Apparatus and method for excising tissue and bandaging the resulting wound
View Patent ↗An apparatus ( 10 ) and method for excising tissue ( 208 ) and closing a wound ( 156 ) that results from excision of the tissue ( 208 ) is provided. The apparatus ( 10 ) includes structure ( 14 ) defining an aperture ( 34 ) into which tissue ( 208 ) to be excised is exposed and a cutting member ( 96 ). The apparatus ( 10 ) also includes an adhesive bandage ( 140 ) for closing the wound ( 156 ). The adhesive bandage ( 140 ) is secured relative to a lower surface ( 20 ) of the structure ( 14 ) in a location for contacting skin ( 154 ) adjacent to the tissue ( 208 ) to be excised. The apparatus ( 10 ) further includes a device ( 150 ) that is actuatable for closing the wound ( 156 ) with the adhesive bandage ( 140 ) and actuators ( 108 and 182 ) for moving the cutting member ( 96 ) relative to the structure ( 14 ) for excising the tissue ( 208 ) exposed in the aperture ( 34 ) and for actuating the device ( 150 ).
1. An apparatus for excising tissue and closing a wound that results from excision of the tissue, the apparatus comprising:
a structure defining an aperture into which tissue to be excised is exposed;
a cutting member;
an adhesive bandage strip for mechanically closing the wound, the adhesive bandage strip secured relative to a lower surface of the structure in a location for contacting skin adjacent to the tissue to be excised;
a device actuatable for closing the wound with the adhesive bandage strip; and
actuators for moving the cutting member relative to the structure for excising the tissue exposed in the aperture and for actuating the device.
2. The apparatus of claim 1 wherein the device includes a liner to which a portion of the adhesive bandage strip is attached, actuation of the device moving the liner relative to the lower surface of the structure to close the wound with the adhesive bandage strip.
3. The apparatus of claim 2 wherein, prior to actuation of the device, the liner lies adjacent to the lower surface of the structure, the adhesive bandage strip being secured to the liner.
4. The apparatus of claim 3 wherein the liner includes an opening and the aperture of the structure is elliptical, the opening of the liner aligning with the aperture of the structure when the liner is secured relative to the lower surface of the structure.
5. The apparatus of claim 4 wherein the liner is formed from a resilient material, the elliptical opening deforming during actuation of the device.
6. The apparatus of claim 2 wherein the device further includes at least one roller member over which the liner is moved during actuation.
7. The apparatus of claim 2 wherein the device is configured to move the liner over a distance greater than a distance traveled by the actuator for actuating the device.
8. The apparatus of claim 6 wherein the device includes two roller members over which the liner is moved during actuation, the liner moving over a distance greater than 1:1 of a distance traveled by the actuator for actuating the device.
9. The apparatus of claim 2 wherein the actuator for actuating the device is formed at an end of the liner.
10. The apparatus of claim 9 wherein, to actuate the device, the actuator for actuating the device is manually grasped and is pulled in a direction away from the structure.
11. The apparatus of claim 2 wherein the liner is a first liner and the device also includes a second liner for closing the wound, the adhesive bandage strip being a first adhesive bandage strip and being associated with the first liner for closing the wound, a second adhesive bandage strip for closing the wound being associated with the second liner, actuation of the device closing the wound with the first and second adhesive bandage strips.
12. The apparatus of claim 1 further including skin grippers associated with the actuators and including tines for gripping the skin adjacent the tissue to be excised.
13. The apparatus of claim 12 wherein the tines secure the skin adjacent to the tissue to be excised for enabling the tissue to be excised to be tensioned.
14. The apparatus of claim 12 wherein the tines move together for pressing together opposite edges of the wound prior to the adhesive bandage strip closing the wound.
