The utility model belongs to the technical field of medical apparatus and instruments and provides a radial artery intervention operation compression hemostat, including support plate, bandage, compression hemostat mechanism, radial bone clamping plate and ulna clamping plate, radial bone clamping plate top end rotation connection is in support plate left end, and ulna clamping plate top end sliding is established in support plate right -hand side, and the bottom surface of support plate right -hand side is provided with the vertical board, and the vertical board is provided with the screw rod in screw connection, and radial bone clamping plate bottom end and ulna clamping plate bottom end all are set up strip -shaped bushing, and the right end of bandage is fixed in ulna clamping plate bottom end, and its left end bottom surface is provided with magic tape hair surface and magic tape hook surface at intervals. The compression hemostat can use radial bone clamping plate and ulna clamping plate to clamp radial bone and ulna from both sides of wrist to position, and bandage does not contact with the back of wrist, so that the bandage does not cause compression to the back of wrist vein, and the compression hemostat is not easy to rotate around the wrist axis, and the installation structure is relatively stable, and the probability of displacement of compression hemostat mechanism and puncture point compression failure can be reduced.

The utility model aims at providing a ulna tunnel positioner, it includes guide main body, positioning main body and locking piece, guide main body includes handle, first guide block and second guide block, first guide block sets up in one end of handle, has seted up first guide hole on first guide block, second guide block sets up in the middle of handle, has seted up second guide hole on second guide block, positioning main body includes slide and positioning hook, positioning hook sets up in one end of slide, slide is worn in first guide hole, to make the end of positioning hook away from slide be located on the extension line of the axis of second guide hole, locking piece is screwed on one end of handle close to first guide hole, locking piece is used for top contact slide. Thus, slide can slide in first guide hole, can adjust the position of positioning hook according to the anatomical structure of different patients ulna, has improved the accuracy of positioning, has adapted individual difference, and can improve the accuracy of tunnel positioning, has reduced the operation error caused by inaccurate positioning.

The application discloses an automatic elbow extension and flexion teaching device based on bone joint and muscle simulation, and relates to the technical field of elbow extension and flexion teaching.The device comprises a skeleton simulation part, a muscle simulation part, a base, a support rod, a top plate, a fixing mechanism, a driving mechanism, an electronic universal watch and a processing module.The skeleton simulation part, the muscle simulation part, the fixing mechanism and the driving mechanism are all assembled on the support frame formed by the support rod and the top plate.In the application, the flexible support frame is integrally designed with the humerus simulation part and the ulna and radius simulation part, and the movable elbow joint is formed by the fish line penetrating through the through hole, so that the human elbow joint anatomical structure and the 0-150-degree physiological activity range are accurately restored.The muscle simulation part is filled according to the human muscle shape, and is accurately attached to the first magic tape and the second magic tape, so that the muscle and the skeleton are quickly assembled, and the user can directly observe the linkage relationship between the skeleton and the muscle.

Disclosed are surgical constructs, assemblies, and methods for the repair and reconstruction of the elbow. The rotation center guide has specific dimensions configured to be fixed to either the lateral or medial side of the elbow. At one end, the guide is provided with multiple full concentric through-holes (circles of different diameters) having bisectors at 90-degree intervals to identify the rotation center on the lateral and medial epicondyles. At the other end, the guide is provided with a linear pattern of through-holes or openings located around the centerline of the guide. The linear pattern of through-holes identifies the attachment point on the ulnar tubercle. The through-holes in the concentric and linear patterns of the guide are sized to receive instruments such as K-wires, guides, and / or drill guides. One or more spikes or points are provided at the bottom of the guide for stabilization during use.

A prosthesis (1) of an amputated limb for a pet is disclosed, wherein: it comprises a main body (2) extending longitudinally, which is hollow, which is made in a single piece and which is shaped to receive a stump (3) of an amputated limb (4); the main body (2), in turn, comprises: a first part (5) extending along a first axis (A1) and forming a tubular structure; a second part (6) extending along a second axis (A2) and having a first opening (7); it comprises an end (8) which is connected to the first part (5) and which comprises an external surface (9) arranged to contact the ground during the use of the prosthesis (1) of the limb. Furthermore: the prosthesis (1) of the limb comprises anchoring means (10) which are carried by the second part (6) and which are arranged to anchor the stump (3) of the amputated limb (4) and the main body (2) to each other; the first part (5) and the second part (6) are angularly arranged with respect to each other so that the second part (6) laterally embraces part of the radius and ulna bones of the anterior amputated limb (4) or part of the tibia and fibula bones of the posterior amputated limb (4), and the first part (5) receives the stump (3) of the amputated limb (4) during the use of the prosthesis (1) of the limb.

The present invention relates to a brace configured to be worn on the forearm and hand of a human being to stabilize the wrist joint, and comprises a rigid body having an exoskeleton surrounding an elongated core. [Solution] The rigid body 12 comprises a metacarpal section 18 having (i) a ring-shaped or ring-segment-shaped thumb-holding section 20 configured to receive the thumb of a human hand, a palm section 22 configured to engage with the palm of a human hand, and an ulnar section 24 configured to wrap around the human hand from the palm side to the dorsal side; (ii) an elongated intermediate section 26 configured to engage with the medial or lateral side of a human forearm; and (iii) a forearm section 28 configured to wrap around the human forearm from the ventral side to the dorsal side.
