Guiding catheter

Abstract

The invention discloses a guiding catheter. The guiding catheter comprises a handle and a catheter body which can be installed integrally, a handle inner cavity is formed inside the handle, and a handle connecting structure is formed at one end of the handle; a catheter inner cavity is formed inside the catheter, one end of the catheter is a puncturing end for puncture, the other end is an installing end, and two cavity openings are formed on a cavity wall between the puncturing end and the installing end. The guiding catheter has the advantages that a detachable structure is adopted, operability of the handle during the puncture is considered, effects of the size and the structure of the handle on guide during the guide are skillfully eliminated, difficulty of operations are greatly reduced, two-way guide is achieved, particularly for patients who have high thoraxes or obvious spine non-physiological curvatures and who need the two-way guide, probability of damage of shunts caused byrepeated guide during an operation is reduced, operational damage to the patients caused by increase of operational incisions due to the repeated guide is reduced, and operational time is shortened.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a guiding catheter used in neurosurgical hydrocephalus operation treatment. Background technique [0002] Hydrocephalus is one of the common diseases in neurosurgery. Now, the general treatment method for this disease is to use ventriculoperitoneal shunt surgery. In this operation, the guide catheter is an important instrument. The currently used guide catheter is one-piece, and its end for holding usually forms a thick cylindrical handle, which cannot pass through the subcutaneous tunnel. The piercing end is formed into a sharp piercing shape, which has the ability to pierce the skin. The problem encountered with the existing guide catheter is that, due to the existence of the handle, the guide catheter is only suitable for guiding along the direction of puncture during the operation, and the guidance in the reverse direction of puncture requires additional operations and tools. That is...

Problems solved by technology

The problem encountered with the existing guide catheter is that, due to the existence of the handle, the guide catheter is only suitable for guiding along the direction of puncture during the operation, and the guidance in the reverse direction of puncture requires additional operations and tools. That is to say, the existence of the handle prevents the section of the guide catheter forming the handle from entering the subcutaneous tunnel, so that the end of the handle cannot be used as a catheter nozzle equivalent to the puncture end

At present, there is no guiding catheter that can effectively achieve two-way guidance on the market.
