Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1, the cavity mirror object-obtaining device of a kind of controlled bag mouth size and opening and closing, comprises loop bar 1, action bars 2, elastic ring 3 and specimen bag 4.Institute's specimen bag 4 is pliable and tough bag, and it is outside that unique bag mouth 41 is movably set in elastic ring 3.Energy compression after elastic ring 3 is stressed, can restore when not stressing, elastic ring 3 tail end is fixedly connected on action bars 2 head end.Action bars 2 activity is nested with overlaps intracavity at loop bar 1, and elastic ring 3 can slip into the mantle cavity distortion of described loop bar 1 with described action bars 2 and tighten up the collar extension of elastic ring 3, thus closes described specimen bag 4 bag mouth 41.
Be more than basic module and the structure of current all cavity mirror object-obtaining devices: loop bar 1 head end inner chamber is for holding the specimen bag 4 and elastic ring 3 that do not open, and elastic ring 3 activity is nested with in specimen bag 4 bag mouth 41.When outside the chamber that elastic ring 3 is released loop bar 1, under the recovery tension force effect of elastic ring 3, the collar extension of elastic ring 3 is open, and bag mouth 41 opening subsequently of specimen bag 4, is convenient to the specimen of excision to put into.The head end of action bars 2 is fixedly connected with the tail end of elastic ring 3, is convenient to operate elastic ring 3.
The cavity mirror object-obtaining device of controlled bag mouth size and opening and closing also comprises the bag mouth controlling organization 5 that bag mouth 41 for controlling described specimen bag 4 is open and close, when bag mouth controlling organization 5 makes elastic ring 3 body deformability be retracted into loop bar 1 intracavity, the bag mouth 41 of specimen bag 4 closes, and makes the bag mouth 41 of specimen bag 4 open when collar extension effusion loop bar 1 endoluminal expansion of described elastic ring 3 restores simultaneously.
The setting of bag mouth controlling organization 5 makes the bag mouth 41 of specimen bag 4 open and closes all controlled, and the resting state of specimen bag 4 can reset in time.When same operation needs to excise multiple specimen, often excise a specimen and specimen can be loaded taking-up body cavity in specimen bag 4.Then specimen bag 4 is resetted again and enter resting state, again reuse during Operated Specimens.Waiting for without the need to being placed in body cavity after excising single specimen, taking out together after waiting multiple specimen all to excise, avoiding specimen and be placed in body cavity and may pollute or plant.Also multiple cavity mirror object-obtaining device need not be wasted in the multiple specimen of excision.When specimen bag 4 bag mouth 41 mistake is closed, only need again to open specimen bag 4 bag mouth 41 by controlling organization 5, without the need to extracting loop bar 1, the cavity mirror object-obtaining device more without the need to more renewing.
As shown in Figure 2, action bars 2 tail end arranges interior bar limit body 21, action bars 2 is when loop bar 1 intracavity forward slip exposes outside the chamber of loop bar 1 to the collar extension of elastic ring 3, and interior bar limit body 21 holds at loop bar 1 tail end, makes action bars 2 cannot continue forward slip at loop bar 1 intracavity.
The tail end of action bars 2 is arranged interior bar limit body 21, when elastic ring 3 collar extension of action bars 2 head end goes out the outlet of loop bar 1, action bars and limited.Loop bar 1 pair of action bars carries out spacing, and when avoiding practical operation, action bars 2 was strayed into deeply, may shine into injury to operation spaces intra organizations, while can increase the degree of accuracy operated.
As shown in Figure 3, elastic ring 3 cross section is class rectangle, and elastic ring square-section major axis 3E is vertical with elastic ring 3 collar extension plane 3F.Like this, when elastic ring 3 loads excision specimen after specimen bag 4 bag mouth 41 is opened, entrance (the i.e. collar extension plane 3F) direction of bag mouth 41 is elastic ring 3 class square-section major axis 3E supports bag mouth 41, can provide larger support force, when avoiding loading excision specimen, elastic ring 3 collar extension excessive deformation causes specimen to load difficulty.
