Tracheal automatic spreader

Abstract

The invention discloses an automatic distraction device for the trachea. The automatic distraction device comprises a left distraction arm, a right distraction arm, a left tong head and a right tong head, and is characterized in that an automatic distraction apparatus is arranged at the rear end of the left distraction arm and the rear end of the right distraction arm and comprises a handle, a motor seat, a rotary nut, a rotary lead screw, an outer support, an inner support, inner arms, outer arms, a stepping motor and a control system, the lower end of the handle is fixedly connected with the outer support, the stepping motor is fixedly connected with the rotary nut, a threaded hole is formed in the center of the outer support, the outer arms are arranged at the two ends of the outer support respectively, the end of one outer arm is fixedly connected with the left distraction arm, the end of the other outer arm at the other end is fixedly connected with the right distraction arm, the rotary lead screw penetrates through the threaded hole in the outer support, the upper portion of the rotary lead screw is in threaded connection with the rotary nut, the lower end of the rotary lead screw is connected with the inner support, inner arms are arranged at the two ends of the inner support respectively, the upper ends of the inner arms are hinged to the inner support, and the lower ends of the inner arms are hinged to the middles of the outer arms through hinge shafts. The automatic distraction device has the advantages that the structure is novel, the first-aid efficiency is high, sputum suction is convenient, and the illumination effect is good.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an automatic trachea expander. Background technique [0002] Clinical tracheotomy is an effective first-aid measure for contact with airway obstruction, and it is an emergency operation to save the patient's life. In the past, the conventional tracheotomy method was to cut the skin, subcutaneous tissue, fascia, muscle, trachea, and then the trachea layer by layer. Internal intubation takes a long time to operate, causing great damage and pain to the patient, and sometimes delaying the treatment. In order to solve the above-mentioned technical problems, CN102462518 discloses a tracheotomy clamp type spreader, which is provided with a spreader arm with a fixed central axis, a handle and a hand ring, and the spreader arm is provided with a spreader arc arm, a curved Mouth-shaped jaws and U-shaped arc-shaped hooks, self-locking pieces with snapping grooves between the hand...

AI Technical Summary

Problems solved by technology

In clinical use, the operator holds the instrument and rotates the wrist along the long axis of the forearm. When pulling the tissue, the U-shaped arc-shaped hook is placed in the tissue gap, and the two self-locking pieces are occluded and fixed. When the anterior muscles of the seat neck are separated bluntly, the wrist rotates 180 degrees along the long axis of the forearm, and the two stretching arms drive the curved jaws to stretch the tissue, alternately separating from the ordinary vascular forceps. When dealing with tumors in the trachea and in emergency situations where it is not possible to suture the skin of the neck incision and the cartilage ring of the ipsilateral trachea, two spreading arms are usually used to drive the curved mouth-shaped jaws to spread the tissue, and a shadowless lamp is used for lighting. There is sputum and blood in the trachea The assistant doctor holds the sputum suction device to suck out the sputum and blood in the trachea. The substantial disadvantage is that after the trachea is cut, the shadowless lamp can only illuminate the outer shape of the trachea and cannot go deep into the inside of the trachea. The internal condition cannot be seen clearly, which affects the efficiency of first aid and wastes manpower
