Surgical tool and method for soft ocular tissue transplantation

A surgical device for performing tissue transplantation within an eye comprising:

• a hollow handle portion configured to convey a liquid fluid through the hollow handle portion, the hollow handle portion having a distal end;
• and
• an injector portion fluidically coupled to the hollow handle portion and defining an internal channel via which the liquid fluid is conveyed, the injector portion comprising:
• an elongate body portion having opposing distal and proximal ends defining the internal channel extending from the distal end to the proximal end configured to enshroud a tissue for transplantation, wherein the tissue is held in place within the internal channel when a vacuum pressure is applied to the tissue via liquid fluid present in the internal channel, the proximal end of the elongate body portion being securely coupled to the distal end of the hollow handle portion to receive liquid fluid conveyed through the hollow handle portion;
• a tip portion defined at the distal end of the elongate body portion configured for insertion into an eye;
• and
• an open region defined at the distal end of the elongate body portion in fluid communication with the internal channel such that the tissue within the internal channel is expelled from the open region and injected into the eye when an injection pressure opposing the vacuum pressure is applied to the tissue via the liquid fluid in the internal channel.
