Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a cricothyroid membrane cutting device; and more particularly to a balloon pressure indicating cricothyroid dissection kit (or device) for use in a cricothyroid dissection.
Background
The cricothyroid membrane is located between the cricoid cartilage and the thyroid cartilage, is a conical elastic fibrous connective tissue membrane, and is a part of the elastic cone in front of the elastic diaphragm of the larynx. The laryngeal elastic membrane is located on the deep surface of the mucous membrane of the laryngeal cavity, belongs to a connective tissue membrane containing elastic fibers, is divided into an upper part and a lower part by a laryngeal chamber, the upper part is called a square membrane, the lower part is called an elastic cone, and the elastic cone starts from the lower part of the inner surface of the horn of the thyroid cartilage and is attached to the inner side of the upper edge of the cricoid cartilage in a fan shape downwards. The anterior middle part of the elastic cone is attached between the lower edge of the thyroid cartilage and the upper edge of the cricoid cartilage arch and is called the cricothyroid membrane, the thickened part at the center is called the middle ligament of the cricothyroid membrane, and when the cricothyroid membrane incision or puncture is performed, the cricothyroid membrane and the middle ligament of the cricothyroid membrane are mainly incised.
Thyrocricocentesis or incision is a commonly used first-aid technique in otolaryngology and is widely applied clinically; when acute laryngeal obstruction occurs, it can establish an artificial respiration channel in time and supply oxygen, suck phlegm or intratracheal therapeutic drugs and the like through the channel.
In contrast to thyrocricocentesis, a thyrocricocentesis requires a transverse cervical incision at the level of the thyrocricoid, with a single incision of skin, subcutaneous tissue and platysma, usually 4-5 cm in length. After the ring nail film is cut by the knife tip, the finger is used for pressing the ring nail film stoma to prevent the hemostatic liquid from entering the trachea, the tracheal catheter is inserted through the ring nail film stoma, and the cuff of the tracheal catheter is inflated to prevent blood from entering the lower respiratory tract, so that artificial respiration or mechanical assisted respiration can be performed.
However, since there is no special clinical incision instrument, it has been reported that incision is performed with a scalpel in many cases. However, it is difficult to control the incision width using a scalpel, the laryngeal tube is not fixed well, and the anterior cervical skin slides to both sides, thereby damaging the cricoid cartilage and its adjacent soft tissues, and also easily causing vascular or nerve damage. In addition, the operation is required to be carried out by a doctor specialized in otolaryngology, and the first-line clinical rescue of a patient is easy to delay the rescue opportunity, so that the clinical application is relatively limited. More importantly, the scalpel is an all-metal product and belongs to an invasive treatment means, and if the disinfection measure is not in place, the treatment environment is not clean, or the autoimmune system of a patient is incomplete, the possibility of bacterial infection caused by pathogen transmission exists. It has been shown that approximately 15-25% of patients undergoing a cricothyroid procedure develop various complications from infection.
Chinese utility model patent CN2635034Y discloses a quick cutter of cricothyroid membrane, and it includes that cross hinge connects two fixed blade heads and the double knives frame of handle is taken to the other end to constitute, and the cutting edge of blade head is outside, is convenient for insert and open the incision, cuts the width according to width limiting device and masters easily, guarantees that the inside and outside unanimity of notched width. However, in this patent, the cricothyroid membrane is incised with a knife edge, which causes defects such as varied incision sizes, excessive bleeding in incisions, and complicated operation. Moreover, the above described quick-cutter is still prone to residual bacteria at the blade edge and blade.
Therefore, in addition to the conventional clinical instrument disinfection process and the wrapping antibacterial composite membrane which are generally adopted in hospitals, the improvement of the incision device itself is needed to endow the incision device with antibacterial performance, and the incision device is simple, convenient and quick in disinfection and can still meet clinical requirements after being repeatedly used for many times.
