Description
(1) technical field
The present invention relates to a kind of CT localised puncture device.
(2) background technology
At present, the medical worker sticks row's metal material earlier on the body surface of puncture target when carrying out the operation of CT localised puncture, pass through CT scan, according to the relation of metal material on the scintigram, make point of puncture and puncture angle, then selected point of puncture inserting needle on human body with the puncture target, main operator's experience and the target of technical merit in the imagination of relying on advanced, puncture, error is big, is difficult for successfully, particularly for the target on puncture and the not same CT tangent plane of point of puncture, difficulty is bigger.
(3) summary of the invention
The object of the present invention is to provide a kind of the location can accurately make point of puncture and puncture angle and paracentesis depth by CT, and the CT localised puncture device that the target on the same or not same CT tangent plane all can accurately puncture for point of puncture.
Technical scheme of the present invention is: CT localised puncture device of the present invention comprises a location-plate and an angle measurer, it is characterized in that: be provided with horizontal concrete chute on location-plate, fix a sting device on the chute; Establish a perforated slot on location-plate, angle measurer is placed in the perforated slot, and the axle that passes its center of circle is fixed on the location-plate, and angle measurer is vertical mutually with location-plate.
Sting device of the present invention comprises is with graduated puncture supporter, and a side is established a puncture tube on the puncture supporter, also is provided with a vertical chute on the puncture supporter, and puncture supporter passes chute with location-plate by a screw rod fixedlys connected.
Angle measurer of the present invention comprises a protractor, and the arc limit of protractor is provided with tooth, and the protractor base is marked with scale.
Location-plate of the present invention comprises a base arcuate edge, be embedded with the object of reference that is used for determining point of puncture of row's metal-containing material on it, its side is that straight line is as object of reference, respectively there is a fixing hole location-plate dual-side below, above perforated slot, also establish a fixing lock, can tie down tooth on the protractor arc limit with the stationary positioned plate.
A whole set of instrument of the present invention, except that object of reference 10a was made by metal-containing material, all the other were made by nonmetallic materials.The utilization of can sterilizing repeatedly of positioner of the present invention and angle measurer, sting device be owing to directly contact with puncture needle, easily by patient's humoral pollution, and the genus disposable apparatus.When using the present invention to puncture, patient lies on the CT bed, and this instrument is placed the body surface of puncture target tangent plane, makes location-plate parallel with the CT tangent plane, and fixes with fixing band respectively.After the CT scan, relation according to puncture target and object of reference on the scintigram, make point of puncture, measure the distance of puncture target and point of puncture, measure through puncture impact point and the puncture straight line of point of puncture and the angle between the object of reference 10b on the location-plate, again with the most advanced and sophisticated aligning of puncture tube point of puncture, the angle of adjustment sting device and object of reference 10b equal the to puncture angle of straight line and object of reference 10b, fix sting device, puncture again.To point of puncture when the target of different CT tangent planes punctures, location-plate is placed going up or next intercostal space of puncture target CT tangent plane, and parallel with the CT tangent plane, make angle measurer plane cutting puncture target.Fixing band fixes location-plate and angle measurer respectively.Point of puncture is chosen in the position of as far as possible close angle measurer.The most advanced and sophisticated point of puncture of aiming at of puncture tube makes sting device parallel with angle measurer, fixes sting device.Angle according to body surface and CT tangent plane, the vertical dimension of point of puncture tangent plane and puncture target, and the distance of puncture impact point intersection point near the body surface angle measurer to puncture tube plane and puncture target tangent plane, calculate the puncture angle and the degree of depth, location-plate is done corresponding the adjustment in the angle of angle measurer upper deflecting, reserve location-plate with fixing locking, puncture again.
By the CT localised puncture device that such scheme is made, have simple in structurely, easy to operate, can accurately make point of puncture and the puncture angle and the degree of depth, the characteristics such as all can accurately puncture of the target for point of puncture on the same or not same CT tangent plane.
(4) description of drawings and embodiment
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention, and Fig. 2 is the structural representation of angle measurer of the present invention.