Simultaneously, after the bag mouth 41 of excision specimen loading specimen bag 4 is closed, tractive action bars 2 and elastic ring 3, and then during tractive taking-up specimen bag 4, the bag mouth 41 of specimen bag 4 closed slides the ring body head end 3A gathered at elastic ring 3, specimen bag 4 takes out the horizontal plane that lifting surface area is the major cross-sectional axis of ring body head end 3A, i.e. the macropinacoid of elastic ring 3 class square-section.Specimen bag 4 tractive lifting surface area significantly increases, and stressed pressure reduces, and is not easy because the cutting of elastic ring 3 pairs of specimen bags 4 causes specimen bag 4 to rupture, more safe and reliable during taking-up excision specimen.
The bag mouth head end 4A of specimen bag 4 bag mouth 41 is fixedly connected with elastic ring 3 ring body head end 3A.Its meaning is: avoid action bars 2 in loop bar 1 during forward, and elastic ring 2 ring body head end 3A overflows from the crack of specimen bag 4 bag mouth head end 4A.And then causing elastic ring 3 to release after loop bar 1 expansion is restored to annular, the bag mouth 41 of specimen bag 4 is but gathered and cannot be opened the annular of elastic ring 3 is latter half of, and when reducing concrete operations, fault may.
Specimen bag 4 surface is coated with hydrophilic coating.The feature of hydrophilic coating is very lubricated in a wetted condition, and frictional force is minimum.Its meaning is that reducing specimen bag 4 takes out difficulty, and hydrophilic coating material has multiple, comprises polyvinyl pyrrolidone etc., states no longer one by one herein.
As shown in Figures 4 and 5, bag mouth controlling organization 5 comprise activity be nested with elastic ring 3 tail end or action bars 2 head end gliding mass 51 and be arranged on the force ring 52 of loop bar 1 head end.The gliding mass head end 5B of gliding mass 51 is fixedly connected with the bag mouth tail end 4B of specimen bag 4, and gliding mass 51 can be connected with force ring 52 temporarily and get loose.
Gliding mass 51 can slide outside the head end of the action bars 2 of loop bar 1 intracavity and outside elastic ring 3 tail end, and when retiring tractive action bars 2 to loop bar 1 intracavity, the ring body after elastic ring 3 is out of shape also can be nested with chamber tract and slide along the inside of gliding mass 51.
Before use, the gliding mass 51 be fixedly connected with specimen bag 4 bag mouth tail end 4B is positioned at elastic ring 3 tail end to the cavity mirror object-obtaining device of controlled bag mouth size and opening and closing, is positioned at action bars 2 head end simultaneously.Now, elastic ring 3 is compressed to two linear elasticity bars, and specimen bag 4 bag mouth 41 becomes two linearly with elastic ring 3 synchronous folding, and described elastic ring 3 and specimen bag 4 are all compressed in the front end inner chamber of loop bar 1.The tail end of elastic ring 3 is fixedly connected with action bars, and activity is nested with the intracavity in the loop bar chamber 12 at loop bar 1.
During use:
First to loop bar 1 head end outlet forward operation bar 2, specimen bag 4, elastic ring 3 and gliding mass 51 are all passed to loop bar 1 head end exit movement, part collar extension under the multiple Zhang Zuoyong of natural resiliency that elastic ring 3 exposes loop bar is opened, and drives the bag mouth 41 of specimen bag 4 to open.When elastic ring 3 is all exited the loop bar chamber 12 of loop bar 1, whole elastic ring 3 is all opened, and whole specimen bag 4 is also all pushed out loop bar chamber 12, and bag mouth 41 is fully opened.Now, the interior bar limit body 21 of action bars 2 is limited in the tail end import department of loop bar 1, and action bars 2 cannot continue forward.Slide block 51 is now just in time positioned at the force ring 52 of loop bar 1 head end, and action bars 2 can not continue forward, ensure that slide block 51 can not be deviate from outside loop bar 1 loop bar chamber 12.
