Definitions
- the present invention relates to a probe unit, a treatment tool, and a treatment system used for treating a living tissue using ultrasonic vibration.
- the treatment target site should be marked in advance.
- a treatment instrument disclosed in Japanese Patent Application Laid-Open No. 2004-237100 can be used as another instrument.
- the flow of treatment in this case is to perform marking by accessing a treatment target site through an introduction conduit (port) while observing a treatment target site with an endoscope or the like. Thereafter, the treatment tool for marking is extracted from the introduction conduit, the treatment tool for treating the treatment target is placed in the introduction conduit, the site to be treated is accessed, and treatment is performed according to the marked position.
- a treatment tool that performs marking in order to define a site to be treated, and a treatment tool that has a probe for treating the marked treatment object are replaced from one introduction conduit. Is going. For this reason, it takes time to perform the operation of treating the treatment target.
- An object of the present invention is to provide a probe unit, a treatment tool, and a treatment system that can mark a site to be treated and can treat the marked treatment target.
- a probe unit used to treat a treatment target site of a biological tissue by ultrasonic vibration includes a vibration transmission unit that transmits ultrasonic vibration from a proximal end side to a distal end side; A probe having a treatment part disposed on the distal end side of the vibration transmission part and capable of treating the treatment target site by ultrasonic vibration transmitted through the vibration transmission part, and protruding from the treatment part of the probe and the living body And a marking portion that can be marked so as to define the treatment target site in the tissue.
- FIG. 1 is a schematic view showing a treatment system according to the first embodiment.

- FIG. 3A is a schematic side view showing a hook-type treatment portion and a marking portion of the probe unit of the treatment tool of the treatment system according to the first embodiment.
- FIG. 3B is a schematic top view showing a hook-type treatment portion and a marking portion of the probe unit of the treatment tool of the treatment system according to the first embodiment.
- FIG. 4 is a schematic diagram illustrating a state in which marking is performed so as to define a treatment target site of a biological tissue using the treatment system according to the first embodiment.
- FIG. 5A is a schematic side view showing a hook-type treatment portion and a marking portion of the probe unit of the treatment tool of the treatment system according to the first modification of the first embodiment.
- FIG. 5B is a schematic top view showing a hook-type treatment portion and a marking portion of the probe unit of the treatment tool of the treatment system according to the first modification of the first embodiment.
- FIG. 6 is a schematic perspective view showing a rake type treatment portion and a marking portion of the probe unit of the treatment tool of the treatment system according to the second modification of the first embodiment.
- FIG. 7 is a schematic perspective view showing a curette type treatment portion and a marking portion of the probe unit of the treatment tool of the treatment system according to the third modification of the first embodiment.
- FIG. 8 is a schematic partial longitudinal sectional view showing a treatment system according to the second embodiment.
- FIG. 9A is a schematic side view showing a hook-type treatment portion of a probe unit of a treatment tool of a treatment system according to a second embodiment and a marking portion in a state of protruding from the distal end of the treatment portion.
- FIG. 9B is a schematic top view showing the hook-type treatment portion of the probe unit of the treatment tool of the treatment system according to the second embodiment and the marking portion in a state of protruding from the distal end of the treatment portion.
- a treatment system 10 includes a treatment instrument 12 used for treating a living tissue, a power supply unit (controller) 14, and a switch unit 16 such as a foot switch or a hand switch.
- the treatment instrument 12 and the power supply unit 14 are connected via a cable 18.
- the cable 18 transmits / receives a signal from the switch unit 16 to the power supply unit 14, and supplies power controlled by the power supply unit 14 to an ultrasonic transducer 52 described later of the treatment instrument 12.
- the cable 18 extends from the cable protector 18 a at the proximal end of the treatment instrument 12, and a connector (not shown) at the distal end of the cable 18 is detachable from the power supply unit 14.
- the switch unit 16 is described as a hand switch disposed on the grasping unit 22 of the treatment instrument 12, but a foot switch (not shown) connected to the power supply unit 14 is also preferably used. .
- the treatment instrument 12 includes a grip portion 22 that is gripped by a user, an ultrasonic transducer unit 24, and a probe unit 26.
- the treatment instrument 12 supports the probe unit 26, the ultrasonic transducer unit 24 that transmits ultrasonic vibrations to the probe unit 26, and the ultrasonic transducer unit 24, and the grip portion 22 that is gripped by the user. And have.
- the grip portion 22 has a central axis on the longitudinal axis L defined by the probe unit 26.
- a transducer unit 24, a probe unit 26, and a tubular body (sheath) 30 are disposed with respect to the grip portion 22 with the longitudinal axis L as a center.
- the grip portion 22 has a cylindrical outer case 42 that is preferably electrically insulating.
- the ultrasonic transducer unit 24 is supported inside the outer case 42.
- the vibrator unit 24 expands the amplitude of the ultrasonic vibration generated by the ultrasonic vibrator 52 and the ultrasonic vibrator 52 that generates ultrasonic vibration by supplying appropriate power from the power supply unit 14 shown in FIG. And a conical horn 54. That is, the transducer unit 24 generates ultrasonic vibrations according to the supply of power.
- the ultrasonic transducer 52 is, for example, a BLT type.
- the horn 54 is attached to the male screw 26 a at the base end of the probe unit 26 by a connection screw (female screw) 56.
- the horn 54 includes an outer flange 54 a that protrudes radially outward with respect to the longitudinal axis L of the horn 54.
- the outer flange 54a is in a vibration node position when ultrasonic vibration is transmitted from the ultrasonic vibrator 52.
