Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a novel liquid nitrogen cryotherapy device. Background Art

[0002] Liquid nitrogen cryotherapy for warts is a commonly used treatment method that uses the low temperature (minus 196 degrees Celsius) generated by liquid nitrogen to destroy the tissue structure of the warts, causing them to lose their nutritional supply and gradually necrotize and fall off.

[0003] However, in actual use, some warts often grow in the vagina, so it is necessary to extend the probe into the vagina for treatment; this will make it difficult to observe.

[0004] Therefore, in order to solve this problem, we proposed a new liquid nitrogen cryotherapy device to facilitate the observation and treatment of warts in the vagina. Summary of the invention

[0005] In view of the defects in the prior art, the present invention provides a novel liquid nitrogen cryotherapy device to facilitate observation and treatment of warts in the vagina.

[0006] The novel liquid nitrogen cryotherapy device provided by the present invention comprises: a main body; and a treatment part, wherein the treatment part is arranged on the main body; the treatment part comprises a liquid nitrogen freezing element and an observation element; the liquid nitrogen freezing element is installed on the main body; the liquid nitrogen freezing element comprises a liquid nitrogen freezing generation nozzle; the liquid nitrogen freezing generation nozzle is installed at one end of the main body and communicated with an external liquid nitrogen source; the observation element comprises a speculum and an aperture; the aperture is installed on the main body and is located at the periphery of the liquid nitrogen freezing generation nozzle; the speculum is installed on the outside of the aperture, and the speculum is electrically connected to an external display for transmitting real-time images to the external display.

[0007] Furthermore, the treatment part also includes a pressure regulating valve, which is installed at the other end of the main body, and one end of the pressure regulating valve is connected to an external liquid nitrogen source. In actual use, the purpose of this design is to facilitate pressure adjustment; in this way, it is convenient for liquid nitrogen to enter the skin.

[0008] Furthermore, the treatment part also includes a connecting tube, one end of which is connected to the other end of the pressure regulating valve; the other end of the connecting tube is connected to the nitrogen freezing nozzle. In actual use, the purpose of this design is to facilitate the effective flow of liquid nitrogen and facilitate the liquid nitrogen to enter the liquid nitrogen freezing nozzle.

[0009] Furthermore, it also includes a heat preservation part, which is arranged in the main body and covers the outer wall of the connecting pipe. In actual use, the purpose of the heat preservation part is to insulate the temperature and prevent the excessively low temperature from being transmitted to the main body and then to the hands of the operator; this will affect the operation of the medical staff. The heat preservation part in this design is made of heat preservation cotton material, which can effectively solve the low temperature problem.

[0010] Furthermore, the treatment part also includes a pressing component, which is arranged outside the liquid nitrogen freezing nozzle and is located within the aperture. In actual use, the purpose of this design is to avoid the occlusion caused by the transmission of the image when pressing the wart, so that the wart disease site in the vagina can be effectively and conveniently treated.

[0011] Furthermore, the pressing assembly includes a pressing net, no less than three flexible connecting belts and no less than three abutting springs; the main pipe body is provided with a mounting groove; one end of the abutting spring is installed in the mounting groove, the other end of the abutting spring is connected to one end of the flexible connecting belt, and the other end of the flexible connecting belt is connected to the pressing net; one end of the pressing net is installed in the mounting groove, and the other end of the pressing net extends outward. In actual use, the purpose of this design is to facilitate the pressing of the wart diseased area. In this way, in the actual work process, the wart diseased area is effectively pressed by the pressing net, so that the pressed wart diseased area can be more conveniently frozen by liquid nitrogen; the wart diseased area is enlarged after pressing, and it is concentrated in the pressing net and close to the liquid nitrogen freezing nozzle; in this way, it is more convenient to freeze the wart diseased area with liquid nitrogen; and the combined design of the pressing net, the flexible connecting belt and the abutting spring adopted, on the one hand, makes it possible for the pressing net to press and move up and down under the action of the abutting spring; on the other hand, the flexible connecting belt also adopted becomes an effective connection method, and the material of the flexible connecting belt is rubber material; the function of the flexible connecting belt is also to facilitate subsequent work.

[0012] Further, the pressing assembly also includes a rotating motor and an outer gear ring; the outer gear ring is installed on the pressing net, and the rotating motor is installed on the main body; the rotating motor is meshed with the outer gear ring through a gear and drives the pressing net to rotate. In actual use, the purpose of this design is to facilitate the removal of the frozen wart disease part, that is, the wart, from the body. In actual work, the motor drives the outer gear ring, and the outer gear ring drives the pressing net to rotate. Under the rotating pressing net, the wart compacted by the pressing net can be effectively driven; and in actual operation, the motor and the flexible connecting belt in this design can realize flexible limiting on the one hand, so that in the process of rotating the pressing net, due to the limiting effect of the material of the multiple flexible connecting belts, the number of rotations is small, and under its continued driving, the pressing net is further extended upward until the flexible connecting belt can no longer be twisted and deformed under the effect of its own material; at the same time, it can further mortgage the wart during its upward extension, making it easier for the wart to fall off.

[0013] Furthermore, the pressing assembly also includes abutting pressing velvet; the pressing net is detachably mounted on the main pipe body; the abutting pressing velvet is mounted on the pressing net and passes through the liquid nitrogen freezing nozzle; the abutting pressing velvet is made of metal material, and the abutting pressing velvet abuts against the patient's diseased part. In actual use, the purpose of this design is to facilitate the detachment of the wart, and the abutting pressing velvet used is a filamentary metal, and the metal used is a nickel-titanium alloy; the metal can effectively work in a low-temperature environment; in actual work, the abutting pressing velvet is disposable, so that pollution is effectively reduced; at the same time, the abutting pressing velvet in this design is for contact with the wart, and when freezing with liquid nitrogen, it is convenient to transfer the freezing temperature of the liquid nitrogen to the wart, so that the wart can be quickly cooled and detached.

[0014] It can be seen from the above technical solution that the beneficial effects of the liquid nitrogen cryotherapy device provided by the present invention are:

[0015] (1) In actual use, the main body design adopted by the design makes it easy to hold, and the liquid nitrogen freezing nozzle is installed at one end of the main body, so that in the actual operation process, it can be used in a similar way to holding a pen to directly and quickly approach the wart; in this way, it can effectively facilitate medical personnel to learn and reduce the difficulty of learning and training;
