DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of an endoscope processing support device according to the present invention will be described in detail with reference to the drawings.
[0029]
(1) First embodiment
FIG. 1 is a diagram showing a configuration and an operation of an endoscope processor according to a first embodiment of the present invention. FIG. 1 (A) is a side view showing the configuration, and FIG. 1 (B) is a diagram during normal use. FIG. 1C shows a partially enlarged sectional view showing a state, and FIG. 1C shows a partially enlarged sectional view showing a state during cleaning.
[0030]
As shown in the figure, the endoscope processor 4A has a box-shaped housing 40A, and includes the same components as those incorporated in the conventional endoscope processor 4 ′ described above. Instead of the ventilation hole 45 ', a ventilation part 45A is provided on the side plate 44A.
[0031]
As shown in FIGS. 1A to 1C, the ventilation portion 45A includes a plurality of substantially cylindrical first holes 440A provided in the side plate 44A of the housing 40A and the inner side of the side plate 44A. And a substantially flat sliding member 451A having a plurality of substantially cylindrical second holes 450A, and a substantially central upper portion of the sliding member 451A for driving the sliding member 451A. There is a projecting drive lever 452A, and a horizontally elongated regulation hole 441A which is provided on the side plate 44A and engages with the drive lever 452A to regulate the movement direction of the drive lever 452A in the horizontal direction of FIG. is doing. Further, the first hole 440A and the second hole 450A have cross sections that can communicate with each other, for example, the same shape cross section.
[0032]
Next, the operation of the endoscope processor 4A of this embodiment will be described.
First, as shown in FIG. 1A, in a state where the drive lever 452A is positioned at the center of the restriction hole 441A, as shown in the cross-sectional view of FIG. 1B, the first lever 440A of the side plate 44A slides. The second hole 450A of the moving member 451A communicates with each other, and the ventilation portion 45A is open. Therefore, external air can flow into the housing 40A, and air for cooling such as the light source 46 (see FIG. 4B) can be taken into the housing 40A.
[0033]
In this case, FIGS. 1B and 1C show the side plate 44A and the sliding member 451A as viewed from above in FIG. 1A, and FIG. 1B and FIG. The vertical direction in C) is the horizontal direction in FIG.
[0034]
Next, when the operator holds the drive lever 452A by hand and performs a drive operation to either side of the left and right ends of the restriction hole 441A, the sliding member 451A moves up and down in the figure as shown in FIG. Move in one of the directions. As a result of this operation, the sliding member 451A, which is disposed in close contact with the back surface of the side plate 44A, slides on the back side of the side plate 44A.
[0035]
Therefore, in the state of FIG. 1B, the first hole 440A and the second hole 450A are attached to the inside of a substantially cylindrical long hole (hereinafter referred to as “communication hole”) formed by communication. Among the dust, the one having the center of gravity outside the boundary line between the side plate 44A and the sliding member 451A (side plate 44A) is pushed out of the hole by the above sliding operation. Then, it falls out of the housing 40A.
[0036]
On the other hand, among the dust adhering to the inside of the communication hole, the one having the center of gravity on the inner side (sliding member 451A side) of the boundary line between the side plate 44A and the sliding member 451A It is pushed out toward the inside of the hole by the moving operation, and falls into the housing 40A.
[0037]
That is, in the case of the endoscope processor 4A of the present embodiment, of the dust adhering to the inside of the communication hole, approximately half of the outer side falls outside, and almost half of the inner side falls outside. become.
[0038]
Due to the pushing action that accompanies the sliding operation, it is possible to prevent clogging caused by accumulation of dust or the like in the communication hole.
[0039]
The endoscope processor of this embodiment can take a further improved configuration. FIG. 1D is a partial enlarged cross-sectional view illustrating a configuration of a variation of the ventilation portion of the present embodiment.
As shown in the figure, the endoscope processor 4B has the same configuration as the endoscope processor 4A described above except for the configuration of the first hole and the second hole. That is, in the endoscope processor 4B, the first hole 440B is a through hole formed in the side plate 44B, and has a substantially truncated cone-like cross-sectional shape whose diameter increases toward the outside of the housing 40B. ing. The second hole 450B is a through-hole formed in the sliding member 451B, and has a substantially frustoconical cross-sectional shape whose diameter increases toward the outside of the housing 40B. And the cross section of the inner side edge part of the 1st hole 440B and the cross section of the outer side edge part of the 2nd hole are substantially corresponded, and both are connecting.
