Embodiment 1

[0040] Such as Figure 1-4 As shown, a device for removing broken orthopedic hollow nails includes a device body 1, on which a main rod 2 is arranged, and the same side of the main rod 2 is respectively fixedly installed with first installation sides from top to bottom. The rod 5 and the second installation side rod 12, the first installation side rod 5 is movably connected with a connecting rod 6, the bottom of the connecting rod 6 is welded with a chuck 14, and the second installation side rod 12 is detachably connected There is a punching nail 13, the top surface of the punching nail 13 is provided with a slot 17, the chuck head 14 is matched with the slot 17, and the lower end of the main rod 2 is provided with a nail-taking installation part 8.

Embodiment 2

[0042] On the basis of Embodiment 1, the nail-removing installation part 8 has a T-shaped slot 9 with an open lower end, and the cap of the nail-removing nail 10 is matched and engaged with the T-shaped slot 9 .

Embodiment 3

[0044] On the basis of Embodiments 1 and 2, further, the depth of the longitudinal opening of the T-shaped slot is greater than the depth of the transverse opening.

Abstract

The invention discloses a broken hollow nail take-out device for the orthopedic department. The broken hollow nail take-out device comprises a device body, the device body is provided with a main rod,a first mounting side rod and a second mounting side rod are fixedly installed at the same side of the main rod from top to bottom respectively, a connection rod is movably connected to the first mounting side rod, a clamping head is welded to the bottom of the connection rod, a punching nail is detachably connected to the second mounting side rod, a clamping groove is formed in the surface of the top of the punching nail, the clamping head is matched with the clamping groove, and a nail take-out nail mounting part is arranged at the lower end of the main rod. Through the working mode of mutual cooperation of dual nails, the problems in the prior art that a nail breaking fracture face is unsmooth, and cannot be fixed and rotated are solved; the punching nail is provided with a conical nail head, the nail head is provided with a thread used for removing un-smoothness of the fracture face, the head of a nail take-out nail achieves maximal threaded combination for the plane, the cooperation of the main rod and the side rods makes the main rod and the side rods more convenient to control and use, the structures are optimized, and the operating difficulty is lowered.

Description

Technical field: [0001] The invention relates to the technical field of medical aids, in particular to a device for removing broken orthopedic hollow 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 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 situa...
