Description
13~819~
The present invention relates to a surgical system, and more particularly, it relates to an excrement treating system which can effectively and safely be used or a patient who can not or almost not evacuate bowels by himself so as to crush the excrement in his rectum by mechanical vibration due to ultrasonic energy and can extract it outside his body~
Recently, since the man's span of life is prolonged more and more, the number of old folks who are always in the bed has been remarkably increased. For them, it is very important to successfully treat their excrements. Up to date, however, in order to solve such problem, although urine drawers have been proposed, other effective ~eans for treating the excrement have not yet been developed, and, therefore, normally, a diaper has still been used. When using the diaper, not only the patient who wears the diaper is subjected to considerable spiritual suffering, but also a person who nurses or attends to the diapered patient is also subjected to remarkable physical and mental suffering since he must frequently exchange the diapers.
Accordingly, the treatment of the excrement for the patient who is always in the bed is still now an important problem to be solved.
13~8~9'~
In order to treat the excrement, normally, a laxative, a clyster, an anal stimulus and the like have been used to promote the evacuation of the bowels or excrement according to the condition of constipation of the patient; on the other hand, as to the patient who can not or almost not evacuate the bowels by himself, a high pressure clyster, a removal of excrement, a suppository or the combination thereof has been used.
The "patient who can not or almost not evacuate the bowels by himself 1I means a person who cannot evacuate the bowels without help of other person.
For such a patient, the above-mentioned means (high pressure clyster and the like) have been adopted to;
but, such means have the following drawbacks:
(1) In the high pressure clyster, a catheter and a large-sized syringe are used so that a medical fluid is injected into the patient's rectum through his anus.
However, in this case, there was no practical exclusive instruments including the catheters used for such high pressure clyster. Further, when the medical fluid i5 injected into the rectum, there are problems that the air is introduced into the rectum together with the medical fluid and/or the medical fluid escapes outside the body, and that the wall of the rectum is damaged by an injector inserted ;nto the rectum. In addition, if the patient has hard feces, the high pressure clyster cannot demonstrate its ability effectively, with the result that the patient cannot fully evacuate the bowels ~31~
or it takes a long time for the patient to evacuate the bowels, whereby the patient will be considerable physical suffering.

In order to eliminate the above-mentioned conventional drawbacks, an improved excrement treating apparatus, as disclosed in the Japanese Patent Laid-Open No. 61-293472 and as described hereinbelow, has been proposed. That is to say, in this improved apparatus, which belongs to the high pressure clyster technique, a slidable guide pipe is arranged into an outer pipe to be inserted into the patient's rectum through his anus. In operation, at first, the guide pipe is extended into the patient's rectum beyond the outer pipe, and then the medical fluid is injected into the patient's rectum;
after the excxement is softened, the guide pipe is retracted and, at the same time, an free end of the outer pipe is opened, thereby extracting the softened excrement from the patient's rectum into an excrement reservoir tank through the opened end of the outer pipe by means of an appropriate vacuum pump~ This improved conventional apparatus aims to treat the excrement in a closed excrement treating ambience. However, since the patient's excrement is softened only by the medical fluid in this improved apparatus, this apparatus could not demonstrate its ability effectively for the patient who had hard feces.

DETP~ILED EXPLANATION OF THE PREFERRED EMBODIMENTS
~ he present invention will now be explained in connection with a preferred embodiment with referring to the accompanying drawings. Referring to Fig. 1, the excrement treating system mainly comprises an ultrasonic generation section, an irrigation section and a suction section.
~ 3 ~
1 First of all, the ultrasonic generation section will be explained. An insert 1 includes an transducer 3 of electrostrictive type or magnetostric-tive type incorporated therein, and a horn 2 constitut-ing an end of the insert 1, which i5 mechanic~lly vibrated or oscillated by ultrasonic energy. An oscillator 4 is an ultrasonic oscillator which can supply high frequency electric power of ultrasonic area to the transducer 3 through a cable 5 ~Fig. 3).
Next, the irrigation section will be explained. An irrigation pump 6 is of roller-type which is connected to the insert 1 and a cleaning liquid container 7 accommodating therein a cleaning liquid such as a clyster liquid, physiological salt solution and the like that is harmless to a living body and isotonic with the liquid in the living bodyO The irrigation pump 6 can inject the cleaning liquid from the container 7 into the rectum through the insert 1. A pre-heater 8 including a heater therein heats the cleaning liquid to be injected in the rectum up to an temperature near that of the rectum, for example, 35C - 42C~ The pre-heater 8 may be installed in any position between the insert 1 and the cleaning liquid container 7. It preferably is installed between the cleaning liquid container 7 and the irrigation pump 6 since the pre-heater 8 is not subjected to a liquid feeding pressure from the irrigation pump 6. Further, when the cleaning liquid container 7 is positioned in a higher position 1 than the insert 1 by a predetermined level, for example, by 50 cm - 100 cm, since the cleaning liquid is introduced into the rectum by potential energy thereof, the irrigation pump 6 can be omitted. An irrigation tube 9 for conveying the cleaning liquid may be made of appropriate elastic material such as soft vinyl chloride resin, silicone resin and the like. However, the irrigation tube 9 can be made of any other re~ins, if they are not deteriorated and decomposed by the cleaning liquid.
