Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a novel verruca remover and its using method. Background Art

[0002] Verruca is a kind of skin surface neoplasm caused by human papillomavirus. It is more common in children and young people, with an incubation period of 1 - 3 months and can spread by autoinoculation. The virus exists in the spinous cells, which can promote cell proliferation and form verrucous lesions. According to clinical manifestations and locations, it is divided into different types such as verruca vulgaris, flat verruca, plantar verruca, genital verruca (condyloma acuminata), oral verruca, pharyngeal verruca, and verrucous epidermal dysplasia.

[0003] For example, verruca vulgaris initially appears as a papule the size of a pinhead, and gradually grows to the size of a pea or larger, round or polygonal, with a rough surface like thorns, hard texture, grayish - yellow, dirty - yellow or dirty - brown color, and continues to develop into papillary proliferation. It is easy to bleed when rubbed or impacted. Usually, there is 1 initial lesion, which remains unchanged for a long time or continues to increase. Adjacent ones fuse with each other, and sometimes autoinoculation can occur.

[0004] It mostly occurs in teenagers, generally without obvious symptoms, and occasionally has tenderness; verruca vulgaris can occur in any part of the body, and is prone to occur on fingers, the back of hands, the edges of feet, etc., with a chronic course.

[0005] Currently, to deal with this virus, people generally go to the hospital for surgery. Since going to the hospital for surgery is troublesome, and this virus generally does not cause strong pain symptoms, many people choose not to treat it and let it run its course. However, in some cases, bleeding caused by friction or impact can cause discomfort; or in some remote areas where the medical system is not very sound, many people may also choose not to treat it, and it just keeps growing, and they just endure the discomfort.

[0006] For those who choose to go to the hospital, due to the strong recurrence of this virus, it is still easy to grow back repeatedly, and the effect of hospital surgery is not very good. Summary of the Invention

The top surface of the push button 5 is designed to be slightly convex, which is beneficial to the force application effect of the push button 5.

[0048] The push-pull holes 271 of the left and right jaws 21, 22 are gourd-shaped holes, which facilitate the assembly of the linkage shaft 44 (the first sub-shaft 441 and the second sub-shaft 442).

[0049] When the linkage rod 4 is pushed forward, it drives the left and right jaws 21, 22 to rotate outward along the fixed rotating shaft 161 respectively, so that the left and right jaws 21, 22 are opened; when the linkage rod 4 is pushed backward, it drives the left and right jaws 21, 22 to rotate inward along the fixed rotating shaft 161 respectively, so that the left and right jaws 21, 22 are closed. When the left and right jaws 21, 22 are closed, the two open cavities 23 jointly form a freezing chamber 28. The two first semi-circular notches 241 opposite to the left and right jaws 21, 22 are combined to form a clamping perforation 281, which is used for the patient to clamp the affected area during use; the two second semi-circular notches 251 opposite to the left and right jaws 21, 22 are combined to form an air guide hole 282, and the air guide hole 282 is used to conduct the cold air delivery channel 131 between the air outlet 31 of the cold air compression tank 3 and the freezing chamber 28; in this embodiment, the conical air outlet 13 is hermetically inserted into the air guide hole 282 of the freezing chamber 28 to realize the conduction of the cold air delivery channel 131 of the conical air outlet 13 and the freezing chamber 28.

The front cover 61 and the rear cover 62 can not only make the product look beautiful, but also protect the jaws from opening at will, and the rear cover 62 can protect the pressing block 15 from being accidentally pressed and pushed, thereby preventing the leakage of the refrigeration gas.

[0053] The outer wall of the main body 1 is designed to fit the palm of the hand and is provided with an anti-slip structure 63 to facilitate holding.

[0054] In actual application, the patient only needs to hold the novel wart removal instrument and push the push button 5 forward with a finger, so that the push button 5 drives the linkage rod 4 forward, thereby making the left and right jaws 21 and 22 rotate outwards along the fixed rotation axis 161 respectively, so that the left and right jaws 21 and 22 are opened. At this time, the opened positions of the left and right jaws 21 and 22 are aligned with the patient's affected part, and then the push button 5 is pushed backward to drive the linkage rod 4 to push (pull) backward, so that the left and right jaws 21 and 22 rotate inwards along the fixed rotation axis 161 respectively, so as to close the left and right jaws 21 and 22. At this time, the two first semicircular notches 241 opposite to the left and right jaws 21 and 22 are combined to form a clamping through hole 281, and the clamping through hole 281 clamps the patient's affected part;

[0055] The pressing block 15 is further pressed, and the pressing block 15 is squeezed toward the bottom of the cold air compression tank 3. The limiting valve 32 inside the air outlet 31 of the cold air compression tank 3 is squeezed to open, and a preset amount of refrigerant gas (compressed nitrogen) is discharged from the air outlet 31 of the cold air compression tank 3 along the cold air delivery channel 131 into the freezing chamber 28, so as to realize cryotherapy for the patient's affected part. Since the affected part is clamped (squeezed) by the clamping perforation 281, the freezing chamber 28 is in a closed state, and the cold air has a particularly good freezing effect on the affected part. In addition, the clamping of the affected part has the effect of external force solidification, which is more conducive to the falling off of the affected part.

[0056] Generally, the use process of this new wart removal device is set to set the cold air emission time to 15-20s for each treatment. The treatment course is generally 15-20 days, and 1-2 times a day is better.

[0057] Appropriate medicines may also be mixed into the cold air in the cold air compression tank 3 to enhance the therapeutic effect.

[0071] From the treatment effects of the above embodiments, it can be seen that this patent utilizes extrusion and freezing technologies. While using the front chuck to extrude the affected muscle, the affected area is quickly frozen at the same time. Since the sensitivity of the muscle decreases in the frozen state, there is no pain when the front chuck extrudes the affected area; at the same time, the freezing effect is conducive to the necrosis of the protruding wart and is beneficial to the shedding of the wart protrusion; therefore, this patent effectively treats the affected area, so that after the wart virus and muscle are separated, the skin surface of the affected area remains smooth and flat, without difference from the normal skin, and no wounds such as scars will be left.

[0072] And some patients are of the constitution prone to this disease. For example, Mr. Huang in Table 1 was treated at two affected areas simultaneously, and the effects were both good. This shows that the patented product is extremely convenient to use, can treat multiple affected areas simultaneously, has good treatment effects, and is extremely convenient.

[0073] The above embodiments and illustrations do not limit the product form and style of the present invention. Any appropriate changes and modifications made by those of ordinary skill in the art shall be regarded as not departing from the patent scope of the present invention.
