The bright clinical application method for taking sundries tool 10 understands see also the associated description in US5465731, to be better understood by this
The purposes of invention.
Fig. 7 depicts a kind of typical specimen bag 100 of the prior art.The specimen bag 100 is usually by monolithic thin film (piece
Material) folding is welded or two panels film (sheet material) overlapping is welded.The material of film (sheet material) includes but is not limited to poly- second
Alkene, polyvinyl chloride, polypropylene, nylon, Teflon, thermo-setting elastomer (such as silica gel) and thermoplastic elastomer (TPE) (such as poly- ammonia
Ester).The technique of film (sheet material) welding includes but is not limited to heat welding, ultrasonic bonding, high-frequency welding, radiation welding, arteries and veins
Punching welding etc..The specimen bag 100 of this example is welded using the overlapping heating of two panels polyethylene film.
Fig. 6 describes a kind of representative heat welding (referred to as heat seal) process of the existing manufacturing technology of specimen bag.Heat-sealing machine 60
It connect and can move along the vertical direction comprising the pedestal 66 and connected to it fuselage 67 fixed with ground installation, and with fuselage 67
Dynamic upper heat seal dynamic model 64 and the lower heat seal cover half 65 being connected and fixed with fuselage 67.The heat seal process of the specimen bag 100 can letter
It is singly expressed as, first adjusts heat seal parameter (mainly include heat-seal temperature, heat sealed time and heat seal pressure), then by 103 He of film
Film 104 is overlapped and is placed on lower heat seal cover half 65, finally starts the heat seal welding that heat-sealing machine completes specimen bag 100.
One those skilled in the art is to be understood that the film heat seal (welding), i.e., in the molten state, film
By the polymer segment phase counterdiffusion of heat seal region surface, infiltration, mutually wind so that biplate (or multi-disc) film welding exists
Together.With reference to Fig. 7, bag face 103 and the mutual welding in bag face 104 form the specimen bag 100 comprising heat seal seam 105.Fig. 8 is depicted
The schematic partial sectional view of 105 any position of heat seal seam, i.e., it is (thin that the described specimen bag 100 finer can be divided into film substrate 131
Film base material 151), transitional region 132 (transitional region 152) and welding area 133 (welding area 153).During film heat seal,
Under the action of heat seal pressure, the film in a molten state in heat seal region is made to be calendered extrusion, to form the transition
Region 132 (transitional region 152).The film thickness of the transitional region 132 (152) is less than the film substrate 131 (151)
Thickness.
In general, according to the heat sealing strength and failure mode difference of welding area and transitional region, it can be by the heat seal seam
It is divided into underheat conjunction, three classifications of standard heat seal and excessive heat seal.The underheat is closed, i.e. the surface in heat seal region is melted, ginseng
With the thinner thickness of the film of heat seal, failure mode when heat sealing strength is tested is welding area removing, and test result is lower than
Target value.The thickness of the standard heat seal, i.e. film that the surface in heat seal region is melted, participating in heat seal is moderate, and fail mould
Formula is welding area removing, and heat sealing strength test result reaches target value.The excessive heat seal, i.e. the surface quilt in heat seal region
The thickness of fusing, participation heat seal film is too many, causes the thickness of the transitional region significantly thinning, so that transitional region
Structural strength be significantly lower than the peel strength of the welding area, this phenomenon is often referred to simply as " root is cut ", and the mould that fails
Formula is transitional region fracture, and heat sealing strength test result is lower than target value.In addition in standard heat seal, claim heat sealing strength test value most
Big heat seal seam is best heat seal seam.One those skilled in the art is appreciated that using different heat seal parameters, determines
The heat seal seam 105 is that underheat is closed, standard heat seal or excessive heat seal.
