In the time of the base end part inner peripheral surface of the bottom operating of contacts portion main body 54 of high frequency connecting pin 94, vibrator component guide 96 is installed on the inner peripheral surface of this operating portion main body 54 under status of electrically connecting.At the outer peripheral face of the base end part of this vibrator component guide 96, the C rim bearing that bears coupling collar shown in Figure 2 34 is subjected to parts 98 to be screwed on the inner peripheral surface of operating portion main body 54.Therefore, utilize the C rim bearing to be subjected to parts 98 and guide 96, formed assembly connecting portion 32 bonded oscillator links 99 with vibrator component 16.

The cross section is that L shaped joint 92a utilizes the 5th pin 70e to be installed in the base end part of this guide 96.Joint 92a is given potential energy by certain power, contacts on the outer peripheral face of contact pipe 92 with elastic deformation.The cross section of the leading section of this joint 92a is a U-shaped, and the bottom of U-shaped is designed to the outside near contact pipe 92, and becomes the inboard.Therefore, joint 92a is with the outer peripheral face of outside elastic deformation line contact at contact pipe 92.In such formation, for example, when probe 14 being installed on the operating portion main body 54 of Handleset 22, on contact pipe 92 or positioning element 90, needn't be provided with towards radially outstanding parts.Therefore, in this case, just can not hook the leading section etc. of the handling part 46 of probe 14, and can install easily and reliably.

Above-mentioned high frequency connecting pin 94 is electrically connected with contact pipe 92 by the joint 92a of vibrator component guide 96.In addition, contact pipe 92 is connected by chimeric with positioning element 90, so high frequency connecting pin 94 also is electrically connected with positioning element 90.

So, constituted Handleset 22 (with reference to Fig. 2 A).

As shown in Figure 8, casing assembly 24 has knob 112, casing assembly link 114, insulation tube 116, elongated tubular 118 and front end sleeve 120.

Extend fixed arm 114a, the 114b of a pair of bifurcated with the base end part of link 114 from casing assembly.The base end part of these fixed arms 114a, 114b has formed towards fixed part (the 4th installing mechanism) 114c, the 114d of the outstanding protuberance of radial outside.The above-mentioned shell link 72 of these fixed parts 114c, 114d and Handleset 22 can in conjunction with/throw off.

As Fig. 6 A and shown in Figure 8, formed towards radially inner side outstanding interior protuberance 114e, 114f at the base end part of fixed arm 114a, 114b.As shown in Figure 8, adorning ring spacer 114g at casing assembly with the inboard of link 114.This packing ring 114g contacts nearly on the outer peripheral face of aftermentioned claw assembly with link 126 (with reference to Fig. 9) of above-mentioned claw assembly 26, to guarantee air-tightness.Therefore, under the state that assembles, for example can prevent in the surgical operation under the endoscope the employed abdomen gas that rises from the clearance leakage of casing assembly 24 and claw assembly 26 to handle 56,58 1 sides.

As shown in Figure 8, with the front of link 114 elongated tubular 118 is installed at casing assembly.Leading section at this elongated tubular 118 is formed with a pair of occlusal crib (the 2nd notch) 118a.These occlusal cribs 118a roughly forms L shaped shape.Therefore, occlusal crib 118a has: the part of extending vertically towards base end part from the front end of elongated tubular 118; And, approximately the tilt part of positions of 60 degree of and from this end extend to axle center with respect to elongated tubular 118 vertical with the rear end side end of this part.On these occlusal cribs (the 5th installing mechanism) 118a, combine outer protuberance (the 3rd installing mechanism) 132i, the 132j (with reference to Fig. 8 and Figure 10 B) of arm 132c, 132d of the aftermentioned pawl support unit (service portion support unit) 132 of claw assembly 26 (with reference to Fig. 9).Periphery at the leading section of elongated tubular 118 is disposing the front end sleeve 120 that covers occlusal crib 118a.The front end face of this front end sleeve 120 has edge part outstanding outside the footpath.

With the periphery of link 114 external thread part is set at casing assembly.This external thread part screws togather mutually with the internal thread part that is positioned on the inner periphery of cylindric turn-knob 112.Outer peripheral face at turn-knob 112 forms non slip surface 112a.Periphery at front end sleeve 120 and elongated tubular 118 covers insulation tube 116.Shown in Figure 10 A, the front of insulation tube 116 is connected on the edge part of the front end that is positioned at front end sleeve 120.As shown in Figure 5, the base end part of insulation tube 116 extends to the inner peripheral surface of turn-knob 112.So just constituted casing assembly 24 (with reference to Fig. 2 A).

As shown in Figure 9, claw assembly 26 has claw assembly link 126, driving tube (driving shaft) 128, guard block 130, pawl support unit 132 and front end service portion 134.

Pawl support unit 132 is cylindric, has a pair of arm 132a, 132b, 132c, 132d respectively at its leading section and base end part.Arm 132a, the 132b that will be positioned at the leading section side are called the first arm, and arm 132c, the 132d that will be positioned at the base end part side are called second arm.Base end part at the second arm 132c, 132d is formed with protuberance 132e, 132f.Shown in Figure 10 B, these protuberances 132e, 132f have interior protuberance 132g, 132h side-prominent in the second arm 132c, the 132d of pawl support unit 132 and outwards outstanding outer protuberance 132i, 132j respectively.Interior protuberance 132g, 132h are combined in aftermentioned slotted hole (first notch) 128a of driving tube 128.And outer protuberance 132i, 132j are combined on the occlusal crib 118a (with reference to Fig. 8) of leading section of elongated tubular 118 of casing assembly 24.

