Description

负压式皮肤外扩张器 An outer negative pressure tissue expander

技术领域 FIELD

[0001]本发明涉及一种皮肤扩张器,具体涉及一种负压式皮肤外扩张器。 [0001] The present invention relates to a skin dilator, an outer one kind particularly relates to a negative pressure tissue expander.

背景技术 Background technique

[0002]组织扩张术是利用组织扩张器的扩张作用获得额外皮肤软组织进行皮肤缺损修复和器官再造的一种外科方法。 [0002] Tissue expansion is the use of tissue expanders to expand the role of additional skin and soft tissue defects and organ reconstruction is a surgical method of skin. 组织扩张术是近20年来整形外科领域的一项革命性成果,在瘢痕、体表肿物等治疗中用最为广泛,解决了临床上许多疑难问题,取代了一些皮肤移植术和皮瓣移植术。 Tissue expansion is nearly 20 years, the field of plastic surgery a revolutionary achievement, with the scar, the most widely used body mass and other treatment, to solve many difficult problems in clinical, replacing some skin grafting and skin flap . 皮肤扩张术的应用不仅提高了整形外科的治疗质量,而且减轻了手术损伤。 Skin expansion of applications not only improve the quality of orthopedic treatment, and reduce the surgical injury.

[0003]扩张可增加皮肤面积,这一部分额外获得的皮肤软组织有三个来源:①扩张刺激诱导的组织生长,皮肤的生长在扩张过程中和扩张皮瓣转移后都存在。 [0003] increase the expansion area of ​​skin, skin and soft tissue of this part receive an additional three sources: ① Irritation induced tissue growth, skin growth during expansion and after the expansion flaps are present. 扩张中的细胞增殖和细胞间质物质的合成有助于皮肤面积的扩展;扩张皮瓣转移后又有助于皮肤厚度的恢复。 Between cell proliferation and cell expansion contributes to the synthesis of substance in the extended area of ​​skin; flap after expansion helps to restore the skin thickness. ②蠕变效应,此效应是生物性组织在力的作用下面积发生扩展或长度增加,而力的作用解除后生物性组织的面积或长度不能完全复原的特性。 ② creep effect, this effect is a biological tissue extended under the force of the occurrence or increase the length of the area, and after releasing the force of the area or length of tissue of the biological characteristic can not be completely restored. 而不能复原的那一部分面积或长度即是组织的面积或长度增加量。 And that a portion of the area or length is not restored, i.e., increasing the amount of area or length of tissue. 由组织蠕变效应产生的皮肤面积增长是扩张区皮肤面积增长总量中的一部分,但最终要在扩张组织移植后被组织细胞的真正生长所取代。 Area of ​​skin tissue growth resulting from the effects of creep is a fraction of the total area of ​​skin growth in the expansion region, but ultimately replaced by the real growth of tissue cells after expansion in tissue transplantation. ③皮肤软组织移位,是机体皮肤受力向力源方向移动的特性,它构成扩张区皮肤的外围部分,也是扩张区面积增长的一个组成部分。 ③ skin and soft tissue displaced by the characteristics of the skin is the body force source of direction of movement, which constitutes the peripheral portion of the expansion region of the skin, but also a part of the expansion area growth. 这部分皮肤软组织的获取在皮瓣转移时要部分回复到原来部位,另一部分最终也要在扩张组织移植后被组织细胞的真正生长所取代。 Get this part of the skin and soft tissue to be partially recovered in the flap to its original position, but also in another part of the final expansion of the real growth of tissue after tissue transplanted cells replaced.

[0004]经典的扩张术是内扩张,其基本步骤包括:扩张区和扩张器的选择、扩张器埋置术、术中注水扩张和术后定期注水扩张等。 [0004] The classic dilatation within an expansion which substantially comprises the step of: expansion region selection dilator dilator buried intraoperative and postoperative periodic water injection expandable dilation. 由于涉及技术步骤多,治疗周期长,很容易出现问题。 As it involves a multi-step technique, the treatment cycle is long, it is prone to problems. 血肿、感染、扩张器外露和扩张后皮瓣血运障碍是皮肤软组织扩张术最常见的并发症,发生率约在10%左右。 Hematoma, infection, dilator exposed and expanded flap blood circulation disorder is the most common complication of skin and soft tissue expansion, the occurrence rate of about 10%. 由于扩张器的置入通常需要住院治疗,注水也需要一个长期的过程,导致费用相对较高。 Since the placement of the dilator usually require hospitalization, water also needs a long-term process, resulting in relatively high cost. 另外,由于进行注水需要针头进行治疗,对于一些儿童患者具有非常大的恐惧心理。 In addition, as a result of injection needles need treatment for some patients with very large children's fears.

[0005]皮肤外扩张器主要是针对以上的缺点设计的,主要通过所制装备,在皮肤外持续牵引皮肤绀织,随着牵引重量的增加和的推移,使得病变(如:瘢痕)周围的皮肤逐渐延伸,提供“额外”的皮肤组织供修复之用。 [0005] The outer skin dilator is mainly designed for the above shortcomings, mainly produced by the equipment, the outer skin of the skin cyanosis woven continuous traction, traction with increasing weight and goes such lesions (such as: scar) around skin gradually extended to provide "extra" skin tissue for repair purposes. 传统皮肤外扩张装置由外扩张器及牵引架组成。 Traditional skin outer expandable stent device and traction by the outer frame assembly. 扩张器由牵引夹头、牵引臂及其调节结构共同组成。 Expandable collet by the traction, the traction arm and the adjustment structure composed. 外扩张器能够实现在家庭中自行操作,“产生”新生的皮肤,为组织缺损的修复提供可能。 Outside dilator can achieve on their own operations in the family, "produce" new skin, may provide for the repair of tissue defects. 相对于内扩张,减少了埋置扩张器的一次住院治疗,减轻了就医难的医疗难题。 Relative to the inner expansion, reducing the once buried dilator of hospitalization, medical alleviate the difficult medical problem. 目前外扩张器可以分为两类:一类是使用简单的晾衣夹子这样简陋的日常用品;另外一类就是价格比较昂贵的专门器械,操作相对复杂,成本随着增加。 Currently outer dilator can be divided into two categories: one is the use of simple clamps laundry such simple everyday; is another type of specialized instruments are expensive, complicated operation, with the increase of the cost.
