Soft tissue debridement self-retractor described in the utility model comprises the fixed cover that section is rectangular, this above fixed cover and below be provided with the pin-and-hole that mutual correspondence and aperture equate, it is characterized in that:
Be respectively equipped with a plurality of equidistant length-adjustment holes on one end of the elastic strip sheet that two chip architectures are identical, the aperture of this length-adjustment holes equates with pin-and-hole on the described fixed cover; A plurality of equidistant length-adjustment holes are set respectively on an end of two elastic strip sheets, can regulate the dynamics that tractive separates, to adapt to the needs of different situations.
The other end of two elastic strip sheets all is inclined upwardly, and is respectively equipped with a coupler body seat at the face of being inclined upwardly;
The end that two elastic strip sheets are provided with a plurality of equidistant length-adjustment holes insert relatively in the fixed cover overlapped and have at least a pair of length-adjustment holes with above the described fixed cover with following on pin-and-hole align;
One latch is inserted by the pin-and-hole above the described fixed cover, a pair of length-adjustment holes of passing two elastic strip sheets successively, and the pin-and-hole below described fixed cover stretches out, and two elastic strip sheets are connected on the described fixed cover;
Two identical coupler bodies of structure are fixedlyed connected with the coupler body seat of two elastic strip sheet the other end by nut respectively.
Adopt two elastic strip sheets and fixed cover to be connected, to realize that need not the assistant assists and tractive separation automatically, is specially adapted to the requirement of field operations treatment.
Further, the other end of its described two elastic strip sheets all acclivitous angle [alpha] be the 100-120 degree.
Further, the identical coupler body of its described two structures is fork formula double hook structure, the equal rounding of coupler body contour edge.Adopt fork formula structure to be conducive to tractive and separate reliably, the equal rounding of coupler body contour edge is conducive to reduce unnecessary damage.
Further,, its described nut is dish shape nut.Adopting dish shape nut, do not need to be equipped with in addition spanner, manually is detachable or fastening coupler body, regulates the coupler body angle.
Further, on described fixed cover, be provided with a bar hole.Whether align in order to the length-adjustment holes of observing two elastic strip sheets.
This utility model is compared with prior art and had the following advantages: the dismounting combination is quick, is easy to carry; Need not the assistant and assist and tractive separation automatically, be specially adapted to the requirement of field operations treatment; Coupler body adopts fork formula structure, and tractive separates reliable, and the equal rounding of coupler body contour edge is conducive to reduce unnecessary damage; The dynamics that tractive separates can be regulated, and regulates easyly, and the scope of application is bigger.
