Description

指针件及设有该指针件的圆管型吻合器 Pointer member and is provided with the stapler tube member pointer

技术领域 FIELD

[0001] 本发明涉及一种指针件及设有该指针件的圆管型吻合器,属于医疗器械技术领域。 [0001] The present invention relates to a device and a pointer is provided with the stapler tube member pointer, a medical instrument technical field.

背景技术 Background technique

[0002] 圆管型吻合器是对消化道等生理组织进行外科手术时经常使用的一种医疗器械。 [0002] stapler tube is a medical instrument frequently used for gastrointestinal tract and other biological tissue of a surgical procedure. 这类吻合器大多采用轴向内装订方式,吻合时两段组织内敛,在组织内部形成圆形吻合环,该器械可使手术过程中产生的机体出血能随着内容物一起排出,手术后集体组织比较容易愈合。 Such stapling bookbinding mode axially inner most part, when the two stapling tissue restrained, form a circular anastomosis ring within the tissue, the surgical instrument can body produced during bleeding can be discharged along with the contents after the operation of collective the organization is relatively easy to heal.

[0003] 现有地,用于治疗痔疮的圆管型吻合器包括吻合器本体、活动连接所述吻合器本体的操作把手以及与所述本体配合的砧组件。 [0003] In the conventional manner, for the treatment of hemorrhoids stapler tube operating knob comprises a stapler body, active body is connected to the stapler and the anvil assembly cooperating with said body. 所述吻合器本体包括设于远端的环形钉仓、切刀。 The stapler includes a body provided at a distal end of the annular staple cartridge cutter. 所述砧组件包括圆台状的钉砧,及固定在其顶部的钉砧帽、设置在钉砧内部的刀砧,和与吻合器本体可拆卸地连接的钉砧轴。 The anvil assembly comprises a truncated cone-shaped anvil, and a fixed anvil at the top hats, the anvil shaft is provided inside the anvil knife anvil and a stapler main body is detachably connected.

[0004] 一般地,在进行痔疮切割吻合术时,先手动或使用扩肛器座等辅助器械进行扩肛,针对痔疮组织进行扎荷包后,将圆管型吻合器插入肠道,然后将荷包线通过圆管型吻合器钉筒内的通道拉出器械并收紧,此时痔疮组织便被收紧在钉筒内和钉砧之间,拉近砧组件的钉砧使钉砧和和吻合器本体的钉仓夹紧内敛的痔疮组织,然后,通过操作把手控制钉仓和切刀进行击发,以将痔疮组织进行吻合、切割,最后,在器械击发完成后,将圆管型吻合器由肠道中抽出。 When [0004] Generally, during the cutting anastomosis hemorrhoids, anal or to manually mount auxiliary equipment for anal, after Zhahe packet for hemorrhoid tissue, the stapler is inserted into the intestinal tube, and then the purse line drawn through the tube staple stapler instrument channel barrel and tightened, this time will be tightened hemorrhoid tissue between the cartridge and the staple anvil, the anvil assembly closer to the anvil so that the anvil and stapling and clamping the cartridge body tissue restrained hemorrhoids, then, by operating the handle control for firing the staple cartridge and knife to the hemorrhoid tissue stapling, cutting, and finally, after the firing of the instrument was completed, the stapler by a tube intestinal withdrawn. 然而,在将圆管型吻合器插入肠道等生理组织时,操作者在做击发准备的过程中,可能会无意识地握持住操作把手,使得操作把手抵住指针件而导致指针不动情况的发生,从而使操作者无法正确判断器械是否已到达可击发位置,这极有可能导致在未做好击发准备的情况下,按压操作把手触发钉仓和切刀进行击发,造成医疗事故。 However, when the biological tissue is inserted into the stapler tube intestine, an operator in doing cocked, it may be unconsciously grip the operating handle, such that the operating handle against the member caused by the pointer does not move the pointer where occurs, so that the operator can not judge whether the equipment has reached the correct position can be fired, which is likely to cause in the absence of well cocked, the trigger is pressed the operating handle and blade cartridge were fired, resulting in medical malpractice.
