[0001]
[Field of the Invention]
The present invention relates to an examination table that can be used for both internal and external examinations mainly in gynecological examinations.
[0002]
Problems to be solved by the prior art and the invention
As shown in FIG. 8, the gynecological examination table can be switched from a bed type that supports the patient in a lying position to a birth type in which the patient's legs can be bent from the knees and both legs can be held in the open position. (Patent Document 1).
The examination table comprises a waist plate (2) for supporting the buttocks of the patient, a back plate (3) for supporting the back, and two leg stands (4) and (4) for supporting the legs. (4) is provided so that it can be opened and closed.
Each of the footrests (4) includes a first footrest (5), a second footrest (6), and a first foot, each of which has a base end approaching and supported rotatably upward by a support bracket (57). An auxiliary part (50) is provided at the free end of the mounting part (5) so as to be bendable.
The first leg rest (5) supports the calf of the patient, the second leg rest (6) supports the sole, and the auxiliary part (50) supports the back of the thigh.
[0003]
As shown in FIG. 10, a first gear (51) is attached to the rotation center P1 of the first leg rest (5) so as to be integrally rotatable with the first leg rest (5). A second gear (52) meshing with the first gear (51) and a third gear (53) rotating integrally with the second gear are provided at the rotation center P2 of the second leg rest (6). It is mounted so that it can rotate independently of the rotation of.
An eccentric position of a lock gear (54) meshable with the third gear (53) is rotatably supported on the second leg rest (6), and the lock gear (54) is a torsion spring (FIG. (Not shown), and is always urged in a direction in which it meshes with the third gear (53).
A lock release handle (55) is connected to the lock gear (54).
[0004]
As shown by the two-dot chain line in FIG. 10, the free end of the second leg rest (6) is rotated upward to bend the extended leg stand (4). The third gear (53) meshing with the lock gear (54) rotates clockwise, and the second gear (52) also rotates integrally with the third gear (53). The first gear (51) meshing with the second gear (52) rotates counterclockwise.
The free ends of the second leg placing portion (6) and the first leg placing portion (5) are lifted up and bent in a V-shape.
The bending of the first leg rest (5) also raises the auxiliary part (50) that supports the back side of the thigh, but the movement of the auxiliary part (50) is regulated by the arm (56). The posture is bent downward with respect to (5).
When the lock release handle (55) is pulled and the lock gear (54) is eccentrically rotated to release the engagement with the third gear (53), the footrest (4) can be returned to the extended state.
[0005]
In the examination table, each footrest (4) is provided between the first footrest part (5) and the second footrest part (6) and between the first footrest part (5) and the auxiliary part (50). The bend and lock structure of the first leg rest (5) and the second leg rest (6) consists of four gears, a spring, a lock release handle and the like. Many and complicated.
In addition, the length of the patient's leg varies greatly from person to person, and the first leg rest (5), the second leg rest (6), and the auxiliary part (50) are each It is rare that the inflated shin, sole, and thigh are effectively supported at the same time. One or two of the first leg rest (5), the second leg rest (6), and the auxiliary part (50) often play without touching the patient's leg.
The angle of the first leg rest (5), the second leg rest (6) and the auxiliary part (50) cannot be adjusted independently. The angles of the one leg mounting part (5) and the auxiliary part (50) are determined.
For this reason, it is more difficult to simultaneously support the patient's leg at the three locations of the first leg rest portion (5), the second leg rest portion (6), and the auxiliary portion (50).
[0006]
As a result of observing the relationship between the patient's leg and the footrest (4) on the examination table, the applicant found that, with the patient bending the leg open, the patient could easily maintain the leg-bending posture and apply force to the leg. It has been found that a second leg rest (6) for supporting the sole of the patient is necessary and sufficient to facilitate the entry.
The present invention, based on the above observation results, clarifies an examination table that has a simple configuration and is easy to handle, and that can be used for both internal examination and external examination.

