Description
Technical field
This utility model relates to technical field of medical instruments, specifically breast tissues sampling puncture needle.
Background technology
The diagnostic method of breast carcinoma is a lot, comprise have a medical check-up, mammary X-ray photography, B ultrasonic, breast duct endoscope etc., but final making a definite diagnosis still will rely on pathological diagnosis.Biopsy (abbreviation biopsy) obtains the most frequently used means of preoperative pathological diagnosis, and it comprises puncture needle biopsy and open surgical biopsy two kinds of methods.
Puncture needle biopsy is compared with open surgical biopsy, and the destruction of puncture needle biopsy normal tissue is few, and without cicatrix, patient only needs local anesthesia, and expense also relative moderate.The most important thing is that aspiration biopsy can make the patient of a part of benign breast lesions eliminate unnecessary operation.Health check-up is found to the patient of lump in breast, also can adopt the method that open surgical biopsy and operative treatment carry out simultaneously.But this method is unfavorable for that operation consent formulates detailed therapeutic scheme, and extends the time of operation.If preoperative puncture needle biopsy malignant change, not being only further treatment provided according to (comprising operation and preoperative adjuvant chemotherapy), and was conducive to the mode that doctor and patient discuss operative treatment jointly, such as, whether take the operation etc. of Remainded mamma.
The breast tissues sampling puncture needle used in existing puncture needle biopsy, as Chinese Patent Application No. " a kind of for breast carcinoma pathological biopsy puncture needle " (Authorization Notice No. CN203059869U) disclosed in the patent documentation of ZL201320092067.3, it arranges sample tap in side, puncture tube front end, in puncture tube, sliding bar is set, sliding bar end arranges semicircle cutter, after puncture tube is inserted into pathological tissues, after pathological tissues is absorbed in thief hole, parts of lesions tissue cut off by rotational slide bar.There is thief hole and be positioned at puncture tube side in this structure, causes insertion depth comparatively deeply pathological tissues just can be made to be trapped in thief hole, and some patients breast lesion lump tumor in the form of sheets, its injured depth is not enough to the structure supporting this thief hole.After rotation sliding bar cuts off the following defect pathological tissues of part, be easy to come off after taking-up puncture tube, be difficult to obtain pathological tissues smoothly although cut off, its structure does not preserve the space of sample.
For solving the problems of the technologies described above, to this has been corresponding improvement, if China Patent No. is " breast tissues sampling puncture needle " (Authorization Notice No. CN203763129U) disclosed in the patent documentation of ZL201420140370.0, it arranges the swingle (in document, name is called: sliding bar) of band helical-blade in puncture needle tubing, one end of swingle is provided with swivel head, the other end is fixedly connected with rotating handle, and swivel head is fixedly connected with blade; Rotating handle inner hollow, is plugged and connected with tweezer in rotating handle, and the two ends of rotating handle are fastened and connected sealing cap.
But still there is following defect in it: the corresponding blade in front end of its helical-blade, the rear end of helical-blade is also open, in operation, there is maloperation, the number of turns that blade rotary-cut pathological tissues direction rotates is too much, the pathological tissues cut out is delivered to the rear end of helical-blade and is sent helical-blade position by existence, thus causes risk pathological tissues sheet cannot discharged from tip position; Although in the course of processing, helical-blade rear end is undertaken spacing by needle interior wall, and it exists certain fit clearance, also there is as above risk.
Summary of the invention
