Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically to a device for eyelid implantation surgery. Background Technology

[0002] Peripheral facial paralysis can lead to incomplete eyelid closure. Incomplete eyelid closure refers to the inability of the upper and lower eyelids to close completely, resulting in partial exposure of the eyeball, also known as lagophthalmos. Incomplete eyelid closure can cause significant eye pain, and can also lead to poor eye hygiene, foreign body accumulation, or excessive tearing. In some cases, it can also cause decreased vision, corneal ulcers, and conjunctival congestion.

[0003] Closing the eyelids by suturing them often results in significant trauma, poor appearance, and even loss of eye function. To avoid damage to the eye caused by eyelid suturing and to protect the eyeball to the greatest extent possible, a metal plate can be implanted inside the eyelid. The weight of the metal plate will then close the eye.

[0004] The specific method for inserting a metal plate into the eyelid includes: after anesthetizing the eyelid, making an incision in the eyelid with a scalpel, inserting the metal plate into the eyelid through the incision, and then suturing the incision to fix it and wrap the metal plate. Therefore, it is necessary to design a device that facilitates the placement of the metal plate in the eyelid by the surgeon, in order to reduce the operation time and improve the safety of the surgical procedure. Summary of the Invention

[0022] The push-pull rod moves forward, and the blade placed in the slide groove is pushed out of the fixed block;

[0023] The push-pull rod moves backward, and the blade is retracted into the groove of the fixing block.

[0024] Optionally, the cutter head device is used to perform the opening and closing action;

[0025] The cutter head device includes a widening assembly, which includes structural components and opening / closing components;

[0026] The rear end of the structural component is connected to the push-pull rod, and the front end is connected to the opening / closing component;

[0027] The opening and closing components include a first opening and closing component and a second opening and closing component arranged symmetrically about the direction of movement of the push-pull rod;

[0028] The push-pull rod moves forward, pushing the first and second opening / closing components to open through the structural components;

[0029] The push-pull rod moves backward, pulling the first and second opening / closing components to close via the structural components.

[0030] Optionally, the widening assembly further includes a fixing member and a widening connecting shaft;

[0031] The first opening / closing component and the second opening / closing component are connected to the fixing component by a shaft hole via the wide-open connecting shaft;

[0032] The push-pull rod drives the structural component, which in turn causes the first and second opening / closing components to rotate axially around the wide-opening connecting shaft.

[0033] The beneficial effects of this invention are as follows:

[0034] The device for eyelid graft placement surgery provided by this invention enables the use of a single instrument to perform delivery or opening / closing actions within the same surgical procedure using a blade device.

Detailed Implementation

[0041] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] In the description of this invention, it should be noted that the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the 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, and therefore should not be construed as a limitation of the invention. For ease of understanding, in this invention, "front" refers to the distal end, and "rear" refers to the proximal end, etc. Figure 5 and Figure 6For example, directions perpendicular to the front and back and parallel to the paper are "up" and "down", while directions perpendicular to the front and back and passing through the paper are "left" and "right". Figure 5 This is a view from the left side of the device used for eyelid implantation surgery. Figure 6 This is a view from the right side of the device used for eyelid flap insertion surgery. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] like Figure 1 As shown, the device for eyelid implantation surgery of the present invention includes a pushing device 1, a driving device 2, and a cutting head device 3. The rear end of the pushing device 1 is connected to the driving device 2, and the front end is connected to the cutting head device 3. The surgeon controls the driving device to drive the pushing device 1 and the cutting head device 3 in sequence to realize various operations of eyelid implantation surgery.

[0045] The pushing device 1 includes a connecting pipe 12, the front end of which is connected to an outer tube body 15. The outer tube body 15 has a rectangular through groove, within which a push-pull rod 152 is housed. The push-pull rod 152 is made of flexible metal material and can be shaped and deformed according to the various channels and grooves. The connecting pipe 12 and the outer tube body 15 are detachably connected; removing the outer tube body 15 and the connecting pipe 12 allows for quick replacement of the push-pull rod 152 and the components within the connecting pipe 12. The front end of the outer tube body 15 is detachably connected to a cutter head device 3.

[0046] The drive device 2 includes a screw 22, and a nut 21 is connected to the outside of the screw 22. Rotating the nut 21 can drive the screw 22 to reciprocate forward or backward.

[0047] The connecting tube 12 includes a first end face 121 at the rear end and a second end face 122 at the front end. The nut 21 includes a first end face 211 at the rear end and a second end face 212 at the front end. The first end face 121 of the connecting tube and the second end face 212 of the nut are movably connected. Specifically, the second end face 212 of the nut has an O-ring protruding towards the central axis of the nut, and the outer surface of the first end face 121 of the connecting tube has a connecting tube groove corresponding to the O-ring. The nut 21 and the connecting tube 12 are engaged through the O-ring and the connecting tube groove. When the nut 21 is rotated, under the constraint of the connecting tube 12, the nut 21 only rotates axially and does not move forward or backward. The nut 21 drives the screw 22 located in the connecting tube 22 to reciprocate forward or backward through the thread. The driving device 2 also includes a handle 23.

