Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a folding fixation chair for postoperative use. Background Technology

[0002] Vitreoretinal diseases are a serious and complex category of ophthalmic diseases, typically involving symptoms such as vitreous opacity, vitreous hemorrhage, retinal detachment, retinal tears, and macular degeneration. Patients with vitreoretinal diseases are usually required to lie prone for a long period of time after surgery, and maintain the same posture for more than 20 hours a day, that is, face down in a horizontal position, so that the intraocular filler can press against the retina to the maximum extent and help the detached retina to reposition.

[0003] Currently, when using fixation devices, patients typically sit on top of the device with their heads placed directly on the horizontal panel surface. While this method can temporarily keep the patient's head horizontal, the lack of other fixation structures means that the head often moves after the patient maintains this posture for a certain period, thus affecting the recovery effect. Furthermore, existing devices only allow patients to maintain one posture and cannot be adjusted as needed, which limits their use. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art by proposing a folding fixation chair for postoperative use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A postoperative folding fixation chair includes a head fixation structure and a base. The head fixation structure includes a base plate, a panel on the top of the base plate, and racks symmetrically fixed to the bottom of the panel. Gears are symmetrically rotatably connected to the inner wall of the base plate, with the teeth of two gears meshing with the teeth of two racks. A support rod is fixedly connected to the top of the gears, and a head limiting structure is fixedly installed at the end of the support rod away from the gear. A telescopic reset structure is fixedly installed between one end of the rack and the inner wall of the base plate. A chin rest block is slidably connected to the inner wall of the panel, and a connecting plate is fixedly connected to the bottom of the chin rest block and inside the panel. An elastic element A is fixedly connected between the bottom of the connecting plate and the inner wall of the panel. A connecting rod is fixedly connected to the bottom of the connecting plate, and a handle is fixedly installed at the end of the connecting rod away from the connecting plate, with the handle located below the base plate.

[0007] In the aforementioned postoperative folding fixation chair, the head limiting structure includes a rotating seat. A screw is threadedly connected to the inner wall of the rotating seat. An adjustment knob is fixedly installed at one end of the screw, and a lifting seat is rotatably connected to the other end of the screw. The outer wall of the lifting seat is slidably connected to the inner wall of the rotating seat. A limiting post is fixedly connected to the inner wall of the lifting seat. A positioning plate is slidably connected to the outer wall of the limiting post. An elastic element B is fixedly connected between the outer wall of the positioning plate and the inner wall of the lifting seat. The elastic element B is sleeved on the outside of the limiting post. A head limiting plate is fixedly installed at the end of the positioning plate away from the limiting post.

[0008] In the aforementioned postoperative folding fixation chair, a seat and a chest plate are provided above the base. Hinges are fixedly installed on the outer walls of both the seat and the chest plate. The seat, chest plate, and head fixation structure are sequentially connected by the hinges. A longitudinal sliding structure is fixedly installed on the outer wall of the head fixation structure away from the hinges. A column is slidably connected to the inner wall of the base. The longitudinal sliding structure is slidably connected to the inner side of the column. A threaded column is rotatably connected to the inner wall of the base. The outer wall of the threaded column is threadedly connected to the inner wall of the column. A swivel is fixedly installed at one end of the threaded column.

[0009] In the above-mentioned postoperative folding fixation chair, the interior of the longitudinal sliding structure includes a connecting block, the outer wall of the connecting block is symmetrically fixedly connected to a mounting plate, and the outer wall of the mounting plate is fixedly mounted with rollers.

[0010] In the above-mentioned postoperative folding fixation chair, the outer wall of the panel is symmetrically fixedly connected with limit blocks, the outer wall of the base plate is symmetrically provided with limit grooves, and the two limit blocks are respectively slidably connected to the inner walls of the two limit grooves.

[0011] In the above-mentioned postoperative folding fixation chair, the outer wall of the chest plate is symmetrically fixed with adjusting columns, the outer wall of the adjusting columns is slidably connected with adjusting sleeves, the inner wall of the adjusting sleeves is threaded with a fastening knob A, the adjusting sleeves are fixedly connected to the adjusting columns through the fastening knob A, and the outer walls of the two adjusting sleeves on opposite sides are rotatably connected with arm plates.

