[0004] While this intraocular lens infusion and positioning device allows for the completion of both operations using the same device without requiring device replacement during surgery, it presents a challenge in controlling the injection of surgical fluid. Therefore, improvements to the device are necessary. Utility Model Content

[0005] The purpose of this invention is to provide an intraocular lens infusion and positioning device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intraocular lens infusion and adjustment device, comprising a bottom injection cylinder, wherein an adjustment mechanism is fixedly connected to the top of the bottom injection cylinder, and an infusion mechanism is fixedly connected inside the adjustment mechanism;

[0007] The injection mechanism includes a support ring disposed at the top of the bottom injection cylinder. A T-shaped arc block is disposed on the surface of the support ring. A self-locking electric actuator is fixedly connected to the top of the T-shaped arc block. A support block is fixedly connected to the surface of the self-locking electric actuator.

A scale block is fixedly connected to the top of the T-shaped arc block.

[0008] Preferably, a through hole is formed inside the support block, and the surface of the self-locking electric actuator passes through the through hole inside the support block, so that the self-locking electric actuator can move within the limited position of the through hole.

[0009] Preferably, a slot is formed on one side of the bottom of the T-shaped arc block, and the surface of the block matches the inside of the slot.

[0010] Preferably, the adjusting mechanism includes a lower hollow circular plate, which is fixedly connected to the top of the bottom injection cylinder. A conical cylinder is fixedly connected inside the top of the bottom injection cylinder. Support rods are fixedly connected to the four ends of the lower hollow circular plate. An upper hollow circular plate is fixedly connected to the top of the support rods. A lower telescopic tube is fixedly connected to the top of the lower hollow circular plate. A connecting rod is fixedly connected to the middle of the bottom of the cross ring. A conical block is fixedly connected to the bottom of the connecting rod.

[0012] Preferably, a conical hole is formed inside the conical cylinder, and the surface of the conical block is slidably connected to the inside of the conical hole, which facilitates the control of the injected liquid using the conical block and the conical hole.

[0013] Compared with the prior art, this utility model provides an intraocular lens infusion positioner with the following advantages:

[0014] 1. This artificial lens infusion positioner, through its infusion mechanism, retracts the upper telescopic tube, causing the cross-shaped ring to move. This, in turn, moves the connecting rod and conical block at its bottom upward, allowing the conical block to leave the surface of the conical cylinder. The conical block stops when the scale block on the support ring moves to the groove below the T-shaped arc block. This allows the surgical fluid to flow from inside the conical cylinder to the injection tube on the bottom injection cylinder, enabling control of the outflow from the injection tube. The operation is convenient, quick, and easy to control the injection of surgical fluid.

[0015] 2. This intraocular lens infusion positioner, through an adjustment mechanism, uses a self-locking electric actuator to move a T-shaped arc block, which in turn moves a scale block to a designated scale position on the scale surface and achieves self-locking. This allows for changing the stopping point of the T-shaped arc block and the scale block, thereby controlling the injection speed of the surgical fluid. Attached Figure Description

[0025] This utility model provides the following technical solution:

[0026] Example 1

[0027] Combination Figures 2 to 5 An artificial lens infusion and adjustment device includes a bottom injection cylinder 1, an adjustment mechanism 3 is fixedly connected to the top of the bottom injection cylinder 1, and an infusion mechanism 2 is fixedly connected inside the adjustment mechanism 3.

[0028] The injection mechanism 2 includes a support ring 21, which is located at the top of the bottom injection cylinder 1. A T-shaped arc block 22 is provided on the surface of the support ring 21. A self-locking electric actuator 23 is fixedly connected to the top of the T-shaped arc block 22. A support block 231 is fixedly connected to the surface of the self-locking electric actuator 23. A cross ring 24 is fixedly connected inside the support ring 21. An upper telescopic tube 25 is fixedly connected to the top of the support ring 21. An upper injection cylinder 26 is provided at the top of the upper telescopic tube 25. A stop block 221 is fixedly connected to the left side of the support ring 21. A hollow arc strip 27 is provided on one side of the support ring 21. A scale 29 is fixedly connected to the surface of the hollow arc strip 27. A scale block 28 is fixedly connected to the top of the T-shaped arc block 22. A through hole is opened inside the support block 231. The surface of the self-locking electric actuator 23 passes through the through hole opened inside the support block 231.

