Detailed Implementation
[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0026] See Figures 1 to 8 As shown, a disposable multi-specification uterine cup includes a uterine lifter 1, a multi-stage uterine lifter 2, a uterine lifter rod 3, a myoma drill 4, and a guide rod 5. The uterine lifter 1 has a first operating screw 11 on its side and a first limiting insertion hole inside. The multi-stage uterine lifter 2 is installed at the end of the uterine lifter 1 away from the first operating screw 11. The uterine lifter rod 3 is installed in the first limiting insertion hole and has a second limiting insertion hole inside. The uterine lifter rod 3 has a second operating screw 31 on its side. The myoma drill 4 is installed at the end of the uterine lifter rod 3 away from the second operating screw 31. The guide rod 5 is installed in the second limiting insertion hole. The multi-stage uterine lifter 2 includes an expansion adjustment seat 21 installed on the uterine lifter 1. The contact end of the expansion adjustment seat 21 can be expanded and adjusted, and an expansion adjustment ring 22 is installed inside the expansion adjustment seat 21.
[0027] The uterine lifter 1, multi-stage uterine lifter cup 2, uterine lifter bar 3, fibroid drill 4, and guide bar 5 are all made of plastic and rubber, ensuring low manufacturing costs and ease of processing. All components are packaged in disposable sterile bags after production to ensure sterility and reduce the risk of cross-infection.
[0028] Medical staff open the sterilization bag and select a suitable dilation adjustment ring 22 based on the patient's uterine size. The selected dilation adjustment ring 22 is then snapped into the dilation adjustment seat 21, expanding the contact end of the seat 21 to the appropriate size. The multi-stage uterine lifting cup 2 is installed onto the uterine lifting frame 1, and the fibroid drill 4 is installed onto the uterine lifting rod 3. The uterine lifting rod 3 is inserted into the first limiting insertion hole of the uterine lifting frame 1 and locked in position using the first operating screw 11. The guide rod 5 is passed through the second limiting insertion hole of the uterine lifting rod 3 and positioned and fixed using the second operating screw 31. After assembly, the patient can proceed with the surgical procedure.
[0029] After the surgery, medical staff can directly discard the device as a single-use item, eliminating the need for cumbersome sterilization procedures, effectively improving surgical efficiency and reducing the risk of cross-infection. Through its ingenious structural design and material selection, this device achieves multi-size adaptability and the convenience of single-use, greatly improving the safety and efficiency of surgery.
[0030] See Figure 2 and Figure 3 As shown, the inner wall of the expansion adjustment seat 21 is provided with a rotating snap-fit groove 211, the top of the expansion adjustment seat 21 is provided with multiple expansion brackets 212, the inner wall of each expansion bracket 212 is provided with an expansion snap-fit groove 213, and the outer side of the expansion bracket 212 is fitted with a first elastic abutment sleeve 214.
[0031] The rotating locking groove 211 is used to lock and fix the position of the expansion adjustment ring 22, and the expansion locking groove 213 is used to limit the adjustment area of the expansion adjustment ring 22. Different shaft diameters of the adjustment area of the expansion adjustment ring 22 will change the expansion range of the expansion support 212. By using expansion adjustment rings 22 of different sizes, the size of the expansion support 212 can be adjusted in multiple stages. When the expansion support 212 is adjusted, the first elastic abutment sleeve 214 will expand and adjust accordingly, so that the first elastic abutment sleeve 214 can adapt to abut against different uterine sizes. The design of the first elastic abutment sleeve 214 ensures that the multi-stage uterine cup 2 can fit tightly and adaptably against uterine sizes, improving the adaptability and comfort of use.
[0032] See Figure 2 and Figure 3 As shown, the bottom of the expansion adjustment ring 22 is provided with a snap-fit fixing ring 221, and the outer side of the snap-fit fixing ring 221 is provided with multiple limiting buckles 222. The limiting buckles 222 match the rotating snap-fit groove 211. The top of the expansion adjustment ring 22 is provided with an expansion support ring 223, and the outer ring of the expansion support ring 223 matches the expansion snap-fit groove 213.
