As the first drive assembly rotates, the second drive assembly can continuously rotate together with the planet gear on the first drive assembly, thereby expanding the clinical application range of the adapter.

Adapter and surgical auxiliary system

The present disclosure discloses an instrument drive apparatus comprising an instrument assembly, a first rotating drive assembly, a second rotary drive assembly, and a push-pull drive assembly, the instrument assembly comprising a handle, operating levers slidably connected to the handle, and a rotary rod rotatably connected to the handle; a rotary seat mechanism is connected to the instrument assembly, a first rotary drive mechanism has an output end connected thereto for driving rotation of the instrument assembly; a rotary wheel mechanism is in transmission connection to the rotary rod, a second rotary drive mechanism has an output end connected thereto for driving rotation of the rotary rod; flexible push-pull wires and the operating levers correspond one to one, push-pull drive mechanisms drive reciprocation of the wires to cause the operating levers to reciprocate. The instrument drive apparatus reliably improves the control accuracy and motion stability of the end effectors.

Instrument drive apparatus

The present disclosure relates to the field of medical device technology, and specifically discloses a surgical execution apparatus and a surgical assistance device, the apparatus comprising a transmission cabin and a power cabin, the transmission cabin comprising a chassis assembly and first to third adapter transmission assemblies movable relative to the chassis assembly, the first to third adapter transmission assemblies comprising first to third transmission modules detachably connected to first to third adapter assemblies respectively; the power cabin being in transmission connection to the transmission cabin and configured to drive the first to third adapter assemblies via the first to third transmission modules. The apparatus enables more precise, stable and safe surgical execution operations through refined improvements in the transmission cabin.

Surgical execution apparatus and surgical assistance device

A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.

Systems and methods for suppressing sound leakage

The present disclosure relates to a bone conduction speaker and its compound vibration device. The compound vibration device comprises a vibration conductive plate and a vibration board, the vibration conductive plate is set to be the first torus, where at least two first rods inside it converge to its center; the vibration board is set as the second torus, where at least two second rods inside it converge to its center. The vibration conductive plate is fixed with the vibration board; the first torus is fixed on a magnetic system, and the second torus comprises a fixed voice coil, which is driven by the magnetic system. The bone conduction speaker in the present disclosure and its compound vibration device adopt the fixed vibration conductive plate and vibration board, making the technique simpler with a lower cost; because the two adjustable parts in the compound vibration device can adjust both low frequency and high frequency area, the frequency response obtained is flatter and the sound is broader.
