Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a magnet delivery device. Background Technology

[0002] In recent years, with the continuous development of surgical techniques, surgical anastomosis methods have also evolved. Magnetic compression anastomosis utilizes the mutual attraction and compression of tissues by magnets, along with the assistance of a magnetic field, to form an anastomosis between hollow organs. It has advantages such as compact structure, ease of operation, low anastomotic tension, accelerated anastomosis due to the combined force and magnetic action, good serosal alignment, and fewer anastomotic complications. During the anastomosis, the magnet needs to be delivered into the body.

[0003] Existing delivery devices use clamps to hold and fix the magnet, then transport the magnet via the clamps. In this method of magnet transport and fixation, the connection stability between the clamps and the magnet is poor, which can affect the stability of the surgical procedure. Utility Model Content

The handle assembly and the clamp assembly are connected by a rod drive. The magnetic block is provided with a slot for partially accommodating the clamp assembly. The handle assembly controls the clamp assembly to switch between opening and closing. When the clamp assembly is open, it is engaged with the inner wall of the slot. When the clamp assembly is closed, it is disengaged from the slot.

[0030] Please refer to Figure 1 and Figure 2 This embodiment provides a magnet conveying device 100, including a magnet 110 and a conveying clamp 120. The conveying clamp 120 includes a sleeve 121 and a clamp assembly 122 disposed at the distal end of the sleeve 121. A handle assembly 123 is disposed at the proximal end of the sleeve 121. The handle assembly 123 and the clamp assembly 122 are connected by a rod 124. The magnet 110 is provided with a slot 111 for partially accommodating the clamp assembly 122. The handle assembly 123 controls the clamp assembly 122 to switch between opening and closing. When the clamp assembly 122 is open, it is engaged with the inner wall of the slot 111. When the clamp assembly 122 is closed, it is disengaged from the slot 111.

[0031] Specifically, a slot 111 is provided on the magnetic block 110, which is used to partially accommodate the clamp assembly 122. By operating the handle assembly 123, the clamp assembly 122 can be flexibly switched between open and closed states. When the clamp assembly 122 is open, it is tightly engaged with the inner wall of the slot 111, thereby firmly fixing the magnetic block 110; when the clamp assembly 122 is closed, it disengages from the slot 111, facilitating the release of the magnetic block 110. When the clamp assembly 122 is open, it is engaged with the inner wall of the slot 111. When the handle assembly 123 is rotated, the clamp assembly 122 rotates with the handle assembly 123, thereby driving the magnetic block 110 to rotate synchronously, so as to adjust the placement angle of the magnetic block 110.

[0032] When using this magnet delivery device 100, first insert the clamp assembly 122 into the slot 111 of the magnet 110. Then, operate the handle assembly 123 to move it in a specific direction. Through the transmission action of the insertion rod 124, the clamp assembly 122 opens. After the clamp assembly 122 opens, its jaws make tight contact with the inner wall of the slot 111 and form a clamp, thereby firmly fixing the magnet 110 onto the delivery clamp 120. At this time, the doctor can hold the handle assembly 123 and use the delivery clamp 120 to accurately deliver the magnet 110 to the predetermined surgical site inside the body. When the magnet 110 reaches the predetermined position, operate the handle assembly 123 again to move it in the opposite direction. The insertion rod 124 drives the clamp assembly 122 to close, the clamp assembly 122 disengages from the slot 111, and the magnet 110 is released from the delivery clamp 120, completing the magnet delivery operation.

