Presently provided are a method and a system for pulse electromagnetic field (PEMF) and decompression therapy. The system has a treatment table or treatment chair configured and disposed to hold a first body part of a patient. A decompression harness is configured and disposed to hold a second body part of the patient, wherein at least one joint of the patient is disposed between the first body part and the second body part. The decompression harness is configured to transfer a tensional force on the at least one joint of the patient and at least one PEMF treatment module is disposed with the decompression harness and proximate the at least one joint of the patient.

The application provides an artificial lamina for spinal decompression surgery, which comprises an arc-shaped lamina, both sides of the arc-shaped lamina are provided with C-shaped rotating grooves arranged along the length direction, the cross section of each C-shaped rotating groove is greater than one-half of a circle, both sides of the arc-shaped lamina are rotationally connected with arc-shaped wing plates matched with the arc shape, one side of each arc-shaped wing plate is provided with a rotating connecting shaft matched with the corresponding C-shaped rotating groove, and the free side of each arc-shaped wing plate is provided with a connecting plug strip arranged in the arc direction of the arc-shaped lamina, and each connecting plug strip is a porous mesh structure. The application uses the embedding method of the porous mesh structure to fuse and fix with the vertebrae, so that the bone-implant combination is mechanically stable and irreversible.

The utility model discloses a variable bone hook and depth limiting type spinal minimally invasive decompression operation robot belongs to medical instrument technical field. The robot passes through multiaxis mechanical arm drive guide connecting block, drives depth limiting equipment dynamic regulation cutting tool device and the working depth of detection device. Detection device adopts the variable bone hook structure of memory alloy bone hook subassembly or mechanical lever control, and cutting tool device retreats the knife, and through low temperature trigger mode switching or angle adjustment realizes safe separation, avoids secondary trauma. Cooperation elastic adjusting device real -time compensation vertebral plate outer surface safety height fluctuation, prevents the knife of cutting tool device and installs the knife and excessively invades the spinal canal. Control equipment coordinates multiaxis mechanical arm, guide motor and depth adjusting mechanism, realizes automatic positioning and dynamic limiting. The utility model has the functions of cutting tool safety feed, high accuracy positioning, self -adaptation depth compensation and safe knife withdrawal, can reduce minimally invasive spinal decompression operation risk.
