  • Patent number: 5476090
    Abstract: The sheath according to the present invention comprises the hard sheath member which can cover the entire hard insertion tube of the hard endoscope and the soft sheath member. So, when the hard insertion tube is inserted into the body cavity of a patient, it will not possibly be contaminated with the blood, bacteria or the like. The hard insertion tube can be used for a next endoscopy without the necessity of sterilization or disinfection. Also according to the present invention, the soft sheath member is fitted closely over the controller, so that the controller can be operated from outside the soft sheath member without any direct contact with the controller. The controller may not be sterilized or disinfected for a next use of the hard endoscope.

  • Patent number: 5454364
    Abstract: A medical instrument, particularly an endoscope, is provided with a device to guide the instrument within the intestine. The device is forwardly movable stepwise within the intestine with intermittent contact with the intestine wall. The device is so constructed to enable one to first push together on the instrument a part of the intestine surrounding the instrument, and then the device can be quickly pushed forward by taking advantage of the intestine's own inertia.

  • Patent number: 5447148
    Abstract: A coupling cartridge and end cap for protecting an endoscope from contamination during use. The coupling cartridge provides fluid communication between a pair of external fluid conduits and respective channels formed in an endoscope insertion tube, and between a biopsy channel port projecting from the cartridge and an additional insertion tube channel. In one embodiment, fluid flow through the external fluid conduits is controlled by an external fluid control unit that is electrically controlled by respective switches mounted on the control handle of the endoscope. In another embodiment, fluid flow through the external fluid conduits is controlled by a valve mechanism in the coupling cartridge that is controlled by either an actuator on the cartridge or an actuator on the control handle that is mechanically coupled to the valve mechanism. The coupling cartridge may be removed from endoscope after an endoscopic procedure for disposal or rigorous cleaning.

  • Patent number: 5419755
    Abstract: A weight bearing brace for a patient having femur or hip joint trouble has an upper socket removably attached to the periphery of an upper part of a thigh; a lower socket removably attached to the periphery of a lower part of the thigh; connectors for connecting the upper and lower sockets to each other, bearing patient's weight, and maintaining a required space between the upper and lower sockets; and a pelvis supporter disposed at an upper end of the upper socket, to substantially receive the weight of the upper half of the patient. The patient with the brace is able to move the hip joint. The pelvis supporter supports a lower part of the pelvis, to directly transfer the weight of the upper half of the patient from the upper socket to the lower socket, thereby avoiding the femur and hip joint from receiving the weight. The brace has a simple structure, is low cost, is easily attached to and detached from a thigh, and allows a knee joint with the brace to move, to smoothly carry out rehabilitation.
