Description

Thrombus taking forceps for liver cancer portal vein cancer thrombus

Technical Field

The utility model belongs to the technical field of medical equipment, concretely relates to hepatoma portal vein cancer embolus forceps of getting.

Background

When liver tumor develops to middle and late stage, tumor embolus often invades main blood vessels of liver, such as portal vein and hepatic vein, and whether cancer embolus in the blood vessels can be completely removed directly influences the recurrence morning and evening of tumor and survival time of patients. At present, no special blood vessel cancer embolus taking forceps exist clinically, and most of used embolus taking instruments are replaced by the existing instruments such as biliary calculus taking forceps or tweezers. The forceps have a plurality of defects in the operation process: the pliers head is mostly circular arc structure, it is when taking the bolt in the blood vessel of intussuseption after opening, the circular arc head opens the size little, it is less to lead to once cancer bolt's the volume of snatching, still probably bulldozes cancer bolt toward blood vessel inside simultaneously, cause and get the bolt difficulty, and portal vein cancer bolt, the texture is relatively softer, most cancer bolt has more or less adhesion with portal vein blood vessel wall, there is little blood vessel to link to each other even, present blood vessel cancer bolt is got the bolt pincers and is mostly the fixed length, often appear the not long condition of tong arm inadequately in the in-service use, need be equipped with the blood vessel cancer bolt of different length and get the bolt pincers, therefore it is necessary to improve prior art, in order to.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a thrombus taking forceps for liver cancer portal vein cancer thrombus to solve the problem of the prior art.

In order to achieve the above object, the utility model provides a following technical scheme: liver cancer portal vein cancer embolisms and gets and tie pincers, including handle and tong arm, the fixed telescopic link that is provided with of one end of two sets of handles, one side that two sets of handle one ends are close to the telescopic link is fixed and is provided with spacing sawtooth, the fixed binding clip that is provided with in one end of two sets of tong arms, the through-hole has been seted up on two sets of binding clips, two sets of telescopic link pegs graft and is provided with the inside of two sets of tong arms, the installation blind hole has been seted up to two sets of telescopic link one ends are inside, the fixed spring that is provided with in inside of two sets of installation blind holes, the fixed location ball that is provided with in top of two sets of springs, the fixed two sets of stoppers that are provided with in bottom inner wall of two sets of installation blind.

Furthermore, the two groups of forceps heads are arranged into a circular arc structure, so that the cancer embolus can be conveniently grabbed.
