The application discloses a cutting guide plate for a proximal tibia and a preparation method thereof, and belongs to the technical field of orthopedic cutting guide plates. The cutting guide plate comprises a positioning plate, the bottom surface of the positioning plate is attached to a tibial articular surface and lateral bone, a cutting groove is formed in the side surface of the positioning plate, the cutting groove is inclined backward by 3-5 degrees, an avoiding hole is formed in the top surface of the positioning plate, and at least two fixing holes are arranged on the positioning plate; and a positioning line is arranged on the upper end surface of the positioning plate, and the positioning line is used for pointing to the inner 1 / 3 of a tibial tuberosity. The cutting guide plate is used for tibial cutting surgery, effectively improves the cutting and prosthesis installation accuracy, shortens the operation time, reduces the operation complications, and helps the patient to quickly recover.

The utility model relates to the technical field of medical instruments, in particular to an anterior cruciate ligament tibial insertion avulsion fracture bone crushing mesh enclosure with lines, which comprises a mesh enclosure main body, two first suture lines, two second suture lines and two third suture lines, the two first suture lines are located at the same end of the mesh enclosure main body, the two first suture lines are symmetrically arranged relative to the mesh enclosure main body, the two second suture lines and the two third suture lines are located at the same end and located on the side opposite to the first suture lines, and the two second suture lines and the two third suture lines are symmetrically arranged relative to the mesh enclosure main body; the two first suture lines are arranged in a pre-formed front-end bone tunnel in a penetrating mode, the two second suture lines are arranged in a pre-formed rear-end bone tunnel in a penetrating mode, and the two third suture lines are wound on the anterior cruciate ligament. The fixing device has the advantages that broken bones in the tibial tuberosity avulsion fracture area of the anterior cruciate ligament can be fixed, and the surgical treatment effect is improved.

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.

This device is an acupressure device for applying pressure to the pelvic floor. It is molded from a resin material with moderate elasticity, and is compact, palm-sized, with a length D1 of approximately 90 mm at its widest point and a height D2 of approximately 59 mm. The user places the device on a seat, such as a chair or the floor, sits on it, and applies pressure to the pelvic floor using their body weight. When the user sits on the device, the multiple protuberances 11-14 press from below on the left and right areas of the user's pelvic floor, bounded by the ischial ramus, ischial tuberosity, sacrotuberous ligament, anus, and coccyx. This allows the device to loosen these areas, which are areas that can be effectively used to improve urinary incontinence. Of the protuberances 11-14, protuberances 11 and 12 correspond to the user's left pelvic floor, and protuberances 13 and 14 correspond to the user's right pelvic floor. Additionally, the bottom surface of this product, which is the surface that rests on the seat, is formed convexly in the front-to-back direction of the user when they are sitting on the product. This induces forward and backward tilt of the pelvis, allowing the user to naturally apply appropriate pressure to the left and right pelvic floors to massage and loosen them. The front and back directions of the user when using this product are indicated by the arrows in "Reference Figure 2 Showing the Names and Sizes of Each Part." The symbols in the above explanation are attached to "Reference Figure 1 Showing the Names and Sizes of Each Part" and "Reference Figure 2 Showing the Names and Sizes of Each Part."
