Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic surgical apparatus for performing various surgical operations such as coagulation, incision, and puncture on living tissue by ultrasonic waves.

[0002]

2. Description of the Related Art There have been proposed various ultrasonic surgical apparatuses for performing a surgical operation such as coagulation, incision or puncture on a living tissue by ultrasonic waves. For example, there is an ultrasonic scalpel device as described in JP-A-9-38098. Generally, an ultrasonic operation apparatus includes a handpiece having an ultrasonic vibrator built therein, and an ultrasonic vibration transmitting member for transmitting ultrasonic vibration to a treatment section. The handpiece and the ultrasonic vibration transmission member are separate members, and a probe of another member is connected to the horn of the handpiece so that the probe can be attached and detached by screwing.

[0003]

SUMMARY OF THE INVENTION In order to detect the limit of use of an ultrasonic surgical apparatus, information specific to a handpiece is managed on the ultrasonic oscillation output generator side, and discrimination is made from a record of the number of times of use and the state of use. Is being done. in this case,
In practice, the service life of the probe is lower than the service life of the handpiece, and only the probe may be replaced.

[0004] As described above, in the conventional system, the handpiece is managed because only the probe is exchanged and used. However, a desirable system can be constructed if the unique information of the handpiece is obtained and the life of the probe itself can be predicted.

Further, when performing a surgical operation such as coagulation, incision or puncture on a living tissue by ultrasonic waves, it is not always the case that only one ultrasonic surgical apparatus is used. For example, in laparoscopic surgery, multiple ultrasonic trocar mantles are used. In this case, a trocar tube of a plurality or various thicknesses is used, and an ultrasonic probe (needle) suitable for the trocar tube to be punctured into the abdominal wall is selected, and the ultrasonic probe is connected to the trocar tube. Used in assembly. After puncturing the abdominal wall, only the ultrasonic probe with the handpiece is pulled out, leaving only the trocar mantle tube. If the ultrasonic probe can be used by attaching it to a new trocar mantle tube to be punctured next, it can be used with the handpiece attached. The ultrasonic probe must be reattached to the handpiece before use. These operations were complicated and the operation could not be performed quickly.

However, it is conceivable to prepare a plurality of handpieces each having an ultrasonic probe suitable for a plurality of trocar mantle tubes having different diameters. However, in this case, there are multiple output cables connected to each handpiece, and there are other high-frequency output cables or cables such as water supply tubes and air supply tubes near this unit, so their handling is troublesome. And
These cables are easily entangled, resulting in a rather complicated work environment.

Further, since the connector port of the ultrasonic oscillation output generator is usually one, the output cable of the target handpiece is determined from a plurality of output cables, and the connector is connected to the connector port or replaced. Alternatively, it is necessary to check the connection state, which is troublesome. Especially since the ultrasonic oscillation output generator is installed at a position far from the sterilization area of the surgical operation,
Often, they had to rely on assistants to perform those tasks. Even asking for helpers, the coordination was cumbersome and inefficient.

The ultrasonic probe is usually detached from the handpiece and stored, and when used, an operator or a nurse uses a special spanner or tool to attach the probe to the thread on the horn of the handpiece. The screw part provided at the base end is screwed in to assemble them.

However, if the screwing force is small, there is a possibility that the screw connection portion may be damaged or generate heat during use, resulting in overheating. For this reason, there is a tendency that the screw is inevitably screwed in with a spanner and screwed too much. If the screw is screwed in too hardly, the screw connection may be damaged, or even if it is not damaged, the vibration transmission performance may be adversely affected.

Therefore, as known from US Pat. No. 5,776,155, a special tool has been proposed to keep the screwing amount properly, but even in such a case, management and labor are complicated.

Further, since the ultrasonic probe is screwed and connected to the handpiece, the position of the ultrasonic probe around the axis of the ultrasonic probe easily changes with respect to the handpiece depending on the screwing strength. That is, it was difficult to always attach the ultrasonic probe to the handpiece in a fixed direction.

