Apparatus and method for minimally invasive suturing |
摘要 |
An apparatus and method for minimally invasive suturing is disclosed. A suturing device for minimally invasive suturing includes proximal section having a proximal end, a distal end, and a longitudinal axis therebetween; a suture head assembly extending from the distal end of the proximal section; a suturing needle having a pointed end and a blunt end, the suturing needle capable of rotating about an axis approximately perpendicular to a longitudinal axis of the proximal section, wherein the pointed end of the suturing needle is positioned within the suture head assembly prior to and after rotation of the suturing needle; and an actuator extending from the proximal end of the proximal section to actuate a drive mechanism having a needle driver for engaging and rotating the suturing needle. |

1. A suturing device comprising a suturing head, the suturing head comprising:
a) a needle track housing portion including a needle disposed in a needle track, the needle track being adapted and configured to guide the needle along a curved path about an axis of rotation substantially perpendicular to a longitudinal axis of the suturing head, the needle having:
(i) a curved body, the curved body covering an arc greater than about 180°; and(ii) an engagement surface for driving the needle; and b) a drive housing portion containing a drive, wherein the drive includes an elongate flexible member comprising a ribbon, at least a portion of the elongate flexible member being operative to reciprocate along a direction substantially parallel to the longitudinal axis, the elongate flexible member being further operative to engage the engagement surface of the needle and advance and retract the needle through a circular arc as the elongate flexible member is advanced and retracted along the longitudinal axis during reciprocation. |
