Abstract

Abstract A medical treatment apparatus utilizing ultrasonic vibrations includes an ultrasonic vibration generator having an ultrasonic oscillator with a first through-hole formed therein. A liquid supply device is communicated with one end of the first through-hole, and a second through-hole of a horn mounted on the ultrasonic vibration generator is communicated with the other end of the first through-hole. A transmission member for transmitting ultrasonic vibrations is connected to a front portion of the horn, and a tube member is arranged to surround the transmission member. A passage formed between the tube and transmission members is coupled to the second through-hole by coupling members, and the transmission member is slightly protruded from the distal end of the tube member. Therefore, a sufficient amount of the liquid supplied from the liquid supply device can be flowed through the passage.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 184 words
A medical treatment apparatus for use in combination with an endoscope including an insertion portion having a channel, said apparatus comprising: ultrasonic vibration generation means including an oscillator having means for defining a first through-hole; liquid supply means in communication with one end of the first through-hole; a horn having means for defining a second through-hole, said second through-hole being in communication with the other end of the first through-hole, said horn being coupled to, and adapted to amplify vibration generated by, said ultrasonic vibration generation means; a transmission member connected to said horn for transmitting the amplified vibration, said transmission member having means defining an internal hole extending axially therethrough and in communication with said second through-hole for accommodating liquid flow from the liquid supply means in an outward direction; a tubular member surrounding said transmission member, thus defining a passage therebetween, and said transmission member protruding from a distal end of said tubular member; and coupling means for communicating said passage with the second through-hole for supplying liquid from the liquid supply means to flow through said passage in said outward direction.
Claim 2
Dependent Claim 184 words
A medical treatment apparatus for use in combination with an endoscope including an insertion portion having a channel, said apparatus comprising: ultrasonic vibration generation means including an oscillator having means for defining a first through-hole; liquid supply means in communication with one end of the first through-hole; a horn having means for defining a second through-hole, said second through-hole being in communication with the other end of the first through-hole, said horn being coupled to, and adapted to amplify vibration generated by, said ultrasonic vibration generation means; a transmission member connected to said horn for transmitting the amplified vibration, said transmission member having means defining an internal hole extending axially therethrough and in communication with said second through-hole for accommodating liquid flow from the liquid supply means in an outward direction; a tubular member surrounding said transmission member, thus defining a passage therebetween, and said transmission member protruding from a distal end of said tubular member; and coupling means for communicating said passage with the second through-hole for supplying liquid from the liquid supply means to flow through said passage in said outward direction.
Claim 3
Dependent Claim 31 words
A treatment apparatus according to claim 1, wherein said transmission member comprises a plurality of thin tubular members each having means for defining an internal hole connected to the second through-hole.
Claim 4
Dependent Claim 60 words
A treatment apparatus according to claim 2, wherein said coupling means comprises: a plurality of short tubes positioned at intervals around an outer periphery of said transmission member; and a connecting member having means defining a through-hole in which proximal end portions of said transmission member and said short tubes are stored, and which is detachably mounted on said horn.
Claim 5
Dependent Claim 33 words
A treatment apparatus according to claim 3, wherein said connecting member includes means defining a water supply opening formed on a distal end portion thereof and adapted to communicate with said second through-hole.
Claim 6
Dependent Claim 103 words
A treatment apparatus according to claim 1, wherein said transmission member is received in the channel of the insertion portion of said endoscope, which has a bent portion, and a distal end portion of said transmission member protrudes from the distal end of said insertion portion by a predetermined length, and respective lengths of said transmission member and the insertion portion of said endoscope are such that when said transmission member is oscillated at a predetermined resonant frequency, a portion of said transmission member which engages an inner wall of said channel at said bent portion substantially coincides with a node of vibration.
