Description

  The present invention relates to a leg placement table for colonoscopy and a bed for colonoscopy used in colonoscopy performed in tests and treatments such as colon cancer screening and detailed examination.

The colonoscopy for the examinee P is performed by a doctor D who performs a colonoscopy and a plurality of assistants who assist the doctor D and the examiner P.
The colonoscopy is performed by inserting a flexible colonoscope from the anus of the examinee P lying on the examination bed B. As shown in FIG. 22A, the posture of the examinee P at the time of insertion is a state in which the buttock is protruded in the left lateral position of the left side. Since the doctor D changes the posture of the examinee P a plurality of times in order to insert the colonoscope deeply during the examination, the examinee P is in the supine position at least once as shown in FIG. It will be in the state which assembled lower limbs PA.
That is, the examinee P must change his / her posture after the colonoscopy is inserted.
Further, the doctor D is located on the right hand side of the examinee P, that is, on the left side in FIG.

The examinee P must change his position, but cannot change his position successfully if he / she is elderly, obese, or paralyzed. In colonoscopy, analgesics, sedatives or intravenous anesthesia are frequently used. This is because the examination time takes about half an hour and the examination is accompanied by pains such as pain and abdominal fullness, so it is necessary to take the pain of the examinee P. In addition, the aforementioned drugs may be used for the purpose of anesthesia during advanced and time-consuming colonoscopy such as colonic mucosal detachment. When the medicine is used, it is impossible for the examinee P to spontaneously change the position. Further, when it is difficult to change the posture of the examinee P, it is painful to hold the lower limbs PA in the supine position.
On the other hand, the assistant is mainly classified into a person who mainly assists the doctor D and a person who assists the examinee P.
When the doctor D performs biopsy or treatment, the assistant who assists the doctor D passes the biopsy forceps to the doctor D, processes the collected biopsy specimen, or treats a device such as a hemostatic clip. Wear and prepare them, or give them to the doctor D for assistance. Apart from this, the assistant who assists the examinee P administers the drug from the instillation line of the examinee P, monitors the vital signs of the examinee P, and supports the posture change. However, if the examinee P is an elderly person, an obese person, or is paralyzed, it is difficult to provide smooth support even if there are multiple persons. In addition, after the examinee P is in the supine position, an assistant for holding the lower limbs PA is required to maintain the posture. The same applies when the examinee P is administered a sedative, and the number of assistants is greater than in the case described above. Further, when requested by the doctor D, the assistant performs assistance to apply the abdominal pressure by pressing the abdomen of the examinee P in the supine position, and assists the doctor D to facilitate the colonoscopy operation. However, in the conventional situation where the legs are crossed, the abdomen of the examinee P is not sufficiently tensioned, and the doctor D sometimes has difficulty in performing the colonoscopy operation.
On the other hand, from the viewpoint of the doctor D, when the examinee P in the supine position is in a state where the lower limbs PA are assembled, the lower limbs PA are often obstructed visually and spatially, which often hinders colonoscopy operation. It was. In addition, when the examinee P is in the left-side-down position with the left side down at the time of insertion, the bent lower leg PA1 of the examinee P may interfere with the colonoscopy operation. Furthermore, following the supine position during insertion of the colonoscope, the examinee P may change his position to the right-sided position with the right side down. At this time, since the examinee P must be in the right lateral position after straddling both lower leg PA1 across the colonoscope, it takes time to change the position, and both lower leg PA1 is operated in the colonoscope. It was often a hindrance.

In order to solve such a problem, a leg placing table 500 for colonoscopy as shown in FIG. 23 has been developed. The thigh placing table 500 for colonoscopy includes a plate-like base portion 510, three struts 530 erected on the base portion 510, and a thigh placing portion 520 supported by the strut 530. (See Non-Patent Document 1).
In the colonoscopy table mount 500 for the colonoscopy, when the examinee P changes from the left-side prone position to the supine position, the colonoscopy crus table 500 is placed on the lower side of the lower leg PA1 where the examinee P is lifted. The lower leg PA1 is placed on the lower leg placing part 520 and supported from below. For this reason, an assistant for holding the lower leg PA1 becomes unnecessary.

Even when the colonoscopy crus table 500 is used, when inserting the colonoscopy crus table 500 under the lifted lower limb PA of the examinee P, at least two people Need an assistant. One person is an assistant who quickly moves the crus table 500 for colonoscopy. The other person is an assistant who lifts the lower limb PA of the examinee P and places it on the lower leg mounting table 500 for colonoscopy.
Moreover, even when the examinee P is in the supine position, the colonoscopy leg mount 500 for colonoscopy often hits the arm of the doctor D, which hinders the colonoscopy operation.
Furthermore, when the examinee P changes from the supine position to the left-side-down position or the right-side-side-down position, the installed colonoscopy leg mounting table 500 is visually and spatially inserted in the subsequent colonoscope insertion by the doctor D. It is necessary to remove the leg placement table 500 for colonoscopy from the examinee P one by one. Since it takes time to remove the crus table 500 for colonoscopy, the stress applied to the doctor D and the caregiver is large.
Furthermore, in the colonoscopy, in order to make it easy for the doctor D to see the monitor M, indoor lighting is turned off. For this reason, since a person who processes a biopsy sample collected from the large intestine is dark at hand, it is necessary to prepare a small illuminator such as a flashlight separately.

The present invention was devised in view of the above circumstances, and reduces the number and burden of assistants involved in colonoscopy, while making it easier to change the posture of the examinee and reducing pain. Therefore, doctors can perform colonoscopy in a short period of time without stress without the examinee's lower limbs interfering with the operation of the colonoscopy. The purpose is to provide a bed.
Another aspect of the present invention is that an assistant can easily process a biopsy specimen during a colonoscopy performed while the illumination is darkened by having an illumination function. An object of the present invention is to provide a leg placement table for colonoscopy and a bed for colonoscopy, which can smoothly prepare peripheral devices.

The effect of the leg mounting table for colonoscopy according to the present invention will be described from the standpoints of the examinee, doctor, and assistant.
First, there is an advantage for the examinee that it is not necessary to assemble the lower limb when the colonic endoscope is inserted from the anus in the lateral position and then the supine position is obtained.
That is, when the body position is changed from the supine position to the supine position, it is not necessary to assemble the lower limbs as long as the crus are placed on the collateral stage for colonoscopy. For this reason, the stress during colonoscopy can be greatly reduced.
This is particularly effective when the examinee is elderly, obese or paralyzed, or is being administered a sedative.
Moreover, since it becomes easy to insert a colonoscope by a doctor as will be described later, the time required for the insertion is shortened, and the pain during the examination of the examinee is reduced. In particular, the posture change to the right-sided position can be easily changed because it is not necessary to straddle the colon endoscope simply by lowering the lower leg to the right hand side of the examinee, leading to reduction of stress on the examinee.

On the other hand, for the doctor, the lower limbs of the examinee are placed on the cranium table for colonoscopy at the time of colonoscopy, so that a space for operating the colonoscopy is surely secured. There is a merit. In addition, if the examinee's lower leg is placed on the colonoscopy table in the supine position, the abdomen may become tense and the abdominal pressure may be easily applied by the caregiver. This shortens the insertion time for endoscopy. In addition, when the examinee changes his position from the supine position, the lower leg mounting table can be easily moved to the retracted position, so that the subsequent operation of the large intestine endoscope is not disturbed visually and spatially.
For this reason, the colonoscopy can be performed more reliably and accurately, the time required for the colonoscopy can be shortened, and the stress on the doctor can be greatly reduced.

  Furthermore, there is a merit that less caregivers may be required than conventional colonoscopy. For the caregiver, there is also an advantage that the posture change of the examinee can be performed more easily and safely.

