Abstract
An exhaust tool (50) includes: a flexible body portion (51) extending over substantially an entire length of a cylindrical shaft (30, 90) of an incision energy device (e.g., ultrasonic coagulation incision device 10 or electrocautery device 80) having an energy generation portion (32) for incision provided at a tip thereof; a pair of holding portions (52) provided to the body portion (51) and configured to hold the cylindrical shaft (30, 90); and a flow path formation portion (54) forming therein a flow path (56) for mist generated from the energy generation portion (32). The exhaust tool (50) is allowed to be attached/detached to/from the cylindrical shaft (30, 90) by the pair of holding portions (52) being opened through bending of the body portion (51).
Claims8
An exhaust tool to be attached to a cylindrical shaft of an incision energy device having an energy generation portion for incision provided at a tip thereof, the exhaust tool comprising:
- a flexible body portion configured to extend over substantially an entire length of the cylindrical shaft;
- the flexible body portion including a pair of holding portions configured to hold the cylindrical shaft, the pair of holding portions extending over substantially the entire length of the cylindrical shaft;
- and
- a flow path formation portion forming therein a flow path for mist generated from the energy generation portion, wherein
- the exhaust tool is configured to be attached/detached to/from the cylindrical shaft by the pair of holding portions being opened through bending of the flexible body portion.
An exhaust system comprising:
- an incision energy device having an energy generation portion for incision provided at a tip thereof;
- and
- an exhaust tool to be attached to a cylindrical shaft of the incision energy device, wherein the exhaust tool includes
- a flexible body portion,
- the flexible body portion including a pair of holding portions configured to hold the cylindrical shaft, the pair of holding portions extending over substantially the entire length of the cylindrical shaft, and
- a flow path formation portion forming therein a flow path for mist generated from the energy generation portion, and
- the exhaust tool is configured to be attached/detached to/from the cylindrical shaft by the pair of holding portions being opened through bending of the flexible body portion.
An exhaust tool to be attached to a cylindrical shaft of an incision energy device having an energy generation portion for incision provided at a tip thereof, the exhaust tool comprising:
- a flexible body portion configured to extend over substantially an entire length of the cylindrical shaft;
- the flexible body portion including a pair of holding portions configured to hold the cylindrical shaft;
- and
- a flow path formation portion, wherein the exhaust tool is configured to be attached/detached to/from the cylindrical shaft by the pair of holding portions being opened through bending of the flexible body portion, and, when the exhaust tool is attached to the cylindrical shaft, the flow path formation portion and the cylindrical shaft define a flow path for mist generated from the energy generation portion, the cylindrical shaft completing a boundary of the flow path with the flow path formation portion.
