Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] See figure 1 As shown, a computer-aided intramedullary nail distal locking system of the present invention is composed of a positioning frame 1, a C-arm 2, a computer 3 and image control operation software, and an X-ray camera device 5 on the C-arm 2 collects images Afterwards, it is transmitted to the computer 3 via the video data line, and after calculation and processing by the image control operation software to determine the surgical path, the locking nail is fixed on the intramedullary nail through the guide hole 208 on the positioning frame 1 for surgery.

[0019] In the present invention, first utilize the irradiation of the X-ray light source 4 on the C-arm 2 to form an image on the imaging plane, then, utilize the video capture card in the computer 3 to import the image into the control software through the video data line , c...

Abstract

This invention discloses a computer assistant far end locking system of nail in marrow, including C-typed arm, positioning frame, computer and software of image controlling operation. The image collected by the X-ray imaging device on the C-type arm is transmitted by visual data line to the computer and calcualted and processed by the software of image controlling operation so as to determine the route of the operation, then the operation can be performed. The invention combines a plural subjects and technologies such as medicine, mechanics, computer visual sense and digital image process, etc, achieves the key technique of measurement of position of nail in marrow using single image and simplifies complicated operating process of fixing the nail in marrow in pure mechanical method.

Description

technical field [0001] The invention relates to a medical device, in particular to an intramedullary nail distal-end locking system for assisting doctors in performing bone surgery by means of a computer, its control operating software and a positioning frame. Background technique [0002] At present, fracture surgery has developed from traditional Chinese medicine bone grafting to modern central fixation such as intramedullary nailing. The healing time of surgery is getting shorter and shorter, and the quality requirements of surgery are getting higher and higher. In terms of technology, the most difficult thing to deal with in the current intramedullary nail operation is the fixation of the distal keyhole of the intramedullary nail. When the intramedullary nail is driven into the bone marrow cavity, the doctor must be able to use a locking nail with a diameter of 4mm. Find a hole with a diameter of 4.5mm on the intramedullary nail across the skin and...
