Abstract
The utility model relates to an outer restoring fixing device for the fracture of bones in the shape of long tubes, belonging to a medical appliance. The utility model is composed of a needle holding device and a connecting rod assembly, wherein, one end of the needle holding device is fixed with an adjusting arm into a whole, and a pressurizing device is arranged on the connecting rod assembly. The pressurizing device is arranged in a pressurizing adjusting sleeve by a pressurizing screw rod, and the other end of the pressurizing adjusting sleeve is provided with a pressurizing pedestal fixed by a conicity pin. An adjusting hand wheel is arranged on the pressurizing screw rod, and the other end of the pressurizing screw rod is provided with a pressurizing seat which is limited by a spacing pin. Needle locking devices with screw rods are respectively additionally arranged on the adjusting arm and a guide rod. The utility model has the advantages of reasonable structure, easy manufacture, convenient operation, high mechanical property and high fixing performance. The recovery and the fixation are carried out simultaneously, and the utility model is suitable for the outer fixation of the fracture of bones in the shape of long tubes.
Description
This utility model belongs to medical apparatus and instruments, refers in particular to external immobilizer for fracture restitution.
The existing miscellaneous fracture external fixator that resets, kind is more, the single arm type external immobilizer for fracture restitution, it is by holding needle device and link assembly constitutes, and it is relatively simple for structure, and axial force is relatively poor.Bilateral formula external immobilizer for fracture restitution, Kirschner wire passes tissue, and is big to skin injury.And semi-ring formula external fixator, to the health fixation, good stability, but volume is bigger, and heaviness is unfavorable for that patient has a rest.
The existing patent No. is 952307812, patent name is the patent of " combination single arm type external immobilizer for fracture restitution ", be by holding needle device and link assembly constitutes, be to integrate flexible, translation, rotation, displacement to become the multi-functional holder in angle with direction, its good mechanical property, fixed performance is good, and volume is little, in light weight, make to reset and fix synchronously.Its shortcoming is the link assembly complexity, adjusts guide post and adjusts the arm installation length by adjusting cover, ring washer semicircle cover, alignment pin and lock nut, and is to adapt to the length of synthetism, not convenient during operation.
The purpose of this utility model provides a kind of on-load carries out machinery to fracture and adjusts, and helps patient and has a rest and early ambulant, and operation is convenient, reaches to reset and the fixing synchronous long tubular bone fracture external fixator that resets.
The purpose of this utility model is achieved in that by holding needle device and link assembly constitutes.One supports needle device is fixed as one with adjusting arm, and another supports needle device and is connected with link assembly with the tapering pin through universal joint.Hold needle device and can adopt the lateral arrangement structure.Link assembly is equipped with the guide post that an end has stop screw for adjusting in the arm, locate by holding screw, on adjustment arm and guide post, pressue device is housed, the pressue device structure is adjusted in the cover for the pressurization screw rod is contained in pressurization, pressurization is adjusted the cover other end and is the fixed pressurization base of pressurization tapering pin, on the pressurization screw rod adjustment handwheel is arranged, the other end is pressure foot, and is spacing by spacer pin.Eccentric fixed axis and spheroid seat are housed on the guide post, universal joint are connected with the spheroid seat by the spheroid gland.
For realizing the purpose of this utility model, link assembly adopts three kinds of forms.
Adjustment arm in first kind of link assembly is a structure of having only the pressurization base aperture.
Adjustment arm in second kind of link assembly is first kind and adjusts on the arm and add loading screw purl device.Screw rod purl device constitutes by holding pin screw rod, packing ring and nut.
The guide post other end in the third link assembly directly is equipped with screw rod purl device.
This external fixator learns in conjunction with the row booster, the mechanics of materials and human anatomy, and biomechanics and clinical manifestation and therapy design for the basis in Principle of Mechanical Designing and the wound.
The utility model has the advantages that, integrate flexible, translation, rotation, displacement and become the angle multi-functional with direction.Good mechanical property is accurate, firm, stable.Fixed performance is good, and the plane of threading a needle can be selected, and is beneficial to working doctor.Volume is little, and is in light weight, but patient's early ambulant promotes healing.Adopt pressue device to adjust synthetism length, be convenient to operation.Be suitable for general fracture and several sections of fracture external fixation, make to reset and fix synchronously and carry out.
Below in conjunction with drawings and Examples this utility model is elaborated.
