Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a disposable operation portable electronic uterine cavity imaging catheter. Background Art

[0002] A disposable electronic uterine cavity imaging catheter is a professional device applied in the medical field, especially for uterine cavity related examinations and treatments. It can penetrate deep into the uterine cavity and use advanced technology to obtain image information inside the uterine cavity. The front end of its handle is equipped with a lens and an LED light source. The lens is like the "eyes" of a doctor, which can clearly capture the subtle conditions inside the uterine cavity, such as the morphology of the endometrium and the presence of diseased tissues. These image information provide crucial and intuitive basis for doctors to accurately diagnose uterine cavity diseases, such as endometrial polyps, uterine cavity adhesions, etc.

[0003] The bottom of the handle of the existing electronic uterine cavity imaging catheter usually has a liquid inlet pipe and a liquid outlet pipe, and is equipped with a switch valve. During actual use, doctors need to independently control its switch with the other hand respectively, and often achieve the switch effect by turning the valve. During the operation, the operation is very inconvenient, and the switch efficiency of the valve is relatively low, and it is impossible to quickly and conveniently achieve independent control of the liquid inlet pipe and the liquid outlet pipe respectively. Summary of the Invention

[0005] Its purpose is to independently regulate the opening and closing of the liquid inlet pipe and the liquid outlet pipe by pressing the locking component, accurately control the inflow and outflow of the liquid, and achieve quick and convenient control of the inflow and outflow of the liquid.

[0006] The technical solution of the present invention is a disposable operation portable electronic uterine cavity imaging catheter, including a handle, an intubation tube provided at one end of the handle, a button provided on the handle, and a liquid inlet pipe and a liquid outlet pipe provided at the bottom of the handle, and further including a control unit provided inside the handle;

[0007] The control unit includes two control components provided inside the handle; the control component includes a valve assembly provided inside the handle, and a locking component provided on one side of the valve assembly;

[0008] The valve assembly is used to control the inflow and outflow of the liquid in the liquid inlet pipe and the liquid outlet pipe, and the locking component is used to squeeze and push the valve assembly to release the squeezing and blocking of the valve assembly on the liquid inlet pipe and the liquid outlet pipe;

[0009] The valve assembly includes a valve plate disposed inside the handle, a pressing hole opened on one side of the middle of the valve plate, a pressing groove opened on the side wall of the pressing hole, a pressing plate disposed at one end of the valve plate, a pressing block disposed on one side of the pressing plate, and a liquid inlet pipe and a liquid outlet pipe are respectively disposed in two corresponding pressing holes.

[0010] Further, the pressing plate is in a shape of a minor arc, and the pressing block is in an arc shape matching the pressing groove.

[0011] Further, the valve assembly further includes a rotating groove opened on one side of the pressing plate, a rotating column disposed in the rotating groove, and a torsion spring disposed between the rotating column and the pressing plate.

[0012] Further, the valve assembly further includes a moving groove disposed on one side of the pressing groove, a reset block disposed in the moving groove, and the liquid inlet pipe or the liquid outlet pipe is disposed at the middle position between the reset block and the pressing hole, a pressing inclined surface disposed on one side of the reset block, a reset column disposed on one side of the reset block, a reset spring disposed on one side of the reset column, and the reset spring is disposed inside the pressing plate.

[0013] Further, the locking assembly includes a button disposed on one side of the handle, a push rod disposed on one side of the button, a rotating head disposed at one end of the push rod through a torsion spring, a locking spring disposed inside one side of the rotating head, a locking rod disposed on one side of the locking spring, the locking rod is movably disposed inside the rotating head, a pressing rod disposed on the top of the push rod, and the pressing rod abuts against the back surface of the pressing plate, a mounting block disposed inside the handle, and an unlocking groove group opened on one side of the mounting block, and the locking rod is movably located in the unlocking groove group.

[0014] Further, the unlocking groove group includes a sliding groove opened on one side of the mounting block, a clamping groove opened on one side of the sliding groove, a rotating arc surface disposed on one side of the clamping groove, a convex edge disposed at the end of the clamping groove, a reset groove disposed on one side of the convex edge, and a reset arc surface opened on the other side of the reset groove and smoothly connected to the sliding groove.

[0015] Further, an arc-shaped sliding hole is opened on the side of the valve plate opposite to the pressing hole.

[0016] Further, two limiting plates for limiting the liquid inlet pipe and the liquid outlet pipe in the horizontal direction are disposed inside the handle, and the liquid inlet pipe and the liquid outlet pipe penetrate through the middle of the limiting plates.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By pressing the locking component, the opening and closing of the liquid inlet pipe and the liquid outlet pipe can be independently regulated. In actual medical operations, doctors can accurately control the inflow and outflow of liquid according to the specific conditions in the uterine cavity, such as the needs of irrigation and drug injection. This precise control avoids unnecessary liquid flow, reduces the risk of infection, improves the treatment effect, and enhances the accuracy and safety of medical operations.