One those of ordinary skill is readily apparent that, can pass through best heat seal parameter needed for experiment acquirement standard heat seal.Food
In product packaging and medical package field, especially in blood product packaging bag manufacturing field, plastic film heat seal has been carried out greatly
Quantity research.It is disclosed the prior art indicate that, usual heat-seal temperature, the comprehensive function of heat seal pressure and heat sealed time determines modeling
Expect the heat sealing quality of film, and influence of the heat-seal temperature for heat sealing quality is maximum, heat seal pressure and heat sealed time are to described
The influence of heat sealing quality is relatively small or negligible.
In food packaging and medical package field, best heat-seal temperature is usually obtained with experimental method.Usually preset
One heat sealing strength receives standard (i.e. target value), then according to heat seal of the test method to test specimen as defined in authoritative standard
Intensity is tested, and test result satisfaction receives standard and then assert that the heat-seal temperature is reasonable temperature or optimum temperature.Such as it is right
In peelable packaging bag (packaging bag manually torn when convenient to use), usually according to the " ASTM of American Society Testing and Materials
F88 flexible barrier material sealing intensity test method " it is tested, dominant failure mode when sample test is the stripping of heat seal region
From (Fig. 9), test result is essentially identical to the true heat sealing strength of sample.And for bags of blood, bag filter etc. can not
It removes packaging bag (packaging bag when use without manually tearing), usually according to the " ASTM of American Society Testing and Materials
F2029 measures flexible material heat seal capability thermal weld code of practice by measurement sealing intensity " it is tested, sample test
When dominant failure mode be that heat seal region removes (Fig. 9) or transitional region and is broken (Figure 10).The transitional region phenomenon of rupture,
Being primarily due to local excessive heat seal causes the thickness of corresponding transitional region significantly thinning, and the intensity so as to cause part significantly drops
It is low.When failure mode when sample test is that transitional region is broken, the true heat seal that test result is less than sample is strong
Degree.But as long as test result, which meets, receives standard, still assert that the heat-seal temperature is reasonable temperature or optimum temperature.It should
It particularly points out, the establishment of the optimum temperature depends primarily on its test method and receives standard, therefore best heat-seal temperature
Do not indicate that the heat sealing strength of its heat seal seam is best.When heat sealing strength test failure mode be heat seal region remove rather than
When transitional region is broken, and when the peeling force maximum of heat seal region, referred to as best heat seal, and the heat-seal temperature of its sample is referred to as best
Heat-seal temperature, more accurately, commonly referred to as this optimum temperature parameter is theoretical optimum temperature or ideal optimum temperature.
When usually obtaining best heat-seal temperature with experimental method, not by clamping apparatus error, by heat-sealing film error and environment
The factors such as error introduce overall merit.And when actual production manufacture, due to film thickness error, film out-of-flatness, heat seal work folder
Have an error, the combined influence of the factors such as uneven heating, especially for heat seal seam is longer and the poor material of sealability (such as
Thermoplastic elastomer (TPE)), it heat seal (welding) is carried out using theoretical optimum temperature is easy to appear Local residues gap, is i.e. heat seal seam
Sealing integrity is not up to standard.Product longer for heat seal seam or that heat sealing performance is poor, the sealing integrity of heat seal seam and
Heat sealing strength be it is conflicting, for ensure sealing integrity generally have to using excessively heat-sealing, i.e., must sacrifice heat sealing strength.
It is the most critical index that must satisfy in the sealing integrity of food packaging and medical package field, packaging, and heat sealing strength
For secondary index.Food packaging and medical package field are usually to meet sealing integrity as most critical index, in this premise item
Lower heat-seal temperature is selected under part to obtain preferable heat sealing strength, the best heat-seal temperature used is most usually above theory
Good temperature.When carrying out heat seal with this best heat-seal temperature, most of region of usual same heat seal seam belongs to the standard hot
Close and its regional area belongs to the excessive heat seal.
