This invention relates to the field of interbody fusion device technology, specifically a 3D-printed porous interbody fusion device, comprising a fusion device body, a first filling hole penetrating through the middle of the fusion device body, and a plurality of internal reinforcing ribs evenly distributed circumferentially on the inner wall of the first filling hole. Based on the biomimetic mechanical design concept of the biomedical engineering industry, this interbody fusion device can break through the limitations of traditional fixed-width fusion devices, and can accurately match the anatomical width of the intervertebral space of different patients without the need for manual cutting and modification during surgery. It can fully adapt to the individualized needs of various heights, weights and disease segments, and fundamentally avoid the risks of endplate damage, infection and anchoring structure damage caused by cutting. After implantation, the self-locking component can achieve immediate rigid locking, completely blocking the reverse rebound path of the adjustment block. Combined with the multi-occlusal tooth structure, it forms a stable mechanical anchor, eliminating postoperative micromovement, displacement and slippage problems, and greatly improving the overall stability of the fusion device in the early stage of implantation.

A spine internal fixing device with a fusion function comprises a pedicle screw, the pedicle screw comprises a screw body, a screw tail is arranged at the upper end of the screw body, a nut is connected to the screw tail through internal threads, the screw body and the screw tail are of a honeycomb structure simulating cancellous bone, and solid external threads are arranged on the outer surface of the screw body. According to the spinal internal fixation device with the fusion function, a full-assembly simulation cancellous bone honeycomb structure of a pedicle screw rod nut and a matched connecting piece is prepared by adopting a 3D printing technology, and meanwhile, solid structures of key stress parts such as an external thread tip threaded connection surface are reserved so as to guarantee early mechanical fixation strength; after the components are assembled, a continuous bone ingrowth channel is formed, so that the transformation of internal fixation of the spine from temporary mechanical support to permanent osseous fusion is realized, and various intervertebral, intervertebral, posterior lateral and transverse process bone grafting fusion steps in a traditional spine fusion operation can be omitted.

The embodiment of the present specification discloses a device driving control method, a surgical robot and a storage medium. The device driving control method comprises: determining a first calcification removal path according to a preoperative medical image of a target site; obtaining first position data of the device when the device moves in the target site; driving the device to reach a calcification area according to the first position data along the first calcification removal path; and driving the device to remove calcification in the calcification area after reaching the calcification area. The embodiment of the present specification can drive and control the device, thereby reducing the operation time and reducing the operation risk.

The invention discloses a guide-in method of an extended catheter, which comprises the following steps: S1, placing a catheter body in the circumferential direction of an interventional catheter, and enabling a first guide-in part and / or a second guide-in part to abut against the outer circumferential surface of the interventional catheter; s2, applying an acting force towards the direction of the interventional catheter to the catheter body, so that the first guide-in part and the second guide-in part are separated to form an opening through which the interventional catheter can penetrate; the intervention catheter enters the second inner cavity from the opening, and the first guide-in part abuts against the second guide-in part to close the opening; and S3, acting force in the axial direction of the pipe body is applied to the pipe body, so that the pipe body extends into the first inner cavity. The extension catheter can be arranged on the periphery of the interventional catheter in a sleeving mode from the opening in the peripheral side, then the extension catheter is pushed to the guiding catheter in the axial direction of the interventional catheter, the operation duration is shortened, and the operation risk is reduced.

The application provides an adjustable ureteral sheath, which comprises a supporting piece, a Y-shaped main body, a rotating mechanism, a guide sheath tube and an expansion mechanism; the Y-shaped main body comprises a first connecting port and a second connecting port, and the second connecting port is used for connecting a vacuum device; the expansion mechanism comprises an expander seat and an expander tube body, the expander seat is arranged on the first connecting port, and the supporting piece wraps the expander seat; the guide sheath tube wraps the expander tube body; the rotating mechanism comprises a rotating handle, a cam ring and a steel wire, the rotating handle is arranged on the cam ring, one end of the steel wire is arranged on the cam ring, the other end of the steel wire is arranged on the guide sheath tube, and the cam ring is arranged on the supporting piece. Through the rotating mechanism, the ureteral sheath can be adjusted and positioned, a stable channel is established, and an endoscope or a surgical instrument can conveniently enter and exit a lesion position.
