The utility model belongs to the field of slippage reduction tools, and particularly relates to an anterior cervical spondylolisthesis reduction tool which comprises an adjusting pipe, a fixing frame is fixedly connected to the left portion of the outer side of the adjusting pipe, an opening frame is slidably connected to the right portion of the outer side of the adjusting pipe, and a screw rod is installed in the adjusting pipe through a bearing. A limiting wheel is fixedly connected to the right end of the screw rod, a rotary knob is fixedly connected to the right end of the limiting wheel, a locking mechanism is arranged on the outer side of the adjusting pipe, a mounting pipe is fixedly connected to the ends, away from the adjusting pipe, of the fixing frame and the opening frame, and an inner threaded pipe is fixedly connected to the interior of the mounting pipe; and the interior of the internal threaded pipe is connected with a screw through a thread. Due to the fact that the screw, the inner threaded pipe, the T-shaped base and other structures are additionally arranged on the installation pipe, the installation pipe can be installed on the fixed outer side of the cervical vertebra through the screw in the using process, and therefore the tool can be more stable during resetting, and slipping is avoided.

This invention belongs to the field of medical technology and discloses an anatomically optimized spinal disc fusion cage and its design method. Based on the patient's personalized three-dimensional anatomical information of the diseased intervertebral disc, a personalized overall intervertebral fusion cage is designed. The designed overall intervertebral fusion cage is segmented into different types of personalized AOFS intervertebral fusion cages; these different types of personalized AOFS intervertebral fusion cages include, but are not limited to: ALIF (anterior fusion cage), PLIF (posterior fusion cage), TLIF (lateral posterior fusion cage), and LLIF (lateral fusion cage). This invention proposes a novel anatomically optimized spinal disc fusion cage design tailored to individual patients, fully integrating the advantages of simple decompression and decompression plus fusion surgery techniques. Its purpose is to optimize the biomechanical environment of adjacent segments after fusion surgery, reduce or prevent the possibility of reoperation after the initial fusion surgery, and thus prolong the surgical lifespan.

An implant system comprising one or more staple and a cage is disclosed. The implant system is secured to a bone by moving the staple whereby tines of the staple frictionally and mechanically engage or embed themselves in the bone sidewalls. In some embodiments, the staple comprises a first staple and a second staple. In some embodiments, the staples are positioned transverse to an approach trajectory of positioning of the implant system. The implant system may be configured for use as an interbody or intrabody implant system. The implant system may further comprise tools for positioning the implant system. Some embodiments of the implant system are configured to be positioned from an anterior trajectory, an anterior lateral approach trajectory, or an anterior oblique approach trajectory relative to the bone. Some embodiments of the system are configured to be used in an anterior lumbar interbody fusion (ALIF) procedure.

The invention discloses a proximal femur lifting device for direct anterior approach hip replacement, which belongs to the technical field of medical instruments and comprises a fixing unit, a multi-stage positioning arm, a base plate, a support column, a lifting slider, a stepping lifting mechanism and a prying and lifting support. The fixing unit is used for being installed on the operating bed side. The multi-stage positioning arm is connected with the fixing unit and the base plate and can adjust the position of the base plate; the supporting column is vertically erected on the base plate; the lifting sliding block is sleeved on the supporting column and is driven by the stepping lifting mechanism to lift; the prying and lifting support is fixed to the lifting sliding block, and a supporting clamping groove is formed in the prying and lifting support. By means of the structure, a stable force application fulcrum with the height and the angle capable of being adjusted in multiple directions is provided for the operation bone pry, the problems that in the prior art, operation is not stable, and control is difficult are solved, and safe, controllable and stable lifting of the proximal femur can be achieved.

The invention discloses a split fusion cage compatible with direct decompression and end plate conformal bone grafting of an anterior spinal flexible robot. The split fusion cage comprises a first main body section, a second main body section and a third main body section, the first main body section is L-shaped and comprises a longitudinal supporting part and a transverse supporting part, and a first connecting part is arranged at the end, away from the longitudinal supporting part, of the transverse supporting part; the first main body section is provided with an inlet side parallel to the transverse supporting part and an outlet side parallel to the longitudinal supporting part, and the first main body section is used for enabling the flexible mechanical arm to enter and penetrate out of a spinal canal to extend into the spinal canal for direct pressure reduction operation; the second main body section is detachably connected to the first connecting part, and a U-shaped structure with a bone grafting cavity is defined by the second main body section and the first main body section; the third main body section is of a plate-shaped structure, and an O-shaped structure is defined by the third main body section, the second main body section and the first main body section. A split structure is adopted, an access channel and an operation space are provided for the flexible mechanical arm, direct pressure reduction operation is facilitated, in-vivo bone grafting can be carried out, and the adaptation of a bone grafting object and an end plate in shape is increased.

An orthopedic system for use in direct anterior approach orthopedic hip replacement procedures for the femur of a patient includes a stem insertion device (12) having an offset locking shaft (68) for placing a cementless femoral stem (14) component into the surgically prepared intramedullary canal of the patient.

Devices, systems, and methods configured to treat spinal deformities, such as anterior scoliosis correction. A bilateral anterior system may include a bilateral anterior screw having a threaded shaft with modular connectors at each end. The bilateral anterior screw is configured to extend completely through a vertebral body such that the modular connectors are exposed on both sides of the vertebral body. An ipsilateral construct including a first rod or cord is securable to the modular connector on an ipsilateral side, and a contralateral construct including a second rod or cord is securable to the modular connector on a contralateral side, thereby completing a bilateral stabilization.
