[0023] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0024] Example

[0025] The anorectal retractor described in this embodiment is as follows: Figure 1 and Figure 2 As shown, it includes a first expansion plate 1, a second expansion plate 2 is arranged on the right side of the first expansion plate 1, a connecting plate 3 is fixed to the outer side wall of the second expansion plate 2, a finger buckle plate 6 is fixed to the other end of the connecting plate 3, a sliding sleeve 4 that can slide left and right is mounted on the connecting plate 3, a connecting rod 11 is connected between the sliding sleeve 4 and the first expansion plate 1, a through groove that communicates left and right is opened on the finger buckle plate 6, a buckle ring 9 that can swing left and right is hinged in the through groove, a push rod 10 is independently installed in the buckle ring 9, and one end of the push rod 10 passes through the buckle ring 9 and is connected to the sliding sleeve 4; a plurality of card slots distributed from left to right are opened on the side wall of the push rod 10, and a card block that can be inserted into any card slot and limit the push rod 10 from moving to the right is fixed on the inner ring of the buckle ring 9;

[0026] like Figure 1 and Figure 2 As shown, the first expansion plate 1 and the second expansion plate 2 are both conventional components on the existing retractor; the cross-sections of the connecting plate 3 and the sliding sleeve 4 are both rectangular structures, so that the sliding sleeve 4 has better stability during the left and right sliding process; the middle part of the finger clip plate 6 is fixed to the right end of the connecting plate 3 and is vertically arranged therewith, the upper half of the finger clip plate 6 is located above the connecting plate 3, and the lower half thereof is located below the connecting plate 3. When in use, the middle finger and index finger of the medical staff respectively hold the upper half and the lower half of the finger clip plate 6, and the palm pushes the push rod 10 to slide to the left; the connecting rod 11 is an arc-shaped structure, one end of the connecting rod 11 is fixed to the outer wall of the first expansion plate 1, and the other end thereof is fixed to the rear wall of the sliding sleeve 4, and the arc-shaped connecting rod 11 avoids the first expansion plate 1 and the second expansion plate 2 directly above, so as to avoid the medical staff from blocking their sight during the surgical treatment; a rib is fixed at the connection between the sliding sleeve 4 and the connecting rod 11, and the rib is fixed between the two to make the fixing of the connecting rod 11 more stable;

[0027] The through slot is located in the lower half of the finger plate 6, the push rod 10 is located below the connecting plate 3, and the left end of the push rod 10 is fixed to the bottom of the sliding sleeve 4; during the production process, the left end of the push rod 10 needs to be bent and fixed to the bottom of the sliding sleeve 4, or a connecting block is fixed between the left end of the push rod 10 and the bottom of the connecting plate 3 to connect the two; the buckle 9 is a rectangular structure, and the front and rear side walls of the buckle 9 are hinged to the front and rear groove walls of the through slot through a hinge column, and the buckle 9 is tilted with the left side higher and the right side lower; when the buckle 9 is in a tilted state with the left side higher and the right side lower, the push rod 10 passes through the inside of the buckle 9, The buckle 9 is a rectangular structure, the card block is located at the inner bottom of the buckle 9, and all the card slots are evenly spaced and distributed at the lowest point of the outer wall of the push rod 10; when in use, when the right swing end of the buckle 9 swings upward, the card block is inserted into the card slot to prevent the push rod 10 from sliding to the right, but the card block cannot prevent the push rod 10 from sliding to the left. The specific structure of the card slot is shown in 1, the left slot wall is in a vertical state, and the right side is in an arc-shaped opening shape, the card block can slide from the right side of the card slot, and the side of the card block inserted into the card slot is a right-angle structure, which can better insert into the card slot to prevent the push rod 10 from sliding to the right;

[0028] The pushing end of the push rod 10 is fixed with a push plate 8, which increases the contact area when used by medical staff and is more convenient for operation; during operation, the index finger and middle finger of the medical staff respectively hold the upper and lower halves of the finger holding plate 6 (that is, the part below the through groove), and the palm or thumb presses the push plate 8 to make the push rod 10 slide to the left, and the block does not prevent the push rod 10 from moving to the left. The push rod 10 drives the sliding sleeve 4 to slide to the left, and the sliding sleeve 4 is connected by the connecting rod 11, thereby driving the first expansion plate 1 to expand, so as to complete the expansion of the anorectal, and then the push rod 10 can be directly released, and the push rod 10 is locked by the block to prevent it from sliding to the right, so that the first expansion plate 1 keeps expanding the anorectal, so as to facilitate the operation of medical staff;

[0029] like Figure 1 As shown, a first magnet 5 is fixed to the bottom of the connecting plate 3, and a mounting plate 7 is fixed to the left swinging end of the buckle 9, and a second magnet that repel each other with the first magnet 5 is fixed on the mounting plate 7; this section as a whole constitutes a thrust component for pushing the buckle 9 to swing and causing the card block to be stuck in the card slot. When in use, the mutually repelling sides of the first magnet 5 and the second magnet are opposite to each other, and the repulsive force generated between the two is used to push the left swinging end of the buckle 9 to swing downward and the right swinging end to swing upward, and the card block is automatically stuck in it when it is opposite to the card slot; in addition, the thrust component can also be a spring, one end of the spring is fixed to the bottom of the connecting plate 3, and the other end thereof is against the top of the mounting plate 7; when in use, the right swinging end of the buckle 9 is swung upward by the thrust of the spring; or an arc spring is installed between the right side wall of the finger buckle plate 6 and the right swinging end of the buckle 9, one end of the arc spring is fixed to the right side wall of the finger buckle plate 6, and the other end thereof is fixed to the right swinging end of the buckle 9, and the right swinging end of the buckle 9 is pushed to swing upward by the arc spring;

[0030] During actual use, the medical staff pushes the push rod 10 to move to the left to make the first expansion plate 1 open the anorectum, and then releases the push rod 10. The card block is inserted into the card slot to prevent the push rod 10 from sliding to the right, so that the first expansion plate 1 can maintain the expansion of the patient's anorectum, which is convenient for medical staff to perform surgical treatment. When the first expansion plate 1 and the second expansion plate 2 are to be brought close together, it is only necessary to press the right swing end of the buckle 9 to swing downward to disengage the card block from the card slot.
