During use, it is easy to cause uneven adsorption force, damage the gastrointestinal tissue, and affect the patient's later recovery.

[0003] In order to overcome the above-mentioned defects, the prior art (application number CN201822092815.3, Chinese patent application filed on 2018-12-13) is a laparoscopic negative pressure gastrointestinal lifting device, which can evacuate the inner cavity of the telescopic hose through the structural design of the air pump and the telescopic hose, and then the opening can be evacuated through the structural design of the connecting tube and the second inner rod, so that the opening can adsorb the patient's stomach or intestines; there is also prior art (application number CN202310502009.1, Chinese patent application filed on 2023-05-06) a laparoscopic surgery negative pressure gastrointestinal lifting device, which is provided with two relatively rotating splints, and a suction cup is provided on the inner side of the splint. The suction cup clamps the gastrointestinal tract while adsorbing, so that the fixation is more firm and prevents it from falling off; the cooperation of the first connecting rod and the second connecting rod can adjust the angle of the gastrointestinal tract clamped by the splint, which is convenient for medical staff to operate and move The support block can adjust the horizontal height of the splint of the device, which is convenient for adjusting the gastrointestinal lifting distance; and the prior art (Chinese patent application with application number CN202211095745.1 and application date 2022-09-08) is a laparoscopic surgical negative pressure gastrointestinal lifting device, which drives the splint to move upward by rotating the threaded rod, and then clamps the device on the operating table through the splint and the support base, pulls the movable plate to drive the insertion rod to move, so that the insertion rod leaves the slot, and then the support plate can be rotated to adjust the position of multiple negative pressure suction cups, which is easy to install and adjust; although the prior art can complete gastrointestinal adsorption, during the working process, the expanded adsorption holes are easily excessively adsorbed on the patient's gastrointestinal tissue, causing damage to the gastrointestinal tissue, and multiple sets of adsorption mechanisms acting on the negative pressure tube are easily bent due to the contraction of the gastrointestinal tissue and the softness of the negative pressure tube, affecting the negative pressure adsorption effect and causing squeezing damage to the gastrointestinal tissue.