Then, in specimen bag 4, load specimen by bag mouth 41, specimen retires action bars 2 to loop bar 1 tail end after loading, and now, slide block 51 interacts with force ring 52 and is connected temporarily, and slide block 51 can not be retired backward.Elastic ring 3 compression under the drive of action bars 2 becomes line style, and the internal passage along slide block 51 enters in the loop bar chamber 12 of loop bar 1, and elastic ring 3 collar extension reduces.Simultaneously, specimen bag 4 bag mouth tail end 4B is conflicted by the gliding mass head end 5B of slide block 51, bag mouth 41 temporarily can not enter in the loop bar chamber 12 of loop bar 1, the bag mouth 41 of specimen bag 4 and the collar extension of elastic ring 3 synchronously reduce, finally make the bag mouth 41 of specimen bag 4 gather to the ring body head end 3A of elastic ring 3, thus specimen bag 4 bag mouth 41 is closed.
Continue to the tail end tractive action bars 2 of loop bar 1, the bag mouth 41 that specimen bag 4 gathers closedown is pulled and enters in the loop bar chamber 12 of loop bar 1.Meanwhile, the traction action power of action bars 2 increases to the interim coupling force being greater than slide block 51 and force ring 52, and slide block 51 and force ring 52 interim is connected destroyed, and gliding mass 51 gets loose with the ring 52 that exerts a force.Continue the tail end tractive action bars 2 to loop bar 1, slide block 51 is closed bag mouth 41 Partial synchronization with action bars 2 and specimen bag 4 and is retired in the loop bar chamber 12 of loop bar 1, and the bag mouth 41 of specimen bag 4 is thoroughly closed, and specimen bag 4 content is isolated from the outside.Synchronously retire action bars 2 together with loop bar 1 and specimen bag 4 is pulled out endoscope-assistant surgery otch.
If only have an Operated Specimens, now, specimen taking-up work completes.
If there is multiple excision specimen, fixed by loop bar 1, to loop bar 1 head end push operation bar 2, under action bars 2 tractional force, elastic ring 3, specimen bag 4 and slide block 51 are conflicted stressed to loop bar 1 head end outlet operation by action bars 2.When the bag head end 4A of elastic ring 3 ring body head end 3A and specimen bag 4 be passed the head end exposing loop bar 1 export time, slide block 51 is pushed to again the position of force ring 52, and gliding mass 51 is connected with the ring 52 that exerts a force temporarily.Gliding mass 51 is under the coupling force of force ring 52, and the bag mouth tail end 4B of tractive specimen bag 4, avoids the head end outlet in bag mouth tail end 4B effusion loop bar chamber 12.Continue to pass action bars 2 to loop bar 1 head end, elastic ring more than 3 exposes loop bar 1 and exports, because bag mouth head end 4A is fixedly connected with ring body head end 3A, and bag mouth tail end 4B is by the temporary fixed loop bar chamber 12 of can not overflowing of slide block 51, specimen bag 4 bag mouth 41 is opened under self recovery tension force effect of elastic ring 3.Take out specimen, discharge the gas in specimen bag 4, again specimen bag 4 is drawn in the loop bar chamber 12 of loop bar 1 together with slide block 51, the cavity mirror object-obtaining device of described controlled bag mouth size and opening and closing is again inserted by endoscope-assistant surgery otch, the operation that above-mentioned specimen bag 4 bag mouth 41 is opened can be repeated, take out next specimen.
Action bars 2 tail end arranges tail end easily-folding line 2C, and loop bar 1 can be remained tail end from action bars 2 from the 2C dialysis of tail end easily-folding line and after shirking action bars handle 22 and extract out by action bars 2, and is exposed by action bars 2 head end.Action bars 2 head end arranges action bars 2 described in head end easily-folding line 2D and can be formed after head end easily-folding line 2D dialysis and get thing handle 23, is convenient to excision thing to take out from specimen bag.
The meaning of this vibrational power flow is: when specimen is excessive, only specimen bag 4 bag mouth 41 part synchronously can be drawn out endoscope-assistant surgery otch with loop bar 1, and the bottom that specimen bag 4 loads specimen cannot be drawn out endoscope-assistant surgery otch.Now, the specimen in specimen bag 4 need be carried out pulverization process and can be taken out.
