Description

Technical Field

[0001] The utility model relates to the technical field of medical teaching, and in particular to a modular colonoscopy training system. Background Art

[0002] At present, digestive endoscopy has been increasingly promoted, and digestive endoscopy screening has been accepted by more and more people. However, the number of physicians engaged in digestive endoscopy diagnosis and treatment is far from enough. As an operation technology, digestive endoscopy technology has a relatively long learning curve and certain operation risks. The traditional hands-on teaching and animal or experiential learning process is long and is not conducive to homogeneous teaching. This technology is designed to give grassroots medical workers more opportunities for endoscopic training, so as to achieve the goal of independent endoscopy operation in a shorter time.

[0003] At present, there are two types of endoscope in vitro simulation devices: one is a complete physical simulation, and the other is a virtual one. Physical simulation cannot fully reflect the characteristics of the actual intestine and cannot cover many practical problems. Virtual simulation is more expensive and has a poor feel.

[0004] The patent with publication number CN211506906U discloses a colon simulation training device, including a box body, a colon model, an anal canal model, a test electrode and a traction and fixation assembly; wherein the colon model is suspended in the box body via the traction and fixation assembly, and the colon model is used to accommodate the colon of the test specimen; the first end of the anal canal model passes into the box body and corresponds to the first end of the colon model, and the second end of the anal canal model passes out of the box body, and the anal canal model is used to accommodate and fix the anal canal of the test specimen; the test electrode is arranged at the first end of the colon model. The colon model is combined with software to simulate colon peristalsis and adjacent arterial pulsation, and can simultaneously simulate the relatively closed abdominal cavity environment during full-thickness resection and perforation, which is very close to clinical practice.

[0005] However, the colon simulation training device is relatively comprehensive and can only perform complete endoscope insertion exercises, but cannot provide targeted training for endoscopic examination techniques. Utility Model Content

[0006] In view of the above problems, the technical ideas adopted by the utility model to solve the technical problems are:

[0007] The endoscopic examination technology is broken down to create training models for knob exercises, cornering exercises, pull-tab exercises, and simulation exercises.

[0008] The specific plan is as follows:

[0009] A colonoscopy modular training system, wherein a colonoscopy training cabinet sequentially accommodates a knob training model, a cornering training model, a pull tab training model and a simulation training model.

[0010] In order to realize the above scheme, a further preferred scheme is that the knob practice model includes a first dark box, a rotating tube, a number disk and a bearing; the rotating tube horizontally passes through the middle of the first dark box; the bearing is connected to one end of the rotating tube; the rotating tube passes through the number disk, and the number disk is evenly arranged on the outside of the rotating tube.

[0011] Another preferred embodiment is that the cornering practice model includes a second dark box, a fixed tube and petals; the fixed tube horizontally penetrates the middle of the second dark box; the petals are evenly arranged on the inner wall of the fixed tube, and the petals are convex crescent-shaped.

[0012] Through the above scheme, another preferred scheme is that the pull-tab training model includes a third dark box, a simulated intestinal loop, a cable tie and an elastic rope; the simulated intestinal loop is placed inside the third dark box; the cable tie is tied at the node of the simulated intestinal loop; one end of the elastic rope is connected to the cable tie, and the other end is connected to the inner wall of the third dark box.

[0013] Furthermore, the mimetic intestinal loops are divided into "α"-shaped mimetic intestinal loops and reverse "α"-shaped mimetic intestinal loops.

[0014] Another preferred embodiment is that the simulation practice model includes a box, a simulated intestine, a cable tie and an arc frame; the simulated intestine is placed inside the box; the cable tie is tied at the node of the simulated intestine; one end of the arc frame is connected to the cable tie, and the other end is connected to the bottom side of the inner wall of the dark box.

[0015] By adopting the above technical solution, the utility model has the following technical effects:

[0016] The knob training model can practice the ability to adjust the size of the knob and the ability to stabilize it; the cornering training model can practice the ability to find a cavity and insert the endoscope; the loop pulling training model can practice the ability to untie the loop of the intestine; the simulation training model simulates the real intestine to achieve complete endoscope insertion training; the utility model of the modular colonoscopy training system decomposes the endoscopic examination technology and can carry out targeted training, so that trainees can have an intuitive understanding of the technical points of endoscopic operation, and at the same time visualize the endoscopic operation process, which is easy to correct errors for trainees, thereby ultimately shortening the learning curve of endoscopic technology, and the cost is low, easy to understand, and suitable for promotion in grassroots hospitals.

[0052] Application Cases

[0053] Colon cancer is a common digestive tract malignancy in my country, and its incidence rate is increasing year by year. my country's tumor control strategy has shifted from treatment to prevention and early diagnosis and treatment. With the improvement of people's health awareness, the development of endoscopic technology and the improvement of the level of endoscopists, most patients with early colon cancer and colon polyps are currently treated by colonoscopic submucosal dissection (ESD) or mucosal resection (EMR). Since colonoscopy is a minimally invasive operation, it causes little damage to patients, has low costs and good prognosis, so it has great application prospects.

[0054] However, ESD has serious complications such as bleeding and perforation, which places high demands on endoscopists. Therefore, endoscopists need to undergo long-term, repeated, and extensive training to master this technique and avoid complications. However, in current clinical practice, beginners have few opportunities to practice.

[0055] Therefore, the modular colonoscopy training system of the present invention decomposes the endoscopic examination technology and produces training models for knob practice, bending practice, pull-tab practice, and simulation practice respectively; the knob practice model is used to practice the ability to adjust the size of the knob and the stability ability, the bending practice model is used to practice the ability to find the cavity and insert the endoscope, the pull-tab practice model is used to practice the ability to untie the loop of the intestine, and the simulation practice model simulates the real intestine to achieve complete endoscope insertion practice.

[0056] The modular colonoscopy training system of the utility model can carry out targeted training, allowing trainees to have an intuitive understanding of the technical points of endoscopic operation. At the same time, the endoscopic operation process can be visualized, making it easy to correct errors for trainees, thereby ultimately shortening the learning curve of endoscopic technology. The system is low-cost, easy to understand, and suitable for promotion in primary hospitals.

[0057] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
