Description

Multidirectional ultrasonic scalpel system

Technical Field

The invention relates to the field of medical instruments, in particular to a multidirectional ultrasonic scalpel system.

Background

The ultrasonic scalpel utilizes a high-intensity focused ultrasound technology, converts electric energy into vibration mechanical energy through an energy converter, and vaporizes water in tissue cells in contact through high-frequency ultrasonic oscillation to break protein hydrogen bonds, so that bone tissues needing to be cut in an operation are thoroughly damaged. Because the high-intensity focused ultrasonic waves only have a destructive effect on bone tissues with specific hardness, blood vessels and nerve tissues cannot be damaged, the high-intensity focused ultrasonic waves also have a hemostatic effect on an operation wound, the wound of a minimally invasive operation is further reduced, and the accuracy, reliability and safety of the operation are greatly improved.

Through the mass search of the team, the known existing ultrasonic scalpel mainly has the publication numbers of JP2014533132A, KR101331155B1 and CN101790358B, wherein the structure of the ultrasonic scalpel disclosed by the publication number of CN104173093B is particularly representative, and the ultrasonic scalpel head is integrated with a torsion limiting device and has the characteristic of being not easy to lose. The torque limiting device comprises a rotating device and a force transmission device, wherein a force application surface of the rotating device is pressed and tightly attached to a force bearing surface of the force transmission device through a pushing mechanism, and the force application surface and the force bearing surface can be helical teeth which are arranged along the circumferential direction and are meshed with each other. The torque is transmitted through the acting force between the force applying surface and the force receiving surface, and the friction force depends on the pressure of the pushing mechanism, so that the set torque can be transmitted by reasonably setting the pushing force, and when the torque is larger than the set value, the meshed helical teeth can overcome the pushing force and the friction force of the pushing mechanism to slip, so that the transmission of the torque is limited, and the protection effect is achieved. The operator only needs rotary device, just can lock external drive handle, dismantle operations such as drive handle and rotatory tool bit angle, easy operation is convenient, the stability and the convenience of this kind of structure to the tool bit have a promotion, but the tool bit angle and the sword orientation of the ultrasonic knife of this kind of structure have all been fixed, and because the fixed user that has also restricted the angle of control handle carries out the rotation adjustment angle to the scalpel, and current general in order to promote the control of scalpel, the mode of generally commonly holding is operated, this kind of gesture often is sheltered from the sight by the scalpel when medical personnel stand patient's side-of-body operation.
