Abstract: Disclosed is an ultrasonic hemostasis and cutting system, comprising an ultrasonic vibration propagation assembly. An ultrasonic scalpel bit (101) of the ultrasonic vibration propagation assembly comprises an ultrasonic scalpel tip (11), a connection portion (13), vibration node bosses (14) and a waveguide (15), wherein the ultrasonic scalpel tip (11) is arranged in front of the waveguide (15), the connection portion (13) is arranged behind the waveguide (15), the vibration node bosses (14) are arranged on the waveguide (15), the ultrasonic scalpel tip (11) is laterally bent at a pointed end thereof, and a vibration guide groove (12) is further provided on the ultrasonic scalpel bit (101). By designing the ultrasonic scalpel bit in a bent shape and converting a longitudinal ultrasonic vibration into a longitudinal torsional composite vibration, temperature uniformity inside a tissue being cut or coagulated can be improved, thereby improving the efficiency and safety of hemostasis and cutting.

Abstract: A minimally invasive ultrasonic cutter head and a minimally invasive ultrasonic powered system for bone; the minimally invasive ultrasonic cutter head comprises an cutter rod (11, 21, 31, 41, 51, 61) and a head end (12, 22, 32, 42, 52, 62), the head end (12, 22, 32, 42, 52, 62) being located at a front end of the cutter rod (11, 21, 31, 41, 51, 61), and the head end (12, 22, 32, 42, 52, 62) being bent laterally at a certain angle, wherein knurled teeth or skewed teeth are provided on the bent portion. By means of bending the head end (12, 22, 32, 42, 52, 62), bone tissue around the intervertebral foramen may be removed. Therefore, a surgeon may, as much as possible, have more operation space under the limited foramen channel, thereby increasing bone removal efficiency.

Abstract: A discrete bioelectrical impedance identification device, comprising a control module (1) and a detection module (2), wherein the control module (1) comprises a control shell (20) and a control processing circuit (21) provided inside the control shell (20); the control shell (20) is provided with conducting strips (201) which are partially exposed out of the control shell (20); the conducting strips (201) are electrically connected to the control processing circuit (21), wherein the detection module (2) comprises a detection shell (23), a probe (231) embedded in one end of the detection shell (23), a power supply (232) embedded in the other end of the detection shell (23), and a conducting needle group (233) partially exposed out of the shell; the control shell (20) is detachably connected to the detection shell (23); when the control shell (20) is firmly connected to the detection shell (23), the conducting needle group (233) abuts against the conducting strips (201); and when the control shell (20) is separ