[0040]
With this configuration, first, in a state where the drive lever (not shown) is located at the center of the restriction hole (not shown), as shown in the sectional view of FIG. Thus, the communication hole is formed, and the ventilation portion 45B is open. Accordingly, external air can flow into the housing 40B, and air for cooling such as the light source 46 (see FIG. 4B) can be taken into the housing 40B.
[0041]
Next, when the operator manually operates a drive lever (not shown) and drives the left or right end of the restriction hole (not shown), the sliding member 451B moves in the vertical direction in the figure. Move to one of the following. As a result of this operation, the sliding member 451B disposed substantially in close contact with the back surface of the side plate 44B slides on the back side of the side plate 44B.
[0042]
Accordingly, in the state of FIG. 1D, among the dust adhering to the inside of the hole (hereinafter referred to as “communication hole”) formed by communicating the first hole 440B and the second hole 450B. The center of gravity is located on the outer side (side plate 44B side) of the boundary line between the side plate 44B and the sliding member 451B, and the center of gravity position is located on the inner side (sliding member 451B side) of the boundary line. A considerable part of the structure is guided toward the outside of the hole by the above-described sliding operation and the interaction between the inclined inner wall of the first hole 440B and the inclined inner wall of the second hole 450B. It will fall out to the outside.
[0043]
On the other hand, the dust falling into the inside of the housing 40B is only a part of the dust adhering to the inside of the communication hole, and is further inside (sliding) than the boundary line between the side plate 44B and the sliding member 451B. This corresponds to the case where the center of gravity is located near the inner edge of the second hole 450B, in particular, on the moving member 451B side. Such dust is pushed out toward the inside of the hole in accordance with the above sliding operation, and drops into the housing 40B.
[0044]
That is, in the case of the endoscope processor 4B of this variation, more than half of the dust that has adhered to the inside of the communication hole, for example, about 70 to 80%, drops off to the outside, About 20 to 30% will fall out to the inside.
[0045]
According to the venting portion 45B of the endoscope processor 4B of this variation due to the pushing action associated with the sliding operation, dust or the like accumulates in the communication hole and causes clogging. It can be prevented in the same way as in the case. Moreover, the dust accumulated in the communication hole can be dropped to the outside more effectively than in the case of the ventilation portion 45A. When dust falls inside the housing, it accumulates inside the housing and cannot be removed unless the upper half of the housing is opened. Therefore, it is preferable to drop the dust outside the housing.
[0046]
As an example of the change of the endoscope processor 4B described above, the configuration of the second hole 450B may be changed to the configuration of the first hole while leaving the hole having a substantially truncated cone shape as shown in FIG. Is possible. For example, the first hole may be a substantially cylindrical hole. Even with such a configuration, the dust accumulated in the communication hole can be dropped to the outside more effectively than in the case of the ventilation portion 45A. That is, it is sufficient that at least the second hole has a cross-sectional shape whose diameter increases toward the outside of the housing.
[0047]
The endoscope processor according to the present embodiment may further have a configuration other than that described above. FIG. 1E is a partial enlarged cross-sectional view showing the configuration of another variation of the ventilation portion of the present embodiment.
As shown in the figure, the endoscope processor 4C is configured such that the side plate and the sliding member are inclined with respect to the vertical plane, and the upper portion protrudes from the lower portion. Except for the above-described configuration of the endoscope processor 4A. In other words, in the endoscope processor 4C, the first hole 440C is a through hole formed in the side plate 44C inclined by a predetermined angle with respect to the vertical plane, and is formed in a substantially cylindrical shape. The second hole 450C is a through hole provided in the sliding member 451C disposed in close contact with the back surface of the side plate 44C, and is formed in a substantially cylindrical shape. And the cross section of the inner side edge part of 440C of 1st holes and the cross section of the outer side edge part of 2nd hole are substantially corresponded, and both are connecting. Further, as shown in FIG. 1E, the first hole 440C and the second hole 450C have an inclination that descends from the inside of the housing toward the outside of the housing.
[0048]
In this case, FIG. 1E shows the side plate 44C and the sliding member 451C as viewed from any of the horizontal directions in FIG. 1A, and the vertical direction in FIG. 1 (A) in the vertical direction.
[0049]
With this configuration, first, in a state where the drive lever (not shown) is located at the center of the restriction hole (not shown), the two communicate with each other as shown in the sectional view of FIG. Thus, the communication hole is formed, and the ventilation portion 45C is open. Therefore, external air can flow into the housing 40C, and air for cooling such as the light source 46 (see FIG. 4B) can be taken into the housing 40C.
