The clinical application method for taking sundries tool 10 of invention, the associated description also referred in US5465731 understands, to be better understood by
Purposes of the invention.
Fig. 7 depicts a kind of typical specimen bag 100 of prior art.The specimen bag 100 is generally by monolithic thin film (piece
Material) doubling is overlapped and is welded, or two panels film (sheet material) is overlapped and is welded.The material of film includes but is not limited to poly- second
Alkene, polyvinyl chloride, polypropylene, nylon, Teflon, thermo-setting elastomer and thermoplastic elastomer (TPE) (such as polyurethane).Film is welded
The technique for connecing includes but is not limited to heating welding, ultrasonic bonding, high-frequency welding, radiation welding, pulse welding etc..It is a kind of existing
In implementation, the specimen bag 100 is heated after being overlapped by the doubling of monolithic polyurethane 101 and is welded.The film 101
Wherein one end crimp and weld to form tunnel 111.The film 101 is several along the direction for being approximately perpendicular to the tunnel 111
What axis of symmetry 102 is folded to form the bag face 103 and bag face 104 for overlapping substantially.Along the bag face 103 and bag face 104
The outward flange shape of overlap carries out heating welding (abbreviation heat seal) and forms heat seal weld seam 105.The bag face 103, bag face 103 and weld seam
105 bags 120 for limiting sack 110 and the closing extended from the sack 110.The tunnel 111 is along described
Sack 110 is approximate circumferentially distributed.
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
Comprising the pedestal 66 and connected fuselage 67 fixed with ground installation, and it is connected and can vertically moves with fuselage 67
Dynamic upper heat seal dynamic model 64 and the lower heat seal cover half 65 being connected with fuselage 67.The heat seal process of the specimen bag 100 can letter
Singly it is expressed as, first adjusts heat seal parameter (mainly including heat-seal temperature, heat sealed time and heat seal pressure), then by the weight of film 101
Fold and be placed on lower heat seal cover half 65, finally start 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
The polymer segment phase counterdiffusion by heat seal region surface, infiltration, mutually winding so that biplate (or multi-disc) film welding exists
Together.With reference to Fig. 7, the mutual welding in bag face 103 and bag face 104 forms the specimen bag 100 comprising heat seal seam 105.Fig. 8 is depicted
The schematic partial sectional view of the optional position of heat seal seam 105, i.e., it is (thin that 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,
In the presence of heat seal pressure, the film in molten condition in heat seal region is set to be calendered extrusion, so as 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.
Generally, it is different with failure mode with the heat sealing strength of transitional region according to welding area, 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 peeled off for welding area, and test result is less than
Desired value.The standard heat seal, the i.e. thickness of film that the surface in heat seal region is melted, participating in heat seal is moderate, and fail mould
Formula is peeled off for welding area, and heat sealing strength test result reaches desired value.The surface quilt of the excessive heat seal, i.e. 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 broken for transitional region, and heat sealing strength test result is less than desired value.In other standard heat seal, claim heat sealing strength test value most
Big heat seal seam is optimal 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 excessively heat seal.
One those of ordinary skill is readily apparent that, the optimal heat seal parameter needed for can obtaining standard heat seal by experiment.Food
Product are packed with medical package field, particularly in blood product packaging bag manufacture field, plastic sheeting heat seal have 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 heat-seal temperature is maximum for the influence of heat sealing quality, and heat seal pressure and heat sealed time are to described
The influence of heat sealing quality is relatively small or negligible.
