Medical hybrid electrical device and driving method thereof

Abstract

The invention relates to the field of electrical surgical tools and is required to solve the technical problem of overcoming the defects of the prior art to design a medical hybrid electrical device that is capable of choosing torque according to actual needs and a driving method thereof. The device comprises a main control panel providing control, a hand machine head used for surgical operation and a knife used for implementation operation, wherein the main control panel provides power for the hand machine head by a driving mechanism to drive the knife at the front end of the hand machine head, the driving mechanism comprises two driving structures with different torques which are applicable to destructive surgery and fine surgery respectively. The invention is provided with two kinds oftorque for freely choosing and has the advantage that the driving structure with small torque is applicable to fine surgery such as bone supplying area cutting and the like so as to ensure cutting precision; and the driving structure with large torque is applicable to rough destructive surgery, thus accelerating the surgery.

Description

technical field [0001] The invention relates to the field of electric surgical tools, in particular to a medical dual-power electric instrument device and a driving method thereof. Background technique [0002] In the existing bone surgery in the world, the main engine of electric equipment is all driven by a single power. Its disadvantage is that it has a single power and a single torque, and its application range is limited. In actual medical work, some operations can only use equipment with small power and low torque, such as bone surgery of facial features and hand surgery and partial maxillofacial bone plastic surgery. It is not suitable to use equipment with high power and high torque for these operations, because the surgical field of view is small, and the knives Difficult to place. However, some destructive cranio-maxillofacial surgeries have a large field of view and low precision requirements, and the surgery can be completed quickly with high-power and high-tor...

[0004] Single power and single torque hinder the development of hospital technology

It is not enough for some hospitals to only have single-power equipment. Whether it has high-power or small-power equipment, its business development is restricted, such as: some operations are destructive operations and at the same time need to be reconstructed immediately after destruction, destruction and reconstruction The operation can be carried out at the same time. After the destruction operation is completed, the operation on the donor area will be performed next, which prolongs the operation time and increases the pain of the patient.
