Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a surgical microscope.

[0002]

2. Description of the Related Art In recent years, with the advancement of surgical techniques,
Surgical microscopes have come to require various additional functions. Examples of devices for performing such additional functions include, for example, an imaging device such as a video camera used by an assistant to assist surgery or used for education of a surgical technique, and reducing fatigue of an operator. Examples include an auto-focus device that automatically focuses to enhance workability, a laser treatment device corresponding to each case, and a laser protection shutter device that protects an operator's eyes from a laser beam generated by the laser treatment device.

[0003] These additional functions are used in different manners depending on the operation technique, operator's preference, and the like, and if all functions are provided in one surgical microscope, it becomes considerably expensive. The above-described devices for performing additional functions are generally unitized and retrofitted to the basic operating microscope as an accessory.

[0004] When such an accessory is retrofitted to an operating microscope, cables for operating the accessory are separately required. The more attachments that can be attached, the greater the number of such cables.
Such cables are usually crawled around the surgical microscope in a bare state, and are only partially clamped (collected) with a binder or the like.

Further, in order to avoid such a bare state of the cables, all the cables for operating the accessory device are built in the microscope side in advance, and the attachment / detachment portion is connected to the attachment / detachment portion on the accessory device side. In some cases, only one is provided.

[0006]

However, in a situation where a considerable number of cables are merely clamped by a binder or the like in a state where the cables are exposed, if something gets caught on these cables, In addition, it is expected that not only may the cables be disconnected, but also the pulling of the cables may cause the arm holding the microscope to move irrespective of the surgeon's will, thereby hindering the operation.

Further, it is necessary that the cables have a sufficient length so that they do not protrude and hinder the movable range of the arm. May hinder the field of view, which is not practically preferable.

On the other hand, when all the cables are built in the microscope and only the electrical contacts are provided in the attachment / detachment portion of the accessory device, the above-mentioned problem does not occur because the cable is not exposed. Even when the device is not used, it is necessary to provide a contact portion for electrically connecting to an electrical contact of the attached device on the microscope side, so that the microscope becomes expensive accordingly. In addition, the fact that there is an electric contact for each attachment / detachment part of the attachment device may impair the reliability accordingly.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a cable which can be stored without exposing cables, and which can be installed at low cost and can be retrofitted with an attached device. It is to provide a high operating microscope.

[0010]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a surgical microscope in which an accessory device having a cable for supplying power or transmitting a signal is detachably attached. A groove which is possible and is separated from the internal structure of the microscope is formed on the outer surface of the body of the microscope, and a lid for closing the groove and smoothing the outer surface of the body of the microscope is detachable. I do.

In the surgical microscope according to the present embodiment, the built-in cables 16 and 17 on the microscope side are not in contact with the built-in components of the microscope (the storage groove 1 is separated from the internal structure of the microscope).
4, in other words, the cable 1
Since the storage grooves 14 for storing 6, 17, 24, and 28 are separated from the internal structure of the microscope, when attaching an auxiliary device such as the autofocus unit 21 or the laser protection shutter device 30 to the microscope main body 11, the microscope can be used. Cables can be easily connected without worrying about accidentally touching the built-in components or getting dust inside the microscope.

Further, the operating microscope according to the present embodiment has a storage groove 14 in which the cables 16, 17, 24, 28 are stored.
Is closed by the smooth lid 20, so that the cables 16, 17, 24, and 28 are not exposed to the outside, and the external shape of the microscope main body 11 after storing the cables is changed. Without the need for additional equipment.

FIGS. 8 and 9 show a second embodiment of the present invention.
Is shown in In the surgical microscope of the present embodiment, the groove for accommodating the cable is different from that of the first embodiment, and the other portions are the same as those of the first embodiment. The description is omitted.

