Description
Technical Field
The utility model belongs to the technical field of medical science appurtenance, concretely relates to supplementary lithotomy forceps of choledochoscope.
Background
With the development of social production, the medical level is greatly improved, the medical environment is also improved, the development of medical instruments is convenient for doctors to work, and simultaneously the pain of patients is relieved, particularly surgical instruments, wherein biliary tract lithotomy forceps are an indispensable part of the biliary tract lithotomy forceps.
Bile duct calculi are common frequently-occurring diseases, the prior solution is mainly used for surgical treatment, the problems can be better solved by using a stone removing forceps or a choledochoscope to remove stones in general operations, but part of stones are large, the stones are embedded and difficult to remove and clean, and serious consequences caused by cholangitis, pancreatitis, liver function damage and the like can occur after the operations.
At present, two methods for removing the stone from the biliary tract in the operation have major defects: the biliary tract lithotomy forceps are invisible, the choledocholithiasis forceps are difficult to take out and clean the choledocholithiasis forceps by blind operation, and complications such as biliary tract injury, biliary-intestinal perforation, pancreatitis and the like exist; although the choledochoscope has the advantage of direct vision operation, the stone-taking basket is soft and the size of the basket is limited, so that large stones and stones embedded in the biliary tract are difficult to take out.
Therefore, a novel choledochoscope auxiliary lithotomy forceps is urgently needed, the problems are solved, the work of doctors is facilitated, and the pain of patients is relieved.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an instrument has cholangioscope and gets the stone pincers function simultaneously to solve the problem that proposes in the above-mentioned background art.
For realizing the purpose of the utility model, the technical proposal adopted is that: a choledochoscope auxiliary lithotomy forceps comprises finger ring sleeves, forceps handles, a rotating shaft, forceps arm I, a clamping part and a hollow pipeline, wherein the two finger ring sleeves are respectively connected with the two forceps handles, and the two forceps handles are respectively connected with the two forceps arm I through the rotating shaft. The top ends of the two first clamp arms are respectively provided with a clamping part, tooth marks are arranged on the clamping parts, the hollow pipeline is fixed on one of the two pairs of clamp handles and the first clamp arms, and the tail end of the hollow pipeline is close to and fixed at the rear end clamping part of the first clamp arm.
Preferably, the finger ring sleeve, the forceps handle, the rotating shaft and the forceps arm I are made of medical 304 stainless steel.
Preferably, the hollow pipe has a diameter of 7 mm.
Compared with the prior art, the beneficial effects of the utility model are that: the defects that the stone-taking net basket is soft and small when the choledochoscope takes stones can be avoided; the defects of blind fetching and multiple complications of a common lithotomy forceps can be avoided, and the lithotomy forceps have the advantages of high hardness and large opening of a choledochoscope visual forceps, and can achieve the characteristic of effectively and quickly fetching calculus.
