Embodiment Construction

[0037] In the following description, numerous details are provided in order to provide a thorough understanding of the invention. However, it will be appreciated by those skilled in the art that the following description relates only to preferred embodiments of the invention and that the invention may be practiced without one or more of these details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0038] In vivo interventional operations in the medical field, such as human body puncture, require accurate positioning in three dimensions and six degrees of freedom. At the same time, due to the arbitrariness of the position of the patient's lesion relative to the doctor's perspective, the positioning of medical devices such as puncture needles needs to be specially optimized for the large-angle rotation of the medical device relative to the camera of the video acquisition device, so as to ensure t...

Abstract

The invention provides an optical marker and a medical device for positioning a medical device outside the body. The optical marker comprises: a body having a recess and / or a protrusion, the recess and / or protrusion is provided with a non-coplanar optical mark for positioning, and the optical mark emerges from the recess Or the surface of the protruding part is visible; and the connecting part connected with the body is used for connecting with the part to be positioned of the medical device. In the optical marker, the body with the optical marker has a non-planar structure, which can increase the recognizable angle of the medical device, and improve the recognition accuracy and stability.

Description

technical field [0001] The present invention relates to the technical field of medical devices, in particular to an optical marker for positioning a medical device and a medical device component. Background technique [0002] In the process of medical clinical practice, it is often necessary to insert medical devices into the human body to perform some kind of interventional operation. For example, microscopic samples of diseased tissues in the human body can be obtained by percutaneous extracorporeal puncture. At present, in the field of diseases based on the natural orifice of the human body, such as cardiovascular, digestive, respiratory and other fields, there are mature device solutions that can meet clinical needs. However, if the lesion is not directly connected to the natural orifice, a surgical channel needs to be established. In this case, minimally invasive interventional operations will be limited by surgical positioning and navigation. The distal end of the m...
