Embodiment 1

[0059] refer to Figure 1-12 The invention provides a conveying device, which comprises a shell, an outer tube 60, a pushing tube 50, a front slider 20, a rear slider 30, a transmission mechanism and a driving mechanism; The transmission mechanism comprises a first transmission screw 42 and a second transmission screw 44 which are coaxially and rotatably installed in the housing, wherein the first transmission screw 42 is connected with the front slider 20 in a screw manner, and the second transmission screw 44 is connected with the rear slider 30 in a screw manner; The driving mechanism is connected with the first driving screw 42 and the second driving screw 44 through a transmission assembly, and drives them to rotate; The screw directions of the threads on the first drive screw 42 and the second drive screw 44 are opposite, and the first drive screw 42 and the second drive screw 44 drive the front slide block 20 and the rear slide block 30 to move relatively or back to each oth...

Embodiment 2

[0085] refer to Figure 13 This embodiment is an adjustment based on Embodiment 1.

[0086] In this embodiment, the auxiliary transmission gear is omitted, and the intermediate transmission gear 170 partially extends out of the housing (130', 120') and engages with the teeth of the inner ring of the handwheel 70' to realize transmission connection.

[0087] Other structures of the conveying device in this embodiment can refer to the description in Embodiment 1, and are not described here.

Embodiment 3

[0089] refer to Figure 14-16 This embodiment is an adjustment based on Embodiment 1.

[0090] In this embodiment, further, a locking and unlocking mechanism is arranged between the handwheel 70' and the housing, which is used to limit the rotation of the handwheel 70'. On the one hand, when not in use, the handwheel can be locked to prevent accidental contact from rotating.

Abstract

The invention provides a conveying device, which includes a housing, an outer tube, a push tube, a front slider, a rear slider, a transmission mechanism, and a drive mechanism; screw, the second transmission screw, the first transmission screw is spirally connected with the front slider, the second transmission screw is spirally connected with the rear slider; the driving mechanism drives the first transmission screw, and the second transmission screw is connected; the first transmission screw, the second The helical direction of the screw thread on the transmission screw is opposite; the rotation of the first transmission screw and the second transmission screw drives the front slider to move relative to each other or opposite to each other; One end protrudes from the casing; one end of the push tube is fixedly connected to the rear slider, and the other end is movably installed on the front slider, and the push tube is coaxially arranged with the outer tube; when the rear slider moves relative to the front slider, it drives the push tube Said protrudes into the outer tube, and pushes the device to be delivered out of the outer tube.

Description

Technical field [0001] The invention relates to the technical field of mechanical structure design, in particular to a conveying device. technical background [0002] Vascular diseases have become one of the global problems threatening human health. With the aging of population and the change of diet structure, its incidence is increasing day by day. Percutaneous interventional technique is a rapidly developing method for the treatment of vascular diseases in recent years, and its application field is more and more extensive. [0003] Common vascular diseases include human heart, peripheral blood vessels of arteries and veins and nerve vessels. Catheter interventional therapy is used to transport instruments to targeted lesion sites. At present, when catheter intervention is used to prevent these instruments from entering the human heart and arteriovenous vessels, due to the complex anatomical structure of the human heart and arteriovenous vessels, to ensure that the instruments ...