When the shape of the treatment portion of the ultrasonic probe is not uniform around the axis, the cutting edge is formed to be slightly flat so that it can be punctured along the muscle of a tissue like an ultrasonic trocar, for example. In such a case, it is often necessary to change the direction of the treatment section of the ultrasonic probe by turning the handpiece to be gripped. For this reason, the handpiece cannot always be gripped in the same position at the same position where it can be easily held. That is, it is necessary to confirm the direction of the treatment section of the ultrasonic probe for each instrument and change the gripping state of the handpiece.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to obtain an optimum use state stably and to improve the simplicity of handling. It is an object of the present invention to provide an ultrasonic surgical apparatus capable of recognizing a use state.

To communicate.

As shown in FIG. 3, the ultrasonic vibrator 12 has a plurality of piezoelectric elements 10 superposed on each other, and ultrasonic vibration is generated by applying a driving voltage through the electrodes.
The ultrasonic vibration amplitude is enlarged and amplified via a horn 13.

The ultrasonic vibration transmitting member 15 is fixedly connected to the horn 13 of the ultrasonic vibrator 12,
The two members have a structure that cannot be attached or detached during normal use, and are handled as a single unit as long as they are used normally.

As a method of fixedly connecting the horn 13 of the ultrasonic vibrator 12 and the ultrasonic vibration transmitting member 15, for example, those listed in FIG. 5 can be considered. FIG.
(C) shows the horn 13 and the ultrasonic vibration transmitting member 1
Reference numeral 5 denotes a separate member, which is a case where both members are fixedly connected.

FIG. 5 (a) shows a case where a female screw 16 is formed at the tip of the horn 13 while the ultrasonic vibration transmitting member 15 is formed.
A male screw 17 is formed at the base end of the

You may make it bond the said fitting part or between end surface joining surfaces with an adhesive agent. Further, the members provided with the holes 18 and the protrusions 19 may be reversed.

FIG. 5D shows an integrated system in which both parts of the horn 13 and the ultrasonic vibration transmitting member 15 are formed by a single member and both members are fixedly connected.

The system in which the horn 13 and the ultrasonic vibration transmitting member 15 are fixedly connected in a state where they cannot be detached is not limited to the above-described example. For example, even when the horn 13 and the ultrasonic vibration transmitting member 15 are screw-coupled, an integrated structure employing a detachable preventing means that the user cannot remove the ultrasonic vibration transmitting member 15 from the horn 13 may be used. As the attachment / detachment prevention means, there is a structure or the like that covers a portion where a tool is applied to the ultrasonic vibration transmission member 15 so that a user cannot see it.

The mantle tube 5 attached to the handpiece 6
Is configured as follows. That is, the sheath 21 and the holding portion 22 are provided, and the holding portion 22 is provided at the base end of the sheath 21.
Is connected. The conduit of the sheath 21 communicates with a space formed in the holding section 22. A lid 23 is provided at a base end side opening of the holding part 22, and a seal member 24 is detachably attached to the lid 23. The seal member 24 is sandwiched and attached between a seal fixing member 26 rotatably provided on the lid 23 via a shaft 25 and the lid 23.
Therefore, if the seal fixing member 26 is rotated and separated from the lid 23, the seal member 24 sandwiched therebetween can be removed.

The lid 23 is provided with a flap valve (not shown). This flap valve is usually located at a position where the proximal opening of the holding portion 22 is closed by a spring (not shown),
When the trocar needle or the handpiece 6 is attached, the flap valve is rotated by pushing the push button 27, and the flap valve is retracted to the side of the space inside the holding unit 22 to open the base end side opening of the holding unit 22. I can do it.

Further, the seal member 24 is provided with a first seal hole and a second seal hole which are held at the position of the base end side opening of the holding portion 22, and the diameter of the second seal hole is larger than the diameter of the first seal hole. The diameter is set small. The second seal hole is the holding part 2
2 is provided on a valve member 28 detachable from the valve member 2.
8 is formed at the tip of an arm member 29 extending from the holding portion 22. The valve member forming the first seal hole is a holding portion 22.
Is held in. The holding part 22 is provided with a base 30 communicating with the conduit of the sheath 21.

