FIG. 1 toFIG. 5 . The treatment system is used for arthroscopic surgery performed for a target region such as a joint of a shoulder, knee, elbow, etc. Specifically, as shown inFIG. 1 , atreatment system 11 is used for treatment within a joint, namely, between afirst bone 12 and asecond bone 13. Thetreatment system 11 includes anarthroscopic apparatus 14, an ultrasonic treatment apparatus 15 (ultrasonic treatment assembly), and aperfusion apparatus 16. Anarthroscope 18 of thearthroscopic apparatus 14 is inserted into thejoint cavity 17 through afirst cannula 37 a, and asheath 51 and a probe 44 (described later) of theultrasonic treatment apparatus 15 are inserted into ajoint cavity 17 through asecond cannula 37 b. - The
arthroscopic apparatus 14 is provided with thearthroscope 18 which monitors an inside of a joint of a patient, namely, thejoint cavity 17, animage processing unit 26 that performs image processing based on a subject image captured by thearthroscope 18, and amonitor 22 that displays an image generated by the image processing at theimage processing unit 26. - The
arthroscope 18 includes aninsertion section 23 and aholding section 24. In a treatment using thearthroscope 18, a distal end portion of theinsertion section 23 is inserted into a joint. One end of auniversal cord 25 is connected to theholding section 24. The other end of theuniversal cord 25 is connected to theimage processing unit 26. Theimage processing unit 26 is electrically coupled to a monitor 22 (display unit). - An imaging element is provided at a distal end portion of the
insertion section 23. The imaging element is electrically connected to theimage processing unit 26. An image captured by the imaging element is subjected to image processing at theimage processing unit 26, and is displayed on themonitor 22. Thearthroscope 18 is coupled to a light source unit (not shown in the drawings), and light emitted from the light source unit is applied to a subject. - The
perfusion apparatus 16 includes an inflatableliquid source 27 in which perfusate such as a saline solution is shared, aperfusion pump unit 28, aliquid transfer tube 31, one end of which is connected to theliquid source 27, adrainage tube 32, and asuction bottle 33 connected to one end of thedrainage tube 32. Thesuction bottle 33 is connected to asuction pump unit 34 attached to a wall of an operation room. Theperfusion pump unit 28 is capable of transferring perfusate from theliquid source 27 by means of aliquid transfer pump 35. Theperfusion pump unit 28 is capable of switching suction and stopping suction of perfusate within thejoint cavity 17 relative to thesuction bottle 33 by opening or closing apinch valve 36 used as a drainage valve. - The
liquid transfer tube 31, which is a liquid transfer path, is connected to thefirst cannula 37 a at the other end. Theliquid transfer tube 32 is connected to thefirst cannula 37 a at the other end. Accordingly, it is possible to transfer perfusate into thejoint cavity 17 or drain perfusate from thejoint cavity 17 through thefirst cannula 37 a. It may be possible to provide a portal to a patient with which perfusate can be transferred or drained. - As shown in
FIGS. 1 and 2 , theultrasonic treatment apparatus 15 is provided with a handpiece (ultrasonic treatment apparatus) 41, anultrasonic vibrator unit 40 attached to thehandpiece 41, apower supply unit 42, acable 43 which connects theultrasonic vibrator unit 40 and thepower supply unit 42. In the following description, it is assumed that one of the directions in a longitudinal axis C of the probe 44 (main body section 61) provided to thehandpiece 41 is a distal end direction C1, and another direction which is opposite to the distal end direction C1 is a proximal end direction C2, as shown inFIG. 2 . - As shown in
FIG. 1 , thepower supply unit 42 is provided with anenergy controller 45, and an ultrasoniccurrent supply unit 46 which is controlled by theenergy controller 45 to supply power to a vibration generator. Theultrasonic vibrator unit 40 has avibration generator 48 which generates ultrasonic vibration, inside of avibrator case 40A. - As shown in.
