Description

Technical Field

[0001] The invention belongs to the technical field of hypotube grinding, and in particular relates to an adjustable medical hypotube grinding device. Background Art

[0002] A hypotube is a long metal tube with micro-engineering properties throughout its entire pipeline. It is an important component of minimally invasive treatment catheters and needs to be used in conjunction with balloons and stents to open arterial blockages. The balloon portion of the catheter is attached to the distal end of the hypotube. The hypotube enters the human body and pushes the balloon along the tortuous and complex long blood vessels to the blocked artery. During this process, the hypotube needs to avoid kinking while being able to move smoothly in the human structure.

[0003] Since the hypotube is relatively small, it is necessary to use a grinding pen to grind it individually when grinding it, and the efficiency of grinding the hypotube is low. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an adjustable medical hypotube grinding equipment, which realizes different effects by changing the motion state of the umbrella-shaped structure formed by the driving rod and the spacer plate. In the initial planar state, the position of the hypotube can be well restricted in cooperation with the feeding auxiliary plate 1 and the feeding auxiliary plate 2, so as to prevent the hypotube with unstable center of gravity from moving from the center to the surroundings in advance. Then, the umbrella-shaped structure is slowly closed, so that the hypotube to be ground thereon slides from the center to the surroundings, effectively preventing the position of the hypotube to be processed from shifting during the grinding process. Finally, the equipment returns to the planar structure again and is ground in cooperation with the grinding box, thereby improving the grinding efficiency of the hypotube. Moreover, during the grinding process, the placement plate can support the hypotube to prevent it from bending.

At the same time, the coil 1 and the coil 2 are energized, and the coil 1 and the coil 2 are energized to generate the same magnetism, which will cause the feed auxiliary plate 1 and the feed auxiliary plate 2 that are in contact with each other to move away from each other. At this time, the feed port is open, and the medical hypotube can move down.

[0007] Furthermore, a driving disk is provided on the upper end of the central rod, and a driving rod is rotatably provided on the side wall of the driving disk, and the driving rod and the feed tray adopt opposite control interfaces; when the driving rod and the feed tray are started at the same time, the driving rod and the feed tray will rotate in opposite directions, and at the same time, coil one and coil two are in an energized state, and the driving rod pushes each sea wave tube into the gap between the feed auxiliary plate one and the feed auxiliary plate two in the feed port, and the rotating feed tray is responsible for corresponding to the different positions of the sea wave tube discharge control component.

[0008] Furthermore, the sea wave tube discharge control assembly includes a partition plate and a partition material guide mechanism, the partition plate is arranged on the center plate, the partition material guide mechanism is arranged on the upper wall of the partition plate, the partition material guide mechanism is arranged in multiple groups, and the multiple groups of the partition material guide mechanisms are arranged in a circular array, each group of the partition material guide mechanisms includes a rectangular groove and a circular groove, the rectangular groove is opened on the upper wall of the partition plate, the rectangular groove matches the feed port, and the circular groove is arranged on the inner bottom wall of the rectangular groove; each rotation of the feed tray will align the feed port on the feed tray with a different rectangular groove, as the driving rod and the feed tray rotate in opposite directions, each time the feed port on the feed tray is aligned with the rectangular groove, the driving rod will push the scattered sea wave tubes on the feed tray into the circular groove on the rectangular groove, until all the circular grooves on the partition plate are occupied by the sea wave tubes to be ground, and the operation of the driving rod and the feed tray is stopped.

Since the telescopic connecting rod is always at the highest point, the telescopic connecting rod at this time is also in the longest state, and the control partition plate is in a horizontal state as a whole, and then the lifting cylinder is gradually shortened, and the lifting plate will gradually move down from the highest point. In the process of moving down, the telescopic connecting rod is still in a horizontal state, and at the same time, the telescopic connecting rod is slowly controlled to become shorter, so that the partition plate originally in a plane is lowered around and gradually becomes a contracted umbrella shape. At this time, the umbrella-shaped partition plate, the rectangular groove and the circular groove thereon are all in a state of high in the middle and low around, which will make the sea wave tube to be ground thereon slide from the center to the surroundings and enter the next grinding process.