The lid 23 of the holding portion 22 of the outer tube 5 is provided with a means for detachably connecting the handpiece 6. This connecting means is configured, for example, as shown in FIG. A cylindrical connecting member 41 is coaxially connected and fixed to the tip of the case 11 of the handpiece 6 by screwing or the like. A connection ring 42 is coaxially and rotatably connected to the distal end of the connection member 41. That is, a projection 43 and a groove 44 are formed annularly on the inner surface at the distal end of the connection member 41 over the entire circumference, and a projection 46 and a groove 4 are formed over the entire circumference on the outer surface of the base end of the connection ring 42.
The protrusion 7 is formed in an annular shape, and the protrusion 43 and the groove portion 44 are formed in a reversed manner so that the protrusion 46 and the groove portion 47 mesh with each other. Therefore, the connection ring 42 can rotate coaxially with respect to the connection member 41. However, due to the frictional force of the meshing connection, the rotation of the two members with a light force is suppressed, and the two members cannot be rotated unless the operation of rotating with a relatively strong force is performed.

The outer tube 5 is connected to the rotatable connection ring 42. That is, on both sides of the lid portion 23 of the mantle tube 5, a piece-like receiving portion 50 extending in the proximal direction is provided.
A projection 51 and a groove 52 are formed on the inner surface of the distal end of the receiving portion 50. A locking arm (claw) 53 bulging outward and projecting forward is provided on both sides of the distal end of the connection ring 42 so as to correspond to the receiving portions 50. On the outer surface of the distal end of the locking arm 53, a projection 55 and a groove 56 which are opposite to the concave and convex are formed so as to mesh with the projection 51 and the groove 52 of the receiving portion 50.

In such a configuration, when the handpiece 6 is mounted on the mantle tube 5, the projections 51 and 55 with the locking arms 53 deformed inward climb over the peaks and engage with each other to be locked. In order to remove, the engagement arm 53 is deformed inward with a finger or the like to release the engagement, and in this state, the handpiece 6 can be removed from the mantle tube 5 by pulling the handpiece 6 toward the user.

At the rear end of the handpiece 6, there is provided an electric connection portion 58 to which a connector 57 of the cable 3 can be attached and detached. The electrical connection portion 58 is configured to be able to connect the connector 57 of the common cable 3 even if it is of the handpiece 6 of the ultrasonic surgical device 1 of a different type.
Therefore, the ultrasonic surgical apparatus 1 is the same kind of handpiece 6.
However, even if the handpieces 6 are of different types, the common cable 3 can be connected. For this reason, the cable 3 connected to the oscillation device 2 can be shared, and there is no need to prepare the cable 3 individually for each handpiece 6 to be used.

FIG. 7 shows a plurality of ultrasonic trocars having the same structure as described above.
This is an ultrasonic surgical apparatus 1 in a case where φ10 and φ12 are different. The relationship is such that a common cable 3 can be connected to any of the ultrasonic surgical apparatuses 1.

FIG. 8 shows the relationship between a plurality of ultrasonic surgical apparatuses 1 to which a common cable 3 can be connected, including the different models, and the relationship between treatment tools combined with each transducer unit.

FIG. 8A shows an example of the vibrator unit 73 when the treatment tool 71 is a scissor and the diameter of the insertion portion 72 is φ10, and FIG. 8B shows that the treatment tool 74 is a short scissor. FIG. 4C shows an example of the vibrator unit 76 when the diameter of the insertion portion 75 is also φ10, and FIG. 4C shows the vibrator unit 79 when the treatment tool 77 is a scissor and the diameter of the insertion portion 78 is φ5. FIG. 4D shows an example of the vibrator unit 83 in the case where the treatment tool 81 is a hook and the diameter of the insertion portion 82 is φ10. FIG. 4E shows the case where the treatment tool 84 is a hook and the insertion thereof. This is an example of the vibrator unit 86 when the diameter of the portion 85 is φ5.

