[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This intelligent, precise, and visual intraocular vascular thrombolysis treatment device first pushes the adjustment knob to the right to separate the limiting strip from the annular limiting seat, then pushes the adjustment knob to rotate, causing the insert to rotate. This, combined with the threaded connection between the insert and the internal threaded ring, causes the collar, connecting strip, and synchronous ring to move forward along the slide groove. Then, through the connecting action of the sliding rod, the C-shaped baffle moves forward synchronously, adjusting the distance between the C-shaped baffle and the end of the injection needle. During the rotation of the insert, the scale on the graduated paper tape passes through the second reading window sequentially, allowing the distance between the C-shaped baffle and the end of the injection needle to be reflected through the reading on the graduated paper tape. This achieves the purpose of facilitating control of the depth of needle insertion into the eyeball. The motor starts, driving the rotating shaft. When the ball bearing slides along the spiral groove, it pushes the tube and insert forward. When the ball bearing slides along the arc groove, the push tube stops moving, causing the injection piston to move forward intermittently, allowing the medication inside the transparent syringe to be injected into the eyeball in batches. During the forward movement of the push tube, the connection between the electric sliding strip, electric sliding sleeve, and conductive wire keeps the LED light and the power supply battery electrically connected. The light emitted by the LED light is reflected by the reflective inclined surface, passes through the light-transmitting slit, and shines onto the volume scale on the surface of the transparent syringe. The reading of the bar light band on the volume scale can be observed through the reading window to understand the amount of medication injected into the eyeball. As the insert rotates and moves forward, the pressure tube squeezes the inclined boss through the contraction section, causing the friction steel plate to bend and deform inward into the receiving tube. This causes the friction steel plate to be pressed against the inner wall of the straight groove, increasing the resistance to the movement of the push tube and reducing its speed, thereby reducing the injection speed of the medication. This achieves the purpose of easily controlling the amount of medication injected into the eyeball. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.
[0019] Please see Figures 1-13The present invention provides a technical solution: an intelligent, precise, and visualized intraocular vascular thrombolysis treatment device, comprising a housing 100, a cover 200 detachably mounted on the front right side of the housing 100, an injection component 300 sandwiched between the housing 100 and the cover 200, an injection depth adjuster 400 slidably connected through the front end of the housing 100, a rotation drive 500 disposed at the rear end of the injection depth adjuster 400, a piston pusher 600 disposed inside the housing 100, and a reading component 700 disposed between the injection component 300 and the piston pusher 600.
[0020] The outer casing 100 includes a grip handle 101. A transition tube 102 is integrally formed at the front end of the grip handle 101. A fixing cover 103 is fixedly installed on the left side of the front end of the transition tube 102. The fixing cover 103 and the covering cover 200 cooperate to form a receiving cavity. The injection component 300 is installed inside the receiving cavity. The injection component 300 is a disposable item and is discarded after injection. A spacer tube 104 is fixedly installed on the inner wall of the transition tube 102. The axis of the spacer tube 104 coincides with the axis of the grip handle 101. An annular cavity is formed between the outer wall of the spacer tube 104 and the inner wall of the transition tube 102. A sliding groove 105 is formed through the circumference of the spacer tube 104. The sliding groove 105 is arranged along the axis of the spacer tube 104. An adjustment window 106 is provided on the right side of the rear end of the grip handle 101. A battery compartment 107 is fixedly installed through the center of the rear end of the grip handle 101. A sealing cover 108 is provided at the rear end of the battery compartment 107. The sealing cover 108 is connected to the rear end of the battery compartment 107 by means of threads or snap-fit, so that the sealing cover 108 can be detachably installed on the rear side of the battery compartment 107, making it convenient to replace the power supply battery 112 inside the battery compartment 107.
[0021] The injection assembly 300 includes a transparent syringe 301. An injection needle 302 is positioned at the front end of the transparent syringe 301. The injection needle 302 is installed at the front end of the transparent syringe 301 via a plug-and-play mechanism, allowing for interchangeability of the needle type. The size of the injection needle 302 is greater than 41g. Since the axial length of the human eye is typically 18-30mm, the injection needle 302 must be at least 20mm long to be inserted behind the limbus into the retinal vessels and fixed to the eyeball. Based on the specific location of the thrombus vessels observed preoperatively, precise positioning is achieved, and the required insertion depth of the injection needle 302 into the eyeball is calculated. The insertion length of the injection needle 302 is then controlled by an injection depth adjuster 400. Finally, the thrombolytic agent is injected through the injection needle 302 into the blood vessel. An injection piston 303 is slidably connected to the rear end of the transparent syringe 301. A rectangular retaining ring 304 is fixedly installed at the rear end of the injection piston 303.
