Abstract
The utility model provides a diagnostic puncture biopsy probe-a spiral blade biopsy probe which is used for the medical care. The utility model is composed of a core probe, a sleeve pipe and a spiral probe. The utility model is characterized in that the front section of the spiral probe is provided with a single head square tooth spiral body, the depth of a spiral groove is the radius of the spiral probe, the top end of the spiral body is provided with a spiral edge, and the top end of the sleeve pipe is provided with an annular edge. The whole process of the biopsy probe for taking specimen is the cutting action, the damage for the specimen can be minimized, and the biopsy probe can ensure that the speciment can be taken out; the taken speciment can meet the diagnosis requirement of the cytology and the histology. The utility model is suitable for the puncture biopsy of the soft tissue and the non-hard bone tumor tissue.
Description
This utility model belongs to the soft tissue biopsy instrument that diagnostic puncture is used in a kind of medical treatment.
At present, the used biopsy needle of diagnostic puncture is gone up in medical treatment both at home and abroad, can be divided three classes substantially.The first kind is the aspiration biopsy fine needle, can obtain tissue fluid and do cytodiagnosis; Second class is that needle body or sleeve pipe have groove (or a plurality of little groove), by tissue elasticity or apply external force and make and organize in the embedded groove, cuts out specimen by squeezing; The 3rd class is that the biopsy needle top is hollow shape, produces side direction or longitudinal frictional force by tube wall side channel or spring-like pin section, makes tissue from the disconnected specimen of taking out through turning round, drawing.Back two classes can doublely be done cytology and histodiagnosis.The weak point of above-mentioned biopsy needle has: the first kind only can be done cytodiagnosis, and accuracy rate is not high.Second class has certain damage to the specimen structure, if tissue elasticity is poor, will can not get specimen in the time of can not applying external force again.The 3rd class has certain damage to the specimen structure, more toughly will can not get specimen if organize.Owing to these weak points, influenced the puncture reliability and the accuracy rate of diagnosis of these biopsy needles.
The purpose of this utility model provides a kind of easy to use, can take out specimen reliably organizing under the situation that is not subjected to squeeze, press, turn round, draw, and improves the biopsy needle of accuracy rate of diagnosis.
It is that the core pin of triangular pyramid is inserted the sleeve pipe that the top is the ring sword that task of the present utility model is achieved in that by a top, thrust skin and reach need biopsy position, reuse one leading portion is the spiral needle replacing core pin of helical sword for the spirillum top, spiral needle is along the hand of spiral, sleeve pipe rotary-cut in the other direction enters tissue, extracts spiral needle out and promptly take specimen out of in screw channel.
Describe structure of the present utility model and work process in detail below in conjunction with accompanying drawing.
Fig. 1. the core pin cooperates sketch map with sleeve pipe.
Fig. 2. the spiral needle sketch map.
Fig. 3. spiral needle helical sword sketch map.
This utility model comprises: core pin ［ 1 ］, sleeve pipe ［ 2 ］ and spiral needle ［ 3 ］ three parts.The point and the rib of core pin ［ 1 ］ top triangular pyramid ［ 4 ］ are all sharp.Sleeve pipe ［ 2 ］ top is sharp ring sword ［ 5 ］.Spiral needle ［ 3 ］ leading portion is single head, square spirochaeta dentium ［ 6 ］, and screw channel ［ 7 ］ degree of depth is the radius of spiral needle ［ 3 ］.Spirillum ［ 6 ］ top is an Archimedes spiral shape knife edge ［ 8 ］, and its fixed point is at spiral needle ［ 3 ］ axle central point.Spiral form knife edge and helical margin intersect formation blade tip ［ 9 ］.Core pin ［ 1 ］ and spiral needle ［ 3 ］ rear end all have cylindrical base ［ 10 ］, and sleeve pipe ［ 2 ］ rear end has hollow cylindrical pedestal ［ 11 ］.Core pin ［ 1 ］ all can be free to slide and contact in sleeve pipe ［ 2 ］ closely with spiral needle ［ 3 ］.Core pin ［ 1 ］ exposes triangular pyramid ［ 4 ］ when inserting sleeve pipe ［ 2 ］, expose spirillum ［ 6 ］ top one circle when spiral needle ［ 3 ］ is inserted sleeve pipe ［ 2 ］.
The external diameter of this biopsy needle, length and spirochetal pitch can be made into the series of different pieces of information, select for use according to the kind and the degree of depth of puncture tissue.
During aspiration biopsy, core pin ［ 1 ］ is inserted sleeve pipe ［ 2 ］, thrusts skin and reaches the need biopsy site.Extract core pin ［ 1 ］ out and change spiral needle ［ 3 ］.Screw in spiral needle ［ 3 ］ along the hand of spiral and screw in sleeve pipe ［ 2 ］ simultaneously in the other direction, blade tip this moment ［ 9 ］ thrusts, helical sword ［ 8 ］ cuts to make in the screw channel ［ 7 ］ and is full of tissue.Ring sword ［ 5 ］ is with screw channel ［ 7 ］ inner tissue and on every side the cut-out that is connected.When control spiral needle ［ 3 ］ is not advanced when still rotating, helical sword ［ 8 ］ will cut off being connected of screw channel ［ 7 ］ inner tissue and the place ahead.Because sleeve pipe ［ 2 ］ a circle is exposed on spiral needle ［ 3 ］ top,, organize in the groove of screw channel ［ 7 ］ top and being connected on every side to cut off so after spiral needle ［ 3 ］ quit work, sleeve pipe ［ 2 ］ should readvance one section.The overall process that cuts specimen like this is the minimum slip cutting action of damage.Extract sleeve pipe ［ 2 ］ together out and spiral needle ［ 3 ］ can be taken out specimen.Also can only extract spiral needle ［ 3 ］ out, enter sleeve pipe ［ 2 ］ once more after the taking-up specimen, cut specimen repeatedly.But the specimen smear is done cytodiagnosis, and histodiagnosis is done in fixing simultaneously, section.
The helical edges biopsy needle is easy to operate; Take the overall process of specimen to be the sharp sword cutting action, can avoid organizing and active force such as be squeezed, press, turn round, draw and will reduce to minimum the damage of specimen; Because knife edge cuts off specimen and being connected all of surrounding tissue, can guarantee to take out specimen; The specimen of getting can satisfy cytology and histodiagnosis requirement; Thereby increase the reliability and the accurate rate of diagnosis of aspiration biopsy.
