Description
Technical field
The utility model relates to a kind of unloading instruments of Nuss operation support frame.
Background technique
Chonechondrosternon Nuss art formula is Virginia, USA Children ' s HospitalofKing ' in 1998
A kind of Minimally Invasive Surgery with hand Pectus excavatum of the Dr. DonaldNuss research and development of sDaughters, method is simple, postoperative
Significant effect not only corrects breastbone and rib cage position, there is full thorax, improves cardio-pulmonary function, and the preceding wall of the chest does not have notch,
It cuts without rib reseclion and pectoralis major, is received by the doctor of countries in the world and patient rapidly.By 10 years continuously improve,
Now have become the standard art formula of chonechondrosternon treatment.It is considered as within 6 12 years old the best opportunity of Nuss operative correction chonechondrosternon.It should
Operation is the support frame in thoracoscope guiding menisectomy implantation moulding, and correcting breastbone and rib cage recess, support frame need to generally stay
Setting internal 2 years or more can just remove.The support mainly includes the arc NUSS main steel plate of titanium alloy material and in patient
The fixed plate of fixed main steel plate at two frame timbers, when carrying out Nuss operation, it is necessary first to which traditional NUSS main steel plate is passed through modeling
Clamp or bending machine are by its bending camber, by NUSS main steel plate, after operation mouth insertion human body, then fixed plate of taking makes
The both ends of NUSS main steel plate are inserted into respectively in the card slot of two fixed plates, and fixed plate is then sewn to trouble with operation suture thread again
On the periosteum of person；When removing support frame after 2 years, the cutting operation mouth at the fixed plate of human body, it is necessary first to first by card slot card
Fixed plate on main steel plate is removed from main steel plate, is needed to slide position of the fixed plate with respect to main steel plate, is made it from main steel plate
End take off, however because main steel plate and fixed plate with indwelling human body for many years, position is fixed with opposite human body, it is desirable to pass through one
A slight surgical wound slides fixed plate from main steel plate, and process is not easy very much, and doctor passes through a hand in the prior art
Fixed plate is clamped through surgical wound using pliers or instrument, another hand penetrates surgical wound using another pliers or instrument
Main steel plate is stabilized, and then firmly dragging slides fixed plate from main steel plate end, needs to overcome the resistance of muscle, power
It is very big, and firmly when restricted due to, wound position small by wound etc. so that cannot be much smoother firmly, often drag
It is easy to slip pliers or instrument and main steel plate or fixed plate in the process, so that fixed block can slide meeting original position, again again again
Firmly, until fixed plate is detached from from main steel plate, which is directly influenced by feel, generally requires by multiple effort
Fixed plate could be detached from from main steel plate, operation repeatedly not only aggravates the pain of sufferer, and it is a large amount of also to expend medical staff
Energy, the efficiency of operation is very low；It is used to slide fixed plate from the end of main steel plate there is no a dedicated instrument at present
Under.Therefore a medical instrument for enabling to fixed block to be easy to remove is provided, it is urgently to be resolved becomes those skilled in the art
Technical problem.
