摘要:
A system and method for the preventing unintended surgical instruments and surgical disposables from remaining in the body cavity of a patient post surgically. Individual items are tagged with an RFID transponder tag preferably at the time of manufacture. Then, after an operation is complete, but prior to would closure, the body of the patient is scanned using an RFID reader device, such as, a hand held reader device to detect the presence of any latent RFID tags. As long as no tags are identified it is presumed that the body cavity is free of any unintended items. This avoids sponge counting and other overhead intensive methods of accounting for surgical items during a surgical procedure.
摘要:
A sensor for detecting changes in spinal tissue is disclosed. The implantable sensor or surgical instrument includes a sensing element adapted for detecting indicators of tissue health. The sensor is configured for transmitting the tissue data outside of the body. Further a system and method are provided to utilize the sensed tissue properties to treat the patient's condition.
摘要:
A surgical instrument for assessing tissue characteristics such as tissue density and volume is disclosed. The surgical instrument is hand-held and includes transducers adapted for emitting and/or receiving acoustic signals. The surgical instrument utilizes pulse-echo to determine tissue characteristics. The surgical instrument may be utilized to determine such things as the size of a lesion and whether the lesion has been completely removed or filled with graft material.
摘要:
A system and method are provided for monitoring the condition of the skeletal system and adjusting a treatment device to provide appropriate treatment in response to the sensed signal. More particularly, in one aspect the present invention is directed to a sensor for detecting changes at a spinal level and a dynamic treatment system adjustable in response to the detected changes.
摘要:
A bone regenerative composition includes a resorbable osteoconductive matrix and a multiplicity of substantially rigid nanofibers dispersed within structure of the matrix to impart structural integrity with nanofiber ends projecting out of a surface of the matrix to provide differential load bearing surface bristles.
摘要:
A debridement method, device and system or kit are effectively used to debride a lesion, particularly an osteolytic lesion resulting from a hip or knee arthroplasty. In the lesion treatment, an effective amount of a debridement fluid with suspended particulate abrasive is delivered to a lesion area within body tissue to debride the lesion; and the fluid is intermittently aspirated from the area.

Tissue removal probes comprise an elongated member, a drive shaft rotatably disposed within the member, and a rotatably tissue removal element mounted to the distal end of the drive shaft. One tissue removal element comprises a plurality of tissue-cutting filaments affixed at proximal and distal ends of the tissue removal element. The cutting filaments may have optional hinge points that allow the distal end of the tissue removal element to be inverted, thereby transforming the tissue removal element from a tissue-cutting device to a tissue-grasping device. Another tissue removal element may have a blunted tip to prevent distal tissue trauma and an irrigation port to provide irrigation fluid to the removed tissue and/or tissue removal element. Another tissue removal element has a proximal and distal spiral grooves that are oppositely pitched, so that removed tissue can be collected in the middle of the tissue removal element. Another tissue removal element has independent counter-rotating tissue removal elements to maintain stability during a bone cutting procedure. Still another tissue removal element takes the form of a drill bit with fluted cutting grooves. Yet another tissue removal element has cascading tissue-cutting notches that can be reciprocatably moved to remove tissue within a hole.
摘要:
A receptacle comprises a receptacle housing having a body, a plug interface portion extending therefrom, and a contact support member with pivot areas formed therein for urging contacts disposed in the housing into alignment. A receptacle further comprises a shielding shell having cantilevered beams formed therein. The shielding shell has a projection extending therefrom for contacting a latch arm extending from the receptacle housing. A shielding gasket is disposed around the shielding shell and has overlapping rows of beams extending therefrom. The shielding gasket also has a projection extending therefrom that is situated in a channel formed in a latch arm. The latch arm is formed as part of a latch plate comprising a latch bar, two latch arms, and at least one projection for contacting ground.

摘要:
Methods for setting contact height in an electrical connector are disclosed. Each of a plurality of electrical contacts may be seated in a connector housing such that each contact has a respective initial height relative to the housing. At least one of the contacts is pressed on such that, after the pressing, each of the contacts has approximately the same height relative to the connector housing. The pressing may bend the at least one contact at least until it has set. Before the pressing, the initial contact heights have a first tolerance. After the pressing the pressed contact heights have a second tolerance that is smaller than the first tolerance.
