DETAILED DESCRIPTION

[0028] The embodiment of the present invention provides an expansion component of a visualization anorectal mirror, such as Figure 1-6 As shown, it includes two arc-shaped pieces 1, a base 2, a water pipe 3, an elastic hose 4 and a liquid tester 5. The two arc-shaped pieces 1 are arranged symmetrically on the left and right. The base 2 is located behind the arc-shaped piece 1. There is an extension section at the rear end of the arc-shaped piece 1. The arc-shaped piece 1 and the extension section are formed as one piece.

[0029] The extended section of the curved piece 1 slides with the base 2. A water pipe 3 and an elastic hose 4 are embedded in the surface of the curved piece 1. The front end of the curved piece 1 serves as an observation port, and a camera assembly, comprising a camera and a light, is fixedly mounted on the inner wall of the port. Since the camera and light are conventional, their specific structure and connection methods are not described in detail.

[0030] The elastic hose 4 is symmetrically arranged on the upper and lower sides of the water pipe 3 , and the elastic hose 4 is connected to the water pipe 3 . The rear end of the water pipe 3 extends to the rear of the arc-shaped piece 1 and is connected to the liquid tester 5 .

[0031] The water pipe 3 is always flush with the surface of the arc-shaped piece 1. The elastic hose 4 is flush with the surface of the arc-shaped piece 1 when it is in a wrinkled state. Liquid water is poured into the liquid tester 5. The liquid tester 5 sends the liquid water into the water pipe 3 and the elastic hose 4. The elastic hose 4 expands and squeezes the anal muscles to make a preliminary expansion attempt.

[0032] Working Principle: Initially, two curved pieces 1 are brought together to form a cylinder that is inserted into the anorectal cavity. The entire cylinder is only one finger wide, and liquid water is concentrated in the liquid tester 5. When expansion is required, liquid water is slowly injected into the water pipe 3. The liquid water enters the elastic hose 4, causing it to expand and squeeze the anorectal muscles. This initial expansion of the soft material allows the patient time to adapt. Once the patient has adapted, the liquid water is returned to the liquid tester 5, and the curved piece 1 is slowly moved. Each movement of the curved piece 1 expands the entire cylinder by one finger.

[0033] Since the elastic hose 4 is made of soft material, the elastic hose 4 contacts the muscles, which facilitates muscle adaptation and has a cushioning effect.

[0034] The liquid tester 5 is provided with a sensing component, which is used to detect the tension of the muscles.

[0035] The sensing assembly includes a rubber piston 6, a hollow ring 52, a slide rod 53, a small spring 54, and a pressure sensing unit 55. The rubber piston 6 slides inside the liquid tester 5. The ring 52 is fixedly mounted on the outside of the liquid tester 5. The slide rod 53 is located outside the ring 52. The small spring 54 is sleeved on the outside of the slide rod 53. The lower end of the slide rod 53 extends into the ring 52 and is fixedly mounted with a small magnet 56. The pressure sensing unit 55 is fixedly mounted inside the ring 52 and is aligned with the small magnet 56.

[0036] An annular recess 61 is formed on the side of the rubber piston 6 , and an iron sheet 62 is fixedly installed in the recess 61 . When the rubber piston 6 is aligned with the ring 52 , the iron sheet 62 is aligned with the pressure sensing unit 55 .

[0037] The slide bar 53 is slidably matched with the ring 52 , one end of the small spring 54 is welded to the outer side of the ring 52 , and the other end of the small spring 54 is welded to the upper end of the slide bar 53 .

[0038] The liquid tester 5 also includes a syringe, a push rod 51, and a steel wire 511. The front end of the syringe is connected to the rear end of the water pipe 3, the ring 52 is welded to the syringe body, the push rod 51 extends into the syringe from the rear, the push rod 51 and the syringe are slidably matched, and the steel wire 511 passes through the push rod 51 and is fixed to the rubber piston 6.

[0039] A display is fixedly mounted on the base 2, and the display is electrically connected to the pressure sensing unit 55, and the display shows the pressure detected by the pressure sensing unit 55. An air hole 56 is provided at the rear end of the syringe to facilitate the movement of the push rod 51.

[0040] Working principle: When liquid water needs to be injected into the water pipe 3, the push rod 51 is slowly pushed into the syringe. The push rod 51 pushes the rubber piston 6 to move, so that the rubber piston 6 is aligned with the ring 52, and liquid water is injected into the elastic hose 4. At this time, under the influence of magnetic force, the small magnet 56 approaches the rubber piston 6, and the slide rod 53 moves into the ring 52. At the same time, the pressure sensing unit 55 is squeezed.

[0041] After the liquid water is injected, push rod 51 is pulled outward. Rubber piston 6 remains within ring 52. Although the muscles still compress the elastic hose 4, the friction of rubber piston 6 is currently greater than the muscle pressure. Therefore, rubber piston 6 moves back a short distance, but overall, rubber piston 6 does not completely leave ring 52. Most of rubber piston 6 remains within ring 52, and small magnet 56 is still affected by the magnetic force.

[0042] When the anorectal area expands to a certain degree, the muscles reach their upper limit of compression and deformation. At this point, the stiffened muscles exert pressure on the elastic hose 4, and the backflow of liquid water pushes the rubber piston 6 a considerable distance, even out of the inner side of the ring 52. This weakens the pressure on the pressure sensing unit 55. When the value measured by the pressure sensing unit 55 falls within a preset range, expansion is no longer possible and the muscle compression has reached its upper limit. To reset the rubber piston 6, pull the steel wire 511 outward.

[0043] The cross-section of the base 2 is concave, and multiple pillars 21 are symmetrically welded on the left and right sides of the inner wall of the base 2. The multiple pillars 21 are grouped in pairs. A large spring 22 is provided between the two pillars 21 in the same group. The pillars 21 slide in conjunction with the extension section of the arc-shaped piece 1. One end of the large spring 22 is welded to the inner wall of the base 2, and the other end of the base 2 is welded to the extension section.

[0044] The support 21 is arranged horizontally, and has insertion holes 211 spaced evenly along the support 21. The insertion rods 23 extend through these holes. During operation, the extension is gently pressed to insert the insertion rods 23 into the outer holes 211, achieving gradual expansion. The insertion rods 23 cooperate with the holes 211 to gradually move the curved pieces 1 away from each other.

[0045] To sum up, the expansion component of the visualization anorectal scope consists of two arc-shaped pieces 1, a base 2, a water pipe 3, an elastic hose 4, a liquid tester 5 and a rubber piston 6. The arc-shaped piece 1 slides with the base 2, and by injecting liquid water into the elastic hose 4, it serves as a preliminary attempt to allow the patient to adapt in advance. The liquid tester 5 is provided with a ring 52, a slide rod 53, a small spring 54, a pressure sensing unit 55, and a small magnet 56, and cooperates with the rubber piston 6 to detect the degree of tension of the anorectal muscles, thereby avoiding inadequate or excessive expansion of the patient's anorectal canal, and preventing excessive expansion from causing tearing injuries to the patient.

[0046] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
