Orthopedic implant instrument

Abstract

The invention provides an instrument for an orthopedic implant. The instrument is used for solving the problem that an existing orthopedic drilling tool is prone to causing soft tissue injury. Comprising a sleeve; the transmission rod is provided with a transmission piece located at one end of a rod body, the transmission piece is located in the sleeve and provided with a first containing groove, and a plurality of first meshing teeth are arranged around the first containing groove; the drilling rod is provided with a plurality of second meshing teeth which are arranged around a second containing groove, a combination part is located between the second containing groove and a blade part, the combination part is combined with the sleeve, and the blade part is located outside the sleeve; and the two magnets are respectively arranged in the first accommodating groove and the second accommodating groove, and the same poles of the two magnets are opposite to each other.

Description

technical field [0001] The invention relates to an instrument for surgery, in particular to an instrument for orthopedic implants used for drilling in orthopedic surgery. Background technique [0002] At present, when a bone injury occurs, if the effective treatment is not given in time, the blood circulation supplying the bone will be damaged or blocked, resulting in bone cell necrosis and bone collapse and other problems. Common bone injury treatment operations include implantation of bone implants such as bone nails or bone plates, and drilling operations in the bone are unavoidable during the operation. [0003] The current drilling method is to remove the bone tissue at the place where the hole is to be drilled by the operator holding an electric drill with a high-speed rotating drill bit. During the drilling process, the operator needs to continue to apply force in the direction of the drilling, especially when drilling on the cortical bone with high hardness; in othe...

AI Technical Summary

Problems solved by technology

During the drilling process, the operator needs to continue to apply force in the direction of the drilling, especially when drilling on the cortical bone with high hardness; in other words, before the drill drills through the bone, The operator will be very hard, so if it is too late to pull the drill back or stop the drill immediately at the moment of drilling through the bone, the tip of the drill will cause damage to the soft tissue adjacent to the bone. Drilling operations need to rely on the experience and feel of the operator, so as not to cause sequelae of soft tissue damage due to excessive drilling force and excessive drilling force, which will lead to medical disputes