Claw assembly is cylindric with link 126.Base end part at this link 126 has formed a pair of occlusal crib 126a.These occlusal cribs 126a has: the part of stretching with the rear end forward end skew back of link 126 from claw assembly; And from the anterior end of this part to the part of extending with the axial vertical direction of link 126.On these occlusal cribs 126a, the driving connecting pin 80a (with reference to Fig. 5) of the driving tube link 80 of above-mentioned Handleset 22 can carry out combination/disengagement respectively.Formed a pair of slotted hole 126b along this link 126 axial at claw assembly near with the base end part of link 126.On these slotted holes 126b, interior protuberance 114e, the 114f (with reference to Fig. 8) of fixed arm 114a, the 114b of the link 114 of casing assembly 24 can carry out combination/disengagement.

The outer peripheral face of the base end part of driving tube 128 is by being fixed on the inner peripheral surface of claw assembly with the leading section of link 126 as means such as bonding or welding.The leading section of driving tube 128 can dispose along its length slidably in the inboard of pawl support unit 132.Near the leading section of this driving tube 128, formed a pair of slotted hole 128a along driving tube 128 axial.As mentioned above, interior protuberance 132g, the 132h of the second arm 132c, the 132d of pawl support unit 132 embed in these slotted holes 128a from the outside.Therefore, driving tube 128 can be fixed on direction of rotation still along long endwisely slipping with respect to the pawl support unit.

Shown in Figure 10 A,, slightly near near the leading section, formed interior protuberance 128b outstanding in the radius vector than slotted hole 128a at the inner peripheral surface of driving tube 128.The outer peripheral face of tubular guard block (cartridge) 130 is for example on the inner peripheral surface of the leading section by being adhesively fixed on driving tube 128.Outer peripheral face at this guard block 130 has formed endless groove (slot part) 130a.The interior protuberance 128b of driving tube 128 is combined on this endless groove 130a.

Form pin at the leading section of driving tube 128 and born the 128c of portion.This pin bears the 128c of portion and is distolateral forward integratedly extension from the front edge and the driving tube 128 of driving tube 128.That is, this pin part of bearing the 128c of portion is wing from the front edge portion of driving tube 128 and stretches out.The leading section that this pin bears the 128c of portion is processed into circular-arc to the radially inner side of driving tube 128.Therefore, when connecting pin 142 described later was provided in this pin and holds on the 128c of portion, this connecting pin 142 was configured on the pawl main body 136, thereby driving tube 128 is connected with pawl main body 136.

As shown in Figure 9, front end service portion 134 possesses the hold assembly 138 that base end part roughly is arcual pawl main body 136 and clamping object (bio-tissue).Pawl main body 136 possesses a pair of arm 136a, 136b, and this a pair of arm 136a, 136b are connection status at leading section, are two at the base end part bifurcated.Therefore, the base end part in pawl main body 136 has formed predetermined gap.Hold assembly 138 be with as PTFE etc. have thermostability simultaneously to the lower material formation of the frictional resistance of its parts that will contact.On this hold assembly 138, a plurality of anti-slop serrations are arranged side by side in clamping face one side, thereby have formed the 138a of anti-slop serrations portion (clamping face) of indentation, and above-mentioned clamping face 138a carries out clamping to the bio-tissue as the object that solidifies or cut.The clamping of clamping face 138a by this hold assembly 138 and can prevent bio-tissue slip as the object that solidifies or cuts.Organism has formed lobe 138b on the opposition side of the clamping face 138a of this hold assembly 138, this lobe 138b is embedded between a pair of arm 136a, the 136b of pawl main body 136.Therefore, shown in Figure 11 B and Figure 11 C, hold assembly 138 is embedded in respect to pawl main body 136 in the gap of pawl main body 136, for example utilizes mode such as bonding to install.

As shown in Figure 9, the base end part at each arm 136a, 136b of pawl main body 136 has formed foot section 136c, 136d.Foot section 136c, the 136d of the base end part of the first arm 132a, the 132b of pawl master support unit 132 and arm 136a, the 136b of pawl main body 136 utilizes axle backing pin 140a, 140b to be connected.That is, pawl main body 136 utilizes axle backing pin 140a, 140b to be connected on the pawl support unit 132, and therefore, pawl main body 136 can be rotated with respect to the leading section of pawl support unit 132.

At the base end part of each arm 136a, 136b of pawl main body 136, formed pin hole in the upper edge side of foot section 136c, 136d, this pin hole bears the 128c of portion by connecting pin 142 with the pin of the leading section of driving tube 128 and is connected.Therefore, the pin of the leading section of driving tube 128 base end part that bears arm 136a, the 136b of 128c of portion and pawl main body 136 is connected by connecting pin 142.Thereby, when make driving tube 128 along claw assembly 26 axially make advance and retreat with respect to pawl support unit 132 time, then to be fulcrum with axle backing pin 140a, 140b rotate with respect to the leading section of pawl support unit 132 front end service portion 134.

At this, advance towards front by making driving tube 128, front end service portion 134 is closed.When the shutoff operation of this front end service portion 134, the hold assembly 138 of front end service portion 134 is pushed down the handling part 46 of the vibration transmission member 40 of probe 14.So, between the hold assembly 138 of handling part 46 and front end service portion 134, clamp object (bio-tissue).Front end service portion 134 also can use when peeling off bio-tissue.

