The subtalar joint prosthesis comprises a talus assembly, a gasket and a calcaneus assembly, and the talus assembly and the calcaneus assembly are connected through the gasket to form a joint structure; by means of the split structure of the talus assembly, the gasket and the calcaneus assembly, all the assemblies are detachably clamped, step-by-step implantation and assembly in the operation process are facilitated, and therefore the adaptability of the prosthesis under different anatomical conditions is improved. The gasket is arranged between the talus assembly and the calcaneus assembly, a relative motion interface is formed between the talus assembly and the calcaneus assembly, the gasket is made of the low-friction material, direct friction between metal assemblies can be effectively reduced, abrasion is reduced, and the joint movement performance is improved. By means of the structural design, dependence of prosthesis implantation on accurate matching of bone surfaces is reduced, surgical operation is simplified, and meanwhile a feasible solution is provided for rebuilding after joint fusion operation.

The invention discloses a traditional Chinese medicine composition for treating osteoarthritis and application thereof. The ointment is prepared from the following raw materials in parts by weight: 30 parts of rheum officinale, 30 parts of golden cypress, 30 parts of scutellaria baicalensis, 30 parts of coptis chinensis, 30 parts of bletilla striata, 30 parts of ampelopsis japonica, 30 parts of radix angelicae, 30 parts of sophora flavescens, 15 parts of frankincense, 15 parts of myrrh and 100 parts of sesame oil. The traditional Chinese medicine composition can regulate qi and blood, dredge meridians and collaterals, promote blood circulation to remove blood stasis, clear heat and dry dampness, reduce swelling and promote tissue regeneration to relieve pain, is suitable for patients with qi stagnation and blood stasis syndrome type osteoarthritis caused by trauma or damp-heat, is especially suitable for patients who repeatedly attack for a long time and are difficult to radically cure, and has high clinical application value in the aspect of osteoarthritis treatment.

The present invention provides a variable stiffness fixation rod for spinal surgery, which belongs to the technical field of spinal surgical medical devices. It includes a first fixation rod connected to a second fixation rod, and a stiffness adjustment component and a supplementary component are installed on the second fixation rod. Before the stiffness adjustment component is dissolved, the supplementary component is pressed between the second fixation rod and the stiffness adjustment component, and the stiffness adjustment component increases the stiffness of the fixation rod; after the stiffness adjustment component is dissolved, the stiffness of the fixation rod is relatively reduced, and the stiffness adjustment component realizes stiffness adjustment. The supplementary component is pressed between the second fixation rod and the pedicle steel screw and the locking screw plug, offsetting the gap generated after the stiffness adjustment component is dissolved, and the supplementary component enables the pedicle steel screw and the locking screw plug to lock the second fixation rod; it is used to adjust the stiffness of the second fixation rod during use. It improves the joint mobility of the auxiliary fixation segment of the patient's spine, reduces the force of the internal fixation system, and reduces the risk of adjacent segment degeneration and internal fixation system failure.

The utility model relates to the field of medical instruments, and discloses a hand function training device which comprises an electroencephalogram cap and a muscle stimulator, the electroencephalogram cap is electrically connected with the muscle stimulator, the electroencephalogram cap is used for collecting electroencephalogram signals, and the muscle stimulator is used for receiving the electroencephalogram signals and sending out electrical stimulation signals based on the electroencephalogram signals. According to the hand function training device, training of the hand muscles and the central nervous system of the patient can be achieved, the hand muscles of the patient are trained through the hand function training device, the autonomous training consciousness of the patient can be stimulated, brain nerve repairing and remodeling of the patient are facilitated, and the rehabilitation effect of the patient is improved.
