Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and particularly to a rotary scaling retractor. Background Art
[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used on the human body, including the required computer software. Medical devices are an essential and integral part of the healthcare field and, together with drugs, medical treatment technologies, etc., are among the three major pillars of healthcare.
[0003] After the use of an anal dilator, a relatively common problem is that once the dilation operation is completed, the tool often has difficulty maintaining its preset position and is prone to unnecessary movement due to external interference or the patient's own activities. This positional instability will directly affect the sustainability and reliability of the dilation effect, possibly resulting in the treatment outcome not being as desired. Worse still, if the tool's position shifts, it may pose additional risks to the patient. In addition, considering the significant differences in the anatomical structures and treatment needs of different patients, the requirements for the dilation range also vary. However, after the dilation tool completes the dilation, its size is usually fixed and cannot be flexibly adjusted to meet the personalized needs of different patients. This limitation greatly restricts the wide applicability and effectiveness of these tools in clinical practice. Summary of the Invention
[0004] The purpose of the present invention is to provide a rotary scaling retractor, which has the advantages of good fixing effect and adjustable dilation range, and solves the problems raised in the above background art.
[0005] To achieve the above object, the present invention provides the following technical solution: A rotary scaling retractor, including a first annular block, a sleeve block is provided at the bottom of the first annular block, a toothed ring is fixedly connected to the inner wall of the sleeve block, a first handle is fixedly connected to the surface of the sleeve block, a second annular block is provided at the bottom of the sleeve block, a fixing block is provided at the bottom of the second annular block, a second handle is fixedly connected to the surface of the fixing block, a through groove is opened in the fixing block, a first toothed plate is slidably connected to the inner cavity of the through groove, a moving block is fixedly connected to one side of the first toothed plate, a groove is opened on one side of the inner cavity of the through groove, a gear is rotatably connected to the inner cavity of the groove, the first toothed plate meshes with the gear, a second toothed plate is embedded on the surface of the first annular block, a square plate is fixedly connected to the top of the first handle, a cavity is opened at the top of the first handle, and a locking mechanism is provided in the inner cavity of the cavity.
[0006] Further, as a preferred embodiment of the present invention, the locking mechanism includes a movable block slidably connected to the inner cavity of the cavity. One side of the movable block is fixedly connected to a spring, and one end of the spring is fixedly connected to the first handle. The top of the movable block is fixedly connected to a connecting block. A push plate is arranged on the top of the square plate, and the bottom of the push plate is fixedly connected to the connecting block. One side of the push plate is fixedly connected to a triangular block.
[0007] Further, as a preferred embodiment of the present invention, sliding grooves are formed on both sides of the inner cavity of the cavity, and sliders are slidably connected to the inner cavities of the sliding grooves. One side of the slider is fixedly connected to the movable block.
[0008] Further, as a preferred embodiment of the present invention, a telescopic structure is formed between the movable block and the spring, and the maximum moving distance of the movable block is equal to the deformation amount of the spring.
[0009] Further, as a preferred embodiment of the present invention, anti-slip blocks are fixedly connected to the top of the push plate, and the number of anti-slip blocks is eight.
[0010] Further, as a preferred embodiment of the present invention, an arc surface is arranged on one side of the moving block, and the surface of the arc surface is smooth.
[0011] Further, as a preferred embodiment of the present invention, a plurality of bolts distributed annularly are arranged on the top of the first annular block, and the bottom ends of the bolts penetrate to the bottom of the fixed block.
[0012] The usage method of the rotary zooming hook includes the following steps:
[0013] Step 1: The user holds the first handle and the second handle with both hands and inserts the moving block into the patient's anus. Then, place the fingers on the surface of the push plate. By moving the push plate, the push plate drives the connecting block to move, and the connecting block drives the movable block to slide in the inner cavity of the cavity. When the movable block moves, it will drive the slider to slide in the inner cavity of the sliding groove, and at the same time compress the spring. When the push plate moves, the locking between the triangular block and the second toothed plate can be released.
[0014] Step 2: The user moves both hands to both sides, so that the second handle drives the fixed block to rotate, and the first handle drives the sleeve block to rotate. When the sleeve block rotates, it will drive the toothed ring to rotate. When the toothed ring rotates, it will drive the gear to rotate. When the gear rotates, it will drive one side of the first toothed plate to move outward, and the other side of the first toothed plate drives the moving block to move, thereby expanding the patient's anus.