If even the leading section pin of the most weak driving tube 128 of intensity holds the 128c of portion local damage, then pawl support unit 132 and driving tube 128 are fixed to prevent the state that rotates mutually by the engagement of slotted hole 128a and interior protuberance 132g, 132h.Therefore, during assembling, with respect to casing assembly 24, pawl holding components 132 also in case the moving state of spline be fixed.So, can prevent that the combination of the occlusal crib 118a of outer protuberance 132i, the 132j of claw stop holding components 132 and casing assembly 24 comes off.

So, constituted claw assembly 26 (with reference to Fig. 2 A).

Yet shown in Figure 11 A, the rear end face of the base end part of arm 136a, the 136b of pawl main body 136 is arch shape as mentioned above.Therefore, the intensity of the base end part of arm 136a, 136b and its leg 136c, 136d is then wanted the height of ratio such as rectangle or U-shaped if make comparisons in the situation of same thickness.Like this, the base end part of arm 136a, 136b can form with its leg 136c, 136d can keep identical intensity, again can be thinner than the wall of rectangle or U-shaped.Therefore, the rear end face of the base end part of pawl main body 136 also can kept under the same intensity little than rectangle or U.So, because the rear end of the base end part of pawl main body 136 is less, pawl main body 136 integral body can diminish.

On the outer peripheral face of arm 136a, the 136b of pawl main body 136, at the anterior position formation lobe 136e of leg 136c, 136d.The wall of these lobe 136e is thicker than the wall of leg 136c, 136b.As Figure 11 B and Figure 11 C, on arm 132a, the 132b of the leading section of pawl holding components 132, formed the protuberance 132k that contacts with the lobe 136e of pawl main body 136.Therefore, for example shown in Figure 11 C, even under lobe 136e and situation that protuberance 132k contacts, the thicker lobe 136e of wall that can enough pawl main bodys 136 bears the protuberance 132k of pawl holding components 132.Therefore, between the handling part 46 of hold assembly 138 and probe 14, do not press from both sides under the state of anything,, can prevent from handling part 46 grades are applied bigger power yet even close pawl main body 136.That is to say, limited by the stress of ultrasonic vibration biography, thereby can postpone the fatigue damage of probe 14 to handling part 46.

Below, the effect of the processor for ultrasonic wave 10 of this form of implementation is described.

As shown in Figure 2, processor for ultrasonic wave 10 disassembled one-tenth main unit assemblies 12, probe 14 and vibrator component 16.Main unit assembly 12 can be divided into Handleset 22, claw assembly 26 and casing assembly 24 again.

In assembling during processor for ultrasonic wave 10, after earlier casing assembly shown in Figure 12 24 and claw assembly 26 being fitted together, be assembled into insertion section unit block 28.

Shown in the arrow α among Figure 13 A, claw assembly 26 is inserted in base end part from the front end of casing assembly 24.Until claw assembly 26 is inserted into the position that to insert again with respect to casing assembly 24, outer protuberance 132i, the 132j (with reference to Figure 10 B) of the second arm 132c, 132d of the pawl holding components 132 of claw assembly 26 is coupled on the edge of opening of occlusal crib 118a (with reference to Fig. 8) of elongated tubular 118 of casing assembly 24 here.Like this, pawl main body 26 is located with respect to casing assembly 24.

Under this state, continue claw assembly 26 is inserted in the casing assembly 24.The claw assembly of the base end part of claw assembly 26 touches the casing assembly of base end part of casing assembly 24 with interior protuberance 114e, the 114f (with reference to Fig. 8) of fixed arm 114a, the 114b of the base end part of link 114 with the back edge of link 126.Because interior protuberance 114e, 114f are formed on the base end part of a pair of fixed arm 114a, 114b, so be accompanied by fixed arm 114a, the 114b into expansion of binding parts 126 of defeating with regulation, interior protuberance 114e, 114f also open.That is, interior protuberance 114e, 114f open towards isolating direction mutually because of the strain of fixed arm 114a, 114b.

On the other hand, outer protuberance 132i, the 132j of the pawl holding components 132 of claw assembly 26 is inserted into till the base end part position contacting with the occlusal crib 118a of the elongated tubular 118 of casing assembly 24 always, at this moment, the front end for arm 132c, the 132d of stage portion of the pawl holding components 132 of claw assembly 26 touches on the front end face of preceding end shield 120 of casing assembly 24.

Shown in the arrow β among Figure 13 B, with the clamping face (flank of tooth) of hold assembly 138 under the state of side at the moment, the clamping face 138a that makes claw assembly 26 rotates with respect to casing assembly 24 from side at the moment.That is to say, make casing assembly 24 corresponding to relatively inwards (clockwise) rotation of claw assembly 26.In other words, make claw assembly 26 corresponding to casing assembly court's side (counterclockwise) rotation at the moment relatively.

So, after outer protuberance 132i, the 132j of the pawl holding components 132 of claw assembly 26 rotates about 60 °, touch on the most inboard position of L shaped occlusal crib 118a of casing assembly 24 and carry out combination.

At this moment, protuberance 114e, 114f are fitted in a pair of slotted hole 126b of link 126 of base end part of claw assembly 26 (with reference to Fig. 5 and Fig. 6 A) from the outside respectively in a couple of fixed arm 114a, the 114b of casing assembly 24.That is the resilient-elasticity recovery original state of fixed arm 114a, 114b.

