摘要:
A surgical system for intra-operative and post-operative measurement of motion and position of the musculoskeletal system. The surgical system comprises a surgical navigation system configured to support the installation of at least one prosthetic component. The surgical navigation system measures motion and position of the musculoskeletal system during surgery. Holes are drilled in a first bone and a second bone of the musculoskeletal system to retain tracking devices of the surgical navigation system. Leaving the holes in the first bone and the second bone after completing the surgery can introduce stress risers that could reduce bone integrity. The surgical system includes a first implantable device and a second implantable device each having anchors corresponding to the holes of the first bone and the second bone. The first implantable device and the second implantable device each has an IMU to measure motion and position post-operatively. The anchors are configured to reduce stress risers.

A dual-mode closed-loop measurement system (100) for capturing a transit time, phase, or frequency of energy waves propagating through a medium (122) is disclosed. A first module comprises an inductor drive circuit (102), an inductor (104), a transducer (106), and a filter (110). A second module housed in a screw (335) comprises an inductor (114) and a transducer (116). The screw (335) is bio-compatible and allows an accurate delivery of the circuit into the muscular-skeletal system. The inductor can be attached and interconnected on a flexible substrate (331) that fits into a cavity in the screw (335). The first and second modules are operatively coupled together. The first module provides energy to power the second module. The second module emits an energy wave into the medium that propagates to the first module. The transit time of energy waves is measured and correlated to the parameter by known relationship.

A spine alignment system is provided to assess load forces on the vertebra in conjunction with overall spinal alignment. The system includes a spine instrument having an electronic assembly and a sensorized head. The sensorized head can be inserted between vertebra and report vertebral conditions such as force, pressure, orientation and edge loading. A GUI is therewith provided to show where the spine instrument is positioned relative to vertebral bodies as the instrument is placed in the inter-vetebral space. The system can distract vertebrae to a first height and measure the load applied by the spine region. The GUI can indicate that the load is outside a predetermined range. The spine region can be distracted to a second height where the load is measured within the predetermined load range.

A method for short range alignment using ultrasonic sensing is provided. The method includes shaping an ultrasonic pulse on a first device to produce a pulse shaped signal and transmitting the pulse shaped signal from the first device to a second device, receiving the pulse shaped signal and determining an arrival time of the pulse shaped, identifying a relative phase of the pulse shaped signal with respect to a previously received pulse shaped signal, identifying a pointing location of the first device from the arrival time and the relative phase, determining positional information of the pointing location of the first device, and reporting an alignment of three or more points in three-dimensional space. Other embodiments are disclosed.
摘要:
A post-operative pain inhibitor system comprises a controller and leads. Neuro-stimulator circuitry may be included within the patient controller or within one or more prosthetic components for generating a signal. In one example, a hip implant includes a prosthetic component having at least one electrode where the at least one electrode is configured to deliver energy pulses. Topical leads, percutaneous leads, subcutaneous leads, intraosseous leads, or leads can be placed in proximity to the operative field corresponding to the prosthetic component installation. The lead or electrodes can be coupled to neuro-stimulation circuitry to stimulate peripheral nerve fibers to affect body generated action potentials. A transmitter or power source can be housed in a prosthetic hip component. Controller can modify the pulse width, pulse shape, pulse repetition rate, and pulse amplitude of the signal thereby allowing the patient to adapt the signal to minimize their perceived pain.

A sensing insert device (100) is disclosed for measuring a parameter of the muscular-skeletal system. The sensing insert device (100) can be temporary or permanent. The sensing module (200) is a self-contained encapsulated measurement device having at least one contacting surface that couples to the muscular-skeletal system. The sensing module (200) comprises one or more sensing assemblages (1802), electronic circuitry (307), an antenna (2302), and communication circuitry (320). The sensing assemblages (1802) are between a top plate (1502) and a bottom plate (1504) in a sensing platform (121). The bottom plate (1504) is supported by a ledge (1708) on an interior surface of a sidewall (1716) of a housing (1706). A cap (1702) couples to top plate (1502). The cap (1702) is adhesively coupled to the housing (1706). The adhesive is flexible allowing movement of the cap (1702) when a force, pressure, or load is applied thereto.

At least one embodiment is directed to a system (1100) for separating at least two surfaces of a muscular-skeletal system. The system (1100) can measure a parameter of the muscular-skeletal system and align at least one of the surfaces to a mechanical axis. The system comprises disposable sensors (1106), disposable targets (1110), lasers (1114), a processing unit (1122), a display (1124), a reader (1120), a receiver (1118), spacer blocks (1102), and a distractor 1104. The sensors (1106) are in communication with the processing unit (1122) to display, process, and store measured data of the muscular-skeletal system. An alignment aid (1114, 1106) is coupled to the surface or feature of a handle of the spacer blocks (1102) or distractor (1104) to measure alignment to the mechanical axis. Several of the system components are disposed of after the surgery is completed. Measurement data is stored in memory by processing unit 1122.
