外科缝切器的钉仓Staple Cartridges for Surgical Cutters

技术领域technical field

本实用新型涉及一种外科手术器械的钉仓，尤其涉及一种外科缝切器的钉仓，属于医疗器械技术领域。The utility model relates to a staple magazine of a surgical instrument, in particular to a staple magazine of a surgical suture cutter, which belongs to the technical field of medical instruments.

背景技术Background technique

外科装订器械是用于外科手术中进行伤口缝合的重要工具，目前已有淘汰手工缝合的趋势。其中，如美国专利US7055730揭示的侧侧型外科缝切器可以在进行伤口闭合的同时进行组织切割。这种外科缝切器可以同时在组织的两侧各击入两排吻合钉，然后用切刀在两侧已缝合好的组织之间进行切割离断。目前临床广泛应用这种缝合器进行胃、空肠侧侧吻合，以及胃管的制作、肺部分切除等手术。Surgical binding instruments are important tools for wound suturing in surgical operations, and there is a trend of eliminating manual suturing at present. Among them, as disclosed in US Patent No. 7,055,730, the side-type surgical stapler can cut tissue while closing the wound. This surgical stapler can drive into two rows of staples on both sides of the tissue at the same time, and then use a cutter to cut and separate the sutured tissues on both sides. At present, this stapler is widely used clinically for side-to-side anastomosis of the stomach and jejunum, as well as operations such as the production of gastric tubes and partial lung resection.

但是由于现有的该类器械在手术中对切刀两侧的组织都进行相同的缝合，导致那些需切掉的组织上也会有缝合钉的存在，造成了缝合钉的浪费。另外，由于医生一般会对切掉的组织进行进一步的医学检查，而带有缝合钉的组织不利于切片，不方便检查。However, because the existing instruments of this type perform the same suturing on the tissues on both sides of the cutter during the operation, there will be staples on the tissues that need to be cut off, resulting in a waste of staples. In addition, since doctors generally conduct further medical examinations on the excised tissues, the tissues with staples are not conducive to sectioning and inconvenient for inspection.

本实用新型将此专利所记载的内容作为现有技术进行引用。The utility model uses the contents recorded in this patent as prior art.

具体实施方式Detailed ways

本实用新型揭示了一种外科缝切器的钉仓10，如图1和图2所示的第一实施例，包括一钉仓面1，所述钉仓面1上垂直向内开设有切刀槽3，所述切刀槽3的两侧分别为组织缝合侧2和组织切掉侧4，所述组织缝合侧2和组织切掉侧4上分别均各自设有至少一排钉孔排，分别为第一钉孔21的排列以及第二钉孔41的排列。所述第一、第二钉孔排的排列轴线均平行于所述切刀槽3的轴线。The utility model discloses astaple cartridge 10 of a surgical sewing cutter. The first embodiment shown in FIG. 1 and FIG.Knife groove 3, the two sides of thecutter groove 3 are thetissue suturing side 2 and thetissue cutting side 4 respectively, and thetissue suturing side 2 and thetissue cutting side 4 are respectively provided with at least one row of nail hole rows , are respectively the arrangement of thefirst nail holes 21 and the arrangement of thesecond nail holes 41 . Arrangement axes of the first and second nail hole rows are parallel to the axis of thecutter groove 3 .

一般来讲，所述组织缝合侧2上都会设有相互交错的两排第一钉孔排21。与现有技术一样，所述第一、第二钉孔排均由一组钉孔沿其自身轴线等距均布，而且所述组织缝合侧2的两排第一钉孔排21相互交错的位置也与现有技术一致，外侧的第一钉孔排21的设置是为了防止设于内侧的第一钉孔排21的钉孔内的缝合钉在缝合后钉与钉之间的间隔产生渗血及吻合口漏。Generally speaking, two rows of firstnail hole rows 21 that are staggered with each other are provided on thetissue suturing side 2 . As in the prior art, the first and second rows of nail holes consist of a group of nail holes distributed equidistantly along their own axes, and the two rows of firstnail hole rows 21 on thetissue suturing side 2 are staggered with each other. The position is also consistent with the prior art, and the setting of the firstnail hole row 21 on the outside is to prevent the staples in the nail holes of the firstnail hole row 21 located on the inside from infiltrating the space between the nails and the nails after suturing. Blood and anastomotic leakage.

本例中，所述组织缝合侧2上设有三排所述的第一钉孔21的排列。这三排钉孔的轴线都与所述切刀槽3的轴线平行。位于所述组织缝合侧2上的第一钉孔排21的排列轴线到切刀槽3轴线的最小距离小于位于所述组织切掉侧4上的第二钉孔排41的排列轴线到切刀槽3轴线的最小距离。这样，组织切掉侧的第二钉孔排41与切刀槽之间间隔较远，手术中被切除的组织也会较多，适于医生对组织切片进行医学检查。另外，本例中，所述组织切掉侧4上设有一排第二钉孔排41，这样也减少了缝合钉的浪费，节省成本，并且也使整个钉仓的制造简单。In this example, three rows of thefirst nail holes 21 are arranged on thetissue suturing side 2 . The axes of the three rows of nail holes are all parallel to the axis of thecutter groove 3 . The minimum distance between the arrangement axis of the firstnail hole row 21 on thetissue suturing side 2 and thecutter groove 3 axis is smaller than the arrangement axis of the secondnail hole row 41 on thetissue cutting side 4 to the cutter The minimum distance of theslot 3 axis. In this way, the distance between the secondnail hole row 41 on the side where the tissue is removed and the cutter groove is far away, and more tissues will be removed during the operation, which is suitable for doctors to perform medical examination on tissue sections. In addition, in this example, a row of secondstaple hole rows 41 is provided on the tissue-removedside 4, which also reduces the waste of staples, saves cost, and also simplifies the manufacture of the entire staple cartridge.

