Installation step to endoscope plug body 1 describes.At first, plunger member 20 is held and be configured in the plunger member of plug frame 30 with in the 37b of inner space.At this moment, plunger member 20 strains.In addition, in the maintenance of plunger member 20 with on the inclined-plane 24, the plunger member protuberance 38a of butt plug frame 30, can prevent plunger member 20 from plunger member with coming off in the 37b of inner space.

Then, the ring portion 14 of cover 10 is pressed into is configured in the ring installation portion that constitutes by the 1st flange 44a and the 2nd flange 44b.Then, shown in Fig. 3 waits, be embedded among the lid main body mounting groove 35a on the cover installation portion 35 that is arranged on plug frame 30 being arranged on all shape jut 11b on the lid main part 11 of cover 10.By these steps, can be assembled into endoscope plug body shown in Figure 71.The endoscope plug body 1 of the state that has assembled like this is provided to the user.

Then, the installation to access portal portion 3 describes to endoscope plug body 1.For endoscope plug body 1 is installed in the access portal portion 3, make the open side of conduct one end of the plug main body 31 of filling in frame 30, be engaged on the joint 3a from the engaging direction of stipulating, to cover joint 3a.So the joint holding section 38b and each thinner wall section 41 that are arranged on the plug main body 31 are crossed flange part 3d in strain.Thereby joint holding section 38b is stuck and is configured on the flange part 3d under the state that is adjacent to flange part 3d.At this moment, set joint 3a at joint in space 37c, the interior lateral incline 3b butt of joint 3a is incorporated in the front end inclined-plane 22a of plunger member with the plunger member 20 in the 37b of inner space.So, make plunger member 20 move to top board face 37a side, bottom surface sections 21 becomes the state that is adjacent to top board face 37a, and simultaneously, interior lateral incline 3b and front end inclined-plane 22a become proximate state.Thereby endoscope plug body 1 remains watertight/gastight state with outside and access portal portion 3.

And, under this sets state, by the plunger member outer lateral incline 3c of protuberance 38a butt, be applied in the loading as swing under the situation of plug main body 31, because flange part 3d is gripped with protuberance 38a and joint holding section 38b by plunger member, the state that endoscope plug body 1 is installed in the access portal portion 3 keeps stable.In other words, be applied in the loading as swing under the situation of plug main body 31, plug frame 30 is provided in the access portal portion 3 with being difficult to topple over.

In addition, under the state that endoscope plug body 1 is installed in the access portal portion 3, when treatment apparatus 9 grades are inserted when logical, treatment apparatus 9 is directed in the access portal portion 3 by hemispherical recesses 11a, narrow slit 15, circular hole 23a.Insert under the logical state at this treatment apparatus, the inner peripheral surface of circular hole 23a becomes the state of the outer peripheral face that roughly is adjacent to treatment apparatus 9 by the elastic force that plunger member 20 has.And the elastic force that the inner peripheral surface of narrow slit 15 also has by cover 10 becomes the state that its part is adjacent to the outer peripheral face of treatment apparatus 9.That is, by endoscope plug body 1, under the state in treatment apparatus 9 is directed to access portal portion 3, the inner peripheral surface of the part of the inner peripheral surface of narrow slit 15 and circular hole 23a becomes the state of the outer peripheral face that is adjacent to treatment apparatus 9.Thereby endoscope plug body 1 can prevent that being inserted under the state of logical treatment apparatus 9 by this endoscope plug body 1 body fluid or dirt from dispersing to the outside.

And, insert under the situation of leading in the endoscope plug body 1 at the treatment apparatus that external diameter is thicker, make the lid main part 11 of cover 10 become the state that unloads from the cover installation portion 35 of plug frame 30, also can insert logical treatment apparatus.Thereby being used for inserting the slotting concerted effort of leading to treatment apparatus can reduce.And the elastic force that the inner peripheral surface of circular hole 23a utilizes plunger member 20 to have by being adjacent to the outer peripheral face of treatment apparatus, can keep watertight/airtight conditions.

