吻合器钉砧组件及吻合器 Stapler anvil assembly and stapling

技术领域 FIELD

[0001]本发明涉及外科手术用医疗器械技术,尤其涉及一种吻合器钉砧组件及吻合器。 [0001] The present invention relates to medical devices for surgical technique, particularly to a stapler anvil and the stapler assembly.

背景技术 Background technique

[0002] 世界上首例吻合器用于胃肠吻合已近一个世纪,直到1978年管型吻合器才广泛用于胃肠手术,吻合器也叫切割缝合器。 [0002] the world's first case of gastrointestinal anastomosis stapler for nearly a century, until 1978, stapler tube was widely used in gastrointestinal surgery, also known as stapler stapler. 一般分为一次性或多次使用的吻合器,它是医学上使用的替代传统手工缝合的设备,由于现代科技的发展和制作技术的改进,目前临床上使用的吻合器质量可靠,使用方便,严密、松紧合适,尤其是其缝合快速、操作简便及很少有副作用和手术并发症等优点,有时还使得过去无法切除的肿瘤手术得以病灶切除,很受国内外临床外科医生的青睐和推崇。 Generally divided into one-time or multiple use stapler, it is an alternative to the traditional manual suturing devices used in medicine, due to improvements in modern technology development and production technology, currently used in clinical stapler reliable, easy to use, tight, snug fit, especially its suture fast, easy to operate and very few side effects and advantages of surgical complications, sometimes making the past unresectable tumors is excision, very popular with domestic and foreign clinical surgeon's favor and respected.

[0003]吻合器的性能差异对整个手术效果起着至关重要的作用,目前吻合器大多采用轴向内装订方式,主要包括钉砧组件、钉匣组件、用于击发钉匣组件中的缝钉的击发装置和器身,钉匣组件和击发装置设置在器身上,钉砧组件与击发装置可拆卸地连接,这里提供一种常用的连接结构,参见图1-3,钉砧杆底部呈梭状,梭状部上方具有一卡槽,该梭状部穿过器身内部击发装置的卡孔,该卡孔通过一弹性部件能够在梭状部卡入其内时发生弹性扩张变形,待卡槽插入卡孔中与其配合后卡孔通过该弹性部件能发生弹性收缩变形,使得钉砧杆与击发装置连接在一起;钉匣组件内安装有缝钉,击发装置用于击发钉匣组件内的缝钉,使其与钉砧组件配合完成缝合,装订时首先将两段组织待连接的端部均放置于钉砧组件与钉匣组件之间,通过击发装置的击发,钉匣组件 Performance difference [0003] stapler plays a vital role in the overall effects of surgery, using the most current stapler axially binding mode, including the anvil assembly, the magazine assembly for firing the staple cartridge assembly seam staple firing means and the body, the staple cartridge assembly and the firing mechanism is disposed on the body, the anvil assembly means detachably connected with the firing, there is provided a common connecting structure here, referring to FIGS. 1-3, showing the bottom of the anvil rod Clostridium, Clostridium upper portion having a slot, the card passes through the hole portion of the spindle inside the body of the firing device, the card through a hole into the elastic member can be deformed elastically expandable spindle when it occurs within the card portion to be the card slot after insertion hole mated engaging hole of the elastic member elastically deformable shrinkage can occur through, so that the anvil rod connected with the firing means; staples mounted within the staple cartridge assembly, the firing means for firing the staple cartridge assembly staples, the anvil assembly so that it is completed with the stapling, the stapling tissue two first end portions to be joined are placed between the anvil assembly and the staple cartridge assembly, the firing of the firing, the magazine assembly 内环形布置的缝钉与钉砧组件配合产生变形,将两段组织装订在一起,在组织内部形成一个闭合的装订环,但是,由于装订后钉砧组件和钉匣组件分别位于装订环的两侧,取出钉砧组件时必须经过装订环,但是,钉砧组件的最大直径大于装订环的内径,所以在术后取出钉砧组件必定要触及装订环,甚至会破坏装订环的形状,这种现象不利于术后机体组织的回复,易导致手术并发症,副作用大,降低了手术效果。 Inner annular arrangement of staple deforming anvil assembly with the two tissues bound together to form a binder ring closed within the tissue, but, due to the anvil assembly and staple cartridge assembly after the binding rings are respectively located two binding side, the binding ring must be removed when the anvil assembly, however, the maximum diameter of the anvil assembly is greater than the inner diameter of the ring binding, the anvil assembly so removed must be accessible after the binding ring, or even destroy the shape of the binding ring, such phenomenon is not conducive to reply after body tissue, easily lead to surgical complications, side effects and reduce the effect of surgery.

[0004]针对以上情况,现有技术采用了可翻转结构的钉砧组件,即钉砧相对钉砧杆可翻转,在取出过程中通过钉砧的翻转降低对装订环形状的破坏程度,并达到手术效果,现有技术如下: [0004] For the above, the prior art uses a structure of the anvil assembly may be inverted, i.e., the anvil opposing anvil rod reversible reduce the level of damage to the shape of the binding rings by flipping the anvil in the extraction process, and to achieve results of operations, the following prior art:

[0005] 现有技术一 [0005] a prior art