[0033] The magnet conveying device 100 provided in this application includes a magnetic block 110 and a conveying clamp 120. The conveying clamp 120 includes a sleeve 121 and a clamp assembly 122 disposed at the distal end of the sleeve 121. A handle assembly 123 is disposed at the proximal end of the sleeve 121. The handle assembly 123 and the clamp assembly 122 are connected by a rod 124. The magnetic block 110 is provided with a slot 111 for partially accommodating the clamp assembly 122. The handle assembly 123 controls the clamp assembly 122 to switch between opening and closing. When the clamp assembly 122 is open, it is engaged with the inner wall of the slot 111. When the clamp assembly 122 is closed, it is disengaged from the slot 111. By providing a slot 111 on the magnetic block 110 and using the clamp assembly 122 to engage with the slot 111 to fix the magnetic block 110, the connection stability between the clamp assembly 122 and the magnetic block 110 is significantly improved compared to the traditional clamping method. When the clamp assembly 122 opens, it is tightly engaged with the inner wall of the slot 111, which can effectively prevent the magnetic block 110 from loosening or falling off during the transport process, ensuring the stability and safety of the surgical operation and reducing the surgical risk.

[0034] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the chuck assembly 122 includes a first chuck 1221 and a second chuck 1222 rotatably connected to the distal end of the sleeve 121 via a first rotating shaft 1223. The first chuck 1221 is rotatably connected to the distal end of the insertion rod 124 via a first connecting rod 1224, and the second chuck 1222 is rotatably connected to the distal end of the insertion rod 124 via a second connecting rod 1225.

[0035] Specifically, the clamp assembly 122 of this application, through a linkage transmission structure, allows the insertion rod 124 to move under the action of the handle assembly 123, thereby driving the first clamp 1221 and the second clamp 1222 to rotate around the first rotating shaft 1223 via the first linkage 1224 and the second linkage 1225 respectively, thus switching the clamp assembly 122 between open and closed states. In actual operation, when the insertion rod 124 moves to the distal end, the linkage of the first linkage 1224 and the second linkage 1225 causes the first clamp 1221 and the second clamp 1222 to rotate outward and open, engaging in the slot 111 of the magnetic block 110; conversely, when the insertion rod 124 moves in the opposite direction, the first clamp 1221 and the second clamp 1222 rotate inward and close, disengaging from the slot 111. The first clamp 1221 and the second clamp 1222 are symmetrically distributed and connected to the insertion rod 124 via a connecting rod. When clamping and releasing the magnetic block 110, the two clamps are subjected to uniform force, which can ensure that the magnetic block 110 remains stable during the transport process and is not prone to shaking or deviation, further improving the stability of the magnetic transport and providing reliable protection for surgical operations.

[0036] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the first connecting rod 1224, the second connecting rod 1225 and the insert rod 124 are rotatably connected by the second rotating shaft 1226.

[0037] Specifically, during the movement of the insertion rod 124, the first connecting rod 1224 and the second connecting rod 1225 can rotate more smoothly around the second rotating shaft 1226, thereby precisely controlling the opening and closing actions of the first chuck 1221 and the second chuck 1222. The setting of the second rotating shaft 1226 ensures the consistency of linkage between the three components, ensuring that the chuck assembly 122 can respond accurately when the handle assembly 123 is operated, realizing the stable function of gripping and releasing the magnetic block 110.

[0038] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the first rotating shaft 1223 and the second rotating shaft 1226 are located in the extension direction of the insertion rod 124.

[0039] Specifically, this layout makes the transmission path of the clamp assembly 122 more direct and smooth, and the moving force of the insertion rod 124 can be transmitted to the first clamp 1221 and the second clamp 1222 to the maximum extent, reducing energy loss and force dispersion during the transmission process. When the doctor operates the handle assembly 123 to move the insertion rod 124, the linear motion of the insertion rod 124 can be efficiently converted into the rotation of the first clamp 1221 and the second clamp 1222 around the first rotating shaft 1223. Furthermore, since the second rotating shaft 1226 extends in the same direction as the insertion rod 124, the stability and accuracy of the entire transmission process are further guaranteed, ensuring that the clamp assembly 122 can quickly and accurately achieve opening and closing actions.

[0040] In one possible embodiment of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the handle assembly 123 includes a gripper 1231 fixedly connected to the proximal end of the sleeve 121 and an operating member 1232 slidably connected to the sleeve 121. The operating member 1232 is connected to the insertion rod 124.