[0022] A reading window 201 is provided through the right side of the cover 200. The transparent syringe 301 has a capacity scale along its length. The capacity scale on the surface of the transparent syringe 301 can be observed through the reading window 201, which makes it easy to observe the scale corresponding to the position of the injection piston 303 inside the transparent syringe 301 during the injection process.
[0023] The left side of the reading window 101 has four mounting slots 202 arranged in a matrix. Each mounting slot 202 has an L-shaped retaining strip 203 slidably connected to it. The end of the L-shaped retaining strip 203 is provided with an inclined chamfer. A spring 204 is fixedly installed between the L-shaped retaining strip 203 and the inner wall of the mounting slot 202. The right side of the fixing cover 103 has four slots 205 arranged in a matrix. The L-shaped retaining strip 203 is elastically engaged in the slots 205 by the spring 204. When the cover 200 is connected to the fixed cover 103, the cover 200 adheres to the surface of the fixed cover 103 from right to left. The edge of the slot 205 presses against the chamfer of the L-shaped clip 203, and the spring 204 is compressed. Then, when the end of the L-shaped clip 203 passes the edge of the slot 205, under the elastic action of the spring 204, the L-shaped clip 203 is engaged in the slot 205, so that the cover 200 and the fixed cover 103 are stably connected together.
[0024] The cover 200 has a disassembly knob 206 rotatably connected to both its top and bottom. A gear 207 is fixedly mounted on the circumference of the disassembly knob 206. A rack plate 208 meshes with the front and rear sides of the gear 207. A push plate 209 is fixedly mounted on one of the opposite ends of each rack plate 208. Two guide grooves 210 are formed inside the cover 200. Each guide groove 210 connects to two mounting grooves 202 at both ends. The rack plate 208 and push plate 209 are slidably connected within the guide grooves 210. When disassembling the cover 200, turning the disassembly knob 206 rotates the gear 207, causing the two rack plates 208 to move in opposite directions. The push plate 209 enters the mounting groove 202 and pushes the two L-shaped retaining strips 203 to move in opposite directions, thus disengaging the L-shaped retaining strips 203 from the retaining grooves 205.
[0025] The injection depth adjustment component 400 includes an insert 401 rotatably connected inside the grip handle 101 and the transition tube 102. The outer diameter of the insert 401 is smaller than the inner diameter of the grip handle 101. An internally threaded ring 402 is fixedly installed on the inner wall of the front end of the grip handle 101. The outer wall of the insert 401 is threaded, and the insert 401 is threaded together. A collar 403 is rotatably connected to the front end of the insert 401. The collar 403 is slidably connected inside the spacer tube 104. Two connecting strips 404 are fixedly installed on the outer wall of the collar 403. The connecting strips 404 are slidably connected through a groove 105. A synchronizing ring 405 is fixedly installed at the end of the connecting strip 404 away from the collar 403. The synchronizing ring 405 is slidably connected between the outer wall of the spacer tube 104 and the inner wall of the transition tube 102. Therefore, when the insert 401 is screwed on, the insert 401 rotates relative to the internal threaded ring 402 and moves relative to the internal threaded ring 402 in the front-back direction. This causes the collar 403, connecting bar 404 and synchronizing ring 405 to move along the length of the slide groove 105.
[0026] A slide rod 406 is fixedly installed on the left side of its front end. The slide rod 406 is slidably connected inside the fixed cover 103. A C-shaped baffle 407 is fixedly installed at the front end of the slide rod 406. When the injection assembly 300 is installed inside the fixed cover 103, the injection needle 302 is inserted into the C-shaped baffle 407 through the notch. Thus, by sliding the slide rod 406 relative to the fixed cover 103, the distance between the C-shaped baffle 407 and the end of the injection needle 302 is adjusted, controlling the length of the injection needle 302 that can be inserted into the eyeball. A graduated paper tape 408 is fixedly installed on the outer wall of the tube 401. The graduated paper tape 408 is spirally fixed on the tube 401. The pitch of the graduated paper tape 408 is equal to the pitch of the thread on the surface of the tube 401. The surface of the graduated paper tape 408 is provided with length graduations. A reading window 409 is provided through the surface of the handle 101. As the insert tube 401 is screwed on, the scale on the surface of the scale paper tape 408 passes through the reading window 409 in sequence, so that the distance the insert tube 401 moves forward can be read, and then the distance the C-shaped baffle 407 moves forward can be read, which reflects the distance between the C-shaped baffle 407 and the end of the injection needle 302.
