Abstract
The utility model discloses an adjustable patella claw, which comprises two corresponding fixing claws. Each fixing claw comprises a fixed adjusting plate and a claw body connected to one end of the fixed adjusting plate, the inside of the fixed adjusting plate of one fixing claw is a hollow groove, the fixed adjusting plate of the other fixing claw rightly extends into the hollow groove and can retractably slide in the hollow groove, the fixed adjusting plate with the hollow groove is provided with a fixing screw, and one end of the fixing screw is rightly abutted onto the fixed adjusting plate extending into the hollow groove. As the patella claw includes the two fixing claws and is a split structure, the two fixing claws can be used for adjusting the size of the patella claw by means of mutual retraction of the fixed adjusting plates, the trouble that patella claws in different models are required to be selected clinically is omitted, and the adjustable patella claw is simple and convenient in operation and low in service cost.
Description
Technical field
This utility model relates to a kind of medical auxiliary apparatus, relates in particular to a kind of patella claw that is used for Patella fracture.
Background technology
Patella fracture is more common clinically, because of fracturing in the ankle, therefore recover the form of its former articular surface to greatest extent, strive making fracture anatomical reduction, articular surface is level and smooth, give firm internal fixation, the early ambulant knee joint, could maximum possible prevent and reduce generation as complication such as traumatic patellofemoral arthritis, ankylosises.Traditional internal fixation method has steel wire circular ligate, because of the tension band principle is owed firmly and do not met to fixation, can not the early ambulant knee joint, and easily cause the patella front side and separate, therefore easily cause the dislocation again of ankylosis and fracture clinically.At present, many clinically employing memorial alloy patella claw are fixed, memorial alloy has good ductility, the property reversed and flexible because of it, therefore, fixed effect is more satisfactory, but also has following problem: the one, and patella claw all is an integraty, size is non-adjustable, can only select suitable dimensions according to the shape of patella clinically, use cumbersome; The 2nd, the memorial alloy price is higher, certainly will increase manufacturing cost and use cost.
Summary of the invention
The purpose of this utility model is exactly the above problem at the patella claw existence of existing use, and a kind of adjustable patella claw is provided, and it can regulate size arbitrarily according to the form of patella, and is easy and simple to handle, and use cost is low.
The purpose of this utility model is achieved through the following technical solutions, this adjustable patella claw comprises two corresponding fixed claws, each fixed claw comprises the secured adjusted plate and is connected the corpus unguis of secured adjusted plate one end, the secured adjusted intralaminar part of a described fixed claw is a hollow groove, the secured adjusted plate of described another fixed claw just in time stretches in the hollow groove, and telescopic slide therein, the secured adjusted plate of described band hollow groove is provided with a hold-down screw, and hold-down screw one corrects and withstands on the secured adjusted plate that stretches into hollow groove.
During use,, utilize the flexible of two secured adjusted plates, regulate the size of patella claw, make its size that just in time is fit to patella according to size, the shape of patella, fix corpus unguis after, utilize hold-down screw with two firm being fixed together of secured adjusted plate.
The beneficial effects of the utility model: because patella claw is two fixed claws, be a minute body structure, two fixed claws can pass through the size of the mutual telescopic adjustment patella claw of secured adjusted plate, have saved the trouble of selecting the different model patella claw clinically, easy and simple to handle, use cost is low.
