Embodiment Construction

[0124]As used herein, the terms "endoscope" and "arthroscopic" are intended to be used interchangeably and to give their broadest interpretations, with each term denoting an instrument with the ability to be inserted into an otherwise Elongated sections for visual inspection, diagnostic and / or therapeutic or prosthetic purposes in spaces that are difficult to access by minimally invasive means. In the field of medical or veterinary practice, such spaces may include body or organ cavities, joint spaces, tissue planes, or other body structures. The instrument can also be used in many non-medical (e.g., industrial) applications, such as borescopes, where the diameter of the insertion portion (flexible or rigid) of the visualization instrument needs to be minimized, or where a rigid borescope must operate within the space Too restrictive to allow the use of an actively flexible distal segment.

Abstract

An endoscope comprises a handle and a shaft with an optical housing at the distal end of the shaft enclosing a camera sensor positioned so that its optical axis is at an angle with respect to a rotational axis of the shaft. The camera sensor is rotatable with the shaft relative to a proximal housing of the handle. A rotation sensor in the handle detects the rotational angle of the camera sensor with respect to the proximal housing. A processor can correct the angular orientation of an image from the image sensor, converting of a rotating variable field of view to a translating variable field of view. A processor can apply variable smoothing of the rotation of the displayed image so that smoothing during rotational deceleration is greater than smoothing during rotational acceleration. The shaft may be enclosed in a trocar that allows for a space between the shaft and trocar that can be used to carry irrigation fluid to or from a space at the end of the shaft.

Description

technical field [0001] The present disclosure relates to endoscopic instruments for viewing and working in relatively inaccessible spaces; and in some aspects to endoscopes for operating in confined anatomical spaces within the body using endoscopes or arthroscopes, etc. instrument. Background technique [0002] The use of endoscopic instruments in medicine, which allow remote viewing and manipulation in inaccessible spaces, is well established. These devices are also useful in the automotive, aerospace, plumbing, electronics, and many other industries. In the field of medical or veterinary practice, endoscopy or arthroscopy is commonly used to view or treat anatomical areas when minimal or undesired incisions are desired, or to avoid disturbing nearby tissue. For example, in orthopedics, the condition of a joint such as a knee or shoulder can be obtained using one or more arthroscopic instruments introduced into the joint through one or more small skin incisions. These d...
