Description

Technical Field

[0001] This application relates to the field of medical catheter processing technology, and more specifically, to a surface polishing device for the end of a catheter. Background Technology

[0002] Minimally invasive interventional surgery offers advantages such as small incisions, less bleeding, less patient pain, and faster postoperative recovery, leading to its increasingly widespread adoption and application in clinical practice. To ensure interventional instruments reach the intended site quickly and accurately, guiding devices are needed to establish a channel, such as catheter sheaths, balloon dilation catheters, guiding catheters, and adjustable-bend catheters. Therefore, medical catheters and sheaths play a crucial role in minimally invasive interventional treatments, especially in some complex procedures. To minimize damage to the body, strict requirements are placed on the safety and effectiveness of the channel. Braided tubing, with its excellent support, flexibility, and bending resistance, is widely used in the manufacturing process of medical catheters and sheaths. While ensuring the safety and effectiveness of the channel, it can also significantly reduce surgical time and effectively improve surgical efficiency.

[0003] Current medical market demands require grinding the outer layer of one end of tubing materials such as braided tubing, multi-lumen tubing, or single-lumen tubing. The outer diameter of the ground section is reduced, exposing the braided fibers in the middle layer. A step is formed between the ground and unground ends to facilitate the connection of multiple tubing sections. However, existing grinding methods mostly involve manual grinding or grinding the middle of the tubing after clamping it on both sides, making it impossible to grind both sides of the tubing. Utility Model Content

[0004] The purpose of this application is to provide a surface grinding device for the end of a pipe body, so as to achieve grinding treatment on the end of the pipe body.

[0005] In a first aspect, embodiments of this application provide a surface polishing device for the end of a tube, comprising: a frame, a clamping assembly, and a first driving mechanism. A polishing mechanism with a polishing hole is fixed to one end of the frame. The clamping assembly has a clamping hole and is located on one side of the polishing mechanism. The clamping assembly is slidably disposed on the frame to adjust the distance between the clamping hole and the polishing hole, so that one end of the tube is fixed in the clamping hole, and the other end extends into the polishing hole. The first driving mechanism drives the clamping assembly to rotate the tube fixed on the clamping assembly within the polishing hole for polishing.

[0006] The grinding equipment includes a frame, a clamping assembly, and a first driving mechanism. The grinding mechanism is located at one end of the frame and has a grinding hole for grinding the end of the tube. The clamping assembly has a clamping hole for clamping and fixing the tube, preventing displacement or damage during grinding and improving grinding accuracy. The clamping assembly is slidably mounted on the frame, allowing it to move the tube closer to or further away from the grinding mechanism to adjust the distance between the clamping hole and the grinding hole, so that the end of the tube to be ground extends into the grinding hole, achieving grinding. The grinding process involves a first driving mechanism connected to a clamping assembly, which provides driving force to the clamping assembly, allowing the clamped tube to rotate within the grinding hole. This enables full-circle grinding of the tube end. If bilateral grinding is required, the tube at one end can be removed, and the un-grinded portion at the other end can be ground in the same manner, thus achieving bilateral grinding of the tube. The grinding equipment of this application can replace manual labor, improve production efficiency, adjust the tube displacement for feed grinding, and achieve high-precision grinding of both ends of the tube without damaging the tube during the grinding process.

[0007] In one possible implementation, the grinding mechanism includes a frame, a fixed plate, and multiple grinding discs. The frame is fixed to one end of the frame body, the fixed plate is fixedly disposed on the frame, the fixed plate has a first through hole inside, one end of the multiple grinding discs is fixed to the fixed plate circumferentially, and the other end is located in the first through hole and together defines the grinding hole.

[0008] In the above technical solution, the fixed plate is fixed to the frame by the frame, and the frame also plays a role in fixing the fixed plate, so that the fixed plate can be more stable during the grinding process; multiple grinding discs are set in the fixed plate and arranged around the first through hole of the fixed plate, so as to define the grinding hole of the required size, so as to adjust the size of the grinding tube and facilitate the subsequent grinding work.

[0009] In one possible implementation, the fixed plate is provided with multiple strip holes, the number of which corresponds one-to-one with the number of grinding discs. One end of the grinding disc is provided with a fixing member, which passes through the strip hole and is selectively fixed at any position in the strip hole, so as to adjust the length of the other end of the grinding disc extending into the first through hole, thereby adjusting the size of the grinding hole.

