[0002] An endoscope is a medical device mainly used for examining and treating internal organs and cavities of the human body. An endoscope consists of a slender flexible tube, a light source, a camera and other auxiliary instruments. Through the endoscope, a doctor can enter the body through a natural orifice or a small incision for diagnosis, sampling and some minimally invasive surgeries. The lens tube of the endoscope is one of the core components of the endoscope, mainly responsible for transmitting light and images. The lens tube is usually made of flexible or rigid materials and contains multiple components to achieve its functions.

[0003] At present, when the lens tube for an endoscope system used in the medical field is connected to external devices, it is mostly connected to external display devices and operating devices by direct plugging. In fact, the specifications and sizes of the lens tube insertion interfaces of different external devices are also different. Therefore, different lens tubes need to be replaced, that is, one lens tube can only be connected to external devices with corresponding specifications and cannot be applied to multiple different specifications of insertion interfaces.

[0024] Embodiment

[0025] Referring to Figure 1 - Figure 2 , an embodiment of the present utility model provides a lens tube for an endoscope system, including: a lens tube unit 100 and an adjusting and tightening unit 200.

[0026] Among them, the lens tube unit 100 includes a tube body 101 and a connecting portion 102 fixedly connected to the tank body. One end of the connecting portion 102 away from the tube body 101 is fixedly connected with a socket 103, and a socket cover 104 is fixedly connected to the edge of one end of the socket 103 away from the connecting portion 102;

[0027] Secondly, the adjusting and tightening unit 200 includes a plurality of rectangular sliders 201 slidably arranged inside the socket 103. A rectangular sliding cavity 202 matching the rectangular slider 201 is arranged inside the socket 103. Strip-shaped openings communicating with the rectangular sliding cavity 202 are opened on both sides of the socket 103, and the width of the strip-shaped opening is smaller than the thickness of the rectangular slider 201. One end of the rectangular slider 201 away from the connecting portion 102 is fixedly connected with a tightening plate 204 through a connecting rod 203. Each tightening plate 204 is arranged in an arc shape, and a corresponding positioning protrusion 205 is fixedly connected to the center of the outer side wall of the tightening plate 204. Through the setting of the positioning protrusion 205, the tightening and plugging effect between the tightening plate 204 and the lens tube socket is enhanced, and the connecting rod 203 sequentially passes through the strip-shaped opening and the socket cover 104. Each connecting rod 203 is arranged in an L shape and is made of austenitic stainless steel. The connecting rod 203 made of austenitic stainless steel not only has strong anti-rust ability but also can meet the strength use requirements. The adjusting and tightening unit 200 further includes a tightening driving component 206 for tightening the tightening plate 204.

[0028] Next, the tightening drive assembly 206 includes a sliding sleeve 206a slidably sleeved on the connecting portion 102 and a positioning cover 206d fixedly connected to the sliding sleeve 206a. One end of the rectangular slider 201 away from the connecting rod 203 is fixedly connected with a strip-shaped slider, and the strip-shaped slider penetrates through the strip-shaped opening. Each strip-shaped slider and the sliding sleeve 206a are hinged through a corresponding hinge arm 206c. One end of the strip-shaped slider away from the rectangular slider 201 is fixedly connected with a first hinge seat, and a plurality of second hinge seats are fixedly arranged on the sliding sleeve 206a. Each first hinge seat and the second hinge seat are hinged through a hinge arm 206c. A positioning bolt 206e is threadedly connected to the positioning cover 206d. Each positioning bolt 206e penetrates through the positioning cover 206d and abuts against the outer side wall of the connecting portion 102. A positioning groove 206f corresponding to the positioning bolt 206e is formed on the side wall of the connecting portion 102, and the positioning bolt 206e penetrates through the positioning cover 206d and abuts tightly against the inner wall of the positioning groove 206f. Through the setting of the positioning groove 206f, the positioning effect of the positioning bolt 206e on the positioning cover 206d is improved, and further, the positioning bolt 206e firmly positions the position of the sliding sleeve 206a on the connecting portion 102.

[0029] During the use process, when it is necessary to connect the lens tube to the external device insertion port, move the sliding sleeve 206a according to the inner diameter of the insertion port. The rectangular slider 201 hinged to the sliding sleeve 206a through the hinge arm 206c moves in the rectangular sliding cavity 202, and the connecting rod 203 fixedly connected to the rectangular slider 201 drives the tightening plate 204 to move radially along the insertion cover 104. When the tightening plate 204 abuts against the inner wall of the insertion port, at this time, tighten the positioning bolt 206e, and the tightening plate 204 tightly abuts against the inner wall of the insertion port, so as to realize that a lens tube can adapt to a variety of different external devices and be firmly connected to insertion ports of various different specifications.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
