication module, and the pressurizing assembly is driven according to the pressurizing information to apply a pushing pressure to the traction assembly, and the pushing pressure is transmitted to the bone to be tractioned as the traction force for the bone to be tractioned, thereby realizing the remote adjustment and precise adjustment of the traction force received by the bone to be tractioned, eliminating the cumbersome steps of manual adjustment, and further improving the regeneration effect of the bone during bone transport.

[0039] In order to make the above objects, features, and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0040] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural diagram of the bone transport frame provided by the embodiment of the present application, Figure 2 and which is a schematic structural diagram of the bone transport frame from another angle provided by the embodiment of the present application. As Figure 1 shown, the embodiment of the present application provides a bone transport frame 100, comprising: a bracket 110, a traction assembly 120, a positioning assembly 130, a pressurizing assembly 140, and a communication assembly 150; the traction assembly 120 and the positioning assembly 130 are respectively movably connected to the bracket 110 and can move along the extending direction of the bracket 110; the traction assembly 120 is configured to be connected to the bone 200 to be tractioned, and the positioning assembly 130 is configured to be connected to the fixed bone 300 adjacent to the bone 200 to be tractioned; the pressurizing assembly 140 is connected between the traction assembly 120 and the positioning assembly 130. The communication assembly 150 is in signal connection with the pressurizing assembly 140; the pressurizing assembly 140 is configured to apply a pushing pressure to the traction assembly 120 according to the pressurizing signal sent by the communication assembly 150, so that the traction assembly 120 tractiones the bone 200 to be tractioned to move.

[0041] In the bone transport rack 100 provided in the embodiment of the present application, the bracket 110 is a rigid structure with a certain length. The traction assembly 120 and the positioning assembly 130 are respectively movably connected to the bracket 110 and can change their positions along the extension direction of the bracket 110. Exemplarily, the bracket 110 can be a component extending along a straight line, and the bracket 110 passes through the traction assembly 120 and the positioning assembly 130. The traction assembly 120 or the positioning assembly 130 can actively change the relative position with the bracket 110 by sliding along the bracket 110 or by directly disassembling and reinstalling it to a different position.

[0042] In addition, the communication component 150 can be set as a receiving terminal with information processing capabilities to remotely receive instructions from the user side (such as mobile phones, computers, servers, etc.); or, the communication component 150 can also be a control panel capable of receiving offline instructions for the user to input the pressurization signal for the pressurization component 140 on-site. Whether it is a remote or offline method, the communication component 150 can adjust the pushing pressure exerted by the pressurization component 140 on the traction component 120 in real time according to the user's instructions. Exemplarily, if it is necessary to increase the pushing pressure, the communication component 150 sends a pressurization signal to the pressurization component 140; if it is necessary to decrease the pushing pressure, the communication component 150 sends a decompression signal to the pressurization component 140. The instructions input by the user to the user side or directly to the communication component 150 can be the value of the required traction force or the length that the bone 200 to be tractioned needs to move, so as to realize the precise adjustment of the traction force received by the bone 200 to be tractioned, effectively improve the regeneration effect of the bone during bone transport. At the same time, the user can adjust the traction force at any time and place without having to go to the medical staff for manual adjustment multiple times, improving the adjustment efficiency.

[0043] The pressurization component 140 is arranged between the traction component 120 and the positioning component 130, and the pressurization component 140 can change the distance between the traction component 120 and the positioning component 130 by moving or changing its own length. Exemplarily, the pressurization component 140 can be a telescopic cylinder or a hydraulic rod, and both ends of the pressurization component 140 are respectively connected to the traction component 120 and the positioning component 130. At this time, the pressurization component 140 adjusts the distance between the traction component 120 and the positioning component 130 by changing its own length to exert a pushing pressure on the traction component 120. When receiving a pressurization signal, the pressurization component 140 extends its own length; when receiving a decompression signal, it shortens its own length.

