Abstract
The utility model relates to medical equipment, in particularly to a testicular puncture needle comprising a needle tube fixedly connected to a needle holder, wherein a needle point in an inclined sharp-end shape is arranged at the bottom end of the needle tube; two or more than two tissue notches are formed on the needle tube in a way that the opening directions of the two adjacent tissue notches are not identical in the height direction of the needle tube; and the tissue notches with sharp edges are communicated with the inner hole of the needle tube. When in use, the testicular puncture needle of the utility model has the advantages of one-step completion, multi-point collection, flexible, quick and accurate use, micro-trauma operation, fewer complications, simple manufacturing process and economical and practical use and is easily accepted by patients, thus providing more valuable small equipment for the analysis and judgment of testicular spermatogenic function and the clinical application of assisted reproductive technology (ART) and serving as an economical and practical andrologic examination tool for various health-care units.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of testicular biopsy pin.
Background technology
Along with social industrialization degree is constantly accelerated, the transformation of people's life style, the disease of male sterility is more and more, and the testicular biopsy art is the main means of Clinics and Practices.Testis is in the past got smart art two kinds: the one, adopt the import puncture needle, and price is very expensive.A kind of is to cut to get smart art, but wound is big, the risk height, and patient's misery, and easily produce sequela such as infection.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, but when a kind of the use is provided wound little, alleviate the organ injury multi-point sampling, reduce the testicular biopsy pin of rate of missed diagnosis.
The technical scheme that provides according to this utility model, described testicular biopsy pin, be included in needle tubing fixedly connected on the needle stand, the bottom of needle tubing is a needle tip, needle tip is inclined-plane tip shape, offers two or more notches of organizing on needle tubing, and adjacent two opening directions of organizing notch are on the short transverse of needle tubing and shift to install, the described sharp edges of organizing notch, and organize notch to be communicated with the needle tubing endoporus.
It is described that to organize the degree of depth of notch be 1/3～1/2 of needle tubing diameter.
Adjacent two to organize the difference in height of notch be 2～4mm.
On needle tubing, be provided with the depth of needle sign.Difference in height between adjacent two depth of needle sign is 5mm.
This utility model has once in use to be finished, multi-point sampling, use flexibly, rapidly accurately, Wicresoft hinders, complication is few, processing technology is easy, economical and practical and patient is willing to advantages such as acceptance, for analyzing, judge that the spermatogenesis of testis and the clinical practice of auxiliary procreation technology (ART) provide a kind of more valuable little apparatus, can be used as a kind of economical and practical andrology indagation instrument of each medical institutions.

Fig. 1 is a front view of the present utility model.
Fig. 2 is a left view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: this testicular biopsy pin, be included in needle tubing fixedly connected on the needle stand 42, the bottom of needle tubing 2 is a needle tip 1, needle tip 1 is inclined-plane tip shape, on needle tubing 2, offer two or more notches 5 of organizing, and organize the opening direction of notch 5 on the short transverse of needle tubing 2, to shift to install for adjacent two, the described sharp edges of organizing notch 5, and organize notch 5 to be communicated with needle tubing 2 endoporus.
1/3～1/2 of the diameter that the described degree of depth of organizing notch 5 is a needle tubing 2.
Adjacent two to organize the difference in height of notch 5 be 2～4mm.
On needle tubing 2, be provided with depth of needle sign 3.Difference in height between adjacent two depth of needle sign 3 is 5mm.
This utility model in use, connect syringe on the needle stand 4, behind the needle point of the needle tubing 21 puncture testis, the negative pressure-pumping of testis tissue by syringe enters organizes notch 5, when organizing notch 5 to stop up, can organize notch 5 with the testis tissue sucking-off as some by other.The needle body of needle tubing 2 is carved with accurate depth of needle sign 3, adapts to requirement of different patients, can accurately locate the degree of depth of inserting needle, to have guaranteed the accuracy and the safety of operation.
