OCT probe used for human open lumen system

Abstract

The invention discloses an OCT probe used for human open lumen system, comprising a probe protector, a probe body, an oily liquid, a metal coil, a probe guard tip and a light-guided optical fiber; the probe body is match mounted will the metal coil, and the metal coil is mounted on the rear end of the probe body; the light-guided optical fiber is fixed inside the probe body; the probe guard tip is sleeved on the probe body, the probe protector is sleeved on the probe guard tip and sleeved on the metal coil; the oily liquid is filled between the probe guard tip and the probe protector, and between the metal coil and the probe protector. The invention effectively remedy for the defect that the image is unclear by filling the oily liquid between the probe protector and the probe body.

Claims

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a schematic view showing the structure of an OCT probe used for human open lumen system according to the present invention.

(2) Reference numerals: 1, probe protector; 2, probe body; 3, oily liquid; 4, metal coil; 401, connecting stator; 5, probe guard tip; 6, light-guided optical fiber; 7, fixing member.

DESCRIPTION OF EMBODIMENTS

(3) Hereinafter, the present invention will be further described in conjunction with the drawings and specific embodiments:

(4) As shown in FIG. 1, the embodiment provides an OCT probe used for human open lumen system, comprising a probe protector 1, a probe body 2, an oily liquid 3, a metal coil 4, a fixing member 7, a connecting stator 401, a probe guard tip 5, and a light-guided optical fiber 6, the probe body 2 is match mounted with the metal coil 4, and the metal coil 4 is mounted on the rear end of the probe body 2, the light-guided optical fiber 6 is fixed inside the probe body 2, and the fragile optical fiber can be effectively protected by the probe body 2, and the connecting stator 401 is used to fix the metal coil 4 and the light-guided fiber 6. It can be rotated and translated synchronously with the light-guided optical fiber by the torque of the metal coil 4 transmitting by the connecting stator 401, so that the probe is more smoothly and smoothly used. The human open lumen system (or lumen)mentioned in this embodiment may comprises the respiratory tract, the genital tract, the anorectal tract, the esophagus, the ear canal, the urethra, the uterine cavity, the gastral cavity, the oral cavity, etc., these are merely illustrative examples and not all of the open lumen system of the human body are listed.

(5) The probe guard tip 5 is sleeved on the probe body 2, and the probe guard tip 5 is a medical stainless steel probe guard tip. The fixing member 7 is used to fix the probe body 2 to the probe guard tip 5. The fixing member 7 is a medical plastic fixing member or a medical stainless steel fixing member. The probe protector 1 is sleeved on the probe guard tip 5 and the metal coil 4, and the probe protector 1 is a medical round nylon flexible tube. The front end of the probe protector 1 is hemispherical, and the outer diameter of the probe protector 1 is less than or equal to 3 mm and the oily liquid 3 is filled between the probe guard tip 5 and the metal coil 4 and the probe protector 1. The oily liquid 3 has the same refractive index as the probe protector 1. When they have the same or similar refractive index, the light exits will not cause the deflection of the light on account to the difference in refractive index, that will not result the circumstance of image unclear when there is no oily liquid 3, the image would be unclear. And the oily liquid has the characteristics of colorless, transparent, non-toxic, and low viscosity, which further ensures the clarity of the transmitted image.

(6) Various other changes and modifications may be made by those skilled in the art in light of the above-described technical solutions and concepts, and all such changes and modifications are intended to fall within the scope of the appended claims.
