Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to an organ box connector assembly and an organ transport platform. Background Technology

[0002] With the development of organ transplantation and organ perfusion preservation, the need for connectors that connect organs to circulatory tubing has emerged. These connectors require one end to be connected to the organ's artery or vein and the other end to the tubing, with the connection required to be well-sealed and leak-proof.

[0003] When using the above methods to preserve and transport organs, after connecting the organ to the tubing, it is necessary to expel the air from the organ. According to existing organ transport platforms, there is a risk that the air inside the organ may be pushed back into the organ by the liquid in the tubing, which is extremely detrimental to the preservation and transport of organs. Summary of the Invention

[0004] In view of the above-mentioned defects in the prior art, the purpose of the present invention is to provide an organ box connector assembly and an organ transport platform, which can effectively expel air from the organ and prevent air from being pushed back into the organ under the action of liquid.

[0005] Therefore, the present invention provides the following technical solution.

[0006] This invention provides an organ box connector assembly, the organ box connector assembly comprising:

[0007] The first connector has a pipe connector, an exhaust port for exhausting air, and a hose connection.

[0008] An intermediate connecting assembly, which is connected to the hose connection via a hose, and has a first locking element;

[0009] The second connector has one end that is plugged into the intermediate connecting component, and the other end that is used to connect to the artery or vein of the organ.

[0010] The second connector is locked to the intermediate connection assembly by the first locking member.

[0011] In at least one embodiment, the first locking member is configured to be movable between a first working position and a second working position;

[0013] In at least one embodiment, the intermediate connection component further includes a first elastic element and a first operating element, both of which are connected to the first locking element;

[0014] Specifically, operating the first operating member enables the first locking member to overcome the elastic force of the first elastic member and move to the second working position. After the external force on the first operating member is removed, the first locking member moves from the second working position to the first working position under the action of the first elastic member and remains in the first working position.

[0015] In at least one embodiment, when the second connector is disassembled in a direction opposite to the insertion direction of the second connector while the second connector is locked, the force exerted by the second connector on the first locking member is perpendicular to the direction in which the first locking member moves from the first working position to the second working position.

[0016] In at least one embodiment, the first locking member includes a first annular portion, a first connecting portion and a second connecting portion, the first connecting portion and the second connecting portion being located on both radial sides of the first annular portion, the first elastic member being sleeved on the first connecting portion, and the second connecting portion being connected to the first operating member.

[0017] The first annular portion has a first limiting plane that restricts the second connector from disengaging from the intermediate connecting assembly, and the first limiting plane is perpendicular to the insertion direction.

[0018] In at least one embodiment, the intermediate connection assembly further includes a first housing portion having a mounting guide groove, wherein the first operating member is at least partially disposed in the mounting guide groove, the mounting guide groove being capable of guiding and limiting the movement of the first operating member.

[0019] In at least one embodiment, the intermediate connection assembly further includes a first housing portion having a first chamber, and a first locking member is at least partially disposed in the first chamber, the first locking member being slidable in the first chamber to switch between a first working position and a second working position.

[0020] In at least one embodiment, the first housing portion has a connecting hole, the second connector is inserted into the connecting hole along the axial direction of the connecting hole, and the sliding direction of the first locking member is perpendicular to the axial direction of the connecting hole.

[0021] In at least one embodiment, the outer peripheral wall of the second connector is formed with a first locking groove, and the first locking member is at least partially inserted into the first locking groove in the first working position to lock the second connector.

[0022] In at least one embodiment, the outer peripheral surface of the other end of the second connector is formed with at least one annular groove, the at least one annular groove being used for connection with an artery or vein of the organ.

[0023] The present invention also provides an organ transport platform, which includes the organ box connector assembly described in any of the above embodiments.

[0024] In at least one embodiment, the hose includes a first wall structure and a second wall structure in the circumferential direction, the elastic modulus of the first wall structure is greater than that of the second wall structure, and the second wall structure can be clamped and deformed to close the fluid passage of the hose.

[0025] In at least one embodiment, the second pipe wall structure is symmetrically arranged and together with the first pipe wall structure forms the hose.

