Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a supported vaginal wall biopsy forceps that can help medical staff obtain a better field of vision, facilitate single-person operation, and make vaginal lesion examination more comprehensive, faster, and safer. Background Technology

[0002] The vaginal wall can harbor various lesions, with vaginal intraepithelial neoplasia (VIN) being the most common and a precancerous lesion of vaginal epithelial carcinoma. If left undetected or untreated, it can develop into invasive vaginal carcinoma and is closely related to HPV infection. Even in patients who have undergone hysterectomy and cervical removal, the vaginal stump and remaining vaginal wall can still develop VIN or invasive vaginal carcinoma due to HPV infection. Colposcopy and biopsy are essential to determine the location, extent, and nature of the lesion. However, during medical procedures, this is usually performed by a single physician. Because the vaginal space is small, especially the vaginal wall in the cervical fornix and the vaginal wall at the corner of the vaginal stump after a total hysterectomy, these areas are extremely difficult to expose. Lesions in these areas may be missed, but it is difficult for the surgeon to hold other instruments to expose these parts of the vaginal wall while holding the speculum in their left hand.

[0003] Currently, most existing biopsy forceps are designed for cervical biopsies. They are very difficult to use for biopsies of the vaginal wall, especially the vaginal wall of the cervical fornix and the vaginal wall of the vaginal stump after a total hysterectomy. Furthermore, because the vaginal speculum occupies considerable operating space, these forceps are difficult to position. This makes it challenging for the surgeon to perform biopsies of the vaginal wall, especially in difficult areas, under colposcopy. It also tends to lead to longer operation times, which is detrimental to treatment and often requires an assistant, causing inconvenience in clinical work. The patent title is "A Vaginal Biopsy Forceps," and the patent number is ZLCN201920690362.6. A Chinese utility model patent published on March 31, 2020, includes an operating rod. One end of the operating rod is fixedly equipped with a scissor-holding part, and the end of the scissor-holding part away from the operating rod is fixedly equipped with a rotating joint. A support frame is fixedly equipped on the rotating joint, and an opening and closing mechanism is fixedly equipped inside the support frame. Two spoon-shaped clamps are symmetrically connected to the opening and closing end of the opening and closing mechanism. Multiple needles are fixedly provided on the inner side of the jaws of the clamps, and a cutter is fixedly provided on the outer side of the jaws. A steel cable is connected to the end of the opening and closing mechanism away from the closing side, and the end of the steel cable away from the opening and closing mechanism passes through the operating rod and is fixed to the scissor-holding part. However, although the rotating joint in this patent can help the clamps rotate, the vaginal space is small, and the rotation range of the clamps is limited. Moreover, since a vaginal speculum needs to be operated simultaneously, the operating structure at the end of the operating rod also hinders rotation, making operation inconvenient.

[0004] How to solve the above problems has become an urgent technical issue. Utility Model Content