[0015] Beneficial effects: The technical solution of this application has the following technical effects: The present invention has the advantages of good fixing effect and adjustable expansion range. During actual use, through the setting of the locking structure, when the push plate is not pushed, the spring remains in its original state, enabling the triangular block to firmly engage into the gap of the second toothed plate, preventing the sleeve block from rotating randomly. Through the meshing setting of the gear and the first toothed plate, when the sleeve block rotates, the toothed ring can drive the gear to rotate, thereby pushing the first toothed plate to move outward. The first toothed plate drives the moving block to move, so that the expansion range can be adjusted according to needs, meeting the anal dilation requirements of different patients.

A moving block 10 is fixedly connected to one side of the first toothed plate 9. A groove 11 is opened on one side of the inner cavity of the through groove 8. A gear 12 is rotatably connected to the inner cavity of the groove 11. The first toothed plate 9 is engaged with the gear 12. A second toothed plate 13 is embedded on the surface of the first annular block 1. A square plate 14 is fixedly connected to the top of the first handle 4. A cavity 15 is opened at the top of the first handle 4. A locking mechanism 16 is arranged in the inner cavity of the cavity 15.
[0026] Specifically, the locking mechanism 16 includes a movable block 161 slidably connected to the inner cavity of the cavity 15. A spring 162 is fixedly connected to one side of the movable block 161. One end of the spring 162 is fixedly connected to the first handle 4. A connecting block 163 is fixedly connected to the top of the movable block 161. A push plate 164 is arranged at the top of the square plate 14. The bottom of the push plate 164 is fixedly connected to the connecting block 163. A triangular block 165 is fixedly connected to one side of the push plate 164.
[0027] In this embodiment: Through the setting of the locking mechanism 16, the sleeve block 2 is fixed, preventing the sleeve block 2 from rotating during placement and making it difficult for the expansion angle to change.
[0028] Specifically, sliding grooves 17 are opened on both sides of the inner cavity of the cavity 15. A slider 18 is slidably connected to the inner cavity of the sliding groove 17. One side of the slider 18 is fixedly connected to the movable block 161.
[0029] In this embodiment: Through the cooperation of the sliding groove 17 and the slider 18, the movable block 161 is limited, improving the stability of the movable block 161 during movement.
[0030] Specifically, a telescopic structure is formed between the movable block 161 and the spring 162, and the maximum moving distance of the movable block 161 is equal to the deformation amount of the spring 162.
[0031] In this embodiment: through the arrangement of the spring 162, the triangular block 165 can be firmly placed on the surface of the second toothed plate 13, so that the sleeve block 2 is not easily rotated.
[0032] Specifically, anti-slip blocks are fixedly connected to the top of the push plate 164, and the number of anti-slip blocks is eight.
[0033] In this embodiment: through the arrangement of the anti-slip blocks, the friction between the user's palm and the push plate 164 is increased, so as to facilitate the movement of the push plate 164.
[0034] Specifically, an arc surface is arranged on one side of the moving block 10, and the surface of the arc surface is smooth.
[0035] Specifically, a plurality of bolts 19 distributed annularly are arranged on the top of the first annular block 1, and the bottom ends of the bolts 19 penetrate through to the bottom of the fixed block 6.
[0036] In this embodiment: through the arrangement of the bolts 19, the first annular block 1, the sleeve block 2 and the fixed block 6 are connected, which is convenient for the user to assemble them.
[0037] The using method of the rotary zoom hook includes the following steps:
[0038] Step 1: The user holds the first handle 4 and the second handle 7 with both hands and puts the moving block 10 into the patient's anus. Then, the fingers are placed on the surface of the push plate 164. By moving the push plate 164, the push plate 164 drives the connecting block 163 to move, and the connecting block 163 drives the movable block 161 to slide in the inner cavity of the cavity 15. When the movable block 161 moves, it will drive the slider 18 to slide in the inner cavity of the chute 17, and at the same time, the spring 162 is compressed. When the push plate 164 moves, the locking between the triangular block 165 and the second toothed plate 13 can be released.
[0039] Step 2: The user moves both hands to both sides, so that the second handle 7 drives the fixed block 6 to rotate, and the first handle 4 drives the sleeve block 2 to rotate. When the sleeve block 2 rotates, it will drive the toothed ring 3 to rotate. When the toothed ring 3 rotates, it will drive the gear 12 to rotate. When the gear 12 rotates, it will drive one side of the first toothed plate 9 to move outward, and the other side of the first toothed plate 9 drives the moving block 10 to move, so as to expand the patient's anus.
