Summary of the invention
To above-mentioned weak point of the prior art; The present invention aims to provide the operation perching knife that a kind of corium cuts; Can under the situation of not exclusively cutting the epidermis and the epidermis that do not overturn, directly gather dermal tissue is used for Facial Depression filling or hypertrophic cicatrix excision etc. as packing material operation; Gather or excise convenient and swift, and reduce cicatrization behind the operation wound, reduced dermonecrotic generation.
Technical scheme of the present invention: the operation perching knife that a kind of corium cuts; The main cutting edge that it comprises cutter hub and is located at the cutter hub front end; Wherein, Be provided with and the opposite secondary cutting edge of said main cutting edge edge direction at said cutter hub front end, this pair cutting edge and cutter hub are the acute angle angle, and cutter hub is provided with the corium that is connected with acute angle root area between the cutter hub with said secondary cutting edge and collects mouthful.
Beneficial effect of the present invention: through a secondary cutting edge opposite with main cutting edge edge direction is set, and be the acute angle angle on the basis of traditional operation cutter, be communicated with a corium at its acute angle root area and collect mouthful through this pair cutting edge and cutter hub.When needs collection or excision dermal tissue, earlier main cutting edge is cut epidermal area, deeply to the corium tissue; Return and scrape; Scrape through secondary cutting edge and to get dermal tissue, and the dermal tissue of scraping taking-up is collected mouthful to come out from corium, like this; Just needn't need big wound to cut epidermal area as traditional dermal tissue collection, the operation perching knife among the present invention only needs to offer one at epidermal area can make Wicresoft's mouth of cutter hub entering get final product.Can obviously reduce tissue injury, reduce cicatrization, and increase safety and patient's acceptance, improve and used the application that patient face portion depression is filled by auto derma tissue transplantation in the surgical operation.In addition, can also be applied to the excision of hypertrophic cicatrix tissue.
Description of drawings
Fig. 1 is a structural representation of the present invention;
The specific embodiment
Come further explain the present invention below in conjunction with specific embodiment and accompanying drawing.
Referring to Fig. 1; The operation perching knife that said corium cuts comprises the cutter hub 1 of whole camber and is located at the main cutting edge 2 of cutter hub 1 front end; Wherein, Be provided with and the opposite secondary cutting edge 3 of said main cutting edge 2 edge directions at said cutter hub 1 front end, this pair cutting edge 3 is the acute angle angle with cutter hub 1, and cutter hub 1 is provided with the corium that is connected with acute angle root area 5 between the cutter hub 1 with said secondary cutting edge 3 and collects mouth 4.
Corium among the present invention is collected mouth 4 and is built up on the said cutter hub 1; It is connected to the acute angle root area 5 between said secondary cutting edge 3 and the cutter hub 1 through the passage that is built up in the cutter hub 1; When the dermal tissue that is scraped from the dermal tissue district by secondary cutting edge 3 passes through said acute angle root area; Collect mouth 4 through passage to corium again, thereby obtain dermal tissue, be used to fill Facial Depression from body.Perhaps directly through this operation perching knife excision hypertrophic cicatrix tissue, processing such as the later stage radiotherapy of pressure dressing, and combination then, the handling problem that can solve hypertrophic cicatrix and keloid very thorny in the present plastic surgery operations.
The position that is provided with for main cutting edge 2, secondary cutting edge 3; Said main cutting edge 2 is positioned at the extrados end of cutter hub 1 front end; And said secondary cutting edge 3 is positioned on the intrados of cutter hub 1 front end; The acute angle angle of this pair cutting edge 3 and said cutter hub 1 is 0.1～15 ° and should be arranged to low-angle by pair cutting edge 3, thereby mainly is in order to prevent that when performing the operation, once cutting dermal tissue too much damages the skin histology under the dermal tissue.Be preferably 10 °.The thickness of getting dermal tissue is once scraped in the size decision of this angle, can decide as the case may be.
Said main cutting edge 2, secondary cutting edge 3 and cutter hub 1 are one-body molded, make things convenient for the production of this product, simultaneously; The antibacterial surperficial because of scalpel is very big to the operation influence; Therefore, when performing an operation, all surgical knife tools need pasteurised completely; Through one-body molded, at connecting portion the halfway situation of sterilization takes place when avoiding sterilizing and take place.
The cross section full-size of said cutter hub 1 front end is 0.6～1cm, is preferably 1cm, meets the end size of traditional operation cutter, simultaneously, and because of the front end sectional dimension of cutter hub 1 is 1cm, so when cutting epidermal tissue, its opening is little.
The concrete method for using of the present invention is at first carried out anaesthetic treatment through the position that cuts dermal tissue at need, then cutter under the centre position; Leave the long wound of about 1cm through the main cutting edge 2 on the cutter hub 1, this operation perching knife is stretched to subcutaneous dermal tissue, then to pulling back; Scrape and get dermal tissue, the corium that the dermal tissue of getting of scraping amasss on cutter hub 1 is collected in the mouth 4, after having collected dermal tissue; Only need do wound about 1cm shrinks to close up and gets final product; Accomplish Wicresoft's mouth, cicatrization behind the minimizing operation wound can reduce dermonecrotic generation simultaneously.
