Description

A vertical colonoscope training model

Technical Field

The present application relates to the field of medical training models, and in particular to a vertical colonoscopy training model.

Background technique

Colonoscopy is the most widely used and effective method of polyp screening today. Through colonoscopy, the mucosal state of the anal canal, rectum, sigmoid colon, descending colon, transverse colon, ascending colon, ileocecal region and terminal ileum can be observed sequentially and clearly. The instrument (colonoscope) used is a long electronic colonoscope. Through the electronic camera installed at the front end of the colonoscope, the image of the colon mucosa is transmitted to the electronic computer for processing, and finally displayed on the monitor screen. Through the screen, the doctor can observe the changes in the large intestine mucosa. For example, whether there are polyps or tumors. At the same time, the biopsy forceps or snares can be inserted through the instrument channel of the colonoscope to clamp or snare the polyp tissue, and finally the polyp tissue is pathologically sectioned for further examination.

There are currently three main methods for colonoscopy training: 1. Clinical patients, that is, using colonoscopy to conduct training on real patients; 2. Silicone simulated colon model, that is, a simulated colon model made of soft silicone; 3. Pig intestine model, and the complete pig intestine organ obtained by separating the pig intestine, which can be used for simulation training.

Regarding the above-mentioned related technologies, when a silicone simulated colon model is used for training, the simple silicone colon model is quite different from the actual colonoscopy operation environment. In order to optimize the training effect, the applicant designed a vertical colonoscopy training model with a higher degree of simulation.

Utility Model Content

In order to improve the simulation degree of the colonoscopy training model and optimize the training effect, the present application provides a vertical colonoscopy training model.

The present application provides a vertical colonoscope training model that adopts the following technical solutions:

A standing colonoscope training model comprises a colon model, a humanoid shell and a base; the colon model is installed in the humanoid shell, an inspection hole is provided through the humanoid shell, and the anus segment of the colon model is installed in the inspection hole; a shelf groove is provided on the base corresponding to the side contour of the humanoid shell, and the humanoid shell is placed in the shelf groove to keep the human body in a lateral position.

By adopting the above technical solution, the human body-mimicking shell simulates the patient's body and fixes the colon model inside. The base is used to maintain the upright state of the human body-mimicking shell to simulate the lateral position that the patient often maintains during examination. In this way, the position of the colon in the patient's body during colonoscopy examination can be more realistically simulated with a higher degree of simulation.

Optionally, it also includes a strap, which is fixed on the base and is used to fix the human body simulation shell.

By adopting the above technical solution, the humanoid shell is stably fixed on the base with straps, which facilitates the inspection of the colon model during training.

Optionally, a strap insertion slot is provided on the base corresponding to the strap, and the strap passes through the strap insertion slot and then binds the human body simulation shell.

By adopting the above technical solution, the straps can be easily disassembled and assembled, and the base, the straps and the human body-imitation shell can be easily disassembled and stored.

Optionally, an annular airbag is sleeved on the anus segment of the colon model, and the airbag is located on the anus segment; an air inlet pipe is provided on the airbag, and the air inlet pipe passes through the human body simulation shell; and also includes a valved pipe installed at the end of the air inlet pipe.

By adopting the above technical solution, the airbag is set on the anus segment, and the contraction force of the human anus is simulated by inflating the anus segment; the tightness of the anus segment can be adjusted by inflation/deflation, so as to be similar to the function of the anal sphincter of the real human body, so as to achieve a closed state in the intestinal cavity during colonoscopy, and the airbag can prevent gas from leaking from the simulated anus. The valved pipe can close the air inlet pipe and maintain the pressure of the airbag.

Optionally, the human-like shell includes a main body and a cover; the main body imitates the contour of a human torso, and an installation cavity is opened at the abdominal position of the main body corresponding to the size of the colon model; the cover is a cover body corresponding to the opening size of the installation cavity, and the cover is detachably mounted on the main body.

By adopting the above technical solution, the colon model in the installation cavity can be replaced and maintained by opening the cover, so that the training model can be used repeatedly.

Optionally, the cover is a transparent observation cover; it also includes a peritoneal membrane, which is installed between the colon model and the cover; elastic buckles are installed on the circumferential side of the peritoneal membrane, and matching buckles are provided on the cavity wall of the installation cavity corresponding to the elastic buckles.

By adopting the above technical solution, the peritoneal membrane can simulate the basic functions of real human peritoneal tissue, which not only reduces the possibility of intestinal bulging during colonoscopy, but also blocks the endoscopist's view of the intestine, ensuring the real simulation effect of colonoscopy.

Optionally, the peritoneal membrane is made of soft cloth with elasticity and expansion function.

By adopting the above technical solution, the peritoneal membrane can freely expand and contract around, which facilitates the connection between the elastic buckle and the clamping ring.

Optionally, the strap is a Velcro strap.

By adopting the above technical solution, the fixing and untying of the strap are relatively convenient.

In summary, the present application includes at least one of the following beneficial technical effects:

1. The present application discloses a standing colonoscope training model, which smoothly stands up a humanoid shell by providing a base with an adaptable shelf groove, so that the colon model fixed in the humanoid shell is in a side-lying state, which better simulates the colon state of a patient in a side-lying state during a colonoscopy, improves the simulation degree of the training model, and optimizes the training effect;

2. By installing an air bag at the anorectal section of the colon model to simulate the contraction force of the human anus and prevent gas leakage in the colon model, the intestinal cavity is sealed during colonoscopy, which better simulates the environment of colonoscopy;

3. By setting the cover as a transparent observation cover, it is convenient to observe the state of the colon model according to training needs. In combination with the peritoneal membrane, the peritoneal membrane can simulate the basic functions of real human peritoneal tissue, which not only reduces the possibility of intestinal bulging during colonoscopy, but also blocks the endoscopist's field of view of the intestine, ensuring the real simulation effect of colonoscopy.
