Problems solved by technology

[0002] At present, the screw removal tools commonly used in orthopedics are difficult to operate. It is time-consuming and labor-intensive to disassemble and assemble tightly installed screws. Sometimes, too much force may cause bone cracks or bone fragments, and insufficient force may cause screws to loosen. Such problems not only cause great suffering to patients, but also cause great trouble to the work of medical staff.

Embodiment Construction

[0019] Such as figure 1 As shown, a trauma-reducing orthopedic dismounting screw device includes a knife head fixing buckle 1, a length of 30 cm and a diameter of 1 cm for a force rotating rod. It is connected with the rotating handle 3, and the non-connecting end of the rotating handle 3 is connected with the booster rotating seat 4 through a straight rod. When in use, the knife head is fixed with the buckle 1 and connected with the screw. The doctor holds the booster rotating seat with one hand and the other hand Rotate handle 3, and make, can screw in or screw out steel plate.

[0020] preferred, such as Figure 4 Among them, a universal rotating wheel 7 is provided in the said booster rotating seat 4, when the screw needs to be taken out with a greater force, the universal rotating wheel 7 of the rotating seat 4 can be close to the doctor's shoulder, and the The fixing buckle 1 of the cutter head is in contact with the screw on the steel plate, and then the rotating hand...

Abstract

An orthopaedic dismounting screw device for reducing trauma comprises a knife head fixing clasp, one end of a force-applying rotary lever is connected with the knife head fixing clasp, the other end is connected with a rotary handle, and a non-connecting end of the rotary handle is connected with a force-applying rotary seat through a straight lever. The novel patent of the invention has the following characteristics: simple structure, convenient use, safety and reliability, low cost, simple, convenient, time-saving, labor-saving and convenient for medical personnel to use, and solves the fixing and dismantling operation of the fixing screw which is difficult to be dismantled in orthopaedics.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to an orthopedic disassembly and assembly screw device for reducing trauma. Background technique [0002] At present, the screw removal tools commonly used in orthopedics are difficult to operate. It is time-consuming and labor-intensive to disassemble and assemble tightly installed screws. Sometimes, too much force may cause bone cracks or bone fragments, and insufficient force may cause screws to loosen. Such problems not only cause great suffering to patients, but also cause great trouble to the work of medical personnel. Contents of the invention [0003] The new purpose of the present invention is to provide a trauma-reducing orthopedic screw removal device, which can not only overcome the existing screw disassembly defects, facilitate the screw disassembly process, but also give force setting to the difficult to disassemble screws , through precise application of force, so as...
