Detailed Description

In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, based on the examples herein, which are within the scope of the utility model as defined by the claims, will be within the scope of the utility model as defined by the claims.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

In various embodiments of the present application, "proximal" and "distal" refer to the location of the components relative to the user's far and near position in the environment of use, wherein the end closer to the user is designated as "proximal" and the end farther from the user is designated as "distal".

However, since the distal end of the first length of pull cord 331 and the proximal end of the second length of pull cord 332 are both movable, it is difficult to ensure that the pull cord 33 is always in a straightened state during assembly of the endoscope. For this reason, the present application provides an adjusting means at the proximal end of the insertion portion body 21, and by increasing the distance between the proximal end of the insertion portion body 21 and the dial 32, the second pulling rope 332 can be pulled to move away from the dial 32, thereby changing the pulling rope 33 from a relaxed state to a straightened state.

The adjusting assembly, the insertion portion and the endoscope provided by the embodiment of the application are described in detail below with reference to fig. 1 to 10 by means of specific embodiments and application scenarios thereof.

The first aspect of the present embodiment provides an adjustment assembly.

The adjusting portion 12 and the outer surface of the fixing portion 11 are not limited to be connected by a screw structure, but may be connected by the remaining structure. For example: the adjusting part 12 and the outer surface of the fixing part 11 can be connected through the matching of a buckle and a clamping groove.

According to a preferred embodiment, the inner diameter of the adjusting part 12 is not smaller than the outer diameter of the first fixing section 111, an adhesive layer is further provided between the adjusting part 12 and the first fixing section 111, and the adjusting part 12 and the first fixing section 111 are fixedly connected by the adhesive layer. Preferably, the adhesive layer may be a rubber layer having adhesiveness, and the adhesive layer may be injected between the adjusting portion 12 and the first fixing section 111 by means of glue filling. In the adjusting assembly 10 according to the preferred embodiment, by providing an adhesive layer between the adjusting portion 12 and the first fixing section 111, the reliability of the connection between the adjusting portion 12 and the first fixing section 111 can be ensured, and the problem that the distance between the proximal end of the insertion portion body 21 and the dial 32 is affected due to displacement of the adjusting portion 12 is avoided.

According to a preferred embodiment, the length of the first screw structure 111a in the axial direction of the fixing portion 11 is greater than the height of the adjusting portion 12 in the axial direction thereof, as shown in fig. 6. The height of the adjusting portion 12 in its axial direction refers to the height of the adjusting portion 12 in its own axial direction. In the adjusting assembly 10 according to the preferred embodiment, the length of the first thread structure 111a in the axial direction of the fixing portion 11 is greater than the height of the adjusting portion 12 in the axial direction thereof, so that the distance between the proximal end of the insertion portion body 21 and the dial 32 has a larger adjusting range, and the loose traction rope 33 can be adjusted to a straightened state.

According to a preferred embodiment, the adjustment portion 12 is of a hex bolt configuration, as shown in fig. 6-9. In the adjusting assembly 10 according to the preferred embodiment, the adjusting portion 12 has a hexagonal bolt structure, and the hexagonal bolt is a standard component, so that the adjusting portion 12 is easy to manufacture.

The endoscope has two handle housings 31, only one of which is shown in fig. 1 and 4. The two sides of the handle housing 31 refer to: one side of one of the handle cases 31 and one side of the other handle case 31 (instead of both sides of the same handle case 31). The two sides of the handle housing 31 are specifically shown as the upper and lower sides of the handle housing 31 in fig. 4 and 5, and fig. 4 and 5 show only the handle housing 31 on the lower side. According to the adjusting assembly 10 of the preferred technical scheme of the embodiment, when the adjusting part 12 is clamped with the handle shell 31, two edges 122 opposite to each other of the hexagonal bolt are respectively abutted with two sides of the handle shell 31, and the clamping depth of the hexagonal bolt and the handle shell 31 can be maximized due to the installation position of the hexagonal bolt, so that the clamping between the hexagonal bolt and the handle shell 31 is firmer.

Specifically, when the installation position of the adjusting portion 12 satisfies: when two edges 122 opposite to each other of the hexagon bolt are respectively abutted against two sides of the handle housing 31, the clamping depth of the adjusting part 12 and the handle housing 31 is H ₁, as shown in FIG. 8; when the installation position of the adjusting portion 12 satisfies: when the opposite surfaces of the hexagon bolt are respectively abutted against the two sides of the handle housing 31, the engagement depth between the adjusting portion 12 and the handle housing 31 is H ₂, as shown in fig. 9.
