Description

Technical Field

[0001] The utility model relates to the technical field of endoscopy skill training, in particular to a simulation training device that can be used for intestinal endoscopy. Background Art

[0002] With the advancement of modern medicine, intestinal endoscopy and treatment technologies have become crucial in the diagnosis and treatment of intestinal diseases. For example, colonoscopy allows direct observation of the interior of the colon and rectum, playing an irreplaceable role in detecting polyps, tumors, inflammation, and other lesions. However, intestinal endoscopy is a highly technical medical skill. Furthermore, intestinal endoscopy allows for digital storage and processing of images, facilitating case analysis, consultations, and the long-term preservation of patient examination data. Therefore, intestinal endoscopy is a vital medical device for the diagnosis and treatment of intestinal diseases.

[0003] When using an intestinal endoscope (such as a colonoscopy) to perform an intestinal examination on a patient, the doctor needs to slowly insert the tip of the colonoscope into the patient's anus, passing through the rectum, sigmoid colon, descending colon, transverse colon, ascending colon, and finally reaching the cecum and ileocecal region. When passing through the bends of the sigmoid colon and colon, the doctor needs to rotate and advance and retreat the colonoscope to smoothly navigate these bends, which requires the doctor to have skilled operation skills.

[0004] Improper intestinal endoscopy can lead to a variety of complications, such as intestinal perforation and bleeding, which can not only cause great pain to patients but can even be life-threatening. Therefore, cultivating skilled and high-quality intestinal endoscopy physicians has become an urgent need in the medical field.

[0005] In the traditional intestinal endoscopy training model, early physicians primarily learn and practice on patients. This approach presents several serious problems. First, for patients, accepting procedures from inexperienced physicians means taking on increased risk and potentially suffering unnecessary pain and injury. Second, for novice physicians, the intense psychological pressure of working with real patients in a tense clinical environment makes it difficult to focus on learning and improving their skills. Furthermore, limited opportunities to practice on patients make it difficult to quickly accumulate sufficient experience.

[0006] There is also the use of animal specimens for intestinal endoscopy training. Although this method alleviates the problems of direct operation on patients to a certain extent, the intestinal anatomical structure of animals is different from that of humans, which means that the skills acquired in animal models cannot be fully accurately applied to human patients.

DETAILED DESCRIPTION

[0036] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0037] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0038] Example 1

[0039] like Figure 1-8 、 Figure 13 As shown, in order to provide medical personnel with a more realistic training device, enabling them to repeatedly simulate endoscopic examinations on patients, this embodiment provides a new training device. The training device includes a colonoscope 1, a monitor 11, and a humanoid model 2. The colonoscope 1 is electrically connected to the monitor 11 and can be inserted through the anus of the humanoid model 2 and moved along the intestinal mold within the humanoid model 2. This allows medical personnel to repeatedly practice how to navigate the tortuous intestines with ease and gentleness. The intestinal mold can be made of rubber.

[0040] The colonoscope 1 is a publicly available device that includes an insertion section, an operating section, and a connection section. The insertion section includes a tip, a bend, and a flexible tubing section. The tip is the front end of the colonoscope, typically designed with a smooth, rounded tip to minimize damage to the intestinal mucosa during insertion. The tip is equipped with an illumination device and imaging equipment. The illumination device is typically a cold light source that emits sufficient light intensity to illuminate the interior of the intestine, ensuring a clear field of view. The imaging equipment primarily includes a miniature camera (in electronic colonoscopes) or an optical lens system (in fiber colonoscopes) for capturing images of the intestinal interior. The bend is the key structure that enables the colonoscope to flexibly maneuver within the intestine. It typically consists of multiple flexible joints interconnected by special mechanical structures or control cables. The physician can operate the colonoscope's control knobs externally, pulling or pushing the bend joints via the control cables to bend the colonoscope in various directions within the intestine, such as up, down, left, and right. The flexible tubing encloses various internal structures, such as the lighting and imaging circuits, the air and water injection pipes, and the working channel.

[0041] The operating section has multiple control knobs for manipulating the curvature of the colonoscope. These typically include up and down curvature control knobs and left and right curvature control knobs. It also features buttons or valves for air and water infusion. The operating section also has a biopsy channel entrance for inserting various endoscopic treatment or examination instruments, such as biopsy forceps, snares, and injection needles.

[0042] The connection part has a light source connection interface and an image transmission interface. The light source connection interface is used to connect an external cold light source device, and the image transmission interface is responsible for transmitting the electrical signal obtained by the advanced camera to the external image processing system and monitor.

[0043] In order to be able to present images inside the intestine, the monitor 11 needs to be equipped with an image processing system (including a signal receiving circuit, an amplification and gain adjustment unit, a filtering unit, a color correction and restoration unit, a contrast and brightness adjustment unit, a storage unit (such as a solid-state hard drive), and a transmission unit (such as a cable)). The image processing system is used to receive, process and amplify the electrical signals from the camera at the tip of the colonoscope. It can optimize the image, such as adjusting the contrast, color saturation, etc., to improve the quality and clarity of the image. The monitor 11 is used to display the processed image of the inside of the intestine, and the doctor performs inspections and operations by observing the monitor. Factors such as the size, resolution and display effect of the monitor will affect the doctor's observation and judgment of intestinal lesions.

