BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of an obstetrics and gynecology examination table according to the present invention will be described with reference to the drawings.
1 to 3, reference numeral 1 denotes a base mounted on a floor surface, and 2 denotes a base that is rotatably supported on the base 1 by a support arm 1a (see FIGS. 4 to 6). A backrest 3, which is attached to the backrest 2 so as to be able to move up and down by a known up / down mechanism, is slidably attached to a lower portion of the backrest 2, and forms a seat surface when the backrest 2 is in an upright state, and when the backrest 2 is in a downside down state. 2 is a seat accommodated in the lower surface of the second seat. An armrest 2a is detachably attached to the backrest 2.
[0008]
Reference numeral 4 denotes a crotch receiving arm, which can be fixed on the back surface of the backrest 2 by an opening / closing mechanism described later to be operated separately for right and left, so that it cannot be rotated separately, and can be fixed at any position. The crotch support attached to the tip of the crotch receiving arm 4.
[0009]
Next, a mechanism for rotating the crotch receiving arm 4, which is a main part of the present invention, will be described with reference to FIGS.
5 is a guide rail fixed to the left and right lower portions of the backrest 2 and is formed into a curve that fits the thigh of the patient when the thigh of the patient placed on the crotch support 4a is opened. I have.
[0010]
Each of the guide rails 5 is provided with a roller, and a slide block 6 that moves smoothly along the guide rail 5 is attached. The rear end of the crotch receiving arm 4 is attached to the slide block 6. Accordingly, when the slide block 6 moves along the guide rail 5, the crotch support 4a is brought into the closed state in FIG. 2 and the open (leg open) state in FIG. A free ball 6a is formed on the surface of the slide block 6 opposite to the surface on which the crotch receiving arm 4 is mounted.
[0011]
Reference numeral 7 denotes an arm whose one end is pivotally supported by the support arm 1a of the base 1. Reference numeral 8 denotes a first rotating member whose one end is pivotally supported by a pin 7a at the other end of the arm. A part is rotatably supported on the fixed fixed shaft 2b. Reference numeral 9 denotes a second member rotatably supported on the fixed shaft 2 b inside the first rotating member 8. The spring 10 moves the second rotating member 9 in a direction in which the second rotating member 9 comes out of the first rotating member 8. Being energized. Reference numeral 11 denotes a stopper ring attached to an opening of the first rotating member 8 to prevent the second rotating member 9 from falling out of the first rotating member 8.
[0012]
The second rotating member 9 has projections 9a formed at intervals of 180 degrees. The projections 9a are formed in the ring-shaped grooves 8a formed on the first rotating member 8 or the grooves 8b formed at intervals of 180 degrees. Into any of the above. That is, in a state where the spring 9 is biased by the spring force, the projection 9a faces the groove 8b, and in a state where the spring 9 is opposed to the spring bias, the projection 9a is located in the ring-shaped groove 8a. It is configured to face.
[0013]
A tooth portion 2c is formed on the mounting surface side on which the fixed shaft 2b is mounted, and a tooth portion 9b is formed at the tip of the second rotating member 9 facing the tooth portion 2c. When pressed against the spring force, the two teeth 2c and 9b are engaged and locked. Further, a male screw 2d is formed at the tip of the fixed shaft 2b, and a knob 12 is screwed to the male screw 2d via a spacer 13.
[0014]
By configuring the first and second rotating members 8 and 9 in this manner, the second rotating member 9 is urged by the spring 10 when the knob 12 in FIG. The projections 9a are integrated in a state where they are located in the grooves 8b. Therefore, when the first rotating member 8 is rotated by the movement of the arm 7, the second rotating member 9 is also rotated.
[0015]
On the other hand, when the knob 12 of FIG. 8 is tightened against the spring force of the spring 10 and the teeth 9b of the second rotating member 9 mesh with the teeth 2c of the fixed shaft 2b, the protrusions 9a of the second rotating member 9 are formed. Moves into the ring-shaped groove 8a of the first rotating member 8, so that even if the arm 7 moves and the first rotating member 8 rotates, the second rotating member 9 is locked and rotated. Absent.
[0016]
Reference numeral 14 denotes a fixed arm having one end fixed in the vicinity of the fixed shaft 2b. Reference numeral 15 denotes a drive arm having one end pivotally supported at the tip of the fixed arm 14, and has a V-shaped guide hole 15a formed at an intermediate portion. A roller 9c attached to an extension of the second rotating member 9 is inserted into the guide hole 15a, and a C-shaped guide at the tip of which the free ball 6a is rotatably and slidably guided. The guide member 15b is formed integrally (see FIGS. 7 and 8).
[0017]
Hereinafter, the operation of the obstetrics and gynecology examination table according to the present invention will be described.