[0041] Specifically, the gripper 1231 provides the surgeon with a stable gripping point, facilitating the operation of the entire delivery device during surgery. The operating component 1232, connected to the insertion rod 124, allows the surgeon to move the insertion rod 124 within the cannula 121 by sliding the operating component 1232, thereby controlling the opening and closing of the clamp assembly 122. For example, the surgeon can grip the gripper 1231 and push or pull the operating component 1232 with their fingers to grasp and release the magnetic block 110. This simple and intuitive operation meets the actual needs of surgical procedures.

[0042] In one possible embodiment of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an elastic reset member 1233 is provided between the operating member 1232 and the gripping member 1231, and the two ends of the elastic reset member 1233 are respectively connected to the operating member 1232 and the gripping member 1231.

[0043] Specifically, the elastic reset member 1233 is a compression spring. When the magnet is being transported, the elastic potential energy stored in the elastic reset member 1233 is used to push the operating member 1232 toward the distal end when the operating member 1232 is released. This causes the insertion rod 124 to move toward the distal end. The linkage between the first connecting rod 1224 and the second connecting rod 1225 causes the first clamp 1221 and the second clamp 1222 to rotate outward and open, locking into the slot 111 of the magnetic block 110. The elastic reset member 1233 can keep the first connecting rod 1224 and the second connecting rod 1225 in an open state, thereby improving the convenience of magnet transport.

[0044] In one possible embodiment of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the gripper 1231 is provided with a receiving cavity, and the elastic reset member 1233 is disposed in the receiving cavity.

[0045] The accommodating cavity provides comprehensive physical protection for the compression spring, isolating it from external factors that may damage it. This effectively extends the spring's lifespan, ensures the long-term stable operation of the device's automatic reset function, reduces device malfunctions and maintenance costs due to spring damage, and improves the device's reliability and durability. Concealing the compression spring within the accommodating cavity makes the surface of the gripper 1231 smoother and more ergonomic. When surgeons hold the gripper 1231 for extended periods during surgical procedures, they are not affected by friction or pressure from the spring, significantly improving grip comfort and operational smoothness. This helps surgeons focus more intently and efficiently on surgical procedures, improving the quality and efficiency of the procedure.

[0046] In one possible embodiment of this application, such as Figure 4 , Figure 5 and Figure 6 As shown, the gripper 1231 is provided with a locking ridge 1231a, and the operating member 1232 is provided with a locking member 1232a. When the locking member 1232a is locked with the locking ridge 1231a, the clamping assembly 122 is closed. When the locking member 1232a is disengaged from the locking ridge 1231a, the clamping assembly 122 is opened.

[0047] Furthermore, the locking prism 1231a is provided with a groove 1231b, through which the locking member 1232a can pass. The operating member 1232 is rotatably connected to the insertion rod 124. Rotating the operating member 1232 can lock or unlock the locking member 1232a and the locking prism 1231a.

[0048] During the procedure, the doctor rotates the operating component 1232 to align the locking member 1232a with the through slot 1231b. Then, the doctor pushes the operating component 1232 towards the distal end, causing the insertion rod 124 to move towards the distal end. The linkage between the first connecting rod 1224 and the second connecting rod 1225 causes the first clamp 1221 and the second clamp 1222 to rotate outward and open, locking into the slot 111 of the magnetic block 110. After the delivery is completed, the doctor pushes the operating component 1232 towards the proximal end until the locking member 1232a passes through the through slot 1231b. Then, the doctor rotates the operating component 1232 to lock the locking member 1232a with the locking edge 1231a, and the clamp assembly 122 is in a closed state.

[0049] In one possible embodiment of this application, such as Figure 1 and Figure 5 As shown, the gripper 1231 has a gripping hole 1231c at its proximal end, through which a finger can be inserted.

[0050] Specifically, the design of the gripper 1231c allows the surgeon's fingers to be directly and securely connected to the gripper 1231, greatly enhancing the grip strength between the hand and the device and effectively preventing the device from slipping or falling off during surgical procedures. During prolonged or complex surgical operations, the surgeon can maintain a stable grip, improving the accuracy and safety of the operation and ensuring its smooth progress.

[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
