Abstract
A drive mechanism for operating a suturing mechanism includes a user input displaceable through a range of motion and a linkage mechanically associated with the user input and with a shuttle transmitter of the suturing mechanism. The linkage converts displacements of the user input unidirectionally or bidirectionally into a sequence of operations of the shuttle transmitter including sufficient to perform a sequence of operations of the suturing mechanism to perform successive bidirectional stitching, with the shuttle transmitter penetrating tissue alternately with and without a shuttle needle attached.
Claims20
A suturing device comprising:
- a suturing mechanism comprising:
- a shuttle for holding a suture, and
- a shuttle transmitter for controlling motion of said shuttle, said shuttle transmitter being displaceable along a longitudinal axis between a withdrawn position and a penetrating position, said shuttle transmitter being reconfigurable between a shuttle holding state configured to retain said shuttle in an engaged position engaged with said shuttle transmitter and a shuttle releasing state configured to release said shuttle from said engaged position;
- and
- a drive mechanism for operating said suturing mechanism, said drive mechanism comprising:
- (a) a user input displaceable through a range of motion between a position A and a position B;
- and
- (b) a linkage mechanically associated with said user input and with said shuttle transmitter, said linkage configured to be actuated solely by displacements of said user input such that, when actuated by one or more unidirectional or bidirectionally displacements of said user input through said range of motion between positions A and B, said linkage generates a sequence of operations of said shuttle transmitter, said sequence of operations comprising:
- (i) displacement of said shuttle transmitter while engaged with said shuttle along said longitudinal axis from said withdrawn position to said penetrating position so as to penetrate the material at a first location;
- (ii) reconfiguration of said shuttle transmitter from said shuttle holding state to said shuttle releasing state;
- and
- (iii) displacement of said shuttle transmitter in said shuttle releasing state along said longitudinal axis from said penetrating position to said withdrawn position so as to withdraw from the material leaving a first suture stitch at the first location;
- said linkage further configured to be actuated solely by said user input such that, after repositioning of said shuttle transmitter and said shuttle aligned at a second location, when actuated by one or more unidirectional or bidirectional displacements of said user input through said range of motion between positions A and B, said linkage generates a further sequence of operations of said shuttle transmitter, said further sequence of operations comprising:
- (iv) displacement of said shuttle transmitter in said shuttle releasing state along said longitudinal axis from said withdrawn position to said penetrating position so as to penetrate the material at the second location;
- (v) reconfiguration of said shuttle transmitter from said shuttle releasing state to said shuttle holding state so as to hold said shuttle;
- and
- (vi) displacement of said shuttle transmitter along said longitudinal axis from said penetrating position to said withdrawn position so as to withdraw said shuttle from said material forming a second suture stitch at the second location,
- wherein said reconfiguration of said shuttle transmitter from said shuttle holding state to said shuttle releasing state generates a tissue penetrating configuration of said shuttle transmitter without said shuttle, and wherein said reconfiguration of said shuttle transmitter from said shuttle releasing state to said shuttle holding state generates a tissue penetrating configuration of said shuttle transmitter together with said shuttle,
- and wherein said shuttle transmitter comprises a shuttle holder and a shuttle ejector, and wherein reconfiguration of said shuttle transmitter between said shuttle holding state and said shuttle releasing state is effected by motion of said shuttle ejector relative to said shuttle holder along said longitudinal axis.
