JPH0648644U - Operating table - Google Patents

Abstract

(57) [Summary] [Purpose] When preparing for surgery, the position of the affected area of the patient should be appropriately and promptly optimized, and there is no need to adjust the positional relationship of other equipment elements. [Structure] The movable table top part is slid horizontally along the floor in the front, rear, left and right directions.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of an operating table, particularly an operating table such as an operating table for brain surgery, which requires highly accurate positioning of an affected area.

[0002]

[Background of device]

 Conventionally, during surgery, particularly in brain surgery, surgery is performed so that the patient on the operating table can change the posture by refracting or tilting the seat floor plate, position the most suitable for the work, and face the affected area. The table is movable. Then, if necessary, optical elements such as lenses and mirrors are used to more accurately capture the affected area.

As described above, it is necessary to adjust the position of the patient with respect to various instruments and devices in order to perform the optimal positioning for the surgery. At that time, the operating table itself is moved. Since this has an effect on the fundamental stability, it is desirable to move the patient's position while the operating table itself is fixed.

[0004]

[Problems to be solved by the device]

 Therefore, conventionally, a mechanism for sliding the seat floor plate on which the patient is placed has been developed.However, according to this conventional mechanism, the slide is performed along the seat floor plate, and it is already in an inclined state. Slides not only in the horizontal direction but also in the vertical direction, that is, at an angle that is inclined with respect to the floor surface, which causes separation and contact with the above-mentioned optical system and the like. There was the trouble of having to adjust the position of the body etc., which meant that time wasted in preparation for the surgery.

[0005]

[The purpose of the device]

 Therefore, the present invention has been made by paying attention to the problems of the above-mentioned conventional techniques. By solving these problems, the position of the patient can be accurately moved back and forth, left and right with respect to the floor surface, and proper positioning can be performed. It is an object of the present invention to provide an operating table that can be quickly operated and does not require position adjustment of the attached optical system and the like.

[0006]

[Means for Solving the Problems]

 In order to achieve this object, the operating table according to the present invention is characterized in that a movable table top part is horizontally slid along the floor surface in the front, rear, left and right directions.

[0007]

[Action]

 With the above-mentioned configuration, the patient can be repositioned and positioned accurately only in the horizontal direction, and the troublesome positional adjustment of auxiliary instruments and devices is completely eliminated, so that the surgery can be started and executed quickly. It will be possible.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing an essential part of an operating table embodying the present invention, FIG. 2 is a side view thereof, and a nest 3 is a front view thereof.

In these figures, reference numeral 1 denotes a chassis of an operating table, and the chassis 1 has a rectangular shape. A support portion 2 is provided at an outer end of the chassis 1 in the lateral direction, and a support portion 3 to which a table top is attached is attached to a base surface thereof.

The support portion 3 is provided with a pair of laterally (Y-axis direction) guide rails 4, 4, and sliders 5, 5, ... Are laid on the guide rails 4, 4. . A frame-shaped frame 6 is provided on the sliders 5, 5, ... With a bottom step portion fitted between the upper surface step portions of the sliders 5, 5 ,.

Support bars 7 having an L-shaped cross section are provided on both upper and lower edges of the frame 6 in the front-rear direction (X-axis direction), and one end of the support bar 7 is extended. It is connected to the horizontal cylinder 8.

Further, on the inner surface of the frame 6 in the front-rear direction, there are hooked bodies 8 formed on the outer side, and the upper and outer surfaces of the hooked bodies 20 20 are formed on the inner surface of the support bar 7 7. A movable body 9 is provided in sliding contact with the. The movable body 9 has a substantially U-shaped cross section, and its upper end projects from the support portion 3 to form an assembly portion 10 with the lower surface of the table top. Further, a support pillar 11 is provided on one outer side surface of the movable body 9, and a front-rear direction cylinder 12 is connected to the support pillar 11. The front-rear cylinder 12 is also attached to the frame 6 at its rear end so that it can be slid laterally.

On the other hand, 13 is a pressure oil tank and 14 is a motor pump, which is also mounted on the drive and control system of the slide mechanism on the chassis 1. Further, 15 is a battery, 16 is a transformer unit, 17.17 is a relay, 18.18 is a non-leak solenoid valve group, and 19 is an electric component unit. The cylinders 8 or 12 are operated by these systems.

The main part of the operating table according to the present embodiment is configured as described above. When the cylinder 8 is driven, the support part 3 slides laterally as a whole along the guide rails 4 and 4 and when the cylinder 12 is driven, the movable body 9 slides in the front-rear direction. The table top attached to the assembling part 10 of 9 can freely slide forward, backward, leftward and rightward along the floor surface, that is, horizontally.

Further, in the present embodiment, a hydraulic system mechanism is used to slide the table top on the operating table to the front, rear, left and right, but in addition to this, a mechanism using gears and clutches, electromagnetic waves and superconductivity. It is also possible to achieve the purpose by substituting the means using air, etc.

[0016]

[Effect of device]

 The operating table according to the present invention is constructed and operates as described above. By sliding the patient, especially the affected area, horizontally and anteroposteriorly, there is no need to adjust other equipment elements, and the affected area can be smoothly positioned to the optimum position, so that surgery can be performed quickly. It can be done.
