In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; may be mechanically coupled, may be electrically coupled or may be in communication with each other; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Referring to fig. 1 and 2, the present invention provides a visual medical device, which includes an operation tube body and a light guide unit, wherein the operation tube body 1 is provided with a camera shooting cavity 11 for accommodating a camera shooting assembly, and the camera shooting cavity 11 extends from a proximal end to a distal end; the light guide unit 2 is configured on the visual medical instrument, the light guide unit is configured to be capable of conducting light to the far end of the imaging cavity, and the light guide unit comprises a light guide member 2.
Through the visual medical instrument provided by the invention, the camera shooting cavity provided by the invention provides a bright environment under the action of the light emitting piece such as the LED lamp, the camera shooting assembly is not required to be configured with the LED lamp, and the accommodating size of the camera shooting assembly is reduced, so that the visual medical instrument can reduce the size of the cavity provided for the camera shooting assembly on the visual medical instrument and provides possibility of enlarging the size of other operation channels; in addition, the LED lamp provided by the existing camera shooting component is limited by the size of the camera and has small power.
There are many ways to implement the light guide unit, and those skilled in the art can choose various forms as long as they can provide light for the camera module;
in some embodiments, referring to fig. 1 and fig. 2, a light guide wire 2 is embedded in the operation tube body 1, and extends from the proximal end to the distal end, so that the light guide wire transmits light to the camera module at the distal end by being irradiated by an external light source;
in other embodiments, at least a portion of the operating tube is made of a catheter material to form a light guide, such that the tube itself forms the light guide to transmit light from the light source; specifically, referring to fig. 3, in the present embodiment, the circumferential wall of the camera cavity is made of a light guide material to form a light guide.
It can be understood that the light guide member has a light incident surface facing the light emitting member and a light emergent surface facing the far end of the camera cavity.
Specifically, at least one operation channel (not shown) is further provided inside the operation tube body 1, and the operation channel is spaced from the imaging cavity, and the operation channel includes, but is not limited to, the following channels: the size of the camera cavity can be reduced significantly by the light guide provided by the invention, and thus the size of the channel can be operated.
In this embodiment, the operation channel is separated from the camera cavity, and referring to fig. 1, the camera cavity has an inlet for inserting and pulling the camera assembly therein, and the distal end of the camera cavity is sealed by a transparent lens, so that the contact between the camera assembly and the body fluid of the patient can be blocked.
It can be understood that the operation channel and the camera shooting cavity can be overlapped to form a channel, and can also be arranged in a separated mode; when the operation channel and the camera cavity can be overlapped to form a channel, referring to fig. 4, the camera assembly can be accommodated in the channel through the lens sleeve 3, and the distal end of the lens sleeve is provided with the sealing lens 31.
The embodiment also provides a camera assembly accommodated in the camera cavity, the camera assembly comprises a camera and a connecting wire, namely, a light source part such as an LED light source is not required to be arranged, one end of the connecting wire is connected with the camera, the other end of the connecting wire is used for being connected with a display device, the light guide unit provides light to the camera,
the existing camera shooting component (also called as a visual device) is provided with an LED light source and a camera at the same time, so that the radial size of the camera shooting component is larger than 2.1mm, and a visual channel matched with the camera shooting component needs to be larger than 2.2 mm; through the visual medical instrument provided by the invention, the radial dimension of the visual device is reduced to 1.0-1.6mm without being equipped with an LED light source, and meanwhile, the radial dimension of a visual channel matched with the visual device is reduced to 1.1-1.7mm from the existing 2.2mm or so, in the embodiment, the radial dimension of the camera shooting component is reduced to 1.1mm, and the inner diameter dimension of the visual channel is 1.2mm, so that the sizes of the camera shooting component and the camera shooting cavity are obviously reduced, and a larger operation space is reserved for other operation channels.
In addition, due to the limitation of medical operation environment, the smaller the diameter of the camera assembly is, the more convenient the operation of the doctor is,
furthermore, the problem of light reflection is serious when an LED at the front end of the visual device emits light clinically at present, and the smaller the diameter of the visual device is, the larger the distance between the camera shooting assembly and the light source is, the more difficult the light reflection phenomenon is to occur; according to the visual medical instrument provided by the invention, the light source is arranged near the visual medical instrument, the distance between the camera and the light source is far away, the phenomenon of light reflection hardly exists, and the imaging effect is better.
By the aid of the camera shooting assembly, operating space is enlarged in a visual environment, the camera shooting assembly suitable for the visual medical instrument is not provided with an LED lamp, the diameter of the camera shooting assembly is effectively reduced, and a light source is put into the instrument, so that the light environment of an observation end can be realized.
The invention also provides a camera component, which can omit the combined development link of a camera and an LED, can realize the same light environment as the existing visual device and save the cost.
