摘要:
A pulsed irrigation handpiece comprises a pulsed irrigation liquid outlet for applying liquid pulses to a surgical site, a pump unit reciprocatingly driveable for pumping pulses of irrigation liquid through the outlet, an electric powered drive unit for reciprocatingly driving the pump unit, and a housing containing the pump and drive units. A irrigation inlet hose leads from the pump unit out of the handpiece housing and is connectable to a remote irrigation liquid source. An irrigation inlet hose adjacent the remote end thereof and electric conductors extending along the irrigation inlet hose transfer electric power from the supply unit to the drive unit in the handpiece. Removable tips are alternatively removably attachable to the irrigation liquid outlet adjacent the front end of the handpiece.
摘要:
A medical/surgical irrigator comprising a handpiece and a tip assembly that is removably attached to the handpiece. Internal to the handpiece is a variable speed pulse pump from which irrigation fluid is discharged through the tip assembly. A single, variable speed motor regulates the pumping rate of the pump. The tip assembly includes a suction wand through which the discharged fluid is drawn away from the site to which the fluid is applied.

An apparatus, method, and system for the deployment of surgical mesh material, which are particularly suited for use in the laparoscopic surgical repair of hernias. Any suitable surgical mesh can be placed between at least two elongate retaining members; wrapped around the elongate retaining members; inserted into a patient; and then deployed using at least two elongate deploying members on either side of the mesh.

A bone cement mixing and delivery system including a mixer and a delivery device. The mixer includes a paddle for mixing the components and a piston that pushes the mixed cement into the attached delivery device. The delivery device includes a tube into which the bone cement is forced from the mixer, and a plunger that forces the cement out of the tube during the medical procedure. The tube includes an entry port through which cement is introduced into the tube from the mixer. A one-way valve attached to the tube allows the cement to flow from the mixer through the entry port. After the cement is loaded in the tube, the delivery device is removed from the mixer. The valve blocks flow out of the entry port when the plunger is depressed.

A bone cement mixing and delivery system is provided in which separate components of bone cement are mixed together in a mixer to form a bone cement mixture. The mixer includes a mixing paddle and a mixing shaft connected to the mixing paddle. A motor operatively engages the mixing shaft to rotate the mixing shaft and the mixing paddle to mix the components in a mixing chamber. The motor also operatively engages a transfer mechanism. After a predetermined mixing period has elapsed, the motor automatically actuates the transfer mechanism to transfer the mixture to a delivery device. The mixture is then delivered to a target site, such as a vertebral body of a patient or other anatomical site.

A medical/surgical irrigating handpiece with both a discharge line through which fluid is applied to the site and a suction line through which the discharge fluid is drawn away. The handpiece has a variable speed pulse pump. A single, variable-speed motor actuates the pump to regulate the pumping rate. Power to actuate the motor comes from a battery pack that remote to the handpiece. A control mechanism attached to the handpiece regulates the energization signal applied to the motor so as to regulate motor speed.

A tip unit is removably affixed to and extends forward from the barrel of a surgical handpiece, for fluid transfer with respect to the surgical site. The tip unit includes a casing extending forward from the handpiece barrel and a fluid transfer tube extending forward from the casing. The fluid transfer tube extends in sealed relation through axially aligned holes in the front and rear walls of the casing for connection with a fluid transfer unit in the handpiece. A lamp at the far end of the tube is energized by a battery unit in the casing under control of a switch accessible at the outside of the casing. A light transmitting enclosure at the far end of the tube protects against liquid contact with the lamp.

A bone cement mixing and delivery system including a mixer, a delivery device, and a flexible extension tube. A connector is attached to a distal end of the flexible tube. The connector includes a housing, a spindle configured with a fitting, and an enlarged knob. The spindle is seated within the housing and is configured to rotate between a closed and open position. In the open position, the spindle allows flow from the delivery device flexible extension tube into a bore of the spindle and into the spindle fitting. A delivery cement cannula is attached to the spindle fitting for allowing cement to travel from the delivery tube into living tissue. The enlarged knob is used to rotate the spindle from an open to a closed state and vice versa.
摘要:
A needle protector having a body, a needle hub and a needle. The body includes a first end and a second end. The body consists of a hollow elongated cylinder defined by a continuous wall having a channel extending between the first and second ends. The continuous wall defines a recess adjacent the first end. The needle hub is movably mounted on the body. The needle hub has an external portion, an internal portion and a tracking member extending between the external portions. The tracking member is positioned in the channel. The external portion includes a single locking arm adapted to be received by the recess and the second end. The needle is mounted in the internal portion of the needle hub. Movement of the needle hub from the first end to the second end results in corresponding movement of the needle into the body until the locking arm engages the second end thereby preventing movement of the needle hub and the needle from the second end to the first end of the body.
