Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an endoscopic diagnostic and treatment auxiliary device and an endoscope. Background Technology

[0002] During endoscopic diagnosis and treatment, an endoscope needs to be inserted into the lumen of the digestive tract to examine its inner surface. The digestive tract is the longest and largest organ in the human body, with a very large internal surface area. Clinically, it is often necessary to fully expand the lumen using the endoscope's inflation function to allow observation under endoscopic views. However, for some special structures, such as the pharynx of the esophagus, the cardia and pylorus of the stomach, and the anus of the large intestine—areas narrowed by sphincter contraction—as well as the numerous folds of the large intestine, these structures often obstruct the endoscopic's forward field of view, creating blind spots. Conventional digestive endoscopes provide a forward field of view; the field of view angle for upper digestive tract endoscopes is 145°, and for lower digestive tract endoscopes it is 170°. With continuous advancements in optical technology, the physical limits have been reached in balancing image quality and effective observation area. Although the bending and moving of the endoscope tip can compensate for the viewing angle, excessive bending and moving in the confined space of the digestive tract can lead to tearing and damage to the digestive tract.

[0003] Furthermore, endoscopists often need to use their left hand to operate the endoscope's manipulator and their right hand to control the insertion section's movement inside the body. When interventional instruments are required, the endoscopist then uses their right hand to control the instruments' movement, which necessitates temporarily releasing the insertion section and potentially causing the endoscope to shift and lose its target position. Factors such as the structure of the digestive tract, physiological peristalsis, or the endoscope's own elastic recovery can also contribute to this loss of position due to movement. Summary of the Invention

[0022] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings. In this specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of this utility model with reference to the accompanying drawings is intended to explain the overall inventive concept of this utility model and should not be construed as a limitation thereof.

[0023] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of the embodiments disclosed herein. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the figures.

[0024] like Figures 1 to 6 The endoscopic diagnostic and treatment auxiliary device 100 of this utility model embodiment includes a flipping component 110 and a flipping control component 120, wherein the flipping control component 120 can control the flipping component 110 to rotate so as to drive the flipping plate to open or close. When open, it can open up the narrow part or fix the endoscope in a specific target position.

[0025] The flipping assembly 110 of this embodiment includes a base tube 111 and a first set of flipping blades 112. The base tube 111 is generally tubular, and an inner cavity 1111 is formed inside it. The inner cavity 1111 allows the front end of the endoscope body to pass through, so that the diagnostic and therapeutic auxiliary device of this embodiment can be detachably connected to the endoscope body.

[0026] A first guide rail 1112 is provided on the outer periphery of the base tube 111, that is, the first guide rail 1112 is provided around its outer periphery. A first set of flip-plates 112 is provided at one end of the base tube 111, which includes a plurality of first flip-plates 112a.

[0027] The flipping control assembly 120 of this embodiment includes a first control cylinder 121. The first control cylinder 121 has a first inner cavity 1211 and a first guide rail groove 1212. The first inner cavity 1211 allows the flipping assembly 110 to be inserted, enabling the first guide rail groove 1212 to be rotatably connected to the first guide rail 1112, i.e., the flipping control assembly 120 can rotate axially along the outer periphery of the flipping assembly 110. The first control cylinder 121 has a plurality of first arc-shaped openings 1213 evenly arranged, through which the first flipping piece 112a can pass. The first arc-shaped openings 1213 are radially arranged from the inner periphery to the outer periphery of the first control cylinder 121, gradually extending until they penetrate both ends of the first control cylinder 121. When the flipping control assembly 120 is rotated, the arc-shaped openings rotate accordingly. Simultaneously, the arc-shaped openings limit the movement trajectory of the flipping piece through their own structure, thereby causing the flipping piece to open or close.

[0028] In some preferred embodiments, the flipping assembly 110 further includes a second set of flipping blades 113, and correspondingly, the flipping control assembly 120 further includes a second control cylinder 122. The second set of flipping blades 113 is disposed at the other end of the base tube 111, that is, the two sets of flipping blades 112 and 113 are symmetrically arranged at both ends along the radial direction of the base tube 111. The second set of flipping blades 113 includes a plurality of second flipping blades 113a.

[0029] The second control cylinder 122 has a second inner cavity and a second guide rail groove formed on its inner circumference. The second inner cavity allows the flipping assembly 110 to be inserted so that the second guide rail groove and the second guide rail are rotatably connected, meaning that the flipping control assembly 120 can rotate axially along the outer circumference of the flipping assembly 110. The second control cylinder 122 has multiple evenly arranged second arc-shaped openings, through which the second flipping piece 113a can pass. The second arc-shaped openings are arranged radially from the inner circumference of the second control cylinder 122 outwards, gradually extending until they penetrate both ends of the second control cylinder 122. When the flipping control assembly 120 is rotated, the arc-shaped openings rotate accordingly. While rotating, the arc-shaped openings limit the movement trajectory of the flipping piece through their own structure, thereby causing the flipping piece to open or close. The second control cylinder 122 has the same structure as the first control cylinder 121; a structural diagram can be found in the relevant accompanying drawings of the first control cylinder 121.

