An applicator device for use in surgical procedures comprising: an applicator assembly having a handle and a double-barreled syringe removably mounted to the handle wherein the double-barreled syringe includes a first cylinder and a second cylinder, each cylinder including a pressure intake port (82; 88) at a proximal end and a fluid discharge port (80, 86) at a distal end; and a regulator assembly connected to the applicator assembly for providing a source of pressure to the applicator assembly, an atomizing tip provided at a distal end of the handle wherein the atomizing tip is in fluid communication with the double-barreled syringe, the regulator assembly including a first regulator and a second regulator in fluid communication with the respective pressure intake ports (82, 88) of the first and second cylinders (30, 32), and a third regulator in flow communication with a pressure inlet port disposed on the applicator, characterised in that the atomizing tip includes an atomizing chamber configured to receive a first and a second composition received from the double-barreled syringe and a discharge tube to apply a mixture of the first and second compositions to tissue, wherein the atomizing chamber is in fluid communication with pressure inlet port such that air pressure forced through third pressure inlet port facilitates mixing and atomization of the first and second compositions, and wherein each of the first, second and third regulators (34, 36,49) is independently adjustable from one another and configured to provide differing pressure levels to the pressure intake ports (82, 88) and pressure inlet port. an applicator assembly having a handle and a double-barreled syringe removably mounted to the handle wherein the double-barreled syringe includes a first cylinder and a second cylinder, each cylinder including a pressure intake port (82; 88) at a proximal end and a fluid discharge port (80, 86) at a distal end; and a regulator assembly connected to the applicator assembly for providing a source of pressure to the applicator assembly, an atomizing tip provided at a distal end of the handle wherein the atomizing tip is in fluid communication with the double-barreled syringe, the regulator assembly including a first regulator and a second regulator in fluid communication with the respective pressure intake ports (82, 88) of the first and second cylinders (30, 32), and a third regulator in flow communication with a pressure inlet port disposed on the applicator, characterised in that the atomizing tip includes an atomizing chamber configured to receive a first and a second composition received from the double-barreled syringe and a discharge tube to apply a mixture of the first and second compositions to tissue, wherein the atomizing chamber is in fluid communication with pressure inlet port such that air pressure forced through third pressure inlet port facilitates mixing and atomization of the first and second compositions, and wherein each of the first, second and third regulators (34, 36,49) is independently adjustable from one another and configured to provide differing pressure levels to the pressure intake ports (82, 88) and pressure inlet port.
