Embodiment 1

[0039] The sealing member 30 in this embodiment is a sealing block 31 made of elastic material. see image 3 , in the initial state, the sealing block 31 is arranged laterally in the ventilation passage 21 in the ventilation part 20, and there is an interference fit between the sealing block 31 and the ventilation passage 21, that is, all edges of the sealing block 31 fully abut against the ventilation part 20 to seal the vent passage 21. The transverse direction is a direction perpendicular to the axial direction of the air passage 21 . see Figure 4 , when the gas injection part 10 is installed on the ventilation part 20, the gas outlet end 111 of the gas injection pipe 11 exerts a thrust on the part of the sealing block 31, so that the sealing block 31 produces elastic deformation, and the gap between the sealing block 31 and the inner wall of the ventilation part 20 A gap is formed so that the gas injection channel 113 in the gas injection tube 11 communicates with the ...

Embodiment 2

[0041] The sealing member 30 in this embodiment includes a sealing block 31 and an elastic member 32, the sealing block 31 is made of non-elastic material, the elastic member 32 is preferably a shrapnel, and the outer diameter of the sealing block 31 is equal to or slightly larger than the inner diameter of the ventilation member 20, One end of the elastic member 32 is fixed on the wall of the ventilation channel 21 , and the other end of the elastic member 32 is connected with the sealing block 31 . see Figure 5 , in the initial state, under the action of the elastic member 32 , the sealing block 31 is arranged laterally in the air passage 21 to seal the air passage 21 . see Figure 6 , when the gas injection part 10 is installed on the ventilation part 20, the gas outlet end 111 of the gas injection pipe 11 exerts a thrust on the sealing part 30, so that the elastic part 32 produces elastic deformation, and drives the sealing block 31 to rotate, so that the sealing block 3...

Embodiment 3

[0043] see Figure 7 , the breather 20 in this embodiment includes a first breather 22 and a second breather 23, the second breather 23 is partly located in the first breather 22, and the second stopper 25 is a protrusion formed on the second One end of the ventilation element 23 is located in the first ventilation element 22 . The first stop portion 24 is arranged at one end of the first breather 22 and is arranged in a ring shape, and the middle opening of the ring is for the gas outlet end 111 of the gas injection tube 11 to pass through. A ventilation channel 21 is provided in the first ventilation part 22 , and a ventilation channel 21 is also provided in the second ventilation part 23 . Both the second stopper portion 25 and the sealing member 30 are disposed in the ventilation channel 21 of the first ventilation member 22 . The ventilation channel 21 in the second ventilation part 23 communicates with the inner cavity of the casing storehouse 40 .

Abstract

The invention discloses an air injection assembly of a surgical instrument and a puncture outfit. The air injection assembly of the surgical instrument includes an air injection part and a ventilationpart which are selectively connected; the air injection part includes an air injection channel, and the ventilation part includes a ventilation channel; a sealing part capable of producing elastic deformation is arranged in the ventilation channel; when the air injection part and the ventilation part are separated, the sealing part seals the ventilation channel; and during and / or after the connection of the air injection part and the ventilation part, at least part of the sealing part is elastically deformed under the action of external force to release the sealing of the ventilation channel,and the air injection channel communicates with the ventilation channel. The puncture outfit includes the air injection assembly. The air injection part only needs to be installed on the ventilationpart of the puncture outfit needing of air injection, and the puncture outfit which does not need of air injection is no longer provided with the air injection part, so that the structure and manufacturing process of a single puncture outfit are simpler. Meanwhile, the operation space integrally occupied by multiple puncture outfits during an operation is reduced, which is more conducive to the surgical operation of a doctor.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to an air injection component and a puncturer, and belongs to the field of medical equipment. Background technique [0002] A trocar is a surgical instrument used to establish access to the abdominal cavity, including a puncture core and a puncture sleeve. In the specific operation process, the doctor generally opens a small opening in the patient's abdomen, and then aligns the puncture core of the puncture device with the small incision and moves downward while reciprocating and rotating, thereby driving one end of the puncture sleeve into the patient's abdominal cavity. After the puncture is completed, the puncture core is pulled out from the puncture sleeve, and the puncture sleeve forms a passage for other surgical instruments to enter and exit. In order to expand the space of the abdominal cavity and increase the distance between the various tissues, which is more conducive to the oper...
