Problems solved by technology

[0002] Existing peritoneal puncture and drainage is mainly seldinger puncture technique, in which the guide wire used has no protection device, and when the puncture device is used for puncture, the puncture device is easy to touch and damage the organs inside the abdominal cavity, causing secondary damage; and The existing puncture device is in the shape of a thin tube with a small diameter and complicated operation. It is impossible to place a thick double cannula with good drainage, and the drainage effect is poor.

Embodiment 1

[0025] This embodiment provides a drainage puncture forceps, such as figure 1 As shown, it includes a pliers body 1 and a pliers head 2. The pliers body 1 and the pliers head 2 are connected by a pliers shaft 3. The pliers head 2 is a tapered pliers head. A drainage tube through hole 4 is arranged in the pliers head 2. It includes symmetrically arranged first half pliers 21 and second half pliers 22, the contact surface of the first half pliers 21 and the second half pliers 22 is a plane, and the through hole 4 of the drainage tube is symmetrically arranged on the first half pliers 21 and the second half of the pliers head 22 , the through hole 4 of the drainage tube passes through the pliers shaft 3 from one end of the pliers head 2 along the length direction of the pliers head 2 and extends to the other end of the pliers head 2 .

[0026] The drainage puncture forceps of this embodiment can be made into different models, adapt to different drainage tubes, and be used under t...

Embodiment 2

[0031] This embodiment provides a drainage puncture device, such as figure 1 , 3 , 4, including the guide wire 5 and the drainage puncture forceps in the first embodiment, the diameter of the guide wire 5 is smaller than the diameter of the drainage tube through hole 4, and the front portion of the guide wire 5 is provided with a positioning protrusion 51, and the positioning protrusion 51 The outer diameter is greater than the outer diameter of the pliers head 2 front ends.

[0032] The positioning protrusion 51 is a spherical positioning protrusion.

[0033] The positioning protrusion 51 is 8 cm away from the front end of the guide wire.

[0034] The part from the front end of the guide wire 5 to the positioning protrusion 51 is made of soft material, which will not cause damage to the organs and tissues in the abdominal cavity, and is safe to use.

[0035] The drainage and puncture device in this embodiment is used under the guidance of color ultrasound or CT. When using...
