Abstract

The invention relates to the technical field of medical instruments, in particular to a medical operation sheath which comprises an air bag, a first metal strip, a second metal strip and a driving mechanism; the head and tail ends of the airbag are connected to form an annular balloon body; the annular balloon body is provided with an inward-rolling section located at the head end of the air bag and an inserting section located at the tail end of the air bag; a plurality of magnetic pieces are sequentially arranged in the middle of the inner side of the inward-rolling section at intervals. Oneend of the first metal strip is fixed to the middle of the internal face of the annular balloon body, the other end of the first metal strip is a free end which extends to the head end of the air bagalong the inward-rolling section, and the other end of the first metal strip is provided with a guide section which is used for being attracted to all the magnetic pieces; the second metal strip is fixed in the middle of the inner side of the inserting section; the driving mechanism is used for driving the second metal strip and the inserting section to be inserted into or extend out of the inward-rolling section. The medical operation sheath of the invention has a adjustable caliber, and the space of the operation channel will not be occupied when the caliber is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a medical operation sheath. Background technique [0002] Endoscopic operation is widely used clinically, and has the advantages of less damage and faster postoperative recovery. Before the operation, it is often necessary to establish a sufficiently large operation channel in advance with the help of the operation sheath, and then enter the body through the operation channel for operation. The diameter of the operating sheath is generally adjustable to reduce the pain and damage caused by intubation or extubation. [0003] Such as figure 1 As shown, an operating sheath is provided in the prior art, which includes a crimped tubular sheath body that passes through front and back, and an operation channel is formed inside the sheath body, and the sheath body includes an inner wall layer 2 and an outer wall layer 3 made of medical hard materials , the inner wall layer...