[0019] 2. Due to the ingenious design of the torsion spring, the extrusion plate can automatically reset and open the pipeline after completing the extrusion and sealing. This automatic reset function saves the time and energy of medical staff in manual operations during multiple liquid inlet and outlet operation processes, improving work efficiency. Moreover, the stable automatic reset mechanism ensures the consistency of each operation and reduces the possibility of human operation errors.

[0020] 3. Structures such as the reset block, reset column, and reset spring provide comprehensive protection for the liquid inlet pipe. When the liquid inlet pipe is squeezed, they prevent the premature aging and damage of the liquid inlet pipe caused by multi-directional stress, extend the service life of the liquid inlet pipe, and reduce the replacement cost. At the same time, during the stage when the liquid inlet pipe returns to its original state, these structures can help it quickly recover, enabling the liquid to quickly reach the maximum flow rate and ensuring the efficient progress of the operation process.

[0021] 4. The front end of the handle is equipped with a front-end CMOS lens and a dual-LED light source, which has a million pixels and clear imaging, meeting clinical needs. The button has the function of an integrated handle key, realizing taking pictures and videos at the handle end, improving the convenience of use. The control unit can independently control whether the liquid inlet pipe and the liquid outlet pipe are closed respectively, with convenient operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will give a detailed description of the specific implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0034] Example 1, referring to Figures 1-9 , which is the first embodiment of the present invention, provides a disposable operation portable electronic intrauterine imaging catheter, including a handle 1, an insertion tube 2 installed at one end of the handle 1, a button 3 installed on the handle 1, and a liquid inlet tube 4 and a liquid outlet tube 5 installed at the bottom of the handle 1, and further includes a control unit installed inside the handle 1; the control unit includes two control components installed inside the handle 1; the control component includes a valve assembly installed inside the handle 1 and a locking assembly installed on one side of the valve assembly; the valve assembly is used to control the inflow and outflow of liquid in the liquid inlet tube 4 and the liquid outlet tube 5, and the locking assembly is used to extrude and push the valve assembly to release the extrusion and blockage of the liquid inlet tube 4 and the liquid outlet tube 5 by the valve assembly; the valve assembly includes a valve plate 6 fixedly connected inside the handle 1, an extrusion hole 7 opened on one side of the middle of the valve plate 6, an extrusion groove 8 opened on the side wall of the extrusion hole 7, an extrusion plate 9 rotatably connected to one end of the valve plate 6, an extrusion block 10 fixedly connected to one side of the extrusion plate 9, and the liquid inlet tube 4 and the liquid outlet tube 5 are respectively arranged in the corresponding two extrusion holes 7.

[0035] Specifically, the front end of the handle 1 is equipped with a top-end CMOS lens and a dual LED light source, which has millions of pixels and clear imaging to meet clinical needs. The button 3 has the function of the integrated button 18 of the handle 1, which enables taking photos and recording videos at the end of the handle 1, improving the convenience of use. The control unit can independently control whether the liquid inlet pipe 4 and the liquid outlet pipe 5 are closed, which is easy to operate. During specific use, when it is necessary to control the switch of the liquid inlet pipe 4 or the liquid outlet pipe 5, the independent adjustment of the liquid inlet and liquid outlet can be achieved by pressing the locking assembly separately. When the locking assembly is pressed, the valve assembly is pushed, so that the extrusion plate 9 is pushed to rotate, and the extrusion block 10 squeezes the liquid inlet pipe 4, so that the liquid inlet pipe 4 is squeezed into the extrusion groove 8. Since the extrusion groove 8 and the extrusion block 10 match, the liquid inlet pipe 4 can be squeezed and deformed and then bent, thereby achieving the blocking of the liquid inlet pipe 4. The liquid inlet pipe 4 and the liquid outlet pipe 5 are both deformable rubber tubes. The extrusion hole 7 is used to limit the liquid inlet pipe 4, which is convenient for the precise extrusion of the extrusion block 10.

[0036] Reference Figures 5-6 , the extrusion plate 9 is in an inferior arc shape, and the extrusion block 10 is in an arc shape that matches the extrusion groove 8.

[0037] Specifically, the inferior arc-shaped extrusion plate 9 allows the extrusion plate 9 to be pushed and rotated when the locking assembly pushes and squeezes its back position, and the extrusion block 10 and the extrusion groove 8 are both of matching arc shapes, thereby achieving complete blocking of the liquid inlet pipe 4 after extrusion. When the extrusion block 10 is driven by the extrusion plate 9 to reset and rotate, the liquid inlet pipe 4 will tend to return to its original shape, so that the liquid in the liquid inlet pipe 4 can flow smoothly, thereby achieving control over the liquid in the liquid inlet pipe 4.

