Description

Cut the skin dermatome

Technical field

This utility model relates to a kind of medical machinery, especially a kind of skin dermatome of cutting.

Background technology

When burn or external force damage cause the serious skin of large tracts of land, need to use skin grafting impel wound healing.Usually the healthy skin that extracts from patient self skin donor site, and it is extended, this method can satisfy the transplanting demand of large tracts of land wound surface with the fritter skin donor site.The large-area burns patient often lacks healthy from body skin source, needs to use the bigger skin graft of the rate of spread.The outer large bamboo hat with a conical crown and broad brim doctor C.P.Meek of U.S.'s shaping in 1985 has released a kind of exquisite skin graft expansion technique, and special bark press can be made into the monolithic skin graft a plurality of stamp-like skins island.Yet the radiance of MEEK skin grafting is covered by the mesh grafting of release in 1963, and the production of bark press also stops thereupon.Mesh graft can be finished the treatment task of large-area burns, if but this technology has the specific requirement and the skin graft rate of spread will postpone epithelization greater than 1: 6 to skin source area; In addition, the operating flexibility of the mesh skin graft that the rate of spread is bigger is lower.Lack the treatment that Pi Yuan has still limited the large-area burns patients.

The utility model content

The purpose that this utility model is cut the skin dermatome is at above-mentioned technology the deficiencies in the prior art, provide a kind of realize the multiple skin graft rate of spread and can realize the big skin graft rate of spread cut the skin dermatome.

For achieving the above object, this utility model adopts following technical scheme:

This utility model is cut the skin dermatome, comprise chassis, cutter shaft bearing, be installed in the cutter shaft and the cork dish sickle at knife rest middle part, wherein cutter shaft is made up of 13 cylinder blades, interval 3mm between the adjacent knife blades, left and right side on the chassis is fixed with left-hand screw shaft bar, right handed worm support separately, on the left and right screw rod support screw rod and guide shaft is installed; Cutter shaft support, back knife shaft rack before the forward and backward side on chassis is fixed with are separately installed described cutter shaft by bearing above the forward and backward cutter shaft support, and cutter shaft bearing rearward end is equipped with driver, and the screw rod right-hand member stretches out the right handed worm support, are equipped with to drive the hands wheel; Described cork dish sickle comprises base and loam cake, wherein is provided with thread groove that cooperates with screw rod and the gathering sill that cooperates with guide shaft below the base, on cover and be provided with 13 slotted holes that adapt with described cylinder blade.

Above the wherein said forward and backward cutter shaft support disk cutter shaft over cap is housed also.

Wherein said driver is a handle.

Wherein said driver is an air motor.

Advantage and the good effect of cutting the skin dermatome of the present utility model is:

(1) a small amount of skin donor site can satisfy the transplanting requirement, even the TBSA burn surface area also can use 1: 4 skin graft rate of spread up to 60%;

(2) can realize 1: 9 the rate of spread;

(3) the fritter onal also can obtain utilizing, and is beneficial to the skin source of saving;

(4) the skin island is evenly distributed, skin island spacing is narrow and small, so epithelization is rapid, regular;

(5) do not link to each other mutually between the skin island, so indivedual skin island necrosis does not influence surviving of whole skin graft;

(6) the theoretical rate of spread of skin graft is consistent with the true extension rate;

(7) even use the bigger skin graft rate of spread, the postoperative cosmetic result also mesh graft with 1: 3 is the same.

Description of drawings

Fig. 1 is the three-dimensional decomposition chart that this utility model is cut the skin dermatome.

The specific embodiment

Below in conjunction with accompanying drawing, further describe the specific embodiment that this utility model is cut the skin dermatome.

In this utility model, it is the right side that a side that drives handwheel 33 is installed, and the opposite side opposite with it is the left side.

Referring to Fig. 1.The skin dermatome of cutting of the present utility model comprises chassis 1, cutter shaft bearing 12, is installed in the cutter shaft 32 and the cork dish sickle 15 at knife rest middle part, and cutter shaft 32 is made up of equally distributed 13 cylinder blades, interval 3mm between the adjacent knife blades.1 left and right side is fixed with left-hand screw shaft bar 5, right handed worm support 4 separately on the chassis, cutter shaft support 11, back knife shaft rack 31 before the forward and backward side on chassis 1 is fixed with separately; Screw rod 7 is installed and two guide shafts that play the guiding role 8 are installed by bearing 6 on the left and right screw rod support, described cutter shaft 32 and cutter shaft bearing 12 are installed above the forward and backward cutter shaft support, handle 16 is equipped with in cutter shaft bearing 12 ends, and this handle 16 also can be replaced by the other types drivers such as steam-driven motor (not shown) that are installed on the motor bracket 3; Above the forward and backward cutter shaft support, cutter shaft 32 tops also are equipped with disk cutter shaft over cap 13.Screw rod 7 right-hand members stretch out right handed worm support 4, and driving handwheel 33 is installed.Cork dish sickle 15 comprises base and loam cake, wherein is provided with thread groove that cooperates with screw rod 7 and the gathering sill that cooperates with guide shaft 8 below the base, covers on the cork dish sickle 15 and is provided with 13 slotted holes that adapt with described cylinder blade; Be provided with cork dish container 34 between base and loam cake, be placed with the cork dish on the container, this cork dish is adopted as the structure of Dutch Humeca company invention.

During use, corium faces down, and skin graft is applied on the cork dish of 42 * 42mm, thick 3mm, and the fritter onal suitably also can utilize after the splicing on the cork dish.After applying well, the cork dish is placed in the cork dish sickle 15 of this utility model, shake and drive handwheel 33, cork dish sickle 15 moves along screw rod 7, when through cutter shaft 32, shakes handle 16, making cutter shaft bearing 12 drive cutter shaft 32 rotates, 13 cutting dives forming cutter shaft 32 are about to skin graft and are cut into 14 rectangular leather straps, the wide 3mm of each rectangular leather strap, and cylinder blade only can cut off skin graft during cutting; After for the first time cutting is finished, cork spiraled to turn 90 degrees put into cork dish sickle 15, use the same method and carry out cutting second time, skin graft just is cut into the square bodily form skin island of 14 * 14 3mm * 3mm like this, and promptly available large-area burns are treated.Wherein after the skin graft cutting is finished, dentation wedge 10 is embedded the slotted hole of cork dish sickle loam cake, open the loam cake fixed screw then, gently downwards by dentation wedge 10, visible all skin islands were all attached on the cork dish when opening cork dish sickle loam cake again when loam cake was slightly upwards mentioned.Acting as of dentation wedge 10 prevents skin graft and the adhesion of cork dish sickle loam cake.

More than be preferred forms of the present utility model, according to the disclosed content of this utility model, some identical, replacement schemes that those of ordinary skill in the art can expect apparently all should fall into the scope that this utility model is protected.
