背景技术 Background technique

各种消化道管型吻合器正在外科手术中被广泛地用于吻合人体消化道组织,可以减少手术时间,提髙手术质量。 Various gastrointestinal tube stapling surgery is being widely used to match the human digestive tract tissue, can reduce the operation time, improve the quality of Gao surgery. 它们通常被用于消化道中食管、胃、十二指肠、小肠、结肠和直肠等端端、端側及糊惻吻合手术,特别适用于显露和操作困难的胃胸顶部的食管端端吻合和低位直肠癌切除后结肠直肠低位端端吻合等手术,还适用于痔核切除和背幽门造口等在器官内形成管形通道的手术。 They are usually used in the digestive tract esophagus, stomach, duodenum, small intestine, colon and rectum end to end, side and end anastomosis sad paste, particularly suitable for esophageal end to end and reveal the top of a difficult operation stomach stapling and chest after resection of colorectal cancer lower colorectal anastomosis low, such as surgery, but also for removal of hemorrhoids and other surgical stoma back pyloric passage formed in the tubular organ.

美国专利431诉76、 4603693 、 5193731和5350104中介绍的消化道管型吻合器,包 V. U.S. Patent No. 76 431, 4,603,693, 5,193,731, and 5,350,104 digestive tube type stapler described, package

括颈部呈直形的或弯形的吻合器身,安装在吻合器身头部的固定的或可装卸的钉筒,安装在钉筒前端的可装卸的钉砧,安装在吻合器身躯部的可枢轴转动的击发手柄,安装在击发手柄旁的保险机构,安装在吻合器身尾部的调节旋钮,安装在吻合器身躯部的钉砧位置指示机构,安装在吻合器身内部的钉砧拉杆、推钉杆和其它辅助零部件.在钉筒内装有吻合钉、推钉座和环形刀。 The neck portion including a straight or curved shape of the stapler body, fixed or removable staple cartridge mounted in the stapler body head, mounted on the front end of the cartridge and anvil may be detachably mounted in the stapler body portion an anvil pivotable firing handle mechanism is mounted next to the insurance of the firing handle, knob mounted on the tail of the stapler body, an anvil mounted in the position indicating mechanism of the stapler body portion, installed inside the stapler body rod, pushing the shank and other ancillary components. cylinder with staples in the staple, the staple holder and pushing the annular cutter. 吻合钉在钉筒圆形前端部的钉仓内沿周向排列。 Staples arranged circumferentially within the circular staple cartridge distal tubular portion. 钉砧在与钉筒相对的端面上,与钉倚内的吻合钉位置对应地排列有吻合钉成形槽,与钉简内的环形刀位置对应处装有刀砧。 The anvil and the staple cartridge on the end face opposite to, staple forming grooves arranged to correspond to the position of the staple within staple lean, the annular cutter at a position corresponding to the inner profile with staple anvil blade. 转动调节旋钮,即可通过據旋机构移动钉砧拉杆,使钌砧相对钉筒前后移动。 Turning the volume control, according to a spin mechanism by moving the anvil rod, the anvil ruthenium move back and forth relative to the staple cartridge. 打开保险机构,即可夹紧击发手柄向前推动推钉杆,通过钉筒内的推钉座将钉筒内的吻合钉和环形刀推出。 Open insurance agencies, the firing handle to the clamping shank by pushing the push forward by pushing the staple anvil cylinder barrel nail and staple annular knife Release. 吻合钉可采用不锈钢丝、钽丝、钛丝或其它具有类似性能的金属丝制造。 Staple wire can be stainless steel, tantalum wire, titanium wire or other metal wire manufactured having similar properties.

