Abstract
An insertion instrument for inserting an implant includes an elongated main body having a proximal handle and a distal portion that selectively couples to the implant. A wing actuation tool is slidably engaged in a central passage of the elongated main body to fix the implant to the elongated main body. The wing actuation tool temporarily attaches to the implant allowing for deployment and retraction of wings of the implant during surgery. Longitudinal translation of the wing actuation tool deploys an actuation plunger of the implant.
Claims20
An insertion instrument for inserting a spinal implant into a patient, comprising:
- a handle;
- an elongated main body extending distally from the handle;
- a proximal drive shaft receiving the elongated main body therein;
- a distal hex nut driver receiving the proximal drive shaft and the elongated main body therein, the distal hex nut driver being movable about the proximal drive shaft;
- and
- a plunger comprising a plunger knob and a plunger shaft,
- wherein the plunger knob is disposed proximally to the handle, the plunger shaft extending distally therefrom and through a lumen of the handle and the elongated main body,
- wherein the plunger shaft comprises a concentric flange disposed within the lumen of the handle.
A spinal surgical system, comprising:
- an insertion instrument and a spinal implant, the insertion instrument comprising:
- a handle defining a lumen and having an elongated main body extending distally therefrom;
- a proximal drive shaft receiving the elongated main body therein;
- a distal hex nut driver receiving the proximal drive shaft and the elongated main body therein, the distal hex nut driver being movable about the proximal drive shaft;
- and
- an actuation tool comprising:
- a plunger knob having a plunger shaft extending distally therefrom and through the lumen of the handle and the elongated main body;
- a concentric flange disposed at the plunger shaft and within the lumen of the handle;
- and
- a coupling tip configured to couple to the spinal implant;
- and
- the spinal implant comprising:
- an elongated body defining a proximal internal recess for receiving the coupling tip of the insertion instrument;
- and
- a distal anchor comprising one or more deployable blades,
- wherein translation of the actuation tool when coupled to the spinal implant actuates the distal anchor.
A method of instructing use of an insertion instrument to insert a spinal implant into a patient, the method comprising:
- providing the insertion instrument and the spinal implant, the insertion instrument comprising:
- a handle having an elongated main body extending distally therefrom;
- a proximal drive shaft receiving the elongated main body therein;
- a distal hex nut driver receiving the proximal drive shaft and the elongated main body therein, the distal hex nut driver being movable about the proximal drive shaft;
- and
- a plunger extending through the handle and the elongated main body, the plunger comprising a plunger shaft having a concentric flange disposed thereon;
- and
- the spinal implant comprising:
- an elongated body configured to receive a portion of the plunger;
- and
- a distal anchor including one or more deployable blades;
- instructing insertion of the spinal implant into the patient;
- and
- instructing separation of the spinal implant from the insertion instrument.
