Description

Technical Field

[0001] The present invention particularly relates to an optical fiber injection tool for glaucoma surgery. Background Art

[0002] Glaucoma, characterized by characteristic optic atrophy and visual field loss, is a leading cause of blindness and has a genetic predisposition. While glaucoma cannot generally be prevented, with early detection and appropriate treatment, the vast majority of patients can maintain useful vision throughout their lives.

[0003] At present, medical workers have invented a new leap-forward internal drainage ultra-microsurgery. During the operation, the eyeball is in a closed state, and a small hole is opened at the edge of the cornea to drain the fluid in the eye into the interlayer of the white eyeball, thereby reducing intraocular pressure. Then, through a one-millimeter incision, the optical fiber is passed into the eye to form a 360-degree closed loop, which can prevent the rupture of blood vessels in the eye and bleeding, and effectively treat glaucoma.

[0004] For example, Chinese patent No. 202120394679.2 provides an optical fiber injector for glaucoma surgery. Threads located inside the tube cap and on the outside of the push rod allow the injector to be moved forward and backward to inject the optical fiber. Furthermore, a three-pronged valve allows for electrically clamping the optical fiber. However, existing optical fiber injectors are mostly handheld, making it difficult to precisely and stably control the injection direction and position of the optical fiber. This can lead to deviations in the injection process due to hand shaking. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention proposes an optical fiber injection tool for glaucoma surgery to solve the technical problem raised in the above background technology, that is, most traditional optical fiber injection tools are handheld, which is not convenient for stable and precise control of the injection direction and injection position of the optical fiber, resulting in deviation of the optical fiber injection due to hand shaking during the injection process.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an optical fiber injection tool for glaucoma surgery, comprising:

[0017] The second worm gear is arranged at the hinge point between the electric telescopic rod and the mounting seat, and the second worm is meshed with the second worm gear.

[0018] Furthermore, the mounting shell is provided with an articulated frame and a sliding frame extending along the axial direction of the mounting shell, wherein one end of one group of connecting rods is provided with an articulated seat, and one end of another group of connecting rods is provided with a first push rod, the articulated seat is hinged to the articulated frame, and the first push rod is slidably clamped in the sliding frame along the extension direction of the sliding frame.

[0019] Furthermore, a threaded rod rotatable along its axis is passed through the fixing seat, and the connecting rod is sleeved on the threaded rod and screwed thereto.

[0020] Furthermore, a positioning rod parallel to the axis of the threaded rod is provided on the fixing seat, a positioning hole parallel to the axis of the threaded rod is opened on the connecting rod, and the positioning rod is inserted into the positioning hole.

[0021] Furthermore, a first guide seat is provided on the mounting shell, and a second guide seat is provided inside the mounting shell. Conical through holes are provided on the first guide seat and the second guide seat. The optical fiber passes through the two groups of the conical through holes and extends out through the outlet at the bottom of the mounting shell.

[0022] Furthermore, the injection mechanism includes:

[0023] There are four sets of transmission wheels, each of which is rotatable along its axis within the mounting housing, with each two sets of transmission wheels connected by a set of propulsion belts, and an optical fiber disposed between the two sets of propulsion belts;

[0024] There are two sets of transmission gears, which are coaxially connected to two sets of the transmission wheels respectively, and the two sets of transmission gears are meshed with each other;

[0025] a third worm gear, disposed on one of the transmission wheels and coaxially connected thereto; and

[0026] The third worm is rotatably arranged on the mounting shell along its axis, and the third worm is engaged with the third worm wheel. A hand wheel is provided at one end of the third worm.

[0027] Furthermore, a shearing mechanism for shearing the optical fiber is further provided in the mounting housing, wherein the shearing mechanism comprises two sets of shearing units arranged opposite to each other, and the shearing units comprise:

[0028] A lifting frame is escalably disposed within the mounting shell, a ratchet block connected via a first elastic member is disposed on one side of the lifting frame, and a second push rod is disposed at one end of the lifting frame;

[0030] The shearing knife is slidably arranged in the mounting shell along the axis direction of the third worm, and the optical fiber passes between the two oppositely arranged groups of shearing knives. The shearing knife is provided with an inclined frame, and the second push rod is slidably clamped in the inclined frame.