在使用消化道管型吻合器时,首先将消化道管型吻合器插入待吻合组织,然后转动调节旋钮使钉砧向前移动,以便将待吻合组织扎紧在钉砧和钉简之间的钉砧拉杆上。 When using the stapler gastrointestinal tube is first inserted into the stapler gastrointestinal tube tissues to be stapled, and then turn the knob so that the anvil moves forwardly, so that the fastened tissue to be stapled between the anvil and the staple Jane lever on the anvil. 此时再以相反方向转动调节旋钮,同时观察指示机构,使钉砧与钉筒之间达到所需的夹紧厚度。 At this time, then the adjustment knob is rotated in the opposite direction, while observing the indicating means, so that to achieve the desired thickness of the clamping between the anvil and the staple cartridge. 待组织被夹紧后打开保险机构,即可夹紧击发手柄推出钉筒内的吻合钉和环形刀。 Insurance agencies tissue is to be opened after clamping, gripping the firing handle to the staple launch tube and the annular staple cutter. 当吻合钉被从钉筒内推出后,即穿透被夹紧的待吻合组织直抵钉砧上的成形槽,使u形的吻合钉弯曲成B形,达到将组织吻合的手术目的。 When the staple is pushed from the staple cylinder, i.e. penetrating tissue to be stapled is clamped straight grooves formed on the anvil, so that the u-shaped bent into a B-shaped staples, tissue to achieve the purpose of surgical anastomosis. 当环形刀被从钉筒内推出后直抵钉砧内的刀砧上,切除被夹紧的待吻合组织的多余部分。 When the annular blade is straight from the anvil after the staple anvil cylinder Release knife, cut the clamped tissue to be stapled excess portion. 完成吻合操作后,转动调节旋钮使钉砧与钉筒间距增大,松开已吻合组织,以便退出消化道管型吻合器。 After completion of the stapling operation, rotation of the adjustment knob to the anvil and the staple cartridge spacing increases, release the stapled tissue, gastrointestinal tube to exit the stapler.

