Abstract

The invention relates to the field of medical instruments, in particular to a force application device, and a nail puller with a hammering reset function. The force application device comprises a mounting rod, a force storage cylinder arranged on the mounting rod in a sliding and sleeving mode and a force application piece arranged in the force storage cylinder, wherein one end of the mounting rod is connected with the nail puller, and the other end of the mounting rod is fixedly connected with an abutting piece; the force application piece comprises a hammering sleeve and a force storage spring which are sequentially arranged on the mounting rod in a sleeving mode, one end of the force storage spring abuts against the hammering sleeve, the other end of the force storage spring abuts against the end, away from the abutting part, of the force storage cylinder, and under the elastic force effect of the force storage spring, the hammering sleeve abuts against the abutting part; and when the pressure is applied to the force storage spring, the force storage spring pushes the hammering sleeve to hammer the abutting piece when the pressure is released by the force storage spring. The nail puller has the effects that a nail pulling process is more labor-saving, and convenience in nail pulling is greatly improved.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to a force applicator and a nail puller with a hammer reset function. Background technique [0002] The nail puller can be widely used in various industries such as medical treatment, power supply, furniture, decoration, office, packaging, etc., and is a popular tool that can be widely used. During use, the nail is clamped by the nail puller, and then an outward pulling force is manually applied to the nail puller to pull out the nail. [0003] However, when manually applying an outward pulling force to the nail puller, it is necessary to apply a continuous and large pulling force to the nail puller; or it is necessary to tap the nail puller in a direction away from the nail with the help of an external hammer or other items. It is very laborious to pull out the nail, and the operation is very troublesome. [0004] Especially in the medical field, such as intramedullary na...
