Abstract
The utility model relates to an orthopedic outer fixer for hallux valgus, comprising a clamping plate and steel needles, wherein the clamping plate is formed by laminated contact of the two heads of a self-locking piece A and a self-locking piece B which are hinged into an adjustable angle by fixed bolts and fixed nuts; the middle part of each self-locking piece is provided with a cross bar; the plate surfaces of the two sides of the cross bars are mutually parallel, but not in the same plane; the plate surfaces at the near ends of the hinged positions are provided with hinging round holes; the plate surfaces of the far ends of the hinged positions are staggered with the contact surface of the two self-locking pieces by a half of the plate thickness, so that the plate surfaces of the far ends of the hinged positions of the self-locking piece A and the self-locking piece B are positioned in the same plane; the plate surfaces of the far ends of the hinged positions are provided with oval bolt holes; each oval bolt hole is connected with two slidable bolts and two slidable nuts; and the steel needles are tightly fixed on the self-locking pieces by the slidable bolts and the slidable nuts. The orthopedic outer fixer is easy to adjust the fixed angle, is flexible in use and good in stability, does not damage the soft tissue when being used for treating the hallux valgus operation, is beneficial to blood circulation, reduces the infection, shortens the postoperative rehabilitation time and relieves the pain of a patient.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of medical orthopedic instruments.
Background technology
Intoe is a kind of common foot's disease.Along with the growth of patient age, the intoe degree of deformity increases the weight of gradually, and intoe also can produce a lot of severe complications.At present, hospital generally all adopts modus operandis such as big foot resected bone, the rectification of first second metatarsal bone, transfer of tendon is improved symptom, recovers foot's function.When adopting traditional operation treatment, need carry out the hyperosteogeny skiving and cut a bone, handle with the plintlet pressure pad then, or section bone stump after orthopedic makes it to fix, heal with husky cloth, plaster fixation.But the traditional operation treatment postoperative rehabilitation time is long, and the patient suffering can't bear, and exists the joint to be prone to the defective that adhesion, big toe are stiff, be unfavorable for union of fracture and wound healing.
The utility model content
The purpose of this utility model provides the orthopedic external fixator of a kind of intoe, solve intoe patient convalescent period agonizing, joint and be prone to the problem that adhesion, big toe are stiff, be difficult for healing.
For realizing above-mentioned purpose, this utility model adopts following technical scheme:
The orthopedic external fixator of a kind of intoe; Comprise clamping plate and draw point; Said clamping plate are stackedly from locking plate two to be contacted, and be hinged to the clamping plate of an angle adjustable with set bolt and nut from locking plate and B by A, and each all has a strut rail from the centre of locking plate, and the plate face of strut rail both sides is parallel to each other but not at grade; Wherein have hinged circular hole on the plate face of hinged near-end; The plate of hinged far-end makes A in the same plane from the hinged distal plate face of locking plate from locking plate and B towards two contact surfaces from the locking plate thickness of slab that interlaces half, has oval bolt hole on the plate face of said hinged far-end; Each oval bolt hole with two slidably screw bolt and nut be connected, draw point is fastened on locking plate by screw bolt and nut slidably.
Said A is the 8-12 millimeter from locking plate and B from the width of locking plate.
Said A is the 2-5 millimeter from locking plate and B from the thickness of locking plate.
Said draw point is tapered thread half pin, no screw thread half pin or full pin.
Compared with prior art the utlity model has following characteristics and beneficial effect:
The plate face of the hinged near-end of this utility model has circular bolt holes, and the plate face of hinged far-end has oval hole slot, and two are hinged through set bolt and nut from locking plate, are easy to adjust fixed angle during use, use flexibly, and good stability,
The plate of the hinged far-end of the orthopedic external fixator of this utility model intoe makes A in the same plane from the hinged distal plate face of locking plate from locking plate and B towards two contact surfaces from the locking plate thickness of slab that interlaces half, is positive and negative relative status, guarantees fixed effect.
This utility model passes through the fixedly orthopedic bone of intoe of external fixator; Soft tissue injury not; Help blood fortune and recover, reduce and infect, rehabilitation duration after the desmopyknosis; Overcome the shortcoming that traditional operation treatment makes that the patient is agonizing in convalescent period, the joint is prone to adhesion, big toe is stiff, is difficult for healing, alleviated the patient suffering.
External fixation when this utility model is suitable for other bone surgeries, and can with the supporting use of existing bone external fixator, can be widely used in the orthopedic medical operating of intoe.
Description of drawings
Below in conjunction with accompanying drawing this utility model is done further detailed explanation.
Fig. 1 is the structural representation of this utility model.
Fig. 2 is the structural representation of this utility model part.
Fig. 3 is this utility model user mode figure.
Reference numeral: 1-A from locking plate, 2-B from locking plate, 3-strut rail, 4-draw point, 5-slidably screw bolt and nut, 6-set bolt and nut, the hinged circular hole of 7-, the oval bolt hole of 8-, the orthopedic bone of 9-intoe.
The specific embodiment
Embodiment is referring to Fig. 1, shown in 2; The orthopedic external fixator of a kind of intoe comprises clamping plate and draw point 4, it is characterized in that: said clamping plate are from locking plate 1 and the stacked clamping plate that contact, also are hinged to an angle adjustable with set bolt and nut 6 from locking plate 2 two of B by A; Each all has a strut rail 3 from the centre of locking plate; The plate face of strut rail 3 both sides is parallel to each other but not at grade, wherein has hinged circular hole 7 on the plate face of hinged near-end, and the plate of hinged far-end is towards two contact surfaces from the locking plate thickness of slab that interlaces half; Make A in the same plane with B from the hinged distal plate face of locking plate 2 from locking plate 1; Have oval bolt hole 8 on the plate face of said hinged far-end, each oval bolt hole 8 with two slidably screw bolt and nut 5 be connected, draw point 4 is fastened on locking plate by screw bolt and nut 5 slidably.
Said A is 8-12 millimeters with B from the width of locking plate 2 from locking plate 1.