[0050]
Next, when the operator manually operates a drive lever (not shown) and drives to either side of the right and left ends of the restriction hole (not shown), the sliding member 451C is moved to the paper surface in the drawing. It moves in either the direction from the front to the back or the direction from the back to the front of the page. As a result of this operation, the sliding member 451C disposed substantially closely to the back surface of the side surface plate 44C moves the back surface side of the side surface plate 44C from the front side to the back side in the drawing or from the back side to the front side in the drawing. Slide in either direction.
[0051]
Therefore, in the state of FIG. 1E, a substantially cylindrical long hole (hereinafter referred to as “communication hole”) formed by the communication between the first hole 440C and the second hole 450C is the inside of the housing. Most of the dust adhering to the inside of the communication hole is the above-mentioned sliding operation and the casing of the first hole 440C. The inner wall inclined toward the outside and the inner wall inclined toward the outside of the housing of the second hole 450C are guided to fall outside the hole and fall out of the housing 40C.
[0052]
According to the venting portion 45C of the endoscope processor 4C of this variation due to the pushing and falling action associated with the above sliding operation, the above-described venting portion causes dust and the like to accumulate in the communication hole and cause clogging. This can be prevented in the same manner as in the case of 45A. Moreover, the dust accumulated in the communication hole can be dropped to the outside more effectively than in the case of the ventilation portion 45A.
[0053]
As a variation of the endoscope processor 4C described above, it is possible to further increase the degree of inclination of the first hole and the second hole that descend toward the outside of the housing. With such a configuration, the dust accumulated in the communication hole can be dropped to the outside more effectively than in the case of the ventilation portion 45C described above.
From the above, it is considered that the side plate and the sliding member may be vertical as long as the first hole and the second hole are inclined so as to descend toward the outside of the casing. .
[0054]
(2) Second embodiment
Next, a second embodiment of the present invention will be described.
2A and 2B are diagrams showing the configuration and operation of an endoscope processor according to the second embodiment of the present invention. FIG. 2A is a perspective view showing the overall configuration, and FIG. Sectional drawing which shows the further detailed structure of each is shown.
[0055]
As shown in the figure, the endoscope processor 4D has a box-shaped casing 40B, and includes the same components as those included in the conventional endoscope processor 4 ′ described above. Instead of the ventilation hole 45 ', a ventilation part 45D is provided on the side plate 44D, and an adsorption preventing member 51 is provided in the vicinity of the ventilation part 44D.
[0056]
As shown in FIGS. 2A and 2B, the ventilation portion 45D described above is substantially in close contact with the plurality of first holes 440D formed in the side plate 44D of the housing 40D and the inside of the side plate 44D. And a substantially flat sliding member 451D having a plurality of second holes 450D and a drive lever (not shown) for driving the sliding member 451D. Further, the first hole 440D and the second hole 450D have cross sections that can communicate with each other, for example, the same cross section. Since the detailed configuration and operation of these components are the same as those of the components in the ventilation portions 45A to 45C described above, description thereof is omitted.
[0057]
The above-described adsorption preventing member 51 is a substantially lattice frame-shaped member made of a plate material or the like, and is disposed on the outer side of the first hole 440D so as to surround the first hole 440D. Further, a third hole 52 having a substantially horizontally long slit shape is formed in the side wall portion of the adsorption preventing member 51.
[0058]
Next, the operation of the endoscope processor 4D of this embodiment will be described.
First, the above-described endoscope processor 4A is described with respect to the action of dropping dust or the like accumulated inside the first hole 440D and the second hole 450D to the outside or inside of the housing by reciprocating sliding of the sliding member 451D. It is exactly the same as in the case of ~ 4C.
[0059]
In the case of the endoscope processor 4D of the present embodiment, in addition to the above-described operation, when a thin-film or sheet-like member such as paper or cloth is sucked by the air flow sucked into the vent hole portion, Such a thin film-like member is adsorbed by the end face of the frame, and the air intake is performed by the third hole 52 provided in the side wall as shown by A in FIG. is doing. In this way, it is possible to effectively prevent such a situation that the thin film-like member is adsorbed by the vent hole portion and obstructs the intake of air into the housing.
