A device for removing broken orthopedic nails

Abstract

The invention discloses a broken nail removal device for the orthopedics department. The broken nail removal device comprises a device body, the device body is provided with a main rod, one side of the main rod is detachably connected with a horizontal rod, a first mounting side rod is fixedly mounted at the other side of the main rod and movably connected with a connecting rod, a clamping head iswelded to the bottom of the connecting rod, a limit bolt is mounted at the side end of the first mounting side rod, the connecting rod is fixedly connected with the first mounting side rod through the limit bolt, and the bottom of the main rod is fixedly connected with a retractable main rod; the broken nail removal device is provided with a punching mechanism and a nail removal head, a threadeddrill bit is arranged on the punching mechanism, and a threaded hole can be drilled in a broken nail through the threaded drill bit and then is in threaded connection with the threaded drill bit through the nail removal head so that the broken nail can be removed by rotating the horizontal rod. The broken nail removal device is reasonable in structure and convenient to operate, compared with traditional modes of etching outer threads on broken nails, damage to bones is smaller, and the pain of patients is relieved.

Description

Technical field: [0001] The invention relates to the technical field of medical aids, in particular to a device for removing broken orthopedic nails. Background technique: [0002] In orthopedic surgery, internal fixation with screws combined with steel plates and hollow nails is a commonly used method, because hollow nails have structural advantages that ordinary screws do not have, so hollow nails are used very frequently. However, although the process of taking out the hollow nail is relatively simple, it often happens that the hollow nail cannot be rotated, and some bone nails are tightly combined with the bone, causing the bone nail to be broken and damaged, so that the forceps extractor has to be used. The bone is more destructive, causing unnecessary pain to the patient. [0003] In the prior art, in the process of taking out the broken nail, the broken nail often cannot be fixed, the broken nail slips, the cross section is uneven, and it cannot be rotated. This situ...

Problems solved by technology

However, although the removal process of the hollow nail is relatively simple, it often happens that the hollow nail cannot be rotated, and some bone nails are tightly combined with the bone, causing the bone nail to break and damage, so that the forceps extractor has to be used. The bone is more destructive, causing unnecessary pain to the patient

[0003] In the prior art, in the process of taking out the broken nail, the broken nail often cannot be fixed, the broken nail slips, the cross section is uneven, and it cannot be rotated. This situation leads to some patients who cannot take out the broken nail after the fracture has healed, or use a relatively destructive method to remove the broken nail. or traumatic removal

[0004] The broken nail removal device is a commonly used medical device in orthopedics. The existing broken nail removal device usually engraves external threads on the surface of the broken nail when used, and the tapper needs to be moved along the outer ring of the broken nail during the calibration process. Rotation, greater bone damage, increased patient pain