[0010] In the above technical solution, a fixing member is provided at one end of the grinding disc. The fixing member passes through the strip hole and is selectively fixed at any position in the strip hole. Therefore, by adjusting the position of the fixing member in the strip hole, the length of the other end of the grinding disc extending into the first through hole can be adjusted. In this way, the size of the grinding hole defined by multiple grinding discs can be adjusted, thereby making the grinding equipment suitable for grinding variable diameter pipes.

[0011] In one possible implementation, the grinding mechanism further includes a base fixedly connected to the frame, the base having a slot in which the frame is secured.

[0012] In the above technical solution, the base can more firmly fix the grinding mechanism on the slide rail. At the same time, the frame is clamped in the slot of the base, which also facilitates the installation and disassembly of the grinding mechanism components.

[0013] In one possible implementation, the frame includes a slide rail and a base plate, the grinding mechanism is fixed to one end of the slide rail, the base plate is slidably disposed at the other end of the slide rail, and the clamping assembly is fixed to the base plate; the surface grinding equipment also includes a second drive mechanism, which drives the base plate to drive the clamping assembly to move the tube body along a direction close to or away from the grinding mechanism, so as to adjust the distance between the clamping hole and the grinding hole.

[0014] In the above technical solution, the clamping component is fixed on the base plate, and the base plate is slidably set on the slide rail. The second drive mechanism drives the base plate. Thus, under the driving action of the second drive mechanism, the base plate can drive the clamping component to reciprocate along the extension direction of the slide rail. This can adjust the distance between the clamping hole and the grinding hole, thereby realizing feed grinding. Since the clamping component is fixed on the base plate, the movement is more stable.

[0015] In one possible implementation, the clamping assembly includes a hollow shaft, a clamping member, and a clamping fixing plate. The extension direction of the hollow shaft is consistent with the extension direction of the slide rail. Both axial ends of the hollow shaft are fixed to the base plate. A first drive mechanism drives the hollow shaft to rotate. The clamping member is located between the hollow shaft and the grinding mechanism and has a clamping hole. The clamping hole is coaxially arranged with the hollow shaft. The clamping fixing plate is connected to the clamping member and is used to fix the tube body in the clamping hole and is fixedly connected to the hollow shaft.

[0016] In the above technical solution, the clamping component is located between the hollow shaft and the grinding mechanism and has a clamping hole. The clamping hole and the hollow shaft are coaxially arranged, so that the tube can be inserted through both the clamping hole and the hollow shaft at the same time, so that the side of the tube to be ground is close to the clamping component. The clamping fixing plate is connected to the clamping component and fixedly connected to the hollow shaft. Thus, the clamping component and the hollow shaft can be stably connected through the clamping fixing plate. The first driving mechanism drives the hollow shaft. Therefore, after the grinding equipment is started, since the hollow shaft and the clamping component are connected to each other, the hollow shaft can drive the clamping component to rotate together, thereby causing the tube to rotate, so as to better achieve grinding.

[0017] In one possible implementation, the clamping assembly further includes a first fixing member and a second fixing member, which are located at the two ends of the hollow shaft, respectively, so that the axial ends of the hollow shaft are fixed to the base plate.

[0018] In the above technical solution, the axial ends of the hollow shaft can be fixed to the base plate by the first and second fixing parts. The hollow shaft moves forward or backward by sliding on the slide rail through the base plate. It will not move forward or backward on its own, and the fixing of the axial ends does not affect its rotation. Therefore, during the grinding process, the tube can move forward or backward smoothly, improving the grinding accuracy and protecting the tube from damage.

[0019] In one possible implementation, the first driving mechanism includes a rotation drive member, a support frame, and a transmission gear. The support frame is disposed on a base plate, and the rotation drive member is disposed at the end of the support frame away from the base plate. The transmission gear is sleeved on the hollow shaft and fixedly connected to the hollow shaft. The rotation drive member drives the transmission gear to rotate, thereby causing the hollow shaft to rotate.

[0020] In the above technical solution, the rotation drive component is located at the end of the support frame away from the base plate; the transmission gear is sleeved on the hollow shaft and fixedly connected to the hollow shaft. That is to say, the rotation drive component and the hollow shaft form an upper and lower structure, and the rotation drive component drives the transmission gear. Under the driving action of the rotation drive component, the transmission gear can drive the hollow shaft to rotate, thereby driving the tube body to rotate, so as to realize rotational grinding.

