Description

Technical Field

[0001] The invention belongs to the technical field of anal retraction, and in particular relates to an automatic anal retractor and method. Background Art

[0002] An automatic anal retractor is a medical device used to keep the anus open during anal examination or surgery to allow doctors to better observe and operate.

[0003] The existing automatic anal retractor has the following disadvantages in actual use: 1. It cannot ensure that the six groups of opening plates can slide outward synchronously when the anus is retracted. In actual use, medical staff cannot use it alone;

[0004] 2. The anus may be subjected to excessive force when being retracted, which may cause tearing of the anus, further increasing the probability of injury to the patient;

[0005] 3. The automatic anal retractor cannot be bound to the patient's body when in use, so the retractor may shake left and right during actual use, causing discomfort in the patient's anus;

[0006] 4. When the device is idle, the structure for retracting the anus occupies a relatively large space and is inconvenient to disassemble, which makes the overall production value of the device low. Summary of the invention

[0007] To solve the problems raised in the above background technology, the present invention provides an automatic anal retractor, which is convenient for simultaneously opening six groups of opening plates to slide outward, convenient for fine-tuning the positions of the opening plates, convenient for binding the retractor to the patient's body, and convenient for disassembling and storing the retractor.

[0008] The invention provides a method for using an automatic anal retractor.

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic anal retractor and method, comprising a circular ring, wherein an expansion plate synchronous external support mechanism is arranged through the interior of the circular ring, a retractor disassembly and assembly mechanism is arranged at the connection of the expansion plate synchronous external support mechanism, a fixing ring is arranged at the upper end of the expansion plate synchronous external support mechanism, an expansion plate position fine-tuning mechanism is arranged inside the other end of the expansion plate synchronous external support mechanism near the center position of the circular ring, an expansion plate body is arranged at the other end of the expansion plate position fine-tuning mechanism, the side of the expansion plate body is arranged as a chamfered structure, and a retractor binding mechanism is arranged at the lower end of the circular ring.

[0013] Furthermore, the adjustment assembly includes bevel gear 1, a connecting bearing, a turning handle, a rotating rod and bevel gear 2. Bevel gear 1 is provided on the surface of one end of the threaded rod, bevel gear 2 is meshingly installed on the side of bevel gear 1, a rotating rod is provided on the side of bevel gear 2, a turning handle is provided on the other end of the rotating rod, and the connection between the rotating rod and the sliding rod is rotatably connected through a connecting bearing.

[0014] Furthermore, the retractor binding mechanism includes a fastening box, a control component, a motor, a rotating seat, a strap and a winding roller. A rotating seat is provided on the side of the ring, and a strap is rotatably connected to the side of the rotating seat. A fastening box is provided at the other end of the strap, and a motor is provided on the side of the fastening box. The output end of the motor is located inside the fastening box and a winding roller is provided. The other end of the strap is fixed to the surface of the winding roller, and a control component is provided on the other side of the fastening box.

[0015] Furthermore, the control component includes a controller and a pressure sensor. The controller is arranged on the side of the fastening box near the motor, and the pressure sensor is arranged on the other side of the fastening box near the patient's belly.

[0016] Furthermore, the retractor disassembly and assembly mechanism includes a socket, a fixing seat, an insertion rod, a fixing hole and a fixing component. The other end of the sliding rod is provided with a fixing seat, a side of the fixing seat is provided with a socket, and a fixing component is provided inside the side of the fixing seat. One end of the tripod is provided with an insertion rod, and a fixing hole is provided on the side of the insertion rod.

[0017] Furthermore, the fixing assembly includes a fixing rod, a limiting plate 2, a compression spring, a pull rod and a handle. A limiting plate 2 is arranged inside the side of the fixing seat, a fixing rod is fixedly arranged at one end of the limiting plate 2, a pull rod is fixedly arranged at the other end of the limiting plate 2, and a pull handle is arranged at the other end of the pull rod. A limiting groove corresponding to the limiting plate 2 is opened inside the fixing seat, and a compression spring is sleeved on the surface of the pull rod located inside the limiting groove.

