A kind of disposable thyroid needle device positioning deviceTechnical field
The present invention relates to medical domains, and in particular to a kind of disposable thyroid needle device positioning device.
Background technique
Thyroid needle art is a kind of method for diagnosing Tubercle thyroid.Thyroid fine needle aspiration biopsy is existingHaving determined as the very high diagnostic method of accuracy.In traditional thyroid needle art, need using disposable first shapeGland puncture device punctures acquisition Pathologic specimen to thyroid nodule and diagnoses, and needs specifically to wear using Ultrasonic-B probe determinationPierce position.Implement whole biopsy using Ultrasonic-B probe and disposable puncture device and sample operation, the disposable puncture device of use is moreIt for syringe, is entered using the syringe needle of syringe and punctures sample position, then extract a certain amount of thyroid nodule detection body.But in this operation, haves the defects that certain, specific manifestation are as follows: firstly, needing doctor that B ultrasound is cooperated to visit in integrated operationHead is implemented to puncture operation, and general doctor one holds Ultrasonic-B probe, and the other hand implements puncture procedure operation, once it is determined that puncturing position wellWhen setting with angle, it is necessary to accurately implement needle thorn operation and needs stable operating syringe after puncture angle position determines, andGuarantee position and angle accuracy, traditional manual mode of operation be easy puncture enter when there is a certain error, causeOperation is punctured again, gives patient's bring certain pain；Secondly, during puncturing implementation, being needed in traditional operationIt wants Ultrasonic-B probe to be constantly in working condition, increases the operation difficulty of medical staff, once probe positions are mobile, just will affectEffect is punctured, leads to the puncture position image blur having been found that, influences the careful operation of medical staff.
The patent that China Patent No. is 2016211430953, discloses a kind of Thyroid puncture needle, including puncture needle rifle,Punch block and needle, are coupled puncture needle rifle, needle connecting puncture needle rifle above punch block, and the first hinged seat is installed in punch block one end, and firstHinged seat connects one end of hound, and the other end of hound connects the second hinged seat, and the second hinged seat is mounted on clip oneThe hand-held part of side, clip and Ultrasonic-B probe cooperates, and for clip clamping fixed in the hand-held part of Ultrasonic-B probe, the installation of clip two sides is verticalBracket, the bottom of bracket is fixedly connected with clip, and cradle top installs guide pad, is close to Ultrasonic-B probe on the inside of guide pad, leadsU-shaped connection frame is installed to block internal engagement, the inside middle portion of U-shaped connection frame and the guide groove of guide pad cooperate, U-shaped connection frameBoth ends end it is hinged with punch block respectively.
The patent is a kind of puncture needle, whole to use as a kind of puncture product, although giving the regulatory function of needle,It is when specific operation, adjusting for needle can only be implemented to adjust in the angle position of restriction, can not achieve the fixation of needle after adjustmentAnd stable puncture procedure, it is careless slightly, the variation of point of puncture is resulted in, implements the adjusting of angle again in subcutaneous puncture,Difficulty is very big, needs hurried puncture toward contact, thus the prior art have the defects that it is certain.
Therefore, it is simple to produce a kind of structure, easy to operate, work and operational efficiency are high, and accurate positioning is firm, puncture procedureReliable and stable, operation is accurate, easy to control, reduces operation difficulty, reduces patient suffering, primary to complete, and realizes angle and longitudinal directionThe limit of depth adjusts, and stablizes support when providing puncture, efficient and convenient disposable thyroid needle device positioning device hasExtensive market prospects.
