Description

Technical Field

[0001] This application belongs to the technical field of anorectal surgical medical devices, and particularly relates to an anoscope for positioning and quantifying the treatment of hemorrhoids. Background Art

[0002] In the field of anorectal surgery, as an important tool for assisting surgeries, anoscopes come in a wide variety, including but not limited to barrel-shaped anoscopes, two-leaf, three-leaf, four-leaf, trumpet-shaped, straight-tube, bevel-mouth, edge-lacking, and U-shaped anoscopes, and are subdivided into different large, medium, and small models according to the specific conditions of patients. These traditional anoscopes play a certain role in assisting hemorrhoid resection surgeries, but they have significant limitations. Specifically, traditional anoscopes are difficult to stably fix around the anus during surgeries. Usually, additional assistants are required to assist in fixing or frequently adjust their positions to fully expose the hemorrhoid tissue. This process not only increases the complexity of the surgical operation but also may lead to difficulties in simultaneously positioning multiple hemorrhoids to be excised, and even accidentally injure the surrounding normal anal canal tissue due to insufficient exposure, thereby increasing the risk of surgical secondary injuries and the incidence of postoperative anal canal stenosis complications.

[0003] To address the above problems, there have been some innovative attempts, such as the "open-hole adjustable anoscope" disclosed in the Chinese utility model patent with the publication number CN216675708U. This design aims to improve the visual field exposure through an adjustable open-hole design. However, in actual applications, it is still limited by the number and position of the windows, making it difficult to achieve multi-point synchronous precise positioning and quantitative resection, which may lead to over-resection of the normal tissue around the hemorrhoid nucleus. In addition, this design has a relatively complex structure, which not only increases the manufacturing cost but also poses challenges to its wide application in clinical practice.

[0004] Another Chinese utility model patent with the publication number CN214907463U proposed an "anoscope device for stapled hemorrhoidopexy surgery", which achieved the fixation around the anus through a "limiting sticker ring", improving the stability during the surgery. However, this design still has deficiencies in positioning and quantitatively displaying hemorrhoid tissue and fails to fully meet the requirements of surgical precision and reducing secondary injuries. Utility Model Content

[0005] In order to overcome the defects that the existing technology cannot simultaneously take into account the fixation of the anoscope and multi-point positioning and quantification during the process of using an anoscope to assist in the surgical resection of hemorrhoids, the present utility model provides an anoscope for positioning and quantifying the treatment of hemorrhoids, which can effectively solve these defects.

[0006] To achieve the above application purpose, the technical solution adopted in this application is as follows:

[0007] An anoscope for positioning and quantitatively treating hemorrhoids provided by an embodiment of the present application includes a mirror body, a mirror tail, an inner core body part of the mirror body, a head of the inner core of the mirror body, and a baffle of the inner core of the mirror body. The mirror body is cylindrical and hollow. Along the long axis direction of the mirror body, six operation windows are opened on the mirror body from the rear end of the mirror body to the front end of the mirror body. The width of each operation window is one-twelfth of the circumference of the mirror body. The mirror tail is integrated with the mirror body and expands in a trumpet shape along the rear end of the mirror body. An extension part of the operation window of the mirror body is distributed on the mirror tail. The extension part of the operation window is in an inverted V shape, and the vertex of the V shape corresponds to the 1st, 3rd, 5th, 7th, 9th, and 11th points in the knee-chest position of the anal physical examination. There are four pairs of fixed windows on the mirror tail. The tail end of the inner core body part of the mirror body is closed to form a plane. The inner core body part of the mirror body extends around at the same plane as the mirror tail to form a baffle of the inner core of the mirror body. The total diameter of the baffle of the inner core of the mirror body plus the inner core of the mirror body matches the inner diameter of the butt joint part of the mirror tail.

The front end of the operation window is in an inclined shape with the inner side high and the outer side low from the inner wall to the outer wall of the mirror body to reduce the scratching of the operation window front end on the surgical wound surface during the postoperative withdrawal of the mirror.

[0011] Optionally, the length of the four pairs of fixed windows is 8 mm, the width is 3 mm, and the distance from the edge of the opening of the mirror tail is 6 mm. The opening distance of each pair is one-twelfth of the circumference of the mirror body. The midpoint of the opening distance corresponds to the 3rd, 6th, 9th, and 12th points in the knee-chest position of the anal physical examination, and the fixed windows are symmetrically arranged in pairs.

[0012] Optionally, the head of the inner core of the mirror body and the inner core body part of the mirror body are integrated and hollow, with a wall thickness of 1 - 2 mm. The length of the inner core body part of the mirror body is equal to the length of the mirror body plus the vertical length of the mirror tail plus the extended 20 mm. The tail end of the inner core body part of the mirror body is closed to form a plane, and the surface of this plane is textured to increase friction, which is beneficial for intraoperative operation.

[0026] In order to illustrate the technical solutions described in this application, the following will be described through specific embodiments.

[0027] Embodiment 1

[0028] An anoscope for positioning and quantitatively treating hemorrhoids includes a mirror body, a mirror tail, and a core inside the mirror body. In the description of the present utility model, it should be understood that the positional relationships indicated by terms such as "point", "front", and "rear" are based on the positional relationships shown in the drawings, corresponding to the 1 to 12 o'clock positions in the knee-chest position of an anal physical examination, and are only for the convenience of describing the positions of the respective openings of the present utility model.