[0018] Furthermore, a method for using an automatic anal retractor comprises the following steps:

[0019] S1: When using the retractor, first put the bandage on the patient's waist so that the ring is attached to the patient's buttocks. The control component controls the motor to start, and the motor starts to drive the roller to rotate. The rotation of the roller drives the bandage to roll on the surface of the roller, thereby tightening the bandage to prevent the ring from shaking left and right on the patient's buttocks when the retractor is in use, thereby causing secondary damage to the patient's anus. When the bandage is too tight, the pressure sensor will be subjected to the pressure of the patient's belly. The pressure sensor will convert the monitored pressure signal into an electrical signal and transmit it to the controller. The controller controls the motor to turn off, thereby automatically tightening the bandage.

[0020] S2: When the retractor is used, the expansion plate body located at the center of the circular ring is inserted into the patient's anus, and then the pull ring is pulled to drive the fixed ring to slide upward. Since the expansion plate body is arranged in an inclined shape, the lower end of the expansion plate body will clamp the skin inside the anus, and the upward movement of the fixed ring will drive the oblique connecting rod to slide upward. Due to the structural setting of the oblique connecting rod, the center of gravity is toward the outside of the circular ring. At this time, the oblique connecting rod will drive the sliding rod to slide outward, and the sliding of the sliding rod outward will drive the expansion plate body to expand the anus. When the fixed ring moves upward, it will drive the oblique connecting rod to move upward. At this time, the fixed ring will drive the buffer spring to stretch, and the stretching of the buffer spring will drive the inner rod to slide inside the outer rod, so that the rising height of each group of oblique connecting rods can be adjusted accordingly, thereby avoiding the problem of the sliding rod being stuck when sliding;

[0021] S3: After the expansion plate and the external expansion mechanism expand the anus synchronously, in order to prevent the anus from being expanded too much, the pulling force on the pull ring is appropriately reduced at this time, by turning the turning handle, the turning handle drives the rotating rod to rotate, the rotating rod drives the bevel gear 2 to rotate, the bevel gear 2 drives the bevel gear 1 to rotate, the bevel gear 1 drives the threaded rod to rotate, and the threaded rod drives the telescopic rod to rotate. Since the slider on the side of the telescopic rod is stuck in the slide groove on the inner wall of the slide rod, the threaded rod can drive the telescopic rod to slide outward at this time, thereby fine-tuning the tension of the anus to avoid damage to the anus;

[0022] S4: In order to facilitate the disassembly and storage of the retractor, by pulling the handle, the handle pulls the pull rod, and the pull rod pulls the limit plate 2 and the fixed rod. At the same time, the limit plate 2 will drive the compression spring to compress. At this time, the plug rod on the side of the tripod can be pulled out from the socket inside the fixed seat, thereby completing the disassembly of the retractor so that it can be stored separately, avoiding the retractor being too large and occupying a large space when stored. When the retractor needs to be assembled, the plug rod is inserted into the socket again. At this time, the handle is released, and the compression spring rebounds, thereby driving the fixed rod to be inserted into the inside of the fixed hole, thereby completing the assembly of the retractor.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention is provided with a synchronous external expansion mechanism of the expansion plates. The arrangement of the mechanism can conveniently drive the six groups of expansion plates to slide synchronously outward by pulling the pull ring, thereby expanding the patient's anus. The arrangement of the structure can make the retractor easy to use, and only one medical staff can use it freely.

[0025] 2. The present invention is provided with a fine-adjustment mechanism for the position of the expansion plate. The arrangement of this mechanism can avoid the problem of tearing of the patient's anus due to excessive force after the retractor has expanded the patient's anus. After the retractor has partially expanded the patient's anus, the expansion plate can be fine-adjusted through this structure to avoid secondary damage to the patient's anus.