Up to the present, disclosed, less, mesh is studied for the heat seal of laparoscope dedicated specimen bag of the present invention
The experience of food packaging and medical package field is usually continued to use in the preceding specimen bag batch heat seal when manufacturing, i.e., theoretical using being higher than
Optimum temperature carry out heat seal with simultaneously obtain sealing integrity and preferable heat sealing strength, inevitably, the formation it is same
Most of region of one heat seal seam belongs to the standard heat seal and its regional area belongs to the excessive heat seal.With reference to Fig. 7, figure
8 and Figure 11, such as the specimen bag 100 is under the conditions of best heat-seal temperature when heat seal, most of area of the heat seal seam 105
Domain belongs to standard heat seal (its heat seal seam figure is referring to Fig. 8), and the regional area of heat seal seam 105 belongs to excessive heat seal (its heat
Splice grafting stitches figure referring to Figure 11).With reference to Figure 11, as it was noted above, the local excessive heat seal leads to 132 part of transitional region
It is significant thinning, it is significantly reduced so as to cause the intensity of part.
With reference to Fig. 4-5, as it was noted above, by the pathological tissues or organ of specimen bag and its splendid attire via puncture cannula or warp
When being taken out by skin incision, since puncture cannula internal diameter or Minimally Invasive Surgery notch are smaller, specimen bag is held by very big extruding force
Easily lead to extraction bag rupture.And intensity caused by local excessive heat seal significantly reduces the rupture wind for just greatly increasing specimen bag
Danger.One those skilled in the art is readily apparent that the intensity of specimen bag can be increased by increasing film thickness, however when specimen bag is used for
Aforementioned when taking in sundries tool, since the size of conduit limits, conduit can not be accommodated in by increasing film thickness and typically resulting in specimen bag
Interior or specimen bag can not be released from conduit.Simultaneously as specimen bag has sealed commonly used in containing pathological tissues or organ
Whole property is also of equal importance, any work revealed the risk that can all can increase patient's inadvertent contamination or increase subsequent cleaning treatment
It measures.The hot bonding method for obtaining sealing integrity and the hot bonding method for obtaining best heat sealing strength be it is conflicting, to current
Until there are no good methods to solve this conflict.
In view of the size-constrained system of film thickness, and very big extruding force is subjected to when specimen bag clinical application, therefore right
It is that the upper limit, intensity are not the bigger the better in the pursuit of specimen bag intensity.And it is broken in up to the present specimen bag clinical application
The case split still happens occasionally.Those skilled in the art may be it will be appreciated that most have generation what this field maintained the leading position
The product of table, i.e., with trade nameEndo CatchTMWithMass production is sold and what is used takes sundries
Tool, there is also a degree of cracking probability.Up to the present, specimen bag rupture almost not can avoid in use, and
The transitional region in commissure usually occurs for rupture；Disclosed control measure generally include to select better thin-film material
With better welding control Heat-seal parameter, these measures can a degree of reduction weld seam slip gradient, however still need to continue to change
Into.
The structure and composition of first embodiment of the present invention specimen bag 200 is illustrated in detail in Figure 12-14.As it was noted above,
Obtain the hot bonding method of sealing integrity and best heat sealing strength be it is conflicting, that is, be difficult to by best heat seal parametric method come
The heat sealing quality for controlling the specimen bag 200 also ensures that its weld seam while both having had sealing integrity at its weld seam whole
In standard hot conjunction state, to obtain best heat sealing strength.In one aspect of the invention, aforementioned punching is solved using more weld seam methods
It is prominent.Finer, the specimen bag 200 includes at least 2 weld seams, wherein outermost side weld realization sealing integrity, and inside
Weld seam mainly realize good heat sealing strength.