[0030] It should be noted that each flipping component is independently controlled by a corresponding flipping control component, so as to achieve the effect of opening or closing individually.

[0031] In some preferred embodiments, the first flipper 112a and the second flipper 113a are elliptical in shape, and the elliptical structure can avoid damage to the surface of the cavity.

[0032] In some preferred embodiments, the number and position of the first flip-up flap, the second flip-up flap, and the arc-shaped window correspond one-to-one. For example, the first set of flip-up flaps and the second set of flip-up flaps have at least six flip-up flaps, and correspondingly, there are at least six arc-shaped windows.

[0033] In some preferred embodiments, the flipper is made of an elastic material that is flexible and will bend when subjected to external force and return to its original shape after the external force is removed.

[0034] The endoscope 200 of this utility model embodiment includes an endoscope body 210 and the aforementioned endoscope diagnostic and treatment auxiliary device 110, wherein the front end of the endoscope body can pass through the inner lumen 1111 of the endoscope diagnostic and treatment auxiliary device 110.

[0035] In some preferred embodiments, the endoscope 200 further includes a transparent cap 220, which can be fitted onto the front end of the endoscope body. More preferably, the transparent cap has positioning graduations inside, which are used to help indicate the installation position of the transparent cap. The transparent cap installed on the endoscope provides a minimum field of view from the tip of the endoscope to the end of the cap tube at any position during the endoscope's entry into the digestive tract. Furthermore, due to the presence of the transparent cap, the minimum field of view is not affected even when the flap is closed.

[0036] The endoscopic diagnostic and treatment auxiliary device provided by this utility model can assist the endoscope in opening narrowed parts of the digestive tract and opening the folds of the large intestine for easier access. The device provided by this utility model has a simple structure, is easy to use with existing endoscopes, and can further improve the lesion detection rate.

[0037] The following describes the method of using the endoscopic diagnostic and treatment auxiliary device according to an embodiment of this utility model. It should be noted that this method of use is only an example and does not constitute a limitation on the purpose of the invention.

[0038] In clinical use, the flipping control component of the endoscopic diagnostic and treatment auxiliary device of this embodiment is fitted onto the front end of the endoscope, installed and fixed on the endoscope. The transparent cap is then fitted onto the front end of the endoscope, so that the front end is positioned inside the cavity of the transparent cap, until the front end reaches the positioning mark of the cavity of the transparent cap.

[0039] Depending on the specific needs of the endoscopic procedure, the endoscopist operates the tilting mechanism before inserting the endoscope to open and close it in the desired direction. For example, three opening and closing states can be selected: in the first state, the first tilting flap opens and closes towards the front of the endoscope's tip; in the second state, the second tilting flap opens and closes towards the rear of the endoscope's tip; and in the third state, the first and second tilting flaps simultaneously open and close towards the front and rear of the endoscope's tip, respectively.

[0040] In the first opening and closing state, if it is necessary to examine a narrow part of the digestive tract, such as the pharynx of the esophagus, the cardia and pylorus of the stomach, or the anus of the large intestine, the endoscopist rotates the first control cylinder to open the first flap. Then the endoscope enters the digestive tract. The tip of the forward-opening flap presses against the inner wall of the narrow part and is subjected to the pressure of the narrow part. As the endoscope continues to advance, the flap will be opened further. When the flap opens beyond its limit, it will bend and deform, thereby opening the narrow part and supporting a larger space for the endoscope to explore the inner wall surface of the narrow part. Continue to advance the endoscope until it passes through the narrow part. The flap returns to its original opening position due to its own flexibility.

[0041] In the second opening / closing position, during a lower gastrointestinal tract examination, the numerous folds distributed throughout the large intestine create blind spots in the endoscope's forward field of view. The endoscopist rotates the second control tube to open the second flap. As the endoscope, already inserted into the digestive tract, withdraws from the body, the tip of the rearward-opening flap encounters the folds of the digestive tract and is subjected to pressure from them. As the endoscope continues to withdraw, the flap opens further. When the flap opens beyond its limit, it bends and deforms. The endoscope continues to withdraw until the flap slides out of the fold, thus flattening the fold. When the tip of the endoscope withdraws to the flattened fold, the inner wall surface of the fold can be visualized.

[0042] In the third opening / closing state, when the endoscope reaches the target location in the digestive tract for treatment, factors such as the digestive tract structure, physiological peristalsis, or the endoscope's own elastic recovery necessitate the endoscopist manually holding the endoscope's insertion tube externally to prevent it from shifting and losing its target position. The endoscopist rotates the flipping control component to open the first and second flipping flaps. The tips of both flaps simultaneously press against the digestive tract wall, creating inward resistance that keeps the endoscope stationary at the target position. This eliminates the need for the endoscopist to manually hold the insertion tube externally, freeing their hands to perform other procedures.

[0043] At the end, the endoscopist removes the endoscope along with the auxiliary diagnostic and treatment device of this invention from the body, disconnecting the two.

[0044] Those skilled in the art will understand that the embodiments described above are exemplary and can be improved upon. The structures described in the various embodiments can be freely combined without causing any conflict in structure or principle.
