Detailed Implementation

[0037] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0038] See appendix Figure 1-4 This utility model discloses a dual-cavity vaginal examination instrument, including: a monitoring unit 1, a spray gun 2, and biopsy forceps 3;

[0039] The monitoring unit 1 includes a support rod 11 and a camera device 12. The support rod 11 has an operating end and a monitoring end, and has an operating channel 111 and a wire harness channel 112 along its axial direction. The two channels are independent of each other. The camera device 12 is installed at the port of the wire harness channel 112 located at the monitoring end. The spray gun 2 and biopsy forceps 3 are movably inserted into the operating channel 111.

[0040] Specifically, it also includes a disposable inspection film. The disposable inspection film is elastically wrapped around the outer surface of the monitoring unit 1, and a hole is reserved at the port of the operation channel 111 located at the monitoring end. Thus, the disposable inspection film can prevent human tissue from contaminating the outer surface of the monitoring unit 1.

[0041] See appendix Figure 4 , 5The monitoring unit 1 also includes a water-filled ring 13 and a peristaltic pump. A mounting groove 113 is formed on the outer wall of the support rod 11 at the operating end. The water-filled ring 13 is installed within the mounting groove 113. A water passage hole 114 communicating with the wire harness channel 112 is formed on the bottom surface of the mounting groove 113. The water passage 10 between the peristaltic pump interface and the water-filled ring 13 is connected through the wire harness channel 112 and the water passage hole 114. Therefore, during biopsy collection from a patient, pressure can be applied to the water-filled ring 13 by the peristaltic pump, causing the water-filled ring 13 to expand outwards. This fixes the relative position of the support rod 11 and the vaginal wall, preventing the support rod 11 from slipping during biopsy collection and affecting the field of vision and operation.

[0042] To further optimize the above technical solution, the monitoring unit 1 also includes heating wires 15. Multiple heating wire mounting holes 115 are spaced apart along the circumference of the operating end, and the multiple heating wires 15 are respectively installed within the multiple heating wire mounting holes 115. Thus, the outer wall surface of the support rod 11 can be heated by the heating wires, avoiding patient discomfort during operation due to excessively low temperature of the support rod 11.

[0043] See appendix Figure 6 The support rod 11 is elongated with an elliptical cross-section. The monitoring end has a smooth surface and a stepped end corresponding to the major axis of the ellipse. The lens of the camera device 12 and the wiring harness channel 112 are smoothly transitioned at the port of the monitoring end. The port of the operation channel 111 at the monitoring end is concave, and the port of the wiring harness channel 112 at the monitoring end is convex. Therefore, the cross-sectional design and smooth transition of the end allow for better adaptation to the human body structure, reducing pressure and friction on the vaginal wall, minimizing patient discomfort, and improving the ease of insertion and operation of the device.

[0044] See appendix Figure 7 , 8 The monitoring unit 1 also includes an end cap 16. The inner side of the end cap 16 has a wire harness clearance groove 161 and is detachably connected to the operating end of the support rod 11. The outer wall of the end cap 16 has an operating hole 162 coaxially arranged with the operating channel 111. A connecting pipe 163 is connected to the outer wall of the end cap 16 above the operating hole 162. Thus, the end cap 16 covers the port of the operating end of the support rod 11, and the wire harness clearance groove 161 provides bending space for the wire harness converging at the operating end of the wire harness channel 112, allowing it to maintain a certain bending angle when leading out from the connecting pipe 163 to connect with external equipment, avoiding problems such as poor water flow caused by excessively small bending radii.

[0045] See appendix Figure 7 , 9The spray gun 2 includes a gun body 21, a gun handle 22, a control key 23, and a gun rod 24. The gun body 21 contains dye or medicine. A medicine filling hole 211 is opened at the top of the gun body 21. The gun handle 22 is fastened to the bottom of the gun body 21. The control key 23 is installed on the side of the gun body 21. The gun rod 24 is installed at the front end of the gun body 21. The end of the gun rod 24 away from the gun body 21 has a nozzle. The nozzle and the gun rod 24 can be moved from the operating end into the operating channel 111.

