摘要： PROBLEM TO BE SOLVED: To provide a medical apparatus capable of cutting off biological tissue at a stable depth irrespective of a moving speed of a nozzle.SOLUTION: A medical apparatus injects pulsed liquid from a nozzle 108 provided to a leading end of a liquid injection tube 106, and causes a marking member to be mounted at a predetermined position of a liquid injection section or the liquid injection tube 106 and captures images of the liquid injection section by cameras 150 from at least two directions at predetermined time intervals. Further, the medical apparatus detects a moving speed of the nozzle 108 by detecting a position of the marking member from the images captured, and increases a driving frequency of a piezoelectric element 112 when the moving speed of the nozzle 108 is increased or decreases the driving frequency of the piezoelectric element 112 when the moving speed of the nozzle 108 is decreased. Thus, a number of times of injection of the liquid for each unit length can be caused not to vary depending upon the moving speed of the nozzle 108. Accordingly, the medical apparatus can cut off biological tissues at a stable cut-off depth.

摘要： PROBLEM TO BE SOLVED: To promptly switch a state in which a liquid is jetted from a nozzle and a state in which jetting is stopped.SOLUTION: A tube on the inner side of a double tube includes a nozzle on the distal end thereof and is used as a liquid jetting tube, a tube on the outer side is used as a suction tube forming a suction flow path between the suction tube and the liquid jetting tube, and the liquid is sucked from the suction flow path. Also, a distal end member deformable by external force is attached to the distal end of the suction tube, and at the distal end of the distal end member, a passing port is provided on a position offset from a position where the liquid jetted from the nozzle passes through. In such a manner, the liquid from the nozzle passes through the passing port and is jetted to the outside only when the distal end member is deformed by the external force, and the liquid jetted from the nozzle is sucked through the suction flow path without passing through the passing port when the distal end member is not deformed. As a result, the state in which the liquid is jetted and the state in which the jetting is stopped are promptly switched.

摘要： PROBLEM TO BE SOLVED: To provide a liquid ejecting apparatus in the liquid chamber of which bubbles are hard to accumulate so as to enable the liquid to be stably ejected.SOLUTION: The liquid ejecting apparatus 10 is structured as follows: the liquid chamber 110 is formed by winding or folding a tube 120 having an inlet port 110a and an outlet port 110b in a spiral manner between the inlet port 110a and the outlet port 110b; and the tube 120 is pressed to reduce the volume of the liquid chamber 110 by driving a piezoelectric element 112. According to such a structure, the liquid in the liquid chamber 110 is pressurized by reducing the volume of the liquid chamber 110, and the pressurized liquid can be ejected from a nozzle 102 communicating with the outlet port 110b of the liquid chamber 110 in a pulse mode. When filling the liquid chamber 110 with the liquid, the flow of the liquid in the liquid chamber 110 is restricted along the tube 120 so as to inhibit accumulation of air bubbles in a portion where the flow of the liquid is slow, and hence the air bubbles in the liquid chamber 110 can be discharged quickly.

摘要： PROBLEM TO BE SOLVED: To effectively penetrate a blood clot and the like with a pulsation flow while removing the whole of blood clot and the like by emitting a jet of a fluid widely. SOLUTION: An auxiliary jet orifice is opened to a direction different from a direction of a jet orifice emitting a pulsation flow, and it is connected to an auxiliary fluid path which is different from a connection fluid path connected to the jet orifice. The fluid is continuously emitted from the auxiliary jet orifice by continuously sending the fluid to the auxiliary fluid path. The result is that the pressure of pulsation flow does not decrease because of the auxiliary jet orifice, and the cutting performance of the pulsation flow is kept while the fluid can be emitted from the auxiliary jet orifice within the area where the pulsation flow can not be emitted. Then, the auxiliary jet orifice can keep the cutting performance by continuously emitting the jet of the fluid even when the pressure of the fluid disperses and decreases by emitting the jet of the fluid widely. As a result, the blood clot and the like can be penetrated effectively by the pulsation flow while the whole of blood clot and the like can be removed by emitting the jet of the fluid widely.
