Abstract
Endoscopic tools or instruments having one or more side-deployable snare loop tools are provided. Loop wire tools connected by cables to proximal controlling handles are introduced though side openings in the tools which are located proximal to the distal end of the tools which may also include a soft, blunt tip designed to rest against a body cavity wall for stability. Side introduction of the wire loop tools into a human cavity allows for angulation and positioning favorable to perform endoscopic intervention, particularly when dealing with elongated foreign bodies or impacted food in the esophagus.
Claims16
An endoscopic tool for use with an endoscope, comprising:
- a proximal portion and a distal portion connected by a middle portion and covered in a flexible sheath and having a longitudinal axis running therethrough;
- the proximal end having a control member;
- the middle portion connected to the proximal end and having a channel therethrough;
- the distal portion having a blunt tip and an opening transverse to the longitudinal axis and operationally connected to the channel;
- and
- a wire loop tool disposed in the channel and having a proximal end, a control cable, and a loop end, the proximal end operationally connected to the control member such that extending the wire loop tool extends the loop end through the distal portion opening transverse to the longitudinal axis.
An endoscopic tool for use with an endoscope device, comprising:
- an elongated generally tubular tool body having a proximal and distal end and a longitudinal axis running therethrough;
- a control member disposed at a proximal end of the tool for controlling the tool;
- a wire loop tool having a proximal end, a control cable portion, and a wire loop end, the proximal end being operationally connected to the control member;
- a tubular channel disposed along the longitudinal axis of the tool, the wire loop tool disposed within the channel such that the wire loop end is within the channel when in a fully retracted position and extends from the channel when in an extended position;
- a blunt tip portion coupled to the distal end of the tool body;
- and
- an opening disposed in the side of the tubular channel and arranged such that the wire loop extends from the opening transverse to the longitudinal axis of the tool when in the extended position.