[0048] Figures 3-5 An embodiment of the blade device 3 is shown. In this embodiment, the blade device 3 can be used to push the blade 38, the eyelid plate 6, and the titanium wire 32. The front end of the blade device 3 is generally hemispherical, but the front end face A of the blade device is flattened. The blade device 3 includes a fixing block 31, the rear end of which is connected to the second end face 150 of the outer tube body located at the front end of the outer tube body. The fixing block 31 consists of an upper fixing block 311 and a lower fixing block 312. The lower fixing block 312 is used to provide a channel for the titanium wire 33, the blade 38, and the eyelid plate 6. A boss 3110 extends from the rear end of the upper fixing block 311, and the boss 3110 is inserted into the fixing block insertion hole 31A provided in the lower fixing block 312, so that the upper fixing block 311 and the lower fixing block 312 are connected to form the fixing block 31.

[0049] The rear end of the blade 38 is provided with a convex I-beam hook 35, and the second end 1522 of the push-pull rod is constructed as a concave I-beam hook 1523. The convex I-beam hook 35 and the concave I-beam hook 1523 can be matched and connected, so that the blade 38 is connected to the front end of the push-pull rod 152. Since the blade 38 is connected to the push-pull rod 152, the blade 38 can be pushed by the push-pull rod 152.

[0050] The lower fixing block 312 has a titanium wire hole 33, which communicates with a rectangular through groove in the outer tube 15 and extends through the lower fixing block 312 in the front-back direction. The titanium wire hole 33 is used to accommodate a titanium wire 32. A push rod 40 is connected to the front end face of the second end 1522 of the push-pull rod. The push rod 40 is made of shape memory metal. The push rod 40 is used to push the titanium wire 32. The present invention does not limit the shape of the titanium wire hole 33. When the push-pull rod 152 moves forward, the push-pull rod 152 pushes the push rod 40 and the titanium wire 32 in sequence. The titanium wire 32 can be shaped in the titanium wire hole 33 to the same shape as the titanium wire hole 33 and pushed out of the titanium wire hole 33 to the outside of the cutter head device 3.

[0051] The titanium wire hole 33 is symmetrically provided with a first groove 36 and a second groove 37 on both sides. The first groove 36 and the second groove 37 are connected to the rectangular through groove in the outer tube 15 and pass through the lower fixing block 312 in the front-back direction. The first groove 36 and the second groove 37 are used to accommodate the blade 38. The first groove 36 and the second groove 37 are arc-shaped grooves, and the blade 38 is an arc-shaped blade. The arc-shaped setting direction of the blade 38 matches the first groove 36 and the second groove 37. The first groove 36 and the second groove 37 can also be used to accommodate the eyelid piece 6. The push-pull rod 152 has a flat, long plate-like structure, with a first stop 371 and a second stop 372 on its left and right sides, respectively. The first stop 371 is aligned with the first groove 36, and the second stop 372 is aligned with the second groove 37. The eyelid piece 6 is placed into the first groove 36 and the second groove 37. Taking the eyelid piece 6 being placed in the second groove 37 as an example, when the push-pull rod 152 moves forward, the second stop 372, which is aligned with the second groove 37, moves forward with the push-pull rod 152. The second stop 372 can enter the second groove 37, pushing the eyelid piece located in the second groove 37 out of the blade device 3.

[0052] The titanium wire hole 33 is located inside the lower fixing block 312, and the first groove 36 and the second groove 37 are formed on the surface of the lower fixing block 312. When the blade 38 or the eyelid plate 6 moves in the channel, the upper fixing block 311 is used to cover the blade 38 and the eyelid plate 6, so that the blade 38 and the eyelid plate 6 are not exposed.

[0053] Depending on the surgical method chosen, the direction of the push-pull rod 152 can be changed by the first stop 371 and the second stop 372, and the state of the push-pull rod 152 pushing out and retracting the blade 38 can be changed.

[0054] Figures 7-12 Another embodiment of the cutter head device 3 is shown. In this embodiment, the cutter head device 3 is a wide-opening cutter head, which can be used alone or for secondary widening after the cutter head device 3 of the above embodiment. The cutter head device 3 of this embodiment includes an opening / closing device 39. The opening / closing device 39 is detachably connected to the front end of the outer tube body 15.