[0012] In the above-mentioned postoperative folding fixation chair, a support seat is symmetrically fixedly connected to the top of the base, a pedal is rotatably connected to the inner wall of the support seat, and a fastening knob B is threadedly connected to the inner wall of the support seat. The pedal is fixedly connected to the support seat through the fastening knob B.

[0013] In the aforementioned postoperative folding fixation chair, the bottom of the seat is hinged with a folding leg plate, and a support leg is fixedly connected between the bottom of the seat and the top of the base.

[0014] Compared with existing technologies, the advantages of this postoperative folding fixation chair are:

[0015] The patient places their head on top of the head fixation structure and rests their chin against the chin rest block. Then, the patient slowly lowers their head. As the patient lowers their head, the chin rest block pulls the panel closer to the patient's body until the head is horizontal. When the panel moves, the rack drives the gear to rotate. The gear drives the head limiting structure to rotate above the head through the support rod, thus limiting the head and preventing the patient's head from rotating, ensuring the recovery effect.

[0016] When the patient needs to release the head fixation, the patient can pull down the handle. The handle pulls the chin rest block into the panel through the connecting rod. As the chin rest block is no longer restrained, the panel will move away from the patient's body under the action of the telescopic reset structure. At the same time, the gear will reverse to remove the head restraint structure from the patient's head, thus releasing the head restraint. This achieves the effect of easy release of fixation. Fixation and release do not require the help of others and are easy to use.

[0017] The height of the lifting seat can be adjusted by rotating the adjustment knob, making the device suitable for patients with different head circumferences. The head limiting plate is arc-shaped, so it can fit the head and better limit the head. Through the cooperation of the elastic element B and the positioning plate, it can play a buffering role to prevent injury to the patient's head. At the same time, each head limiting plate corresponds to an individual elastic element B, so each head limiting plate adjusts itself to a suitable position when in contact with the head, thus adapting to patients with different head shapes and achieving better fixation.

[0018] Rotating the swivel ring allows the threaded column to rotate, thus enabling lateral adjustment of the column's position. Since the head fixation structure, chest plate, and seat plate are hinged together, the angle between them changes as the column moves. Patients can adjust these settings to increase their comfort. The head fixation structure is connected to the column via a longitudinal sliding structure, ensuring that it remains horizontal regardless of adjustments, thus guaranteeing no impact on recovery.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] Reference Figures 1-12 A postoperative folding fixation chair includes a head fixation structure 1 and a base 3. The head fixation structure 1 includes a base plate 101, a panel 102 on the top of the base plate 101, and racks 103 symmetrically fixedly mounted on the bottom of the panel 102. Gears 104 are symmetrically rotatably connected to the inner wall of the base plate 101, with the teeth of the two gears 104 meshing with the teeth of the two racks 103 respectively. A support rod 105 is fixedly connected to the top of the gears 104, and a head limiting structure 2 is fixedly mounted on the end of the support rod 105 away from the gears 104. A telescopic reset structure 106 is fixedly installed between one end of 03 and the inner wall of the base plate 101. A chin block 107 is slidably connected to the inner wall of the panel 102. A connecting plate 108 is fixedly connected to the bottom of the chin block 107 and located inside the panel 102. An elastic element A109 is fixedly connected between the bottom of the connecting plate 108 and the inner wall of the panel 102. A connecting rod 110 is fixedly connected to the bottom of the connecting plate 108. A handle 111 is fixedly installed at the end of the connecting rod 110 away from the connecting plate 108. The handle 111 is located below the base plate 101.

[0035] In this embodiment, during use, the patient places their head above the head-fixing structure 1 and rests their chin against the chin rest block 107. The patient then slowly lowers their head. During this process, because the patient's chin is against the chin rest block 107, the panel 102 is pulled closer to the patient's body until the head is horizontal. As the panel 102 moves, the rack 103 drives the gear 104 to rotate. The gear 104, through the support rod 105, drives the head-limiting structure 2 to rotate above the head, thus limiting the head and preventing it from rotating. To ensure effective recovery, when the patient needs to release the fixation on the head, the patient can pull down the handle 111. The handle 111, through the connecting rod 110, pulls the chin block 107 into the interior of the panel 102. As the chin block 107 is no longer restrained, the panel 102 will move away from the patient's body under the action of the telescopic reset structure 106. At the same time, the gear 104 will reverse to remove the head restraint structure 2 from the patient's head, thus releasing the restriction on the head. This achieves the effect of conveniently releasing the fixation. Neither fixing nor releasing the fixation requires assistance from others, making it easy to use.

