Description

Technical Field

[0001] The utility model relates to the technical field of endoscopes, in particular to an anti-fogging endoscope lens. Background Art

[0002] The existing endoscope lenses are prone to fogging due to the temperature difference between the lens and the human body, which makes the surgical field of view unclear, inconvenient for the surgeon, and affects the accuracy of the surgery. In order to solve the problem of fogging of endoscopes during surgery, surgeons generally use two methods to avoid it: one is to preheat the lens with hot saline before surgery, but the lens is a high-precision product, and long-term immersion in hot saline will cause damaging damage to the lens; the other method is to wipe the lens with iodine or alcohol before surgery. Although this method can solve the problem to a certain extent, alcohol and iodine are irritating substances that will irritate internal organs and tissues. Moreover, these two methods can only work for a short time. When the lens fogs up, the surgeon still needs to wipe the lens again to ensure that the lens does not fog up and the surgery can proceed normally, but this undoubtedly increases the time and difficulty of the surgery. Utility Model Content

[0003] In order to make up for the above shortcomings, the utility model provides an anti-fogging endoscope lens.

[0004] The utility model is achieved in this way:

[0005] A fogging-proof endoscope lens comprises a shell, a detection module and a heating module, wherein the shell comprises an outer shell, a first cavity is formed at the top of the outer shell, a second cavity and a third cavity are formed at the bottom of the first cavity, and the third cavity is annular and surrounds the second cavity, a second eyepiece and a first eyepiece connected to each other are provided in the first cavity, an annular metal sheet is installed at the bottom of the second eyepiece, the detection module is installed in the second cavity, the heating module is installed in the third cavity and heats the annular metal sheet in the air, and a temperature sensor is installed at the top of the detection module.

[0006] Furthermore, the heating module includes an annular protective shell, a heating wire, and an annular heating plate. The heating wire is installed inside the annular protective shell, the annular heating plate is installed on the top of the annular protective shell, and the heating wire heats the annular heating plate.

[0007] Furthermore, the detection module includes a cylindrical protective shell, a microprobe, and a plurality of LED lamp beads. The microprobe is embedded in the top of the cylindrical protective shell, and the plurality of LED lamp beads are evenly installed on the top of the cylindrical protective shell and surround the microprobe.

[0008] Furthermore, a cable is connected to the bottom of the shell, and the cable includes a communication line and a power supply line. The communication line is communicatively connected to the temperature sensor and the micro-probe, and the power supply line is electrically connected to the temperature sensor, the micro-probe, a plurality of LED lamp beads, and the heating wire.

[0009] The beneficial effect of adopting the above-mentioned further scheme is that after the endoscope enters the patient's body, the power supply line is used to power the micro-probe, several LED lamp beads, and the heating wire, so that the heating wire heats the annular heating plate, and then the annular heating plate heats the annular metal sheet in the air to increase the surface temperature of the second eyepiece and the first eyepiece to make it close to the patient's internal body temperature, thereby preventing fog from forming on the surface of the first eyepiece, and then the micro-probe that collects information inside the patient's body through the second eyepiece and the first eyepiece will not be affected by the fog, and the collected image will be sent to the display screen using the communication line. Secondly, several LED lamp beads are used to illuminate the surrounding tissues to improve the clarity of the image. Finally, because the center of the annular metal sheet is a circular hole, it will not hinder the collection of the micro-probe.

[0010] The beneficial effect of adopting the above further scheme is that the temperature inside the endoscope is collected by a temperature sensor, making it close to the patient's internal body temperature, while ensuring that fog is not generated and avoiding excessive temperature that may burn the tissue around the endoscope.

[0011] Furthermore, the first eyepiece is mounted on the top of the second eyepiece and covers the top of the shell, the top of the shell is connected with a cover plate, and the cover plate squeezes the edge of the first eyepiece.

[0012] Furthermore, the cover plate includes a connecting ring and a pressing ring, the pressing ring is installed on the top of the inner wall of the connecting ring, and the bottom of the pressing ring is in contact with the edge of the first eyepiece.

[0013] Furthermore, a thread groove is provided on the top of the shell, and the connecting ring and the thread groove are threadably engaged with each other.

[0014] The beneficial effect of adopting the above further scheme is that, by using the connecting ring connected by threaded engagement, when the first eyepiece and the second eyepiece need to be replaced, the connecting ring can be unscrewed. At this time, the pressure ring no longer squeezes the edge of the first eyepiece, and the user can therefore remove the first eyepiece and the second eyepiece to achieve the purpose of quickly replacing the first eyepiece and the second eyepiece.

[0015] The beneficial effect of the utility model is that the utility model obtains an anti-fogging endoscope lens through the above design, and heats the annular metal sheet through the heating module to increase the surface temperature of the second eyepiece and the first eyepiece to make them close to the patient's internal body temperature, thereby preventing fog from being generated on the surface of the first eyepiece, and further preventing the detection module that collects information inside the patient's body through the second eyepiece and the first eyepiece from being affected by the fog, thereby improving the detection effect and simplifying the operation steps.
