Abstract
The utility model provides a device for puncture positioning under the real-time guide of CT (computed tomography). A lifting sliding rail capable of longitudinally sliding is arranged on a sliding rail seat which can be fixedly arranged on a CT bed plate, and is provided with a lifting-adjustable transverse sliding rail; a three-dimensional cradle head capable of transversely sliding is arranged on the transverse sliding rail; a puncture module is arranged at the outer end of the three-dimensional cradle head; a biaxial digital display angle gauge is arranged on the puncture module. When the device is used, the puncture module can be calibrated and aligned with a puncture part of a patient to regulate the angle of the puncture module by virtue of integral matched sliding adjustment, and a puncture needle directly reaches a focus part of the patient in a puncturing way through a corresponding needle hole in the puncture module. The device can move synchronously with the CT bed plate, and the fixation of the puncture needle and repeated real-time verification monitoring during CT verification are ensured; the puncture accuracy can be greatly improved, and the one-time success rate can be increased to be over 95 percent.
Description
Technical field
This utility model relates to the apparatus using when a kind of hospital adopts CT scan puncture for patient, specifically puncture positioning device under a kind of CT guiding in real time.
Background technology
When hospital extracts pathology sample for patient uses CT scan to puncture, to to lesions position, position and implement puncture by scanning, traditional method is the in the situation that of CT scan, doctor holds inserting needle direction with medical skill and experience with palm, because inserting needle is to implement by artificial mode, in addition the difference of medical skill and experience causes being difficult to once be punctured to accurately correct position, cause there will be repeated multiple times adjustment inserting needle, the phenomenon that CT scan is verified repeatedly, this puncture that cannot accurately put in place, directly increased patient's misery, and cause operating time long, exist CT scan checking to need medical personnel to hold up pin simultaneously, the problems such as poor repeatability.
Summary of the invention
The purpose of this utility model is to solve the problems of above-mentioned existence, and puncture positioning device under a kind of CT guiding in real time is provided, have easy to operate, accurate feature punctures.
This utility model comprises the three-dimensional The Cloud Terrace of this device, the technical scheme adopting is: can be fixed on slide track seat on CT bed board be equipped with one can straight skidding lifting sliding rail, lifting sliding rail is equipped with the horizontal slide rail that liftable regulates, on horizontal slide rail, be provided with can horizontal sliding three-dimensional The Cloud Terrace, there is a piercing module outer end of this three-dimensional The Cloud Terrace.On piercing module, there is a twin shaft digital display angle instrument.
In technique scheme: described slide track seat is connected and fixed by fixation clamp and CT bed board.
Lifting sliding rail is arranged on slide track seat by the take-up housing of bottom.
Three-dimensional The Cloud Terrace tail end adopts slide block to be connected with horizontal slide rail, the Sliding Structures that formation universal adjustment frame can lateral adjustments.
This utility model passes through technique scheme, can be up and down and horizontal sliding owing to having adopted, and the population structure of the various angles of scalable, and in overall structure, be provided with a piercing module, while using after installing, can allow single unit system under the prerequisite of CT scan, by the adjusting of upper and lower and left and right and angle, allow corresponding pin hole on piercing module aim at patient's lesions position, adjust puncture angle, can by the corresponding pin hole on piercing module, directly be inserted syringe needle and puncture, can reach thus the effect that degree of accuracy and success rate greatly improve.Overall structure can be synchronized with the movement with CT bed board, can adjust rapidly various accurate angles, and can show easily the level of various angles, and during CT checking, fixedly puncture needle can be realized real-time monitoring.Through making sample experiment, the mean error of puncture narrows down to 4mm by former 34mm, by 20 patients are tried out, one-time success rate brings up to 95% by former 40%, and operating time shortened in 10 minutes by original 30 minutes, simultaneously, because operating time is short, the number of times of CT scan, also by average reducing to for 6.5 times 2.05 times, allows the suffered amount of radiation of patient drop to 15mSv by 65mSv, reduced accordingly the suffered amount of radiation of surgical staff, by former 20mSv, be down to 3mSv simultaneously.This utility model efficiently solves the problems that exist when present hospital is used CT to implement puncture operation for patient, has the distinguishing feature that can improve accuracy and success rate.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is this utility model structural representation.
In figure: 1, slide track seat, 2, fixation clamp, 3, take-up housing, 4, lifting sliding rail, 5, horizontal slide rail, 6, slide block, 7, three-dimensional The Cloud Terrace, 8, piercing module, 9, twin shaft digital display angle instrument, 10, CT bed board.
The specific embodiment
Shown in Fig. 1: can be fixed on slide track seat 1 on CT bed board 9 be equipped with one can straight skidding lifting sliding rail 4, lifting sliding rail 4 is equipped with the horizontal slide rail 5 that liftable regulates, on horizontal slide rail 5, be provided with can horizontal sliding three-dimensional The Cloud Terrace 7, there is a piercing module 8 outer end of this three-dimensional The Cloud Terrace 7.Slide track seat 1 is connected and fixed by fixation clamp 2 and CT bed board 9.Lifting sliding rail 4 is arranged on slide track seat 1 by the take-up housing 3 of bottom.Three-dimensional The Cloud Terrace 7 tail ends adopt slide blocks 6 to be connected with horizontal slide rail 5, form the Sliding Structures that three-dimensional The Cloud Terrace 7 can lateral adjustments.
Described piercing module 8 can adopt rigid plastics to make, during making, and the pin hole of a plurality of different pore sizes that distribute on block.Piercing module 8 should have certain thickness, so that syringe needle can better be located, during use, can on piercing module 8, place the device of calibrated horizontal state and puncture needle angle, can better meet requirements of operation.Meanwhile, side or the afterbody that can allow integral body be fixed on CT bed board 9 by slide track seat 1 be used, and specifically can be decided according to the actual requirements.In using state, this device can be with CT bed board synchronizing moving, fixing puncture needle in the time of can allowing thus CT checking, and operation technique is more convenient.
The related three-dimensional The Cloud Terrace 7 of this utility model can select photographic equipment on market to be configured for adjusting the three-dimensional The Cloud Terrace 7 of camera angle, this three-dimensional The Cloud Terrace 7 has gear type and two kinds of angle adjustment mechanism of multi-directional ball, what in this utility model accompanying drawing, provide is gear type structure, also can select the three-dimensional The Cloud Terrace 7 of universal ball structure during actual production.
