Abstract
The utility model discloses a tumor biopsies sampling needle, and relates to the technical field of medical equipment. The tumor biopsies sampling needle comprises a puncturing tube. A cutting knife is arranged in the puncturing tube. The front end of the puncturing tube is provided with a sampling hole, and the rear end of the puncturing tube is provided with a handle. The front end of the cutting knife is of a semi-circular shape, and the rear end of the cutting knife is provided with the handhold. Scale marks are arranged on the puncturing tube, and the front end of the puncturing tube is provided with an annular interlayer containing the air. When the tumor biopsies sampling needle is used, the sampling needle works under the guidance of ultrasound, due to the fact that the ultrasound has strong reflectivity to the air, the boundary between the annular interlayer containing the air at the front end of the puncturing tube of the tumor biopsies sampling needle and the tumor and surrounding tissues on an ultrasonic machine screen is clear, so that a physician of the oncology department can be helped to judge the needle inserting condition, and the scale on the puncturing tube can be read conveniently; The air annular interlayer is processed and produced conveniently, only a section of stainless steel round tube with the diameter slightly larger than or slightly smaller than that of the puncturing tube of the sampling needle needs to be cut to be welded to the front end portion of the puncturing tube of the sampling needle, and thus the tumor biopsies sampling needle is low in cost.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of tissue sampler, relates in particular to a kind of tumor biopsy sampling probe.
Background technology
Early discovery, correctly diagnosis and in time treatment have important impact to the prognosis of tumor.Along with the improving constantly of detection methods and method, the accuracy rate of diagnosing tumor is improved gradually in recent years, but still have tumor greatly not possess typical Imaging Features, therefore simple image technology inspection exists the problem of difficult diagnosis.That diagnosis accurately needs is clinical, image and pathology three combinations, and wherein, biopsy diagnosis plays pivotal role to the selection of therapeutic scheme.Biopsy comprises puncture cutting and two kinds of forms of open biopsy, open biopsy is the method that adopts surgical incision, operate and not only extremely bother, waste time and energy, and operative incision is larger, indolence, the tumor tissues taking out is directly exposed in air, is easily polluted, and affects the accuracy of assay; Therefore the puncture needles that use obtain tumor tissues specimen more clinically, but because its needle point is beveled edge, can not effectively cut tissue, so, drawing materials in process of this type of specimen, be difficult to obtain effective tissue specimen.There is people to improve existing technology for this reason, as disclosed by utility model patent Dong Chonglin, Sun Mingxiao design, that the patent No. is 201020677852.1, name is called tissue specimen sampling probe on November 27th, 2013 in State Intellectual Property Office, it comprises puncture tube, in puncture tube, be provided with cutter, puncture tube front end is provided with thief hole, rear end is provided with handle, and cutter front end is semicircle, and rear end is handle.During use, the thief hole of puncture tube front end is punctured in tumor, tumor tissues will be trapped in thief hole, at this moment rotates the handle of cutter, and semicircular cutter will cut down the tumor tissues being trapped in thief hole, simple in structure, easy to operate, otch is little.But there is no scale on the puncture tube of this common sampling probe, depth of needle is difficult for holding, even locate by means of B ultrasonic, because puncture tube is not ultrasonic very clear with tumor and surrounding tissue boundary down, especially for often not seeing the doctor of ultrasonoscopy, also need sonographer to hold a consultation, to help oncologist to judge inserting needle situation.
Summary of the invention
The purpose of this utility model is to provide a kind of tumor biopsy sampling probe, to solve because common sampling probe is ultrasonic very not clear with tumor and surrounding tissue boundary down, allows oncologist feel unhandy problem.
The technical scheme that this utility model adopted is for achieving the above object:
A tumor biopsy sampling probe, comprises puncture tube, is provided with cutter in puncture tube, and puncture tube front end is provided with thief hole, and rear end is provided with handle, and cutter front end is semicircle, and rear end is handle, it is characterized in that: on described puncture tube, be provided with scale mark.
Front end at described puncture tube is provided with the annular gap that contains air.
During use, sampling probe of the present utility model carries out under ultrasonic guidance, due to ultrasonic, air is had to strong reflexive, the annular gap that can make the front end of this utility model sampling probe puncture tube contain air is clear with tumor and surrounding tissue boundary on ultrasonic machine fluorescent screen, can help oncologist to judge inserting needle situation, and can read easily the scale arranging on puncture tube, the processing and fabricating of air annular gap is also more convenient, only need one section of diameter stainless pipe slightly larger or slightly little than the diameter of sampling probe puncture tube of intercepting to be welded in the front end position of sampling probe puncture tube, cost is lower.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of tumor biopsy sampling probe of this utility model.
In Fig. 1: 1-puncture tube, 2-cutter, 3-thief hole, 4-handle, 5-handle, 6-scale mark, 7-annular gap.
The specific embodiment
Referring to accompanying drawing, a kind of tumor biopsy sampling probe adopts stainless steel material to make, comprise puncture tube 1, in puncture tube 1, be provided with cutter 2, puncture tube 1 front end is provided with thief hole 3, and rear end is provided with handle 4, cutter 2 front ends are semicircle, rear end is handle 5, is provided with scale mark 6 on described puncture tube 1, and the front end of puncture tube 1 is provided with the annular gap 7 that contains air.