[0046] In some embodiments, a limiting block 221 is fastened to the outer wall surface of the end of the gun barrel 24 connected to the gun body 21, and a limiting groove 164 is provided on the side wall surface of the operating hole 162, which is correspondingly arranged and can be adapted to abut against the limiting block 221. Thus, the design of the limiting block 221 and the limiting groove 164 can effectively fix the spray gun 2, prevent it from shifting or falling off during operation, and ensure the stability and safety of the dyeing operation.

[0047] Specifically, there are two limiting blocks 221, which are arranged symmetrically about the axis of the gun handle 22 in the radial direction of the gun handle 22. There are two limiting grooves 164, which are arranged corresponding to the two limiting blocks 221 respectively, so as to improve the stability of the spray gun 2 in the dyeing process.

[0048] See appendix Figure 4 , 10 The biopsy forceps 3 includes a forceps body 31, a movable handle 32, and a live body collection part 33. The first end of the forceps body 31 has a fixed handle 311, and the second end has a long support arm 312. The first end of the movable handle 32 is rotatably connected to the first end of the forceps body 31. One end of the live body collection part 33 is rotatably connected to the end of the long support arm 312 away from the fixed handle 311 and is drively connected to the first end of the movable handle 32. The live body collection part 33 and the forceps body 31 can extend from the operating end into the operating channel 111.

[0049] In some specific embodiments, the monitoring unit 1 further includes a temperature probe mounted on the side wall of the support rod 11. Thus, the temperature probe can monitor the temperature of the support rod 11 in real time, preventing harm to the patient due to excessively high or low temperatures, while also providing data support for temperature adjustment of the heating wire 15.

[0050] In some other embodiments, the monitoring unit 1 also includes a controller, which is electrically connected to the control modules of the temperature probe, the heating wire 15, and the peristaltic pump. Thus, the integration of the controller enables unified control of the temperature probe, the heating wire 15, and the peristaltic pump, improving the intelligence level of the equipment, reducing human error, and enhancing the safety and efficiency of the surgery.

[0051] See appendix Figure 11It also includes a remote control 4 and a display 5. The remote control 4, the display 5 and the camera device 12 are all electrically connected to the controller. The remote control 4 is used to adjust the camera area of ​​the camera device 12, and the display 5 is used to play the images monitored by the camera device 12 in real time.

[0052] Specifically, the remote control 4 can flexibly control the viewing direction of the camera device 12.

[0053] The specific principle and usage of the dual-cavity vaginal examination instrument provided in this embodiment are as follows:

[0054] 1. Wrap the outer surface of monitoring unit 1 with a disposable inspection sleeve;

[0055] 2. Apply lubricant evenly to the outer surface of the disposable inspection diaphragm;

[0056] 3. The control module of the controller controls the heating wire 15 to heat the outer wall surface of the support rod 11;

[0057] 4. After the outer wall of the support rod 11 is heated to the specified temperature, the monitoring end of the monitoring unit 1 is inserted into the patient's vagina with the monitoring end facing forward, and the lesion location is observed through the camera device 12;

[0058] 5. Determine whether to perform a biopsy based on the image fed back by the camera device 12. If a biopsy is required, continue with the following steps. If not, skip steps 6, 7, and 8 and the operation ends.

[0059] 6. The control module of the peristaltic pump is controlled by the controller to pressurize the water bladder ring 13, and then maintains a constant pressure after the pressure is increased to the specified pressure;

[0060] 7. Insert the limiting block 221 of the spray gun 2 into the limiting groove 164, press the control key 23, and stain the lesion tissue of the patient;

[0061] 8. The biopsy forceps 3's biopsy collection section 33 is brought to the patient's lesion location through the operation channel 111 to collect the lesion tissue;

[0062] 9. After the data collection is completed, the water bladder ring 13 is depressurized by the control module of the peristaltic pump controlled by the controller, and then the monitoring unit 1 is taken out.

[0063] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
