Abstract
Disclosed is a device, comprising a handle, a rotatable shaft, a sleeve comprising a first curved, hollow, stainless steel (magnetized) tube and a second curved, hollow, stainless steel (magnetized) tube, wherein the first tube is positioned on a first side of the shaft and the second tube is positioned on a second side of the shaft, wherein the first tube comprises a sharp tip and the second tube comprises a sharp tip, with a reciprocating shuttle and a curved needle positioned in the sleeve, wherein the sleeve having an inner diameter large enough to accommodate the needle and shuttle, and wherein the shuttle is positioned between the sleeve and the needle. Rotation of the shaft moves the shuttle which in turn moves the needle through the sleeve.
Claims16
A device comprising:
- a) a housing with a top end and a bottom end, and a first side and a second side, wherein the bottom end of the housing defines an opening;
- b) a first rotatable shaft with a first end and a second end, the first rotatable shaft coupled to a first roller gear proximal to the second end of the first rotatable shaft, the first roller gear and the second end of the first rotatable shaft positioned in the housing;
- c) a second rotatable shaft with first end and a second end, the second rotatable shaft coupled to a second roller gear proximal to the second end of the second rotatable shaft, the second roller gear and the second end of the second rotatable shaft positioned in the housing, wherein the first roller gear engages the second roller gear;
- d) a sleeve comprising a first curved, hollow, stainless steel, magnetized tube having a first end and a second end, the first end of the first tube having a first sharp tip, wherein the second end of the first tube is positioned on the first side of the housing, and a second curved, hollow, stainless steel, magnetized tube having a first end and a second end, the first end of the second tube having a second sharp tip, wherein the second end of the second tube is positioned on the second side of the housing;
- e) a reciprocating shuttle positioned in the sleeve;
- and
- f) a curved stainless steel, magnetized needle, positioned in the sleeve, wherein the sleeve having an inner diameter large enough to accommodate the needle and the shuttle, and wherein the shuttle is positioned between the sleeve and the needle, wherein the shuttle engages the needle, wherein the shuttle is coupled to the first and second rotatable shaft, and wherein a rotation of the first and second rotatable shaft moves the shuttle through the sleeve which in turn drives the needle through the sleeve.

A method for suturing tissue, comprising the steps of:
- a) providing a device comprising:
- i) a handle;
- ii) a housing with a top end and a bottom end, and a first side and a second side, wherein the bottom end of the housing defines an opening;
- iii) a rotatable shaft with a first end and a second end, the rotatable shaft coupled to a first roller gear proximal to the second end of the rotatable shaft, the first roller gear and the second end of the rotatable shaft positioned in the housing, the rotatable shaft coupled to the handle;
- iv) a second roller gear positioned in the housing and engaged with the first roller gear;
- v) a sleeve comprising a first curved, hollow, stainless steel, magnetized tube and a second curved, hollow, stainless steel, magnetized tube, wherein the first tube is positioned on a first side of the shaft and the second tube is positioned on a second side of the shaft, wherein the first tube comprises a first sharp tip and the second tube comprises a second sharp tip;
- vi) a reciprocating shuttle;
- and
- vii) a curved stainless steel, magnetized needle, positioned in the sleeve, wherein the sleeve having an inner diameter large enough to accommodate the needle and the shuttle, and wherein the shuttle is positioned between the sleeve and the needle, wherein the shuttle engages the needle, wherein the shuttle is coupled to the shaft, and wherein a rotation of the shaft moves the shuttle which in turn drives the needle through the sleeve;
- b) positioning the needle at an initial position in the sleeve;
- c) piercing the tissue with the sleeve;
- d) actuating the rotatable shaft in the forward direction to advance the shuttle in the first tube of the sleeve which advances the needle into the tissue;
- e) actuating the rotatable shaft in the opposite direction to retract the shuttle into the second tube of the sleeve;
- f) repeating steps c) and d) until the needle is positioned in the initial position within the sleeve;
- and
- g) repeating steps b) through e) until completion of the suturing process.
