Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a constant temperature vaginal speculum with an automatic expansion function. Background Art

[0002] The speculum is a gynecological examination instrument used to expose the vaginal wall and cervix, to make a preliminary judgment on whether there is any abnormality or to perform corresponding local treatment. When using it, the speculum needs to separate the labia majora and minora, stretch the vagina, fully expose the vagina, cervix and vaginal fornix, observe whether the vaginal mucosa is normal, the color and properties of vaginal secretions, and whether the appearance of the cervix is ​​normal. At the same time, vaginal secretion sampling, cervical smears, and transvaginal gynecological surgery can be performed. Since the vagina is a fragile, sensitive and easily damaged organ, the comfort and safety of the speculum are extremely important.

[0003] The speculum in the prior art is usually made of stainless steel or plastic material, and the main body is a duckbill forceps connected by an elastic rotating structure. When in use, the medical staff needs to slowly insert the end of the speculum into the patient's vagina, and then hold the rotating end of the speculum with the hand and press it to drive the end of the speculum to open in the vagina. When it opens to the point where the medical staff can observe, the pressing force is stopped, and the existing pressing force is maintained so that the observation port formed by the speculum is stable for observation.

[0004] At present, the speculum in the prior art is made of stainless steel or plastic. When it is disinfected and used, it is cold and lacks a heating and constant temperature structure, which causes the patient's warm vagina to suddenly cool down and become extremely uncomfortable. In addition, the entire use of the speculum relies on medical staff to manually apply force to press the operation, and during observation, the medical staff needs to maintain a relatively constant pressing force to keep the speculum supported to carefully observe the internal conditions of the vagina. However, the manual force application by the medical staff is not stable and cannot guarantee stable output. Therefore, it is very easy to cause excessive force leading to excessive expansion or rapid expansion, resulting in damage to the vagina and severe pain for the patient. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose a constant temperature speculum with automatic expansion function. By providing an automated speculum with a constant temperature heating structure, an automated rotation structure and an integrated power supply control handle, the problem of lack of a constant temperature heating structure and an integrated structure of automated control and manual control in the prior art is solved, which causes the patient to feel severe discomfort due to the cold temperature of the speculum when it is used, and the speculum cannot be fully and automatically opened and fixedly supported, resulting in errors and injuries to the patient if it is only operated manually.

[0034] like Figure 1-10 As shown, an embodiment of the present invention is: a constant temperature speculum with automatic expansion function, including an assembled speculum body 1, the assembled speculum body including an upper support body 2 and a lower support body 3, wherein the lower support body is composed of a lower support plate 4 and a power supply control socket 5 fixedly arranged on the lower support plate, an electric heater power supply plate 6 is fixedly arranged at the front end of the lower support plate, the power supply control socket and the electric heater power supply plate are connected through a line tube 7, the upper support body is composed of a sliding support plate 8 and an upper support plate 9 rotatably arranged on the upper end of the sliding support plate, the sliding support plate and the left side of the upper support plate are connected through an electric rotating sleeve 10, so as to facilitate the realization of automatic rotation of electric control, the sliding support plate and the right side of the upper support plate are connected through a manual pressing rotator 11, which is conducive to the normal manual control rotation support to open the vagina for voyeurism without the need for automatic rotation of electric control, the electric rotating sleeve is connected to the power supply control socket through a line, and the line is hidden on the inner wall of the device.

[0035] A disposable duckbill plate is provided at the front end of the assembled speculum body through a snap-on electric heating structure, wherein the snap-on electric heating structure is composed of an electric heating metal snap joint 12 and a metal heat conductive snap interface 13, and the disposable duckbill plate is composed of an upper duckbill plate 14 and a lower duckbill plate 15, and the front ends of the upper support plate and the lower support plate are fixedly provided with electric heating metal snap joints, and the rear ends of the upper duckbill plate and the lower duckbill plate are provided with metal heat conductive snap interfaces, and the upper duckbill plate and the lower duckbill plate are provided with cavities inside, and the inner side of the cavities is filled with heat conductive liquid, and the heat conductive liquid is in direct contact with the inner wall of the metal heat conductive snap interface, and the outer wall of the metal heat conductive snap interface cooperates with the electric heating metal snap joint, so that when the two are snapped, they can be firmly connected and fixed and complete heat transfer. The electric heating metal snap joint is connected to the electric heater power supply board through a line.

