Technical Field
[0001] The present invention relates to the technical field of medical devices, and particularly to a thermostatic vaginal speculum with an automatic expansion function. Background Art
[0002] A vaginal speculum is a gynecological examination instrument used to expose the vaginal wall and cervix, and preliminarily judge whether there are abnormalities or perform corresponding local treatments. When in use, it is necessary to separate the labia with the vaginal speculum, open the vagina, fully expose the vagina, cervix and vaginal fornix, observe whether the vaginal mucosa is normal, the color and characteristics of vaginal secretions, and the appearance of the cervix. At the same time, sampling of vaginal secretions, cervical smear, and vaginal gynecological surgery can be performed.
[0003] Currently, most of the vaginal speculum devices used clinically are in the shape of a duckbill, mainly composed of an upper lobe and a lower lobe to form an expander, and also include a handle and a fixing device. When in use, medical staff first insert the closed expander into the vagina, and then press the handle to open the expander for observation and operation inside the vagina. By pressing to open the expander, it is difficult to precisely control the degree of expansion. Since the physiological structures and relaxation degrees of the vaginas of different patients vary, it is difficult to meet the personalized expansion requirements. In addition, during the process of inserting the existing expander into the vagina, it will cause obvious pain and discomfort to the patient, resulting in poor cooperation of the patient, and thus poor diagnosis and treatment effects using this vaginal speculum device.

A self-heating material layer is arranged on the inner side of the expander, so that the expander has an appropriate temperature during the process of inserting into the vagina and expanding the vagina. A super-slippery coating is provided on the outer side of the expander, making the process of inserting the expander into the vagina lubricated, which can effectively reduce the discomfort brought to the patient, thereby improving the diagnosis and treatment effects of the vaginal speculum device. The problems in the background art are solved.

[0017] The beneficial effects of the technical solution are as follows:
[0018] 1. A thermostatic vaginal speculum with an automatic expansion function provided by the present invention connects a motor to a base. An output shaft of the motor is connected with a bidirectional lead screw that is rotatably connected with the base. The double-threaded lead screw is connected with a pair of sliders that are slidably connected with the base through threads with opposite helix directions. Starting the motor drives the bidirectional lead screw to rotate, and the pair of sliders move axially along the bidirectional lead screw in opposite directions (towards each other or away from each other) under the action of the threads and the base; an expansion component is connected to the pair of sliders, and the pair of expansion components achieve the opening and / or closing effects through the opposite movement, that is, the expansion body is controlled to open by the motor. The opening degree of the expansion body is controllable, and the opening precision is high, which can meet personalized needs;
[0019] The expansion matrix of the expansion component is detachably connected with an expander, so that after each use and / or for each patient, the expander can be replaced, avoiding the infection risk caused by repeated use of the expander and / or avoiding the cross-infection risk among patients; a self-heating material layer is arranged on the inner side of the expander, so that the expander has a suitable temperature during the process of inserting into and expanding the vagina, and a super-slippery coating is arranged on the outer side of the expander, so that the process of inserting the expander into the vagina is lubricated, effectively reducing the discomfort of the patient, thereby improving the diagnosis and treatment effect of the vaginal speculum device.

Air enters the self-heating material layer through the air inlet channel, and water or physiological saline enters the self-heating material layer through the liquid inlet channel. The iron powder in the self-heating material layer reacts with the oxygen in the air under the action of activated carbon powder, water / physiological saline and sodium chloride to release heat. Vermiculite is a heat-insulating material. After being acted upon by the heat released by the oxidation of iron powder, its volume expands to generate small air compartments to store air, thereby reducing the heat transfer speed inside the self-heating material layer, reducing the loss of heat energy, prolonging the heat release duration, and playing a heat preservation role.

The base is provided with a chute, and an expansion base body is slidably inserted through the chute. The chute guides and limits the sliding of the slider and / or the expansion base body, so that the relative movement process of a pair of expansion components is uniform and stable, further improving the opening accuracy of the expander.
