Description

Adjustable anus dilator for gastrointestinal surgery Technical Field The invention belongs to the field of medical appliances, and particularly relates to an adjustable anus dilator for gastrointestinal surgery. Background In gastrointestinal surgery for examination, diagnosis or surgical treatment, it is often necessary to use an anal dilator to prop open the patient's anus, thereby obtaining a clear view and a safe operating channel for accurate diagnosis and treatment. The patent with the publication number of CN213527062U discloses a novel adjustable anus dilator for gastrointestinal surgery, which is characterized by comprising an expansion mechanism, a supporting plate and a supporting sleeve, wherein the expansion mechanism comprises a spreader, a shaft rod and a holding tube, the spreader comprises a movable disc I, a movable disc II, a movable rod I and a movable rod II, the movable rod I is hinged with the movable disc I and then is hinged with the movable rod II, the movable rod II is hinged with the movable disc II, four movable rods I and II form the spreader, the two spreader are sleeved on the shaft rod, the holding tube is in threaded connection with the shaft rod, the supporting plate is an arc-shaped strip on the upper surface, the lower bottom surface of the supporting plate is provided with a raised rectangular plate which is hinged with the movable rod II, the lower surface of the supporting plate is provided with a sliding groove which is in sliding connection with the movable rod II of the other spreader, and the supporting sleeve is an elastic rubber sleeve and is sleeved on the outer surfaces of the four supporting plates. The patent is used for dilating anorectal after gastrointestinal surgery, relieving anorectal contraction, stimulating defecation and the like. However, the above technical solution has the following disadvantages in the practical application process: In order to avoid the anus dilator from grinding the anus of a patient into bleeding, medical staff can smear lubricating oil on the surface of the anus dilator, so that the friction force between the anus dilator and the anus is reduced. However, when medical staff smears lubricating oil on the surface of the anus dilator, the lubricating oil is easy to smear uniformly due to careless operation, so that dead angles of smearing appear, and the anus of a patient is still likely to be worn out during subsequent use. And after the anal dilator enters the anal canal, lubricating oil on the surface of the anal dilator can be quickly absorbed by mucous membrane and is mixed with tissue fluid to be diluted, so that the lubricating effect is quickly reduced in the operation process. Since the anal dilator is already located in the patient, it cannot be effectively supplemented at this time. When the anus dilator is withdrawn, the surface of the anus dilator is in a state of insufficient lubrication and even dryness, and the anus and the anal canal of a patient are easily damaged. Disclosure of Invention In order to overcome the defects in the prior art and solve at least one technical problem in the background art, the invention provides an adjustable anus dilator for gastrointestinal surgery. The invention solves the technical problems by adopting the technical scheme that the adjustable anus dilator for gastrointestinal surgery comprises a mounting plate and a lubricating oil tank, wherein one side of the mounting plate is fixedly connected with a handle, one side of the mounting plate is fixedly connected with a plurality of first fixing rods, one end of each fixing rod is fixedly connected with an adjusting plate, a plurality of sliding grooves are uniformly formed in the adjusting plate along the circumferential direction, an adjusting rod is slidably connected at the sliding grooves, one end of each adjusting rod is fixedly connected with an expansion plate, and a plurality of oil outlets are formed in the expansion plate; The device also comprises an inner lubricating assembly and an outer lubricating assembly; The inner and outer double lubrication assembly comprises a rotating plate which is arranged on one side of the bottom of the mounting plate in a rotating mode, a splash-proof shell is connected to one side of the rotating plate in a sliding mode, a ring-shaped pipe II is fixedly sleeved on the splash-proof shell, a plurality of spray heads I are arranged on the ring-shaped pipe II in the circumferential direction, the spray heads I penetrate through the splash-proof shell, a handle is arranged in the middle of one side of the adjusting plate in a rotating mode, a plurality of connecting rods are arranged on one end face of one side of the handle in a sliding mode in the circumferential direction, a long pipe is fixedly connected to one end of each connecting rod, and a plurality of spray heads II are arranged on one side of the long pipe. Preferably, one end of the adjusting rod is fixedly connected with a gui
