A sternal elevator apparatus is disclosed. The sternal elevator may include a panel, a support beam traversing the panel, and a post coupled to a proximal end of the panel. The apparatus may also include an indicator handle coupled to the sternal elevator, an actuator drive pivotably coupled to the indicator handle, and a housing movably coupled to the actuator drive. The sternal elevator apparatus may have an actuator drive incorporating a linear rack. The housing further may include a cylindrical gear where the cylindrical gear is engaged with the linear rack.
Claims7
An assembly comprising:
- a handle portion;
- a fixed lifting member directly coupled to a first portion of the handle portion, the fixed lifting member configured to be inserted into a first portion of sub-xiphoid incision of a patient by a user;
- a rack housing coupled to a second portion of the handle portion, the rack housing having a receiving slot that extends through the rack housing along a slot axis from a first end of the rack housing to a second end of the rack housing, and wherein a cylinder gear is movably coupled to the rack housing, wherein the handle portion does not rotate relative to the rack housing;
- a support member that extends from a first end to a second end along a support member axis, wherein a portion of the support member is slidably disposed within the receiving slot, and wherein the cylinder gear operatively engages a portion of the first portion of the support member to displace the support member relative to the rack housing;
- a paddle member pivotably coupled to a first portion of the support member, wherein the paddle member pivots about a pivot axis, wherein the paddle member extends from a first end to a second end along a paddle axis, and wherein the pivot axis extends transversely through an intermediate portion of the paddle, wherein the paddle member is configured to be inserted into a second portion of sub-xiphoid incision of a patient by a user such that a surface of the paddle member is contact with a portion of the patient's inner organs to create space within the sub-xiphoid incision when the paddle member is displaced in a first direction.
