Catheter catcher with snake bone

Abstract

The invention discloses a catheter catcher with a snake bone, which is characterized by comprising a catheter, a coating tube arranged on the catheter, a hydrophilic coating arranged on the coating tube, a handle arranged on the catheter, a forceps head assembly arranged on the catheter and used for grabbing foreign matter in a blood vessel, wherein one end of the catheter is connected with the handle, and the other end of the catheter is connected with the forceps head assembly, and snake bones arranged at the tail end of the catheter, wherein the number of the snake bones is multiple, the multiple snake bones are sequentially arranged end to end, and the snake bones are further connected with the forceps head assembly. In the operation process, the catheter is arranged through the multiple snake bones, the forceps head assembly is connected with the snake bones, and then the forceps head assembly can be guided to reach the preset position by controlling the bending direction and bending degree of the snake bones, so that a doctor can capture foreign matter in a blood vessel or take out calculi in a zigzag biliary tract.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a catheter catcher with snake bones. Background technique [0002] In surgery, intravascular capture is a very commonly used treatment method in the medical field. This treatment method is relatively mature, but the current equipment for capturing intravascular devices is relatively inflexible and difficult to meet the needs of surgery. Due to the low bending ability and low operability of the currently used grabbers, it is more difficult for doctors to operate the catheter grabber when dealing with complex blood vessels in the human body; At the same time, there is also an urgent need for a flexible catheter catcher. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an adjustable catheter catcher that can be bent in multiple directions. [0004] In order to achieve the above object, the present inventio...
