A stent connection tube assembly for a catheter pump and a catheter pump. The catheter pump comprises a drive shaft, a catheter, and a pump head. A distal end of the catheter is connected to a proximal end of the stent connection tube assembly, and a distal end of the stent connection tube assembly is connected to a proximal end of the pump head. The stent connection tube assembly for the catheter pump comprises a stent connection tube and a stent proximal support member. An accommodating cavity having openings at both ends is provided within the stent connection tube, and the stent connection tube is provided with a first limiting structure. The stent proximal support member is sleeved within the accommodating cavity and is configured to support rotation of the drive shaft, and the drive shaft is configured to drive rotation of an impeller inside the pump head. The stent proximal support member is provided with a second limiting structure. The first limiting structure can cooperate with the second limiting structure to restrict axial movement and circumferential rotation of the stent proximal support member, thereby providing stable support for the drive shaft.

The invention discloses a reflux valve stent which comprises a stent main body which is in a grid shape and comprises a plurality of grid units which are sequentially arranged in the axial direction of the stent main body; the multiple release pieces are connected to the grid units located at the outflow end and are arranged at intervals; the positioning anchoring pieces are connected to the grid units located at the outflow end, and each positioning anchoring piece is connected between every two adjacent releasing pieces; the plurality of positioning anchoring parts are folded towards the outflow end and are accommodated in the first accommodating cavity after being compressed with the plurality of releasing parts, and the stent main body is accommodated in the second accommodating cavity after being compressed, so that the valve stent is in a compressed state; when the multiple positioning anchoring pieces are released from the first containing cavity, the multiple positioning anchoring pieces are turned over by a certain angle towards the inflow end, and when the support body is released from the second containing cavity, clamping gaps are formed between the positioning anchoring pieces and the support body. The reflux valve stent provided by the invention is convenient to operate, and the surgical precision and the structural stability are improved.

The present invention relates to an endoluminal stent and an endoluminal stent system, with the endoluminal stent being delivered to a site at which it is to be implanted by means of a delivery device comprising a sheath for receiving the endoluminal stent. The endoluminal stent comprises a hollow tube body portion, a connection portion and a flange portion, wherein the tube body portion is connected to one end of the connection portion, the flange portion has a connection end and a suspended end opposite one another, with the connection end being connected to the other end of the connection portion in a turning connection, and the suspended end being suspended, the flange portion comprising a flange section bare wave ring made of an elastic material; the suspended end is located at a distal side of the connection end when the endoluminal stent is in a natural state; the suspended end is located at a proximal side of the connection end when the endoluminal stent is received in the sheath; and after the flange portion is released from the sheath, the flange portion automatically turns over, and the suspended end moves from the proximal side of the connection end to the distal side of the connection end. The endoluminal stent of the present invention can enhance the anchoring force thereof.

The utility model relates to the technical field of medical instruments and equipment, and discloses a visual intracavitary built-in esophageal stent releaser which comprises an outer tube and an inner tube, the inner tube penetrates through the outer tube, one end of the inner tube is connected with a traction head, the other end of the inner tube is connected with an inner tube handle, one end of the outer tube away from the traction head is connected with an outer tube handle, and the outer tube handle is connected with the traction head. An optical fiber is arranged in the inner tube, one end of the optical fiber extends to penetrate through the traction head, and the other end of the optical fiber extends into the inner tube handle; the device has the effects of providing illumination for an affected part and obtaining the state of the affected part in real time, and also has the effects of preventing the outer tube from driving the release bracket to move when the outer tube moves relative to the release bracket and ensuring that the release bracket is released at the affected part.

The dental implant packaging bottle comprises a bottle tube, a cap and a support, a containing cavity is formed in the bottle tube, and an opening communicated with the containing cavity is formed in one end of the bottle tube; the cap can be connected with the opening to close the accommodating cavity; the support is connected with the cap and contained in the containing cavity after the cap is connected with the opening, a fixing block used for fixing the dental implant is installed on the support, and the dental implant is separated from the fixing block after being connected with the nail extractor. According to the dental implant packaging bottle, the support is connected with the cap, the fixing block used for fixing the dental implant is installed on the support, and the dental implant is separated from the fixing block after being connected with the nail extractor.
