Suturing Device

A suturing device adapted for sewing two tubular objects together, each of the tubular objects having a connecting opening, the suturing device comprising:

• a suturing unit including
• a suturing aid rod that is elongated in a first direction and that has two carrying portions opposite to each other in the first direction, each of the carrying portions having a carrying section that is proximate to another one of the carrying portions, an insertion section that is distal from the another one of the carrying portions and that is adapted to be inserted into the connecting opening of a respective one of the tubular object, and a plurality of grooves that are disposed about an axis extending in the first direction, for each of the carrying portions, each of the grooves extending in the first direction and having a first accommodating part that is located at the insertion section, and that has a curved area and a needle opening spatially communicating with the curved area and located at the insertion section, the curved area of the first accommodating part of each of the grooves having two side segments that are spaced apart from each other in the first direction and that are distal from the axis, and a middle segment that interconnects the side segments and that is proximate to the axis,
• a plurality of sewing subunits each of which includes a suture thread and two suture needles that are respectively connected to two opposite ends of the suture thread, one of the suture needles of each of the sewing subunits being disposed on the curved area of the first accommodating part of a respective one of the grooves of one of the carrying portions and having a cross-section that is shaped to correspond to a cross-section of the curved area of the first accommodating part of the respective one of the grooves of the one of the carrying portions, the other one of the suture needles of each of the sewing subunits being disposed on the curved area of the first accommodating part of a respective one of the grooves of the other one of the carrying portions and having a cross-section that is shaped to correspond to a cross-section of the curved area of the first accommodating part of the respective one of the grooves of the other one of the carrying portions, and
• two pushing subunits each of which is mounted to a respective one of the carrying portions and is slidable relative to the respective one of the carrying portions between an initial position and a puncture position in the first direction, the pushing subunits being proximate to a center of the suturing aid rod when the pushing subunits are in the initial position, the pushing subunits being operable to move away from each other toward the puncture position so that the pushing subunits respectively push the suture needles of the sewing subunits and urge the suture needles to respectively slide along the curved areas of the grooves and respectively protrude out of the needle opening of the grooves, when the pushing subunits are in the puncture position, one of the suture needles of each of the sewing subunits being adapted to puncture one of the tubular objects, and the other one of the suture needles of each of the sewing subunits being adapted to puncture the other one of the tubular objects.
