Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a self-fixating anoscope. Background Art

[0002] An anoscope is a device or instrument used to examine rectal (anorectal) lesions. It is a commonly used tool for anorectal examinations and comes in two types: traditional anoscopes and electronic anoscopes. Traditional anoscopes are made of either disposable plastic or reusable stainless steel. Electronic anoscopes, on the other hand, are high-tech products that utilize cutting-edge medical video and camera technology to integrate both examination and treatment.

[0003] The patent document with application number 202110366154.2 discloses a disposable anoscope with a light source. The anoscope with a window for ligation and hemostasis includes a lens cover, the front end of the lens cover is connected to a trumpet mouth, an inner core is movably inserted in the lens cover, the lower part of the circumferential surface of the trumpet mouth is connected to an arc-shaped light-collecting cover, a light guide is provided on the rear inner wall of the arc-shaped light-collecting cover, and a mounting column is fixed to the front end of the light guide. The structure of the entire device is reasonably arranged and ingeniously conceived. By improving the internal structure of a common anoscope and adding an external light source, it not only greatly improves the line of sight during surgery but also does not increase the batch processing cost. The external light source is set to be recyclable, which greatly improves the practicality of the device.

[0004] However, in actual use, it was found that although this device solved the problem of the anoscope carrying a light source, the light source was fixed at the bottom of the bell mouth, which affected the lighting efficiency. If the light source was moved upward, it would interfere with the inner core. Therefore, how to develop a new self-fixing anoscope has become an urgent problem to be solved by technicians in this field. Summary of the Invention

DETAILED DESCRIPTION

[0032] like Figures 1 to 11 As shown, a self-fixing anoscope comprises a scope 1, a bell mouth 2 and an inner core 3. The bell mouth 2 is fixedly arranged at the front end of the scope 1, and the bell mouth 2 and the scope 1 are an integral structure. The bell mouth 2 and the scope 1 are both made of transparent material.

[0033] The inner core 3 is pluggable in the lens case 1, and a pull rod 301 is provided at the front end of the inner core 3. The lens case 1 is a hollow cylindrical structure with a gradually increasing aperture from the back to the front, and the inner core 3 matches the inner diameter of the lens case 1.

[0034] A first holder 202 is provided at the lower end of the bell mouth 2, and a first pull bar 7 is provided in the first holder 202 so as to be movable up and down. The first pull bar 7 passes upward through the first holder 202 and is connected to the bottom end of the mounting cover 501. A light source rod 5 is detachably provided in the mounting cover 501.

[0035] The first pull bar 7 is evenly distributed with several positioning protrusions 701 that cooperate with the first clamping seat 202. The distance between two adjacent positioning protrusions 701 is the same as the length of the first clamping seat 202. The positioning protrusions 701 cooperate with the first clamping seat 202 to provide greater stability for the mounting cover 501. During use, the mounting cover 501 and the light source rod 5 can be adjusted vertically by pulling the first pull bar 7 up and down, providing greater flexibility and convenient operation from the outside of the bell mouth 2. This avoids the need to adjust the position of the mounting cover 501 and the light source rod 5 within the confined space of the bell mouth 2.

[0036] In the initial state of the device, the mounting cover 501 is located at the lowermost end of the bell mouth 2 to avoid interference with the inner core 3 .

[0037] Furthermore, the left end of the mounting cover 501 is provided with a second pull bar 8, and the right end of the mounting cover 501 is provided with a third pull bar 9. The bell mouth 2 is provided with a second clamping seat 203 that cooperates with the second pull bar 8, and the bell mouth 2 is provided with a third clamping seat 204 that cooperates with the third pull bar 9.

[0038] During use, the positions of the mounting cover 501 and the light source rod 5 can be adjusted in the left and right directions by pulling the second pull bar 8 and the third pull bar 9 left and right, further improving the flexibility of the device.

[0039] The mounting cover 501 of the self-fixing anoscope of the present invention is set on the bell mouth 2 through three adjustable pull strips, thereby realizing the adjustment of the position of the mounting cover 501, avoiding conflict with the inner core 3 and also facilitating the adjustment of the position of the light source rod 5, thereby achieving better lighting effect.

[0040] An arc-shaped plate 201 is fixedly provided at the front end of the mirror sleeve 1, a slider 4 is slidably provided on the arc-shaped plate 201, a reflector plate 401 cooperating with the light source rod 5 is provided at the front end of the slider 4, and several reflective protrusions cooperating with the light from the side wall of the light source rod 5 are provided on the reflector plate 401, and the angle of the reflective protrusions is 30° to 60°.

[0041] Specifically, the top of the mounting cover 501 is provided with an arc opening with a central angle of 120 degrees. The central angle of the arc plate 201 is 120 degrees, and the arc plate 201 corresponds to the arc opening of the mounting cover 501. The central angle of the slider 4 is 30 degrees.

[0042] During use, the light from the rear end of the light source rod 5 is used to illuminate the rear end of the eyeglass case 1, facilitating the doctor's operation. If necessary, a reflector plate 401 can be installed on the curved plate 201. The reflector plate 401 can reflect the light emitted by the light source rod 5 through the arc opening of the mounting cover 501 to the rear end of the eyeglass case 1, forming an enhanced light spot and further enhancing the lighting effect. The position of the reflector plate 401 can be adjusted by the slider 4, thereby adjusting the position of the enhanced light spot, making the use more flexible.

[0043] An arcuate groove for slidingly cooperating with the arcuate plate 201 is provided on the rear end surface of the slider 4. The slider 4 is detachably cooperating with the arcuate plate 201 through the arcuate groove and does not need to be installed when not necessary.

[0044] The outer circumference of the lens case 1 is provided with a positioning ring 6, and the left and right sides of the positioning ring 6 are provided with fixing lugs 601. The fixing lugs 601 are provided with fixing holes 602 for engaging with the binding wire. The outer circumference of the lens case 1 of the self-fixing anoscope of the present invention is provided with a positioning ring 6, which has a certain degree of elasticity and is fixed to the patient's thigh through the fixing lugs 601, thereby achieving self-fixation of the anoscope.

[0045] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