第一实施例中，所述切刀槽3与所述钉仓面1的中心线相偏移。图3和图4揭示的本实用新型的第二实施例与第一实施例的区别仅仅在于所述切刀槽3在所述钉仓面1的中心线上。这样导致手术中被切除、并遗留在缝合钉外侧的组织更多，更方面医生选择检查。In the first embodiment, thecutter groove 3 is offset from the center line of the cartridge surface 1 . The difference between the second embodiment of the present invention disclosed in FIG. 3 and FIG. 4 and the first embodiment is only that thecutter groove 3 is on the center line of the staple cartridge surface 1 . This results in more tissue being removed during the operation and left outside the staples, making it easier for doctors to choose to check.

图5揭示的第三实施例与第一实施例的区别在于：所述组织切掉侧4上设有二排的第二钉孔排41。这样能很好地缝合被切掉的组织。The difference between the third embodiment disclosed in FIG. 5 and the first embodiment is that two rows of secondnail hole rows 41 are provided on thetissue cutting side 4 . This will suture the cut tissue nicely.

图6揭示了本实用新型的第四实施例，所述钉仓面1上垂直向内开设有相邻的第一切刀槽31和第二切刀槽32，所述第一切刀槽31和第二切刀槽32的外侧分别为组织缝合侧2和组织切掉侧4，所述组织缝合侧2和组织切掉侧4上分别均各自设有至少一排钉孔排，所述钉孔的排列轴线平行于所述第一切刀槽的轴线。本例中，所述组织缝合侧2上设有三排第一钉孔排21，所述组织切掉侧4上设有一排第二钉孔排41。位于所述组织缝合侧上的第一钉孔排21的排列轴线到第一切刀槽轴线31的最小距离小于位于所述组织切掉侧上的第二钉孔排41的排列轴线到第一切刀槽31轴线的最小距离。这样保证有足够的被切除的组织可以用于医学检查。Fig. 6 discloses the fourth embodiment of the present utility model, and the adjacent first cutting groove 31 and the second cutting groove 32 are opened vertically inwardly on the surface 1 of the staple cartridge, and the first cutting groove 31 and the outside of the second cutter groove 32 are respectively thetissue suturing side 2 and thetissue cutting side 4, and thetissue suturing side 2 and thetissue cutting side 4 are respectively provided with at least one row of nail hole rows, and the nails The arrangement axis of the holes is parallel to the axis of the first cutting groove. In this example, three rows of firstnail hole rows 21 are provided on thetissue suturing side 2 , and one row of secondnail hole rows 41 is provided on thetissue cutting side 4 . The smallest distance between the arrangement axis of the firstnail hole row 21 on the tissue suturing side and the first cutting groove axis 31 is smaller than the arrangement axis of the secondnail hole row 41 on the tissue cutting side to the first The minimum distance of the cutter groove 31 axes. This ensures that enough removed tissue is available for medical examination.

优选的，位于所述组织缝合侧上的第一钉孔排21的排列轴线到第一切刀槽31轴线的最小距离等于位于所述组织切掉侧上的第二钉孔排41的排列轴线到第二切刀槽32轴线的最小距离。这样手术中就能直接将位于第一切刀槽31和第二切刀槽32之间的组织切除下来，直接可以进行医学检查。Preferably, the minimum distance between the axis of arrangement of the firstnail hole row 21 on the tissue suturing side and the axis of the first cutting groove 31 is equal to the arrangement axis of the secondnail hole row 41 on the tissue cutting side Minimum distance to the second cutter flute 32 axis. In this way, the tissue between the first cutting knife groove 31 and the second cutting knife groove 32 can be directly removed during the operation, and medical examination can be directly performed.

本文所有揭示的实施例还有一个共同的特点，所述组织缝合侧2的钉仓面呈阶梯状，即所述最外侧的钉仓面的高度低于所述最内侧钉仓面的高度，具体如图2和图4所示。这样设置可以使钉的成型形状不一，能使缝合组织得到更好的充血，有利于组织的愈合。All the embodiments disclosed herein also have a common feature, the staple cartridge surface of thetissue suturing side 2 is stepped, that is, the height of the outermost staple cartridge surface is lower than the height of the innermost staple cartridge surface, Specifically shown in Figure 2 and Figure 4. Such setting can make the molding shapes of the nails different, can make the sutured tissue get better hyperemia, and is conducive to the healing of the tissue.

本实用新型尚有多种具体的实施方式，等同替换或者等效变换而形成的所有技术方案，均落在本实用新型要求保护的范围之内。The utility model still has various specific implementation modes, and all technical solutions formed by equivalent replacement or equivalent transformation all fall within the protection scope of the utility model.
