Abstract
Surgical devices such as a device guide for a trajectory frame for image-guided procedures, is configured with first and second elongate and cooperating semi-circular members that together define a longitudinally extending open channel and that can separate along longitudinally extending split lines into discrete first and second elongate semicircular members. The surgical devices with the first and second semi-circular members can include a device guide and dock and lock inserts that are detachably held by dock and lock members to a guide support column that also concurrently holds the device guide during at least part of an image guided procedure.
Claims20
A surgical device guide, comprising first and second elongate semi-circular members that cooperate to define a longitudinally extending open channel and that separate along longitudinally extending split lines into discrete first and second elongate semicircular members.
A trajectory frame assembly, comprising:
- a base having a patient access aperture formed therein, wherein the base is configured to be secured to the body of a patient;
- a yoke movably mounted to the base and rotatable about a roll axis;
- a platform movably mounted to the yoke and rotatable about a pitch axis;
- an elongated device guide support secured to the platform, wherein the guide comprises opposite proximal and distal end portions, wherein the guide comprises a bore therethrough that extends from the proximal end portion to the distal end portion;
- a lock member attached to the device guide support;
- a dock member attached to the device guide support;
- and
- a device guide extending through the device guide support, wherein the device guide has two elongate cooperating members that define a longitudinally extending through-channel when held in the device guide support and that can laterally separate from each other along longitudinally split lines upon removal from the device guide support.
An elongate device guide for a trajectory frame for an image guided surgical procedure, the elongate device guide having first and second longitudinally extending members that form a longitudinally extending open channel when positioned proximate each other and that separate along a pair of diametrically opposed longitudinally extending lines.
A surgical assembly for image guided surgery comprising:
- a device guide support adapted to attach to a trajectory guide frame, the device guide support comprising a cylindrical, longitudinally extending open channel;
- a dock member configured to engage the trajectory guide support;
- a lock member configured to attach to the dock member above the device guide support;
- a removable guide support cap configured to attach to a top of the device guide support under the dock member,
- wherein the lock member and dock member each comprise inserts with cooperating first and second longitudinally extending members that define an open longitudinally extending channel and that can separate from each other when removed from the trajectory guide support.
A trajectory frame assembly with a trajectory frame comprising a tubular device guide support that extends through a platform of the trajectory frame along a Z-direction and includes opposite proximal and distal end portions, wherein the device guide support releasably holds a device guide with a distal end portion that is positioned proximate the patient access aperture, wherein the device guide includes a bore therethrough that is smaller than the device guide support bore and that extends from the proximal end portion to the distal end portion, and wherein the device guide is rigid and has cooperating first and second segments that can be separated along longitudinally extending split lines.
A method of placing an implanting device in a patient, comprising:
- providing a trajectory frame with an elongated guide support releasably holding a device guide;
- guiding placement of the device to a desired interbody location using the trajectory frame;
- inserting the device through the device guide and into the patient at the desired interbody location;
- and then
- slidably removing the device guide out of the guide support and separating the device guide into first and second longitudinally extending members while leaving the implantable device in position in the patient.
