Description
Technical field
The present invention relates to aseptic sursery medical apparatus and instruments, be specifically related to the soft tissue debridement self-retractor being applicable to firearm injury.
Background technology
The experience of all previous war treatment of war wound shows, the soft tissue injury caused by firearm all promptly must implement debridement surgical within the shortest time, namely method surgically removes the foreign body in open wound, and excision is downright bad, inactivation or the tissue of severe contamination, blood vessel, the nerve of correct process damage.The debridement principle of soft tissue firearm injury is: after (1) wound, debridement is more early better; (2) strict aseptic technique; (3) otch will reach greatly, and debridement is wanted thoroughly; (4) after debridement, wound does not make primary suture.Although soft tissue firearm injury debridement is through research and practices a large amount of for many years, having had more deep understanding to the time limit, principle, shock, damage control, postoperative care etc. of debridement after wound, has been a kind of surgical procedures of conventional ripening.But for operating theater instruments and the equipment of debridement and Wound treatment, the research and development of this respect are still very weak.Medical worker, when performing the operation, needs the soft tissue pulling open otch both sides with drag hook, to expose surgical field of view, is 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; Some operation inconvenience, needs assistant's coordinated; Some structures are more complicated, and volume is large, not Portable belt." a kind of Minimally Invasive Surgery drag hook " that CN 201996599U announces, a kind of exactly drag hook being applicable to orthopaedics Minimally Invasive Surgery, although effectively tractive separation can be carried out to otch soft tissue, the elastic construction of handle makes medical worker convert easily and holds direction and angle, solve the difficult problem in orthopaedics Minimally Invasive Surgery, otch soft tissue tractive being separated to inconvenience, but be not suitable for the requirement of field operations treatment.Therefore, exploitation is needed to be applicable to the soft tissue debridement drag hook of field operations treatment.
Summary of the invention
The object of this invention is to provide a kind of soft tissue debridement self-retractor, it is simple for structure, be easy to carry, adaptability prolongation or shortening can be carried out according to the length of debridement otch, appear wound surface better, be conducive to debridement surgical operation, combination is quick, regulate easy, the scope of application is large, and tractive is separated reliable, and without the need to assistant.
Soft tissue debridement self-retractor of the present invention, comprises the fixed cover that section is rectangular, on this fixed cover and below be provided with the mutually corresponding and pin-and-hole that aperture is equal, it is characterized in that:
One end of the elastic strip sheet that two chip architectures are identical is respectively equipped with multiple equidistant length-adjustment holes, and the aperture of this length-adjustment holes is equal with the pin-and-hole on described fixed cover; An end of two panels elastic strip sheet arranges multiple equidistant length-adjustment holes respectively, the dynamics that tractive is separated can be regulated, to adapt to the needs of different situations.
The other end of two panels elastic strip sheet is all inclined upwardly, and on the face of being inclined upwardly, be respectively equipped with a coupler body seat;
The end that two panels elastic strip sheet is provided with multiple equidistant length-adjustment holes relatively insert overlapped in fixed cover and have at least a pair length-adjustment holes with above described fixed cover and the pin-and-hole gone up below align;
One latch is inserted by the pin-and-hole above described fixed cover, successively through a pair length-adjustment holes of two panels elastic strip sheet, stretches out, be connected on described fixed cover by two panels elastic strip sheet from the pin-and-hole below described fixed cover;
The coupler body that two structures are identical is fixedly connected with respectively by the coupler body seat of nut with two panels elastic strip sheet the other end.
Adopt two panels elastic strip sheet and fixed cover to be connected, be separated to realize the automatic pull without the need to assistant, be specially adapted to the requirement of field operations treatment.
Further, described in it, all acclivitous angle [alpha] in the other end of two panels elastic strip sheet is 100-120 degree.
Further, the coupler body that two structures described in it are identical is fork formula double hook structure, the equal rounding of coupler body contour edge.Adopting fork formula structure to be conducive to tractive is separated reliable, and the equal rounding of coupler body contour edge is conducive to reducing unnecessary damage.
Further, nut described in it is dish shape nut.Adopt dish shape nut, do not need to be equipped with spanner in addition, be manually detachable or fastening coupler body, regulate coupler body angle.
Further, on described fixed cover, a bar hole is provided with.Whether the length-adjustment holes in order to observe two panels elastic strip sheet aligns.
Compared to the prior art, the present invention has the following advantages: dismountable is quick, is easy to carry; Without the need to assistant, automatic pull is separated, and is specially adapted to the requirement of field operations treatment; Coupler body adopts fork formula structure, and tractive is separated reliable, and the equal rounding of coupler body contour edge is conducive to reducing unnecessary damage; The dynamics that tractive is separated can regulate, and regulates easy, and the scope of application is larger.