[0026] In at least one embodiment, the organ transport platform includes an organ box, and the side wall of the organ box is provided with a positioning groove.

[0027] The first connector is provided with a positioning part, and the first connector is positioned and connected to the organ box by the cooperation of the positioning part and the positioning groove.

[0028] Beneficial effects

[0029] According to the organ box connector assembly of the present invention, by providing a flexible tube between the first connector and the intermediate connecting assembly, the tube can be clamped with a pipe wrench during circuit pre-filling and venting, thereby preventing air from being pushed back into the organ under the action of liquid. The flexible tube can also adaptively adjust its bending angle according to the size of the organ, allowing organs of different sizes to be placed more smoothly in the organ box. After the organ is placed in the organ box, liquid containing air bubbles can be pushed towards the vent with a pipe wrench, allowing the air bubbles to be expelled from the vent, better removing air from the circulation pipeline and ensuring the normal operation of the circulation pipeline. Simultaneously, by using a flexible tube, when the organ box connector assembly is installed into the organ box to connect the organ, there is no need to install a bent tube to cross steps, further avoiding the risk of thrombosis at bends, thus improving the safety and reliability of organ maintenance. Finally, the intermediate connecting assembly and the second connector are plugged in, instead of the existing threaded connection, making the connection simple and convenient, avoiding the twisting and bending of the flexible tube caused by threaded connections, thereby ensuring the stability and reliability of the flexible tube installation. The flexible tube is designed with a first tube wall structure and a second tube wall structure with different elastic moduli in the circumferential direction. This makes the part with higher elastic modulus stable and less prone to shaking when the flexible tube is placed in the organ box, while the part with lower elastic modulus is easy to clamp and close the channel.

[0068] The following is based on Figures 1 to 11 Detailed description of specific embodiments of the organ box connector assembly according to the present invention.

[0069] In this embodiment, such as Figures 1 to 11 As shown, the organ box connector assembly according to the present invention includes a first connector 1, a hose 2, an intermediate connecting assembly 3, and a second connector 4. The first connector 1 has an exhaust port 11 for venting gas, a hose connection portion 12, and a pipeline interface 13. The exhaust port 11 is used to expel gas from the organ or gas from the circulation loop used to maintain the activity of the organ (e.g., heart, lung, kidney, etc.). The pipeline interface 13 is used to connect to the organ box outlet pipe (not shown in the figure) through the pipeline assembly to form a circulation loop, thereby maintaining organ activity. Simultaneously, the third connector 52 also transports waste fluid collected in the organ box into the circulation loop. The intermediate connecting assembly 3 is connected to the hose connection portion 12 via the hose 2 and is provided with a first locking member 31. One end of the second connector 4 is inserted into the intermediate connecting assembly 3, and the other end is used to connect to an artery or vein of the organ. The second connector 4 is locked to the intermediate connecting assembly 3 by the first locking member 31. During pre-filling, the intermediate connecting assembly 3 can also be connected to the connector of the organ box outlet pipe located inside the organ box via an auxiliary connecting pipe, and the auxiliary connecting pipe and the intermediate connecting assembly 3 also form a quick-connect structure.

[0070] By adopting the above technical solution, the tubing can be clamped with a pipe wrench after the circuit pre-filling and venting are completed, thus preventing air from being pushed back into the organ under the action of liquid. The tubing can also adaptively adjust its bending angle according to the size of the organ, allowing organs of different sizes to be placed more smoothly in the organ box. After the organ is placed in the organ box, the liquid containing air bubbles can be pushed towards the vent 11 with the pipe wrench, allowing the air bubbles to be expelled from the vent 11, better removing air from the circulation tubing and ensuring the normal operation of the circulation tubing. Simultaneously, by using a tubing, when the organ box connector assembly is installed into the organ box to connect the organ, there is no need to install bends in the tubing to overcome steps, further avoiding the risk of thrombosis at bends, thus improving the safety and reliability of organ maintenance. Finally, the intermediate connecting component and the second connector use a plug-in connection instead of the existing threaded connection, making the connection simple and convenient, avoiding the twisting and bending of the tubing caused by threaded connections, thereby ensuring the stability and reliability of the tubing installation.