[0044] Or, as Figure 2As shown, the pressing component 140 can also be a first gear motor 141 that moves along the extending direction of the bracket 110. A first tooth groove 143 can be formed along the extending direction on the bracket 110. The pressing component 140 in the form of the first gear motor 141 can be meshed with the first tooth groove 143 through the internal first gear 142, and move along the bracket 110 by driving the first gear 142 to rotate. When the pressing component 140 abuts against the traction component 120 and moves in the direction away from the positioning component 130, a pushing pressure can be applied to the traction component 120. When receiving a pressing signal, the pressing component 140 moves in the direction away from the positioning component 130; when receiving a pressure reducing signal, the pressing component 140 moves in the direction close to the positioning component 130.

[0045] When performing bone transport using the bone transport frame 100, it is necessary to pre-cut and separate the bones in the affected limb of the patient to form a to-be-traction bone 200 that is free from the fixed bone 300. The to-be-traction bone 200 is still located inside the patient. Subsequently, the part of the positioning component 130 used to connect the fixed bone 300 penetrates the skin and muscle tissues of the affected limb and is connected to the fixed bone 300 adjacent to the to-be-traction bone 200. Subsequently, the part of the traction component 120 used to connect the to-be-traction bone 200 penetrates the skin and muscle tissues of the affected limb and is connected to the to-be-traction bone 200. After the connection is completed, the bracket 110 and the pressing component 140 are entirely located outside the patient. At this time, by adjusting the pressing component 140, a pushing pressure in the direction away from the positioning component 130 can be formed on the traction component 120, so that the traction component 120 applies a traction force in the direction away from the fixed bone 300 to the to-be-traction bone 200, driving the to-be-traction bone 200 to slowly change its position and stimulating the regeneration of new bones between the to-be-traction bone 200 and the fixed bone 300. Compared with the related art where medical staff manually adjust the pressing component 140, in the embodiment of the present application, the communication component 150 precisely adjusts or remotely adjusts the pushing pressure applied by the pressing component 140 to the traction component 120, thereby ensuring the adjustment accuracy of the traction force received by the to-be-traction bone 200 and improving the effect of bone transport.

[0046] In some embodiments, as Figure 1 shown, the pressing component 140 includes a first transmission member 144 and a second transmission member 145; the first transmission member 144 is connected between the traction component 120 and the positioning component 130; the second transmission member 145 is in transmission cooperation with the first transmission member 144, so that the second transmission member 145 can move relative to the first transmission member 144 along the extending direction of the first transmission member 144; the second transmission member 145 is configured to apply a pushing pressure to the traction component 120.

[0047] In the embodiment of the present application, as Figure 1As shown, the extending direction of the first transmission member 144 can be set to be the same as that of the bracket 110, so as to ensure that when the second transmission member 145 moves along the direction of the first transmission member 144, the pushing pressure exerted on the traction assembly 120 and the direction of the traction force received by the bone to be tractioned 200 are consistent with the extending direction of the bracket 110. Exemplarily, one end of the first transmission member 144 can be fixedly connected to the positioning assembly 130, and the other end is inserted into the second transmission member 145.

[0048] Furthermore, the second transmission member 145 can move along the extending direction of the first transmission member 144. When the second transmission member 145 moves away from the positioning assembly 130, a pushing pressure in the direction away from the positioning assembly 130 is applied to the traction assembly 120, so as to apply a traction force in the direction away from the fixed bone 300 to the bone to be tractioned 200, realizing the traction and handling of the bone to be tractioned 200.

[0049] In some embodiments, please refer to Figure 3 , Figure 3 which is a partial structural schematic diagram of another angle of the bone transport rack provided by the embodiment of the present application. As Figure 3 shown, the first transmission member 144 is a screw 1441, and the second transmission member 145 is a motor 1451 drivingly connected to the screw 1441; one end of the screw 1441 away from the motor 1451 is screwed to the positioning assembly 130, so that when the motor 1451 drives the screw 1441 to rotate, the motor 1451 applies a pushing pressure to the traction assembly 120.