[0029] As Figure 2 shown, the mirror body 13 and the mirror tail 14 are integrated. The mirror tail 14 expands in a flared shape along the rear end 19 of the mirror body, and the best expansion angle is 30 - 60 degrees, that is, the included angle between the mirror body and the mirror tail is 150 - 120 degrees, and the expanded extension length is 40 mm. The wall thickness of the mirror tail 14 is the same as that of the mirror body 13, which is 2 mm. The opening of the mirror tail 14 is circular, and the circular plane formed by the circular plane of the mirror tail 14 and the rear end 19 of the mirror body is parallel to each other, and the centers of the circles are on the same straight line, and its inner and outer surfaces are smooth. The mirror body 13 is cylindrical, 50 - 100 mm long, and the optimal value of the inner diameter of the mirror body 13 is 22 to 30 mm. The front end 20 of the mirror body has a round and smooth tube wall. Six openings are evenly distributed around the rear end 19 of the mirror body as operation windows 1, 3, 5, 7, 9, 11. The width of each operation window is one-twelfth of the circumference of the mirror body 13. The lengths of the operation windows 1, 5, 9 are 40 mm, and the lengths of the operation windows 3, 7, 11 are 30 mm. The extension parts of each operation window towards the mirror tail 14 are in an inverted V shape. The V shape is an isosceles triangle, and the vertex of the V shape and the center point of the operation window of the mirror body are in the same plane, that is, corresponding to the 1, 3, 5, 7, 9, 11 o'clock positions in the knee-chest position of an anal physical examination. The extension length of the V shape is 15 mm. The front end 17 of the operation window slopes from the inner wall to the outer wall of the mirror body in a shape with the inner side higher and the outer side lower to reduce the scratching of the surgical wound by the front end 17 of the operation window during the retraction of the mirror after the operation.

[0030] As Figure 2and Figure 3 As shown, four pairs of fixed windows 2, 6, 8, and 12 are located at the mirror tail 14. They are four pairs of small rectangular openings, 8 mm in length, 3 mm in width, 6 mm away from the opening edge of the mirror tail 14. The spacing between each pair of openings is one-twelfth of the circumference of the mirror body. The midpoints of the opening spacings correspond to the 3, 6, 9, and 12 o'clock positions in the knee-chest position of the anal physical examination. Fixed window 2 is symmetrical to fixed window 8, and fixed window 12 is symmetrical to 6.

[0031] As Figure 4 shown, the head 15 of the inner core of the mirror body and the body part 16 of the inner core of the mirror body are integrated into one, being hollow with a wall thickness of 1 - 2 mm. The length of the body part 16 of the inner core of the mirror body is equal to the length of the mirror body 13 plus the vertical length of the mirror tail 14 plus the extended 20 mm. The tail end 18 of the body part 16 of the inner core of the mirror body is closed to form a plane, and the surface of this plane is textured to increase friction, facilitating intraoperative operation; at the same plane as the fixed window, the body part 16 of the inner core of the mirror body horizontally extends to form the inner core baffle 10 of the mirror body. The total diameter of this baffle plus the inner core of the mirror body matches the inner diameter of the mirror tail 14 at this position. The thickness of this baffle is 2 mm, making the bottom edge of the head 15 of the inner core of the mirror body parallel to the front end 20 of the mirror body; the body part 16 of the inner core of the mirror body is cylindrical, and its diameter size matches the inner diameter of the mirror body 13. The head 15 of the inner core of the mirror body is in the shape of a blunt cone, with a cone height of 20 mm, a flat and blunt cone top, and the diameter of the bottom of the cone being the same as the diameter of the body part 16 of the inner core of the mirror body.

[0032] Example 2

[0033] As Figure 2 shown, the angle at which the mirror tail 14 expands in a flared shape along the rear end 19 of the mirror body can be other degrees, and the extended length can also be adjusted to adapt to the different depths of the gluteal sulcus of different patients. The wall thickness and inner diameter of the mirror body 13 can be adjusted according to the strength and toughness of the manufacturing material, ensuring that the operation window does not deform or collapse during the operation, and at the same time ensuring that the total circumference of the mirror body 13 is less than or equal to 110 mm.

[0034] Example 3

[0035] As Figure 3 shown, the four pairs of fixed windows 2, 6, 8, and 12 can also be located at other four symmetrical positions on the mirror tail 14, or the fixed windows can be in other shapes such as circular. The opening spacing of each pair of fixed windows can be other values, but it should be convenient for fixation during the operation.

[0036] Example 4

[0037] As Figure 4 shown, the head 15 of the inner core of the mirror body and the body part 16 of the inner core of the mirror body can also be designed to be solid, and the inner core baffle 10 of the mirror body can also be set to other sizes, as long as it is ensured that its size matches the inner diameter of the mirror tail 14, so that the body part 16 of the inner core of the mirror body does not exceed the front end 20 of the mirror body. The total length of the body part 16 of the inner core of the mirror body can be appropriately extended further, but it should be convenient for intraoperative operation and use.

[0038] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