Next, the suction section will be explained.
A reservoir container 10 receives and stores the crushed excrement such as feces crushed by the horn 2 at the end of the insert 1, through a suction tube 11. The reservoir container 10 is arranged between the insert 1 and a suction pump 12~ and includes therein plastic container, a glass vase or bottle, or a disposable plastic bag therein. The container 10 can endure or resist the negative suction pressure of 0 mmHg - 760 mmHg derived from the suction pump 12. Further the suction tube 11 may be made of appropriate flexible material such as soft vinyl chloride resin, silicone resin and the like, which can endure the negative suction pressure derived from the suction pump 12.
In Fig. 2, the horn 2 is covered by an outer protector cover 13 to which an irrigation nipple 14 for introducing the cleaning liquid into the horn is attached by an appropriate means such as screws, ~318~9~
1 adhesive and the like. The irrigation tube 9 shown in Fig. 1 is conn~cted to the irrigation nipple 14.
suction nipple 17 extends through a lid 16 attached to the rear end of an insert body 15, and is connected to the transducer 3 incorporated in the body 15a The suction nipple 17 is also connected to the suction tube 11 (FigO 1) to remove the excrement crushed by the ultrasonic mechanical vibration by means of the horn 2.
In addition, the cable 5 passes through the lid 16 and is connected to the transducer 3 in the insert 1 to supply the high-frequency electric power to the transducer. The cable 5 is also connected to the oscillator 4 shown in Fig. 1.
The protector cover 13 is provided for preventing the horn 2 which is vibrated by the ultra-sonic energy from contacting the anus or the wall of the rectum, and may be made of any material ~uch as metal, plastics, rubber or the like. However, preferably, it is made of plastics, synthetic rubber, natuxal rubber or combination thereof so that it is smoothly inserted in the anus and that the patient does not feel cold when the insert 1 is inserted in the rectum. And, if neces-sary, when the insert 1 is inserted into the rectum, a lubricant such as jelly may be applied around the protector cover 13. A length of a straight portion 27 of the protector cover 13 is selected enough to crush the excrement from the anus to the rectum, and thus, is normally about 5 cm - 12 cm, and is, preferably, 10 cm.
~3181 ~
1 O-ring 18 is arranged on an inner peripheral surface of the protector cover 13 in one or more positions rearwardly of the irri~ation nipple 14 ~i.e., at the side where the transducer 3 is positioned) to prevent that the cleaning liquid flows into the transducer 3 through an annular passage formed between the horn 2 and the protector cover 13. The protector cover 13 is connected to the insert body 15 by an appropriate means such as an adhesive, screw connection, fit connection and the like. However, in consideration of the replacement of the horn, the screw connection or fit connection is desirable.
The insert body 15 incorporating the trans-ducer 3 therein is desirably made of material which is non-corrosive against the medical liquid, is light in weight and has a higher mechanical strength, euch as aluminum alloy, polysulfone resin, polyether sulfone resin, polyimide resin and the like. Preferably, poly-sulfone resin is used. O-ring 19 is arranged on an inner peripheral surface of the insert body 15 in one or more positions forwardly of a fixing plate 20 of the transducer 3 ~i.e~, at the side where the horn 2 is positioned~ to hold the transducer 3. The lid 16 may be made of the same material as that of the insert body 15.
However, as stated above, since the lid 16 is provided with openings for passing through the suction nipple 17 and the cable 5, it is feared that the water such as the cleaning liquid enters into the insert body 15 through ~ 3~81 ~
1 the clearances between the openings and the suction nipple 17 and/or cable 5. Accordingly/ to prevent the penetration of the water, such clearances must be sealed by an adhesive and the like. Thus, the lid 16 is pre-ferably made of polysulfone resin and the like which hasgood adhesion.
Since the irrigation nipple 14 and the suction nipple 17 are frequently connected to and disconnected from the irrigation tube 9 and the suction tube 11, these nipples may be made of material which has good strength and is non-corrosive, such as stainless steel group metal, polysulfone resin and the like.
