The present invention relates to a device for the non-surgical clipping of aneurysms. The invention also includes methods of use to treat aneurysms, including intracranial aneurysms. The aneurysm is clipped by positioning a wire comprising a shape memory alloy, pre-set to a mutually twisted conformation, on opposite sides of the neck of the aneurysm and causing the wires to twist around each other. Thus, the aneurysm neck is substantially closed. The resulting thrombosis in the aneurysm further excludes the aneurysm from blood flow and pressure.

The invention provides a medical surgical forceps, which belongs to the related technical field of medical instruments, and solves the technical problems that the existing surgical forceps cannot clamp and clamp irregular affected parts well. The medical surgical forceps includes a first forceps bar and a second forceps bar, the upper and lower sides of the first forceps bar are fixed with hinged blocks, and the upper and lower sides of the second pincers bar are detachably fixed with hinged shafts, and the hinged shafts are rotatable It is arranged on the hinge block, one end of the second tong bar is fixed with a clamping tong head, and an auxiliary tong mechanism is arranged inside the first tong bar. The present invention adopts the cooperation of the clamping pliers head and the auxiliary pliers mechanism, which can clamp and clamp the affected area. At the same time, the auxiliary pliers mechanism adopts the cooperation of the first pliers head and the second pliers head to provide the clamping direction of the clamping pliers head and the auxiliary pliers mechanism. The perpendicular clamping can better clamp and clamp the irregular affected area to avoid secondary damage; through the cooperation of the connecting screw and the screw hole, the opening angle of the first clamp head and the second clamp head can be adjusted, and Self-locking after clamping to avoid loosening.

A surgical instrument includes a shaft defining an axis, an end effector coupled to a distal portion thereof, a fixed handle coupled to a proximal portion thereof, a drive bar, a movable handle, and a linkage. The drive bar is disposed within the shaft and operably coupled to the end effector. The movable handle is movable relative to the fixed handle between open and closed positions and is coupled to the drive bar via a first pin on the axis. The linkage includes a first end portion coupled to the movable handle via a second pin and a second end portion coupled to the shaft via a third pin on the axis. In the closed position of the movable handle, the second pin is disposed in a near-over-center position relative to the axis to reduce a force necessary to maintain the movable handle in the closed position.

A surgical clip for simultaneously cutting a blood vessel and controlling bleeding, includes two legs, each including a flat surface and a cutting surface, and a curved section configured to join the two legs. An applicator for installing a surgical clip that simultaneously divides a blood vessel and controls bleeding, includes two jaws that simultaneously hold two surgical clips, and two handles that cause the two jaws to exert a deforming force on the two surgical clips.

A flexible multi-joint surgical micro-instrument for robot-assisted minimally invasive surgery, in order to solve the problem that the existing minimally invasive surgical robot surgery micro-instrument cannot be positioned, moved and other operations in the patient's body relying on the surgical micro-instrument itself. The transmission mechanism is installed on the drive box, and the six connection holes correspond to the first installation hole, the second installation hole, the third installation hole, the fourth installation hole, the fifth installation hole and the sixth installation hole respectively. A transmission part is installed in the hole, and the first bending transmission mechanism, the second bending transmission mechanism, the third bending transmission mechanism, the fourth bending transmission mechanism, the surgical forceps opening and closing transmission mechanism and the surgical forceps rotation transmission mechanism are respectively connected with the corresponding transmission parts , the lower end of each transmission part is connected with the micro-drive motor, the rear end of the catheter is connected with the catheter fixing part, the front end of the catheter is connected with the flexible bending arm mechanism, and the front end of the flexible bending arm mechanism is connected with the surgical forceps mechanism. The invention is used for abdominal surgery.