[0010] Furthermore, a guide plate is provided on the upper wall of the bottom cavity, and a guide groove is provided on the guide plate. The guide groove is arranged in a semicircular shape and matches the circular groove. The partition plate in the initial state is in a plane state, which is convenient for the feeding of the sea wave tube to be ground, and the upper wall of the partition plate at this time will contact the bottom wall of the guide plate, then the sea wave tube to be ground entering the circular groove can be regarded as consisting of two semicircles, wherein the lower semicircle of the sea wave tube is in the annular groove, and the upper semicircle is clamped by the guide groove of the guide plate. The plane partition plate can well limit the position of the sea wave tube to prevent the sea wave tube from having an unstable center of gravity. The wave tube moves from the center to the surroundings in advance. At the same time, when the lifting cylinder is running, the partition plate that was originally in a plane is lowered on all sides and gradually becomes a contracted umbrella shape. The semicircular guide groove will no longer restrict the upper semicircle of the sea wave tube, and the rectangular groove and circular groove on the umbrella-shaped partition plate are in a state of high in the middle and low around, which will make the sea wave tube to be ground thereon slide from the center to the surroundings. When the sea wave tube finishes moving, the lifting cylinder is started again to make the umbrella-shaped partition plate return to a plane again. At this time, the sea wave tube is between the bottom wall of the guide plate and the partition plate, and the guide plate can clamp the sea wave tube at this time.

[0011] Furthermore, the hypotube discharging grinding assembly is composed of a plurality of hypotube grinding mechanisms, which are arranged in a circular array on the side wall of the bottom cavity, and each group of hypotube grinding mechanisms includes a grinding window, a sliding auxiliary plate, a parallel plate 1 and a parallel plate 2.

When the partition plate changes from the original plane to the umbrella shape, the four sides of the partition plate move down, and the sliding auxiliary plate is driven down by the parallel plate 1, and the grinding window is opened. The rectangular groove and the circular groove on the partition plate are in a state of high in the middle and low around, which will make the sea wave tube to be ground thereon slide from the center to the surroundings. When the sea wave tube finishes moving, the lifting cylinder is started again to make the umbrella-shaped partition plate return to the plane again. At this time, the sea wave tube is between the bottom wall of the guide plate and the partition plate, and the guide plate can clamp the sea wave tube at this time. The sea wave tube that exceeds the grinding window is the part that needs to be ground.

[0012] Furthermore, a grinding box is slidably connected to each of the grinding windows, and the grinding box matches the second parallel plate.

[0013] Furthermore, the side wall of the auxiliary cavity is made of elastic material.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows:

[0015] (1) The umbrella-shaped structure formed by the driving rod and the spacer plate is opened and closed by the lifting cylinder and the lifting plate. When it is opened, a circular plane is formed, and its surroundings are controlled by the guide groove. In conjunction with the driving rod and the feeding plate, the sea wave tube to be ground is pushed into the circular groove in the rectangular groove, so that the sea wave tubes are fed one by one without affecting each other. The sea wave tube to be ground entering the circular groove can be regarded as consisting of two semicircles, the lower semicircle is in the annular groove, and the upper semicircle is stuck by the guide groove of the guide plate. In conjunction with the plane spacer plate, the position of the sea wave tube can be well restricted to prevent the sea wave tube with unstable center of gravity from moving from the center to the surroundings in advance;

[0016] (2) until all the circular grooves on the partition plate are occupied by the hypotubes to be ground, the partition plate is started, so that the umbrella-shaped structure is slowly closed, and the semicircular guide grooves will no longer restrict the upper semicircle of the hypotube, and the rectangular grooves and circular grooves on the umbrella-shaped partition plate are in a state of being high in the middle and low around, which will make the hypotube to be ground thereon slide from the center to the surroundings, effectively preventing the hypotube to be processed from shifting during the grinding process;

[0017] (3) After the above process is completed, the umbrella-shaped partition plate returns to a flat shape again. At this time, the hypotube is between the bottom wall of the guide plate and the partition plate. The guide plate can clamp the hypotube at this time. Finally, one end of the hypotube is clamped and the other end enters the grinding box for grinding, which improves the grinding efficiency of the hypotube. In addition, during the grinding process, the placement plate can support the hypotube to prevent it from bending.

[0018] (4) In the initial state, the feed auxiliary plate 1 and the feed auxiliary plate 2 are in close contact with each other. The staff places the medical hypotube to be ground directly on the feed tray. The feed auxiliary plate 1 and the feed auxiliary plate 2 that are in close contact with each other ensure that the medical hypotube cannot fall at this time, thereby limiting the number of hypotubes that are ground.

[0033] A driving disk 18 is provided on the upper end of the central rod 5, and a driving rod 19 is rotatably provided on the side wall of the driving disk 18. The driving rod 19 and the feed tray 10 adopt opposite control interfaces; when the driving rod 19 and the feed tray 10 are started at the same time, the driving rod 19 and the feed tray 10 will rotate in opposite directions, and at the same time, the coil 12 and the coil 2 13 are in an energized state, and the driving rod 19 pushes each sea wave tube into the gap between the feed auxiliary plate 1 16 and the feed auxiliary plate 2 17 in the feed port 14, and the rotating feed tray 10 is responsible for corresponding to the different positions of the sea wave tube discharge control component 8.