Then, the dismounting from access portal portion 3 describes to endoscope plug body 1.When dismounting is installed in endoscope plug body 1 in the access portal portion 3, keep plug frame 30 along Zhou Fangxiang continuum of states on one side, destroy the part of endoscope plug body 1 on one side, specifically, broken ring is as the plug main body destruction 31a of portion of the part of plug main body 31.At this moment, as shown in figure 10, the user for example make forefinger be placed on jut 32 grip part 32a above.At this moment, become in tang portion 12 under the situation of obstruction, mention this tang portion 12 with nail-side and move it.And then, jut 32 is applied downward loading shown in arrow F1, in other words, jut 32 is applied the loading of direction when the engaging endoscope plug body 1 (, make plug frame 30 cover the direction of joint 3a).So the loading of jut 32 by applying is fulcrum with the contact portion of joint holding section 38b and flange part 3d (for example, the part of the flange part 3d of contact joint holding section 38b), rotates along the direction shown in the arrow a.At this moment, near 2nd thinner wall section 42 and 1st thinner wall section 41 of stress concentration jut 32 that produces by jut 32.Because joint 3a is a metallic, so rigidity is very high.Thereby the flange part 3d of joint 3a can not collapse, and can prevent that detent plug main body 31 crushes in the inboard, can prevent that loading from disperseing.

And by the stress that is produced by jut 32, at first, the 2nd thinner wall section 42 of top sidepiece that is arranged on this jut 32 is destroyed.Then, to be arranged on the 1st thinner wall section 41 of plug main body destruction portion 31a both sides integratedly destroyed from the 2nd thinner wall section 42 sides with jut 32.At this moment, the plug main body destruction 31a of portion with jut 32 is provided with integratedly can not separate on plug main body 31 fully, that is, the part of the plug main body destruction 31a of portion still keeps being connected with plug main body 31 state of ormal weight.Thereby as shown in figure 11, as the apparent collapse state of plug main body 31, the root portion 32b that becomes jut 32 is by the state after fractureing.This collapse state is called the 1st collapse state.

After the 1st destruction, as shown in Figure 12 and Figure 13, the user for example uses the grip part 32a of thumb and forefinger grip knob portion 32.And then, apply oblique below loading shown in arrow F2 to jut 32.So, not destroyed complete destructive the 1st thinner wall section 41 and destroyed fully by the 1st, the plug main body destruction 31a of portion becomes from plug main body 31 complete separated destructive destruction completion statuses with jut 32.This collapse state is called the 2nd collapse state.Here, jut 32 plays the function as operating portion as mentioned above, and it separates the fracture operation of rupture the 1st thinner wall section 41 and the 2nd thinner wall section 42 in order to make the plug main body destruction 31a of portion from plug main body 31.By operating such jut 32, the 1st thinner wall section 41 that ruptures and the 2nd thinner wall section 42, to fill in the main body destruction 31a of portion and separate, divide by local failure thereby card ends the fastener of the joint holding section 38b on flange part 3d from plug frame 30 (specifically, plug main body 31).In the case, owing to fill in frame 30 along the successive zone of this Zhou Fangxiang, for example cover installation portion 35, keeping does not have ruined state, therefore, keeps along this Zhou Fangxiang continuum of states.Like this, under the Zhou Fangxiang continuum of states of edge plug frame 30, for example, cover installation portion 35 suppresses the expansion of the barrel shape of plug frames 30.When the 2nd collapse state, plug main body destruction 31a of portion and jut 32 also keep being installed in the state in the access portal portion 3 from the endoscope plug body 1 of plug main body 31 isolating states.In the case,, therefore, can keep the barrel shape that is installed in dismantledly on the joint 3a, can prevent from unconsciously to come off from joint 3a because the plug frame 30 of described the 2nd collapse state remains on along its all direction continuum of states.In addition, since towards access portal portion 3 (that is, making the direction of plug frame 30 contact joint 3a) stretching jut 32 with its destruction, therefore, therefore plug main body 31 can or not come off to being applied in power from access portal portion 3 isolating directions (that is, the direction of extracting from joint 3a).

