Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an ICL implantation position adjuster. Background Art

[0002] In ophthalmic surgery, especially in the ICL (implantable collamer lens) implantation surgery, it is a safe and high-end myopia correction solution. Different from laser and other surgeries that cut corneal tissue, it does not cut the cornea. Instead, it implants the lens into the eye through a minimally invasive surgery, causing no damage to the cornea. After correction, the vision is clearer, which is a new trend in myopia correction technology.

[0003] Existing ICL implantation surgical instruments often have problems such as complex operation and low positioning accuracy during the implantation process. This not only increases the surgical difficulty but also may affect the surgical effect and the patient's visual experience.

[0004] In view of the above problems, the present utility model document proposes an ICL implantation position adjuster. Summary of the Utility Model

[0005] The purpose of the present utility model is to solve the problems of complex operation and low positioning accuracy in the prior art, which not only increase the surgical difficulty but also may affect the surgical effect and the patient's visual experience, and to propose an ICL implantation position adjuster.

[0006] To achieve the above purpose, the present utility model adopts the following technical scheme:

[0007] An ICL implantation position adjuster includes a handle. One side of the handle is fixedly connected with a guide rail. A slider is slidably connected in the guide rail. One side of the slider is fixedly connected with a fixed block. An implantation needle is installed on one side of the fixed block. One side of the slider is fixedly connected with a fixed rod.

[0008] One side of the fixed block is rotatably connected with a rotating seat. One side of the rotating seat is fixedly connected with a fixed ring. The implantation needle is fixedly connected in the fixed ring.

[0009] An adjusting component is arranged inside the handle, and the adjusting component is used to adjust the position of the implantation needle.

[0010] In a possible design, the adjusting component includes a bidirectional screw rod. The bidirectional screw rod is rotatably connected inside the handle. A guide block is fixedly connected inside the handle. Two threaded blocks are slidably connected in the guide block. Both of the threaded blocks are threadedly connected with the bidirectional screw rod. One side of each threaded block is fixedly connected with a clamping block. The two clamping blocks are respectively located on both sides of the fixed rod.

[0011] In a possible design, a lead screw is threadedly connected to one side of the fixed block, and a limit block is rotatably connected to one end of the lead screw, and the limit block contacts the rotating seat.

[0012] In a possible design, handles are fixedly connected to both ends of the bidirectional screw.

[0013] In a possible design, arc-shaped grooves are provided on the opposite sides of the two clamping blocks, and anti-slip pads are provided in the arc-shaped grooves.

[0014] In a possible design, anti-slip textures are provided on the circumference of the handle.

[0015] In this application, during the operation, the doctor first adjusts the position and angle of the implanting needle according to the surgical needs. By rotating the bidirectional screw, the two threaded blocks will move in opposite directions, thereby driving the clamping blocks to move. The clamping blocks fix the position of the slider through the clamping fixing rod, and further fix the position of the implanting needle. When the angle of the implanting needle needs to be adjusted, the limit block can be pushed to contact and fix its position with the rotating seat by rotating the lead screw, and then the rotating seat is rotated to adjust the angle of the implanting needle. After the position and angle are adjusted, the doctor can accurately implant the implanting needle into the patient's eye through the handle to complete the ICL implanting operation.

[0016] Beneficial effects:

[0017] In the present utility model, for the ICL implanting position adjuster, the fixed block and the rotating seat are rotatably connected through the cooperation of the lead screw and the limit block, ensuring the stability of the implanting needle during rotation. At the same time, the design of the arc-shaped grooves and anti-slip pads on the clamping blocks further enhances the clamping stability and anti-slip performance;

[0018] In the present utility model, for the ICL implanting position adjuster, through the cooperation of the bidirectional screw and the threaded block in the adjusting assembly, the clamping position of the clamping block on the fixing rod can be controlled, and further the precise adjustment of the position of the implanting needle can be achieved.