[0029] Furthermore, a slot is provided on one side of the bottom of the T-shaped arc block 22, and the surface of the stop block 221 matches the inside of the slot. The upper telescopic tube 25 retracts and drives the cross ring 24 to move, thereby driving the connecting rod 34 and the conical block 35 at its bottom end to move upward, so that the conical block 35 leaves the surface of the conical cylinder 32 until the scale block 28 on the support ring 21 moves to the slot below the T-shaped arc block 22 and stops. This allows the surgical fluid to flow out from the inside of the conical cylinder 32 to the injection tube on the bottom injection cylinder 1, thus enabling the outflow control operation of the injection tube. The operation is convenient and quick, and it is easy to control the injection of surgical fluid.

[0030] Example 2

[0031] See Figure 1-5Furthermore, based on Embodiment 1, the adjustment mechanism 3 further includes a lower hollow circular plate 31, which is fixedly connected to the top of the bottom injection cylinder 1. A conical cylinder 32 is fixedly connected inside the top of the bottom injection cylinder 1. Support rods 33 are fixedly connected to the four ends of the lower hollow circular plate 31. An upper hollow circular plate 37 is fixedly connected to the top of the support rods 33. A lower telescopic tube 38 is fixedly connected to the top of the lower hollow circular plate 31. A connecting rod 34 is fixedly connected to the middle of the bottom of the cross ring 24. A conical block 35 is fixedly connected to the bottom of the connecting rod 34. A spring 36 is fixedly connected between the top of the support ring 21 and the bottom of the upper hollow circular plate 37. The top of the upper hollow circular plate 37 is fixedly connected to the bottom of the upper injection cylinder 26. The bottom of the upper hollow circular plate 37 is fixedly connected to the top of the upper telescopic tube 25. The top of the lower telescopic tube 38 is fixedly connected to the bottom of the support ring 21. Sliding holes are opened inside the four ends of the support ring 21. The surface of the support rod 33 is slidably connected to the sliding holes.

[0032] Furthermore, a conical hole is opened inside the conical cylinder 32, and the surface of the conical block 35 is slidably connected to the inside of the conical hole. The self-locking electric push rod 23 drives the T-shaped arc block 22 to move, thereby driving the scale block 28 to move to the designated scale position on the surface of the scale ruler 29 and achieving self-locking. This allows the T-shaped arc block 22 and the scale block 28 to stop, thereby achieving control of the injection speed of the surgical fluid.

[0033] In actual operation, when this device is used, during the intraocular lens infusion operation, an injection tube is set at the bottom of the bottom injection cylinder 1. When surgical fluid needs to be infused, the surgical fluid is injected from inside the upper injection cylinder 26. At this time, the support ring 21 is moved upward, which in turn causes the upper telescopic tube 25 to retract and the cross ring 24 to move, thereby causing the connecting rod 34 and the conical block 35 at its bottom end to move upward, so that the conical block 35 leaves the surface of the conical cylinder 32 until the scale block 28 on the support ring 21 moves to the slot below the T-shaped arc block 22 and stops. This allows the surgical fluid to flow out from inside the conical cylinder 32 to the injection tube on the bottom injection cylinder 1, thus enabling the outflow operation of the injection tube. The operation is convenient and quick, and the injection of surgical fluid is easy to control.

[0034] Furthermore, when injecting surgical fluid, if the injection speed needs to be controlled, it is only necessary to control the size of the opening between the conical cylinder 32 and the conical block 35. Then, the self-locking electric actuator 23 drives the T-shaped arc block 22 to move, thereby driving the scale block 28 to move to the designated scale position on the surface of the scale 29 and achieving self-locking. This allows the T-shaped arc block 22 and the scale block 28 to stop, thereby achieving control of the injection speed of the surgical fluid.