With reference to Figure 12, the specimen bag 200 includes sack 201 that is openable and collapsing, and is extended from the sack 201
Made of bag body 202.The sack 201 includes around the tunnel of sack 211, to accommodate spreading mechanism 20 and binding 50.Institute
Stating bag body 202 includes the first film 203 and the second film 205, in a kind of embodiment, two chip sizes and shape are roughly the same
The first film 203 and the second film 205 it is overlapped, then to the entire outer edge of lap carry out heating welding (letter
Heat seal) the first heat seal seam 204 (being hereinafter referred to as the first weld seam 204) is formed, thus by the first film 203 and the second film
205 thermal synthesis one have the bag-shaped entirety of opening.The heat seal seam shape that first weld seam 204 is formed along the edge of bag body
It is approximate U-shaped.The bag body 202 also includes the second heat seal seam 208 (being hereinafter the second weld seam 208), second weldering
The inside of the first weld seam 204 is arranged in seam 208.Second weld seam 208 described in this example and first weld seam 204 are substantially flat
Row, and vacant section 206 is provided between first weld seam 204 and the second weld seam 208.However first weld seam 204 and
Two weld seams 208 can also be not parallel.Although by the way of heating welding that the first film 203 and second is thin in this example
Film 205 welds together, however can also use ultrasonic bonding, high-frequency welding, radiation welding, the modes such as pulse welding.Institute
The material for stating film 203 and film 205 includes but is not limited to polyethylene, polyvinyl chloride, polypropylene, nylon, Teflon, thermosetting property
Elastomer (such as silica gel) and thermoplastic elastomer (TPE) (such as polyurethane).In this example, the first film 203 and the second film
205 are all made of polyurethane.
In order to better understand this programme, looks back use heating welding (heat seal) legal system described previously first herein and make sample
Underheat when bag is closed, standard heat seal and excessive heat seal situation, and obtains maximum heat sealing strength using test method(s), and best heat seal connects
The method of seam and theoretical optimum temperature.One those skilled in the art is it is contemplated that different materials or the different thickness of similar material
Degree or same type of material same thickness but different hardness, the maximum heat sealing strength obtained using experimental method, best heat seal seam and
The difference of theoretical optimum temperature is very big, therefore a certain concrete case in the present invention not for a certain specific material is ground
Study carefully.
When using other welding manners, the main distinction is that the source of welding energy is different, and the essence of welding is identical.It adopts
Manufacture specimen bag with other welding manners, the film being welded to each other be also in the molten state, film by heat seal region
The counterdiffusion of polymer segment phase, the infiltration on surface, mutually wind, so that biplate (or multi-disc) film is welded together.Specimen bag
It finer can also be divided into film substrate, transitional region and welding area.During film heat seal, in the effect of heat seal pressure
Under, so that the film in a molten state in heat seal region is calendered extrusion, to form the transitional region.The transitional region
Film thickness be less than the film substrate thickness.Its solder joint can also approximately be divided into deficient welding and (be equal to underheat
Close), standard welding (being equal to standard fusion) and excessive welding (being equal to excessive heat seal).One those skilled in the art can be with
Understand, under different welding manners, the parameter for influencing welding quality is different, using different welding parameters, determines welding
Seam belongs to deficient welding, standard welding or excessive welding.Equally, other well known welding manners, can also pass through experimental method
The maximum weld strength of acquisition, best solder joint and theoretical best welding parameter.
Although those skilled in the art is to be understood that specimen bag in different materials, different structures, or difference
Welding manner etc. under the conditions of, the factor for influencing its solder joint quality is widely different, but can be used identical test method and
Receive standard to control its seam quality, while also associated control parameters can be obtained using experimental method.Clearly to illustrate this hair
Bright thought such as gives a definition to the relevant term of specimen bag solder joint quality at this:
Owe welding: i.e. the thinner thickness of film that the surface of welding region is melted, participating in fusion, weld strength test
When failure mode be specimen bag welding area remove, and test result be lower than target value.
Standard welding: i.e. the thickness of film that the surface of welding region is melted, participating in fusion is moderate, and weld strength is surveyed
Failure mode when examination is that the welding area of specimen bag is removed, and test result reaches target value.