[0050] In the embodiment of the present application, one end of the screw 1441 is connected to the motor 1451, and the motor 1451 can actively drive the screw 1441 to rotate. The other end of the screw 1441 is screwed to the positioning assembly 130. Obviously, while the motor 1451 drives the screw 1441 to rotate, the screw 1441 can rotate relative to the positioning assembly 130, and based on the screwing connection with the positioning assembly 130, it can be screwed out or screwed into the positioning assembly 130 by a certain distance. Exemplarily, the motor 1451 can be connected to the traction assembly 120. When the motor 1451 drives the screw 1441 to rotate, the motor 1451 and the traction assembly 120 as a whole move along the extending direction of the screw 1441, realizing fine adjustment of the distance between the traction assembly 120 and the positioning assembly 130. When the motor 1451 drives the traction assembly 120 to move away from the positioning assembly 130, this fine adjustment of the distance can enable the traction assembly 120 to receive the pushing pressure from the motor 1451, so that the bone to be tractioned 200 receives the traction force.

[0051] When the motor 1451 drives the screw 1441 to rotate, the distance to be adjusted between the positioning assembly 130 and the traction assembly 120 can be determined by the communication assembly 150 sending the number of turns to be rotated and the rotation direction to the motor 1451. The accuracy of the distance adjustment can be determined by selecting screws 1441 with different pitches or adjusting the rotation angle accuracy of the motor 1451, so as to achieve precise control of the traction force on the bone 200 to be tractioned. Among them, the screw 1441 can be integrally passed through the traction assembly 120 and the positioning assembly 130 to further guide the distance adjustment; the motor 1451 can be arranged inside the traction assembly 120, and the part of the screw 1441 exposed outside the positioning assembly 130 and the traction assembly 120 can also be sleeved with a soft protective sleeve to prevent the screw 1441 from being interfered by the surrounding environment during rotation.

[0052] In some embodiments, such as Figure 3 As shown, the traction assembly 120 includes a first fixing frame 121 and at least two traction members 122; the traction members 122 are movably arranged on the first fixing frame 121; the pressurizing assembly 140 is connected between the first fixing frame 121 and the positioning assembly 130; there is an included angle between the traction members 122 and the bracket 110, and the traction members 122 are configured to be connected to the bone 200 to be tractioned.

[0053] In the embodiments of the present application, the traction member 122 is a rigid structure with a certain length. One end of the traction member 122 is movably connected to the first fixing frame 121, and the other end is connected to the bone 200 to be tractioned. The traction assembly 120 drives the bone 200 to be tractioned to perform bone transport through the traction member 122. The first fixing frame 121 is a structure directly receiving the pushing pressure of the pressurizing assembly 140 to prevent the pushing pressure from causing too much load on the traction member 122. When there are two or more traction members 122, the traction members 122 are connected to the bone 200 to be tractioned from two or more points, which can prevent the bone 200 to be tractioned from deviating in direction or twisting itself during bone transport, and prevent the occurrence of adverse conditions of bone regeneration.

[0054] With such a setting, the traction assembly 120 can be stably connected to the bone 200 to be tractioned through the traction member 122. Since there is an included angle between the traction member 122 and the bracket 110, and the extending direction of the bracket 110 is the same as the transport direction of the bone 200 to be tractioned, the included angle between the traction member 122 and the bracket 110 can enable the traction assembly 120 to be connected to the bone from the side of the bone, avoiding affecting the normal movement of the patient. At the same time, the fixing frame can integrate multiple traction members 122 and adjust the relative positions of each traction member 122 and the bracket 110 at the same time.

[0055] In some embodiments, such as Figure 3As shown in the figure, the first fixing bracket 121 has an avoidance hole 1211 along the extending direction of the bracket 110; the traction member 122 is configured to be located in the avoidance hole 1211, so that the traction member 122 can rotate around the rotation axis and / or move along the extending direction under an external acting force.

[0056] In the embodiment of the present application, the avoidance hole 1211 is set as an elongated hole, and the traction member 122 is inserted into the avoidance hole 1211. The extending direction of the avoidance hole 1211 is set to be perpendicular to the rotation axis of the traction member 122. When the traction member 122 needs to rotate around the rotation axis, the traction member 122 can slide in the avoidance hole 1211. Furthermore, the traction member 122 can be restricted to move in the avoidance hole 1211 to prevent deviation during rotation or interference with other components.