Unload endoscope plug body 1 under the state that is installed in access portal portion 3 herein.At this moment, the plug main body destruction 31a of portion separates from plug main body 31, and simultaneously, by on plug main body 31 a plurality of the 1st thinner wall section 41 being set, plug frame 30 can make the barrel shape distortion, comes so that can break away from from joint 3a.Thereby endoscope plug body 1 can end state by the card that user's hands is easily removed between plug frame 30 and the joint 3a, can unload from access portal portion 3 very swimmingly.

Like this, in the part of the plug main body that in the plug frame that constitutes endoscope plug body, has, be provided with plug main body destruction portion, it weakens being constituted by fracture portion of fracture strength by thinner wall section etc. is set, simultaneously, and by jut is set in this plug main body destruction portion, by this jut is carried out suitable operation, only, endoscope plug body is come off from access portal portion, plug main body destruction portion is separated from the plug main body with very little strength.

Thereby the hands that can pass through the user unloads the isolating endoscope plug body of a part of filling in main body swimmingly from access portal portion.In addition, as the ruined situation of plug main body destruction portion of a plug main body part, can be from differentiating in appearance, can prevent the operation mistake that used endoscope plug body is used mistakenly once more reliably.Thereby, can brand-new endoscope-use plug frame be installed in the access portal portion according to each disease.

In addition, owing to jut is applied the loading of pushing towards the below, in other words, make finger move to the operating portion side of endoscope, the part of plug main body is destroyed by 1 time, therefore, removed quickly in the loading of finger tip, under the situation that finger breaks away from from jut, can prevent finger take advantage of a situation run into around.

And then, owing to be that the plug main body destruction portion that will be arranged on the framework carries out destructive structure by 2 stages of the 1st collapse state and the 2nd collapse state, therefore, destroy the moment of finishing at described 1 time that applies very big loading, because jut also is being connected with the plug main body, therefore, can prevent from only to make jut to fall.

In addition,, therefore, in the 2nd collapse state, make the plug main body become the state that roughly keeps as the original shape of structure, it is remained in the access portal portion owing to only destroy a part of side of plug main body.Thereby plunger member that can prevent to be attached with body fluid or dirt etc. comes off, and can wholesomely carry out operation.

In addition, constitute pyramid shape, can make up and down clamping of finger by grip part with jut, or about the jut that stretches clampingly, therefore, apply loading easily, can easily carry out 2 times and destroy.

And, by thumb is placed on the jut, other finger is placed on the operating portion of endoscope and keeps, also can destroy operation, in this case,, therefore, can improve operation owing to just can destroy operation with a hands.

In addition, because therefore jut, can only be downwards the action of access portal direction along outstanding upward setting of direction of lid, can not be to cock body is applied power from the direction that access portal breaks away from.

And then, endoscope plug body is constituted as shown in Figure 14.Figure 14 is the axonometric chart that schematically shows as the outward appearance of the endoscope plug body of the variation 1 of the 1st embodiment of the present invention.Use among the cock body 1A at this medical endoscope shown in Figure 14, the cover mounting portion among the plug frame 30A and the ring portion structure of cover are different with above-mentioned structure.That is, as shown in the figure, the bottom, side at the opposition side of the side that is formed with jut 32 of the plug frame 30A of endoscope plug body 1A is formed with the arrowhead form portion 46 as fitting portion.Arrowhead form portion 46 forms quadrangular, and this quadrangular square in shape near base end side, forms greatly more along with more, and base end side is elongated on the contrary.Be formed with par 17 on cover 10A, it is the cardinal extremity sidepiece with connecting portion 13 one.17 substantial middle is formed with and the equal big or small square hole 17a of quadrangular in the par, and square hole 17a becomes installment state after arrowhead form portion 46 strains.On the plug main body 31 of plug frame 30A, unlike the 1st embodiment, to distinguish the 1st flange 44a and the 2nd flange 44b, but form a flange part 44c.Other structure is identical with above-mentioned the 1st embodiment, gives prosign to same parts, and omits its explanation.