临床使用的消化道管型吻合器有重复性使用的和一次性使用的两种。 Gastrointestinal tube stapler clinical use there and two types of single-use repetitive use. 重复性使用的消化道管型吻合器的功能少,每次使用后需拆卸、清洗、消毒和再装配,既影响器械的性能,又易引起交叉感染。 Gastrointestinal tube stapler less repetitive use functions demolition required after each use, cleaning, reassembly and sterilization, only affects the performance of the device, and can lead to cross-infection. 由于塑料工业的发展,大量适合医用的质优价廉的塑料被开发出来,促进了各种一次性使用的外科器械蓬勃发展,并在临床获得广泛使用。 Since the development of the plastics industry, for a large number of medical quality and cheap plastic was developed to promote a variety of single-use surgical instruments to flourish, and widely used in clinical. 由T^ 管、胃和肠等消化道器官的发病率很髙,这些管形器官的手工吻合又很困难,手术质量难以保证,因此一次性使用的消化道管型吻合器是目前临床使用量最大的一种一次性使用的外科器械。 The incidence of the tube T ^, stomach and intestines and other organs of the digestive tract is Gao, these artificial anastomosis of tubular organs very difficult, is difficult to guarantee the quality of surgery, gastrointestinal tube so disposable stapler is currently clinically used in an amount a disposable surgical instrument for use maximum. 虽然临床使用一次性使用的消化道管型吻合器可降低手术中的交叉感染,但生产成本较高。 Although tubular gastrointestinal clinical use disposable stapler may reduce cross-contamination of surgery, but the high production costs. 美国专利5271544和6193129中介绍的一次性使用的消化道管型吻合器中有大量的金加工零件和注塑零件.而冲压零件较少。 U.S. Patent No. 5,271,544 and 6,193,129 in the digestive tube of the disposable type stapler described in a large number of metal processing parts and molded parts. Stamping parts and less. 这种式样的消化道管型吻合器的令人不满意处是,由于一次性使用的消化道管型吻合器是大规模生产的医疗器械,其中金加工零件的生产成本大f注塑零件,注塑零件的生产成本大于冲压零件,因此一次性使用的消化道管型吻合器的生产成本还需降低。 Unsatisfactory at this style of gastrointestinal tube stapler, due to gastrointestinal tube stapler disposable mass production of medical devices, metal processing which parts of the production cost big f injection-molded parts, injection parts, the cost is greater than stamped parts, the production cost of the digestive tube type disposable stapler needs to be reduced. 目前, 一次性使用的消化道管型吻合器的大部分零件由塑料制成,塑料零件与塑料零件之间的连接,塑料零件与金属零件之间的连接对一次性使用的消化道管型吻合器的质量和成本有很大的影响。 Currently, most of the parts of the digestive tube type disposable stapler is made of plastic, gastrointestinal-type tube connection between the connection between the plastic part and the metal part and the plastic part of the plastic part a disposable stapling quality and cost control have a great impact. 美国专利5271544中所介绍的一次性使用的消化道管型吻合器,其吻合器身躯部由塑料制成的左、右吻合器身合拢后釆用超声波焊接而成,其弯颈部采用金属弯管制成,金属弯管的两端分别通过金属套管与塑料制成的钉筒和吻合器身滚压连接。 Gastrointestinal tube type disposable stapler U.S. Patent 5,271,544 in the introduction, which stapler body made of plastic of the left and right rear body stapling preclude collapse ultrasonically welded, which bent metal bent neck tubing, the staple cartridge and the stapler body roll bending both ends of the metal sleeve and the metal respectively connected plastic. 这种式样的一次性使用的弯颈式消化道管型吻合器的令人不满意处是,由于金属弯管与塑料制成的左、右吻合器身的强度相差很大,塑料件在受力状态下有瞎变的趋势,很难达到满意的连接效果。 Unsatisfactory at this style curved neck tube gastrointestinal stapler is disposable, since the left elbow made of a metal and plastic, the strength of the right stapler body differ greatly, under the plastic member has become the trend of blind force under the state, it is difficult to achieve satisfactory results connected. 另外,金属弯管内部难以加工成较复杂的形状,现有的消化道管型吻合器的钉砧拉杆和推钉杆在弯颈内部都是叠在一起安装的,使用时会相互摩擦和挤压,既增加钉砧拉杆和推钉杆移动阻力又降低移动精度。 Further, inside of the metal bend is difficult to process into a more complex shape, a conventional digestive tube stapler anvil and the push rod inside the shank Tolypocladium are installed stacked together, each will use friction and squeeze pressure, increasing both the anvil and the push rod and reducing resistance to movement of the shank movement accuracy. 美国专利5685474 中所介绍的一次性使用的消化道管型吻合器,其吻合器身由塑料制成的左、右吻合器身合拢而成,左、右吻合器身采用金属蠊钉和铆钉连接在一起。 Gastrointestinal tube type disposable stapler in U.S. Patent No. 5,685,474 described, left a stapler body which is made of plastic, closed from the right stapler body, left and right metal stapler body and rivets connecting cockroach together. 这种式样的一次性使用的消化道管型吻合器的令人不满意处是,由于金属瞎钉和铆钉与塑料制成的左、右吻合器身的强度相差很大,塑料件在受力状态下有蠕变的趋势,很难达到满意的连接效果。 Unsatisfactory at this style stapler gastrointestinal tube is disposable, since the metal left blind rivet made of a staple and a plastic, the strength of the right big difference stapler body, force the plastic member there is a tendency to creep under the state, it is difficult to achieve satisfactory results connected. 上述两种美国专利中所介绍的一次性使用的消化道管型吻合器,由塑料制成的推钉座与金属环形刀采用超声波焊接达到连接的目的,钉筒外壳与钉仓采用粘接达到连接的目的。 Gastrointestinal tube type disposable stapler above two U.S. patents described, made of plastic with a metal ring to push anvil blade employed to achieve the object of the ultrasonic welding connection, a staple cartridge and the staple cartridge housing using an adhesive to achieve the purpose connected. 这两种式样的一次性使用的消化道管型吻合器的令人不满意处是,超声波焊接的连接精度与设备、技能和零件的形状有关、加工时间较长,而粘接剂会流入不需要粘接的部位、 还对环境有污染;另外,超声波焊接和粘接的质量与被连接的材料的化学成分、熔点、 摩擦系数、硬度、表面特性和结构形状等化学性能和物理性能有关,从而大大减少了材料的选择范围,可能难以找到最合适的材料。 These two designs are unsatisfactory at stapler gastrointestinal tube is disposable, ultrasonic welding precision and shape of the device is connected, and the part of the relevant skills, longer processing time, the adhesive agent does not flow into bonding portion need further pollution of the environment; Moreover, the quality of the ultrasonic welding and bonding with the chemical and physical properties, chemical composition, melting point, coefficient of friction, hardness, surface material properties, and structural shapes and the like are connected to related, thus greatly reducing the choice of material, it may be difficult to find the most suitable material. 因此-次性使用的消化道管型吻合器的^ 料零件与塑料零件之间的连接、塑料零件与金属零件之间的连接还需改进。 Thus - the connection between the connector, the plastic part and the metal part and the plastic part between the feed tube parts gastrointestinal stapler secondary ^ of use should be improved. 当待吻合组织被夹紧后再夹紧击发手柄推出钉筒内的吻合钉时,外科医生往往霈要了解U形的吻合钉是否已被弯曲成B形将组织吻合。 When tissue to be stapled is clamped after clamping anastomosis staple firing handle Release barrel, the surgeon often Pei To learn if the U-shaped staple has been bent into a B-shaped tissue anastomosis. 美国专利5685474中介绍的消化道管型吻合器,当击发手柄通过推钉杆推出钉筒内的吻合钉时,推钉杆在吻合器身内向前 Gastrointestinal tube type stapler described in U.S. Patent No. 5,685,474, when the firing handle Release anastomosis staple within the cartridge by pushing the shank, the shank pushes forward the stapler body