[0060]
In the above-described embodiments, the endoscope processors 4A to 4D correspond to an endoscope processing support device. The blower fan 47 corresponds to a blower. The surfaces of the side plates 44A to 44D of the housing correspond to the first surface. The drive lever 452A provided on the sliding member 451A, the restriction hole 451A provided on the side plate, and the like constitute drive means.
[0061]
The present invention is not limited to the above embodiments. Each of the embodiments described above is an exemplification, and any configuration that has substantially the same configuration as the technical idea described in the claims of the present invention and has the same operational effects can be used. It is included in the technical scope of the present invention.
[0062]
For example, in each of the above-described embodiments, the example in which the first hole is provided in the side plate of the housing and the sliding member is provided on the inner side of the side plate has been described, but the present invention is not limited to this. Other configurations, for example, those in which the first hole is provided in the top plate of the casing, or those in which the first hole is provided in the rear plate of the casing, or the first hole in the bottom plate of the casing It may be provided in the above. Furthermore, the sliding member may be provided in another configuration, for example, on the outside of the housing.
[0063]
Further, in each of the above embodiments, as a driving means for driving the sliding member, a combination of a driving lever provided in the sliding member and a restriction hole provided in the side plate has been described as an example. This invention is not limited to this, You may use the drive means which consists of another structure, for example, a well-known drive source and a power transmission mechanism. Examples of such a drive source include a solenoid and an electric motor. Examples of the power transmission mechanism include a reciprocating motion generating mechanism such as a cam, a rack and pinion, a screw mechanism, and a crank mechanism.
Further, the driving direction of the sliding member may be other than the reciprocating direction. For example, the sliding member may be configured to be rotatable around the rotation axis and may be configured to slide in the rotation direction.
Also, the drive control of the sliding member may be a method other than the method using the operator's human power as in the present invention, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). Program control may be performed by an ultra-compact processing arithmetic unit) or the like.
Further, the control timing may be slid when the power is turned on. In the case of the sliding at the time of turning on the power, the sliding may be performed by a known mechanism using the human power for the power-on operation. Alternatively, sliding may be performed by delaying the power-off for a predetermined time at the time of power-off. Alternatively, control may be performed so that the sliding operation is performed by detecting a time point when a predetermined period has elapsed from the previous sliding operation using a timer or the like.
[0064]
Further, the sliding member described above may be provided with means for assisting sliding and operations accompanying it. For example, a spring or the like that biases the sliding member in any of the sliding directions may be attached to the sliding member. In this way, as a manual operation, it is only necessary to drive in one of the sliding directions, and if the hand is loosened, it automatically returns to its original position by the biasing force of a spring or the like, making reciprocating sliding easier. Become.
Alternatively, in the embodiment of FIG. 1, the click lever may be configured to stop when the drive lever reaches the center position of the restriction hole. In this way, there is no need to visually confirm the communication between the first hole and the second hole.
Further, even when the sliding member is moved in the maximum sliding direction, the first hole and the second hole may always be partially communicated so that they are not completely closed. In this way, the first hole and the second hole are not completely closed as shown in FIG. 1C, and the first hole is caused by the forgottenness of the operator during the sliding operation. And it is possible to prevent the situation where the endoscope processing support apparatus is used with the second hole closed.
[0065]
In the above-described second embodiment, the substantially lattice frame-like member has been described as an example of the adsorption preventing member. However, the present invention is not limited to this, and other configurations, for example, the first surface In addition, it may be provided with a substantially flat plate shape, a substantially rectangular parallelepiped shape, a substantially disk shape, a substantially columnar shape, or the like, and a side surface made of a net-like member. Alternatively, even if the opening edge of a specific one of the plurality of first holes is protruded and the thin film-like member is sucked, it is adsorbed at the opening edge of the specific first hole, and air intake is performed in the other first hole. You may do it. Accordingly, it is sufficient that the adsorption preventing member is disposed on the outer side of the first hole and in the vicinity of at least a part of the first hole.
[0066]
【The invention's effect】
As described above, according to the endoscope processing support apparatus according to the present invention, the first hole that is opened in the first surface of the housing and takes in air, the second hole that communicates with the first hole, Since the sliding member disposed substantially in close contact with one hole and the driving means for driving the sliding member are provided, it is possible to prevent dust and the like from accumulating in the vent hole portion.
Further, in the above, even when a thin film member or the like is adsorbed to the vent hole portion by disposing the adsorption preventing member on the outside of the first hole and opening the third hole in the side wall portion of the adsorption preventing member. There is also an advantage that air can be taken into the housing without any trouble.
