A tool for replacing an escalator drive shaft comprises a first tool and a second tool. One side of the first tool is adapted to be assembled on an original shaft adapter, and the other side of the first tool is adapted to be assembled on a new shaft adapter. The second tool is adapted to be assembled on the first tool. A central axis of the first tool coincides with a central axis of the original shaft adapter, a central axis of the second tool coincides with the central axis of the first tool, and the central axis of the first tool coincides with a central axis of the new shaft adapter. A positioning reference of the original drive shaft is accurately transferred to the new drive shaft by the first and second tools, so that the new drive shaft may be accurately assembled to the position of the original drive shaft with respect to the truss after replacement.

A marker for use in the lung of patients for marking the position of a lesion in the lung, wherein the marker comprises a self-expandable structure capable of self-expanding when released from a constricting device so as to implement marking function. Because the marker for use in the lung of a patient employs the self-expandable structure, when the position of a lesion is detected during a lung examination, the marker can be delivered to the position of the lesion via a catheter or a delivering device and substantively pressed and fixed by the lung when expanded at the lesion positions; as such, the lesion position can be located quickly by a surgeon during a surgery, the surgery time is shortened, the area of resection is reduced, and the post-surgery quality of life is improved for a patient.

Marker for use in the lung of patients

The present invention provides an aortic arch intraoperative stent, wherein the aortic arch intraoperative stent comprising a main body () and one to three branches (), The aortic arch intraoperative stent connects several circular waveform rings together via a cover membrane () to form the main body () and the branches (), wherein each circular waveform ring comprises a circular elastic wire formed through head-to-tail connection. In addition, the present invention also provides a manufacturing method for the aortic arch intraoperative stent, comprising the following steps of: providing a cover membrane mandrel (); making an inner membrane; assembling circular waveform rings; making an outer membrane; suturing a proximal fabric (); and suturing a distal fabric (). The aortic arch intraoperative stent can automatically adapt to the vascular structure near the aortic arch of different patients, and the main body () in the aortic arch intraoperative stent maintains a sufficient radial support for the branches, thereby ensuring that the branches on the aortic arch intraoperative stent may safely enter branch vessels during surgery, and preventing the branches from slipping out of the corresponding branch vessels during and after surgery at the same time.

A braided self-expandable endoluminal stent comprises a tubular grid formed by connection of a plurality of wave bends in the circumferential direction. Each of the wave bands comprises a plurality of crests and troughs of an elastic wire in the axial direction, and is respectively connected with another wave band. On two sides of each of the wave bands, there is a wave band abutted thereto side by side. There is at least one cross-linking point between every two wave bands abutted side by side. Each of the cross-linking points is formed by intersecting one trough on one of the wave bands abutted side by side with one corresponding crest on the other wave band, and at least one part of the cross-linking points are fixed cross-linking points. Each of the wave bands is further staggered and overlapped with at least another wave band, and a plurality of crossing points () are formed between the wave bands which are staggered and overlapped with each other. Each of the wave bands, together with at least another wave band, forms a group of parallel wave bands. As the wave bands in this group are similar in wave shape and in parallel to each other, no cross-linking points or crossing points () will be formed between the parallel wave bands.

A bifurcated stem graft () comprises a body () and a side branch () that forms an acute angle with the body (). The side branch () comprises a covering film () and a first bare stent () only disposed on the covering film (). Part of the first bare stent () is positioned adjacent a boundary line () of the body () and the covering film () and is located in a vertex angle area () of the acute angle. Due to the fact that part of the first bare stem () is attached to the vertex angle area (), after the stem () is released, the self-expanded part of the first bare stent () enables the vertex angle area () of the side branch () to be effectively supported, the covering film is not prone to shrinkage, and a leading wire can enter easily. Meanwhile, a special bare stent attached to the vertex angle area () does not need to be additionally disposed on the first bare stent (), and thus the technology for preparing the bare stem is simplified; furthermore, the first bare stent () is only disposed on the side branch () and does not need to span the connecting part of the body () and the side branch (), and thus the waveform can be shaped easily.

Fork-type covered stent

The present invention relates to a thoracic aortic covered stent (), comprising a bare stent segment () and a covered stent segment (). The bare stent segment () comprises a bare wave-shaped ring (); the covered stent segment () has a lesser curvature side region (), a greater curvature side region (), and two opposite intermediate regions () located between the lesser curvature side region () and the greater curvature side region () respectively; and the covered stent segment () comprises a first proximal wave-shaped ring (). The stent () further comprises a first connecting member (), a first side connecting member () and a second side connecting member () all connected to the bare wave-shaped ring () and the first proximal wave-shaped ring (), wherein the first connecting member () is arranged in the lesser curvature side region (), and the first side connecting member () and the second side connecting member () are arranged in the two intermediate regions () respectively. The stent () when located near the lesser curvature side () with a relatively small radius of curvature has a connecting assembly rigidly connecting the bare stent segment () and the covered stent segment (), and through the constraints thereof, the bare stent segment () can be effectively prevented from overturning towards the vessel wall during the release process, so that the proximal end of the covered stent segment () is securely apposed to the wall, thereby avoiding the 'turnover' effect.

Thoracic aortic covered stent

An absorbable blood vessel stent () has a near end and a far end. A tubular patterned structure is formed between the near end and the far end. The patterned structure comprises a plurality of support bars and connection bars (). The support bar or the connection bar () comprises a straight line section, a U-shaped section, or an S-shaped section, and at least one through groove or through hole () is provided on at least one support bar. Because of the special structure of the blood vessel stent (), the performance of an iron blood vessel stent can be improved, and blood vessel stents made of other absorbable materials can be decomposed more rapidly.
