Description

Technical Field

[0001] This invention relates to the field of medical supplies technology, specifically to a disposable vaginal stump positioning tag for use after radical hysterectomy for uterine tumors. Background Technology

[0002] Radical hysterectomy is a classic radical surgical procedure for malignant uterine tumors. Its core goal is to completely remove the diseased uterus, potentially invaded adjacent tissues, and lymph nodes in potential metastatic areas to maximize the clearance of tumor lesions, thereby significantly reducing the risk of postoperative recurrence. This surgery is one of the main treatment methods for malignant uterine tumors such as cervical cancer and endometrial cancer.

[0003] Postoperative radiotherapy is often necessary to eliminate any remaining microscopic lesions in the surgical area and further reduce the risk of local recurrence. During radiotherapy, to ensure precise coverage of the vaginal stump (the sutured end of the vaginal roof after surgical resection) while avoiding damage to surrounding normal tissues (such as the rectum and bladder), clear imaging marking of the vaginal stump is required. Currently, the commonly used clinical method involves taking a sterile cotton swab, soaking it in an appropriate amount of iohexol contrast agent, covering the swab with a sterile condom, and then slowly inserting it into the patient's vagina, ensuring the tip of the iohexol-soaked swab rests against the vaginal stump, thus marking the lower boundary of the radiotherapy target area. However, the existing clinical procedures described above require medical staff to prepare sterile cotton swabs, iohexol, and sterile condoms in advance for on-site preparation. After the prepared markers are inserted into the vagina, there is a risk that iohexol may leak out, causing the contrast area to become blurred or shift in position, which in turn makes it difficult to delineate the radiotherapy target area. If the marking is inaccurate due to the displacement of the contrast agent, the irradiation range may be excessively extended into normal tissues, increasing the risk of radiation damage to surrounding organs. Therefore, improvements are urgently needed.

[0004] Therefore, how to design a quick, convenient, and precise disposable vaginal stump positioning tag for use after radical hysterectomy for uterine tumors is a technical problem that has not yet been solved in the existing technology. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the technical defects of the prior art in which the markers made on site, after being inserted into the vagina, cause the imaging area to become blurred or the position to shift, which affects the accuracy of the radiotherapy target area delineation and increases the risk of radiation damage to surrounding tissues. Thus, the present invention provides a quick, convenient and accurate disposable vaginal stump positioning tag for use after radical hysterectomy for uterine tumors.

[0006] Therefore, the present invention provides a disposable vaginal stump positioning tag for use after radical hysterectomy for uterine tumors, comprising: The positioning rod has a closed cavity at its front end, and the closed cavity contains a positioning marker.

Preferably, the receiving cavity is filled with lubricating fluid.

[0012] As a preferred embodiment, an annular sealing plane is formed on the inner top wall of the mounting sleeve, and at least one first annular sealing protrusion is formed on the outer wall of the sterile silicone sleeve opposite to the annular sealing plane; after the outer flange is installed into the mounting sleeve, the first annular sealing protrusion is pressed and sealed against the annular sealing plane. And / or, An annular sealing side is formed on the inner wall of the mounting sleeve, and at least one second annular sealing protrusion is formed on the outer wall of the sterile silicone sleeve opposite to the annular sealing side; after the outer flange is installed into the mounting sleeve, the second annular sealing protrusion and the annular sealing side are pressed and sealed in contact.

[0013] As a preferred embodiment, it further includes a detachable fixing ring sleeve, which is tightly installed on the outer wall of the mounting sleeve on which the outer flange is mounted. The ring sleeve includes a first horizontal annular surface that abuts against the outside of the top surface of the mounting sleeve, a second horizontal annular surface that abuts against the bottom of the sterile silicone sleeve, and a vertical annular surface that connects the first horizontal annular surface and the second horizontal annular surface and abuts against the outer side of the mounting sleeve, thereby sealing and fixing the mounting sleeve to the outer flange covering the sterile silicone sleeve.

[0034] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0035] This embodiment provides a disposable vaginal stump positioning tag for use after radical hysterectomy for uterine tumors, such as... Figure 1-2 As shown in Figures 6-7, the device includes: a positioning rod 1, a sterile silicone sleeve 3, and a light-shielding outer shell 4; wherein, the positioning rod 1 has a closed cavity 21 at its head end, and the closed cavity 21 contains a positioning marker; the sterile silicone sleeve 3 is made of transparent material and is disposed on the outer wall of the positioning rod 1; the light-shielding outer shell 4 is detachably fitted and installed on the outside of the sterile silicone sleeve 3.

[0036] When the patient receives radiotherapy after surgery, the light-shielding outer shell 4 is removed, and the positioning rod 1 is inserted into the patient's body, with the tip of the positioning marker 2 placed against the vaginal stump. This clearly marks the lower boundary of the radiotherapy target area on the image. During radiotherapy, when the irradiation range covers the position of the marker, the downward extension of irradiation is stopped, thereby effectively avoiding excessive downward extension of the irradiation range and reducing the risk of radiation damage to surrounding normal organs such as the rectum and bladder. Compared with on-site marker fabrication, this embodiment uses a disposable vaginal stump positioning tag after radical hysterectomy for uterine tumors, which can effectively avoid the problems of outflow and displacement of the positioning marker 2, ensuring accurate marking of the vaginal stump and guaranteeing the accuracy of the radiotherapy target area delineation. When using it, only the light-shielding outer shell 4 needs to be removed for direct insertion, making the operation simple and quick.

