Description

Inflatable positioning and guiding device for neuroendoscopy operation

Technical Field

The utility model relates to a neural scope operation location field particularly, relates to a neural scope operation location guiding device of inflatable.

Background

As an advanced minimally invasive technique, neuroendoscopy has been applied to surgical treatment of cerebral hemorrhage, and operation of the operation requires an endoscope introducer to establish an operation channel, so that an endoscope and related instruments can be applied to remove hematoma. However, an endoscope guide which is convenient, practical, simple to operate and low in cost is still lacking clinically at present, and the endoscope guide mainly has two forms, namely a syringe type, and the similar injector is inserted into a hematoma position, then a piston is pulled out, and hematoma is removed in a channel. This device has the following disadvantages or shortcomings: 1. when the puncture needle is placed in the blind insertion state, the puncture depth and the puncture process cannot be observed, and brain tissues are easily damaged; 2. when the piston is pulled out, certain negative pressure can be generated, so that brain tissue damage is caused; 3. the piston needle core is not fixed and is easy to move, the piston needle core protrudes out of the sleeve if the piston needle core is too long, and the piston needle core retreats into the sleeve if the piston needle core is too short, so that brain tissue injury can be caused under the two conditions. The other is duckbill type, the device is duckbilled, is inserted into brain tissue in a closed state, and is expanded to open the duckbill after reaching the hematoma part, and the hematoma is exposed and removed. This device has the following disadvantages: 1. the duckbill structure is non-circular, and brain tissue is easily damaged during puncture; 2. after reaching the hematoma position, when the duck bill is expanded, the edges at the two sides of the duck bill can damage brain tissues; 3. the operation channel formed by the duckbill structure is not a closed annular channel, but is open at two sides, so that the brain tissue hernia enters the channel in the hematoma removing process to cause brain tissue injury; 4. the device also has the disadvantage of blind insertion. Due to the lack of corresponding instruments, clinicians can also make various simple channels to remove hematoma, and most of the simple channels are simple and crude and have limited application value.

To solve this problem, there is therefore a need for an inflatable neuroendoscopic surgical positioning guide to solve this problem.