[0031] Furthermore, a first stop frame is provided on the lifting frame, a second stop frame is provided in the mounting shell, and a second elastic member is provided between the first stop frame and the second stop frame.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. When the injection tool is in use, the base can be fixed to the surgical area through a fixing part, the height of the injection can be adjusted by controlling the extension and retraction of the electric telescopic rod, and the position of the injection can be adjusted by controlling the two sets of connecting rods to slide along their axes at the same time.

[0034] 2. After adjusting the injection position and injection angle, the third worm can be driven to rotate by turning the hand wheel, and one set of transmission wheels can be driven to rotate through cooperation with the third worm gear. During the rotation of one set of transmission wheels, the other set of transmission wheels can be driven to rotate in the opposite direction through cooperation with the transmission gear, and the propulsion belts can be driven to move under the action of the remaining two sets of transmission wheels, and the movement directions of the two sets of propulsion belts are opposite, thereby propelling the optical fiber through friction.

[0035] 3. During the advancement process, the ratchet pushes the ratchet block inward on the lifting frame without causing the lifting frame to move. The first elastic member keeps the ratchet block stuck to the ratchet. After advancement is complete, a certain length of optical fiber can be left outside the outlet. The handwheel is then slightly reversed. The engagement of the ratchet and ratchet block drives the lifting frame upward a certain distance, driving the second push rod to rise. During this rise, the second push rod cooperates with the inclined frame to drive the two sets of shear blades to slide horizontally and close together to cut the optical fiber. This eliminates the need for manual shearing tools to cut the optical fiber, improving the convenience and safety of the injection tool. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0056] Example:

[0057] like Figure 1 、 2 As shown, the present invention provides an optical fiber injection tool for glaucoma surgery, comprising a base 101. A fixing member 102 is disposed at the bottom of base 101, which secures the tool to an operating table for use. A rotatable mounting seat 104 is disposed on base 101. A first adjustment assembly is disposed within base 101 to control the rotation of mounting seat 104 along its axis.

[0058] The first adjustment assembly includes a first worm 103 rotatably disposed along its axis within the base 101. One end of the first worm 103 extends through the base 101 and outward. A first worm wheel 105 is coaxially mounted on the bottom of the mounting base 104, and the first worm 103 meshes with the first worm wheel 105. By rotating the first worm 103, the meshing action of the first worm 103 and the first worm wheel 105 allows the mounting base 104 to rotate along its axis and self-lock.

[0059] like Figure 1 、 3 As shown in Figures 4 and 5, in this embodiment, a hinged electric telescopic rod 201 is provided on the mounting base 104, and a second adjustment component is provided on the mounting base 104 to control the rotation of the electric telescopic rod 201 along the hinge point between the electric telescopic rod 201 and the mounting base 104. A fixed base 203 is provided on the mounting base 104, and the second adjustment component includes a second worm 106 rotatable along its axis and provided on the mounting base 104. A second worm gear 202 is provided at the hinge point between the electric telescopic rod 201 and the mounting base 104, and the second worm 106 is engaged with the second worm gear 202.

[0060] The electric telescopic rod 201 can be controlled to rotate along the hinge point between the electric telescopic rod 201 and the mounting base 104 by rotating the second worm 106 and meshing with the second worm wheel 202, and the position of the electric telescopic rod 201 can be self-locked, thereby adjusting the angle of the fixing base 203. The fixing base 203 can be raised by controlling the electric telescopic rod 201 to extend and retract.

[0061] like Figure 2 、 3As shown in Figures 4 and 5, in this embodiment, two sets of connecting rods 206 are provided on the fixed seat 203. The connecting rods 206 are perpendicular to the axis of the electric telescopic rod 201, and both sets of connecting rods 206 can slide along their axes. The mounting shell 301 is provided with an articulated frame 304 and a sliding frame 303 extending along the axis of the mounting shell 301. One end of one set of connecting rods 206 is provided with an articulated seat 208, and one end of the other set of connecting rods 206 is provided with a first push rod 209. The articulated seat 208 is hinged to the articulated frame 304, and the first push rod 209 is slidably mounted in the sliding frame 303 along the extension direction of the sliding frame 303. A threaded rod 205 rotatable along its axis is passed through the fixed seat 203, and the connecting rod 206 is sleeved on the threaded rod 205 and screwed thereto.

