[0025] A guide device for installing a single-hole multi-channel puncture device, comprising: a guide rod sleeve 1 and a guide rod core 2. The guide rod sleeve 1 is provided with a rubber ring hole 11, which passes through both ends of the guide rod sleeve 1. One end of the rubber ring hole 11 is a plug inlet, and the other end is a mounting port. The guide rod sleeve 1 is provided with a through hole 12 on one side of the rubber ring hole 11, and the through hole 12 extends to the plug inlet; one end of the guide rod core 2 is inserted into the guide rod sleeve 1 from the mounting port. When installing the puncture device, the rubber ring is pinched flat (in a straight line). Type), then insert the rubber ring into the rubber ring hole 11 from one end of the insertion entrance (the part of the puncture device connected to the rubber ring is inserted into the through hole 12) until the rubber ring is completely inserted into the rubber ring hole 11, and then insert one end of the guide rod sleeve 1 (the end of the insertion entrance) from the incision, and then push the guide rod core 2 into the guide rod sleeve 1, push the rubber ring out of the rubber ring hole 11 into the abdominal cavity, and then pull out the guide rod sleeve 1 and the guide rod core 2 to complete the installation of the puncture device, which is convenient and quick, and causes little damage to the incision.

[0026] like Figure 2 As shown, in order to facilitate holding of the device, the guide rod sleeve 1 is provided with a bell mouth 13 at one end of the mounting opening, and the suspended end of the guide rod core 2 is in a trumpet shape. The bell mouth 13 enlarges the end volume of the guide rod sleeve 1, making it easier to operate and hold, and anti-slip stripes can be provided on the outer side of the bell mouth 13 to further improve the comfort of operation.

[0027] like Figure 2 As shown, a limiting protrusion 21 is provided on the ring side of one end of the guide rod core 2 close to the plug entrance, and the limiting protrusion 21 is clamped in the through hole 12. In this way, the guide rod core 2 is clamped in the guide rod sleeve 1 to limit the guide rod core 2.

[0028] In order to further optimize, in order to prevent the puncture device rubber ring from being scratched by the guide rod sleeve 1 when entering the rubber ring hole 11, rounded corners are provided on both sides of the through hole 12 near the plug entrance, and the cross-section of the rubber ring hole 11 in the extension direction of the guide rod sleeve 1 is flat, so that it is more suitable for inserting a straight-line rubber ring.

[0029] In order to reduce production costs and improve production efficiency, the guide rod sleeve 1 and the guide rod core 2 are both made of plastic, wherein the guide rod sleeve 1 can be made of transparent material to facilitate observation of the positions of the inserted rubber ring and the guide rod core 2.

[0030] In summary, when installing the puncture device, flatten the rubber ring, and then insert the rubber ring into the rubber ring hole 11 from one end of the insertion port until the rubber ring is completely inserted into the rubber ring hole 11, and then insert one end of the guide rod sleeve 1 from the incision, and then push the guide rod core 2 into the guide rod sleeve 1, push the rubber ring out of the rubber ring hole 11 into the abdominal cavity, and then pull out the guide rod sleeve 1 and the guide rod core 2 to complete the installation of the puncture device, which is convenient and quick, and causes little damage to the incision.