By inverting the second leg rest part (6), the flat part (61) and the sole receiving part (62) are turned upside down, and the flat part (61) is located above the sole receiving part (62). And the first posture, which is aligned with the extension of the mounting surface of the first leg mounting portion (5), and the sole receiving portion (62) is positioned above the flat portion (61), and the first leg mounting portion (5) ) Can be switched to the second posture inclined higher and forward than the mounting surface.
[0009]
[Action and effect]
In the case of an external examination, the footrests (4) and (4) are closed, and both the second footrests (6) and (6) on the tip end side of the footrests are placed on the flat feet (61) and (61). Switch to the first posture, which is aligned with the extension of the mounting surface of (5).
The patient lies on the hips on the hip plate (2), the back on the back plate (3), and both legs on the footrests (4) and (4).
In the case of a pelvic examination, both the second leg rests (6) and (6) are turned upside down, and the sole receiving parts (62) and (62) are inclined higher forward than the rest surface of the first leg rest (5). Switch to two positions.
The patient lies down on the hip plate (2) and his back on the back plate (3), and rests his feet on the sole receiving portions (62) and (62) with his knees bent.
When the footrests (4) and (4) are opened, the patient's legs open naturally.
Since the sole touches the sole receiving portion (62), when the body is stable and it is necessary to apply force to the leg, it is easy to apply force.
In both cases of external examination and internal examination, it is possible to adjust the angle of the back plate (3) to make the patient's posture easier and to make the patient take an optimal posture for the medical examination.
[0010]
When the external examination and the internal examination are performed on the same patient, after the external examination is completed, the patient bends the knee while lying down and pulls the sole to the first leg rests (5) and (5), and The leg rest (6) is opened. The opened second leg rests (6) and (6) are reversed to switch to the second posture.
The patient then applies the sole to the sole receiving portions (62) (62).
The footrests (4) and (4) can be opened by the footrest opening / closing device (7) to allow the patient to take a leg-spreading posture.
As described above, when shifting from the external examination to the internal examination, the patient's posture can be changed without the patient getting off the examination table, and the examination can be smoothly performed.
[0011]
Further, switching the posture of the examination table from the external examination to the internal examination can be performed simply by inverting the second leg rest 6 and opening the two legs 4 so that the operation is simple.
In addition, there is no bent portion in the footrest (4), and only the second leg rest (6) is inverted with respect to the first leg rest (5). The configuration can be simplified.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
As shown in FIGS. 1 and 2, the examination table includes an elevating table (1), a waist plate (2) provided on the elevating table (1), on which a patient's hips are placed, and a back plate ( 3) and two footrests (4) and (4) on which the patient's legs are mounted.
In the following description, the front is the side of the footrest (4), and the rear is the side of the backboard (3).
[0013]
The lift (1) is provided with a support (13) via a lift (12) on a base plate (11) installed on the floor, and the support (13) is provided with the waist plate (2) on the base ( It is supported almost parallel to 11).
The elevating mechanism (12) is a known mechanism that vertically expands and contracts the pantograph mechanism (14) using a hydraulic cylinder (15).
[0014]
The waist plate (2) is formed in a horizontally long shape, and one end of the waist plate (2) is hinged to a support (13) and can be raised and lowered as shown by a two-dot chain line in FIG.
Below the waist plate (2), a housing-shaped paper holder (21) having an upper surface opening is provided.
[0015]
The back plate (3) is attached to the support base (13) so as to be tiltable with respect to the hip plate (2) in a prone state, and the tilt angle can be adjusted by a hydraulic cylinder (31) shown in FIG.
The angle adjustment range of the back plate (3) is −10 ° to 45 ° with respect to the extension of the waist plate (2).
A pillow (32) is provided at the rear of the back plate (3).
[0016]
Each footrest (4) includes a first leg rest (5) on the side of the waist plate (2) and a second leg rest (6) connected to the front side of the first leg rest (5). .
The footrests (4) and (4) are opened and closed right and left by a footrest opening / closing device (7) shown in FIGS.
