The bromhidrosis is sweat excreted by apocrine glands of armpit parts of patients, and fatty acid is light yellow and thick compared with common people; the fatty acid reaches a certain concentration, and bacteria on the skin surface, mainly staphylococcus, decompose to generate unsaturated fatty acid to generate odor. It has a smell similar to that of the anus of fox, and is therefore often called bromhidrosis. The traditional bromhidrosis treatment method comprises the following steps: 1. the external medicine is smeared, which is noninvasive but needs to be smeared repeatedly for a long time; 2. subcutaneous injection of hardening agent, including absolute alcohol, hemorrhoid eliminating medicine, etc. with poor curative effect and easy recurrence; 3. laser treatment belongs to the field of heat injury, which has great damage to skin and poor treatment thoroughness; 4. compared with the traditional bromhidrosis suction and scraping operation, the armpit skin flap excision operation is relatively safe at present, and the high-efficiency bromhidrosis minimally invasive suction and scraping operation (also called bromhidrosis minimally invasive suction and scraping operation) is widely applied to clinic. The underarm odor minimally invasive suction and scraping operation is to make a small incision on the skin at the armpit, suck and scrape apocrine glands in deep dermis and subcutaneous superficial fat by adopting a suction and scraping instrument, destroy apocrine glands and gland ducts, block secretion of sweat and completely reserve the armpit skin, so that the purpose of treating the underarm odor is achieved.

Through retrieving, the patent document with the publication number of CN103417259A discloses a tip bromhidrosis drawing and scraping needle, which consists of a suction pipe main body, a connector and a handle, wherein the suction pipe main body is a cylindrical hollow pipe, the head end of the suction pipe main body is in a closed conical shape, the connector is positioned at the tail end of the suction pipe main body and is connected with the handle through the connector, a positive side hole is formed near the head end, a left side hole and a right side hole are formed on the side surface which is 90 degrees with the positive side hole, the longitudinal distance between the positive side hole and the tip of the head end is 4.5mm, and the longitudinal distance between the left side hole and the right side hole is 1.5mm. In the surgical procedure of the micro-invasive suction and scraping operation of bromhidrosis, multiple rounds of suction and scraping can be performed, the purpose is to carefully and fully scrape the whole apocrine gland area, so that the residual apocrine gland is reduced as much as possible, and the recurrence rate is reduced.

In summary, we propose a micro-invasive L-shaped tube type suction scraper for treating bromhidrosis to solve the above technical problems.

Disclosure of Invention

The utility model aims to solve the problems that in the prior art, when in operation, skin is required to be pinched by fingers, the operation is complex, the suction efficiency is low due to the fact that the suction working face is a line, the tissue in the subsequent operation area is thin, and the tissue damage is easy to cause due to the fact that the contact area between a needle head and the tissue is too small.

The utility model adopts the technical scheme that the suction scraper for the bromhidrosis minimally invasive surgery comprises a scraping and sucking part and a connecting pipe, wherein one end of the connecting pipe is communicated with the scraping and sucking part, and the whole body is L-shaped; the scraping and sucking part is of an arc-shaped tubular structure, a sucking hole is formed in the side wall of the scraping and sucking part, and scraping blades are arranged around the sucking hole. The connecting pipe has the function of extending the scraping and sucking part to the vicinity of the tissue to be scraped and sucking part, and has the function of a channel through which the scraped tissue is sucked and discharged. The scraping and sucking part is provided with a suction hole, so that two operations of scraping the tissues and sucking the tissues out of the body are performed simultaneously.

The scraping and sucking part is integrally a section of arc, the sucking hole is a notch formed in the outer side wall of the scraping and sucking part, and the scraping blade is arranged around the notch. Preferably, the arc-shaped tubular scraping and sucking part can scrape off tissues and also can gather scraped off tissues during operation. The scraping edge arranged along the notch meets the function of scraping target tissues, and meanwhile, the scraping edge has a certain convergent beam, so that the scraping edge cannot cause additional damage to a patient, and the weak part cannot be easily damaged in the process of scraping for many times.

The suction hole is arranged at the left side or the right side of the scraping and sucking part, the opposite side is a suction hole wall, and the groove surface of the suction hole has an offset angle with the central axis, and the angle is between 1 and 60 degrees. Preferably, the difference of handedness causes the left-handed and right-handed separation, so that the utility model makes two designs in principle without damaging the structure of the suction hole, namely the suction hole is arranged on the left side of the scraping and sucking part and the suction hole is arranged on the right side of the scraping and sucking part, so that doctors with different handedness can use the suction hole. Meanwhile, due to the offset design of the suction hole, one side of the scraping blade is close to the tissue, and the other side of the scraping blade deviates from the tissue, so that a doctor can conveniently adjust the working position of the scraping blade by adjusting the lifting height of the arm when using the suction device.

The cross section of scraping and sucking part is the circular arc of C font, and circular arc main part is scraping and sucking part pipe wall, and circular arc inner space is the suction port, scrapes the edge setting in scraping the edge of sucking the pipe wall, sets up along the extending direction of circular arc. Preferably, the C-shaped structure is formed by cutting an arc on a circle in the section view due to the opening of the suction hole, the length of the arc is between one fourth and one half of the circumference in order to meet the requirements of scraping and suction at the same time, and the scraping blade is arranged on the suction hole, and the section extends along the direction of the circle where the arc is positioned.