FIGS. 1 to 3 , the handpiece (ultrasonic treatment apparatus) 41 is provided with ahousing 47 constituting an outer shell, the rod-like probe 44 connected to thevibration generator 48, the hollow (cylindrical)sheath 51 which covers the periphery of theprobe 44 to protect theprobe 44, and an energy input button 52 (switch) provided to thehousing 47. Theenergy input button 52 is not shown inFIGS. 2 and 3 . Theenergy input button 52 may be provided as a foot switch separated from thehandpiece 41. - The
vibrator case 40A (piezoelectric element 53) is connected to one end of acable 43. The other end of thecable 43 is connected to thepower supply unit 42. If a doctor operates theenergy input button 52, theenergy controller 45 senses an input operation of theenergy input button 52. Theenergy controller 45 then controls the ultrasoniccurrent supply unit 46 to supply power to thevibration generator 48. By this operation, ultrasonic vibration (ultrasonic energy) is transmitted to theprobe 44, and the ultrasonic vibration is transmitted through theprobe 44 to a bone (living tissue) which is a treatment target. Accordingly, excision or removal treatment, for example, can be applied to a bone (living tissue). - The
vibration generator 48 is provided with a plurality of piezoelectric elements (vibrators) 53 and ahorn member 54. The piezoelectric elements 53 generate ultrasonic vibration upon receipt of power supplied from thepower supply unit 42. Thehorn member 54 increases an amplitude of the ultrasonic vibration generated at the piezoelectric elements 53 and transmits the ultrasonic vibration to theprobe 44. The ultrasonic vibration in the direction along the longitudinal axis C (the direction in which theprobe 44 is shortened and extended) is, for example, transmitted to thehorn member 54 and theprobe 44 connected to thehorn member 54. Aresin sealing member 56 that prevents liquid from entering the inside of thesheath 51 is provided at a position corresponding to a node position 55 (a node position closest to the distal end direction C1 side) of the ultrasonic vibration traveling on theprobe 44 as stated above. The sealingmember 56 has a ring-like shape, and supports theprobe 44 so that theprobe 44 is positioned at the center of thesheath 51. - As shown in
FIGS. 2 to 4 , theprobe 44 is formed of a metallic material having biocompatibility (for example, a titanium alloy, etc.) as a rod-like shape. Theprobe 44 has amain body section 61 extending as a rod-like shape, and atreatment section 61A (distal end direction C1 side section) provided at the distal end direction C1 side of themain body section 61. Thetreatment section 61A is bent in a direction different from the direction along the longitudinal axis C. Thetreatment section 61A has a bendingportion 62 provided in a part close to the distal end direction C1 of themain body section 61, and an excision region 63 (claw portion) extending in a direction crossing the longitudinal axis C from the part closer to the distal end direction C1 side than the bendingportion 62, and excises a bone by transmission of ultrasonic vibration. Thetreatment section 61A has a diameter smaller than the other portions of theprobe 44, and is easier to be broken then the other portions. In particular, for removal of a hard tissue such as bone, an amplitude of ultrasonic vibration is set to be relatively large, and a stress applied to theprobe 44 is relatively large. Thetreatment section 61A receives a relatively large stress in the same manner. - The
main body section 61 is capable of transmitting ultrasonic vibration received from thevibration generator 48 from the proximal end to the distal end direction C1 side. Thetreatment section 61A is bent to protrude in the direction crossing the longitudinal axis C of themain body section 61. The bending portion 62 (top portion) has a largest curvature in themain body section 61 of theprobe 44. While ultrasonic vibration is applied during treatment, the bendingportion 62 is easily broken in a case of coming into contact with thearthroscope 18. - The wavelength of ultrasonic vibration to be input to the
probe 44 is determined based on a resonant frequency of the piezoelectric elements 53 of theultrasonic vibrator unit 40. That is, the length of theprobe 44 is determined based on the piezoelectric elements 53 to be used. Thus, theprobe 44 has a length so that an anti-node position of vibration is determined at thetreatment section 61A when ultrasonic vibration is input to the proximal end of theprobe 44 from the piezoelectric elements 53 of theultrasonic vibrator unit 40, and the ultrasonic vibration is transmitted to the distal end direction C1 side from the proximal end of theprobe 44. The anti-node position of vibration preferably matches the position of theexcision region 63. That is, the position of theexcision region 63 is adjusted to correspond to the anti-node position of vibration. When ultrasonic vibration is transmitted, a first node position of vibration at the proximal end side relative to the anti-node position of vibration is defined between the proximal end and the distal end of themain body section 61 of theprobe 44. - The
