The technical scheme adopted for realizing the purpose of this utility model is: a kind of CT puncture guide-localization instrument, comprise location-plate and the door font support being arranged on location-plate both sides, described door font support is slidably connected by the montant of its both sides and described location-plate both sides, the cross bar of described door font support is provided with slide along described cross bar and the plumbing bar that self can horizontally rotate, described plumbing bar lower end is provided with graduated disc and puncture conduit, described puncture conduit is flexibly connected with described plumbing bar by rotating shaft, and described puncture conduit comprises the inner and outer tubes be threaded.
Described location-plate both sides are provided with slide rail, and the montant lower end of described door font support both sides is provided with the chute matched with described slide rail, and described chute is provided with retaining mechanism.
Described retaining mechanism is the swivel bolt be threaded with described chute through described chute side.
Described location-plate both sides and described cross bar arrange graduation mark.
Described puncture conduit arranges centre of location line.
Described cross bar is provided with the groove along cross bar direction, described plumbing bar is arranged on described cross bar by walking mechanism, described walking mechanism comprises the housing be placed through on described cross bar and the road wheel be arranged in described housing, and described road wheel is arranged in described groove.
Arrange movable motor and electric rotating machine in described housing, described road wheel is connected with the rotor of described movable motor by the rotating shaft being arranged at road wheel center, and described plumbing bar top is connected by the rotor of rotating shaft with described electric rotating machine.
Described plumbing bar lower end is provided with the electric rotating machine of rotating shaft and described puncture tubes connection.
Described movable motor and described electric rotating machine all adopt motor.
CT of the present utility model punctures guide-localization instrument by arranging location-plate, door font support and plumbing bar, thus have effectively achieved the three-dimensional fix of puncture conduit, and by graduated disc and rotating shaft, have effectively achieved the adjustment of puncture angle, the further realization puncture orientation of conduit and the accurate location of point of puncture, be convenient to adjust to best puncture angle, convenient puncture; Further, puncture conduit adopts the inner and outer tubes structure be threaded, and is very easy to the fine setting of paracentesis depth, puncture is accurately put in place, drastically increase the accuracy of puncture.Location-plate both sides and cross bar arrange graduation mark, and make location more accurate, convenient, degree of controllability is higher; Puncture conduit arranges centre of location line, improves the angle controllability between puncture conduit and graduated disc, make angle adjustment more accurately, accurately; Location and angle adjustment is realized by movable motor and electric rotating machine, Automated condtrol can be realized by computer, simple and efficient, accuracy is higher, and adopt motor, controllability is stronger, drastically increases localised puncture point and puncture angle precision and function rate.
