Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an endoscopic polyp collector. Background Technology

[0002] In endoscopic surgery, smaller polyps can be removed by suctioning them out of the body through the suction channel of the endoscope using negative pressure. A collector is attached to the suction port of the endoscope to collect the polyps.

[0003] Currently, there are two types of collectors: straight-through and cup-type. The inventors discovered through research that the straight-through collector is a single-chamber type, and other useless debris is filtered into the collection chamber and mixed with polyps, making it difficult to distinguish polyps; while the cup-type collector's suction airflow turns 360 degrees inside the collector, causing some water to remain at the bottom of the collector and not be completely sucked out, resulting in a loss of some suction pressure.

[0004] Based on the above background, the inventors designed an endoscopic polyp collector that can solve at least one of the problems, and hereby file this application. Summary of the Invention

[0005] The purpose of this application is to provide an endoscopic polyp collector to solve the problems of existing polyp collectors, which either collect polyps mixed with other debris, making the polyps difficult to distinguish, or suffer from large suction pressure loss, or leave some wastewater at the bottom.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0007] This application provides an endoscopic polyp collector, including a collector body, the collector body including a cup body having a main cavity, and a cup lid body that can be covered on the cup body and rotated around the cup body.

[0008] The cup body is provided with an inlet connector that communicates with the main cavity of the cup body and is used to dock with the endoscope suction port, and an outlet connector that communicates with the main cavity of the cup body and is used to dock with the suction tube.

[0009] It also includes a filter structure that is fixed to the bottom of the cup lid body and is eccentrically positioned;

[0010] The collector body has two states: one where the inlet connector is directly connected to the outlet connector, and another where the inlet connector is connected to the outlet connector via a filter structure.

[0011] Optionally, the filter structure includes a filter body fixed vertically to the bottom of the cup lid body along the axial direction of the cup lid body;

[0012] With the lid body fastened onto the cup body, both ends of the filter body are positioned close to the inner circumferential wall of the cup body, and the bottom of the filter body is positioned close to the bottom of the cup body.

[0013] Optionally, the included angle between the lines connecting the two end faces of the filter body and the central axis of the cup lid body is less than 180°.

[0014] Optionally, the filter body can be any one of curved, bent, or straight shapes.

[0015] Optionally, the filter structure further includes a base plate fixed to the bottom of the filter body and arranged parallel to the cup lid body;

[0016] The bottom plate, the filter body, and the inner peripheral wall of the cup body can form a collection cavity located within the main cavity of the cup body;

[0017] The number of collection chambers can be one or more;

[0018] The side of the base plate near the main body of the cup is an arc-shaped sidewall that fits the inner circumference of the main body of the cup.

[0019] Optionally, the inner peripheral wall of the cup body is provided with a first limiting rib and a second limiting rib for confirming whether the collector body is in state one or state two.

[0020] The first limiting rib and the second limiting rib are located on both sides of the line connecting the inlet joint and the outlet joint, respectively.

[0021] The filter structure is located on the side of the first and second limiting ribs near the inlet connector.

[0022] Optionally, the filter structure is an axisymmetric structure; when the filter structure abuts against the first limiting rib, the central axis of the inlet connector is directly opposite the central axis of symmetry of the filter structure.

[0023] Optionally, the inlet connector and the outlet connector are coaxially arranged and located on opposite sides of the cup body.

[0024] Optionally, the inlet connector is also provided with a connecting tube for connecting to the endoscope suction port.

[0025] Optionally, the sides of the cup lid body are provided with an anti-slip structure.

[0026] The beneficial effects of this utility model are:

[0027] The concept for solving the technical problem in this application is as follows: by setting a cup body and a cup lid body that can rotate on the cup body, and at the same time setting a filter structure at the bottom of the cup lid body, the operator can change the position of the filter structure in the main cavity of the cup body by rotating the cup lid body. This allows the collector body to be in state one where the inlet connector is directly connected to the outlet connector, or in state two where the inlet connector is connected to the outlet connector through the filter structure. This allows the operator to switch the state of the collector as needed, achieving either collecting the filtered polyps in state two, or avoiding the suction pressure loss caused by the suction airflow passing through the filter structure in state one, and removing other useless residue, thereby effectively solving the problem of the prior art.

[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] like Figures 1 to 5 As shown, this embodiment provides an endoscopic polyp collector, including a collector body, the collector body including a cup body 1 having a cup body main cavity 101, and a cup lid body 2 that can be covered on the cup body 1 and rotated around the cup body 1.

[0039] The cup body 1 is provided with an inlet connector 11 that communicates with the main cavity 101 of the cup body and is used to connect with the endoscope suction port, and an outlet connector 12 that communicates with the main cavity 101 of the cup body and is used to connect with the suction tube.

[0040] It also includes a filter structure 4 that is fixed to the bottom of the cup lid body 2 and is eccentrically positioned;

[0041] The collector body has a state one in which the inlet connector 11 is directly connected to the outlet connector 12, and a state two in which the inlet connector 11 is connected to the outlet connector 12 via the filter structure 4.

[0042] This embodiment sets up a cup body 1 and a cup lid body 2 that can rotate on the cup body 1, while simultaneously setting a filter structure 4 at the bottom of the cup lid body 2. This allows the operator to change the position of the filter structure 4 within the main cavity 101 of the cup body by rotating the cup lid body 2. This results in the collector body being in state one, where the inlet connector 11 is directly connected to the outlet connector 12, or in state two, where the inlet connector 11 is connected to the outlet connector 12 via the filter structure 4. This allows the operator to switch the collector's state as needed, achieving either collecting filtered polyps in state two or avoiding pressure loss due to airflow passing through the filter structure 4 in state one. This directly removes other useless residue, effectively solving the problems of the prior art.

