Abstract

A first surgical instrument has a bore extending therethrough and includes a handle attachment site. A second surgical instrument is sized and configured for passage through the bore of the first instrument. The handle is adapted for manipulating the first instrument when in use and includes a component configured to removably engage the handle attachment site. The handle includes a passageway accommodating passage of the second instrument through the bore of the first instrument while the first instrument is removably engaged by the handle.

Claims

1. A method comprising

providing a system comprising a surgical instrument having a bore extending therethrough accommodating passage of a guide pin instrument and including a handle attachment site, a guide pin instrument sized and configured for passage through the bore of the surgical instrument, and a handle separate from the surgical instrument and the guide pin instrument including an attachment component configured to selectively engage or disengage the handle attachment site of the surgical instrument, and a passageway extending through the handle from the attachment component and accommodating passage of the guide pin instrument through the handle to accommodate sliding the handle over and relative to the guide pin instrument when selectively engaging or disengaging the attachment component and the handle attachment site,

deploying the guide pin instrument into a soft tissue region,

slidably advancing the surgical instrument over and relative to the guide pin instrument,

slidably advancing the handle over and relative to the guide pin instrument toward the surgical instrument to engage the attachment component with the handle attachment site,

manipulating the handle to manipulate the surgical instrument over and relative to the guide pin instrument in the soft tissue region, and

slidably withdrawing the handle over and relative to the guide pin instrument away from the surgical instrument to disengage the attachment component from the handle attachment site and separate the handle from the guide pin instrument.

2. A method according to claim 1

wherein the attachment component and the handle attachment site engage in a slip fit.

3. A method according to claim 1

wherein the surgical instrument comprises a cannula.

4. A method according to claim 1

wherein the surgical instrument comprises an obturator.

5. A method comprising

providing a system comprising an obturator instrument having a bore extending therethrough accommodating passage of a guide pin instrument and including an obturator handle attachment site, a cannula instrument having a bore extending therethrough accommodating passage of the obturator instrument and including a cannula handle attachment site, and a handle separate from the obturator instrument and the cannula instrument, the handle including spaced-apart first and second attachment components configured to selectively engage and disengage, respectively, the obturator handle attachment site and the cannula handle attachment site, the handle also including spaced-apart first and second passageways extending through the handle, respectively, from the first and second attachment components and accommodating passage of a guide pin instrument through the handle to accommodate sliding the handle over and relative to the guide pin instrument when selectively engaging or disengaging the respective attachment component and the respective handle attachment site,

deploying a guide pin instrument into a soft tissue region,

slidably advancing the obturator instrument over and relative to the guide pin instrument,

slidably advancing the handle over and relative to the guide pin instrument toward the obturator instrument to engage the first attachment component with the obturator handle attachment site,

manipulating the handle to manipulate the obturator instrument over and relative to the guide pin instrument in the soft tissue region,

slidably withdrawing the handle over and relative to the guide pin instrument away from the obturator instrument to disengage the first attachment component from the obturator handle attachment site and separate the handle from the guide pin instrument,

slidably advancing the cannula instrument over and relative to the guide pin instrument and the obturator instrument,

slidably advancing the handle over and relative to the guide pin instrument toward the cannula instrument to engage the second attachment component with the cannula handle attachment site, and

manipulating the handle to manipulate the cannula instrument over and relative to the guide pin instrument in the soft tissue region.

6. A method according to claim 5

wherein the first and second attachment components and the respective handle attachment sites engage in a slip fit.

7. A method according to claim 5 and further comprising

slidably withdrawing the handle over and relative to the guide pin instrument away the cannula instrument to disengage the second attachment component from the cannula handle attachment site and separate the handle from the guide pin instrument.

8. A method according to claim 7 and further comprising withdrawing the obturator instrument and the guide pin instrument from the cannula instrument.
