Abstract
A device is described for marking a path on a skin surface for inserting an epidural needle into an epidural space. The device includes a first arm having one or more holes spaced apart along the length of the first arm. A pin is attached at the proximal end of the first arm. A second arm has a proximal end attached to the pin allowing the first and second arms to rotate about the pin to adjust an angle separating the first and second arms. The second arm has one or more holes spaced apart along the length of the second arm. The holes on the first and second arms provide locations for marking the path on the skin surface to insert the epidural needle.
Claims20
A device for marking a path on a skin surface for inserting an epidural needle into an epidural space, the device comprising:
- a first arm having a length extending between a proximal end and a distal end, and one or more holes spaced apart along the length of the first arm;
- a pin attached at the proximal end of the first arm;
- and
- a second arm having a proximal end attached to the pin allowing the first and second arms to rotate about the pin to adjust an angle separating the first and second arms, and further having a length extending from the proximal end to a distal end, and one or more holes spaced apart along the length of the second arm;
- wherein the one or more holes on the first and second arms provide locations for marking the path on the skin surface to insert the epidural needle.
A kit for marking a path on a skin surface for inserting an epidural needle into an epidural space, the kit comprising:
- a writing instrument;
- and
- a device comprising:
- a first arm having a length extending between a proximal end and a distal end, and one or more holes spaced apart along the length of the first arm;
- a pin attached at the proximal end of the first arm;
- and
- a second arm having a proximal end attached to the pin allowing the first and second arms to rotate about the pin to adjust an angle separating the first and second arms, and further having a length extending from the proximal end to a distal end, and one or more holes spaced apart along the length of the second arm;
- wherein the one or more holes on the first and second arms provide locations for using the writing instrument to mark the path on the skin surface to insert the epidural needle.
A method of using a device to prepare a patient for implantation of a lead for spinal cord stimulation, the method comprising:
- positioning the device over a target location for implanting the lead;
- adjusting an angle separating first and second arms of the device to define a path for inserting an epidural needle to reach an epidural space of the target location;
- and
- inserting a writing instrument into one or more holes on the first and second arms of the device to mark the path on a skin surface of the patient.
