Detailed Description
In the following detailed description of the present invention, reference is made to the accompanying drawings, wherein the components are described in the embodiments with reference to the position shown in the drawings, and the description is not intended to limit the components to the position shown.
A negative pressure gun ligation device capable of laterally sucking is characterized by comprising a piston sleeve assembly, an L-shaped suction head assembly, a rubber ring and a deflector rod assembly, wherein the piston sleeve assembly is used for generating negative pressure and adjusting the size of the negative pressure, the L-shaped suction head assembly is communicated with the piston sleeve assembly to suck a tissue focus, the rubber ring is sleeved on an elbow and used for ligating the tissue focus, and the deflector rod assembly is used for enabling the rubber ring to be separated from the elbow; the L-shaped suction head component comprises an L-shaped suction head (14) for accommodating a tissue focus and a ventilation straight pipe (12); the deflector rod assembly comprises a rubber ring excitation curved rod (10), a transmission rod (11) and a deflector rod (13).
Specifically, as shown in fig. 1, the main components of the piston-sleeve assembly include a sleeve (6), a piston (7) accommodated in the sleeve (6), and an adjusting assembly for driving the piston (7) to move along the sleeve (6) to adjust the relative negative pressure, i.e., a handle (1), a screw (2), a nut (3), a nut (4), and a piston fixing end (5); in order to realize quantitative adjustment of the relative negative pressure, the handle (1) is fixedly connected with the screw rod (2), and when the quantitative adjustment device is used, the handle (1) is rotated, and the piston (7) moves backwards along the sleeve (6) under the action of the screw rod (2), the nut (4) and the piston fixing end (5).
In order to ensure that the relative negative pressure generated by the piston sleeve assembly is between 0.08 MPa and 0.1MPa and avoid the injury of the intestinal wall muscle layer caused by excessive and deep tissue suction due to excessive suction of the traditional ligation suction, the diameter of the piston is 25 to 30mm, and the length of the sleeve is 80 to 85 mm.
Specifically, the ventilation straight pipe (12) is communicated with the sleeve (6) through a gas hose (9), in order to form lateral suction on a tissue focus, the gas hose (9) is positioned at a gas outlet on the ventilation straight pipe (12), and the gas hose (9) is a PU pipe; in order to reduce the plane tissue damage caused by unnecessary transverse caliber, the elbow is in a fusiform shape.