  In addition, by providing a light emitting unit that emits light to the outside of the large intestine endoscopic examination bed in the support unit or the main body unit, an assistant can easily process a biopsy specimen. .

  Furthermore, the large intestine endoscopic examination bed according to the present invention has a built-in one corresponding to a crus mounting table for large intestine endoscopic examination. Therefore, as with the mounting table, after inserting the colonoscope from the anus of the examinee who is in the lateral position, the series of operations to place the examinee in the supine position and lift the lower leg is performed with fewer assistants. It can be carried out. In addition to this effect, it also has the effects of shortening time, saving space, reducing the pain and distress of the examinee, reducing the stress on the doctor, and reducing the burden on the caregiver and stress.

  The crus table 100 for colonoscopy according to the first embodiment of the present invention is a subject who is in a supine position during a colonoscopy performed by inserting a colonoscope from the anus. It is a leg mounting table for colonoscopy that supports the lower leg PA1 of P. The mounting table 100 includes a base portion 110, a lower leg mounting portion 120 that supports the lower leg of the examinee P from below, and a support portion 130 that supports the lower leg mounting portion 120 movably with respect to the base portion 110. I have.

  In the present specification, as shown in FIG. 7, the lower limb PA refers to a portion including the foot, ankle, shin, knee, and thigh, and the lower limb PA1 refers to the distance from the knee to the ankle of the lower limb PA. PA2 refers to a portion above the knee of the lower limb PA.

The base portion 110 is a flat plate material and is coated with a synthetic resin such as vinyl for antifouling. The base 110 is placed on the examination bed B on which the examinee P lies during the colonoscopy. For this reason, a non-slip sponge or the like is provided on the back surface of the base portion 110 so as not to slip on the inspection bed B.
As shown in FIG. 1 and the like, the base portion 110 is formed in a pentagonal shape in which one corner of a rectangle is cut off.

Needless to say, the shape of the base 110 is not limited to that shown in FIG. For example, it may be circular, bowl-shaped or other shapes.
Moreover, the base part 110 can also be configured to be foldable in order to save space during storage. These modifications can be similarly applied not only to the above-described colonic examination crus table 100 but also to other embodiments described later.

A support portion 130 is erected on the base portion 110.
The support portion 130 has a cylindrical shape. The height of the support part 130 is set to be slightly shorter than the length dimension from the buttocks of the average adult to the back of the knee. This is to prevent the examinee P from suffering when placing the lower leg PA1 on the lower leg placing part 120 in the supine position.
That is, when the examinee P places the crus PA1 on the crus placement part 120 in the supine position, the crus PA1 has a height dimension of the support part 130, a thickness dimension of the base part 110, and a crus placement part to be described later. This is because it is at a height position that combines 120 thickness dimensions.
If the height of the support part 130 is too larger than the length dimension from the buttocks to the back of the knee, the lower back PA1 is placed on the lower leg placement part 120, and the waist rises. Maintaining posture is difficult.
The support part 130 supports a location off the center of the crus placement part 120. In the present embodiment, the end in the length direction of the crus placement part 120 is supported.

  On the back surface of the crus placement part 120, a cylindrical cylindrical part 121 that is fitted or fitted into the support part 130 is attached. The crus placement part 120 is parallel to the base part 110 in a state where the crus placement part 120 is attached to the support part 130. Further, by fitting the cylindrical body part 121 into the support part 130, the crus placing part 120 can be rotated horizontally around the support part 130 while maintaining a state parallel to the base part 110. become. That is, the lower leg placing part 120 is supported by the support part 130 and can be rotated between the retracted position EP and the inspection position IP.

The examination position IP is a position where the crus placement part 120 is located above the base part 110 (see FIGS. 1 and 4) and can support the examinee P's crus PA1 in the supine position from below. . The retracted position EP is a position where the crus placement part 120 is removed from above the base part 110, and insertion of the large intestine endoscope from the anus of the examinee P who is in a lateral position when inserting the large intestine endoscope. (See FIGS. 2 and 5).
The retracted position EP corresponds to the upper side of the lower leg PA1 of the examinee P who is in the lateral position with the knee bent and the buttock protruded. For this reason, from the doctor located on the back of the examinee P (doctor located on the left side in FIG. 5), the crus placement part 120 does not exist on the upper side of the buttocks. It does not interfere with the insertion of a large intestine endoscope from the anus.
Furthermore, the doctor side of the crus placement part 120 has a partially missing shape so that the arm of the doctor who operates the large intestine endoscope does not come into contact with the crus placement part 120 and the operation of the large intestine endoscope is performed. This is to make it easier to do. The reason why the examinee P side of the base part 110 is partially missing is to prevent the operating colonoscopy from touching the base part 110 and to facilitate the operation of the colonoscope. is there.

  For example, a low-resilience urethane resin 122 is affixed to the surface side of the lower leg placement unit 120 so that the lower leg PA1 of the examinee P does not slip and congestion does not occur in the lower leg PA1 during colonoscopy. It has been. The urethane resin 122 has a fluorescent or phosphorescent tape 123 attached to a position where the examinee P's lower leg PA1 is to be placed. The reason why the fluorescent or phosphorescent tape 123 is used is that it corresponds to the colonoscopy performed with the indoor illumination turned off.

  In addition, it is possible to change the design to the following configuration in addition to attaching the low resilience urethane resin 122 evenly on the entire surface side of the lower leg placing portion 120. For example, as illustrated in FIG. 6, the urethane resin 122 is not attached to the portion where the lower leg PA1 is placed, and the urethane resin 122 is attached to a portion other than the portion where the lower leg PA1 is placed. Thereby, the part on which the lower leg PA1 is placed is configured as a groove 124, and it is possible to prevent the lower leg PA1 from being displaced during the colonoscopy. In addition, it is desirable to attach a fluorescent or phosphorescent tape 123 to the groove 124.

A procedure for colonoscopy by the crus mounting table 100 for colonoscopy configured as described above will be described with reference to FIGS. 4 and 5.
As shown in FIG. 5, a cranium placement table 100 for colonoscopy is placed on the examination bed B before the colonoscopy. That is, the base part 110 of the crus table 100 for colonoscopy is set at a position where the examinee P's lower leg PA1 is supposed to be located. And it sets so that the support part 130 may be located in the left hand side of the examinee P (namely, the right side of the test bed B in FIG. 5).

  In this state, the examiner P lies on the examination bed B in a state in which the buttock is projected in the left lateral position on the left side. At this time, the crus placement part 120 is located in the retracted position EP (see FIG. 5). The doctor inserts the large intestine endoscope into the anus of the examinee P from the right hand side of the examinee P (that is, the left side of the examination bed B in FIG. 5).

When the insertion is completed, as shown in FIG. 4, the crus placement part 120 at the retracted position EP is rotated to the examination position IP. In both cases, the examinee P is placed in the supine position with the lower leg PA1 raised. As a result, the lower leg placement section 120 is positioned below the lower leg PA1 of the examinee P in the supine position. Note that the operation of placing the examinee P in the supine position and the operation of rotating the lower leg placement unit 120 horizontally can be performed by a single assistant.
In addition, FIG. 8, FIG. 17, FIG. 18, FIG. 20, FIG. 21, and FIG. 16, FIG. 17, FIG. 18, FIG. The large intestine endoscopic examination beds B1, B2, B3, and B4 are fully automatic, and can perform posture change without an assistant.
Since the fluorescent or phosphorescent tape 123 is affixed to the surface side of the crus placement part 120, it is possible to reliably place the lower limb PA1 in a predetermined position even in an examination room where illumination is turned off. .