[0043] In this embodiment, state two is... Figure 4 The polyp attraction state, state one is Figure 5 In other suction states, during the polyp suction state, the polyps drawn out of the body are mixed with wastewater and exhaust gas. The polyps can be filtered out and retained in the filter structure 4, while the wastewater and exhaust gas are discharged through the outlet connector 12, making it convenient to remove the polyps that are needed later. In other suction states, all substances drawn out of the body are discharged directly without passing through the filter structure 4. Due to the small amount of obstruction, the loss of suction pressure is also small.

[0044] In this embodiment, the system is in state two only when polyp collection is needed, typically extracting polyps, gas, and wastewater; when polyp collection is not needed, it is in state one, removing other useless debris and wastewater.

[0045] Therefore, this embodiment, through this state-switching concept, can simultaneously retain the advantages of easy polyp identification and collection and that the suction pressure will not be excessively lost, which is a significant technological advantage compared to existing technologies.

[0046] In addition, the structure of this embodiment is very simple, with low manufacturing and usage costs, and it is extremely easy to operate with a very low learning cost, making it convenient for widespread use.

[0047] Specifically, in this embodiment, the filter structure 4 includes a filter body 41 that is fixed vertically to the bottom of the cup lid body 2 along the axial direction of the cup lid body 2;

[0048] With the cup lid body 2 fastened to the cup body body 1, both ends of the filter body 41 are close to the inner peripheral wall of the cup body body 1, and the bottom of the filter body 41 is close to the bottom of the cup body body 1. This can prevent polyps from being discharged from the gap between the filter body 41 and the cup body body 1, and prevent polyps from being collected in place.

[0049] In this embodiment, the filter structure 4 is connected to the cup lid body 2 as one piece or is integrally molded.

[0050] Specifically, such as Figure 4 and Figure 5 As shown, in this embodiment, the angle between the lines connecting the two end faces of the filter body 41 and the central axis of the cup lid body 2 is less than 180°, so that after the filter body 41 and the cup body 1 form a collection cavity 401 for collecting polyps, the area and space occupied are less than half of the entire main cavity 101 of the cup body. This avoids the loss of suction pressure caused by the filter structure 4 and the adhesion of other useless residues to the filter structure when the collector body is in state one.

[0051] In an optional embodiment, the filter body 41 can be any one of curved, bent, or straight. In this embodiment, the filter body 41 is curved. Technicians can also choose a bent or straight filter body 41 as needed, which will not be elaborated here.

[0052] Specifically, the filter structure 4 also includes a base plate 42 fixed to the bottom of the filter body 41 and arranged parallel to the cup lid body 2;

[0053] The bottom plate 42, the filter body 41, and the inner peripheral wall of the cup body 1 can form a collection cavity 401 located in the main cavity 101 of the cup body;

[0054] The number of collection chambers 401 can be one or more;

[0055] The side of the base plate 42 near the main body 1 is an arc-shaped sidewall 421 that fits the inner peripheral wall of the main body 1. In this embodiment, by setting the base plate 42, after the collector has collected the polyp in state two, the main body 2 of the cup lid can be directly pulled out, and the polyp can be lifted by the base plate 42 to complete the removal of the polyp, making the polyp removal operation extremely convenient.

[0056] Specifically, in this embodiment, such as Figures 3 to 5 As shown, the inner peripheral wall of the cup body 1 is provided with a first limiting rib 13 and a second limiting rib 14 for confirming whether the collector body is in state one or state two.

[0057] The first limiting rib 13 and the second limiting rib 14 are located on both sides of the line connecting the inlet joint 11 and the outlet joint 12, respectively.

[0058] The filter structure 4 is located on the side of the first limiting rib 13 and the second limiting rib 14 near the inlet connector 11. By setting the first limiting rib 13 and the second limiting rib 14, the operator only needs to rotate the cup lid body 2 forward or backward and confirm that the rotation is in place to complete and confirm that the working state of the collector body has been switched. This not only makes the operation simple, but also makes it less prone to errors.

[0059] In this embodiment, the first limiting rib 13 and the second limiting rib 14 have the same structure, and can be replaced with other shaped protrusions, such as multiple vertically arranged protrusions. Technicians can set them as needed, which will not be elaborated here.

[0060] Specifically, in this embodiment, the filter structure 4 is an axisymmetric structure; when the filter structure 4 abuts against the first limiting rib 13, the central axis of the inlet connector 11 is directly opposite the central axis of symmetry of the filter structure 4, which can minimize the loss of suction pressure under polyp suction conditions and ensure the filtration effect.

[0061] Specifically, in this embodiment, such as Figure 1 , Figures 3 to 5 As shown, the inlet connector 11 and the outlet connector 12 are coaxially arranged and located on opposite sides of the cup body 1. The coaxial arrangement of the inlet connector 11 and the outlet connector 12 can minimize the loss of suction pressure.

[0062] Specifically, such as Figure 1 As shown, the inlet connector 11 is also provided with a connecting tube 3 for connecting to the endoscope suction port. In this embodiment, the connecting tube 3 is a plastic flexible tube.

[0063] Specifically, in this embodiment, such as Figure 1 and Figure 2 As shown, the side of the cup lid body 2 is provided with an anti-slip structure 201. In this embodiment, the anti-slip structure 201 is a groove structure. The anti-slip structure 201 can prevent slipping.

[0064] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