[0057] Meanwhile, please refer to Figure 4 , Figure 4 which is a schematic structural diagram of the bone transport rack provided by the embodiment of the present application during another bone transport. As Figure 4 shown, in some bone transport situations, a free bone to be tractioned 200 needs to be cut out from the side of the affected limb bone, and the bone to be tractioned 200 is transported in the extending direction of the traction member 122 to stimulate the regeneration of the tissues around the bone. At this time, the bone transport is not achieved by changing the pushing pressure received by the traction assembly 120, but by changing the position of the traction member 122 itself to change the traction force on the bone to be tractioned 200. Therefore, the traction member 122 needs to move in its own extending direction, so that one end of the traction member 122 connected to the bone to be tractioned 200 moves towards the end away from or close to the bracket 110. Specifically, when one end of the traction member 122 connected to the bone to be tractioned 200 moves towards the end close to the bracket 110, the traction force received by the bone to be tractioned 200 is away from the fixed bone 300. Furthermore, when the traction member 122 moves along the extending direction, the avoidance hole 1211 can also play a guiding role in the movement of the traction member 122 in the extending direction.

[0058] In some embodiments, please refer to Figure 4 and Figure 5 , Figure 5 which is a schematic structural diagram of the first driving member and the traction member in the bone transport rack provided by the embodiment of the present application. The traction assembly 120 further includes: a first driving member 123; the first driving member 123 is connected to the traction member 122 and is in signal connection with the communication assembly 150. The first driving member 123 is configured to drive the traction member 122 to rotate around the rotation axis and / or move along the extending direction according to the signal sent by the communication assembly 150.

[0059] In the embodiments of the present application, the first driving member 123 is connected to the traction member 122, and it can actively drive the traction member 122 to move along the extending direction of the traction member 122. Exemplarily, as Figure 5 shown, the first driving member 123 can be in the form of a second gear motor 1231. A second tooth groove 1222 can be formed in the side wall of the traction member 122 along the extending direction, and meshing can be achieved between the second tooth groove 1222 and a second gear 1232 inside the second gear motor 1231. The second gear motor 1231 is fixedly connected to the first fixing bracket 121. When the second gear motor 1231 drives the second gear 1232 to rotate, the traction member 122 can move along the extending direction to change the traction force on the bone 200 to be tractioned or the distance into the bone 200 to be tractioned.

[0060] The communication component 150 can also send a traction instruction to the first driving member 123, so that the first driving member 123 drives the traction member 122 to move in the extending direction, thereby performing bone transport on the bone 200 to be tractioned. During this bone transport process, the pressing component 140 does not apply a pushing pressure to the traction component 120, and only the traction member 122 applies a traction force in its own extending direction to the bone 200 to be tractioned.

[0061] In addition, since the number of the traction members 122 can be multiple, and the included angles between the traction members 122 and the bracket 110 are different after the traction members 122 are connected to different bones 200 to be tractioned, the traction members 122 need to be able to rotate, and the rotation axis needs to be perpendicular to the extending direction of the traction members 122. The first driving member 123 is rotatably connected to the first fixing bracket 121 and can actively rotate. This rotation axis is the rotation axis of the traction member 122. Therefore, it is the first driving member 123 that drives the traction member 122 to adjust the angle with the bracket 110 to adapt to the bone surfaces with different curvatures.

[0062] In some embodiments, as Figure 1 shown, the traction member 122 includes a bone pin 1221; the bone pin 1221 passes through the first fixing bracket 121, and one end of the bone pin 1221 is configured to be connected to the bone 200 to be tractioned.

[0063] In the embodiments of the present application, the end of the bone pin 1221 far from the first fixing member 132 is inserted into the bone 200 to be tractioned to be fixedly connected to the bone 200 to be tractioned, so as to transfer the pushing pressure received by the traction component 120 to the bone 200 to be tractioned, or apply a traction force to the bone 200 to be tractioned through the movement of the bone pin 1221 itself. Each bone pin 1221 passes through the first fixing bracket 121 and can be uniformly supported by the first fixing bracket 121 to achieve a stable connection with the bone 200 to be tractioned.

[0064] In some embodiments, as Figure 1 shown, the positioning assembly 130 further includes a second fixing bracket 131 and at least two fixing members 132. The pressing assembly 140 is connected between the first fixing bracket 121 and the second fixing bracket 131. The fixing members 132 are movably arranged on the second fixing bracket 131. The fixing members 132 are configured to be connected to the fixed bone 300 adjacent to the bone 200 to be tractioned.

