Abstract: An assembly of cannula and endoscope and dissection tip facilitate surgical procedures at remote surgical site in tissue of a patient. Relative rotation of the cannula about the endoscope from clamped rotational fixation of the cannula and endoscope is made possible by flexing a resilient clamping segment, and such relative rotation promotes convenient positioning of an eccentric tissue-dissecting tip about a vessel being harvested from within tissue of a patient. Color tinting of the tip or color-tinted illumination of tissue at a remote surgical site enhances contrasting visualization through the tip via the endoscope among the tissue types encountered at the surgical site within a patient. A tool bridge or lateral support mounts to a more rigid component such as an endoscope that extends from the proximal end of a cannula to support a more flexible surgical instrument also extending from the proximal end of the cannula.

Abstract: A speculum according to the invention comprises two parts, an outer member (1) and an inner member (2). The outer member (1) comprises a tubular body (3) having an anterior end (4) with an opening (6) and a posterior end (5) with an opening (7). An elongate slot (11) is formed in the side wall (12) of the tubular body (3), extending from the opening (7) at the posterior end (5) towards the anterior end (4). The inner member (2) of the speculum comprises a cup-shaped body (13) having an anterior end (14) formed as a plug (16) and a posterior end (15) with an opening (17). An elongate key member (18) is formed in the side wall (19) of the cup-shaped body (13), extending from the opening (17) at the posterior end (15) towards the anterior end (14). The speculum is assembled by inserting the inner member (2) within the outer member (3) and aligning the key member (18) with the elongate slot (11). When the spectrum has been inserted within a body cavity, the inner member (2) may be removed and the outer member (3) may be rotated to align the elongate slot (11) with a site of interest in the cavity wall, thus allowing a user to examine tissue in the body cavity or to have access to sites of required surgical procedures.

Abstract: An operational remote controller integrates a joystick for bending a bending portion of an inserted portion in an endoscope. A bending lever stands on the joystick. For every automatically returning of the bending lever to a neutral position, a CPU of the operational remote controller detects the neutral position and sets an insensitive band within a predetermined range of the neutral position. Thus, the insensitive band can be set within a relatively narrow range irrespective of variation of neutral positions. The CPU supplies positional information of the bending lever to a control circuit for controlling a motor drive circuit. The control circuit controls a motor drive circuit based on the supplied positional information, and the motor drive circuit drives a motor to bend the bending portion of the inserted portion.

Abstract: An endoscope comprises a plurality of members constituting the endoscope, and parts-bonded sections each having at least members thereof bonded together using an adhesive. The temperatures of thermal destruction at which the adhesives included in the parts-bonded sections are thermally destroyed are made equal to or higher than the maximum temperature attained during a high-pressure steam sterilization process. At the same time, the temperatures of thermal destruction are made equal to or lower than the heat-resistance temperatures above which members bonded using the adhesives or members located near the bonded members included in the parts-bonded sections fail to resist heat.