[0033] When it is necessary to adjust the expansion range of the dilation stent 212, the bottom of the dilation adjustment ring 22 is provided with a locking ring 221, and the outer side of the locking ring 221 is provided with multiple limiting buckles 222. Align the bottom of the dilation adjustment ring 22 with the rotating locking groove 211 of the dilation adjustment seat 21, so that the limiting buckles 222 are inserted into the rotating locking groove 211. Rotate the dilation adjustment ring 22 to limit and fix the limiting buckles 222 in the rotating locking groove 211, thereby ensuring that the dilation adjustment ring 22 is securely installed on the dilation adjustment seat 21. The top of the dilation adjustment ring 22 is provided with an expansion support ring 223, the outer ring of which matches the expansion locking groove 213 of the dilation stent 212. A suitable dilation adjustment ring 22 is selected according to the size of the patient's uterus. Different dilation adjustment rings 22 have different shaft diameters of their expansion support rings 223, thus allowing adjustment of the expansion range of the dilation stent 212. The expansion support ring 223 is mated against the expansion retaining groove 213. The change in the shaft diameter of the expansion support ring 223 causes the expansion bracket 212 to expand or contract accordingly. As the expansion bracket 212 expands or contracts, the first elastic abutment sleeve 214 will also expand or contract adaptively.
[0034] By preparing multiple expansion adjustment rings 22 with different shaft diameters, multi-level adjustment of the multi-stage uterine cup 2 can be achieved, thereby adapting to the size of the uterus of different patients. This multi-stage adjustment design effectively saves the number of uterine cups, reduces medical costs, and improves the utilization efficiency of medical resources.
[0035] See Figure 4 As shown, the bottom of the multi-stage lifting cup 2 is provided with a multi-stage adjustment seat 23, and the top of the multi-stage adjustment seat 23 is fitted with a second elastic abutment sleeve 24.
[0036] The multi-level adjustable seat 23 can adjust the second elastic abutment sleeve 24 in multiple levels, so that the second elastic abutment sleeve 24 can precisely switch between different diameters, ensuring that the second elastic abutment sleeve 24 can abut against uteruses of different sizes.
[0037] See Figures 4 to 7 As shown, the multi-stage adjustment seat 23 has multiple limiting mounting grooves 231 inside, and multiple limiting teeth 237 on the inner wall of the multi-stage adjustment seat 23. A limiting adjustment plate 233 is also installed on the multi-stage adjustment seat 23. The outer wall of the limiting adjustment plate 233 is covered with limiting tooth grooves 2331. An inclined adjustment rail 234 is also installed on the limiting adjustment plate 233. The multi-stage adjustment seat 23 also includes multiple vertical connecting columns 232 distributed inside the limiting mounting grooves 231. One end of the vertical connecting column 232 away from the limiting mounting groove 231 extends upward through the inclined adjustment rail 234. An expansion adjustment strip 236 is installed at the extended end of the vertical connecting column 232. The expansion adjustment strip 236 is connected to the second elastic abutment sleeve 24. A push spring 235 is installed between the limiting adjustment plate 233 and the multi-stage adjustment seat 23.
[0038] The multi-stage adjustment seat 23 has multiple limiting mounting slots 231 inside, which are used to limit and guide the vertical connecting column 232. The inner wall of the multi-stage adjustment seat 23 is equipped with multiple limiting teeth 237, which are used to cooperate with the limiting tooth grooves 2331 of the limiting adjustment plate 233 to achieve positioning after rotation. The tilt adjustment rail 234 of the limiting adjustment plate 233 is used to guide the sliding of the vertical connecting column 232, and the expansion adjustment bar 236 is connected to the second elastic abutment sleeve 24 to transmit the adjustment action. The push spring 235 is installed between the limiting adjustment plate 233 and the multi-stage adjustment seat 23 to provide the restoring force.
