Description

  The present invention relates to a surgical microscope apparatus used by being covered with a drape.

  A surgical microscope apparatus used in neurosurgery or the like supports a surgical microscope in a state of being suspended in the air. A parallel link mechanism extending in the vertical direction is pivotally supported on the stand body installed on the floor, a horizontal arm extending in the horizontal direction from the upper end of the parallel link mechanism is formed, and a surgical microscope is suspended from the distal end side of the horizontal arm. To support.

  The surgical microscope apparatus is covered with a drape to make at least the surgical microscope and the lateral arm sterile. When the drape hangs down, the view of the doctor or assistant is hindered, and therefore, the air in the drape is sucked by the exhaust pump means built in the horizontal arm to bring the drape into close contact with the surgical microscope apparatus (see, for example, Patent Document 1).

Japanese Patent No. 2898980

  However, in such a related technique, since the exhaust pump means is built in the side arm in advance, maintenance work such as repair and maintenance of the exhaust pump means is troublesome. In addition, since the weight of the horizontal arm increases by the amount of the built-in exhaust pump means, the counterweight for balancing the overall weight is also increased.

  According to the present invention, it is possible to provide a surgical microscope apparatus in which maintenance work of the exhaust pump means is easy and the lateral arm is lightened.

  According to the first aspect of the present invention, the vertical arm is attached to the floor body of the stand main body so as to be tiltable back and forth around the shaft support portion set at the middle position thereof, from the shaft support portion at the upper end of the vertical arm. A surgical microscope apparatus which extends a lateral arm and supports a surgical microscope on the distal end side of the lateral arm, and at least the surgical microscope and the lateral arm are covered with a drape. The lateral arm has a hollow structure, and the distal end of the lateral arm A suction port is formed on the side and a connection port is formed on the base end, and only the part straddling each shaft support from the stand body to the connection port of the horizontal arm is exposed to the outside, and the rest are inside the stand body and the vertical arm. An existing intake pipe is piped, and a terminal of the intake pipe is structured to be connectable to an exhaust pump means installed outside the stand body.

  According to the second aspect of the present invention, the intake pipe is extendable and contractible in the longitudinal direction.

  According to the third aspect of the present invention, the terminal of the intake pipe is present on the outer surface of the stand body as an intake connection portion connectable to the exhaust pump means.

  According to the first aspect of the present invention, the stand main body and the side arm have only an intake pipe, and the exhaust pump means is placed outside the stand main body, so that maintenance work such as repair and maintenance is easy. Moreover, since only a part of the intake pipe exists in the horizontal arm, the weight of the horizontal arm does not increase.

  According to the second aspect, since the intake pipe is extendable in the longitudinal direction, it is possible to follow the movement of the vertical arm and the horizontal arm.

  According to the third aspect, since the terminal of the intake pipe is present on the outer surface of the stand body as an intake connection portion connectable to the exhaust pump means, the exhaust pump means is removed from the stand body when unnecessary. This is convenient for transporting the stand body.

The side view which shows the surgical microscope apparatus which concerns on embodiment of this invention. The perspective view which shows the front-end | tip vicinity of a horizontal arm.

  A preferred embodiment of the present invention will be described with reference to FIGS.

  The stand main body 1 is for hanging the surgical microscope 2 in the operating room. A vertical link mechanism A including a vertical arm 3 and a sub arm 4 is supported on the stand body 1 so as to be tiltable back and forth around a shaft support portion 5 set in the middle of the vertical arm 3.

  A counterweight W is provided below the parallel link mechanism A. A lateral arm 6 extends forward from the upper part of the parallel link mechanism A. The lower end of the distal arm 7 is pivotally supported at the distal end of the lateral arm 6, and the surgical microscope 2 is supported below the suspended arm 8 via the suspension arm 8.

