Abstract:
1. A syringe for injecting a surgical thread, comprising: a needle part adapted to penetrate the skin while accommodating a surgical thread and comprising a needle having an injection hole to accommodate the surgical thread therein and a coupling means having a tapered coupling space formed therein to allow the needle to be coupled to one side thereof and a stepped latching portion protruding from the wide tapered end of the coupling space; a connection part connected to the needle part by taper coupling and fixedly fastened to the needle part by turning operation of the needle part; and an injection part coupled to the connection part at the front end of a housing having a hole formed therein to allow a push needle coupled to the front end of a rod coupled to and linearly reciprocating along the hole and cooperating with the rod to push the surgical thread accommodated in the needle part and to inject the surgical thread into a skin tissue in a syringe operation manner, wherein the connection part comprises: an introduction portion having an inclined outer circumference adapted to be introduced into the coupling space of the coupling means to allow for primary taper coupling to the needle part and a connection hole formed at the center thereof to be in communication with the injection hole of the needle; a flange spaced outwardly from the introduction portion to create a fixing space therebetween and having a female-threaded portion formed on the inner circumference of the fixing space so as to be fixedly fastened to the needle part by turning operation after the stepped latching portion is engaged with the female-threaded portion; and a fastening portion having a fastening space formed at the rear of the flange and fixedly fastened to the front end of the injection part in the fastening space, whereby, with temporal taper coupling of the introduction portion in the coupling space of the coupling means, coupling of the connection part and the coupling means is completed in a quick and precise manner, and the injection hole and the connection hole precisely communicate with each other so that the push needle can precisely enter the injection hole; and the stepped latching portion of the needle part is fastened to the female-threaded portion formed at the front end of the connection part, thereby maintaining hermetic fixing of the needle part to the injection part.