Since the examinee P's lower leg PA1 rests on the lower leg placing part 120, it does not interfere with the colonoscopy. Further, since the doctor is located on the left side of the examination bed B, the support portion 130 located on the right side of the examination bed B does not interfere with the operation of the large intestine endoscope.
In the colonoscopy, the posture of the examinee P is generally changed several times. When the examinee P takes a posture other than the supine position, it is not necessary to support the lower leg PA1, and therefore the lower leg placing part 120 is retracted to the retracted position EP. As a result, the crus placement part 120 does not get in the way visually and spatially, which makes it easier for the doctor to perform a colonoscopy operation and reduces the stress on the doctor. In particular, when the examinee P takes the right-side-down position with the right side down, the right and left lower leg PA1 may be lowered from the supine position to the doctor D side to take the right-side position. At this time, if there is a crus table 100 for colonoscopy, it does not cross the colonoscopy, so that the posture of the examinee P can be easily changed. In addition, since the crus placement part 120 is retracted to the retracted position EP, the crus placement part 120 does not interfere with the operation of the colonoscope.

  When the colonoscopy is completed and the colonoscope is removed, wipe the dirt on the buttocks and anus. Thereafter, if the posture at the end of the colonoscopy is the supine position, the lower leg PA1 placed on the lower leg placing part 120 is slightly lifted, and the lower leg placing part 120 is horizontally rotated to the retracted position EP. Lower the lower leg PA1 to the examination bed B.

  In the colonoscopy, the contamination of the examination bed B and the base portion 110 of the colonoscopy crus table 100 is dealt with by placing vinyl sheets or pads on these. .

In the above-described crus mounting table 100 for large intestine endoscopy, the crus mounting part 120 is horizontally rotatable. However, it is also possible to adopt a configuration in which the crus placement part 120A can be rotated in the vertical direction as in the examination crus rest 100A according to the second embodiment shown in FIG. Other than this, the inspection crus rest 100A can have the same configuration as the inspection crus rest 100.
The crus mounting table 100A for colonoscopy has nothing equivalent to the cylindrical part 121, and the crus mounting part 120A rotates around the horizontal axis 131A at the upper end of the support part 130A erected on the base part 110A. It is hinged to move.
The inspection position IP is such that the crus placement part 120A is parallel to the base part 110A. The retreat position EP is rotated 90 degrees upward from the inspection position IP, and stands upright with respect to the base 110A.

  In addition, it is important from the viewpoint of safety to provide a locking mechanism (not shown) so that the crus placement part 120A in the retracted position EP does not fall carelessly in the crus rest 100A for colonoscopy.

  A urethane resin 122A is attached to the surface side of the crus placement part 120A of the crus rest 100A for colonoscopy. A fluorescent or phosphorescent tape indicating the placement position of the lower leg PA1 is affixed to the surface side of the urethane resin 122A, but the illustration is omitted in FIG. 8 for convenience of drawing.

  Further, if a leg drop prevention wall or a leg fixing bar (not shown) raised from the other part is formed on the short side edge of the crus placement part 120A, the crus placement part 120A can be used when changing the posture. It is possible to prevent the placed lower leg PA1 from falling. Therefore, by providing the foot drop prevention wall, it is possible to perform the posture change more safely even if there is no assistant even if the posture change is performed automatically.

  Further, like the crus mounting table 100B for colonoscopy according to the third embodiment of the present invention shown in FIG. 9, the crus mounting part 120B has two plates 120B1 and 120B2. Is possible. The plate material 120B1 is fixed to the support portion 130B horizontally. The plate members 120B1 and B2 can be configured to be hinged so that the plate members 120B1 and B2 can be opened and closed. As shown in FIG. 9A, the plate members 120B1 and 120B2 are overlapped with each other in the closed state (retracted position EP). As shown in FIG. 9B, the plate materials 120B1 and 120B2 become one plate material in an open state (inspection position IP).

  The support portion 130B is erected on the base portion 110B, and the urethane resin 122B is affixed to the surface side of each plate member 120B1 and 120B2. The above-described leg placement table for colonoscopy is described above. Similar to 100 and 100A. In addition, a fluorescent or phosphorescent tape indicating the placement position of the lower leg PA1 is affixed to the surface side of the urethane resin 122B, but is not shown in FIG. 9 for the sake of drawing.

Further, like the crus table 100C for colonoscopy according to the fourth embodiment of the present invention shown in FIG. 10, the crus placement part 120C has two plates 120C1 and 120C2. Is possible. The plate member 120C1 is connected to the tip of the support portion 130C so as to be rotatable in the vertical direction, similarly to the crus placement portion 120A. The plate member 120C2 is slidably attached to the plate member 120C1 and can be stored in the plate member 120C1.
A state in which the plate member 120C1 is oriented in the vertical direction and the plate member 120C2 is accommodated in the plate member 120C1 is the retracted position EP of the crus rest 120C. The state where the plate material 120C1 faces in the horizontal direction and the plate material 120C2 protrudes from the plate material 120C1 is the inspection position IP of the crus placement part 120C.

  The support portion 130C is erected on the base portion 110C, and the urethane resin 122C is attached to the surface side of each of the plate members 120C1 and 120C2. The above-described leg placement table for colonoscopy is described above. The same as 100 to 100B. In addition, a fluorescent or phosphorescent tape indicating the placement position of the lower leg PA1 is affixed to the surface side of the urethane resin 122C, but is not shown in FIG. 10 for the sake of drawing.

  Furthermore, if a foot drop prevention wall and a crus fixing bar (not shown) raised from the other parts are formed on the short edge portions of the plate member 120C1 and the plate member 120C2, the crus placement unit 120C is used when changing the posture. It is possible to prevent the lower leg PA1 placed on the body from falling. Therefore, by providing the foot drop prevention wall, it is possible to perform the posture change more safely even if there is no assistant even if the posture change is performed automatically.

  Alternatively, the crus placement part 120D can be configured to be detachable from the support part 130D, such as the crus placement table 100D for colonoscopy according to the fifth embodiment of the present invention shown in FIG. It is. A cylindrical tubular portion 121D is attached to the back side of the crus placement portion 120D. This cylindrical part 121D is fitted or fitted into the support part 130D. In this case, it is possible to attach the crus placement part 120D to the support part 130D only when the examinee P is placed in the supine position with the crus PA1 assembled. When the body is in a position other than the supine position, the crus placement part 120D can be rotated horizontally and moved from the examination position IP to the retracted position EP.

  The mounting table 100D has the same configuration as the mounting table 100 except that the cylindrical body part 121D is detachable from the support part 130D. In FIG. 11, 122D is a urethane resin. A fluorescent or phosphorescent tape indicating the placement position of the lower leg PA1 is affixed to the surface side of the urethane resin 122D, but is not shown in FIG. 11 for the sake of drawing.

Next, a crus placing table 100E for colonoscopy according to a sixth embodiment of the present invention will be described with reference to FIG.
The crus mounting table 100E for colonoscopy differs from the mounting table according to the above-described embodiment in that the support portion 130E can be expanded and contracted.
As an example of the support portion 130E, a lattice structure is used as shown in FIG. This structure is also referred to as a magic hand structure. In the colonoscopy crus rest table 100E, as shown in FIG. 12A, the crus rest part is in a state where the support part 130E is most contracted. 120E is stacked on the upper side of the base portion 110E. At the retracted position EP, the lower leg placing portion 120E does not get in the way regardless of the posture of the examinee P. The support part 130E is extended and the lower leg placing part 120E is raised. Thereby, the lower leg mounting part 120E can support the lower leg PA1.

In such a thigh placement table 100E for colonoscopy, the support portion 130E is extended and the height position (examination position IP) of the thigh placement portion 120E can be freely changed according to the physique of the examinee P. Therefore, there is an advantage that a smoother colonoscopy can be performed.
However, carelessly changing the height of the crus placement part 120E during the colonoscopy may lead to a medical accident. Therefore, the crus placement for the colonoscopy having the extendable support part 130E is possible. In the mounting table 100E, a structure in which the support portion 130E is firmly fixed so that the height of the crus mounting portion 120E does not change carelessly becomes important.

