Background
The needle holder is also called needle holding forceps, the upper end is short, and a groove is arranged in the mouth for clamping the suture needle to suture and the needle holding forceps are knotted.
Surgical stapling is a surgical operation in which tissue, organs that have been cut or traumatically ruptured are apposed or have their passages reconstructed to restore their function. The correct use of the needle holder can ensure good apposition of the suture wound surface or the wound, is a basic condition for ensuring good healing of the traumatic tissue and organ, and is also the most important basic surgical operation technology.
When the needle holder is used, the thumb and the ring finger are respectively inserted into the two forceps handle circles. The two fingers should not be too long, wherein the thumb should not extend into the joint between the first finger, and the needle holder can be flexibly opened and closed by the force of the thumb on the ventral surface of the first finger joint and the ring finger in the suturing process.
The most common problem of beginners is that the thumb sleeved in the circular ring exceeds the first knuckle joint, and the needle holder is opened and closed by utilizing the strength of the metacarpophalangeal joint of the thumb and even the thenar, so that the operation deformation is caused, the opening and closing are inflexible, the action connection is not smooth, and the speed is low. The wrong holding mode greatly influences the learning effect of beginners and also influences the effect and efficiency of actual operation.
