Low-damage and controllable biotic bone grinding process and device assisted by electrostatic-atomization ultrasonic waves

Abstract

The invention discloses an electrostatic atomization ultrasonic assisted low-damage controllable grinding process and device for biological bone, which solves the problem of serious blockage of bone debris in the prior art, and has the beneficial effects of good cooling effect and high operation efficiency. The scheme is as follows: an electrostatic atomization ultrasonic-assisted low-damage controllable grinding device for biological bone, including a main shaft, which can be rotated; a water-catching abrasive tool for grinding biological bone, the main shaft is connected to the water-catching abrasive tool through an ultrasonic vibration mechanism , driven by the main shaft and the ultrasonic vibration mechanism, the water-catching abrasive implements longitudinal and rotational movements; the cooling and film-forming mechanism is located on one side of the water-catching abrasive and is connected to the ultrasonic generator in the ultrasonic vibration mechanism, and the bottom is set to connect with the medical The nozzle connected to the nanometer liquid storage cup can also be fed with compressed gas to carry out pneumatic-ultrasonic atomization of the medical nanofluid, and rush into the grinding area in the form of droplets for effective cooling and lubrication; the endoscope is located at The other side of the water catcher.

Description

technical field [0001] The invention relates to a flexible integrated device for neurosurgical skull grinding, intraoperative cooling, and postoperative wound film formation, in particular to an electrostatic atomization ultrasonic-assisted low-damage controllable grinding process and device for biological bone. Background technique [0002] During skull base tumor removal surgery, taking pituitary tumors as an example, surgeons first use high-speed grinding tools to remove bone structures such as the nasal septum, the anterior bone of the sphenoid sinus, and the sella on the posterior side of the sphenoid sinus; Important nerves (eg, optic nerve, trigeminal nerve, carotid artery) are affected, so the surgeon also grinds away the bony structures surrounding these nerves to identify their location and protect them. Diamond abrasives are favored by neurosurgeons because of their small trauma to soft tissues, but the heat generated by diamond abrasives during the grinding proce...

AI Technical Summary

Problems solved by technology

[0013] After searching, the existing bone grinding devices did not consider the problem of bone chip discharge, and the grinding tool was seriously blocked; the hydrophilicity of the grinding tool was weak, and normal saline could not be effectively injected into the grinding area for cooling; the atomization of the coolant was not considered, and the cooling The particle size of the liquid droplets is large, which is not conducive to the spreading of the droplets
