[0001] This utility model belongs to the field of medical auxiliary device technology, specifically relating to a device for assisting in the separation of cervical adhesions. Background Technology

[0002] Currently, cervical canal adhesions are frequently encountered in clinical practice due to inflammation and other causes (excluding malignant tumors), such as adhesions after partial cervicectomy or in elderly patients with severe cervical atrophy due to prolonged menopause. During treatment and surgery, severe adhesions at the internal and external cervical os make it difficult for probes to penetrate the cervical canal and reach the uterine cavity, thus hindering subsequent treatment and surgery. Currently, probes or dissecting forceps are widely used in clinical practice to separate cervical adhesions. However, for patients with adhesions at the external cervical os, existing probes and dissecting forceps are too thick and inconvenient for separation.

[0003] Therefore, this utility model proposes a novel device for assisting in the separation of cervical adhesions. Utility Model Content

It expands the vagina using an upper hollow dilator with an ultrasound probe and a lower hollow dilator with an ultrasound probe to guide the probe further in. The probe is then pushed in further to position it at the cervical os. The probe can then separate the adhesions at the cervical os, thus achieving the separation of cervical adhesions. This method is simple and convenient, and the tip of the probe is thinner than existing ones, allowing it to pass through the cervical os more effectively.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for assisting in the separation of cervical adhesions, comprising an upper hollow dilator, a lower hollow dilator, and a probe.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] Please see Figure 1-7 This utility model provides the following technical solution: a device for assisting in the separation of cervical adhesions, comprising an upper hollow dilator 1, a lower hollow dilator 13, and a probe 9. An ultrasound probe 2 is fixedly connected to the upper front end of the upper hollow dilator 1. An end plate 3 is integrally formed at the bottom rear end of the upper hollow dilator 1. The lower hollow dilator 13 is located at the bottom end of the upper hollow dilator 1. Both the upper hollow dilator 1 and the lower hollow dilator 13 are tapered structures. An ultrasound probe 2 14 is fixedly connected to the bottom front end of the lower hollow dilator 13. A hollow handle 15 is integrally formed at the bottom rear end of the lower hollow dilator 13. The end plate 3 is slidably connected to the lower hollow dilator 13. The ultrasound probe is used for scanning and imaging of the vagina and cervix, employing a commonly used device for existing vaginal examinations. Ultrasound imaging is a conventional technique and will not be elaborated upon here.

[0030] In this embodiment, when using this invention, the vagina can be dilated using an upper hollow dilator 1 with an ultrasound probe 12 and a lower hollow dilator 13 with an ultrasound probe 24 to guide the probe 9 further in. The conical structure of the upper hollow dilator 1 and the lower hollow dilator 13 facilitates entry into the vagina for dilation. After the upper hollow dilator 1 and the lower hollow dilator 13 are inserted into the vagina, they are opened to dilate the vagina. Then, the probe 9 is pushed in so that it is positioned at the cervix. The probe 9 can separate the adhesions at the cervix, thus achieving the separation of cervical adhesions. This method is simple and convenient. The tip of the probe 9 is thinner than existing probes, allowing it to pass through the cervix more easily.

[0031] Furthermore, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, a hollow large ball sleeve 4 is fixedly connected to the upper end of the end plate 3. A hollow small ball sleeve 5 is rotatably connected inside the hollow large ball sleeve 4. A guide tube 6 is fixedly connected to the rear end of the hollow small ball sleeve 5. A threaded tube 7 is integrally formed on the left side of the rear end of the guide tube 6, and a locking bolt 8 is screwed into the inside of the threaded tube 7. A probe 9 is movably connected inside the guide tube 6. The probe 9 can move forward and backward along the guide tube 6. An end handle 10 is integrally formed at the rear end of the probe 9. The diameter of the probe 9 decreases from back to front. The diameter of the front end of the probe 9 is 1 mm, and the diameter of the rear end of the probe 9 is 3 mm. The hollow large ball sleeve 4 and the hollow small ball sleeve 5 are both through-holes to allow the probe 9 to pass forward. The threaded tube 7 communicates with the inside of the guide tube 6 so that the locking bolt 8 can be screwed into the guide tube 6 to lock and limit the probe 9.

[0032] It can be seen that during the use of this utility model, the locking bolt 8 is first unscrewed outward so that it does not block the probe 9. At this time, the probe 9 can be inserted into the cervix through the open upper hollow expansion rod 1 and lower hollow expansion rod 13 via the end handle 10. Then, the locking bolt 8 is screwed inward to block the probe 9, locking and limiting the probe 9 in the guide tube 6, which can prevent the probe 9 from sliding out of the guide tube 6. At the same time, based on the cooperation of the hollow large ball sleeve 4 and the hollow small ball sleeve 5, a "universal joint" structure is formed between the hollow large ball sleeve 4 and the hollow small ball sleeve 5. Therefore, by swinging the end handle 9, the front end of the probe 9 can swing flexibly to separate the cervical adhesions. The structure is simple and the operation is convenient.

