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.

The tool realizes long-distance driving by adopting the wire rope, thereby eliminating return differences and guaranteeing reliable driving.

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.

Surgical wire closure devices, which in some embodiments may be incorporated onto other surgical devices such as surgical pliers, comprising an elongate arm having a hook at one end and a shaft at the other end, wherein the axis of the arm is angled in relation to the axis of the shaft, and wherein the shaft is rotatably connected to a handle. The hook is inserted under a first node of surgical wire during approximation, followed by rotation of the hook about the axis of the shaft, which is accomplished by a slight pivoting motion of the surgeon's hand about the wrist as he or she grasps the handle.

The invention relates to the field of medical apparatus and instruments, and discloses a special surgical wire retractor for orthopedic surgery. The special surgical wire retractor for orthopedic surgery comprises a grab handle, wherein the front surface and side surfaces of one end of the grab handle are fixedly connected with fixing plates separately; each fixing plate is movably connected witha vertical rod in a sleeving manner; the bottom end of each vertical rod is fixedly connected with a fixing baffle; the bottom end of a side surface of each vertical rod is fixedly connected with a clamping device positioned above the corresponding fixing plate; the middle of the top end of the grab handle is fixedly connected with a supporting plate; and the supporting plate is fixedly connectedwith a fixing shaft. According to the special surgical wire retractor for orthopedic surgery, by movement of the vertical rods in the chutes and slide ways of the fixing plates, retractable rods on two sides rotate to suitable angles, a wire retractor body connected with a middle retractable rod hooks the middle of an opening of a patient, the other two sides hook skin and flesh of two sides, thus, surgical field is open, and meanwhile, by cooperation of wire retractor bodies on the two sides, the circumstance that the skin and flesh of the patient are torn off is avoided when the skin and flesh of the patient are hooked by the middle wire retractor body.

A device for sealing damaged and defective vessels utilizes a surgical wire or similar appliance positioned and housed within a protective sheath, such as a catheter or needle. Stable thrombin and non-thrombin based solutions, gels, or biological glues are then used to coat the tip of a surgical appliance, such as surgical wires and trocars, with concentrations sufficient to cause clotting. The protective sheath around the wire and a one way valve provides a barrier which prevents clotting material to insinuate itself into healthy tissue. The protective catheter containing the wire is then inserted into the body of the patient and directed to the damaged site. The wire is then partially extended out of the sheath to allow the clotting material to be applied and deposited onto the damaged vessel, thereafter the wire and sheath are safely withdrawn from the body of the patient.

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 present invention relates to a device for placing, in the His bundle, a pacemaker lead tip having passed through the coronary sinus and, more particularly, to a device for placing, in the His bundle, a pacemaker lead tip having passed through the coronary sinus, as one way to more effectively deliver electrical stimulation in treating patients with cardiac arrhythmia by using a pacemaker. Thedevice for placing, in the His bundle, a pacemaker lead tip having passed through the coronary sinus comprises: a surgical wire; a capture catheter in which an electrocardiogram sensor is provided todetermine the location of the His bundle in the interventricular septum, and which captures the surgical wire located in the right ventricle; and a pacemaker lead which has a through hole for passingthe surgical wire therethrough such that the tip of the pacemaker lead is inserted into the His bundle along the surgical wire.