[0071] In one implementation, such as Figure 3 As shown, the first connector 1 has a bent portion 14, and the exhaust port 11 is located between the hose connection portion 12 and the pipeline interface 13, and is disposed on one side of the bent portion 14.

[0072] In one embodiment, the hose connector 12 can be configured as a pagoda connector, which facilitates quick insertion and installation of the hose 2 and provides good sealing.

[0073] In one embodiment, the first locking member 31 has a first working position and a second working position. When the first locking member 31 is in the first working position, it restricts the second connector 4 from disengaging from the intermediate connecting assembly 3. When the first locking member 31 is in the second working position, it allows the second connector 4 to disengage from the intermediate connecting assembly 3.

[0074] In one implementation, such as Figure 2 As shown, the intermediate connecting assembly 3 also includes a first elastic element 32 and a first operating element 33. Both the first elastic element 32 and the first operating element 33 are connected to the first locking element 31. Pressing the first operating element 33 can move the first locking element 31 to the second working position (e.g., ...) by overcoming the elastic force of the first elastic element 32. Figure 2As shown), after the external force applied to the first operating member 33 is removed, the compressed first elastic member 32 applies an elastic force to the first locking member 31, causing it to move from the second working position to the first working position and remain in the first working position. At this time, the first locking member 31 locks the second connector 4, preventing it from disengaging from the intermediate connecting assembly 3. It should be understood that after the first locking member 31 is installed in the intermediate connecting assembly 3, its initial position before the second connector 4 is inserted into the intermediate connecting assembly 3 can be the same position as the first working position or a different position.

[0075] In one embodiment, after the first locking member 31, the first elastic member 32 and the first operating member 33 are assembled, the first elastic member 32 is in a compressed state. At this time, a limiting structure (not shown in the figure) can be set to limit the first locking member 31 or the first operating member 33 to prevent the first locking member 31 or the first operating member 33 from being disengaged from the intermediate connecting assembly 3 due to the force of the first elastic member 32.

[0076] In another embodiment, the first elastic member 32 may be omitted, and the first locking member 31 can be moved directly by the first operating member 33, allowing the first locking member 31 to switch between a first working position and a second working position. Furthermore, when the first locking member 31 is in the first working position, an additional locking structure (not shown in the figure) can be provided to lock the first operating member 33, preventing accidental movement of the first operating member 33 that would cause the first locking member 31 to move and unlock the second connector 4.

[0077] It is understood that in another embodiment, the first operating member 33 may not be provided; simply providing the first locking member 31 and the first elastic member 32 can also lock the second connector 4. Specifically, an actuating surface (e.g., a slope or curved surface) can be formed on the second connector 4 and / or the first locking member 31. During the insertion of the second connector 4 into the intermediate connecting assembly 3, the second connector 4 and the first locking member 31 contact each other through the actuating surface. The second connector 4 applies force to the first locking member 31 through the actuating surface, causing the first locking member 31 to compress the first elastic member 32 and move to the second working position. After the second connector 4 is installed in place, the first locking member 31 moves to the first working position under the elastic force of the first elastic member 32, locking the second connector 4. In this embodiment, the second connector 4 can achieve direct plug-in automatic locking without the need for additional operation using the first operating member 33. Compared with the embodiment using the first operating member 33, this embodiment is simpler to operate but relatively labor-intensive and relatively inconvenient to manufacture and install.

[0078] Furthermore, a similar structural principle can be used to achieve direct disassembly of the second connector 4. That is, another actuating surface can be formed on the second connector 4 and / or the first locking member 31. When the second connector 4 is directly pulled down to disassemble it, the second connector 4 applies force to the first locking member 31 through this actuating surface, causing the first locking member 31 to compress the first elastic member 32 and move to the second working position. At this time, the second connector 4 can be disassembled smoothly. In this embodiment, the overall operation is simpler and does not require additional operation of the first operating member 33. However, the locking stability of the second connector 4 is somewhat lacking. If the locking stability of the second connector 4 is to be improved and the second connector 4 is to be prevented from disengaging from the intermediate connecting assembly 3 under accidental force, the force required to disassemble the second connector 4 needs to be increased (for example, by increasing the elastic stiffness of the second elastic member 32), which will make the disassembly of the second connector 4 relatively more difficult.