[0027] The rotation drive component 500 includes an adjustment knob 501 slidably connected to the outside of the battery compartment 107, which supports and guides the adjustment knob 501. A second spring 502 is fixedly installed between the rear side of the adjustment knob 501 and the inner wall of the rear end of the grip handle 101. The elasticity of the second spring 502 causes the adjustment knob 501 to tend to move forward. A fixing tube 506 is fixedly installed on the front side of the adjustment knob 501. The fixing tube 506 is sleeved on the outside of the insert tube 401. Limiting strips 507 are fixedly arranged at the front end of the fixing tube 506. An annular limiting seat 508 is fixedly installed on the inner wall of the grip handle 101, and the limiting strips 507 are inserted into the annular limiting seat 508. Thus, the elasticity of the second spring 502 allows the limiting strips 507 to be inserted into the annular limiting seat 508, inhibiting the rotation of the adjustment knob 501 and the fixing tube 506.
[0028] An insert tube 503 is fixedly mounted on the front side of the adjusting knob 501. A protruding strip 504 is fixedly mounted on the circumferential surface of the insert tube 503. A straight groove 505 is formed on the inner wall of the rear end of the embedded tube 401. The insert tube 503 is inserted into the embedded tube 401, and the protruding strip 504 is slidably connected in the straight groove 505. When adjusting the position of the C-shaped baffle 407, the adjusting knob 501 can be pushed backward first to pull the limiting strip 507 out of the annular limiting seat 508. Then, the adjusting knob 501 can be pushed to rotate. Through the connection between the protruding strip 504 and the straight groove 505, the embedded tube 401 is driven to rotate. During this process, the embedded tube 401 can slide relative to the protruding strip 504. After the adjustment is completed, the adjusting knob 501 is released. Under the elastic action of the second spring 502, the adjusting knob 501 and the fixed tube 506 move forward, and the limiting strip 507 is inserted into the annular limiting seat 508.
[0029] The piston pusher 600 includes a motor 601 fixedly mounted at the front end of the battery compartment 107. A rotating shaft 602 is connected to the front output end of the motor 601. The rotating shaft 602 has spiral grooves 603 arranged in an array along its length. Adjacent spiral grooves 603 are connected by an arc-shaped groove 610, the center of which coincides with the axis of the rotating shaft 602. The connection between the arc-shaped groove 610 and the spiral grooves 603 is an arc-shaped transition. A push tube 604 is sleeved on the outside of the rotating shaft 602. An insert 605 is fixedly mounted at the front end of the push tube 604 and is inserted into the confining ring 304. At least two sliding balls 611 are fixedly mounted on the inner wall of the push tube 604, slidably connected within the spiral grooves 603 and the arc-shaped grooves 610. The spacing between the sliding balls 611 is equal to the array spacing of the spiral grooves 603. Furthermore, when the insert 605 is attached to the surface of the injection piston 303, the ball 611 slides into the arc groove 610.
[0030] An insert 605 is fixedly installed at the front end of the push tube 604. A straight groove 606 is formed on the circumferential surface of the push tube 604. A support ring 607 is fixedly installed on the inner wall of the front end of the spacer tube 104. A receiving tube 608 is fixedly installed on the rear side of the support ring 607. The receiving tube 608 is sleeved on the outside of the push tube 604. A protrusion 609 is fixedly installed on the inner wall of the receiving tube 608. The protrusion 609 is slidably connected in the straight groove 606. Through the cooperation of the protrusion 609 and the straight groove 606, the movement path of the push tube 604 is guided, so that the push tube 604 can only move along its axial direction.
[0031] During the rotation of the shaft 602 driven by the motor 601, when the sliding ball 611 slides along the spiral groove 603, the push tube 604 moves along its axial direction; when the sliding ball 611 slides along the arc groove 610, the push tube 604 remains stationary. Thus, through the spiral groove 603 array design, the push tube 604 moves forward intermittently as the shaft 602 rotates, allowing the drug inside the transparent syringe 301 to be injected in batches, making it easier to determine when to stop the injection and thus control the amount of drug injected.
[0032] A pressure tube 612 is fixedly installed on the inner wall of the embedded tube 401. A contraction section 613 is provided on the inner wall of the front end of the pressure tube 612, and the inner diameter of the contraction section 613 gradually decreases from front to back. The inner diameter of the pressure tube 612 is equal to the outer diameter of the receiving tube 608. A friction steel plate 614 is provided at the front end of the receiving tube 608. Specifically, a rectangular mounting window is provided on the receiving tube 608, and the friction steel plate 614 is installed on the inner wall of the rectangular mounting window. An inclined boss 615 is fixedly installed at the rear end of the friction steel plate 614, and the inclined boss 615 fits against the contraction section 613. During the adjustment of the position of the C-shaped baffle 407, the insert tube 401 rotates and moves forward. The pressure tube 612 is pressed against the surface of the inclined boss 615 through the contraction part 613, causing the friction steel plate 614 to bend and deform towards the inside of the receiving tube 608. The rear end of the friction steel plate 614 is pressed against the inner wall of the straight groove 606, increasing the moving resistance of the push tube 604, thereby reducing the moving speed of the push tube 604 and the insert 605.