In packaging for foodstuff and medical package field, optimal heat-seal temperature is generally obtained with experimental method.Generally preset
One heat sealing strength receives standard (i.e. desired value), then heat seal of the method for testing specified according to authoritative standard to test specimen
Intensity is tested, and test result satisfaction receives standard and then assert that the heat-seal temperature is reasonable temperature or optimum temperature.For example it is right
In peelable packaging bag (the free-hand packaging bag torn during convenient use), generally according to American Society Testing and Materials《ASTM
F88 flexible barrier material sealing intensity test methods》Tested, dominant failure mode during sample test is shelled for heat seal region
From (Fig. 9), its test result is essentially identical to the true heat sealing strength of sample.And for bags of blood, bag filter etc. can not
Packaging bag (without the free-hand packaging bag torn when using) is peeled off, generally according to American Society Testing and Materials《ASTM
F2029 determines flexible material heat seal capability thermal weld code of practice by measuring sealing intensity》Tested, sample test
When dominant failure mode for heat seal region peel off (Fig. 9) or transitional region fracture (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, so as to cause local intensity significantly to drop
It is low.Failure mode when sample test for transitional region be broken when, its test result is strong less than the true heat seal of sample
Degree.But, as long as test result meets receives standard, still assert that the heat-seal temperature is reasonable temperature or optimum temperature.Should
Particularly point out, the establishment of the optimum temperature depends primarily on its method of testing and receives standard, therefore optimal heat-seal temperature
The heat sealing strength for being not intended that its heat seal seam is optimal.When heat sealing strength test failure mode for heat seal region peel off rather than
When transitional region is broken, and during heat seal region peeling force maximum, referred to as optimal heat seal, and the heat-seal temperature of its sample is called optimal
Heat-seal temperature, more accurately, commonly referred to as this optimum temperature parameter is theoretical optimum temperature or preferable optimum temperature.
When generally obtaining optimal 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 during actual production manufacture, due to film thickness error, film out-of-flatness, heat seal work folder
Tool error, the combined influence of unequal factor of being heated is more long with the poor material of sealability (for example especially for heat seal seam
Thermoplastic elastomer (TPE)), heat seal (welding) is carried out using theoretical optimum temperature and easily Local residues space, i.e. heat seal seam occurs
Sealing integrity is not up to standard.Or heat sealing performance poor product more long for heat seal seam, the sealing integrity of heat seal seam and
Heat sealing strength is conflicting, to ensure that sealing integrity generally has to that using excessively heat-sealing, i.e., heat sealing strength must be sacrificed.
In packaging for foodstuff and medical package field, the sealing integrity of its packaging is the most critical index must being fulfilled for, and heat sealing strength
It is secondary index.Packaging for foodstuff and medical package field are usual to meet sealing integrity as most critical index, in this premise bar
Relatively low heat-seal temperature is selected under part to obtain preferable heat sealing strength, the optimal heat-seal temperature that it is used is usually above theory most
Good temperature.When carrying out heat seal with this optimal 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 in the heat seal for laparoscope dedicated specimen of the present invention bag
The experience in packaging for foodstuff and medical package field is generally continued to use in the preceding specimen bag batch heat seal when manufacturing, i.e., using higher than theory
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 described specimen bag 100 in heat seal under the conditions of optimal heat-seal temperature, 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 causes the transitional region 132 local
It is significantly thinning, so as to cause local intensity to significantly reduce.
With reference to Fig. 4-5 and Figure 12-13, as it was noted above, specimen bag 100 and its pathological tissues for containing or organ 70 are passed through
When taking out by puncture cannula or via skin incision, because puncture cannula internal diameter or Minimally Invasive Surgery otch are smaller, specimen bag 100 is received
To very big extruding force, it is easily caused and takes thing bag rupture.And local excessive heat seal causes the intensity of transitional region 132 to significantly reduce
The risk of rupture of specimen bag 100, such as Figure 12-13 are just greatly increased, transitional region 132 is in the case of very big extruding force.
