Description

Technical Field

[0001] This utility model relates to the field of medical education and simulation training technology, and in particular to a training model for endoscopes. Background Technology

[0002] With the widespread use of gastroscopy and colonoscopy in gastroenterology and the continuous development of medical technology, doctors are required to constantly improve their endoscopic skills. However, at present, medical students and junior doctors mostly accumulate operational experience through real cases, which is not only time-consuming and inefficient, but also inevitably poses safety risks to patients.

[0003] Most existing endoscopic simulators focus on training diagnostic or treatment skills, such as polyp removal and biopsy, but no product focuses on specialized training in "endoscopic control" skills, especially repetitive training modules for basic abilities such as lens advancement, steering, field of view adjustment, and image stabilization. Furthermore, existing systems often lack quantifiable assessment and feedback mechanisms, making it difficult to achieve individualized teaching and standardized training pathways. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a unique endoscope control training model, which provides users with an effective training device. By simulating the esophagus and several endoscope holes, it simulates the real human endoscope passage. The endoscope control practice covers key skills such as inserting the endoscope, withdrawing the endoscope, turning, lifting, and field of view adjustment.

[0005] To solve this technical problem, the technical solution adopted by this utility model is as follows:

[0006] An endoscope control training model includes a base, several endoscope ports, and a simulated esophagus;

[0007] Several upright fixing rods are arranged and fixedly installed on the base. A pair of roller shafts arranged vertically and parallel to each other are fixedly installed on the fixing rods. U-shaped rollers are fitted on the roller shafts and can rotate freely and are axially limited. The U-shaped grooves between the two U-shaped rollers form the lens hole.

[0008] At least one of the positional data of the two adjacent holes in the horizontal longitudinal direction, horizontal transverse direction, and height changes, thereby forming a simulated gastrointestinal passage through which the user operates the endoscope in sequence.

[0009] A tubular simulated esophagus is provided at the front end of the first endoscopic hole. The simulated esophagus is fixedly connected to the base and is coaxial with the first endoscopic hole.

[0010] Furthermore, the U-shaped roller is mounted on the roller shaft via a bearing.

[0011] Furthermore, the U-shaped roller is covered with a silicone layer.

[0012] Furthermore, the central axis angle of the lens hole is variable, the fixing rod is horizontally rotatable and fixedly connected to the base, and a pair of roller shafts are vertically adjustable and fixedly mounted on the fixing rod.

[0013] Furthermore, a wire harness fixing clip and a light guide plug fixing bracket are also fixedly installed on the base.

[0014] Furthermore, a box-shaped cover is provided on the base. The lower end of the cover is open and forms a detachable fixed connection with the edge of the base. An inlet hole is provided on the front side of the cover. The inlet hole is coaxially matched with the simulated esophagus. The cover covers all the inlet holes. When the cover is closed, an opaque closed space is formed inside.

[0015] Furthermore, the diameter of the lens aperture is 16 to 25 mm.

[0016] Furthermore, the lens aperture is an elliptical aperture.

[0017] Furthermore, a handle is provided on the top of the cover.

[0018] Furthermore, seven endoscope ports are provided. The center positions and central axis angles of the endoscope ports from the first to the seventh are as follows: First, we define the direction in which the endoscope moves through the simulated esophagus towards the endoscope port as the forward direction. The left and right directions are also defined based on the forward direction:

[0019] The center position of the first endoscopic hole is 21 mm forward from the center of the simulated esophagus outlet, and the central axis angle of the first endoscopic hole is horizontal and longitudinal; the central axis of the simulated esophagus is set horizontally and longitudinally and is coaxial with the first endoscopic hole.

[0020] The center position of the second lens hole is 147mm forward from the center of the first lens hole in the horizontal longitudinal direction, and the height of the distance from the center of the first lens hole is 63mm. The center axis angle of the second lens hole is in the horizontal longitudinal direction.

[0021] The center of the third lens hole is 93mm forward from the center of the second lens hole in the horizontal longitudinal direction, and the height from the center of the first lens hole is 47mm. The central axis angle of the third lens hole is in the horizontal longitudinal direction.

