Long-pole telescopic screw fastening device for orthopedic interventional operation

Abstract

The invention discloses a long-pole telescopic screw fastening device for an orthopedic interventional operation. The long-pole telescopic screw fastening device comprises a handle, wherein the handleis of a hollow structure; a rechargeable battery is arranged inside the handle; a first button and a second button are arranged on the sides of the handle; a sleeve is arranged at one end of the handle; a first protective shell is arranged on the side of the sleeve; a first motor is arranged inside the first protective shell; a gear is arranged on the output shaft of the first motor; a second protective shell is arranged at one end of the sleeve; a second motor is arranged inside the second protective shell; the output shaft of the second motor is inserted into the sleeve and connected with alead screw; a thread bushing is connected to the lead screw in a sleeving manner by virtue of a thread; a slide bar is fixed on the side of the thread bushing; a chute is formed in the inner wall ofthe sleeve; one end, which is far away from the thread bushing, of the slide bar is arranged in the chute in a sliding manner. The long-pole telescopic screw fastening device disclosed by the invention is capable of realizing intelligent operations, simple in operation and very high in efficiency.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a long rod sleeve screw fastening device for orthopedic interventional operations. Background technique [0002] Minimally invasive interventional surgery in orthopedics is a new surgical technique that achieves surgical efficacy with minimal invasion and physiological disturbance. It not only has a small incision, but more importantly, it has better internal environment stability, lighter systemic reactions, shorter healing time, less scar healing, and better psychological effects. [0003] In minimally invasive orthopedic surgery, it is often necessary to perform bone connection surgery at small incisions. In traditional surgery, large incisions are often made with steel plates and screws to fix and reset the cracked bone surface. The screw installation is generally done manually. This is very inconvenient to operate, and the efficiency is relatively low. Content...
