Problems solved by technology

However, due to the one-piece fixed structure of the support rod, it is very difficult to install and release the two ends of the monofilament on the support rod, and it is easy to bring out the half-released monofilament during the process of pulling out the support rod, resulting in failure of the operation

Embodiment Construction

[0013] like figure 1 As shown, the vascular dilator implantation tool with a locking mechanism of the present invention includes a handle 1 and a push rod 2 inserted in the handle 1 to move axially. The rear end of the push rod 2 is provided with a pressure plate 3 , The handle 1 is a columnar structure, and the pressing plate 3 and the push rod 2 can slide axially in the handle 1. The push rod 2 is covered with a spiral jacket 4, and the spiral jacket 4 is a helical structure formed by spirally coiling a special-shaped monofilament. The material of the spiral jacket 4 is made of elastic plastic, stainless steel, etc. The section of the special-shaped monofilament is circular, and the upper and lower sides of the special-shaped monofilament are symmetrically provided with an upper clamping helix 5 and a lower clamping helix 6, and the upper clamping helix 5 and the lower clamping helix 6 are cross-sectional shapes It is a triangular helical rib, and the axes of the upper clam...

Abstract

The invention relates to a medical instrument, in particular to a vascular dilator implanting tool with a locking mechanism, comprising a handle and a push rod inserted into the handle and that can axially move. The rear end of the push rod is provided with a press plate and sleeved with a spiral sleeve, the spiral sleeve is made by spiraling a deformed single wire, the upper and lower ends of the section of the deformed single wire are symmetrically provided with an upper clamping thread and a lower clamping thread, one end of the deformed single wire is fixedly connected to the front end of the push rod, and the other end of the deformed single wire is fixedly connected to the handle. This tool is simple in structure, convenient to operate and widely applicable.

Description

technical field [0001] The invention relates to a medical device, in particular to a blood vessel dilator implantation tool with a locking mechanism. Background technique [0002] At present, the commonly used cardiovascular dilation surgery is mainly to install stents or balloons. Since the cardiovascular pipeline is relatively thin, the operation during the operation is very troublesome. It takes a lot of time and energy to install and adjust the position of the stent, which brings difficulty and risk to the operation. Chinese patent 2010202319042 discloses a "cardiovascular dilation device" in which the mesh stent is installed in a guide tube in advance, and a stylet is also installed in the guide tube. During the operation, the guide tube is first implanted into the blood vessel, and then Use the die to push out the mesh support. Although this "cardiovascular dilation device" can simplify the operation to a certain extent and improve the accuracy of the mesh stent in p...
