Detailed Description

The following description provides many different embodiments, or examples, for implementing different features of the utility model. The elements and arrangements described in the following specific examples are presented for purposes of brevity and are provided only as examples and are not intended to limit the utility model.

In the embodiments of the present utility model, "proximal" and "distal" refer to the endoscope and its accessories in the use environment, with respect to the user's near-far position, wherein the end closer to the user is designated as "proximal" and the end farther from the user is designated as "distal".

In the related art of the endoscope, after the active bending section 600 enters the natural lumen of the human body, since the natural lumen is not straight but has a plurality of channels of bent and bent portions, it is necessary to control the bending angle of the active bending section 600 so that the active bending section 600 can smoothly move along the extending direction of the natural lumen; in the moving process of the active bending section 600, the distal end of the active bending section 600 inevitably contacts with human tissues, and the distal end of the active bending section 600 is generally provided with a front end seat, so that the front end seat contacts with the human tissues, and the front end seat is provided with a camera module 700, a light source 800, an instrument channel 400 and the like; because there are tissue fluid or mucus on the inner wall of human tissue, in the process of contacting the front end seat with human tissue, the lens surface of the camera module 700 inevitably adheres with some tissue fluid or mucus, which results in the influence of the imaging quality of the camera module 700 and also influences the normal judgment of doctors on the observed part.

In view of this, some embodiments of the present utility model provide a front end housing of an endoscope, which is applied to the endoscope as shown in fig. 1 to 7, and the shielding part 300 is provided to prevent the lens of the camera module 700 from contacting the inner wall of the tissue, so as to avoid the situation that the surface of the lens is stuck with tissue fluid.

The front end seat 100 of the endoscope provided by the utility model is provided with a camera module mounting hole 200 and an instrument channel 400, wherein the camera module mounting hole 200 is used for mounting a camera module 700, and the instrument channel 400 is used for mounting an instrument tube and is matched with an examination flow and a treatment flow in a medical procedure; the front-end socket 100 further has a shielding portion 300 extending toward the distal end thereof, and the shielding portion 300 is provided protruding toward the distal end thereof with respect to the camera module mounting hole 200, the shielding portion 300 being located in the circumferential direction of the camera module mounting hole 200 to protect the camera module mounting hole 200.

In specific use, the camera module mounting hole 200 is located behind the shielding part 300, after the active bending section 600 enters the human body cavity, as the shielding part 300 is firstly contacted with the inner wall of human body tissue, the shielding part 300 pushes away the human body tissue along with the advance of the active bending section 600, so that the contact between the human body tissue and the lens surface of the camera module 700 mounted in the camera module mounting hole 200 is avoided, and tissue fluid or mucus is generally adhered to the inner wall of the human body tissue in the natural cavity of the human body, therefore, by avoiding the contact between the inner wall of the human body tissue and the lens surface, the adhesion of tissue fluid or mucus on the surface of the lens is avoided, the problem of unclear imaging is avoided, and the imaging quality is improved.

The shielding part 300 can be positioned on the distal end face of the front end seat 100 or on the side wall of the front end seat 100, and only the shielding part 300 is required to be arranged towards the distal end in a protruding way relative to the camera module mounting hole 200, so that the shielding part 300 is ensured to contact human tissues before the camera module 700, and the human tissues are pushed away, and the camera module 700 is prevented from contacting the human tissues.

In the related art, after the mucus is attached to the lens surface, part of the product is sprayed to wash and clean the mucus on the lens surface by adopting a related means, so that the cleanness of the lens surface is maintained, but the structure of the means is complex, a pipeline related to spraying also occupies the space in the insertion tube of the endoscope, the diameter of the insertion tube is influenced, or the operation of other instruments is influenced, and compared with the spraying structure, the shielding part 300 is arranged, so that the structure of the shielding part 300 is simpler, the manufacturing and the production are convenient, and on the other hand, the space which is not occupied in the insertion tube is not too much, and the diameter of the insertion tube is not influenced.