[0079] In one embodiment, when the second connector 4 is locked, and the second connector 4 is disassembled in a direction opposite to its insertion direction, the force exerted by the second connector 4 on the first locking member 31 is perpendicular to the direction in which the first locking member 31 moves from the first working position to the second working position. This ensures the installation stability of the second connector 4 and prevents it from accidentally detaching from the intermediate connecting assembly 3 under external force, thus avoiding adverse consequences. It should be noted that in this embodiment, the first operating member 33 facilitates active operation to move the first locking member 31 from the first working position to the second working position, thereby enabling the disassembly of the second connector 4 for maintenance or replacement. If the embodiment described above, without the first operating member 33, is used, it will be difficult to disassemble the second connector 4.

[0080] In one implementation, such as Figure 2 and Figure 4 As shown, the first locking member 31 includes a first annular portion 311, a first connecting portion 312, and a second connecting portion 313. The first annular portion 311 is used to lock the second connector 4. The first connecting portion 312 and the second connecting portion 313 are located on opposite radial sides of the first annular portion 311. A first elastic member 32 is sleeved on the first connecting portion 312, and the second connecting portion 313 is connected to the first operating member 33. It should be noted that the first locking member 31 is not limited to using the first annular portion 311 to lock the second connector 4; a curved rod-like structure or other structural forms can also be used to lock the second connector 4.

[0081] In one implementation, such as Figure 4As shown, the first annular portion 311 has a first limiting plane 3111, which is perpendicular to the insertion direction of the second connector 4. Thus, when the second connector 4 is inserted into the intermediate connecting assembly 3, it contacts the first locking member 31 through the first limiting plane 3111. When the second connector 4 is disassembled in the direction opposite to its insertion direction, the force exerted by the second connector 4 on the first locking member 31 is perpendicular to the first limiting plane 3111, preventing the first locking member 31 from moving from the first working position to the second working position. This avoids the second connector 4 accidentally disengaging from the intermediate connecting assembly 3 under external force, thus preventing adverse consequences.

[0082] Furthermore, such as Figure 4 As shown, the first annular portion 311 has a first through hole 3112 through which the second connector 4 passes.

[0083] In one implementation, such as Figure 5 and Figure 6 As shown, the intermediate connecting component 3 also includes a first housing portion 34, which includes a connecting main body portion 341 and an end cap portion 342 that are connected to each other. The connecting main body portion 341 and the end cap portion 342 can be fixedly connected by fasteners, snap-fitting or other means, or they can be integrally formed; the present invention does not limit this.

[0084] In one implementation, such as Figures 6 to 8 As shown, the first housing portion 34 has a mounting guide groove 343, and the first operating member 33 is partially disposed in the mounting guide groove 343. The mounting guide groove 343 can guide and limit the movement of the first operating member 33. Of course, it should be understood that the first operating member 33 may also be completely disposed in the mounting guide groove 343.

[0085] In one implementation, such as Figure 6 and Figure 8 As shown, the first housing portion 34 forms a first chamber 344, which is enclosed by the connecting body portion 341 and the end cap portion 342. A first locking member 31 is partially disposed within the first chamber 344 and is capable of sliding within the first chamber 344 to switch between a first working position and a second working position. Alternatively, the first locking member 31 may be entirely disposed within the first chamber 344.

[0086] In one implementation, such as Figure 2 and Figure 6 As shown, the first housing portion 34 has a connecting hole 345, and one end of the second connector 4 is inserted into the connecting hole 345 along the axial direction of the connecting hole 345. The sliding direction of the first locking member 31 is perpendicular to the axial direction of the connecting hole 345.

[0087] In one implementation, such as Figure 2 and Figure 6 As shown, the first housing portion 34 has a connector 346, and one end of the hose 2 is sleeved onto the connector 346. The connector 346 can be configured as a pagoda connector, which facilitates quick insertion and installation of the hose 2 and provides good sealing. Furthermore, the pagoda connector can be directly formed at the upper end of the first housing portion 34 and extends axially along the first housing portion 34. This simplifies the overall structure of the intermediate connecting assembly 3, makes it easy to manufacture, and facilitates the connection of the hose 2.

