Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an accessory used for a surgical operating table, particularly a foot plate used in lumbar or spinal surgery.

[Conventional technology]

When performing surgery on the lumbar vertebrae or spine, an operating table as shown in FIG. 2 is used. That is, the back plate 30 is rotatably attached to the column 31, the leg plate 32 is pivoted to the end of the back plate 30 so that it can be bent and fixed at any position (angle), and the leg plate 32 is too
A foot plate 1 is pivotally mounted so that it can be bent and fixed at an angle of 90 degrees or more.

FIG. 2 shows the body position taken when performing surgery on the lumbar vertebrae or spine using the foot plate 1. Patient P's body bends at the waist and knees to form a Z shape. The body weight is supported by the chest mat 33, prone position mat 34, leg plate 32, foot plate 1, etc. In particular, the lumbar region is supported by lateral supports 35 on both sides of the pelvis and hip supports 36 at the rear to prevent pressure on the abdomen.
This illustrated position is particularly popular because there is no pressure on the abdomen and therefore there is very little bleeding. The foot plate 1 used at this time is required to be easily attachable and detachable.

Conventionally, such a foot plate is shown in FIG. 3. In this figure, 1 is the front view of the foot plate, 2
3 is a back view, and 3 is a side view. This foot plate is composed of a clamp part 41 that is attached to the operating table, and a foot plate plate 42 (covered with a flexible mat 43) on which the foot is placed.Furthermore, the ferrule 45 and the ferrule 46 can be freely adjusted by a clamp lever 44. In other words, the foot plate 42 can be bent and fixed at any angle as shown by the two-dot chain line.

[Problem that the invention attempts to solve]

In the conventional foot board as shown in FIG.
are hung horizontally in parallel. Therefore, there is a problem that the overall shape of the foot plate becomes large and heavy. This horizontally suspended stay 49 is not necessarily necessary for the surgical operation, but if it is not present, the stay 49 will be more weighed and easier to attach and detach. The function of a footboard as a footstool is not just to support the foot; other factors that are unrelated to its original function, such as shape, feel when holding it, ease of handling, and weight, are also important factors. These incidental functions are treated poorly.

This idea was devised in view of the problems mentioned above, and its purpose was to eliminate as much as possible the overhang of the stays, etc., to reduce the weight, and to improve the feel when holding it, making it easier to handle. The purpose is to provide a board.

[Means for solving problems]

That is, in order to solve the above-mentioned problems, this invention aims to provide a foot plate for an operating table with a connecting shaft that passes through both sides of a frame fixed to the foot plate and serves as a supporting axis of the foot plate, and a connecting shaft that passes through both sides of a frame fixed to the foot plate. A fitting that is inserted into both ends of the shaft and used to install the connecting shaft on the operating table, a female threaded metal fitting that is inserted into the vicinity of the inner end of the connecting shaft, and a fitting that is inserted into the notch provided in the connecting shaft and is inserted into the connecting shaft. A pin that integrates the female threaded fitting and the connecting shaft; a ferrule that is matably fixed to the frame, the connecting shaft, and one of the fittings, respectively; and a ferrule that is screwed into the female threaded fitting from the outside of the fitting. and a tightening screw, the ferrules being engaged and separated by the tightening screw.

[Effect]

When the tightening screws are loosened, the foot plate and frame can be freely rotated around the connecting axis. Then, when the foot plate is set at a predetermined angle with respect to the operating table and the tightening screw is tightened again, the ferrule fixed to the frame and the ferrule fixed to the connecting shaft engage, and the foot plate and frame are fixed at that angle. By further tightening the tightening screw, the connecting shaft can be slid in the axial direction.

〔Example〕

Hereinafter, specific embodiments of this invention will be described with reference to the drawings.

FIG. 1 is a cross-sectional view of a foot plate 1 for an operating table according to this invention taken along the line X--X in a state where the foot plate is rotated as shown by the two-dot chain line in FIG.
Further, FIG. 2 is an enlarged detailed view of the W section of 1. In these figures, reference numeral 2 denotes a foot plate, and a flexible mat 3 is stretched over the upper surface. A frame 4 is fixed to the other surface of the foot plate 2. Reference numeral 5 denotes a connecting shaft which is passed through holes bored on both sides of the frame 4 so that it can be moved left and right to some extent. The frame 4 has a ferrule 6
However, a ferrule 7 is fixed to the connecting shaft 5 by welding or the like, and these ferrules 6 and 7 are designed to mesh with each other.

Further, fittings 8 and 9 for attaching to the accessory rails (described later) of the leg plate frame are fitted into both ends of the connecting shaft 5, and the fittings 9 are fixed with pins 10. The ferrule 7 is also welded. 12 and 13
2 is a leg plate (corresponding to 32 in FIG. 2), and flexible mats 14 and 15 are stretched on the upper surface thereof, respectively. Leg plate frames 18 and 19 to which accessory rails 16 and 17 are fixed are fixed to the leg plates 12 and 13, respectively, and the mounting tools 8 and 9 are attached to the accessory rails 16 and 17 by mounting screws 20 and 21. It is becoming more and more popular.

Next, the connecting shaft 5 is provided with a notch 22, and a female threaded metal fitting 23 is fitted inside the connecting shaft 5, and the female threaded metal fitting 23 protrudes outside the notch 22. A dowel pin 11 is inserted therethrough. A tightening screw 24 is screwed into the female threaded metal fitting 23 from the outside of the fitting 8.
In this way, by turning the tightening screw 24, the female threaded metal fitting 23 can be moved left and right within the range of the notch 22, and the tightening force by the tightening screw 24 is transmitted to the outside of the connecting shaft 5. Therefore, the tightening screw 24
When tightened, the ferrule 6 and ferrule 7
The fittings 8 and the foot plate 2 are fixed and their angles are maintained. When changing the angle of the foot plate, it is sufficient to loosen the tightening screw 24, disengage the ferrules 6 and 7, change the angle of the foot plate 2 to the desired angle, and then tighten the tightening screw 24 again.

The details of this invention are as above, but the foot plate according to this invention can be used not only as an accessory foot plate for an operating table, but also for various devices, and can be used effectively by adjusting the angle and fixing it. It is possible.

[Effect of idea]

Since the operating table accessory foot plate according to this invention has the structure described in detail above, there is no need for extra overhangs such as stays around the connecting axis, that is, the joint axis, making it easy to attach and remove. It becomes easier. In addition, the weight is reduced, the external shape, the feel when holding, the ease of handling, etc. are improved, and the functionality as an operating table is increased, even if it is inconvenient, thereby making it possible to provide an excellent foot plate.