[0026] 3. The present invention provides a retractor binding mechanism, which can bind the retractor to the patient's waist, so that the retractor can play a stabilizing role when in use, reducing the problem of the retractor shaking left and right when in use, thereby causing discomfort to the patient's anus.

[0027] 4. The present invention provides a retractor disassembly and assembly mechanism, which can facilitate the disassembly of the retractor so as to store the retractor, thereby preventing the external structure of the retractor from being too large, resulting in the retractor occupying a large space when stored.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1

[0040] See also Figure 1-9The present invention provides the following technical solutions: an automatic anal retractor and method, comprising a circular ring 1, a spreading plate synchronous external support mechanism 3 is arranged through the interior of the circular ring 1, a retractor disassembly and assembly mechanism 2 is arranged at the connection of the spreading plate synchronous external support mechanism 3, a fixing ring 4 is arranged at the upper end of the spreading plate synchronous external support mechanism 3, a spreading plate position fine-tuning mechanism 7 is arranged inside the other end of the spreading plate synchronous external support mechanism 3 near the center position of the circular ring 1, a spreading plate body 5 is arranged at the other end of the spreading plate position fine-tuning mechanism 7, the side of the spreading plate body 5 is arranged in a chamfered structure, and a retractor binding mechanism 6 is arranged at the lower end of the circular ring 1.

[0041] The present invention further provides that the synchronous external support mechanism 3 for the opening plate includes a pull ring 31, a tripod 32, an oblique connecting rod 33, a buffer assembly 34, a telescopic spring 35, a limit plate 36 and a slide rod 37. The interior of the circular ring 1 is provided with a slide rod 37, one end surface of the slide rod 37 is provided with a limit plate 36, the surface of the slide rod 37 is located on one side of the limit plate 36 and is sleeved with a telescopic spring 35, one end of the telescopic spring 35 is fixedly connected to the outer wall of the circular ring 1, the other end of the telescopic spring 35 is fixedly connected to the side of the limit plate 36, the other end of the slide rod 37 is provided with a tripod 32, the upper end of the tripod 32 is provided with an oblique connecting rod 33, the upper end of the oblique connecting rod 33 is provided with a buffer assembly 34, the upper end of the buffer assembly 34 is fixedly connected to the fixing ring 4,

[0042] By adopting the above technical solution, when the retractor is used, the expansion plate body 5 located at the center of the ring 1 is inserted into the patient's anus, and then the pull ring 31 is pulled, and the pull ring 31 drives the fixed ring 4 to slide upward. Since the expansion plate body 5 is arranged in an inclined state, the lower end of the expansion plate body 5 will clamp the skin inside the anus, and the upward movement of the fixed ring 4 will drive the oblique connecting rod 33 to slide upward. Due to the structural setting of the oblique connecting rod 33, the center of gravity is toward the outside of the ring 1. At this time, the oblique connecting rod 33 will drive the sliding rod 37 to slide outward, and the sliding of the sliding rod 37 to the outside will drive the expansion plate body 5 to expand the anus.

[0043] The present invention further comprises an inner rod 341, a buffer spring 342 and an outer rod 343. The upper end of the oblique connecting rod 33 is provided with the outer rod 343. The upper end of the outer rod 343 is slidably connected with the inner rod 341. The surfaces of the outer rod 343 and the inner rod 341 are sleeved with the buffer spring 342.

[0044] By adopting the above technical solution, when the fixing ring 4 moves upward, it will drive the oblique connecting rod 33 to move upward. At this time, the fixing ring 4 will drive the buffer spring 342 to stretch. The stretching of the buffer spring 342 will drive the inner rod 341 to slide inside the outer rod 343, so that the rising height of each group of oblique connecting rods 33 can be adjusted accordingly, thereby avoiding the problem of the sliding rod 37 getting stuck when sliding.

