Description

Technical Field

[0001] The utility model relates to the technical field of gastrointestinal surgical medical instruments, in particular to a gastrointestinal surgical rectum fixation and pulling-out auxiliary device. Background Art

[0002] Gastrointestinal surgery is the gastrointestinal surgery department, which refers to the surgical department that specializes in the research and treatment of digestive system diseases, mainly involving diseases of the stomach, small intestine, large intestine, liver, gallbladder, pancreas and other organs. In the clinical practice of gastrointestinal surgery, medical staff generally pull out the patient's rectum and then treat the lesions in the rectum. When the medical staff pulls out the rectum, they will use a pulling-out auxiliary device to first absorb and fix the rectum through the pulling-out auxiliary device, then pull the rectum out, and then the medical staff will treat the lesions in the rectum.

[0003] For example, the authorization announcement number "CN219461795U" is named a gastrointestinal surgery rectal fixation and traction auxiliary device. Although the horizontal position of the adsorption component can be adjusted by the telescopic connecting component, thereby realizing the rapid adjustment of the horizontal position of the adsorption component and effectively increasing the application scope of the traction auxiliary device, the existing gastrointestinal surgery rectal fixation and traction auxiliary device adopts a rectal adsorption structure fixed straight up and down at the front end of the locking rod to suck out and fix the rectum of the gastrointestinal surgery patient by vacuum air pressure suction. However, in actual operation, the patient usually lies on the operating table, and the straight up and down rectal traction auxiliary structure can only traction the patient's rectum directly below. Once the patient is inconvenient to lie in a posture facing the rectal traction auxiliary device due to illness or injury, the use of the gastrointestinal surgery rectal fixation and traction auxiliary device will be restricted, thereby affecting the use effect of the existing gastrointestinal surgery rectal fixation and traction auxiliary device.

[0004] Meanwhile, the existing gastrointestinal surgery rectal fixation and traction auxiliary device, although the lower end uses a rectal traction auxiliary structure that can be clamped and fixed on the operating table and can slide up and down to adjust, the distance between the rectal adsorption part of the rectal traction auxiliary structure and the rear fixed column is relatively long, and the top is manually adjusted and fixed for fixation. Once the manual rotating wheel is accidentally touched or loosened, the rectum of the patient being pulled out and fixed will be vibrated and pulled to a certain extent. Because the rectum is a part of the internal organs of the human body, the rectum is extremely fragile and the unstable supporting structure can easily cause secondary injuries, thereby reducing the safety and stability of the use of the gastrointestinal surgery rectal fixation and traction auxiliary device.

Then the two side plug rods 42 are inserted into the reserved holes 41 and the corresponding inner sides of the sliding block 3, so that the height of the sliding block 3 can be locked. The two side auxiliary rods 43 will be supported on both sides of the hydraulic cylinder 45 by two supporting frames 44, so that the connection between the hydraulic cylinder 45 and the sliding block 3 is more firm and tight, and the problem of active shaking is not easy to occur. At the same time, connecting the power supply can activate the hydraulic cylinder 45, and the hydraulic cylinder 45 will push the front end pull-out tube 8 to change its horizontal position length;

[0041] The pull-out tube of the gastrointestinal surgery rectal fixed pull-out auxiliary device has the following structure for adjusting the rectal pull-out angle:

[0042] The pull-out tube 8 is connected and fixed by the locking bolt 63 between the connecting block 61 and the rotating block 62. When the angle of the pull-out tube 8 is not enough to meet the treatment requirements, the operator can select the locking bolt 63 to separate the rotating block 62 and the connecting block 61, and then manually adjust the pull-out tube 8 to a suitable angle position, and then screw the locking bolt 63 back between the rotating block 62 and the connecting block 61 to fix it, and the angle adjustment operation can be completed;

[0043] The sterile gasket 54 is made of a clean and hygienic medical rubber material, so that the sterile gasket 54 can play a protective role when it contacts the rectum for pulling out. When the rectum needs to be pulled out, the bottom end of the pulling-out tube 8 is aligned with the patient's rectum, and then the pulling plate 51 is lifted upward. At this time, the piston plate 53 inside the pulling-out tube 8 will use the suction force of the air pressure vacuum to absorb and pull out the rectum, and the exhaust hole 55 will discharge the air squeezed up by the piston plate 53. When the rectal treatment is completed, in order to reduce the damage to the rectum reset and loosening, the sealing plug 64 is pulled out, and the sealing plug 64 will not be pressed against the inner side of the air inlet 65. The air inlet 65 delivers air from the lower end to the inside of the pulling-out tube 8 to balance the air pressure so that the rectum can fall naturally.
