Tissue grasping forceps

Abstract

The invention relates to a pair of tissue grasping forceps. The pair of tissue grasping forceps comprises a puncture sleeve which is provided with an edged bottom end, a shell fixedly arranged at the upper end of the puncture sleeve, a pull rod, a handle A and a clamp which are respectively fixedly arranged at upper and lower ends of the pull rod, as well as a spring A, wherein a passage is formed in the puncture sleeve and runs through up and down; a cavity communicated with the passage is formed in the shell and runs through up and down; the pull rod penetrates the cavity and runs through the passage; the handle A is accommodated in the cavity; the clamp is positioned at the bottom end of the puncture sleeve; the spring A is arranged in the cavity; the pull rod runs through the spring A and enters the passage; when the handle A is pressed down, the spring A is compressed, and the clamp is protruded from the puncture sleeve and expands; and when the handle A is released, the spring A is returned, the handle A is promoted to move upward with the pull rod, and the clamp enters the puncture sleeve and is controlled by the puncture sleeve and is closed. The pair of tissue grasping forceps has a simple structure, and can be used for avoiding the situation that the clamp carrying a tissue integrally enters the puncture sleeve, and the tissue along with the clamp enters the puncture sleeve to hurt the tissue.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a tissue grasping forceps. Background technique [0002] In laparoscopic surgery, it is necessary to use grasping forceps to grasp, pull, and dissociate the micro-organs around the lesion, and to position the micro-organs after being towed and mobilized. Most grasping forceps mainly include a puncture sleeve, a housing fixed on the upper end of the puncture sleeve, a pull rod located in the puncture sleeve, and handles and clamps respectively fixed on the upper and lower ends of the pull rod. The jaw moves up and down and realizes opening and closing. The grasping forceps are almost all operated with one hand. The traditional grasping forceps lacks a reset device, so that when the forceps clamp the tissue, because the clamped tissue will generate a restoring force, it is only controlled by pulling the handle upwards with one hand. The upward movement of the jaws will become i...

AI Technical Summary

Problems solved by technology

The grasping forceps are almost all operated with one hand. The traditional grasping forceps lacks a reset device, so that when the forceps clamp the tissue, because the clamped tissue will generate a restoring force, it is only controlled by pulling the handle upwards with one hand. The upward movement of the jaws will become inconvenient, laborious, and difficult to control the pulling force. It is easy to pull the tissue into the puncture cannula during operation, causing damage to the tissue; moreover, the traditional grasping forceps has no positioning device and must be manually Positioning brings unnecessary trouble to the operation and cannot meet the ideal application effect of the operation