[0045] When the present embodiment is in use, when the retractor is used, the expansion plate body 5 located at the center of the circular ring 1 is inserted into the patient's anus, and then the pull ring 31 is pulled, and the pull ring 31 drives the fixing ring 4 to slide upward. Since the expansion plate body 5 is arranged in an inclined shape, the lower end of the expansion plate body 5 will clamp the skin inside the anus, and the upward movement of the fixing ring 4 will drive the oblique connecting rod 33 to slide upward. Due to the structural setting of the oblique connecting rod 33, the center of gravity is toward the outside of the circular ring 1. At this time, the oblique connecting rod 33 will drive the sliding rod 37 to slide outward, and the sliding of the sliding rod 37 outward will drive the expansion plate body 5 to expand the anus. When the fixing ring 4 moves upward, although it will drive the oblique connecting rod 33 to move upward, at this time, the fixing ring 4 will drive the buffer spring 342 to stretch, and the stretching of the buffer spring 342 will drive the inner rod 341 to slide inside the outer rod 343, so that the rising height of each group of oblique connecting rods 33 can be adjusted accordingly, thereby avoiding the problem of the sliding rod 37 being stuck when sliding.

[0046] Example 2

[0047] The present embodiment is different from the embodiment 1 in that the opening plate position fine-tuning mechanism 7 comprises an adjusting assembly 71, a threaded rod 72, a slider 73, a telescopic rod 74 and a slide groove 75. The internal rotation connection of the slide rod 37 is provided with a threaded rod 72, one end surface of the threaded rod 72 is provided with an adjusting assembly 71, the other end surface of the threaded rod 72 is threadedly connected with a telescopic rod 74, the other end of the telescopic rod 74 is fixedly connected to the opening plate body 5, a slider 73 is provided on the side of one end of the telescopic rod 74, and a slide groove 75 corresponding to the slider 73 is provided on the inner wall of the slide rod 37.

[0048] By adopting the above technical solution, when the expansion plate and the synchronous external expansion mechanism 3 expand the anus, in order to prevent the anus from being expanded too much, the pulling force on the pull ring 31 is appropriately reduced at this time, and the threaded rod 72 is driven to rotate by the adjustment component 71, and the rotation of the threaded rod 72 drives the telescopic rod 74 to rotate. Since the slider 73 on the side of the telescopic rod 74 is stuck in the slide groove 75 on the inner wall of the slide rod 37, the rotation of the threaded rod 72 can drive the telescopic rod 74 to slide outward, thereby fine-tuning the tension of the anus to avoid damage to the anus.

[0049] The present invention further comprises a bevel gear 1 711, a connecting bearing 712, a turning handle 713, a rotating rod 714 and a bevel gear 2 715. The surface of one end of the threaded rod 72 is provided with a bevel gear 1 711, a bevel gear 2 715 is meshedly mounted on the side of the bevel gear 1 711, a rotating rod 714 is provided on the side of the bevel gear 2 715, a turning handle 713 is provided on the other end of the rotating rod 714, and the connecting portion of the rotating rod 714 and the sliding rod 37 is rotatably connected via the connecting bearing 712.

[0050] By adopting the above technical solution, the handle 713 is rotated, and the rotation of the handle 713 drives the rotating rod 714 to rotate, and the rotation of the rotating rod 714 drives the bevel gear 2 715 to rotate, and the rotation of the bevel gear 2 715 drives the bevel gear 1 711 to rotate, and the rotation of the bevel gear 1 711 drives the threaded rod 72 to rotate.

[0051] When the present embodiment is in use, after the expansion plate synchronizes with the external expansion mechanism 3 to expand the anus, in order to prevent the anus from being expanded too much, the pulling force on the pull ring 31 is appropriately reduced by rotating the turning handle 713. The turning handle 713 drives the rotating rod 714 to rotate, and the rotating rod 714 drives the bevel gear 2 715 to rotate. The bevel gear 2 715 drives the bevel gear 1 711 to rotate. The bevel gear 1 711 drives the threaded rod 72 to rotate. The threaded rod 72 drives the telescopic rod 74 to rotate. Since the slider 73 on the side of the telescopic rod 74 is stuck in the slide groove 75 on the inner wall of the slide rod 37, the threaded rod 72 can drive the telescopic rod 74 to slide outward by rotation, thereby fine-tuning the tension of the anus to avoid damage to the anus.