Excessive welding: i.e. the thickness of film that the surface of welding region is melted, participating in fusion is too many, leads to specimen bag
The thickness of transitional region between welding area and specimen bag substrate is significantly thinning, and failure mode when weld strength is tested is
Transitional region fracture, heat sealing strength test result are lower than target value.
Owe fusion weld: weld strength test shows as owing the weld seam of welding.
Standard fusion weld: weld strength tests the weld seam for showing as standard welding.
Excessive fusion weld: weld strength tests the weld seam for showing as excessive welding.
Best weld seam: failure mode when weld strength is tested is that the welding area of specimen bag is removed, and test result reaches
To the weld seam of maximum value.Theoretical best welding parameter: welding parameter when best weld seam is obtained.
As it will be easily appreciated by one skilled in the art that carrying out film solder strength test according to ASTM F2029 or ASTM F88
When, it needs that sample is prepared into the band-like test specimen that width is 25mm, 20mm or 15mm in advance.It is tested with long weld seam
After sample is prepared to multiple band-like test specimens, test result may include to owe welding, standard welding and excessive welding,
It is mixing weld seam that this, which defines such long weld seam,.
Owe welding and standard welding mixing weld seam: simultaneously comprising owing weld and standard weld in same weld seam.
Standard welding and excessive welding mixing weld seam: including standard weld and excessive weld portion in same weld seam simultaneously
Point.
Based on aforementioned theoretical and finer this example of anatomy of related definition, to facilitate introduction those skilled in the art more preferable
The core technology for understanding this programme.Figure 13 depicts the schematic partial sectional view of the position 13-13 of bag body 202.The first film 203 from
Outer edge inwardly can approximation be divided into the first welding area 231, First Transition area 233, the second welding area 235, the second transition region 237
With specimen bag substrate 239.Similarly, the second film 205 from outer edge inwardly can approximation be divided into the first welding area 251, the first mistake
Cross area 253, the second welding area 255, the second transition region 257 and specimen bag substrate 259.Figure 14 depicts the second weldering of bag body 202
The schematic partial sectional view of the position 14-14 of seam 208.There may be one or more slits for the regional area of second weld seam 208
Gap.Weld seam 208 described in this example contains micro chink 262 and micro chink 266 in 14-14 weld seam section.Those skilled in the art
For member it is appreciated that when the first film 203 is identical with thickness with the material of the second film 205, optional one of piece is thin
Film research.When the material or not identical thickness of the first film 203 and the second film 205, select wherein most weak
One sheet of film research.It is main study subject that the first film 203 is selected in this example.
In a kind of embodiment, first weld seam 204 belongs to excessive fusion weld, or belongs to standard welding and excessively
Welding mixing weld seam；And the second weld seam 208 belongs to deficient welding and standard welding mixing weld seam.In a kind of manufacturing method, the mark
This bag 200 is manufactured in the method for heating welding (heat seal).The first film 203 and the second film are obtained using experimental method first
The theoretical optimum temperature of 205 heat seals welding.In the heat seal manufacturing process of first weld seam 204, it is ensured that the heat-seal mould of quantity of heat given up
The temperature of any position be more than or equal to the theoretical optimum temperature, it is ensured that without owing on whole weld seam of first weld seam 204
Welding ensures its sealing integrity.All excessive welding or standard welding and local excessive are molten for i.e. described first weld seam 204
It connects and combines.With reference to Figure 13, as it was noted above, the excessive welding mode causes aforementioned First Transition in a kind of implementation
The thickness in region 233 reduces by 15%~30%；When the thickness in First Transition region 233 under extreme case reduces by 30%, weldering
Typical " root is cut " phenomenon is shown when stitching strength test, but since first weld seam 204 mainly realizes sealing integrity,
Still can receive.In a kind of preferred implementation, the first weld seam 204 is set to show as standard welding by reducing heat-seal temperature
With the mixing weld seam of excessive welding, i.e., lower heat seal temperature is used under the premise of ensuring the sealing integrity of the first weld seam 204
