Description

Tracheotomy retractor of integrated thyroid isthmus lifting structure Technical Field The invention relates to the technical field of medical appliances, in particular to a tracheotomy retractor with an integrated thyroid isthmus lifting structure. Background Tracheotomy is an indispensable key operation in clinic, plays an important role in the fields of emergency rescue and severe treatment, is often used as a pre-operation to be carried out in advance in the operations of the oral cavity, the maxillofacial region and the throat, and creates a safe condition for the smooth development of a subsequent main operation, and the core of the operation is that 2-4 rings of the trachea are rapidly and accurately exposed and cut is completed, and the operation efficiency and the safety are directly related to the prognosis of a patient; the prior tracheotomy retractor is two independent metal retractors, a main cutter, a first aid and a second aid are needed to be matched during operation, and the first aid is needed to be used for pulling the retractor while exposing the visual field due to the lack of the second aid, so that the retractor has poor stability and insufficient pulling force, the operation time is prolonged, the risk of accidentally injuring peripheral blood vessels and nerves possibly caused by the offset of pulling positions is increased, in addition, the obese patients have the problems of thick neck fat accumulation, relatively short neck, small operation space, strong pulling resistance, obvious deep tracheal positions of the common patients (average depth is 2-3 cm) and the like, the traditional retractor cannot effectively expose tracheal rings, the incidence rate of complications such as mistaken cutting of the tracheal rings, bleeding after operation and the like is higher due to incomplete exposure, the thyroid canyon is usually positioned in front of 2-4 rings of the trachea, the anatomical position is caused by the fact that the tracheal canyon needs to be properly lifted or separated in the tracheotomy operation, the conventional retractor cannot conveniently and safely cut the upper thyroid canyon part of the patient, the soft tissues before the traction of the two sides is pulled, the tracheal canyon is difficult to expose the tracheal rings, and the patients are difficult to expose the oral rings, especially because of the oral canyon is difficult to expose, we propose a tracheotomy retractor of an integrated thyroid isthmus lifting structure. Disclosure of Invention In view of the above, the present invention provides a tracheotomy retractor of an integrated thyroid isthmus pulling structure, comprising a retractor body frame, a grip coupled to a rear side of the retractor body frame, a retractor arm assembly mounted on and protruding from the retractor body frame to a front side, and a pulling assembly protruding from the retractor body frame to both sides of the retractor arm assembly from the front side of the retractor body frame, the grip being operated to adjust an opening and closing degree of the retractor arm assembly. According to one aspect of the invention, the tracheotomy retractor of the integrated thyroid isthmus lifting structure further comprises a retractor fixing component which is arranged on the retractor main body frame and positioned at the tail of the grab handle, wherein the retractor fixing component comprises an arc-shaped rack plate and a locking piece, the arc-shaped rack plate is fixedly connected in a groove at one end of the retractor main body frame, which is close to the tail of the grab handle, the locking piece is provided with teeth and is movably connected in a groove at the other end of the retractor main body frame, which is close to the tail of the grab handle, and the teeth on the locking piece are meshed with the tooth grooves on the arc-shaped rack plate so as to fix the opening and closing positions of the retractor. According to one aspect of the invention, the pulling assembly comprises a barrel, a screw, a threaded sleeve, a fixing member and a pulling seat, wherein the screw and the threaded sleeve are installed in the barrel, the inner wall of the threaded sleeve is connected to the outer edge of the screw through threads, the outer wall of the threaded sleeve is in sliding connection with the inner wall of the barrel, the fixing member is connected to the front end of the threaded sleeve, and the pulling seat is movably connected with the fixing member on the opposite side, so that the pulling seat can rotate relative to the fixing member to enable the pulling seat to be lifted. According to one aspect of the invention, the cylinder of the lifting assembly is connected to the front side of the fulcrum in the middle of the main body frame of the drag hook, the rear side of the fulcrum is provided with a dial wheel, the dial wheel drives the screw to rotate so as to drive the threaded sleeve to move towards the front side, and anti-sk
