Description

The present invention relates to a drape for a surgical microscope.

[Conventional technology]

The method of using a drape to put it on a surgical microscope and make the outside of the drape sterile is already widespread, but as a fixing method after the drape is attached, the drape is bundled with rubber or a string, and a microscope support arm or the like is used. It is usual to fix to.

[Problems to be Solved by the Invention] By the way, in such a conventional fixing method, portions other than the drape portion bundled with rubber, a string, or the like are loosened or swelled by lamp heat or the like. Moving the mirror or arm left the drape inflated, hindering the surgeon's field of view. In addition, if the swelling is inflated, the scalpel or the like may be incised by touching the scalpel, making it impossible to make the germ sterile, which may even be dangerous for the patient. Further, if a string is fixed in several places in order to remove slack of the drape or the like, not only is it troublesome but also the operability may be impaired.

In view of the above problems, an object of the present invention is to provide a drape for a surgical microscope, which can be brought into close contact with a mirror or an arm when mounted.

[Means and actions for solving the problem]

In order to achieve the above object, the surgical microscope drape according to the present invention is provided with at least one air outlet for discharging air inside the drape to the outside. During the operation, the drape is brought into close contact with the mirror body and the arm by activating the exhaust means connected to the air outlet.

〔Example〕

Hereinafter, the present invention will be described in detail based on illustrated embodiments.

FIG. 1 is a first view of a drape for an operating microscope according to the present invention.
FIG. 2 is a plan view of the embodiment, and FIG. 2 is a side view showing a state where the first embodiment is attached to a surgical microscope.

In FIG. 1, 1 is a bag-shaped drape made of an extremely thin and flexible transparent sheet, 2 is a joining edge of the front and back sheets, 3 is an open end, 4 is an eyepiece mounting portion, and 5 is a sideoscope. Mounting parts 6 and 7 used when a camera or TV camera is mounted on the mirror body can be easily removed by pulling each end of the eyepiece mounting part 4 and the accessory mounting part 5, respectively. A perforation for enabling, 8 is an elastic objective lens cap, 9 is a transparent plastic plate removably fitted to the objective lens cap 8, and 10 is an air outlet connected to an air suction device described later. , 11, 12 and 13 are an open end 3, an eyepiece mounting part 4 and an accessory mounting part 5, respectively.
Are used to make the open end 3, the eyepiece mounting portion 4 and the accessory mounting portion 5 close to the arm, eyepiece tube and accessories of the operating microscope, respectively.

Next, the operation of the first embodiment will be described. First, before describing the operation, a method of attaching the drape 1 to the surgical microscope will be described with reference to FIG. In the drawing, reference numeral 14 denotes a gantry of the operating microscope, 15 denotes a light source arm mounted on the gantry 14 so as to be rotatable horizontally, 16 denotes a mirror support arm mounted on the light source arm 15 so as to be vertically movable and horizontally rotatable, Is an arm
The mirror is supported by 16.

The drape 1 has a portion extending from the lens body portion 17 to the light source arm 15 via the lens body support arm 16 with the opening end 3 expanded, and the eyepiece mounting portions 4, 4 are respectively attached to the eyepiece tube. And the end is tied and fixed with a string 12 and then the tip 4 '
This is cut off at the position of perforation 6 by pulling, and then the objective lens cap 8 is fitted to the objective lens,
Finally, the opening end 3 is tied to the light source arm 15 using the string 11 to keep the outside aseptic. In this case, the accessory attachment parts 5, 5 are folded and drape 1 with tape or the like.
However, when used, it is handled in the same manner as the eyepiece mounting portion 4. Next, the air outlet 10 of the drape 1 is connected to an air suction device 19 via a suction pipe 18. Thus, when the air suction device 19 is operated in this state, the air in the drape 1 is discharged to the outside. Since the inside of the drape 1 is substantially airtight, when the air is exhausted as described above, the internal pressure decreases, and as a result, the drape 1 is deflated and comes into close contact with the mirror body and the arm. Therefore, the visual field is hardly obstructed by the drape 1 and the operability is not impaired because only the end of the drape 1 is fixed to the surgical microscope.

