Omnibearing mechanical arm with simulation palm, applied to neuro-endoscope

Abstract

The invention discloses an omnibearing mechanical arm with a simulation palm, applied to a neuro-endoscope. The mechanical arm comprises a fixation base which can be fixed on an operation bed, a universal hose and an adjustment device capable of 360 DEG position adjustment, wherein the adjustment device is composed of a universal bass base and an universal ball; one end of the universal hose is fixed on the fixation base and the other end is connected to the bottom face of the universal ball base; one end of the universal ball is placed in the universal ball base, and the other end is connected to the simulation palm; the simulation palm comprises multiple fingers which are set to be bent into an arc shape; and clamping holes are formed in the fingers. The mechanical arm also comprises the neuro-endoscope, wherein one end part of the neuro-endoscope is placed on the simulation palm; a positioning part is disposed on the end part of the neuro-endoscope; and the simulation palm clamps the end part of the neuro-endoscope in a wine glass holding shape; and the positioning part is clamped by the clamping holes. The mechanical arm disclosed by the invention has the advantages that fixation effects of the neuro-endoscope are good; damage appearing in adjustment of the neuro-endoscope can be effectively avoided; and position adjustment is more accurate, omnibearing adjustment can be achieved, two hands can be relieved, and doctors' operation burdens can be relieved.

Description

technical field [0001] The invention relates to surgical tools in the medical field, in particular to an omnidirectional mechanical arm with a simulated palm 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. Due to the deep surgical site and the narrow operating space, the instruments used under the neuroendoscope are a necessary means to extend the hands, and they are 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 has been greatly expanded, and the bones of the entire skull base can be opened almost through the double nostrils, which greatly reduces the trauma of patients.

Problems solved by technology

However, due to the narrow operating space, it is difficult for two people to operate. Since the angle of the endoscope needs to be adjusted continuously during the operation, the surgeon also needs to occupy one hand to fix the endoscope. Therefore, the operation is often performed by the surgeon with one hand, which greatly increases the difficulty of the operation. The scope of operation is severely limited, the operation time is significantly increased, and the operation safety is significantly reduced

[0003] The operating space for transnasal surgery is narrow, and the angle of the neuroendoscope needs to be constantly adjusted. The current robotic arm is composed of many joints, and each joint needs to be loosened and re-fixed every time it is adjusted. It cannot be applied to transnasal neuroendoscopic surgery at all. , so that one hand of the surgeon needs to be occupied to hold the mirror, causing the doctor to operate the surgical instrument with one hand, which cannot be performed at all in the complex and densely-packed skull base. Only two surgeons can coordinate the operation, which not only takes up human resources At the same time, the two surgeons still need to go through a long period of running-in to cooperate well.

[0004] At present, there are still no effective, easy-to-use, fixed and convenient surgical instruments that can be adjusted at any time, which increases the surgical operation, increases the risk of important structural damage, prolongs the operation time, and increases the probability of postoperative infection