Fig. 3 shows an example of an ultrasonic vibration portion (incorporated into the insert 1) constituted by the electrostrictive type transducer. A
front plate 21 made of duralumin or titanium alloy is arranged forwardly of the transducer 3 made of PZT
(plumbeous zirconate titanate) (i.e., at the side where the horn 2 is positioned) and a backing plate 22 made of duralumin or titanium alloy is arranged rearwardly of the transducer 3 (i.e., at the side where the suction nipple 27 is positioned), so that the unit is constitut-ed as a so-called bolt fastening langevin transducer (BLT) where the transducer is fastened by bolts (not shown) through the front and backing plates 21 and 22.
The fixing plate 2G having an outer diameter larger than that of the front plate 21 is provided on an end surface of the front plate 21 facing the transducer 3, i. 3 ~
1 whereby the transducer unit is fixed within the insert body 15 through a flange portion of the fixing plate 20 by means of an adhesive, screws and the like.
A tubular vibrator nipple 23 is provided at the rear end of the backing plate 22. The nipple 23 is connected to the suction nipple 17 by means of a connec-tion tube 24 made of material having good flexibility and heat resistance, such as fluororubber, silicone rubber and the like. The horn 2 rnay be made of non-corrosive metal having good tension resistance feature,such as duralumin or titanium alloy and the like. Pre-ferably, the horn 2 has a length substantially equal to integral multiple of 1/2 of wavelength of ultrasonics.
A suction passage 25 is provided to pass through the horn 2, front plate 21, transducer 3, backing plate 22, transducer nipple 23 and suction nipple 17. The trans-ducer 3 has a plurality of electrodes 26 to which the high-frequency electric power generated by the oscil-lator 4 is supplied through the cable S, thereby creat-ing axial ultrasonic vibration in the transducer 3,which ultrasonic vibration is transmitted to the horn 2.
Next, an operation for crushing the excrement in the rectum and extracting it by the suction force outside the body will be explained with reference to Figs. 1 to 3. At first, the straight portion 27 of the protector cover 13 of the insert 1 is inserted into the rectum through the anus by a proper extent, and then the cleaning liquid such as the physiological salt solution 1318~
1 i5 introduced into the rectum through the irrigation nipple 14, and at the same time, the tip of the horn 2 contacted to the excrement is subjected to the axial ultrasonic vibration by supplying the high-frequency electric power from the oscillator 4 to the transducer 3, thereby initiating the crushing operation for the excrement. The excrement with the cleaning liquid is emulsified with a cabitation phenomenon. The emulsified excrement is discharged into the reservoir container 10 through the suction passage 25 in the horn 2, suction nipple 17 and suction tube 11, by the action of the negative suction pressure generated by the SUCtiOII pump 12, and stored therein. As the excrement in the rectum is crushed and removed, the rectum contracts gradually;
thus, the excrement is always supplied to the tip of the horn 2 due to this contraction movement of the rectum, thereby crushing and removing all excrement in the rectum.
The frequency of the ultrasonics generated by the oscillator 4 is in the order of 17 kHz - 40 kHz, and preferably 18 - 23 kHz, in consideration of the fact that the straight portion 27 of the protector cover 13 inserted into the rectum through the anus can be lengthened and that amplitude of the vibration of the horn can be increased. Further, the electric power for generating the ultrasonics may be in the range of 100 W
- 1 XW, and preferably, is 200 W - 500 W. In order to effectively crush the excrement, the amplitude of the 1 3~19~
vibration of the horn 2 may be 40 ~m - 300 ~m, and preferably 100 ~Im - 200 ~m.
Next, other embodiments of the horn will be explained with reference to Figs. 4A to 11. In Figs. 4A
and 4B, a horn 28 has an irrigation feeding passage 29 and a suction passage 25 formed therein. The cleaning liquid is directly injected onto the excrement in the rectum from an irrigation nipple connecting port 30 formed in the rear end portion of the horn 28, through the passage 29 and the tip of the horn 28, whereas the excrement crushed by the ultrasonic vibration movement of the horn 28 is removed outside the rectum by the suction force, through the suction passage in the horn 28, a suction nipple connecting port 31 and the suction tube (not shown). The suction nipple connecting port 31 may be formed in a threaded portion 32 of the horn 28.
nith this construction, since the cleaning liquid can be introduced into the excrement directly from the tip of the horn 28 inserted into the excrement, the speed of the emulsion of the excrement i5 remarkably increased.
