System shows, is the step can not ignore.
Current aspiration biopsy operation, as lung biopsy is performed the operation, is the needle point being obtained biopsy probe by repeatedly CT scan
With lesions position relation, thus guided puncture.CT Guided Percutaneous Transthoracic Needle Aspiration Biopsy art as the diagnostic method of a kind of Wicresoft,
There is the advantages such as resolution height, registration, be the important means of Diagnosis of Chest Diseases and Differential Diagnosis.But, behaviour at present
Repeatedly CT scan and repeatedly enter pin during work, makes doctor patient by a large amount of radiation injuries, and pneumothorax can occur and go out
The complication such as blood.The long-time use of CT equipment too increases operation cost, and has launched pulmonary surgery at civilian hospital
Limit.
Through finding the literature search of prior art, " ultra low-volume CT and CTP guides grinding of lung bioplsy to the paper of Liu Yang
Study carefully " the adjustment CT scan parameter mentioned in a literary composition is with the method reducing radiation dose.The method makes aspiration biopsy radiation dose show
Write and reduce, but puncture positive rate, complication rate etc. and there is no bigger improvement, and the CT hold facility time cannot be reduced and enter pin time
Number.
Utility model content
The purpose of this utility model there are provided a kind of aspiration biopsy probe with surgical navigational function, can be real-time
Obtain probe location and angle information.
For solving above-mentioned technical problem, this utility model is achieved through the following technical solutions:
A kind of coaxial puncture needle with surgical navigational function, it supports the use with soft tissue biopsy needle/rifle, including outside

As preferably, described collar supports structure is the support round platform of hollow, and described support round platform is set in puncture set
Slide on pipe and location, it is to avoid puncture casing obliquity effects data accuracy.
As preferably, the data line outside described puncture needle tubing is provided with pyrocondensation tube layer, for data line
Play a protective role.
As preferably, described position sensor is six dimensional sensor.
As preferably, described position sensor distance needle point 5-6mm, and the distance of position sensor and needle point pass through be
System carries throw and records.
Principle of the present utility model is, the data line of position sensor passes through magnetic navigation instrument joint and the magnetic conductance of tail end
Boat instrument carries out the spatial registration of operation guiding system and patient after being connected；The position of system reading position sensor return, angle
Degree information, combining target dot information and patient's physiological characteristics, be calculated navigation scheme；By the information of real time record, from away from
Walk-off angle degree two aspect instructs doctor to enter pin；After puncturing into pin, support round platform is close to patient skin, prevents coaxial puncture needle from inclining
Tiltedly.After knub position is completed location, needle tubing will be punctured and extract out, then coordinate the navigation scheme of magnetic navigation instrument by biopsy needle or
Cell taking gun carries out tissue sample extraction along puncture casing is inserted into the patient.
Compared with prior art, this utility model passes through the real-time home position of position sensor, angle-data, in conjunction with operation
Navigation system, is possible not only to reduce CT equipment and uses the time, thus increase operation rate, and reduce radiation injury, and can be with
Few enter the precision that pin number of times reaches high, safe, practical, economical.
Accompanying drawing explanation
By being more particularly described of the preferred embodiment of the present utility model shown in accompanying drawing, of the present utility model on address
Other purpose, feature and advantage will become apparent from.The part that reference instruction identical in whole accompanying drawings is identical.Do not carve
