Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is the bone cement syringe.
Background technology
For compression fracture of vertabral body, take operative treatment, need be at Intrapyramidal gap injection bone cement.The bone cement syringe is made up of syringe and puncture needle, syringe comprises plastics lever and rustless steel body, puncture needle comprises plastic handle and rustless steel needle body, the puncture needle swing handle is in the breach of syringe lever top and both are threaded, and the inclined-plane of the inclined-plane of syringe barrel bottom and puncture needle needle body bottom is in the same plane, could form tip.During use, after puncture needle and syringe are gone into perverse putting in place, puncture needle is separated with syringe, bone cement injects in the space of vertebral body by syringe.Above-mentioned bone cement syringe construction is complicated, so cost is higher, and above-mentioned bone cement syringe is disposable apparatus, and for patients, medical expense is also just along with raising.
Make novel content in fact
This utility model purpose is to propose a kind of bone cement syringe simple in structure.
The utlity model has syringe and puncture needle, for achieving the above object, syringe is pegged graft by swing handle and body and is formed, and swing handle is "T"-shaped; Puncture needle is pegged graft by lever and needle body and is formed, and the lever bottom is provided with the "T"-shaped groove that matches with the swing handle of syringe; Both overlap fashionable, and the needle body of puncture needle places the swing handle of the body of syringe and syringe to place the "T"-shaped groove of the lever of puncture needle.
Above-mentioned syringe barrel top is cylindric protruding cover, and the cylindric protruding cover of body inserts in the swing handle; Above-mentioned puncture needle needle body top is a cylindrical boss, and the cylindrical boss of needle body inserts in the lever.
For the swing handle that guarantees syringe firmly is connected with body, be provided with alignment pin between the cylindric protruding cover of swing handle and body; For guaranteeing that the puncture needle lever firmly is connected with needle body, is provided with alignment pin between the cylindrical boss of lever and needle body.
Above-mentioned puncture needle lever is wooden.
Above-mentioned syringe swing handle is wooden.
Can be provided with the inclined-plane around the mouth of pipe of syringe barrel bottom, puncture needle needle body bottom is provided with the inclined-plane, and when syringe and puncture needle overlap fashionablely, the chamfered portion on the puncture needle needle body stretches out in syringe barrel 1～5mm.
Also can be equipped with the inclined-plane in the bottom of puncture needle needle body and the bottom of syringe barrel, when both overlap fashionablely, inclined-plane and the inclined-plane on the syringe barrel on the puncture needle needle body are in the same plane.
This utility model takes the "T"-shaped swing handle of syringe to be in the "T"-shaped groove of puncture needle lever, so have advantage simple in structure, easy to use; Especially the chamfered portion that adopts the puncture needle needle body is stretched out in the structure of syringe barrel, puncture needle and syringe cover are fashionable, rotate directionless requirement, so more convenient in the use; This utility model is taked wooden handle, can carry out high-temperature sterilization to non-damageable puncture needle, reuse, and be the little swing handle easy to process of volume once using what be provided with on the syringe just can't clean, can reduce the cost of syringe like this, for patients, do not need to pay the expense of a whole set of bone cement syringe, medical expense is also just along with reduction.