[0036] Specifically, the head limiting structure 2 includes a rotating seat 201. A screw 202 is threadedly connected to the inner wall of the rotating seat 201. An adjustment knob 203 is fixedly installed at one end of the screw 202. A lifting seat 204 is rotatably connected to the other end of the screw 202. The outer wall of the lifting seat 204 is slidably connected to the inner wall of the rotating seat 201. A limiting post 205 is fixedly connected to the inner wall of the lifting seat 204. A positioning plate 206 is slidably connected to the outer wall of the limiting post 205. An elastic element B207 is fixedly connected between the outer wall of the positioning plate 206 and the inner wall of the lifting seat 204. The elastic element B207 is sleeved on the outside of the limiting post 205. A head limiting plate 208 is fixedly installed at the end of the positioning plate 206 away from the limiting post 205.

[0037] In this embodiment, the height of the lifting seat 204 can be adjusted by rotating the adjustment knob 203, so that the device can be adapted to patients with different head circumferences. The head limiting plate 208 is arc-shaped, so it can fit the head and better limit the head. Through the cooperation of the elastic element B207 and the positioning plate 206, a buffering effect can be achieved to prevent injury to the patient's head. At the same time, each head limiting plate 208 corresponds to an individual elastic element B207. Therefore, each head limiting plate 208 adjusts itself to a suitable position when in contact with the head, so as to adapt to patients with different head shapes and achieve better fixation effect.

[0038] Specifically, a seat plate 4 and a chest plate 5 are provided above the base 3. Hinges 6 are fixedly installed on the outer walls of both the seat plate 4 and the chest plate 5. The seat plate 4, the chest plate 5 and the head fixing structure 1 are connected in sequence through the hinges 6. A longitudinal sliding structure 7 is fixedly installed on the outer wall of the head fixing structure 1 away from the hinges 6. A column 8 is slidably connected to the inner wall of the base 3. The longitudinal sliding structure 7 is slidably connected to the inner side of the column 8. A threaded column 9 is rotatably connected to the inner wall of the base 3. The outer wall of the threaded column 9 is threadedly connected to the inner wall of the column 8. A swivel ring 10 is fixedly installed at one end of the threaded column 9.

[0039] In this embodiment, rotating the rotating ring 10 can drive the threaded column 9 to rotate, thereby allowing the position of the column 8 to be adjusted laterally. Since the head fixation structure 1, chest plate 5, and sitting plate 4 are hinged by the hinge 6, the angle between them will change when the column 8 moves. The patient can adjust it at will to increase their comfort according to their needs. The head fixation structure 1 is connected to the column 8 through the longitudinal sliding structure 7, so no matter how it is adjusted, the head fixation structure 1 will always be in a horizontal state, thus ensuring that the recovery effect will not be affected.

[0040] Specifically, the longitudinal sliding structure 7 includes a connecting block 701 inside, and a mounting plate 702 is symmetrically fixedly connected to the outer wall of the connecting block 701. Rollers 703 are fixedly installed on the outer wall of the mounting plate 702.

[0041] In this embodiment, the longitudinal sliding structure 7 is located inside the column 8 and can slide inside the column 8. The longitudinal sliding structure 7 has a limiting effect, so that the head fixing structure 1 will always remain horizontal when it moves up and down. At the same time, the roller 703 provided in the longitudinal sliding structure 7 converts the sliding friction into rolling friction, reducing the resistance generated during sliding.

[0042] Specifically, the outer wall of the panel 102 is symmetrically fixedly connected with limit blocks 112, and the outer wall of the base plate 101 is symmetrically provided with limit grooves 113. The two limit blocks 112 are slidably connected to the inner walls of the two limit grooves 113 respectively.

[0043] In this embodiment, the panel 102 is limited by the cooperation of the limiting block 112 and the limiting groove 113, so that the panel 102 will only move in a preset direction, thereby increasing the stability of the device during use.