One those skilled in the art is readily apparent that increasing film thickness can increase the intensity of specimen bag, but when specimen bag is for preceding
State when taking in sundries tool, because the size of conduit is limited, increasing film thickness and typically resulting in specimen bag to be accommodated in conduit
Or specimen bag cannot be released from conduit.In view of the size-constrained system of film thickness, and be subjected to very during specimen bag clinical practice
Big extruding force, therefore be no upper limit for the pursuit of specimen bag intensity, intensity is the bigger the better.Simultaneously as specimen bag
It is generally used for containing pathological tissues or organ, its sealing integrity is also of equal importance, and any leakage may all increase patient
The risk of inadvertent contamination or the workload of the follow-up cleaning treatment of increase.Obtain the hot bonding method of sealing integrity and obtain optimal heat
The hot bonding method for closing intensity is conflicting, up to the present also solves this conflict without good method, and sample
The case ruptured in bag clinical practice still happens occasionally.
In order to be better understood from embodiment scheme disclosed by the invention, look back described previously using heating welding first herein
(heat seal) legal system makes underheat conjunction during specimen bag, standard heat seal and excessive heat seal situation, and obtains maximum heat using test method(s)
The method for closing intensity, optimal heat seal seam and theoretical optimum temperature.One those skilled in the art is it is contemplated that different material
Material, or the different thickness of similar material, or same type of material same thickness but different hardness, the maximum heat seal obtained using experimental method
The difference of intensity, optimal heat seal seam and theoretical optimum temperature is very big, therefore not for a certain specific material in the present invention
A certain concrete case is studied.
During using other welding manners, differ primarily in that the source of welding energy is different, it is essential identical that it is welded.Adopt
Manufacture specimen bag with other welding manners, the film that is welded to each other be also in the molten state, film by heat seal region
The polymer segment phase counterdiffusion on surface, infiltration, mutually winding so that biplate (or multi-disc) film is welded together.Specimen bag
Also film substrate, transitional region and welding area can finer be divided into.During film heat seal, in the effect of heat seal pressure
Under, the film in molten condition in heat seal region is calendered extrusion, so as to form the transitional region.The transitional region
Film thickness less than the film substrate thickness.Its solder joint also can be approximate the deficient welding that is divided into (be equal to underheat
Close), standard welding (be 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 of its influence welding quality is different, using different welding parameters, determines welding
Seam belongs to deficient welding, standard welding or excessively welding.Equally, other known welding manners, it is also possible to by experimental method
The maximum weld strength of acquisition, optimal solder joint and theoretical optimal 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, influence the factor of its solder joint quality widely different, but can using identical method of testing 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, at this, the term related to specimen bag solder joint quality is defined as below：
Owe welding：That is the thinner thickness of film that the surface of welding region is melted, participating in fusion, when weld strength is tested
Failure mode is peeled off for the welding area of specimen bag, and test result is less than desired value.
Standard welding：That is the thickness of film that the surface of welding region is melted, participating in fusion is moderate, and weld strength is surveyed
Failure mode during examination is the welding area stripping of specimen bag, and test result reaches desired value.
Excessive welding：That is the thickness of film that the surface of welding region is melted, participating in fusion is too many, causes specimen bag
The thickness of the transitional region between welding area and bag transition region is significantly thinning, and failure mode when weld strength is tested is
Transitional region is broken, and heat sealing strength test result is less than desired value.
Owe fusion weld：Weld strength test shows as owing the weld seam of welding.
Standard fusion weld：Weld strength test shows as the weld seam of standard welding.
Excessive fusion weld：Weld strength test shows as the weld seam of excessive welding.
Optimal weld seam：Failure mode when weld strength is tested is that the welding area of specimen bag is peeled off, and test result reaches
To the weld seam of maximum.Theoretical optimal welding parameter：Obtain welding parameter during optimal weld seam.
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, need that sample is prepared into the banding test specimen that width is 1in, 25mm or 15mm in advance.It is tested with weld seam long
After sample is prepared to multiple banding test specimens, its test result may be included and owe welding, standard welding and excessive welding,
It is mixing weld seam that this defines such weld seam long.
Owe welding and standard welding mixing weld seam：Simultaneously comprising deficient weld and standard weld in same weld seam.
Standard welding and excessive welding mixing weld seam：Standard weld and excessive weld portion are included in same weld seam simultaneously