[0021] In one possible implementation, the second drive mechanism includes a linear drive member, a connecting block and a coupling connected to each other, the connecting block being connected to the base plate; the axial direction of the coupling is the same as the extension direction of the slide rail, and the linear drive member drives the connecting coupling so that the coupling can drive the base plate to move along the extension direction of the slide rail.

[0022] In the above technical solution, the connecting block and the coupling can connect the base plate and the linear drive component. The axial direction of the coupling is the same as the extension direction of the slide rail. Therefore, under the driving action of the linear drive component, the base plate can move well along the extension direction of the slide rail, thereby driving the tube body to move along the extension direction of the slide rail to achieve feed grinding.

[0023] In one possible implementation, the slide rails include two rails, and the frame also includes multiple sliders. The multiple sliders are symmetrically slidably arranged on the two slide rails, and the other side is connected to the side of the base plate away from the clamping assembly. The sliders can drive the base plate to move along the extension direction of the slide rails.

[0024] In the above technical solution, the arrangement of two slide rails and multiple sliders can make the base plate move more stably on the slide rails. Attached Figure Description

[0041] This embodiment provides a surface polishing device for the end of a tube, including: a frame, a clamping assembly, and a first driving mechanism. A polishing mechanism with a polishing hole is fixed to one end of the frame. The clamping assembly has a clamping hole and is located on one side of the polishing mechanism. The clamping assembly is slidably mounted on the frame to adjust the distance between the clamping hole and the polishing hole, so that one end of the tube is fixed in the clamping hole, and the other end extends into the polishing hole. The first driving mechanism drives the clamping assembly, causing the tube fixed on the clamping assembly to rotate within the polishing hole for polishing.

[0042] like Figure 1 As shown, the grinding equipment provided in this application includes a frame, a clamping assembly, and a first driving mechanism. The frame primarily provides support for other components, and both the grinding mechanism and the clamping assembly are fixed to the frame. The grinding mechanism has a grinding hole for grinding the tube, and the clamping assembly has a clamping hole for clamping and fixing the tube. The clamping assembly can slide on the frame, so that during use, the distance between the clamping hole and the grinding hole can be adjusted as needed, so that one end of the tube is fixed in the clamping hole and the other end extends into the grinding hole, thereby achieving grinding of the end position of the tube. The first driving mechanism drives the clamping assembly to rotate the tube fixed on the clamping assembly in the grinding hole for grinding. That is, during use, after the clamping assembly fixes the tube, the distance between the tube and the clamping hole is adjusted so that the end area of ​​the tube to be ground extends into the grinding hole. At the same time, the first driving mechanism provides power to rotate the tube and begin grinding. After grinding one end of the tube, the tube can be removed, and the other end, which was not ground, can be ground in the same way, thus achieving grinding of both ends of the tube. In summary, this grinding equipment can replace manual grinding, improve production efficiency, and adjust the displacement of the tube while grinding to achieve a feed grinding function, allowing for grinding of both ends of the tube.

[0043] Please refer to Figures 4-6 The grinding mechanism of this application includes a frame 301, a fixed plate 302 and a plurality of grinding discs 303. The frame 301 is fixed to one end of the frame body, the fixed plate 302 is fixedly disposed on the frame 301, the fixed plate 302 has a first through hole inside, one end of the plurality of grinding discs 303 is fixed to the fixed plate 302 circumferentially, and the other end is located in the first through hole and together defines a grinding hole.

[0044] Multiple polishing discs 303 are embedded in a fixed disk 302. The fixed disk 302 has a first through hole inside. Each polishing disc 303 has a sharp corner at a certain angle. Figure 5As shown, multiple grinding discs 303 are arranged at a certain angle along the circumference of the grinding hole. One end of each grinding disc 303 is fixed circumferentially to the fixing plate 302, and the other end is located in the first through hole, collectively defining the grinding hole. In use, after the grinding discs 303 are embedded in the fixing plate 302, the frame 301 is used to fasten and fix the grinding discs 303 and the fixing plate 302 to prevent the grinding discs 303 from falling off. After adjusting the position of the tube body, the first drive mechanism is started, causing the tube body fixed on the clamping assembly to rotate in the grinding hole for grinding.

[0045] Furthermore, the fixed plate 302 is provided with a plurality of strip holes 304, the number of strip holes 304 corresponding one-to-one with the number of grinding discs 303. One end of the grinding disc 303 is provided with a fixing member 305, which passes through the strip hole 304 and is selectively fixed at any position of the strip hole 304, so as to adjust the length of the other end of the grinding disc 303 extending into the first through hole, thereby adjusting the size of the grinding hole.

