Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] A computer (PC) is a modern intelligent electronic device that can automatically and quickly perform a large number of numerical calculations and various information processing according to a pre-stored program. The minimum configuration in the present invention is CPU 2GHz, memory 2GB, hard disk 180GB; operating system is windows 2000 / 2003 / XP. The inventor mainly uses the computing power of the PC and the installed drawing software to make the three-dimensional model drawing. For "minimally invasive surgery medical processing software (adopting VTK 5.0 software development)" is the processing software when the hospital carries out orthopedic surgery, this software is improved when the present invention carries out path planning, see figure 2 As shown, the process of processing the initial CT image by the minimally invasive surgery medical processing...

Abstract

The invention discloses a virtual and real resetting registration method of a long bone based on a six-degree-of-freedom parallel connection mechanism, belonging to the technical field of microtrauma surgery. The method comprises the following steps of: carrying out image reconstruction by using data collected by CT (Computed Tomography); and carrying out resetting registration in microtrauma surgery medical treatment software according to a reconstructed virtual image so as to acquire length motion quantity for regulating each branched chain in the six-degree-of-freedom parallel connection mechanism. The invention can overcome the defects of complicating diseases including malunion, post-traumatic arthritis and the like, much blood loss in the operation and incorrect resetting.

Description

technical field [0001] The invention relates to a method for resetting long bones suitable for surgery, more particularly, a method for virtual and real resetting and registration of long bones based on a six-degree-of-freedom parallel mechanism, and belongs to the technical field of minimally invasive surgery. Background technique [0002] During the long bone reduction surgery, the traditional stable internal fixation usually undergoes a large-scale operation, which will destroy the soft tissue around the fracture to varying degrees, and the surgical trauma will also aggravate the necrosis of the early damaged tissue. Periosteal stripping or reaming will disrupt local blood circulation, which will increase the risk of delayed union, nonunion, infection, and even refracture at the fracture site. [0003] For bone fractures, even if "strong fixation" is carried out according to the principle of AO (AO, the abbreviation of arbeitsgemeindschaft furosteosynthesefragen in German...
