A kind of clinical medicine biopsy sampling collection deviceTechnical field
The present invention relates to medicine sampling technique field, in particular to a kind of clinical medicine samples collection device with biopsy.
Background technique
Referred to as " biopsy ", also known as surgical pathology inspection referred to as " is examined " outside for biopsy (biopsy)；Refer to and sees patientsDisconnected, treatment needs cut from patient's body, clamp to take or puncture etc. and take out pathological tissues, carry out the technology of pathological examination.ItIt is most important part in Diagnosis pathology, specific histopathological diagnosis, quilt can be made to most inspection casesAs clinical final diagnosis.
But existing sampler, negative-pressure ward sample is mostly carried out by the structure of syringe styled, due to samplingNeedle tubing is comparatively fine, and the sample of suction is less, and is easy blocking, and hollow column strength is low, is easy at work curvedQu Zaocheng sampling is inaccurate, and the sample after collection is also not easy to take out.
Summary of the invention
For above-mentioned deficiency in the prior art, the present invention provides a kind of biopsies of clinical medicine to sample collection device,It is using simple, sampling is convenient.
In order to achieve the above object of the invention, the technical solution adopted by the present invention are as follows:
A kind of clinical medicine biopsy sampling collection device, including sampling portion and operation handle, the sampling portion include wearingPricker and the needle tubing being set on the outside of puncture needle, the top of the puncture needle are equipped with the small tip of feeding resistance, the puncture needleSurface be equipped with sampling groove, the sampling groove is arranged in the bottom at tip, is equipped on the sampling groove by subapical sideSampling cutter, the puncture needle slide are connected to inside needle tubing, and the operation handle is equipped with the connector of protection needle tubing, described to takeThe one end in sample portion extends to and is connected with Mobile base in operation handle, and the needle tubing is detachably connected with Mobile base, the Mobile baseIt is interior to be equipped with cavity, it is equipped with link block in the cavity, the puncture needle is threadedly coupled with link block, the other end of the link blockEquipped with compression set, the operation handle is equipped with the elongated hole for being parallel to puncture needle, and the both ends of the elongated hole are equipped with severalFor the short-bore of limit, the elongated hole is equipped with the mobile operating block of control Mobile base, and the operating block is equipped with control and wearsThe rotation key of pricker work.
Further, the tip is beak shape structure.
Further, the compression set is compressed spring, and one end of the compressed spring is connect with link block, the compressionThe bottom of the other end connection Mobile base of spring.
Further, the bottom end of the rotation key is connected with rotating bar, and the rotating bar is equipped with for compressing link blockCompact heap.
Further, the operation handle is equipped with anti-skid bulge.
Further, the puncture needle and needle tubing use stainless steel and nichrome high-strength material.
Further, the operation handle uses polypropylene material.
The invention has the benefit that the setting of needle tubing and puncture needle, guarantees that puncture needle can accurately reach sample point, puncturesThe point resistance of the beak shape of needle is smaller, and convenient deeply rotation key rotates the quick stretching of control puncture needle and withdraws, and samplesKnife is retracted into sample cutting sampling to sampling groove inside needle tubing, guarantees that sample is not poured down or forth out during needle tubing detaches,Lead to the diffusion of virocyte, safer, the setting of sampling groove is more convenient to take out samples taken.

Specific embodiment
Further illustrate a specific embodiment of the invention with reference to the accompanying drawing.Wherein identical components are with identicalAppended drawing reference indicates.
It should be noted that word "front", "rear" used in the following description, "left", "right", "up" and "down" refer toDirection in attached drawing, word "inner" and "outside" refer respectively to the direction towards or away from geometric center of specific component.
In order that the present invention can be more clearly and readily understood, following will be combined with the drawings in the embodiments of the present invention,Technical scheme in the embodiment of the invention is clearly and completely described.
As shown in the picture, a kind of clinical medicine biopsy samples collection device, including sampling portion 1 and operation handle 2, describedSampling portion 1 includes puncture needle 3 and the needle tubing 4 for being set in 3 outside of puncture needle, and it is small that the top of the puncture needle 3 is equipped with feeding resistanceTip 4.1, the surface of the puncture needle 3 is equipped with sampling groove 4.2, and the bottom at tip 4.1 is arranged in the sampling groove 4.2,Side on the sampling groove 4.2 close to tip 4.1 is equipped with sampling cutter 4.3, and the puncture needle 3 is slidably connected inside needle tubing 4,The operation handle 2 is equipped with the connector 5 of protection needle tubing 4, and the one end in the sampling portion 1 extends to connection in operation handle 2There is Mobile base 6, the needle tubing 4 is detachably connected with Mobile base 6, and cavity 7 is equipped in the Mobile base 6, is equipped in the cavity 7Link block 8, the puncture needle 3 are threadedly coupled with link block 8, and the other end of the link block 8 is equipped with compression set 9, the behaviourMake handle 2 and be equipped with the elongated hole 10 for being parallel to puncture needle 3, the both ends of the elongated hole 10 are equipped with several short-bore for limit11, the elongated hole 10 is equipped with the mobile operating block 12 of control Mobile base 6, and the operating block 12 is equipped with control puncture needle 3The rotation key 13 of work.
The tip 4.1 is beak shape structure.
The compression set 9 is compressed spring, and one end of the compressed spring is connect with link block 8, the compressed springThe other end connection Mobile base 6 bottom.
The bottom end of the rotation key 13 is connected with rotating bar 13.1, and the rotating bar 13.1 is equipped with for compressing connectionThe compact heap 13.2 of block 8.
The operation handle 2 is equipped with anti-skid bulge.
The puncture needle 3 and needle tubing 4 use stainless steel and nichrome high-strength material.
The operation handle 2 uses polypropylene material.
In the device use process, sampling portion is linked together with operation handle, controls operating block in operation handleElongated hole forward slip, the bottom end of operating block connect with Mobile base, drive Mobile base in operation handle move forward inside, fromAnd sampling portion is driven to arrive forward sample point, operating block is fixed in the limit short-bore of elongated hole one end, then control rotationKey rotates 90 ° so that the compact heap for compressing link block is detached from from link block, entrance so that compression set by compressing positionBecome to extend position, so that puncture needle is stretched out out of needle tubing, the tip of puncture needle drives puncture needle forward, then to press rotation rapidlyKey resets, and puncture needle is withdrawn, and sampling cutter is retracted into sample cutting sampling to sampling groove inside needle tubing, guarantees sample in needlePipe is not poured down or forth out during detaching, and leads to the diffusion of virocyte, safer, then controls sampling portion and takes out from sample point?.
The above description is only a preferred embodiment of the patent of the present invention, is not intended to limit the invention patent, all at thisMade any modifications, equivalent replacements, and improvements etc., should be included in the invention patent within the spirit and principle of patent of inventionProtection scope within.
