Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device processing, and in particular to a small bowel endoscope cannula lifting device. Background Technology

[0002] Enteroscopy is an important technique for the detection and diagnosis of intestinal diseases. During the procedure, both the endoscope and the cannula need to be manipulated simultaneously to allow the endoscope to move within the body. In practice, the cannula often needs to be secured to prevent it from moving during insertion. Currently, external personnel or instruments are required to assist in securing the cannula, such as the device disclosed in application number 202121426965.9, which uses a special support hook connected to the connecting part at the end of the cannula to assist in securing the connection. However, such existing supports occupy operating space and obstruct the line of sight, easily interfering with the enteroscopy procedure. Therefore, the applicant proposes an enteroscopy cannula lifting device to solve the problems existing in the prior art. Utility Model Content

[0003] To address the aforementioned technical problems, this invention provides a small bowel endoscope cannula lifting device, which has a simple structure, is easy to operate, and effectively solves the existing problems.

[0004] To address the aforementioned problems, this utility model provides a small enteroscopy cannula lifting device, including a connecting part and a fixing ring part disposed at one end of the connecting part, wherein the end of the connecting part away from the fixing ring part forms a connecting rope; the lifting device further includes a locking structure disposed at the end of the connecting rope away from the fixing ring part, wherein the locking structure can be fixedly connected to the connecting rope so that the connecting rope forms a wristband part that can wrap around a person's hand.

[0005] Furthermore, the end knot of the connecting rope forms the locking structure.

[0006] Furthermore, the locking structure includes a housing with a mounting cavity and an adjusting wheel rotatably disposed within the mounting cavity. The housing has through holes at both ends of the mounting cavity. The connecting ropes at both ends of the wristband can pass through the through holes and extend to both sides of the adjusting wheel, so that the adjusting wheel can press the connecting ropes against the housing. When the adjusting wheel rotates, the connecting ropes on both sides can move synchronously.

[0007] Furthermore, the side wall of the outer casing at the point where the connecting rope passes through is configured as a rotatable adjusting plate. The adjusting plate can rotate between a first position and a second position, and when the adjusting plate is in the first position, it can be engaged with the outer casing. When the adjusting plate is in the first position, the minimum distance between the adjusting plate and the adjusting wheel is h1, and the adjusting plate and the adjusting wheel press the connecting rope so that the adjusting wheel can be driven to rotate when the end of the connecting rope is pulled away from the fixed ring. When the adjusting plate is in the second position, the minimum distance between the adjusting plate and the adjusting wheel is h2, where h1 is less than h2, so that the connecting rope can slip and move through relative to the adjusting wheel when the end of the connecting rope is pulled away from the fixed ring.

[0008] Furthermore, the side wall of the outer casing at the point where the connecting rope passes through is configured as a rotatable adjusting plate. The adjusting plate can rotate between a first position and a third position, and when the adjusting plate is in the first position and the third position, it can be respectively engaged with the outer casing. When the adjusting plate is in the first position, the minimum distance between the adjusting plate and the adjusting wheel is h1, and the adjusting plate and the adjusting wheel squeeze the connecting rope so that when the end of the connecting rope is pulled away from the fixed ring, the adjusting wheel can be driven to rotate. When the adjusting plate is in the third position, the minimum distance between the adjusting plate and the adjusting wheel is h3, and h1 is greater than h3, so that the adjusting plate and the adjusting wheel squeeze the connecting rope tightly.

[0009] Furthermore, the bottom of the adjustment plate is provided with an arc-shaped protrusion.

[0010] Furthermore, the center of the arc-shaped protrusion is offset on the side of the center of the adjusting wheel facing the end of the connecting rope.

[0011] Furthermore, the connecting rope is configured as a hollow silicone tube.

[0012] Furthermore, the end of the connecting rope away from the wristband is knotted to form the fixing loop.

[0013] Furthermore, the fixing ring includes an arc-shaped rod, one end of which is fixedly connected to the connecting rope, and the other end forms a hook. The fixing ring is formed by passing the connecting rope through the hook.

[0014] The advantages of this utility model are that it has a simple structure, is easy to operate, and effectively solves the existing problems. Attached Figure Description

[0022] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0023] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0024] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0026] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0027] In this utility model, such as Figure 1-5 As shown, a small enteroscopy cannula lifting device is provided, including a connecting part 1 and a fixing ring 2 disposed at one end of the connecting part 1. The end of the connecting part 1 away from the fixing ring 2 forms a connecting rope 4. The lifting device also includes a locking structure disposed at the end of the connecting rope 4 away from the fixing ring 2. The locking structure can be fixedly connected to the connecting rope 4 so that the connecting rope 4 forms a wristband 3 that can wrap around a person's hand.

