Description

[Detailed description of the invention] [Industrial application field] This invention relates to a treatment table, and more specifically, to a treatment table in which the refraction angle of the divided floor plate on which the patient is placed can be adjusted steplessly in a hook-type manner. It is.

[Prior Art] A treatment table used for performing surgical treatment is designed such that the chair or table is tilted or bent in order to facilitate treatment for a patient.

This tilting and bending operation is often done manually by turning or moving a handle installed on the side of the chair or treatment table, using screw rods, pairs, or levers, and recent ones use a motor or fluid pressure. There is something I used.

[Problems that the invention aims to solve] However, the former, which uses screw rods, pairs, and levers, does not require power equipment, but requires gears and link mechanisms to transmit the movement of turning and moving the handle. In the latter case, power equipment is required to operate the motor and compressor for producing the fluid, and both require a high initial investment amount. The disadvantage is that the location is limited.

The purpose of this invention is to eliminate the above-mentioned drawbacks and to provide a treatment table with a simple structure and low cost without sacrificing operability by applying the principle of the swivel hook.

[Means for Solving the Problems] The above purpose is to provide a head floor plate 23 which is individually pivoted via hinge connecting parts 26, 26 to one end of the upper part of the underframe 1 on which the legs 12 to 15 are protruded downward. The trunk floor plate 22 and the hinge connection part 2 are attached to the trunk floor plate 22.

and 342c by _individually operating the handle rods 35a, 35b and 35c to individually change the angles of the pair of locking plates 34a, 34b and 34c against the gravity, respectively. By aligning each axis _l1 of the support rods 37a, 37b, and 37c forming the pair with the center line _l2 for each pair, the support rods 37 forming the pair are aligned.
This is achieved by varying the protruding lengths of the plates a, 37b and 37c for each pair, and individually varying the angle of inclination and refraction of the floor plates 21, 22 and 23.

[Function] The treatment table of this invention is divided into a plurality of parts according to the treatment area of the patient, and is refractably connected via a hinge, and one of the connecting parts is attached to the end of the table frame to prevent the bending of the two floor plates. The center of the support rod insertion hole drilled in the locking plate that is rotatably attached to the support shaft with the handle rod on each floor plate that has been pivoted without any problem is aligned with the axis of the support rod that is pivoted on the floor plate. By doing so, the support rod passes through the hole, so by bending the floor plate at the hinge joint and holding the handle rod, change the axis of the support rod and the center of the support rod insertion hole to fit both sides of the hole. It can be gripped and fixed in a swivel hook type by the force applied to two points on the edge, and by keeping the bent state, each floorboard can be easily bent.

[Example] The treatment table of this invention has a table frame 1 as shown in Fig. 1.
It is composed of a floor assembly 2 and a bending operation mechanism 3.

As shown in FIGS. 1 and 2, the underframe 1 is constructed by attaching legs 12 to 15 to the four corners of a rectangular frame material 11 and reinforcing material 1.
The legs are reinforced at 6 and 17, and the edge at one end of the frame member 11 is cut diagonally to form an inclined surface 18. As shown in FIGS. 1 to 3, the assembled floorboard 2 has a trapezoidal shape with a leg floorboard 21 covering approximately 2/3 of the underframe 1 and a body floorboard 22 covering approximately 1/3 of the underframe 1. Head floor plate 23 with an oval hole 24 in the
The hinge connecting portions 25 and 26 are provided, which are bendably connected through a hinge. Here, the head floor plate 23 and the body floor plate 22 are pivotally connected to the upper part of the underframe 1 through hinge connection parts 26, 26, respectively, and the leg floor plate 21 is connected to the end of the body part floor plate 22 by a hinge connection part 25.
Establish a central location.

The bending operation mechanism 3 is connected to the leg 1 as shown in FIG.
2 and 13 and between the frame members 111 and 112, and a sleeve 341 provided at one end of this support shaft. A pair of locking plates 34a, 34b are integrated by attaching handle bars 35a, 35b, 35c that are slightly bent in the same direction and have a grip ball 351 attached to the end.
34c, one end is attached to each of the floor plates 21 to 23 with a pivot member 36 so as to be able to swing in the length direction of the floor plate, and each pair of locking plates 34a,
Support rod insertion holes 342 opened in 34b and 34c
It is composed of support rods 37a, 37b, and 37c with a slightly smaller diameter and shorter than the leg length, which can be fitted transparently into the locking plates 34a to 34c and the support rods 37a to 37c, which are hardened by quenching.

As shown in FIGS. 1 to 3, the overall configuration is such that the assembled floorboards 2 are bently connected via hinge connection parts 25 and 26, and the inclination of the head floorboard 23 is adjusted via the hinge connection part 26. Relief slope 1 that allows

Support rods 37a to 37c, which are swingably attached at one end with a pivot member 36 to 23, are locked in a horizontal state when each support rod is in a vertical state with respect to each floor plate 21 to 23 in a horizontal state. The support rod insertion holes 3 are related so that the center axes of the support rod insertion holes 342a to 342c formed in the plates 34a to 34c are aligned with the center axes of the support rods 37a to 37c.

The treatment table of this invention is constructed as described above, and Figure 1 shows the head floor plate 23 on which the patient's head rests.

In the case of FIG. 1, the head floor plate 23 is pulled out to near the tip farthest from the pivot joint, and in the case of FIG. By pushing down in the case of FIG. 1 and lifting up in the case of FIG. 4, the axis of the support rod 37a and the center line of the support rod insertion hole 342a of the locking plate 34a are supported as shown in FIG. Center line _l1 of rods 37a to 37c and each insertion hole 342a
The center line _l2 of ~342c is the hole 342a~34.
By making it possible to intersect at the center of 2c,
According to the principle of a free hook, contact points a and b are created by a force w applied in a direction perpendicular to the floor surface at a position away from the above-mentioned intersection c.
In this case, forces +Fa and -Fb are applied in opposite directions, and a force w' in the opposite direction to the force w is applied to the intersection c, but since each support point of the locking plates 34a to 34c does not move, the locking The stop plates 34a to 34c do not rotate and maintain this state, and can be safely fixed in a swivel hook type as long as no slipping occurs at the contacts a and b.

5 and 6 show that in order to lift the patient's head and lower back, the torso floor plate 22 is further lifted on the hinge connection part 25 side in the state shown in FIG. This state can be formed and maintained by the operation of the refraction operation mechanism part composing each refraction, which is the same as the raising and lowering state shown in FIGS. 1 and 2. be.

This shaping of the floorboard is done before placing the patient on it. To restore the original condition, use the handle bar 35~35c.
If the axes of the support rods 37a to 37c are aligned with the centers of the support rod insertion holes 342a to 342c, the leg floor plate 21 and the body floor plate 22 will come into contact with the frame member 11 and return to a horizontal state. Head floor plate 23
requires the same operation as above when selecting horizontal, upward or downward direction.

[Effects of the invention] As described above, this invention has a head floor plate 23 which is individually pivoted via hinge connecting parts 26, 26 to one end of the upper part of the underframe 1 having the legs 12 to 15 projecting downward. and the body floor plate 22 and this body floor plate 2