[0044] To ensure that the humanoid mold can be stably and adjustably positioned next to the monitor 11, a support assembly 4 is provided between the humanoid mold 2 and the monitor 11. The support assembly 4 allows the position of the humanoid mold 2 to be adjusted, facilitating the insertion of the colonoscope 1 into the humanoid mold 2 by trained personnel. Furthermore, when the device is not in use, the humanoid mold 2 can be placed close to the monitor 11, reducing its size and minimizing its impact on the surrounding area.

[0045] Specifically, the support assembly 4 includes a laminating plate 41, a retractable rack 42 and a lifting rack 43. The lifting rack 43 and the laminating plate 41 are respectively arranged at the two ends of the retractable rack 42. The lifting rack 43 is installed on the side wall of the monitor 11. At the same time, the laminating plate 41 is fitted to the back of the human-shaped mold 2 through the action of the strap 413. The length of the retractable rack 42 is adjustable to achieve the position of the laminating plate 41 relative to the lifting rack 43, so that the human-shaped mold 2 can be controlled to move on the horizontal line.

[0046] To achieve the adjustment of the length of the retractable rack 42, the retractable rack 42 includes multiple connecting plates 421. The multiple connecting plates 421 are evenly divided into multiple groups, and the multiple groups of connecting plates 421 are all in two sets. The two sets of connecting plates 421 are distributed vertically, and adjacent two groups of connecting plates 421 in each set are hinged together. At the same time, each group includes two connecting plates 421 that are cross-hinged together. Therefore, under the action of an external force, the adjacent connecting plates 421 can be controlled to retract and extend, realizing the retraction and extension of the entire retractable rack 42.

[0047] To stably connect the two sets of connecting plates 421 to the fitting plate 41, one end of the two sets of connecting plates 421 close to the fitting plate 41 is hinged to the fitting plate 41, and the other end can move relative to the connecting plate 41, facilitating the adjustment of the included angle between the two hinged connecting plates 421 under the action of an external force, and thus the retraction and extension of the retractable rack 42 can be realized.

[0048] To achieve the movable connection between the connecting plate 421 and the fitting plate 41, a driving rod 422 is arranged at the same end of the two sets of connecting plates 421 through a bearing connection. Clamping plates 423 are sleeved at both ends of the driving rod 422. A connecting frame 411 is fixedly arranged on the side wall of the fitting plate 41, and a clamping groove is arranged on the side wall. The structure of the clamping groove is adapted to that of the clamping plate 423. Therefore, the two clamping plates 423 are respectively clamped on the upper and lower sides of the connecting frame 411, realizing the stable and movable connection between the driving rod 422 and the fitting plate 41. To control the movement of the driving rod 422 relative to the fitting plate 41, a threaded column 412 is arranged at the end of the connecting frame 411 through a bearing connection. The threaded column 412 penetrates through the driving rod 422 in a threaded manner. Therefore, when the threaded column 412 is rotated, the movement of the driving rod 422 can be controlled.

[0049] An end plate 44 is arranged on the side of the two sets of connecting plates 421 away from the fitting plate 41, and the end plate 44 is installed on the side of the lifting frame 43. To stably connect the two sets of connecting plates 421 to the end plate 44, one end of the two sets of connecting plates 421 close to the fitting plate 41 is hinged to the end plate 44, and the other end can move relative to the end plate 44, facilitating the adjustment of the included angle between the two hinged connecting plates 421 under the action of an external force, and thus the retraction and extension of the retractable rack 42 can be realized.

[0050] To achieve the movable connection between the connecting plate 421 and the end plate 44, pulleys 424 are hinged at the ends of the two sets of connecting plates 421. A limiting plate 45 is arranged on the side of each pulley 424. The limiting plate 45 is arranged in a U-shaped structure and is connected to the side of the end plate 4 through bolts. Therefore, under the action of the limiting plate 45, the position of the pulley 424 is limited. At the same time, because the size is larger than that of the pulley 424, it does not affect the movement of the pulley 424. Specifically, a convex plate 451 is fixedly arranged on the inner side of the limiting plate 45, and the convex plate 451 extends into the pulley 424.

[0051] Under the premise of realizing that the human-shaped mold 2 can move horizontally, in order to be able to control the lifting and lowering of the human-shaped mold 2, the lifting frame 43 includes a cross plate 435 and two vertical plates 431. The cross plate 435 is connected to the end plate 44, and the vertical plates 431 are connected to the monitor 11. Four connecting plates 437 are fixedly installed on the side of the cross plate 435. The four connecting plates 437 are distributed on both sides of the two vertical plates 431, and the fixed columns are located in the slots 432 of the vertical plates 431. A filling column 438 is fixedly installed between the two connecting plates 437. The filling column 438 is set in the inner cavity 433 of the vertical plate 431. The above-mentioned structural arrangement realizes the stable connection between the vertical plate 431 and the cross plate 435, while not affecting the lifting and lowering of the cross plate 435, thereby realizing the lifting and lowering of the human-shaped mold 2.