[0065] In the embodiments of the present application, the positioning assembly 130 may also include a plurality of fixing members 132. The plurality of fixing members 132 are simultaneously connected to the fixed bone 300 to prevent angular displacement of the fixed bone 300, and the position of the bracket 110 is fixed in advance before the traction member 122 is connected to the bone 200 to be tractioned. After such setting, both the positioning assembly 130 and the traction assembly 120 are located on one side of the bone, and the two are respectively at a sufficient distance from the affected limb through the traction member 122 and the fixing member 132. And the pressing assembly 140 applies a pushing pressure between the first fixing bracket 121 and the second fixing bracket 131, and the pushing pressure is transmitted to the first fixing bracket 121 and the second fixing bracket 131, which can reduce the interference with the fixing member 132 and the traction member 122 and ensure the stable connection between the fixing member 132 and the fixed bone 300. Among them, the positioning member can also be in the form of a bone pin 1221. In addition, a second driving member having the same structure as the first driving member 123 can be connected to the positioning member to drive the positioning member to rotate or move along the extending direction to stably connect to the bone surfaces with different arcs.

[0066] In some embodiments, as Figure 1 shown, the number of the positioning assemblies 130 is two. The traction assembly 120 is located between the two positioning assemblies 130. The pressing assembly 140 is connected between one of the two positioning assemblies 130 and the traction assembly 120.

[0067] In the embodiments of the present application, the two positioning assemblies 130 are respectively a first positioning assembly 131 and a second positioning assembly 132. The first positioning assembly 131 and the second positioning assembly 132 are respectively located on both sides of the traction assembly 120, and can reliably fix the whole bone transport rack 100.

[0068] Both of the two positioning components 130 can be connected to the pressurizing component 140. During the specific bone transportation process, the pressurizing component 140 can be set to be detachably connected to the traction component 120 and the pressurizing component 140. When the traction component 120 moves a sufficient distance relative to the positioning component 130 connected to the pressurizing component 140 (such as moving to the midpoint of the bracket 110), at this time, there is a certain distance between the bone 200 to be tractioned and the fixed bone 300 (proximal fixed bone 300) originally connected to the pressurizing component 140, but there is still a certain distance from the fixed bone 300 at the other end, and the bone transportation is not yet completed. Considering that the stroke of the pressurizing component 140 may be limited, at this time, the positioning component 130 connected to the pressurizing component 140 can be replaced, and the pressurizing component 140 is changed to apply a pulling force to the traction component 120, and the direction of this pulling force is the same as the direction of the original pushing and pulling force. So that the bone 200 to be tractioned continues to move towards the fixed bone 300 (distal connecting bone) connected to the positioning component 130 that was not originally connected to the pressurizing component 140, and finally is transported to the distal connecting bone and connected to it, thereby realizing bone regeneration between the proximal connecting bone and the distal connecting bone.

[0069] In some embodiments, as Figure 1 shown, the bone transportation frame 100 further includes a display screen 160, and the display screen 160 is arranged on the positioning component 130 and is electrically connected to the communication component 150.

[0070] In the embodiments of the present application, the display screen 160 can be set as a touch screen, and this display screen 160 can receive the clicks of the user to realize the adjustment of the pressurizing component 140. To avoid interfering with the traction component 120, the display screen 160 is arranged on the positioning component 130 with a fixed position. With such a setting, medical staff or patients can interact with the communication component 150 through the display screen 160, or know the magnitude, direction and adjustment suggestions of the traction force received by the bone 200 to be tractioned at this time through the display screen 160, so as to further flexibly adjust the traction force received by the bone 200 to be tractioned.

[0071] The embodiments of the present application provide a bone transportation frame, which can receive pressurization information from a client through a communication module, and drive a pressurizing component to move according to the pressurization information, so that the pressurizing component applies a pushing pressure to the traction component, thereby realizing remote adjustment and precise adjustment of the traction force received by the bone to be tractioned, eliminating the cumbersome steps of manual adjustment, and further improving the bone regeneration effect during bone transportation.
