Background technology
CT guiding Transthoracic Biopsy is a kind of common method of Diagnosis of Pulmonary Diseases and treatment.Making a definite diagnosis of some pulmonary lesions needs to utilize puncture needle to carry out sampling biopsy to affected area, just can reach diagnostic purpose.At present, medical worker is when carrying out the operation of CT Guided Percutaneous Biopsies for Lung Lesions art, used metal material as object of reference at the body surface of puncture target before this, by the scanning of CT, according to the relation of pulmonary lesions on scintigram and metal material, thus determine point of puncture and puncture angle, and then free-handly to puncture, but this puncture is mainly punctured with technical merit with the experience sensation of medical worker, in art, puncture angle is wayward, error is large, easily cause puncture inaccurate, so often puncture certain depth need CT scan observe puncture needle position and needle track around pulmonary condition to guarantee that operation safety carries out, therefore need repeatedly to select adjustment puncture angle and paracentesis depth, operating time is long, add the risk of operation, need to improve.
Summary of the invention
The purpose of this utility model is to provide a kind of utility model CT and guides Poitioning device for pneumocentesis, make objectively select correct puncture angle and paracentesis depth during CT guided percutaneous transthoracic lung biopsy art, and fixing puncture angle, quick, accurate, stable the carrying out of biopsy needle guide is punctured, reduce operating time, reduce operation risk, reduce the incidence rate of complication, have simple and practical, angle orientation accurately, puncture feature efficiently.
In order to solve the problem existing for background technology, this utility model is by the following technical solutions: described CT guides Poitioning device for pneumocentesis to comprise puncture needle 1, square motion arm 2, underframe disk 3, plastic nut 4, protractor 5, guide sheath pipe 6 and tinsel screen 7, described tinsel screen 7 is for determining the object of reference of point of puncture, and form by six roots of sensation fine wire is arranged in parallel, tinsel is spaced apart 10mm, and six roots of sensation tinsel is fixed into rectangle by two narrow adhesive tapes of transparent plastic, described underframe disk 3 is circular base plate, it is a soft plastic material, cross pattern is made in the circle of chassis, four head ends of cross are defined as A end, B end, C end and D end respectively, extend the plastic tape that four available stickers are fixing in this cross direction, cross is drawn has two orthogonal centrages, two vertical center line intersections, have a small sircle hole, this is the hole that puncture needle 1 enters, described protractor 5 tow sides are provided with the angle index instruction of 0 ~ 180 degree, are fixedly connected with on circumference with underframe disk, and vertical with underframe disk, and protractor 90 degree of calibration points are projected on Gacrux bar centrage, described square motion arm 2 is a cuboid-type device, two vertical planes and a horizontal plane, without base, two vertical plane sides are flexibly connected with protractor 5 centre point place, be positioned at the A end of underframe disk cross, opposite side is held with the C of underframe disk 3 cross and is flexibly connected, a plastic nut 4 is equipped with in junction, square motion arm 2 can be fixed with plastic nut 4 during puncture, square motion arm 2 horizontal plane and two vertical planes are all carved with middle separated time, horizontal plane there is a central small hole, when square motion arm 2 and chassis cross horizontal plane, the middle separated time of square motion arm 2 liang of vertical planes and horizontal plane and 90 degree of graduation marks of protractor 5 are all on same upright plane, and square motion arm 2 horizontal plane central small hole be projected in the central small sircle hole place of underframe disk 3, the central small hole place of square motion arm 2 horizontal plane is provided with guiding puncture sheath pipe 6, so that puncture needle 1 passes through, package unit structure, except tinsel screen 7 and puncture needle 1, is all made by non-metallic plastic material.
This utility model compared with the prior art compared with advantage be: scan red line in the operation of CT machine and to have good positioning focus puncture aspect, the circular base plate that soft plastic material is made should make B when patient body-surface is fixed, D holds centrage parallel with red line and overlapping, behind location, circular base plate can bend according to body surface situation and be fixed on patient body-surface stably, and the protractor on localizer can not be out of shape, when choosing puncture angle, when the vertical plane that this device square motion arm is connected with protractor slides on protractor face all the time with protractor face near, by in vertical plane during separated time selected angle, selection for angle is very clear, can selected angle accurately, thus the error caused because of vision difference and distortion when avoiding arcuate movement arm to choose angle, fix with plastic nut 4 after choosing puncture angle, this device set angle is clear accurately, quick, and not easily change after angle is fixing, operating time shortens, and reduces operation risk.
