A system for judging the advancing path of reaming tools in bone reaming surgery

Abstract

The invention discloses a judgment method of a reaming tool advance path in a bone reaming surgery and relates to the technical field of assistance of the bone reaming surgery. The method comprises the following steps: (1) acquiring real-time stress feedback of a reaming tool in a bone reaming surgery process by a sensor; (2) extracting the maximum of the absolute value of stress of the reaming tool in each rotation cycle from stress feedback in m rotation cycles of the reaming tool in the step (1), wherein the value of m is selected according to the required measurement accuracy; (3) processing data acquired in the step (2), and obtaining a real-time function relation between stress and time; and (4) judging an advance path of the reaming tool at the moment by analyzing the characteristicof the function in the step (3). The method can judge the advance path of the reaming tool at the moment in the bone reaming surgery, so that an operation doctor can accurately control the reaming directions and positions and timely adjust deviated reaming directions and positions.

Description

technical field [0001] The invention relates to the technical field of auxiliary bone reaming surgery, in particular to a system for judging the advancing path of a reaming tool in bone reaming surgery. Background technique [0002] In the existing technology, during the operation, the surgical assistance system often measures the accuracy of the position and direction of the medical device through surgical navigation and CT shooting. However, due to individual differences, the accuracy of surgical navigation will vary. At the same time, CT shooting will have a lot of radiation, which is harmful to the human body. In addition, when performing bone reaming surgery, the doctor cannot know whether the advancing path of the reaming tool is correct, because most auxiliary systems do not have a mechanical feedback device, and there is no specific analytical logic and judgment method for mechanical testing. Judging from the above, the operation process cannot get corresponding pro...

[0002] In the existing technology, during the operation, the surgical assistance system often measures the accuracy of the position and direction of the medical device through surgical navigation and CT shooting. However, due to individual differences, the accuracy of surgical navigation will vary. At the same time, CT shooting will have a lot of radiation, which is harmful to the human body

In addition, when performing bone reaming surgery, the doctor cannot know whether the advancing path of the reaming tool is correct, because most auxiliary systems do not have a mechanical feedback device, and there is no specific analysis logic and judgment method for mechanical testing. Judgment on the basis of judgment, the operation process can not get the corresponding prompts or warnings, operation errors will seriously affect the efficiency and effect of the operation
