本发明涉及一种切口保护器，更具体的说是涉及一种适应小切口的切口保护器。The present invention relates to an incision protector, more specifically relates to an incision protector adapted to small incisions.
背景技术Background technique
在外科剖腹手术中，当医生切开患者手术部位后，因为组织收缩作用，切口会呈闭合状态。过去，医生会在患者皮肤切开后利用金属牵拉器或者拉钩将切口拉开，从而达到暴露手术视野的目的，但经常发生牵拉过度至撕裂伤口或暴露角度不够的情况。目前已经研发出各种切口保护器应用于临床，通常为外环、置入环及两者之间的套筒状薄膜。现阶段，将切口保护器的置入环伸入至切口内，外环停留在体外，从而达到使切口张开的目的，医生可以在套筒状薄膜形成的手术通道中，对患者施以手术。然而，现有的切口保护器的置入环大小固定，置入环的口径大小不能进行调节，在一些小切口的手术中，需要按压置入环，使置入环形变收缩后再放入切口中，若操作不当，容易牵拉切口，使得切口开口面积增大，增加了患者伤口愈合的时间；同时，在小切口手术结束时，由于置入环难以变形，导致置入环取出困难。In a surgical laparotomy, when the doctor cuts open the patient's surgical site, the incision is closed due to tissue contraction. In the past, doctors used metal retractors or hooks to open the incision after incision of the patient's skin, so as to expose the surgical field of view. However, excessive retraction often caused tearing of the wound or insufficient exposure angle. At present, various incision protectors have been developed for clinical application, usually an outer ring, an insertion ring and a sleeve-shaped film between the two. At this stage, the inserting ring of the incision protector is inserted into the incision, and the outer ring stays outside the body, so as to achieve the purpose of opening the incision. The doctor can perform surgery on the patient in the surgical channel formed by the sleeve-shaped film. . However, the size of the insertion ring of the existing incision protector is fixed, and the diameter of the insertion ring cannot be adjusted. In some operations with small incisions, it is necessary to press the insertion ring so that the insertion ring shrinks and then put into the incision In the case of improper operation, it is easy to pull the incision, which increases the opening area of the incision and increases the wound healing time of the patient. At the same time, at the end of the small incision operation, it is difficult to remove the inserted ring because it is difficult to deform.
