Stylet Feeder For Surgical Tool
A stylet feeder for connection to a surgical tool includes a base for attaching to a surgical tool, the base having a platform and a skirt extending distally from the platform. The stylet feeder also includes an extension protruding proximally from the platform of the base, the extension having a proximal end housing a pawl, the pawl having a distal end with a threaded portion. The base and the extension define a passage extending in a proximal-distal direction such that the stylet feeder is cannulated for accepting a stylet therethrough.
1 . A stylet feeder for connection to a surgical tool, the stylet feeder comprising:
a base for attaching to the surgical tool, the base having a platform and a skirt extending distally from the platform and defining a slit passing between opposing ends of the skirt when the stylet feeder is in a resting configuration,
wherein the base defines a passage extending in a proximal-distal direction such that the stylet feeder is cannulated for accepting a stylet therethrough.
2 . The stylet feeder of claim 1 , wherein each of the opposing ends of the skirt include a lateral protrusion extending outward from the skirt.
3 . The stylet feeder of claim 2 , wherein each of the lateral protrusions define an aperture therethrough for connection with a fastener.
4 . The stylet feeder of claim 3 , further comprising a fastener disposed through the apertures of the lateral protrusions and configured to force the lateral protrusions toward each other and into a clamped configuration.
5 . The stylet feeder of claim 1 , wherein the skirt and the platform define a cavity into which a proximal end of a surgical tool can be disposed and secured.
6 . The stylet feeder of claim 1 , wherein the slit passes through a portion of the platform.
7 . The stylet feeder of claim 1 , further comprising an extension protruding proximally from the platform of the base, the extension having a proximal end housing a pawl, the pawl having a distal end with a threaded portion.
8 . The stylet feeder of claim 7 , wherein the extension defines a window passing laterally therethrough.
9 . The stylet feeder of claim 7 , wherein the pawl is pivotable such that the distal end can move toward and away from the passage through the extension.
10 . The stylet feeder of claim 7 , wherein the threaded portion of the pawl is a left-handed thread.
11 . The stylet feeder of claim 7 , wherein the extension further includes a second pawl having a distal end with a threaded portion, wherein the threaded portions of the pawls oppose each other.
12 . A stylet feeder for connection to a surgical tool, the stylet feeder comprising:
a base for attaching to the surgical tool, the base having a platform and a skirt extending distally from the platform, the skirt including at least one lateral protrusion extending outward,
wherein the base defines a passage extending in a proximal-distal direction such that the stylet feeder is cannulated for accepting a stylet therethrough.
13 . The stylet feeder of claim 12 , further comprising an extension protruding proximally from the platform of the base, the extension having a proximal end housing a pawl, the pawl having a distal end with a threaded portion.
14 . The stylet feeder of claim 12 , wherein the skirt defines a slit passing between opposing ends of the skirt when the stylet feeder is in a resting configuration.
15 . The stylet feeder of claim 14 , wherein the slit passes through a portion of the platform.
16 . The stylet feeder of claim 12 , wherein the skirt and the platform define a cavity into which a proximal end of a surgical tool can be disposed and secured.
17 . The stylet feeder of claim 12 , wherein each of the lateral protrusions define an aperture therethrough for connection with a fastener.
18 . The stylet feeder of claim 17 , further comprising a fastener disposed through the apertures of the lateral protrusions and configured to force the lateral protrusions toward each other and into a clamped configuration.
19 . A method of using a stylet feeder for connection to a surgical tool, comprising:
placing a base of the stylet feeder on an end of the surgical tool so that a portion of the base surrounds the end of the surgical tool and so that a portion of a stylet passes into a passage of the base; and
adjusting the base to secure the stylet feeder to the end of the surgical tool.
20 . The method of claim 19 , further comprising adjusting the base of the stylet feeder to complement an end of the surgical tool before placing the base on the end of the surgical tool.
