Description
Technical field
The present invention relates to medical auxiliary apparatus technical field more particularly to a kind of lung puncture angle controls based on CT guidance
Device and its angle control method processed.
Background technique
CT guided percutaneous transthoracic biopsy art because it is traumatic it is small, using simple and efficient, approved by numerous medical personnels and connect
It receives, and it is safe and reliable to be widely considered to be comparison.Such technology can provide histocytology for disease and check sample, can also carry out
The local treatment of lesion.And the accuracy rate and complication punctured is always two big projects of clinical research.Best entry point selection
Afterwards, the accuracy rate of puncture is determined by three entry point, depth of needle and angle factors.Only correct and careful selection into
After pin mark, puncture angle and lesion depth, the disposable success of puncture just can guarantee.During lung puncture, in order to true
The precision punctured is protected, multiple CT scan need to be carried out.Therefore the radiological dose that patient receives increases.There are relevant report, radiation agent
Amount is higher, and the disease incidence of cancer is caused to be increased.
For this purpose, many scholars have developed corresponding positioning device, such as: entry point can be selected with fence locator.Into
Needle depth can accurately be measured by the software that CT machine carries.But needle angle is then mainly determined by the experience for puncturing doctor.Mesh
Preceding navigation type product is too expensive, and most of basic hospital is not likely to consider purchase, so developing economic, easy, practical angle
Degree control device can bring convenience to operation.When especially puncturing to smaller or deeper lesion, needle angle slightly has
Deviation punctures after adjusting needle angle again it is necessary to which puncture needle is retracted entry point.The wound that can cause normal tissue is punctured repeatedly
Wound, leads to the appearance of various complication, such as infection, pneumothorax, intrapulmonary bleeding, serious person lethal can die.
Summary of the invention
The present invention is to solve the above problem in the prior art, proposes a kind of lung puncture angle control based on CT guidance
Device and its angle control method.
To achieve the above object, the invention adopts the following technical scheme:
The first aspect of the invention is to provide a kind of lung puncture angle controller based on CT guidance, including bottom
Seat and enters needle guide seat at angle ring；Wherein:

Needle outlet is pierced by.
Further, the rear and front end of the pedestal, which is respectively articulated with, is provided with turnover tabletting.
Further, it is opened up on the bottom end face of the pedestal fluted.
Further, the pedestal is rectangle structure, and flexible material is used to be made.
Further, the needle outlet and two hinge holes are located in same horizontal line.
Further, semicircle guide groove is offered on the semicircular structure plate of the angle ring.
It is further preferred that it is described enter needle guide seat inner sidewall be provided with and the semicircle guide groove limited block, institute
Limited block is stated slidably to be set in the semicircle guide groove.
Further more preferably, the limited block uses soft rubber material, and matches with the semicircle guide groove interference
It closes.
Further, it is described enter the fan-shaped structure in needle guide seat side.
Further, it is described enter needle guide seat side wall be provided with clamping screw.
The second aspect of the invention is to provide a kind of lung puncture angle based on CT guidance such as the control device
Control method includes the following steps:
Step 1, under the premise of patient comfort, stablizing, distance with lesion away from body surface is most short for principle, chooses corresponding
It lies on the back, the positions such as prostrate, horizontally-inclined；
Step 2, fence locator is pasted in focal area, carries out positioning scanning；Take lesion maximum gauge and avoid bone,
Blood vessel and lesion necrotic area；
Step 3, it after entry point selection, is marked on the skin, while carrying software with CT and calculating paracentesis depth；
Step 4, after local skin disinfection, bedding hole towel, infiltration anesthesia removes hole towel；With disinfection adhesive tape by the recessed of pedestal
Slot is fixed on patient skin along CT laser, repaves hole towel；
Step 5, the setting angle ring on pedestal, and it is fixed into needle guide seat by required angle, make to be pointing directly at into pin hole
Lesion center；
Step 6, examination couch is retracted puncture level to be scanned, can shows and enters pin hole into needle guide seat；
Step 7, it is punctured using puncture needle, after reaching lesion, then row CT scan, it determines after puncturing successfully, with puncture
Needle takes corresponding pathological tissues to carry out cytohistology inspection；
Step 8, terminate to puncture, gently retract puncture needle, remove angle controller.
The present invention by adopting the above technical scheme, compared with prior art, has the following technical effect that
The present invention is based on the lung puncture angle controllers and its angle control method of CT guidance, and needle will be entered before puncture
It is accurate that hole adjusts under CT guidance, makes to be pointing directly at lesion center into pin hole；The direction of inserting needle and angle are adjustable when puncture
The track limitation into needle device shaft is saved, the center of lesion can only be directly entered along the direction that shaft is guided.It therefore can be effective
Control needle angle makes to puncture disposable success by control errors within 0.5cm.Puncture rate repeatedly is reduced, is reduced because puncturing
Bring tissue trauma and complication.
