A device for removing vegetation

Abstract

The present invention relates to the technical field of excision devices, and discloses a vegetation excision device, comprising a cylinder, wherein two groups of rotating shafts are rotatably installed in pairs between the inner walls of the cylinder near the bottom, and an arc ring is fixedly installed between the two rotating shafts in one group.

When the cutter is excising a strip of warts, since the skin surface is previously coated with iodine disinfectant, blowing air through the air nozzle can accelerate the volatilization speed of the iodine disinfectant, thereby making the patient's skin feel cool, reducing local pain perception, and making the patient feel no obvious pain when the wart is excised, avoiding the problem of reducing pain by pressure, causing the wound to bleed and become larger, and affecting the patient's recovery.

Description

Technical Field

[0001] The present invention relates to the technical field of excision devices, and in particular to a vegetation excision device. Background Art

[0002] Skin warts are a type of skin growth caused by human papillomavirus, which is more common in children and young people. The incubation period is one to three months. It can spread by itself. The virus exists in the spinous cells and can promote cell proliferation and form wart-like lesions. According to the clinical manifestations and location, it is divided into common warts, flat warts, plantar warts, genital warts, oral warts, pharyngeal warts and verrucous epidermodysplasia. When removing warts, a special wart remover is required.

When the first spring 6 is compressed to the limit, the pressing block 5 is continued to be pressed down to move the limiting ring 4 downward, and the two guide pillars 12 are driven to slide along the inner wall of the L-shaped guide groove 13 through the limiting ring 4. When the guide pillar 12 slides to the oblique angle of the corner position of the L-shaped guide groove 13, the guide pillar 12 will slide along the oblique angle to the end of the L-shaped guide groove 13 and stop.
