Abstract
A medical instrument for closing an opening for surgery in which a trocar is used, and a method of securely closing the opening. The instrument includes a hollow tube, into which is inserted an elongated actuating mechanism, having at least two needles that can be positioned in a closed or open position. By securing a suture on the needles, inserting the instrument into the surgical opening, placing the needle into the open position, withdrawing the instrument through the body tissue, and tying the sutures, a secure closure of the surgical opening can be achieved.
Claims19
A medical instrument for closing an opening for surgery, comprising:
- an elongated cylindrical member having an open proximal end and a closed distal end;
- an actuating mechanism being operatively positioned within the cylindrical member;
- at least two elongated needles secured to the cylindrical member and engaging with the actuating mechanism;
- the at least two elongated needles include proximal ends capable of retaining a suture, the at least two needles being movable by the actuating mechanism from a closed position adjacent to an outer surface of the cylindrical member to an open position,
- wherein in the open position the proximal ends of the at least two needles extend away for the outer surface of the cylindrical member.
A method for closing a surgical opening employing a medical instrument having a cylindrical member, an actuating mechanism, and at least two elongated needles, the method comprising the steps of:
- securing a suture to the at least two needles and to a distal end of the cylindrical member;
- retracting the at least two needles, so that the at least two needles lie adjacent to an outer surface of the cylindrical member;
- inserting the medical instrument until proximal ends of the at least two needles are below an inner most layer of tissue;
- deploying needles to an open position;
- withdrawing the medical instrument until the suture appears above the skin layer of a patient;
- removing ends of the suture from the needles;
- reinserting the medical instrument while still in an opening position until the proximal ends of the at least two needles are below the inner most layer of tissue;
- retracting the at least two needles so that needles are returned to a closed position and below the outer surface of the cylindrical member;
- withdrawing the instrument;
- retrieving ends of the suture in a subcutaneous tissue;
- and
- tying required knots in the suture, the knots closing the surgical opening.
