[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-4 The utility model provides a technical solution: a disposable Veress needle clamping device, comprising a Veress needle body 1, and a handle 101 arranged at the top end of the Veress needle body 1;

[0029] The pneumoperitoneum needle body 1 is slidably connected to the inside of the horizontal plate 2. Two vertical plates 201 are connected to the top of the horizontal plate 2. The outer walls of the two vertical plates 201 are commonly connected to a handle 202. A movable block 203 is slidably connected to the outer wall of any vertical plate 201. The pneumoperitoneum needle body 1 is slidably connected to the inside of the movable block 203. A rubber ring is provided inside the movable block 203 to increase the friction between the pneumoperitoneum needle body 1 and the outer wall of the handle 202. The palm of the hand is placed against the outer wall of the handle 202, the fingers hold the two vertical plates 201, the horizontal plate 2 is placed against the entry point of the patient's skin, and then the pneumoperitoneum needle body 1 is inserted into the movable block 203 so that the bottom end of the handle 101 is placed against the surface of the movable block 203, thereby playing a preliminary positioning role for the pneumoperitoneum needle body 1.

[0030] A fixing groove 301 is provided inside the horizontal plate 2, and a latex block 302 is connected to the inner wall of the fixing groove 301. The Veress needle body 1 enters the movable block 203 and moves downward until the bottom end of the Veress needle body 1 moves through the fixing groove 301 and fits against the inner wall of the latex block 302. Under the action of the latex block 302, the Veress needle body 1 of different diameters can be closely fitted, thereby playing a role in positioning and clamping the Veress needle body 1.

[0031] An anti-backward movement mechanism is provided inside any vertical plate 201 to prevent the pneumoperitoneum needle body 1 from moving back during the downward movement, thereby causing gas leakage. At the same time, it can reduce the pneumoperitoneum needle body 1 from accidentally injuring the patient's abdominal organs and causing unnecessary harm to the patient.

[0032] Scale lines are provided on the outer wall of any vertical plate 201, and the length of the pneumoperitoneum needle body 1 entering the patient's body can be accurately understood through the scale lines.

[0033] Each vertical plate 201 is provided with a gripping groove to facilitate the doctor's hand to grasp the vertical plate 201.

[0034] The outer wall of the grip 202 is configured to be arc-shaped so as to better fit the curvature of the doctor's palm.

[0035] The anti-backward movement mechanism includes a wedge block 1 4, a wedge block 2 401 and an elastic member;

[0036] A plurality of wedge blocks 4 are equidistantly and slidably connected inside any vertical plate 201, and a wedge block 2 401 is connected to the outer wall of the movable block 203. The wedge block 2 401 fits in contact with the outer wall of any wedge block 1 4. An elastic member is provided on the outer wall of each wedge block 1 4. The downward movement of the pneumoperitoneum needle body 1 drives the wedge block 2 401 connected to the movable block 203 to move downward synchronously, thereby squeezing the wedge block 1 4, so that the wedge block 1 4 is squeezed into the interior of the vertical plate 201, and the wedge block 2 401 moves downward. Under the action of the elastic member, the squeezed wedge block 1 4 can rebound, and the bottom end of the wedge block 1 4 and the top end of the wedge block 2 401 abut against each other, thereby preventing the movable block 203 from moving back, and further preventing the pneumoperitoneum needle body 1 from moving back.

[0037] The elastic member includes a fixing block 402 and a spring 403;

[0038] A plurality of fixed blocks 402 are equidistantly connected to the outer wall of the vertical plate 201, and a spring 403 is connected to the inner wall of each fixed block 402. The other end of each spring 403 is connected to the outer wall of the wedge block 4. The wedge block 4 is squeezed and slides inside the vertical plate 201 into the interior of the fixed block 402, so that the spring 403 is squeezed. Under the elastic action of the spring 403, the wedge block 4 can be pushed to quickly return to its original position.

[0039] The outer wall of each wedge block 4 is connected to a pull rope 404, and each pull rope 404 is slidably connected to the inside of the fixed block 402. By pulling the pull rope 404, the wedge block 4 can be moved into the inside of the fixed block 402, so that the doctor can lift the pneumoperitoneum needle body 1 that is too deep, so that the movable block 203 can continue to abut against the handle 101, thereby supporting the handle 101.

[0040] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