  Except for the above, the mounting table 100 </ b> D has the same configuration as the mounting table 100. A fluorescent or phosphorescent tape indicating the position of the lower leg PA1 is attached to the surface side of the urethane resin 122E. However, in FIG. 12, illustration is omitted for the sake of drawing.

  In addition, in this crus mounting table 100E for colonoscopy, if the change of the height of the crus mounting part 120E is automatically performed using an appropriate driving means such as a motor, an assistant at the time of posture change There is also an advantage that becomes unnecessary.

Next, a crus placing table 100F for colonoscopy according to a seventh embodiment of the present invention will be described with reference to FIG.
The crus placement table 100F for colonoscopy is configured to move between the retracted position EP and the examination position IP as the crus placement part 120F slides along the support part 130F. For this reason, the support portion 130F has a proximal end portion and a distal end portion. The base end portion is erected on the base portion 110F and is perpendicular to the base portion 110F. The distal end portion is curved with respect to the proximal end portion so as to be parallel to the base portion 110F. It can be said that the support portion 130F is formed in a substantially inverted J shape, arc shape, or elliptical shape.

In the mounting table 100F, a groove portion (not shown) is provided in the support portion 130F, and a protrusion (not shown) that engages with the groove portion is provided in the crus mounting portion 120F. And a projection part fits into the groove part, and the crus placement part 120F is freely slidable along the support part 130F. It is to be noted that the structure in which the crus placement part 120F at the examination position IP does not inadvertently change the position is important as in the case of the support part 130E described above.
In this structure, the retracted position EP is when the crus placement part 120F is positioned at the lowermost side of the support part 130F (see FIG. 13A), and the inspection position IP is when it is positioned at the uppermost side (see FIG. 13). 13 (B)). Therefore, the crus placement part 120F in the retracted position EP is substantially perpendicular to the base part 110F.

  The support portion 130F is erected on the base portion 110F, and the urethane resin 122F is attached to the surface side of the crus placement portion 120F. The above-described crus placement table for colonoscopy is described above. It is the same as 100. In addition, a fluorescent or phosphorescent tape indicating the position of the lower leg PA1 is affixed to the surface side of the urethane resin 122F, but is not shown in FIG. 13 for the sake of drawing.

  Furthermore, if a leg drop prevention wall or a crus fixing bar (not shown) raised from the other part is formed on the short side edge of the crus placement part 120F, the crus placement part 120F can be used when changing the posture. It is possible to prevent the placed lower leg PA1 from falling. Therefore, by providing the foot drop prevention wall, it is possible to perform the posture change more safely even if there is no assistant even if the posture change is performed automatically.

As described above, the crus rests 120 to 120F are placed between the retracted position EP and the examination position IP in the crus rests 100 to 100F for colonoscopy according to the first to seventh embodiments. Examples of the structure for movement include rotation, folding, sliding, attachment / detachment, and expansion / contraction, but the present invention is not limited to this.
Needless to say, moving the lower leg placing portions 120 to 120F between the retracted position EP and the inspection position IP includes not only manual operation but also automatic operation. Moreover, the operation is not only directly operated by an operation switch provided on the collateral endoscopic examination leg mounting table 100 to 100F itself, but also provided separately from the collateral endoscopic examination leg mounting table 100 to 100F. It also includes a structure for operating via a remote control device.

  In particular, on the above-described large intestine endoscopic examination crus rests 100A, 100C, 100F, as in a leg drop prevention wall B232 of the crus rest B23 shown in FIG. 17 described later, the crus rests 120A, 120C, 120F. If a leg drop prevention wall (not shown) raised from the other part and a crus fixing bar B332 shown in FIG. 20 are formed on the short side edge of the crus, the crus placement parts 120A, 120C, The lower leg PA1 placed on 120F can be prevented from falling. Therefore, by providing the foot drop prevention wall, it is possible to perform the posture change more safely even if there is no assistant even if the posture change is performed automatically.

Further, in the above-described large intestine endoscopic examination thigh placing tables 100 to 100F according to the first to seventh embodiments, the base portions 110 to 110F are placed on the examination bed B on which the examinee P lies. However, the base part itself can be changed to the inspection bed B.
For example, the support portions 130 to 130D and 130F become the base portions 110 to 110D and 110F as in the large intestine endoscopic examination leg mounting tables 100 to 100D and 100F according to the first to fifth and seventh embodiments. It is detachable with respect to the opening provided in the examination bed B, and only when performing a colonoscopy, the support portions 130 to 130D and 130F are attached to the examination bed B and mounted on the lower leg. What is necessary is just to make it attach to mounting part 120-120D, 120F.
The opening may be a simple hole or a female screw type hole.

  Further, the support portions 130 to 130D and 130F are not attached to the holes of the inspection bed B but are incorporated so as to be embedded in the inspection bed B, and only on the surface side of the inspection bed B when necessary. You may be comprised so that it can protrude.

Further, it is possible to adopt a configuration in which the crus mounting table 100E for colonoscopy according to the sixth embodiment is incorporated in an examination bed. As shown in FIG. 16, the large intestine endoscopic examination bed B1 forms a storage recess B12 for accommodating the crus placement part 120E in the main body B11 of the large intestine endoscopic examination bed B1. The support portion 130E is erected on the bottom surface of the storage recess B12. What is necessary is just to comprise so that the crus mounting part 120E is stored in the storage recessed part B12 in the retracted position EP where the support part 130E is contracted most, and is flush with the main body part B11.
In this way, integrating the base portions 110 to 110F with the bed for examination is from the viewpoint of saving space, shortening examination time, reducing stress on the doctor, reducing the number and burden of assistants, reducing stress, and reducing pain on the examinee. Is desirable.

Next, referring to FIG. 14, a description will be given of the leg placement table 100G for colonoscopy provided with the light emitting unit 132G.
The crus table 100G for colonoscopy according to the eighth embodiment of the present invention performs processing of a biopsy sample collected from the large intestine by colonoscopy performed while the illumination is darkly turned off. It is possible to illuminate the caregiver's hand so that the user can easily wear the treatment device and prepare peripheral devices.

  This trochanteric table 100G for colonoscopy is a colonoscopy that supports the leg of the examinee P who is in a supine position during a colonoscopy performed by inserting a colonoscope through the anus. It is a leg mounting table. The mounting table 100G includes a base portion 110G, a crus placement portion 120G that supports the lower leg PA1 of the examinee P from below, and a support portion 130G that supports the crus placement portion 120G on the base portion 110G.

  The support portion 130G supports the crus placement portion 120G fixedly with respect to the base portion 110G, and has a cylindrical shape with a cavity inside. The support part 130G supports a location deviated from the center of the crus placement part 120G. In the present embodiment, support portion 130G supports the end portion in the length direction of crus placement portion 120G. As shown in FIG. 14A, the support portion 130G is provided with a light emitting portion 132G that emits light to the outside of the crus rest table 100G for colonoscopy. The light emitting unit 132G is exposed from one surface of the support unit 130G (that is, the surface facing the outer side of the large intestine endoscopic examination thigh mounting table 100G). As the light emitting unit 132G, at present, a light emitting diode is excellent in terms of power saving, space saving, illuminance, and the like, but other light emitting elements can also be used. The light emitting part 132G has a light emitting part only on the side of the examinee P and the doctor D in the entire periphery of the support part 130G so that the doctor D can easily see the monitor so that the examinee P is not dazzled and can illuminate the hand of the assistant. It may be a structure in which a cover is covered.

