Description
Technical field
The utility model is related to the technical field of medical instrument, particularly a kind of hook ulna far-end locking synthetisms
Plate.
Background technology
Ulna fracture of distal is often referred to the fracture within the 5cm of ulna distal end, including processus styloideus ulnae, head of ulna, ulna neck and
The backbone of part lower 1/3.The destruction of ulna distal end anatomical structure directly results in distal radioulnar ioint, triangular fiber cartilage and interosseous membrane
Destruction, so as to seriously affect the functional rehabilitation of wrist and forearm.Thus, the stability of ulna determines distal radioulnar ioint with before
The stabilization of arm spinfunction.It is special due to ulna distal end anatomical structure so that this position is resetted after fracturing with being consolidated
It is fixed also just to become more difficult.It is difficult to grasp elasticity for fixed outside traditional plintlet, gypsum, tension worries that iliacus film is comprehensive
The generations such as simulator sickness and pressure sore, excessively pine and easily increase displacement fracture possibility and lead to treatment failure.It is now to advocate in open reduction more
It is fixed, anti-rotational, fixed not firm, easy increase pin hole excitation and infection risk are fixed from Kirschner wire.Because ulna distal end is soft
Tissue coverage is less, and the thickness and anatomic form requirement to bone plate are high, and the miniplate at other existing positions is often
It is difficult to meet the needs of ulna fracture of distal.In addition, ulna fracture of distal is often fractured close to cubit joint and distal radioulnar ioint
It crushing again, existing general steel plate, which is fixed in fixing-stable intensity, to be also relatively difficult to meet clinical and increase fixed difficulty,
Often auxiliary gypsum is fixed and delay feature is taken exercise, and causes joint easily stiff.
To solve the above-mentioned problems, Chinese patent CN 203506858U disclose a kind of for the interior of ulna fracture of distal
Including a pair of of arc shaped hook wing, when being fixed in ulnar fracture, ring is carried out by the arc shaped hook wing by fixed plate for proximal ulna protrusion
Holding-solid is determined, and it is removably to be connected with each other to disclose between metallic plate and camber hook wing plate, and the mounting hole on its each plate
Center location is respectively positioned on fixed plate center line.It can be seen that although this scheme reduces the difficulty of clinical operation to a certain extent
Degree, still, encircling type fixed form are unfavorable for stablizing for fixed plate and fix, and are removable between metallic plate and camber hook wing plate
The interconnection unloaded, since fixed board size is smaller, the metallic plate and the production technology of the arc shaped hook wing being removably connected with each other
Upper relatively difficult, production difficulty is big, and production cost is high.Mounting hole center location on its each plate is respectively positioned on fixed plate center line, no
Conducive to being bonded for fixed plate and ulna.
Utility model content
The technical problems to be solved in the utility model is：In order to solve the ring of the internal fixation plate of existing ulna fracture of distal
The stable fixation that formula fixed form is unfavorable for fixed plate is embraced, is that dismountable phase interconnects between metallic plate and camber hook wing plate
It connects, it is relatively difficult on the metallic plate and the production technology of the arc shaped hook wing being removably connected with each other since fixed board size is smaller,
The problem of production difficulty is big, and production cost is high, the utility model provide a kind of hook ulna far-end locking bone plate, head
Sharp hook can effectively firmly grasp ulna bone protrusion, formed and effectively fixed, and improve the fixed stably solidity of bone plate, meanwhile,
The bone plate of the application is integrally formed, and simple production process fundamentally reduces production cost.
Technical solution is used by the utility model solves its technical problem：A kind of hook ulna far-end locking synthetism
Plate, including：Integrally formed lockplate proximal end, lockplate distal end and the locking for connecting lockplate proximal end and lockplate distal end
Plate plate body, the lockplate proximal end integrated molding are useful for the head point hook of promptly bone protrusion, the lockplate proximal end
Several mounting holes are equipped with lockplate distal end.
Specifically, the direction of above-mentioned head point hook is identical with the direction of straight line where ulna.It can ensure head point hook pair
The force direction of ulna is consistent with straight line where ulna, has higher stability.
Specifically, at least one locking compress hole is additionally provided on locking bone fracture plate.
Specifically, above-mentioned locking compress hole is arranged on lockplate plate.
Specifically, above-mentioned lockplate proximal end is set there are two mounting hole.
Specifically, the center of circle of above-mentioned two mounting hole is located at locking bone fracture plate center line both sides respectively.This setting, Ke Yitong
Crossing screw drives bone plate to be bonded with ulna in the holding direction of ulna, makes whole more firm.
Specifically, above-mentioned lockplate proximal end is additionally provided with the notch bent convenient for lockplate proximal end.
Specifically, locking bone fracture plate has a synthetism face contacted with ulna, the sky in the synthetism face of the lockplate proximal end
Between geometric shape match with proximal ulna protrusion and proximal ulna configuration of surface, the space in the synthetism face of the lockplate distal end
Geometric shape matches with ulna distal surface form, and the space geometry form and ulna in the synthetism face of the lockplate plate body are near
Ulnar surface form between end and ulna distal end matches.
The beneficial effects of the utility model are：
The utility model provides a kind of hook ulna far-end locking bone plate, and head point hook can effectively firmly grasp ruler
Bone bone protrusion is formed and is effectively fixed, and improves the fixed stably solidity of bone plate, meanwhile, the bone plate of the application is integrated
Molding, simple production process fundamentally reduce production cost.