Like this, owing on cover 10A, do not have ring portion, therefore, by automat assembling endoscope plug body 1A the time, can prevent to tangle mutually between the part of cover 10A etc. arrangement part easily on part feeding device.Thereby, can enjoy the action effect identical with the 1st embodiment, simultaneously, be well suited for the mass production that assembles by automat, be closely related with reducing cost.

And, when this endoscope plug body 101 is installed under the state of access portal portion 3, that is, be installed under the state on the joint 3a (with reference to Figure 28) at plug frame 113, can make the bottom of plunger member 114 be configured in the opposed position of joint 3a on.Herein, the bottom of this plunger member 114 is adjacent in the inner periphery portion that is configured in joint 3a.Thereby, when the inner periphery portion of the bottom of plunger member 114 and joint 3a becomes the state that is adjacent to installation respectively, form the shape that can keep watertightness between the two.

Cover 112 and the roughly the same function of cover 10A performance as the endoscope plug body 1A of the variation 1 of above-mentioned the 1st embodiment.Specifically, cover 112 has grip part 112a and extension 112b.Wherein, grip part 112a forms, and it has and is formed on the same substantially function of tang portion 12 on the above-mentioned cover 10A, and when with cover 112 during with respect to 113 mounting or dismounting of plug frame, the mode can grip by finger etc. makes it outstanding facing one direction.On the other hand, extension 112b is equivalent to the connecting portion 13 among the above-mentioned cover 10A, forms towards the direction opposite with grip part 112a to give prominence to, and at its terminal part, is formed with installing hole 112i (with reference to Figure 28).And then, insert the installation jut 113b that is formed on the outer peripheral face of filling in frame 113 to this installing hole 112i.Thereby cover 112 can freely be installed and removed with respect to plug frame 113.

In addition, when middle part at the extension 112b and the grip part 112a of cover 112, when being installed in this cover 112 on the plug frame 113, with this plug frame 113 on facial opposed, with cover 112 molding integratedly by fitting portion 112c, this is formed side-prominent towards plug frame 113 by fitting portion 112c, and is entrenched in above the plug frame of above-mentioned plug frame 113 on the peristome 113a.Had function as cap by fitting portion 112c, it is installed in above the plug frame of plug frame 113 on the peristome 113a dismantledly.This by the outer peripheral face of the close front end of fitting portion 112c on, molding flange part 112d.The external diameter of this flange part 112d forms bigger a little than the internal diameter of peristome 113a above the above-mentioned plug frame.And then, cover 112 by fitting portion 112c by strain, can on the plug frame of plug frame 113, tear open by the enterprising luggage of peristome 113a.

And then, be formed with cover 112 by the position of fitting portion 112c on, be formed with: treatment apparatus introduction part 112e, it is the shape that treatment apparatus 9 (with reference to figure 1) imports easily, for example is roughly hemispheric space by section and constitutes; And narrow slit 112f (also with reference to Figure 27), it is arranged on this treatment apparatus introduction part 112e continuously.

Thereby, even under the state that cover 112 is installed on the plug frame 113, treatment apparatus 9 (with reference to figure 1) also can be inserted in the circulation passage 7 by the slotting treatment apparatus that leads to of the aperture 114b of narrow slit 112f and plunger member 114 from the treatment apparatus introduction part 112e of cover 112.At this moment, narrow slit 112f and aperture 114b can guarantee the inside of the slotting circulation passage 7 of treatment apparatus and the watertightness between the outside by being adjacent to the outer peripheral face of treatment apparatus 9.