[0052] In order to control the lifting and lowering of the human-shaped mold 2, the inner cavity 433 is set along the height direction of the vertical plate 431. An adjusting screw 434 is set in the inner cavity 433 of one of the vertical plates 421. The adjusting screw 434 thread passes through the filling column 438. Therefore, when the adjusting screw 434 is rotated, the cross plate 435 can be controlled to rise or fall along the height direction of the vertical plate 431.

[0053] In order to be able to adjust the orientation of the human-shaped mold 2 as needed, to facilitate the completion of training and the storage of the device, a through hole is provided in the middle of the cross plate 435, and a connecting shaft 442 is vertically provided in the middle of the end plate 44. The connecting shaft 442 is connected to the through hole by a bearing. Under the operation of the trainer, the end plate 44 can rotate around the connecting shaft 442 to control the human-shaped mold 2 to rotate to a horizontal or vertical state.

[0054] To ensure stable placement of the adjusted human-shaped mold 2, first limiting holes 436 are provided at each corner of the cross plate 435, and second limiting holes 441 are provided at both corners of the end plate 44, with the second limiting holes 441 directly opposite one of the limiting holes 436. A pulling plate 46 is provided on the side of the end plate 44 away from the cross plate 435. Limiting rods 462 are provided at both ends of the pulling plate 46, extending through the first limiting holes 436 and the second limiting holes 441. This allows the end plate 44 and the cross plate 435 to remain relatively stationary, ensuring stable placement of the human-shaped mold 2.

[0055] In order to control the limiting rod 462 to stably penetrate the limiting hole and move under the action of external force, a magnet 461 is also embedded in the pulling plate 46. The magnet 461 attracts the end plate 44, which can force the limiting rod 462 to be stable. Of course, the limiting rod 462 can also be forced out of the limiting hole by controlling the movement of the pulling plate 46, thereby releasing the constraints of the end plate 44 and the cross plate 435.

[0056] Example 1

[0057] like Figure 1 、 Figure 9-12 As shown, based on Example 1, in order to facilitate beginners to train the operation of the operating part of the colonoscope 1 and free their hands, an auxiliary component 3 is also provided on the side of the monitor 11. The auxiliary component 3 includes a base 31, a first support arm 32, a second support arm 34 and a third support arm 35. The adjacent ends of the first support arm 32 and the third support arm 35 are respectively hinged at the two ends of the second support arm 34, and the ends away from each other are respectively connected to the base 31 and the pushing mechanism 5. Therefore, the base 31, the first support arm 32, the second support arm 34 and the third support arm 35 form a support arm group with adjustable length, which provides convenience for trainees to adjust the position of the pushing mechanism 5 according to needs so that it is close to the anus of the human-shaped mold 2, forcing the insertion part of the colonoscope 1 to be inserted into the human-shaped mold 2. A servo 33 can also be provided at the hinged setting of the base 31, the first support arm 32, the second support arm 34 and the third support arm 35. The servo 33 is used to control the rotation of the adjacent support arms. The servo 33 has been adapted to the manipulator to achieve adjustment of its various nodes. Therefore, the servo 33 controlling the rotation of each support arm is an existing technology and will not be described in detail here.

[0058] Specifically, the pushing mechanism 5 includes a support plate 51, a motor 52, two rollers 54, and two support plate groups 53. The two support plate groups 53 are vertically arranged on the sides of the support plate 51. The two rollers 54 are hingedly arranged between the two support plate groups 53, and each side wall is provided with a curved groove 541. The colonoscope 1 is arranged through the curved groove 541. The central axis of one of the rollers 54 is connected to the motor 52. Under the action of the motor 52, the roller 54 can be controlled to rotate, thereby pushing the colonoscope 1 slowly into the humanoid mold 2. In actual production, the motor 52 can be configured as a feed motor, a servo motor, or a gearbox (such as a reducer) can be provided at the end of the motor.

[0059] To control the movement of the two rollers 54, the support plate assembly 53 includes a first plate 531 and a second plate 534. A splicing plate 532 and a splicing groove 533 are respectively provided at the ends of the first plate 531 and the second plate 534 that are adjacent to each other. The splicing plate 532 is inserted into the splicing groove 533, enabling the first plate 531 and the second plate 534 to be adjustably connected. At the same time, the first plate 531 and the second plate 534 are respectively aligned with the two rollers 54, thereby enabling adjustment of the two rollers 54. Furthermore, a rotating screw 535 is provided on the second plate 534 via a bearing connection. The rotating screw 535 is threadedly provided through the first plate 531, so that the relative movement of the first plate 531 and the second plate 534 can be controlled by rotating the rotating screw 535.

[0060] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