  The lower end of the base end arm 10 is pivotally supported on the shaft support portion 9 of the vertical arm 3 with respect to the horizontal arm 6. The proximal arm 10 is always kept vertical by another parallel link mechanism (not shown) in the vertical arm 3. The upper ends of the proximal arm 10 and the distal arm 7 are connected by a sub arm 11. As a result, the vertical state of the distal arm 7 is maintained even when the horizontal arm 6 is rotated up and down around the shaft support 9.

  The horizontal arm 6 has a cylindrical shape made of metal and is convexly curved upward. The reason for bending upward is to secure a lower working space. Both ends of the horizontal arm 6 are formed by hollow members 12 and 13 made of casting. The horizontal arm 6 is hollow as a whole, including the hollow members 12 and 13 as a structure. The rear part of the hollow member 12 from the vertical arm 3 constitutes a part of the parallel link mechanism A, and the horizontal arm 6 is interlocked with the parallel link mechanism A.

  An air inlet 14 is formed in the hollow member 13 at the tip of the horizontal arm 6. A connection port 16 is formed in the rear hollow member 12.

  A necessary part including the lateral arm 6 from the surgical microscope 2 is covered with a drape P for making the stand main body 1 sterile. In particular, when the drape P covering the horizontal arm 6 and the surgical microscope 2 hangs down, the visual field of the doctor, assistant, or the like is obstructed, so the drape P needs to be in close contact with the horizontal arm 6 or the surgical microscope 2.

  Therefore, the air E in the drape P is sucked from the air inlet 14 at the tip using the horizontal arm 6 having a hollow structure as a ventilation path. The suction is performed by the exhaust pump means 15.

  An intake pipe 17 is piped from the stand body 1 through the vertical arm 3 to the base end of the horizontal arm 6. The intake pipe 17 basically passes through the inside and is exposed to the outside so as to straddle only the shaft support portions 5 and 9. In the vertical arm 3, circular holes 18 and 19 are formed in the vicinity of the upper shaft support portion 9 and in the vicinity of the lower shaft support portion 5. A circular hole 20 is formed in the stand body 1 in the vicinity of the shaft support portion 5. The intake pipe 17 is exposed between the connection port 16 and the circular hole 18 between the vertical arm 3 and the horizontal arm 6, and the intake pipe is connected between the circular hole 19 and the circular hole 20 between the vertical arm 3 and the stand body 1. 17 is exposed.

  The intake pipe 17 is a resin pipe that has rigidity in the cross-sectional direction and does not collapse, but has stretchability in the longitudinal direction. Therefore, the movement of the horizontal arm 6 and the vertical arm 3 can be followed.

  The terminal of the intake pipe 17 exists on the outer surface of the lower part of the stand body 1 as the intake connection portion 21. An exhaust pump means 15 installed on the floor can be connected to the intake connection portion 21 when necessary. This exhaust pump means 15 is convenient because it can be removed from the intake connection portion 21 when it is not needed during transportation.

  When the switch of the exhaust pump means 15 is pressed, the inside of the horizontal arm 6 is depressurized via the intake pipe 17, the air E in the drape P is sucked from the intake port 14 at the tip, and the sucked air E is sucked into the intake pipe 17. And exhausted through the exhaust pump means 15.

  Since air E is sucked from the air inlet 14 at the tip of the horizontal arm 6, the drape P near the surgical microscope 2 and near the tip of the horizontal arm 6 is surely sucked and brought into a close contact state, obstructing the visual field of the person around. do not do.

  Since the exhaust pump means 15 is installed outside the stand main body 1, when the exhaust pump means 15 is repaired or maintained, the exhaust pump means 15 can be removed and the work can be easily performed.

  Further, since the exhaust pump means 15 itself does not exist inside the horizontal arm 6 as in the prior art, the overall weight balance of the stand body 1 by the counterweight W is not affected.

  In the above embodiment, one continuous intake pipe 17 is taken as an example, but a structure in which a plurality of intake pipes are connected may be used.
