Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:

[0029] See first figure 1 , figure 1 It is a structural representation of the present invention. like figure 1As shown, a curved balloon catheter retractor of the present invention is composed of the following parts: one end has a handle 2 with a diversion tube and a valve 1, a locator 3 and a pulling bag 4 arranged outside the catheter 5, the catheter 5 There are one or more cavities inside, and at least one hole is provided in the catheter 5 part in the positioner 3, and at least one cavity is controlled by the guide tube and the valve 1. 3 and the pulling bag 4 are filled with fluid, the fluid here is usually liquid and gas, and the pulling bag 4 will bend to one side when it is filled with fluid. In one embodiment, gas is injected into the gas inlet by a syringe. Closing the guide tube and the valve 1 after injecting the gas can make the pu...

Abstract

The invention provides a curved sac catheter retracting device. The device is characterized by comprising a catheter of which one end is provided with a handle, a positioning device and a retracting sac, one or more cavities are formed in the catheter, the catheter part is provided with at least one hole, fluid filling and releasing is conducted on the retracting sac by at least one cavity throughthe hole, when the retracting sac is filled with fluid, the retracting sac is bent towards one side, the handle can drive the catheter and the retracting sac to rotate, and therefore simple and reliable retracting can be achieved.

Description

technical field [0001] The invention relates to a catheter retractor, in particular to a curved balloon catheter retractor and a retraction method thereof. Background technique [0002] Retractors, also known as retractors, are used to retract tissues to reveal the area to be operated for easy exploration and operation. They can be divided into two types: hand-held retractors and automatic retractors. There are various specifications of different shapes and sizes, and the appropriate retractor can be selected according to the operation needs. [0003] Traditional retractors require a larger operating space, which requires a larger surgical wound. At the same time, traditional retractors are mostly made of metal and have sharp ends, which are likely to cause secondary trauma to the patient and damage important organs and tissues. [0004] At present, the retractable tissue retractor is widely used gradually, and it can pass through the working cavity of the retractable endo...