Figs. 5A to 8B show other embodiments of a working tip 53 of the horn 51. With these embodiment, a contacting area of the working tip 53 is increased to improve the working efficiency, and the jamming of the crushed excrement in the suction passage 54 are effec-tively prevented. In the embodiment shown in Figs. 5A, 5B, the suction passage 54 extends through the horn 51, and a shield wall 55 having a single hole or a plurality 131~
1 of small holes 56 is formed on the working tip 53 of the horn 51. The shield wall 55 has a thickness of 0.5 mm -25 mm, preerably 1 mm - 10 m. With such construction, the contacting area of the working tip 53 is increased S to improve the working efficiency considerably, and the jamming in the horn 51 is effectively prevented since the small holes 56 on the working tip i5 smaller than the suction passage 54. Figs. 6A, 6B show an example of the horn in which the suction passage 54 is opened to a rear side surface of the horn 51. This suction passage 54 is connected to a metal tube, plastic tube or the like arranged alon~ the side of ultra~onic operating instruments through the medium of a nipple and the like (not shown), and the crushed and emulsified excrement~is directed to the horn and then is discharged therefrom.
A configuration of the small hole or holes 56 is not lim~ted to a circular configuration, but may be an oval configuration, as shown in Figs. 7A, 7B.
Further, in place of the slngle or plural small holes, a star-shaped hole 57 as shown in Fig. 8A or a polygonal hole may be provided, by which the same technical effects as the previous ones can be obtained.
Further, Figs. 9 to 11 show the working tips of the horn~ In this case, it is devised that, when the horn is inserted into the rectum through the anus, the wall of the anus is not damaged by the horn. The tip 33 of the horn may be formed with an "R" or an oval arc as ~31~
1 shown in Fig. 9; or the tip 34 may be formed with a tapered configuration as shown in Fig. 10; or the tip 35 may be formed with the combination of the "R" and the taper, as shown in Fig. 11. With these construction, the horn can be easy to be inserted into the anus without damaging the same.
Incidentally, the horn 2, 28, 51 may be made of metal such as titanium alloy, aluminum alloy, or stainless steel, which is anti-corrosive and can re~ist the ultrasonic vibration of the order of 1000 m/see -6000 m/sec. In addition, carbon fiber reinforced metal obtained by mixing the metal such as aluminum and the carbon fibers, carbon fiber reinforced plastic obtained by mixing the plastic such as polysulfone and the carbon fibers, or graphite can be used to constitute the horn.
Next, Figs. 12A, 12B show anothex example of the positional relation between the horn and the protector cover~ In this example, the protector cover 36 is protruded from the horn 37 forwardly, thereby preventing the tip of the horn 37 being mechanically vibrated due to the ultrasonics from contacting with the wall of the rectum directly. In this case, the cleaning liquid is injected into the rectum from an end opening 39 of the protector cover 36 through an annular passage 38 formed between the horn 37 and the protector cover 36; on the other hand, the excrement crushed and emulsi-fied by the ultrasonic vibration of the tip sf the horn 37 is discharged through the suction passage 25 of the ~ 3 ~
1 horn 37 outside the body. The tip of the protector cover 36 with the opening 39 is formed with an "R" and in a tapexed configuration 40, as shown in Fig. 12A, so that the protector cover 36 can be easily inserted into the anus. Further, a distance between the end face of ~he protector cover 36 and that of the horn 37 may be selected to 0.5 mm - 10 mm, preferably 1 mm - 5 mm so that the cleaning liquid is prevented from being sucked directly into the suction pas~age 25.
Figs. 13A to 15~ show other protector covers.
In Figs. 13A, 13B, the protector cover 41 has a spiral groove 42 formed in an inner surface o~ the cover.
Further, the protector cover 43 may have axial ælits 44 formed in an inner surface of the cover as shown in Fig.
14B. Figs. 15A, 15B show a condition that the horn 37 is covered by the protector cover 41 of Fiy. 13A.
The number of the spiral grooves formed in the protector cover 41 is not limited, but may be two or three, in consideration of the fact that the grooves can be easily worked and that the cleaning liquid from the tip 45 of the cover can be effectively injected.
Further, the configurations and the number of the axial slits 44 of the protector cover 43 are also not limited, but, preferably, the plural slits are arranged in the start-shaped configuration in cross-section, as shown in Fig. 14B. The minimum inner diameter of the protector cover having such grooves 42 or slits 44 may be so selected that, as shown in Fig. 15A, the horn 37 is - 18 - .
~ 3 ~
1 inserted into the protector cover 41 or 43, the outer surface of straight portion 46 of the horn 37 is slidably engaged by the inner surface of the c~ver~ In this arrangementl the irrigation nipple (not shown) is attached to an irrigation nipple fixing threaded hole 47 or 48. Since the cleaning liquid supplied from the irrigation nipple flows through a space defined hy the horn 37 and the grooves 42 or slits 44 and is injected from the tip 45 or 49 toward the excrement, the horn 37 heated due to the mechanical vibration (by the ultra-sonics) of the horn itself can be effectively cooled, and the deviation of the protector cover 41 or 43 from the center of the horn 37 can also be prevented when the cover is inserted into the anus. It comes within the category of the present invention that above mentioned suction passage and annular passage of cleaning liquid can be used in the opposite way.