[0062] Rotating one of the threaded rods 205, which is mounted with the first push rod 209, allows the connecting rod 206 to move. Furthermore, since the fixing base 203 is provided with a positioning rod 204 parallel to the axis of the threaded rod 205, and the connecting rod 206 is provided with a positioning hole 207 parallel to the axis of the threaded rod 205, the positioning rod 204 is inserted into the positioning hole 207. During rotation, the threaded rod 205 can only slide along the axis of the positioning rod 204. The first push rod 209 and the sliding frame 303 can then drive the mounting housing 301 to rotate along the axis of the hinged base 208. The mounting housing 301 is equipped with an injection mechanism for injecting the optical fiber. The angle of the mounting housing 301 can be adjusted in multiple directions through the coordination of the first adjustment assembly, the second adjustment assembly, and the rotation of one of the threaded rods 205.

[0063] The mounting shell 301 can also be driven to translate along the axis direction of the threaded rod 205 by rotating the two sets of threaded rods 205 at the same time, and with the cooperation of the electric telescopic rod 201, the height and lateral position of the mounting shell 301 can be adjusted to adjust the position and angle of the injection mechanism in multiple directions, thereby adjusting and fixing the injection position and injection direction of the optical fiber. There is no need to manually hold the injection tool for use, which effectively avoids the shaking of the injection tool due to hand movement and improves the stability of the optical fiber injection.

[0064] like Figure 2 、 8As shown, in this embodiment, a first guide seat 305 is provided on the mounting housing 301, and a second guide seat 306 is provided within the mounting housing 301. Both the first guide seat 305 and the second guide seat 306 have tapered through-holes. The optical fiber passes through the two sets of tapered through-holes and extends outward through an outlet 302 at the bottom of the mounting housing 301. The optical fiber can be inserted into the mounting housing 301 through the tapered through-holes in the first guide seat 305, and the tapered through-holes in the second guide seat 306 guide the movement of the optical fiber within the mounting housing 301. This allows the optical fiber to smoothly pass through the outlet 302 at the bottom of the mounting housing 301 and extend outward, thereby improving the convenience of optical fiber installation.

[0065] like Figure 2 、 6 As shown in Figure 7, in this embodiment, the injection mechanism includes four groups of transmission wheels 401, and the four groups of transmission wheels 401 are rotatably arranged along their axes in the mounting shell 301. Every two groups of transmission wheels 401 are connected by a group of propulsion belts 404, and the optical fiber is arranged between the two groups of propulsion belts 404. Two groups of transmission wheels 401 are provided with coaxial transmission gears 402, and the two groups of transmission gears 402 are meshed with each other. One group of transmission wheels 401 is provided with a third worm gear 407 coaxial therewith, and a rotatable third worm 408 is passed through the mounting shell 301, and the third worm 408 is meshed with the third worm gear 407. A handwheel 403 is provided at one end of the third worm 408.

[0066] The third worm 408 can be driven to rotate by rotating the handwheel 403. During the rotation process, the third worm 408 drives one of the transmission wheels 401 to rotate by meshing with the third worm gear 407. During the rotation process, one of the transmission wheels 401 controls the other transmission wheel 401 to rotate in the opposite direction through the meshing of the two transmission gears 402. During the rotation process, the above two transmission wheels 401 can drive the two propulsion belts 404 to move in opposite directions through the cooperation of the other two transmission wheels 401. The two propulsion belts 404 can propel the optical fiber during the movement.

[0067] like Figure 7 As shown, in this embodiment, the propulsion belts 404 are provided with propulsion ribs 405, each of which is provided with a guide groove 406. The optical fiber is arranged in the space formed by the guide grooves 406 between two adjacent sets of propulsion belts 404. The provision of the propulsion ribs 405 improves the propulsion effect on the optical fiber. The guide grooves 406 guide the optical fiber during propulsion, preventing it from deflecting during propulsion and further improving the stability of the optical fiber during propulsion.

[0068] like Figure 6 、 7As shown, in this embodiment, the mounting housing 301 is provided with the same number of connecting frames 501 as the number of propulsion belts 404. The connecting frames 501 are provided with pressure plates 503 connected via telescopic columns 502. The pressure plates 503 contact the inner side surfaces of the propulsion belts 404, and a third elastic member 504 is provided between the pressure plates 503 and the connecting frames 501. The third elastic member 504 propels the pressure plates 503 along the axis of the telescopic columns 502, thereby slightly moving the propulsion belts 404, ensuring contact between the propulsion belts 404 and the optical fibers, preventing slippage between the optical fibers and the propulsion belts 404, and further improving the stability of the propulsion of the optical fibers.

