Abstract

The invention discloses an external fixator for orthopaedics, relates to the technical field of the medical apparatus and instruments of the orthopaedics, and solves the problems that the external fixator for the orthopaedics can not firmly fix bones, is liable in wound infection and is uncomfortable in wearing. The external fixator for the orthopaedics comprises a fixing sleeve, wherein two endsof the fixing sleeve are independently provided with a fixing mechanism; the outer surface of the fixing sleeve is provided with movement grooves; a movement rod is installed in each movement groove;one side of each movement groove is provided with a chute; clapboards are arranged on the top of each chute; one side of each clapboard is provided with a spacing hole; the outer side of the fixing sleeve is provided with connecting rods; two ends of each connecting rod are independently provided with a supporting rod; one end of each supporting rod is provided with a fixing ring; each supportingrod and each fixing ring are connected through a hold-down nut; and pin holes are arranged in each supporting rod. The external fixator is convenient in regulation, bone fixing stability is improved,the wearing comfort of a patient is improved, and the wound infection of the patient is reduced.

Description

technical field [0001] The invention relates to the technical field of orthopedic instruments, in particular to an orthopedic external fixator. Background technique [0002] At present, when clinical orthopedic surgeons select external fixators for long tubular bone fractures, the orthopedic external fixator is the most commonly used, which has the characteristics of safety and firmness. It consists of a main frame, a side compression rod, a fixed pin, and a "T"-shaped sleeve. The main frame is divided into three parts, and the three parts are connected by universal joints. Mount the segment for the pin. The telescopic adjustment section is a sleeve structure, and a fastening screw is designed on the sleeve to fix the length of the telescopic adjustment section. After the fixation pin is driven into the bone, it is fixed by the fixation pin installation section. [0003] However, the existing orthopedic external fixator does not have enough clamping force on the bone, and...
