Abstract
A surgical instrument for the dissection of bone and other tissue includes a spindle, a dissection tool and an coupler disposed between the spindle and the dissection tool. The coupler includes a tool collet and an attachment locking mechanism operable to permit tool collet operation and telescoping movement of an attachment tube with respect to the dissection tool. A method is also provided for convenient coupling of the dissection tool and adjustment of the attachment tube length.
Claims21
A method of assembling a surgical instrument, comprising:
- providing a motor assembly with a first tool chuck;
- providing a coupling assembly with a work shaft and a second tool chuck;
- providing an attachment tube;
- providing a dissection tool having a distal working portion and a proximal coupling portion;
- securing the coupling assembly to the motor assembly by engaging the work shaft with the first tool chuck;
- inserting the attachment tube into an axial bore of the coupling assembly to movably couple the attachment tube to the coupling assembly;
- inserting the proximal portion of the dissection tool through the attachment tube and into the second tool chuck;
- and
- locking the proximal portion of the dissection tool in the second tool chuck.
A method of assembling a surgical instrument, comprising:
- securing a coupling assembly to a motor assembly by engaging a work shaft with a first tool chuck;
- inserting an attachment tube into an axial bore of the coupling assembly to movably couple the attachment tube to the coupling assembly;
- inserting a proximal portion of a tool through the attachment tube and into a second tool chuck;
- locking a proximal coupling portion of the tool in the second tool chuck;
- and
- translating the attachment tube along the tool after locking the proximal portion of the tool in the second tool chuck to adjust an amount of a working portion of the tool that extends distally from the attachment tube.
A method of assembling a surgical instrument, comprising:
- securing an attachment base to a motor assembly of the surgical instrument;
- inserting an attachment tube into an axial bore of the attachment base assembly to movably couple the attachment tube to the attachment base;
- locking a proximal coupling portion of the tool in a tool locking assembly coupled to the motor assembly by the attachment base;
- and
- allowing translation of the attachment tube along the tool after locking the proximal portion of the tool in the tool locking assembly.
