Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of special-purpose sternal puncture needle.
Background technology
Clinically, the diagnosis of some disease need be done bone marrow cytomorphologic examination, when doing bone marrow cytomorphologic examination, must carry out the bone marrow aspiration operation, extract bone marrow, before there are tibia, an ilium in the position of bone marrow aspiration operation, posterior superior iliac spine, ridge is prominent and breastbone etc., and is the abundantest with the bone marrow of breastbone, draw materials preferably, and be the site of puncture of the best.Usually the marrow puncture needle that is applied to clinically is conventional, traditional marrow puncture needle, its deficiency: the one since when puncture many before tibia, ilium, the posterior superior iliac spine puncture, in the medullary cavity at these positions relatively little or when puncture, be difficult for the location, easily causes puncture failure; The 2nd, the puncture needle diameter is generally No. 12 or No. 16, during puncture damage big, be easy to cause the danger of blood vessel behind the breastbone, heart and injury.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and a kind of rational in infrastructure, easy to operate, accurate positioning, special-purpose sternal puncture needle that penetration damage is little are provided.
The technical scheme that its technical problem that solves this utility model adopts is:
A kind of special-purpose sternal puncture needle, be provided with syringe needle, it is characterized in that being provided with sebific duct, push away handle and syringe jacket mouth, syringe jacket mouth flare, the syringe needle tail end is provided with and pushes away handle, push away the handle lower end and be provided with location wing, location when being beneficial to puncture, sebific duct one end is connected with syringe needle through pushing away handle, and the other end is connected with the syringe jacket mouth is small-bore, sebific duct is provided with control valve, is sucked into needle tubing with the bone marrow that prevents to extract.
Syringe needle in this utility model adopts No. 7 syringe needles, so that the damage during puncture is little.
This utility model is owing to adopt said structure, has advantages such as rational in infrastructure, easy to operate, accurate positioning, penetration damage be little.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Reference numeral: syringe needle 1, sebific duct 2, push away handle 3, syringe jacket mouth 4, control valve 5, location wing 6.
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is further specified:
As shown in drawings, a kind of special-purpose sternal puncture needle is provided with syringe needle 1, it is characterized in that being provided with sebific duct 2, pushes away handle 3 and syringe jacket mouth 4, syringe jacket mouth 4 flares, syringe needle 1 tail end is provided with and pushes away handle 3, pushes away handle 3 lower ends and is provided with location wing 6, the location when being beneficial to puncture, sebific duct 2 one ends are connected with syringe needle 1 through pushing away handle 3, the other end and 4 small-bore being connected of syringe jacket mouth, sebific duct 2 is provided with control valve 5, is sucked into needle tubing with the bone marrow that prevents to extract.
Syringe needle in this utility model adopts No. 7 syringe needles, so that the damage during puncture is little.
This utility model in use, the hand-held handle 3 that pushes away, No. 7 syringe needles 1 are pierced in the breastbone, syringe needle is behind the location wing location, and the reuse medical adhesive tape is fixed, and aims at syringe jacket mouth 4 with 10 milliliters of syringes and extracts bone marrow of sternum, bone marrow is flowed in the sebific duct 2, when extraction bone marrow is extremely a certain amount of, promptly sebific duct 2 is stopped with the control valve on the sebific duct 25, send to chemical examination then and get final product.
This utility model is owing to adopt said structure, has advantages such as rational in infrastructure, easy to operate, accurate positioning, penetration damage be little.
