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

Abstract

The invention discloses a hand-held neurosurgical rotary ultrasonic resonance water-catching grinding device, which solves the problems of large volume and difficult operation of the skull base tumor removal device in the prior art, and has the advantages of high grinding efficiency and good cooling effect Effect, the scheme is as follows: a hand-held neurosurgical rotary ultrasonic resonance water-catching grinding device, including a main shaft, which is arranged in the electric spindle shell, a rotor winding is arranged on the outer circumference of the main shaft, and a stator winding corresponding to the rotor winding is arranged in the electric spindle shell , the electronic winding can be energized to drive the spindle to rotate and set; the water-catching abrasive for grinding biological bones, the spindle is connected to the water-catching abrasive through an ultrasonic vibration mechanism, driven by the spindle and the ultrasonic vibration mechanism, the water-catching abrasive realizes longitudinal vibration and rotating motion, asperities are arranged on the surface of the water catching abrasive.

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