When the backrest 2 shown in FIGS. 1, 2 and 4 is in an upright state, that is, in a state where the patient is seated and the thigh is placed on the crotch support 4, the arm 7 and the first rotating member 8 are connected. Since the pin 7a is located below, the roller 9c of the second rotating member 9 moves to the left end of the guide hole 15a of the driving arm 15 via the first rotating member 8, and pushes the driving arm 15 upward. I have.
[0018]
Accordingly, the free ball 6a is pushed up by the guide member 15b, and the slide block 6 is moved above the guide rail 5. Thereby, the crotch receiving arm 4 has moved to the center side as shown in FIGS.
[0019]
Next, a case where a patient having no disease in the hip joint is treated will be described. That is, a case where the pair of left and right crotch receiving arms 4 are moved outward in conjunction with each other to open the legs will be described. In this case, as shown in FIG. 7, the knob 12 is loosened with respect to the male screw 2d of the fixed shaft 2b, and the protrusion 9a of the second rotating member 9 is fitted into the groove 8b of the first rotating member 8 to interlock. And set it to rotate.
[0020]
In this state, when the backrest 2 is turned down by a known raising / lowering mechanism, the arm 7 rotates the first rotating member 8 in the counterclockwise direction, so that the second rotating member 9 is also rotated in the counterclockwise direction. When the second rotating member 9 is rotated in the counterclockwise direction, the roller 9c moves toward the center of the guide hole 15a of the drive arm 15, so that the drive arm 15 pivots on a shaft support with the fixed arm 14. Is also rotated counterclockwise.
[0021]
Therefore, since the universal ball 6a guided by the guide member 15b of the drive arm 15 rotated counterclockwise moves downward while being guided by the guide member 15b, the slide block on which the universal ball 6a is mounted. 6 moves downward of the guide rail 5. As a result, the crotch receiving arm 4 rotates outward with a curve that matches the thigh opening of the patient, so that the thighs supported by the crotch receiving unit 4a are opened.
[0022]
Further, in the above-mentioned falling-down operation, the backrest 2 further falls down beyond the falling-down position in FIG. 5, and the roller 9c moves beyond the top of the guide hole 15a. Since the crotch receiving arm 4 does not move in the inside 15b, the crotch receiving arm 4 does not forcibly rotate outward and is in a free state. Therefore, the patient is not forced to open the legs excessively and does not cause unnecessary pain to the patient.
[0023]
Further, during the opening of the legs, the knob 12 is tightened against the spring force of the spring 10, and the second rotating member 9 is pressed to move the protrusion 9a toward the ring-shaped groove 8a. Does not rotate in conjunction therewith, so that the crotch support 4a can be fixed at a desired open position regardless of the amount of the backrest 2 falling down.
[0024]
After the treatment is completed, the backrest 2 is erected to cause the arm 7 to rotate the first rotating member 8 clockwise, and the crotch receiving arm 4 is closed by the operation reverse to the above-described operation. The patient's thigh supported by the crotch support 4a is closed and returns to the initial state.
[0025]
Next, a case where a patient has a disease in the hip joint and only one leg is opened will be described.
For example, when one crotch is to be opened and the other crotch is not to be opened, the knob 12 on the side to be opened is loosened, and the knob 12 on the side not to be opened is tightened, so that the one crotch receiving arm 4 is on the back. The other crotch receiving arm 4 is closed and fixed in a closed state because the first and second rotating members 8 and 9 are not interlocked with each other in response to the reclining of the backrest 2 and the pivoting movement in the leg opening direction. .
[0026]
When both legs are opened halfway, the backrest 2 is turned down with both knobs 12 loosened, and both knobs 12 are moved in a state where the legs are partially opened. By tightening, the crotch support 4a is fixed irrespective of the further reclining of the backrest 2 from the above description of the operation. Therefore, no pain is given to a patient having a hip joint disease.
[0027]
Note that the above-described guide rail 5 is not limited to the above-described shape, and may have any shape as long as the thigh of the patient can be easily opened. In addition, the interlocking operation and the non-interlocking operation of the first and second rotating members 8 and 9 are not limited to the above-described embodiment. For example, an electromagnetic lock excited by a switch operation can be used. .
[0028]
【The invention's effect】
As described above, according to the present invention, the connecting mechanism that connects the arm displaced by the backrest undulation and the crotch receiving arm is set to a non-connected state by an external operation, and the crotch receiving arm is not interlocked with the backrest undulation. Are fixed, so that the crotch supports can be operated separately for the left and right, and the left and right crotch supports can be fixed so that the legs are not independently opened, and any opened legs can be fixed. It can be fixed in position and therefore does not harm the patient with hip disease.
[0029]
Further, since the guide rail for displacing the crotch receiving arm in the opening / closing direction is formed in a curve adapted to the patient's thigh leg opening, an unreasonable external force does not act on the hip joint when the leg is opened. It has the effect of.