Thereby claw assembly 26 is assembled on two positions with respect to casing assembly 24, the insertion section unit block 28 shown in the pie graph 13C.Under this state, make the situation that claw assembly 26 rotates in the counterclockwise direction with respect to casing assembly 24 except utilizing power more than or equal to regulation, can prevent that claw assembly 26 from coming off out from casing assembly 24.

Then, casing assembly 24 and claw assembly 26 incorporate insertion section unit blocks 28 will be assembled on the Handleset 22.In the case, shown in Figure 14 A arrow γ, the leading section of shell link 72 of leading section that passes Handleset 22 is inboard and insertion section unit block 28 is inserted into the inside of Handleset 22.

Make fixed part (outer process portion) 114c, the 114d of link 114 of the base end part of casing assembly 24 as one man insert notch (expanded bore) 72a, the 72b of the shell link 72 shown in Fig. 6 A of Handleset 22.Therefore, just insertion section unit block 28 is located with respect to Handleset 22.

At the notch 72a of the shell link 72 of fixed part 114c, the 114d of the link 114 of casing assembly 24 and Handleset 22, when 72b is inconsistent, just casing assembly 24 successfully can not be inserted in the Handleset 22.

In the assembling process of above-mentioned insertion section unit block 28, claw assembly 26 to be inserted behind contact casing assembly 24, the situation that exists claw assembly 26 opposite shell assemblies 24 not rotate perhaps, is rotated incomplete situation.At this moment, interior protuberance 114e, the 114f of fixed arm 114a, the 114b of the rear end of casing assembly 24 just can not be chimeric with the slotted hole 126b on the link 126 of the base end part of claw assembly 26, and fixed arm 114a, 114b will keep to the open state of the direction that is separated from each other.Thereby.The external diameter of fixed part 114c, 114d is bigger than notch 72a, the 72b (with reference to Fig. 6 A) of shell link 72 inside, thereby just can not insert.

The casing assembly of the insertion section unit block 28 of being had good positioning by Handleset 22 touches the leading section of rotational fixation parts 68 with fixed part 114c, the 114b of link 114.Under this state, further insertion section unit block 28 is inserted in the Handleset 22.Make base end part one side shifting of the elastic force of rotational fixation parts 68 opposing helical springs 78, the base end part of rotational fixation parts 68 is touched on the outer peripheral face of driving tube link 80 towards operating portion main body 54.

So the driving tube connecting pin 80a of the leading section of driving tube link 80 is configured in the open rearward end portion of occlusal crib 126a of link 126 of the base end part of claw assembly 26.On the other hand, casing assembly can rotate around the axis with notch 72a, 72b with fixed part 114c, the 114d rotation direction location in the base end part side withdraws from shell link 72 of link 114.

Shown in arrow δ among Figure 14 B, at the clamping face 138a that makes front end service portion 134 under the state of side at the moment, the clamping face 138a that makes insertion section unit block 28 relative to Handleset 22 from rotating under the side direction at the moment, that is, make Handleset 22 with respect to inwards (clockwise direction) rotation of insertion section unit block 28.In other words, make insertion section unit block 28 with respect to side (counterclockwise) rotation at the moment of functional unit 22 courts.

So, as shown in Figure 6A, when the position of rotational fixation parts 68 on notch 68a, the 68b of fixed arm 114a, 114b and the leading section of rotational fixation parts 68 sway direction is consistent, just given potential energy towards front by helical spring 78.These rotational fixation parts 68 turn back to the position of the first pin 70a and the front end side contact of the notch 66c that rotates succeeding component 66.Notch 68a, the 68b of rotational fixation parts 68 and casing assembly are meshed with fixed part 114c, the 114d of fixed arm 114a, the 114b of link 114.Therefore, casing assembly 24 can not be fixed under the state that the axle that rotates fixed part 68 rotates.As shown in Figure 5, meanwhile, the effect of driving tube connecting pin 80a by the base end part occlusal crib 126a of the link 126 of claw assembly 26 is introduced into and is inserted into inboard position, thereby carries out axial restraint.

In addition, because casing assembly with notch 72a, the 72b of fixed part (outer process portion) 114a, the 114d of fixed arm 114a, the 114b of link 114 and shell link 72 along swaying direction staggered positions (with reference to Fig. 6 A), so casing assembly 24 relative Handlesets 22 are fixed on (length direction) in the axial direction.Casing assembly limits the distortion in its outer circumferentially diametric(al) outside by the hole portion of shell link 72 inboards of Handleset 22 with fixed arm 114a, the 114b of link 114.Therefore, under the state that assembles insertion section unit block 28 and Handleset 22, claw assembly 26 is fixed on fully the state that can not rotate with respect to casing assembly 24.Thereby the combination of the occlusal crib 118a of outer protuberance 132i, the 132j of pawl holding components 132 and the elongated tubular 118 of casing assembly 24 can not thrown off, and pawl holding components 132 is fixed fully with respect to casing assembly 24 in the axial direction.Thus, insertion section unit block 28 is fixed to and can not makes the state that sways with respect to rotational fixation parts 68.Follow in this, utilize the first pin 70a, by rotating succeeding component 66 and the 3rd pin 70c, be fixed on the state that sways each other with driving tube link 80 of preventing.Thus, the driving tube connecting pin 80a of driving tube link 80 makes rotational fixation parts 68 side shifting to the back-end, as long as the state that insertion section unit block 28 and driving tube link 80 cannot be in rotatablely just can prevent to deviate from from Handleset 22.

