Anti-fall and anti-damage wire

Abstract

The invention relates to the field of medical apparatuses, in particular to an anti-fall and anti-damage wire. The anti-fall and anti-damage wire is characterized by comprising a thin-long-pipe-shapedbody internally provided with an inflating cavity and an airbag arranged at the front part of the body and communicated with the inflating cavity. The head of the anti-shed and anti-damage wire can be clamped inside the organ and is prevented from falling out of the target organ or entering the organ or other surrounding viscera and blood vessels by too large depth, and thus the occurrence of a severe complication is prevented.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an anti-falling and anti-injury guide wire. Background technique [0002] Visceral fistula surgery is a relatively common operation in clinical practice, such as pyelostomy, cystostomy, hydrocephalus fistula, gastrostomy and so on. It is to connect the organ cavity or infection focus directly to the outside of the body by establishing a new channel, so that drainage, flushing, or various diagnostic and therapeutic operations can be performed through this channel. The guide wire in ostomy is a very important link, which plays a role in guiding various instruments. [0003] For example, pyelostomy is an important operation in urology. Its purpose is to drain the renal pelvis and improve renal function, so as to reduce the infection of the renal pelvis and renal parenchyma. It can also be used to remove kidney stones by establishing this channel. , and various operations such as res...

[0004] However, the problem of the prior art occurs in the process of guiding the rest of the instruments into the renal pelvis after the guide wire is inserted in place. The guide wire must be slender and smooth; however, such a structure makes it easy to slip out of the renal pelvis during the process of guiding other instruments, and because the guide wire is so thin, such slippage is very difficult to detect, once the guide wire is not returned to the renal pelvis in time , then the drainage tube will fail to be inserted into the renal pelvis, and the tube placement will fail, which will seriously affect the progress and success rate of the operation; It is easy to find the original insertion channel. In most cases, it is necessary to create a new channel to insert the renal pelvis. If the guide wire is reinserted too many times during the operation, it will seriously affect the operation time, and it will also cause damage to the relevant tissues of the patient. secondary injury

In addition, in the process of dilating through the guide wire, because the front end of the guide wire is not blocked or limited, the dilator can easily lead the guide wire to the wrong position due to the angle deviation from the puncture channel, including entering too deeply outside the renal pelvis or even Peripheral organs and vessels, or into the renal parenchyma

At the same time, the force of the dilator during the expansion process will cause the displacement of the kidney, including distant displacement and rotation, which will easily lead to the prolapse of the guide wire or the change of direction, resulting in the failure of channel establishment
