[0015] Furthermore, the outer wall of the lens is provided with a groove, and the interior of the groove is provided with an opening.

[0016] Furthermore, the inclination angle of the lens is 45 degrees.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] An opening is opened on the outer wall of the lens, and the lens is placed obliquely inside the lens, so that the lens can be cleaned through the opening without affecting the surgical use and without having to pull out the lens;

[0019] The mirror tube body and lens are detachable, which is convenient for disassembly, replacement and maintenance. At the same time, the card cover design makes the connection between the two more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Example

[0024] See also Figure 1-3 , the utility model provides a technical solution:

[0025] A laparoscope exploration lens comprises a lens tube body 2 and a lens 4, wherein a connecting ring 201 is arranged at one end of the lens tube body 2, and a fixing ring 401 detachably connected to the connecting ring 201 is arranged at one end of the lens 4 close to the connecting ring 201, so as to facilitate connecting the lens tube body 2 and the lens 4 together to form a whole;

[0026] In order to stabilize the connection, a clamping cover 3 for locking the connecting ring 201 and the fixing ring 401 is provided on the mirror tube body 2;

[0027] A lens cavity 8 is provided inside the lens 4, and a lens 5 is obliquely installed inside the lens cavity 8. Meanwhile, an opening 7 for cleaning the lens 5 is provided on the outer wall of the lens 4, so that cleaning is convenient without pulling out the lens 4.

[0028] like Figure 1 As shown: a connector 1 connected to an external pipeline is provided on the scope tube body 2, which facilitates the entire laparoscopic exploration and is displayed on the screen in real time.

[0029] like Figure 3 As shown: a raised ring 202 is provided on the connecting ring 201, so that the raised ring 202 is connected to the inner thread of the fixing ring 401, so as to realize a detachable connection, which is convenient for maintenance, replacement and use.

[0030] like Figure 2 As shown: a notch 302 for clamping the connecting ring 201 and the fixing ring 401 is provided at the bottom end of the card cover 3, and the notch 302 is used to lock the connecting ring 201 and the fixing ring 401 for stable connection. A fixing screw 301 is arranged on the card cover 3, so that the fixing screw 301 is threadedly connected to the mirror tube body 2, and is used to lock the connecting ring 201 and the fixing ring 401.

[0031] like Figure 1 As shown: a groove 6 is provided on the outer wall of the lens 4, and an opening 7 is provided inside the groove 6 to communicate with the lens cavity 8. For the convenience of cleaning, the lens 5 is tilted at an angle of 45 degrees to match the opening 7.

[0032] Working principle:

[0033] During use, the lens 5 can be cleaned through the opening 7. Since the lens 5 is inclined at 45 degrees, it is easy to clean. There is no need to take out the lens 4 during surgery, which is convenient and simple.

[0034] When it is necessary to replace parts, the fixing screw 301 is screwed out to separate the card cover 3 from the mirror tube body 2. At this time, the notch 302 loses the locking effect of the docking ring 201 and the fixing ring 401. At this time, the docking ring 201 and the fixing ring 401 can be separated by twisting, so as to be disassembled for easy maintenance and replacement.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
