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.

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.
