    Abstract: A biopsy device comprises a needle, a body portion, and a needle firing assembly. The needle firing assembly is operable to fire the needle distally relative to the body portion. The needle firing assembly includes two translating members, a resilient member, and a motor. The motor is operable to selectively move the first translating member distally and proximally. The second translating member is secured relative to the needle such that the needle and the second translating member translate unitarily. The resilient member compresses as the first translating member is moved distally toward the second translating member. The first translating member is then secured to the second translating and the translating members are moved proximally while holding the resilient member in the compressed state. The second translating member is released from the first translating member when they reach a proximal position, which allows the resilient member to fire the needle distally.

  • Patent number: 9427254
    Abstract: An embodiment of the present invention provides a kit of parts for use in a surgical procedure performed under image guidance, and particularly under real time image guidance. The kit includes a sterilized drape for use with the chosen imaging machine and which can be used to provide a sterile operating environment when the procedure is performed under the imaging beam. The kit also includes a needle holder that can keep the surgeon's hand away from the imaging beam. The needle holder is operable to hold a needle that is made from a material suitable for piercing tissue, but also substantially preserves the appearance of the needle when it is viewed under the imaging beam.

  • Patent number: 9332972
    Abstract: An aspiration apparatus includes a barrel having a needle receiving end and a piston receiving end. The barrel has an inner diameter and an outer diameter. The piston receiving end of the barrel has substantially the same inner diameter as the inner diameter of the barrel. The barrel has an opening therein through a sidewall of the barrel. The opening is between the needle receiving end and the piston receiving end. The opening is distant from the needle receiving end. The aspiration apparatus also includes a needle sealingly attached to the needle receiving end of the barrel, and a piston having an end which substantially seals to the inner diameter of the barrel. The piston is capable of a number of positions including a first position near the needle receiving end, a third position past the opening in the barrel.

  • Patent number: 9308013
    Abstract: A surgical tool can include a main unit and a first rigid sheath. The main unit includes an inner tube that is received within an outer tube. The first rigid sheath removably receives the main unit and connects to the main unit via a coupling between a first connector portion of the main unit and a second connector portion of the rigid sheath. The first rigid sheath can be completely removed from the main unit when the first connector portion is decoupled from the second connector portion. A different rigid sheath having a different shape from the shape of the first rigid sheath can then be removably attached to the main unit instead of the first rigid sheath. A surgical tool kit includes a plurality of rigid sheaths having different shapes and having the ability to be removably attached to the main unit.

  • Patent number: 9192439
    Abstract: A method of manufacturing a surgical instrument includes charging a first component to a first voltage, charging a second component to a second voltage such that a pre-determined voltage differential is established between the first and second components, axially moving at least one of the first and second components relative to the other, monitoring an electrical characteristic to determine whether an axial distance between the first and second components is equal to a target axial distance, and retaining the first and second components in fixed position relative to one another once the axial distance between the first and second components is equal to the target axial distance.

  • Patent number: 9179845
    Abstract: An optical sharp fibrous needle probe includes an optical fiber in a hollow needle ending in a cutting point. The optical fiber is inserted and bonded in the hollow of the needle and then polished to take on the exact needle cutting shape. The material to be explored is pricked by the needle. A light injection and recovery device is placed at the inlet of the fiber. The material located at the sharp end of the needle backscatters the incident light and generates an endogenous fluorescence signal. A part of this luminous flux is recovered by the point of the needle and sent back to the injection and recovery device. The same analyses the light in strength, duration and wavelength and enables a diagnostics without taking the in-depth explored material. An optical telemeter placed on the outer tip of the needle enables the depth of the explored area to be known.

  • Patent number: 9161743
    Abstract: A biopsy apparatus includes a cannula, a cutting sheath, and a pressure generating device. The cannula has a lumen, a proximal portion, a closed distal end, and an orifice located on a circumferential surface of the cannula. The orifice is configured to receive a tissue sample into the lumen of the cannula. The cutting sheath is coaxially disposed with the cannula. The cutting sheath is configured to be movable relative to the cannula to selectively cover the orifice. The pressure generating device is coupled to the proximal portion of the cannula. A bifurcated valve assembly is interposed between the cannula and the pressure generating device. The bifurcated valve assembly has a first valve configured to release pressure into the lumen of the cannula and has a second valve configured to facilitate an inflow of air into the pressure chamber of the pressure generating device.

  • Patent number: 9089317
    Abstract: A method is provided for calibrating a surgical biopsy system. The biopsy system includes a biopsy instrument and control unit. The biopsy instrument includes a piercer, rotatable cutter, and a port for receiving tissue samples. The method comprises the steps of translating the cutter distally until the translation of the cutter is stopped at an extended position and recording the extended position. The cutter is then translated from the extended position proximally until the translation of the cutter is stopped at a retracted position proximal to the extended position. The retracted position is recorded. The method further comprises the step of rotating the cutter to a rotation speed while the cutter is located at the retracted position and, if determined that the rotation speed is within a predetermined rotation speed range, a feedback signal is provided on the display allowing the operator to progress to the next procedural step.
