Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to a liposuction gun which is convenient for controlling the opening and closing of a negative pressure hole. Background Art

[0002] The liposuction gun, also known as the liposuction handle, is a device connected between the liposuction needle and the negative pressure tube to facilitate the operator to hold and control the liposuction needle. Figure 1 As shown, one end of the existing liposuction gun is a liposuction needle interface for detachably connecting the liposuction needle, and the other end is a negative pressure tube interface for detachably connecting the negative pressure tube. A negative pressure hole communicating with the inside and outside is opened near the liposuction needle interface on the side wall of the liposuction gun. During negative pressure liposuction, the operator holds the liposuction gun and controls the opening and closing of the negative pressure hole with the fingertips to control the negative pressure effect.

[0003] When using the existing liposuction gun, the opening and closing of the negative pressure hole can only be controlled by the fingertips, which is inconvenient. Especially when performing continuous negative pressure liposuction, the negative pressure hole needs to be continuously blocked with the fingertips, which is laborious. Utility Model Content

[0014] The liposuction gun is provided with a seesaw valve on the outer wall of the gun body to control the opening and closing of the negative pressure hole. In the initial state, under the tension of the V-shaped torsion spring, the sealing rubber plug abuts against the outer wall of the gun body to block the outlet of the negative pressure hole. When the negative pressure hole needs to be opened, the operator holds the gun body and presses down the right end of the seesaw with the thumb to make the left end of the seesaw tilt upward, and the sealing rubber plug is separated from the outer wall of the gun body, thereby opening the outlet of the negative pressure hole.

A negative pressure hole 1.3 communicating with the inside and outside is provided on the side wall of the gun body 1 near the negative pressure tube interface 1.2;

[0025] like Figures 2 to 6 As shown, the seesaw valve 3 is composed of a seesaw 3.1, two first orifice plates 3.2, two second orifice plates 3.3, a hinge shaft 3.4, a V-shaped torsion spring 3.5 and a sealing rubber plug 3.6;

[0026] Two first orifice plates 3.2 are fixed (welded or integrally formed) on the middle bottom surface of the seesaw 3.1 and are spaced apart from each other; two second orifice plates 3.3 are fixed (welded or integrally formed) on the outer side wall of the gun body 1 and are spaced apart from each other from each other. Specifically, the two second orifice plates 3.3 are located on the right side of the negative pressure hole 1.3; the two first orifice plates 3.2 are arranged between the two second orifice plates 3.3, and the two first orifice plates 3.2 and the two second orifice plates 3.3 are hingedly connected by a hinge shaft 3.4. Specifically, the hinge shaft 3.4 is composed of a screw and a nut, which is convenient for disassembly and assembly;

[0027] A V-shaped torsion spring 3.5 is mounted on the hinge shaft 3.4, and the V-shaped torsion spring 3.5 is located between the two first orifice plates 3.2; the outer wall of the gun body 1 and the bottom surface of the right end of the rocker plate 3.1 are provided with a limiting groove 6, both ends of the V-shaped torsion spring 3.5 are bent into an L shape, and the ends of the V-shaped torsion spring 3.5 are respectively installed in the two limiting grooves 6, and the limiting grooves 6 can be used to limit the ends of the V-shaped torsion spring 3.5, thereby improving the stability of the V-shaped torsion spring 3.5; specifically, the width of the limiting groove 6 is slightly larger than the end diameter of the V-shaped torsion spring 3.5, and when the V-shaped torsion spring 3.5 is pressed or opened, its end can slide adaptively in the limiting groove 6, and the end of the V-shaped torsion spring 3.5 can be prevented from detaching from the limiting groove 6;

[0028] like Figure 5 As shown, a sealing plug 3.6 for sealing the negative pressure hole 1.3 is installed on the bottom surface of the left end of the seesaw 3.1. In the initial state, under the tension of the V-shaped torsion spring 3.5, the sealing plug 3.6 abuts against the outer wall of the gun body 1 to seal the outlet of the negative pressure hole 1.3.

[0029] Preferably, in this embodiment, the sealing rubber plug 3.6 is made of rubber or silicone and has elasticity. Under the tension of the V-shaped torsion spring 3.5, the sealing rubber plug 3.6 can tightly seal the outlet of the negative pressure hole 1.3.

[0030] Preferably, in this embodiment, Figure 5As shown, a limiting column 3.7 is fixed to the bottom surface of the left end of the seesaw 3.1, and the sealing plug 3.6 is sleeved on the limiting column 3.7, which can facilitate the disassembly and assembly of the sealing plug 3.6 and the replacement of the sealing plug 3.6; specifically, the inner wall of the sealing plug 3.6 and the outer wall of the limiting column 3.7 have an interference fit, and a certain external force needs to be applied to remove the sealing plug 3.6 to prevent the sealing plug 3.6 from falling off easily; in addition, the sealing plug 3.6 and the limiting column 3.7 can also be fixed by adhesive to improve the stability of the sealing plug 3.6.

[0034] When the liposuction gun is in use, the liposuction needle 2 is installed at the liposuction needle interface 1.1 at the left end of the gun body 1, and the negative pressure tube interface 1.2 at the right end of the gun body 1 is connected to the negative pressure tube. The operator holds the middle section of the gun body 1 with his hand, and his thumb can press down the right end of the seesaw 3.1;

[0035] In the initial state, the operator's thumb does not press down the seesaw 3.1, and under the tension of the V-shaped torsion spring 3.5, the sealing rubber plug 3.6 tightly seals the outlet of the negative pressure hole 1.3, and under the negative pressure suction of the negative pressure device, liposuction is performed using the liposuction needle 2;

[0036] When the negative pressure hole 1.3 needs to be opened, the operator presses down the right end of the seesaw 3.1 with his thumb, so that the left end of the seesaw 3.1 tilts upward, and the sealing plug 3.6 is separated from the outer wall of the gun body 1, thereby opening the outlet of the negative pressure hole 1.3;

[0037] The negative pressure hole 1.3 is opened and closed by controlling the seesaw valve 3 with the thumb, which is convenient to operate, especially during continuous negative pressure liposuction. When the thumb is released, the sealing plug 3.6 continues to seal the negative pressure hole 1.3 under the tension of the V-shaped torsion spring 3.5, and the thumb can be released, which is labor-saving. In the prior art, there is air leakage when sealing the negative pressure hole 1.3 with the thumb. In this embodiment, the sealing plug 3.6 tightly seals the negative pressure hole 1.3 under the tension of the V-shaped torsion spring 3.5 of the seesaw valve 3, which can improve the sealing effect of the negative pressure hole 1.3 and prevent air leakage.
