Description

Technical Field

[0001] The utility model relates to a light beam interface device for a handle of an electronic anorectal examination mirror, belonging to the field of electronic anorectal examination mirrors. Background Art

[0002] Electronic anorectal examination mirror is a device or instrument used to examine rectal or anal lesions. It is a commonly used tool for anorectal disease examination. It can be used to detect lesions near the anal canal, rectal end and dentate line, and can also perform biopsy.

[0003] It is used in conjunction with an electronic anorectal examination scope handle and a matching anorectal ligation device or a disposable anoscope. An interface for guiding the light beam is provided at the bottom of the horizontal part of the electronic anorectal examination scope handle, so that the light beam can be introduced along the interface and then guided into the anorectal ligation device or the disposable anoscope, providing sufficient light for convenient observation of the tissue inside the rectum.

[0004] The interface of the rigid anoscope is circular, that is, the interface ends that provide lighting for the rigid anoscope on the current market are all circular pipes, and the notch on the handle of the electronic anorectal examination mirror corresponding to the rigid anoscope is also circular, with no room for movement. Therefore, when installing the rigid anoscope, it is difficult for the rigid anoscope to be stuck into the interior of the handle of the electronic anorectal examination mirror when it cooperates with the interface of the handle of the electronic anorectal examination mirror, which can easily cause interference.

[0005] Therefore, the utility model provides a light beam interface which is convenient for taking and placing an anoscope and a hard tube mirror and does not cause travel interference. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a light beam interface which is convenient for taking and placing an anoscope and a hard tube endoscope and does not cause travel interference.

[0007] The utility model is achieved in this way:

[0008] A light beam interface for an electronic anorectal examination scope handle, comprising a first shell and a second shell, wherein the first shell and the second shell are engaged to form a complete handle shell, wherein the handle shell comprises a horizontal portion and an inclined portion for hand holding;

[0009] A light beam interface is provided on the bottom surface of the horizontal portion of the handle housing;

[0010] The constraint ring is accommodated in the light beam interface, and the constraint ring is engaged with the handle shell, and the connecting tube of the anoscope rigid tube is accommodated in the constraint ring, and the inner diameter of the constraint ring is greater than the outer diameter of the connecting tube.

[0011] As a further improvement, the restraint ring comprises an annular body, bosses are provided on two planes of the annular body, and the bosses and the annular body are an integrated structure.

[0012] As a further improvement, the annular body is elliptical.

[0013] As a further improvement, the horizontal length L of the annular body is greater than the outer diameter of the connecting pipe.

[0014] As a further improvement, the outer diameter of the boss is smaller than the outer diameter of the annular body.

[0015] As a further improvement, the arc surface of the outer wall of the annular body has a straight cut.

[0016] The beneficial effects of the utility model are:

[0017] ① The utility model facilitates the installation and removal of the connection tube of the anoscope through the arrangement of the constraint ring and the beam interface on the handle shell; after the connection tube is installed in the constraint ring, it also has a horizontal travel range to provide the connection tube with horizontal movement space, so as to facilitate the horizontal end of the anoscope to match the internal structure of the handle shell. When removing the connection tube of the anoscope, the horizontal end of the anoscope is first separated from the internal structure of the handle shell, and when separating, the connection tube can move horizontally on the constraint ring, and finally the connection tube is separated from the constraint ring.

[0018] ② The horizontal length L of the annular body of the utility model is greater than the outer diameter of the connecting tube, ensuring that the connecting tube of the anoscope has a travel range when being disassembled or installed inside the annular body, thereby avoiding installation interference problems.

[0019] ③ The first shell and the second shell of the utility model are both double-layer structures, ensuring that the constraint ring will not move around when the first shell and the second shell are separated. At the same time, the constraint ring is stuck between the double-layer structures and is not easy to conflict with the structure inside the horizontal part of the handle shell. When disassembling and assembling the anoscope, it will not fall off the handle shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The light beam interface 30 is provided on the bottom surface of the horizontal portion of the handle housing;

[0030] The constraint ring 40 is accommodated in the light beam interface 30 , and the constraint ring 40 is engaged with the handle shell, and the connecting tube 50 of the anoscope rigid tube is accommodated in the constraint ring 40 , and the inner diameter of the constraint ring 40 is greater than the outer diameter of the connecting tube 50 .

[0031] The connecting tube 50 of the anoscope hard tube endoscope described here is an external light source of other devices, and the other devices include but are not limited to the light source of the console.

[0032] The utility model facilitates the installation and removal of the connection tube 50 of the anoscope hard tube mirror through the arrangement of the restraining ring 40 and the light beam interface 30 on the handle shell;

[0033] After the connecting tube 50 is installed in the restraining ring 40, a horizontal travel range is provided to provide the connecting tube 50 with space for horizontal movement, so as to facilitate the matching between the horizontal end of the anoscope and the internal structure of the handle shell.

[0034] Take out the connecting tube 50 of the anoscope, and first separate the horizontal end of the anoscope from the internal structure of the handle shell. When separating, the connecting tube 50 can move horizontally on the restraining ring 40, and finally separate the connecting tube 50 from the restraining ring 40.

[0035] The horizontal end of the anoscope and the connecting tube 50 in the vertical direction are installed without interfering with each other.

[0036] Specifically, the restraint ring 40 comprises an annular body 401 , on two planes of the annular body 401 , bosses 402 are provided, and the bosses 402 and the annular body 401 are an integrated structure.

[0037] Furthermore, the annular main body 401 is elliptical, and there are no dead angles on both sides of the annular main body 401, so dust is not easily accumulated and there is no collision with the connecting tube 50 of the anoscope rigid tube endoscope.

[0038] As a possible specific implementation of the utility model, the horizontal length L of the annular body 401 is greater than the outer diameter of the connecting tube 50, ensuring that the connecting tube 50 of the anoscope has a travel range when being disassembled or installed inside the annular body 401, thereby avoiding installation interference problems.

[0041] It ensures that the restraint ring 40 will not move around when the first shell 10 and the second shell 20 are separated. At the same time, the restraint ring 40 is stuck between the double-layer structure and is not easy to conflict with the structure inside the horizontal part of the handle shell. When disassembling the anoscope, it will not fall off the handle shell.

[0042] As a possible specific implementation of the present invention, the outer wall arc surface of the annular body 401 has a straight cut to avoid interference with the internal structure of the horizontal part of the handle shell.
