Abstract
A retractor system includes a retractor blade and a handle assembly. The retractor blade includes a base portion, a blade extending from the base portion, and a handle mount affixed to the base portion. The handle assembly includes an attachment portion and a retaining rod. The attachment portion includes a slot configured to receive the handle mount, a first cavity adjoining the slot, a retaining member moveable along the first cavity, and a second cavity adjoining the first cavity. Advancement of the retaining rod through the second cavity and into the first cavity advances the retaining member into the slot and into engagement with the handle mount.
Claims19
A retractor system, comprising:
- a retractor blade comprising a base portion, a blade extending from the base portion, and a handle mount affixed to the base portion;
- and
- a handle assembly comprising a rod and an attachment portion that detachably couples the handle assembly to the handle mount of the retractor blade;
- wherein the attachment portion comprises a slot, a first cavity adjoining the slot, a retaining member moveable along the first cavity, a second cavity adjoining the first cavity, and a spring, in the first cavity, that biases the retaining member away from the slot;
- wherein the slot is sized to permit attachment of the handle assembly to the retractor blade via insertion of the handle mount into the slot of the attachment portion and permit detachment of the handle assembly from the retractor blade via withdrawal of the handle mount from the slot of the attachment portion;
- and
- wherein advancement of the rod through the second cavity and into the first cavity advances the retaining member into a locked position in which the retaining member engages the handle mount in the slot of the attachment portion and prevents withdrawal of the handle mount from the slot of the attachment portion.
A retractor system, comprising:
- a retractor blade comprising a base portion, a blade extending from the base portion, and a handle mount affixed to the base portion;
- and
- a handle assembly comprising an attachment portion detachably coupled to the handle mount of the retractor blade and a rod extending into the attachment portion;
- wherein the attachment portion comprises a slot, a spring, and a retaining member;
- wherein the rod, when advanced into the attachment portion to a locked position, advances the retaining member into a first position in which the retaining member engages the handle mount in the slot of the attachment portion and prevents withdrawal of the handle mount from the slot of the attachment portion;
- and
- wherein the rod, when withdrawn from the attachment portion to an unlocked position, permits the spring to withdraw the retaining member to a second position in which the retaining member disengages the handle mount in the slot of the attachment portion and permits detachment of the attachment portion from the handle mount of the retractor blade.
A retractor system, comprising:
- a retractor blade comprising a base portion, a blade extending from the base portion, and a handle mount affixed to the base portion;
- and
- a handle assembly comprising an attachment portion detachably coupled to the handle mount of the retractor blade and a rod extending into the attachment portion;
- wherein the attachment portion comprises a slot and a retaining member;
- wherein the rod advances the retaining member into a locked position in which the retaining member engages the handle mount of the retractor blade in the slot of the attachment portion and prevents withdrawal of the handle mount of the retractor blade from the slot of the attachment portion;
- and
- wherein the attachment portion further comprises a spring configured to move and disengage the retaining member from the handle mount of the retractor blade as the rod is moved away from the retaining member.
