A device and system for inserting and impacting bone dowel allografts or bone chips into a bone tunnel. The surgical impacting system includes a surgical tamp having a proximal end and a distal end with an elongated shaft extending therebetween. The surgical tamp has an inner channel extending therethrough from the proximal end to the distal end. The distal end of the surgical tamp can have a distal tip. The surgical tamp may have a handle at the proximal end or a proximal tip at the proximal end. The surgical tamp may also have one or more slots extending through the exterior surface of the elongated shaft and into the inner channel. The surgical tamp can be configured for insertion into a delivery tube. The delivery tube serves the purpose of containing a bone dowel or bone chips therein for smooth insertion into the joint.

A unique, universal Zero-Profile Expandable Intervertebral Spacer (ZP-EIS) device for fusion and distraction throughout the entire spine is provided which can be inserted via anterior, anterolateral, lateral, far lateral or posterior surgical approaches dependent on the need and preference. Multiple ZP-EIS embodiments each with unique mechanisms of calibrated expansion are provided. Two of these embodiments incorporate bi-directional fixating transvertebral (BDFT) screws and five other embodiments do not incorporate BDFT screws. A tool for implantation into the intervertebral device and calibrated device expansion is also disclosed.

An orthopedic impacting tool comprises a motor, a linear motion converter, an air chamber, a compression piston, an impacting element, an anvil element, and a broach adapter. The compression piston may cause the impacting element to apply controlled force on a broach adapter to create a precise opening for subsequently disposing a prosthesis in a patient. The tool allows forward or backward impacting for expanding the size or volume of the opening or for facilitating removal of the broach and tool from the opening. A force adjustment control of the tool allows a user to increase or decrease the impact force. A light source and hand grips improve ease of operation of the tool.

This invention provides optimized solid substrates for promoting cell or tissue growth or restored function, which solid substrate comprises aragonite and is characterized by a specific fluid uptake capacity value of at least 75%, or a contact angle value of less than 60 degrees when in contact with a fluid and which is further characterized by tapered sides and tools for implantation of optimized solid substrates.

In an illustrative embodiment, a motor-driven orthopedic impacting tool for orthopedic impacting in the hips, knees, shoulders and the like may be capable of holding a surgical implement such as a broach, chisel, or other end effector, which when gently tapped in a cavity with controlled percussive impacts, can expand the size or volume of an opening of the cavity or facilitate removal of the surgical implement from the opening. A stored-energy drive mechanism may store potential energy and then release it to launch a launched mass or striker to communicate a striking force to an adapter in either a forward or reverse direction. The tool may further include a combination anvil and adapter and an energy adjustment mechanism to adjust the striking force the launched mass delivers to the adapter.

There invention relates to a handle (100) for coupling to orthopaedic surgical instruments used in joint arthroplasty. The handle is universal. The handle comprises a body (102) having a proximal end (106), a distal end (104), and an open-ended channel (108) extending between the distal end and the proximal end. The channel is configured for receiving a shaft of a first orthopaedic instrument (10) such that the shaft extends completely through the handle, and the handle is in a sliding relationship with the shaft. The channel is also configured for separately and independently receiving a handle-attachment portion located at a proximal end of a second orthopaedic surgical instrument (500, 502, 504) such that the handle and the second orthopaedic surgical instrument are held in a fixed relationship.

The invention provides a pair of dual-purpose forceps, comprising a first forceps body and a second forceps body. When the first forceps body is connected with the second forceps body by means of a first pressurizing connecting member and a second pressurizing connecting member, a first handheld member and a second handheld member move towards each other, and a first pressurizing functional member and a second pressurizing functional member also move towards each other to complete pressurizing; when the first forceps body is connected with the second forceps body by means of a first opening connecting member and a second opening connecting member, the first handheld member and the second handheld member move towards each other, and a first opening function member and a second opening function portion face away from each other to complete opening. The dual-purpose forceps is simple in structure and is operated conveniently so that the double-purpose forceps can switch freely between opening and pressurizing functions conveniently and quickly.

A fixing device and an installation tool and a fixing method of the cranial flap, wherein the installation tool comprises a driving part, a loading part and an over torque protection mechanism disposed between the driving part and the loading part, the driving part drives the loading part to rotate by the over torque protection mechanism, the loading part is used for tightening the cranial flap fixation device, when the torque of the driving part acting on the over torque protection mechanism is larger than the threshold value, the over torque protection mechanism will be separated from the driving part and/or the loading part. The present invention not only effectively improves the installation and disassembly efficiency of the installation tool, but also eliminates hidden safety hazards caused by uncertainties caused by human factors in the tightening process, significantly improves the safety of the installation process.

Technologies for monitoring impaction and predicting impaction state during an orthopaedic surgical procedure include one or more impaction sensors that generate sensor data. The surgical procedure includes impaction of an orthopaedic implement such as a surgical instrument or a prosthetic component. An impaction analyzer generates an impaction state prediction with a machine learning model based on the sensor data. The impaction state prediction may include an unseated state, a seated state, and a fracture state. An impaction state user interface outputs the impaction state prediction. A model trainer may train the machine learning model with labeled sensor data.

A system and methods are provided for treating radial head fractures. The system includes an implant, a sterile instrument kit for radial head arthroplasty, and a head sizer and assembly tray for sizing and assembling implants. The implant includes a head that is coupled with a stem. The head is adapted to be placed into sliding contact with a capitellum of the radiocapitellar joint. The stem is configured to be inserted into a hole reamed into a medullary canal of the radial head. The sterile instrument kit comprises a multiplicity of instruments including any one or more of trial heads and trial stems, a starter awl, a reamer, a planar, an inserter cap, and an impactor. The instruments are configured for implanting the implant into the radiocapitellar joint such that the implant restores biomechanical properties of the joint.