[0044] Specifically, the outer wall of the chest plate 5 is symmetrically fixedly connected with adjusting columns 11, the outer wall of the adjusting columns 11 is slidably connected with adjusting sleeves 12, the inner wall of the adjusting sleeves 12 is threadedly connected with fastening knobs A13, the adjusting sleeves 12 are fixedly connected to the adjusting columns 11 through the fastening knobs A13, and the outer walls of the two adjusting sleeves 12 on the opposite sides are rotatably connected with arm plates 14.

[0045] In this embodiment, the arm plate 14 is designed to provide a fulcrum for the patient's arm. The arm plate 14 can also rotate, allowing the patient to swing their arm during actual use, which facilitates certain movements. The adjusting sleeve 12 is fixed by the fastening knob A13. By loosening the fastening knob A13, the position of the adjusting sleeve 12 can be adjusted, thereby adjusting the position of the arm plate 14.

[0046] Specifically, a support base 15 is symmetrically fixedly connected to the top of the base 3, a pedal 16 is rotatably connected to the inner wall of the support base 15, and a fastening knob B17 is threadedly connected to the inner wall of the support base 15. The pedal 16 is fixedly connected to the support base 15 through the fastening knob B17.

[0047] In this embodiment, the pedal 16 is designed to provide a fulcrum for the patient's foot, and the fastening knob B17 allows for adjustment of the angle of the pedal 16.

[0048] Specifically, a folding leg plate 18 is hinged to the bottom of the seat plate 4, and a support leg 19 is fixedly connected between the bottom of the seat plate 4 and the top of the base 3.

[0049] In this embodiment, by rotating the folding leg plate 18, the folding leg plate 18 can be flipped to be horizontal with the seat plate 4. At this time, the seat plate 4, chest plate 5 and head fixing structure 1 are adjusted to be horizontal, and the patient can lie on the device. The folding leg plate 18 can support the patient's legs.

[0050] The working principle and usage of this invention are as follows: Rotating the rotating ring 10 drives the threaded column 9 to rotate, thereby allowing the position of the upright column 8 to be adjusted laterally. Since the head fixation structure 1, chest plate 5, and seat plate 4 are hinged by the hinge 6, the angle between them changes when the upright column 8 moves. Patients can adjust these components freely to increase their comfort. The head fixation structure 1 is connected to the upright column 8 through the longitudinal sliding structure 7, so no matter how it is adjusted, the head fixation structure 1 will always remain in a horizontal state, thus ensuring that it will not affect the patient's comfort. After the device is properly adjusted, the patient places their head above the head-fixing structure 1 and rests their chin against the chin rest block 107. The patient then slowly lowers their head. During this process, because the patient's chin is against the chin rest block 107, the panel 102 is pulled closer to the patient's body until the head is horizontal. As the panel 102 moves, the rack 103 drives the gear 104 to rotate. The gear 104, through the support rod 105, drives the head-limiting structure 2 to rotate above the head, thus limiting the head and preventing it from rotating. The device effectively restores the patient's head shape, allowing for easy removal of fixation. Neither fixation nor removal requires assistance, making it convenient to use. The height of the lifting seat 204 can be adjusted by rotating the adjustment knob 203, making the device suitable for patients with different head circumferences. The head limiting plate 208 is arc-shaped, allowing it to conform to the head and better limit its movement. The elastic element B207 and the positioning plate 206 work together to provide cushioning, preventing injury to the patient's head. Each head limiting plate 208 corresponds to an individual elastic element B207, thus ensuring that each head limiting plate... When the positioning plate 208 contacts the head, it automatically adjusts to a suitable position to accommodate patients with different head shapes, resulting in better fixation. When the patient needs to release the fixation on the head, the patient can pull down the handle 111. The handle 111 pulls the chin rest block 107 into the interior of the panel 102 through the connecting rod 110. Since the restriction of the chin rest block 107 is removed, the panel 102 will move away from the patient's body under the action of the telescopic reset structure 106. At the same time, the gear 104 will reverse to remove the head limiting structure 2 from the patient's head, thus releasing the restriction on the head.

[0051] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0052] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
