Abstract

The utility model relates to a negative pressure type special skin-grafting apparatus, which is composed of a drum body 1, a cutter blade holder 2, a handle 3, a dial plate 4, a pointer 5, a shaft sleeve 6 for the cutter blade holder and a shaft 7 of the cutter blade holder, wherein, the drum body 1 with a closed type structure is provided with a negative pressure inlet tube 8 and the arc surface of the bottom of the drum body 1 is distributed with condensed absorption micropores 9. During a clinical operation, a film stripping pattern with the required skin-grafting graph is adhered at the arc surface of the bottom of the drum body 1.

Description

Negative pressure type special skin grafting apparatus

This utility model relates to orthopedic instruments; Particularly relate to the skin transplantation apparatus.

In clinical operations such as plastic surgery and burns unit, often need skin graft operation.Mostly common bark fetching method is manual bark fetching or utilizes drum dermatome to implement the apparatus bark fetching.But manual bark fetching needs comparatively a twist of the wrist, and bark fetching efficient is low, and thickness is difficult for grasping the bark fetching difficult quality guarantee; Utilize the drum dermatome bark fetching then can not need get the skin of arbitrary shape or different-thickness, and can only get the rectangle skin, and when bark fetching, be subject to blood and soak influence and cause gummed and get loose bark fetching failure by wound surface.In addition, existing two kinds of bark fetching methods because the skin surface all is a shiny surface, are unfavorable for transplanting surviving and the regeneration of bark fetching wound surface of skin.

The purpose of this utility model is at the above-mentioned defective of existing bark fetching method, and a kind of novel dermatome is provided.Compare with existing drum dermatome, its structure is science more, and it is more easy to operate, and function is more perfect, can overcome above-mentioned many shortcomings of existing bark fetching method effectively.

The purpose of this utility model is to realize by following technology solution.Change the bulging body of existing drum dermatome into sealed construction by Open architecture, and a negative pressure inlet tube is set at drum body end face or other suitable positions; Then be covered with dense absorption micropore on the curved surfaces of drum body bottom.During bark fetching, on the cambered surface of drum body, adhere to the disinfection film that a shape according to required bark fetching is carved with stripping pattern.Thin film can be selected for use and have flexible disinfecting paper or other soft materials.

Accompanying drawing 1 to accompanying drawing 3 is respectively facing, overlook and upward view of this utility model concrete structure.

Accompanying drawing 4 is the thin film stripping pattern exemplary plot that are carved with the bark fetching figure.

Followingly specific embodiments of the present utility model is elaborated with reference to accompanying drawing.

As shown in the figure, this utility model dermatome is made up of drum body 1, blade holder 2, handle 3, graduated disc 4, pointer 5, knife rest axle sleeve 6 and tool axis 7.Wherein tool axis 7 is slip with knife rest axle sleeve 6 and is rotatably assorted, and under handle 3 is handled, can drive blade holder 2 and both come and go slip vertically, comes and goes rotation, handle 3 dismounting arbitrarily again around the axle center.Compare with existing drum dermatome, this utility model dermatome has following characteristics:

1, rouses body 1 and change closed structure shown in Figure 1 into by Open architecture;

2, a negative pressure inlet tube 8 shown in Figure 1 is set at drum on the body 1, in order to when the bark fetching to the inner chamber input negative pressure of drum body;

3, on the cambered surface of drum body 1 bottom, be covered with dense absorption micropore 9 shown in Figure 3, in order to the skin that exposes in the stripping pattern pattern is attracted on the cambered surface of bulging body 1 tightly when the bark fetching because of suction function.

The clinical using method of this utility model dermatome is as follows: (1) is carved into the stripping pattern 11 of set pattern according to the needed shape of bark fetching on disinfection film shown in Figure 4 10; (2) the thin film stripping pattern 10 that will be carved with the bark fetching pattern sticks with glue on the cambered surface that is attached to bulging body 1 bottom; (3) cambered surface that will rouse body 1 is close to the position that needs bark fetching, and imports negative pressure through negative pressure inlet tube 8 to the inner chamber of drum body 1 with flexible pipe; (vacuum extractor or other negative pressure device in operating room are conventional indispensable) (4 thickness of bark fetching as required, turn graduated disc 4 is in order to adjust the distance of blade and drum body cambered surface; (5)) control crank 3, make blade holder 2 do axially to come and go along tool axis and slide; Slowly move forward blade holder 2 simultaneously and around the knife rest axle center, it is even to obtain thickness, and shape is identical with the stripping pattern pattern, and the surface has the skin of small embossment.

Utilize this utility model dermatome to carry out bark fetching when operation because the dual function of glue and negative-pressure adsorption makes the cambered surface of bulging body 1 and bark fetching district bonded more firm, and the influence that not soaked by blood, thereby can obtain the skin of arbitrary shape and all thickness, overcome the shortcoming that in the past can only get the rectangle skin, in addition, under the adsorption of absorption micropore and negative pressure, the skin surface of taking off is covered with small embossment, can help transplanting surviving and the regeneration of bark fetching wound surface of skin.

This utility model dermatome can be designed to the cambered surface of drum body bottom the tandem product of different radians according to different bark fetching areas.

Claims

1, a kind of negative-pressure type abnormity dermatome is made up of drum body (1), blade holder (2), handle (3), graduated disc (4), pointer (5), knife rest axle sleeve (6) and tool axis (7), and wherein tool axis (7) is slip with knife rest axle sleeve (6) and is rotatably assorted; It is characterized in that drum body (1) is a closed structure, and on drum body (1), a negative pressure inlet tube (8) is set; Be covered with dense absorption micropore (9) on the cambered surface of drum body (1) bottom.

2, according to the said negative-pressure type abnormity of claim 1 dermatome, when it is characterized in that clinical operation, the thin film stripping pattern (10) that is carved with the bark fetching pattern is sticked with glue on the cambered surface that is attached to bulging body (1) bottom.