The light emitting unit 132G uses a battery stored in the support unit 130G as a power source. Therefore, the support portion 130G is provided with a battery storage portion (not shown) and a lid for opening and closing the battery storage portion. In addition, a switch for turning on and off the light emitting unit 132G is provided in the support unit 130G. In addition, the said switch is not limited only to what is provided in the support part 130G. For example, the switch can be provided in the other part of the leg mounting table 100G for colonoscopy. In addition, the switch can be provided as a remote control device that is separate from the crus table 100G for colonoscopy.
Further, as shown in FIG. 14B, a light-transmitting material is used as a window 133G on the surface of the support portion 130G facing the outer side of the large intestine endoscopic examination thigh mounting table 100G to support the light emitting portion 132G. It is also possible to store in the part 130G.

  In addition, the support part 130G of the crus placement table 100G for colonoscopy is erected on the base part 110G, and the urethane resin 122G is attached to the surface side of the crus placement part 120G. These are the same as the above-described crus rests 100-100F for colonoscopy. In addition, a fluorescent or phosphorescent tape indicating the placement position of the lower leg PA1 is affixed to the surface side of the urethane resin 122G, but is not shown in FIG. 14 for convenience of drawing.

The light emitting unit 132G described above can also be provided on the crus rest table 100H for colonoscopy according to the ninth embodiment of the present invention. In the crus placement table 100H for colonoscopy, the crus placement part 120G is movable between the retracted position EP and the examination position IP.
For example, as shown in FIG. 15, a cylindrical body 121H is formed on the back surface of the crus placement part 120H. The cylindrical portion 121H is externally fitted to a support portion 130H provided upright on the base portion 110H. For this reason, the crus placement part 120H can be rotated horizontally around the support part 130H as a fulcrum. The entire circumference of at least the portion of the cylindrical portion 121H that the light emitting portion 132H faces is configured as a window 125H made of a translucent material. This is because the cylinder part 121H rotates with the rotation of the lower leg placing part 120H.

  The support portion 130H is erected on the base portion 110H, and the urethane resin 122H is attached to the surface side of the crus placement portion 120H. The above-described crus placement table for colonoscopy is described above. The same as 100 to 100G. In addition, a fluorescent or phosphorescent tape indicating the placement position of the lower leg PA1 is attached to the surface side of the urethane resin 122H. However, in FIG. 15, illustration is omitted for the sake of drawing.

  The leg mounting tables 100G and 100H for colonoscopy having the light emitting portions 132G and 132H are biopsies collected from the body not only in colonoscopy but also in upper gastrointestinal endoscopy. It can also be used as illumination for illuminating the hand of an assistant handling the specimen.

  The bed B2 for colonoscopy shown in FIG. 17 and FIG. 18 is a body part B21 on which the examinee P lies, an elevating part B22 that moves the body part B21 up and down, and a body part B21. The lower leg mounting part B23 that supports the lower leg PA1 of P from below, and the support part B24 that supports the lower leg mounting part B23 so as to be movable between the retracted position EP and the inspection position IP.

The crus placement part B23 is formed in a horizontally elongated substantially rectangular parallelepiped shape as a whole. The crus placement part B23 is stored in the main body part B21 so that the side surface B231 on one short side is flush with the surface of the main body part B21. This stored state is the retracted position EP of the crus placement part B23. The crus placement part B23 exits from the main body part B21 and is parallel to the main body part B21. This state is the inspection position IP of the crus placement part B23.
The other short side of the lower leg placement part B23 is raised from the other part. This raised portion serves as a foot drop prevention wall B232 that supports the lower leg PA1 placed on the lower leg placing part B23 so as not to fall. The body B21 adjacent to the side surface B231 is provided with a lid B233 that can be opened and closed so that the foot drop prevention wall B232 can come out of the body B21. When the crus placement part B23 is in the retracted position EP and the lid body B233 is in a closed state, the lid body B233 and the side surface B231 are flush with each other on the surface of the main body part B21.

As shown in FIG. 17, the support portion B24 includes a substantially arc-shaped rack gear portion B241, a pinion gear portion B242 corresponding to the rack gear portion B241, and a drive device (not shown) that rotates the pinion gear portion B242. have. A plurality of convex portions B243 corresponding to the plurality of concave portions B234 formed on the back surface of the crus placement portion B23 are formed on the back side of the rack gear portion B241 (the surface side facing the surface corresponding to the pinion gear portion B242). ing.
The rack gear portion B241 is preferably a round bar. This is because if the rack gear portion B241 has a round bar shape, the possibility that the examinee P will be injured can be reduced even if it contacts the examinee P.

  The end surface B244 of the rack gear B241 is exposed on the surface of the main body B21. In addition, a fluorescent paint or a phosphorescent paint that emits light even in the dark is applied to the start side end face B244. For this reason, the position of the rack gear portion B241 can be visually confirmed even at the time of inspection with the illumination turned off. Moreover, as shown in FIG. 18 (A), the position where the start end side end face B244 of the rack gear portion B241 is exposed corresponds to the back side of the kneecap of the examinee P who has bent the lower leg PA1 and is in the lateral position. There is also an advantage that it becomes an index of the posture of the examinee P. A fluorescent paint or a phosphorescent paint may be applied to the side surface B231. Note that the fluorescent paint or phosphorescent paint can be replaced with a fluorescent tape or phosphorescent tape.

  The convex part B243 of the rack gear part B241 meshes with the concave part B234 of the crus placement part B23 when the crus placement part B23 is moved between the retracted position EP and the inspection position IP. Therefore, when the pinion gear portion B242 is rotated by the drive device when the lower leg placement portion B23 is at the retracted position EP, the rack gear portion B241 starts to protrude toward the main body portion B21, and the lower leg placement portion B23 starts to protrude according to the movement of the rack gear portion B241. The placement unit B23 starts moving from the retracted position EP to the inspection position IP.

In the state where the crus placement part B23 is at the retracted position EP, the convex part B243 of the rack gear part B241 and the concave part B234 of the crus placement part B23 are not engaged with each other, and the rack gear part B241 is engaged after the movement starts. It is preferable to keep it.
This is because, as shown in FIG. 18B, the crus placement part B23 can start to move from the point when the start end side end face B244 of the rack gear part B241 slightly protrudes from the surface of the main part B21. In this case, since the movement of the crus placement part B23 is started after a certain time from turning on the switch for driving the driving device, it is safe even when the posture of the examinee P collapses after the switch is turned on. Can respond. Moreover, when it is the structure where the lower leg mounting part B23 was provided with the lower leg fixing bar, the safety of the bed B2 is improved.

  When the crus placement part B23 starts to move to the inspection position IP, the crus placement part B23 moves while sliding on the back side of the examinee P's lower leg PA1. Then, as shown in FIG. 18C, when the lower leg PA1 hits the foot drop prevention wall B232, the lower leg PA1 of the examinee P starts to move as the lower leg placing portion B23 moves. Begin to change position from the supine position to the supine position.

  In the colonoscopy bed B2 configured in this way, the rack gear portion B241 of the support portion B24 is formed in an arc shape. At the inspection position IP, the distal end portion of the support portion B24 supports the crus placement portion B23, and the proximal end portion of the support portion B24 is deviated from the center of the crus placement portion B23 (foot drop prevention wall B232). (Below). For this reason, support part B24 does not become a hindrance to colonoscopy operation.

  Then, as shown in FIG. 18D, when the crus placement part B23 reaches the examination position IP, the examinee P assumes the supine position with the crus PA1 placed on the crus placement part B23.

  As shown in FIG. 18D, if a light emitting part B245 is provided on the base side of the rack gear part B241 constituting the support part B24 toward the outside of the colonoscopy bed B2, the assistant There is an advantage that biopsy specimens can be processed more easily. The light emitting unit B245 emits light to the outside of the bed B2. The light emitting unit B245 can have the same configuration as the light emitting units 132G, 133G, and 132H. A light-transmitting window or the like can also be formed in the rack gear portion B241.