[0039] When the diameter of the second elastic abutment sleeve 24 needs to be adjusted, the medical staff first presses the limiting adjustment disc 233. During the pressing process, the push spring 235 is compressed, and at the same time, the limiting tooth groove 2331 of the limiting adjustment disc 233 disengages from the limiting locking tooth 237 of the multi-stage adjustment seat 23, allowing the limiting adjustment disc 233 to rotate freely. The medical staff then rotates the limiting adjustment disc 233, which is transmitted to the vertical connecting column 232 through the inclined adjustment rail 234, causing the vertical connecting column 232 to slide within the limiting mounting groove 231. The sliding of the vertical connecting column 232 drives the expansion adjustment strip 236 to move, thereby pulling or pushing the second elastic abutment sleeve 24 to adjust its diameter. When the second elastic abutment sleeve 24 is adjusted to the required size, the medical staff stops pressing the limiting adjustment disc 233. After the push spring 235 loses its external force, it pushes the limiting adjustment plate 233 upward to reset, causing the limiting tooth groove 2331 to re-engage with the limiting retaining tooth 237, thus locking the position of the limiting adjustment plate 233. The positioning of the limiting adjustment plate 233 ensures the stability of the second elastic abutment sleeve 24 and guarantees the accuracy of adjustment. This device can accurately adjust the diameter of the two elastic abutment sleeves without requiring too many adjustment parts, thereby adapting to uteruses of different sizes and improving the precision and safety of the surgery.
[0040] See Figure 8 As shown, the multi-stage uterine cup 2 includes a fixed connecting seat 25, on which a flexible sleeve 251 is installed, and a flexible flange 252 is provided on the outer side of the flexible sleeve 251.
[0041] First, the fixed connecting seat 25 of the multi-stage uterine cup 2 serves as the supporting foundation of the entire structure. Because it is made of a rigid material, it can stably maintain and support the shape of the flexible sleeve 251, ensuring that no accidental deformation occurs during use. Second, the flexible sleeve 251, as the part that directly contacts the uterus, has a certain degree of expandability. This expandability allows the flexible sleeve 251 to be appropriately adjusted according to the shape and size of the uterus of different patients, thereby achieving better contact adaptability. During the operation, the doctor can manipulate the flexible sleeve 251 to fit tightly against the uterus, ensuring the precision and safety of the operation. The flexible flange 252 on the outer side of the flexible sleeve 251 further enhances its contact effect with the uterus. The flexible flange 252 not only increases the contact area and improves stability, but also ensures a close fit to the uterine wall through its soft material and conforming design, reducing the risk of slippage or displacement during the operation. This structure is simple and easy to manufacture.
[0042] Specific working principle:
[0043] The uterine lifter 1, multi-stage uterine lifter cup 2, uterine lifter bar 3, fibroid drill 4, and guide bar 5 are all made of plastic and rubber, ensuring low manufacturing costs and ease of processing. All components are packaged in disposable sterile bags after production to ensure sterility and reduce the risk of cross-infection.
[0044] Medical staff open the sterilization bag and select a suitable dilation adjustment ring 22 based on the patient's uterine size. The selected dilation adjustment ring 22 is then snapped into the dilation adjustment seat 21, expanding the contact end of the seat 21 to the appropriate size. The multi-stage uterine lifting cup 2 is installed onto the uterine lifting frame 1, and the fibroid drill 4 is installed onto the uterine lifting rod 3. The uterine lifting rod 3 is inserted into the first limiting insertion hole of the uterine lifting frame 1 and locked in position using the first operating screw 11. The guide rod 5 is passed through the second limiting insertion hole of the uterine lifting rod 3 and positioned and fixed using the second operating screw 31. After assembly, the patient can proceed with the surgical procedure.
[0045] After the surgery, medical staff can directly discard the device as a single-use item, eliminating the need for cumbersome sterilization procedures, effectively improving surgical efficiency and reducing the risk of cross-infection. Through its ingenious structural design and material selection, this device achieves multi-size adaptability and the convenience of single-use, greatly improving the safety and efficiency of surgery.
