Vaginal dilator for gynecology

Abstract

The invention relates to the field of medical devices, and specifically discloses a vaginal dilator for gynecology, which comprises two handles with hinged parts on both upper and lower ends; the upper ends of the two handles are respectively rotatably connected with a placement cylinder, and the lower ends of the two handles are respectively connected with another handle. A placement cylinder is rotatably connected; each of the two placement cylinders defines a core rod and a push spring; the opposite ends of the two core rods are each connected with a combination seat, and the two combination seats are respectively combined with expansion pieces; each of the placement cylinders is provided with a non-return mechanism And a station slot, a handle is fixed with two limit blocks, when the handle is rotated to the rear of the two placement cylinders, the two limit blocks just enter into the two station slots respectively, at this time, the non-return mechanism allows the two core rods to move toward each other. The middle is close to prevent the two core rods from moving away. This gynecological vaginal dilator is based on the exquisite structural design, which is convenient and quick to use, with balanced expansion force and sufficient expansion space.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a vaginal dilator used in gynecological clinical examination and treatment. Background technique [0002] Vaginal dilator, also known as vaginal dilator, is often used to dilate the vagina in routine examination and surgical treatment of gynecological diseases to obtain a better inspection field or surgical field. It is a commonly used medical device in gynecology. The expansion wing and the handle are formed, the two expansion wings are duckbill-shaped and the rear ends are hinged, the handle is arranged at the rear end of the two expansion wings, the opening angle of the two expansion wings can be adjusted by the handle, and the position of the two expansion wings can be locked. This achieves the intended expansion purpose. Since most of the existing vaginal dilators adjust the degree of expansion by adjusting the opening angle, during clinical use, the degree of expansion applied by th...

Problems solved by technology

Since most of the existing vaginal dilators adjust the degree of expansion by adjusting the opening angle, in the course of clinical use, the expansion degree applied by the expansion wings to the vagina from the inside to the outside is often inconsistent and unbalanced, which is easy to cause The patient suffers severe pain or even contusion due to excessive local force; especially when the two expansion wings open at a large angle, although the inside of the vagina will be fully expanded, the part close to the vaginal opening is difficult to be fully expanded, and the vaginal dilator The rear port of the expansion wing is usually closed-loop, which often forms a "bottleneck" that hinders operations such as inspection and surgery; in addition, because the tail ends of the two expansion wings are connected by hinges, the hinges will block the doctor's line of sight to a certain extent

In summary, the structure design of the existing vaginal dilators is not reasonable enough. During use, it is difficult to adjust to the best dilation state according to the actual clinical conditions such as individual differences in patients and the purpose of dilation.