The light emitting part B245 of the colonoscopy bed B2 is incorporated in the rack gear part B241. However, a configuration as shown in FIG. 19 is also possible.
The light emitting unit B25 shown in FIG. 19 is hinged to the main body B21 of the colonoscopy bed B2. The light emitting unit B25 includes a synthetic resin plate B251 having a light-transmitting surface and a light emitting element such as a light emitting diode provided inside the synthetic resin plate B251.
As shown in FIG. 19B, the light emitting portion B25 can be fixed in a state where it is flush with the synthetic resin plate B251 and the main body portion B21.
When the plate-like light emitting part B25 is provided in the main body part B21 in this way, the light emitting part B25 can also be used as a table when processing a biopsy specimen.

  The light emitting element is configured to automatically turn on when the plate-like light emitting part B25 is in use with the main body B21, and to be turned off when not used with the main body B21 bent at 90 degrees. can do. The light emitting element may be configured to be turned on and off with a switch regardless of the state of the light emitting unit B25. This switch may be incorporated in the main body B21 or may be a separate remote control device.

  The light emitting section B25 is provided not only on the colonoscopy bed B2, but also on the aforementioned colonoscopy bed B1, the colonoscopy bed B3 described later, or the colonoscopy bed B4 described later. Can also be applied.

Next, the colonoscopy bed B3 shown in FIG. 20 will be described.
The large intestine endoscopic examination bed B3 is a large intestine endoscopic examination bed on which the examinee P lies during the large intestine endoscopic examination performed by inserting the large intestine endoscope from the anus. The bed B3 supports a body part B31 on which the examinee P lies, a crus placement part B33 that supports the lower leg PA1 of the examinee P from below, and the crus placement part B33 movably with respect to the body part B31. And a support portion B34.

  In the colonoscopy bed B1 and the like described above, the main body B11 on which the examinee P lies is not deformed except for the crus placement part 120E, but the colonoscopy bed B3 shown in FIG. The body part B31 is deformed so that the posture change of the examinee P can be performed more easily and safely.

The main body B31 has a seating surface part B311 on which the buttocks of the examinee P is placed, a reclining backrest part B312 that receives the back part of the examinee P, and an instrument placement table B313 on which a colonoscopy or the like is placed. From the upper side (head side) of the main body B31, a backrest B312, a seating surface B311, and an instrument mounting table B313 are formed.
In addition, this main-body part B31 can be moved up and down by the raising / lowering part B32. The bed B3 further includes a reclining mechanism (not shown). By this reclining mechanism, the seat surface portion B311 and the backrest portion B312 can be tilted with respect to the elevating portion B32, while the backrest portion B312 can be tilted with respect to the seat surface portion B311. The instrument mounting table B313 can be expanded and contracted with respect to the seat surface part B311. The backrest part B312, the crus placement part B33, and the support part B34 can be rotated around the longitudinal axis L (see FIG. 20B) of the main body part B31 in a state where the backrest part B312 is lying. This rotation enables the examinee P to change the posture of the examinee P between the lateral position and the supine position without changing the posture.

  In the initial state of the colonoscopy bed B3, as shown in FIG. 20A, the backrest portion B312 is raised, the seat surface portion B311 is positioned horizontally, and the instrument mounting table B313 is incorporated into the seat surface portion B311. ing.

  In addition, since the backrest B312 is configured such that the left and right edges rise more than the other parts, it is possible to fix the upper body of the examinee P (however, for the convenience of drawing, the left and right edges The illustration of the rise of the part is omitted.)

The backrest B312 is provided with an opening B314 so that the colonoscopy bed B3 can also be used as an upper gastrointestinal endoscopy bed. In the upper gastrointestinal endoscopy, in order to relax the examinee P, the assistant may point to the back of the examinee P in the left position. The assistant can insert his / her hand through the opening B314 and point to the back of the examinee P.
Note that the opening B314 may be provided with a sliding sliding door or a detachable door, or may not be provided with a door. In this upper gastrointestinal endoscopy, since the fiber is inserted from the mouth instead of the anus, the seat surface B311 remains the seat surface, and the design is changed so as to move in conjunction with the support portion B34 and the crus placement portion B33. It is possible.

  On the other hand, the support portion B34 has a base end portion connected to the backrest portion B312 and extends in a direction substantially perpendicular to the backrest portion B312. The support part B34 moves from the initial state to the standing state according to the movement of the backrest part B312. As shown in FIG. 20A, the support portion B34 is positioned on the side edge side of the seat surface portion B311 with the backrest portion B312 raised. This is the initial state of the support B34. As shown in FIG. 20 (B), when the backrest B312 is in a tilted state (reclining state), the support B34 is erected. This is the standing state of the support portion B34. As the support portion B34 rises, the crus placement portion B33 moves from the retracted position EP to the inspection position IP. The support unit B34 is provided with a light emitting unit B333 that illuminates, for example, a caregiver who performs sample processing by illuminating the outer side of the colonoscopy bed B3.

A crus placement part B33 is connected to the tip of the support part B34 at a substantially right angle to the support part B34. That is, the support portion B34 is off the center of the crus placement portion B33. The crus placement part B33 is a retracted position EP that is a position that does not interfere with insertion of the large intestine endoscope from the anus of the examinee P who is in the lateral position when inserting the large intestine endoscope (FIG. 20A). , (C), (D)) and the examination position IP (see FIG. 20 (B)) that supports the lower leg PA1 of the examinee P in the supine position from below. ing. The lower leg placement section B33 is provided with two recesses B331 for receiving both lower leg PA1 of the examinee P, and a lower leg fixing bar B332 for fixing both lower leg PA1 placed on the recess B331. The crus fixing bar B332 may be detachably provided on the crus placement part B33, or may be rotatably connected.
Note that the lower leg fixing bar B332 is shown only in FIG. 20B for the sake of drawing, and is not shown elsewhere.
The crus placement part B33 is arranged so as to be continuous with the front edge part of the seating surface part B311 and is flush with the main body part B31 in the initial state. The colonoscopy bed B3 in the initial state has a form similar to a chair with a backrest as shown in FIG.
In addition, in this large intestine endoscopic examination bed B3, handrails for preventing inadvertent fluctuations in the posture of the examinee P and supporting the arm of the examinee P are provided on the left and right sides of the backrest B312. It is also possible to provide it.

  In order to prevent the buttocks from sliding down when the backrest B312 falls, the seat surface B311 on which the buttocks rest is reclined together with the support B34 and the crus rest B33. As a result, the examinee P is in the supine position. Thereafter, the seating surface portion 311 returns to the original horizontal position. During upper gastrointestinal endoscopy, since the fiber is inserted from the mouth instead of the anus, the seating surface B311 can be set to remain the seating surface. And as shown in FIG.20 (B), the instrument mounting base B313 is extended from the seat surface part B311, or appeared or protruded from the state stored in the seat surface part B311, and becomes flush with the seat surface part B311. This seat surface part B311 may be stored in the raising / lowering part B32 and replaced with the instrument mounting seat position B313.

Further, the backrest part B312, the lower leg placement part B33, and the support part B34 are seated around the longitudinal axis L of the main body part B31 as shown in FIGS. 20C and 20D with the backrest part B312 lying down. It can rotate to the left and right sides with respect to the surface portion B311.
The above-described series of operations of the colonoscopy bed B3 is also performed automatically by operating a switch provided on the colonoscopy bed B3 or a separate remote control device. .

A procedure for colonoscopy using the colonoscopy bed B3 will be described.
First, the examinee P sits on the colonoscopy bed B3 in the initial state shown in FIG. In this initial state, the backrest B312 is raised, the instrument mounting base B313 is retracted or stored in the seating surface B311, the support B34 is disposed on the side edge side of the seating surface B311, and the crus mounting B33 is in front of the seating surface B311. It arrange | positions so that it may continue to an edge. Therefore, the examinee P can easily put on the colonoscopy bed B3.

