A surgical nail removal device for orthopedic medical treatment

Abstract

The invention discloses a surgical nail taking device for orthopedic treatment. The surgical nail taking device comprises a support plate, wherein clamping plates are mounted on two sides of the lower end of the support plate; an annular rotational groove is formed in the middle of the upper end of the support plate; a rotating base is mounted at the upper end of the annular rotational groove; a fixing device is connected between two sides of the lower end of the rotating base and the support plate; a buffer pad is mounted in the middle of the upper end of the rotating base; a holding pad is mounted in the middle of the upper end of the buffer pad; a constraint rack is mounted at the upper end of the holding pad; support racks are mounted on two sides of the upper end of the rotating base; top plates are mounted at the upper ends of the support racks; a first screw rod is mounted between upper ends of the support racks; a first sliding block is mounted in the middle of two ends of the first screw rod; a lifting pull rod is mounted at the lower end of the first sliding block; a lifting pull plate is mounted at the lower end of the lifting pull rod; a nail taking tank is mounted at the lower end of the lifting pull plate. By adopting the surgical nail taking device, bone nails can be clamped and taken out, convenience is brought to medical operators to take out bone nails of orthopedic patients, and meanwhile due to adoption of a completely mechanical structure, defects of a hydraulic system are avoided.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a surgical nail removal device for orthopedic medical treatment. Background technique [0002] Fracture refers to the complete or partial break of the continuity of the bone structure. Due to the relatively loose bone quality, the elderly are prone to fracture without external force, that is, in the case of daily activities. For teenagers or adults, Generally, fractures do not occur normally. Only when the bones are subjected to great external force, such as: impact, falling from a high place, car accident, etc., will cause great damage to the bones, resulting in fractures. In fractures, Joint fractures and tibial plateau fractures are the most common. With the development of medical technology, CT diagnosis is more and more widely used, and the diagnostic rate of tibial plateau fractures in fractures is also increasing with the development of these technologies. . ...

AI Technical Summary

Problems solved by technology

[0003] After the diagnosis, the bone fragments at the fracture site are usually rejoined by steel plates and bone nails, so that the broken bone fragments are reconnected tightly under the action of the bone nails, and after a long period of postoperative growth, fracture New calluses will grow out of the bone fragments and grow back together. After the bones grow together, the bone nails that were previously driven into the bones must be removed. In the process of manually removing the nails, often due to too much force Small, making it difficult to remove the staple or increasing the pain of the patient

And manual nail removal is very time-consuming and labor-intensive, and the stability is low

[0004] Chinese patent (notification number: CN206303967U) discloses a surgical nail remover for orthopedic medical treatment, including a base, a chassis and a control box, although this device increases the efficiency of medical staff in removing bones from orthopedic patients to a certain extent, However, this device uses a hydraulic device to fix and pull out the bone nail, and it is difficult to control its strength during use. At the same time, the hydraulic device is also very heavy and prone to hydraulic oil leakage, which is poor in practicability