As mentioned above, according to the present invention, the excrement in the rectum can be crushed and emulsified and discharged effectively more than the conventional methods such as the clyster, removal of excrement, suppository or the like. Further, even the hard excrement or feces which was difficult to remove by the conventional methods can also be crushed easily for a short time. In addition, when tAe shield wall is provided on the tip of the horn, since the contacting area of the horn with the excrement, the crushing efficiency is still improved to reduce the treating 1 3 ~
1 time, and further, since the small hole or holes formed in the shield wall is smaller than the suction passage in the horn, the jamming of the crushed excrement in the horn is effectively prevented. Further, with the excrement treating system according to the present invention, the treating operating can be performed safely and comfortably without damaging the rectum and generating the bad smell and without suffering physically and mentally for the patient and/or the nurse. Accordingly the present invention provides an excellent industrial and medical excrement treating system.
In this way, the constipation cannot be relieved completely by the conventional excrement treating methods. Particularly, when the patient has hard feces, if the conventional excrement treating methods mentioned above are usedr not only the patient will be subjected to considerable physical and mental suffering, but also it is feared that the mucous membrane on the patient's rectum is damaged resulting in hemorrhage and/or contagion~ In addition, for the doctor or a person who treats the patient's excrement, ~3~
it takes a long time to carry out the excrement treating operation, and he suffers from the bad odor or smell derived from the patient's excrement.
In order to eliminate the above-mentioned conventional drawbacks, an improved excrement treating apparatus, as disclosed in the Japanese Patent Laid-Open No. 61-293472 and as described hereinbelow, has been proposed. That is to say, in this improved apparatus, which belongs to the high pressure clyster technique, a slidable guide pipe is arranged into an outer pipe to be inserted into the patient's rectum through his anus. In operation, at first, the guide pipe is extended into the patient's rectum beyond the outer pipe, and then the medical fluid is injected into the patient's rectum;
after the excxement is softened, the guide pipe is retracted and, at the same time, an free end of the outer pipe is opened, thereby extracting the softened excrement from the patient's rectum into an excrement reservoir tank through the opened end of the outer pipe by means of an appropriate vacuum pump~ This improved conventional apparatus aims to treat the excrement in a closed excrement treating ambience. However, since the patient's excrement is softened only by the medical fluid in this improved apparatus, this apparatus could not demonstrate its ability effectively for the patient who had hard feces.

DETP~ILED EXPLANATION OF THE PREFERRED EMBODIMENTS
~ he present invention will now be explained in connection with a preferred embodiment with referring to the accompanying drawings. Referring to Fig. 1, the excrement treating system mainly comprises an ultrasonic generation section, an irrigation section and a suction section.
~ 3 ~
1 First of all, the ultrasonic generation section will be explained. An insert 1 includes an transducer 3 of electrostrictive type or magnetostric-tive type incorporated therein, and a horn 2 constitut-ing an end of the insert 1, which i5 mechanic~lly vibrated or oscillated by ultrasonic energy. An oscillator 4 is an ultrasonic oscillator which can supply high frequency electric power of ultrasonic area to the transducer 3 through a cable 5 ~Fig. 3).
Next, the irrigation section will be explained. An irrigation pump 6 is of roller-type which is connected to the insert 1 and a cleaning liquid container 7 accommodating therein a cleaning liquid such as a clyster liquid, physiological salt solution and the like that is harmless to a living body and isotonic with the liquid in the living bodyO The irrigation pump 6 can inject the cleaning liquid from the container 7 into the rectum through the insert 1. A pre-heater 8 including a heater therein heats the cleaning liquid to be injected in the rectum up to an temperature near that of the rectum, for example, 35C - 42C~ The pre-heater 8 may be installed in any position between the insert 1 and the cleaning liquid container 7. It preferably is installed between the cleaning liquid container 7 and the irrigation pump 6 since the pre-heater 8 is not subjected to a liquid feeding pressure from the irrigation pump 6. Further, when the cleaning liquid container 7 is positioned in a higher position 1 than the insert 1 by a predetermined level, for example, by 50 cm - 100 cm, since the cleaning liquid is introduced into the rectum by potential energy thereof, the irrigation pump 6 can be omitted. An irrigation tube 9 for conveying the cleaning liquid may be made of appropriate elastic material such as soft vinyl chloride resin, silicone resin and the like. However, the irrigation tube 9 can be made of any other re~ins, if they are not deteriorated and decomposed by the cleaning liquid.
Next, the suction section will be explained.