[0022] The center position of the fourth lens hole is 108mm forward and 17mm to the right from the center of the third lens hole. The height of the center of the fourth lens hole from the center of the first lens hole is 24mm. The center axis angle of the fourth lens hole is 45° clockwise from the horizontal.

[0023] The center position of the fifth lens hole is 57mm forward and 69mm to the right from the center of the fourth lens hole. The height of the center of the fifth lens hole from the center of the first lens hole is 24mm. The center axis angle of the fifth lens hole is 15° clockwise from the horizontal.

[0024] The center position of the sixth lens hole is 101mm forward and 35mm to the right from the center of the fifth lens hole. The height of the center of the sixth lens hole from the center of the first lens hole is 63mm. The center axis angle of the sixth lens hole is horizontal.

[0025] The center of the seventh lens hole is located 100mm forward and 24mm to the left of the center of the sixth lens hole. The height of the center of the seventh lens hole from the center of the first lens hole is 48mm. The axis angle of the center of the seventh lens hole is 15° counterclockwise.

[0026] This utility model provides users with an effective training device for endoscope control. Through a uniquely designed simulated esophagus and an endoscope movement path composed of several perforations, it simulates the real human endoscope passageway. Endoscope control practice covers key skills such as endoscope insertion, withdrawal, turning, lifting, and field of view control. Multiple training tasks can be set, including target recognition, field of view tracking, and path planning. Furthermore, different training objectives and difficulties can be achieved by setting the number of perforations, their three-dimensional positions, and the angle of their central axis, continuously improving the trainee's endoscope control skills. This training model can realize a realistic, precise, and repeatable endoscope control training system for gastroscopy and colonoscopy, which is of great significance for teaching, examination, and technical standardization.

[0027] To better enable advanced camera control training, this training model also features a box-shaped cover to allow for either open or closed training.

[0028] Open-style training allows for direct observation of the endoscope's movement. By practicing controlling the endoscope and passing through the endoscope hole in sequence, beginners can observe the endoscope's real-time posture in the channel, facilitating adjustments and the establishment of reasonable endoscope manipulation techniques.

[0029] Closed training can more realistically simulate actual camera movement scenarios. Since the camera movement scene cannot be directly observed and the camera passage is dark, the difficulty of camera control is obviously greatly increased, making it suitable for advanced trainees.

[0030] This training model is suitable for tiered training needs ranging from beginners to advanced physicians. Attached Figure Description

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0045] Figure 1 , Figure 2 , Figure 3 An endoscope control training model is shown, including a base 1, several endoscope ports 2, and a simulated esophagus 3. The base 1 is made of acrylic sheet with a thickness of 1.5 cm.

[0046] Seven upright fixing rods 4 are arranged and fixedly mounted on the base 1 in sequence. The top of each fixing rod 4 is numbered 1-7. A pair of vertically parallel roller shafts 5 are fixedly mounted on each fixing rod 4. U-shaped rollers 6 are rotatably fitted onto each roller shaft 5 and axially limited. The U-shaped rollers 6 are mounted on the roller shafts 5 via bearings to increase their smoothness. The U-shaped grooves between the vertically arranged U-shaped rollers 6 form the lens hole 2. The lens hole 2 is generally 16 to 25 mm in diameter and is a near-elliptical hole.

[0047] To facilitate the application of lubricant to the roller 6 and to protect the endoscope lens and simulate the effect, the U-shaped roller 6 is preferably covered with a silicone layer.

[0048] The structure on which the roller shafts 5 are fixedly mounted on the fixing rod 4 consists of an outer plate 7 and an inner plate 8, which are respectively fixedly connected to the outer and inner ends of the two roller shafts 5 positioned above and below, thus forming a structurally stable frame. The inner plate 8 is fixedly connected to the fixing rod 4. Alternatively, other existing fixing structures can be used to fix the upper and lower sets of roller shafts 5 to the fixing rod 4, such as directly fixing the roller shafts 5 to the fixing rod 4 by insertion and screws.

