Description

Technical Field

[0001] This utility model relates to the field of laparoscopic surgical equipment technology, and more specifically, to a magnetic surgical traction device for laparoscopic surgery. Background Technology

[0002] Modern surgery aims for minimally invasive procedures and rapid recovery, thus requiring surgical incisions to be as small and few as possible while ensuring the necessary surgical procedures are performed. Laparoscopic techniques have flourished in recent years. However, during surgery, assistants or abdominal wall traction are often needed to pull organs out of the field of vision. These additional incisions can cause damage to the body, contradicting the goals of minimally invasive surgery. Furthermore, previous abdominal traction devices have problems such as the potential for damage to abdominal organs and the need for additional openings.

[0003] A Chinese utility model patent, publication number CN218186852U, discloses a magnetically anchored organ tissue elastic traction device. It includes an outer magnetic device and inner magnetic traction components positioned opposite each other on the inner and outer sides of the abdominal wall. At least two inner magnetic traction components are provided, each including an inner magnetic element and a non-magnetic traction unit for traction of organ tissue. The non-magnetic traction unit is connected to the inner magnetic element. The outer magnetic device fixes the inner magnetic element to the inner side of the abdominal wall through a magnetic field. The non-magnetic clamping part is a non-magnetic titanium alloy clamp. This device can fix multiple inner magnetic traction components at once; prevents tissue edge drooping from affecting the surgical field; solves the problem of non-magnetic traction units being too far from the tissue to clamp it; and automatically pulls up the tissue after separation using elastic force. The outer magnetic block allows each inner magnetic traction component to be independent, improving the flexibility of use; it eliminates the need for additional operating holes on the patient's body, reducing surgical trauma; and it is simpler to install and use.

[0004] However, in the above-mentioned technical solution, the patient's organs are clamped by non-magnetic titanium alloy clamps, which may cause damage to the surface of the organs during the clamping process, affecting the normal function of the clamped organs. Utility Model Content

[0005] To address the technical problems of existing technologies that require additional openings in the abdominal wall for organ traction, which can easily damage the organs, this invention provides a laparoscopic magnetic surgical traction device. This device can pull in different directions and has a wide range of motion. It can be used in various laparoscopic surgeries, has wide applications, and significant clinical value. Furthermore, it eliminates the need for a dedicated traction hole in the abdominal wall, reducing trauma to the patient during surgery.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a magnetic surgical traction device for laparoscopy, including a suction cup device, a traction rod and a permanent magnet. The suction cup device is adsorbed onto the surface of the organ, the traction rod is detachably connected to the suction cup device, a first magnetic suction element is provided on the suction cup device, and the permanent magnet is attached to the outer side of the abdominal wall and is attracted to the first magnetic suction element.

[0007] In this technical solution, during laparoscopic surgery, an incision is first made in the patient's abdominal wall. Medical personnel hold a traction rod and use it to insert the suction cup device into the mounting device through the incision. This eliminates the need for manual insertion of the suction cup device, reducing the size of the abdominal incision and lowering the risk of infection. The incision also heals more easily, facilitating postoperative recovery. After inserting the suction cup device into the abdominal cavity, it is attached to the surface of the organ to be moved. A pressure difference is created between the inside and outside of the suction cup device to firmly adhere it to the organ's surface. This fixation method ensures stable fixation without requiring drilling or clamping into the organ's surface, thus preventing damage. After securing the suction cup device, the traction rod is removed, leaving only the suction cup device inside the patient's abdominal cavity. The suction cup device is equipped with a first magnetic chuck. When medical staff need to move an organ, they simply hold a permanent magnet and move it along the outside of the patient's abdominal wall. The permanent magnet will then magnetically attract the first magnetic chuck on the suction cup device, causing the first magnetic chuck to move along with the permanent magnet. Ultimately, this movement of the suction device pulls the patient's organ, thus changing its position and creating space for the medical staff to perform the surgical procedure. During this process, due to the characteristics of magnetism, the permanent magnet does not need to establish a physical connection with the first magnetic chuck; it can move the first magnetic chuck even through the patient's abdominal wall. No additional holes need to be drilled in the abdominal wall, and the movement of the first magnetic chuck by the permanent magnet is not affected by any openings in the abdominal wall, allowing for greater freedom in organ movement. After the surgical procedure is completed, simply moving the permanent magnet away from the patient's abdominal wall releases the fixation on the first magnetic chuck. When it is necessary to remove the suction cup device, medical staff only need to use medical forceps to pull on the edge of the suction cup device to break the air pressure difference between the inside and outside of the device, thereby peeling the suction cup device off the organ surface and completing the disassembly. The entire disassembly process is simple and convenient, and will not damage the patient's organ surface.

[0008] Preferably, the lower end of the traction rod is provided with a second magnetic attractor, which is magnetically connected to the first magnetic attractor.

[0009] Preferably, the second magnetic component is an electromagnet, and the second magnetic component is connected to an external power source via a wire, which is located inside the traction rod.

