Definitions

  • the present invention relates to a camera handpiece for a microoptical probe according to the preamble of claim 1.
  • Such handpieces serve the electronic representation of micro-optically generated images and are increasingly being used in the medical field, but are also used in industrial technology.
  • a handheld microscope for endoscopy is described in DE-199'23'122, in which, according to the reflected light principle, the light is guided through the microscope objective into the object space.
  • the image generated by the lens is digitized by an electronic image sensor, for example a CCP chip, and fed via suitable connections to evaluation electronics for further processing and presentation.
  • This handheld microscope has no possibilities for focusing and / or focal length change.
  • a camera handpiece with the features of claim 1 and in particular with a camera handpiece, which has a motorized miniature drive, which provided for an axial displacement of the focusing optics driver via a miniature transmission with Exzen ⁇ drives.
  • the focusing optics and the driver (connecting rod) are connected to each other via a connecting pin.
  • the miniature gear, the eccentric and the driver are mounted in a gear housing and can be disassembled in a simple Wei ⁇ se.
  • the motor drive can be activated by means of an on-off switch resp. deactivated. This on-off switch is preferably designed as a footswitch.
  • the camera handpiece is dismountable and has a camera housing in which a collection optics cooperating with the focusing optics and a miniature CCD semiconductor element for the image signal generation are housed.
  • the displaceably mounted, focusing optics and the collection optics firmly arranged in the camera housing form a miniature microscope optics.
  • the miniature CCD semiconductor element is an essential part of a video sensor.
  • the camera housing has fastening means for a detachably mountable microoptical probe.
  • the fastening means comprise at least one spring clip mounted pivotably on a plug pin.
  • This spring clamp is provided with a latching element which, upon insertion of a micro-optical probe, engages in a groove provided in the base of this probe.
  • Figure 1 spatial representation of an inventive camera handpiece.
  • FIG. 2 spatial representation of a camera housing with fastening means according to the invention.
  • Figure 3 Spatial representation of the internal structure of an inventive camera handpiece.
  • the camera handpiece 1 shown in FIG. 1 essentially has a camera housing 12, to the front end of which a microscopic probe 2 is fastened. On the back, a transmission cable 13 is attached by means of a union nut 14 on the camera handpiece.
  • the microscopic probe 2 can be plugged with its base 19 in a simple manner and is fastened releasably to the camera housing 12 by fastening means 15 in the form of a snap-fit closure.
  • fastening means 15 have at least one plug pin 16, which engages through the camera housing 12 in a pivot bearing of a spring clip 17.
  • This spring clamp 17 has on the probe side a latching element 18, which engages when inserting the probe 2 in a mounted in the base 19 of the microscopic probe 2 groove.
  • FIG. 3 shows the internal structure of the camera handpiece according to the invention in a three-dimensional exploded view.
  • This internal structure comprises a motor An ⁇ drive 4, which actuates a carrier 5 via a mounted in a transmission housing 9 gear 6 and an eccentric 7.
  • This driver 5 moves a connec tion pin 8 and thus a focused on this probe side focusing optics 3 in the axial direction.
  • a collection optics 10 forms, together with the axially displaceable focusing optics 3 (lens group), a microscope optics which is arranged in a microscope housing 11. It is understood that the optics of the microscopic probe 2 with the help of the provided fastening means 15 to the collection optics 10 can be fastened functionally reliable.
  • This device is suitable for both industrial and medical applications.
  • the advantages of this device are immediately apparent to the person skilled in the art and in particular in the maintenance-friendly construction, in its extraordinary ease of operation and its simple disassembly and assembly, which makes sterilization in an autoclave possible even for inexperienced personnel.
  • the handpiece according to the invention is also suitable for medical treatment with a laser beam or can be used in arthroscopy. Further modifications of the camera handpiece according to the invention can be made by a person skilled in the art without inventive step in order to adapt this handpiece to the particular intended use.

Abstract

L'invention concerne une pièce à main (1) dotée d'une caméra présentant un logement pour la caméra et comprenant une sonde microscopique (12) sur son extrémité avant. Sur son extrémité arrière, un câble de transmission (13) est fixé sur la pièce à main (1) dotée d'une caméra au moyen d'un écrou (14) de liaison. Le logement (12) pour la caméra comporte un logement (11) pour microscope et comprend une commande à moteur (4) qui commande un excentrique (7) par l'intermédiaire d'une transmission (6) montée dans le logement de transmission (9). Ledit excentrique (7) active un entraîneur (5), lequel déplace une broche de raccordement (8) et un système de lentille de mise au point (3) reliés dans le sens axial. Ledit système de lentilles de mise au point (3) pouvant être déplacé interagit avec une optique de collecte 810), de manière à produire un système de lentilles de microscope logé dans le logement du microscope (11).