Thereby insertion section unit block 28 is assembling on two positions with respect to Handleset 22, has constituted the main unit assembly 12 shown in Figure 14 C.

As shown in Figure 2, linking probe 14 and vibrator component 16.In the case, the assembling screw thread of the base end part of probe 14 is screwed in the screwed hole of probe department of assembly of tubaeform front end of vibrator component 16.

The probe 14 of this state base end part from Handleset 22 is inserted to the leading section of insertion section unit block 28.When inserting, parallel plane 48a, the 48b (with reference to Fig. 2 B) of the odd-shaped cross section shape portion 48 of probe 14 is positioned on the determined position of parallel plane 90a, 90b by the positioning element 90 of Handleset 22.For example, in the present embodiment, insert symmetrically though can be 180 on two positions, operator insert according to the direction that the shape of the front end service portion 134 of handling part 46 that makes probe 14 and claw assembly 26 is consistent.

After being inserted into the base end part of probe 14, just the assembly connecting portion 32 (with reference to Fig. 2 A) with vibrator component 16 is installed on the base end part of Handleset 22.So the vibrator component guide 96 that the assembly connecting portion 32 of vibrator component 16 is bonded to by Handleset 22 is subjected in portion's 98 formed oscillator connecting portions 99 with C type rim bearing.So the handling part 46 of probe 14 is given prominence to and is being faced toward on the position of front end service portion 134, thereby has assembled processor for ultrasonic wave 10 (with reference to Fig. 1).

Below, the action of the processor for ultrasonic wave 10 that assembles like this is described.

If the operator rotates turning knob 74, then rotate succeeding component 66 and follow its rotation by turning knob 74 and the fixed rotationally first pin 70a.Rotate if rotate succeeding component 66, the shell link 72, the fixed part 76 that then are fixed on the inner peripheral surface of the leading section that rotates succeeding component 66 also rotate.

The driving tube link 80 that is connected with the 3rd pin 70c rotates, and the 3rd pin 70c combines with the notch 66c that rotates succeeding component 66.If driving tube link 80 rotates, then the slip bearing part 82 that connects with the second pin 70b rotates.If slip bearing part 82 rotates, then the positioning element 90 that connects with the 4th pin 70d rotates.Following several parts also rotate, and use the rotational fixation parts 68 that connected by the first pin 70a that is:; The casing assembly that is combined in the casing assembly 24 on notch 68a, the 68b of these rotational fixation parts 68 is with link 114; And be combined in this casing assembly with the claw assembly of the claw assembly 26 of interior protuberance 114e, the 114f of link 114 with link 126.With the fixedly also and then rotation of other parts of all-in-one-piece of these parts.Promptly, when the operator rotated turning knob 74, rotational fixation parts 68, rotation succeeding component 66, shell link 72, driving tube link 80, slip bearing part 82, positioning element 90, contact pipe 92 and vibrator component guide 96 all relatively rotated operating portion main body 54.Therefore, when turning knob 74 was rotated, casing assembly 24 and claw assembly 26 were also being followed turning knob 74 and are being rotated together.

Below, but the operator controls the 56a of finger hole separately, the 58a of fixed handle 56 and fixed handle 58, but fixed handle 58 is rotated with respect to fixed handle 56.But make the finger hole 58a of the finger hole 58a of fixed handle 58 near fixed handle 56.That is, but relatively closed fixed handle 56 and fixed handle 58.

But fixed handle 58 is that fulcrum rotates with the fulcrum pin 60 of operating portion main body 54.But along with the action of fixed handle 58, effect pin 62 is that fulcrum moves along camber line with fulcrum pin 60.The end of effect pin 62 is bonded to slide block 86 in the inside of operating portion main body 54 pin bears in the 86a of portion.Therefore, slide block 86 is pushed to the axial forward end side, but then the force transformation of closure fixed handle 58 becomes power towards the axial forward end side.On the contrary, but when the operation of opening fixed handle 58, slide block 86 is pushed to axial rearward end, but then opens the power of the force transformation one-tenth of fixed handle 58 towards axial rearward end.

Slide block 86 is driven power restraining spring 88 and gives potential energy towards axial rearward end one side with certain elastic force on slide block bearing part 82.Therefore, but when produce by the closed procedure of handle 58 towards the power of axle front when these driving force restraining spring 88 setting power are following, slide block bearing part 82 and driving tube link 80 forward end integratedly slide.But and when produce by the closed procedure of fixed handle 58 towards the power of axle front when the setting power of this driving force restraining spring 88 is above, slide block 86 opposing driving force restraining springs 88 with respect to slide block bearing part 82 and driving tube link 80 vertically front slide.Therefore, can prevent to surpass regulation towards the axial force transmission of axial forward end side to driving tube link 80.

But produce by the closed procedure of fixed handle 58 towards the power of axial forward end side when the setting power of driving force restraining spring 88 is following, as mentioned above, driving tube link 80 also slides to front end one side integratedly.Power towards the axial forward end side is delivered on the claw assembly usefulness link 126 that is positioned at claw assembly 26 rear end that combines with link 80 by driving tube connecting pin 80a.Pawl holding components 132 is by being fixed vertically with combining of casing assembly 24.Therefore, the driving tube 128 that is connected with link 126 with claw assembly with respect to pawl holding components 132 forward extreme direction slide.Driving tube 128 bears portion 128c place at the pin of leading section and is connected with pawl main body 136.Pawl main body 136 is being rotatably mounted by pawl holding components 132 and axle backing pin 140a, 140b.Therefore, pawl main body 136 is that fulcrum rotates (with reference to Figure 11 C) towards downside with axle backing pin 140a, 140b.

