摘要:
Tissue localization devices and methods of localizing tissue using tissue localization devices are disclosed. The tissue localization device can comprise a handle comprising a delivery control, a delivery needle extending out from the handle, and a localization element within the delivery needle. The localization element can be deployed out of the delivery needle or retracted back into the delivery needle when the delivery control is translated in a first direction or a second direction, respectively. The localization element can be coupled to a flexible tracking wire.

A system, device and method for insertion of a penetrating member into tissue is disclosed, which may be handheld and automated. A detector obtains data regarding subdermal locations of tissue structures, including cavities such as blood vessels. A processor calculates the distance between a preselected target point below the tissue surface, such as within a blood vessel, and the tissue surface, and adjustment data for vertical, angular and extension adjustment of the penetrating member. Vertical, angular and extension actuators carry out the adjustments in real-time as calculated and directed by the processor. Changes in the location of the target point result in automatic recalculation and adjustment by the processor and various actuators. A vibrational actuator induces vibration to the penetrating member during insertion, overcome tissue deformation and vein rolling. A guidewire may be inserted through or by the device, for dilator and catheter insertion once the penetrating member is removed.

A single-use compression lancing device includes a bottom housing, a top housing, and a lancet. The lancet is generally within the bottom and top housings. The top housing is configured for slidingly engaging the bottom housing such that manipulation of the top housing relative to the bottom housing causes a sharp tip portion of the lancet to protrude from an opening of the top housing. In one form, at least one arm extending from the lancet interengages a portion of the top housing such that the lancet is retracted within a portion of the bottom housing.

According to an aspect of the present disclosure, an end effector for use with a surgical device is provided. The end effector includes a drive assembly, a driver, a needle assembly and a biasing element. The driver is disposed in mechanical cooperation with the drive assembly. Rotation of the drive assembly in a first direction causes distal translation of the driver with respect to the drive assembly. The needle assembly is disposed in mechanical cooperation with the driver. Distal translation of the driver causes a corresponding distal translation of the needle assembly. The biasing element is disposed in mechanical cooperation with the needle assembly and is configured to bias the needle assembly proximally.
摘要:
A device that uses an anatomic landmark or fiduciary point to establish a point of origin for device orientation in space is provided. The device controls the direction and depth of delivery of a needle, wire, trocar or cannula utilized for diagnostic or therapeutic intervention. The device guides the percutaneous delivery of a needle, wire, trocar or cannula to a target spatial location on or within tissue.
摘要:
The present invention discloses a camera holder device and mechanism for laparoscopic surgery. The camera holder device is easily installed and disassembled, comfortable to use, not limiting the dexterity of the surgeon, having small physical dimension and inexpensive. Furthermore, the present invention relates to means and methods for improving the interface between the surgeon and the operating medical assistant or between the surgeon and an endoscope system for laparoscopic surgery.. Moreover, this present invention discloses a device useful for controlling an endoscope system for laparoscopic surgery, in which the endoscope is inserted through a small incision into the body's cavities.
摘要:
An apparatus (1) for positioning a medical instrument (2) with respect to a target tissue (3) comprises reference means (9) with a plurality of guide channels (11) to allow the medical instrument (2) to pass in a guided manner, processing means (8) which determine a misalignment magnitude between at least one of the guide channels (11) and a target position (30) in the target tissue (3), transversal adjusting means (38) which allow the position of the reference means (9) to be adjusted so as to compensate for the misalignment between the target position (30) and the guide channel (31).

摘要:
A positioning apparatus including a needle holder having a through hole for regulating needle placement and movement, a needle positioning unit, and an engagement member that fixes a position of the needle holder with respect to the needle positioning unit. The needle holder is either least partially detachably attached to the needle positioning unit or deformable. The positioning apparatus may be designed to accommodate the placement of multiple needles.
