Abstract
The utility model relates to an integrated bone marrow puncturing needle for testing or transplanting bone marrow. The utility model is mainly composed of a needle head, a needle core and an injector, wherein, the needle core is directly arranged on an injector piston, and the needle core is caused to be connected with the piston and a push rod as a whole. The utility model has the advantages of simple structure, convenient industrialized production, lower cost, convenient operation, safety, etc. The utility model can be used as a disposable needle so that the problems of cross infection, etc. are avoided. The utility model overcomes the bad result produced by installing injectors halfway. The actions of drawing out the needle core and pumping marrow can be one time completed. The utility model is an ideal bone marrow puncturing needle.
Description
This utility model relates to a kind of surgical instruments of bone marrow transplantation and bone marrow check, particularly disposable integrated marrow puncture needle.
Traditional marrow puncture needle mainly is made up of syringe needle, needle holder and nook closing member, be used with syringe again, nook closing member is inserted in the syringe needle, can prevent obstruction pin holes such as bone bits during puncture, after syringe needle thrusts medullary cavity, nook closing member is transferred to, injection head with syringe is contained on the bellmouth of needle holder again, takes out marrow with syringe.Obviously there are shortcomings such as complicated operation in this split type marrow puncture needle, particularly in the process of transfering to nook closing member and mounting of syringe, increased the chance of courses of infection, and easily make the syringe needle shake even cause the syringe needle skew, increase misery to patient, can make syringe needle crooked and marrow is taken out in influence when serious, when doing the puncture of breastbone marrow, also cause unexpected injuries such as diaphragm injury or pneumothorax especially easily.
The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, design a kind of simple and reasonable, easy to operate, can avoid syringe needle shake and the anti-good integrated marrow puncture needle of performance that infects effectively.
Integrated marrow puncture needle of the present utility model comprises syringe needle, nook closing member and syringe, nook closing member is inserted in the syringe needle, bellmouth on the needle holder is enclosed within on the injection head of syringe front end, fixedlys connected with the piston of syringe in its nook closing member rear end, and the piston another side is fixedlyed connected with piston push rod.Wherein annexation is preferably: nook closing member rear end and push rod front end are made T shape shape respectively, and piston selects for use medical grade rubber to make, and has the shrinkage pool that can tighten nook closing member T shape rear end and push rod T shape front end on the piston both sides.
Accompanying drawing is a structural representation of the present utility model.
Referring to accompanying drawing, nook closing member 2 is contained in the syringe needle 1, bellmouth on the needle holder 4 is enclosed within on the injection head 5, nook closing member rear end 6 and push rod front end 10 are made T shape shape, piston 8 is made by medical grade rubber, have shrinkage pool 7 and 9 on both sides, respectively with nook closing member rear end 6 and push rod front end 10 chuckings, it is as a whole that nook closing member and piston and push rod are connected into, in nook closing member 2 can be packed syringe needle 1 forward into from the rear end of sleeve 12, when piston 8 was pulled to the end, the nook closing member front end was concordant with the syringe needle front end, in order to make nook closing member can activity again the better seal performance can be arranged in syringe needle, the nook closing member external diameter should be advisable than the thin 0.01-0.2mm of syringe needle internal diameter.In order to ensure depth of needle, can on needle holder, increase a depth adjuster 3.In use, only need hand-held syringe, syringe needle is lunged assigned position, can spur piston and take out marrow.
The utlity model has simple and reasonablely, be convenient to suitability for industrialized production, cost is lower, behaviour Make the advantages such as convenient and safe and reliable, can be used as the disposable pin of using, avoided cross-infection etc. to ask Topic has overcome because mounting of syringe midway produces adverse consequences, makes to transfer to nook closing member and take out the marrow energy Once finishing, is a kind of desirable marrow puncture needle.
