Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an eyelid stretching device for ophthalmic care. Background Art

[0002] As one of the indispensable medical devices in ophthalmic surgery, the eyelid speculum can prop open the patient's eyelids and expand the surgical field to facilitate surgery (it can still play an auxiliary role in postoperative care). The shape of the eyelid speculum is mostly V-shaped, U-shaped or Y-shaped, including a support arm and an eyelid hook. The rear ends of the two support arms are combined into one as a hand-held part, and the front ends are two symmetrically arranged eyelid hooks. The eyelid hooks are generally arranged in a horizontal L-shaped structure. The vertical part is inserted into the eye socket to fix the eyelid, and the horizontal part is used to limit the depth of the vertical part into the eye socket to prevent the vertical part from causing damage to the eyeball. The knob is used at the rear end of the support arm to adjust and lock the distance between the arm ends.

[0043] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows: Example

[0044] This embodiment introduces the specific structure of an eyelid opening device for ophthalmic care. Figure 1-Figure 10 As shown, it includes a fixed angle piece 4, a first bridging piece 1 arranged at one end of the fixed angle piece 4, a second bridging piece 3 arranged at the other end of the fixed angle piece 4, and a molding piece 2 arranged between the first bridging piece 1 and the second bridging piece 3, a first adapting structure 5 is arranged between the first bridging piece 1 and the fixed angle piece 4, a second adapting structure 6 is arranged between the second bridging piece 3 and the fixed angle piece 4, a second adjusting structure 8 is arranged between the first bridging piece 1 and the molding piece 2, and a first adjusting structure 7 is arranged between the second bridging piece 3 and the molding piece 2;

[0045] like Figure 1 , Figures 5 to 7 As shown, the first adaptable structure 5 includes a first sliding rod 501 and a first sliding sleeve 502. The surface of one end of the first sliding rod 501 is processed with a first limiting head 504, and the interior of the first sliding sleeve 502 is processed with a first limiting slideway 503.

[0046] One end of the first slide bar 501 is fixed to the top of one end of the first mounting member 1, and one end of the first sliding sleeve 502 is fixed to the top of one end of the fixed angle member 4. The first limiting slide 503 is set to be L-shaped, so that the short side of the first limiting slide 503 can perform the limiting function, and the long side of the first limiting slide 503 can perform the track function. When one end of the first slide bar 501 slides inside the first sliding sleeve 502, the first limiting head 504 can be synchronously controlled to slide inside the first limiting slide 503, and the first limiting head 504 and the short side of the first limiting slide 503 are used to limit the first slide bar 501 from being separated from the inside of the first sliding sleeve 502.

[0047] like Figure 1 , Figure 3 and Figure 4 As shown, the first adjustment structure 7 includes a first screw rod 702, one end of which is processed with a round rod 704, the outer portion of the first screw rod 702 is threadedly connected to a first threaded sleeve 701, and the outer portion of the round rod 704 is sleeve-connected to a first support sleeve 703;

[0048] Among them, one end of the first threaded sleeve 701 is fixed to the top of one end of the second mounting member 3, and one end of the first support sleeve 703 is fixed to the top of one end of the molded member 2. In order to prevent the round rod 704 from escaping from the inside of the first support sleeve 703, when the first screw rod 702 is rotated, the threaded connection between the first screw rod 702 and the first threaded sleeve 701 can be adjusted to control the distance between the first support sleeve 703 and the first threaded sleeve 701, such as Figure 3 and Figure 4 As shown, a ring channel is processed at one end of the round rod 704, and a clamping ring 705 is connected inside the ring channel in a clamping manner. By locating the first screw rod 702 and the clamping ring 705 at both ends of the first support sleeve 703 respectively, the round rod 704 can be restricted from moving inside the first support sleeve 703 along the direction of its axis;

[0049] At the same time, when adjusting the threaded connection between the first screw rod 702 and the first threaded sleeve 701, the distance between the first threaded sleeve 701 and the first support sleeve 703 can be controlled by means of the clamping ring 705 at one end of the round rod 704 cooperating with one end of the first screw rod 702 (at this time, one end of the first sliding rod 501 slides inside the first sliding sleeve 502, and the second adjustment structure 8 is connected between the first scaffolding member 1 and the molding member 2, and the second adaptation structure 6 is connected between the second scaffolding member 3 and the fixed angle member 4), so that the first adjustment structure 7 can control the distance between the second scaffolding member 3 and the molding member 2, and the first scaffolding member 1 and the fixed angle member 4 under the support of the first adaptation structure 5;

[0050] like Figure 1 , Figure 8 and Fig. 9 As shown, the second adapting structure 6 includes a second sliding rod 602 and a second sliding sleeve 601. The surface of one end of the second sliding rod 602 is processed with a second limiting head 604, and the interior of the second sliding sleeve 601 is processed with a second limiting slideway 603;

[0051] By setting the second limiting slide 603 into an L shape, the short side of the second limiting slide 603 performs the limiting function, and the long side of the second limiting slide 603 performs the track function. When the second slide bar 602 slides inside the second slide sleeve 601, the second limiting head 604 sliding inside the second limiting slide 603 can be used to limit the second slide bar 602 from being separated from the inside of the second slide sleeve 601.