Thereby, bio-tissue is clipped between the handling part 46 of the clamping face 138a of hold assembly 138 of front end service portion 134 and probe 14, but, just can clamps bio-tissue by closure fixed handle 58.On the contrary, but when making fixed handle 58 open the direction operation with respect to fixed handle 56 courts, by with above-mentioned effect opposite effect, pawl main body 136 is that fulcrum rotates to upside with axle backing pin 140a, 140b, just can carry out the operation that pawl main body 136 and hold assembly 138 are opened.

If under the state of clamping bio-tissue, make the ultrasonic oscillator vibration of vibrator component 16, then the maximum gauge portion 44 from probe 14 passes through flare 42, vibration transmission member 40, and ultrasonic vibration is delivered on the handling part 46.Bio-tissue is subjected to carrying out with respect to the handling part 46 of probe 14 from the clamping face 138a of hold assembly 138 power of closed direction by pawl main body 136.Under this state,, then on the face of bio-tissue contact handling part 46, produce frictional heat, consolidation has taken place if transmit ultrasonic vibration.Further, the bio-tissue that becomes fragile because of consolidation is mechanically cut off by ultrasonic vibration.So, implemented to solidify and the processing of incision etc.

On the other hand, will provide the cable of high frequency electric to be connected to high frequency connecting pin 94 from high frequency electric source from scheming unshowned being used for, and from high frequency electric source supply high frequency electric current.So high frequency electric flows on the probe 14 through high frequency connecting pin 94, vibrator component guide 96, joint 92a contact pipe 92 and the positioning element 90 odd-shaped cross section shape portion 48 from probe 14.Therefore, high frequency electric is delivered to handling part 46 through odd-shaped cross section shape portion 48, flare 42, vibration transmission member 40.Thereby, if clamping the state of bio-tissue or handling part 46 is touched under the state of bio-tissue between the handling part 46 of the probe 14 of the clamping face 138a of the hold assembly 138 of front end service portion 134 and this clamping face 138a that standing facing each other, supply with electric current, then utilize Joule heat to carry out high frequency and handle by 46 pairs of bio-tissues of handling part.

In addition, just in case the most weak pin bears the 128c of portion fracture on the intensity of the driving tube 128 of claw assembly 26, slotted hole 128a combination because of interior protuberance 132g, 132h and the driving tube 128 of pawl holding components 132, and be fixed on rotation direction, so pawl holding components 132 is fixed under not rotatable state with respect to casing assembly 24 with link 126 by driving tube 128, claw assembly.Thereby the combination of the occlusal crib 118a of outer protuberance 132i, the 132j of pawl holding components 132 and elongated tubular 118 front ends of casing assembly 24 can not be disengaged, thereby can prevent that leading section from coming off out from pawl holding components 132.

After above-mentioned ultrasonic Treatment or high frequency processing end, need processor for ultrasonic wave 10 is decomposed in order to clean each assembly 14,16,22,24,26.At this moment, at first, pull down probe 14 and vibrator component 16 from Handleset 22 by the step opposite with above-mentioned effect.

As shown in the arrow ε among Figure 15 A, go out the turning knob (latch-release mechanism) 74 of Handleset 22 towards the base end part layback of operating portion main body 54.Because the rear end face of turning knob 74 touches the head of the first pin 70a, so rotational fixation parts 68 contract helical spring 78 on one side towards the flange part 66b side pressure of rotating succeeding component 66, Yi Bian make its base end part one side shifting to operating portion main body 54.At this moment, notch 68a, the 68b of the leading section of rotational fixation parts 68 (with reference to Fig. 6 A) and the combination of fixed arm 114a, 114b are disengaged.That is, rotational fixation parts 68 and casing assembly are disengaged with the combination of link 114, and insertion section unit block 28 just can rotate with respect to shell link 72.

Under this state, control the knob 112 of casing assembly 24, make insertion section unit block 28 towards assembling during processor for ultrasonic wave 10 counter-rotation of operation about 60, above-mentioned insertion section unit block 28 makes casing assembly 24 and claw assembly 26 integrated.That is, as rotating according to direction shown in the arrow ζ among Figure 15 A.So the position of fixed part (outer protuberance) 114c, the 114d of casing assembly usefulness link 114 and notch 72a, the 72b of shell link 72 is consistent.

Simultaneously, the driving tube connecting pin 80a of driving tube link 80 is configured in the peristome of claw assembly with the occlusal crib 126a of the rear end of link 126, and axial combination is thrown off.Under this state, shown in Figure 15 C arrow η, can take off insertion section unit block 28 from shell link 72.

Secondly, insertion section unit block 28 is resolved into casing assembly 24 and claw assembly 26.At this moment, implement opposite operation with package shell assembly 24 and claw assembly 26 operations.So insertion section unit block 28 can be broken down into casing assembly 24 and claw assembly 26.

Then, decompose probe 14 and vibrator component 16.Therefore, the operation of processor for ultrasonic wave 10 being resolved into five assemblies of probe 14, vibrator component 16, Handleset 22, casing assembly 24 and claw assembly 25 finishes at this point.