[0028] When using the cannula lifting device of this utility model, the operator's hand passes through the hand ring part 3 and the fixing ring part 2 is fixed to the upper end of the cannula. By adjusting the position of the locking structure, the operator's hand can lift and limit the cannula through the lifting device. During the insertion of the endoscope, it can prevent the cannula from being moved along with it. Moreover, the operator can also use the wrist to exert force to finely adjust the position of the cannula upward.

[0029] The lifting device of this utility model has the following characteristics when in use: First, the operator of the small enteroscopy cannula can be directly controlled by the lifting device, which is convenient for the operator to control the cannula; Second, compared with the existing support structure, the lifting device has a simple structure, occupies little space, and has less impact on the operating space and line of sight; Third, the end of the connecting rope 4 is fixed to the rope thread of the connecting rope 4 by the locking structure to form a hand ring 3. The size of the hand ring 3 and the length of the connecting part 1 can be adjusted by adjusting the position of the locking structure for convenient use.

[0030] In a preferred embodiment, specifically regarding the structure of this invention, the end of the connecting rope 4 is knotted to form the locking structure. This further simplifies the structure of the entire lifting device, making it easier to manufacture.

[0031] Alternatively, in an alternative embodiment, the locking structure may be configured as shown in the figure, including a housing 5 with a mounting cavity and an adjusting wheel 6 rotatably disposed within the mounting cavity. The housing 5 has through holes at both ends of the mounting cavity. The connecting ropes 4 at both ends of the wristband 3 can pass through the through holes and extend to both sides of the adjusting wheel 6, so that the adjusting wheel 6 can press the connecting ropes 4 against the housing 5, and the connecting ropes 4 on both sides can move synchronously when the adjusting wheel 6 rotates.

[0032] As shown in the figure, after the user's hand passes through the wristband 3, when the length of the connecting part 1 needs to be adjusted, the end of the connecting rope 4 can be pulled. The connecting rope 4 drives the adjusting wheel 6 to rotate, so that the connecting ropes 4 on both sides of the adjusting wheel 6 can move synchronously, thereby keeping the size of the wristband 3 stable. This ensures that the size of the wristband 3 does not change when adjusting the length of the connecting part 1, thus improving the stability of use.

[0033] In one implementation, in the initial state of the lifting device, the connecting rope 4 passes through one side of the adjusting wheel 6. At this time, the position of the outer shell 5 on the connecting rope 4 can be adjusted in advance to fit the size of the user's wrist. Then, the end of the connecting rope 4 passes through the through hole into the mounting cavity, and the size of the wristband 3 is fixed.

[0034] In a preferred embodiment, a further optimization of this utility model is that the side wall of the outer shell 5 at the position where the end of the connecting rope 4 passes through is provided as a rotatable adjusting plate 7. The adjusting plate 7 can rotate between a first position and a second position, and when the adjusting plate 7 is in the first position, it can be engaged with the outer shell 5. When the adjusting plate 7 is in the first position, the minimum distance between the adjusting plate 7 and the adjusting wheel 6 is h1, and the adjusting plate 7 and the adjusting wheel 6 squeeze the connecting rope 4 so that when the end of the connecting rope 4 is pulled away from the fixed ring 2, the adjusting wheel 6 can be driven to rotate. When the adjusting plate 7 is in the second position, the minimum distance between the adjusting plate 7 and the adjusting wheel 6 is h2, where h1 is less than h2, so that when the end of the connecting rope 4 is pulled away from the fixed ring 2, the connecting rope 4 can slip and move through relative to the adjusting wheel 6.

[0035] As shown in the figure, when the size of the wristband 3 needs to be adjusted, the adjusting plate 7 can be rotated to the second position. At this time, the connecting rope 4 between the adjusting plate 7 and the adjusting wheel 6 is in a relatively loose state. Pulling the end of the connecting rope 4 will not cause the adjusting wheel 6 to rotate, thus allowing the size of the wristband 3 to be adjusted. After the size of the wristband 3 is adjusted, the adjusting plate 7 is rotated to the first position. At this time, the adjusting plate 7 can press the connecting rope 4 against the adjusting wheel 6. When the end of the connecting rope 4 is pulled forcefully, the adjusting wheel 6 will rotate synchronously, so that the connecting ropes 4 on both sides of the adjusting wheel 6 can be adjusted and moved synchronously.

[0036] In the illustrated embodiment, regarding the way the adjusting plate 7 is engaged with the outer casing 5 in the first position, more specifically, as shown in the figure, the outer casing 5 has retaining ribs on both sides of the adjusting plate 7, the inner surface of the retaining ribs is provided with retaining holes 10, and the side of the adjusting plate 7 is provided with retaining protrusions 11. When the adjusting plate 7 is in the first position, the retaining protrusions 11 are engaged in the retaining holes 10 to restrict the adjusting plate 7 from rotating outward to the second position at will.

