Abstract
The utility model discloses a biopsy puncture sampling device, which mainly comprises a hollow probe [1] and a probe socket [2] to fix the probe [1]. The utility model is characterized in that a cutting edge [3] is arranged behind needle tip in the front of the probe [1], wherein a cutting slot [4] is arranged in front of the cutting edge [3], and a transverse cutting edge [5] is arranged between the cutting slot [4] and the cutting edge [3]. The utility model has the advantages that the probe is delivered to the disease site and rotated to cut thoroughly the disease tissue that enters into the cutting edge under both the vertical cutting of the cutting edge and the transverse cutting of the transverse cutting edge, and the tissue is kept in the cutting edge slot that prolongs into the probe, wherein the sampling is reliable and comparatively complete disease tissue can be obtained. The utility model is of a reasonable structure, easy and practical operation, and convenient and fast clinical usage.
Description
Technical field
This utility model belongs to a kind of medical apparatus and instruments, and definite saying is a kind of biopsy puncture sampler.
Background technology
Biopsy need be done for the in-vivo tissue that pathological changes is arranged by departments such as hospital just can determine it wherein is what pathological changes, and symptomatic treatment is done the section biopsy but generally all adopt puncture or minor operation opening to take out pathological tissues in the past then.Puncture generally is difficult to obtain pathological tissues, and that surgical openings also has a wound area is bigger, and the patient is the comparison misery, and the operation of darker pathological tissues just exceeded the scope of patient examination, needs special operation.Therefore there are not suitable apparatus and device to solve the problem of effective extraction of biopsy all the time.In order to address this problem, designer of the present utility model has done research in earnest, has proposed goal of the invention of the present utility model.
Summary of the invention
Goal of the invention of the present utility model puts forward for the deficiency that does not have suitable apparatus and device to extract biopsy that overcomes present existence.Be that goal of the invention of the present utility model provides a kind of biopsy puncture sampler.
Technical solution of the present utility model is to realize like this, this biopsy puncture sampler, mainly have the probe [1] of a hollow and the needle stand [2] of stationary probe [1], it is characterized in that having a cutting edge [3] in the front end needle point back of probe [1], the front of cutting edge [3] has a grooving [4], has chisel edge mouth [5] between grooving [4] and cutting edge [3].
Beneficial technical effects of the present utility model is: when probe arrives diseased region, make the pathological tissues enter in the cutting edge under the combined effect of the cross cutting of the straight-cut of cutting edge and chisel edge mouth, be cut off by rotating probe, and be trapped in the groove that cutting edge extends to probe interior, sampling is reliable, can obtain more complete pathological tissues form.Apparatus structure is reasonable, and is simple to operate, practical, clinical convenient to use.
Description of drawings
Accompanying drawing 1 is a structural profile schematic views of the present utility model, accompanying drawing 2 be the A of accompanying drawing 1 to partial view, accompanying drawing 3 is B-B profiles of accompanying drawing 1, accompanying drawing 4 is the A zoomed-in views in the accompanying drawing 2.Sequence number in the accompanying drawings is described as: 1, probe, 2, needle stand, 3, cutting edge, 4, grooving, 5, the chisel edge mouth.
The specific embodiment
Below in conjunction with the embodiment that provides in the accompanying drawing, structure of the present utility model and use are elaborated.With reference to accompanying drawing 1～4, this device mainly has the probe [1] of a hollow and the needle stand [2] of stationary probe [1], back at the front end needle point of probe [1] has a cutting edge [3], and the front of cutting edge [3] has a grooving [4], has chisel edge mouth [5] between grooving [4] and cutting edge [3].During puncture,, needle stand is connected a syringe, the part of the air sucking-off in the probe organizing of lesion of while also is inhaled into cutting edge [3] inside when probe arrives diseased region.Rotate an about week of probe then, cutting edge [3] is done straight-cut to pathological tissues, and chisel edge mouth [5] is made cross cutting to pathological tissues, enters into the interior pathological tissues of probe cutting edge just by complete scaling off.Probe is taken out, and with the syringe pushed home, pathological changes group tissue can be released probe from cutting edge [3], and the biopsy of cutting into slices is handled.
