Description

Distal humerus carries on the back outer side band and supports universal lock steel plate

Technical field

This application involves bone surgery, in particular to a kind of distal humerus back outer side band supports universal lock steel plate.

Background technique

The principle of locking bone fracture plate osteopathy is to select corresponding locking bone fracture plate to place accordingly according to the fracture situation of patient Fracture site, steel plate and bone are fixed accordingly by lock screw, restore impaired portion with the self-healing function of bone Point, then consolidate and take out steel plate and screw after a certain period of time, so that patient is fully recovered.

The fracture of humerus situation of some patientss is more special, distal portion and bar portion multiple fracture, and conventional fixation is more difficult, causes Such patients surgery difficulty complexity and time are longer, and later period recovery effects are undesirable, and postoperative need to crouch for a long time of patient be lain, and be taken action It is inconvenient.

In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " installation ", " phase Even ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can To be mechanical connection, it is also possible to be electrically connected；It can be directly connected, can also can be indirectly connected through an intermediary Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood at this with concrete condition Concrete meaning in invention.

In conjunction with shown in Fig. 1-2, distal humerus carries on the back outer side band and supports universal lock steel plate, including lath-shaped plate body 100, 100 side of plate body is bonded humerus outer surface, and 100 head of plate body has protruded out the small hook 110 of rectangle, rectangle to side Small hook 110 extends to distal humerus back outside, and small 110 inner surface arc of the hook fitting distal humerus of rectangle carries on the back outer surface, long Rectangular 110 surface of small hook and 100 head surface of plate body are respectively arranged with multiple universal lock holes 120.Plate body 100 Head and tail portion are respectively arranged with kirschner pin hole 130.100 surface of plate body is uniformly distributed multiple threaded holes 140.Part or Whole threaded holes 140 are pressurization hole.The side both ends uniformly distributed fluted 150 of the fitting humerus of plate body 100.Groove 150 It is set between two adjacent screw holes 140.There are two universal lock holes 120 for small 110 surface of the hook setting of rectangle.It is each universal Lock hole 120 includes 4 semicircle minor thread teeth 121 around lopping.

The technical solution, plate body can be fixed on the outside of the back of distal humerus, laterally prolong on plate body head Stretching has the small hook of a rectangle, and entire head reverse side curved surface and bone are adapted, and the universal lock hole on all heads is universal design, In hole, surrounding is provided with four uniformly distributed semicircle minor thread teeth, and there are kirschner pin hole in head and tail portion, and reverse side is opened among two threaded holes There are symmetrical grooves.

Doctor selects corresponding steel plate (such as left and right, length etc.), early period and post-operative behaviour according to the fracture situation of patient Make as conventional locking steel plate operation, the difference is that operation mid-term operation, specific as follows:

1 plate body is placed on the suitable position of bone, and Kirschner wire is passed through plate body head by corresponding instrument The kirschner pin hole of portion and tail portion squeezes into bone, pre-fixes plate body and bone first once.

2 are fixed steel plate head using universal lock screw, and common locking structure is to the quality of instrument and doctor Operate more demanding, the direction that is screwed into of screw must be consistent with the threaded hole angle direction on steel plate, can often during surgery can A variety of factors are answered to cause angle inconsistent, screw and steel plate can be not fixed firmly if forcing to be screwed into gently, and it will cause steel for weight Plate and bone are not bonded or steel plate cracking, screw fracture, secondary fracture that is serious or even will cause bone.

And in the technical program, universal lock allows the angular compliance of screw and steel plate certain deviation, has reached drop The purpose of low operating difficulty, reason be to be surrounded by universal lock hole by multiple semicircle minor thread teeth, screw only need with Meaning, which overlaps two of them or three semicircle minor thread teeth, can realize fixation, allow for the certain deviation of fit angle.

Design has symmetrical groove between 3 plate body reverse side, two hole, is few pressure in order to reduce the contact area with bone Compel periosteum, plays the purpose for increasing blood fortune, while also mitigating steel plate weight.

The small hook of a rectangle that 4 plate body heads are laterally extended can extend on the outside of the back of distal humerus, arc Match with back outer arcuate, above there are two universal lock hole, enhance plate body head and the tergolateral fixation of humerus.

5 pull out the Kirschner wire of head and tail portion again after screw fixes.

It reduces the difficulty of operation and reduces operating time, patient's post-operative recovery effect is good, the time is fast.

It should be noted that, in this document, relational terms such as first and second and the like are used merely to a reality Body or operation are distinguished with another entity or operation, are deposited without necessarily requiring or implying between these entities or operation In any actual relationship or order or sequence.Moreover, the terms "include", "comprise" or its any other variant are intended to Non-exclusive inclusion, so that the process, method, article or equipment including a series of elements is not only wanted including those Element, but also including other elements that are not explicitly listed, or further include for this process, method, article or equipment Intrinsic element.In the absence of more restrictions, the element limited by sentence "including a ...", it is not excluded that There is also other identical elements in process, method, article or equipment including the element.

The above is only the specific embodiment of the application, it is noted that for the ordinary skill people of the art For member, under the premise of not departing from the application principle, several improvements and modifications can also be made, these improvements and modifications are also answered It is considered as the protection scope of the application.
