Description
Technical field
The present invention relates to the aseptic sursery medical apparatus and instruments, be specifically related to be applicable to the soft tissue debridement self-retractor of firearm injury.
Background technology
The experience of all previous war treatment of war wound shows, all must in the shortest time, promptly implement debridement surgical by the soft tissue injury that firearm causes, promptly remove the interior foreign body of open wound, the tissue of excision necrosis, inactivation or severe contamination, correct blood vessel, the nerve that damages of handling with operating method.The debridement principle of soft tissue firearm injury is: debridement was more early good more after hindered (1); (2) strict sterile working; (3) otch will reach greatly, and debridement is wanted thoroughly; (4) wound is not made primary suture after the debridement.Although soft tissue firearm injury debridement is through a large amount of for many years research and practice, time limit of hindering the back debridement, principle, shock, damage control, postoperative care etc. all there have been more deep understanding, be a kind of surgical procedures of conventional ripening.But for the operating theater instruments and the equipment of debridement and wound surface processing, the research and development of this respect are still very weak.The medical worker need draw back the soft tissue of otch both sides with drag hook when undergoing surgery, to expose surgical field of view, be convenient to operation technique.The specificity that existing medical drag hook has is too strong, and as goitre retractor, the scope of application is narrow; The operation inconvenience that has needs assistant's coordinated; The structure that has is complicated, and volume is big, and inconvenience is carried." a kind of Minimally Invasive Surgery drag hook " of CN 201996599U bulletin, a kind of exactly drag hook that is applicable to the orthopaedics Minimally Invasive Surgery, though can carry out tractive to the otch soft tissue effectively separates, the elastic construction of handle makes medical worker conversion assurance direction and angle easily, solve a difficult problem of in the orthopaedics Minimally Invasive Surgery otch soft tissue tractive being separated inconvenience, but be not suitable for the requirement of field operations treatment.Therefore, need exploitation to be applicable to the soft tissue debridement drag hook of field operations treatment.
Summary of the invention
The purpose of this invention is to provide a kind of soft tissue debridement self-retractor, it is simple for structure, be easy to carry, can carry out adaptability according to the length of debridement otch prolongs or shortens, appear wound surface better, help the debridement surgical operation, combination is quick, regulate easy, the scope of application is big, and tractive separates reliable, and need not assistant's assistance.
Soft tissue debridement self-retractor of the present invention 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 isolating dynamics of tractive, 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 on 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, all acclivitous angle [alpha] in the other end of its described two elastic strip sheets is the 100-120 degree.
Further, the identical coupler body of its described two structures is a fork formula double hook structure, the equal rounding of coupler body contour edge.Adopt fork formula structure to help tractive and separate reliably, the equal rounding of coupler body contour edge helps reducing unnecessary damage.
Further,, its described nut is a 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.
The present invention compares with prior art and has 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 helps reducing unnecessary damage; The isolating dynamics of tractive can be regulated, and regulates easyly, and the scope of application is bigger.
