Embodiment Construction

[0015] First refer to figure 1 , shows a one-piece curved neck 10 for an articulated ultrasound probe formed from two concentric tubes usually made of metal such as stainless steel. The inner tube 10b fits tightly within the outer tube 10a. Prior to insertion, two longitudinal grooves 12 are formed on opposite sides along the outer length of the tube 10b. These grooves form passages for the control cables that control the articulation of the curved neck as described below. exist Figure 1A The groove 12 is clearly shown in the cross-sectional view of . With the two tubes positioned concentrically, the two tubes are then cut into separate links 11 by laser cutting towards the longitudinal axis of the tubes or by another machining technique. The links are formed to remain movably connected to each other, for example by lobes 14 extending from one link to the next and located on opposite sides of the links. These protrusions and spacing between the links formed by the proces...

Abstract

A bending neck comprising a plurality of pivotally connected hollow links is formed by machining a tube to form individual, pivotally connected links. A second tube may be located inside the first tube and simultaneously machined with the first tube. Grooves are formed on opposite sides of the outer surface of the second tube to provide a passageway for control cables which control the articulation of the links. In a second implementation indentations are formed in the side of the single tube to form ring-like projections into the inner lumen of each link, through which the control cables may pass.

Description

technical field [0001] The present invention relates to ultrasound imaging probes, and more particularly to curved necks for articulated ultrasound probes. Background technique [0002] Several ultrasound probes are designed for imaging from within the body, including catheter probes and transesophageal echocardiography (TEE) probes. In these probes, the imaging transducer is located at the end of the probe, which is usually designed to be articulated by the operator to obtain the desired view. The preferred way of articulating the probe tip, especially in the case of a TEE probe, is by means of the catheter or the distal segment of the gastroscope called the curved neck. The curved neck is formed by a series of links pivotally connected to each other. This enables each link to move slightly relative to its adjoining links and thus allows controllable articulation of the links of the entire segment over large bending angles. Articulation is controlled by cables extending ...
