Description

LED lacrimal probe

Technical Field

The invention relates to a surgical instrument, in particular to a lacrimal probe with a light source, which is mainly used for auxiliary positioning and illumination in lacrimal surgery.

Background

In the existing lacrimal passage operation, in order to better position the lacrimal sac and the nasolacrimal duct so as to achieve the purpose of accurate operation, a method of fundus illumination optical fiber is generally used. However, the fundus illumination optical fiber is not designed for lacrimal duct operation, and the fundus illumination optical fiber equipment has large volume and high price, and cannot be popularized and applied. At present, the technologies of LED and gallium nitride and the like are gradually mature, and an LED light source can be small in size, high in brightness and low in cost.

Disclosure of Invention

In order to make the lacrimal probe with light source more commonly used in clinical operation. The invention aims to provide a lacrimal passage probe device which is reasonable in structural design, proper in size and high in brightness.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a LED lacrimal passage probe, probe head rocket cone shape design, the probe needle body outside is the alloy material, and inside is crystal leaded light material, and probe afterbody outside is metal or engineering material, and inside comprises lens, LED chip, battery module, heat dissipation layer, control chip, switch.

The invention adopts medical alloy material, is smooth and has no edges and corners, and is used for ethylene oxide sterilization.

Compared with the prior art, the invention has the following beneficial effects: 1. the probe head can be directly entered into the probe through the punctum when in use, and the use is convenient. 2. The light source has high brightness and the brightness can be quickly adjusted by the tail button. 3. The battery is replaceable, which is beneficial to prolonging the service life. 4. The needle body is provided with length unit scales, which is beneficial for the operator to judge the needle insertion depth. 5. The surface of the handle shell is provided with grains, so that the friction force is increased, and the handle is convenient for an operator to hold and apply force. 6. Can be controlled at lower cost.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described below by combining the specific drawings.

[ example 1 ]

Referring to fig. 1, the embodiment of an LED lacrimal probe includes a probe head 1, a probe body 2, a probe handle portion 3, a power switch 4, and a probe tail 5. The probe head part 1 is in a rocket cone shape, a round opening is a light source outlet, the probe body 2 is connected with the probe handle part 3, the power switch 4 is in a round structure and is positioned in the middle of the probe tail part 5, and the probe tail part 5 is connected with the probe handle part 3 to seal an internal structure.

[ example 2 ]

Referring to the embodiment of an LED lacrimal probe shown in fig. 1 and fig. 2, in this embodiment, the internal structure includes a crystalline light guide material 6, a lens device 7, an LED chip 8, a battery module 9, a heat dissipation material layer 10, a control chip 11, and a power switch button 12. After the power switch 4 is turned on, the control chip 11 enables the battery module 9 to drive the LED chip 8 to emit light through a circuit, and the light is condensed by the lens device 6 and then transmitted to the probe head 1 through the crystal light guide material 6.

[ example 3 ]

When the lacrimal probe is used, the lacrimal punctum is expanded, the grains of the probe shell of the handle part of the probe are held by fingers and enter the probe from the lacrimal punctum, the lacrimal sac is inserted into the lacrimal canaliculus through the lacrimal canaliculus and the lacrimal trunk, the power switch is switched on, the position and the size range of the lacrimal sac under the guidance of the light source is observed through the nasal endoscope, the brightness of the light source is adjusted through the button as required, and the needle insertion depth is observed through the needle body scales.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
