Abstract:
PROBLEM TO BE SOLVED: To provide a manufacture method of a low cost electric surgical instrument having an elastic conductor to be put buried in a mold injected housing. SOLUTION: An electric surgical instrument 10 is equipped with an elastic conductor 18 to be put buried in a mold injected housing 11. The conductor 18 stretches out of the terminal of a generator for electric surgery through the instrument and applied onto a patient electrode 15 on its top 12. Cost of the instrument 10 is reduced as it is made possible to get rid of complicated fixture process of the conductor arising from putting a hard conductor 18 in the mold injection process. Its manufacturing cost is as well reduced as it is possible to apply the patient electrode onto the conductor 18 before assembling an instrument housing.
Abstract:
A bipolar electro-surgical instrument for vessel sealing comprises first, and second members (13, 14) connected by a pivot (15). A pair of jaws (19, 20) have opposable seal surfaces that are designed to grasp vascular tissue, and conduct bipolar electro-surgical current therethrough. Electrodes (11, 12) on the jaws, including the seal surfaces (25) are removable, and disposable. The jaws of the instrument have mechanical interfaces (22, 23) designed to accept replacement electrodes. The instrument further comprises interlocking ratchets (29, 30) designed to hold a constant closure forces between the seal surfaces. Wires (26, 27) extend from the electrodes along one of the members, and are connectible to an electro-surgical generator.
Abstract:
A bipolar electro-surgical instrument (10) has opposable seal surfaces (18, 19) on its jaws (16, 17) for grasping, sealing vessels, and vascular tissue. Inner, and outer instrument members (11, 12) allow arcuate motion of the seal surfaces. An open lock box (13) provides a pivot with a lateral support to maintain alignment of the lateral surfaces. Ratchets (25, 26) on the instrument members hold a constant closure force on the tissue during the seal process. A shank portion (14, 15) on each member is tuned to provide an appropriate spring force to hold the surfaces together. During surgery the instrument can be used to grasp, clamp vascular tissue, and apply bipolar electro-surgical current through the clamped tissue. In one embodiment, the seal surfaces are partially insulated to prevent a short circuit when the instrument jaws are closed together. In another embodiment, the seal surfaces are removably mounted on the jaws.

Abstract:
The instrument has a single flexible conductor embedded in an injection moulded instrument housing (13) which can be held by a surgeon and which is coupled to an HF generator at one end and to a patient electrode at the distal end of the instrument. The instrument housing is formed as a pair of clamp arms (22,23) which can be moved together to clamp the tissue between their free ends (31), one of which incorporates the patient electrode.