[0052] Example 3

[0053] The present embodiment is different from the embodiments 1 and 2 in that the retractor binding mechanism 6 includes a fastening box 61, a control assembly 62, a motor 63, a rotating seat 64, a binding belt 65 and a winding roller 66.

The other side of the fastening box 61 is provided with a control assembly 62.

[0054] By adopting the above technical solution, when the retractor is used, the strap 65 is first put on the patient's waist so that the ring 1 is attached to the patient's buttocks, and the control component 62 controls the motor 63 to start. The motor 63 starts to drive the roller 66 to rotate, and the rotation of the roller 66 drives the strap 65 to roll on the surface of the roller 66, thereby tightening the strap 65 and preventing the ring 1 from shaking left and right on the patient's buttocks when the retractor is in use, thereby causing secondary damage to the patient's anus.

[0055] In the present invention, the control component 62 includes a controller 621 and a pressure sensor 622. The controller 621 is disposed on the side of the fastening box 61 near the motor 63, and the pressure sensor 622 is disposed on the other side of the fastening box 61 near the patient's belly.

[0056] By adopting the above technical solution, when the strap 65 is too tight, the pressure sensor 622 will be subjected to the pressure of the patient's belly. The pressure sensor 622 will convert the monitored pressure signal into an electrical signal and transmit it to the controller 621. The controller 621 controls the motor 63 to turn off, thereby realizing the automatic tightening of the strap 65.

[0057] When the present embodiment is in use, when the retractor is used, firstly, the strap 65 is put on the patient's waist position so that the ring 1 is attached to the patient's buttocks, and the control component 62 controls the motor 63 to start, and the motor 63 starts to drive the roller 66 to rotate, and the rotation of the roller 66 drives the strap 65 to roll on the surface of the roller 66, thereby realizing the tightening of the strap 65, and preventing the ring 1 from swinging left and right on the patient's buttocks when the retractor is in use, thereby causing secondary damage to the patient's anus. When the strap 65 is too tight, the pressure sensor 622 will be subjected to the pressure of the patient's belly, and the pressure sensor 622 will convert the monitored pressure signal into an electrical signal and transmit it to the controller 621, and the controller 621 controls the motor 63 to turn off, thereby realizing the automatic tightening of the strap 65.

[0058] Example 4

[0059] The present embodiment is different from the above embodiment in that: the retractor disassembly and assembly mechanism 2 comprises a plug hole 21, a fixing seat 22, an insertion rod 23, a fixing hole 24 and a fixing assembly 25; the other end of the slide bar 37 is provided with a fixing seat 22, the side of the fixing seat 22 is provided with a plug hole 21, the side of the fixing seat 22 is provided with a fixing assembly 25; one end of the tripod 32 is provided with an insertion rod 23, the side of the insertion rod 23 is provided with a fixing hole 24,

[0060] By adopting the above technical solution, in order to facilitate the disassembly and storage of the retractor, the fixing ring 4 together with the tripod 32 can be removed by releasing the limit of the fixing assembly 25 on the insertion rod 23 so that they can be stored separately, avoiding the retractor being too large and occupying a large space when stored.

[0061] The present invention further comprises a fixing assembly 25 including a fixing rod 251, a limiting plate 252, a compression spring 253, a pull rod 254 and a handle 255. A limiting plate 252 is provided inside the side of the fixing seat 22. A fixing rod 251 is fixedly provided at one end of the limiting plate 252. A pull rod 254 is fixedly provided at the other end of the limiting plate 252. A pull handle 255 is provided at the other end of the pull rod 254. A limiting groove corresponding to the limiting plate 252 is provided inside the fixing seat 22. A compression spring 253 is sleeved on the surface of the pull rod 254 located inside the limiting groove.

