Abstract: A flexible endoscope system is provided for use in surgical operation which includes a head part and a control handle detachably connected using first and second docking keys. The head part comprises a shaft, a flexible tip located at a distal end of the shaft, an image sensor module, and drive tendons extending in the shaft for controlling the movement of the flexible tip in multiple degrees of freedom. The control handle includes multiple motors for tensioning or relaxing the drive tendons via a capstan assembly. Control element is provided on the control handle to allow a user to trigger a complex movement of the flexible tip to form an S shape so that a bird-eye view of the surgical site can be obtained by the endoscope system. The detachable connection eliminates the need to sterilize the control handle in which the main electronic components are located.

Abstract: The present disclosure relates to a surgical robotic arm, a flexible arm, and a flexible joint. The flexible joint (1) comprises two support sections (11) and an articulated section (12) connected between the two support sections (11), the articulated section (12) including a plurality of first turns (121) with contact aided parts (122); wherein, the contact aided parts (122) are oppositely arranged on two sides of each first turn (121), and when the flexible joint (1) is in a bent state, the contact aided parts (122) of adjacent first turns (121) are in contact with each other; and wherein at each first turn (121) of the articulated section (12) are provided a plurality of tendon through-holes (5) for a driving tendon (6) to pass through. Compared with the prior art, the flexible joint of the present disclosure has the merit of less misalignment proneness and better reliability.

Abstract: A method and system for analysing gait patterns of a subject by measuring head acceleration in vertical direction. The system comprises an accelerometer mounted on the head of the subject. The analysis includes calculating a signature from the acceleration data, using a Fourier transform, including energy of the first harmonics and comparing the signature with the baseline signature. Baseline signature is a representative of previously stored signatures. The comparison is done in order to monitor changes in the gait signatures over time. The entropy of the signatures may be used to perform the comparison. A self organised map is used to classify the measured gait signals.

Abstract: A humanised antibody capable of binding to the MUC1 mucin antigen comprises a light chain and a heavy chain. The variable region of the light chain (VL) comprising an amino acid sequence which is substantially homologous with the sequence of FIG. 1A and the variable region of the heavy chain (VH) comprising an amino acid sequence which is substantially homologous with the sequence of FIG. 1B. The amino acid residue at position 46 on VL is backmutated to arginine, and the amino acid residue at position 47 on VH is backmutated to leucine. The humanised antibody has use in the diagnosis and/or treatment of cancer.
