Description
Technical field
This utility model relates to the lower support used of a kind of CT guiding, the guide support in particular accurately punctured under a kind of CT.
Background technology
In recent years, less invasive techniques is fast-developing and universal, and wherein quite a few work is to carry out the puncture of deep tissue target under CT.From under B ultrasonic or the lower puncture of DSA (digital subtraction angiography Digital subtraction angiography) different, the puncture under CT can not be carried out under Real-time and Dynamic observation, often needs repeatedly to adjust, consuming time for a long time, and error is large.Existing technology is divided into following several: 1, complete free-hand puncture, by rule of thumb, after clear and definite body puncture point, estimate about angle and the degree of depth, and iterative method, adjust position and angle by repeatedly taking CT.2, protractor location: the assistant, in patient's foot side, aims at puncture needle with a transparent protractor, joins easy level indicator on some protractors, by this kind of method, adjusts the puncture needle angle on transverse section.3, fixed guide: will with the utensil of inclinometer, be fixed on the CT bed, after adjusting angle, puncture needle enters along chute.4, band plumb line and protractor on puncture needle, after puncture needle tilts, and plumb line formation angle, show numerical value in protractor, thereby regulate the angle of puncture needle.5, laser aiming: laser aid is fixed on the other ground of CT machine, penetrate beam of laser by the angle of setting, piercing needle is fixed on the laser projection place on skin, and the afterbody of puncture needle is placed in the path of laser (allowing laser point drop on the afterbody of puncture needle), slowly advances.
But there are problems in above-mentioned apparatus aspect the accuracy of the convenience of using and location, thus the simplest and the crudest free-hand method often adopted when the patient punctures under CT at present, but free-hand method has following defect:
1, complete free-hand puncture: by experience, lack definite object of reference fully, accuracy and safety are all uncontrollable.
2, protractor location: error is at the 5-10 degree, but needs two people's cooperations, the observer also needs the level of continuous adjustment amount hornwork, in addition, can't guarantee that puncture needle drops in the vertical plane at CT scan place fully.
3, fixed guide: only be adapted to the puncture of single-point, radioactive particle is implanted needs multiple spot puncture simultaneously, and utensil is difficult to accurate movement.
4, band plumb line and protractor on puncture needle: only show and the relative angle of plumb line the skew of uncontrollable puncture needle on sagittal plane.
5, laser aiming: during puncture, due to the pliability of skin histology, skin penetrating point often has a little skew, but as still using Aculeata as the aiming point of laser, can constantly increase error in traveling process, and tissue is had to horizontal damage.