[0038] Reference Figure 6 The valve assembly also includes a rotating groove 11 opened on one side of the extrusion plate 9, a rotating column 12 fixedly connected to the rotating groove 11, and a torsion spring abutting between the rotating column 12 and the extrusion plate 9 (the torsion spring has a torsion and reset function, not shown in the figure, and the same applies to the following).

[0039] Specifically, when the extrusion plate 9 is pushed to rotate, the torsion spring between the extrusion plate 9 and the rotating column 12 will be twisted and force will be stored. When the extrusion plate 9 stops being pushed, under the reset force of the torsion spring, the extrusion plate 9 will reset and rotate, thereby realizing the automatic opening of the liquid inlet pipe 4.

[0040] Reference Figures 1-6 The valve assembly also includes a movable groove 13 opened on one side of the extrusion groove 8, a reset block 14 slidably connected to the movable groove 13, and the liquid inlet pipe 4 or the liquid outlet pipe 5 is arranged at the middle position between the reset block 14 and the extrusion hole 7, an extrusion inclined surface 15 opened on one side of the reset block 14, a reset column 16 fixedly connected to one side of the reset block 14, a reset spring 17 fixedly connected to one side of the reset column 16, and the reset spring 17 is fixedly connected to the inside of the extrusion plate 9.

[0041] Specifically, when the extrusion plate 9 rotates during extrusion, the hypotenuse of the extrusion block 10 will first push the extrusion inclined surface 15, causing the entire reset block 14 to contract into the movable groove 13. After pushing the reset block 14, the extrusion block 10 then extrudes the liquid inlet pipe 4. When the liquid inlet pipe 4 is extruded, its extruded surface will become flat and concave, and the folding sides on both sides will fold and extend to both sides. The above design can prevent the folding sides of the liquid inlet pipe 4 from being blocked and extruded by the reset block 14 when extending, which can not only ensure the smooth extension of the folding sides of the liquid inlet pipe 4, but also prevent the folding sides of the liquid inlet pipe 4 from being stressed and extruded when the extruded surface of the liquid inlet pipe 4 is deformed by extrusion, preventing the liquid inlet pipe 4 from being stressed in multiple directions and avoiding the aging and damage of the liquid inlet pipe 4 under long-term extrusion. This not only improves the sealing performance of the liquid inlet pipe 4 during plugging, but also extends the service life of the liquid inlet pipe 4, thereby improving the service life, stability and safety of the entire device. When the extrusion block 10 stops extruding the extruded surface of the liquid inlet pipe 4, the liquid inlet pipe 4 tends to return to its original shape due to deformation, but due to long-term extrusion, the folding sides on both sides cannot quickly and completely restore the cylindrical shape of the liquid inlet pipe 4. When the return spring 17 returns to its original position, it will push the reset block 14 to extrude and push the liquid inlet pipe 4, enabling the liquid inlet pipe 4 to quickly return to its original shape, ensuring that the liquid inside the liquid inlet pipe 4 can smoothly reach the maximum flow rate quickly, and ensuring that the folding sides of the liquid inlet pipe 4 always maintain the balance and stability between compressive deformation and deformation recovery.

[0042] Embodiment 2, referring to Figures 1-4 and Figures 7-9 is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the locking assembly includes a button 18 that is limited and slidably connected to one side of the handle 1. The two buttons 18 are in a stepped shape for easy separate pressing by the doctor. A push rod 19 fixedly connected to one side of the button 18, a rotating head 20 rotatably connected to one end of the push rod 19 through a torsion spring, a locking spring 21 fixedly connected to the inside of one side of the rotating head 20, a locking rod 22 fixedly connected to one side of the locking spring 21. The locking rod 22 is slidably connected to the inside of the rotating head 20, an extrusion rod 23 fixedly connected to the top of the push rod 19, and the extrusion rod 23 abuts against the back surface of the extrusion plate 9. An installation block 24 fixedly connected to the inside of the handle 1, and an unlocking groove group opened on one side of the installation block 24. The locking rod 22 is located and moves within the unlocking groove group.

