Two-way grasping forceps for digestive endoscope

Abstract

The invention discloses a bidirectional grasping forceps for digestive endoscope, comprising a sleeve, a push cylinder, a rotating rod and a closing mechanism. The two sides of the groove are symmetrically hinged with foot posts, and the end of the foot post is hinged with a foot block; the push cylinder is installed in the casing and the outer wall is threadedly connected with the screw sleeve; the rotating rod is installed inside the push cylinder and is located in the casing. The end is provided with a main gear, and the end located outside the push cylinder is provided with a nut; the closing mechanism is hinged with the foot post and the push cylinder respectively, and the closing mechanism is folded or unfolded with the up and down movement of the push cylinder. The mechanism moves relatively with the rotation of the rotating rod, and the position of the closing mechanism is fixed in real time when the rotating rod moves. When pulling and closing the tissue, use horizontal force to better close the perforation site and reduce tissue damage.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bidirectional grasping forceps for digestive endoscope. Background technique [0002] Gastrointestinal perforation is a common surgical acute abdomen in clinical practice. Save the patient from suffering huge surgical trauma; at present, clips are mainly used for clamping and closing. When using clips for clamping and closing, the clip has an angle relative to the tissue, and the contact with the tissue is small and it is easy to pierce the tissue when clamping; and the existing clamping The force exerted by the device during clamping is divided into horizontal force and vertical force. The force in the horizontal direction makes the tissue close the perforation, and the force in the vertical direction pulls the tissue to move upward. Greater force is applied, and the moving distance of the pulled tissue is larger, which is likely to cause tissue damage; and it is ...

AI Technical Summary

Problems solved by technology

[0005] 2. The force applied by the existing clamping device during clamping is divided into horizontal force and vertical force. The force in the horizontal direction makes the tissue close the perforation, and the force in the vertical direction pulls the tissue upward. Move, when clamping, it needs to apply more force, and pull the tissue to move a larger distance, which is easy to cause tissue damage

[0006] 3. It is difficult for the currently used clips to fix the moving distance of the pulled tissue in real time during the clamping process
