Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a triangular liver suspension device. Background Technology
[0002] Laparoscopic surgery, as a minimally invasive surgical method, is widely used in surgery due to its characteristics of minimal trauma and rapid recovery. In liver-related surgeries, it is often necessary to suspend the liver to fully expose the surgical field.
[0003] Existing liver suspension methods have several shortcomings: Surgical complexity: In traditional surgery, liver suspension typically relies on the surgeon's experience and skill, using surgical instruments to directly lift the liver. This not only increases the difficulty of the surgery but also prolongs the operation time. Surgical risks: Direct contact of surgical instruments with the liver may cause liver tissue damage or bleeding, increasing the risk of intraoperative complications. Insufficient visual exposure: Current technologies struggle to provide adequate visual exposure for liver surgeries in complex locations, limiting the precision and safety of the procedure. Equipment limitations: Existing liver suspension devices are often complex in design, difficult to operate, and have limited use in laparoscopic surgery, failing to meet the diverse surgical needs. Utility Model Content
[0004] The purpose of this invention is to provide a triangular liver suspension device. This device has a novel design and reasonable structure, which can improve surgical efficiency and visual exposure quality while ensuring surgical safety. It is suitable for various laparoscopic liver surgeries.
[0005] This utility model is achieved through the following technical solution: a triangular liver suspension device, the main body of which is a triangular TPU film sheet 1;
[0006] A first traction rope 21 is fixed at the top corner of the TPU film sheet 1;
[0007] A second traction rope 22 is provided at the top corner opposite the edge of the TPU film sheet 1;
[0008] Among them, a strip-shaped rolled edge 12 is provided between the two bottom corners and at the opposite side of the top corner, and a lower right rolled edge 11 is provided at the bottom corner on the right side. The second traction rope 22 is fixed at the bottom corner on the left side. The second traction rope 22 passes through the strip-shaped rolled edge 12 and the lower right rolled edge 11 in sequence, and extends out to the lower right rolled edge 11.
[0009] Compared with previous technologies, the beneficial effects of this utility model are as follows:
[0010] 1. This utility model conforms to the minimally invasive principle of laparoscopic surgery. It is simple in design, easy to operate, and easy for surgeons to master and use quickly. It can reduce direct contact with the liver during surgery, reduce the risk of damage and bleeding, and can also adapt to different types and locations of liver surgery, providing stable suspension support and reducing trauma to the patient's body.
[0011] 2. Using TPU films, which have advantages such as biocompatibility, non-toxicity, durability and antibacterial properties, to support the liver can reduce the impact on the liver during surgery. Moreover, the interaction between TPU films and human tissues and body fluids is almost negligible, and it is not likely to trigger an immune response or allergic reaction in the human body.
[0012] 3. The TPU film and TPU edge are joined together using a hot-stamping process, which can achieve a seamless connection while withstanding good tensile and shear forces, and is not easy to crack or separate. Attached Figure Description

[0015] Labeling explanation: 1 TPU film, 11 lower right curled edge, 12 strip curled edge, 13 lower left curled edge, 14 top curled edge, 21 first traction rope, 22 second traction rope. Detailed Implementation
[0016] The present invention will now be described in detail with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description:
[0017] like Figure 1 and Figure 2 As shown, the triangular liver suspension device has a triangular TPU film sheet 1 as its main body;
[0018] A first traction rope 21 is fixed at the top corner of the TPU film sheet 1;
[0019] A second traction rope 22 is provided at the top corner opposite the edge of the TPU film sheet 1;
[0020] Among them, a strip-shaped rolled edge 12 is provided between the two bottom corners and at the opposite side of the top corner, and a lower right rolled edge 11 is provided at the bottom corner on the right side. The second traction rope 22 is fixed at the bottom corner on the left side. The second traction rope 22 passes through the strip-shaped rolled edge 12 and the lower right rolled edge 11 in sequence, and extends out to the lower right rolled edge 11.
[0021] This invention conforms to the minimally invasive principle of laparoscopic surgery. It is simple in design, easy to operate, and easy for surgeons to quickly master and use. It can reduce direct contact with the liver during surgery, reduce the risk of damage and bleeding, and can also adapt to different types and locations of liver surgery, providing stable suspension support and reducing trauma to the patient's body.
[0022] Using TPU films, which have advantages such as biocompatibility, non-toxicity, durability and antibacterial properties, to support the liver can reduce the impact on the liver during surgery. Moreover, the interaction between TPU films and human tissues and body fluids is almost negligible, and it is unlikely to trigger an immune response or allergic reaction in the human body.
[0023] When the second traction rope 22 passes through the lower right rolled edge 11, it wraps around the lower right rolled edge 11 once and extends out of the lower right rolled edge 11.
[0024] This design allows for control over the degree of adjustment of the second traction rope 21.
[0025] The top corner is provided with a top rolled edge 14, and the first traction rope 21 is tied to the top rolled edge 14; the bottom corner on the left side is provided with a lower left rolled edge 13, and the second traction rope 21 is tied to the lower left rolled edge 13.
[0026] The top rolled edge 14, the lower left rolled edge 13, the lower right rolled edge 11, and the strip rolled edge 12 are made of TPU material, and the top rolled edge 14, the lower left rolled edge 13, the lower right rolled edge 11, and the strip rolled edge 12 are heat-bonded to the TPU film through a heat-bonding process.
[0027] The top rolled edge 14, lower left rolled edge 13, lower right rolled edge 11, and strip rolled edge 12 are heat-bonded onto the TPU film using a heat-bonding process. The TPU film and each rolled edge are connected together using a heat-bonding process, which can achieve a seamless connection while being able to withstand good tensile and shear forces, and is not easy to crack or separate.
[0028] In summary, the method of using this utility model is as follows: using a laparoscopic forceps to grasp and pull the traction suture, causing the TPU edge 11 to move, thereby changing the position of the TPU film 1, so that the TPU film 1 can support and protect the liver, facilitating surgical operations. Specifically, the TPU film 1 is placed below the liver that needs to be suspended (such as the left lateral lobe of the liver), and the suture loops at the lower right rolled edge 11 and strip rolled edge 12 are fixed to the ligaments below the liver using ligature clips or other fixing materials. The end of the second traction rope 21 is grasped with a laparoscopic forceps and pulled out of the body, and knotted and fixed outside the body, thereby suspending the liver. The height of the liver suspension can be adjusted by adjusting the length of the second traction rope 21.
[0029] Although this utility model has been illustrated and described using specific embodiments and alternative methods, it should be understood that various changes and modifications are permitted as long as they do not depart from the spirit and scope of this utility model. Therefore, it should be understood that this utility model is not limited in any sense except by the appended claims and their equivalents.
