Abstract
A suturing device for sewing animal skin or flesh having a reversely movable arcuate needle and a pivotal rocker arm, said needle and rocker arm being movable in planes at substantially right angles to each other whereby said rocker arm affords a loop in the suturing thread for each succeeding stitch afforded by the needle. When operating, the device includes a continually operating electric motor having clutch means for engaging and disengaging, as desired, a drive shaft and a driven shaft, the latter affording pivotal movement to the needle by means of an extension on the driven shaft which alternately engages drive elements on a pivotal shaft which is attached to the needle. The rocker arm is driven by the driven shaft by engagement of lugs on the driven shaft and a rocker arm shaft parallel thereto.
Claims15
A suturing device comprising in combination,
- a housing,
- a motor in said housing having a rotatable drive shaft,
- suturing apparatus including a movably mounted suturing needle and a source of suturing thread therefor, and a rotatably mounted driven shaft for moving said needle,
- and clutch means interposed between said drive and driven shafts comprising a continually rotating lug on said drive shaft and a catch member movably mounted relative to said driven shaft and biased into a position to be engaged by said lug,
- said clutch means further including a cam member movably mounted relative to said housing and having a cam surface normally positioned to move said catch member against its bias to position it out of said first mentioned position for engagement by said lug to thereby prevent rotation of said driven shaft by said drive shaft,
- said cam member being movable to a position where said cam surface is prevented from overcoming said bias and disengaging said catch member from said lug to thereby permit said lug to engage said catch member and effect rotation of said driven shaft by said drive shaft.
A suturing device comprising in combination,
- a housing,
- a motor in said housing having a rotatable drive shaft,
- suturing apparatus including a reversely movable suturing needle and a source of suturing thread therefor,
- a reversely pivotal shaft having connection with said needle such that reverse pivotal movement thereof effects reverse movement of said needle,
- a pair of spaced drive elements attached to and extending from said pivotal shaft in generally parallel relation to each other,
- and a rotatable driven shaft to be connected to said drive shaft and mounted at an angle to said pivotal shaft and between said drive elements, said driven shaft having an extension thereon for engagement alternatively with said drive elements, whereby as the driven shaft is rotated in one direction said extension alternately engages said drive elements to effect reverse pivotal movement of said pivotal shaft.
A suturing device comprising in combination,
- a housing,
- a motor in said housing having a rotatable drive shaft,
- suturing apparatus including a movably mounted suturing needle and a source of suturing thread therefor,
- a rotatably mounted driven shaft interposed between said drive shaft and said suturing apparatus,
- clutch means interposed between said drive and driven shafts comprising a continually rotating lug on said drive shaft and a catch member movably mounted relative to said driven shaft engageable by said lug,
- said clutch means further including a cam member movably mounted relative to said housing and having a cam surface normally positioned to disengage said catch member from said lug to prevent rotation of said driven shaft by said drive shaft, said cam member being movable to a position where said cam surface is prevented from disengaging said catch member from said lug to permit rotation of said driven shaft by said drive shaft,
- a reversely pivotal shaft having connection with said needle such that reverse pivotal movement of said pivotal shaft effects reverse movement of said needle,
- a pair of spaced drive elements attached to and extending from said pivotal shaft in generally parallel relation,
- and an extension formed on said driven shaft for engaging said drive elements alternately as said driven shaft is continually rotated in the same direction to thereby afford reverse movement of said needle.