sheath 51 includes afirst portion 64 having a tubular shape such as a cylindrical shape, and asecond portion 65 extending from thefirst portion 64. Thesecond portion 65 is provided at a side where theexcision region 63 is provided. As shown inFIG. 4 , thesecond portion 65 is provided to project from thefirst portion 64 and to have substantially half of the size of the cylinder corresponding to 180° around the longitudinal axis C, for example. Thesecond portion 65 extends from thefirst portion 64 to the position to cover a portion corresponding to the bendingportion 62 of theprobe 44. The distal end of thesecond portion 65 extends in the distal end direction C1 over the bendingportion 62 in comparison with the distal end of thefirst portion 64. On the other hand, thesecond portion 65 is not provided to the side opposite at the side where theexcision region 63 is defined, and theprobe 44 is externally exposed at this position. Accordingly, the side opposite to the side corresponding to thesecond portion 65 of the proximal end portion of thetreatment section 61A of theprobe 44 is defined as an exposedportion 66. - Next, a surgical method using the
treatment system 11 according to the present embodiment will be described with reference toFIG. 5 . Theultrasonic treatment apparatus 15 of thetreatment system 11 according to the present embodiment is used within thejoint cavity 17, for example, and is capable of resecting and removing a tissue to be removed (removal target) by bringing theprobe 44 to which ultrasonic vibration is transmitted into contact with a removal target such as a bone spur. - First, the
joint cavity 17 is filled with perfusate by a well-known method. A suitable portal that reaches into thejoint cavity 17 from the outside is used to insert thearthroscope 18 into thejoint cavity 17 to check the state of a patient. A doctor uses another portal to insert theprobe 44 and thesheath 51 of thehandpiece 41 into thejoint cavity 17. A plurality of well-known portals which are access paths to the inside of a joint are present in each joint. - When inserting the
probe 44 into thejoint cavity 17, theprobe 44 to which ultrasonic vibration is transmitted can be used for removal of intervening soft tissue such as a synovial membrane, synovial bursa, cartilage, etc. Accordingly, when inserting theprobe 44 and thesheath 51 into thejoint cavity 17, there is no need to switch treatment tools, thereby improving workability. - As shown in
FIG. 5 , there is a case where a doctor places theprobe 44 and thearthroscope 18 so that the distal end portion of theinsertion section 23 of thearthroscope 18 is placed close to theexcision region 63 side of theprobe 44. The doctor can transmit ultrasonic vibration to theprobe 44 when pressing theenergy input button 52 while theexcision region 63 of theprobe 44 is brought into contact with a bone spur, etc. of the bone 12 (living tissue) to be treated under the operation of thearthroscope 18. By this process, removal or excision of a hard tissue to be treated such as a bone can be accomplished. At this time, it is likely that theinsertion section 23 of thearthroscope 18 is placed close to theprobe 44 as shown inFIG. 5 . In such a case, theexcision region 63 side of theprobe 44 is protected by thesecond portion 65 extending relative to thefirst portion 64 of thesheath 51. Accordingly, the ultrasonically vibratingprobe 44 is prevented from coming into contact with theinsertion section 23 of thearthroscope 18. Thus, in the case where theinsertion section 23 of thearthroscope 18 is located near theexcision region 63 of theprobe 44, theinsertion section 23 of thearthroscope 18 is placed close to or in contact with thesheath 51, to be prevented from coming in contact with theprobe 44, thereby preventing theprobe 44 from being broken (or damaging the arthroscope 18) at thetreatment section 61A, for example. - According to the first embodiment, the
ultrasonic treatment apparatus 15 used for surgery using thearthroscope 18 comprises; theprobe 44 including themain body section 61 to which ultrasonic vibration is transmitted, theexcision region 63 which is provided at the distal end side of themain body section 61 and excises a bone by the ultrasonic vibration, thesheath 51 including thefirst portion 64 that covers themain body section 61 of theprobe 44, and thesecond portion 65, which extends from thefirst portion 64 to cover the side where theexcision region 63 of themain body section 61 is provided. - With this configuration, the
