Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present invention clearer and clearer, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032]The technical idea of ​​the present invention utilizes the material properties of existing rigid materials to realize orderly state changes of the overall rigid structure. One kind of material characteristic is the alloy memory characteristic, and some memory alloy materials have a two-way memory effect and can maintain two basic shapes with high and low temperature changes. Another material characteristic uses ...

Abstract

The invention provides a pediatric anorectal surgery medical instrument and an instrument expansion method, and solves the technical problem of deep discomfort in intraoperative and postoperative patients due to large damage to the anus in an existing instrument operation. The instrument comprises a bottom edge part, a supporting part and a top edge part which are sequentially arranged on the samevertical axis, the top edge part comprises an annular rigid part, the supporting part comprises a set of strip-shaped rigid parts which are parallel to the vertical axis and arranged in the circumferential direction, and flexible organic materials wrapping the surfaces of the strip-shaped rigid parts and the annular rigid parts are fused with one another; the annular rigid parts are made of memory alloy with a two-way memory effect and forms a small-diameter annular structure at low temperature and normal temperature and a large-diameter annular structure at high temperature, and the strip-shaped rigid parts are made of a bimetal layer material and are straightened at normal temperature to enable the supporting part to be kept vertical and bent at high temperature to enable the supportingpart to be kept dumbbell-shaped. A set of elastic air bags are arranged on the inner side of the supporting part to seal gaps between the strip-shaped rigid parts. The injury degree on the human bodyis effectively relieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a pediatric anorectal surgery medical instrument and an instrument expansion method. Background technique [0002] Open the anus during surgery for interventional procedures with an open diameter of 3 to 10 cm. In the prior art, anorectal surgery has made slow progress in intestinal surgery instruments for rectum to anus. Existing fixation devices fix the anal muscles by stretching, resulting in greater stress response and bleeding points, causing excessive damage to the soft tissue and internal and external sphincters when the anus is open, often causing tearing of the tissue at the fixed position of the external sphincter and damage to the soft tissue of the internal sphincter , making the postoperative recovery period very painful for patients. During postoperative recovery, due to the serious degree of anal injury, it is easy to form muscle adhesions. If it is n...
