A Carpal Tunnel Release (CTR) surgical tool is disclosed. The CRT tool is useable to perform CTR surgically endoscopically through an incision in the patient, and includes dedicated optical components within the tool. The tool also includes wireless communication means to broadcast video images from the camera to an external display without the use of any cabling. The CTR tool is modular, thus allowing different portions of the tool to be replaced, including a blade tip assembly. The CTR tool is comprised of components manufactured of materials that can be cleaned and sterilized using an autoclave alone, which allows the tool to be more easily and cheaply used in subsequent surgeries, and in contexts that may lack the resources and support traditionally necessary for surgery. The CTR system may simply comprise of the tool (and its cheaper replacement parts), a monitor having wireless capability, and a simple autoclave.

A treatment instrument includes a probe including a treatment portion which treats a treatment target part by ultrasonic vibration, and a back portion provided on a side opposite to the treatment portion. The treatment instrument includes a hollow sheath which surrounds the probe, the sheath having a cutout made to expose the treatment portion. The treatment instrument includes protrusion which is provided in the sheath to cover the back portion on a side opposite to the cutout and which has dimensions smaller than the dimensions of the probe in a direction that intersects with a central axis of the probe.

A connector comprises an upper surface finger-resting portion that extends in the longitudinal axial direction on the outer periphery of the gripping portion, and on which the first finger is placed, a lower surface finger-resting portion on which the second finger or the third finger is rested when the connector is gripped by placing the first finger on the upper surface finger-resting portion, and a guide protrusion portion that is arranged on the same straight line as the upper surface finger-resting portion in the longitudinal axial direction and determines the position to be inserted, in which the connector is directly fitted into the receiving-side connector by directing the finger tip of the first finger that is placed on the upper surface finger-resting portion to the guide groove of the receiving-side connector and inserting the connector.

The disclosure extends to systems and methods for reducing the area of an image sensor by employing bi-directional pads used for both image data issuance and configuration command reception and internal supply voltage generation, for reducing the number of conductors in an endoscope system.

To prevent, in a medical device that includes a tip-side device to be brought into contact with or inserted into an object to be observed and a root end-side device connected to the tip-side device, the leakage of radiation noise generated in the root end-side device to the outside and the entry of disturbance noise into the root end-side device.

A connection structure includes: a plug provided at a root end of the tip-side device; and a receptacle provided in the root end-side device and configured to hold the plug by insertion. At least one of the plug and the receptacle contains an electrically non-conductive magnetic material in a portion crossing an opening formed in the outer casing in a state where the plug is inserted in the receptacle.

A first connector for a medical instrument has one or more first channels extending through a first surface, and terminating at respective ends. A second connector has opposing second channels for coupling with the first channels. A first power transfer element is mounted on the first connector, and defines a first cross-sectional shape that encompasses at least one of the one or more first channels and has a first central axis extending through the first surface. A second power transfer element on the second connector defines a second cross-sectional shape that encompasses at least one of the one or more second channels and has a second central axis extending through the second surface. The first power transfer element may instead be on a side surface of the first connector, and may couple with a paired element on a receptacle or extension of the second connector.

The disclosed technology is directed to an endoscopic apparatus comprises an endoscope having a cable connected to an electronic circuit part of the endoscope. The cable includes an elongated covering and an elongated component configured to be concentrically engaged with the elongated covering. A securing member is used to bind and to secure the elongated covering and the elongated component to one another. The elongated covering includes at least one recess formed on an outer circumferential area of the elongated covering on which the securing member binds and secures the elongated covering. The securing member has a portion that sinks in the at least one recess and secures the elongated covering and the elongated component that is exposed through the at least one recess.

A cable connection structure includes: a substrate that includes: an opening; and a core wire connection electrode that is arranged on one of a principle surface and an inner layer across the opening; a cable that is arranged on a principle surface side of the substrate and includes a core wire that is electrically connected to the core wire connection electrode, the core wire connection electrode being extended so as to be separated from the substrate, the core wire connection electrode being connected to the core wire.

To provide a substrate for a medical device and a medical device in which the reference potential of a patient circuit can be stabilized, the noise between the patient circuit and a ground-side circuit can be reduced, and the insulation distance between the patient circuit and the ground-side circuit can be sufficiently ensured without using a large-sized electronic component.

A patient circuit that is a circuit on the side of being brought into contact with or inserted into a subject, a ground-side circuit that is a circuit provided on the side of performing processing on a signal transmitted from the side of being brought into contact with or inserted into the subject and protectively grounded, an insulating layer provided between the patient circuit and the ground-side circuit and providing insulation between the patient circuit and the ground-side circuit, and an isolated circuit provided apart from the patient circuit and the ground-side circuit on the surface of the insulating layer and having a different reference potential from the patient circuit and the ground-side circuit are included.

An endoscope includes: a connector portion for electrically coupling to an external connector. The connector portion includes: a base portion having a tubular shape; and a tubular sleeve portion extending from the base portion, at least a part of an end portion of the sleeve portion being provided with a cutout portion. When a water-resistant cap is installed at the connector portion, the endoscope takes any state of a first state where an abutting portion of the water-resistant cap configured to abut on the sleeve portion abuts on the sleeve portion on a side of the base portion with respect to the cutout portion to hold an airtightness between the water-resistant cap and the connector portion, and a second state where the abutting portion abuts on or faces the sleeve portion including the cutout portion to make non-airtight between the water-resistant cap and the connector portion.