second portion 65 is provided to cover the side where theexcision region 63 of theprobe 44 is provided, thereby preventing a problem that theprobe 44 to which ultrasonic vibration is transmitted is in contact with thearthroscope 18. - The
main body section 61 has the bendingportion 62 that is bent relative to the longitudinal axis C of themain body section 61, and thesecond portion 65 of thesheath 51 covers the side of the bendingportion 62 where theexcision region 63 is defined. With this configuration, the portion corresponding to the bendingportion 62 of theprobe 44 which has the largest curvature and is easiest to be broken can be protected by thesecond portion 65. Accordingly, even if a doctor unintentionally brings theprobe 44 close to thearthroscope 18 during surgery, thearthroscope 18 is not brought into contact with the portion corresponding to the bendingportion 62 of theprobe 44. - Thus, the
probe 44 can be prevented from being broken at a position where the bendingportion 62 is provided. In addition, thesecond portion 65 has a shape of Substantially half of the cylinder which can be simply accomplished. Therefore, even if thesecond portion 65 is provided, an increase in the manufacturing costs can be suppressed. - A
treatment system 11 according to the second embodiment will be described with reference toFIGS. 6 to 8 . Thetreatment system 11 of the second embodiment is different from thetreatment system 11 of the first embodiment in that asecond sheath 76 and asuction path 71 are provided inside of asheath 51 of anultrasonic treatment apparatus 15, but the other structures are identical to those of the first embodiment. Accordingly, mainly portions different from the first embodiment will be explained, and portions the same as the first embodiment will not be explained or shown in the drawings. - As shown in
FIGS. 6 to 8 , ahandpiece 41 of theultrasonic treatment apparatus 15 includes a rod-like probe 44, a hollow (a tubular shape such as a cylindrical shape)sheath 51 which covers the periphery of theprobe 44 to protect theprobe 44, a second sheath 76 (tubular member) which is a tubular shape such as a cylindrical shape and provided inside of thesheath 51, asuction path 71 provided between thesheath 51 and thesecond sheath 76, aconnection cap 72 connected to thesuction path 71, and an energy input button 52 (switch) provided to ahousing 47. - As shown in
FIG. 6 , theultrasonic treatment apparatus 15 is also provided with asuction source 73 which includes a vacuum pump, etc, and causes negative pressure in the suction path, and with atank 74 to store suctioned liquid or living tissue between thesuction path 71 and thesuction source 73. Thesuction path 71 is connected to thesuction source 73 through theconnection cap 72 and atube 75 connected thereto. - As shown in
FIGS. 6 and 7 , the second sheath 76 (tubular member), which is an inner sheath, is interposed between thefirst portion 64 of thesheath 51, which is an outer sheath, and theprobe 44. Thesecond sheath 76 is provided to cover the probe 44 (main body section 61). In the embodiment, thesecond sheath 76 is arranged to be eccentric relative to a central axis D of thesheath 51. Thus, a central axis C of thesecond sheath 76 is shifted relative to the central axis D of thesheath 51. As shown inFIG. 8 , thesecond sheath 76 includes aproximal part 76A close to apart 51A on an inner peripheral surface of thesheath 51, and adistal part 76B opposite to theproximal part 76A. - As shown in
FIGS. 7 and 8 , thesuction path 71 is provided in a space between the inner side of thefirst portion 64 of thesheath 51 and the outer side of thesecond sheath 76. Specifically, thesuction path 71 is provided between thedistal part 76B and the inner peripheral surface of the sheath 51 (positioned away from thepart 51A of the inner peripheral surface of the sheath 51). Thesuction path 71 includes asuction opening 71A exposed to the outside at the distal end direction C1 side. - A surgical method using the
treatment system 11 according to the present embodiment will be described with reference toFIGS. 6 to 8 . - A
joint cavity 17 is filled with perfusate by a well-known method. Anarthroscope 18 is inserted into thejoint cavity 17 from a suitable portal to check the condition of a patient. A doctor uses another portal to insert theprobe 44 and thesheath 51 of thehandpiece 41 into thejoint cavity 17. When inserting theprobe 44 into thejoint cavity 17, theprobe 44 to which ultrasonic vibration is transmitted can be used for removal of an intervening soft tissue such as a synovial membrane, synovial bursa, cartilage, etc., similar to the first embodiment. - As shown in