Exposing tail end easily-folding line 2C by passing to be nested with at the action bars 2 of loop bar 1 intracavity, walking crosswise force and making action bars 2 in the fracture of tail end easily-folding line 2C place, taking out the action bars handle 22 that action bars 2 expands.Now can detach loop bar 1 through stump, and then expose head end easily-folding line 2D.Walking crosswise force makes action bars 2 in the fracture of head end easily-folding line 2D place, retains the action bars 2 of suitable length as getting thing handle 23 during follow-up pulverizing specimen.Both be convenient to hand-heldly be beneficial to follow-up crushing operation, avoided again that the remaining Handheld Division of action bars 2 is long causes operation inconvenience.Certainly, the operation destroying action bars 2 can only only have one at Operated Specimens, or implements during last taking-up of multiple specimen, otherwise, by destroying the service behaviour of the cavity mirror object-obtaining device of described controlled bag mouth size and opening and closing, cannot reuse.
It should be noted that, when the specimen needing excision to take out is multiple specimen and cannot pulls out specimen bag 4 through endoscope-assistant surgery otch more greatly, action bars 2 can not be destroyed, the operation of opening specimen bag 4 bag mouth 41 need be carried out on the basis of cavity mirror object-obtaining device integrity retaining described controlled bag mouth size and opening and closing, pulverize and take out specimen, to reuse (operation of opening specimen bag 4 bag mouth 41 is handed over above, no longer repeats).During use, as far as possible first should excise small sample, then excise large specimen, destroy action bars 2 reservation when taking out to facilitate large specimen and get thing handle 23.
The metal material that gliding mass 51 comprises magnetic material with force ring 52 or can be attracted by magnetic material, gliding mass 51 attracts each other with force ring 52.
So, can attract each other when gliding mass 51 closes on force ring 52 and be connected and fixed temporarily, during stressed increasing, can get loose in time.But gliding mass 51 and force ring 52 captivation size are because of being greater than the pulling force of needs when specimen bag 4 bag mouth 41 is opened on elastic ring 3, in order to avoid pulled out the loop bar chamber 12 of loop bar 1 by the frictional force of bag mouth 41 and elastic ring 3, cause operational failure.
As shown in Figure 6, gliding mass 51 arranges resistance area respectively with the relative contact surface of force ring 52, and resistance area comprises adaptive projection 53 or groove 54, the pliable and tough deformable of projection 53, and before and after projection 53, side arranges deformed bumps holding tank 55 and holds the projection after because of stress deformation 53.Resistance area also comprises corresponding concavo-convex alternate frictional force and increases face.Traction force to bag mouth 41 when the setting of resistance area is to make force ring 52 pairs of gliding masses 51 provide specimen bag 4 to open by larger change in friction force, the gliding mass 51 implementing to attract each other to magnetic material is similar to force ring 52 effect, exceeds description.Before and after described projection 53, side arranges deformed bumps holding tank 55 and holds the projection after because of stress deformation 53, and object reduces normal non-slide block 51 position and resistance during force ring 52 relative motion, and reducing too requires great effort when using brings inconvenience.
In a word, controlledly can repeatedly open or close specimen bag 4 bag mouth 41 behind implantation surgery space of the present invention, fine adjustment can be carried out to the size of specimen bag 4 bag mouth 41, the hands art of multiple specimen excision can be used for; The wireless body of loop bar 1 and action bars 2 gap is buried underground and is not easily broken down; That easily shirks when taking out specimen that loop bar 1 retains specimen bag 2 gets thing handle 23, easy to operate; Specimen bag 4 surface is coated with hydrophilic coating, and little being convenient to of frictional force is taken out; During tractive taking-up specimen bag 4, the elastic ring 3 cross section lifting surface area of rectangle is comparatively large, and specimen bag is easy fracture not; When large specimen is not easily taken out, without the need to destroying the integrity of specimen bag 4, the bag mouth 41 of specimen bag 4 can be easy to open, pulverize and take out specimen; Simple and compact for structure, simple and convenient assembly, cost is lower, easy to use, safe and reliable.
