Abstract
The utility model discloses a kind of testis tissue puncture instrument for extracting, comprise needle tubing, be placed in the pitch brace of needle tubing inside and be placed in the syringe needle of needle tubing front end, described needle tubing afterbody is provided with edge perpendicular to the outward extending support end in needle tubing outer wall direction, on described support end with needle tubing axis for axis of symmetry is arranged with pole, described pole end is provided with palm support portion, described needle tip sealing, described syringe needle side is provided with knife edge face breach.This utility model is convenient to one-handed performance in operation, and prevent the tissue sucking syringe needle from dropping, surgical wound is little.
Description
Technical field
This utility model relates to a kind of reproduction medical auxiliary apparatus, is specifically related to a kind of testis tissue puncture instrument for extracting.
Background technology
Part male sterility crowd because cannot search out sperm from its seminal fluid, need to adopt testicular biopsy sperm aspiration (Testicular sperm aspiration, TESA) Extraction parts convoluted seminiferous tubule tissue from testis tissue, and tissue is analyzed, search and whether there is sperm.
In TESA art, a large amount of ordinary syringe that uses carries out clinical manipulation.Dress syringe needle on the injector enters testis through skin penetrating, keeps negative pressure multi-direction puncture in testis, cutting convoluted seminiferous tubule to obtain specimen; Tweezers are then used to remove one piece of convoluted tubule of testis tissue be pumped to outside skin of scrotum.
In existing TESA art, must syringe negative-pressure be kept, and need to cut off tissue simultaneously.Main Problems existing is:
(1) ordinary syringe maintains negative pressure and need to push pin downwards cylinder with hands, is not easy to doctor's one-handed performance, and is easy to the tissue of suction syringe needle is dropped;
(2), when cut-out is organized, need repeated localised puncture, easily cause wound excessive.
For solving the problem, need the syringe used in existing TESA art be improved.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of testis tissue puncture instrument for extracting, is convenient to one-handed performance in operation, and prevent the tissue sucking syringe needle from dropping, surgical wound is little.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of testis tissue puncture instrument for extracting, comprise needle tubing, be placed in the pitch brace of needle tubing inside and be placed in the syringe needle of needle tubing front end, described needle tubing afterbody is provided with edge perpendicular to the outward extending support end in needle tubing outer wall direction, on described support end with needle tubing axis for axis of symmetry is arranged with pole, described pole end is provided with palm support portion, and described needle tip sealing, described syringe needle side is provided with knife edge face breach.
The long 2mm of described knife edge face breach, wide 1mm.
The operational approach of this utility model in operation is: be placed in by syringe needle on testis tissue, left hand two refers to be placed on pitch brace position respectively, palm when held palm support portion, palm presses down simultaneously, finger pull-up, complete negative pressure action, testis tissue will be gathered in knife edge face breach through negative pressure, now, right hand Medical forceps will be organized in knife edge face breach and cut off.
Because technique scheme is used, this utility model compared with prior art has following advantages:
This utility model arranges palm support portion at needle tubing end, coordinate finger lift pitch brace to realize one hand by palm pressing palm support portion and complete negative pressure action, syringe needle interruption is sealed in syringe needle side simultaneously and knife edge face breach is set, the tissue that knife edge face cuts off directly falls in syringe needle, effectively prevents tissue from dropping.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model in embodiment one.
Wherein: 1, needle tubing; 2, pitch brace; 3, syringe needle; 4, support end; 5, pole; 6, palm support portion; 7, knife edge face breach.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described:
Embodiment one: shown in Figure 1, a kind of testis tissue puncture instrument for extracting, comprise needle tubing 1, be placed in the pitch brace 2 of needle tubing inside and be placed in the syringe needle 3 of needle tubing front end, described needle tubing afterbody is provided with edge perpendicular to the outward extending support end 4 in needle tubing outer wall direction, on described support end with needle tubing axis for axis of symmetry is arranged with pole 5, described pole end is provided with palm support portion 6, and described needle tip sealing, described syringe needle side is provided with knife edge face breach 7.
In the present embodiment, the long 2mm of described knife edge face breach, wide 1mm.
Claims (2)
