Percutaneous rotator for tracheotomies

Abstract

The invention discloses a percutaneous rotator for tracheotomies. The percutaneous rotator for the tracheotomies is composed of a rotating handle and a percutaneous rotator body is composed of a smooth portion and a threaded portion at the front end, and the outer surface of the threaded portion is coated with a superlubric coating; the rotating handle is in a shape of four pieces and is provided with anti-slipping grooves. According to the percutaneous rotator for the tracheotomies, hydrophilic high polymer is organically combined to the surface of the threaded portion of the percutaneous rotator body through the superlubric surface decoration technology; the hydrophilic high polymer of the superlubric coating can achieve superlubric effects after getting wet to reduce the percutaneous friction force around an incision and to have compressing effects on surrounding tissues, thereby avoiding excessive bleeding, facilitating operation and effectively relieving pains of a patient; meanwhile, the rotating handle of the percutaneous rotator is in the four-piece shape, which accords body human mechanics, facilities of fore exertion of fingers by doctors or medical workers, smoothens rotary thrusting and facilitating rotary-cutting operations.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a percutaneous rotator for tracheotomy. Background technique [0002] The percutaneous rotary cutter for tracheotomy is a necessary medical instrument for the hospital to perform tracheotomy for critically ill patients. The front end of the traditional percutaneous rotary cutter is a threaded part. During tracheotomy, the friction between the percutaneous rotary cutter and the skin tissue at the incision is large, causing great damage to the surrounding skin tissue, and it is easy to cause a large amount of bleeding, causing serious harm to the patient. At the same time, postoperative complications increase, the cost of nursing is high, and it also brings a lot of inconvenience to doctors and nurses. Moreover, the end of the traditional percutaneous rotary cutter is a round handle, which is not conducive to finger force and difficult to rotate and advance. Contents of the inv...