[0017]
The footrest opening / closing device (7) connects the first footrest (5) and the support stand (13) of each footrest (4) with an outer main link (71) and an inner auxiliary link (72), respectively. Connect pivotally. Each main link (71) (71) is connected to a rotating means (74) for rotating the link about a pivot (73) (73) on the support (13).
The rotating means (74) has levers (76) and (76) protruding sideward at the base ends of the main links (71) and (71), and connects both levers (76) and (76) with a connecting rod (77). The hydraulic cylinder (75) is connected to the center of the connecting rod (77).
[0018]
The operation of the hydraulic cylinder (75) moves the connecting rod (77) forward or backward, forcibly rotating the main links (71), (71) in mutually opposite directions via the lever (76).
Due to the forced rotation of the main links (71) and (71), the auxiliary links (72) and (72) also rotate, and the first leg rests (5) and (5) approach or separate while rotating in the same plane. I do.
The upper surface of the first leg placing portion (5) has the same height as the upper surface of the waist plate (2).
[0019]
The auxiliary link (72) of the embodiment is shorter than the main link (71), and the interval between the main link (71) and the auxiliary link (72) is such that the rotation center (73) of the main link (71) is narrower. Has been deployed. Therefore, when the main link (71) opens and rotates, the auxiliary link (72) regulates the movement of the first leg rest (5), and the first leg rest (5) The rotation of the main link (71) in the direction opposite to the opening direction of the main link (71) is applied around the pivot (78) of the main shaft (78) to reduce the fully open angle of the first leg rests (5) and (5). is there.
[0020]
As shown in FIG. 1, the second leg mounting portion (6) has a flat portion (61) aligned with an extension of the upper surface (mounting surface) of the first leg mounting portion (5) and an angle adjustment between the flat portion (61). And a sole receiving portion (62) attached via a mechanism (9).
As shown in FIG. 7, a connecting shaft (80) protrudes from the center of a receiving portion (84) provided substantially at the center of the front end of the first leg mounting portion (5), and the connecting shaft (80) has a flat portion ( 61) is installed to be reversible.
[0021]
The flat part (61) is provided with a locking means (8) for the first leg rest part (5). The locking means (8) is composed of a rod (81) having a T-shaped handle (82) at the tip and two locks opened symmetrically to the receiving part (84) with the connecting shaft (80) interposed therebetween. It is constituted by holes (85) and (86).
The rod (81) is constantly biased toward the receiving portion (84) by the spring (83).
If the rod (81) is pulled against the spring (83), the tip of the rod escapes from one of the locking holes, and the second leg rest (6) can be turned around the connecting shaft (80). .
The second leg rest part (6) is in a first position in which the flat part (61) is up, the sole receiving part (62) is down, and the sole part (62) is up, and the flat part (61) is downward. Can be locked by switching to the second position.
[0022]
In the first posture state (FIG. 1) of the second leg placing portion (6), the upper surface (the placing surface) of the flat portion (61) and the upper surface (the placing surface) of the first leg placing portion (5) have a height. I get it. That is, the heights of the flat part (61), the first leg placing part (5) and the waist plate (2) are the same. In the state of the second posture (FIG. 2), the sole receiving portion (62) is inclined obliquely forward and upward from the tip of the first leg rest (5).
[0023]
The hydraulic cylinder for lifting (15), the hydraulic cylinder for raising and lowering the back plate (31), and the hydraulic cylinder for opening and closing the footrest (75) of the lifting platform (1) are provided by a single stepped foot switch group (10). Controlled by operation.
[0024]
However, in the case of the external examination, the footrests (4) and (4) are closed, the second leg rests (6) on the tip side of each footrest (4) are locked in the first position, and the flat part (61) is locked. To the height of the mounting surface of the first leg mounting portion (5).
The patient rests on the hip plate (2) with the buttocks on the back plate (3), and lays down on both legs on the footrests (4) and (4).
[0025]
In the case of a pelvic examination, both the second leg rests (6) are switched to the second position and locked, and the sole receiving parts (62) and (62) are inclined higher than the rest surface of the first leg rest (5).