[0036] A power supply control socket is fixedly arranged at the bottom of the assembled speculum body, and a matching power supply control handle 17 is assembled at the bottom of the power supply control socket. The power supply control handle includes a handle body 18, a connection plug 19 is fixedly arranged at the top of the handle body, a control instruction panel 20 is arranged behind the handle body, and a connection socket 21 is opened at the bottom of the power supply control socket. The connection socket consists of two holes, one of which is used to transmit current to power the entire device, and the other hole is used to connect the data line to transmit data signals so as to transmit instructions to the entire device. The top end face of the handle body is an electromagnetic adsorption surface 22, which is conducive to magnetic adsorption and fixed connection when the handle body and the power supply control socket are matched and connected, and the connection socket matches the connection plug, which is convenient for smooth insertion and connection. Inside the handle body, there are a rechargeable battery 26 for power supply and a central controller 27 for issuing control instructions.

[0037] A slide rail bolt 23 is fixedly arranged below the electric heater power supply plate, and a sliding through hole 24 is provided in the middle of the sliding support plate to facilitate the passage of the slide rail bolt. An electric threaded engagement sliding block 25 engaged with the slide rail bolt is fixedly arranged outside the sliding through hole, and the electric threaded engagement sliding block is connected to the power supply control socket through a line. Since the power supply control socket can transmit current and command signals at the same time, it is helpful for the electric threaded engagement sliding block to be directly controlled by the command input by the power supply control handle to complete the automatic sliding and drive the upper support body connected thereto to move, thereby realizing automatic expansion of the vagina. The upper support body is connected to the power supply control socket through the active line 16. Since the active line is long enough, the current and command signals can be provided to all the instruments on the upper support body through the corresponding lines to ensure the completion of the command.

[0038] When implementing this embodiment, first, the disposable duckbill plate is assembled onto the assembled speculum body, and then the connecting plug on the power supply control handle is inserted into the connecting jack of the power supply control socket, and the heating constant temperature command is input into the control command panel so that the current enters the electric heater power supply board and then transfers the energy to the electric heating metal card joint to heat it, and the heat of the electric heating metal card joint will be transferred to the metal thermal conductive card interface through contact heat transfer to finally heat the upper duckbill plate and the lower duckbill plate to the target set temperature. After preheating is completed, the disposable duckbill plate is coated with lubricating oil and then slowly inserted into the patient's vagina, and then the vaginal expansion speed and expansion width and the corresponding deflection angle pre-set in the control command panel are started. At this time, the central controller will control the electric threaded engagement sliding block to move upward along the direction of engagement with the slide rail bolt, and drive the sliding support plate to reach the target position according to the preset speed and vaginal expansion width, and then control the electric rotating sleeve to drive the upper support plate to rotate to the target position to complete the vaginal expansion, so that medical personnel can directly hold the power supply control handle for vaginal observation.

[0039] If manual vaginal dilation is required, after preheating, the sliding support plate can be manually pushed to move upward and then the manual pressing and rotating device can be pressed to complete the rotation of the upper support plate, thereby realizing manual vaginal dilation and vaginal voyeurism.

[0040] This embodiment provides an automated constant-temperature speculum that has a constant-temperature heating structure, an automated expansion structure, and an integrated power supply and control handle structure. By using a disposable duckbill plate, it is helpful to avoid virus transmission caused by repeated use of the tightly fitted parts of the equipment without thorough disinfection. By providing a constant-temperature electric heating structure, the heat transfer fluid in the inner cavity of the duckbill plate is heated by heat transfer from metal to achieve constant temperature of the equipment, which is helpful to improve patient comfort. The automated telescopic expansion and rotation structure can be used to provide a constant force and slowly and evenly open the instrument during testing to avoid damage to the patient's body. The power supply control handle can facilitate the realization of automated and convenient control.

[0041] In this embodiment, the disposable duckbill plate is made of hard plastic, which is conducive to making a smooth surface for easy use and can ensure hardness. At the same time, it also has the advantages of good thermal conductivity, light structure and low cost.

[0042] In this embodiment, the outer surfaces of the manual pressing rotator and the sliding support plate are provided with anti-slip grooves, which are beneficial to ensure that the holding and pressing will not slip in the manual operation mode, thereby ensuring the stability of the device.

[0043] In this embodiment, the control command panel is provided with an anti-mistaken-touch function structure, which is helpful to prevent wrong operation caused by mistaken touch when holding the power supply control handle.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
