Hand-held neurosurgical rotary ultrasonic resonance water-harvesting grinding device

Abstract

The invention discloses a hand-held neurosurgical rotary ultrasonic resonance water-harvesting grinding device. The problems that a skull base tumor removal device in the prior art is large in size and difficult to operate are solved. The device has the advantages of high grinding efficiency and good cooling effect. According to the technical scheme, the hand-held neurosurgical rotary ultrasonic resonance water-harvesting device includes a main shaft and a water-harvesting grinding tool for grinding biological bones. The main shaft is disposed in an electric spindle housing, a rotor winding iscircumferentially arranged on the outer surface of the main shaft, a stator winding corresponding to the rotor winding is disposed in the electric spindle housing, and the electronic windings can beenergized to drive the rotation of the main shaft. The main shaft is connected to the water-harvesting grinding tool through an ultrasonic vibration mechanism, and driven by the main shaft and the ultrasonic vibration mechanism, the water-harvesting grinding tool realizes longitudinal vibration and rotary motion, and micro-convex bodies are arranged on the surface of the water-harvesting grindingtool.

Description

technical field [0001] The invention relates to a neurosurgical flexible integrated device for skull grinding, intraoperative cooling, and postoperative wound film formation, in particular to a handheld neurosurgery rotary ultrasonic resonance water-catching grinding device. 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 process is significantly higher than that o...

Problems solved by technology

[0015] In order to prevent thermal damage to peripheral nerve tissue, Toshiyuki Enomoto (T. Enomoto, H. Shigeta, T. Sugihara, U. Satake, A new surgical grinding wheel for suppressing grinding heat generation in bone resection, CIRP Ann-Manuf Techn.63 (1 )(2014) 305–308 et al. invented a new type of diamond spherical abrasive tool and verified its ability to reduce the temperature in the grinding zone by experiments. 2 , however, it cannot effectively capture the cooling liquid water film, and still cannot solve the problem of excessive bone grinding temperature

[0016] After searching, the current rotating ultrasonic longitudinal and torsional resonance devices all need to be installed on the spindle of the machine tool, which has the characteristics of bulky, complex structure, and inconvenient operation. There is no device or method that enables the surgeon to perform the operation of skull base tumor removal. It is convenient and flexible to operate, and there is no grinding tool that can effectively capture coolant during bone grinding