移动;当U形的吻合钉己被弯曲成B形将组织吻合时,推钉杆将吻合器身内的--根金属杆挤断,金属杆断裂时发出的声音提示外科医生:U形的吻合钉已被弯曲成B形将组织吻合。 Movement; when the U-shaped staple has been bent into a B-shaped tissue anastomosis staple pushing rod inside the stapler body - squeeze off the root metal rods, metal rods breaking sound of the surgeon Tip: U-shaped anastomosis the staple has been bent into a B-shaped tissue anastomosis. 这种式样的消化道管型吻合器的令人不满意处是,挤断金属杆霈要消耗外科医生. 较大的夹紧击发手柄的力,并且金属杆断裂的位置也不很准确。 Unsatisfactory at this style stapler gastrointestinal tube is squeezed off the metal rod Pei consumed surgeon. Greater clamping force of the firing handle, metal rods and fracture location is not very accurate. 美国专利5271544和6193129中介绍的消化道管型吻合器,当U形的吻合钉被弯曲成B形将组织吻合时,环形刀将钉砧内的刀砧切断,刀砧断裂时发出的声音提示外科医生:U形的吻合钉已被弯曲成B形将组织吻合。 U.S. Patent No. 5,271,544 and 6,193,129 digestive tube type stapler described, when the U-shaped staple is bent to match the tissue type B, the annular knife blade of the anvil in the cutting anvil, voice prompts issued when the knife anvil break surgeon: U-shaped staple has been bent into a B-shaped tissue anastomosis. 这种式样的消化道管型吻合器的令人不满意处是,刀砧断裂时发出的声音大小与刀砧材料的硬度和切断的速度有关,即清晰的断裂声音需要消耗较大的力,并且刀砧断裂的位置与吻合钉被弯曲成B形的位置也不完全对应。 Unsatisfactory at this style of digestive tube type stapler, the sound emitted when the size of the knife and the cutting anvil at break and the hardness of the material about the anvil blade speed, i.e., clear voice breaking consumes a large force, knife anvil and break the position of the staple is bent to a position corresponding to B is not entirely formed. 因此…次性使用的消化道管型吻合器的吻合完成的声音提示机构还需改进。 So ... anastomosis stapler gastrointestinal tube of times of use of voice prompts to complete the agencies need to improve.

