Disclosed is a dental implant handpiece, comprising an implant handpiece body (1), and a drill bit (2) disposed on the implant handpiece body (1). The implant handpiece body (1) is further provided with an image collector disposed close to the drill bit (2) and configured to acquire images of locations in the vicinity of the drill bit (2) in an oral cavity. In a whole treatment process, a dentist is free of double-handed operation and only needs to hold the dental implant handpiece with one hand. During the treatment process, images near the drill bit (2) are acquired in real time, thus the treatment situation is controlled in real time when each treatment action is executed, and the position and angle of the drill bit (2) may be adjusted at any time according to the images acquired by the image collector.

An endoscope stereo imaging device includes an endoscope lens assembly and an imaging module. The imaging module includes first, second and third lens assemblies, a beam splitter, first and second image sensors and a micro lens array. A light beam from the endoscope lens assembly is transmitted to the beam splitter after passing through the first lens assembly and is split into first and second portions of the light beam. The first portion light beam is transmitted to the first image sensor via the second lens assembly and forms a two-dimensional image. The second portion light beam is transmitted to the second image sensor via the third lens assembly and the micro lens array sequentially and forms a first three-dimensional image.

Surgical visualization systems and related methods are disclosed herein, e.g., for providing visualization during surgical procedures. Systems and methods herein can be used in a wide range of surgical procedures, including spinal surgeries such as minimally-invasive fusion or discectomy procedures. Systems and methods herein can include various features for enhancing end user experience, improving clinical outcomes, or reducing the invasiveness of a surgery. Exemplary features can include access port integration, hands-free operation, active and/or passive lens cleaning, adjustable camera depth, and many others.

An imaging device includes a processor. The processor, in a manual focus mode, sets a focus evaluation area to have a larger size than the focus evaluation area set in an auto focus mode, generates assist information assisting adjustment of the in-focus object plane position based on a focus evaluation value obtained from an image of the focus evaluation area, and outputting the assist information to a display section.

Scopes such as medical imaging camera head devices and methods are provided using light captured by an endoscope system or other medical scope or borescope. At least one polarizing optical element manipulates the polarization properties of image light. The manipulated image light is focused on an image sensor including polarizers for each pixel. Multiple images are produced based sets of pixels having the same orientation of polarizer. The resulting images are combined with high dynamic range techniques.

In a minimally invasive surgical system, an image capture unit includes a prism assembly and sensor assembly. The prism assembly includes a beam splitter, while the sensor assembly includes coplanar image capture sensors. Each of the coplanar image capture sensors has a common front end optical structure, e.g., the optical structure distal to the image capture unit is the same for each of the sensors. A controller enhances images acquired by the coplanar image capture sensors. The enhanced images may include (a) visible images with enhanced feature definition, in which a particular feature in the scene is emphasized to the operator of minimally invasive surgical system; (b) images having increased image apparent resolution; (c) images having increased dynamic range; (d) images displayed in a way based on a pixel color component vector having three or more color components; and (e) images having extended depth of field.

A wafer lens array includes a wafer lens formed by arranging a plurality of plate members on a plane, each plate member including a first window configured to allow light for forming an optical image to pass through, a first light-shielding portion formed on an outer circumference of the first window and a second window formed on an outer circumferential side of the first light-shielding portion and configured to allow illumination light to pass through, and the wafer lens in plurality are coaxially layered and the layered wafer lenses are bonded and fixed together in a region of the second window.
