Problems solved by technology

[0004] CN203424998U), this patented technology can install the blade on the cricothyroidotomy device, then utilize the blade to cut the patient's cricothyroid membrane, at last, fix the throat, the thumb and forefinger of the right hand clamp the clamp arm In the middle of the body, the ichthyosaurus muscle is close to the tiger's mouth plate at the upper end of the knife handle. The conical extension of the clamping part is perpendicular to the skin and pierces the cricothyroid membrane horizontally. Stop piercing when there is a feeling of falling. At this time, press the left hand The tail of the forceps arm stretches the clamping part, and after taking out the handle with the right hand, push the conical extension of the clamping part forward at 45° with the skin, so that 2 / 3 of the conical extension enters the trachea, and press the back of the forceps arm Stretch the clamping part and use the support adjustment plate to support and position, take the corresponding endotracheal intubation tube or metal catheter and insert it into the trachea along the stretched clamping part, but the cricothyrotomy device in this patent is used Assembly is required and time wasted in assembling the cricothyrotomy in the event of a patient requiring first aid, with issues with the blade being unstable

Abstract

The invention discloses a novel rapid cricothyroid membrane incision distractor, and belongs to the technical field of medical instruments, the novel rapid cricothyroid membrane incision distractor comprises supporting arms, connectors and a handle, one end of the handle is provided with a supporting head, the supporting head is composed of two supporting arms, and the two supporting arms are in damped rotational connection with the handle through the connectors. According to the distractor, a sliding block on one supporting arm is pushed, the sliding block drives a gear to rotate through a rack when sliding, a threaded rod can be driven to rotate when the gear rotates, a cutting knife can be driven to move towards the lower end of the supporting arm through a threaded pipe when the threaded rod rotates, when the cutting knife extends out of the supporting arms, the cutting knife can be used for cutting the cricothyroid membrane of a patient, so that the cricothyroid membrane of the patient is rapidly opened, after the cricothyroid membrane is opened, the cutting knife is retracted into the supporting arms, then the two supporting arms are inserted into an incision, then the two supporting arms are opened through the handle, and the patient can be subjected to intubation treatment.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel rapid cricothyroidotomy spreader. Background technique [0002] Since the casualty with respiratory obstruction can die from suffocation within a few minutes, quickly establishing an airway and keeping it unobstructed is an important means to rescue the respiratory obstructive casualty. Currently, there are mainly cricothyroidotomy or cricothyroidotomy clinically used for emergency rescue of respiratory obstruction. [0003] Chinese patent discloses a fast cricothyrotomy device. (authorized announcement number [0004] CN203424998U), the patented technology can install the blade on the cricothyroidotomy device, then utilize the blade to cut the patient's cricothyroid membrane, and finally, fix the throat, the thumb and forefinger of the right hand clamp the clamp arm In the middle part of the knife handle, the ichthyosaurus muscle is close to the tiger's mouth p...