[0069] like Figure 8 、 9 As shown in Figure 10, in some embodiments, a shearing mechanism for shearing the optical fiber is further provided in the mounting shell 301, and the shearing mechanism includes two groups of shearing units arranged oppositely. The shearing unit includes a lifting frame 602 that can be raised and lowered and is arranged in the mounting shell 301. A ratchet block 604 connected by a first elastic member 603 is provided on one side of the lifting frame 602, and a second push rod 608 is provided at one end of the lifting frame 602. A coaxial ratchet 601 is fixedly provided on the third worm 408, and the ratchet 601 is engaged with the ratchet block 604. A shearing knife 701 that can slide along the axis direction of the third worm 408 is provided in the mounting shell 301, and the optical fiber passes between the two groups of shearing knives 701 arranged oppositely. An inclined frame 702 is provided on the shearing knife 701, and the second push rod 608 is slidably clamped in the inclined frame 702.

[0070] When the hand wheel 403 is turned to drive the third worm 408 to rotate and advance the optical fiber, the inclined surface of the ratchet teeth on the ratchet 601 pushes the ratchet block 604 to move horizontally to compress the first elastic member 603, thereby not driving the lifting frame 602 to move. When it is necessary to cut the optical fiber, the hand wheel 403 can be slightly reversed to drive the ratchet 601 to reverse. During the reversal process, the ratchet 601 can cooperate with the ratchet block 604 to drive the lifting frame 602 to move upward by one end. During the upward movement of the lifting frame 602, the second push rod 608 is lifted. During the movement, the second push rod 608 can drive the shear knife 701 to slide horizontally in cooperation with the inclined frame 702. The two sets of shear knives 701 slide horizontally and close together to cut the optical fiber. There is no need to use other tools to cut the injected optical fiber, which improves the convenience of the injection tool when injecting the optical fiber.

[0071] A first stop 605 is provided on the lifting frame 602, a second stop 606 is provided within the mounting housing 301, and a second elastic member 607 is provided between the first stop 605 and the second stop 606. After the lifting frame 602 is raised to cut the optical fiber, the hand wheel 403 is released, and the lifting frame 602 is reset under the action of the second elastic member 607, thereby returning the two sets of shear blades 701 to their original positions for the next use.

[0072] Specific usage and beneficial effects of the present invention:

[0073] When the injection tool is in use, the base 101 can be fixed to the surgical area through the fixing part 102, and the height of the injection can be adjusted by controlling the extension and retraction of the electric telescopic rod 201. The position of the injection can be adjusted by controlling the two groups of connecting rods 206 to slide along their axes at the same time. The first worm 103 can be rotated to rotate the first worm gear 105, thereby driving the mounting base 104 to rotate along its axis. By rotating the second worm 106, the electric telescopic rod 201 is driven to rotate along the hinge point between it and the mounting base 104 in cooperation with the second worm gear 202, and one group of connecting rods 206 is controlled to slide along its axis to adjust the angle of the injection, thereby facilitating and stably controlling the injection direction and injection position accurately, thereby avoiding deviation of the optical fiber injection due to hand shaking during the injection process.

[0074] After adjusting the push position and the push angle, the third worm 408 can be driven to rotate by turning the hand wheel 403, and one of the groups of transmission wheels 401 can be driven to rotate by cooperating with the third worm gear 407. During the rotation process, one group of transmission wheels 401 drives the other group of transmission wheels 401 to rotate in the opposite direction through the cooperation of the transmission gear 402, and the propulsion belt 404 is driven to move under the action of the remaining two groups of transmission wheels 401, and the movement directions of the two groups of propulsion belts 404 are opposite, so that the optical fiber is propelled by friction.

[0075] During the advancement process, the ratchet wheel 601 pushes the ratchet block 604 inward on the lifting frame 602 without moving the lifting frame 602. The first elastic member 603 acts to keep the ratchet block 604 stuck to the ratchet wheel 601. After the advancement is completed, a certain length of optical fiber can be reserved outside the outlet 302. The handwheel 403 is then slightly reversed. The engagement of the ratchet wheel 601 and the ratchet block 604 drives the lifting frame 602 upward a certain distance, thereby driving the second push rod 608 upward. During the upward process, the second push rod 608 cooperates with the inclined frame 702 to drive the two sets of shear blades 701 to slide horizontally and close together to cut the optical fiber. This eliminates the need for manual shearing tools to cut the optical fiber, improving the convenience and safety of the injection tool.

[0076] The basic principles, main features and advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