[0088] In one implementation, such as Figure 2 , Figure 9 and Figure 10 As shown, a first locking groove 41 is formed on the outer peripheral wall of the second connector 4. Specifically, the first locking member 31 is partially inserted into the first locking groove 41 in the first working position to lock the second connector 4. In one embodiment, the first annular portion 311 is partially inserted into the first locking groove 41 to lock the second connector 4. However, the invention is not limited to this; the first locking member 31 may also be fully inserted into the first locking groove 41.

[0089] In one implementation, such as Figure 2 and Figure 9 As shown, a sealing groove 42 is formed on the outer peripheral wall of the second connector 4. A sealing ring is provided in the sealing groove 42 to improve the sealing performance of the connection between the second connector 4 and the first housing portion 34. Optionally, there are at least two sealing grooves 42, and at least two sealing rings are correspondingly provided therein.

[0090] In one implementation, such as Figure 2 and Figure 9 As shown, the outer peripheral wall of the second connector 4 has an annular groove 43, which is used to connect with the artery or vein of an organ. Multiple annular grooves 43 can be arranged closely together, which increases the contact surface between the artery or vein and the second connector 4, enhancing friction and sealing, and preventing blood leakage.

[0091] The connection process between the second connector 4 and the intermediate connecting assembly 3 is briefly described below.

[0092] First, the main body 341, end cap 342, first locking member 31, first elastic member 32, and first operating member 33 are assembled together. At this time, the first locking member 31 and the first operating member 33 are both in their initial positions. The projections of the first annular portion 311 and the connecting hole 345 along the axial direction of the connecting hole 345 overlap. The first annular portion 311 prevents the second connector 4 from being inserted into the connecting hole 345. The first elastic member 32 is in a compressed state, with one end connected to the inner wall surface of the first housing portion 34 and the other end connected to the first locking member 31.

[0093] When preparing to install the second connector 4, press the first operating member 33 to move the first locking member 31 to the second working position. At this time, the central axes of the first through hole 3112 of the first annular portion 311 and the connecting hole 345 can coincide, and the projections of the first annular portion 311 and the connecting hole 345 along the axial direction of the connecting hole 345 do not overlap, so the second connector 4 can be inserted into the connecting hole 345.

[0094] Furthermore, after the external force applied to the second connector 4 is removed, the first locking member 31 moves from the second working position to the first working position under the action of the first elastic member 32, that is, the first annular portion 311 is partially inserted into the first locking groove 41, thereby locking the second connector 4. At this point, the second connector 4 and the intermediate connecting assembly 3 are connected.

[0095] The process of disassembling the second connector 4 is exactly the reverse of the installation process, and will not be described in detail here.

[0096] This invention also provides an organ transport platform, such as... Figure 11 As shown, the organ transport platform includes an organ box 5. The organ box 5 has a positioning groove (not shown) in its side wall 51. The first connector 1 has a positioning part 15. The first connector 1 is connected to the organ box 5 through the cooperation of the positioning part 15 and the positioning groove. This prevents the first connector 1 from rotating relative to the organ box 5 and facilitates gluing and fixing the first connector 1 to the organ box 5.

[0097] Furthermore, the organ box 5 is also provided with a third connector 52, one end of which is connected to a waste liquid collection tank. The waste liquid collection tank is used to collect waste liquid (blood flowing out of the left ventricular opening and pre-filling fluid, etc.) in the organ box and to transport the waste liquid to the circulation loop.

[0098] In this embodiment, the process of pre-charging the organ box circuit and placing the organ is as follows:

