Multi-implement surgical device
A device for surgery that accommodates multiple different implements. The implements may be exchanged or changed out for one another over the course of a surgery in a manner that does not require disengagement of the device from a surgical site. As a result, the need to re-insert the device into the patient and other hazards associated with multiple trips into the surgical site may be minimized. In one embodiment, the device includes cannula architecture to avoid use of a separate cannula at the surgical site.
1 . A multi-implement device for surgery at a surgical site on a patient, the device comprising:
a tubular guide;
a first retractable surgical implement to extend from a body of the device and through the tubular guide to facilitate a first application during the surgery; and
a second retractable surgical implement to extend from the body and through the tubular guide to facilitate a second application during the surgery, the first retractable surgical implement retracted through the tubular guide during the extending of the second retractable surgical implement;
wherein the device comprises a proximal end and a distal end;
wherein the tubular guide extends from the distal end;
wherein the first retractable surgical implement comprises a first driving mandrel coupled to a first actuator specific to the first retractable surgical implement;
wherein the second retractable surgical implement comprises a second driving mandrel coupled to a second actuator specific to the second retractable surgical implement;
wherein the first and second actuator are accessible by a finger of a user and are configured to be driven linearly toward the distal end upon being depressed by the finger toward the distal end for deployment of a corresponding first or second retractable surgical implement; and
wherein depression of the first or second actuator by the finger toward the distal end results in a corresponding release of the other of the first or second actuator and a subsequent linear travel of the other of the first or second retractable surgical implement toward the proximal end of the device to retract the corresponding first or second retractable surgical implement.
2 . The multi-implement device of claim 1 wherein the retractable surgical implements are selected from a group consisting of a vitrectomy probe, forceps, a backflush device, scissors, a soft tip cannula, a laser tool, a scraper, a light, and a diathermy tool.
3 . The multi-implement device of claim 1 further comprising one of backflush, a soft tip cannula and vitrectomy tubing coupled to the body at an end opposite an end from which the implements extend.
4 . The multi-implement device of claim 1 , wherein the tubular guide is configured to interface with a cannula at the surgical site.
5 . The multi-implement device of claim 1 , wherein the first and second actuators are provided with different visibly distinctive indicators for a surgeon to differentiate the implements.
6 . The multi-implement device of claim 5 wherein the visibly distinctive indicators are different colors.
7 . The multi-implement device of claim 1 , further comprising a third retractable surgical implement to extend from the body and through the tubular guide to facilitate a third application during the surgery, the first or second retractable surgical implements retracted through the tubular guide during the extending of the third retractable surgical implement.
8 . The multi-implement device of claim 7 ,
wherein the third retractable surgical implement comprises a third driving mandrel coupled to a third actuator specific to the third retractable surgical implement;
wherein the third actuator is accessible by the finger of the user and is configured to be driven linearly toward the distal end upon being depressed by the finger toward the distal end for deployment of the third retractable surgical implement; and
wherein depression of the third actuator by the finger toward the distal end results in a corresponding release of any deployed actuator of the first and second actuator and a subsequent linear travel of the corresponding deployed first or second retractable surgical implement toward the proximal end of the device to retract the corresponding first or second retractable surgical implement.