[0043] Specifically, the locking assembly is used to lock and unlock the valve assembly. When the medical staff presses the button 18, the button 18 will drive the push rod 19 to move, and the moving rod will synchronously drive the extrusion rod 23 to move, so that the extrusion rod 23 squeezes and pushes the extrusion plate 9, thereby realizing that the extrusion plate 9 drives the extrusion block 10 to squeeze and seal the liquid inlet pipe 4. In the initial state, the back positions of the extrusion rod 23 and the extrusion plate 9 are in abutment state. During the process of pressing the button 18, the locking rod 22 in the rotating head 20 will move in the unlocking groove group, realizing the abutment locking and sliding reset unlocking of the locking rod 22.

[0044] Reference Figure 8 The unlocking groove group includes a sliding groove 25 opened on one side of the mounting block 24, a clamping groove 26 opened on one side of the sliding groove 25, a rotating arc surface 27 opened on one side of the clamping groove 26, a convex edge 28 fixedly connected to the end of the clamping groove 26, a reset groove 29 opened on one side of the convex edge 28, and a reset arc surface 30 opened on the other side of the reset groove 29 and smoothly connected to the sliding groove 25.

[0045] Specifically, when the push rod 19 is pushed and moved, the rotating head 20 and the locking rod 22 inside it are pushed and moved synchronously, so that the locking rod 22 moves in the sliding groove 25. When it moves into the engaging groove 26, under the action of the locking spring 21, the locking rod 22 is clamped into the engaging groove 26. At this time, the squeezing plate 9 is squeezed and rotated to squeeze and block the liquid inlet pipe 4, and under the reverse squeezing force of the squeezing plate 9, the locking rod 22 is firmly locked in the engaging groove 26. When the liquid inlet pipe 4 is unblocked, the button 18 is pressed again to make the push rod 19 continue to move. At this time, the locking rod 22 slides along the rotating arc surface 27, so that the locking rod 22 drives the rotating head 20 to twist the torsion spring and rotate obliquely upward. When it reaches the convex edge 28, the locking rod 22 presses The locking spring 21 is compressed, so that the locking rod 22 can turn over the convex edge 28 and enter the reset groove 29. At this time, the locking rod 22 extends under the reset action of the locking spring 21, and slides obliquely against the reset groove 29. At this time, the pressing of the button 18 is stopped, and under the action of the torsion spring reset force at the extrusion plate 9, the extrusion rod 23 is automatically pushed backward, so that the rotating head 20 and the locking rod 22 are reset and moved synchronously, and under the action of the reset arc surface 30, the torsion spring inside the rotating head 20 drives the rotating head 20 to reset and rotate on the reset arc surface 30, so that the locking rod 22 rotates to the initial state again. At this point, the complete press-lock and press-reset function is realized, the structure is simple, the operation is convenient, and it has high practicality of locking and unlocking.

[0046] Reference Figures 5-6 An arc-shaped sliding hole 31 is provided on the side of the valve plate 6 opposite to the extrusion hole 7.

[0047] Specifically, the design of the arc-shaped sliding hole 31 facilitates the slight expansion and contraction of the liquid inlet pipe 4 and the liquid outlet pipe 5 when they are squeezed and blocked, avoiding damage to the pipe walls of the liquid inlet pipe 4 and the liquid outlet pipe 5 and reducing the friction of their expansion and contraction.

[0048] Referring to Figure 2 , two limiting plates 32 for limiting the liquid inlet pipe 4 and the liquid outlet pipe 5 in the horizontal direction are fixedly connected inside the handle 1, and the liquid inlet pipe 4 and the liquid outlet pipe 5 penetrate through the middle parts of the limiting plates 32.

[0049] Specifically, the limiting plate 32 is used to limit the horizontal positions of the liquid inlet pipe 4 and the liquid outlet pipe 5, avoiding their bending and facilitating installation and blocking. The rest of the structure is the same as that of Embodiment 1.

[0050] Combining Embodiments 1-2, the working principle of the present invention is as follows: By pressing the locking component, the pressing plate 9 in the valve component is pushed to rotate. The pressing block 10 on the pressing plate 9 squeezes the liquid inlet pipe 4 or the liquid outlet pipe 5 into the pressing groove 8, causing it to bend and block, realizing the independent control of liquid inlet and outlet. The operation is extremely convenient, and the liquid flow can be accurately regulated. At the same time, when the pressing plate 9 rotates, the torsion spring connected to it stores energy. After stopping pressing, the torsion spring resets and drives the pressing plate 9 to turn back, automatically opening the pipeline. In addition, structures such as the reset block 14, the reset post 16, and the reset spring 17 can prevent the liquid inlet pipe 4 from being subjected to multi-directional forces when being squeezed, extend its service life, and assist the liquid inlet pipe 4 to quickly return to its original state, ensuring that the liquid quickly reaches the maximum flow rate. The locking rod 22 in the locking component moves in the unlocking groove group to achieve pressing and locking and pressing again to unlock. The structure is simple, improving the operation convenience and practicality.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