Each of the treatment tools 71, 74, 77, 81,
Transducer units 73, 76, 79, 8 used for 84
The common cable 3 can also be connected to 3,86. In addition, a common cable 3 can be connected to any of the transducer units, even if the treatment tools are of the same type but of different types or of different types.

The treatment tools 71, 74, 77, 81, 8
4 is a corresponding transducer unit 73, 76, 7
Although 9, 83 and 86 are used, it is desirable to provide an identification (determination) means in order to clarify the applicable relationship between the two. For example, a common color, a character, a symbol, a number, and the like, which can be discriminated, are attached to the applicable two types.

FIG. 9 shows an example in which an identification (determination) means is added to an example of an ultrasonic trocar as a treatment tool.
Colors, letters, and characters common to both the three mantle tubes 5 having different diameters and the ultrasonic vibrator unit of the handpiece 6 to which the ultrasonic vibration transmitting member 15 applicable to each of them is fixed.
Symbols, numbers, etc. are displayed.

Generally, the oscillation device 2 is provided with one socket 88 for connecting the connector 87 of the cable 3, but when a plurality of sockets 88 are provided, a plurality of cables 3 may be used. However, if the number of the cables 3 is large, it tends to hinder the work, so that the number of the treatment tools to be used should be considerably smaller than the number of the treatment tools to be used.

By the way, each of the handpieces 6 is provided with a discriminating means for identifying itself. As shown in FIG. 3, the handpiece determining means in this embodiment incorporates a resistance element 61 in the handpiece 6,
The resistance value of the resistance element 61 is read by a detection circuit 62 incorporated in the oscillation device 2, and the type of the handpiece 6 incorporating the resistance element 61, that is, the transducer unit integrated with the probe is determined. FIG.
An example of the correspondence between the resistance of the handpiece and the type of the handpiece is shown.

The oscillating device 2 that recognizes the type of the individualized vibrator unit controls a frequency, a voltage, a current, or the like suitable for the power supplied to the recognized vibrator unit. The oscillation device 2 stores the number of times of use of the vibrator unit, the frequency at the time of use, the voltage or the current, etc. as data. Then, based on the stored data, the usage amount of the storage vibrator unit is integrated. The data of the used amount can be displayed on the display 63, but the fact of the vibrator unit near the end of its life is notified in advance by a display or a warning sound.

When constructing an ultrasonic trocar, the ultrasonic surgical apparatus 1 according to the present embodiment is separated into a mantle tube 5, a handpiece 6 with a probe, and a cable 3 as shown in FIG. When using the ultrasonic surgical apparatus 1, the mantle tube 5, the handpiece 6, and the cable 3 are assembled as shown in FIG. As shown in FIG. 7, the mantle tube 5 and the handpiece 6 are used in combination of a plurality of suitable ones. A plurality of sets of mantle tubes 5 and handpieces 6 are used, but the cable 3 is shared. Therefore, the cable 3 connected to the oscillation device 2 can be shared by a plurality of handpieces 6, and there is no need to prepare each set of cables 3.

When there are cables 3 for each of a plurality of sets, it is necessary to select the cable 3 of the ultrasonic surgical apparatus 1 to be used and connect it to the oscillation apparatus 2 in many cases.
Not only cable 3 but also cables for high frequency output or cables such as water supply tube and air supply tube.
They are easily entangled, and the tubes are entangled, resulting in a complicated state. It is quite troublesome to find a specific cable from such complicated tubes.
In addition, since the oscillating device 2 is often set apart from the operating table, there is an inconvenience, such as an operation of connecting a specific cable 3 to the oscillating device 2 at a distance.

However, in the present embodiment, since the cable 3 connected to the oscillation device 2 can be shared by a plurality of ultrasonic surgical devices 1, those inconveniences and inconveniences are resolved, and the vicinity can be obtained without relying on an assistant. The connection work can be performed immediately, and the handling is simple and the work can be performed efficiently.

Further, in this embodiment, since the handpiece 6 and the ultrasonic vibration transmitting member 15 are integrally and fixedly connected, when the ultrasonic surgical apparatus 1 is used,
In each case, since the work of assembling the ultrasonic vibration transmitting member (probe) 15 to the handpiece 6 is not required, it is possible to quickly assemble and use the handpiece 6 without mistake.

