Description
Technical field
The present invention relates to the field of medical instrument technology, are related specifically to a kind of device for endoscopic thyroid drag hook.
Background technique
In recent years, in the surgical intervention field of thyroid disease, device for endoscopic thyroid surgery is because of the small beautiful hidden, art of its notch
Neck does not have the advantages that notch insane trace afterwards, is at home and abroad gradually applied to clinic.In conventional open thyroid operation, operating field
Appear very crucial, for that purpose it is necessary to using drag hook by be located at thyroid gland in front of Anterior jugular muscles pull open, sometimes even need by
Anterior jugular muscles detachment is sufficiently to expose thyroid gland.But in the sub- art of hysteroscope, conventional goitre retractor volume is excessive and can not make
With needing to increase the sub- art notch of more hysteroscopes if using hysteroscope sub- art pincers traction Anterior jugular muscles, and in operation
Instrument can the shield portions hysteroscope visual field, influence patient's operation: it is limited and can not move then to appear effect with silk thread traction muscle group
Pull position.But existing cavity mirror thyroid operation retractor still has that hysteroscope field range is small, flexibility is poor, uses not side
Just the shortcomings that.
Summary of the invention
The main object of the present invention is to propose a kind of device for endoscopic thyroid drag hook, it is intended to solve hysteroscope visual field model in the prior art
