Description

Technical Field

[0001] The invention relates to an airbag-type pushing and stripping surgical forceps used in laparoscopic surgery, belonging to the technical field of medical instruments. Background Art

[0002] Medical forceps are often used during surgery. However, current forceps have sharp tips, which can easily damage organs within the abdominal cavity. For example, in addition to using forceps to grasp or seal tissue, laparoscopic surgery in the upper abdomen often requires the liver to be advanced. Because the liver is located in the upper abdomen, it is in close proximity to several vital organs and structures, such as the gallbladder, stomach, colon, kidneys, and major blood vessels. Some lobes of the liver are shallow and can easily obscure other organs. During surgery, the liver must be advanced to expose the surgical field. Furthermore, the liver is large, soft, and has a rich blood supply. A rupture of the capsule can easily lead to intraoperative complications such as bleeding. The liver receives a large blood flow, including from the hepatic artery and portal vein, and improper handling can damage it. Laparoscopic surgery relies on a camera-assisted field of view, which can be less intuitive than 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.

[0003] Therefore, in order to ensure the smooth progress of abdominal surgery, an instrument is needed during the operation that can easily and stably move the liver, provide sufficient tension or expose the surgical field, and not damage the liver. Summary of the Invention

[0024] To make the present invention more clearly understood, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] A kind of air bag type pushing and stripping surgical forceps used in laparoscopic surgery, such as Figures 1 to 5 As shown, it includes forceps 1, a first rod 2, a second rod 3, a handpiece 4, a knob 42, an inflatable balloon 5, and a trachea 6; wherein: the forceps 1 is connected to the end of the second rod 3, the other end of the second rod 3 is rotatably connected to the first rod 2, the forceps 1 is connected to the handpiece 4 through an opening and closing control structure and controls its opening and closing, the first rod 2 and the handpiece 4 are fixedly connected, the inflatable balloon 5 is integrally connected to the second rod 3, and is close to the end of the second rod 3 connected to the forceps 1, the two ends of the second rod 3 are exposed relative to the inflatable balloon 5, the trachea 6 is in communication with the inflatable balloon 5 and is connected to an external air source; the handpiece 4 is threadedly connected to the knob 42 for controlling the rotation of the inflatable balloon 5 within a certain angle range;

[0027] The knob 42 is connected to the handheld piece 4 near one end of the first rod body 2 by a threaded connection. The rotation of the knob 42 enables it to move forward and backward relative to the first rod body 2. The knob 42 is connected to the pull rod 10 inserted in the first rod body 2 through a first pulling mechanism (pulling wire or rod, not shown in the figure) and controls the bending rotation of the inflatable balloon 5. The pull rod 10 is inserted in the first rod body 2 and connected to the knob 42 at one end and exposed from the first rod body 2 and connected to one side of the second rod body 3 at the other end. The second rod body 3 is hinged to the first rod body 2 through the hinge shaft (hinge shaft) 7. The first end of the pull rod 10 is connected to the knob 42 through the first pulling mechanism. The second end of the pull rod 10 is hinged to the two hinge rods 9 at corresponding positions on both sides. The hinge rods 9 are inserted in the eccentric shaft 8. The two ends of the eccentric shaft 8 are connected to the two opposite sides of the second rod body 3 through the two connecting rods connected to the two ends. Thus, the forward and backward movement of the knob 42 drives the forward and backward displacement of the pull rod 10. The pull rod 10 pushes the hinge rod 9, thereby driving the displacement and rotational movement of the eccentric shaft 8. The displacement and rotation of the eccentric shaft 8 drive the movement and rotation of the integrally connected second rod body 3 and inflatable balloon 5, thereby realizing the bending movement of the inflatable balloon 5, as shown in Figures 2 to 4 .

[0028] The handheld piece 4 includes an operating handle 41 for controlling the opening and closing of the forceps 1. The operating handle 41 includes a fixed handle 411, a movable handle 412, and a handle seat 413. The knob 42 is connected to the handle seat 413. The fixed handle 411 is fixedly connected to the handle seat 413. The movable handle 412 is hinged to the handle seat 413 and connected to the forceps 1 through a pulling wire or rod 414. The movable handle 412 is configured to control the opening or closing of the forceps 1 when it is rotated in the direction close to the fixed handle 411 through the pulling wire or rod. The pulling wire or rod 414 is sequentially inserted in the first rod body 2 and the second rod body 3 and extended from the second rod body 3 to be connected to the forceps 1. The pulling wire or rod can be made of nickel-titanium metal alloy or stainless steel, as shown in Figure 5 .

[0029] Working principle: when it is necessary to push the liver or other organs, the knob 42 on the surgical forceps is controlled to drive the displacement of the connecting rod 10 through the pulling mechanism. The displacement of the connecting rod 10 drives the hinge rod 9 and the eccentric shaft 8, thereby realizing the bending movement of the second rod body 3 and the inflatable balloon 5. It is convenient for medical staff to push the liver or other organs with the side surface of the inflatable balloon 5. The opening and closing of the forceps 1 are consistent with the prior art and adopt a pull rod or steel wire structure.

[0030] The above-mentioned implementation cases are only preferred implementation cases of the present invention and are not any formal or substantial limitations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the present invention, and these improvements and supplements should also be regarded as the scope of protection of the present invention.