FIG. 5 , a doctor places theprobe 44 and thearthroscope 18 so that the distal end portion of thearthroscope 18 is placed near thesheath 51 at theexcision region 63 side of theprobe 44. The doctor can transmit ultrasonic vibration to theprobe 44 when pressing theenergy input button 52 while theexcision region 63 of theprobe 44 is brought into contact with a bone spur, etc. of the bone 12 (living tissue) to be treated under the operation of thearthroscope 18. By this process, removal or excision of a hard tissue to be treated, such as a bone can be accomplished. In this case, theexcision region 63 side of the probe 44 (portion corresponding to a bending portion 62) is protected by asecond portion 65 of thesheath 51. Accordingly, theprobe 44 is prevented from being broken by coming in contact with thearthroscope 18 while ultrasonic vibration is transmitted to theprobe 44. - According to the present embodiment, in the state where the
ultrasonic treatment apparatus 15 of thetreatment system 11 is powered on, thesuction source 73 is in continuous operation, and a fragment of a living tissue or an air bubble generated at theexcision region 63 can be suctioned and removed through thesuction source 73. In addition, according to the present embodiment, since thesecond sheath 76 is provided to be eccentric relative to the central axis D of thesheath 51, the diameter of thesuction path 71 and thesuction opening 71A is ensured to be relatively large. Thus, it is possible to suction a fragment of a bone which is relatively large through thesuction opening 71A and thesuction path 71. - According to the present embodiment, a tubular member provided to cover the
probe 44 between thefirst portion 64 of thesheath 51 and theprobe 44, and thesuction path 71 provided in a space between thefirst portion 64 and the tubular member and connected to thesuction source 73 are provided. - With this configuration, a fragment of a living tissue or an air bubble generated by treatment can be removed through the
suction path 71, thereby ensuring a clear view under an arthroscope. In particular, a fragment can be suctioned and removed near a place where the fragment is generated (theexcision region 63 of the probe 44), thereby removing the fragment before being diffused to the periphery. Accordingly, it is possible to remove a fragment efficiently and to reliably provide a clear view under an arthroscope while preventing cloudiness of the perfustate. Small fragments such as powdered fragments rise to obstruct a field of view of thearthroscope 18. Accordingly, it is extremely efficient to remove such fragments near theexcision region 63 in order to perform surgery effectively and safely. - The tubular member includes the
proximal part 76A provided to be eccentric relative to the central axis D of thesheath 51 and close to thepart 51A on an inner peripheral surface of thesheath 51, and thedistal part 76B opposite to theproximal part 76A, and thesuction path 71 is provided between thedistal part 76B and a position away from thepart 51A on an inner peripheral surface of thesheath 51. - With this configuration, the diameter of the
suction path 71 is ensured to be large in comparison with the case where the tubular member is provided so that the central axis C of the tubular member matches the central axis D of thesheath 51. Accordingly, it is possible to suction and remove not only small powdered fragments, but also a fragment having a relatively large diameter, thereby improving fragment removal efficiency. Therefore, it is possible to ensure a clear view under thearthroscope 18 and to promote safety of surgery. - A treatment system according to the third embodiment will be described with reference to
FIGS. 9 and 10 . Thetreatment system 11 of the third embodiment is different from thetreatment system 11 of the second embodiment in that asecond portion 65 of asheath 51 of anultrasonic treatment apparatus 15 has anotch 81, but the other structures are identical to those of the second embodiment. Accordingly, mainly portions different from the second embodiment will be explained, and portions the same as the second embodiment will not be explained or shown in the drawings. - As shown in
FIGS. 9 and 10 , thesheath 51 includes afirst portion 64 having a tubular shape such as a cylindrical shape, and asecond portion 65 extending from thefirst portion 64. Thesecond portion 65 is provided at a side where anexcision region 63 is provided. For example, thesecond portion 65 is provided to correspond to an angle of 180° around the longitudinal axis C. Thesecond portion 65 has anotch 81 which is a slit-like portion extending toward the proximal end direction C2 from the distal end of thesecond portion 65. Thenotch 81 includes amain body part 81A extending linearly along the longitudinal axis C, and an arch-shapedbottom part 81B provided at an end of the proximal end direction C2 side of themain body part 81A. The length of thenotch 81 along the longitudinal axis C is substantially the same as the length of thesecond portion 65 along the longitudinal axis C. - The