On the other hand, under the state that cover 112 is installed on the plug frame 113, and, as shown in figure 27, make narrow slit 112f keep blocked state substantially with respect to the outside treatment apparatus 9 not being inserted under the state that leads in the slotting circulation passage 7 of treatment apparatus by narrow slit 112f and aperture 114b.

And then, as shown in figure 28, under the state that cover 112 is installed on the plug frame 113, be adjacent to the leading section 112g watertightness of flange part 112d the top position of the plunger member 114 that is configured in above-mentioned plug frame 113 inside.

In addition, when in the extension 112b of cover 112 and the middle part between the installing hole 112i, when being installed in this cover 112 on the plug frame 113, fill in the opposed regulation of the sidewall position of frame 113 with this, with the cover 112 convex shaped part 112h that is shaped integratedly, this convex shaped part 112h forms towards the side wall side of plug frame 113 outstanding.This convex shaped part 112h is by near the sidewall butt of the position its leading section with plug frame 113, the extension 112b of inner top cover parts 112.

Plug frame 113 carries out chimeric for endoscope plug body 101 is installed in the access portal portion 3 with the state that covers joint 3a.Specifically, plug frame 113 integral body are made of the general cylindrical shape shape, in the above, connect peristome 113a above the plug frame that is provided with the circular shape.As mentioned above, the flange part 112d by fitting portion 112c of cover 112 is detachable freely is entrenched in this above plug frame on the peristome 113a.

In addition, on the outer peripheral face of plug frame 113, the outstanding integratedly installation jut 113b that constitutes by arrowhead form that is provided with.And then, as mentioned above, being entrenched among this installation jut 113b by installing hole 112i with cover 112, cover 112 can freely be installed and removed with respect to plug frame 113.

In this case, the greatest width dimension of the arrowhead form portion of the close front end of installation jut 113b forms wideer than the width dimensions of installing hole 112i.In addition, the width dimensions of the base end part of installation jut 113b forms with the width dimensions of installing hole 112i basic identical.

Thereby, jut 113b insert logical when being entrenched in the installing hole 112i when will be installed, installing hole 112i is at first by self elasticity, under expanding to than the wideer state of the arrowhead form portion that jut 113b is installed, make after it passes through, in the restoring force of the base end part that jut 113b is installed, return to original size by self.Thereby installing hole 112i and installation jut 113b just become chimerism, therefore jut 113b are installed and are not easy to throw off from installing hole 112i.Thereby, even cover 112 by fitting portion 112c with the plug frame 113 the plug frame above peristome 113a become under the state of having thrown off, also make cover 112 be not easy from the plug frame 113 come off.

And then, be formed with plug frame flange part 113c in the outer edge of the upper face side of filling in frame 113.In addition, on the outer peripheral face of the opposition side at the formation position of above-mentioned installation jut 113b, formed jut 113d, jut 113d from the lower surface of plug frame 113 towards the outside outstanding the setting.

This jut 113d is equivalent to the jut 32 as the endoscope plug body 1 of above-mentioned the 1st embodiment, for endoscope plug body 101 is unloaded from access portal portion 3, its keep on one side along the plug frame 113 along the Zhou Fangxiang continuum of states, destroy the subregion of plug frame 113 on one side, play as the function of destroying a unitary part.Specifically, jut 113d as shown in figure 22, with respect to the plug frame 113 the lower surface have angle θ degree (°) inclination, form towards oblique upper.In this case, as angle θ degree (°), be preferably set to the scope of 10 °＜θ＜70 °.