[0055] The opening / closing device 39 includes an opening assembly 391 and a cap 392. The opening assembly 391 includes a mating block 3911, a connecting rod 3912, a connecting block 3913, a first opening connecting shaft 3914, a pair of connecting plates 3915 arranged on the left and right, a second opening connecting shaft 3918, and an opening / closing element. The mating block 3911, the connecting rod 3912, and the connecting block 3913 are integrally connected structural components. The cap 392 is connected to the front end of the second end face 150 of the outer tube body. The mating block 3911 is covered by the cap 392, and a through hole is opened in the center of the cap 392. The connecting rod 3912 passes through the through hole of the cap 392. The mating block 3911 is roughly rectangular, and its shape matches the concave part of the concave I-shaped hook 1523. Connecting the mating block 3911 and the concave I-shaped hook 1523 realizes the connection and assembly of the opening / closing device 39 and the push-pull rod 15. The connecting rod 3912 is a slender column with a connecting block 3913 connected to its front end. The connecting block 3913 and all the opening components 391 located at the front end of the connecting block 3913 are confined within the fixing member 3919. The fixing member 3919 has sidewalls on its left and right sides, which restrict the opening components 391 from opening or moving in the left and right directions, but do not restrict the opening components from opening or moving in the up and down directions.

[0056] Connecting plates 3915 are located on both sides of connecting blocks 3913. Connecting blocks 3913 have connecting block holes at their front ends, connecting plates 3915 have first through holes at their rear ends and second through holes at their front ends. The first through holes and connecting block holes are connected by a first wide-opening connecting shaft 3914.

[0057] The opening and closing components include a first opening and closing component 3916 and a second opening and closing component 3917. Each opening and closing component consists of an opening and closing component connecting portion 3920 and an opening and closing component spreading portion 3921 located at the front end of the opening and closing component connecting portion 3920. A first through hole for the opening and closing component connecting portion is provided near the rear end of the opening and closing component connecting portion 3920, and this first through hole connects to the shaft hole of the second through hole of the connecting plate, so that each connecting plate 3915 connects to one opening and closing component. A second through hole for the opening and closing component connecting portion is provided near the front end of the opening and closing component connecting portion, and a fixing through hole is provided on the side wall of the fixing component 3919. The second through hole for the opening and closing component connecting portion and the fixing through hole are connected by a second wide-opening connecting shaft 3918.

[0058] The push-pull rod 152 moves forward, sequentially pushing the mating block 3911, connecting rod 3912, and connecting block 3913 to move in a straight line. The two connecting plates 3915 connected to the shaft hole of the connecting block 3913 also move in a straight line. When the two connecting plates 3915 push the first opening / closing member 3916 and the second opening / closing member 3917 forward, since the first opening / closing member 3916 and the second opening / closing member 3917 are bound between the two side walls of the fixing member 3919 via the second connecting shaft 3918, the first opening / closing member 3916 and the second opening / closing member 3917 are not pushed forward, but instead rotate around the second widening connecting shaft 3918. Specifically, the first opening / closing member 3916 moves upward and the second opening / closing member 3917 moves downward, thus opening the opening / closing members. Similarly, when the push-pull rod 152 moves backward, the opening / closing members close. Through the opening of the opening / closing members, the opening portion 3921 gradually widens the structure.

[0059] The drive device 2 includes a nut 21, a screw 22, and a handle 23. The screw 22 and the handle 23 are sequentially connected to the screw 22 from rear to front. The handle 23 is a handle-like structure extending downward from the screw 22. The screw 22 passes through the upper end 231 of the handle and can move forward or backward relative to the upper end 231 of the handle. The portion of the screw 22 located before the upper end 231 of the handle is enclosed within the connecting tube 12.

[0060] Trigger 14 is connected to the first end 1521 of the push-pull rod, and trigger 14 is arc-shaped. The upper end of trigger 14 is recessed downwards, forming a trigger groove and trigger sidewalls located on the left and right sides of the trigger groove. The trigger sidewalls are respectively provided with trigger first through holes 141, and the first end 1521 of the push-pull rod is provided with a push-pull rod through hole 151. The first end 1521 of the push-pull rod passes through the trigger groove. The trigger first through hole 141 of trigger 14 and the push-pull rod through hole 151 of push-pull rod 152 are connected through the shaft hole of the first connecting shaft 191, enabling the control trigger 14 to drive the push-pull rod 152 to move forward or backward. Figure 2 In order to facilitate the display of the through hole 151 of the push-pull rod, the part of the trigger 14 with the first through hole 141 at the upper end is hidden. Figure 2 The reference numeral 141 in the attached figure refers to the fact that the first through hole 141 of the trigger will be coaxially connected with the through hole 151 of the push-pull rod on the same horizontal line in the actual object.