[0037] In a preferred embodiment, a further optimization of the present invention is that, as shown in the figure, the side wall of the outer shell 5 at the position through which the connecting rope 4 passes is provided as a rotatable adjustment plate 7. The adjustment plate 7 can rotate between a first position and a third position, and when the adjustment plate 7 is in the first position and the third position, it can be respectively engaged with the outer shell 5.

[0038] When the adjusting plate 7 is in the first position, the minimum distance between the adjusting plate 7 and the adjusting wheel 6 is h1, and the adjusting plate 7 and the adjusting wheel 6 squeeze the connecting rope 4 so that when the connecting rope 4 is pulled away from one end of the fixed ring 2, the adjusting wheel 6 can be driven to rotate.

[0039] When the adjusting plate 7 is in the third position, the minimum distance between the adjusting plate 7 and the adjusting wheel 6 is h3, and h1 is greater than h3, so that the adjusting plate 7 is squeezed tightly by the adjusting wheel 6 to the connecting rope 4.

[0040] As shown in the figure, when the length of the connecting part 1 needs to be adjusted, the adjusting plate 7 can be rotated to the first position. At this time, the adjusting plate 7 can squeeze the connecting rope 4 with the adjusting wheel 6. When the end of the connecting rope 4 is pulled, the adjusting wheel 6 will rotate synchronously, so that the connecting ropes 4 on both sides of the adjusting wheel 6 can be adjusted and moved synchronously. After adjustment, by rotating the adjusting plate 7 to the third position, the clamping force between the adjusting plate 7 and the adjusting wheel 6 on the connecting rope 4 is greater, increasing the resistance to pulling the connecting rope 4. This can prevent the connecting rope 4 from moving freely in the position of the adjusting wheel 6 when the sleeve is restricted by the lifting device.

[0041] In the illustrated embodiment, regarding the way the adjusting plate 7 is engaged with the outer casing 5 in the first and third positions, more specifically, as shown in the figure, the outer casing 5 has retaining ribs formed on both sides of the adjusting plate 7. The inner surface of the retaining ribs has two vertically spaced retaining holes 10. The side of the adjusting plate 7 has a retaining protrusion 11. When the adjusting plate 7 is in the first position, the retaining protrusion 11 engages in the upper retaining hole 10 to restrict the adjusting plate 7 from rotating freely outward. When the adjusting plate 7 is in the third position, the retaining protrusion 11 engages in the lower retaining hole 10 to restrict the adjusting plate 7 from rotating back to the first position.

[0042] In the illustrated embodiment, a further optimization is that the bottom of the adjusting plate 7 is provided with an arc-shaped protrusion 8. As shown in the figure, by providing the arc-shaped protrusion 8, the connecting rope 4 can be clamped between the arc-shaped protrusion 8 and the adjusting wheel 6, so as to reduce the resistance between the connecting rope 4 and the adjusting plate 7 when the adjusting plate 7 is in the first position and the connecting rope 4 is pulled outward.

[0043] In the illustrated embodiment, a further optimization is that, as shown in the figure, the center of the arc-shaped protrusion 8 is offset to the side of the center of the adjusting wheel 6 facing the end of the connecting rope 4.

[0044] As shown in the figure, by setting it up in this way, when the adjusting plate 7 is in the third position, when the connecting part 1 is under tension, the adjusting wheel 6 is subjected to a counterclockwise rotational force, which can increase the length of the connecting rope 4 squeezed between the adjusting plate 7 and the adjusting wheel 6, thereby further increasing the resistance to the rotation of the adjusting wheel 6 and further preventing the connecting part 1 from being pulled.

[0045] In a preferred embodiment, specifically regarding the structure of this invention, as shown in the figure, the connecting rope 4 is configured as a hollow silicone tube. As shown, this allows the deformability of the hollow tube to facilitate the adjustment of the position of the adjusting plate 7 at the adjusting wheel 6.

[0046] Furthermore, the existing tubing production lines used for medical syringes can be directly converted to produce the connecting rope 4 of this invention, thereby simplifying the production method of this invention.

[0047] In a preferred embodiment, more specifically regarding the structure of this utility model, the end of the connecting rope 4 away from the wristband 3 is knotted to form the fixing ring 2.

[0048] Alternatively, in an optional embodiment, other forms can be used for the structure of the fixing ring 2, such as the fixing ring 2 including an arc-shaped rod 9, one end of which is fixedly connected to the connecting rope 4, and the other end forming a hook 901, and the fixing ring 2 is formed by passing the connecting rope 4 through the hook 901.

[0049] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0050] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
