Abstract

The invention provides a medical traction guiding catheter with an adjusting structure and a using method thereof. The medical traction guide catheter comprises a left sheath tube and a right sheath tube, the left sheath tube comprises a left semicircular tube, a left expansion part and a supporting part, the left semicircular tube is provided with the left expansion part and the supporting part in an extending mode in sequence, and the right sheath tube comprises a right semicircular tube, a right expansion part and a holding part; a right expanding part and a holding part sequentially extend from the right half annular tube, the left sheath tube and the right sheath tube form a guiding catheter body, a safety channel is formed in the inner wall of the guiding catheter body, and an inner core used for protecting soft tissue is connected into the safety channel. The holding part is arranged over the supporting part, a fine adjustment driving mechanism used for enabling the bottom of the guiding catheter body to rotate and retract is arranged between the holding part and the supporting part, and a limiting notch used for limiting the retracting range of the bottom of the guiding catheter body is formed between the left expanding part and the right expanding part. The retraction range is convenient to adjust, the limiting effect is good, and the safety is high.

Description

technical field [0001] The invention relates to a medical retraction guiding catheter with an adjustment structure and a method for using the same, belonging to the technical field of retracting guiding catheters. Background technique [0002] The retractor guide catheter is suitable for blocking the soft tissue around the surgical field in clinical intracranial surgery. It belongs to neurosurgical medical devices and can be customized in various specifications. [0003] In the prior art, when the retraction guide catheter is used, it is sometimes necessary to expand the soft tissue. During the expansion, it is not convenient to adjust the retraction range, which affects the expansion effect, and does not have a limiting function, which is prone to over-positioning. , damage soft tissue, there is potential safety hazard, and the use effect is not good. Now there is an urgent need for a medical retraction guide catheter with an adjustable structure to solve the above-mentione...
