It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0061] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0062] Unless otherwise specified, the exemplary embodiments / embodiments shown will be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various embodiments / embodiments can be combined, separated, interchanged and / or rearranged without departing from the technical concept of the present disclosure.

[0063] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0064] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0065] For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "down," "over," "upper," "above," "higher," and "side (e.g., in a "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings.

[0068] like Figure 1 As shown, the adapter 100 for the endoscope system includes: a first cylinder 106, the first cylinder 106 is used to accommodate an optical lens; a second cylinder 105, a sealed space is formed inside the second cylinder 105, and the first cylinder 106 is arranged in the sealed space; an adjusting knob, the adjusting knob is arranged outside the second cylinder 105, and the contact between the second cylinder 105 and the adjusting knob is smooth; a first magnet 103, the first magnet 103 is arranged inside the adjusting knob; and a second magnet 104, the second magnet 104 is arranged on the outer wall surface of the first cylinder 106; when the adjusting knob rotates, the magnetic force between the first magnet 103 and the second magnet 104 drives the first cylinder 106 to move inside the second cylinder 105.

[0069] Figure 1 Schematically showing that a plurality of optical lenses are housed in the first cylinder 106 .

[0070] Figure 2 1 is one of the schematic diagrams of the radial cross-sectional structure of the adapter 100 for the endoscope system according to one embodiment of the present disclosure. Figure 2 A preferred configuration of the first magnet 103 and the second magnet 104 is shown.

[0072] The second barrel 105 is the connecting body of the entire adapter, which can be assembled together with the endoscope connecting mechanism and the camera system connecting mechanism.

[0073] The contact between the second cylinder 105 and the adjusting knob (preferably composed of the knob outer cylinder 101 and the knob inner cylinder 102) is smooth contact, or described as non-damping contact. The purpose of this arrangement is to avoid optical jitter when the adjusting knob is rotated.

[0074] The first magnet 103 may be embedded inside the adjusting knob so that the first magnet 103 does not contact the second cylinder 105 .

[0075] The second magnet 104 is arranged on the outer wall surface of the first cylinder 106. Preferably, a recess is formed on the outer wall surface of the first cylinder 106. The second magnet 104 is arranged in the recess formed on the outer wall surface of the first cylinder 106, and the second magnet 104 does not contact the inner wall surface of the second cylinder 105.

[0076] When the adjusting knob is rotated, the magnetic force (preferably attractive force) between the first magnet 103 and the second magnet 104 drives the first cylinder 106 to move in the second cylinder 105 along the axial direction of the adapter.

[0077] Preferably, the adjustment knob of the adapter 100 for the endoscope system includes a knob outer cylinder 101 and a knob inner cylinder 102 , and the first magnet 103 is fixed between the knob outer cylinder 101 and the knob inner cylinder 102 .

[0078] like Figure 1 As shown, a cavity for accommodating the first magnet 103 is formed between the knob outer cylinder 101 and the knob inner cylinder 102. Those skilled in the art should understand that the cavity is an annular cavity.

[0079] Preferably, the inner wall surface of the second barrel 105 of the adapter 100 for the endoscope system is threadedly matched with the first barrel 106 .

[0080] More preferably, the outer wall surface of the first cylinder 106 of the adapter 100 for the endoscope system is formed with a recess, and the second magnet 104 is arranged in the recess; the inner wall surface of the second cylinder 105 is configured with an internal thread, and the outer wall surface of the first cylinder 106 is configured with an external thread, and the internal thread and the external thread are meshed with each other.

[0081] By meshing the external transmission thread arranged on the outer wall surface of the first barrel 106 with the internal transmission thread arranged on the inner wall surface of the second barrel 105, the movement of the first barrel 106 in the second barrel 105 driven by magnetic force is more stable, further avoiding optical jitter.

[0084] The second end cap 115 can be fixedly connected to the second end of the second cylinder 105. The second end cap 115 can be circular and have an opening in the middle. The circular outer end of the second end cap 115 can be fixedly connected to the second end of the second cylinder 105 by welding, such as laser welding.

[0085] The first optical window 111 is an optical protection window, which may be circular in shape and allows light to pass through, for example, allows light from an endoscope to pass through and enter the lens. The first optical window 111 is disposed at the opening of the first end cap 112 and may be fixed to the first end cap 112 by gluing or brazing.

[0086] The second optical window 116 is an optical protection window, which may be circular in shape and allow light to pass through, for example, allow light from the lens to enter the camera system. The second optical window 116 may be disposed at the opening of the second end cap 115 and may be fixed to the second end cap 115 by gluing or brazing.

[0087] Through the above structure, the second barrel 105 is assembled with the first end cap 112 and the second end cap 115 with strict tolerance, and then fixed together by processes such as welding, so that the second barrel 105, the first end cap 112, the second end cap 115, the first optical window 111 and the second optical window 116 form a strict and reliable sealed space for the optical lens assembly (including the first barrel 106 and the lens arranged in the first barrel 106). When the adapter 100 is sterilized by high temperature and high pressure steam, this sealed space will protect the internal optical lens assembly from any damage. More preferably, the sealed space is filled with inert gas.

[0091] The first end seat 110 is used to connect the adapter 100 to the camera device. Figure 1 As shown, a connection structure such as a standard threaded interface for connecting with the camera device is formed on the outer periphery of the first end seat 110 .

[0092] The first retaining ring 109 is connected to the second cylinder 105 by threaded engagement, and then a moderate damping force is given to the first end seat 110 by squeezing the second elastic body 108, so that the first end seat 110 can be firmly and reliably assembled on the second cylinder 105, and the first end seat 110 can be rotated in the radial direction. When in use, the flange on the first end seat 110 can be held by hand ( Figure 1 The first end seat 110 has a flange structure and can be rotated 360 degrees relative to the adapter axis.

[0093] Preferably, the adapter 100 for an endoscope system disclosed herein further comprises a second end seat, which is disposed at the second end of the second cylinder 105 and is used to connect the adapter 100 to the endoscope.

The two long slot holes 1141 of the cover portion 114 are arranged opposite to the two long slot holes 1131 of the connecting cylinder 113. The two long slot holes 1141 of the cover portion 114 are used to limit the travel range of the push plate 1170 instead of allowing the push plate 1170 to move freely at will. This travel range is not particularly limited in the present disclosure, and those skilled in the art can adjust it according to actual conditions.

[0100] Preferably, if Figure 5As shown, a second protrusion 1175 is also formed at the end of each arm portion 1172, and the second protrusion 1175 is confined in the long slot hole 1141 of the cover portion 114, thereby limiting the stroke of the push plate 1170; wherein, the first protrusion 1171 and the second protrusion 1175 on each arm portion 1172 are arranged opposite to each other.
