Description

Technical Field

[0001] The utility model relates to the technical field of uterine endoscopes, in particular to a disposable uterine endoscope. Background Technique

[0002] The uterine endoscope, also known as the hysteroscope, is a new minimally invasive gynecological diagnosis and treatment technology. It is a fiber optic light source endoscope used for examination and treatment in the uterine cavity, including a hysteroscope, an energy system, a light source system, an irrigation system, and an imaging system. It uses the front part of the endoscope body to enter the uterine cavity and has a magnifying effect on the observed part, making it an intuitive and accurate preferred examination method for gynecological hemorrhagic diseases and intrauterine lesions.

[0003] Most existing disposable uterine endoscopes reach the interior of the uterus by inserting through the cervical orifice when examining patients. When examining deeper positions in the uterus, medical staff need to push the disposable uterine endoscope to move it to a deeper position. Frequent pushing of the disposable uterine endoscope will cause frequent friction between the disposable uterine endoscope and the uterine orifice, causing severe discomfort to the patient. Moreover, after the examination, the disposable uterine endoscope consumables need to be discarded to avoid cross-infection, and the installation of general consumable components is inconvenient.

[0004] Therefore, a disposable uterine endoscope is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a disposable uterine endoscope to solve the problems in the above background technique, that is, most existing disposable uterine endoscopes reach the interior of the uterus by inserting through the cervical orifice when examining patients. When examining deeper positions in the uterus, medical staff need to push the disposable uterine endoscope to move it to a deeper position. Frequent pushing of the disposable uterine endoscope will cause frequent friction between the disposable uterine endoscope and the uterine orifice, causing severe discomfort to the patient. Moreover, after the examination, the disposable uterine endoscope consumables need to be discarded to avoid cross-infection, and the installation of general consumable components is inconvenient.

[0028] As Figures 1 to 7As shown in the figure, a specific embodiment of the present utility model provides a disposable uterine endoscope, which includes a handle 1, a connecting block 2 provided on the handle 1, and a receiving rod 3 fixedly connected to the connecting block 2. A long rod 4 is provided in the receiving rod 3. A driving assembly for pushing the long rod 4 to move is provided between the long rod 4 and the receiving rod 3. By setting the driving assembly, the receiving rod 3 can be kept moving during the examination of the patient, and the long rod 4 in the receiving rod 3 is driven to move, so that the deeper position of the uterus can be examined. The driving assembly includes a threaded rod 5 rotatably connected in the receiving rod 3. A push plate 6 is threadedly connected to the threaded rod 5, and a connecting rod 7 is fixedly connected between the push plate 6 and the long rod 4. It also includes a clamping assembly provided on the handle 1 for quickly connecting the connecting block 2 and the handle 1. By setting the clamping assembly, the handle 1 can be disassembled after the disposable uterine endoscope is used, so that the components in direct contact with the patient except the handle 1 are discarded to prevent cross-infection. The handle 1 is not in direct contact with the patient, and the electronic components in the handle 1 are protected inside the handle 1, so that the electronic components can be removed for recycling. The clamping assembly includes a push rod 8 slidably connected to the handle 1. A clamping block 9 is fixedly connected to the push rod 8, and a spring 10 is fixedly connected between the clamping block 9 and the push rod 8.

[0029] As Figures 1 to 5As shown in the figure, specifically, a sealing plate 16 is fixedly connected to the receiving rod 3, and a conical sealing block 17 is fixedly connected to the sealing plate 16. The sealing plate 16 is slidably connected to the long rod 4. When examining a patient, the long rod 4 is inserted into the patient's uterus, so that the sealing block 17 is located at the uterine orifice. The sealing plate 16 is attached to the outer wall of the uterine orifice 2. The conical shape of the sealing block 17 facilitates the slow and gradual entry of the conical sealing block 17 of the sealing block 17 when the uterine orifice is relatively small. Thus, the elastic uterine orifice can closely adhere to the sealing block 17, enhancing the stability of the device during the examination. A guide groove 18 is provided in the long rod 4, and a camera 19 is fixedly connected to the end of the guide groove 18. A wire 20 is fixedly connected to the camera 19, and the wire 20 extends to the outside of the receiving rod 3. A plug 21 is fixedly connected to the wire 20. A socket 22 adapted to the plug 21 is provided on the handle 1. An external interface is provided on the handle 1. A circuit board is provided in the handle 1, which provides functions such as current supply and signal transmission. It is located inside the handle 1 and is connected to the external interface and the socket 22. The external interface is connected to an external connector, and the plug 21 is inserted into the socket 22. Thus, electricity conduction and data transmission are carried out on the camera 19 through the wire 20, and then the patient's uterus can be examined. A limiting groove 11 is provided in the receiving rod 3, and the push plate 6 is slidably connected in the limiting groove 11. A rotating plate 12 is fixedly connected to the threaded rod 5. When it is necessary to examine a deeper position of the uterus, the rotating plate 12 is rotated to drive the threaded rod 5 to rotate. Thus, under the cooperative action of the limiting groove 11, the push plate 6 pushes the connecting rod 7, causing the long rod 4 to move in the receiving rod 3, that is, the long rod 4 moves to a deeper position of the uterus. At this time, both the receiving rod 3 and the sealing block 17 can remain stationary, thus avoiding the discomfort caused to the patient by the frequent friction between the uterine orifice and the disposable hysteroscope when examining a deeper position of the uterus.