  Both the lower leg PA1 of the examinee P sitting on the colonoscopy bed B3 in the initial state enters the two recesses B331 of the lower leg placing part B33. Then, both lower leg PA1 is fixed by the lower leg fixing bar B332. Thus, both the lower leg PA1 of the examinee P follow the movement of the lower leg placing part B33.

  Next, as shown in FIG. 20 (B), the backrest B312 is tilted backward to be substantially horizontal. In conjunction with the movement of the backrest portion B312, the support portion B34 rises, and the crus placement portion B33 moves from the retracted position EP to the examination position IP. When the backrest B312 falls, the seating surface B311 reclines while keeping the same surface as the crus placement part B33 and the support part B34. Thereafter, the seating surface portion B311 returns to the horizontal state. At this time, the instrument mounting table B313 extends from the contracted state, or appears or protrudes from the stored state so as to be flush with the seat surface part B311. The seat surface part B311 is stored in the elevating part B32 and is mounted horizontally. The table B313 may be replaced. At this examination position IP, the examinee P is in the supine position and the lower leg PA1 is supported by the lower leg placement part B33.

  When the colonoscopy bed B3 is also used as an upper gastrointestinal endoscopy bed and used as an upper gastrointestinal endoscopy bed, the seat surface B311 is in a state as a seating surface as it is. 20C, as shown in FIG. 20C, when the backrest B312 is rotated to the left, the examinee P is in the left-side position and can start the upper gastrointestinal endoscopy. When used as an upper gastrointestinal endoscopy bed, an assistant puts the back of the examinee P through the opening B314 provided in the backrest B312.

  Further, the examinee P himself / herself is caused by the backrest B312, the crus placement part B33, and the support part B34 being rotated with respect to the seat surface part B311 about the longitudinal axis L of the main body part B31 (see FIG. 20B). However, the posture of the examinee P can be converted to the lateral position without changing the posture. In addition, since the lower leg PA1 of the examinee P is fixed to the lower leg placement part B33 and does not move carelessly, safety is high. If the upper body of the examinee P is fixed using belts similar to the seat belt of an automobile seat, safety can be further improved.

The posture change is performed in this way, and the examinee P inserts the large intestine endoscope from the anus of the examinee P at the retracted position EP in the left-side prone position shown in FIG. Thereafter, colonoscopy is started.
After the large intestine endoscope is inserted into the examinee P's anus, the large intestine endoscopic examination bed B3 is set to the examination position IP shown in FIG. A colonoscopy is performed by moving the body position automatically or manually to the retracted position EP shown in FIG.

In addition, as shown in FIG. 20B, the instrument mounting table B313 extends, appears, or protrudes from the horizontal seating surface portion B311 to become a horizontal table. The instrument mounting table B313 can be used as a space for placing a colonoscope, which is a long fiber in the colonoscope, and other instruments. Moreover, it is also possible to incorporate a light emitting unit into the instrument mounting table B313.
Further, in the above description, the instrument mounting table B313 is in the seat surface portion B311 and has been described as being flush with the seat surface portion B311 by extending from the contracted state or appearing or protruding from the stored state. However, the instrument mounting table B313 may be rotatably attached to the distal end portion of the seat surface portion B311 and may rise up so as to be flush with the seat surface portion B311. In addition, the instrument mounting table B313 is integrated behind the seat surface portion B311 and can be configured to come out of the seat surface portion B311 by sliding. Alternatively, the instrument mounting table B313 can be configured to emerge from the elevating part B32 and become a horizontal table after the seat surface part B311 is stored in the elevating part B32.

  In addition, it is also possible to use the thing equivalent to the plate-shaped light emission part B25 demonstrated in the large intestine endoscopic examination bed B2 instead of the light emission part B333.

In the above description, the crus placement part B33 is connected to the distal end of the support part B34 at a substantially right angle to the support part B34. However, the present invention is not limited to this. . For example, the crus placement part B33 can be configured to move further forward of the seat surface part B311 by being hinged to the support part B34.
Further, the crus placement part B33 can be configured to be folded in two or configured to be extendable. Further, the crus placement part B33 may be removable from the support part B34, or the crus placement part B33 may be slidably attached to the support part B34. That is, the attachment structure between the crus placement part B33 and the support part B34 may employ any of the attachment structures between the crus placement part and the support part described above.

Next, the colonoscopy bed B4 shown in FIG. 21 will be described.
The large intestine endoscopic examination bed B4 is a large intestine endoscopic examination bed on which the examinee P lies during the large intestine endoscopic examination performed by inserting the large intestine endoscope from the anus. The bed B4 supports a body part B41 on which the examinee P lies, a crus placement part B43 that supports the lower leg PA1 of the examinee P from below, and supports the crus placement part B43 movably with respect to the body part B41. And a support portion B44.

  The body portion B41 includes a seat surface portion B411 on which the buttocks of the examinee P are placed, a backrest portion B412 that receives the back portion of the examinee P, a side receiving portion B415 that is provided on the left side of the left and right sides of the backrest portion B412, It has an instrument placement table B413 for placing a colonoscope or other instrument, which is a long fiber in the endoscope. The bed B4 further includes first and second reclining mechanisms (not shown). By the first reclining mechanism, the seat surface portion B411 and the side surface receiving portion B415 can be tilted with respect to the elevating portion B42, while the side surface receiving portion B415 can be tilted with respect to the seat surface portion B411. By the second reclining mechanism, the backrest portion B412 can be tilted with respect to the side surface receiving portion B415. By tilting the side receiving part B415 and the backrest part B412 respectively, the body position of the examinee P can be converted between the lateral position and the supine position. The main body B41 can be moved up and down by an elevating part B42.

  In the initial state of the colonoscopy bed B4, as shown in FIG. 21A, the backrest part B412 and the side surface receiving part B415 are raised, and the seating surface part B411 is positioned horizontally. The instrument mounting table B413 is folded along the lifting part B42 or stored in the lifting part B42. The backrest portion B412 and the side surface receiving portion B415 are in an orthogonal state.

  Since the backrest B412 is configured such that the left and right edges are raised from the other parts, it is possible to fix the upper body of the examinee P (however, for the convenience of drawing, the left and right edges Is not shown in the figure.) In addition, when it is necessary to more firmly fix the upper body of the examinee P, it is possible to fix the belt using belts similar to the seat belts of automobile seats.

The support portion B44 has a base end portion connected to the side surface receiving portion B415 and extends in a direction perpendicular to the side surface receiving portion B415. The support portion B44 moves from the initial state to the standing state according to the movement of the side surface receiving portion B415. As shown in FIG. 21A, the support portion B44 is positioned on the front edge side of the seat surface portion B411 in a state where the side surface receiving portion B415 is raised. This is the initial state of the support B44. As shown in FIG. 21 (B), when the side surface receiving portion B415 is in a tilted state (reclining state), the support portion B44 is erected. This is the standing state of the support portion B44.
The support unit B44 is provided with a light emitting unit B443 that illuminates, for example, a caregiver who performs sample processing by illuminating the outer side of the colonoscopy bed B4.
In addition, a substantially concave letter-shaped lower limb receiving portion B416 is provided on the lower end side of the side surface receiving portion B415. The lower limb receiving portion B416 receives the lower limb PA of the examinee P in the left-side prone position, extends in the length direction of the side receiving portion B415, and is flush with the side receiving portion B415. In a state where the side surface receiving portion B415 is flush with the seating surface portion B411, the lower limb receiving portion B416 is positioned on the same plane as the seating surface portion B411.

