Claims (3)
前記直線上に配置され、前記直線に沿って移動するバランサー部と、
動力源から供給される動力によって、前記破壊部と前記バランサー部とを同一の前記直線上で反対方向に移動させる移動機構と、
を備えることを特徴とする手術器具。 A destructive part that destroys biological tissue by moving along a straight line
A balancer unit disposed on the straight line and moving along the straight line;
A moving mechanism that moves the destruction part and the balancer part in the opposite direction on the same straight line by power supplied from a power source;
A surgical instrument comprising:
前記動力源である圧縮気体発生部が発生させる圧縮気体が導入される気体室をさらに備え、
前記移動機構は、
前記気体室の内壁の一部を成すと共に、前記気体室内に前記圧縮気体が導入されることで前記直線に沿う第１方向に前記破壊部と共に移動する第１動力伝達部と、
前記気体室の内壁のうち前記第１動力伝達部と異なる部位を成すと共に、前記気体室内に前記圧縮気体が導入されることで前記第１方向とは反対の第２方向に前記バランサー部と共に移動する第２動力伝達部と、
を備えることを特徴とする手術器具。 The surgical instrument according to claim 1,
Further comprising a gas chamber into which a compressed gas generated by the compressed gas generation unit as the power source is introduced;
The moving mechanism is
A first power transmission unit that forms part of the inner wall of the gas chamber and moves together with the destruction unit in a first direction along the straight line by introducing the compressed gas into the gas chamber;
The inner wall of the gas chamber forms a part different from the first power transmission unit and moves with the balancer unit in a second direction opposite to the first direction by introducing the compressed gas into the gas chamber. A second power transmission unit,
A surgical instrument comprising:
前記動力によって移動した前記破壊部に接触することで前記破壊部の移動量を規制する第１規制部と、A first restricting portion for restricting the amount of movement of the destruction portion by contacting the destruction portion moved by the power;
前記動力によって移動した前記バランサー部に接触することで、前記バランサー部の移動量を規制する第２規制部とを備え、A second regulating unit that regulates a movement amount of the balancer unit by contacting the balancer unit moved by the power;
前記破壊部が前記第１規制部に接触するタイミングと、前記バランサー部が前記第２規制部に接触するタイミングとが同時であることを特徴とする手術器具。The surgical instrument characterized in that the timing at which the destruction part contacts the first regulation part and the timing at which the balancer part contacts the second regulation part are simultaneous.
