Abstract
The utility model discloses an internal malleolus steel sheet fixing system, including fixed steel sheet of internal malleolus and pressurization locking screw, its characterized in that: the fixed steel sheet of internal malleolus includes straight section and bending section, and the anklebone shape is corresponding in its interior surface profile and the human body, at least one and pressurization locking screw complex pressurization locking hole have all been opened to straight section of the fixed steel sheet of internal malleolus and bending section, the downthehole internal thread that is provided with of pressurization locking, the pressurization locking screw includes screw rod and head, there is the screw of putting into that is used for screw in broken bone on the screw rod, pressurization locking screw head is provided with and pressurizes and lock hole complex locking screw thread. The internal malleolus steel sheet fixing system who has above -mentioned structure, the pressurization locking kong ke on the internal malleolus steel sheet squeezes into the pressurization locking screw, and this screw not only has tensile force, and it self can also lock on the steel sheet, and the stability that forms the three in one of nail, board and surface of bone is fixed.
Description
Technical field
The utility model relates to a kind of steel plate fixed system for internal malleolus.
Background technology
Internal malleolus is as a part for ankle-joint, plays important maintaining ankle cave form and ankle stabilityEffect. Fracture of medial malleolus can be divided into simple form and compound, and the latter refers to merge external malleolus, rear ankle or lower tibiofibulaCombined injuries etc., if treatment is not proper, can make a big impact to ankle joint function, and the later stage easily occursTraumatic ankle-joint osteoarthritis, causes the long-term pain of ankle-joint, ankle moving limited, serious shadowRing patients ' life quality. The type difference of fracture of medial malleolus, therapeutic scheme is also different. For simple nothingDisplacement fracture of medial malleolus, can take expectant treatment--plaster immobilization, but expectant treatment exists fracture secondaryDisplacement possibility; Conventionally need to perform the operation and control for simple shift-type fracture of medial malleolus and compound fracture of medial malleolusTreat to obtain anatomical reduction and strong fixing. Larger for sclerite in simple fracture of medial malleolus, canSelect hollow screw or Kirschner wire+needles combined with tension band to fix, for the less internal malleolus avulsion bone of scleriteFolding, cannot implement effectively to fix therefore adopt more because hollow screw may cause sclerite explosionKirschner wire and tension band are fixed. For complicated fracture of medial malleolus (fracture fragment is more than 2), treatment ratioMore difficult, no matter be that hollow screw is fixed, or fixing all can not the enforcement of Kirschner wire+needles combined with tension band separatedCut open and reset and strong fixing, and conventionally need auxiliary fixing 4-6 week of plaster slab, patient cannot be early stageCarry out ankle joint function reconditioning, the arthritic possibility of deuterogenesis's traumatic bone is large.
Utility model content
For the technical problem of above-mentioned existence, the utility model provides a kind of internal malleolus steel plate fixed system,Realize complicated fracture of medial malleolus anatomical reduction and strengthen fixing.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of internal malleolus steelPlate fixation system, comprises internal malleolus fixation steel plate and locking and pressurizing screw; It is characterized in that: in describedAnkle fixation steel plate comprises flat segments and bending section, and its inner surface configuration is with corresponding with human body medial ankle bone shape;Described internal malleolus fixation steel plate flat segments and bending section all have at least one and locking and pressurizing screw fitLocking and pressurizing hole; Locking and pressurizing is provided with internal thread in hole; Described locking and pressurizing screw comprise screw rod withHead, is useful on the screw thread of inserting that screws in knochenbruch on described screw rod, described locking and pressurizing screw head is establishedBe equipped with the locking screw thread coordinating with locking and pressurizing hole.
Improve as one, described internal malleolus fixation steel plate bending section end is provided with and hooks shape projection. CanCatch on internal malleolus nose part, strengthen fracture fixation.
Further improve as above-mentioned improvement one, described hook shape projection is that left and right is arranged side by sideTwo. Make stress equalization, strengthen stationarity.
Preferred as one, described internal malleolus fixation steel plate bending section is horizontally arranged with 2 locking and pressurizing holes,Described internal malleolus fixation steel plate flat segments is provided with 4 locking and pressurizing holes along its bearing of trend. Locking and pressurizingScrew and the cooperation of internal malleolus fixation steel plate have locking action, have and can pressurize in implantable bone. Many pressurizationsLock screw coordinates, and knochenbruch is carried out to locking compress, realizes complicated fracture of medial malleolus anatomical reduction and reinforcementFixing.
Improve as one, on described internal malleolus fixation steel plate bending section, have the Ke Shi passing for Kirschner wirePin hole. Can need to squeeze into Kirschner wire according to the reduction of the fracture.
Usefulness of the present utility model is: there is the internal malleolus steel plate fixed system of said structure, inLocking and pressurizing screw can be squeezed in locking and pressurizing hole on ankle steel plate, and this screw not only has pulling force effect,Himself can also be locked on steel plate, form the Trinitarian stable fixing of nail, plate and surface of bone.
