[0002] In the medical field, when removing skin lesions such as warts, corns, calluses, etc., liquid nitrogen is often applied to the skin lesions for treatment. The existing application method mostly uses a cotton swab to absorb liquid nitrogen and apply it to the skin lesions. This application method is not controllable because the size of the cotton swab is fixed and not fit the size of the lesion well. When applying to lesions in concave places such as nail crevices, liquid nitrogen is easily in contact with normal skin, thereby damaging the normal skin. Therefore, in response to this problem, how to design a detachable single-disposable freezing device has become a problem that we currently need to solve. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Refer to the instruction manual Figure 1-5 ,like Figure 1 As shown, a detachable disposable freezing device according to an embodiment of the utility model comprises a pen holder 1, as shown in FIG. Figure 2 As shown, a mounting joint 2 is fixedly installed at one end of the pen barrel 1, a magnet 3 is fixedly installed at one side of the mounting joint 2, an annular convex plate 4 is fixedly installed on the outer side of the pen barrel 1, and a transparent protective cover 5 is slidably connected to the outer side of the pen barrel 1. Through the setting of the transparent protective cover 5, the push-pull transparent protective cover can cut the most suitable cross-section of the skin lesion size up and down, fit the shape of the skin lesion, be transparent and visible, and protect normal skin. The transparent protective cover 5 is slidably connected to the outer side of the annular convex plate 4, as shown in FIG. Figure 4 As shown, a positioning rod 6 is inserted into the interior of the mounting joint 2, a fixing member 7 is fixedly installed at one end of the positioning rod 6, a ring-shaped iron sheet 8 is fixedly installed inside the fixing member 7, and a freezing head 9 is fixedly installed on one side of the fixing member 7. Figure 3 As shown, a hanging part 10 is fixedly installed at one end of the pen body 1, the port diameter of the transparent protective cover 5 is smaller than the maximum diameter of the annular convex plate 4, and the inner wall diameter of the transparent protective cover 5 is larger than the maximum diameter of the annular convex plate 4.

[0022] It should be noted that, when the freezing head 9 needs to be installed, the positioning rod 6 is inserted into the interior of the mounting joint 2, and the annular iron sheet 8 is fitted with the magnet 3 under the attraction of the magnet 3, and the annular iron sheet 8 is fixed by the magnetic force of the magnet 3, and then the freezing head 9 is installed on one end of the pen body 1 and fixed by magnetic attraction, which is convenient for quick disassembly and replacement and is also beneficial for cleaning the pen body 1. When removing warts, the freezing head 9 is used to absorb liquid nitrogen and apply it to the wart. Since the freezing head 9 is made of artificial fiber hair, it has a hard texture and a strong ability to adsorb liquid nitrogen. After being moistened with alcohol, it is easy to shape it to fit the shape of a larger skin lesion, and then it is dipped in liquid nitrogen to shape it immediately. When treating larger skin lesions and irregular shapes, the shaping force is stronger. The thick upper and thin lower setting of the freezing head 9 is suitable for small skin lesions at the same time, reduces pain, and is more suitable for recessed positions such as nail crevices. Three sizes of freezing heads 9 are provided, so that a suitable freezing head 9 can be selected according to the size and shape of the skin lesions, which is beneficial for applying liquid nitrogen to the skin lesions.

[0023] Further, such as Figure 5As shown, a mounting hole is provided on one side of the mounting joint 2, and the positioning rod 6 can be inserted into the mounting hole. The types of freezing heads 9 are divided into type A freezing heads 91, type B freezing heads 92, 93 and the like. The length of type A freezing head 91 is 2 cm, and the end diameter is 1 cm. The length of type B freezing head 92 is 2 cm, and the end diameter is 8 mm. The length of type C freezing head 93 is 1.2 cm, and the end diameter is 5 mm.

[0024] It should be noted that, when the transparent protective cover 5 is used for treatment, the appropriate cross-section of the freezing head 9 is selected according to the size of the skin lesions, so that the maximum exposed diameter of the freezing head 9 is not larger than the diameter of the skin lesions, thereby protecting normal skin; each patient uses an independent freezing head 9, which is discarded after treatment. When not in use, the freezing head 9 is stored separately from the pen body 1, and a suitable model is selected for installation before use. When the pen body 1 is not in use, the transparent protective cover 5 is pushed and pulled to slide in the direction of the freezing head 9, so that the freezing head 9 is covered inside the transparent protective cover 5, and the transparent protective cover 5 is limited by the annular convex plate 4, so that the transparent protective cover 5 can stop after sliding to the appropriate position, thereby avoiding the transparent protective cover 5 from separating from the pen body 1 or not completely covering the freezing head 9 on the inside. At the same time, the pen body 1 can be hung up by the hanging part 10 for easy placement and retrieval when used next time.
