Abstract
A retractor may include a proximal portion and a distal portion opposite the proximal portion. The distal portion may include first and second blade retractors each having a blade receptacle defined in a first end of a body. The blade receptacle has an opening that narrows to a seat for receiving a blade head, the seat defining a shape that reduces translation, rotation, and/or angulation of the blade head.
Claims19
A retractor comprising:
- a proximal portion having a rack and pinion mechanism in connection with a first cabin and a second cabin such that the first and second cabins are independently retractable along the rack, the rack having a first adaptor on a first end and a second adaptor on a second end, the first and second adaptors for selectively connecting the rack to a table-mounted surgical arm;
- a distal portion opposite the proximal portion, the distal portion connected to the proximal portion through a first arm in connection with the first cabin and a second arm in connection with the second cabin, the distal portion having a first blade engagement in connection with the first arm and a second blade engagement in connection with the second arm, wherein the first and second blade engagements each comprise:
- a receiving body in connection with the first arm or second arm, respectively,
- a receptacle defined in a first end of the receiving body,
- the receptacle having an hourglass shape for receiving a blade head,
- a latch for covering a portion of the receptacle upon receipt of the blade head,
- an adaptor at a second end of the receiving body, the adaptor for selectively connecting the distal portion to a table-mounted surgical arm,
- a release latch for retracting the latch, and
- an angulation knob adjacent to the adaptor at the second end of the receiving body, the angulation knob for rotating the receiving body.

- a distal portion opposite the proximal portion, the distal portion comprising:
- a first blade engagement having a blade receptacle defined in a first end of a body of the first blade engagement, the blade receptacle having a lateral opening that narrows to a seat for receiving a shaped blade head, the seat comprising an upper conical portion, a lower conical portion connected to the upper conical portion by a planar and/or cylindrical side wall;
- and
