Description

Proximal ulna hook locked pressurized bone plate

Technical field

The utility model relates to the field of medical instrument technology more particularly to a kind of proximal ulna hook locking compress synthetisms Plate.

Background technique

In clinic, need to treat the fracture of olecroanon using the bone plate of proximal ulna, although at present clinically Have the bone plate for the treatment of olecranal fracture, but different journeys easily are caused to triceps muscle of arm tendon when treating olecranal fracture The destruction of degree, for example clinically common proximal ulna locking bone fracture plate is writing board shape now, without the design of similar point hook, Triceps muscle of arm tendon must be removed in fixing lock fixed board to be just capable of fixing, can also destroy capsula articularis cubiti, influence postoperative patient elbow pass Save the recovery of function.For another example a kind of hook ulna far-end locking bone plate and the patent No. disclosed in Patent No. CN207520190U A kind of ulna olecranon plate disclosed in CN201847763U, although such bone plate devises sharp hook structure, but its locking effect is simultaneously It is undesirable, it is unsatisfactory with being bonded for fibula.

Utility model content

The proximal ulna hook that the purpose of the utility model is to provide a kind of structures is simple, locking effect is good, stickiness is good Locked pressurized bone plate.

The utility model is achieved by the following technical solution: a kind of proximal ulna hook locked pressurized bone plate, packet A plate is included, the plate includes integrally formed horizontal part and hook part, and the horizontal part is evenly equipped with several locks along center line Determine threaded hole, the horizontal part offers a waist type long slot hole far from one end of hook part, and the horizontal part includes being integrally formed And first horizontal portion and the second horizontal part in same level, second horizontal part is far from hook part, first level There is bending section, the hook part includes the first hook part and the second hook part, the first hook part between portion and the second horizontal part And second have a U-shaped opening groove between hook part, first hook part or the second hook part include integrally formed bending Section and extended segment, the bending section are connect with horizontal part, and the extended segment extends to horizontal part far from one end of hook part, and prolongs It stretches section and tilts down setting.

In order to lock securely, uniformly distributed on the horizontal part there are five locking screw thread holes.

In the utility model another preferred embodiment, in order to improve the validity of fitting, the first hook part and second curved Hook portion does not use symmetrical structure, and the extended segment of first hook part and the second hook part is respectively to the center line of first horizontal portion Inside gather, and two extended segment Length discrepancies.

The beneficial effects of the utility model are: the level that the proximal ulna hook locked pressurized bone plate passes through special designing The mutual cooperation of portion and hook part can be realized accurate treatment, it can be achieved that locking and pressurization function, with the stickiness of ulna compared with Good, fixation is reliable, can prevent the rotation of proximal ulna fracture site, and reduce the destruction to tendon.
