Abstract
The utility model relates to an adjustable patella claw belonging to a medical appliance, which comprises fixed claws which are symmetrically arranged and is characterized in that the patella claw is a symmetrical two-body type structure, tilting connecting edges are respectively arranged on the abutting joint of the two parts, corresponding connecting fixed holes are arranged on the two connecting edges, screws are traversed through the connecting fixed holes, and fixed screw caps are assembled on the screws. The two-body type structure can adjust the degree of the dimension and the strength of the pressure, the fixing effect is good, and the patella claw can reduce the manufacturing cost and use cost.
Description
Technical field
This utility model relates to a kind of scalable patella claw, belongs to medical apparatus and instruments.
Background technology
Need to use patella claw in treatment in the Patella fracture, the patella claw of using clinically realizes being out of shape adjustment by memorial alloy for the overall structure of the integral type made with expensive memorial alloy at present, has following problem:
(1) whole stereotyped structure, size dimension is fixed, and model selects face narrow, should select accurate suitable dimension to the patella of different sizes, and this makes troubles to manufacturer and use.
Insecure when (2) being fixed with, hollow can appear, influence fixed effect.
(3) intensity of pressure is not enough, is prone to the patella claw displacement, comes off, and causes fixing failure.
(4) memorial alloy price height causes manufacturing cost and use cost to improve.
The utility model content
The purpose of this utility model is to provide a kind of scalable patella claw, is two style structure, can regulate the size and the intensity of pressure, good fixing effect, and can reduce manufacturing cost and use cost.
Scalable patella claw described in the utility model has symmetrically arranged fixed claw, is symmetrical expression two body structures, two parts joint is respectively equipped with the fillet of perk, two fillets are provided with the corresponding hole that is connected and fixed, and are connected and fixed and are coated with screw in the hole, are fitted with hold-doun nut on the screw.
This utility model is designed to two style structure, can regulate size dimension and clamping compresses intensity by screw, adaptability is good, give to make and use and all bring convenience, clamping is firm, no hollow phenomenon is selected suitable grip strength, avoids the patella claw displacement, comes off, good fixing effect, and, because be two body structures, needn't leave no choice but use memorial alloy to make, can directly use titanium alloy even stainless steel material to make all can, can reduce manufacturing cost and use cost greatly, relieve patient ' s burden is beneficial to and promotes the use of.
Description of drawings
Fig. 1, this utility model one example structure sketch map.
Among the figure: 1, fixed claw 2, fillet 3, screw.
The specific embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, scalable patella claw described in the utility model, symmetrically arranged fixed claw 1 is arranged, be symmetrical expression two body structures, two parts joint is respectively equipped with the fillet 2 of perk, two fillets 2 are provided with the corresponding hole that is connected and fixed, and are connected and fixed and are coated with screw 3 in the hole, are fitted with hold-doun nut on the screw 3.
Carry out size dimension by screw 3 during use and regulate, after size is suitable, fixed by hold-doun nut, flexible and convenient operation is easy to control clamping and compresses intensity, obtains good fixed effect.