The patient places the buttocks on the waist plate (2) and the back on the back plate (3), and places the soles against the sole receiving portions (62) and (62) with the knees bent.
At this time, the angle of the sole receiving portion (62) can be adjusted by the angle adjusting mechanism (9).
The hydraulic cylinder (75) of the footrest opening / closing device (7) is operated to open the footrests (4) and (4).
The patient naturally has legs open.
In both cases of external examination and internal examination, the height of the elevating platform (1) and the angle of the back plate (3) can be adjusted to make the patient's posture easier and to make the patient take the optimal posture. .
[0026]
Prior to the examination, the roll paper (22) is pulled out from the paper holder (21) below the waist plate (2) to the outside from between the waist plate (2) and the back plate (3), and put on the waist plate (2). Make sure that the patient's buttocks rest on the paper (22) to ensure hygiene.
[0027]
In the embodiment, the first leg placing portion (5) of each leg stand (4) is supported on the support stand (13) via two links (71) and (72), and the leg stand (4) (4) The reason why the full open angle is not excessively large is as follows.
In FIG. 5, when the footrests (4) and (4) are fully open, the distance L between the front ends of the first leg rests (5) and (5) necessary to secure a working space for internal medicine is , Determined empirically. At this time, the opening angle of the second leg placing portion (6) must not be wider than the angle α1 at which the patient's leg does not give a feeling of being twisted outward.
[0028]
The auxiliary link (72) is omitted, the first leg rest (5) is fixed to the tip end side of the main link (71), and the rotation of the main link (71) (71) causes the first leg rest (5) to rotate. (5) Assuming that (5) is fully opened, the position of the pivot (73), which is the center of rotation of the main link (71), is close to the first leg rest (5). As shown in FIG. 5, when the front ends of the first leg rests (5) and (5) are opened by a required length L, the full open angle α2 of the first leg rests (5) and (5) becomes the first angle shown in FIG. 5. The leg opening portions (5) and (5) become too large than the proper full open angle α1, and the patient is forced to take an unnatural posture such as twisting the legs outward.
[0029]
The first leg rests (5) and (5) are supported only by the main links (71) and (71), respectively, and as shown in FIG. 5, the required opening distance L between the first leg rests (5) and (5) is increased. In order to satisfy the above condition and to satisfy the appropriate maximum opening angle α1 of the footrests (4) and (4), the rotation center P of the main link (71) is moved beyond the waist plate (2) and toward the back plate (3). Keep away. This will hinder the installation of the paper holder (21) and the undulating support structure of the back plate (3).
In this embodiment, the first leg rest (5) is supported by two links, the main link (71) and the second link (72), so that the pivots, which are the rotation centers of the two links (71) and (72), are provided. (73) (73) can be brought closer to the first leg rest (5), thereby solving the above problem.
[0030]
In FIG. 1 to FIG. 4, reference numeral (44) denotes a water receiver which receives a patient's discharge and a chemical solution. Reference numeral (45) denotes a shielding plate for preventing the discharged material and the chemical solution from scattering toward the support base (13).
Reference numeral (40) indicated by a two-dot chain line in FIG. 1 denotes a footrest that can fix a patient in an open leg state during an operation requiring anesthesia, such as an abortion operation, or an examination. It can be detachably attached to the side attachment part (17) of 13).
[0031]
The description of the above embodiments is intended to explain the present invention, and should not be construed as limiting the invention described in the claims or reducing the scope thereof. Further, the configuration of each part of the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made within the technical scope described in the claims.
[0032]
For example, the inner link and the outer link of the main link (71) and the auxiliary link (72) for supporting the first leg rests (5) and (5) on the support base (13) so as to be openable and closable, have the following relations. However, the present invention is not limited to the above-described embodiment, and the configuration is not limited as long as the first leg rests (5) and (5) operate so that the fully open angle at the fully open position does not become too large.
Further, the examination table of the present invention can be used for examination and treatment of urology of men.
