The second direction, in which the inclined part 3 extends, is inclined at an angle of α in a range of 95° or more and 115° or less to the first direction, in which the shaft 2 extends, and the inclined part 3 includes on the outer edge thereof a notch 10 through which a screw is passed.

The application discloses a shoulder lock joint dislocation minimally invasive reduction threading kit in the technical field of fracture threading reduction, which comprises a hooking wire clamp, a ring rotating hook rod, a threading clamp and a clavicle clamp. The hooking wire clamp is in a scissor-shaped structure capable of being opened and closed and is formed by connecting two straight rods through a rotating shaft. The two straight rods of the hooking wire clamp are both provided with holding handles at rear ends. The front end of one straight rod of the hooking wire clamp is rotatably connected with the ring rotating hook rod. The front end of the other straight rod of the hooking wire clamp is provided with the threading clamp. After the coracoid process of the scapula and the clavicle are positioned, the threading clamp can be used to stably penetrate along a rotating path into the bone to be positioned, so that the bone to be reduced can be precisely and quickly threaded. Because the holding is convenient and the stress is stable, the muscle and ligament are not easily disturbed, so that the device can conveniently and stably position the bone to be positioned and thread and wind.

The utility model discloses a hook-shaped fixing steel plate for ulna coracoid process fracture. The device comprises a main plate, a protruding attaching part and a hook part which are integrally arranged and are integrally in a hook shape. The hook part is matched with the upper surface of the ulna coracoid process in shape, and the outer edge of the hook part is in a blade shape; the protuberance fitting part is matched with the anatomical form of the coronal process lateral column, and the main plate is matched with the anatomical form of the lower end part of the coronal process lateral column; a plurality of screw holes are formed in the protruding attaching part and the main plate. The fixing effect on small fracture blocks is optimized, the postoperative effect is guaranteed, and the living quality of a patient is improved.

Shoulder tape (1) is affixed to the upper body of a user (H) in a range including a shoulder, and the shoulder tape (1) comprises a base section (2), front tape (3), rear tape (4) and an anchor section (5). The base section (2) is attached to the upper body so as to cover the humeral head from the front. The front tape (3) is connected to the base section (2) and extends towards the coracoid process. The rear tape (4) is connected to the base section (2) and extends along the acromial process toward the spina scapulae. The anchor section (5) is connected to the base section (2) and is wrapped around the upper arm via the underarm.

The utility model discloses a percutaneous positioning bidirectional adjustment coracoid-clavicle bone tunnel guider which comprises a base, a scale guide rod, a positioning guide needle, a sliding locking knob assembly, a height-adjustable guide rod assembly and an angle-adjustable guide sleeve assembly. The scale guide rod is fixedly connected to the upper portion of the base, the positioning guide pin sleeve is arranged on one side of the base, the positioning guide pin penetrates through the positioning guide pin sleeve and is fixed through the first limiting nut on the side wall of the positioning guide pin sleeve, and the sliding locking knob assembly is fixedly connected with one end of the height-adjustable guide rod assembly. The sliding locking knob assembly and the height-adjustable guide rod assembly are both arranged on the scale guide rod in a sleeving mode and can slide up and down, and the angle-adjustable guide sleeve assembly is movably connected to one side of the height-adjustable guide rod assembly. The coracoid bone tunnel drilling device is used for positioning and drilling the clavicle to the coracoid bone tunnel when the loop steel plate technology is used for treating acromioclavicular joint dislocation, coracoid side non-incision minimally invasive positioning can be achieved, trauma is small, bone tunnel positioning is more accurate, operation is convenient, and the clinical application effect is good.

A user may attach a navigational tracker to a clamping tool. The clamping tool may include a foot configured to receive a screw. For example, the foot may include a hole configured to receive the screw. The user may attach the clamping tool to a coracoid process. The user may insert a screw into the coracoid process, for example through the foot of the clamping tool. The user may remove at least a portion of the clamping tool from the coracoid process. The navigational tracker may be attached to the foot of the clamping tool. The foot of the clamping tool may remain attached to the coracoid process, for example during a surgical procedure. The navigational tracker may include at least one electromagnetic sensor.

A shoulder implant for simulating a naturally occurring bursa proximal to or in lieu of a subacromial bursa, the shoulder implant comprising: an expandable member expandable to a size and / or a shape sufficient to fill a space beneath an acromion and / or a coracoid process of the shoulder, the space defines a filled volume less than a maximal volume occupied by the expandable member if fully expanded; and an amount of filler for filling the expandable member to the filled volume, such that, when implanted, the expandable member is configured to cushion and facilitate motion between a tendon and / or ligament of a rotator cuff, and a bone part in the shoulder.

The invention discloses an ulna coracoid process internal fixing device with a good pressurizing effect, and relates to the technical field of medical equipment.The ulna coracoid process internal fixing device comprises a bone fracture plate body, the bone fracture plate body is matched with the front structure of ulna coracoid process, the bone fracture plate body comprises a spiral steel plate integrally formed on the side wall of the bone fracture plate body, and fixing holes are linearly distributed in the bone fracture plate body; the device further comprises a supporting plate, reinforcing parts are circumferentially arranged on the outer side of the supporting plate, the reinforcing parts are arranged on the outer sides of the fixing holes, a sleeve is arranged at the bottom end of the supporting plate, an adjusting mechanism is arranged in the sleeve, gaps are counteracted through a self-adaptive mechanism, and tighter pressurization is achieved. Postoperative inevitable harmful micro-motion is converted into irreversible incremental pressurization capacity, so that a fixing system can actively obtain energy from a dynamic healing environment, and better bone healing force is continuously maintained.
