Neurosurgical ultrasonic focusing assisted three-stage atomization cooling and postoperative wound film forming device

Abstract

The invention discloses a neurosurgical ultrasonic focusing-assisted three-stage atomization cooling and postoperative wound film forming device, which solves the problem that the skull base tumor removal device in the prior art cannot cool the grinding area and timely coat the wound It has the beneficial effect of timely coating. The scheme is as follows: a device for neurosurgical ultrasonic focusing-assisted three-stage atomization cooling and postoperative wound film formation, a transducer shell, and a variable amplitude set inside the transducer shell At least two layers of piezoelectric ceramic sheets II are arranged on the top of the horn II, and an electrode sheet connected to the ultrasonic generator is arranged between two adjacent layers of piezoelectric ceramic sheets II. The bottom of the transducer shell has a hemispherical structure. The inner side of the spherical structure is provided with a plurality of piezoelectric elements connected to the ultrasonic generator; the nozzle is located at the bottom of the horn II, the nozzle is connected to the medical nanofluid storage cup, and compressed gas can also be passed into the nozzle, and the nozzle Electrodes are also provided inside.

Description

technical field [0001] The invention relates to a neurosurgery skull grinding, intraoperative cooling, and postoperative wound film forming flexible integrated device, in particular to a neurosurgery ultrasonic focusing assisted three-stage atomization cooling and postoperative wound film forming device. Background technique [0002] Bone grinding is one of the common and basic operations in skull base tumor removal surgery. In clinic, surgeons often use high-speed micro-grinding wheels to remove bone pathology. However, high-speed grinding produces a large amount of heat, which leads to osteonecrosis and thermal damage to surrounding tissues, and also has a certain impact on the coagulation function of tissues. Physiological saline drip cooling is commonly used in clinical practice, and part of the grinding heat is taken away by natural convection. Grinding thermal damage is a clinically recognized concern because the temperature cannot be determined during grinding to con...

[0023] After searching, the current electrospinning devices are characterized by bulky size, which is not conducive to the flexible and convenient use of surgeons in narrow spaces, and all of them only use the electric field force of the droplets to overcome the surface tension to make the droplets form jets, and the formed fibers are relatively thick. There is no spinning device or method that enables the operator to form ultra-fine fibers while operating flexibly, and there is no device that can realize ultra-fine atomization of cooling liquid and effectively inject it into the grinding area for cooling, and realize ultra-fine fibers.
