Description
Technical field
What the present invention relates to is a kind of device of technical field of medical instruments, specifically a kind of CT guided lung puncture positioning instrument.
Background technology
Transthoracic Biopsy is a kind of method of diagnosis pulmonary lesion commonly used, needs position and the size of utilizing medical imaging diagnosis to go out focus before the art, and cooks up the target spot of puncture, the entry point of puncture and paracentesis depth.Then the Transthoracic Biopsy that begins to carry out under the medical image guiding after the local skin sterilization to entry point is performed the operation, and medical image is applied to Transthoracic Biopsy, improves puncture success rate, has reduced pneumothorax, hemorrhage and some other complication.After puncture needle arrives predetermined pathological tissues, gather biological tissue, extract puncture needle, take out biological tissue and carry out biopsy.
Along with the CT image documentation equipment is fast-developing, the CT Guided Percutaneous Biopsies for Lung Lesions is one of inspection method of pathological changes in the Diagnosis of pulmonary.But present CT Guided Percutaneous Biopsies for Lung Lesions adopts hand operation.Because it is very complicated to carry out the aspiration biopsy location in three dimensions, difficulty is larger, and present CT guided percutaneous transthoracic lung biopsy still is confined to carry out in the two dimensional surface, and puncture path is selected to be restricted.When carrying out aspiration biopsy, the puncture needle position does not have quantitative data to determine, operator's empirical observation CT image is adjusted the direction of puncture needle, needs repeatedly to regulate just to reach correct puncture direction.When puncturing, every puncture certain depth needs the CT scan checking, and the patient is according to the angle of micro-judgment difference; And puncture needle do not have fixture to fix, and carrying out the CT scan checking to the alternation procedure that punctures, and attitude changes puncture needle owing to losing that staff is controlled with patient's respiratory movement.Therefore, need repeatedly CT scan, repeatedly explore point of puncture, puncture angle, paracentesis depth, operating time is long, and repeated puncture has increased the weight of the damage ratio of injury of pleura and needle track and focus peripheral vessels, and repeatedly CT scan has increased patient's radiation damage.Therefore, improving puncture success rate is the key that reduces complication.
Find through the retrieval to prior art, Chinese patent literature CN200977172Y, open day 2007-11-21, put down in writing CT guided puncture locating rack, this technology comprises stand, U-shaped fixed arm, orientation lever and fixing head, the puncture positioning action can only carry out in two dimensional surface, and the puncture direction is very limited.
Further retrieval is found, Chinese patent literature CN200977171Y, open day 2007-11-21, put down in writing a kind of CT localised puncture angle locater, this technology comprises concentric discs, graduation mark and puncture needle etc., the puncture positioning action also can only carry out in two dimensional surface, and the puncture direction is very limited.
In sum, lung puncture under the CT guiding is a kind of method that is widely used in the pulmonary lesion diagnosis, change traditional puncture mode, for improving the puncture one-time success rate, the incidence rate and the CT scan number of times that reduce complication have vital effect, the safety of CT guided percutaneous transthoracic lung biopsy is further improved, be conducive to the further popularization of CT guided percutaneous transthoracic lung biopsy.