If the drape 1 has a high degree of closeness, the operability may be slightly impaired. In such a case, the output of the air suction device 19 is adjusted to adjust the amount of the drape 1 to optimize the operability. Can be kept in condition.

FIG. 3 is a perspective view of the second embodiment, and FIG. 4 is a side view showing a state in which the second embodiment is attached to a surgical microscope.

This embodiment does not use the cords 11, 12, and 13 as in the first embodiment, and as shown in FIG. 3, of course, the vicinity of each of the open end 3, the eyepiece mounting portion 4, and the accessory mounting portion 5. The annular rubber 20 is also fixed to the middle part, as shown in FIG.
The ring-shaped rubber 20 is fixed to each part of the operating microscope, and is kept airtight. Then, similarly to the first embodiment, the air outlet 10 is connected to the air suction device 19 via the suction pipe 18 and the air suction device 19 is operated, whereby the drape 1 is deflated and the mirror body and the arm portion are depressed. To be close to.

Therefore, in the case of the present embodiment, since the annular rubber 20 is used for fixing the drape 1, the trouble of tying with a string is expended, and the operability of the surgical microscope is impaired unlike the case of the string due to the elasticity of the rubber 20. There is also the advantage that it is not.

FIG. 5 is a plan view of the third embodiment, which is branched, and each end of the branch portion is a joining edge at a substantially central portion of the eyepiece mounting portion 4, the accessory mounting portion 5, and the drape 1. An intake pipe 21 extending close to 2 and having a distal end protruding from the open end 3 is adhered to the inner surface of the drape 1. The tip of is an air outlet 10.

Therefore, if the present embodiment is attached to an operating microscope, and the air outlet 10 is connected to the air suction device 19 via the suction pipe 18 to operate the air suction device 19 as in the first embodiment, The eyepiece mounting portion 4 and the accessory mounting portion 5 can be fixed to the eyepiece tube and the accessory, respectively, and can be kept in an airtight state without using rubber or a string. Become close to the department. However, the opening end 3 is fixed to the light source arm using a string 11 or a ring rubber, and the eyepiece mounting part 4 and the accessory mounting part 5 are also fixed with a ring rubber or the like when their respective tips are removed. It must be kept airtight.

FIG. 6 is a plan view of the fourth embodiment, in which each one end extends near the joint edge 2 substantially at the center of the eyepiece mounting part 4, the accessory mounting part 5, and the drape 1 and the other end. A plurality of intake pipes 23 whose parts protrude from the open end 3 are bonded to the inner surface of the drape 1, and each one end serves as an intake port 24 and each other end serves as an air discharge port 10. I have.

Therefore, this embodiment was attached to the surgical microscope, and each outlet
By connecting each of the air suction units 10 to each of the air suction units 19 and operating them, the same effect as in the third embodiment can be obtained, and by changing the output of each air suction unit 19, the suction of each part of the drape 1 can be achieved. By changing the force, for example, in the moving part such as the rotating part of the surgical microscope, adjust the suction force so as not to hinder the movement,
In other parts, it is possible to increase the suction power.

FIG. 7 is a plan view of the fifth embodiment, in which the drape 1 is constructed by joining the edges of three transparent sheets, and two of them are entirely formed while leaving a branch-like pattern. By adhering, an intake path 25 corresponding to the intake pipe 21 of the third embodiment is formed, and each tip of the branch portion becomes the intake port 26 and the tip of the trunk portion becomes the air exhaust port 10. I have.

Therefore, this embodiment was attached to the surgical microscope and the outlet 10
Is connected to the air suction device 19 and operated to obtain the same effect as in the third embodiment. In addition, the present embodiment can be manufactured using only three transparent sheets and does not need to use a tube or the like.

〔The invention's effect〕

As described above, the drape for an operating microscope according to the present invention has an important practical advantage that it can be brought into close contact with the mirror body and the arm when mounted.