[0046] Please continue to refer to Figure 5 The number of grinding discs 303 in this application can be freely combined. The more discs combined, the closer the shape of the grinding hole will be to a circle, which is more conducive to grinding the tube body. Meanwhile, the fixing member 305 of the grinding disc 303 can pass through the strip hole 304 on the fixing plate 302 and can be fixed at any position in the strip hole 304. Therefore, by moving the grinding disc 303, one end of the grinding disc 303, i.e., the fixing member 305, can be moved within the strip hole 304, thereby adjusting the length of the other end of the grinding disc 303 extending into the first through hole, thus adjusting the size of the grinding hole and achieving grinding of tube bodies of different sizes. In this application, after adjusting the size of the grinding hole by moving the grinding disc 303, the grinding disc 303 can be fixed using screws or other fixing members 305. This application does not limit the method of fixing the grinding disc 303.

[0047] As another way to adjust the size of the grinding hole, the fixed plate 302 can also be replaced. That is, the diameter of the slot 304 on the fixed plate 302 is fixed. After the grinding disc 303 is embedded in the fixed plate 302, the diameter of the grinding hole formed is a fixed diameter and cannot be adjusted. If it is necessary to grind pipes of different diameters, simply replace the fixed plate 302.

[0048] Under the action of this grinding mechanism, the grinding effect of variable diameter pipe body can be achieved. Variable diameter grinding can complete the grinding of a whole circle of the pipe body, that is, ring grinding. The grinding function is diverse and greatly improves the practicality of grinding equipment.

[0049] Furthermore, the grinding mechanism also includes a base 306 fixedly connected to the frame, the base 306 having a slot in which the frame 301 is secured. Please refer to... Figures 4-6 After the grinding disc 303 is embedded in the fixed plate 302, the fixed plate 302 is fixed using the frame 301. Then, the entire fixed plate 302 is snapped into the slot in the base 306, which is fixed to the slide rail 101, thus completing the assembly of the entire grinding mechanism. The slot design facilitates both fixing the fixed plate 302 to the slide rail 101 and replacing the fixed plate 302. For example, the size of the grinding hole can be adjusted by replacing the fixed plate 302, or the grinding disc 303 can be replaced if damaged. This detachable connection design provides greater flexibility.

[0050] In this application, the frame includes a slide rail 101 and a base plate 102. The grinding mechanism is fixed to one end of the slide rail 101, and the base plate 102 is slidably disposed at the other end of the slide rail 101. The clamping assembly is fixed to the base plate 102. The surface grinding equipment also includes a second drive mechanism. The second drive mechanism drives the base plate 102 and is used to drive the clamping assembly to move the tube body along the direction close to or away from the grinding mechanism, so as to adjust the distance between the clamping hole and the grinding hole.

[0051] Please refer to Figure 3 The base plate 102 is slidably mounted on the slide rail 101. The second drive mechanism is located at the bottom of the base plate 102 and is driven to drive the base plate 102. Thus, under the drive of the second drive mechanism, the base plate 102 can move along the extension direction of the slide rail 101. Since the clamping assembly is mounted on the base plate 102, the clamping assembly can move together with the base plate 102. Furthermore, the clamping assembly can drive the tube body to move in a direction closer to or further away from the grinding mechanism to adjust the distance between the clamping hole and the grinding hole, thereby achieving feed grinding.

[0052] In this application, the clamping assembly includes a hollow shaft 205, a clamping member 201, and a clamping fixing plate 202. The extension direction of the hollow shaft 205 is consistent with the extension direction of the slide rail 101. The two axial ends of the hollow shaft 205 are fixed to the base plate 102. The first driving mechanism drives the hollow shaft 205 to rotate. The clamping member 201 is located between the hollow shaft 205 and the grinding mechanism and has a clamping hole. The clamping hole is coaxially arranged with the hollow shaft 205. The clamping fixing plate 202 is connected to the clamping member 201 and is used to fix the tube body in the clamping hole and is fixedly connected to the hollow shaft 205.

