Description

一种手术切口牵开器 A surgical incision retractor

技术领域 FIELD

[0001] 本发明专利涉及医疗器械领域,具体涉及一种手术切口牵开器。 Patent [0001] The present relates to medical devices, and in particular relates to a surgical incision retractor.

背景技术 Background technique

[0002] 外科医生在手术时需要充分利用切口观察、检查切口内的情况,然后通过切口实施手术。 [0002] When the surgeon takes full advantage of the surgical incision observation, inspection of the incision and the surgery through the incision. 在这个过程中,需要切口充分扩张,有利于手术操作。 In this process, the full expansion of the incision required, facilitate the surgical procedure. 一般来说外科医生都希望借助于一种器械扩大或牵开伤口。 General surgeons want to expand the device or by means of a wound retractor. 传统的切开牵开技术是用手术钳扩张切口,但是金属手术钳是刚性的而且体积大,占用空间多,不易固定,影响手术操作。 The traditional technique is to cut the retractor incision forceps expansion, but the metal forceps are rigid and bulky, space and more easily fixed, affects the operation.

[0003] 中国专利申请CN105380688A公开了一种软性筒状薄膜外翻牵开器。 [0003] Chinese patent application CN105380688A discloses a flexible tubular film valgus retractor. 它是一个柔性材料制成的筒状膜;在筒状膜上部开口处有一个柔性材料制成的双管上环;在筒状膜下部开口处有一个柔性材料制成的下环。 It is a cylindrical film made of a flexible material; ring has a double tube made of a flexible material in the opening portion of the cylindrical film; the lower ring made of a flexible material at the lower opening of the tubular film. 在使用时,先将下环和筒状膜用力塞入切口中,使下环置于体内,然后翻转上环的双管使之卷绕柔性筒状膜,这样柔性筒的高度就逐渐变小直至上环与切口皮肤接触,使柔性膜在切口内张紧。 In use, the first lower ring and the mouth of the tubular film Se Ruqie force, the lower ring in the body, and then flip the double tube so that the flexible ring wound tubular film, so that the height of the flexible tube gradually becomes smaller until the upper ring in contact with the skin incision, the flexible film is tensioned in the notch. 具有张力的柔性膜就可以迫使切口扩大到与柔性膜筒相近口径。 A flexible film having a tensile force can be expanded to close the incision and the cylinder diameter of the flexible film. 其主要缺陷在于筒状膜的横截面积(或周长)是固定的。 The main drawback is that the cross-sectional area of ​​the tubular film (or circumference) is fixed. 手术中切口大小要随着手术需要而确定,不仅仅只有几个固定的尺寸。 Surgical incision size needs to be determined with the operation, not just a few fixed size. 此外,其需要把一个很大尺寸的下环塞入体内,不利于手术,临床应用受到很大的限制。 Further, it requires a large size to the next ring inserted into the body, is not conducive to surgery, clinical application is greatly limited.

[0004] 还有很多类似的周长(或横截面积)固定的牵开器,区别仅在于将切口牵开的方式不同。 [0004] There are many similar circumference (or cross-sectional area) fixed retractor, differ only in the way the retractor incision. 例如,现有技术中的一些牵开器采用柔性带状环,使用时直接将环塞入切口,由于这个环是固定尺寸的,其柔性必须很好,否则很难塞入切口。 For example, some of the prior art retractor with flexible band-like rings, rings Se Ruqie port directly, because the ring is of a fixed size, which must be very flexible in use, it would be difficult Se Ruqie port. 然而,因为其柔性好,切口压力就会迫使该环变扁,无法达到切口扩大的目的。 However, because of its good flexibility, the pressure will force the ring slit becomes flat, can not achieve the purpose of the notch enlarged. 在现有技术中的一些牵开器中,为了防止牵开器在切口压力下变扁,有的牵开器用胶带将切口拉来并且固定在周边皮肤上,这种牵开器操作麻烦,并且也具有与CN105380688A公开的牵开器同样的局限性。 In the prior art some of the retractor to prevent the retractor pressure becomes flat at the incision, some incision retractor Used pull tape and fixed on the periphery of the skin, such a troublesome operation the retractor, and also it has the same limitations as CN105380688A disclosed retractor.

[0005] 中国专利申请CN105232097A公开了一种手术牵开器,它是由柔性金属环和若干个牵拉带组成,使用时需要将柔性金属环组装成环,塞入切口内腔,然后把牵拉带一端固定在金属环上,用力拉牵拉带,试使切口张开,然后将牵拉带固定在周边皮肤上。 [0005] Chinese patent application CN105232097A discloses a surgical retractor, which is of a flexible metal ring and a plurality of pull strap composition, the flexible metal ring will need to use a ring is assembled, Se Ruqie lumen port, and the pull drawstrings end fixed to the metal ring pull tape is pulled, so that the incision open again, and then pulling the tape is fixed to the periphery of the skin. 这个方法需要将一个金属环用力塞入切口内,手术完成后还需要再将这个环从切口内取出,同样操作不方便。 This process requires a metal ring firmly within the opening Se Ruqie, completion of surgery the need to loop again removed from the incision, the same operation is inconvenient. 而且,不同切口需要配备不同大小的金属环。 Furthermore, metal rings with different incisions require different sizes.

[0006]因此,亟需提供一种操作简便,能够适应不同大小手术切口的手术切口牵开器。 [0006] Accordingly, a need to provide a simple, can accommodate different sized surgical incision incision retractor. [0007]上述对背景技术的陈述仅是为了方便对本发明技术方案(使用的技术手段、解决的技术问题以及产生的技术效果等方面)的深入理解,而不应当被视为承认或以任何形式暗示该信息构成已为本领域技术人员所公知的现有技术。 [0007] the above statement of the background art is merely for the convenience of in-depth understanding of the technical solution of the present invention (technical means used to resolve technical issues and technical effects produced) and should not be taken as an acknowledgment or any form suggesting that this information forms known to those skilled in the prior art known.
