Abstract

The present invention provides a puncture needle device, comprising a light source assembly, an optic fiber assembly, an ejection assembly, and a puncture needle assembly, wherein the light source assembly comprises a light source sleeve configured with a light source, the optic fiber assembly comprises an optic fiber sleeve configured with an optic fiber, the ejection assembly comprises an ejection sleeve configured with an ejection spring, and the puncture needle assembly comprises a puncture needle with a catheter.

Claims

1. A puncture needle device comprising a light source assembly, an optic fiber assembly, an ejection assembly, and a puncture needle assembly, wherein the light source assembly comprises a light source sleeve configured with a light source, the optic fiber assembly comprises an optic fiber sleeve configured with an optic fiber, the ejection assembly comprises an ejection sleeve configured with an ejection spring, and the puncture needle assembly comprises a puncture needle with a catheter.

8. A method of using the puncture needle device of claim 1, comprising the following steps:

(A) determining an intending puncture area on an organ with a lumen or cavity;

(B) activating the light source of the light source assembly;

(C) observing at least one projection of the light on the organ and adjusting the orientation of the puncture needle device to aiming at a proper puncture site according to the shape of the at least one projection;

(D) launching the ejection sleeve the ejection assembly to allow the puncture needle assembly to puncture into the lumen or cavity of the organ; and

(E) leaving the catheter and removing the puncture needle and the optic fiber along with the rest of the puncture needle device.

2. A puncture needle device comprising:

a light source assembly comprising a switch unit, a light source sleeve, and an adaptor unit;

an optic fiber assembly comprising an optic fiber sleeve, a stopper positioned within the optic fiber sleeve, and an optic fiber positioned axially within the optic fiber sleeve;

an ejection assembly comprising an ejection sleeve, an ejection spring, and an ejection button module, wherein a rear end of the ejection sleeve is configured with a puncture needle adaptor unit, the ejection sleeve is slidable within the optic fiber sleeve, and the ejection spring is positioned within the ejection sleeve; and

a puncture needle assembly comprising an over-the-needle catheter, a puncture needle, and a connector for coupling to the puncture needle adaptor unit of the ejection assembly.

3. The puncture needle device of claim 2, wherein the ejection button module comprises at least one ejection button, and at least one positioning hole configured at the surrounding of the ejection sleeve.

4. The puncture needle device of claim 3, wherein the ejection sleeve is configured with at least one positioning groove in the shape of “

L” and

have a longitudinal guiding section and a horizontal positioning section; and

the at least one ejection button passes through the at least one positioning groove and fixed to the at least one positioning hole.

5. The puncture needle device of claim 2, wherein a rear end of the switch unit is coupled to a front end of the light source sleeve, and the adaptor unit is coupled to a rear end of the light source sleeve.

6. The puncture needle device of claim 2, wherein a front end of the switch unit is configured with a switch;

a battery is positioned within the light source sleeve;

the adaptor unit is configured with a LED module and a battery contact spring.

7. The puncture needle device of claim 2, wherein the stopper is positioned within the optic fiber sleeve at a front end of the optic fiber sleeve;

and the optic fiber is positioned axially within the optic fiber sleeve, with a front end thereof fixed to the stopper and a rear end thereof extending into and protruding slightly out of the puncture needle assembly.
