Abstract
A CT-guided percutaneous transthoracic needle biopsy positioning system comprises a scale and a puncture positioner, wherein the scale is connected with a fixing band; the puncture positioner consists of a chassis, a protractor and a guide rod; the guide rod is mounted on the chassis; the guide rod is provided with the protractor; the chassis is provide with a hole channel; and the scale penetrates the chassis via the hole channel and forms a sliding fit with the puncture positioner. Due to accuracy in positioning, the CT-guided percutaneous transthoracic needle biopsy positioning system reduces the repeating times of punctures, so as to remarkably reduce the occurrence rate of complications.
Description
Technical field
This utility model relates to a kind of CT guiding percutaneous transthoracic needle biopsy navigation system down.
Background technology
There is not commercial or general CT guiding percutaneous transthoracic needle biopsy navigation system down at present.Generally need be under the CT guiding during percutaneous puncture biopsy, many accepted scales are measured points of puncture and physique tag distance, epidermis anesthesia afterwards syringe needle as puncture needle road warp and direction.Its shortcoming is: during tape measure, along with position or respiratory change, have certain error; Epidermis anesthesia back syringe needle is as guiding puncture road warp and adjust puncture needle inserting needle direction, often may occur than large deviation, this is after determining the puncture entry point and inserting needle direction of syringe needle because of CT scan, must extract syringe needle out, point of puncture at former syringe needle penetrates biopsy needle again, its inserting needle direction and angle very accurate (because of syringe needle is extracted).Its consequence is to cause and need repeatedly puncture, even puncture failure, the repeatedly generation that leads to complications easily of repeated localised puncture.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of CT guiding percutaneous transthoracic needle biopsy navigation system down, can accurately carry out the body surface location and guide biopsy needle accurately to penetrate in the pathological changes that need get biopsy.To improve its puncture success rate, reduce the generation of complication.
For solving the problems of the technologies described above, the technical scheme that this utility model is taked is: the CT guiding is the percutaneous transthoracic needle biopsy navigation system down, comprise scale, puncture locator, scale is connected with fixing band, and puncture locator is made up of chassis, protractor, guide rod, guide rod is installed on the chassis, guide rod is provided with protractor, and described chassis is provided with the duct, and the scale passing hole channel passes the chassis and puncture locator is slidingly matched.
Described chassis is provided with rotating shaft, and guide rod is enclosed within the rotating shaft by screw and is fixed on chassis side.
Described fixing band is provided with thread gluing.
Described chassis is provided with graduation mark.
Described scale is the coil chi.
This utility model CT guiding is the percutaneous transthoracic needle biopsy navigation system down, has the body surface scale of fixing band, is fit to almost any position of human body, and puncture point orientation is accurate; The body surface scale is formed by coil chi material, can form any radian.The chassis of puncture locator is provided with graduation mark, can reach localized purpose more accurately.The guiding puncture device is provided with the guide rod of band protractor, can regulate puncture angle accurately, and the success rate of puncture is largely increased.Simultaneously, because accurate positioning has reduced the number of repetition that punctures, significantly reduce the incidence rate of complication from face.The aspiration biopsy, the breast abdominal part in-vivo puncture and intubation drain that also can be used for being grown up also can be used for other position of human body to the percutaneous transthoracic needle biopsy navigation system, as positions such as extremity, pelvic cavity in being used for breast abdominal part body under this utility model CT guiding.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is this utility model scale structure figure;
Fig. 2 is this utility model puncture locator structure chart;
Fig. 3 is this utility model puncture locator side view;
Fig. 4 is this utility model structure chart.
The specific embodiment
The CT guiding is the percutaneous transthoracic needle biopsy navigation system down, comprise scale 1, puncture locator, scale 1 is connected with fixing band 3, puncture locator is made up of chassis 5, protractor 8, guide rod 7, and guide rod 7 is installed on the chassis 5, and guide rod 7 is provided with protractor 8, described chassis 5 is provided with duct 4, and scale 1 passing hole channel 4 passes chassis 5 and is slidingly matched with puncture locator.
Described chassis 5 is provided with rotating shaft 6, and guide rod 7 is enclosed within the rotating shaft 6 by screw and is fixed on 5 sides, chassis.
Implementation step:
The CT scan of a part need to determine the aspect of puncture and the entry point and the inserting needle direction of this aspect on the CT image in advance.Again the CT scan bed is entered this aspect, open positioning light, along the lamp shadow mark line that on body surface, draws.
On the CT image, measure the distance of point of puncture to back spinous process (facial mid point), percutaneous transthoracic needle biopsy navigation system under this utility model CT guiding is fixed in 2cm place, body surface mark line top, according to body surface scale 1 high scale, find out the point of puncture on the body surface mark line.
After sterilization, the local anaesthesia, keep syringe needle in the skin tissue around the point of puncture, make syringe needle parallel, consistent with the puncture section as far as possible with puncture angle.And then this aspect CT scan of row, the position and the direction of understanding syringe needle.If there is certain deviation in syringe needle with the puncture direction, on the CT image, measure its angle [alpha], regulate 0 graduation mark of the protractor 8 on this utility model and anesthetic needle is first causes, re-adjustment guide rod 7 makes it into the α angle.
After extracting the anesthesia syringe needle out, along guide rod 7 directions (must be parallel with the body surface mark line) inserting needle in body, depth of needle is as the criterion (scale is arranged on the biopsy needle) with the CT image measurement degree of depth, just biopsy needle can accurately be penetrated the position of drawing materials through point of puncture (anesthesia syringe needle place), safety, reliable.