Degree reduces degree with the thickness for reducing First Transition region 233, enhances the weld strength of the first weld seam 204.And the second weld seam 208
Heat seal manufacturing process in, it is ensured that the temperature of any position of the heat-seal mould of quantity of heat given up is less than or equal to the theoretical best temperature
Degree, and ensure without excessive welding on whole weld seam of second weld seam 208, to increase the weld strength of the second weld seam 208.Such as
It is described previously, due to the influence of various error components, especially for long weld seam, it is difficult to ensure whole weld seam is all in standard welding
State (or cost of implementation is very high), therefore second weld seam 208 allows comprising owing welding and standard welding.With reference to Figure 13,
As it was noted above, when being manufactured in a manner of standard welding, the thickness of second transitional region 237 is reduced in a kind of implementation
Control is 0~15%.Its weld strength test when failure mode be specimen bag welding area 208 removing rather than described second
Transitional region 237 is broken.In a kind of preferred scheme, on the whole weld seam for ensuring the second weld seam 208 without excessive welding before
Put the weld strength for enhancing the second weld seam 208 using higher heat-seal temperature.Since second weld seam 208 does not allow to wrap
Containing excessive fusion weld, due to the influence of various error components, especially for long weld seam, then in whole second weld seam 208 inevitably
Occur owing fusion weld.With reference to shown in Figure 14, the weld seam 208 contains micro chink 262 and micro chink in 14-14 weld seam section
266.Since second weld seam 208 is not necessary to guaranty that sealing integrity, local micro chink (deficient welding) is can to receive
's.
The principle of the specimen bag 200, application method and advantage: as it was noted above, food packaging and medical package field,
Such as blood packaging bag, the uniform pressure (pressure) transmitted using the weld seam of its packaging bag when fracture failure by liquid, because
This is for blood packaging bag or similar products, using multiple weld seam method almost without meaning.However the clinical application of specimen bag and
Failure mode and said blood packaging are completely different.The sealing integrity of specimen bag weld seam is to the lesion that ensures to cut down
Tissue or the watery blood in organ or body fluid will not be permeated and is leaked in patient's body lumen.With reference to Fig. 4-5 as it can be seen that being loaded with lesion group
When the specimen bag knitted is stored and extracted, usual sack is not completely sealed；Thus a those skilled in the art can manage
Solution, when the specimen bag store and is extracted, the extruding force very little that the liquid of internal splendid attire is not under compression power or is subject to, otherwise liquid
Body is spouting by the sack not being fully sealed from specimen bag.Therefore the liquid contained in specimen bag passes through the second weld seam 208
Pressure (pressure) very little of the first weld seam 204 is passed to afterwards.In addition, those skilled in the art, which is to be understood that, works as sample
When bag is stored and extracted, contains tissue and non-uniform extruding force is applied for sample bag body, and then be transformed into specimen bag bag body
Internal force be transferred to the second weld seam 208.Since the pathological tissues are not fluids, the slit on the second weld seam 208 cannot pass through
Power is simultaneously transferred to the first weld seam 204 by gap.Those skilled in the art is to be understood that the deficient welding in part can't be significant
Reduce weld strength.Plastic film is typical notch sensitiveness material, and Undercutting Phenomenon caused by local excessive welding is easy to lead
Cause weld seam is tearing and fast growth by larger internal force, to significantly reduce the intensity of specimen bag.Meanwhile even if part is owed
Heat seal large effect weld strength, the bond open at local subcooling's conjunction of the second weld seam, but film does not rupture, and
And it there remains the first weld seam as lower one of defence line.Therefore, the broken probability of specimen bag still can significantly be reduced.To sum up institute
It states, the outermost side weld realizes sealing integrity, and the weld seam of inside mainly realizes that the scheme of heat sealing strength meets well
Specimen bag clinical application demand, preferably resolves the conflict of sealing integrity and best heat seal strength.
