Abstract

PURPOSE:To certainly separate the leading end of a treatment member from a living body at the time of the stop of suction operation by blocking a suction operating opening and closing valve and opening a negative pressure release valve to send a compressed fluid in a suction hole for a definite time. CONSTITUTION:When an operating switch 21 is operated, a suction operating opening and closing valve 11 is opened and an opening valve 16 is closed and the sucking action of a suction pump 5 is transmitted to the suction hole provided to the leading end of the vibration transmitting member 2 of a handpiece 1 while a negative pressure release valve 19 is closed. In excised tissue piece, broken pieces of a calculus, body fluids or a perfusate are sucked from the suction hole to be collected in a suction bin 6 through a suction route 4. The ultrasonic vibrator of the handpiece 1 is driven and tissue is excised by the leading end of the vibration transmitting member 2 or a calculus is broken. When the operating switch 21 is turned OFF, the suction operating opening and closing valve 11 is closed and the passage 4a of the suction route 4 is blocked and sucking action is stopped. Further, the opening valve 16 is opened to begin to suck the atmosphere. Further, the negative pressure release valve 19 is opened to continue an open state for a definite time. Therefore, the negative pressure of the ultrasonic transmitting member 2 is eliminated to separate said member 2 from a living body 3.

5 and 6 show a second embodiment of the invention. In this embodiment, a rotary solenoid 25 is used in place of the push-pull solenoid 12 that opens and closes the suction operation on-off valve 11. That is, the rotary solenoid 25 causes the plate-shaped presser body 26 to select the solid line position and the dotted line position shown in FIGS.
When 6 is in the position shown by the solid line, the elastic tube 15 forming the passage 4a of the suction system 4 is crushed to block the passage 4a. Further, at the position shown by the dotted line, the elastic tube 15 is opened to open the passage 4a. This opens and closes the passage 4a. Incidentally, if the elastic tube 15 is held down by the plate-shaped holding body 26 in a line along its axial direction as shown in FIG. 6, the torque of the rotary solenoid 25 can be reduced. Other structures and functions are the same as those of the first embodiment.

Then, in the same manner as above, the plate-shaped presser body 26 is driven to select the solid line position and the dotted line position shown in FIGS. 7 and 8,
When the presser body 26 is in the position shown by the solid line, the elastic tube 15 forming the passage 4a of the suction system path 4 is crushed to block the passage 4a. Further, at the position shown by the dotted line, the elastic tube 15 is released to open the passage 4a. The other configurations are the same as those of the second embodiment.

9 and 10 show a fourth embodiment of the present invention. This fourth embodiment is basically constructed in the same manner as the first embodiment, but in particular, the suction pump 5 is
The operation is also controlled by the control circuit 20. That is, as shown in the time chart of FIG. 10, even after the treatment operation is stopped, the negative pressure release valve 19 is opened for a certain period of time from the time of the stop, and after this one negative pressure release valve is closed again, the suction pump is closed. 5 stops.

Therefore, even if the treatment operation is stopped and the suction operation on-off valve 11 is closed, the negative pressure release valve 19 is opened, the pressurization conduit 18 is released, and the suction pump 5 continues to operate. Air at a predetermined pressure (slightly higher than the pressure inside the body cavity) is introduced from the exhaust port 5b of the suction pump 5 to the suction hole side of the hand piece 1 through the pressurization conduit 18. Therefore, even if the living body 3 is suctioned into the opening at the tip of the suction hole of the ultrasonic transmission member 2, the negative pressure is eliminated and the living body 3 leaves.

FIG. 11 shows a fifth embodiment of the present invention. In this fifth embodiment, in the configuration of the first embodiment described above, a check valve 31 is inserted between the suction system path 4 and the negative pressure release valve 19 in the middle of the pressurization conduit 18, It is made to flow only from the pressurizing pipe line 18 side to the suction system line 4 side. Furthermore, a check valve 33 is provided in the pipe line 6b which branches from the middle of the suction system line 4 and is provided with the opening valve 16, and is located closer to the suction line 4 side than the opening valve 16. The flow from the 4th side was blocked.

However, by providing the check valves 31 and 33, even if bodily fluids, blood, biological tissue, etc. flow from the suction system path 4 side to the negative pressure release valve 19 or the release valve 16 side during operation, this will not occur. This produces an effect of blocking the negative pressure and prevents it from flowing into the release valve 16 or the negative pressure release valve 19. Therefore, malfunction and corrosion of the negative pressure release valve 19 and the release valve 16 can be prevented. Further, it is safe because the liquid to be sucked does not flow into the pressurizing conduit 18 side. moreover,
The life of the release valve 16 and the negative pressure release valve 19 can be extended.

In this configuration, when the suction operation on-off valve 11 is shut off and the suction operation is stopped, the negative pressure release valve 19 is released for a certain period of time, and the suction system path 4 on the handpiece 1 side from the suction operation on-off valve 11 is opened. The part is released to the atmosphere, and the pressure protection in the suction system path 4 part on the side of the handpiece 1 is released. The time for one negative pressure release valve to release is set to be sufficient time for the pressure protection to be released, as in the case of the above-described embodiment.