[0049] At least one of the positional data of two adjacent endoscopic holes 2 changes in the horizontal longitudinal direction, horizontal transverse direction, and height. The central axis angle of the endoscopic hole can also be a variable, so that the sequentially arranged endoscopic holes 2 form a simulated gastrointestinal channel for the user to operate the endoscope through in sequence.

[0050] A tubular simulated esophagus 3 is provided at the front end of the first endoscope port 2. The simulated esophagus 3 is fixedly connected to the base 1 via esophageal supports 13 at both ends. The simulated esophagus 3 is coaxial with the first endoscope port 2. The simulated esophagus 3 is made of orange-yellow polyurethane foam and provides support for the endoscope.

[0051] An endoscope movement path can be formed by simulating the esophagus 3 and seven endoscope holes 2. In order to more flexibly adjust the height position of the specific endoscope holes 2 and thus flexibly adjust the training path to match specific training goals, we can adopt a more flexible fixing structure: that is, the fixing rod 4 can be horizontally rotated and fixedly connected to the base 1, so that the central axis angle of the endoscope hole 2 can be adjusted more easily. Specifically, the fixing rod 4 is inserted into the hole groove of the base 1 and then fixed by radial fixing stop screws. A pair of roller shafts 5 can be adjusted up and down and fixedly set on the fixing rod 4. Specifically, the fixing rod 4 and the inner plate 8 can be fixedly connected by screws and nuts. At least one of the fixing rod 4 and the inner plate 8 is provided with a vertically extending oval hole, so that the roller shafts 5 can be adjusted up and down appropriately. After adjusting the accurate position, tightening the screws and nuts can fix the roller shafts 5 and the fixing rod 4.

[0052] To facilitate operation and equipment management, a wire harness fixing clip 9 and a light guide plug / conduit plug fixing bracket 10 are also fixedly installed on the base 1. The wire harness fixing clip 9 is used to fix the light guide cable (including the light guide fiber and the wire) to prevent the cable from getting tangled, bent, or damaged during training when it is not connected to the endoscope host. This ensures the safety of training.

[0053] The light guide plug holder 10 is used to connect and fix the light guide plug (such as a light source or camera connection plug) to prevent it from falling and being damaged due to external force during training when it is not connected to the endoscope host. This ensures the safety of open training. The light guide plug holder 10 includes two plug brackets 101, one at the front and one at the back. The upper end of each plug bracket 101 is a clamp for holding the light guide plug. The lower end of each plug bracket 101 is fixed to the base 1 through a guide groove key structure to form an adjustable spacing fixing structure. That is, the base 1 is provided with a dovetail groove guide groove. Each plug bracket 101 is fixedly connected to a guide slider 102 at its lower end. The lower end of the guide slider is provided with a dovetail key that matches the dovetail groove, so that the two brackets can adjust the spacing along the direction of the dovetail groove to accommodate various types of light guide plugs. When the plug bracket 101 is moved to the appropriate position, it is fixed by fastening screws.

[0054] For advanced operational training, we need to create a more realistic operational environment, namely closed training (a darkroom environment). In this case, such as... Figure 4As shown, a box-shaped cover 11 is also provided on the base 1. The lower end of the cover 11 is open and is detachably fixed to the edge of the base 1 through four sets of buckle structures 15 (of course, screws, pin holes or other detachable fixing structures can also be used). An inlet hole 111 is provided on the front side of the cover 11. The inlet hole 111 is coaxially matched with the simulated esophagus 3. The cover covers all the inlet holes 2. When the cover 11 is closed, an opaque closed space is formed inside. The trainee can only judge the operation through the image on the display, forming an operating environment consistent with the actual operation.

[0055] The top of the cover 11 can be provided with a handle 14, so that when the cover 11 is closed, we can conveniently and safely extract, store and transport the entire endoscope control training model.

[0056] Through extensive experimentation, testing, and research, we have determined the optimal positions and angles for the lens apertures, providing trainees with the most suitable training difficulty. This covers key skills such as lens insertion, lens withdrawal, turning, lifting, and field of view control, and allows for the setting of various training tasks, including target recognition, field of view tracking, and path planning.

