Abstract

The utility model discloses a steel tube type dermatome comprising a thin-wall steel tube and a solid inner core; wherein, the front end of the thin-wall steel tube is milled into a sharp blade edge and the back end is made into a knife handle. The solid inner core is sleeved inside the thin-wall steel tube, and the diameter is equal to the internal diameter of the steel tube. The front end of the solid inner core is a plane which is 0.5 to 0.8mm shorter than the length of the front end of the thin-wall steel tube. The back end of the solid inner core is embedded together with the back end of the steel tube and then jointly fixed. Compared with the prior art, the utility model has the advantages of shortening duration of surgery, simplifying surgery procedure, reducing surgery cost and dermatome waste, reducing scars in dermatome area. At the same time, the utility model also can enlarge skin supply area range with less damage to skin supply area.

Description

Steel pipe type dermatome

This utility model relates to a kind of dermatome, particularly a kind of steel pipe type dermatome.

The conventional dermatome that adopts of at present free skin-grafting has rolling dermatome, drum dermatome and electric dermatome, uses these dermatomes existing problems to be:＜1〉require bark fetching district broadness, smooth (thigh the place ahead bark fetching of being everlasting);＜2〉spready hide that takes off is the situation that approaches around the thick middle; When＜3〉cutting apart skin graft, need are incited somebody to action earlier, and the spready hide sheet of shrinkage is close on the gauze, slowly flatten, and then skin graft cut off into the longitudinal type slice together with gauze, the horizontal again square stamp shape of cutting off into the Semen phaseoli radiati size separates the skin graft of little stamp shape standbyly at last from gauze, whole process wastes time and energy, and also became uneven, not of uniform size of little stamp free skin graft, peripheral skin graft is wasted because of using especially;＜4〉skin-grafting area cicatrix at a specified future date is bigger, and the skin donor site damage is big, and oozing of blood is many, and cicatrix at a specified future date is also big;＜5〉operation cost height, large tracts of land skin grafting expense repeatedly is more than tens thousand of units.

The purpose of this utility model is to provide a kind of can shorten operating time, simplify operative procedure, reduce the operation cost, reduce the steel pipe type dermatome that skin graft is wasted, this dermatome can make the skin-grafting area cicatrix reduce, more attractive in appearance, also can enlarge the skin donor site scope simultaneously and make the skin donor site damage littler.

For achieving the above object, the solution that this utility model adopts is: it comprises thin-wall steel tube and entity inner core; the front end reconditioning of thin-wall steel tube becomes sharp blade; handle of a knife is made in the rear end; the entity inner core cover is in thin-wall steel tube; its diameter is consistent with pipe diameter, and its front end is the plane and lacks 0.5～0.8mm than the front end of thin-wall steel tube, and the rear end of rear end and steel pipe is chimeric and be fixed together.

The diameter of thin-wall steel tube is 0.6cm in the above-mentioned solution, and length is 10cm, and wall thickness is 0.3mm.

This utility model compared with prior art has following effect:＜1〉the bark fetching district no longer is confined to broadness, smooth position, in principle, but except that facial and joint bark fetching all;＜2〉bark fetching district skin lesion disperses, and oozing of blood is few in the recent period, recovers fast, and cicatrix at a specified future date is little;＜3〉small circular skin graft thickness unanimity, evenly big or small, more attractive in appearance after the skin-grafting, survival rate is higher, and cicatrix at a specified future date is littler;＜4〉skin graft that takes off can both be transplanted, and does not have waste in principle;＜5〉because of having saved the program that skin graft is cut apart, thereby shorten operating time greatly, reduced the operation cost.

Below in conjunction with drawings and Examples this utility model is described in further detail.

Fig. 1 is this utility model structure chart.

As can be known from Fig. 1, this utility model is made up of thin-wall steel tube 1 and entity inner core 2, and thin-wall steel tube 1 and entity inner core 2 are made by stainless steel material.The diameter of thin-wall steel tube 1 is about 0.6cm, length is 10cm, and wall thickness is about 0.3mm, and its front end reconditioning becomes sharp blade 1a, big ring-type handle of a knife 1b is beaten in the rear end, entity inner core 2 is enclosed within the steel pipe 1, and its diameter is consistent with the internal diameter of steel pipe 1, and its front end is the plane, after being inserted in steel pipe 1, its front end face is than the short 0.5～0.8mm of the front end of steel pipe 1, and the rear end of its rear end and steel pipe 1 is chimeric, and blended rubber cloth is fixed together.

Use of the present utility model is such: earlier with skin donor site routine disinfection, local anaesthesia, put towel, hold steel pipe 1 with the right hand then, the centre of the palm props up inner core 2, terminal knife edge 1a before the steel pipe 1 is pressed on the skin donor site skin, rotation two is cut by circular blade 1a down to surface, cuts repeatedly to required quantity; Holding stricture of vagina formula clamp with left hand lives and mentions circular skin edge front end, the right hand is held scalpel and is close to the skin crosscut and becomes razor graft, this skin graft directly is applied on the preprepared skin-grafting area wound surface then, repetitive operation to skin-grafting area wound surface all covers, after skin-grafting was finished, skin-grafting area and skin donor site were handled routinely.
