Abstract
The invention discloses an improved thread clamping structure of a bone tunnel threading device. The improved thread clamping structure comprises a threading tube elbow and a steel wire ring, wherein thread clamping components which separate steel wires at the two ends of the steel wire ring to facilitate thread clamping of the steel wire ring are arranged inside and outside the end of the threading tube elbow. According to the improved thread clamping structure, one tube does not need to be pressed into two tubes to make a thread clamping structure at the end of the elbow, and the thread clamping structure is composed of the thread clamping components instead; the tubes at the end of the elbow do not need to be pressed through a mold, so that the tubes can be made thin and small, and the thinner drilling is, the smaller damage to bones is, and the smaller possibility of mistaken damage to muscular tissue beside the bones is; meanwhile, tube walls can be made thick and hard, so that an instrument is hard and not prone to deformation on the condition that thin tubes are used, and the service life is greatly prolonged; compared with mold pressing, the improved thread clamping structure is easy to process.
Description
Technical field
The present invention relates to a kind of osseous tunnel threading apparatus clamping-line structure of improvement.
Background technology
As shown in Figure 1, a kind of osseous tunnel threading apparatus, promotes push rod push rod 1 left, push rod 2 indentation left can be driven, when the elbow 3 of threading apparatus inserts bone network, release push rod push rod 1, under the action of the spring, push rod 2 advances to the right, make push rod 2 contact bone network, now, can with thimble through push rod 2 and bone network, lines are sent into wire loop 5, i.e. threading; Left and right promotes steel wire push rod 4, and can drive wire loop 5 indentation of elbow 3 end face or stretch out, wire loop 5 stretches out, and is convenient to threading, wire loop 5 indentation, is convenient to clamping lines and exits from bone network.As shown in Figure 2, a kind of osseous tunnel threading apparatus, the clamping-line structure of its penetration pipe elbow ends is: by the end 31 of elbow 3, is pressed into two pipes, like this by a pipe, the steel wire at wire loop 5 two ends is separated, be located at respectively in two pipes being pressed into, make wire loop 5 be conducive to threading, simultaneously, wire loop 5 indentation, is conducive to clamping lines.The metal tube of this structure to penetration pipe elbow ends 31 has requirement: the first, and pipe is relatively thicker, otherwise is easy to shrivel; The second, die sinking, cost is high; 3rd, easily damage; 4th, tube wall will thinlyyer could be shaped, and therefore, finished product is easily out of shape when fastening bone, and threading is forbidden; 5th, because wall is thin, be easily out of shape after apparatus is repeatedly applied.Visible, the structure that this mould presses out: pipe is thick, and wall is thin, and matter is soft, difficult processing, yielding.
