An apparatus includes a template which locates hole positions in a jawbone while the template is separated from the jawbone by gum tissue. The template follows a contour of the gum tissue surrounding the jawbone and has guide holes which receive a cutting tool. Anchoring elements attach the template to the jawbone. A system includes means for scanning an implantation site on a patient's jawbone, simulating the implantation site, and determining nerve-rich areas or nerve paths in the jawbone. A holed template is produced which is separated from the jawbone by at least gum tissue of the patient. Attachment hole positions in the jawbone are located so as to avoid nerve paths. A method of forming holes to attach a dental implant to a patient's jaw bone without surgical intervention in gum tissue of the patient to expose the jawbone is disclosed which avoids impingement on a nerve path.

The practice pad is mounted on a folder or portfolio for convenient access and use by the student or practitioner, the portfolio also including pictorial illustrations showing various proper suturing techniques as a visual guide to the user in practicing suturing procedures.

A surgical training aid apparatus for facilitating the training of medical procedures comprising a housing and an anatomical replicating assembly. The housing includes a tray having a bottom surface and a top surface opposite the bottom surface. The anatomical replicating assembly is positioned upon the top surface of the tray of the housing, and includes a base layer and at least one body component. The base layer has a bottom surface and a top surface, and, overlays a portion of the top surface of the tray of the housing. The base layer further includes a tackiness. The body component is positioned between the top surface of the housing and the bottom surface of the base layer or on the base layer. The body component likewise includes a tackiness. The body component is releasably coupled to the base layer due to the tackiness of the two components, wherein the tackiness is overcome so as to separate the at least one body component relative to the base layer.

Provided is an articulation for surgical equipment using a ball joint fastened by the ball joint. The present invention has been made in an effort to provide an articulation for surgical equipment using a ball joint of which the shaft of pitching or yawing is not changed even though the pitching or the yawing is repeated. The articulation for surgical equipment using a ball joint is configured to include a plurality of disks; a ball joint to allow the plurality of disks to be pitched or yawed between the plurality of disks based on a longitudinal direction of the articulation for surgical equipment; and a driving wire applying a driving force to pitch, yaw, or roll the plurality of disks. According to the articulation for a surgical equipment using a ball joint according to the embodiment of the present invention, the rotating shaft of the articulation is not changed despite the repeated movement of the articulation, and since the durability of the articulation is increased, the safety of the surgical equipment can be improved when the articulation is applied to the surgical equipment.

An ophthalmic surgical system 10 detects a change in a viscosity of a material being aspirated from an eye 32. The system 10 includes a control module 18 connected to an aspiration pump 20, and a flow meter 19 connected to the control module 18 and the aspiration pump 20. The flow meter 19 provides a flow rate of material aspirated from the eye 32 by the aspiration pump 20. A surgical handpiece 24 connected to the aspiration pump 20 and the control module 18 is inserted into the eye 32 during surgery. The control module 18, during surgery, detects a step change in the flow rate of material aspirated from the eye 32 and the control module 18 further causes the surgical system 10 to alert a surgeon that a change in viscosity of the material being aspirated has been detected indicating that the handpiece 24 has moved from a material of a first viscosity to a material of a second viscosity.

Aspects of the present disclosure relate to approaches for determining position and orientation of a tracked tool in a medical navigational context. In one embodiment, the position of a surgical or interventional tool may be determined using the orientation or field direction data such that the determination is independent of field strength or magnitude. Feedback may be provided to a user based on these determinations. In certain embodiments, the navigational system may be auto-calibrated using position information determined independent of field strength or magnitude.
