Description

A kind of Universal locking fracture bone plate

Technical field

It is the utility model relates to the field of medical instrument technology, in particular to a kind of to be connect for universal lock fixed in orthopaedics Bone plate.

Background technique

Clinically mainly it is made of lock screw and steel plate for fixedly locked bone plate system in orthopaedics, we term it Locking steel plate screw system.In locking steel plate screw system, the angle between lock screw and steel plate is preset.So And in order to enable the lock screw in implantation bone with optimal fixed effect, then requires lock screw must be in a specified direction It is implanted into bone.Since the skeletal shape between the different and Different Individual of fracture damaged portion has differences, in clinic In, this locking steel plate screw system is commonly present implantation direction set between lock screw and steel plate and best implantation The inconsistent contradiction in direction, leverages surgical effect, also reduces the success rate of operation.

Utility model content

To solve the above-mentioned problems, the purpose of the utility model is to provide a kind of Universal locking fracture bone plate, can make to lock Screw is determined to be most preferably implanted into direction implantation sclerotin, and is well fixed between lockplate, and various types of sclerotin are adapted to.

To achieve the above object, the utility model takes following technical scheme:

A kind of Universal locking fracture bone plate includes lockplate, has several lock holes on lockplate, and lock hole inner wall is equipped with more A arc fin encloses structure between these fins and goes out one in flower-shaped accommodating space.

Further, lock hole inner wall is set there are five arc fin, enclosed between these fins structure go out one be in plum blossom-shaped appearance Between emptying.

Further, the fin is structure as a whole with the lock hole, and the thickness of fin by edge to root gradually Increase.

Preferably, the upper and lower surfaces of the fin are in 70 ° and 45 ° of angle with horizontal axis respectively, and centre has Double thread.

Further, the lockplate is L shape or other design shapes.

The beneficial effects of the utility model are: the utility model Universal locking fracture bone plate structure is simple, can arbitrarily adjust Implantation direction between screw and lockplate, the screw diversification cooperated with the lock hole of Universal lock fixed board, universal lock synthetism The lockplate of plate has good adhesion, can preferably carry out the fixation of fracture site.

The flexibility that screw deviates the track of lock hole axis can be improved in the utility model Universal locking fracture bone plate, thus Allow the fixation of special fractures block, expansion screw angle provides a series of classification of fracture fixed selection, especially involves pass The fracture of nodal section can securely maintain to reset, and screw is avoided to enter articular cavity, be conducive to the functional rehabilitation of patient's early stage.

Specific embodiment

The possible state sample implementation of the utility model is only illustrated with embodiment below, however not to limit the utility model The scope to be protected, first give chat it is bright.

Referring to attached drawing 1-4, a kind of Universal locking fracture bone plate includes lockplate 1, has several lock holes 2, lock on lockplate 1 Determine 2 inner wall of hole and be equipped with multiple arcs fin 3, structure is enclosed between these fins 3 and goes out one in flower-shaped accommodating space.

2 inner wall of lock hole is set there are five arc fin 3, enclosed between these fins 3 structure go out one be in plum blossom-shaped accommodating space.

As shown in Figure 1 and Figure 2, it includes lockplate 1 that the utility model, which provides a kind of Universal locking fracture bone plate, on the lockplate 1 With several universal lock holes 2；As shown in Figure 3, Figure 4, which sets there are five arc fin 3 and double thread 5, It can be locked mutually with the screw thread of screw head, form the stable structure type of interference and mark off several specifications.This structure Form can be locked according to the special anatomical shape of bone, the position of adjusting screw in 360 ° of any directions, and The fixed angle formed of the angulation of any direction also has breakthrough, and no more than 15 ° of angulation is fixed.In addition, and lock hole The also no longer unification of the screw of cooperation can according to need the various forms of screws of selection, such as 3.5mm can be used in different size Lock screw and non-locking os integumentale screw and 5.0mm lock screw and non-locking os integumentale screw.Structure is enclosed between those fins 3 Out one be in plum blossom-shaped accommodating space 4.The accommodating space 4 for be placed in sclerotin screw pass through and with those fins 3 and double end spiral shell Line 5 fastens and fixation bone fracture plate.

As shown in Figure 3, Figure 4, which is structure as a whole with the lock hole, and the thickness of the fin 3 is by edge to root Portion is gradually increased.Preferably, the upper and lower surfaces of the fin 3 are in 70 ° and 45 ° of angle with horizontal axis respectively, intermediate There is double thread.

A kind of Universal locking fracture bone plate, each lock hole (nail hole) is able to achieve after screw screws and lock hole (nail hole) central axis 15 ° of angles of maximum.

As shown in Figure 1 and Figure 2, the lockplate 1 of the utility model is L shape or other design shapes, is adapted to various The fracture of type, itself has toughness, can be very good to be attached at bone.It uses undercut mark moulding, this can be made practical new Type Universal locking fracture bone plate can adapt to various soft tissue coverings and reduce the classification of fracture at position, for example enclose the position in joint.Lock Fixed board with bone face there is good matching to be bonded effect, not only provide the effect of reset for fracture, but also can generate and add to sclerite Pressure, very small for the variation influence of the shape of body, the time needed for such Rehabilitation can also be reduced.

Total described, the utility model Universal locking fracture bone plate has the advantage that

1, being arranged on fin and fin in the lock hole of lockplate has double thread, locks mutually with the screw thread of screw head It is fixed, it can be locked according to the special anatomical shape of bone, the position of adjusting screw in 360 ° of any directions；

2, screw can be fixed in the angulation of lock hole any direction, and angulation of the maximum no more than 15 ° is fixed, i.e. screw axis The maximum angle that line and locking axially bored line are formed is 15 °；

3, it with the screw also no longer unification of the lock hole of lockplate cooperation, can be needed to select different structure according to specification The screw of form, for example, different size can be used 3.5mm lock screw and non-locking os integumentale screw and 5.0mm lock screw and Non-locking os integumentale screw；

4, lockplate is designed as undercut mark moulding, can adapt it to the fracture class that various soft tissues coverings reduce positions Type, for example enclose the position in joint；

5, the structure type of lockplate has good adhesion, it is made with bone face to there is good matching to be bonded effect, Not only the effect of reset was provided for fracture, but also pressurization can be generated to sclerite, and accelerated the rehabilitation speed of patient；

6, the surfaces of revolution where the upper and lower surface of lock hole fin and its axis are in the angle of 70 ° and 45 ° respectively, and centre has Double thread can make screw when locking in this way, and what is be threadedly engaged is even closer, the locking of screw and fixed effect More preferably；

7, the upper and lower surface of each fin of lock hole is to be processed simultaneously, can guarantee five fins or more in this way The consistency of shape, then finish-milling double thread improve the cooperation precision of screw thread, further improve the fiting effect of screw thread, So that stability between screw, bone and Universal locking fracture bone plate three is more preferable, stationarity is more preferable.

The utility model is defined by the claim.But it is based on this, those skilled in the art can It, all should be within the main spirits and protection scope of the utility model to make various specifications obvious variation or change.
