DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] References to "embodiments" in this specification mean that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of the present application. The appearances of this phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they independent or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0016] An embodiment of the present invention provides a cyclic heating type vaginal speculum, as Figures 1-4 shown. The cyclic heating type vaginal speculum includes: a bracket 1, on which a lower expansion shell 2 and an upper expansion shell 3 for vaginal dilation in obstetrics and gynecology with adjustable spacing are provided; a channel 4 opened on the lower expansion shell 2 and the upper expansion shell 3 for guiding a temperature-raising liquid; a handle 21 fixed on the bracket 1, on which a gripping sleeve is provided; a liquid supply mechanism provided on the bracket 1 for supplying the temperature-raising liquid into the channel 4; and an adjustment mechanism provided on the bracket 1 for adjusting the lifting of the upper expansion shell 3.

[0017] In this embodiment, when using the cyclic heating type vaginal speculum, medical staff first adjust the height of the upper expansion shell 3 through the adjustment mechanism to make the spacing between the lower expansion shell 2 and the upper expansion shell 3 reach a suitable size; then, use the liquid supply mechanism to supply the temperature-raising liquid into the channel 4 to make the temperatures of the lower expansion shell 2 and the upper expansion shell 3 appropriate; then, medical staff hold the gripping sleeve on the handle 21, place the lower expansion shell 2 and the upper expansion shell 3 into the patient's body, and further finely adjust the spacing through the adjustment mechanism to complete the vaginal dilation operation. During the operation process, the bracket 1 plays a role of stable support, and the lower expansion shell 2 and the upper expansion shell 3 achieve vaginal dilation through adjustable spacing; the channel 4 is used to guide the temperature-raising liquid to ensure that the speculum maintains a suitable temperature; the gripping sleeve on the handle 21 facilitates the medical staff to hold, the liquid supply mechanism ensures the continuous supply of the temperature-raising liquid, and the adjustment mechanism realizes flexible control of the lifting of the upper expansion shell 3. By introducing the temperature-raising liquid through the liquid supply mechanism and the channel 4, it effectively solves the problem that the traditional vaginal speculum has a low temperature in cold or low-temperature environments, resulting in discomfort for patients, relieves the muscle tension of patients, and improves the comfort during the examination process; the adjustment mechanism and the adjustable spacing design make the vaginal dilation operation more in line with the actual needs, are convenient to operate, and the setting of the handle 21 and the gripping sleeve enhances the stability of the medical staff during operation. At the same time, some components can be reused, which reduces the use cost on the premise of ensuring hygiene.

[0018] In a further preferred embodiment of the present invention, the liquid supply mechanism includes: a liquid storage bottle 9 fixed to the bottom of the bracket 1 for containing the temperature-raising liquid, and a liquid extraction pump 10 is arranged in the liquid storage bottle 9; a liquid outlet pipe 11 fixedly connected to the liquid outlet end of the liquid extraction pump 10; a flow dividing pipe 12 fixed to the liquid outlet pipe 11, and a first liquid guiding pipe 13 and a first telescopic pipe 14 are fixedly connected to the flow dividing pipe 12, and the liquid outlet ends of the first liquid guiding pipe 13 and the first telescopic pipe 14 are respectively communicated with the corresponding channel 4; an electric heating pipe 19 arranged in the liquid storage bottle 9.

[0019] In this embodiment, the temperature controller is used to control the electric heating pipe 19 to heat the temperature-raising liquid in the liquid storage bottle 9. The liquid extraction pump 10 extracts the heated temperature-raising liquid, and through the liquid outlet pipe 11 and the flow dividing pipe 12, it is transported to the channel 4 through the first liquid guiding pipe 13 and the first telescopic pipe 14, so as to realize the temperature adjustment of the vaginal dilator.

[0020] This liquid supply mechanism can effectively adjust the temperature of the vaginal dilator, avoid discomfort caused to patients due to too low temperature of the vaginal dilator, and relieve the muscle tension of patients.

[0021] In a further preferred embodiment of the present invention, the adjustment mechanism includes: a screw rod 5 assembled on the bracket 1 through a bearing; an assembly block 6 threadedly sleeved on the screw rod 5, and the assembly block 6 is fixedly connected to the upper expansion shell 3; a guide rod 7 slidably installed on the assembly block 6, and the top end of the guide rod 7 is fixedly connected to the bracket 1; a knob 8 fixed to the screw rod 5.

