Abstract

The utility model introduces a compression U-shaped bone plate which is composed of a bone plate body and a transverse arm. The utility model is characterized in that a pressing hole which is in a slop along the bone plate body of the longitudinal direction is arranged on the bone plate body, and a group of perspective observation grooves are arranged on a pair of intermediate transverse arms. The bone plate has the advantages that the mutual pressurization of the fracture end can be effectively promoted, and the primary healing rate is enhanced. Simultaneously, the healing status of the fractuer position can be observed in time through the perspective observation groove, and the compression U-shaped bone plate is convenient for the succeeding treatment. The utility model has the advantages of simple structure and easy use.

Description

A kind of pressurization U type blade plate

This utility model relates to a kind of pressurization U type blade plate, belongs to the bone injury fixture class in medical mechanical domain's part.

U type blade plate is the fixation device that present orthopedics department patient uses always, because its effective apparatus that has become the cannon born fractures simple in structure, easy to use; But because structural limitation, the one, can't understand the healing state of fracture site easily; The 2nd, promoting fracture " first phase " healing rate, preventing the fracture displacement that it is slightly not enough to guarantee that fracture end is stablized the aspect.

The purpose of the present utility model: aim to provide a kind of U type blade plate of new construction, wish that it can prevent the displacement of fracturing effectively, guarantee the stable of fracture end; Can under not demolition blade plate condition, observe simultaneously the healing state of fracture site again effectively.

This pressurization U type blade plate is made up of blade plate main body (1) and transverse arm (2), it is characterized in that being provided with one and vertically be the pressurization hole (3) of slope along the blade plate main body on blade plate main body (1); Have one group of fluoroscopic observation groove (4) on the described a pair of middle transverse arm (2), described blade plate main body (1) is transitional attenuate shape with the arm end of transverse arm (2) simultaneously.

This pressurization U type blade plate according to above conceptual design, compare with at present general plain edition blade plate, its advantage one is that fracture end is pressurizeed mutually, and it is good to reach fracture " first phase " healing, make fracture end stablize, be difficult for being shifted, more help patient's early function and recover; Its two, can be beneficial to take the successive treatment measure by the timely fluoroscopic observation of the open recess of middle transverse arm to the healing state of fracture.

Accompanying drawing 1 is this utility model structural representation;

Accompanying drawing 2 is that the AA of accompanying drawing 1 is to cutaway view;

Further describe this utility model below in conjunction with accompanying drawing, and provide embodiment.

Pressurization U type blade plate shown in the figure is a kind of improvement to existing plain edition blade plate, mainly is pressurization hole (3) is set on blade plate main body (1), and the vertical impulse face in this pressurization hole is a domatic; Simultaneously again with middle transverse arm that blade plate main body (1) links to each other on open one group of symmetric observation groove (4).Just because of these 2 improvement, make this pressurization U type blade plate that is applicable to the cannon born fracture, played the effect that fracture bone plate does not have.When it is used in the cannon born fracture site, transverse arm (2) is facing to fracture boundary near interface in the middle of making, with steel nail itself and fracture site lower end are being fixed, and on the basis of carrying out reattachment surgery, in pressurization hole (3), be screwed into screw, because the effect of slope, one that makes that the blade plate main body (1) of fracture lower end is subjected to that the inclined-plane produces to upper pulling force, thereby the lower end cannon born of having fractured and upper end can very closely be adjacent to naturally can not produce displacement or gap, then in two other screw of blade plate main body (1), be screwed into screw again, guarantee finally that thus synthetism is in good condition.

Fluoroscopic observation groove (4) in the middle of this blade plate main body (1) on the transverse arm (2), be mainly used in the union of fracture state of checking, when originally using the plain edition blade plate, because metallic plate is to the deadening of X-ray, thereby can't detect the healing state of fracture, and adopt the pressurization U type blade plate of this fluted (4), then can show the healing state of fracture more effectively, so that the doctor can do anaphase work well with suiting the remedy to the case.

Claims

1, a kind of pressurization U type blade plate is made up of blade plate main body (1) and transverse arm (2), it is characterized in that being provided with one and vertically be the pressurization hole (3) of slope along the blade plate main body on blade plate main body (1); Described one is opposite to and has one group on the transverse arm (2) in the middle of the blade plate main body and observe groove (4); Described blade plate main body (1) is transitional attenuate shape with the arm end of transverse arm (2) simultaneously.
