Foreign matter extraction combined instrument for rhinolaryngology department

Abstract

The invention provides a foreign matter extraction combined instrument for rhinolaryngology department. the foreign matter extraction combined instrument comprises a workbench, wherein a placing groove is formed in one side of the upper surface of the workbench, extraction tweezers are arranged in the placing groove, the extraction tweezers comprise tweezer main rods, a clamping blade is arrangedat one end of the inner wall of each tweezer main rod, and a small spring is arranged at the other end of the inner wall of each tweezer main rod; three limiting holes are formed in one side of the outer wall of each tweezer main rod in parallel in an equal spacing manner, a hemispherical limiting block is arranged in one limiting hole of each tweezer main rod, a reset spring is arranged at one end of each hemispherical limiting block, a fixing module is arranged at one end of each reset spring, and a tweezer auxiliary rod is arranged on one side of each fixing module; and the inner walls of one ends away from the tweezer main rods, of the tweezer auxiliary rods are connected, an observation assembly is arranged at one end away from each tweezer main rod, of the corresponding tweezer auxiliary rod, through the adjustable function of the length and angle of the extraction tweezers, rapid extraction of foreign matter in the nose and throat of a patient is achieved, operation is easy, andthe working efficiency is improved.

Description

technical field [0001] The invention mainly relates to the technical field of medical instruments, in particular to a combined instrument for extracting foreign matter in the nose and throat department. Background technique [0002] Nowadays, the extraction of foreign bodies in the nose and throat of patients is basically done by expanding the nose and throat cavity through the expansion arm, and then trying to extract it with different tweezers. The operation process is very complicated, wastes a lot of time, and reduces the treatment efficiency. , which also increases the difficulty of extraction. [0003] In the existing foreign body extraction combined instrument for nose and throat, for example, in the technical structure of the application document CN200920270041.7, it includes a peep hole and an expansion arm, which is characterized in that a slender clip is fixed on the upper side of the peep hole. The limitation is large, the operation is inconvenient, and it canno...

[0003] In the existing foreign body extraction combined instrument for nose and throat, for example, in the technical structure of the application document CN200920270041.7, it includes a peep hole and an expansion arm, which is characterized in that a slender clip is fixed on the upper side of the peep hole. The limitations are large, the operation is inconvenient, and it cannot be precisely controlled. Based on this, we need to develop a combination device that is easy to operate, simple in structure, and universally applicable.