[0052] like Figure 1 , Figure 4 and Figure 5 As shown, the second adjustment structure 8 includes a second screw rod 802, one end of the second screw rod 802 is externally threadedly connected to a second threaded sleeve 803, the other end of the second screw rod 802 is externally sleevedly connected to a second support sleeve 801, and the middle part of the second screw rod 802 is sleevedly connected to a spring 804;

[0053] Among them, one end of the second support sleeve 801 is fixed to the top of one end of the molded part 2, and one end of the second threaded sleeve 803 is fixed to the top of one end of the first mounting member 1. By processing the isolation ring 805 on one end of the second threaded sleeve 803 and the second support sleeve 801, the two ends of the spring 804 are respectively sleeved on the outside of the two isolation rings 805. At this time, the spring 804 is supported between the surface of one end of the second threaded sleeve 803 and the surface of one end of the second support sleeve 801. When the second screw rod 802 is rotated to adjust the threaded connection between it and the second threaded sleeve 803, and the spring 804 is rotated to adjust the threaded connection between it and the second threaded sleeve 803. Under the support of the second adaptive structure 6, the distance between the second supporting sleeve 801 and the second threaded sleeve 803 is controlled (at this time, one end of the second sliding rod 602 slides inside the second sliding sleeve 601, and the second limiting head 604 slides at the long side portion of the second limiting slide 603 and is limited by the short side portion. Because the first adaptive structure 5 is connected between the first scaffolding piece 1 and the fixed angle piece 4, and the first adjustment structure 7 is connected between the forming piece 2 and the second scaffolding piece 3), the second adjustment structure 8 can control the distance between the first scaffolding piece 1 and the forming piece 2, the fixed angle piece 4 and the second scaffolding piece 3 under the support of the second adaptive structure 6. Example

[0054] Based on Example 1, this example introduces the specific structure of the eyelid stretching device for ophthalmic care. The fixed angle piece 4 and one side of the first mounting piece 1, the molding piece 2 and one side of the second mounting piece 3 are all provided with eyelid stretching pieces 9. The eyelid stretching pieces 9 include a pad 901. The tops of both ends of the pad 901 are processed with first arc-shaped arms 902. One end of the two first arc-shaped arms 902 is integrally formed with a C-shaped ring 904.

[0055] By fastening the two C-shaped rings 904 to the second mounting piece 3 and the molding piece 2 or the first mounting piece 1 and the fixed angle piece 4, the two eyelid supports 9 can be fixed to one side of the fixed angle piece 4 and the first mounting piece 1 and one side of the molding piece 2 and the second mounting piece 3 respectively.

[0056] Secondly, by using plastic to make the first arc-shaped arm 902 and the second arc-shaped arm 903, the first arc-shaped arm 902 and the second arc-shaped arm 903 have certain elastic properties while maintaining certain rigidity. When the first adjustment structure 7 cooperates with the first adaptable structure 5 to control the distance between the first mounting member 1 and the fixed angle member 4, the forming member 2 and the second mounting member 3, the second arc-shaped arm 903 can be bent.

[0057] At the same time, when the first mounting member 1, the molding member 2, the second mounting member 3 and the fixing angle member 4 are arranged in a rectangular state and their bottoms are supported on the back of the patient's eyelids and the eyelids are enlarged, the surface of the pad strip 901 can be attached to the skin of the patient's eyelid surrounding area through the first arc-shaped arm 902, thereby ensuring the eyelid opening effect of the patient and the fixing effect of the device;

[0058] Furthermore, by using silicone material to make the pad 901, when the distance between the second mounting piece 3 and the molding piece 2, the fixed angle piece 4 and the first mounting piece 1 reaches the maximum, the pad 901 is in a stretched state. When the distance between the second mounting piece 3 and the molding piece 2, the fixed angle piece 4 and the first mounting piece 1 is adjusted by the first adjustment structure 7 under the support of the first adaptive structure 5, the pad 901 can be converted from a stretched state to a relaxed state, and there will be no local bending of the pad 901, which affects the surface of the pad 901 and the fit of the patient's skin.