[0037] In this embodiment, the light-proof outer shell 4 is made of an opaque material.

[0038] like Figure 3-5 As shown, the positioning rod 1 includes a rod body 16 and a top cover 12; the rod body 16 has a first cavity 11 formed at its first end, and the top cover 12 is made of transparent material and has a second cavity 13 formed in the middle; the top cover 12 is installed at the first end of the rod body 16 to form the positioning rod 1, and the first cavity 11 and the second cavity 13 are combined to form the closed cavity 21.

[0039] An annular snap-fit ​​protrusion 14 is formed on the outer wall of the opening end of the first cavity 11, and an annular snap-fit ​​groove 15 is formed on the inner wall of the opening end of the second cavity 13; the annular snap-fit ​​protrusion 14 and the annular snap-fit ​​groove 15 are matched and snapped together, so that the top cover 12 is installed at the head end of the rod 16.

[0040] The positioning marker 2 is an iodinated cotton ball.

[0041] The sterile silicone sleeve 3 is thermoplastically formed on the outer wall of the positioning rod 1, forming a seamless and integrated sealing effect with the outer wall of the positioning rod 1, which can ensure that iohexol cannot leak out.

[0042] like Figure 6 , 8As shown, the positioning rod 1 has an outer flange 43 formed on its outer wall near the tail end, and the sterile silicone sleeve 3 is wrapped around the outer flange 43. The light-shielding shell 4 has a receiving cavity 41 with a tail end opening. A mounting sleeve 42 is formed around the tail end opening. The positioning rod 1 is installed into the receiving cavity 41 through the tail end opening, and the outer flange 43 is installed into the mounting sleeve 42. The sterile silicone sleeve 3, which is fitted outside the outer flange 43, is pressed and fitted against the inner wall of the mounting sleeve 42 to achieve a sealed installation. The receiving cavity 41 is filled with lubricating fluid. Before removing the light-shielding shell 4, the light-shielding shell 4 can be shaken slightly to allow the lubricating fluid in the receiving cavity 41 to adhere evenly to the surface of the sterile silicone sleeve 3. When the positioning rod 1 is inserted, the lubricating fluid on the sterile silicone sleeve 3 can effectively reduce friction, making the insertion process smoother and easier.

[0043] like Figure 9 As shown, an annular sealing plane 44 is formed on the inner top wall of the mounting sleeve 42, and at least one first annular sealing protrusion 45 is formed on the outer wall of the sterile silicone sleeve 3 opposite to the annular sealing plane 44. After the outer flange 43 is installed into the mounting sleeve 42, the first annular sealing protrusion 45 is pressed and sealed against the annular sealing plane 44. An annular sealing side 47 is formed on the inner side wall of the mounting sleeve 42, and at least one second annular sealing protrusion 46 is formed on the outer wall of the sterile silicone sleeve 3 opposite to the annular sealing side 47. After the outer flange 43 is installed into the mounting sleeve 42, the second annular sealing protrusion 46 is pressed and sealed against the annular sealing side 47. The sealing protrusions are used to seal the receiving cavity 41 to prevent lubricant leakage.

[0044] like Figure 10-11 As shown, it also includes a detachable fixing ring 5, which is tightly installed on the outer wall of the mounting sleeve 42 on which the outer flange 43 is installed. The detachable fixing ring 5 includes a first horizontal annular surface 53 that abuts against the outside of the top surface of the mounting sleeve 42, a second horizontal annular surface 54 that abuts against the bottom of the sterile silicone sleeve 3, and a vertical annular surface 55 that connects the first horizontal annular surface 53 and the second horizontal annular surface 54 and abuts against the outer side of the mounting sleeve 42, thereby sealing and fixing the mounting sleeve 42 and the outer flange 43 covering the sterile silicone sleeve 3 together.

[0045] The detachable fixing ring 5 is made of plastic. An annular easy-tear strip 51 is formed on the vertical annular surface 55 of the detachable fixing ring 5. A tear-off head 52 is provided at the free end of the annular easy-tear strip 51. The tear-off head 52 is suitable for gripping and easily applies pulling force to tear off the annular easy-tear strip 51, thereby removing the detachable fixing ring 5. When it is necessary to disassemble the light-shielding outer shell 4, hold the tear-off head 52 and apply pulling force along the direction of the annular easy-tear strip 51 to completely tear off the annular easy-tear strip 51. At this time, the detachable fixing ring 5 can be easily removed, thus achieving the smooth disassembly of the light-shielding outer shell 4.

[0046] A gripping rod 6 is formed below the outer flange 43 of the positioning rod 1. Medical personnel can use the gripping rod 6 to operate the positioning rod 1 when removing the light-proof outer shell 4 or inserting it.

[0047] In this embodiment, a disposable vaginal stump positioning tag is used after radical hysterectomy for uterine tumors. The method of use is as follows: When using it, the medical staff first gently shakes the light-proof shell 4 so that the lubricant in the receiving cavity 41 is evenly attached to the surface of the sterile silicone sleeve 3; then, holding the holding rod 6 with one hand and the tearing head 52 with the other hand, the staff applies a pulling force along the direction of the annular easy-tear strip 51 to completely tear off the annular easy-tear strip 51. At this time, the detachable fixing ring 5 can be easily removed, and then the light-proof shell 4 can be disassembled smoothly; after the light-proof shell 4 is disassembled, the positioning rod 1 is inserted into the patient's body so that the tip of the cotton ball with iodine is placed against the vaginal stump, so as to clearly mark the lower boundary of the radiotherapy target area on the image.

[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