[0061] The connecting tube 12 is roughly a hollow cylinder with openings at both ends. A lower groove 123 is formed on the lower circumferential surface of the connecting tube 12, and the lateral dimension (left-right direction) of the lower groove 123 is smaller than the diameter of the second end face 122 of the connecting tube. The trigger 14 has a second trigger through hole 142 corresponding to the edge 124 of the connecting tube opening. The second connecting shaft 192 passes through the second trigger through hole 142, and both ends of the second connecting shaft 192 are mounted inside the connecting tube 12, close to the edge 124 of the connecting tube opening. The second connecting shaft 192 is a fixed shaft.

[0062] Link 16 connects trigger 14 and grip 23. Link 16 has a first through hole at its rear end and a second through hole at its front end. Trigger 14 has a third through hole 143 in its middle, and the third through hole 143 and the second through hole are connected via a third connecting shaft 193. The front end of grip 23 is recessed inward to form an inner groove 232. Slide grooves 233 are symmetrically arranged at both ends of the inner groove 232. The two ends of slide groove connecting rod 234 are respectively located within the two slide grooves 233, and the slide groove connecting rod 234 passes through the first through hole of link 16 and connects to link 16. Optionally, a damping device is provided within the slide groove 233; the damping device can be a spring, flexible silicone, or a material with a high coefficient of friction.

[0063] When the trigger 14 is gripped, the second connecting shaft 192 acts as the fulcrum of the lever. The portion of the trigger 14 located at the upper end of the second connecting shaft 192 pushes the push-pull rod 152 forward. The portion of the trigger 14 located at the lower end of the second connecting shaft 192 drives the connecting rod 16 backward via the third connecting shaft 192. The connecting rod 16 further drives the slide rail connecting rod 234 downward along the opening direction of the slide rail 233. When the trigger 14 is released, the above structure can be reset under the action of the damping device.

[0064] In this invention, the push-pull rod 152 can be driven by either the nut 21 or the trigger 14. The nut 21 performs fine-tuning, while the trigger 14 performs rapid operation. These two operating methods can be used in combination or independently.

[0065] The screw 22 includes a first end face 221 at the rear end and a second end face 222 at the front end. The push-pull rod 152 includes a first end face 1521 at the rear end and a second end face 1522 at the front end. In some embodiments, the trigger 14 is first gripped to drive the push-pull rod 152 forward; then the nut 21 is rotated to drive the screw 22 forward until the second end face 222 contacts the first end face 1521 of the push-pull rod. The nut 21 is then rotated to push the push-pull rod 152 forward. The range of motion of the screw 22 pushing the push-pull rod 152 is less than the range of motion of the trigger 14 driving the push-pull rod 152.

[0066] In some embodiments, the pushing device 1 further includes a top post 13, located between the push-pull rod 152 and the screw 22. The top post 13 can be connected to the push-pull rod 152. The top post 13 can be fixedly connected to the push-pull rod 152; for example, the first end 1521 of the push-pull rod has a through hole with an internal thread, and the front end of the top post 13 has an external thread. The external thread of the top post 13 connects to the internal thread of the through hole at the rear end of the push-pull rod 152, thus threading the push-pull rod 152 and the top post 13. Alternatively, the top post 13 can be movably connected to the push-pull rod 152 (e.g., via a ball joint mechanism), and in special circumstances, the connection between the top post 13 and the push-pull rod 152 can be disconnected. The top post 13 can also be unconnected to the push-pull rod 152, with its front end maintaining a certain distance from the first end 1521 of the push-pull rod. The top post 13 can be connected to the screw 22 (e.g., through a ball joint mechanism or by hinge), or it can be not connected to the screw 22, that is, a certain space is released between the rear end of the top post 13 and the second end face 222 of the screw.

[0067] Taking the initial state, where the top post 13 is threadedly connected to the push-pull rod 152 but not connected to the screw 22, but the rear end of the top post 13 is in contact with (or maintains a small distance from) the second end face 222 of the screw, the operation method of this embodiment is introduced as follows:

[0068] ① When the trigger 14 is gripped, the push-pull rod 152 is driven forward. At this time, the component driven at the front end of the push-pull rod 152 reaches the designated position, and the operation ends.

[0069] ② Rotating nut 21 drives screw 22 forward, screw 22 pushes top post 13, and top post 13 further pushes push-pull rod 152 forward. This method is suitable for situations where only a small adjustment is needed to bring the component to the designated position.

[0070] ③ First, grip the trigger 14 to drive the push-pull rod 152 forward. The component driven at the front end of the push-pull rod 152 almost reaches the designated position, but there is still a certain distance. At this time, rotate the nut 21 to drive the screw 22 forward until the screw 22 contacts the top post 13.