[0030] As Figures 1 to 5As shown in the figure, specifically, a water inlet channel 23 is provided in the long rod 4, and a water inlet pipe 24 communicating with the water inlet channel 23 is fixedly connected to the long rod 4. A number of spray nozzles communicating with the water inlet channel 23 are provided on the long rod 4. A water outlet channel 25 is provided in the long rod 4, and a water outlet pipe 26 communicating with the water outlet channel 25 is fixedly connected to the long rod 4. A groove is provided in the handle 1, and an elastic clip 27 is fixedly installed in the groove. The elastic clip 27 can limit and fix the water inlet pipe 24 and the water outlet pipe 26. The water inlet pipe 24 and the water outlet pipe 26 both extend into the groove, and the water inlet pipe 24 and the water outlet pipe 26 are both clamped in the elastic clip 27. Valves 28 are provided on both the water inlet pipe 24 and the water outlet pipe 26. When it is necessary to clean the inside of the patient's uterus for better examination, the water inlet pipe 24 is connected to an external diversion pipe, and the valve 28 on the water inlet pipe 24 is opened so that the external cleaning liquid enters the water inlet channel 23 through the water inlet pipe 24, and then sprays into the uterus through the spray nozzles, thereby cleaning it. During the cleaning process, the cleaning liquid after cleaning the uterus flows into the water outlet channel 25 and the water outlet pipe 26. When the cleaning liquid in the uterus is about to be full, the valve 28 on the water outlet pipe 26 is opened so that the cleaning liquid is discharged outward. During the outward liquid discharge process, the valve 28 on the water inlet pipe 24 is controlled so that the flow rate of the cleaning liquid flowing in inward is less than the speed of the cleaning liquid discharged outward. Until the cleaning liquid in the uterus is about to be drained, the valve 28 on the water inlet pipe 24 is closed, thereby preventing the cleaning liquid in the uterus from flowing back into the water inlet pipe 24. Both the water inlet pipe 24 and the water outlet pipe 26 are made of metal hoses. Sufficiently long water inlet pipes 24, water outlet pipes 26, and wires 20 are reserved in the inner cavity of the receiving rod 3. The purpose is that when the long rod 4 extends, it will drive the water inlet pipe 24, the water outlet pipe 26, and the wire 20 to move together, and the reserved length facilitates their movement along with the long rod 4 without affecting the water inlet pipe 24, the water outlet pipe 26, the wire 20, and the plug 21 that are externally limited and fixed to the receiving rod 3.

[0031] As Figures 5 to 7As shown, specifically, a square groove 13 is formed in the handle 1, and a receiving groove 14 is formed in the handle 1. A card slot 15 adapted to the clamping block 9 is formed in the connecting block 2. The clamping block 9 and the connecting block 2 are both provided with inclined surfaces at the same angle. Before the inspection is completed, when the new handle 1 is connected to the connecting block 2 and the components on the connecting block 2, the connecting block is inserted into the square groove 13. Since the clamping block 9 and the connecting block 2 are both provided with inclined surfaces at the same angle, the clamping block 9 is forced to move, and the spring 10 is forced to contract to generate a reaction force. Until the card slot 15 on the connecting block 2 moves to the position of the clamping block 9, the clamping block 9 is snapped into the card slot 15 under the reaction force of the spring 10. Then, the water inlet pipe 24 and the water outlet pipe 26 are snapped into the elastic clip 27, so as to complete the connection and fixation of the connecting block 2 and the components on its top on the handle 1. After the inspection is completed, the water inlet pipe 24 and the water outlet pipe 26 are pulled to disengage from the elastic clip 27, and the push rod 8 is pulled to make the clamping block 9 disengage from the card slot 15. At this time, the connecting block 2 and the top components can be taken out to be separated from the handle 1. All the consumable components except the handle 1 are discarded to avoid cross-infection. The handle 1 can be disinfected and then the internal circuit board components are taken out and the handle 1 is discarded, so as to recycle the taken-out circuit components.
