Surgical tool and method

A method of performing corneal surgery, the method comprising:

• (a) providing a surgical tool assembly including:
• (i) a forceps instrument including a proximal handle portion with an actuator, and a distal forceps portion including jaws, where the actuator selectively moves the jaws;
• (ii) an infusion assembly including a tube configured to be connected to a fluid source at a first tube end and connected to a fitting at a second tube end, an infusion sleeve extending away from the fitting, the fitting defines a passage configured to receive the distal forceps portion of the forceps instrument, the infusion sleeve being arranged concentric around an outer surface of the distal forceps portion to define a fluid pathway, and the jaws extend beyond a terminal end of the infusion sleeve such that the jaws are arranged outside of the infusion sleeve;
• and
• (b) cutting two incisions on the anterior chamber of the patient's eye;
• (c) placing the donor tissue adjacent to a primary incision;
• (d) inserting the distal forceps portion of the forceps instrument through a paracentesis incision through the anterior chamber of the patient's eye and out of the primary incision;
• (e) securing the donor tissue via the jaws and withdrawing the distal forceps portion back through the primary incision and into the anterior chamber of the patient's eye at an installation site;
• (f) providing pressurized fluid to the fluid pathway of the infusion sleeve while gripping the donor issue to orient and unscroll the donor tissue at the implantation site;
• and
• (g) while holding the donor tissue in position, an amount of fluid is aspirated to shallow the anterior chamber of the patient's eye to prevent the donor tissue from scrolling.

A method of positioning and placing corneal donor tissue in the anterior chamber of a patient's eye, the method comprising:

• (a) providing a surgical tool assembly including:
• (i) a forceps instrument including a proximal handle portion with an actuator, and a distal forceps portion including jaws, where the actuator selectively moves the jaws;
• (ii) an infusion assembly including a tube configured to be connected to a fluid source at a primary tube end and connected to a fitting at a paracentesis tube end, an infusion sleeve extending away from the fitting, the fitting defines a passage configured to receive the distal forceps portion of the forceps instrument, the infusion sleeve being arranged concentric around an outer surface of the distal forceps portion to define a fluid pathway, and the jaws extend beyond a terminal end of the infusion sleeve such that the jaws are arranged outside of the infusion sleeve;
• and
• (iii) a donor tissue preparation tool configured to support a donor tissue;
• (b) placing donor tissue on the donor tissue preparation tool;
• (c) securing the donor tissue from the donor tissue preparation tool via the jaws and positioning the donor tissue into the anterior chamber of the patient's eye at an installation site;
• (d) providing pressurized fluid to the fluid pathway of the infusion sleeve while gripping the donor issue to orient and unscroll the donor tissue at the installation site;
• and
• (e) while holding the donor tissue in position, a small amount of fluid is aspirated to shallow the anterior chamber of the patient's eye to prevent the donor tissue from scrolling.

A configuration of a surgical tool securing a donor tissue, the configuration comprising

• (a) an assembly comprising:
• a forceps instrument including a proximal handle portion with an actuator, and a distal forceps portion including jaws, where the actuator selectively moves the jaws;
• and
• an infusion assembly including a tube configured to be connected to a fluid source at a primary tube end and connected to a fitting at a paracentesis tube end, the fitting defines a passage configured to receive the distal forceps portion of the forceps instrument, an infusion sleeve extending away from the fitting, the infusion sleeve being arranged concentric around an outer surface of the distal forceps portion to define a fluid pathway, and the jaws extend beyond a terminal end of the infusion sleeve such that the jaws are arranged outside of the infusion sleeve;
• and
• (b) a donor tissue.
