Intraocular implant delivery device

An intraocular implant delivery device, comprising a housing, a main control pull rod assembly, a slider assembly, a striking assembly, a retracting needle turntable, and a push needle assembly, the main control pull rod assembly, the slider assembly, the striking assembly, and the retracting needle turntable being arranged in the housing, a through hole being provided at a distal end of the housing, a push needle of the push needle assembly extending through the through hole to an outer side of the housing, and the main control pull rod assembly, the slider assembly, and the striking assembly being each provided with an energy source capable of selectively releasing energy,

• wherein the main control pull rod assembly is actuated by an operator through a button arranged on the housing to enable the energy source to drive the main control pull rod assembly to move in an axial direction;
• wherein the main control pull rod assembly comprises a main control pull rod and a first spring, the slider assembly is adjacent to the main control pull rod in a longitudinal direction, and a plurality of protrusions are provided on a side surface of the main control pull rod facing the slider assembly;
• when the button is pressed and the main control pull rod moves axially, the protrusions is configured to push the slider assembly to move away from the button in the longitudinal direction;
• when the protrusions move away from the slider assembly with the main control pull rod, the energy source pushes the slider assembly to move close to the button to an initial position in the longitudinal direction;
• wherein the retracting needle turntable is arranged on a distal side of the slider assembly, a plurality of limit steps are provided on a side surface of the retracting needle turntable facing the push needle assembly, and a driving member for driving the retracting needle turntable to rotate is provided on the slider assembly;
• when the slider assembly moves away from the button in the longitudinal direction, the driving member drives the retracting needle turntable to rotate an angle corresponding to one step to enable the push needle of the push needle assembly to retract one step towards a proximal end;
• wherein the striking assembly is arranged on a side of a proximal end of the slider assembly, when the slider assembly is in an initial position, the energy source connected to the striking assembly is in an energy storage state, and when the slider assembly moves away from the button in the longitudinal direction, the striking assembly moves along a guide curved surface of the slider assembly towards the distal end under the push of the energy source to strike the push needle assembly;
• and
• wherein the push needle assembly is arranged on a side of a distal end of the retracting needle turntable, at least one implant is accommodated inside the push needle, and an elastic claw is provided at a distal end of the push needle;
• when the push needle restricts towards the proximal end, the elastic claw opens when passing by the implant to enable the elastic claw to move from a head of the implant to a tail of the implant, and when the striking assembly strikes the push needle assembly, the push needle assembly drives the push needle to move towards a distal end of the housing, to push the implant to an implantation site of a patient.