FIG. 8 shows a state in which the autofocus unit 21 and the laser protection shutter device 30 are attached to the microscope main body 11 of the surgical microscope. The storage groove 14 is formed in the microscope main body 11 in substantially the same manner as in the first embodiment, but the first groove 14 a that forms the storage groove 14 is formed.
Is opened on the side surface of the microscope main body 11 facing the mirror holding arm 9.

Mirror holding arm 9 facing microscope body 11
The side surface of the housing extends vertically and one end thereof is
A storage groove 35 connected to the first groove portion 14a is formed. Further, on the side surface of the second arm 7, the storage groove 3 is provided.

FIG. 9 shows the three storage grooves 14, 35, 3
6 shows lids 20, 37, 38 for closing 6. The lid 20 shown in FIG. 9A is for closing the storage groove 14, and is exactly the same as that shown in FIG. The lid 37 shown in FIG. 9B is for closing the storage groove 35 and is formed in a straight plate shape. The lid 38 shown in FIG. 9C is for closing the storage groove 36, and is formed in an L-shape corresponding to the shape of the storage groove 36. Note that a double-sided tape is attached to the back surfaces of the lids 20, 37, and 38.

In the above configuration, the autofocus unit 21 and the laser protection shutter device 30 are connected to the microscope main body 1.
After being attached to 1, the cable 24 on the side of the autofocus unit 21 and the cable 28 on the side of the laser protection shutter device 30 are routed from the storage groove 14 to the storage groove 36 via the storage groove 35. The distal ends of the cables 24 and 28 are extended through the storage grooves 36 and connected to a power supply unit (not shown) near the gantry 1 by a connector.

Therefore, according to the surgical microscope of the present embodiment, the same effect as that of the first embodiment can be obtained, and the built-in cable 16 for making the accessory device function as in the first embodiment. , 17 do not need to be built into the base microscope side, that is, it is not necessary to provide a contact portion for electrically connecting to an electrical contact of an accessory device on the microscope side, so that the surgical microscope is inexpensive. In addition, even if the cable breaks, repair becomes easy.

A third embodiment of the present invention is shown in FIGS. The surgical microscope according to the present embodiment is the second type.
Since the present embodiment is a modification of the second embodiment, the same components as those of the second embodiment are denoted by the same reference numerals, and description thereof is omitted.

As shown in FIG. 10, the operation microscope of this embodiment is different from the second embodiment in that
The cable 24 on the side of the autofocus unit 21 and the cable 28 on the side of the laser protection shutter device 30 crawled into the storage groove 35 from 4 are guided into the storage groove 36 through the rotation axis C of the mirror holding arm 9. It is a point that was made.

The rotation axis C is fixed to the upper end of the lens holding arm 40. In addition, a slit 45 is formed in the rotation axis C along the axial direction thereof, the slit 45 opening with a width larger than the outer diameter of the cables 24 and 28. Therefore, the cables 24 and 28 can be arranged in the rotation axis C from the side through the slit 45.

The storage groove 14 and the storage groove 35 are formed in the lid 2 shown in FIGS. 9A and 9B as in the second embodiment.
The storage groove 36 is closed by the lid 38 'shown in FIG. This lid 38
'Has a derailment preventing portion 47 for preventing the cables 24 and 28 from derailing from inside the rotation axis C through the slit 45. The derailment preventing portion 47 has a concave portion 49 having a diameter substantially equal to the diameter of the rotation axis C. The lid 38 ′ is provided with connecting portions 46, 46 that are fixedly connected to the taps 48, 48 provided on the second arm 7.

In the above configuration, the autofocus unit 21 and the laser protection shutter device 30 are connected to the microscope main body 1.
1 and the auto focus unit 21
After the cable 24 on the side and the cable 28 on the side of the laser protection shutter device 30 crawl from the storage groove 14 to the storage groove 35, the cable 24 is guided into the storage groove 36 through the rotation axis C. The distal ends of the cables 24 and 28 are extended through the storage grooves 36 and connected to a power supply unit (not shown) near the gantry 1 by a connector. Thereafter, the lids 20 and 37 are placed over the storage grooves 14 and 35 and bonded and fixed. Cover from above and fix with screws.