Under this state,, become reusable state to each assembly 14,16,22,24,26 cleaning/sterilization.When re-using, by above-mentioned steps assembling processor for ultrasonic wave 10.

As mentioned above, according to this form of implementation, can obtain following effect.

For example, though any part abrasion in the Handleset 22, casing assembly 24, claw assembly 26, when perhaps damaged, as long as change abrasion or damaged assembly, just can use as processor for ultrasonic wave 10 once more, therefore, can reduce the cost that causes because of replacing.

For main unit assembly 12, can pull down casing assembly 24 and claw assembly 26 from Handleset 22.Therefore, just need not special-purpose especially cleaning means, can clean reliably each assembly 22,24,26 at short notice.Thereby, can reduce and clean main unit assembly 12 needed costs.

In the use of processor for ultrasonic wave 10, for the driving tube 128 that has acted on claw assembly 26 more energetically, even the pin of the leading section that the intensity aspect is the most weak bears the 128c of portion breakage, but pawl holding components 132 is fixed to can not be with respect to the state of driving tube 128 rotations, therefore, can not be disengaged with the combining yet of occlusal crib 118a of elongated tubular 118 leading sections of casing assembly 24, can prevent that leading section from coming off from pawl holding components 132.

In this embodiment,, again insertion section unit block 28 is installed on the Handleset 22, thereby the effect of forming main unit assembly 12 is illustrated for after constituting insertion section unit block 28.In addition, also can followingly constitute, for example, casing assembly 24 is installed to Handleset 22 after, again claw assembly 26 is installed on casing assembly 24 and the Handleset 22, and forms assembling main unit assembly 12.

Main unit assembly 12 is being resolved under the situation of 3 assemblies 22,24,26, for decompose from Handleset 22 insert unit blocks 28 after, will insert the effect that unit block 28 resolves into two assemblies 24,26 again and be illustrated.In addition, also can followingly constitute, for example, after Handleset 22 decomposes claw assembly 26, decompose casing assembly 24 from Handleset 22 again.

Below, with reference to Figure 16 A to Figure 18 B second embodiment is described.Present embodiment is the variation of first embodiment, and the parts identical with the parts that illustrate in first embodiment adopt identical symbol, omit its detailed description.

In the present embodiment, for example, do not use the handling part 46 (with reference to Fig. 2 A) of the flexure type of the probe 14 that in first embodiment, illustrates, but shown in Figure 16 A, use handling part 46A along the straight-line extension type.Under the variform situation of the handling part 46 of the front end of probe 14, if it is identical to be designed to resonant frequency, then the length of probe 14 has nothing in common with each other.In the time can using common casing assembly 24, must have the Handleset 22 that the rigging position of vibrator component of making 16 and Handleset 22 staggers.Therefore, as shown in figure 17, corresponding to employed probe 14, Handleset 22 and claw assembly 26 should have all kinds.Figure 17 illustrates a wherein example.

In one hurdle of the probe 14 among Figure 17,4 types handling part 46 and corresponding with various handling part 46 respectively odd-shaped cross section shape portion 48 have been exemplified.Handling part 46 is by being in proper order from top to bottom: linear type 46A; Leading section is odd-shaped deformation type linear type handling part 46B; Each other at flexure type handling part 46C, the 46D of different directions bending.Each hurdle upside is a vertical view, and downside is a side view.The odd-shaped cross section shape 48A of portion of linear type handling part 46A is with shown in Figure 16 identical.Though this place does not illustrate, what the odd-shaped cross section shape 48A of portion of linear type handling part 46A also can be with shown in Fig. 2 B is identical.The odd-shaped cross section shape 48B of portion of deformation type linear type, flexure type handling part 46B, 46C, 46D possesses 3 planar portions 48f, 48g described later, 48h and a curved face part.

In claw assembly 26 1 hurdles, 3 types have been exemplified.Go up most the claw assembly 26A that the hurdle illustrates linear type front end service portion 134A and has this front end service portion 134A.The handling part 46 that above-mentioned linear type front end service portion 134A is fit to probe 14 is probe 14A, the 14B of linear type handling part 46A and deformation type linear type handling part 46B.Middle column and following hurdle have exemplified flexure type front end service portion 134B, 134C and have had such front end service portion 134B, claw assembly 26B, the 26C of 134C, and the handling part 46 that above-mentioned flexure type front end service portion 134B, 134C are fit to the probe 14 shown in the left side among Figure 17 respectively is probe 14C, the 14D of flexure type handling part 46B, 46C.The epimere on each hurdle is the vertical view of front end service portion 134, and the stage casing is the side view of front end service portion 134, and the below is the side view of claw assembly 26.

In Handleset 22 1 hurdles, 4 types have been exemplified.Make same type in appearance though go up Handleset 22A and several from top to bottom the 3rd Handleset 22C on hurdle most, for example positioning element 90 constitutes different with driving tube link 80 such inside.Similarly, though the 2nd Handleset 22B and to descend the Handleset 22D outward appearance on hurdle most be same type, inner constitute also different.These Handlesets 22B, 22D are the types that but fixed handle 58 is configured in upside among Figure 17 with respect to the central shaft of operating portion main body 54.

Have anti-error mounting mechanism on Handleset 22, this anti-error mounting mechanism prevents that the assembly of the mutual wrong combination in these classes from assembling up each other.Below, show anti-error mounting mechanism.