[0099] First, connect the first connector 1, the hose 2, and the intermediate connecting assembly 3 to the organ box. The hose interface 13 of the first connector 1 connects to the organ box's outlet pipe outside the organ box via the hose assembly. Inside the organ box, the intermediate connecting assembly 3 connects to the connector of the organ box's outlet pipe located inside the organ box via an auxiliary connector. The auxiliary connector and the intermediate connecting assembly 3 also form a quick-connect structure, thus creating a closed loop. Pre-filling fluid is introduced into the loop to fill it completely, thereby purging any air from the hose. After pre-filling is complete and the second connector 4 is connected to the organ's blood vessels, clamp the hose 2 to prevent pre-filling fluid from flowing out. By operating the intermediate connecting assembly 3, the auxiliary connector is removed, and the second connector 4 is inserted, completing the quick replacement process. During this process, the hose 2 and the quick-connect structure prevent air from entering. Furthermore, the degree of curvature of the hose 2 can be adjusted according to the organ's size, achieving adaptive placement. Alternatively, liquid containing air bubbles can be pushed towards the vent 11 using a tube clamp, causing the air bubbles to escape from the vent 11. Finally, the blood outlet on the right ventricle connects to the connector inside the organ box via a fluid outlet tube, forming a closed-loop structure and achieving circulatory blood supply to the organ. In this embodiment, the flexible tube includes a first tube wall structure and a second tube wall structure in its circumferential direction. The elastic modulus of the first tube wall structure is greater than that of the second tube wall structure, and the second tube wall structure can be clamped and deformed to seal the fluid channel of the flexible tube. Preferably, the first tube wall structure can be made of braided fabric or polyurethane material, and the second tube wall is made of a flexible film. By setting the first and second tube wall structures with different elastic moduli in the circumferential direction, the portion with the higher elastic modulus ensures the stability of the flexible tube inside the organ box and prevents it from shaking, while the portion with the lower elastic modulus facilitates clamping and sealing the channel.

[0100] In at least one embodiment, the second pipe wall structure is symmetrically arranged and together with the first pipe wall structure forms the hose 2. Preferably, both the second pipe wall structure and the first pipe wall structure are two segments, and the first pipe wall structure and the second pipe wall structure are adjacent and fixedly connected to form a complete hose structure.

[0101] This application embodiment also provides a connector positioning assembly for assistive organ connection, which is used for connection between the assistive organ and the aforementioned second connector 4, as described below. Figures 12 to 18 The specific implementation method is described in detail.

[0102] In one implementation, such as Figure 12 As shown, the connector positioning assembly of the present invention includes a fixed support mechanism 6 and a connecting auxiliary assembly 7 that are interconnected.

[0103] Specifically, in one embodiment, the fixed support mechanism 6 includes a support base 61, a support column 62, and a cross arm 63. The support base 61 is used to place a device containing organs (e.g., an organ box), one end of the support column 62 is connected to the support base 61, one end of the cross arm 63 is slidably connected to the support column 62 so as to be able to move up and down relative to the support column 62 to adjust its position, and the other end is connected to the connecting auxiliary component 7.

[0104] In one implementation, such as Figure 13 As shown, the connecting auxiliary component 7 includes a second housing portion 71, which has a positioning hole 711 for inserting the second connector 4. The positioning hole 711 can be a through hole, with its diameter configured to allow the second connector 4 to be vertically inserted into it from top to bottom and to move downwards out of the positioning hole 711. However, the invention is not limited to this; the second connector 4 can also be inserted into the positioning hole 711 from bottom to top and move downwards out of the positioning hole 711. In this case, the positioning hole 711 can also be configured as a blind hole with its upper end closed, instead of being a through hole. Alternatively, the positioning hole 711 can also be configured such that the diameter of its upper portion is smaller than the maximum diameter of the second connector 4, preventing the second connector 4 from being vertically inserted into the positioning hole 711 from top to bottom.

[0105] In one implementation, such as Figure 14 As shown, the connection auxiliary component 7 includes a second locking member 72, which is disposed in the second housing portion 71 and is movable between a third working position and a fourth working position. In the third working position, the second locking member 72 prevents the second connector 4 inserted into the positioning hole 711 from disengaging from the positioning hole 711, thus positioning the second connector 4 to assist in the connection between the second connector 4 and the organ. In the fourth working position, the second locking member 72 allows the second connector 4 inserted into the positioning hole 711 to move toward the organ and disengage from the positioning hole 711.

[0106] By adopting the above technical solution, the second connector 4 is positioned and fixed using the connector positioning component. Only one operator is needed to connect the organ to the second connector 4, which is simple, convenient, and the connection process is stable.

