An orthopedic nail remover for easy removal of broken nails

Abstract

The invention discloses an orthopedic nail remover which is convenient for removing broken nails, and belongs to the technical field of nail removers. The outer periphery of the drilling mechanism of the orthopedic nail remover is provided with a guide mechanism, and the second guide part of the guide mechanism is provided with a traction mechanism for applying an upward traction force to the broken nail; the first guide part is fixedly connected with the support device, and the second The guide part is rotatably arranged on the lower part of the first guide part, and a plurality of metal detection sensors are arranged on the bottom of the first guide part, and a plurality of metal detection sensors are arranged at equal intervals at the junction of the second guide part and the first guide part. On the periphery, a plurality of metal detection sensors and a drilling mechanism are electrically connected to the controller. The orthopedic nail remover of the present invention realizes precise drilling and real-time monitoring during the drilling process, avoids the deviation between the drill bit and the broken nail, realizes drilling through the traction device and avoids chiseling of the surrounding bone; the invention can safely The broken nail can be effectively removed without causing great loss to the bone, and the difficulty of removing the nail can be reduced.

Description

technical field [0001] The invention relates to the technical field of nail-removing instruments, in particular to an orthopedic nail-removing device for removing broken nails. Background technique [0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system. Fractures are one of the most common conditions in orthopedics. [0003] In the trauma treatment of fracture patients, bone plate and screw fixation are often used clinically. During the recovery period of patients, it is common for screws to break due to various reasons. Whether it is removal of internal fixation or internal fixation replacement, For orthopedic surgeons, it involves the thorny issue of taking out the broken nail; one of the current methods for taking out the broken nail is to first chise...

[0003] In the trauma treatment of fracture patients, bone plate and screw fixation are often used clinically. During the recovery period of patients, it is common for screws to break due to various reasons. Whether it is removal of internal fixation or internal fixation replacement, For orthopedic surgeons, it involves the thorny issue of taking out the broken nail; one of the current methods for taking out the broken nail is to first chisel out the bone around the broken nail, and then use tools such as pliers to hold and rotate the broken nail and then remove the broken nail. Take it out. If the distance between the top of the broken nail and the top of the bone canal is large, more bone needs to be chiseled out, which will cause greater damage to the bone. The second method is to drill a threaded hole on the top of the broken nail, and then By inserting the threaded part into the threaded hole and rotating it, the broken nail is driven to rotate and the broken nail is taken out. When drilling the threaded hole, the broken nail will not be reversed due to the downward pressure exerted by the drill bit on the broken nail. direction, so it is necessary to clamp the broken nail when drilling the threaded hole, and because the clamping part needs a certain clamping space, it is still necessary to chisel out the bone around the end of the broken nail, which will still damage the bone cause greater damage; in addition, when adopting method two to drill holes, the drill bit is prone to deviate from the broken nail and cause damage to the surrounding bone. The traditional nail removal method in the prior art is not only time-consuming and laborious, but also It will cause great damage to the backbone structure, so there is a need for a broken nail remover that can successfully remove the broken nail without causing further damage to the bone
