The invention relates to the technical field of medical instruments, in particular to clinical safe flushing equipment for anorectal surgery, which comprises a base, a bracket is arranged on the base, and a liquid storage tank and a bearing part are fixedly connected to the side wall of the bracket; a collecting assembly is arranged on the base, a flushing pipe used for flushing the rectum is arranged on the support, a pump assembly is arranged on the side wall of the liquid storage tank, an input port of the pump assembly is communicated with the bottom of the liquid storage tank, an output port of the pump assembly is communicated with a connecting pipe, and the connecting pipe is communicated with the flushing pipe. A flow control assembly is arranged on the flushing pipe; the flow control assembly comprises a sleeve, a flushing pipe is in sliding fit with the inner side wall of the sleeve, an adjusting groove is formed in the outer wall of the flushing pipe, and the depth of the adjusting groove becomes smaller from top to bottom; the inner side wall of the sleeve is fixedly connected with an annular protruding block, and the annular protruding block is connected outside the flushing pipe in a sleeving mode and is in sliding fit with the adjusting groove. And a protection assembly is arranged in the sleeve. Self-adaptive matching regulation and control of the insertion depth of the flushing pipe and the flushing flow can be achieved, and the safety and effectiveness of flushing operation are improved.

This invention discloses an automatic identification method for pelvic organ prolapse based on deep learning and the PCL line, comprising: S1: acquiring and preprocessing medical images of the pelvic floor region, and simultaneously annotating the bladder, uterus, rectum, and bony anatomical structures to construct a training dataset; S2: constructing and training a multi-objective deep learning segmentation model based on the training data to achieve automatic segmentation of the bladder, uterus, rectum, pubic symphysis, and the two vertebrae from the coccyx; S3: extracting the lowest edge point of the segmented pubic symphysis region and the highest edge point of the two vertebrae from the coccyx region to construct a set of bony key points; S4: connecting the bony key points to automatically generate the pelvic floor reference line (PCL line); S5: analyzing the spatial positional relationship of the bladder, uterus, and rectum relative to the PCL line to obtain the downward displacement feature information of the pelvic organs; S6: automatically determining the degree of pelvic organ prolapse based on the spatial positional relationship. This invention achieves automated identification of the degree of pelvic organ prolapse, reduces subjective errors caused by manual measurement, and improves the consistency, accuracy, and efficiency of the assessment.

This invention relates to a cutting device for cutting off the rectal end portion of an animal carcass, the cutting device comprising: a support member; a drilling member rotatably mounted on the support member, the drilling member including a tubular drilling wall portion surrounding an internal drilling space, the drilling wall portion having an open cutting end and a rear end opposite to the open cutting end; a centering mandrel arranged coaxially with the drilling wall portion, the mandrel having a guide end configured to enter the anal opening of the carcass, at least a portion of the mandrel being circumferentially surrounded by the drilling wall portion to define an annular space circumferentially surrounding the mandrel; and a suction device for applying suction to the internal drilling space via one or more inlet openings. The cutting device further includes one or more venting openings, which are different from the one or more inlet openings and different from the open cutting end, the one or more venting openings being configured to allow air to enter the internal drilling space.

The utility model provides a high-position anal dilatation device which comprises a lens cone, the front end of the lens cone is contained in the rectum of a human body, and an inclined opening is formed in the edge of the rear end of the lens cone in an inclined mode. Wherein the side surface of the lens barrel is provided with a groove-shaped opening, and the groove-shaped opening extends from the side surface of the lens barrel to the front end of the lens barrel; the endoscope core is located in the endoscope barrel, the chock plug of the endoscope core is exposed outside, the endoscope core is taken out and discarded after the endoscope barrel enters the anus, the front end of the chock plug is in the closed oval shape and can smoothly enter the rectum of the human body, the open design of the end opening of the front end of the endoscope barrel is combined with the groove-shaped opening, the exposed area of the rectum is directly increased, and the endoscope is convenient to use. By means of the design of the oblique opening, a height difference exists between the limiting plate of the lens barrel and the oblique opening, the lens core is convenient to extract, and the lens barrel is matched with a handle of the electronic anorectal inspectoscope, so that assembly interference is avoided.

According to the technical scheme, the protection support for the rectum anastomotic stoma is characterized in that the protection support comprises a supporting tube, the supporting tube is rotationally connected with a positioning tube and further connected with a moving tube in a threaded mode, and the moving tube is fixedly connected with a plurality of bending parts fixedly connected with the positioning tube. Through the arrangement of the bendable bending piece, the elastic intestinal wall can wrap the bent bending piece to enable the position of the bent bending piece to be relatively fixed, so that the position of the device is fixed when the intestinal tract is expanded and contracted, the bending of the bending piece is controlled through the movement of the moving piece, and the device is conveniently placed and removed.
