Technical Field

[0001] The invention relates to the technical field of hysteroscopes, and in particular to a disposable hysteroscope structure. Background Art

[0002] A disposable hysteroscope is a medical device used for gynecological examination and treatment. It is mainly used to observe and diagnose lesions of gynecological organs such as the uterus, cervix, and fallopian tubes, as well as to perform some therapeutic operations. Compared with traditional hysteroscopes, disposable hysteroscopes are more convenient, hygienic, and safer.

[0003] The following are some of the features and uses of disposable hysteroscopes:

[0004] Disposable use: Disposable hysteroscopes are usually composed of disposable instruments, including lenses, light sources, connecting wires, etc., which can be discarded after use without the need for cleaning and disinfection, reducing the risk of cross infection and improving the hygiene of the operation.

[0005] High-definition imaging: The disposable hysteroscope is equipped with a high-definition camera and light source system, which can provide clear images and videos. Doctors can observe the condition of the examination site in real time through the display screen, so as to make more accurate diagnosis and treatment.

[0006] In general, disposable hysteroscope is an advanced medical device with the advantages of accurate diagnosis, good treatment effect, simple operation, safety and reliability, and has been widely used in gynecological clinical work.

[0007] Before using a disposable hysteroscope, lubricant is usually applied manually to reduce patient discomfort and facilitate insertion and manipulation of the instrument.

[0034] like Figure 1-Figure 8 The disposable hysteroscope structure shown includes a handle 1, an insertion end 2, and a cable assembly 3. The insertion end 2 is clamped at one end of the handle 1, and the cable assembly 3 is connected at one end of the handle 1. The handle 1 is mainly composed of six parts: a front 90° steering mechanism, a snake bone drive assembly, a connection assembly, a key board assembly, a light source assembly, and a shell. The insertion end 2 includes a tip seat, a camera assembly, an optical fiber assembly, a clamp channel tube, and two water channels. The cable assembly 3 includes a handle line, an SR connector, a relay board, and a connector.

[0035] The handle 1 is connected and fixed with a fixing seat 4, the fixing seat 4 is connected and fixed with a guide ring 5, the guide ring 5 is connected and fixed with a driving mechanism 6, the guide ring 5 is rotatably connected with a ring frame 7, two cotton swab fixing mechanisms 8 are connected and fixed on the ring frame 7, and the guide ring 5 is connected and fixed with a liquid extraction mechanism 9.

[0036] like Figure 4 As shown, a liquid adding seat 401 is fixedly connected to the fixing seat 4, and a sealing cover 402 is threadedly connected to the liquid adding seat 401. The liquid adding seat 401 stores the lubricating liquid, and the sealing cover 402 seals the opening of the liquid adding seat 401.

[0037] like Figure 8As shown, the liquid extraction mechanism 9 includes a liquid extraction tube 901, which is connected and fixed to the guide ring 5, and the output end of the liquid extraction tube 901 is connected and fixed with a liquid adding tube 902, and the input end of the liquid extraction tube 901 is connected and fixed with a liquid guide tube 903, and the other end of the liquid guide tube 903 extends to the inner wall of the liquid adding seat 401 for communication, and the inner wall of the liquid extraction tube 901 is provided with a pumping and pressing plug 904 in a sliding manner, and one end of the pumping and pressing plug 904 is connected and fixed with a plug rod 906, and the outer end of the plug rod 906 is rotatably connected and provided with a push-pull rod 905. A one-way valve is installed in the input and output ends of the liquid extraction tube 901, and the model of the one-way valve is a spring ball valve. The spring-type one-way valve uses the pressure of the spring to control the opening and closing of the valve. When the fluid flows in the forward direction, the valve is subjected to the fluid pressure to open the passage; and when it flows in the reverse direction, the pressure of the spring will close the valve to prevent backflow.

[0038] like Figure 5 , Figure 6 As shown, a limiting groove 501 is provided on one side of the guide ring 5 close to the annular frame 7. The limiting groove 501 realizes the rotation of the annular frame 7.

[0039] A limit ring 701 is fixedly connected to one end of the annular frame 7, and the outer wall of the limit ring 701 is rotatably connected to the inner wall of the limit groove 501. An annular rack 702 is fixedly connected to the limit ring 701. The annular frame 7 realizes the function of driving the cotton swab fixing mechanism 8 to rotate.

[0040] like Figure 7 As shown, the driving mechanism 6 includes a motor 601, which is fixedly connected to the guide ring 5, a worm 602 is fixedly connected to the output end of the motor 601, a driving wheel 603 is fixedly connected to one end of the worm 602, and the driving wheel 603 is meshed with the annular rack 702 for transmission. The driving wheel 603 drives the annular frame 7 to rotate.

[0041] A worm wheel 604 is meshed and driven on one side of the worm 602, a fixed rod 606 is rotatably connected to one end of the worm wheel 604, the other end of the fixed rod 606 is fixedly connected to the guide ring 5, a connecting rod 605 is fixedly connected to the worm wheel 604, and the connecting rod 605 is rotatably connected to the other end of the push-pull rod 905. The connecting rod 605 drives the push-pull rod 905 to push and pull reciprocatingly.

[0042] like Figure 6 As shown, the cotton swab fixing mechanism 8 includes a fixing block 801, which is connected and fixed to the annular frame 7, a fixing sleeve 802 is rotatably connected to the fixing block 801, a plurality of clamping rods 803 are slidably provided on the inner wall of the fixing sleeve 802, a spring 804 is connected and fixed between the clamping rod 803 and the fixing sleeve 802, and a cotton swab 805 is clamped between the clamping rods 803. The spring 804 realizes the clamping effect of the clamping rod 803 on the cotton swab 805.

[0043] A sliding rod 806 is provided at one end of the fixed block 801 in a sliding cooperation, an adjusting rack 807 is connected and fixedly provided at one end of the sliding rod 806, a tension spring 808 is connected and fixedly provided between the adjusting rack 807 and the fixed block 801, an adjusting wheel 809 is connected and fixedly provided at one end of the fixed sleeve 802, and the adjusting wheel 809 is meshed and transmission-set with the adjusting rack 807. The tension spring 808 enables the fixed sleeve 802 to have an adjustable angle.

[0044] When a disposable hysteroscope is needed, the disposable cotton swab 805 is first inserted into the fixing sleeve 802. At this time, the spring 804 drives the clamping rod 803 to clamp and fix the disposable cotton swab 805. Then, under the action of the tension spring 808, the adjusting rack 807 drives the fixing sleeve 802 connected to the adjusting wheel 809 to maintain an inclined state.

[0045] Then the insertion end 2 of the disposable hysteroscope is passed through the guide ring 5, and the motor 601 is used to drive the worm 602 to rotate, so that the worm 602 drives the worm wheel 604 to rotate, and then the worm wheel 604 drives the push-pull rod 905 connected to the connecting rod 605, so that the push-pull rod 905 drives the pumping plug 904 connected to the plug rod 906 to move back and forth, so that the lubricating liquid in the liquid adding seat 401 is sucked into the liquid extraction tube 901 through the liquid guide tube 903, and then squeezed out through the liquid adding tube 902 and dripped onto the insertion end 2;

[0046] Then the driving wheel 603 connected to the worm 602 will drive the limiting ring 701 connected to the annular rack 702, thereby driving the annular frame 7 to rotate forward and reverse, so that the disposable cotton swab 805 continuously and evenly applies the lubricant on the insertion end 2, and then connects the insertion end 2 to the handle 1, and then inserts the insertion end 2 into the patient's body for examination.
