Embodiment 1

[0028] Example 1, please refer to Figure 1-Figure 3 As shown, this embodiment provides a catheter driving mechanism for glaucoma sticky tubules, including a housing 1 and a driving wheel 2 and a driven wheel 3 arranged inside the housing 1. The driving wheel 2 and the driven wheel 3 can interact with each other. Fits to grip the catheter.

[0029] When in use, the driving wheel 2 and the driven wheel 3 can cooperate with each other to clamp the catheter between the driving wheel 2 and the driven wheel 3 . When the catheter is delivered, the driving wheel 2 rotates and drives the driven wheel 3 to rotate together. Since the catheter is clamped between the driving wheel 2 and the driven wheel 3, it can move axially with the rotation of the driving wheel 2 and the driven wheel 3 , to achieve catheter delivery.

[0030] Further, in this embodiment, the drive wheel 2 is fixedly connected to the inner wall of the casing 1 through the bearing frame 4 . The driving shaft can not s...

Abstract

The invention provides a catheter driving mechanism for glaucoma mucoplasty, which relates to the technical field of medical devices. The mechanism comprises a housing and a driving wheel arranged inside the housing, driven wheels, swing assemblies and gearboxes. The swing assembly is arranged on the driven wheel for axially moving the driven wheel, and the gearbox has an input shaft, a first output shaft and a second output shaft, wherein the first output shaft is connected with the driving wheel, the second output shaft is connected with the swing assembly, and the input shaft protrudes to the outside of the housing. When in use, the driving wheel and the driven wheel can cooperate with each other to sandwich the conduit between the driving wheel and the driven wheel. When the catheter is delivered, the driving wheel rotates and drives the driven wheel to rotate together. As the catheter is clamped between the driving wheel and the driven wheel, the catheter can move along the axialdirection with the rotation of the driving wheel and the driven wheel, thereby realizing the delivery of the catheter.

Description

technical field [0001] The invention relates to the field of medical appliances, in particular to a catheter driving mechanism for glaucoma sticky tubule angioplasty. Background technique [0002] Glaucoma viscocanalectomy is based on external Schlemm canal (sclera venous sinus) incision, laser-guided light guide fiber enters Schlemm canal, 360° Schlemm canal incision or dilated plastic surgery, so as to enhance the physiology of the trabecular meshwork Sexual drainage. Catheter push for glaucoma sticky tubuloplasty: The doctor inserts the microcatheter into the stump of Schlemm's canal and runs along the Schlemm's canal until it passes through the stump on the opposite side. If resistance is encountered during the advancement of the catheter, retract the catheter and repeat the forward movement. If the catheter vagus enters the sclera, pressurize the tip of the catheter on the side of the sclera at the starting point of the catheter vagus to make it return to the Schlemm'...
