Description
Technical field
The sweat gland scalpel that this utility model relates to belongs to medical apparatus and instruments.
Background technology
Treat bromhidrosis before, the doctor removes subcutaneous sweat gland tissue with lumbar puncture needle.Its process is that this syringe needle is thrust armpit skin, aspirates and strikes off in different directions then.So on the one hand skin and subcutaneus adipose tissue are separated fully.In the process that pulls and pushes forward repeatedly, subcutaneous apocrine gland tissue is scraped on the other hand.This method has certain curative effect to alleviating bromhidrosis, and obtains general generally acknowledging.But this method has limitation, and efficient is low, generally wants more than one hour, and effect is not very good yet.This is that its needle tip is and narrow and small owing to the entry needle of having bent head is not to be used for scraping the sweat gland tissue specially, and generally all less than 2 millimeters, the area that can scrape is very little like this.In addition, all will retract syringe needle each before advancing pin, what at this moment do is idle work, has no to separate and scrapes the effect of cutting.The more important thing is that to want to have scraped subcutaneous cell very low by the efficient of the head of pushing pin, thereby increase the power of cutting of scraping because the angle of syringe needle is difficult to point to skin.And syringe needle points to the easy transdermal of skin.In addition, the meticulous sweat gland tissue that is unfavorable for that sucking-off scrapes of syringe needle.
Summary of the invention
The purpose of this utility model provides a kind of sweat gland scalpel, and it is fast to use this scalpel to remove subcutaneous sweat gland Tissue velocity, better effects if.
The technical solution of the utility model is: a kind of sweat gland scalpel is characterized in that: have the cutter head of cutter hub, cutter hub front end, the handle of cutter hub rear end, have on the cutter head towards front cutting edge and at least one towards rear knife edge.Described cutter hub is the pipe that is communicated with cutter head, handle, and the mouth of pipe of front and back end opens wide or sealing, and the rear end mouth of pipe is located at the handle end face.Can be provided with on the tube wall of front end and dump mouth, overlap with the top edge that dumps mouth towards rear knife edge.The cross section of cutter head is oblate or circular wherein a kind of.Cutter head the width at wide position more than or equal to the diameter of cutter hub.Preferable range can be the 2.5-8 millimeter.The preferable range of cutter hub diameter can be the 60-100% of the wideest position of cutter head width.Can there be nipple or pipe joint in the end of handle.The end of handle can be connected with vacuum pump by flexible pipe.Handle is provided with corresponding up and down concave surface, the tube wall of handle concave surface is provided with a radial direction through hole, the handle cross section of concave surface position is a truncated cone-shaped, and the perpendicular bisector of two parallel lines up and down of composition truncated cone-shaped is corresponding with point of a knife, and the pipe thickness preferable range of cutter hub can be the 0.2-0.6 millimeter.Optimum wall thickness can be 0.3 millimeter.Can tilt to axis direction towards front cutting edge.The mouth of pipe of described front end sealing is plugged with plastic plug on the support arm of its tube wall, and the outer rim of this plastic plug is connected with the mouth of pipe.
During use, scalpel is inserted the subcutaneous of oxter, and push ahead, use blade forward to come separate skin and subcutaneous tissue, protrude the pipe top towards front cutting edge and make blade sharp, tilt to axis direction, be difficult for transdermal towards front cutting edge.The cutter head shape of cross section is oblate and circular two kinds, and its oblateness can make cutter head laterally broaden, and blade is increased hypodermic facet, and increase work efficiency, and it is little that cutter head is the requirement of oblate shape tool setting body diameter on the other hand, thereby reduce incision length.When pulling back scalpel, just in time point to skin towards rear knife edge and scrape subcutaneous sweat gland tissue easily, dump on the mouth owing to being located at towards rear knife edge, the sweat gland that is scraped is organized to be dropped in the outlet fully, pipeline by scalpel inside, be connected the flexible pipe of handle end, negative pressure sucking-off by the vacuum pump generation, be located at the radial direction through hole may command suction on the tube wall, the handle surfaces at radial direction through hole place and corresponding behind are concave surface, and the handle cross section at concave surface place is a truncated cone-shaped, and concave surface has increased feel, can easily find the position and the point of a knife direction of through hole, and when concave surface can make the doctor point to push away scalpel forward or pull back scalpel, the fortune cutter was freely laborsaving, and the pipe thickness of cutter hub is reasonable, promptly satisfy the rigidity requirement, be difficult for curvedly, make pipeline unobstructed again, make to scrape thing and be eliminated completely.Define the maximum ga(u)ge that can scrape subcutaneous sweat gland tissue towards rear knife edge and the minimum range that dumps mouthful, make scrape cut operate safer convenient and swift.Present technique can be increased work efficiency, and operation safety is effective.
