Background technology
Hospital usually need retract operative incision with surgery tractor in department of general surgery's operation, to obtain openr operating field.And at present, mostly the employed drag hook of hospital is single hook structure, and width is limited, if will fully expose operating field; Need a plurality of drag hooks to draw jointly, and need the assistant to assist operation, overlong time; The assistant can feel that arm is weak, and influence retracts effect, has improved the risk of operation.
Summary of the invention
This utility model technical problem to be solved is the deficiency that overcomes above-mentioned prior art, provide a kind of simple in structure, be convenient to operation, do not need department of general surgery of the fixed hospital of assistant's tractive operation to use drag hook.
This utility model solves the technical scheme that its technical problem adopted: drag hook is used in the operation of department of general surgery of hospital; Mainly be made up of U-shaped drag hook arm, it is characterized in that: have slideway on two straight-arms of U-shaped drag hook arm, slideway is provided with screw rod; Be fixedly connected through the compression spring between the two screw rods; There is nut in the said screw rod outside, and said screw rod can slide in slideway, and U-shaped drag hook arm opening one end is fixedly connected with drag hook.
After the operation of department of general surgery of this utility model hospital is adopted said structure with drag hook; Its beneficial effect is: can regulate the distance between two drag hook arms by operating field as required; Reach the purpose of distance between the indirect regulation drag hook; When needing the tractive operative incision, under the effect of compression spring, do not need artificial tractive to fix, saved manpower.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
Fig. 1 is the structural representation of this utility model.
Among the figure 1, U-shaped drag hook arm, 2, slideway, 3, screw rod, 4, nut, 5, the compression spring, 6, drag hook.
The specific embodiment
As can be seen from Figure 1, drag hook is used in the operation of department of general surgery of this utility model hospital, mainly is made up of U-shaped drag hook arm 1; It is characterized in that: have slideway 2 on two straight-arms of U-shaped drag hook arm 1; Slideway 2 is provided with screw rod 3, is fixedly connected through compression spring 5 between the two screw rods 3, and there is nut 4 in said screw rod 3 outsides; Said screw rod 3 can slide in slideway 2, and U-shaped drag hook arm 1 opening one end is fixedly connected with drag hook 6.
As shown in Figure 1, this practical U-shaped drag hook arm 1 general rigid plastics or rigid material of adopting is made, during operation; According to needed operating field, tighten or the nut 4 of loose ends, just can dwindle and enlarge the spacing of two drag hooks 6; The position that screw rod 3 arrival of both sides of also can sliding as required need, two drag hook arms 1 the effect of compression spring 5 down with the elastic force effect of U-shaped drag hook arm own under, outer all the time; Like this, two drag hooks are placed in the operative incision just can operative incision be strutted, to enlarge operating field; If operative incision is less, also available one of them drag hook enlarges operating field under assistant's assistance.
This utility model is simple in structure, be convenient to operation, do not need assistant's tractive to fix, and reduced the labor intensity of surgical staff, saved manpower.Can be widely used in the hospital in department of general surgery's operation.