The scraping blade is made of metal material, the shape of the scraping blade is consistent with the shape of the notch of the suction scraping part, the scraping blade is in a closed ring shape, and the cutting edge is obliquely directed into the ring shape. Preferably, to meet the scraping requirements, the blade must be sufficiently sharp and tough, and be made of a metal material with good effect, low production cost and high cost performance. The shape of the cutting edge is consistent with that of the notch of the scraping and sucking part, the cutting edge is obliquely directed to the annular inner part, the scraping edge extends along the cut part of the circular arc, and the benefit of directional converging is that an operator can control whether the cutting edge is contacted with target tissues or not through the height lifted by hands.

The projection of the connecting pipe on the plane of the scraping and sucking part is straight, and the surface perpendicular to the plane of the scraping and sucking part is provided with radian. Preferably, if the connecting pipe is straight, the front suction scraper part positioned under the skin is not easy to contact the skin when sucking and scraping sweat glands under the skin, and the sucking and scraping are not clean, and the illness state is repeated, so the connecting pipe is designed to have a small radian, and the front suction scraping part is lifted to contact the skin when in use. The design meeting the conditions is quite many, as long as the radian is guaranteed in the direction perpendicular to the plane of the scraping and sucking part, but the radian is designed only in the direction perpendicular to the plane of the scraping and sucking part due to the consideration of the suction strength and the manufacturing difficulty, and the straight pipe is seen from the plane of the scraping and sucking part.

One end of the connecting pipe, which is far away from the scraping and sucking part, is communicated with a negative pressure suction pipe connector, and one side of the connecting pipe, which is close to the negative pressure suction pipe connector, is fixedly provided with an operating handle. Preferably, the connecting tube serves, on the one hand, to extend the scraping and sucking portion to the vicinity of the tissue to be scraped and, on the other hand, to serve as a passage through which the scraped tissue is sucked and discharged. The negative pressure suction tube interface is used for connecting a negative pressure suction device to provide suction force. If the connecting pipe is directly controlled during operation, on one hand, the operator is inconvenient to exert force, the control is difficult, on the other hand, the connecting pipe is thinner, the improper force is very easy to cause the instrument damage, and therefore the existence of the operating handle is very important.

The connecting pipe is far away from one side of the scraping and sucking part and is provided with a pressure relief hole, the pressure relief hole is arranged at the position of the connecting pipe corresponding to the operating handle, and the operating handle is provided with a communication hole in butt joint with the pressure relief hole. Preferably, the operating handle is a mechanism covered outside the connecting pipe, a pressure relief hole is formed on one side of the connecting pipe away from the scraping and sucking part, and the pressure relief hole corresponds to the connecting hole, and the hole penetrating through the handle is the connecting hole corresponding to the pressure relief hole. In the operation process, the negative pressure suction pipe is connected with the negative pressure suction device, and the connecting pipe correspondingly generates suction force, but the suction force is relatively weak due to the existence of the pressure relief hole, and when the suction force needs to be enhanced, the pressure relief hole is blocked by hands.

The interface of the negative pressure suction tube is positioned at the bottom of the operating handle and is connected with the suction tube of the negative pressure suction device. Preferably, the negative pressure suction tube connector is an extension of the connecting tube, and extends from the tail end of the operating handle, and the negative pressure aspirator is used as a medium-sized device, and the negative pressure suction tube connector is also required to be connected with the negative pressure suction tube for extension.

The length of the scraping and sucking part is between 0.5 and 3cm, the connecting pipe is arc-shaped, the length is between 6 and 20cm, and the inner diameter is between 2 and 5mm. Preferably, if the arc length of the suction scraper is smaller than 0.5 cm, the suction scraping surface of the suction scraper is too narrow, the operation efficiency is low, and if the arc length of the suction scraper is larger than 3cm, the arc length of the suction scraper is larger than that of the suction scraper, so that sweat gland tissues at the periphery of the armpit are not easily sucked and scraped due to limited space under the armpit odor skin; if the inner diameters of the suction scraper and the connecting pipe are smaller than 2mm, the lumen is too small, sweat gland tissue blocks scraped by the suction scraper are not easy to enter the negative pressure suction pipe joint at the far end of the handle through the pipe, if the inner diameter of the lumen is larger than 5mm, the outer diameters of the suction scraper part and the connecting pipe are larger than 5mm, the length of a skin incision is larger than 5mm, and the incision wound is overlarge; if the length of the connecting pipe is less than 6cm, for a patient with a large bromhidrosis lesion area, the sucking and scraping knife part at the far end of the instrument cannot reach the subcutaneous sweat glands sucking and scraping the part far away from the incision, and if the length of the connecting pipe is greater than 20cm, the instrument is too long, inconvenience is brought to operators in operating the instrument, and accurate operation is not easy to control in the front sucking and scraping knife part operation.

The scraping and sucking part is inserted into the diving gap (scraping and sucking working area), one side of the scraping and sucking part provided with the scraping blade faces to the surface to be cleaned, an operator holds the operating handle to move the sucking and sucking scraper back and forth to scrape the apocrine glands of the target area, in the scraping operation process, the arc-shaped scraping part has a large effective scraping area, the scraping efficiency is improved, the other end of the connecting pipe is connected with the negative pressure aspirator through the negative pressure aspirator interface, the scraped apocrine glands can be sucked away from the target area through the negative pressure aspirator interface after passing through the connecting pipe under the action of negative pressure aspirator, the sucking and sucking operation can be simultaneously carried out, the operation efficiency is improved, the scraping effect of the scraping and sucking part is prevented from being influenced by the scraped apocrine glands, the judgment of the operator on the scraping degree is also prevented, the safety in the operation is improved, in addition, the arc-shaped scraping part has the function of gathering the scraped apocrine glands to a certain extent, the suction efficiency of the scraped apocrine glands is improved, the contact area of the scraped apocrine glands in an arc-shaped tubular structure is more large, the operation efficiency and the damage of the tissue in the operation is prevented from being increased, and the safety is easy.