The partition material guide mechanism 21 is arranged in multiple groups, and multiple groups of the partition material guide mechanisms 21 are arranged in a ring array. Each group of the partition material guide mechanisms 21 includes a rectangular groove 22 and a circular groove 23. The rectangular groove 22 is opened on the upper wall of the partition plate 20, and the rectangular groove 22 matches the feed port 14. The circular groove 23 is arranged at On the inner bottom wall of the rectangular groove 22; each rotation of the feed tray 10 will align the feed port 14 on the feed tray 10 with a different rectangular groove 22, as the drive rod 19 and the feed tray 10 rotate in opposite directions, each time the feed port 14 on the feed tray 10 is aligned with the rectangular groove 22, the drive rod 19 will push the scattered hypotubes on the feed tray 10 into the circular groove 23 on the rectangular groove 22, until all the circular grooves 23 on the partition plate 20 are occupied by hypotubes to be ground, and the operation of the drive rod 19 and the feed tray 10 is stopped.

[0035] The central rod 5 is slidably connected with a lifting plate 24, and a lifting cylinder 25 is provided on the inner bottom wall of the bottom cavity 1. The control end of the lifting cylinder 25 is connected to the bottom wall of the lifting plate 24, and a telescopic connecting rod 26 is provided on the side wall of the lifting plate 24.

The sliding rod 27 is connected to the bottom wall of the partition plate 20, and the telescopic connecting rod 26 is in a horizontal position; the lifting cylinder 25 in the initial state is in the longest state. In the longest state, the lifting cylinder 25 will make the lifting plate 24 at the highest point. Since the telescopic connecting rod 26 is always at the highest point, then at this time The telescopic connecting rod 26 is also in its longest state, controlling the partition plate 20 to be in a horizontal state as a whole. As the lifting cylinder 25 gradually shortens, the lifting plate 24 will gradually move down from the highest point. During the downward movement, the telescopic connecting rod 26 is still in a horizontal state. At the same time, the telescopic connecting rod 26 is slowly controlled to become shorter, so that the partition plate 20, which was originally in a plane, is lowered around and gradually becomes a contracted umbrella shape. At this time, the umbrella-shaped partition plate 20, the rectangular groove 22 and the circular groove 23 thereon are all in a state of being high in the middle and low around, which will cause the hypotube to be ground thereon to slide from the center to the surroundings and enter the next grinding process.

[0036] A guide plate 28 is provided on the upper wall of the bottom cavity 1, and a guide groove 29 is provided on the guide plate 28. The guide groove 29 is arranged in a semicircular shape, and the guide groove 29 matches the circular groove 23; the partition plate 20 in the initial state is in a plane state, which is convenient for the feeding of the sea wave tube to be ground, and the upper wall of the partition plate 20 at this time will contact the bottom wall of the guide plate 28, then the sea wave tube to be ground entering the circular groove 23 can be regarded as consisting of two semicircles, wherein the lower semicircle of the sea wave tube is in the annular groove, and the upper semicircle is clamped by the guide groove 29 of the guide plate 28, and the plane partition plate 20 can well limit the position of the sea wave tube to prevent the existence of sea wave tubes with unstable center of gravity. The wave tube moves from the center to the surroundings in advance. At the same time, when the lifting cylinder 25 is running, the partition plate 20, which was originally in a plane, is lowered on all sides and gradually becomes a contracted umbrella shape. The semicircular guide groove 29 will no longer restrict the upper semicircle of the sea wave tube, and the umbrella-shaped partition plate 20, the rectangular groove 22 and the circular groove 23 thereon are in a state of being high in the middle and low around, which will cause the sea wave tube to be ground thereon to slide from the center to the surroundings. When the sea wave tube finishes moving, the lifting cylinder 25 is started again, so that the umbrella-shaped partition plate 20 becomes flat again. At this time, the sea wave tube is between the bottom wall of the guide plate 28 and the partition plate 20, and the guide plate 28 can clamp the sea wave tube at this time.

