Description

Technical Field

[0001] This utility model relates to the field of endoscope technology, and in particular to an endoscope with an independent suction channel. Background Technology

[0002] Medical endoscopes, as one of the main diagnostic instruments in the medical field, can be inserted into human tissues or organs to transmit real-time images of the corresponding areas for diagnosis, and can insert appropriately sized instruments to achieve therapeutic functions. Cystoscopy, as a type of endoscope, can aid in the diagnosis and treatment of diseases of the urethra, bladder, ureters, and kidneys.

[0003] For example, an endoscope with publication number CN217659782U has a working channel end connected to the inlet of a connecting valve, and the outlet of the connecting valve connected to a suction pump. In addition to the passage of instruments, the working channel can also be used to extract accumulated fluid for testing. Especially when used as a cystoscope, the working channel is used to aspirate accumulated fluid in the bladder and other tissues to allow for clearer observation of the tissue condition.

[0004] The working channel requires an external connecting valve to achieve the suction function. Since there is only one working channel, it is impossible to achieve the function of simultaneously injecting and sucking water, resulting in poor efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an endoscope with an independent suction channel. The working channel and the suction channel can work independently, enabling the simultaneous injection and suction of water, thus improving efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An endoscope with an independent suction channel includes:

[0008] A handle assembly, the surface of which is provided with a working channel inlet and a suction channel inlet;

[0009] An insertion component includes a head end, on which a first hole and a second hole are formed. The bottom of the first hole is at a lower level than the bottom of the second hole. A working channel outlet is provided at the bottom of the first hole. The cross-sectional area of ​​the first hole is equal to the cross-sectional area of ​​the working channel outlet. One radial side of the second hole communicates with the first hole, and the other radial side of the second hole is provided with a suction channel outlet.

[0010] A working channel tube is disposed inside the insertion assembly and is connected between the working channel inlet and the working channel outlet;

[0011] A suction channel tube is disposed inside the insertion assembly and is connected between the suction channel inlet and the suction channel outlet.

[0012] In a preferred embodiment, the head end portion includes:

[0013] The top surface of the head end is partially recessed to form the first hole and the second hole;

[0014] The head end side is connected to the edge of the top surface of the head end.

[0015] In a preferred embodiment, the top surface of the head end includes:

[0016] First impression;

[0017] The second surface is connected between the first surface and the head end side surface. The second surface is arc-shaped and inclined. The first hole and the second hole are formed on the second surface.

[0018] In a preferred embodiment, at least a portion of the edges of the suction channel outlet are rounded.

[0019] In a preferred embodiment, the cross-sectional area of ​​the working channel tube is larger than the cross-sectional area of ​​the suction channel tube.

[0020] In a preferred embodiment, the insertion component further includes:

[0021] A curved portion, the curved portion connecting the head end and the insertion tube;

[0022] An insertion tube is connected between the bend and the handle assembly.

[0023] In a preferred embodiment, the side of the handle assembly includes a flat surface and an inclined surface, with the suction channel inlet provided on the flat surface and the working channel inlet provided on the inclined surface.

[0024] In a preferred embodiment, the plane is located between the inclined surface and the insertion component.

[0025] In a preferred embodiment, the working channel inlet is configured as a connector that snaps onto the surface of the handle assembly;

[0026] The suction channel inlet is configured as a connector that snaps onto the surface of the handle assembly.

[0027] In a preferred embodiment, the connector includes an upper section, a middle section, and a lower section, with the middle section connecting the upper section and the lower section, and the lower section being engaged within the handle assembly.

[0028] Compared with existing technologies, this technical solution has the following advantages:

[0029] The working channel pipe and the suction channel pipe are independent of each other, and the working channel pipe can be filled with water and the suction channel pipe can be sucked up at the same time, which effectively improves the efficiency of use.

[0030] When the instrument is led out from the working channel outlet and passes through the first hole, the second hole and the suction channel outlet are not blocked by the instrument. Therefore, when the instrument operates on the tissue, it will not affect the water absorption operation of the suction channel tube, thus ensuring the suction effect.

Detailed Implementation

[0037] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0038] like Figures 1 to 3As shown, the endoscope with an independent suction channel includes:

[0039] Handle assembly 100, the surface of which is provided with a working channel inlet 300a and a suction channel inlet 400a;

[0040] An insertion component 200 includes a head end 210, on which a first hole 210a and a second hole 210b are formed. The bottom of the first hole 210a is at a lower level than the bottom of the second hole 210b. A working channel outlet 300b is provided at the bottom of the first hole 210a. The cross-sectional area of ​​the first hole 210a is equal to the cross-sectional area of ​​the working channel outlet 300b. One radial side of the second hole 210b communicates with the first hole 210a, and the other radial side of the second hole 210b is provided with a suction channel outlet 400b.

[0041] A working channel tube 300 is disposed inside the insertion assembly 200 and is connected between the working channel inlet 300a and the working channel outlet 300b.

[0042] A suction channel tube 400 is disposed inside the insertion assembly 200 and is connected between the suction channel inlet 400a and the suction channel outlet 400b.

[0043] The working channel tube 300 can be used for instrument introduction and water injection, while the suction channel tube 400 is used for tissue aspiration. When the insertion assembly 200 is placed inside the body cavity and the handle assembly 100 is located outside the body cavity, the instrument can be introduced from the working channel inlet 300a, pass through the working channel tube 300, and be led out from the working channel outlet 300b to operate on the tissue within the body cavity. Simultaneously, fluid accumulated in the body cavity can enter the suction channel tube 400 from the suction channel outlet 400b and flow out from the suction channel inlet 400a. It is evident that the working channel tube 300 and the suction channel tube 400 are independent of each other, allowing for simultaneous water injection into the working channel tube 300 and water aspiration into the suction channel tube 400, effectively improving efficiency. In addition, when the instrument is led out from the working channel outlet 300b and passes through the first hole 210a, the second hole 210b and the suction channel outlet 400b are not blocked by the instrument. Therefore, when the instrument operates on the tissue, it will not affect the water absorption operation of the suction channel tube 400, thus ensuring the suction effect.

