Description
Technical field
The utility model relates to the field of medical instrument technology, more particularly to a kind of minimally invasive water knife.
Background technique
Underarm odor is also known as body odour, bromhidrosis etc., is since the apocrine sweat gland at the positions such as patient's armpit, perineum (is called top slurry
Gland), secretion is largely in the faint yellow concentration for showing thick fatty acid and reaching certain, the bacterium through skin surface, mainly Portugal
The decomposition of grape coccus generates unsaturated fatty acid and stinks, similar with the smell that fox anus excludes, so being frequently referred to
Body odour.This taste is especially heavier with summer, for a long time, influences the social activity of patient, unsociable and eccentric psychology easy to form.
The method for the treatment of body odour is numerous at present, treatment method many types, comprising: operative treatment, laser therapy, freezing are controlled
Treatment, drug therapy etc., but current treatment means and surgical technic cannot obtain satisfied effect, it is typically several as follows to control
Treatment method::
1, traditional sweat gland resection
Traditional sweat gland resection is to cut off all sweat glands on armpit skin using Z-type S type notch.This method curative effect can
It leans on, can thoroughly cure underarm odor；But it is too big due to damaging, cause local skin defect, bleeding more, skin when suture needle, and suturing
Tension is big, limits double upper limb movable functions, easily causes wound infection, suture falls off, and causes biggish operative scar, influences
The movable function of limb, especially scar constitution person are more not suitable for.Therefore the therapeutic method of surgery be only applicable to it is serious, through other
The bad patient of method therapeutic effect, clinician's all unusual careful in selecting the method.
2, traditional Minimally Invasive Surgery
(1) therapy is aspirated, which is the application of liposuction clinic, and the comparison that general cosmetic surgery hospital does is more, and notch is small
Restore fast, but be easy to omit, apocrine sweat gland mainly divides subcutis, and minority is distributed in shallow-layer fat, and suction method can be fully erased
Sweat gland in fat deposit, but to the apocrine sweat gland on fatty upper layer destroy removings degree it is inadequate, clinically be easy remain stink, cure rate compared with
Low, effective percentage is less than 70%；(2) apocrine sweat gland decollement, 2-3 centimetres of center cutout of the therapy armpit, surrounding are dissociated skin, successively
Removing, shallow-layer fat deposit and subcutis where removing apocrine sweat gland achieve the purpose that remove apocrine sweat gland；But decollement is because of wound
Mouth is small, and visual field limitation, surrounding is easy to omit, especially armpit arm end and chest end, and the patient big for apocrine sweat gland distribution comes
It says, nor good selection method.
3, laser
The treatments such as high-frequency electrical only do dotted treatment in skin surface, can not make the apocrine sweat gland of subcutaneous entire plane that can receive
To destruction, and it is inadequate to treat depth, once sweat gland regenerates, stink will continue to exist, will cause and burn sometimes, forms scar.
4, injection treatment
Can curative effect not be affirmed, effectively close and destroy on earth how many sweat gland after drug injection, also unknown, easily
Recurrence.
So Complications after surgical treatment is more just from the point of view of current treatment means, non-operative treatment often treats the symptoms, no
It effects a permanent cure, it is easy to recur.The apocrine sweat gland that armpit is only removed by surgery, eliminates the root for generating peculiar smell, could be from root
Underarm odor is treated on this.Therefore, it is badly in need of a kind of operation method for treating underarm odor or surgical instrument, not only can selectively removes sweat
Gland farthest retains normal tissue, and can be avoided complication, such as: longer scar, hemotoncus, cutaneous necrosis, scar are led
Draw, recur etc..
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of minimally invasive water knife, can be selectively clear
Except sweat gland, farthest retain normal tissue, realizes the surgical effects such as minimally invasive, accurate, quick, and structure meets ergonomic
It learns and requires, facilitate operation.
To achieve the goals above, the utility model provides a kind of minimally invasive water knife comprising: cutter head and handle, the knife
One end of head is arranged in the handle, and the side of the other end of the cutter head is equipped with the edge of a knife；The cutter head is from handle close to institute
