AI Technical Summary

Technical Problem

Conventional cannulas require multiple medical personnel to handle electrical stimulation and ultrasound imaging simultaneously, leading to cumbersome operations and increased costs due to the need for separate handling of fluid control and cannula positioning.

Method used

A modular cannula system with a control clip and contact clip that allows for single-handed operation, integrating electrical stimulation and ultrasound imaging, enabling simultaneous control of fluid supply, aspiration, and cannula positioning through a single handgrip.

Benefits of technology

Enhances procedural safety and efficiency by optimizing puncture accuracy and reducing the need for multiple operators, while allowing for cost-effective reuse of components.

Abstract

To provide an improved cannula from which detects of known cannulae have been advantageously removed, and which effectively achieves both easy operation by a medical care worker and advantages of production of individual components and cost for reuse.SOLUTION: There is provided a cannula (1) comprising: a cannula body which has a cannula pipe (11) and an attachment (10) attached to a proximal end of the cannula pipe (11); and a control clip (30) which comprises a fixing body (31) including at least one operation element (35, 36). The control clip (30) can be attached to the attachment from its side for forming a first structure stage (I). The invention also relates to a cannula body, a contact point clip (20), and a control clip (30) for the cannula (1) according to the present invention.SELECTED DRAWING: Figure 3