[0062] By adopting the above technical solution, by pulling the handle 255, the handle 255 pulls the pull rod 254, and the pull rod 254 pulls the limit plate 252 and the fixed rod 251. At the same time, the limit plate 252 will drive the compression spring 253 to compress. At this time, the insertion rod 23 on the side of the tripod 32 can be pulled out from the socket 21 inside the fixed seat 22, thereby completing the disassembly of the retractor so that it can be stored separately to avoid the retractor being too large and occupying a large space when stored. When the retractor needs to be assembled, the insertion rod 23 is inserted into the inside of the socket 21 again. At this time, the handle 255 is released, and the compression spring 253 rebounds, thereby driving the fixed rod 251 to be inserted into the inside of the fixed hole 24, thereby completing the assembly of the retractor.

[0063] When the present embodiment is in use, in order to facilitate the disassembly and storage of the retractor, by pulling the handle 255, the handle 255 pulls the pull rod 254, and the pull rod 254 pulls the limit plate 252 and the fixing rod 251. At the same time, the limit plate 252 will drive the compression spring 253 to be compressed. At this time, the insertion rod 23 on the side of the tripod 32 can be pulled out from the socket 21 inside the fixing seat 22, thereby completing the disassembly of the retractor so that it can be stored separately to avoid the retractor being too large and occupying a large space when stored. When the retractor needs to be assembled, the insertion rod 23 is inserted into the inside of the socket 21 again. At this time, the handle 255 is released, and the compression spring 253 rebounds, thereby driving the fixing rod 251 to be inserted into the inside of the fixing hole 24, thereby completing the assembly of the retractor.

[0064] The present invention further provides a method for using an automatic anal retractor, comprising the following steps:

[0065] S1: When using the retractor, first put the strap 65 on the patient's waist so that the ring 1 is attached to the patient's buttocks. The control component 62 controls the motor 63 to start. The motor 63 starts to drive the roller 66 to rotate. The roller 66 rotates to drive the strap 65 to roll on the surface of the roller 66, thereby tightening the strap 65 to prevent the ring 1 from shaking left and right on the patient's buttocks when the retractor is in use, thereby causing secondary damage to the patient's anus. When the strap 65 is tightened too tight, the pressure sensor 622 will be subjected to the pressure of the patient's belly. The pressure sensor 622 will convert the monitored pressure signal into an electrical signal and transmit it to the controller 621. The controller 621 controls the motor 63 to turn off, thereby automatically tightening the strap 65.

[0066] S2: When the retractor is used, the expansion plate body 5 located at the center of the circular ring 1 is inserted into the patient's anus, and then the pull ring 31 is pulled, and the pull ring 31 drives the fixing ring 4 to slide upward. Since the expansion plate body 5 is arranged in an inclined shape, the lower end of the expansion plate body 5 will get stuck to the skin inside the anus, and the upward movement of the fixing ring 4 will drive the oblique connecting rod 33 to slide upward. Due to the structural setting of the oblique connecting rod 33, the center of gravity is toward the outside of the circular ring 1. At this time, the oblique connecting rod 33 will drive the sliding rod 37 to slide outward, and the sliding of the sliding rod 37 outward will drive the expansion plate body 5 to expand the anus. When the fixing ring 4 moves upward, although it will drive the oblique connecting rod 33 to move upward, at this time, the fixing ring 4 will drive the buffer spring 342 to stretch, and the stretching of the buffer spring 342 will drive the inner rod 341 to slide inside the outer rod 343, so that the rising height of each group of oblique connecting rods 33 can be adjusted accordingly, thereby avoiding the problem of the sliding rod 37 being stuck when sliding;

