A method and system for marking and guiding the insertion of securing members (e.g., pedicle screws) of a spinal fixation device. In one embodiment, the marking and guidance method and system includes the use of a guide tube configured to be inserted into a patient's back until a first end reaches an entry point on or near a vertebral bone of the patient's spinal column, wherein the guide tube includes a hollow cylindrical channel along its longitudinal center axis; a penetrating device configured to be positioned within the cylindrical channel of the guide tube and having a sharp tip configured to protrude outwardly from the first end of the guide tube so as to allow the first end of the guide tube to penetrate through the patient's back muscle and tissue and reach the vertebral bone at the entry point; a marking pin configured to be inserted through the cylindrical channel of the guide tube, after removal of the penetrating device, until a first end of the marking pin having a sharp tip reaches the entry point; and a pushing device configured to be inserted through the cylindrical channel of the guide tube and provide a driving force at a second end of the marking pin, opposite the first end, so as to drive and secure the first end of the marking pin into the vertebral bone, wherein the marking pin identifies the location of the entry point on the vertebral bone for subsequent implantation of a securing member of a spinal fixation device.

A flexible overlay for providing cooling therapy to the shoulder joint and the upper arm area. The overlay has pockets for holding cooling material; additional pockets can be attached to it in order to cool chest and/or back muscles or more of the upper arm area. One end of the overlay is removably secured around the neck, and the other end is wrapped around the wearer's upper arm. The overlay is typically made from a soft fabric such as cotton, but can also be made from a disposable plastic material.

A device that straps against the front of one's pelvis and features chest and leg engagements extending from a central main-body to create a personal upper body support system. As wearer bends forward from the waist, the leg engagements leverage oppositely threaded shafts to screw together into an internally threaded main-body either against a powerful spring means used to effect a compressive stop or a spring-back counter force to the wearer's overhanging upper body weight. A knob-ended threaded rod screws through one of the shafts to adjust the point of engagement and/or spring tension. This device creates a prop effect between the wearer's chest and upper legs. The oppositely threaded shafts provide a unique mechanism that divides the transferred load equally to each leg regardless of leg stance, as well as for allowing unrestricted upright walking.

An apparatus and a method for combiningly performing four important exercises localized to the lower back with the addition of weight resistance: a) the rotation or torsion of the lower spine and the lower back muscles; b) the bending of the spine forward and the exercising of abdominal muscles; c) the bending of the spine rearward and the exercising of the lumbar and erector muscles; d) the stretching and self-postural adjustment of the spine. The user performs the four exercises in the horizontal position with both legs in raised position. A swinging member accommodates the legs and allows the swinging, side-to-side motion of the legs. A second pivotal member helps the bending of the pelvis forward and rearward. A roller support assembly supports and massages the entire back during exercises. The user's body rests on an anatomical cushion support during exercises. The body's user experiences both the stretching of the intravertebral ligament and cartilage, while building postural awareness and self-adjusting spinal posture.

A low back exercise machine has a pivotally mounted user support frame carrying a user seat and a foot rest assembly, an exercise arm carrying a back pad pivotally mounted relative to the user support frame, and a connecting linkage which translates movement of the exercise arm into rotation of the user support frame about its pivot axis, whereby the user support including the foot rests moves from an upright into a rearwardly reclined orientation as the user pushes the back pad rearward and downward to lean backwards so as to exercise the lower back muscles.

The invention relates to a method for inducing gonad maturity and ovulation of a verasper variegates parent fish by implanting a slow-release hormone, which comprises two aspects of cultivating an optimally selected parent fish and adjusting temperature and light to promote the gonad development of the parent fish, and implanting the slow-release hormone for promoting a metrocyte of the parent fish to reach final maturity and ovulation. In the invention, the slow-release hormone is a salmon gonadotropin-releasing hormone analog (sGnRHa) and is coated with a safe and high-efficiency polymer slow-release transitive system (95 percent of cholesterol and 5 percent of cellulose); a female parent fish with gonad in fourth stage is selected by using a living body sampling method or a light table method; a special implanting gun is used for implanting in back muscles, and the effect time of the slow-release hormone lasts for 14-18 days. The method can enable the metrocyte of the verasper variegates parent fish to achieve final maturity and ovulation, has low duress on parent fish reproduction, high rate of parent fish survival and gonad maturity, high fertility rate being 72 percent and high hatching rate being 56.2 percent, and can acquire a bulk of high-quality oosperms. The invention is a set of complete control technique method, can stably regulate and control the development, the maturity and the ovulation of the gonad of the verasper variegates parent fish, and acquire high-quality oosperms.

The semi-sphere base prevents the floor from being scratched.

A leash that allows any individual to control a pulling dog without risking injury or walking in an unsafe manner. The disclosed leash maximizes body mechanics and basic pulley/lever principles to achieve more strength. The leash comprises a cuff that preferably wraps around a user's arm above the elbow. Attached to the cuff are a few feet of leash material that freely runs through an O-ring and ends in a handle. Attached to the O-ring are another few feet of leash ending with a clip that can go to a dog collar. When the dog pulls, the user pulls the handle. The resulting force goes through the O-ring, which acts as a pulley and on to the arm cuff and back of the arm, utilizing stronger shoulder and back muscles. Therefore the user is able to pull back with a lot more force than is obtainable with a typical leash.

Back cushion type spine healthcare and rehabilitation apparatus is formed by embedding a spine support structural part (2) connected with an elastic device (3) in a back cushion. Cervical spondylosis and lumbar spondylosis are common diseases in modern society, and one of the main causes is muscle strain. However, most products on the current market can only relax muscles, and the problem cannot be solved fundamentally, that is, the muscle function cannot be enhanced; through existing medical and exercise apparatus, training cannot be conveniently conducted anytime and anywhere, and the apparatus is not comfortable enough and hard to operate. According to the back cushion type spine healthcare and rehabilitation apparatus, the back cushion commonly used by people is combined with training apparatus; when a user is not in spine training, the apparatus can be used as a back cushion for the user to sit down; during training, the user presses the physiological curvature of the lumbar vertebra or cervical vertebra on the spine support to do reciprocating motion, the intervertebral disc structure can be relaxed in the direction of the physiological curvature, and meanwhile spine back muscles are subjected to function enhancement training. The back cushion type spine healthcare and rehabilitation apparatus has the advantages of being free of limitation of time and space, comfortable and easy to use.