[0059] Specifically, before using the eyelid stretching device for ophthalmic care to stretch the patient's eyelids:

[0060] First, take out the fixed angle piece 4, insert one end of the first slide bar 501 fixed to the first mounting piece 1 into one end of the first slide sleeve 502, so that the first limit head 504 on the first slide sleeve 502 enters the short side of the first limit slideway 503, and after rotating the first slide bar 501, the first limit head 504 enters the long side of the first limit slideway 503, so that the first slide bar 501 can slide inside the first slide sleeve 502;

[0061] At the same time, a section of the second slide bar 602 fixed to the molded part 2 is inserted into the interior of one end of the second slide sleeve 601, so that the second limit head 604 at one end of the second slide bar 602 enters the short side portion of the second limit slideway 603. After the second slide bar 602 is rotated, the second limit head 604 enters the long side portion of the second limit slideway 603, so that the second slide bar 602 slides inside the second slide sleeve 601, and drives the second limit head 604 to slide inside the long side portion of the second limit slideway 603;

[0062] Then, one end of the round rod 704 is inserted into the first support sleeve 703, and a clamping ring 705 is clamped inside the annular groove at one end of the round rod 704 to restrict the round rod 704 from being separated from the first support sleeve 703, so that the round rod 704 can only rotate inside the first support sleeve 703;

[0063] Next, one end of the first screw rod 702 is placed on one end of the first threaded sleeve 701, and after the first screw rod 702 is rotated, one end of the first threaded sleeve 701 is threadedly connected to the interior of the first threaded sleeve 701;

[0064] Subsequently, the first slide bar 501 on the first mounting member 1 is controlled to slide inside the first slide sleeve 502, so that the second support sleeve 801 on the molding member 2 is coaxial with the second threaded sleeve 803 on the first mounting member 1, and the second screw rod 802 is passed through the second support sleeve 801, and after the spring 804 is sleeved, one end of the second screw rod 802 is threadedly connected to the inside of the second threaded sleeve 803, so that the spring 804 is supported between the second support sleeve 801 and the second threaded sleeve 803;

[0065] Finally, the two C-rings 904 on the eyelid support 9 are respectively fastened to the forming piece 2 and the second mounting piece 3 or the first mounting piece 1 and the fixed angle piece 4, ensuring that one side of the first mounting piece 1 and the fixed angle piece 4 and one side of the forming piece 2 and the second mounting piece 3 are both equipped with the eyelid support 9.

[0066] When using the eyelid retractor for ophthalmic care to retract the patient's eyelids:

[0067] First, according to the size of the patient's eyelids and the elasticity of the skin, the threaded connection between the first screw 702 and the first threaded sleeve 701 and the threaded connection between the second screw 802 and the second threaded sleeve 803 are adjusted;

[0068] Then, the bottoms of the first mounting piece 1, the molding piece 2, the second mounting piece 3 and the fixed angle piece 4 are all extended to the back of the patient's eyelid, and when the threaded connection between the second screw rod 802 and the second threaded sleeve 803 is adjusted, the second support sleeve 801 and the second threaded sleeve 803 are moved away from each other under the support of the spring 804. In this action, (one end of the second slide rod 602 slides inside the second slide sleeve 601, and the second limit head 604 slides at the long side portion of the second limit slideway 603 and is limited by the short side portion), the first adaptive structure 5 is connected between the first mounting piece 1 and the fixed angle piece 4, and the first adjustment structure 7 is connected between the molding piece 2 and the second mounting piece 3, thereby driving the first mounting piece 1 and the molding piece 2, the second mounting piece 3 and the fixed angle piece 4 to move away from each other;

[0069] At the same time, when adjusting the threaded connection between the first screw rod 702 and the first threaded sleeve 701, the first threaded sleeve 701 and the first screw rod 702 are moved away from each other in this state (one end of the first slide rod 501 slides inside the first slide sleeve 502, and the first limit head 504 slides at the long side of the first limit slideway 503 and is limited by the short side), the second adjustment structure 8 is connected between the first scaffolding member 1 and the forming member 2, and the second adaptation structure 6 is connected between the second scaffolding member 3 and the fixed angle member 4, thereby driving the forming member 2 and the second scaffolding member 3, the first scaffolding member 1 and the fixed angle member 4 to move away from each other;

[0070] Next, with the help of the first supporting piece 1, the shaping piece 2, the second supporting piece 3 and the fixed angle piece 4 expanding in all directions, the patient's eyelids can be stretched open to expose the patient's lesions. When the distances between the first supporting piece 1 and the fixed angle piece 4, the shaping piece 2 and the second supporting piece 3, the first supporting piece 1 and the shaping piece 2, and the second supporting piece 3 and the fixed angle piece 4 are adjusted, the second arc arm 903 on the eyelid support piece 9 is first transformed from a compressed bending state to a relaxed state, and the pad strip 901 is supported on the skin on the front of the patient's eyelid through the first arc arm 902, which can ensure that the device is fixed on the patient's eyelid to complete the stretching effect.

[0071] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
