Description

Technical Field

[0001] This utility model relates to a pneumatic push bar used in laparoscopic surgery, belonging to the field of medical device technology. Background Technology

[0002] Medical forceps are often used in surgical procedures. However, the tips of current medical forceps are relatively sharp and can easily damage organs in the abdominal cavity. For example, in laparoscopic surgery, it is often necessary to move the liver to ensure the smooth progress of the operation. However, sharp medical forceps can easily damage the liver.

[0003] Laparoscopic surgery is gaining increasing attention and is being widely used. Compared with traditional open surgery, laparoscopic surgery has several advantages, including less trauma, faster recovery, smaller and more aesthetically pleasing scars, clearer surgical field, more precise operation, and reduced postoperative adhesions and complications.

[0004] However, laparoscopic surgery does present some challenges, particularly in tissue exposure. Due to the smaller incisions in laparoscopic surgery, surgical instruments and the laparoscope itself must enter the abdominal cavity through these small openings, which somewhat limits the surgical field. Therefore, various methods are employed to fully expose the surgical field during the procedure. The most common method is tension traction exposure, but when using this method, medical forceps pulling on tissue can cause slippage or tissue tearing. Therefore, there is an urgent need to design auxiliary instruments with specific functions to help the operator fully expose the surgical field according to different needs.

[0005] Meanwhile, a certain tension is required when separating tissues during surgery. In laparoscopic surgery, this tension can only be provided by pushing and pulling tissues using medical clamps and other equipment. Providing tissue traction and tension is a more challenging task compared to traditional open surgery. Because the incisions in laparoscopic surgery are smaller and the operating space for surgical instruments is limited, it is difficult to directly pull tissues as in open surgery.

[0006] To provide the necessary tension, surgical instruments such as non-invasive retractors, suction devices, and clamps are commonly used to push and pull the tissue to achieve the required tension. While providing tension, this method may subject the tissue to uneven forces, increasing the risk of tissue damage.

[0007] During traction, a triangular traction pattern is generally used, which forms a stable plane through traction at three points. These three points are typically the surgeon's surgical instruments, the assistant's traction instruments, and the fixation points of the tissue itself. While this pattern provides stable traction, it places high demands on the fixation points of the tissue, which can easily lead to traction instability.

[0008] If suspension and rollover techniques are used to fix tissues for an extended period of time, the tissues may be compressed or not exposed adequately due to excessively tight or loose suspension.

[0009] Laparoscopic surgery of the upper abdomen often requires maneuvering the liver to ensure the procedure proceeds smoothly. Because the liver is located in the upper abdomen, it is adjacent to several vital organs and structures, such as the gallbladder, stomach, colon, kidneys, and major blood vessels. Some lobes of the liver are superficial and can easily cover other organs. Therefore, it is essential to maneuver the liver during the procedure to expose the surgical field.

[0010] Furthermore, the liver is large, soft, and has a rich blood supply; tearing the capsule can easily lead to intraoperative complications such as bleeding. The liver receives a large amount of blood flow, including from the hepatic artery and portal vein, and improper handling can damage it. Laparoscopic surgery relies on a camera system for visualization, which may not be as direct as open surgery, increasing the risk of accidental liver injury. Cirrhosis, liver tumors, or other liver diseases can alter the texture and structure of the liver, making it more susceptible to injury during surgery.

[0011] In laparoscopic surgery, the method of pushing the liver open requires careful design to ensure surgical safety and effectiveness. Currently, there are four main methods: First, using a retractor. Laparoscopic retractors, such as liver retractors or liver hooks, can pull the liver to one side to expose the underlying structures. However, this method may increase tension on the liver capsule, increasing the risk of tearing and bleeding. Second, patient positioning. Changing the patient's position, such as tilting the operating table, can utilize gravity to help push the liver open, but the effectiveness is limited by the function of the operating table and the patient's overall condition. Third, using liver suspension techniques. Sutures or special suspension straps are used to suspend a corner or portion of the liver to expose the surgical area. This method may require additional puncture holes, and excessive suspension may lead to compression and damage to liver tissue. Finally, placing a water cushion or inflatable balloon under the liver to manually push it open. These methods may require additional surgical steps, and the placement and removal of the water cushion or balloon increases surgical time. Therefore, current methods do not effectively address the issue of tissue damage during intraoperative liver opening.

[0012] Therefore, an instrument is needed during surgery that allows for easy and stable movement of the liver, providing sufficient tension or exposure of the surgical field without damaging the liver. Summary of the Invention

[0013] The purpose of this invention is to address the shortcomings of existing instruments used to push open the liver in laparoscopic surgery. This invention aims to provide a balloon-type pusher for use in laparoscopic surgery.

The trachea is connected to the balloon (and connected to an external air source). The connecting rod is inserted into the first rod and its two ends are exposed. One end of the connecting rod is rotatably connected to the upper side of the second rod, and the other end is rotatably connected to the pusher. The pusher is slidably connected to the handle.

[0016] Preferably, the first rod and the second rod are rotatably connected by a hinge.

[0017] Preferably, one end of the connecting rod is hinged to the upper side of the second rod body, and the other end is hinged to the pusher.

[0026] To make this utility model more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] A type of balloon-type pusher used in laparoscopic surgery, such as Figures 1-4As shown, it includes a first rod 1, a second rod 2, a handle 3, a balloon 4, an air tube 5, a connecting rod 6, and a pusher 7. The first rod 1 and the second rod 2 are hinged at their lower sides. The balloon 4 is fitted onto the second rod 2. The air tube 5 is connected to the balloon 4 and connected to an external air source. The connecting rod 6 is inserted into the first rod 1 with both ends exposed. The first end of the connecting rod 6 is hinged to the upper side of the second rod 2, and the second end of the connecting rod 6 is hinged to the pusher 7. The pusher 7 slides in the handle 3. Specifically, the handle 3 may have a sliding groove, and the handle 7 is installed in the sliding groove.

[0029] Working principle: When it is necessary to move the liver or other organs, the sliding pusher 7 drives the connecting rod 6 to move. Since the connecting rod 6 is hinged to the second rod 2, the connecting rod 6 pushes the second rod 2 to rotate, thereby realizing the bending movement, which makes it convenient for medical staff to push the liver or other organs with the side of the inflatable balloon 4.
