Description
Technical Field
The invention relates to a medical apparatus, in particular to an annular ladle joint stirring clamp for resetting an annular ladle joint.
Background
When a patient is subjected to neck trauma, the patient can cause dislocation of the ladle joint, the most common symptom of the dislocation of the ladle joint is hoarseness, and then the patient has suffocation, shortness of breath, uncomfortable throat, borborygmus, and tired pronunciation, and serious patients can have dysphagia and choking by drinking water. Medical staff can easily cause dislocation of the annular bowl joint after the inner trachea cannula is anesthetized or the gastric tube is inserted, and medical disputes are easily caused.
The synovial joint is composed of joint cavity, fibrous capsule and synovial layer. The arytenoid cartilage has irregular surface morphology, nearly like a triangular pyramid, most of the laryngeal internal muscles start to stop at the cartilage, and the cartilage base is triangular and is connected with the cricoid cartilage to form the cricoid joint.
The existing restoration of the ladle joint is replaced by other forceps, such as restoration of the ladle joint by fishbone forceps, laryngeal forceps and the like, the ends of the forceps are smooth planes and have poor anastomosis with the irregular ladle cartilage surface, the forceps apply force to the ladle cartilage when in stirring, the forceps ends and the ladle cartilage are easy to slip off, the restoration effect is seriously affected, and mucous membrane damage on the surface of the ladle joint is easily caused.
Disclosure of Invention
The invention aims to provide the stirring pliers for the annular ladle joint, which are more anastomotic with the contact surface of the ladle-shaped cartilage, are more stable in contact, have better annular ladle joint resetting effect, are shorter in annular ladle joint resetting time and can not damage the annular ladle joint.