In some embodiments, the light source mounting hole 500 is disposed on the shielding portion 300, and after the light source 800 is mounted to the light source mounting hole 500, the light source 800 is located at a distal end of the camera module 700, so as to avoid the light source mounting hole 500 from penetrating into the liquid and affecting the normal use of the light source 800, and a transparent lens is usually mounted on the surface of the light source 800 for waterproof; after the light source 800 emits light, when the optical fiber passes through the transparent lens, refraction and reflection occur, wherein the reflected light rays are transmitted towards the near end, if the interval between the lens of the camera module 700 and the light source 800 is relatively close, the light rays emitted by the transparent lens are easily transmitted to the position of the lens, so that the lens of the camera module 700 is over-exposed, in the prior art, a part of products are arranged between the camera module 700 and the light source 800 to avoid the over-exposure, however, in the embodiment, due to the arrangement of the shielding part 300, the light source mounting hole 500 is directly arranged on the shielding part 300, the over-exposure phenomenon of the lens of the camera module 700 can be avoided, and the distance between the light source 800 and the camera module 700 is increased after the light source 800 is mounted on the light source mounting hole 500 on the shielding part 300, so that the light rays reflected by the light source 800 are favorably prevented from being transmitted to the lens position of the camera module 700, and the over-exposure phenomenon is avoided.

It will be appreciated that the shielding part 300 in the present utility model may be a simple protrusion or may be an annular structure surrounding the camera module mounting hole 200, in some embodiments, the shielding part 300 may be an annular structure, and the shielding part 300 is disposed along the circumference of the camera module mounting hole 200, and as shown in fig. 2, each position of the circumference of the camera module mounting hole 200 has the shielding part 300, no matter in which direction the front end seat moves, the shielding part 300 blocks the distance between the inner wall of the human body and the camera module 700, so as to avoid adhesion of mucus on the lens of the camera module 700, however, in such a structure, the photographing range of the camera module 700 may be limited by the shielding part 300.

Therefore, in order to avoid or weaken the limitation of the shielding part 300 on the shooting range of the camera module 700, in some embodiments, a transparent shielding area 330 may be disposed in a partial area of the shielding part 300, the transparent shielding area 330 is transparent, and the shooting range of the camera module 700 is not affected, the transparent shielding area 330 is located at a position of the shielding part 300 away from the instrument channel 400, as shown in fig. 3, in the manufacturing process, in order to improve the structural stability of the shielding part 300, two-material injection molding may be directly adopted to form the shielding part 300 made of two materials, and in other embodiments, the position where the transparent shielding area 330 is disposed may also be directly disposed as the opening 340, and the shooting range of the camera module 700 is not affected; similarly, an opening 340 may be provided at a portion of the shielding portion 300 close to the instrument channel 400, and the opening 340 may be provided in communication with the instrument channel 400, as shown in fig. 4; the position of the opening 340 may also be set as a transparent occlusion region 330; in addition, the opening 340 and the transparent shielding region 330 may be separately provided, or may be simultaneously provided, and when the openings are simultaneously provided, the structure of the front end seat is shown in fig. 5.

The transparent shielding region 330 or the opening 340 is disposed at the position of the shielding portion 300 close to or far from the instrument channel 400, so that the structural stability of the shielding portion 300 can be increased, in order to avoid the increase of the diameter size of the front end seat, the shielding portion 300 is generally disposed on the distal end face of the front end seat, and the camera module mounting hole 200 and the instrument channel 400 on the front end seat need to be as compact as possible to reduce the diameter size of the front end seat, so that the area of the camera module mounting hole 200, which is not close to the instrument channel 400, is larger, and the structural stability of the shielding portion 300 at the position is better, so that the structural stability of the shielding portion 300 is greatly affected, and if the shooting range of the camera module 700 needs to be enlarged, the transparent shielding region 330 or the opening 340 is disposed at the position of the shielding portion 300 close to or far from the instrument channel 400.

No matter which position of the shielding part 300 is provided with the opening 340, the edge of the shielding part 300 close to the opening 340 needs to be in smooth transition with the far-end surface of the front-end seat 100, and as the shielding part 300 is arranged in a protruding manner, the structure of the transition part needs to be smooth and cannot be in a structure such as an edge angle or a folding angle, and the smooth structure can avoid the damage of the shielding part 300 to human tissues in the moving process.

In order to improve the photographing range of the photographing module 700, the shielding part 300 may be further provided as a transparent structural member, and each position of the shielding part 300 is transparent, but the transparent structural member has better reflection and transmission effects on light, so if the shielding part 300 is provided as a transparent structural member, it is necessary to pay extra attention to whether the photographing module 700 will be excessively exposed.