A reservoir container 10 receives and stores the crushed excrement such as feces crushed by the horn 2 at the end of the insert 1, through a suction tube 11. The reservoir container 10 is arranged between the insert 1 and a suction pump 12~ and includes therein plastic container, a glass vase or bottle, or a disposable plastic bag therein. The container 10 can endure or resist the negative suction pressure of 0 mmHg - 760 mmHg derived from the suction pump 12. Further the suction tube 11 may be made of appropriate flexible material such as soft vinyl chloride resin, silicone resin and the like, which can endure the negative suction pressure derived from the suction pump 12.
In Fig. 2, the horn 2 is covered by an outer protector cover 13 to which an irrigation nipple 14 for introducing the cleaning liquid into the horn is attached by an appropriate means such as screws, ~318~9~
1 adhesive and the like. The irrigation tube 9 shown in Fig. 1 is conn~cted to the irrigation nipple 14.
suction nipple 17 extends through a lid 16 attached to the rear end of an insert body 15, and is connected to the transducer 3 incorporated in the body 15a The suction nipple 17 is also connected to the suction tube 11 (FigO 1) to remove the excrement crushed by the ultrasonic mechanical vibration by means of the horn 2.
In addition, the cable 5 passes through the lid 16 and is connected to the transducer 3 in the insert 1 to supply the high-frequency electric power to the transducer. The cable 5 is also connected to the oscillator 4 shown in Fig. 1.
The protector cover 13 is provided for preventing the horn 2 which is vibrated by the ultra-sonic energy from contacting the anus or the wall of the rectum, and may be made of any material ~uch as metal, plastics, rubber or the like. However, preferably, it is made of plastics, synthetic rubber, natuxal rubber or combination thereof so that it is smoothly inserted in the anus and that the patient does not feel cold when the insert 1 is inserted in the rectum. And, if neces-sary, when the insert 1 is inserted into the rectum, a lubricant such as jelly may be applied around the protector cover 13. A length of a straight portion 27 of the protector cover 13 is selected enough to crush the excrement from the anus to the rectum, and thus, is normally about 5 cm - 12 cm, and is, preferably, 10 cm.
~3181 ~
1 O-ring 18 is arranged on an inner peripheral surface of the protector cover 13 in one or more positions rearwardly of the irri~ation nipple 14 ~i.e., at the side where the transducer 3 is positioned) to prevent that the cleaning liquid flows into the transducer 3 through an annular passage formed between the horn 2 and the protector cover 13. The protector cover 13 is connected to the insert body 15 by an appropriate means such as an adhesive, screw connection, fit connection and the like. However, in consideration of the replacement of the horn, the screw connection or fit connection is desirable.
The insert body 15 incorporating the trans-ducer 3 therein is desirably made of material which is non-corrosive against the medical liquid, is light in weight and has a higher mechanical strength, euch as aluminum alloy, polysulfone resin, polyether sulfone resin, polyimide resin and the like. Preferably, poly-sulfone resin is used. O-ring 19 is arranged on an inner peripheral surface of the insert body 15 in one or more positions forwardly of a fixing plate 20 of the transducer 3 ~i.e~, at the side where the horn 2 is positioned~ to hold the transducer 3. The lid 16 may be made of the same material as that of the insert body 15.
However, as stated above, since the lid 16 is provided with openings for passing through the suction nipple 17 and the cable 5, it is feared that the water such as the cleaning liquid enters into the insert body 15 through ~ 3~81 ~
1 the clearances between the openings and the suction nipple 17 and/or cable 5. Accordingly/ to prevent the penetration of the water, such clearances must be sealed by an adhesive and the like. Thus, the lid 16 is pre-ferably made of polysulfone resin and the like which hasgood adhesion.
Since the irrigation nipple 14 and the suction nipple 17 are frequently connected to and disconnected from the irrigation tube 9 and the suction tube 11, these nipples may be made of material which has good strength and is non-corrosive, such as stainless steel group metal, polysulfone resin and the like.
Fig. 3 shows an example of an ultrasonic vibration portion (incorporated into the insert 1) constituted by the electrostrictive type transducer. A
front plate 21 made of duralumin or titanium alloy is arranged forwardly of the transducer 3 made of PZT
(plumbeous zirconate titanate) (i.e., at the side where the horn 2 is positioned) and a backing plate 22 made of duralumin or titanium alloy is arranged rearwardly of the transducer 3 (i.e., at the side where the suction nipple 27 is positioned), so that the unit is constitut-ed as a so-called bolt fastening langevin transducer (BLT) where the transducer is fastened by bolts (not shown) through the front and backing plates 21 and 22.
The fixing plate 2G having an outer diameter larger than that of the front plate 21 is provided on an end surface of the front plate 21 facing the transducer 3, i. 3 ~
1 whereby the transducer unit is fixed within the insert body 15 through a flange portion of the fixing plate 20 by means of an adhesive, screws and the like.
