Abstract

The invention relates to the field of medical instruments, in particular to an installation device for transverse external fixation needles for the hand bones. The installation device for the transverse external fixation needles for the hand bones comprises two second rotary connectors, two second connecting rods, two third rotary connectors and the two second fixation needles; the two second connecting rods are arranged on fixing rods through the second rotary connectors respectively, and the second fixation needles are fixedly connected with the second connecting rods through the third rotary connectors; by adjusting the positions of the two second rotary connectors, the two second connecting rods and the two third rotary connectors, the two second fixation needles are opposite to each other. The device provides a structure of the transverse external fixation needles, the structure is simple, fixation and adjustment are convenient, the hand bones can be stably and effectively fixed at multiple angles, and the surgery is conveniently carried out.

Description

Technical field [0001] The present invention relates to the field of medical equipment, and in particular to an installation device for a hand bone lateral external fixation needle. Background technique [0002] The Chinese invention patent (CN105411659A) discloses an orthopedic external fixation frame, which includes a support rod, a nail rod clamping mechanism and a bone nail. The nail rod clamping mechanism is provided with an array. Each group is mainly composed of a U-shaped clamp I, a ball handle, Bolt composition. One end of the ball shank is provided with a ball head, a neck is provided in the middle, and the other end is provided with a tapered threaded hole. The tapered threaded hole is used to install the bone nail. In the ball socket, the ball head is provided with an inner hole. The inner hole is composed of two tapered holes. The small openings of the two tapered holes are connected to the large opening outwards. The U-shaped clip I is elastic, and its bottom is se...
