Abstract

The invention discloses a double-end endoscope flexible pipe type sampling tongs comprising a fixed jaw; two sides of the fixed jaw are respectively provided with a movable jaw; each movable jaw forms a sampling jaw with the fixed jaw, and respectively connected with a handle propeller through a haulage cable; each handle propeller respectively control one movable jaw to move through one haulage cable. The double-end endoscope flexible pipe type sampling tongs enters the human body, and two handle propellers can respectively control two movable jaws to move, thus obtaining two living tissue sample; in a same space and time, the double-end endoscope flexible pipe type sampling tongs can provide double pathology samples, can double the verification and measurement ratio, can reduce patient pains and operation time, and has less damages on the endoscope equipment.

Description

technical field [0001] The invention relates to a medical device, in particular to a hose-type sampling forceps for a double-headed endoscope. Background technique [0002] Endoscopic hose-type biopsy forceps mainly bite the living tissue of the stomach, intestinal tract or respiratory system through the soft endoscopic forceps for pathological analysis and testing. The specific structure is as follows: the jaws are connected with the steel wire rope through the traction steel wire, the end of the steel wire rope is connected with the operating handle, and the outside of the traction steel wire and the steel wire rope is covered with a sheath spring tube. However, the current jaws are generally single-headed, and only one living tissue specimen can be bitten at a time, while conventional pathological analysis tests usually require more than one specimen, so multiple sampling is required. Contents of the invention [0003] The purpose of the present invention is to provide...
