Description
Technical field
The utility model relates to the field of medical instrument technology, can increase surgical procedure more particularly, to one kind with Telescopic rotating
The novel armpit approach cavity mirror thyroid operation retractor in space and field range.
Background technique
For conventional open thyroid operation usually because doing row notch in neck, postoperative neck scar pimple hyperplasia influences beauty
See, perplex the life of patient, with minimally invasive theory continuous expansion extensively, the update of laparoscopic operation method and instrument it is continuous into
Step, neck are gradually appeared without the operation of keloid.The development that past more than ten years device for endoscopic thyroid surgery is advanced by leaps and bounds,
There are various art formulas, such as full breast areola approach, armpit mammary areola pathway, single hole mammary areola pathway, armpit assisted laparoscope etc..Closely
It successively reports over year and performs the operation through axillary approach device for endoscopic thyroid single hole, use U-shaped in the operation of axillary approach device for endoscopic thyroid single hole
The drag hook of shape is by epidermal tissue's pull-up of the armpit of patient to neck.
China Patent Publication No. is that CN205379323 discloses a kind of goitre retractor with antiskid function, including draws
Bar and the first drag hook and the second drag hook that pull rod both ends are set, if the inner surface of first drag hook and the second drag hook is provided with
Convex grain is done, the first drag hook, the second drag hook and convex grain are made of one piece.In surgical procedure, it is attached that the second drag hook protrudes into patient's armpit
In close surgical aperture, the first drag hook is above mentioned, the second drag hook is by epidermal tissue's pull-up of the armpit of patient to neck, thus shape
At surgical procedure space, facilitates doctor to be inserted into surgical instrument and the surgical procedures such as shear, clamp, but human cuticular tissue
It is limited to pull up rise, causes surgical procedure narrow space, surgical procedure difficulty is larger, is easy to appear fault.
Summary of the invention
The utility model is the hardly possible of surgical procedure caused by order to overcome prior art armpit approach surgical procedure narrow space
Larger problem is spent, to provide one kind can expand armpit approach surgical procedure space, facilitate doctor is subsequent to be operated
