A system of non-reactive components for moving or for moving and stretching plastic tissue that exerts a relatively constant dynamic force over a variety of distances and geometries, that is easily adjustable, and is self-adjusting. This system includes a “button anchor system” for moving tissue, particularly including deep fascia and muscle layers of the abdominal or thoracic cavity wall, in surgical, post surgical, and post traumatic reconstruction where the wound margins are beyond a distance that permits normal re-approximation. Button anchor assemblies allow re-approximation of severely retracted abdominal wall and full thickness thoracic wounds where a closure force is required to be applied to the sub-dermal layers. Systems of this invention allow for such a force to be applied and externally controlled during treatment.

A composition of a bone repair mixture has a quantity of allograft particulate bone having a bone particle distribution of particle sizes less than 700 micron and a quantity of biologic carrier material intermixed with the particulate bone. The biologic carrier material is one of fascia, deep fascia or a fascia mixture. Preferably, the carrier material is exclusively fascia lata.

The invention discloses surgical auxiliary equipment for closing a skin wound in superficial fascia of skin without a suture. The surgical auxiliary equipment comprises a subcutaneous negative pressure drainage device, a wound closing device and an epitrichial negative pressure device, wherein the subcutaneous negative pressure drainage device comprises a catheter which partially extends into an inner cavity of subcutaneous wound by a preset depth and is used for generating negative pressure to close the inner cavity of the subcutaneous wound in a healing process; the wound closing device is arranged on the peripheral side of the skin wound and is used for extruding the skin edge to keep the skin wound in a closed state in the healing process; and the epitrichial negative pressure device is arranged on the periphery of the skin wound and is used for generating negative pressure to maintain the stability of the tissue positions of the skin wound and the peripheral area of the skin wound. According to the surgical auxiliary equipment, suture-free closing of the whole-layer tissues above the deep fascia of the skin can be realized, transverse scars caused by suture compression / cuttingon the surface of the skin are avoided, and no suture knot is left in the superficial fascia, so that important factors causing bacterial colonization and main inducements of recurrence of incision infection are eliminated.

The invention discloses an operating channel system for a spinal minimally invasive microscope, comprising: an operating channel, the operating channel includes an outer tissue channel and an inner tissue channel, the inner tissue channel is fixedly connected with the outer tissue channel, the tissue The surface of the outer channel is vertically fixed with a fixed handle; the inner core includes a ball head, a ball handle and a connecting plate, and the ball handle is fixed vertically on the surface of the connecting plate, and the ball handle is far away from the connecting plate. One end of the disk is fixedly connected with the ball head; the dura mater pusher is used to cooperate with the operation channel to push away the dura mater tissue and nerve root for protection. This channel cuts the skin and deep fascia and directly places the channel for surgery, reducing the steps of gradually expanding the tissue and then placing the channel, reducing the operation time, and combined with the application of the dura mater pusher, it can be performed under a microscope in a limited space. operation without the risk of damage to the dura mater and nerve roots.

An electrode catheter is introduced into a vein or other hollow anatomical structure, and is positioned at a treatment: site within the structure. The end of the catheter is positioned near a junction formed in the structure. This junction can be the sapheno-femoral junction. The position of the catheter near the junction is determined based on a signal from a device associated with the catheter within the structure. A fiber optic filament which emits light is used with the catheter or a guide wire over which the catheter is advanced. The light is visible externally from the patient. The light dims and may no longer externally visible at the sapheno-femoral junction where the catheter moves past the deep fascia and toward the deep venous system. The position of the catheter can be determined based on this external observation. The position of the catheter can also be determined based on measured parameters such as temperature or flow rate within the structure, and the measured changes in one or more of these parameters as the catheter nears the junction. The hollow anatomical structure can be compressed for this procedure. The position of the catheter can also be determined mechanically by including a hook-shaped tip on the catheter or guide wire which would physically engage the junction.
