Repeating titanium clamp pincers

Abstract

The invention discloses repeating titanium clamp pincers, which comprise a pincer body and a nail storage for filling a titanium clamp. When in use, the clip storage is inserted into the pincer body, and a handle is pinched to realize the clamp-closure of the titanium clamp and is released to finish the automatic filling of the next titanium clamp. The repeating titanium clamp pincers can effectively improve the operative speed, shorten the length of operation and reduce the probability of falling off of the titanium clamp when apparatuses are passed; in addition, only the titanium clamp and the nail storage are disposable apparatuses, while the pincer body can be sterilized and repeatedly used, thus the cost on use of the repeating titanium clamp pincers is low and economical burdens of patients can be relieved; besides, bended pincer heads can provide wider field of view and internal-mounted structural parts are beneficially for being prevented from contaminating by the operation.

Description

technical field [0001] The invention relates to a surgical instrument for ligating blood vessels, in particular to a continuous-fire titanium clamp. Background technique [0002] During surgery, shock and even death due to bleeding are one of the main risks of surgery. Traditional surgical methods use ligation, suture or compression of blood vessels to achieve the effect of hemostasis. In recent years, titanium clip hemostasis is a new type of hemostasis method, and its speed is greatly improved compared with traditional methods. The speed of operation is directly related to the amount of surgical bleeding. On the other hand, the hemostasis of titanium clip is more reliable, and the tissue compatibility is good, and the inflammatory reaction is smaller than that of silk thread. In laparoscopic surgery, because the characteristics of the operation itself limit hemostasis by silk ligation, titanium clip hemostasis has become the main means of ligation of large and medium-size...

AI Technical Summary

Problems solved by technology

At present, there are single-shot titanium clamps commonly used in China, that is, during the operation, the instrument nurse completes the filling of each titanium clip, and then passes it to the operator. Every time a titanium clip is used, the operator and the instrument nurse need to pass it twice. The operation time is prolonged, and the phenomenon of prolonging the operation time is more obvious in laparoscopic surgery; in addition, the burst titanium clamp produced by Johnson & Johnson Medical Equipment Co., Ltd. It avoids the waste of operation time due to the transfer of the device, but the device is a disposable device, which is expensive and greatly increases the financial burden on the patient

[0003] my country's patent application 200710037750.6 discloses a semi-automatic continuous firing titanium clamp, which has a continuous firing function and can be reused, but it has the following problems: first, the clamp head is composed of a titanium clamp upper body and a titanium clamp lower body. When closing, only the upper body of the titanium pliers moves, while the lower body of the titanium pliers is always in a fixed state. The upper body of the titanium pliers has a large movement stroke, which is not conducive to the closure of the titanium pliers. In addition, the pliers head is a straight pliers head, which is easy to block the view; secondly, The arrangement of the titanium clips in the titanium clip box is arranged in series, which makes the ejection of the titanium clips from the titanium clip box relatively complicated; again, the filling of the titanium clips with the titanium clips is semi-automatic, and additional actions are required to push the titanium clips, which is relatively complicated. Inconvenient; finally, the structural parts in the pliers are exposed, and are easily affected by blood and impurities after repeated use. Once the cleaning is not complete, its performance will be affected