As described above, according to the surgical microscope of this embodiment, the same effects as those of the second embodiment can be obtained, and the cables 24 and 28 are passed through the rotation axis C. Therefore, it is possible to prevent the cables 24 and 28 from being disconnected at the rotating part where the arms 7 and 9 relatively move.

By the way, the surgical microscope must be extremely clean at the time of use because of its nature of being used for surgery, but two methods have conventionally been generally used for cleaning the surgical microscope. ing.

The first method is to cover the surgical microscope with a bag from the side of the mirror before the operation, put a sterilizing gas into the bag, and move and hold the mirror. This is a method in which the mouth of the bag is tied up, the operating microscope itself is sterilized over time, and then the bag is removed from the microscope. In this method, since the coating applied to the optical components inside the microscope is eroded by the gas, it is desired that the microscope itself has a sealed structure as disclosed in Japanese Utility Model Application Laid-Open No. 6-15020.

The second method is disclosed in US Pat.
No. 1, US Pat. No. 4,561,540, US Pat.
As disclosed in Japanese Patent Application Laid-Open No. H10-163, the surgical microscope itself is covered with a sterilized plastic bag (hereinafter referred to as a drape).
In this method, the drape is fixed at the tip of the objective lens or the eyepiece with a double-sided tape or the like, and the drape is also fixed on the arm with a string or the like.

However, in the first method, when the mouth of the bag is tied on the arm, gas leaks from a gap between the cable connected to the microscope and the arm or a gap between the cable and the bag. Therefore, the sterilization effect becomes unstable, and a large amount of gas and time are required to make up for this.

In the second method, when operating the operation unit provided on the surgical microscope with the drape covered, the operation is performed from the top of the drape. There's a problem. That is, for example, in diopter adjustment of an eyepiece performed due to individual differences in human diopter, the tip of the eyepiece generally rotates at the time of diopter adjustment (see, for example, JP-A-7-146445).
Therefore, when the diopter adjustment operation part is rotated with the drape covered, the drape also rotates together, the drape is twisted and broken, and the diopter adjusted by the force that the twisted drape tries to return to the original May go crazy. Of course, in order to avoid such inconveniences, it is conceivable to fix the drape to the eyepiece below the diopter adjustment operation unit, but in this case, the unsterilized diopter adjustment operation unit If the operator is exposed outside, the diopter adjustment cannot be performed again when the operator changes.

Therefore, in the following, means for solving the problem of the first method will be disclosed with reference to FIGS. 12 to 14, and the means for solving the problem of the second method will be described. The means will be disclosed with reference to FIG.

FIG. 12 shows a first means for solving the problem of the first method. Note that, in the figure, the same reference numerals are given to portions common to FIG. In FIG. 12A, reference numeral 50 denotes a cable for the auto focus unit 21 (see FIG. 4), for example. Reference numeral 51 denotes a groove formed in the first arm 6, and the shape and size of the groove 51 are substantially the same as the cross section of the cable 50. 52 is a bag covering the surgical microscope, and 53 is a string for binding the bag 52 on the first arm 6.

FIG. 12B shows the groove 5 of the first arm 6.
FIG. 13 is a schematic cross-sectional view when a portion 1 is cut along the AA direction (see FIG. 12A). As shown, the groove 51
Is fitted with a cable 50. In this state, when the bag 52 is filled with a gas 55 having a sterilizing action, a portion of the surgical microscope contained in the bag 52 is sterilized by the gas.

According to the first means, the first arm 6
Since the gap between the cable and the cable 50 is much smaller than before, gas leakage from such a gap can be effectively and easily reduced.

Therefore, the stability of the sterilization effect can be improved. If the grooves 51 are formed in accordance with the number of cables, the greater the number of cables, the greater the effect of this means.

