Abstract: The present disclosure relates to a vertebral balloon dilation system, comprising a rigid pushing tube (2), a balloon (1) made of membrane material and fixedly connected with a sealing head (11), a sleeve tube (3) sleeved on the pushing tube (2) and the balloon (1), and a liner core (4) slidably inserted into the pushing tube (2). When the vertebral balloon dilation system is operated, the sleeve tube (3) slides axially towards the proximal end of the pushing tube (2), and the balloon (1) is exposed. According to the present disclosure, the balloon (1) can be fed to the center or to the opposite side of the vertebral body simply by puncturing at only one side without drilling out a cavity in advance, thus simplifying surgical procedures, shortening duration of surgery, reducing the incidence of complications, alleviating the pain of patients and reducing the economic burden of patients.

Abstract: A bone idler implanting system comprises a bag (1) and a delivery device (2). A distal end of the bag (1) is fixedly connected to a sealing head (11); the sealing head is closed at its distal end and has a blind hole (111) at its proximal end, and the blind hole (11) has an opening towards the interior of the bag (1). The bag (1) has micro-pores (12). The delivery device (2) comprises a liner core (23), a delivery tube (21), and a sleeve tube (22). The delivery tube (21) is a rigid tube, and a distal end of the delivery tube (21) is detachably connected to a. proximal end of the bag (1). When the delivery device (2) is operated, the sleeve tube (22) slides axially towards the proximal end of the conveying tube (21), and the bag (1) is exposed.

Abstract: A cryoablation system has a gas source which provides a working nitrogen gas at room temperature and at a constant set pressure, a liquid generator which is coupled to the gas source to receive the working gas, and which then generates a working cryogen fluid, and a catheter coupled to the liquid generator for receiving the working cryogen, the catheter having a distal section having a freezing element which delivers the working cryogen to a treatment location, the catheter also having a balloon positioned adjacent the distal section.

Abstract: A steerable cannula for delivering bone filler comprises a delivery pipe (10), a delivery handle (30) fixedly connected to the proximal end of the delivery pipe, a sheath-core (20) slidably inserted into the delivery pipe and a sheath-core handle (40) fixedly connected to the proximal end of the sheath-core. Distal portion of the delivery pipe is a flexible pipe (11) and proximal portion thereof is a rigid pipe (12). The sheath-core has a cavity. Distal portion of the sheath-core is a flexible segment (21) and the proximal portion thereof is a rigid segment (23). A pull thread is provided in the cavity of the sheath-core, wherein distal end of the pull thread is fixedly connected to the distal end of the flexible segment of the sheath-core and proximal end thereof is connected to a drawing means arranged on the sheath-core handle.

Abstract: An absorbable blood vessel stent (100) 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 (2, 3). The support bar or the connection bar (2, 3) comprises a straight line section, a U-shaped section, or an S-shaped section, and at least one through groove or through hole (5, 6) is provided on at least one support bar. Because of the special structure of the blood vessel stent (100), 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.