And then, on the inner peripheral surface of the close lower end of filling in frame 113, as shown in figure 28, be formed with fastener 113e towards interior side-prominent setting.This fastener 113e ends by blocking along the periphery of joint 3a, plays plug frame 113 is installed in the function as an example of card stop element on the joint 3a.Specifically, when fastener 113e will fill in frame 113 and be installed in joint 3a and go up, end in the outer edge of this joint 3a, play a part anti-detent plug frame 113 and self come off by card.Thereby the internal diameter of fastener 113e is set to a little littler than the external diameter of joint 3a.And then the fastener 113e of plug frame 113 can be installed on the joint 3a by strain.

And, on fastener 113e,, on four direction, be formed with from the inner peripheral surface notch 113f of direction outward as Figure 25 and shown in Figure 26.And notch 113f is equivalent to the recess 39 in the endoscope plug body 1 of above-mentioned the 1st embodiment.In addition, on the outer peripheral face of close lower end of plug frame 113, with opposed each position of above-mentioned notch 113f, notch 113g outside being formed with.And outside notch 113g is equivalent to the V word shape groove 33 in the endoscope plug body 1 of above-mentioned the 1st embodiment.By forming such notch 113f and outside notch 113g, on the peripheral part of the close lower end of filling in frame 113, be formed with thinner wall section 113h.This thinner wall section 113h is basic identical with the situation that is formed on the 1st thinner wall section 41 on the above-mentioned endoscope plug body 1, it is member with plug frame 113 thin-walled properties, play with other zone of filling in frame 113 and compare, as the zone of weakening fracture strength by the function of an example of fracture portion.Specifically, thinner wall section 113h is formed into than fastener 113e and more leans on upside, makes its transversal card end the fastener branch of the fastener 113e on joint 3a.And then, 2 positions, both sides that are formed on the base end side of jut 113d among 4 thinner wall section 113h.

Like this, the jut 113d that is formed with thinner wall section 113h at the position, both sides plays the function as an example of operating portion, and it is used for by applying the loading of regulation, makes the fracture operation of thinner wall section 113h fracture.Described jut 113d is by breaking to form the thinner wall section 113h on its position, both sides, for example do not destroy plug frame flange part 113c and keep its shape, can keep on one side along the Zhou Fangxiang continuum of states of plug frame 113, destroy the subregion of the plug frame 113 of a part that the fastener comprise fastener 113e divide on one side.

And, because example by fracture portion shown in the above-mentioned thinner wall section 113h, comprise destruction under the situation of subregion of plug frame 113 of the part that the fastener of fastener 113e divides, the zone of being ruptured, therefore, position, both sides along jut 113d, promptly fill in the edge of the subregion of frame 113 along this, transversal fastener 113e, and be formed near the zone of an end (for example the end of the opening of slotting pass joint 3a) that reaches plug frame 113, compare with other zone of plug frame 113, as long as weaken fracture strength.In the case, described for example both can be the member that makes plug frame 113 thin-walled properties as thinner wall section 113h by fracture portion, also can be that through hole is set in described zone intermittently, to become the member of the sewing machine pinprick shape that weakens fracture strength.

On the other hand, in jut 113d, with the face of the opposed side of outer peripheral face of the drum of plug frame 113 on, as shown in figure 22, be formed with reinforcement 113i.This reinforcement 113i forms the outer peripheral face of the drum that connects jut 113d and plug frame 113.And then this reinforcement 113i forms and has width dimensions H as shown in figure 23.And the upper end (with reference to the symbol E of Figure 22, Figure 28) of the reinforcement 113i of plug frame 113 sides is configured on the position of the upper surface (with reference to the symbol K of Figure 28) that is lower than joint 3a.

And then, when endoscope plug body 101 is installed in the access portal portion 3, that is, in the time of will filling in frame 113 and be installed in joint 3a and go up, utilize the elasticity of plug frame 113, expand the external diameter of joint 3a to by internal diameter with fastener 113e, can install.At this moment, each of each thinner wall section 113h is not stretched by fracture ground equably.

Below, the effect of the endoscope plug body 101 of the present embodiment of such formation this endoscope plug body 101 when access portal portion 3 breaks away from is described.