消化道管型吻合器的通过击发手柄推出吻合钉和环形刀执行组织吻合的击发机构H 前已有几种式样。 H before firing by a firing mechanism of the handle of the stapler digestive tube Release annular knife and staple tissue anastomosis performed several patterns. 美国专利5271544中介绍的消化道管型吻合器,环形刀切割刀砧的作用处为完整的圆周。 Gastrointestinal tube type stapler described in U.S. Patent No. 5,271,544, the action of the annular cutting knife blade of the anvil for a complete circumference. 这种式样的消化道管型吻合器的令人不满意处是,当击发手柄通过推钉杆推出钉筒内的吻合钉和环形刀执行组织吻合时,大部分的力消耗在环形刀切割刀砧上。 Unsatisfactory at this style of digestive tube type stapler is pushed when the firing handle shank Release by the staples within the cartridge and staple tissue annular cutter performing anastomosis, in most of the force is consumed by the annular cutting blade knife anvil. 美国专利6193129中介绍的消化道管型吻合器,环形刀的刀刃为曲线状,环形刀切割刀砧的开始作用处为环形刀的刀刃的波峰,可减少环形刀切割刀砧的作用力。 Gastrointestinal tube type stapler described in U.S. Patent No. 6,193,129, the annular knife blade is curved, onset of action of the annular cutting blade knife anvil crest annular knife blade, the knife cutting force can be reduced annular knife anvil. 这种式样的消化道管型吻合器的令人不满意处是,曲线状刀刃的环形刀很难制造。 Unsatisfactory at this style stapler gastrointestinal tube is curved annular knife blade is difficult to manufacture. 上述两种式样的消化道管型吻合器的另一令人不满意处是,当击发手柄通过推钉杆推出钉筒内的推钉座和环形刀执行组织吻合时,推钉座和环形刀随击发手柄的夹紧和放松而前后移动, 一旦外科医生在夹紧击发手柄用力困难时放松一下,则推钉座和环形刀也随着后移, 此时U形的吻合钉未被弯曲成B形将组织吻合,环形刀也未将多余的组织切除。 Another unsatisfactory at both style digestive tube type stapler is pushed when the firing handle is introduced through the shank to push the staples within the cartridge and the annular knife anvil tissue anastomosis performed, and annular knife anvil pushing with the tightening and loosening of the firing handle moves back and forth once while the surgeon to relax the clamping force of the firing handle is difficult, and annular knife anvil pushes along with the move, when the U-shaped staples are not bent in B-shaped tissue anastomosis, the annular cutter has not cut the excess tissue. 如果外科医生再次夹紧击发手柄时,推钉座和环形刀可能不再作用在原来的位置上,造成不完整的吻合钉成形和不完整的组织切除。 If the surgeon gripping the firing handle again, pushing the annular cutter and the anvil can no longer acting in the original position, resulting in incomplete staple forming and incomplete tissue removal. 美国专利5685474中介绍的消化道管型吻合器, 当击发手柄通过推钉杆推出钉筒内的推钉座和环形刀执行组织吻合时,推钉座和环形刀随击发手柄的夹紧和放松只向前移动而不向后移动。 U.S. Patent No. 5,685,474 tightening and loosening of the gastrointestinal tube type stapler described, when the firing handle to push the staples within the cartridge and the annular knife anvil tissue anastomosis performed by pushing the shank Release, pushing annular knife anvil and firing handle with only move forward and not backward. 这种式样的消化道管型吻合器的令人不满意处是,完成吻合操作后推钉座和环形刀凸出钉筒,会损伤周围的组织。 Unsatisfactory at this style of digestive tube type stapler is pushed stapling operation after the completion of the annular knife anvil and a staple cartridge projection, surrounding tissue may be injured. 因此消化道管型吻合器的击发机构还霈改进。 Thus firing mechanism gastrointestinal tube Pei stapler further improved.

完成吻合操作后,由于钉砧的面积大于吻合口的面积,消化道管型吻合器从吻合n After completion of the stapling operation, since the anvil is larger than the area of ​​the anastomosis, gastrointestinal anastomosis tube stapler from n

