Description

Technical Field

[0001] The utility model relates to the technical field of hypotube processing and manufacturing, in particular to a hypotube positioning tool. Background Art

[0002] Minimally invasive interventional medicine or minimally invasive medical technology is a new technology that has developed rapidly in recent years. It has opened a new chapter in medical science and technology. Minimally invasive interventional medicine is a diagnostic and therapeutic operation performed by using a series of interventional instruments and materials (or minimally invasive instruments and materials) and modern digital diagnostic and treatment equipment. Compared with traditional surgical operations, interventional treatment does not require surgery and has the advantages of less bleeding, less trauma, fewer complications, safety and reliability, and faster postoperative recovery. It greatly reduces the pain suffered by patients, reduces the difficulty of operation for surgeons, significantly shortens the operation time and hospitalization time, and significantly reduces costs.

[0003] Medical catheters are important instruments for minimally invasive interventional treatment. Medical catheters use a variety of materials, mainly including biomedical materials, medical catheter plastics, etc., and their different properties are used in medical catheters for different purposes, such as interventional cardiac catheters, peripheral catheters, cranial nerves, extension catheters, etc. During minimally invasive interventional surgery, in order to accurately deliver minimally invasive instruments to the lesion site and protect the minimally invasive instruments from falling off when they reach the lesion site, a protective sleeve will be placed on the outside of the minimally invasive instruments, and the steel wire (i.e., hypotube) with a coating on the surface (the coating is to prevent thrombosis) will push and withdraw the minimally invasive instruments synchronously into the lesion area. The hypotube is used to protect minimally invasive instruments and prevent them from falling off during transportation, causing medical accidents. In order to observe the pushing distance from the outside during the pushing process, the coating on the metal steel wire needs to be removed at a fixed point to expose the metal color to preliminarily determine the pushing distance, so that doctors can accurately grasp the minimally invasive instruments during the operation.

[0004] In the production process of sea wave tubes, various tooling fixtures are needed to keep them fixed for subsequent processing. However, the existing fixtures are first fixed from both sides, which is prone to deviation. Secondly, they cannot be moved after being fixed. If rotation and other operations are required, the staff needs to change the position by themselves, which is troublesome. Utility Model Content

At the same time, the top rod and the rotating head can be pressed and fixed from both upper and lower directions, and the hypotube can be driven to rotate and other operations, and the use effect is good.

[0006] In order to solve the above technical problems, the utility model provides a sea wave tube positioning tool, including a working plate, a vertical plate is arranged on the working plate, a horizontal plate is arranged on the vertical plate, a base is arranged on the side of the upper surface of the working plate close to the vertical plate, a first through hole is arranged at the center of the base, a telescopic cylinder is arranged at the bottom of the base, a push rod passing through the first through hole is arranged at the output end of the telescopic cylinder, a carrier seat is arranged on the base at a position corresponding to the push rod, and a second through hole is arranged at the center of the carrier seat at a position corresponding to the push rod; a movable track is arranged on the vertical plate, a movable plate is arranged on the movable track, a driving structure is arranged on one side of the movable plate, and a rotating head is arranged at the bottom of the movable plate.

[0007] Furthermore, the base and the working plate are provided with telescopic axes, and the telescopic axes are distributed at four corners of the base.

[0008] Furthermore, the end of the push rod is provided with a curved surface structure.

[0009] Furthermore, limit rods are provided at the upper and lower sides of the vertical plate at positions corresponding to the movable plate.

[0013] Furthermore, reinforcing ribs are provided between the vertical plate and the working plate.

[0014] The beneficial effects of the utility model are as follows: when the device is used, the material is put into the second through hole, and the telescopic cylinder on the base is adjusted first. The telescopic cylinder is started to drive the top push rod to move up and down to adjust its position in the second through hole to adjust the position of the material. After the adjustment is completed, the driving structure on the top is started to drive the moving plate to move up and down on the moving track until it contacts and positions the top of the workpiece to achieve simultaneous fixation in the upper and lower directions.