[0057] The center position and central axis angle parameters of the endoscope 2 for the first to seventh endoscopes are as follows: First, we define the direction in which the endoscope moves through the simulated esophagus 3 toward the endoscope 2 as the forward direction, and the left and right directions are also defined based on the forward direction:

[0058] The center position of the first viewing hole 2 is 21mm horizontally forward from the center of the outlet of the simulated esophagus 3, and is a distance from the upper plane of the base 1. Figure 3 The height of the reference position A in the figure is 47mm, and the central axis angle of the first lens hole 2 is horizontal and longitudinal; the central axis of the simulated esophagus 3 is also 47mm above the upper plane of the base, and the simulated esophagus 3 is coaxial with the first lens hole 2.

[0059] The center position of the second lens hole 2 is 147mm forward from the center of the first lens hole 2 in the horizontal longitudinal direction, and the height from the upper plane of the base 1 is 110mm. The center axis angle of the second lens hole 2 is in the horizontal longitudinal direction.

[0060] The center of the third lens hole 2 is 93mm forward from the center of the second lens hole 2 in a horizontal longitudinal direction, and the height from the upper plane of the base 1 is 94mm. The central axis angle of the third lens hole 2 is in the horizontal longitudinal direction.

[0061] The center position of the fourth lens hole 2 is 108mm forward and 17mm to the right from the center of the third lens hole 2. The height of the center of the fourth lens hole 2 from the upper plane of the base is 71mm. The center axis angle of the fourth lens hole 2 is 45° clockwise from the horizontal.

[0062] The center position of the fifth lens hole 2 is 57mm forward and 69mm to the right from the center of the fourth lens hole 2. The height of the center of the fifth lens hole 2 from the upper plane of the base 1 is 71mm. The center axis angle of the fifth lens hole 2 is 15° clockwise from the horizontal.

[0063] The center position of the sixth lens hole 2 is 101mm forward and 35mm to the right from the center of the fifth lens hole 2. The height of the center of the sixth lens hole 2 from the upper plane of the base 1 is 110mm. The center axis angle of the sixth lens hole 2 is horizontal.

[0064] The center position of the seventh lens hole 2 is 100mm forward and 24mm to the left from the center of the sixth lens hole 2. The height of the center of the seventh lens hole 2 from the upper plane of the base 1 is 95mm. The center axis angle of the seventh lens hole 2 is 15° counterclockwise from the horizontal.

[0065] The endoscope control training model of this patent simulates the real anatomical path of the human gastrointestinal tract. Combined with image recognition and data acquisition technology, it tracks, records and evaluates key indicators in the control process to achieve standardized and structured control training.

[0066] When using it, the steps are as follows:

[0067] 1. Open the top cover 11, install the fixing rods in sequence according to the numbers on the fixing rods 4, and tighten them with the stop screws;

[0068] 2. Place the endoscope light guide plug on the light guide plug holder 10 and lock it in place. Then, lock the light guide cable through the wire harness fixing buckle 9 in sequence.

[0069] 3. With the endoscope in the open position, operate the endoscope lens to advance and turn, passing through the endoscope hole 2 in sequence for training and evaluation.

[0070] 4. After completing the endoscope operation training in the open state, disconnect the light guide plug and light guide cable from the base, connect the main unit, close the top cover 11, and operate the endoscope through the endoscope hole 2 in sequence under the monitor's view to conduct training and evaluation.

[0071] We studied and obtained the optimal three-dimensional positional relationship of each of the above-mentioned lens holes. In the description, we use the upper plane of the base 1 as the reference height. Obviously, this reference height can be changed at will while keeping the three-dimensional relationship of the seven lens holes 2 unchanged. Therefore, in terms of height parameters, the height relationship between the seven lens holes 2 is more important.

[0072] In addition, in order to obtain different training effects and through different training methods and programs, we can also set other numbers of lens holes 2 or other different positions of lens holes 2 and the angle of the central axis of lens holes 2.

[0073] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
