Abstract
A surgical instrument comprising an implant bending device including a mating part such that the implant bending device is interchangeable with a bending module and a cutting module. The bending module having work surfaces engageable with a spinal implant to manipulate the spinal implant to a selected implant configuration. The cutting module is engageable with the spinal implant having the selected implant configuration. Systems, surgical instruments, spinal constructs, implants and methods are disclosed.
Claims14
A surgical instrument comprising:
- an implant bending device including a mating part, a bending module and a cutting module, the mating part defining a socket,
- the bending module being engageable with a spinal implant to bend the spinal implant, the bending module comprising a first shaft, and
- the cutting module being engageable with the spinal implant and configured to cut the spinal implant, the cutting module comprising a second shaft, wherein the cutting module defines a cylindrical passageway for disposal of the spinal implant, the second shaft extending parallel to the cylindrical passageway,
- wherein the first shaft is configured for removable disposal in the socket when the second shaft is spaced apart from the socket to bend the spinal implant, and
- wherein the second shaft is configured for removable disposal in the socket when the first shaft is spaced apart from the socket to cut the spinal implant.
2 more elements
A surgical instrument comprising:
- a housing comprising spaced apart first and second connectors;
- a bending module coupled to the second connector;
- a threaded shaft having a first end coupled to the first connector and an opposite second end coupled to the second connector;
- a non-threaded shaft having a first end coupled to the first connector and an opposite second end coupled to the second connector;
- a carrier comprising a first portion defining a threaded passageway, a second portion defining a non-threaded passageway and an engagement portion positioned between the first portion and the second portion, the threaded shaft extending through the threaded passageway, the non-threaded shaft extending through the non-threaded passageway;
- and
- a spinal rod coupled to the engagement portion,
- wherein rotation of threaded shaft causes the carrier to translate along the shafts to move the spinal rod for engagement with the bending module, and
- wherein the engagement portion includes a shaft having an engagement part for connection with the spinal rod, the shaft of the engagement portion being connected with a first gear, a second gear being disposable with the second portion and the non-threaded shaft, the second gear being engageable with the first gear to actuate rotation of the carrier and the spinal rod.

- a threaded shaft having a first end coupled to the first connector and an opposite second end coupled to the second connector;
- a non-threaded shaft having a first end coupled to the first connector and an opposite second end coupled to the second connector;
- a carrier comprising a first portion defining a threaded passageway, a second portion defining a non-threaded passageway and an engagement portion positioned between the first portion and the second portion, the threaded shaft extending through the threaded passageway, the non-threaded shaft extending through the non-threaded passageway;
- and
- a spinal rod coupled to the engagement portion,
- wherein rotation of threaded shaft causes the carrier to translate along the shafts to move the spinal rod for engagement with the bending module,
- wherein the first connector comprises first and second gears, the first end of the threaded shaft comprising a third gear that meshes with the first gear, the first end of the non-threaded shaft comprising a fourth gear that meshes with the second gear, the surgical instrument comprising a motor configured to power rotation of the second and fourth gears.
