An optical coherence tomography probe and laser combination device configured for real-time z-directional guidance of the incisional depth of a surgical procedure. It can be used alone or placed within the working channel of an endoscope. The device includes an OCT single mode fiber, and a laser fiber or laser hollow waveguide or electrical surgical wire positioned adjacent to the OCT single mode fiber. The single mode fiber is configured to move laterally when activated by an actuator to scan light data reflected from a sample that is positioned in front of a distal end of the device. The light data can be processed to generate a B-scan image. The device can collect data in real-time during lasing, or immediately prior to and following the cutting. The surgical tool, when coupled to a processor, can deactivate when the B-scan image identifies that the incision is within a predefined tolerance.

A cable clamp includes a housing having two substantially parallel and co-planar channels therethrough. At least one restraining member is disposed within the housing between the two channels, also substantially parallel and co-planar therewith. A surgical cable is passed through the first channel, around a bone or other structure, and through the second channel. The restraining member may then be actuated to impinge against the surgical wire or cable, simultaneously constraining the surgical wire or cable within both channels between the restraining member (an inner wall) and the housing (an outer wall). For example, the restraining member may be an expansion member that, when expanded as by driving a wedge between two restraining arms, reduces the size of the channels such that the surgical wire or cable can no longer pass freely therethrough.

A method and device for improving the placement of a second guide wire in relation to a first guide wire. A body having a first guide wire channel extends from a proximal end to a distal end. The distal end includes a needle-like tip arranged to receive a first guide wire from the first guide wire channel. The body further includes at least one parallel guide wire conduit in close proximity and substantially parallel to the channel. An elongated slot, with a wide opening on the distal end, narrows at the proximal end with a terminus exiting the body in close proximity to the needle-like tip. A second guide wire can be selectively inserted in either the at least one parallel conduit or in the slot to arrange the second guide wire in close and parallel proximity to, or in close and intersecting the trajectory of, the first guide wire.

A wire driver for driving a wire or pin into living tissue. A plural bar linkage that includes a lever is actuated to drive the components that selectively grasp the wire from a release state to a grasping state.

The invention is directed to a surgical device which is externally used as aiming device that permits accurate placement of surgical wire to mend a supracondylar fracture. The device of the invention decreases operative time, risks of the re-dislocation through continuous manipulation, radiology exposure for both the patient and operation room staff, and to decreases anesthesia duration. It is also directed to surgical use of the device for repair of a supracondylar fracture and to methods for making it.

The invention discloses a device for fixing the position of an organ in an operation, which comprises a vertically arranged connecting column, one end of which is provided with a connecting structure; the other end of the connecting column is provided with a lifting structure; the lifting structure includes a first connecting plate, a first connecting seat , the second connecting seat and the first screw rod, the first screw rod is arranged vertically, and the first screw rod is used for detachably connecting the surgical wire at one end close to the operating bed; the first connecting plate is arranged horizontally, and one end of the first connecting plate is connected to the connecting column One end away from the connection structure; the first screw rod passes through the first connection and is threadedly connected to the first connection seat and the second connection seat respectively, the first connection seat is located on the side of the first connection plate facing the connection structure, and the second connection seat is located on the second connection seat. A side of the connection plate away from the connection structure. The invention proposes a technical solution, and the medical staff only need to turn the first screw rod to adjust the height of the viscera to ensure the operation field of view and avoid the waste of manpower.

The invention relates to the technical field of catgut, and discloses a surgical wire fixing device for nursing care in an operating room. A catgut is provided, a control airbag is fixedly installed inside the control mechanism, a conducting trachea is fixedly connected to the bottom of the control airbag, a hollow spring is fixedly connected to the bottom of the conducting trachea, and the right side of the hollow spring is fixed A transmission rod is connected, a control wheel is rotatably connected to the right side of the transmission rod, a detection processing mechanism is arranged above the control mechanism, and an air extraction mechanism is arranged inside the detection processing mechanism. The operating wire fixing device for nursing in the operating room is used in cooperation with the catgut, the control spine rod and the detection and processing mechanism, so as to achieve the effect of preventing the catgut from gradually drying and causing medical accidents when clamping the catgut.

A method for attaching an elongated object to bone, the method comprising:forming a hole in the bone;positioning a loop of the elongated object in the hole;advancing a surgical wire into the bone so that the surgical wire is directed toward a location within the interior of the loop; andsevering the surgical wire intermediate its length so as to create a distal portion and a remainder portion and, if the distal portion of the surgical wire does not extend through the loop, further advancing the distal portion of the surgical wire so that it extends through the loop.
