Surgical tools with fully conformable multifunctional artificial fingers for neuroendoscopy

Abstract

The invention discloses a surgical tool used for neuroendoscopy and provided with conformal pleuripotent simulation fingers. The surgical tool comprises a gun barrel and a compressed balloon, a ventilating pipe is arranged in the gun barrel, the front end of the ventilating pipe extends outside the gun barrel and provided with the hollow simulation fingers, the front end of the ventilating pipe is communicated with the simulation fingers, and the rear end of the ventilating pipe is communicated with the compressed balloon; the bottom of the end, close to the compassed balloon, of the gun barrel is provided with a gun supporting handle, a trigger and a spring piece, the trigger is hinged to the gun barrel, the top of the trigger is arranged in the gun barrel, one end of the spring piece is connected to the gun supporting handle, and the other end of the spring piece is connected to the trigger; a pressure ring is arranged outside the compressed balloon, the end of the pressure ring extends inwards the gun barrel and arranged in the gun barrel; the surgical tool further comprises a linkage device, one end of the linkage device is connected with the end of the pressure ring, and the other end of the linage device is connected with the top of the trigger. The surgical tool has the advantages that a gun type structure is adopted, the compressed balloon is squeezed to fill and press a surgical cavity, bleeding of a coloboma bone window is handled, and bleeding is controlled.

Description

technical field [0001] The invention relates to a surgical tool in the medical field, in particular to a surgical tool with fully conformable and multi-functional artificial fingers for neuroendoscopy. Background technique [0002] With the development of neurosurgery equipment and technology, a large number of skull base operations have been carried out, and the wide application of neuroendoscopy has brought neurosurgery into a comprehensive minimally invasive field. Because the surgical site is deep and the operating space is narrow, the instruments used under neuroendoscopy are a necessary means to use both hands to extend, and it is also the biggest technical bottleneck encountered in current skull base neurosurgery. Especially with the development of neuroendoscopic technology, the scope of application of transnasal endoscopic surgery into the cranium has been greatly expanded. Through the double nostrils, the bones of various parts of the entire skull base can be opene...

Problems solved by technology

[0003] At present, the clinical method for hemostasis of skull wounds under endoscopy is mainly to use electrocoagulation for cauterization. However, due to the complexity of the bone surface and the limitation of the field of view of the instrument, it is basically impossible to reach the bleeding position, so we can only rely on increasing the power of electrocoagulation. Carry out continuous cautery to achieve the purpose of hemostasis, but this also causes a large area of ​​burns to the surrounding structures, especially neurovascular damage is often irreversible; another method is to seal with bone wax or sealant, but this needs to be given Bone wax or glue applies pressure to smear it into the bone suture, but due to the limitation of the operating space, we can only fill the cotton piece to achieve this purpose. Since the direction of the cotton piece can not be accurately judged, the operation is time-consuming and laborious, and the effect is not good. good
