Abstract
This utility model is a patella restitution plier belonging to surgical operation appliance, consisting of a moveable claw and a fixed claw which are hinged into a whole. The handles of the moveable and fixed claws are connected through the jaw adjusting the movement of the device. On the operating ends of the two claws, two quadrangular clamping plates are set matched each other; and the two clamping plates both are 1cm to 1.5cm long and 0.5cm to 1cm wide, meanwhile bending into certain radian in the same direction. Compared with other technologies at present, this pair of new and practical patella restitution pliers has the following advantages: strong clamping power, small deviation in restitution, convenience for operating, etc., and can be widely used in restitution operations in case of fracture of patella.
Description
Technical field
This utility model relates to the surgical operating instrument field, especially a kind of patella reduction pincers that are used for the Patella fracture reduction.
Background technology
At present do not have special-purpose reduction pincers for the reduction of Patella fracture clinically, also just adopt towel forceps to replace.But towel forceps is because tong head is limit, and not only clamping dynamics is big inadequately, and is difficult to make patella reduction plane to reach the requirement of 2 millimeters reduction errors.
Summary of the invention
Technical assignment of the present utility model is to provide a kind of patella reduction pincers at above-mentioned deficiency of the prior art, and this patella reduction tonger has characteristics such as easy to use, that the reduction error is little.
The technical scheme that its technical problem that solves this utility model adopts is: patella reduction pincers, comprise the moving caliper and the fixed caliper that are hinged to one, the handheld terminal of moving caliper and fixed caliper flexibly connects by the adjusting device of dehiscing, be characterized in being provided with involutory tetragon holding piece mutually in the working end of moving caliper and fixed caliper, the length of two holding pieces is 1-1.5cm, width is 0.5-1cm, and bending has certain radian in the same way.
The crooked radian of moving caliper end holding piece is greater than the crooked radian of fixed caliper working end holding piece.
Patella reduction pincers of the present utility model are provided with the tetragon holding piece that size and radian and patella adapt at the characteristics of patella structure in the working end.Enough big clamping dynamics can be provided in the reduction process, and can reduce the reduction error effectively, make operation process safer reliable, reduce the incidence rate of postoperative patellofemoral arthritis.
Description of drawings
The specific embodiment
Explain below with reference to Figure of description patella reduction of the present utility model pincers being done.
Shown in accompanying drawing 1-3, patella reduction pincers of the present utility model are made of moving caliper 1, fixed caliper 2, the adjusting device of dehiscing 3 and holding piece 4,5.Moving caliper 1 is hinged by hinge 6 with fixed caliper 2 and is in the same place, and its handheld terminal flexibly connects by the adjusting device 3 of dehiscing.Involutory square holding piece 4,5 is separately fixed at the working end of moving caliper and fixed caliper mutually.Two holding pieces 4,5 bending in the same way have certain radian, and the crooked radian that is arranged on the holding piece 4 of moving caliper 1 end is slightly larger than the crooked radian of fixed caliper 2 end holding pieces 5.The length of two holding pieces 4,5 is 1.5cm, width is 0.8cm.
It is very simple and convenient that patella reduction of the present utility model clamps its processing and fabricating, and the processing method processing and fabricating according to general medical calm shown in the by specification accompanying drawing gets final product.
Except that the described technical characterictic of description, be the known technology of those skilled in the art.
Claims (2)
1, patella reduction pincers, comprise the moving caliper and the fixed caliper that are hinged to one, the handheld terminal of moving caliper and fixed caliper flexibly connects by the adjusting device of dehiscing, it is characterized in that being provided with involutory tetragon holding piece mutually in the working end of moving caliper and fixed caliper, the length of two holding pieces is 1-1.5cm, width is 0.5-1cm, and bends to certain radian in the same way.
2, patella reduction pincers according to claim 1 is characterized in that the crooked radian of the crooked radian of moving caliper end holding piece greater than fixed caliper working end holding piece.