[0010] Preferably, the suction cup device includes a suction cup body, which is an inverted bowl-shaped structure. A connecting tube is provided at the top of the suction cup body, and a one-way valve is also provided at the top of the suction cup body. The one-way valve connects the connecting tube to the bottom of the suction cup body. The first magnetic suction element is an annular structure provided at the top of the connecting tube and arranged along the outer contour of the connecting tube. The traction rod is a hollow tubular structure with open ends. The second magnetic suction element is an annular structure arranged along the outer contour of the traction rod. The top of the traction rod is connected to an external suction machine through an air pipe.

[0011] Preferably, the outer contour of the suction cup body is circular, and the outer contour diameter of the suction cup body is between 0.5cm and 1.5cm.

[0012] Preferably, the top of the first magnetic attractor is an upwardly convex arc-shaped structure.

[0013] Preferably, the bottom surface of the second magnetic element is provided with an arc-shaped groove, the shape of which matches the upward-convex arc structure of the first magnetic element.

[0014] Preferably, the surface of the arc-shaped groove of the second magnetic component is further provided with a rubber sealing layer, which abuts against the first magnetic component.

[0015] Preferably, a clamping portion is provided at the edge of the upper surface of the suction cup body.

[0016] Preferably, the end of the permanent magnet that is in contact with the abdominal wall has an arc-shaped surface structure.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, a suction cup device is provided to adsorb and fix the organs, which is simple and quick and does not damage the surface of the organs. The suction cup device is provided with a first magnetic element that can be attracted to a permanent magnet. The permanent magnet can drive the suction cup device to pull the organs to move through the patient's abdominal wall, eliminating the need for additional traction holes in the abdominal wall, reducing the complexity of the surgical operation and minimizing trauma to the patient during the operation.

[0024] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0025] Example 1

[0026] like Figure 1As shown, a magnetic surgical traction device for laparoscopy includes a suction cup device 1, a traction rod 2, and a permanent magnet 3. The suction cup device 1 is attached to the surface of the organ. The traction rod 2 is detachably connected to the suction cup device 1. A first magnetic suction element 11 is provided on the suction cup device 1. The permanent magnet 3 is attached to the outer side of the abdominal wall and is attracted to the first magnetic suction element 11. During laparoscopic surgery, an incision is first made in the patient's abdominal wall. Medical personnel hold the traction rod 2 and insert the suction cup device 1 into the device through the incision in the patient's abdominal wall. This eliminates the need for manual insertion of the suction cup device 1 into the patient's body, reducing the need for an excessively large incision in the abdominal wall and lowering the risk of infection. The incision also heals more easily, facilitating postoperative healing. After inserting the suction cup device 1 into the patient's abdominal cavity, the medical personnel attach it to the surface of the organ to be moved. A pressure difference is created between the inside and outside of the suction cup device 1, thus firmly attaching it to the surface of the organ. This fixation method ensures stable fixation without requiring drilling or clamping on the organ surface, thus preventing damage to the organ. After fixing the suction cup device 1, medical personnel remove the traction rod 2 from the suction cup device 1, leaving only the suction cup device 1 inside the patient's abdominal cavity. The suction cup device 1 is equipped with a first magnetic suction element 11 that can be attracted to the permanent magnet 3. When medical personnel need to move the organ, they only need to hold the permanent magnet 3 and move it on the outside of the patient's abdominal wall. The permanent magnet 3 will attract the first magnetic suction element 11 on the suction cup device 1 through magnetic force, thereby moving the first magnetic suction element 11 along with the permanent magnet 3. Ultimately, this movement of the suction device pulls the patient's organ, thereby changing the organ's position and making room for the medical personnel's surgical operations. During this process, due to the properties of magnetism, the permanent magnet 3 does not need to establish a physical connection with the first magnetic suction component 11. It can move the first magnetic suction component 11 even through the patient's abdominal wall, eliminating the need for external openings in the abdominal wall. Furthermore, the movement of the first magnetic suction component 11 by the permanent magnet 3 is not affected by any openings in the abdominal wall, allowing for greater freedom in the movement of the organs. After the surgical procedure is completed, simply moving the permanent magnet 3 away from the patient's abdominal wall releases the fixation on the first magnetic suction component 11. When it is necessary to remove the suction cup device 1, medical personnel only need to use medical forceps to pull on the edge of the suction cup device 1 to break the air pressure difference formed inside and outside the suction cup device 1, thereby peeling the suction cup device 1 off the surface of the organ and completing the disassembly of the suction cup device 1. The entire disassembly process is simple and convenient, and will not damage the surface of the patient's organs.

[0027] like Figure 2As shown, a second magnetic element 21 is provided at the lower end of the traction rod 2, and the second magnetic element 21 is magnetically connected to the first magnetic element 11. The traction rod 2 is maintained and connected to the suction cup device 1 by magnetic force without the need for a physical connection structure, making it easy to disassemble the traction rod 2 and the suction cup device 1 without the need for a complex mechanical structure. Once the suction cup device 1 is attached to the organ, medical personnel only need to overcome the attraction between the first magnetic element 11 and the second magnetic element 21 to separate the traction rod 2 from the suction cup device 1.