notch 81 may be provided to span across thesecond portion 65 and thefirst portion 64, not only in thesecond portion 65. In this case, it is preferable that thenotch 81 extends from the distal end portion of thesecond portion 65 to the proximal end direction C2 side, and thebottom part 81B of thenotch 81 is located closer to the distal end direction C1 side than a node position 55 (a node position closest to the distal end direction C1 side) of ultrasonic vibration transmitted to theprobe 44. - The width in the direction crossing the longitudinal axis C of the
notch 81 is set to be smaller than the diameter of anarthroscope 18 to be used. More specifically, a diameter D1 of thearthroscope 18 is set to be within the range of 2<D1<10 (mm), for example, while a size D2 of thenotch 81 is set to be within the range of 1≤D2≤10 mm), for example. - A surgical method using the
treatment system 11 according to the present embodiment will be described with reference toFIGS. 9 and 10 . - A
joint cavity 17 is filled with perfusate by a well-known method. Thearthroscope 18 is inserted into thejoint cavity 17 from a suitable portal to check the condition of a patient. A doctor uses another portal to insert theprobe 44 and thesheath 51 of thehandpiece 41 into thejoint cavity 17. When inserting theprobe 44 into thejoint cavity 17, theprobe 44 to which ultrasonic vibration is transmitted can be used for removal of intervening soft tissue such as a synovial membrane, synovial bursa, cartilage, etc., similar to the other embodiments. - As shown in
FIG. 5 , a doctor places theprobe 44 and thearthroscope 18 so that the distal end portion of thearthroscope 18 is placed near thesheath 51 at theexcision region 63 side of theprobe 44. The doctor can transmit ultrasonic vibration to theprobe 44 when pressing anenergy input button 52 while theexcision region 63 of theprobe 44 is brought into contact with a bone spur, etc. of the bone 12 (living tissue) to be treated under the operation of thearthroscope 18. By this process, removal or excision of a hard tissue to be treated such as a bone can be accomplished. In this case, theexcision region 63 side of theprobe 44 is protected by thesecond portion 65 of thesheath 51. Accordingly, theprobe 44 is prevented from being broken by coming in contact with thearthroscope 18 while ultrasonic vibration is transmitted to theprobe 44. - In the present embodiment, the slit-
like notch 81 is provided to thesecond portion 65. Accordingly, even if an operation is performed under the condition shown inFIG. 5 , theprobe 44 and theexcision region 63 can be visually recognized through thenotch 81 under thearthroscope 18. Accordingly, the present embodiment realizes further improvement of efficiency and safety in the surgery. - Furthermore, according to the present embodiment, in the state where the
ultrasonic treatment apparatus 15 of thetreatment system 11 is powered on, asuction source 73 is perpetually actuated, and a fragment of a living tissue or an air bubble generated at theexcision region 63 can be suctioned and removed through thesuction source 73. In addition, according to the present embodiment, since asecond sheath 76 is provided to be eccentric relative to the central axis D of thesheath 51, the diameter of asuction path 71 and asuction opening 71A is ensured to be large so that a large fragment can be suctioned, similar to the second embodiment. - According to the present embodiment, the
second portion 65 has thenotch 81 which extends toward the proximal end direction C2 side which is opposite to the distal end direction C1 side of amain body section 61. With this configuration, when thearthroscope 18 is used at theexcision region 63 side of theprobe 44 for operation, theprobe 44 and theexcision region 63 are not hidden by thesecond portion 65 for protecting theprobe 44, and the visual recognition of theprobe 44 and theexcision region 63 can be improved. Accordingly, a doctor can perform surgery efficiently and safely. - Furthermore, the width of the
notch 81 in the direction crossing the longitudinal axis C of thenotch 61 is set to be smaller than the diameter of thearthroscope 18 to be used in the arthroscopic surgery. With this configuration, thearthroscope 18 is not erroneously inserted into thenotch 81 even if thenotch 81 is provided to thesecond portion 65. Thus, a problem of thearthroscope 18 and theprobe 44 coming in contact with each other due to thenotch 81 can be prevented. - The present invention is not limited to the above-described embodiments, and can be modified in various manners when reduced to practice, without departing from the gist of the invention. In addition, the
treatment system 11 according to each embodiment can of course be combined to function as a treatment system. - Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
