Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] Such as Figure 1-Figure 2 As shown, a catheter injection advance and retreat synchronizer includes a frame 1, and at least one set of driving mechanisms for driving the catheter 2 to advance and retreat are arranged in the frame 1, and the driving mechanism includes two for clamping the catheter. 2, a circular rotating member 3 that can rotate relative to each other, and a power mechanism for driving the rotating member 3 to rotate is also arranged in the frame 1.

[0020] The circular rotating member 3 is provided with a groove along its circumference, and a rubber ring is arranged in the groove. In this embodiment, the circular rotating member 3 is a gear, and the driving mechanism includes two meshing gears arranged up and down. By passing the conduit 2 between the grooves of the two gears, during the rotation of the gears, the friction force generated by ...

Abstract

The invention discloses a catheter injection advancing and retreating synchronizer. The synchronizer comprises a rack, at least one set of driving mechanism used for driving a synchronizer to advance and retreat is arranged in the rack, and each driving mechanism comprises two circular rotating parts which are used for clamping the synchronizer and can rotate relatively. A power mechanism used for driving the rotating parts to rotate is further arranged in the rack. The catheter is clamped by the least one set of driving mechanism, the catheter is driven to advance and retreat at a constant speed through rotation of the driving mechanism, and an injector is pushed by a push rod synchronously moving with the catheter to perform synchronous glue injection, so that the catheter advances and retreats at a constant speed, and meanwhile, uniform glue injection is ensured when the catheter retreats.

Description

technical field [0001] The invention relates to a catheter injection advance and retreat synchronizer, which belongs to the technical field of medical equipment. Background technique [0002] In many operations, it is necessary to intubate the patient, and it is usually required to maintain a constant speed during the insertion and withdrawal of the catheter. At present, the existing methods of inserting and pulling out the catheter are usually manually operated, which is difficult to ensure the real uniform movement of the catheter, which will affect the operation to a certain extent. [0003] In blood vessel bonding surgery, it is not only required to insert and pull out the catheter at a uniform speed, but also to inject glue evenly while the catheter is being pulled out, so as to ensure the best surgical effect. Apply glue evenly. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a catheter injection advance ...
