Abstract

A surgical suturing device for closing a wound or an incision having a first elongated needle holder having an end portion for grasping and releasing a thread end of a needle and a second elongated needle holder pivotally connected to the first elongated needle holder having an end portion for grasping and releasing an opposite pointed end portion of the needle. One end portion of an elongated rod is connected to pair of needle holders and moves the needle holders together and away from each other. An opposite end portion of the rod is attached to a pivotally attached handle which moves the rod. In each of the needle holders there is a latch which is actuated when the needle holders are brought together to simultaneously grasp one end portion of the needle and release the opposite end portion of the needle.

Claims

1. A surgical suturing device comprising:

a needle having a thread end portion and an opposite pointed end portion;

a pair of needle holders including a first elongated needle holder, said first needle holder having an end portion for grasping and releasing said thread end portion of said needle and a second elongated needle holder pivotally connected to said first needle holder and having an end portion for grasping and releasing said opposite pointed end portion of said needle, said needle holders being selectively movable between a closed position wherein said needle holders are adjacent to each other and an open position wherein said needle holders are angularly displaced apart from each other;

a means actuated by moving said needle holders to said closed position for simultaneously grasping said thread end portion of said needle in said first needle holder and releasing said pointed end portion in said second needle holder and thereafter simultaneously grasping said pointed end portion and releasing said thread end portion; and

a pair of handles for selectively moving said needle holders between said closed and said open positions.

2. The surgical suturing device recited in claim 1 wherein said means for grasping and releasing said needle'"'"'s end portion comprises in each of said needle holders a wedge for engaging an end portion of said needle and a latch for engaging and releasing said wedge.

3. The surgical suturing device recited in claim 2 further comprising in each of said needle holders a cam for operating said latch.

4. The suturing device recited in claim 1 further comprising a pair of links, each of said links having an end portion connected to an end portion of one of said handles and an opposite end portion connected to an opposite end portion of said other handle for moving a rod in an axial direction;

a rod having one end portion connected to said interconnected end portions of said links and an opposite end portion connected to said pair of needle holders for rotating said needle holders toward and away from each other.

5. The suturing device recited in claim 4 wherein each of said means for grasping and releasing said end portions of said needles includes a cam pivotally mounted to an exterior portion of each needle holder, said cam arranged on each of said needle holders for contacting and rotating each other when said needle holders are brought adjacent to each other to simultaneously grasp and release said end portions of said needle.

6. A surgical suturing device comprising:

a needle, said needle having a thread end portion and a pointed end portion;

a pair of pivotally connected needle holders, each of said needle holders having an end portion for grasping one of said end portions of said needle, each of said needle holder end portions having a movable tapered wedge and a fixed end portion for grasping one of said needle'"'"'s end portions, each of said needle holders further having a latch for simultaneously grasping one end portion of said needle and releasing an opposite end portion of said needle; and

a pair of handles for simultaneously actuating said means for grasping and releasing said opposite end portions of said needle.

7. A surgical suturing device comprising a needle, said needle having a thread end portion and an opposite pointed end portion;

a first elongated needle holder, said needle holder having an end portion for grasping and releasing said thread end portion of said needle;

a second elongated needle holder pivotally connected to said first needle holder and having an end portion for grasping and releasing said opposite pointed end portion of said needle;

a bracket having an angular slot attached to an end portion of each of said needle holders;

a thin elongated rod having an end portion connected to said angular slot of each of said needle holders and an opposite end portion connected to a movable handle;

a fixed handle;

a movable handle pivotally connected to said fixed handle.

8. In a surgical suturing device for closing a wound or an incision, the improvement comprising:

a needle having a thread end portion and a pointed end portion;

a fixed handle;

a movable handle pivotally connected to said movable handle;

a thin elongated rod having an end portion connected to said movable handle and an opposite end portion connected to a pair of needle holders;

a pair of needle holders, each of said needle holders having a means actuated by rotating said needle holders to a closed position adiacent to each other for alternately and simultaneously grasping one of said end portions of said needle and releasing the opposite end portion of said needle.

9. A surgical suturing device comprising:

a needle having a thread end portion and an opposite pointed end portion;

a first elongated needle holder, said needle holder having an end portion for grasping and releasing said thread end portion of said needle;

a second elongated needle holder pivotally connected to said first needle holder, having an end portion for grasping and releasing said opposite pointed end portion of said needle;

said needle holders being selectively rotatable between a closed position wherein side portions of said needle holders are adjacent to each other and an open position wherein said side portions are angularly apart from each other; and

a means for simultaneously rotating said needle holders to said position adjacent to each other, releasing said thread end portion of said needle in one of said needle holders and grasping said pointed end portion of said needle in said other needle holder.
