Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a precision auxiliary device for endoscopic catheter placement. Background Technology

[0002] In clinical practice, catheters are often inserted into the body to achieve therapeutic goals, such as through the nasal cavity or rectum, to ensure the catheter is positioned in a specific location for subsequent clinical treatment or care. Current catheter insertion methods typically involve clamping the catheter with forceps, but the catheter becomes slippery after insertion, making further insertion more difficult. Furthermore, the sharp forceps can cause various types of catheter damage during the clamping process.

[0003] Patent No. ZL201220017456.5, entitled "An Improved Nasojejunal Feeding Tube", features a traction rope at the tip of the catheter to facilitate insertion. However, over time, this single traction rope has failed to meet the diverse clinical needs of today.

[0004] Therefore, to solve the above-mentioned technical problems, a new technical solution is needed. In particular, a precise auxiliary device for endoscopic catheter placement is required. Utility Model Content

[0005] This invention addresses the technical problem of the limited availability of traction ropes in existing endoscopic catheter placement devices by providing a precise auxiliary device for endoscopic catheter placement.

[0006] To achieve the above objectives, the following technical solution is provided: a precise endoscopic catheter placement auxiliary device, comprising a traction rope, a rope sleeve at the front end of the traction rope, and a receiving cavity inside the rope sleeve; a sleeve below the rope sleeve, the traction rope below the rope sleeve passing through the cavity inside the sleeve; and a knot below the traction rope, the knot being located behind the sleeve or inside the cavity of the sleeve and extending downward.

[0007] Preferably, multiple knots are provided and arranged sequentially, and the length of each knot is 2-3 cm.

[0008] Preferably, the diameter of the knot is greater than or equal to the diameter of the cavity and smaller than the endoscopic forceps channel.

[0009] Preferably, the endoscopic cannula includes a body, on which a guide head is sequentially provided; the guide head is provided with multiple joints, and the lanyard is disposed at the first joint of the guide head.

[0010] Preferably, the endoscopic catheter body is further provided with a first balloon and a second balloon in sequence, and the lanyard is also provided behind the second balloon.

[0011] Beneficial effects:

[0012] This utility model discloses a precision assist device for endoscopic cannulation. Its front end can be fitted onto an endoscopic cannula. The position of the cannula can be adjusted according to the diameter of different endoscopic cannulas, thereby adjusting the size of the cavity within the loop. This allows the loop at the front of the traction rope to accommodate endoscopic cannulas of different diameters. Simultaneously, a knot is provided at the bottom of the traction rope, extending outward from inside the cannula. The diameter of the knot is greater than or equal to the diameter of the cannula cavity, ensuring the cannula fits tightly around the knot. This prevents the cannula from slipping after adjustment, ensuring a tight fit of the loop onto the endoscopic cannula. The knot's diameter is smaller than the endoscopic forceps channel, allowing it to be pulled into the channel without obstructing the endoscopic view. The knot serves two purposes: securing the cannula's position and increasing the friction between the traction rope and the biopsy forceps. By clamping the knot at the end of the traction rope with the biopsy forceps, the insertion of the endoscopic cannula is controlled, facilitating precise placement of the endoscopic cannula into the target location.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. The specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0019] In the description of this utility model, it should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to or indirectly connected to the other element.

[0020] In the description of this utility model, it should be noted that the terms "center," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.

[0021] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] In this utility model, "endoscopic catheterization" is a term defined in this article, which means various catheters that are inserted into the human body in conjunction with an endoscope, such as intestinal obstruction catheters and feeding tubes.

[0023] like Figures 1 to 3 As shown, a precision assist device for endoscopic catheter placement includes a traction rope 1 with a loop at its front end and a receiving cavity 2 inside the loop. A sleeve 3 is located below the loop, and the traction rope below the loop passes through the cavity 31 inside the sleeve 3. The loop is formed by connecting the traction ropes, and both ends of the traction rope pass through the cavity inside the sleeve. A knot 4 is located below the traction rope 1. In this embodiment, multiple knots 4 are arranged sequentially, and the total length of the multiple knots 4 is 2-3 cm. The knots 4 are located within the cavity 31 of the sleeve 3 and extend downwards.

[0024] The diameter of the knot 4 is greater than or equal to the diameter of the cavity 31. This ensures that the cannula is tightly fitted around the knot, thus fixing the position of the cannula during use. The knot diameter is smaller than the endoscope forceps channel, allowing it to be pulled into the channel without affecting the endoscope's field of vision. The cannula controls the diameter of the cavity within the cannula. Once the cannula's position is fixed, the diameter of the cavity is also fixed, allowing the adjusted traction rope to be tightly fitted around the endoscope cannula. Furthermore, the knot increases the contact area between the traction rope and the biopsy forceps, further increasing the coefficient of friction. During use, the biopsy forceps can firmly clamp the traction rope, preventing the rope itself from being unable to be held.

[0025] The traction rope and rope sling are made of existing materials, and the specific material is not limited. In this embodiment, the traction rope can be made of cotton or nylon, and the rope sling can be made of plastic. The knot in this invention can be a dead knot on the traction rope or other alternative structures with a diameter larger than the traction rope itself that connect the two ends of the traction rope together. In this embodiment, a dead knot or a surgical knot is preferred.

[0026] The endoscopic catheters used in this invention include various types, such as intestinal obstruction catheters or feeding tubes. For example... Figure 3 As shown, in one embodiment of this utility model, an endoscopic cannula 5 is also included. The endoscopic cannula 5 includes a body, on which a guide head 51 is sequentially provided. The guide head 51 has multiple joints, and the rope loop is disposed at the first joint of the guide head 51. The guide head has multiple interconnected joints, and the joints are concave. The rope loop is disposed at the first joint of the guide head. The body of the endoscopic cannula 5 also has a first balloon 52 and a second balloon 53 sequentially provided. The rope loop is also disposed behind the second balloon 53. When the traction rope is held and transported forward using biopsy forceps, since the diameter of the second balloon is larger than that of the body and the diameter of the rope loop, even if the traction rope slides on the body of the endoscopic cannula during forward transport, it will be blocked by the second balloon. This facilitates control of the position ratio of the traction rope on the endoscopic cannula, thereby facilitating control of the movement of the entire endoscopic cannula.

[0027] This invention provides a precise endoscopic cannulation aid device. The diameter of the lanyard cavity is controlled by the forward and backward movement of the cannula, allowing the lanyard to adapt to endoscopic cannulas of different diameters. After adjusting the cannula's position, a knot in the lanyard prevents it from moving. The knot further increases the coefficient of friction between the biopsy forceps and the traction rope. This invention allows for precise insertion of the endoscopic cannula by using the biopsy forceps to hold the traction rope and clamping it to the target location.

[0028] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
