Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a surgical microscope, and more specifically, a surgical microscope having a light source unit having a light source for illumination in a lamp house. About.

(Prior Art) Conventionally, a light source shown in FIG. 4 has been known as a light source unit having a light source for emitting light for illumination.

The light source unit 30 shown in FIG.
And illumination light is radiated to the eye E, which is an operation target, via the objective lens 22.

The light source unit 30 is disposed at a predetermined angle with respect to the box-shaped lamp house 31, a light source 33 such as a halogen lamp mounted in the lamp house 31 by a support 32, and the light source 33 in the lamp house 31. A prism 34 for reflecting light from the light source 33 and irradiating the light as illumination light toward the objective lens 22 is provided.

However, since the light source unit 30 is configured to remove the heat generated by the light source 33 by natural convection, the heat generation countermeasures are insufficient, such as the temperature of the lamp house 31 itself rises so much as to burn when touched.

In the past, attempts have been made to forcibly cool the lamp house 31 by installing a cooling fan in order to solve the above-mentioned disadvantages of the light source section 30.

However, in this case, there is a problem that the microscope main body 20 vibrates and the observation target becomes difficult to see due to the influence of the vibration by the fan motor. There was a problem of giving. Further, when a sterilization cover is attached to the microscope main body 20 for sterilization during the operation, there is a problem that heat is trapped in the sterilization cover and there is no point in attaching a cooling fan.

(Problem to be Solved by the Invention) The present invention has been made in view of the above circumstances, and has an operation having a light source unit that can maintain a light source unit at an appropriate temperature and does not generate vibration in the light source unit. It is an object to provide a microscope for use.

[Means for Solving the Problems] The present invention relates to a surgical microscope having a light source unit provided with a light source for illumination in a microscope main body, the surgical microscope being separated from the microscope main body and communicating with the light source unit. A light source cooling device comprising a cooling means and a control means for controlling a cooling operation of the cooling means.

(Operation) The operation of the device having the above configuration will be described below.

According to this device, since the control unit controls the cooling operation of the cooling unit, the light source unit is cooled.

In addition, since the cooling unit is configured to be separated from the microscope main body and communicate with the light source unit, the vibration of the cooling unit is not directly transmitted to the light source unit.

(Embodiment) An embodiment of the present invention will be described below with reference to FIG.

FIG. 1 shows a light source cooling device incorporated in a surgical microscope according to the present invention. This light source cooling device 1 is provided with a cooling means 3 attached to a light source unit 2 having the same configuration as that of the conventional example and performing a forced cooling operation. A temperature sensor 5 as detection means mounted in a box-shaped lamp house 4 constituting the light source unit 2; a cooling operation of the cooling means 3 which is connected to the temperature sensor 5 based on an output signal of the temperature sensor 5; And control means 6 for controlling

The light source unit 2 includes a light source 33 such as a halogen lamp supported by a support 32 and a reflection mirror 34 as in the conventional example, and irradiates illumination light to the outside.

The cooling means 3 includes an air pump 7 disposed separately from the lamp house 4, an exhaust pipe 8 having one end connected to the air pump 7 and having the other end near the light source 33 of the lamp house 4, and one end open. In this state, the air conditioner includes an intake pipe 9 having the other end facing the lamp house 4 and an exhaust port 11. By the suction operation of the air pump 7, air outside the lamp house 4 is guided into the lamp house 4 through the suction pipe 9, and the air in the lamp house 4 is sucked through the exhaust pipe 8 to exhaust the air through the exhaust port 11. The air pump 7 and the lamp house 4 are connected to each other by forming a flow path of air discharged from the air pump 7.

According to the light source cooling device 1 having the above-described configuration, the heat accompanying the light emitting operation of the light source 33 is cooled by the forced cooling operation by the air pump 7, and at this time, the temperature inside the lamp house 4 becomes lower than the temperature. The temperature is detected by the sensor 5 and the control means 6 controls the suction air volume of the air pump 7 based on the detection result, so that the temperature inside the lamp house 4 is always maintained at an appropriate value.

In addition, since the air pump 7 and the lamp house 4 are arranged separately and communicate with each other by the exhaust pipe 8, the vibration of the air pump 7 does not directly transmit to the lamp house 4 and the lamp house 4 itself vibrates. Is gone.

FIG. 2 shows the light source unit 2 as a microscope main body of an operating microscope 15.
20 shows an example in which the cooling means 3 is attached to the light source 2.

FIG. 3 shows an example in which the cooling means 3 is attached to a microscope main body 20A having a configuration slightly different from that of the microscope main body 20.

The microscope body 20A is provided with a lamp house on the side wall of the lens barrel 20b.
The exhaust pipe 8 and the intake pipe 9 communicating with the cooling means 3 are attached to the lamp 4a.

In the lamp house 4a, a light source 33 is fixed by a support 32a, and a condenser lens 35 is further disposed. In any of the above embodiments, the air pump 7 serving as a cooling means
Is arranged separately from the microscope main body 20 or 20A.

Further, a projection lens 36 and a prism 34 are disposed above the objective lens 22 in the lens barrel 20b.

2 and 3, when the sterilization cover 16 is attached to the microscope main body 20 for sterilization during surgery, each of the exhaust pipe 8 and the suction pipe 9 is inserted through the sterilization cover 16. Holes are provided, and the two pipes 8 and 9 are inserted through the respective insertion holes, so that the forced cooling operation by the air pump 7 can be performed without any trouble.
No heat is trapped in the lamp house 4 or 4a covered by 16, and the temperature of the microscope body 20 or 20A does not rise.

Further, since the air pump 7 is disposed separately from the lamp house 4 or 4a provided in the microscope main body 20 or 20A, the lamp house 4 or 4a and the microscope main body 20 or 20A may be affected by the vibration of the air pump 7. Absent. For this reason, it is possible to solve the problems that the observation target becomes difficult to see due to the vibration and that the movement of the air near the operation site due to the vibration causes pain to the patient.

The present invention can be variously modified in addition to the embodiments described above.

[Effects of the Invention] According to the present invention described in detail above, with the above configuration, the light source unit is always cooled by the cooling operation of the cooling unit based on the control of the control unit, and the influence of the vibration of the cooling unit is also avoided. It is possible to provide a surgical microscope having a light source unit that can be used.
