Abstract

The invention relates to a medical minimally-invasive broken screw taking-out device which comprises a first handle and a second handle. The middle portion of the first handle and the middle portion of the second handle are movably connected through a rotating shaft. A locking device is movably arranged between the same ends of the first handle and the second handle. A plurality of anti-sliding tooth grooves are formed in the inner sides of the other ends of the first handle and the second handle. According to the medical minimally-invasive broken screw taking-out device, a screw in a bone can be screwed out conveniently, so that sclerotin damage around the screw is lowered to the minimum degree. Meanwhile, the medical minimally-invasive broken screw taking-out device has a locking function, the locking device can be detached, and practicability is high.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a medical minimally invasive device for removing broken nails. Background technique [0002] After internal fixation of extremity fractures with plates and screws, due to the high stress between the plates and screws, long-term retention in the body often leads to breakage at the contact between the tail of the screws and the plates. It is difficult to remove the broken screw. At present, it is usually necessary to remove a large amount of bone around the broken screw in clinical practice, and use tools such as rongeurs to remove the screw. This method is more serious to bone destruction, and local refracture may occur after operation. At present, there is no medical minimally invasive broken nail removal tool that can conveniently take out the broken nail and can destroy the bone at least. Contents of the invention [0003] The invention provides a medical minimall...