[0107] In one implementation, such as Figure 14 As shown, the connecting auxiliary component 7 also includes a second elastic element 73, which is connected to the second locking element 72 and is used to move the second locking element 72 from the fourth working position to the third working position and maintain it in the third working position. The second elastic element 73 can be a spring.

[0108] In one implementation, such as Figure 9 and Figure 14As shown, the outer wall of the second connector 4 has a first inclined surface 44, and the second locking member 72 has a second inclined surface 721. In the initial state, the second locking member 72 partially extends into the positioning hole 711, and the second inclined surface 721 is also located within the positioning hole 711. Figure 15 As shown, when the second connector 4 is inserted into the positioning hole 711 from top to bottom, the first inclined surface 44 of the second connector 4 contacts the second inclined surface 721 of the second locking member 72. The second connector 4 applies force to the second locking member 72 through the contact between the first inclined surface 44 and the second inclined surface 721, causing the second locking member 72 to compress the second elastic member 73 and move radially along the positioning hole 711 to the fourth working position. Further, when the second connector 4 continues to move downward to the predetermined position, the second locking groove 45 on the second connector 4 is opposite to the second locking member 72. The second locking member 72 moves to the third working position under the elastic force of the second elastic member 73, that is, the second locking member 72 is partially inserted into the second locking groove 45 to position and lock the second connector 4. The final state is as follows. Figure 16 As shown. Of course, the invention is not limited to this; the second locking member 72 can also be designed to be fully inserted into the second locking slot 45.

[0109] It should be further noted that both the second connector 4 and the second locking member 72 do not necessarily need to form inclined surfaces to achieve force transmission; force transmission can be achieved by either the second connector 4 or the second locking member 72 forming an inclined surface. Furthermore, the inclined surface can be replaced by a curved surface or other forms of actuating surface to achieve force transmission; it does not have to be an inclined surface.

[0110] In another embodiment, the second locking groove 45 may not be formed on the second connector 4. Instead, a step portion is formed, and the second locking member 72 can cooperate with the step portion (for example, the upper surface of the second locking member 72 supports the step surface of the step portion) to support and position the second connector 4 and prevent the second connector 4 from disengaging downward from the positioning hole 711.

[0111] In one implementation, such as Figures 14 to 17 As shown, the connecting auxiliary component 7 also includes a second operating member 74, which is connected to the second locking member 72. Operating the second operating member 74 allows the second locking member 72 to overcome the elastic force of the second elastic member 73 and move from the third working position to the fourth working position. At this time, the second connector 4 can move downwards and disengage from the positioning hole 711.

[0112] In another embodiment, the second operating member 74 may be omitted. When the second locking member 72 is partially inserted into the second locking groove 45 to lock the second connector 4, the second connector 4 and the second locking member 72 can contact each other through an actuating surface (not shown in the figure). At this time, a certain external force is applied to the second connector 4, causing the second connector 4 to move downward. The second connector 4 applies force to the second locking member 72 through the actuating surface, causing the second locking member 72 to move radially to a fourth working position, and the second connector 4 can move downward to disengage from the positioning hole. It is understood that the actuating surface can be formed in at least one of the second locking member 72 and the second connector 4, and its form can be an inclined surface, a curved surface, or other structural forms. It is understood that in this embodiment, since the second operating member 74 is omitted, the operation is simpler, but since the second connector 4 will automatically unlock under a certain external force, its locking stability will be somewhat lacking.

[0113] In one embodiment, when the second locking member 72 is in the third working position locking the second connector 4, the force exerted by the second connector 4 on the second locking member 72 is perpendicular to the direction in which the second locking member 72 moves from the third working position to the fourth working position (i.e., the radial direction of the positioning hole 711). This improves the locking stability of the second connector 4 and prevents it from accidentally disengaging from the positioning hole 711 under external force, thus avoiding adverse consequences. It is understood that in this embodiment, a second operating member 74 is necessary to enable the second locking member 72 to move from the third working position to the fourth working position, thereby unlocking the second connector 4. Without the second operating member 74, it would be difficult to disassemble the second connector 4.