退出比较困难,可能会撕裂吻合口。 Exit more difficult, it could tear anastomosis. 消化道管型吻合器的钉砧倒倾转动机构目前已有几种式样。 Anvil stapler gastrointestinal tube is inverted rotating mechanism there are several styles. 在美国专利5639008中介绍的消化道管型吻合器,钉砧与钉砧拉杆之间采用枢轴连接,钉砧内有一弹簧盘卡住钉砧拉杆使钉砧不能绕钉砧拉杆侧倾转动:当进行吻合操作时,钉筒中的环形刀内侧的推杆将弹簧盘推开,以便在钉砧内的弹簧推动下使钉砧能绕钉砧拉杆侧倾转动。 In U.S. Patent No. 5,639,008 in the gastrointestinal tube type stapler described, using the pivotal connection between the anvil and the staple anvil rod, a spring plate so that the jammed staple anvil rod can anvil roll rotates about an anvil rod within the anvil: when the stapling operation, the staple pusher inside the annular knife cylinder will push the spring plate, so that the spring urges the anvil in the anvil roll can be rotated about the anvil rod. 由f俩倾转动后的钉砧在垂直f钉砧拉杆轴线方向的截面积小于吻合口的截面积,使消化道管型吻合器的钉砧容易从吻合口退出。 After the rotation of the anvil readily poured from the exit cross-sectional area f f both the anvil rod perpendicular to the axial direction is smaller than the cross sectional area of ​​the anastomosis, gastrointestinal tube makes stapler anvil from the anastomosis. 这种式样的消^fcil 管型吻合器的令人不满意处是,钉筒中的环形刀内侧的推杆在钉筒内占有--定的空间,减少了可容纳待吻合组织残段的空间;另-方面,钉砧内的弹簧盘和弹簧及钉筒内的推杆暴露在待吻合组织的残段处,待吻合组织残段会影响弹簽盘、弹貧和推杆的正确动4乍。 This pattern erasing ^ unsatisfactory at fcil tubular stapler that staples inner annular knife pusher cylinder barrel occupies the staples - given space, reduces the space can accommodate be stapled tissue stump ; other - aspect, a spring and a spring plate cylinder and the staple pusher in the anvil to be exposed at the stub stapling tissue, tissue to be stapled check stub will affect the disc playing, playing and lean right movable pusher 4 first. 因此消化道管型吻合器的钉砧侧倾转动机构还需改进。 Thus the anvil roll rotating mechanism of stapler gastrointestinal tube should be improved.

消化道管型吻合器的钉砧位置指示机构目前已有几种式样。 Anvil position indicating mechanism gastrointestinal tube stapler there are several styles. 美国专利5639008中介绍的消化道管型吻合器,釆用在调节旋钮尾部的槽内显示钉砧拉杆尾部的方式以指示钉砧拉杆拉动钉砧达到夹紧待吻合组织的位置。 Gastrointestinal tube type stapler described in U.S. Patent No. 5,639,008, preclude the use of tail groove in the adjusting knob is displayed anvil rod end of the anvil to indicate a pull rod reaches the position of the anvil clamping tissue to be stapled. 这种式样的消化道管型吻合器的令人不满意处是,调节旋钮尾部的槽随调节旋钮的转动而不断改变方向,影响观察。 Unsatisfactory at this style of digestive tube type stapler that groove with the rear adjustment knob rotating knob while changing the direction of impact was observed. 在美国专承J 5271544和6193129中介绍的消化道管型吻合器,采用钉砧拉杆带动一根摆动指针,仅当钉砧拉杆拉动钉砧达到夹紧待吻合组织的位置时,摆动指针才会在吻合器身躯部上的指示窗【J中显露,放大指示夹紧厚度。 Gastrointestinal tube type stapler described in U.S. Patent 6,193,129 and J 5271544 bearing, the use of an anvil drive rod swing pointer, only when the anvil reaches the position of the anvil rod to pull the clamping tissue to be stapled, the pointer will wobble indicator window on the stapler body in section [J revealed, indicating an enlarged thickness of the clamping. 上述两种式样的消化道管型吻合器的令人不满意处是,当钉砧拉杆拉动钉砧未达到夹紧待吻合组织的位置时,指示机构不起指示作用, 外科医生无法知道钉砧拉杆拉动钉砧到达的具体位置,不便于决定执行中间过程的操作方式。 Unsatisfactory at both style stapler gastrointestinal tube that when pulling the lever anvil anvil does not reach the position of the clamping tissue to be stapled, the agency can not afford to instruct its indication, the surgeon can not know the anvil DETAILED pull rod reaches the position of the anvil, is not easy to decide to perform the intermediate operation mode process. 因此消化道管型吻合器的指示机构还需改进。 Thus indicating means gastrointestinal tube type stapler should be improved.

由上述显然可以看出,现在已经设计了大量不同式样的消化道管型吻合器,并且新的消化道管型吻合器的研制工作仍在继续,以便对每年世界上大量使用的消化道管型吻合器作进一步的改进,使得操作更方便、省力、可靠和正确,制造更便利,成本更低。 It is apparent from the above, we have now devised a number of different styles of gastrointestinal tube stapler and a new stapler gastrointestinal tube development work continues, in order to gastrointestinal tube extensive use of the world each year stapler further improvements, so that the operation more convenient and labor-saving, reliable and correct manufacturing more convenient and lower cost.
