Description
Technical field:
This utility model relates to medical apparatus and instruments, particularly a kind of operation on vessels of heart sternal retractor.
Background technology:
When the treatment operation of carrying out cardiovascular disease, need cut breastbone and just can carry out next step operation.The for example operation of pericardium excision, need to cut otch in the breastbone center, after cutting breastbone, retractor retracts breastbone, answer free breastbone posterior synechiae limit, limit slowly to retract breastbone, prevent to increase the weight of the pericardium pressurized, when stripping off, tear the one or both sides pleura, put chest drainage, pericardium constriction chance takes place once again to reduce.This otch is to the exposure good visual effect of both sides ventricle and superior and inferior vena cava, little to the pulmonary function influence.
And the sternal retractor of present stage mostly is by rack-plate, and lever arm and fixed arm are formed.Its in use, rack-plate is subjected to the extruding force from a plurality of directions, and is easily deformable, this just causes the slip of lever arm not smooth, and retractor to retract the retrosternal visual field little, these all are unfavorable for doctor's surgical work.Therefore, press for a kind of simple in structurely, easy to use, lever arm can be free to slide or lock, and the big sternal retractor of surgical field of view.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, provides a kind of simple in structure, easy to use, and lever arm can be free to slide or lock, and the big operation on vessels of heart sternal retractor of surgical field of view.
To achieve these goals, this utility model provides a kind of operation on vessels of heart sternal retractor, wherein, comprise rack-plate, fixed arm and the lever arm that can slide along rack-plate, it is characterized in that an end of described lever arm is provided with sliding seat, the other end is provided with machine leader; Described rack-plate is provided with slip teeth, and described fixed arm is provided with machine leader, is solidly connected between described fixed arm and the described rack-plate.
Described sliding seat is provided with slip runner and rocking handle, and described rocking handle is provided with spacing lock, and described slip runner is meshed with slip teeth on the described rack-plate, is rotatably connected together with bolt between described rocking handle, described slip runner and the described sliding seat.
Described fixed arm and described lever arm are provided with machine leader insertion groove and machine leader set bolt, described machine leader is provided with hook and machine leader fixing head, described machine leader fixing head is provided with the machine leader fixing hole, plugs together between described machine leader fixing head and the described machine leader insertion groove to be connected.
Screw by described machine leader set bolt between described lever arm and the described machine leader and link together, screw by described machine leader set bolt between described fixed arm and the described machine leader and link together.
The outstanding advantage of this utility model is: simple in structure, easy to use, lever arm can be free to slide or lock, and after retracting breastbone, doctor's surgical field of view is big.