A tubular vibrator nipple 23 is provided at the rear end of the backing plate 22. The nipple 23 is connected to the suction nipple 17 by means of a connec-tion tube 24 made of material having good flexibility and heat resistance, such as fluororubber, silicone rubber and the like. The horn 2 rnay be made of non-corrosive metal having good tension resistance feature,such as duralumin or titanium alloy and the like. Pre-ferably, the horn 2 has a length substantially equal to integral multiple of 1/2 of wavelength of ultrasonics.
A suction passage 25 is provided to pass through the horn 2, front plate 21, transducer 3, backing plate 22, transducer nipple 23 and suction nipple 17. The trans-ducer 3 has a plurality of electrodes 26 to which the high-frequency electric power generated by the oscil-lator 4 is supplied through the cable S, thereby creat-ing axial ultrasonic vibration in the transducer 3,which ultrasonic vibration is transmitted to the horn 2.
Next, an operation for crushing the excrement in the rectum and extracting it by the suction force outside the body will be explained with reference to Figs. 1 to 3. At first, the straight portion 27 of the protector cover 13 of the insert 1 is inserted into the rectum through the anus by a proper extent, and then the cleaning liquid such as the physiological salt solution 1318~
1 i5 introduced into the rectum through the irrigation nipple 14, and at the same time, the tip of the horn 2 contacted to the excrement is subjected to the axial ultrasonic vibration by supplying the high-frequency electric power from the oscillator 4 to the transducer 3, thereby initiating the crushing operation for the excrement. The excrement with the cleaning liquid is emulsified with a cabitation phenomenon. The emulsified excrement is discharged into the reservoir container 10 through the suction passage 25 in the horn 2, suction nipple 17 and suction tube 11, by the action of the negative suction pressure generated by the SUCtiOII pump 12, and stored therein. As the excrement in the rectum is crushed and removed, the rectum contracts gradually;
thus, the excrement is always supplied to the tip of the horn 2 due to this contraction movement of the rectum, thereby crushing and removing all excrement in the rectum.
The frequency of the ultrasonics generated by the oscillator 4 is in the order of 17 kHz - 40 kHz, and preferably 18 - 23 kHz, in consideration of the fact that the straight portion 27 of the protector cover 13 inserted into the rectum through the anus can be lengthened and that amplitude of the vibration of the horn can be increased. Further, the electric power for generating the ultrasonics may be in the range of 100 W
- 1 XW, and preferably, is 200 W - 500 W. In order to effectively crush the excrement, the amplitude of the 1 3~19~
vibration of the horn 2 may be 40 ~m - 300 ~m, and preferably 100 ~Im - 200 ~m.
Next, other embodiments of the horn will be explained with reference to Figs. 4A to 11. In Figs. 4A
and 4B, a horn 28 has an irrigation feeding passage 29 and a suction passage 25 formed therein. The cleaning liquid is directly injected onto the excrement in the rectum from an irrigation nipple connecting port 30 formed in the rear end portion of the horn 28, through the passage 29 and the tip of the horn 28, whereas the excrement crushed by the ultrasonic vibration movement of the horn 28 is removed outside the rectum by the suction force, through the suction passage in the horn 28, a suction nipple connecting port 31 and the suction tube (not shown). The suction nipple connecting port 31 may be formed in a threaded portion 32 of the horn 28.
nith this construction, since the cleaning liquid can be introduced into the excrement directly from the tip of the horn 28 inserted into the excrement, the speed of the emulsion of the excrement i5 remarkably increased.
Figs. 5A to 8B show other embodiments of a working tip 53 of the horn 51. With these embodiment, a contacting area of the working tip 53 is increased to improve the working efficiency, and the jamming of the crushed excrement in the suction passage 54 are effec-tively prevented. In the embodiment shown in Figs. 5A, 5B, the suction passage 54 extends through the horn 51, and a shield wall 55 having a single hole or a plurality 131~
1 of small holes 56 is formed on the working tip 53 of the horn 51. The shield wall 55 has a thickness of 0.5 mm -25 mm, preerably 1 mm - 10 m. With such construction, the contacting area of the working tip 53 is increased S to improve the working efficiency considerably, and the jamming in the horn 51 is effectively prevented since the small holes 56 on the working tip i5 smaller than the suction passage 54. Figs. 6A, 6B show an example of the horn in which the suction passage 54 is opened to a rear side surface of the horn 51. This suction passage 54 is connected to a metal tube, plastic tube or the like arranged alon~ the side of ultra~onic operating instruments through the medium of a nipple and the like (not shown), and the crushed and emulsified excrement~is directed to the horn and then is discharged therefrom.
A configuration of the small hole or holes 56 is not lim~ted to a circular configuration, but may be an oval configuration, as shown in Figs. 7A, 7B.
Further, in place of the slngle or plural small holes, a star-shaped hole 57 as shown in Fig. 8A or a polygonal hole may be provided, by which the same technical effects as the previous ones can be obtained.