A crus placement part B43 is connected to the front end of the support part B44 at a substantially right angle to the support part B44. That is, the support portion B44 is off the center of the crus placement portion B43. The crus placement part B43 is arranged so as to continue to the front edge part of the seat surface part B411 in the initial state. Therefore, the colonoscopy bed B4 in the initial state has a form similar to a chair with a backrest as shown in FIG. As shown in FIG. 21B, the crus placement part B43 stands together with the support part B44 from the initial state. The crus placement part B43 stands up, and the state along the longitudinal direction of the side surface receiving part B415 becomes the retreat position EP. The retracted position EP is a position that does not interfere with the insertion of the large intestine endoscope from the anus of the examinee P who is in the lateral position when inserting the large intestine endoscope. As the support portion B44 rotates in the standing state, the crus placement portion B43 moves from the retracted position EP in the direction crossing the side surface receiving portion B415 as shown in FIG. 21C, and is positioned at the inspection position IP. As shown in FIG. 21C, the examination position IP is a position where the lower leg PA1 of the examinee P who is in the supine position can be supported from below.
The lower leg placement section B43 is provided with two recesses B431 for receiving both lower leg PA1 of the examinee P, and a lower leg fixing bar B432 for fixing both lower leg PA1 placed on the recess B431. The crus fixing bar B432 may be detachably provided on the crus placement part B43, or may be rotatably connected.
Note that the lower leg fixing bar B432 is shown only in FIG. 21B for the sake of drawing, and is not shown elsewhere.
The colonoscopy bed B4 has a hand for preventing inadvertent fluctuations in the posture of the examinee P on the side receiving portion B415 and the backrest B412 and for supporting the arm of the examinee P. It is also possible to provide a slide.

  The backrest B412 is connected to the side receiving part B415 at the left edge. The backrest B412 can be tilted (opened) so as to be flush with the side receiving part B415 in a state where the side receiving part B415 is collapsed.

  The above-described series of operations of the colonoscopy bed B4 is also performed automatically by operating a switch provided on the colonoscopy bed B4 or a separate remote control device. .

A procedure for colonoscopy using the colonoscopy bed B4 will be described.
First, the examinee P sits on the colonoscopy bed B4 in the initial state shown in FIG. 21A with the backrest B412 as a backrest. In the initial state of the colonoscopy bed B4, the backrest part B412 and the side surface receiving part B415 are raised, the instrument mounting table B413 is folded or stored in the elevating part B42, and the crus mounting part B43 is the seating surface part B411. It arrange | positions so that it may continue to a horizontal edge part. Thus, the examinee P can easily place it on the colonoscopy bed B4.

  The examinee P leans on the side receiving part B415. From this state, the side receiving part B415 falls toward the left side of the examinee P. At this time, since the backrest portion B412 is in a direction orthogonal to the side surface receiving portion B415, the examinee P falls to the left lateral direction while facing the same direction as when sitting. At this time, the seat surface portion B411 tilts together with the side surface receiving portion B415 in a state orthogonal to the side surface receiving portion B415 so that the collar portion does not slide down. When the side receiving part B415 falls down, the posture of the examinee P naturally becomes the left side prone position. At this time, the support part B44 and the lower leg placing part B43 stand up with the inclination of the side face receiving part B415, and the lower leg receiving part B416 becomes horizontal.

Thereafter, as shown in FIG. 21B, the seat surface portion B411 tilts with respect to the side surface receiving portion B415 and returns to the horizontal. At this time, the seat surface portion B411 forms the same horizontal plane as the instrument mounting table B413 that emerges from the seat surface portion B411, or the seat surface portion B411 is stored in the lift unit B42, and the instrument mount table B413 appears from the lift unit B42 and is replaced. Or you may. Thus, there is the crus placement part B43 at the retracted position EP, and the examinee P is in the left lateral position, so that the colonoscopy can be started.
When this colonoscopy bed B4 is also used as the upper gastrointestinal endoscopy bed, the upper gastrointestinal endoscopy can be started in the left-side position. In the upper gastrointestinal endoscopy, since the fiber is inserted from the mouth instead of the anus, the seating surface portion B411 can be set so that the seating surface can be left as it is.

Next, in order to change from the left-side prone position to the supine position, the backrest part B412 is tilted with respect to the side surface receiving part B415 (opening the backrest part B412) and flush with the side surface receiving part B415. Along with this operation, the examinee P changes from the supine position to the supine position.
Simultaneously with or after this, the support part B44 is rotated to move the crus placement part B43 from the retracted position EP to the inspection position IP. Then, both the lower leg PA1 of the examinee P who is in the supine position is placed on the two recesses B431 of the lower leg placing part B43 at the examination position IP. Then, both lower leg PA1 is fixed to the lower leg placing part B43 by the lower leg fixing bar B432.

The instrument mounting table B413 is flush with the seating surface part B411 at an appropriate time. If it does not interfere with the colonoscopy, it should be flush with the seat B411 from the time the examinee P sits on the colonoscopy bed B4 in a form similar to a chair with a backrest. Is also possible.
In addition, this instrument mounting base B413 can be used as a space for placing a large intestine endoscope, which is a long fiber in the large intestine endoscope, and other instruments. Moreover, it is also possible to incorporate a light emitting unit into the instrument mounting table B413.

In the above description, the crus placement part B43 is connected to the distal end side of the support part B44 at a substantially right angle to the support part B44. However, the present invention is not limited to this. . For example, the crus placement part B43 can be configured to move further forward of the seat surface part B411 by being hinged to the support part B44.
Further, the crus placement part B43 can be configured to be foldable in two or configured to be extendable. The crus placement part B43 may be removable from the support part B44, or the crus placement part B43 may be slidably attached to the support part B44. That is, the attachment structure between the crus placement part B43 and the support part B44 may employ any of the attachment structures between the crus placement part and the support part described above.

In the colonoscopy beds B3 and B4 described above, the instrument mounting bases B313 and B413 are incorporated in the seating surface portions B311 and B411, and the seating surface portions B311 and B411 are configured to come out when necessary. Is bent downward at the tip end side, and becomes substantially horizontal when necessary to be flush with the seating surface portions B311 and B411, or is integrated behind the seating surface portions B311 and B411. Although it is configured to come out by sliding, it goes without saying that other configurations may be used.
For example, when the lower leg PA1 is supported in the supine position by the lower leg placement parts B33 and B43, the seat surface parts B311 and B411 are lowered downward, and the instrument placement bases B313 and B413 are at positions where the seat surface parts B311 and B411 were originally located. Further, it may be configured to come out from the backrest parts B312, B412 and the lifting parts B32, B42.

  These operations may be performed manually or via a switch provided in the colonoscopy bed B3, B4 or a separate remote control device. As a separate remote control device, from the viewpoint that the operation of the remote control device does not hinder the colonoscopy by the doctor D, the stepping type connected to the colonoscopy beds B3 and B4 by wire or wirelessly The foot switch is desirable. It should be noted that at least the base end side portion of the support portion may be located at a position away from the center of the crus placement portion at the inspection position.

  As long as it has the following configuration, the design of the crus table for colonoscopy of the present invention can be arbitrarily changed. The lower leg mounting table for colonoscopy includes a base part, a lower leg mounting part that can support the examinee's lower leg from below, and a support part. The support portion is provided on the base portion and supports the crus placement portion movably from the inspection position to the retracted position. Alternatively, the support part is provided on the base part so as to support the crus placement part and to be movable together with the crus placement part from the inspection position to the retracted position. The examination position is a position where the examinee's lower leg where the lower leg placing part is in the supine position can be supported from below. The retracted position is a position that does not interfere with the insertion of the large intestine endoscope from the anus of the examinee in which the lower leg placing portion is in the lateral position. The bed of the present invention includes the above-described crus mounting table for colonoscopy, and the design can be arbitrarily changed as long as the base portion is the main body portion of the bed. The light emitting part of the present invention can be arbitrarily changed in design as long as it is provided on the support part, the base part or the crus rest part so that light can be emitted in a direction away from the bed.