[0114] In one implementation, such as Figure 17 and Figure 18 As shown, the second locking member 72 includes a second annular portion 722, a third connecting portion 723, and a fourth connecting portion 724. The second annular portion 722 is inserted into the second locking groove 45 to lock the second connector 4. The third connecting portion 723 and the fourth connecting portion 724 are located on both radial sides of the second annular portion 722. The second elastic member 73 is sleeved on the third connecting portion 723, and the fourth connecting portion 724 is connected to the second operating member 74. It should be noted that the second locking member 72 is not limited to using the second annular portion 722 to lock the second connector 4; a curved rod-like structure or other structural forms can also be used to lock the second connector 4.

[0115] In one implementation, such as Figure 17 and Figure 18As shown, the second annular portion 722 has a second limiting plane 7221, which is perpendicular to the insertion direction of the second connector 4. Thus, when the second connector 4 is inserted into the positioning hole 711, the second connector 4 contacts the second locking member 72 through the second limiting plane 7221. The force exerted by the second connector 4 on the second locking member 72 is perpendicular to the second limiting plane 7221, preventing the first locking member 31 from moving from the first working position to the second working position. This avoids the second connector 4 accidentally disengaging from the intermediate connecting assembly 3 under external force, thus preventing adverse consequences.

[0116] Furthermore, the second annular portion 722 has a second through hole 7222 through which the second connector 4 passes.

[0117] In one implementation, such as Figure 17 As shown, the second housing portion 71 further includes a limiting portion 712, which abuts against the second locking member 72 to prevent the second locking member 72 from disengaging from the second housing portion 71. The limiting portion 712 is located between the second annular portion 722 and the second operating member 74. It should be understood that the present invention does not limit the specific structural form and location of the limiting portion, as long as it can limit the second locking member 72 and prevent it from disengaging from the second housing portion 71.

[0118] In one implementation, such as Figure 17 As shown, the second housing portion 71 also includes a second chamber 713, and a second locking member 72 is partially disposed in the second chamber 713. The second locking member 72 is slidable in the second chamber 713 to switch between a third working position and a fourth working position. Alternatively, the second locking member 72 may be completely disposed in the second chamber 713.

[0119] Furthermore, the second housing portion 71 includes an upper housing portion 714 and a lower housing portion 715, which are fixedly connected and enclose each other to form a second chamber 713.

[0120] In one implementation, such as Figure 13 As shown, a suture winder 8 is provided on the second housing portion 71 for temporary fixation of the surgical suture, facilitating the connection between the organ and the second connector 4. Multiple suture winders 8 may be provided, and they may be evenly spaced apart circumferentially on the second housing portion 71. Optionally, the suture winder 8 may be located at the lower end of the second housing portion 71.

[0121] The following is a brief description of the method of using the connector positioning component for assisting organ connection of the present invention.

[0122] First, the fixing support mechanism 6 and the connecting auxiliary assembly 7 are assembled. Specifically, the second housing part 71, the second locking member 72, the second elastic member 73, and the second operating member 74 are all assembled. Figure 14 As shown.

[0123] Next, the second connector 4 is inserted from top to bottom into the positioning hole 711 of the second housing portion 71. The second connector 4 causes the second locking member 72 to compress the second elastic member 73 and move radially along the positioning hole 711 to the fourth working position. When the second connector 4 continues to move downward to the predetermined position, the second locking member 72 will move to the third working position under the elastic force of the second elastic member 73, that is, the second locking member 72 is partially inserted into the second locking groove 45, thereby positioning and locking the second connector 4. This process is as follows: Figure 15 and Figure 16 As shown.

[0124] Next, the device containing the organ can be placed on the support 61, and the cross arm 63 can be adjusted to a suitable height position to connect the organ to the second connector 4.

[0125] Finally, after the connection is completed, operate the second operating member 74 to move the second locking member 72 to the fourth working position, and the second connector 4 can then move downwards to disengage from the positioning hole 711. It is understood that the second connector 4 can be further connected to the intermediate connecting assembly 3 to form an organ box connector assembly.

[0126] It should be understood that the above embodiments are all exemplary and are not intended to include all possible embodiments as contained in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of the invention. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of the invention that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of the invention and do not limit the scope of protection of the invention.
