Definitions

  • the rotation feedback mechanism includes a gyroscope
  • the operating portion includes a handle housing and an inner tube located in the handle housing and rotatable together with the handle housing, the inner tube defining the inner space , the vacuum feedthrough is welded to the inner tube at its proximal end to seal the interior space, the gyroscope is secured to the inner tube within the interior space and is configured to sense The rotation direction and rotation angle of the handle housing.
  • Endoscope 1000a includes a distal portion or imaging portion 100a and a proximal portion or handle portion 200a, as shown in FIG. 4 .
  • the imaging portion 100a may be inserted into a patient to image the patient's body.
  • the length of the imaging portion 100a is omitted in FIG. 4, and can be set according to actual needs.
  • the handle portion 200a serves as an operating portion for the operator to hold and remotely operate the imaging portion, eg, extending or rotating the distal imaging portion 200a, in order to provide an image or video of the desired site.
  • the motor 8a is attached to the inside of the inner tube 7a via a fixing ring 9a.
  • the output shaft of the motor 8a is connected to the rotary tube 3a, so that the motor 8a can drive the rotary tube 3a to rotate and drive the camera 2a to rotate.

Abstract

L'invention concerne un endoscope (1000). L'endoscope (1000) comprend une partie imagerie (100) au niveau d'un côté distal et une partie de fonctionnement (200) au niveau d'un côté proximal ; la partie imagerie (100) est utilisée pour une imagerie à l'intérieur du corps d'un patient et comprend une caméra (2) ; la partie de fonctionnement (200) est fixée de manière fonctionnelle à la partie imagerie (100) de telle sorte que la partie imagerie (100) peut tourner conjointement avec la rotation de la partie de fonctionnement (200) ; la partie de fonctionnement (200) définit un espace interne. Un élément de traversée sous vide (10) est soudé à la partie de fonctionnement (200) au niveau de l'extrémité proximale de la partie de fonctionnement (200) pour sceller l'espace interne et fournir une connexion électrique ou une connexion par signal entre l'espace interne et l'extérieur.