[0033] Furthermore, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the left side of the end plate 3 has several limiting recesses 11, and the rear end of the end plate 3 is integrally formed with several anti-slip protrusions 12, which are linearly and equidistantly distributed. The limiting recesses 11 are also linearly and equidistantly distributed. Springs 16 are fixedly connected to both sides of the bottom of the hollow handle 15, and the bottom of the end plate 3 is fixedly connected to the upper end of the springs 16. A positioning through hole 17 is provided on the upper left side of the hollow handle 15. Both the positioning through hole 17 and the limiting recesses 11 are rectangular structures with the same inner diameter. A trapezoidal limiting block 18 is movably connected inside the positioning through hole 17, and the right end of the trapezoidal limiting block 18 engages with the limiting recess 11. A pull button 19 is integrally formed on the left end of the trapezoidal limiting block 18. A spring 20 is fixedly connected to the right end of the button 19 and the left side of the hollow handle 15. The front end of the hollow handle 15 is integrally formed with an anti-slip sleeve 21, which has a "U" shaped structure. The anti-slip protrusion 12 allows the end plate 3 to be pushed upward relative to the hollow handle 15. The spring 16 allows the end plate 3 to automatically spring back and reset after being limited. The trapezoidal limiting block 18 is designed so that the end plate 3 will not be blocked by obstacles when it moves upward relative to the hollow handle 15. It can also automatically engage with the limiting recess 11 by elastically extending and retracting the spring 20. The pull button 19 allows the trapezoidal limiting block 18 to be pulled out to release the limited state of the end plate 3. The anti-slip sleeve 21 is worn over the hand to effectively prevent the device from slipping off the hand, making the device easier to hold and use.

[0034] In this embodiment, during use, the end plate 3 can achieve self-locking and limiting by the cooperation of the end plate 3, the limiting recess 11, the hollow handle 15, the first spring 16, the positioning through hole 17, the trapezoidal limiting block 18, the pull button 19 and the second spring 20, so as to achieve self-fixation of the upper hollow expansion rod 1 and the lower hollow expansion rod 13 after they are opened. The operation is simple, labor-saving and convenient, so as to facilitate the opening and closing of the upper hollow expansion rod 1 and the lower hollow expansion rod 13.

[0035] The usage process and working principle of this utility model are as follows: In use, connect the ultrasonic probe 12 and ultrasonic probe 24 to an external ultrasonic display device. Then, hold the hollow handle 15 and insert your fingers through the anti-slip sleeve 21. Next, insert the upper hollow expansion rod 1 and the lower hollow expansion rod 13 into the vagina. Immediately afterwards, push the end plate 3 upwards through the anti-slip protrusion 12. During this process, the end plate 3 can move upwards relative to the hollow handle 15, causing the spring 16 to stretch. Furthermore, through the elastic extension and contraction of the spring 20, the trapezoidal limiting block 18 in the positioning through hole 17 can automatically and elastically engage with the limiting recess 1. In step 1, the end plate 3 is self-locking and limiting, thereby achieving self-fixation of the upper hollow expansion rod 1 and the lower hollow expansion rod 13 after opening. Then, the external locking bolt 8 is rotated to release the limiting and fixing state of the probe 9. Then, the probe 9 is pushed further by the end handle 10, so that the probe 9 is located at the cervical opening and the internal locking bolt 8 is rotated to fix the probe 9. Then, the probe 9 can separate the cervical adhesions to achieve the separation of cervical adhesions. During this process, the hollow small ball sleeve 5 can rotate in the hollow large ball sleeve 4, which can realize the flexible swing of the probe 9 to separate the adhesions of the cervix.

[0036] After use, turn the locking bolt 8 outward, then pull the probe 9 backward so that the front part of the probe 9 is retracted inside the upper hollow expansion rod 1 and the lower hollow expansion rod 13. Then turn the locking bolt 8 inward to limit and fix the probe 9 to prevent it from falling out. After that, pull the trapezoidal limit block 18 and the second spring 20 outward through the pull button 19 so that the trapezoidal limit block 18 can be dislodged from the limit recess 11 to release the limit fixation state of the end plate 3. At the same time, under the elastic force of the first spring 16, the end plate 3 can automatically reset and retract relative to the hollow handle 15 to close the upper hollow expansion rod 1 and the lower hollow expansion rod 13.

[0037] Furthermore, any content not described in detail in this embodiment falls within the scope of existing technology and common knowledge.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