The grinding window 30 is opened on the side wall of the bottom cavity 1, and the sliding auxiliary plate 31 is slidably connected to the inner wall of the bottom cavity 1, and the sliding auxiliary plate 31 matches the grinding window 30. The parallel plate 1 32 belongs to the sliding auxiliary plate 31, and a support spring 34 is provided on the parallel plate 1 32, and the other end of the support spring 34 is connected to the bottom wall of the guide plate 28. The parallel plate 2 33 is arranged on the parallel plate 1 32, and the parallel plate 2 33 passes through the grinding window 30; the partition plate 20 in the initial state is in a planar state, It is convenient for feeding the sea wave tube to be ground, and at this time the upper wall of the partition plate 20 will contact the bottom wall of the guide plate 28, and the bottom wall of the partition plate 20 will contact the parallel plate 32. When the partition plate 20 changes from the original plane to the umbrella shape, the surroundings of the partition plate 20 move down, and the sliding auxiliary plate 31 is driven to move down by the parallel plate 32, and the grinding window 30 is opened. The rectangular groove 22 and the circular groove 23 on the partition plate 20 are both in a state of high in the middle and low around, which will make the sea wave tube to be ground thereon slide from the center to the surroundings. When the sea wave tube moves, the lifting cylinder 25 is started again to make the umbrella-shaped partition plate 20 return to the plane again. At this time, the sea wave tube is between the bottom wall of the guide plate 28 and the partition plate 20, and the guide plate 28 can clamp the sea wave tube at this time. The sea wave tube that exceeds the grinding window 30 is the part that needs to be ground.

[0039] The side wall of the auxiliary cavity 2 is made of elastic material.

[0040] During specific use, the medical hypotube to be ground is placed by the staff above the hypotube feeding assembly 6 in the control cavity 4, and the two end ports of the feeding control plate 11 in the initial state are connected, that is, the feeding auxiliary plate 1 16 and the feeding auxiliary plate 2 17 in the initial state are in contact with each other, and the staff directly places the medical hypotube to be ground on the feeding tray 10, and the feeding auxiliary plate 1 16 and the feeding auxiliary plate 2 17 that are in contact with each other ensure that the medical hypotube will not fall at this time. At the same time, the coil 12 and the coil 2 13 are energized, and the coil 1 12 and the coil 2 13 are energized to generate the same magnetism, which will cause the feeding auxiliary plate 16 and the feeding auxiliary plate 2 17 that are in contact with each other to move away from each other. At this time, the feeding port 14 is open, and the medical hypotube can move down and start the drive at the same time. When the driving rod 19 and the feeding tray 10 are rotated in opposite directions, the driving rod 19 and the feeding tray 10 will rotate in opposite directions, and at the same time, the coil 12 and the coil 2 13 are in the energized state, and the driving rod 19 pushes each hypotube into the gap between the feeding auxiliary plate 16 and the feeding auxiliary plate 2 17 in the feeding port 14. Each rotation of the feeding tray 10 will align the feeding port 14 on the feeding tray 10 with different rectangular grooves 22. As the driving rod 19 and the feeding tray 10 rotate in opposite directions, each time the feeding port 14 on the feeding tray 10 is aligned with the rectangular groove 22, the driving rod 19 will push the hypotubes scattered on the feeding tray 10 into the circular grooves 23 on the rectangular grooves 22, until all the circular grooves 23 on the partition plate 20 are occupied by the hypotubes to be ground, and the operation of the driving rod 19 and the feeding tray 10 is stopped.

[0041] In the initial state, the lifting cylinder 25 is in its longest state. In the longest state, the lifting cylinder 25 will make the lifting plate 24 at the highest point. Since the telescopic connecting rod 26 is always at the highest point, the telescopic connecting rod 26 is also in its longest state at this time, and the control partition plate 20 is in a horizontal state as a whole, which is convenient for the feeding of the sea wave tube to be ground. At this time, the upper wall of the partition plate 20 will contact the bottom wall of the guide plate 28, so the sea wave tube to be ground entering the circular groove 23 can be regarded as consisting of two semicircles, wherein the lower semicircle of the sea wave tube is in the annular groove, and the upper semicircle is clamped by the guide groove 29 of the guide plate 28, which can well limit the sea wave tube in cooperation with the plane partition plate 20. The semicircular guide groove 29 will no longer restrict the upper semicircle of the hypotube, and the rectangular groove 22 and the circular groove 23 of the umbrella-shaped partition plate 20 are both in a state of being high in the middle and low around, which will cause the hypotube to be ground thereon to slide from the center to the surroundings. After the hypotube moves, the lifting cylinder 25 is started again to make the umbrella-shaped partition plate 20 return to a plane again. At this time, the hypotube is between the bottom wall of the guide plate 28 and the partition plate 20, and the guide plate 28 can clamp the hypotube at this time. Finally, one end of the hypotube is clamped, and the other end enters the grinding box 35 to wait for grinding.