[0067] S3: After the expansion plate synchronizes with the external expansion mechanism 3 to expand the anus, in order to prevent the anus from being expanded too much, the pulling force on the pull ring 31 is appropriately reduced at this time, by rotating the turning handle 713, the turning handle 713 drives the rotating rod 714 to rotate, the rotating rod 714 drives the bevel gear 2 715 to rotate, the bevel gear 2 715 drives the bevel gear 1 711 to rotate, the bevel gear 1 711 drives the threaded rod 72 to rotate, the threaded rod 72 drives the telescopic rod 74 to rotate, because the slider 73 on the side of the telescopic rod 74 is stuck in the slide groove 75 on the inner wall of the slide rod 37, the threaded rod 72 can drive the telescopic rod 74 to slide outward at this time, so as to fine-tune the tension of the anus to avoid damage to the anus;

[0068] S4: In order to facilitate the disassembly and storage of the retractor, by pulling the handle 255, the handle 255 pulls the pull rod 254, and the pull rod 254 pulls the limit plate 252 and the fixed rod 251. At the same time, the limit plate 252 will drive the compression spring 253 to be compressed. At this time, the insertion rod 23 on the side of the tripod 32 can be pulled out from the socket 21 inside the fixed seat 22, thereby completing the disassembly of the retractor so that it can be stored separately to avoid the retractor being too large and occupying a large space when stored. When the retractor needs to be assembled, the insertion rod 23 is inserted into the inside of the socket 21 again. At this time, the handle 255 is released, and the compression spring 253 rebounds, thereby driving the fixed rod 251 to be inserted into the inside of the fixed hole 24, thereby completing the assembly of the retractor.

At this time, the oblique connecting rod 33 will drive the sliding rod 37 to slide outward, and the sliding of the sliding rod 37 to the outside will drive the expansion plate The main body 5 stretches the anus. When the fixing ring 4 moves upward, it will drive the oblique connecting rod 33 to move upward. At this time, the fixing ring 4 will drive the buffer spring 342 to stretch. The stretching of the buffer spring 342 will drive the inner rod 341 to slide inside the outer rod 343, so that the rising height of each group of oblique connecting rods 33 can be adjusted accordingly, thereby avoiding the problem of the sliding rod 37 getting stuck when sliding; when the expansion plate synchronizes with the external expansion mechanism 3 to stretch the anus, in order to prevent the anus from being stretched too much, the pulling force on the pull ring 31 is appropriately reduced at this time, by turning the handle 713, the handle 713 rotates to drive the rotating rod 714 rotates, the rotating rod 714 rotates to drive the bevel gear 2 715 to rotate, the bevel gear 2 715 rotates to drive the bevel gear 1 711 to rotate, the bevel gear 1 711 rotates to drive the threaded rod 72 to rotate, the threaded rod 72 rotates to drive the telescopic rod 74 to rotate, because the slider 73 on the side of the telescopic rod 74 is stuck in the slide groove 75 on the inner wall of the slide rod 37, the threaded rod 72 rotates to drive the telescopic rod 74 to slide outward, thereby fine-tuning the tension of the anus to avoid anal injury; when using the retractor, first put the strap 65 on the patient's waist position so that the ring 1 is attached to the patient's buttocks, and control the group Component 62 controls motor 63 to start, motor 63 starts to drive roller 66 to rotate, roller 66 rotates to drive strap 65 to roll on the surface of roller 66, thereby tightening strap 65, and preventing the ring 1 from swinging left and right on the patient's buttocks when the retractor is in use, thereby causing secondary damage to the patient's anus. When strap 65 is too tight, pressure sensor 622 will be subjected to pressure from the patient's belly, and pressure sensor 622 will convert the monitored pressure signal into an electrical signal and transmit it to controller 621, and controller 621 controls motor 63 to turn off, thereby automatically tightening strap 65;In order to facilitate the disassembly and storage of the retractor, by pulling the pull handle 255, the pull handle 255 pulls the pull rod 254, and the pull rod 254 pulls the limit plate 252 and the fixing rod 251, and the limit plate 252 will drive the compression spring 253 to compress, and then the insertion rod 23 on the side of the tripod 32 can be pulled out from the insertion hole 21 inside the fixing seat 22, so as to complete the disassembly of the retractor, so as to store it separately, and avoid the retractor being too large to occupy a large space when stored.
