The shape and the size of the lead-in pipe 2 are matched with the pipe diameter of the poking card, the lead-in pipe 2 can be inserted into the poking card with a common diameter, and a plugging part 3 is arranged at the inlet of the lead-in pipe 2 and used for sealing the lead-in pipe 2 so as to keep the lead-in pipe in an expansion state; among them, the trocar (trocar) is a common instrument used in surgery, and the structure thereof is not described herein.

The matching structure of the leading-in pipe 2 and the capsule body 1 in the contraction state can be sent to the position to be operated through a poking card, and the capsule body 1 in the expansion state can push the target organ to expose the operation position.

In the intraoperative visceral organ push capsule in the embodiment, the matching structure of the capsule body 1 and the guide-in tube 2 in the contraction state can be sent into a body cavity through the poking card, so that the poking card can conveniently place and take out the capsule body 1; after being placed in a preset area, a proper amount of gas or normal saline is injected into the capsule body 1 through the inlet of the introducing pipe 2, the volume and the shape of the balloon are adjusted according to the operation requirement, after the capsule body 1 reaches a target expansion state, the inlet of the introducing pipe 2 is sealed by using the plugging part 3, the air leakage and the liquid leakage of the capsule body 1 are prevented, and the target visceral organ is dynamically pushed by using the capsule body 1 in the expansion state; the use is convenient, and the bag body 1 does not need to be additionally bundled.

As an alternative embodiment, the length of the balloon body 1 allows the ligating clip 4(hem-o-lok clip) to occlude at least a portion thereof to adjust its volume in the self-expanding state.

In order to adjust the volume of the capsule body 1 in an expansion state on the premise of not changing the expansion degree of the capsule body 1 according to actual requirements, the extension length of the capsule body 1 is mainly reduced; the bag body 1 in this embodiment should be provided as an elongated bag having a certain extending length to allow the hem-o-lok clip to pinch at least part of the bag body 1 at different positions of the bag body 1 in the extending direction of the bag body 1. Referring to fig. 2, when a small-volume capsule body 1 is actually needed, the left half of the capsule body 1 is clamped by hem-o-lok, and only the right half is communicated with the introducing pipe 2.
