Description
Technical field
The invention belongs to a kind of medical apparatus and instruments, relate in particular to fracture fixation apparatus.
Background technology
Accompany the fracture of tibia of serious soft tissue injury is stubborn problem, especially a distal tibial fracture in treatment, has in the world multiple therapy methods.At present, treatment by stages is approved by most of orthopedists in the world gradually.Treatment by stages comprises: the treatment of first phase exterior fixation bracket, and it can help soft tissue recovery or the row flap of damage to perform the operation to cover the osseous tissue exposing; Second phase is row steel plate internal fixation treatment again.But treatment by stages needs second operation, it is many that patient bears misery, somewhat expensive.Therefore, there is scholar to propose directly to adopt exterior fixation bracket first stage for the treatment of to accompany the fracture of tibia of serious soft tissue injury; It only need to once be performed the operation, and expense can reduce by half; But traditional exterior fixation bracket is bulky, when lower limb use, usually affects normal activity, and affect attractive in appearance.For fracture around joint, traditional exterior fixation bracket often needs trans-articular to fix in addition, and the time has been grown the later joint motion that affects, and causes ankylosis.
Summary of the invention
Technical problem to be solved: provide a kind of distal tibial external fixer for above problem this utility model
,volume is little, and low incisura does not affect joint motion, does not need second operation, reduces patient painful, the external fixer that cost is low.
Technical scheme: in order to overcome the above problems, the invention provides a kind of special lower limb external fixer, T-shape, is comprised of crosspiece and perpendicular section, it is characterized in that, crosspiece is circular arc, be connected with perpendicular section, perpendicular section is divided into vertical the first canned paragraph, vertical the second canned paragraph, vertical the first canned paragraph and vertical the second canned paragraph are 90-120 degree arc, in crosspiece and perpendicular section, have screw hole.
Described a kind of distal tibial external fixer, is characterized in that, crosspiece, and vertical the first canned paragraph, vertical the second canned paragraph is symmetrical about the vertical central axis of crosspiece.
Described a kind of distal tibial external fixer, is characterized in that, vertical the first canned paragraph span access location length that is connected with vertical the second canned paragraph is less than vertical the first canned paragraph or vertical the second canned paragraph length.
Described a kind of distal tibial external fixer, has Kirschner wire locating hole in crosspiece and perpendicular section.
Described a kind of distal tibial external fixer mainboard crosspiece width is 10 millimeters to 20 millimeters, and vertical the first canned paragraph and vertical the second canned paragraph are wide 20 millimeters to 30 millimeters respectively.
Described a kind of distal tibial external fixer, a kind of distal tibial external fixer thickness is 3 millimeters to 5 millimeters.
Described a kind of distal tibial external fixer, 3.5 millimeters of crosspiece screw hole diameters, 4.5 millimeters of perpendicular section screw hole diameters.
Described a kind of distal tibial external fixer, screw hole is universal lock screw hole.
Described a kind of distal tibial external fixer, the perpendicular section surface of crosspiece is smooth.
Described a kind of distal tibial external fixer, a kind of distal tibial external fixer is made by titanium alloy.
Bone fracture internal fixing device, as built-in steel plate and intramedullary pin, is positioned in bone surface or pulp cavity, and skin soft tissue below links together sclerite in conjunction with screw, after waiting union of fracture, need to be in hospital, and after anesthesia in operating room, fixing removal surgery in row.External fixer links together sclerite by screw equally, but external fixer main part is positioned over skin soft tissue surface, only has screw to be fixed on skeleton by skin soft tissue; Therefore, after waiting union of fracture, directly under outpatient service local anaesthesia or need not anaesthetize the screw of back-outing, i.e. dismountable external fixer.
Beneficial effect: this utility model provides a kind of distal tibial external fixer, crosspiece is with perpendicular section special shape and distal tibial shank of living in and three-dimensional fixed effect is applied ointment or plaster, had to ankle position profile, intensity is large, can realize not trans-articular fixes, because its occupation mode is outer fixing, therefore can use to union of fracture always, do not need second operation, reduce sufferer painful, save medical resources.Volume is little, can be hidden in clothes, does not affect patient's daily routines, does not affect the appearance, and easily by patient, is accepted.
1 crosspiece, vertical the first canned paragraph, vertical the second canned paragraph, about vertical centrage symmetry, make a kind of distal tibial external fixer be symmetrical structure, can be applicable to left lower limb and right lower limb simultaneously.
Between 2 vertical the first canned paragraphs and vertical the second canned paragraph, form hollow structure, convenient nursing.
3 locating holes are for temporary fixed, are convenient to adjust in art external fixer position.
The more common built-in plate of 4 perpendicular section is wide, and be divided into vertical the first canned paragraph and vertical the second canned paragraph, contribute to form three-dimensional fixed effect, meet skeleton fixing needs outward, vertical the first canned paragraph and vertical the second canned paragraph are wide 20 millimeters to 30 millimeters respectively, screw hole has sufficient space, and more common built-in plate is wide, and constant intensity is large.
5 more common built-in thicknesss of slab of external fixer, not yielding, constant intensity is better.
6 distal tibials are spongy bone, sclerite is often smaller simultaneously, tradition external fixer locking pin is thicker, on the less sclerite of distal tibial, be difficult for fixation, often need trans-articular to fix, this external fixer crosspiece has abundant screw hole, and 3.5 millimeters of screw hole diameters, for the less sclerite of distal tibial, can also adopt many pieces of screws to be fixed, thereby realize not trans-articular, fix; Tibial shaft is cortical bone, and 4.5 millimeters of vertical section screw hole diameters are comparatively applicable.
The use of 7 universal lock screw holes, can allow doctor select suitable angle bone fixation folded block.
8 crosspieces and perpendicular section surface are smooth, are not easy to occur scratching, can avoid sufferer in the process of wearing the clothes to the affecting of fixture, convenient nursing.
9 titanium alloy materials are made a kind of good biocompatibility of distal tibial external fixer, non-corrosive, easily sterilization.
