Description

Foreign body forceps for digestive tract

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a pair of foreign body forceps for digestive tracts.

Background

The foreign body forceps are medical appliances, are used for forceps and removing foreign bodies in the digestive tract of a human body, and are easy to cause direct damage to the digestive tract due to the fact that the foreign bodies are clamped in the digestive tract, so that conditions of mucosal erosion ulcer, digestive tract hemorrhage and the like of the digestive tract are caused.

In the prior art, as disclosed in Chinese patent publication No.: CN214907903U discloses a special pliers of alimentary canal foreign matter, it includes fixed handle, movable handle the spout has been seted up on the fixed handle, the fixed slider that is provided with of movable handle, slider and pull rod fixed connection, fixed handle is close to the fixed pull rod protective housing that is provided with in movable handle one side, fixed handle is close to pull rod outside cover between pull rod protective housing one side and the slider and is equipped with first spring, pull rod is kept away from fixed handle one side and is passed through pull rod fixed jaw, two jaws pass through jaw fixed pin fixed connection, be provided with the second spring between two jaws, all be equipped with harmless conical tooth on the jaw. In a word, the utility model has reasonable structural design, safe and convenient use and can not fall off randomly when the conical teeth grab foreign matters.

Although the special embedding of alimentary canal foreign matter in above-mentioned patent is through setting up the toper tooth, can not drop at will when having played snatching the foreign matter, but, the foreign matter pincers are as a medical instrument that often uses for carry out pincers and get the foreign matter in the alimentary canal, the foreign matter pincers in above-mentioned patent drive two pincers pinches through the pull rod, push away two pincers through the spring, because the pull rod is in order to guarantee certain intensity, because the spring needs to possess certain elasticity, pull rod and spring can only reduce the diameter under the circumstances that possess enough intensity and elasticity, thereby lead to the shell diameter of foreign matter pincers to hardly reduce, make the movable range of foreign matter pincers in the alimentary canal inside very little, inconvenient operation, consequently, to above-mentioned problem, we propose novel alimentary canal foreign matter pincers.

Disclosure of Invention

The utility model aims to solve the problems that in the prior art, a foreign body forceps drives two forceps jaws to be clamped by a pull rod, the two forceps jaws are pushed away by a spring, and the pull rod and the spring only can reduce the diameter under the condition of ensuring enough strength and elasticity because the pull rod is required to have certain elasticity for ensuring certain strength, so that the diameter of a shell of the foreign body forceps is difficult to reduce, the moving range of the foreign body forceps in the digestive tract is small, and the foreign body forceps are inconvenient to operate.