As mentioned above, probe 14 is at the shape difference of the handling part 46 of its front end, and when making that resonant frequency is consistent to be designed, its axial length has several millimeters difference.So in the handling part 46 of the probe 14 shown in Figure 17, linear type handling part 46A is different with the length of deformation type linear type handling part 46B.Flexure type handling part 46C, 46D are if flexibility is identical, and then length each other is just identical.Even linear type handling part 46A and deformation type linear type handling part 46B are compared with flexure type handling part 46C, 46D, length is also different.

For this length different multiple probe 14A, 14B, 14C, 14D,, will adjust the contact position of the length of front end service portion 134 of claw assembly 26 and Handleset 22 and vibrator component 16 in order can on a kind of casing assembly 24, to use.For example, for the probe 14 of the present embodiment of the handling part that possesses linear type handling part 46A and deformation type linear type handling part 46B, the front end service portion 134 of claw assembly 26 can use identical.

On the other hand because the length difference of probe 14, think and the claw assembly 26 and the casing assembly 24 of assembling equal length be necessary to change the contact position of vibrator component 16 for Handleset 22.For example, in the present embodiment, probe 14A must use any among Handleset 22A, the 22B, and probe 14B, 14C, 14D must use any among Handleset 22C, the 22D.Corresponding to the claw assembly 26 of the length of the probe 14 of band deformation type linear type handling part 46B, flexure type handling part 46C, 46D just separately front end service portion 134A of claw assembly 26A, 26B, 26C, the length difference of 134B, 134C.Therefore, the contact position (installation site) of Handleset 22C, 22D and vibrator component 16 is identical.So,, can use Handleset 22C, 22D with respect to claw assembly 26A, 26B, 26C.With respect to probe 14B, 14C, 14D, can use Handleset 22C, 22D.

Probe 14A shown in Figure 16 A possesses the cylindric handling part 46A of linear type shown in Figure 17.In the case, because handling part 46A is a drum completely, so, played the effect that can contact around any position of axle for the hold assembly 138 on the front end service portion 134 that is in claw assembly 26A.So, shown in Figure 16 B, design 3 planar portions 48c, 48d, 48e at circumference 3 equally divided positions on the outer peripheral face of the odd-shaped cross section shape 48A of portion.That is, planar portions 48c, 48d, 48e have been formed symmetrically with respect to the odd-shaped cross section shape 48A of portion.

Adorning on Handleset 22A, the 22B of probe 14A, though scheme not shownly, forming the positioning element (the 1st charging crane) of portion with holes, the shape of this hole portion is identical with this odd-shaped cross section shape 48A of portion.Therefore, probe 14A can install every 60 around axle with respect to the positioning element of Handleset 22A, 22B.

Handling part 46B, the 46C of probe 14B shown in Figure 17,14C, 14D, 46D must position to be integral the contacted mode in ground with each self-corresponding claw assembly 26A, the front end service portion 134A of 26B, 26C, 134B, 134C.Therefore, as shown in Figure 17, on the outer peripheral face of the odd-shaped cross section shape 48B of portion, planar portions 48f, 48g, 48h become 90 jiaos to be arranged on 3 positions.The plane that connects planar portions 48f, 48h can preferably form curved surface or a plurality of planes etc. outside a plane.

Adorning on Handleset 22C, the 22D of probe 14B, 14C, 14D, though scheme not shownly, forming the positioning element (the 1st charging crane) of portion with holes, the shape of this hole portion is identical with this odd-shaped cross section shape 48B of portion.Therefore, probe 14B, 14C, 14D can only install with respect to positioning element, slide block bearing part 82 and the driving tube link 80 of Handleset 22C, 22D with being integral.

In the present embodiment, shown in Figure 18 A and Figure 18 B, on the front end of the driving tube link 80 of Handleset 22A, 22B, 22C and 22D, only set a driving tube connecting pin (the 2nd charging crane) 80a.The claw assembly of claw assembly 26A, 26B, 26C only establish on link 126 one with this bonded occlusal crib 126a of driving tube connecting pin 80a.By means of such formation, assembled the insertion section unit block 28 of claw assembly 26 and casing assembly 24 with respect to 90 of the driving tube link 80 of Handleset 22, slide block bearing part 82 and positioning elements a local assembling location.

Therefore, in Figure 17, the odd-shaped cross section shape 48A of portion of probe 14A and the odd-shaped cross section shape 48B of portion of probe 14B, 14C, 14D have different shapes mutually.Therefore, probe 14A can not be installed on Handleset 22C, the 22D.Probe 14B, 14C, 14D can not be installed on Handleset 22A, the 22B.

Fully preventing under the mistake assembling situation of probe 14A, 14B, 14C, 14D and claw assembly 26A, 26B, 26C, for 22 of claw assembly 26A, 26B, 26C and each self-corresponding Handlesets in place assembling, and on each not mutual quantity and position more than two, make driving tube connecting pin 80a (with reference to Fig. 5 and Fig. 6) in the Handleset.On the other hand, the claw assembly of claw assembly 26A, 26B, 26C side is with also having set the quantity that combines with this driving tube connecting pin 80a and the occlusal crib 126a of location matches on the link 126.So claw assembly 26A, 26B, 26C and each self-corresponding Handleset 22 can only be installed at a place.

According to symbol used in literal used in the claim and the accompanying drawing content of the present utility model is done an explanation once more.
