The invention relates to a single-channel minimally invasive arthroscope sheath which comprises a sheath body, and an observation cavity and an operation cavity are formed in the sheath body in the length direction of the sheath body. A spacer is arranged between the observation cavity and the operation cavity, and the axis of the observation cavity and the operation cavity form a cooperative working area in front of the imbedding end. According to the endoscopic sheath, a single-channel and double-function minimally invasive surgery mode is fundamentally realized. Through the physical isolation of the spacer and the space angle design of the observation cavity and the operation cavity, it is ensured that the arthroscope and the surgical instrument are parallel and do not interfere with each other in a single channel. In the operation process, the arthroscope can obtain a stable and clear operation field, a surgical instrument can directly reach an operation area in the preset direction, the arthroscope and the surgical instrument converge in a target area to form effective cooperation, and therefore a single incision is used for replacing traditional double channels, the wound area is reduced, and on the premise that operation operability is guaranteed, operation efficiency is improved. The number of channels is further reduced, and a more minimally invasive arthroscope sheath structure is achieved.

The risks of tissue damage, bleeding and infection are reduced. Meanwhile, the multi-channel positioning precision and collaboration are improved, the screw layout is optimized, the internal fixation stability is enhanced, the perspective frequency and X-ray exposure in the operation are reduced, and the operation safety and efficiency are improved. The invention is suitable for percutaneous minimally invasive fixation of complex pelvic fracture, and breaks through the application limitation of traditional rigid instruments.

A novel mechanical system, based on a new cable driven mechanical transmission, able to provide sufficient dexterity, stiffness, speed, precision and payload capacity to actuate multi-DOF micro-manipulators. Besides the possibility of being used in several articulated surgical instruments and robotic systems for surgery or other applications involving remote manipulation, it enables the design of a novel fully mechanical surgical instrument, which offer the advantages of: conventional laparoscopy (low cost, tactile feedback, high payload capacity) combined with the advantages of single port surgery (single incision, starless surgery, navigation through several quadrants of the abdominal cavity) and robotic surgery (greater degrees of freedom, short learning curve, high stiffness, high precision, increased intuition). The unique design of the proposed system provides an intuitive user interface to achieve such enhanced manoeuvrability, allowing each Joint of a teleoperated slave system to be driven by controlling the position of a mechanically connected master unit.

The invention provides a telescopic chest malformation orthosis and a use method. The orthosis comprises an arc-shaped orthosis body and a fixing assembly connected with the arc-shaped orthosis body in a sliding mode. The first end of the orthopedic body is provided with a fixing piece, and a runway-shaped hole structure and a side wall groove are arranged in a thinned area of the head of the second end of the orthopedic body. The transverse sliding assembly of the fixing assembly slides in cooperation with the groove through the protrusion, and the sliding position can be locked through the limiting assembly on the transverse sliding assembly. The length of the orthosis is adjusted through the sliding mechanism, and the growth and development requirements of children are met. The use method comprises the following steps: marking thoracic key points before an operation; fitting and shaping the orthopedic body; implanting through a single incision; penetrating through a sternum posterior gap under the guidance of a thoracoscope; turning the orthopedic main body to lift the sternum; and finally fixing two ends of the orthosis. According to the invention, the beneficial effects of minimally invasive implantation, precise orthopedic and dynamic adaptation are realized.

A surgical knife for introduction through a cannula includes a handle portion with an angled transition to a reduced portion. A blade connected to the reduced portion has a width perpendicular to the longitudinal axis that is equal to or greater than-half the effective handle dimension. The blade is connected to the handle so that the outer transverse edge of the blade is outwardly offset from the outer surface of the handle. The blade width is preferably 80% of the effective dimension of the handle. The blade includes a cutting edge that extends across the width of the blade. In use, the knife can be extended through a cannula to make a first incision, retracted and rotated 180°, and then make another incision colinear with the first incision to create a single incision having a length greater than the width of the cannula.
