Problems solved by technology

In addition, the diameter and length of the scraping needle must also be considered. If the diameter is too large, the wound will be large and it will be difficult to perform precise operations. If the diameter is too small, the scraping efficiency will decrease.

Embodiment 1

[0016] Example 1: Three-hole pointed underarm odor shaving needle

[0017] see figure 1 , the three-hole pointed underarm odor scraping needle is composed of a straw body 1, a connector 2 and a handle 3. The straw body 1 is a cylindrical hollow tube, and the connector 2 is located at the tail end of the straw body. The diameter of the main body 1 is 3 mm, the length is 17 cm, the length of the connector 2 is 2 cm, the front end of the straw main body 1 is pointed, and it is a sharp open slope, and there is a positive side hole 5 near the slope in the same direction (front) as the slope, located on both sides of the slope. The side (90 degrees from the positive side hole 5) has a left hole 6 and a right hole 7. The three side holes have the same shape and are all rectangular with rounded corners. The length of the rectangle is 6.5mm and the width is 2mm. Close to the pointed end of the straw main body 1, the positive side hole 5 is 1.5 mm away from the pointed slope, and the...

Embodiment 2

[0018] Example 2: Four-hole pointed underarm odor scraping needle

[0019] see figure 2 The four-hole pointed underarm odor scraping needle is composed of a straw body 1, a connector 2 and a handle 3. The straw body 1 is a cylindrical hollow tube, and the connector 2 is located at the tail end of the straw body. The connector 2 is connected to the handle 3. The diameter of the straw body 1 is 3mm, the length is 17cm, and the length of the connector 2 is 2cm. The front end of the straw body 1 is pointed, which is a sharp slope in an open state; There is a reverse side hole 8 on the back (back side), and a left side hole 6 and a right side hole 7 are opposite to each other on both sides of the slope (90 degrees from the front side hole 5). The four side holes have the same shape and are rounded. Rectangle, rectangular length 6.5mm, width 2mm, positive side hole 5 is 1.5mm away from the slope, reverse side hole 8 is 5.5mm away from the tip, and the longitudinal distance betwe...

Embodiment 3

[0021] see image 3, use the three-hole pointed underarm odor scraping needle of Example 1, put the negative pressure suction device 4 into the suction pipe main body 1 through the handle 3, turn on the negative pressure to 0.1MPa, and the needle tip slope and the positive side hole 5 of the scraping needle face upward , perform see-saw scraping in the marked operation area, and press the needle with your hand (compression scraping). You can feel that with the scraping, the subcutaneous fat and sweat gland tissue are drawn out, and the skin flap gradually becomes thinner. The positive side of the scraping needle The negative pressure depression formed by hole 5 is clearly visible, and the apocrine glands under the dermis that are difficult to be removed by suction are scraped through the left hole 6 and the right hole 7 and the inclined surface. , radially scrape the entire operation area to complete the first round of scraping. Compared with the existing scraping needles of ...

Abstract

The invention provides an axillary osmidrosis suction and scraping needle with a pointed end. The axillary osmidrosis suction and scraping needle with the pointed end is composed of a sucker body, a connector and a handle, wherein the front end of the sucker body is the pointed end, a positive side hole is formed in a sharp inclined face in an open state and is located in the same direction with the inclined face, a left side hole and a right side hole are formed in the two sides of the positive side hole, and a three-hole suction and scraping needle is formed; or a negative side hole is formed in the back face of the positive side hole, and a four-hole suction and scraping needle is formed. According to the axillary osmidrosis suction and scraping needle with the pointed end, the number, the size and the arrangement design of the side holes are reasonable, a whole holding portion can be covered, sucked and scraped by the needle at a time, the suction and scraping holes are reasonable in arrangement, and the portion within the small range can also be sucked and scraped. The pointed end inclined face facilitates inserting of the needle tightly attached to the dermis deep face, meanwhile, the inclined face of the pointed end is an effective suction and scraping part, requirements of a surgery are met, using is safe and effective, and population and using are easy.

Description

technical field [0001] The invention belongs to a medical instrument, and relates to a pointed underarm odor shaving needle, which is a pointed underarm odor shaving needle used for treating underarm odor with a micro-incision negative pressure shaving method under swelling anesthesia. Background technique [0002] Axillary osmidrosis, commonly known as body odor and skunkhidrosis, is clinically manifested by the pungent and unpleasant odor of the sweat discharged from the bilateral armpits, which seriously affects the patient's life and social life, and causes psychological burden. It is more common in young people and often has family members. history. The main purpose of various current treatment methods is to completely destroy and remove the apocrine gland tissue located in the deep layer of the skin. In recent years, methods such as scratching and suction have less trauma and are easily accepted by the majority of patients, but the removal rate is often not high. At t...
