Description

Technical Field

[0001] The utility model relates to the medical field, in particular to a vaginal dilator with adjustable length. Background Art

[0002] Vaginal dilators are also called vaginal expanders. They are composed of two leaves and a handle. They are mainly used for routine gynecological examinations and surgeries. I believe that women who have undergone gynecological examinations will not be too unfamiliar with this instrument. Vaginal dilators usually used for surgery are usually made of metal materials, while those used for general gynecological examinations are usually made of polystyrene, polypropylene and other materials.

[0003] At present, most dilators can only be used for inspection at a fixed length. When facing patients with different body shapes, the fixed-length dilator may sometimes be too long or too short, resulting in unclear observation, so it needs to be replaced, which is not convenient. Therefore, those skilled in the art provide a vaginal dilator with adjustable length to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a vaginal dilator with adjustable length. When the device is in use, the user can adjust the length of the device according to the different patients to adapt to more patients. In this way, when facing different patients, there is no need to replace dilators of different lengths, which is also beneficial for the user to better observe the patient's diseased parts to achieve better medical effects. Compared with the existing dilator, when the device is in use, the light source will automatically turn on when the dilator is turned on, and will go out when it is closed, which is beneficial to saving the use time of the device and is beneficial for the user to receive more patients.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vaginal dilator with adjustable length, comprising a sliding member, a lower dilating leaf and an upper dilating leaf, the lower dilating leaf comprising a lower main body, the upper dilating leaf comprising an upper main body, a No. 2 fixing block is fixedly arranged in the middle of the upper end of the lower main body, a protective shell is fixedly arranged on the upper side of the front end of the lower main body, a No. 1 transmission shaft is rotatably arranged inside the No. 2 fixing block, a No. 1 bevel gear is fixedly arranged at the front end of the No. 1 transmission shaft, a screw is fixedly arranged on the other side of the No. 1 transmission shaft, a No. 2 transmission shaft is rotatably arranged on one side of the protective shell, a No. 2 bevel gear is fixedly arranged on one side of the No. 2 transmission shaft, and the No. 1 bevel gear is meshed with the No. 2 bevel gear;

[0006] The sliding member comprises an upper leaf and a lower leaf, wherein the upper leaf is slidably arranged at the rear side of the lower end of the upper body, and the lower leaf is slidably arranged at the rear side of the upper end of the lower body, a No. 1 fixing block is fixedly arranged in the middle of the front end of the lower leaf, two protrusions are fixedly arranged on both sides of the lower end of the upper leaf, and two grooves are provided on both sides of the upper end of the lower leaf;

[0007] Connecting blocks are fixedly arranged on both sides of the front end of the lower body, and light sources are fixedly arranged on opposite sides of the two connecting blocks, and switches are fixedly arranged on the same side of the rear ends of the upper body and the lower body;

[0008] The above technical solution is helpful to connect the upper expansion leaf and the lower expansion leaf together, and it is helpful to turn on the light source through the switch.

[0009] Furthermore, a handle is fixedly provided at the lower side of the front end of the lower body, and an adjusting gear is rotatably provided inside one side of the upper end of the handle;

[0010] Through the above technical solution, when the device is in use, the No. 2 transmission shaft can drive the No. 2 bevel gear to rotate, the No. 2 bevel gear drives the No. 1 bevel gear to rotate, the No. 1 bevel gear drives the No. 1 transmission shaft to rotate, and the No. 1 transmission shaft drives the screw at the rear end to rotate. When the screw rotates, it will drive the lower leaf to move back and forth, and when the lower leaf moves, it will also drive the upper leaf to move. The forward and backward movement of the upper and lower leaves is controlled by rotating the screw to accommodate more patients. Through the switch, the device is closed when the upper expansion leaf and the lower expansion leaf are not opened, and the connection will be disconnected after opening. At this time, the light source will be turned on, saving the time of turning on the light source when in use.

[0011] Further, the upper expansion leaf is rotatably arranged at the upper end of the lower expansion leaf;

[0012] The above technical solution is helpful for examining the patient's vagina.

[0013] Furthermore, a handle is fixedly provided on one side of the second transmission shaft, and the second transmission shaft is rotatably provided on one side of the lower body;

[0014] The above technical solution helps the user to rotate the No. 2 transmission shaft more easily, and the rotation setting of the No. 2 transmission shaft on one side of the lower body also helps to make it rotate more smoothly.

[0015] Furthermore, a handle is fixedly provided at the lower side of the front end of the upper body, and a tray is fixedly provided at the lower end of the handle;

[0016] The above technical solution is helpful for the user to better control the opening of the upper expansion leaf and the lower expansion leaf.

[0018] The above technical solution is helpful to fix the adjusted angle between the upper expansion leaf and the lower expansion leaf, which is convenient for the user's subsequent operation.

[0019] Furthermore, the four protrusions are clamped and arranged inside the four grooves, and the screw rod and the first transmission shaft are threadedly sleeved in the middle of the first fixing block;

[0020] The above technical solution is conducive to driving the upper blade to move when the lower blade moves forward and backward, and the screw rod, the No. 1 transmission shaft and the No. 1 fixing block are conducive to driving the lower blade to move forward and backward.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes a vaginal dilator with adjustable length. When the device is in use, the user can control the forward and backward movement of the sliding part by rotating the handle, so as to adjust the length of the device according to different patients to accommodate more patients. In this way, when facing different patients, there is no need to replace dilators of different lengths, which can save costs and is also conducive to the user to better observe the patient's diseased parts to achieve better medical effects.

[0023] 2. The utility model proposes a vaginal dilator with adjustable length. Compared with the existing dilators, the device does not need to manually turn on the light source when in use. When the dilator is opened, the light source will turn on automatically, and will go out when the dilator is closed. This helps to save the use time of the device and is conducive to the user to receive more patients. BRIEF DESCRIPTION OF THE DRAWINGS