Conventionally, the probe was assembled each time the probe was screwed into the handpiece.
In that case, it was necessary to assemble by selecting the correct one without mistake, so that over tightening or insufficient tightening would not occur. According to the embodiment,
These disadvantages are eliminated. According to the present embodiment, work efficiency is improved.

Further, since the handpiece 6 and the ultrasonic vibration transmitting member 15 are integrally and fixedly connected to each other and have an unified structure with no excessive or insufficient tightening of the screws, the ultrasonic It is possible to provide an efficient ultrasonic surgical apparatus 1 having an efficient transmission performance, a stable operation state, and low heat generation.

In this embodiment, the mantle tube 5
And the handpiece 6 detachably attached to the
Since it is relatively rotatable around the axis, only the direction of the ultrasonic vibration transmitting member 15 of the handpiece 6 can be changed. The direction of the ultrasonic vibration transmission member 15 and the treatment section 14 can be changed to a direction that facilitates treatment without changing the holding state.

Further, in this embodiment, the handpiece 6
The treatment section 1 is determined by the resistance element 61 of the determination means incorporated in the
It is possible to manage the usage amount, the life, and the like of the ultrasonic vibration transmission member 15 including 4. In the case of the detachable structure in which the user can separate the ultrasonic vibration transmitting member 15 from the handpiece 6, the discriminating means incorporated in the handpiece 6 cannot directly manage the usage amount, the life, and the like of the ultrasonic vibration transmitting member 15. However, in the present embodiment, it is possible to accurately grasp. The ultrasonic vibration transmitting member 15 is a particularly important function in a situation where the durability of the handpiece is lower than that of the handpiece, and the ultrasonic vibration transmitting member 15 is easily worn out first.

(Second Embodiment) A second embodiment of the present invention will be described with reference to FIGS. Except for the matters described below, the configuration is basically the same as that of the first embodiment.

In the above-described first embodiment, the connector 57 of the common cable 3 can be connected to the electric connection portion 58 of the handpiece 6 of each ultrasonic surgical apparatus 1.

The locking projection 98 of the claw 95 enters the inner groove 93 and goes over the locking projection 94 to be locked (FIG. 11).
State indicated by a two-dot chain line). That is, the connector 57 is engaged and connected to the electric connection portion 58 of the handpiece 6. The handpiece 6 and the connector 57 are connected so as to be relatively rotatable around an axis.

From the outside of the cylindrical connecting portion 91, the elastic piece 97 is
When the bulging portion 100 is pushed in, the locking projection 98 of the claw 95 is disengaged from the projection 94, and the connector 57 can be removed from the handpiece 6.

Next, an electrical connection structure between the handpiece 6 and the connector 57 will be described. The first to fourth electrodes 101 and 10 are provided on the end face of the electric connection portion 58 of the handpiece 6.
2, 103 and 104 are provided. As shown in FIG. 12, the first electrode 101 is formed in a point shape at the center axis of the electric connection portion 58, and the second to fourth electrodes 102 and 10 are formed.
Each of the reference numerals 3 and 104 is formed in a ring shape, and is concentrically arranged around the first electrode 101 located at the central axis of the electric connection portion 58.

On the other hand, on the connector 57 side, first to fourth electrodes 106, 107, 1 each formed in a contact pin shape.

The set of 08 and the fourth electrodes 104 and 109 are used for signal transmission of the resistance element 61 of the handpiece determining means.

In the present embodiment, since the connector 57 of the cord 3 is rotatable with respect to the handpiece 6, the twist of the cord 3 generated when the handpiece 6 is used can be eliminated. Also, even if the operation of rotating the handpiece 6 is performed, the cord 3 is not twisted.
Can be rotated lightly. Furthermore, since the handpiece 6 is rotatable with respect to the mantle tube 5, the handpiece 6 can easily take various postures, and the operability of the handpiece 6 is improved. Note that the present invention is not limited to the above embodiment.