FIG. 13 shows a second means for solving the problem of the first method. FIG. 13A shows a cable supporting member 56. The cable support member 56 has a groove 57 having substantially the same shape and size as the cross section of the cable 50. The width X of the cable supporting member 56 is set to be the same as the width Y of the first arm 6.

To disinfect an operating microscope using such a cable support member 56, the cable support member 56 is placed on the first arm 6 as shown in FIG. The cable 50 is fitted into the groove 57. And
The first arm 6 and the cable supporting member 56 are
Fix with 3

According to such means, when the cable 50 is not provided, if the cable support member 56 which is separate from the first arm 6 is removed, gas leakage from the groove 57 can be prevented. . That is, in the first means, when the cable 50 is not provided, gas in the bag 52 may leak from the groove 51 during gas sterilization.
In the second means, since the groove 57 can be eliminated by removing the cable supporting member 56, it is possible to take a countermeasure against gas leakage according to the situation.

As shown in FIG. 14, the cable supporting member 56 is formed of an elastic member, and the opening of the groove 57 is made narrower than the diameter of the cable 50 so that the cable 50 is inserted into the groove 57.
Is installed so as to be pushed in, the gap between the cable 50 and the cable support member 56 can be eliminated.

FIG. 15 shows means for solving the problem of the second method. FIG. 15A is a sectional view of an eyepiece device 60 having a diopter adjustment mechanism. As shown, the eyepiece device 60 includes an eyepiece (eyepiece group) 61, a cylindrical lens support 63 having a helicoid 62 on the outer peripheral surface thereof, and a lens support 63 and a screw 64. A first cylindrical member 65 screwed and integrated, and an eyepiece frame 66 having an inner diameter fitted to the outer periphery of the first cylindrical member 65 and fixed to the microscope main body 11 (see FIG. 1). The eyepiece frame 66 and the screw part 67 are screwed together to be integrated, and the lens support member 6 is provided on the inner peripheral surface thereof.

, And a diopter adjustment ring 71 having an inner diameter fitted to the outer periphery of the eyepiece frame 66 and fitted outside of the eyepiece frame 66 at a position other than the distal end portion. In the figure, 7
Reference numeral 6 denotes a drape having an opening 77 at an end, and reference numeral 78 denotes a double-sided tape provided near the opening. The diopter adjustment ring 71 has a pin 70 as shown in the figure.

FIG. 15B is a view of the first cylindrical member 65 viewed from the direction of the arrow B shown in FIG.
In the drawing, reference numeral 73 denotes a notch formed in the first cylindrical member 65, and reference numeral 74 shown by a dotted line denotes an elongated hole formed in the eyepiece frame 66. The pin 70 is engaged with the notch 73 through the elongated hole 74.

The diopter adjustment in the eyepiece device 60 having the above configuration can be performed by turning the diopter correction ring 71 by hand. That is, when the diopter correction ring 71 is rotated, the pin 7
0 moves along the longitudinal direction of the elongated hole 74 provided in the eyepiece frame 66, and the pin 70 is pushed by the rotating force, so that the first cylindrical member 65 also rotates in the same direction. Therefore, the first
The lens support 63 integrated with the cylindrical member 65 also rotates. Further, in this case, since the lens support portion 63 is screwed with the second cylindrical member 68 by the helicoid 62, the rotation operation described above occurs, so that the lens support portion 63 has a lens as shown by an arrow in FIG. The linear movement (movement in the optical axis direction) of the support portion 63 is also performed at the same time. It should be noted that the drape 76 is located near the opening 77 and the eyepiece frame 6.
6 is fixed so as to be in contact with the entire circumference of the eyepiece 6, and the opening 77 is widened and narrowed so as not to be loosened with respect to the eyepiece frame 66.

Therefore, the eyepiece device 6 having the above configuration
0 indicates that the eyepiece frame 66 to which the drape 76 is fixed does not rotate during the diopter adjustment operation.
6 is not torn and torn, and the diopter adjusted by the force to return the twisted drape after diopter adjustment does not go out of order again.
