Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] figure 1 , 2 Among them, an invasive reverse titanium clip, including a reverse titanium clip, the shape of the reverse titanium clip is M-shaped, wherein the V-shaped part in the middle of the reverse titanium clip is the release section 1, and the two sides of the reverse titanium clip Part of it is a clamping segment 3 , the two ends 3 of the clamping segment 3 are bent inwards, and the two ends 3 are provided with at least one engaging saw tooth 4 .

[0029] According to the specific requirements of use, various reverse titanium clips of different sizes can be customized. Generally speaking, for the gastrointestinal NOTES treatment technique, the diameter of the overtube 6 is required to be 3.7-4.2mm, the length of the clamping section 2 of the reverse titanium clip is 2-3mm, the length of the release section 1 is 1-2mm, and the release sec...

Abstract

The invention relates to intrusion type inverted titanium clips. The intrusion type inverted titanium clips comprise inverted titanium clips, wherein the inverted titanium clips are M-shaped; the middle V-shaped part of the inverted titanium clips is a release section, the two sides of the inverted titanium clips are clamping sections; two ends of the clamping sections are bended inward; and the each end is provided with at least one sawtooth for meshing. The invention also discloses a use method of the inverted titanium clips. The intrusion type inverted titanium clips can realize multilevel, multiple-degree-of-freedom and free release, effectively close the outer wall of an orifice puncture hole and solve the problems of the bleeding and fistula of the puncture hole after the operation so as to avoid abdominal infection, septicemia and the like caused by gastric fistula, intestinal fistula and the like. When closed, the inverted titanium clips of the invention are shaped like a reverse triangle and can basically intrude orifice issue, and the outside of the orifice is smooth, thus the damage of the visceral organ outside the orifice can be prevented. The intrusion type inverted titanium clips are convenient, fast and reliable to use, has good clamping performance, is characterized by good clamping property and toughness and no displacement after clamping, and overcomes the current bottleneck that the outer wall of the orifice can not be closed.

Description

[0001] technical field [0002] The invention relates to a medical and sanitary appliance and its use method, in particular to an invasive reverse titanium clip and its use method. Background technique [0003] Surgical scars, in the history of more than 100 years of surgical development, are considered to be the inevitable product of surgery, and in order to obtain sufficient exposure of the surgical field, major surgery must use a larger surgical incision, so there is a saying "big doctor, big incision" statement. Until the 1980s, the rise of laparoscopic minimally invasive surgical techniques made people gradually realize that small incisions through the abdominal wall can also perform routine abdominal operations, and has the advantages of fast postoperative recovery, less pain for patients, and good cosmetic effects. With the popularization of minimally invasive technology and the concept of minimally invasive surgery, people have gradually changed their understanding ...
