A method for implanting a medical lead. The method includes advancing a tunneling tool posteriorly proximate the caudal end of the sternum toward a first location. The tunneling tool is advanced superiorly underneath the sternum through the anterior mediastinum from the first location to a second location cranial to the first location. A guidewire is advanced from the first location to the second location. A medical lead is slid along at least a portion of the guidewire, the medical lead at least substantially spanning the distance between the first location and the second location.

An access platform having a first and a second blade interconnected to a spreader member that laterally drives the blades apart or together and a sternal pad interconnected to a blade. The superior blade is preferably pivotally coupled to the spreader member such that it naturally rises as the blades are separated. Alternatively, a vertical displacement member is operably interconnected to a blade and the spreader member and is used to vertically displace the interconnected superior blade and, thus, increase a surgeon's working space and visual access for the dissection of an internal mammary artery. A tissue retractor is interconnected to the blades to draw the soft tissue around an incision away from the surgeon's working area.

The invention relates to an individualized sternum prosthesis with computer-aided design and a manufacturing method. The method comprises the steps of collecting CT data of the chest of a patient, and establishing a three-dimensional chest model; measuring parameters of the sternum of the patient; utilizing modeling software to design the shape of manubrium of the prosthesis with the shape of biological manubrium as a reference; designing a plurality of hole channels at the connection edges of the clavicles and the ribs on the manubrium of the prosthesis; designing the size of the part, inserted in the cavity of the sternum, of the sternum prosthesis according to the size of the inner cavity of the sternum of the patient, wherein the sternum part of the prosthesis is vertically provided with hole channels, the diameter of the hole channels is 5-6 mm, the top end of the sternum of the patient needs to be excised 10-12 mm before the sternum prosthesis is placed into the cavity of the sternum, the placement position of the sternum prosthesis is completely identical to the position of the computer-aided design, and the upper end of the sternum of the prosthesis and the connection portions of the manubrium are additionally provided with ladder-like bulges. Through the adoption of the individualized sternum prosthesis with the computer-aided design, regarding the characteristics of an anatomical structure of the chest of an individual, the accurate data measurement of the sternum of the patient are achieved, the thoracic structure of the patient is perfectly matched, and the problem that the movement range of the upper limbs of the patient is limited is solved through ligament connection.

The invention discloses a sternum-clavicle integrated piece. The sternum-clavicle integrated piece comprises a sternum plate, a clavicle strip and a joint connecting the sternum plate and the claviclestrip. The sternum plate is in a sheet shape and comprises a layered object formed by twisted carbon fiber rope braid and carbon fiber nonwoven fabric through superposition and carbon matrix and/or silicon carbide arranged between carbon fibers in a filling mode; the clavicle strip is in a strip shape and comprises the twisted carbon fiber rope braid and carbon matrix and/or silicon carbide arranged between the carbon fibers in a filling mode, or comprises the layered object formed by the twisted carbon fiber rope braid and the carbon fiber nonwoven fabric through superposition and carbon matrix and/or silicon carbide arranged between the carbon fibers in a filling mode; and the joint is in a spring shape and comprises a spring body formed by weaving a twisted carbon fiber rope and the carbon matrix and/or silicon carbide arranged between the carbon fibers in a filling mode. The sternum-clavicle integrated piece has the characteristics of light weight, good biocompatibility, good chemical stability, mechanical properties close to human bones, good fatigue, high designability, no artifacts and the like, and is particularly suitable for reconstruction use.

The invention relates to a sternum expanding device with the sternal closure delaying function. The sternum expanding device is characterized by comprising a base part and a sternum groove upper part; the base part comprises an arch board part and sternum groove lower parts; the arch board part is arranged in the middle, and the sternum groove lower parts are symmetrically arranged at the two ends of the arch board part. The device is compact and ingenious in overall structural design, accurate in positioning, simple in operation, short in operation time and small in damage to sick children, expanders of many types are adopted, and the device is suitable for the sick children of different ages and different types and wide in application range.

Provided is an implant for sternum replacement including an upper face, a posterior face, extensions for fitting with the ribs and extensions for fitting with the manubrium, wherein that implant is manufactured in a single piece with high performance engineering polymers, with an anatomical adjustment tailored to each patient, which guarantees the reduction of the number of elements in contact with the patient, facilitating and speeding up the surgical procedure, at the same time, the required mechanical and flexibility properties, are guaranteed.

Implant positioning devices for use with and assisting in positioning orthopaedic fixation devices (such as bone plates, etc.). An implant positioning device may include a body that has a fastener guide with slits in a first end of the fastener guide that form a retaining arm proximal to the first end of the fastener guide. The implant positioning device may also be coupled to a bone plate by a retaining beam positioned within the implant positioning device to facilitate ease of alignment and insertion of the fastener into a fastener apertures of the bone plate.

The invention provides a method and system for judging sleep depth based on sternal manubrium anterior area brain waves. The method comprises the following steps of: collecting brain wave informationat the sternal manubrium anterior area of a testee by a physiological information picking-up transmitter; continuously reading the collected brain wave information within the collection period, wherein the brain wave information comprises at least one of alpha brain waves, beta brain waves and theta brain waves; judging whether the sleep depth of the testee by the brain wave information is in thestate of eye closing, or the somnolence state or the deep sleeping state; and separately counting the accumulative duration of the state of eye closing, the somnolence state and the deep sleeping state, using the accumulative duration as sleep parameter data, and outputting the accumulative duration, wherein the brain wave signals comprise the alpha brain waves, the beta brain waves and the thetabrain waves. The system adopts the method. The method for judging the sleep depth based on the brain waves is accurate for sleep depth judgment, the testee only needs to wear the physiological information picking-up transmitter, and the sleep state of the testee cannot be influenced.

Provided is a surgical saw for cutting a sternum comprising: a) a body, b) a handle attached to the body; c) a blade positioned in such way to cut the sternum when a user holds the handle, and d) a base below the blade configured to be positioned below the sternum, wherein the user places the base under the sternum and cuts the sternum with the blade.
