Description

Technical Field

[0001] This utility model relates to the field of surgical instrument technology, specifically a novel vaginal retractor used in carbon dioxide laser gynecological surgery. Background Technology

[0002] The primary function of a vaginal retractor is to open the vaginal wall, helping doctors observe the morphology, color, and mucosal condition of the vagina and cervix for any lesions; to provide operational space for collecting samples such as vaginal secretions and cervical cells; and to facilitate procedures such as vaginal medication administration and cervical physical therapy. Existing vaginal retractors are generally rod-shaped instruments composed of sleeves of different sizes and observation openings, mechanically opening the vagina to provide a field of vision and operational space. However, existing vaginal retractors have some shortcomings, such as: lack of a closed window, resulting in ineffective isolation of bodily fluids from the external environment and increasing the risk of cross-infection; insufficiently ergonomic design, leading to inconvenience and patient discomfort; difficulty in cleaning and disinfection, and a relatively complex structure, making thorough cleaning difficult and prone to leaving pathogen residues. Therefore, a more convenient and safer vaginal retractor is an indispensable and important auxiliary tool in gynecological surgery.

[0003] The vaginal retractor disclosed in patent application CN213405965U belongs to the field of medical device technology. It solves the problem that existing vaginal retractors easily act on non-working surfaces when the laser from a carbon dioxide laser therapy machine is misfired, causing medical accidents. This vaginal retractor includes a hollow cylindrical body. One end of the cylindrical body is open, and the open end has a radially outward-expanding cylindrical connecting portion. The outer cylindrical surface of the cylindrical connecting portion has external threads for connecting to the carbon dioxide laser therapy machine. The other end of the cylindrical body has a radially outward-expanding cylindrical inlet portion. The outer end of the cylindrical inlet portion is closed. A square opening is formed on the side wall of the cylindrical inlet portion adjacent to the closed end. A reflective mirror is obliquely fixed on the inner side wall of the cylindrical inlet portion, radially opposite to the square opening. This utility model is convenient to operate, highly accurate, and provides good protection.

[0004] However, this utility model lacks a closed window, making it difficult to isolate bodily fluids from the outside environment and increasing the risk of infection. Furthermore, the reflective surface of this utility model is fixedly installed inside the open window, making it difficult to thoroughly clean and disinfect when bodily fluids seep into the retractor, thus affecting its safety. Therefore, we propose a novel vaginal retractor for use in carbon dioxide laser gynecological surgery, which solves the problems of lacking a closed window and inconvenient disinfection and cleaning, improving the safety and effectiveness of this utility model.

Aluminum alloy and stainless steel have strong corrosion resistance, strength, and rigidity, are not easily deformed, and are convenient for repeated high-temperature and high-pressure sterilization.

[0027] This embodiment describes a novel vaginal retractor for use in carbon dioxide laser gynecological surgery. In use, a cylindrical positioning element 303 is fixedly installed inside the retractor housing 100 via positioning bolts 205. It is then connected to the carbon dioxide laser treatment machine via the connecting internal thread 308 of the limiting ring 307. The closure status of the sealing window 203 is checked. Through the 45-degree inclined reflective mirror 300 of the mirror observation mechanism, combined with the design of the light-transmitting port 202, doctors can easily and clearly observe the lesion area, ensuring precise positioning and effective treatment by the carbon dioxide laser treatment machine. The light-transmitting port 202 of the retractor is equipped with a sealing window 203, which effectively isolates bodily fluids from the external environment, preventing cross-infection and improving medical safety. The cylindrical design of the retractor housing 100, with rounded corners in its variable cross-section areas, is more ergonomic, facilitating doctor operation and effectively preventing tissue damage and reducing patient discomfort during use. In addition, the retractor adopts a double-layer cylindrical structure, and its mirror observation mechanism is fixedly connected to the retractor housing 100 by positioning bolts 205, which makes it convenient to disassemble the retractor housing 100 for thorough cleaning, disinfection or replacement, further improving the safety of use.