[0044] like Figure 1As shown, the handle assembly 100 serves as a handheld component for medical personnel. Its side includes a plane 110 and an inclined plane 120. The suction channel inlet 400a is provided on the plane 110, and the working channel inlet 300a is provided on the inclined plane 120. That is, by setting the suction channel inlet 400a and the working channel inlet 300a at different angles, interference between the suction channel inlet 400a and the working channel inlet 300a is effectively prevented.

[0045] In this embodiment, the plane 110 is located between the inclined surface 120 and the insertion component 200.

[0046] refer to Figure 1 The working channel inlet 300a is configured as a connector 500 that snaps onto the surface of the handle assembly 100; the suction channel inlet 400a is configured as a connector 500 that snaps onto the surface of the handle assembly 100.

[0047] refer to Figure 4 The connector 500 includes an upper section 520, a middle section 510, and a lower section 530. The middle section 510 is connected between the upper section 520 and the lower section 530. The upper section 520, the middle section 510, and the lower section 530 have holes in their centers and are connected in sequence. Taking the connector as the inlet 400a of the suction channel as an example, the accumulated liquid drawn from the suction channel tube 400 can pass through the lower section 530, the middle section 510, and the upper section 520 in sequence.

[0048] Furthermore, the cross-sectional areas of the upper section 520 and the lower section 530 are respectively larger than the cross-sectional area of ​​the middle section 510. The upper section 520, which serves as the connector for the suction channel inlet 400a, is provided with external threads, which can be used to connect external pipes or valves, etc., for draining accumulated liquid. The lower section 530 is fitted inside the handle assembly 100, serving the purpose of fixing the connector 500 to the handle assembly 100. The handle assembly 100 can be divided into two parts, which hold the lower section 530 together and are fixed by screws, etc., to secure the lower section 530 inside the handle assembly 100.

[0049] refer to Figure 1 and Figure 3 The working channel tube 300 is used for instrument insertion, and the suction channel tube 400 is used for draining accumulated fluid. Therefore, the cross-sectional area of ​​the working channel tube 300 is larger than the cross-sectional area of ​​the suction channel tube 400.

[0050] Preferably, the working channel tube 300 is partially bent inside the handle assembly 100, and a bending groove 130 is provided inside the handle assembly 100 to hold the bent portion of the working channel tube 300, ensuring the stability of the working channel tube 300 inside the handle assembly 100. The bending groove can be integrally connected to the handle assembly 100, or the bending groove can be fixed inside the handle assembly 100 by screws.

[0051] like Figure 1 and Figure 2 As shown, the insertion component 200 further includes:

[0052] A bend 220 is connected between the head end 210 and the insertion tube 230;

[0053] Insertion tube 230, which is connected between the bend 220 and the handle assembly 100.

[0054] like Figure 2 As shown, the head end portion 210 includes:

[0055] The top surface 211 of the head end is partially recessed to form the first hole 210a and the second hole 210b.

[0056] The head end side surface 212 is connected to the edge of the head end top surface 211.

[0057] The head end side 212 is connected between the head end top surface 211 and the curved portion 220. Since the first hole 210a and the second hole 210b are provided on the head end top surface 211, the instrument can be led out from the first hole 210a of the head end top surface 211, and the tissue fluid is introduced into the suction channel tube 400 from the second hole 210b of the head end top surface 211.

[0058] refer to Figure 2 The top surface 211 of the head end includes:

[0059] Page 211a;

[0060] The second surface 211b is connected between the first surface 211a and the head end side surface 212. The second surface 211b is arc-shaped and inclined. The first hole 210a and the second hole 210b are formed on the second surface 211b.

[0061] A camera 211a1 is provided on the first surface 211a, and the first hole 210a and the second hole 210b are provided on the second surface 211b. The second surface 211b is inclined to make reasonable use of space and avoid mutual interference.

[0062] The first surface 211a is approximately elliptical, and the second surface 211b is arc-shaped and surrounds half of the first surface 211a.

[0063] Continue to refer to Figure 2 The first hole 210a corresponds to the working channel outlet 300b, and both have equal cross-sectional areas, wherein the cross-sections of the first hole 210a and the working channel outlet 300b are circular. When the instrument is drawn out from the working channel outlet 300b and passes through the first hole 210a, the second hole 210b and its inner wall's suction channel outlet 400b are exposed, so tissue fluid can be introduced from the suction channel outlet 400b into the suction channel tube 400 and then discharged.

[0064] The suction channel outlet 400b is located near the top surface 211 of the head end, and at least part of its edges are rounded 400b1. In this way, the cross-section of the suction channel outlet 400b gradually decreases from the outside to the inside, which is beneficial for introducing tissue fluid.

[0065] In summary, the endoscope with an independent suction channel can be used as a cystoscope. The working channel tube 300 and the suction channel tube 400 are independent of each other, allowing simultaneous water injection into the working channel tube 300 and water suction into the suction channel tube 400, effectively improving efficiency. Furthermore, when the instrument is led out from the working channel outlet 300b and passes through the first hole 210a, the second hole 210b and the suction channel outlet 400b are not obstructed by the instrument. Therefore, when the instrument is working on tissue, it will not affect the water suction operation of the suction channel tube 400, ensuring the effectiveness of suction.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. The scope of patent application of this utility model should not be limited by these embodiments.