[0028] like Figure 2 As shown, the second magnetic chuck 21 is an electromagnet, connected to an external power source via a wire housed inside the traction rod 2. By using an electromagnet, the magnetic force of the second magnetic chuck 21 can be adjusted by changing the current flowing through it. When it is necessary to separate the traction rod 2 from the suction cup device 1, simply disconnecting the power supply to the second magnetic chuck 21 will cause its magnetic force to disappear, allowing medical personnel to directly separate the traction rod 2 from the suction cup device 1. The wire providing power to the second magnetic chuck 21 is housed inside the traction rod 2, serving both electrical protection and ensuring that there is no risk of infection from contact between the wire and the patient during surgery.

[0029] Example 2

[0030] This embodiment is similar to Embodiment 1 above, except that, as Figure 2 As shown, the suction cup device 1 includes a suction cup body 12, which is an inverted bowl-shaped structure. A connecting pipe 13 is provided at the top of the suction cup body 12, and a one-way valve 14 is also provided at the top of the suction cup body 12. The one-way valve 14 connects the connecting pipe 13 and the suction cup body 12. The first magnetic suction member 11 is a ring-shaped structure provided at the top of the connecting pipe 13 and arranged along the outer contour of the connecting pipe 13. The traction rod 2 is a hollow tubular structure with open ends. The second magnetic suction member 21 is a ring-shaped structure arranged along the outer contour of the traction rod 2. The top of the traction rod 2 is connected to an external suction machine through an air pipe. Both the first magnetic suction member 11 and the second magnetic suction member 21 are ring-shaped structures, and the inner rings of the first magnetic suction member 11 and the second magnetic suction member 21 provide a channel for gas to pass through. The suction cup body 12 has an inverted bowl-shaped structure, which creates a closed space on the surface of the organ after it is attached to it. The suction machine provides suction, which draws the air out of the closed space through the one-way valve 14, the connecting pipe 13, and the traction rod 2, creating a negative pressure in the closed space relative to the outside, thereby fixing the suction cup device 1 to the surface of the organ. The one-way valve 14 is used to restrict the direction of gas flow and prevent backflow of gas from disrupting the negative pressure in the closed space.

[0031] like Figure 3As shown, the outer contour of the suction cup body 12 is circular, with a diameter between 0.5cm and 1.5cm. Setting the outer contour of the suction cup body 12 to be circular ensures a smooth surface without sharp corners, preventing it from piercing the organ surface and thus avoiding organ damage. Setting the outer contour diameter between 0.5cm and 1.5cm ensures sufficient suction force while maintaining a small size, allowing it to enter the patient's abdominal wall and move freely, minimizing impact on the organs.

[0032] Example 3

[0033] This embodiment is similar to Embodiment 1 above, except that, as Figure 2 As shown, the top of the first magnetic suction element 11 is an upwardly convex arc-shaped structure. When the permanent magnet 3 attracts the first magnetic suction element 11, the top of the first magnetic suction element 11 abuts against the inner wall surface of the patient's abdominal wall. Setting the top of the first magnetic suction element 11 as an upwardly convex arc-shaped structure makes its surface smooth and without sharp corners, so that the abdominal wall will not be scratched when the first magnetic suction element 11 abuts against the abdominal wall or moves on the abdominal wall.

[0034] like Figure 2 As shown, the bottom surface of the second magnetic chuck 21 is provided with an arc-shaped groove, the shape of which matches the upward-convex arc structure of the first magnetic chuck 11. The insertion of the first magnetic chuck 11 into the arc-shaped groove increases the contact area between the first magnetic chuck 11 and the second magnetic chuck 21, making the connection between the first magnetic chuck 11 and the second magnetic chuck 21 more stable, and at the same time enhancing the airtightness after the first magnetic chuck 11 and the second magnetic chuck 21 are attracted together.

[0035] like Figure 2 As shown, the surface of the arc-shaped groove of the second magnetic member 21 is also provided with a rubber sealing layer, which abuts against the first magnetic member 11. The rubber sealing layer is used to enhance the sealing between the first magnetic member 11 and the second magnetic member 21, and to prevent gas leakage from affecting the suction cup device 1 to form a negative pressure.

[0036] like Figure 1 As shown, a clamping part 15 is provided at the edge of the upper surface of the suction cup body 12. When it is necessary to remove the suction cup body 12 from an organ, medical personnel can use medical forceps to clamp the clamping part 15 to lift the suction cup body 12 at the edge.

[0037] like Figure 1 As shown, the end of the permanent magnet 3 that is in contact with the abdominal wall has an arc-shaped surface structure. The surface of the arc-shaped structure is relatively smooth, so that the permanent magnet 3 will not scratch the patient's abdominal wall when it is in contact with the patient's abdominal wall.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
