Abstract
Systems, devices and methods related to retractor systems that retract tissue to allow access to a surgical site are described. The retractor systems can include a first rotatable arm attachable to a first blade, a second rotatable arm attachable to a second blade and a third linearly translatable arm attachable to a third blade. An attachment mechanism that is attachable to a fourth blade can be removably coupled to a mount on the frame. The retractors systems can also include two blade systems whereby when the retractor is in a closed configuration, the two blades form an oval opening.
Claims20
A surgical system comprising:
- a retractor system comprising a first retractor blade, a second retractor blade, and a third retractor blade, wherein the first retractor blade comprises an inner wall that forms a part of a channel that extends a length of the first retractor blade,
- a shim device attached to the first retractor blade, wherein the shim device comprises a proximal portion and a distal portion with the distal portion of the shim device being tapered to engage a portion of a vertebral member,
- wherein the shim device further comprises a first opening and a second opening, and the first retractor blade comprises a latch mechanism configured to fit within the first opening and the second opening, wherein when the latch mechanism is in the first opening the shim device is in a retracted position and wherein when the latch mechanism is in the second opening the shim device is in an extended position, and
- wherein the first retractor blade further comprises a first pair of locking tabs configured to prevent the shim device from moving proximally once the shim device has been slid beyond the first pair of locking tabs.
A surgical system comprising:
- a retractor system comprising a first retractor blade, a second retractor blade, and a third retractor blade;
- and
- a shim device attached to the first retractor blade, wherein the shim device comprises a proximal portion and a distal portion, wherein the shim device is irremovable from the first retractor blade,
- wherein the shim device further comprises a first opening and a second opening, and the first retractor blade comprises a latch mechanism configured to fit within the first opening and the second opening, wherein when the latch mechanism is in the first opening the shim device is in a retracted position and wherein when the latch mechanism is in the second opening the shim device is in an extended position, and
- wherein the first retractor blade further comprises a first pair of locking tabs configured to prevent the shim device from moving proximally once the shim device has been slid beyond the first pair of locking tabs.