[0033] Motor 601 is electrically connected to a power supply battery 112, which is inserted into the battery compartment 107. Finger ring 109 is fixedly installed on the left side of both the grip handle 101 and the transition tube 102, and finger ring 110 is fixedly installed on the right side of the grip handle 101. A control button 111 is located on the left side of the grip handle 101, and the control button 111 is electrically connected to the motor 601. The motor 601 is started and stopped by the control button 111. The finger rings 109 and 110 allow for one-handed gripping of the grip handle 101, with extra fingers available to press the control button 111.
[0034] The reading assembly 700 includes an LED light 701 disposed in the insert 605. The LED light 701 is electrically connected to a power-connecting slider 702. The power-connecting slider 702 is fixedly installed at the bottom of the push tube 604. A power-connecting sleeve 703 is embedded in the inner wall of the receiving tube 608. The power-connecting slider 702 is slidably connected in the power-connecting sleeve 703. The rear end of the power-connecting sleeve 703 is electrically connected to the power supply battery 112 through a conductive wire 704. Thus, as the push tube 604 moves along its length, the LED light 701 is always electrically connected to the power supply battery 112 through the connection of the power-connecting slider 702, the power-connecting sleeve 703, and the conductive wire 704. A light guide groove 705 is provided at the center of the rear side of the injection piston 303. A reflective inclined surface 706 is provided on the inner wall of the front side of the light guide groove 705. A light transmission slit 707 is provided on the circumferential surface of the injection piston 303, which is connected to the light guide groove 705. The right-view projection of the light transmission slit 707 is located on the reflective inclined surface 706. Thus, the light irradiated by the LED lamp 701 is reflected by the reflective inclined surface 706 and can be emitted from the light transmission slit 707, forming a strip of light on the surface of the transparent injection cylinder 301. Specifically, the strip of light is located on the volume scale of the transparent injection cylinder 301, and as the injection piston 303 slides inside the transparent injection cylinder 301, the strip of light moves synchronously along the volume scale, making it easy to observe the amount of medicine injected into the eyeball during the injection process.
[0035] Working principle: The transparent syringe 301 is embedded inside the fixed cover 103, the injection needle 302 is inserted into the C-shaped baffle 407, the cover 200 is attached to the surface of the fixed cover 103, and the L-shaped clip 203 is inserted into the slot 205, so that the cover 200 is stably connected to the fixed cover 103. First, push the adjustment knob 501 to the right to separate the limiting strip 507 from the annular limiting seat 508. Then, push the adjustment knob 501 to rotate, causing the insert tube 401 to rotate. This, combined with the threaded connection between the insert tube 401 and the internal threaded ring 402, causes the collar 403, connecting strip 404, and synchronous ring 405 to move forward along the slide groove 105. Then, through the connection of the slide rod 406, the C-shaped baffle 407 moves forward synchronously, adjusting the distance between the C-shaped baffle 407 and the end of the injection needle 302. During the rotation of the insert tube 401, the scale on the scale paper tape 408 passes through the reading window 409 in sequence. Thus, the distance between the C-shaped baffle 407 and the end of the injection needle 302 can be reflected by the reading on the scale paper tape 408. Then, loosen the adjustment knob 501. Under the elastic action of the second spring 502, the adjustment knob 501 and the fixing tube 506 move forward, and the limiting strip 507 is inserted into the annular limiting seat 508 to suppress the rotation of the adjustment knob 501.
[0036] By inserting the index and little fingers into the two rings 109 and the thumb into the ring 110, after the injection needle 302 is inserted into the eyeball, the control button 111 can be pressed with the middle finger to start the motor 601, which drives the rotating shaft 602 to rotate. When the slider 611 slides along the spiral groove 603, it pushes the tube 604 and the insert 605 forward. When the slider 611 slides along the arc groove 610, it pushes the tube 604 to stop moving, thereby driving the injection piston 303 to move forward intermittently, so that the medicine inside the transparent injection cylinder 301 is injected into the eyeball in batches. During the forward movement of the push tube 604, the LED light 701 and the power supply battery 112 are kept electrically connected through the connection of the electric sliding bar 702, the electric sliding sleeve 703 and the conductive wire 704. The light emitted by the LED light 701 is reflected by the reflective inclined surface 706, passes through the light-transmitting slit 707 and shines on the capacity scale on the surface of the transparent syringe 301. The reading of the strip light on the capacity scale can be observed through the reading window 201 to understand the amount of medicine injected into the eyeball.
[0037] As the insert tube 401 rotates and moves forward, the pressure tube 612 squeezes the inclined boss 615 through the contraction part 613, causing the friction steel plate 614 to bend and deform into the receiving tube 608, thereby squeezing the friction steel plate 614 onto the inner wall of the straight groove 606, increasing the moving resistance of the push tube 604, reducing the moving speed of the push tube 604, and thus reducing the injection speed of the drug.
