The application discloses a traditional Chinese medicine micro-invasive regulating needle therapy method and belongs to the technical field of traditional Chinese medicine micro-invasive treatment, and solves the technical problems that traditional therapy for treating soft tissue pain only focuses on the local part and is difficult to solve the adhesion of deep and shallow fascia layers and has a high recurrence rate. The method takes a needle-knife as a main treatment tool, integrates a needle-knife medical theory, a fascia chain theory, a traditional Chinese medicine meridian theory and a biomechanics principle, adheres to a local relaxation + overall regulation core idea, accurately positions a treatment target through three points and one side, intervenes in inflammation-adhesion-spasm three pathological changes, follows a chain point finding and pain treatment by relaxation rule, and finally realizes a treatment goal of human body muscle and bone neutralization. The application is suitable for neck, lumbar vertebra disease, joint pain and related soft tissue lesions of head, face, spine and six big joints and has the advantages of micro-invasiveness, precision, treatment of both symptoms and root causes and low recurrence rate, and effectively restores the symmetry stability and functional coordination of the mechanical structure of the human body.

The present invention discloses a modular mechanical free-clutch exoskeleton joint. The modular mechanical free-clutch exoskeleton joint includes a first connecting ring, a second connecting ring, a bionic joint, and a driving member. The bionic joint includes a mounting seat, a rotating ring, and an eccentric block. The mounting seat is connected to the second connecting ring, the rotating ring is connected to the first connecting ring, and the rotating ring has a mounting groove. The eccentric block is rotatably connected in the mounting groove. The mounting groove has a contact driving surface that can abut against the eccentric block. The driving member is installed on the mounting seat. The driving shaft of the driving member is in transmission cooperation with the eccentric block to drive the eccentric block to rotate. During the rotation of the eccentric block, the rotating ring can be driven to rotate to drive the first connecting ring to rotate relative to the second connecting ring. This modular mechanical free-clutch exoskeleton joint can achieve energy-free switching between assisted movement and free movement of any large joint of the human limbs, improving the safety, comfort, coupling degree, flexibility, and endurance of the exoskeleton joint.

FIELD: medicine.SUBSTANCE: invention relates to medicine, namely to neurology, traumatology, and orthopedics. It can be used in the treatment of pain syndrome in patients with osteoarthritis of large joints. The method involves conducting 5-10 xenon therapy procedures using the Carboxica device. The drug is injected subcutaneously, para-articularly around the joint at a distance of 2-3 cm from each other, with an interval of 48 hours. The xenon dosage per procedure is 5 ml / kg of the patient's weight.EFFECT: method is available, increases the effectiveness of treating pain syndrome in patients, and has a long-term analgesic effect.1 cl, 3 tbl, 3 ex

This invention provides a joint cavity expansion device for shoulder arthroscopic surgery, comprising a main tube, an injection balloon, supporting blades, an injection line, a drainage line, and a sealing structure. In use, the main tube is first inserted into the established channel in the shoulder joint. Water is injected into the injection line through a one-way valve using a syringe. The liquid enters the injection balloon through the injection channel, causing it to expand and deploy the supporting blades to support the bottom of the balloon. The main tube is then screwed outwards, fixing its position via spiral protrusions on the tube wall. Simultaneously, the injection balloon compresses the surrounding soft tissue, effectively increasing the operating space within the joint cavity. This joint cavity expansion device significantly expands the operating space within the joint cavity by compressing soft tissue with the injection balloon, ensuring flexible operation of surgical instruments without restricting the surgical field of view. The supporting blades provide stable support when the balloon expands, preventing deformation during soft tissue compression, thus achieving stable compression of the soft tissue.

This invention provides a hydraulically driven artificial muscle robotic arm module and a modular robotic arm. The robotic arm module includes joint links, a root muscle connector, a hydraulically driven artificial muscle, joint connectors, end muscle connectors, and tension springs. The joint links include four links. The joint connectors include a joint shaft, which is mounted on the first link assembly and the second link assembly. The root muscle connector includes a first root connecting block, a second root connecting block, a root support block, a connecting shaft, a root muscle fastening stud, and a root muscle fastening nut. The end muscle connector includes a first end connecting block, a long connecting shaft, an end support block, a second end connecting block, an end muscle fastening stud, and a second end fastening nut. The technical solution of this invention has significant advantages such as high modularity, compact structure, simple control, large joint torque output, and flexible load bearing.

The invention discloses a posterior cervical spinal canal expansion titanium plate fixing system, and relates to the technical field of orthopedic implants. Aiming at the following three problems of an existing titanium plate, the titanium plate is improved and designed, so that the problem of axial pain after a posterior cervical approach in clinic can be effectively reduced: the existing posterior cervical approach titanium plate is lack of a posterior complex repairing and anchoring structure, so that the posterior cervical extensor muscle amount is insufficient, and the physiological curvature is lost; the side block end of an existing titanium plate is fixedly installed through two screws, the joint capsule stripping range is large, the penetration rate of the screws on the articular surface reaches 30%, and arthritis is caused. An existing titanium plate is too high in elasticity modulus, and activity stress is concentrated on the door shaft side, so that a door shaft is not healed. The device comprises a main body supporting plate, a vertebral plate end fixing plate, a lateral mass end fixing plate, a rear complex anchoring titanium wire, a lateral mass end extending double-clamping groove and a fixing buckle. The vertebral plate end fixing plate and the lateral mass end fixing plate are arranged in parallel, the vertebral plate end fixing plate and the lateral mass end fixing plate are connected through the obliquely-arranged main body supporting plate, and the vertebral plate supporting device is used for supporting the vertebral plate after the cervical spondyloplasty.

Apparatus and methods for joint and bony segment replacement may utilize additive manufacturing (e.g., 3D printing) of various anatomic constructs with PEEK / zeolite / ion (PZI) material. Heavy metal ion loading options may be utilized which may provide differing properties to different surfaces of the resultant apparatus. Moreover, using the PZI material, the apparatus being implanted in joint and bony segment replacement may favorably manipulate the biologic microenvironment in which it may be implanted. Further, through use of PZI material, current large joint replacement options also may be disrupted including, but not limited to, modifications of the joint replacement itself, and the augments and supporting joint reconstruction devices used in bone loss situations. Methods for joint and bony segment replacement may provide mixing two or more types of PZI material together through an additive manufacturing process; and introducing the mixture as part of an implantable apparatus.