[0022] In this embodiment, when using the adjustment mechanism of the circulating heating type vaginal dilator, the medical staff rotates the knob 8 to drive the screw rod 5 to rotate on the bracket 1 under the support of the bearing. Since the assembly block 6 is threadedly sleeved on the screw rod 5, the rotation of the screw rod 5 causes the assembly block 6 to move along the axial direction of the screw rod 5. And because the assembly block 6 is fixedly connected to the upper expansion shell 3, the lifting of the upper expansion shell 3 is realized; during this process, the guide rod 7 plays a guiding role for the assembly block 6 to ensure the smooth movement of the assembly block 6, so as to accurately adjust the distance between the lower expansion shell 2 and the upper expansion shell 3.

[0023] In a further preferred embodiment of the present invention, a second telescopic pipe 15 and a second liquid guiding pipe 17 are fixedly installed on the lower expansion shell 2 and the upper expansion shell 3, and the second telescopic pipe 15 and the second liquid guiding pipe 17 are communicated with the corresponding channel 4 for guiding the temperature-raising liquid. The liquid outlet ends of the second telescopic pipe 15 and the second liquid guiding pipe 17 are communicated with a confluence pipe 16, and the liquid outlet end of the confluence pipe 16 is fixedly installed with a return pipe 18, and the liquid outlet end of the return pipe 18 extends into the liquid storage bottle 9.

[0024] In this embodiment, the heating liquid starts from the liquid supply mechanism, flows through passage 4 into the second telescopic tube 15 and the second liquid guide tube 17 that are connected to passage 4, and continues to be transported in these two tubes. Subsequently, the heating liquid enters the confluence tube 16 from the liquid outlet ends of the second telescopic tube 15 and the second liquid guide tube 17. After being collected by the confluence tube 16, it passes through the return tube 18 and finally returns to the liquid storage bottle 9 to form a circulating diversion of the heating liquid. During the diversion process, the second telescopic tube 15 and the second liquid guide tube 17 are responsible for transporting the heating liquid in passage 4 to the confluence tube 16. Their connection design with passage 4 ensures the stable inflow of the heating liquid; the confluence tube 16 collects the heating liquid flowing out of the second telescopic tube 15 and the second liquid guide tube 17, enabling the liquid to flow centrally towards the return tube 18; the return tube 18 sends the heating liquid back to the liquid storage bottle 9 to complete the entire diversion cycle. Each component cooperates with each other to ensure the orderly flow of the heating liquid in the vaginal dilator device.

[0025] In a further preferred embodiment of the present invention, a liquid replenishing port is provided on one side of the liquid storage bottle 9, and a plug 20 is arranged in the liquid replenishing port.

[0026] In this embodiment, when using the liquid replenishing structure of the liquid storage bottle 9 of the circulating heating type vaginal dilator device, when the heating liquid in the liquid storage bottle 9 is insufficient, the medical staff only needs to open the plug 20 and add heating liquid to the liquid storage bottle 9 through the liquid replenishing port; after adding an appropriate amount of heating liquid, cover the plug 20 back on the liquid replenishing port to complete the replenishment operation of the heating liquid and ensure the circulating supply of the heating liquid in the diversion structure.

[0027] In a further preferred embodiment of the present invention, a threaded hole is provided on the assembly block 6, and the threaded hole is adapted to the screw rod 5.

[0028] In this embodiment, the adaptation design of the threaded hole and the screw rod 5 allows the medical staff to easily adjust the position of the upper expansion shell 3 by simply turning the knob 8.

[0029] In a further preferred embodiment of the present invention, limit blocks are fixed on the bottom ends of the screw rod 5 and the guide rod 7.

[0030] In this embodiment, the screw rod 5 transmits power through the cooperation with the threaded hole on the assembly block 6, the guide rod 7 provides guidance for the assembly block 6, and the limit block is a key component to ensure the safety of the adjustment.

[0031] In summary, compared with the related technologies, the bracket 1 provides a stable support. The screw 5, the assembly block 6, the guide rod 7 in the adjustment mechanism cooperate with the limit block to realize the lifting and precise positioning of the upper expansion shell 3, ensuring the safe and stable adjustment of the distance between the lower expansion shell 2 and the upper expansion shell 3; components such as the liquid storage bottle 9, the liquid extraction pump 10, and the electric heating tube 19 in the liquid supply mechanism, combined with the diversion structures such as the channel 4 and the second telescopic tube 15, realize the circulation heating and transportation of the heating liquid, ensuring that the temperature of the vaginal dilator is appropriate; the handle 21 and the grasping sleeve facilitate the operation of medical staff, and the liquid replenishing port and the plug 20 facilitate the replenishment of the heating liquid.
