摘要:
Sinusitis, mucocysts, tumors, infections, hearing disorders, choanal atresia, fractures and other disorders of the paranasal sinuses, Eustachian tubes, Lachrymal ducts and other ear, nose, throat and mouth structures are diagnosed and/or treated using minimally invasive approaches and, in many cases, flexible catheters as opposed to instruments having rigid shafts. Various diagnostic procedures and devices are used to perform imaging studies, mucus flow studies, air/gas flow studies, anatomic dimension studies and endoscopic studies. Access and occluding devices may be used to facilitate insertion of working devices such asendoscopes, wires, probes, needles, catheters, balloon catheters, dilation catheters, dilators, balloons, tissue cutting or remodeling devices, suction or irrigation devices, imaging devices, sizing devices, biopsy devices, image-guided devices containing sensors or transmitters, electrosurgical devices, energy emitting devices, devices for injecting diagnostic or therapeutic agents, devices for implanting devices such as stents, substance eluting or delivering devices and implants, etc.
摘要:
The invention relates to a medical instrument having a hollow shaft, a tool positioned on the distal end of the shaft consisting of a rigid jaw member and a jaw member that can rotate with respect to the rigid jaw member, as well as a handle positioned on the proximal end of the shaft. The tool and the handle are in active connection with one another by a push-pull rod mounted in the shaft, and the jaw members of the tool are mounted on one another by pins. It is proposed with the invention that the push-pull rod should be configured as a hollow slide tube mounted in the shaft so that it can slide axially and is in active connection with the rotatable jaw member by an actuation element that is essentially rod-shaped.

A surgical kit is used for performing an anterior cervical disectomy, the surgical kit having a sheath that is inserted into a mammal by using a bullet coupled to the sheath and impacting on the bullet. Various cutters, including a cervical cutter having a drill tip end, a serrated cutter having an enclave for receiving cutting spoils therein, and a deburrment cutter having a burr end, are insertable through the sheath for cutting bone and disc matter. An impactor can be used to move the sheath within the mammal during use of the serrated cutter and deburrment cutter without the need to remove either tool. A pituitaries is used to remove loose bone and disc material.

摘要:
Devices and methods for creating holes in the articular process of the vertebra are provided. One embodiment of the invention comprises a drill head comprising a frame, punch arm with punch tip and opposing plate. Methods of using the resulting holes to anchor or stabilize facet joint prosthesis, and also altering the spacing and motion at the facet joints of the vertebral column, are provided.

摘要:
A method includes forming an incision in a body at a location apart from a mid-line axis defined by a portion of a spinal column including a first pair of adjacent spinous processes. A first support member is inserted percutaneously through the incision into a space between the first pair of adjacent spinous processes. A second support member is inserted percutaneously through the incision into a space between a second pair of adjacent spinous processes different from the first pair of adjacent spinous processes.

A method includes moving a spinal implant such that a central portion of the spinal implant is disposed between adjacent spinous processes, radially extending a proximal portion of the spinal implant on a first side of the adjacent spinous processes such that movement of the proximal portion between the adjacent spinous processes is inhibited, and radially extending a distal portion of the spinal implant on a second side of the adjacent spinous processes opposite the first side such that movement of the distal portion between the adjacent spinous processes is inhibited.
摘要:
A handle for surgical instruments that has a “wishbone” configuration. In one embodiment, the instrument is provided with a ratchet mechanism allows two operating handles to be locked in a predetermined position (for example, when the surgical instrument that is maneuvered is in use) or to move relative to each other when the ratchet is partially or fully released (for example, when the surgical instrument that is maneuvered is not in use). In another embodiment, the instrument is provided with a rotary gear mechanism.
摘要:
The invention relates to a medical cutting and/or holding instrument having a shaft, a handle consisting of two gripping members that is positioned on the proximal end of the shaft, and a push-pull rod mounted in a guide groove of the shaft to actuate a tool consisting of two jaw members that is positioned on the distal end of the shaft, such that for opening and closing the tool the push-pull rod can be coupled on the distal end with at least one rotatable jaw member of the tool and on the proximal end with a rotatable gripping member of the handle, and such that the push-pull rod and the rotatable gripping member can be dissolubly connected with one another by a coupling mechanism. To produce a medical cutting and/or holding instrument that can also be used for endoscopic purposes, it is proposed with the invention that the push-pull rod is coupled with the rotatable components both on the proximal and the distal ends with free play in a direction essentially perpendicular to the direction of motion of the push-pull rod.