Further, Figs. 9 to 11 show the working tips of the horn~ In this case, it is devised that, when the horn is inserted into the rectum through the anus, the wall of the anus is not damaged by the horn. The tip 33 of the horn may be formed with an "R" or an oval arc as ~31~
1 shown in Fig. 9; or the tip 34 may be formed with a tapered configuration as shown in Fig. 10; or the tip 35 may be formed with the combination of the "R" and the taper, as shown in Fig. 11. With these construction, the horn can be easy to be inserted into the anus without damaging the same.
Incidentally, the horn 2, 28, 51 may be made of metal such as titanium alloy, aluminum alloy, or stainless steel, which is anti-corrosive and can re~ist the ultrasonic vibration of the order of 1000 m/see -6000 m/sec. In addition, carbon fiber reinforced metal obtained by mixing the metal such as aluminum and the carbon fibers, carbon fiber reinforced plastic obtained by mixing the plastic such as polysulfone and the carbon fibers, or graphite can be used to constitute the horn.
Next, Figs. 12A, 12B show anothex example of the positional relation between the horn and the protector cover~ In this example, the protector cover 36 is protruded from the horn 37 forwardly, thereby preventing the tip of the horn 37 being mechanically vibrated due to the ultrasonics from contacting with the wall of the rectum directly. In this case, the cleaning liquid is injected into the rectum from an end opening 39 of the protector cover 36 through an annular passage 38 formed between the horn 37 and the protector cover 36; on the other hand, the excrement crushed and emulsi-fied by the ultrasonic vibration of the tip sf the horn 37 is discharged through the suction passage 25 of the ~ 3 ~
1 horn 37 outside the body. The tip of the protector cover 36 with the opening 39 is formed with an "R" and in a tapexed configuration 40, as shown in Fig. 12A, so that the protector cover 36 can be easily inserted into the anus. Further, a distance between the end face of ~he protector cover 36 and that of the horn 37 may be selected to 0.5 mm - 10 mm, preferably 1 mm - 5 mm so that the cleaning liquid is prevented from being sucked directly into the suction pas~age 25.
Figs. 13A to 15~ show other protector covers.
In Figs. 13A, 13B, the protector cover 41 has a spiral groove 42 formed in an inner surface o~ the cover.
Further, the protector cover 43 may have axial ælits 44 formed in an inner surface of the cover as shown in Fig.
14B. Figs. 15A, 15B show a condition that the horn 37 is covered by the protector cover 41 of Fiy. 13A.
The number of the spiral grooves formed in the protector cover 41 is not limited, but may be two or three, in consideration of the fact that the grooves can be easily worked and that the cleaning liquid from the tip 45 of the cover can be effectively injected.
Further, the configurations and the number of the axial slits 44 of the protector cover 43 are also not limited, but, preferably, the plural slits are arranged in the start-shaped configuration in cross-section, as shown in Fig. 14B. The minimum inner diameter of the protector cover having such grooves 42 or slits 44 may be so selected that, as shown in Fig. 15A, the horn 37 is - 18 - .
~ 3 ~
1 inserted into the protector cover 41 or 43, the outer surface of straight portion 46 of the horn 37 is slidably engaged by the inner surface of the c~ver~ In this arrangementl the irrigation nipple (not shown) is attached to an irrigation nipple fixing threaded hole 47 or 48. Since the cleaning liquid supplied from the irrigation nipple flows through a space defined hy the horn 37 and the grooves 42 or slits 44 and is injected from the tip 45 or 49 toward the excrement, the horn 37 heated due to the mechanical vibration (by the ultra-sonics) of the horn itself can be effectively cooled, and the deviation of the protector cover 41 or 43 from the center of the horn 37 can also be prevented when the cover is inserted into the anus. It comes within the category of the present invention that above mentioned suction passage and annular passage of cleaning liquid can be used in the opposite way.
As mentioned above, according to the present invention, the excrement in the rectum can be crushed and emulsified and discharged effectively more than the conventional methods such as the clyster, removal of excrement, suppository or the like. Further, even the hard excrement or feces which was difficult to remove by the conventional methods can also be crushed easily for a short time. In addition, when tAe shield wall is provided on the tip of the horn, since the contacting area of the horn with the excrement, the crushing efficiency is still improved to reduce the treating 1 3 ~
1 time, and further, since the small hole or holes formed in the shield wall is smaller than the suction passage in the horn, the jamming of the crushed excrement in the horn is effectively prevented. Further, with the excrement treating system according to the present invention, the treating operating can be performed safely and comfortably without damaging the rectum and generating the bad smell and without suffering physically and mentally for the patient and/or the nurse. Accordingly the present invention provides an excellent industrial and medical excrement treating system.
