Description
Technical field
This utility model belongs to B ultrasonic technical field of medical instruments, relates to a kind of medical puncture needle.
Background technology
Biopsy needle is a kind of medical apparatus and instruments, is applicable to the multiple organs such as kidney, liver, lung, mammary gland, thyroid, prostate, pancreas, testis, uterus, ovary, body surface, can be used for the living tissue sampling of entity tumor and not clear tumor etc., draws cell.
Present routine autopsy pin mostly is needle puncture biopsy, though the method is easy and simple to handle, safer, shortcoming is that the amount of drawing materials is less, lack experience or draw materials position not at that time, not thrusting tumor district and obtain representational tumor tissue, and puncture after block organize comparatively difficulty, therefore, be badly in need of seeking a kind of quick, method that is accurate, that reduce sufferer misery of drawing materials in the process of punch biopsies.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides one and blocks tissue fast, and more medical puncture needle of drawing materials.
The purpose of this utility model realizes by following technical proposal: a kind of medical puncture needle, comprise needle stand, puncture needle and solid nook closing member, one end and the puncture needle afterbody of needle stand are connected, endoporus one is provided with along needle length direction in needle stand and puncture needle, it is characterized in that: also comprise the needle tubing that cross section is annular, there is in described needle tubing endoporus two, and needle tubing head penetrates endoporus one from needle stand afterbody, described nook closing member head penetrates endoporus two from needle tubing afterbody, described puncture needle comprises needle point and needle handle, described puncture needle needle handle has multiple notch one, described needle tubing offers multiple notch two, the endoporus one that described needle stand is corresponding is provided with the cannelure arranged along needle length direction, needle tubing outer wall is provided with ring block, and described ring block is located at, and cannelure is interior also can slide along needle length direction, spring is provided with between described cannelure one end and ring block, described nook closing member afterbody and needle tubing afterbody are respectively equipped with protruding one and protruding two, described projection one is resisted against on protruding two, and by squeeze towards puncture needle cephalad direction by or release projection two make the extruding of described ring block or trip spring, and make described notch one misplace with notch two or be communicated with.
By lancet puncture skin and after arriving object tissue, taken out by nook closing member, needle tubing connects syringe.Now protruding two is releasing orientation, therefore notch one is communicated with notch two, biopsy enters in the endoporus two of needle tubing by the negative pressure-pumping of syringe, as some notches one and notch two block time, by other notch one and notch two, biopsy is sucked, squeeze afterwards and make ring block extrusion spring by protruding two, and make notch one and notch two misplace to cut the biopsy sucked by notch one and notch two in endoporus two, release projection two also extracts puncture needle fast again afterwards, therefore a pin multidraw object is reached, and it is fast very convenient to cut off biopsy process, reduce the misery of patient.
In above-mentioned a kind of medical puncture needle, described notch one and notch two be circular and circumferential edge all in cutting edge shape.
Make Biopsy organizational process very quick by the notch one of cutting edge shape and notch two.
In above-mentioned a kind of medical puncture needle, described puncture needle head is provided with gear edge on endoporus one, and described nook closing member seamlessly can be fitted in gear along on inner face.
In above-mentioned a kind of medical puncture needle, when release projection two, described ring block is resisted against one end of cannelure, and now described nook closing member head is concordant with puncture needle head.
Therefore skin puncture process is more smooth.
Compared with prior art, this utility model tool has the following advantages:
By lancet puncture skin and after arriving object tissue, taken out by nook closing member, needle tubing connects syringe.Now protruding two is releasing orientation, therefore notch one is communicated with notch two, biopsy enters in the endoporus two of needle tubing by the negative pressure-pumping of syringe, as some notches one and notch two block time, by other notch one and notch two, biopsy is sucked, squeeze afterwards and make ring block extrusion spring by protruding two, and make notch one and notch two misplace to cut the biopsy sucked by notch one and notch two in endoporus two, release projection two also extracts puncture needle fast again afterwards, therefore a pin multidraw object is reached, and it is fast very convenient to cut off biopsy process, reduce the misery of patient.

Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but this utility model be not limited to these embodiments.
As Figure 1-3, a kind of medical puncture needle of this utility model, comprise needle stand 1, puncture needle 2 and solid nook closing member 3, one end and puncture needle 2 afterbody of needle stand 1 are connected, endoporus 1 is provided with along puncture needle 2 length direction in needle stand 1 and puncture needle 2, also comprise the needle tubing 4 that cross section is annular, there is in needle tubing 4 endoporus 2 41, and needle tubing 4 head penetrates endoporus 1 from needle stand 1 afterbody, nook closing member 3 head penetrates endoporus 2 41 from needle tubing 4 afterbody, puncture needle 2 comprises needle point 21 and needle handle 22, puncture needle 2 needle handle 22 has multiple notch 1, needle tubing 4 offers multiple notch 2 42, the endoporus 1 of needle stand 1 correspondence is provided with the cannelure 12 arranged along puncture needle 2 length direction, needle tubing 4 outer wall is provided with ring block 43, and ring block 43 is located at, and cannelure 12 is interior also can slide along puncture needle 2 length direction, spring 5 is provided with between cannelure 12 one end and ring block 43, nook closing member 3 afterbody and needle tubing 4 afterbody are respectively equipped with protruding 1 and protruding 2 44, protruding 1 are resisted against on protruding 2 44, and by towards puncture needle 2 cephalad direction squeeze by or release projection 2 44 ring block 43 is extruded or trip spring 5, and make notch 1 misplace with notch 2 42 or be communicated with.
Further, notch 1 and notch 2 42 be circular and circumferential edge all in cutting edge shape.Puncture needle 2 head is provided with gear along 24 on endoporus 1, and nook closing member 3 seamlessly can be fitted in gear along on 24 inner faces.When release projection 2 44, ring block 43 is resisted against one end of cannelure 12, and now nook closing member 3 head is concordant with puncture needle 2 head.
