The technical solution of the utility model is: two-way skin tractor, and its structure comprises: pull bar, two involutory needle trays, two loop bars, the two involutory pin of cover and two fixation clamps;
Wherein, described pull bar length is 200mm-300mm, and the pull bar upper surface is provided with serration; The two ends of loop bar have tip protrusion;
The two ends of fixation clamp have inside and outside two pairs with the supporting draw-in groove of described tip protrusion;
The involutory pin of two covers is installed on two loop bars by supporting buckle respectively;
Two loop bars are installed on two involutory needle trays by dismountable damascene structures respectively;
Two involutory needle trays are enclosed within the left and right two ends of pull bar respectively, involutory needle tray is provided with reverse card, cooperate the serration on the pull bar, guarantee the involutory needle tray unidirectional slip to the right on the left side, the involutory needle tray unidirectional slip left on the right, the move distance that the involutory needle tray on both sides slides from the pull bar both sides to central authorities is 150-200mm altogether.
Described pull bar length is preferably 240mm; The material of described involutory pin is preferably medical stainless steel, and the material of described pull bar, loop bar, involutory needle tray and fixation clamp is preferably polyformaldehyde; The spacing of the serration on the described pull bar is preferably 1mm.
When this utility model uses:
At first the involutory pin of a cover is embedded the skin edge 1cm place on the wound left side; Then involutory pin is installed on the loop bar by buckle, again this loop bar is nested on the involutory needle tray that has reverse card, then will this involutory needle tray be enclosed within the left side of pull bar; Secondly install another set of involutory pin, loop bar and involutory needle tray according to same der group, and will this involutory needle tray be enclosed within the right side of pull bar, slide the involutory needle tray on left and right both sides every day gradually to central authorities, the involutory pin pulling skin that drives left and right both sides is involutory to central authorities, and is until pin both sides by both hands that skin is involutory or by clinical requirement wound is left certain distance; At last fixation clamp is stuck on the tip protrusion at left and right involutory needle guard bar two ends, and then dismounting lower link and involutory needle tray.
The beneficial effects of the utility model: two-way skin tractor has simple in structure, easy and simple to handle, and can alleviate patient's misery, can be in involutory process fixing skin wounds distance arbitrarily.Except the less relatively situation of wound in the extremity open operation, also be applicable to the relatively large situation of wound in the abdominal part open operation, assert clinically that perhaps the skin folk prescription is to involutory inapplicable situation.