[0053] Please refer to Figure 2In use, one end of the tube is inserted into the hollow shaft 205, and the other end is clamped by the clamping member 201, which is set close to the end of the hollow shaft 205. Then, the clamping member 201 and the hollow shaft 205 are connected and fixed by the clamping fixing plate 202, so that the hollow shaft 205 and the clamping member 201 form a whole. After the grinding equipment is started, under the drive of the first drive mechanism, the hollow shaft 205 can drive the clamping member 201 to rotate together, so that the tube can rotate together for rotational grinding. At the same time, under the drive of the second drive mechanism, the tube will move along the direction of approaching or moving away from the grinding mechanism, thereby adjusting the displacement of the tube and realizing feed grinding.

[0054] Furthermore, the clamping assembly also includes a first fixing member 203 and a second fixing member 204, which are located at both ends of the hollow shaft 205, so that the axial ends of the hollow shaft 205 are fixed to the base plate 102.

[0055] Please continue to refer to Figure 2 The first fixing member 203 and the second fixing member 204 are located at both ends of the hollow shaft 205, respectively. The first fixing member 203 is close to the clamping fixing plate 202, and the second fixing member 204 is close to the first driving mechanism. The first fixing member 203 and the second fixing member 204 are both fixed on the base plate 102. The clamping fixing plate 202, the first fixing member 203, the first driving mechanism and the second fixing member 204 are arranged in sequence. In this way, after the grinding equipment is started, the stability of the hollow shaft 205 and the tube can be maintained under the action of the first fixing member 203 and the second fixing member 204, so that the tube can move forward and backward smoothly during the grinding process without shifting left and right, which would affect the grinding accuracy or cause damage to the tube.

[0056] In this application, the first driving mechanism includes a rotation driving member 401, a support frame 402, and a transmission gear 403. The support frame 402 is disposed on the base plate 102, and the rotation driving member 401 is disposed at the end of the support frame 402 away from the base plate 102. The transmission gear 403 is sleeved on the hollow shaft 205 and fixedly connected to the hollow shaft 205. The rotation driving member 401 drives the transmission gear 403 to rotate, thereby driving the hollow shaft 205 to rotate.

[0057] Please continue to refer to Figure 2A first driving mechanism is provided at the end of the hollow shaft 205 away from the grinding mechanism. The first driving mechanism includes a rotation driving component 401, a support frame 402, and a transmission gear 403. The support frame 402 is mounted on the base plate 102. The rotation driving component 401 is located on the upper part of the base plate 102. The transmission gear 403 is a hollow gear and is sleeved on the hollow shaft 205. The rotation driving component 401, the transmission gear 403, and the hollow shaft 205 form an upper and lower structure. The rotation driving component 401 drives the transmission gear 403. Therefore, in use, the hollow shaft 205 is rotated by the transmission gear 403, and the transmission gear 403 is rotated by the rotation driving component 401.

[0058] As an example, the first drive mechanism includes a motor, a transmission belt, a support frame 402, and a transmission gear 403. The motor is fixed to the upper part of the support frame 402 and has a motor gear. The transmission gear 403 is sleeved on the hollow shaft 205, and the motor gear, the transmission gear 403, and the hollow shaft 205 form an upper and lower structure. The transmission belt connects the motor gear and the transmission gear 403. The transmission belt is driven to rotate by the motor gear, and the motor gear is driven by the motor as the total driving force.

[0059] In this application, the second drive mechanism includes a linear drive member 503, a connecting block 501 and a coupling 502 connected to each other. The connecting block 501 is connected to the base plate 102. The axial direction of the coupling 502 is the same as the extension direction of the slide rail 101. The linear drive member 503 drives the connecting coupling 502 so that the coupling 502 can drive the base plate 102 to move along the extension direction of the slide rail 101.

[0060] Please refer to Figure 3 and Figure 4 The coupling 502 is a telescopic structure, and the axial direction of the coupling 502 is the same as the extension direction of the slide rail 101. The base plate 102 and the coupling 502 are connected by the connecting block 501. The end of the coupling 502 away from the connecting block 501 is connected to the linear drive 503. Under the drive of the linear drive 503 as the total driving force, the coupling 502 can perform telescopic movement, thereby driving the base plate 102 to move along the extension direction of the slide rail 101, and then driving the tube body to move towards or away from the grinding mechanism to achieve feed grinding.

[0061] In this application, the slide rail 101 includes two rails, and the frame also includes multiple sliders 103. The multiple sliders 103 are symmetrically slidably arranged on the two slide rails 101, and the other side is connected to the side of the base plate 102 away from the clamping assembly. The sliders 103 can drive the base plate 102 to move along the extension direction of the slide rail 101.

[0062] Please refer to Figure 2 and Figure 3The slide rail 101 is provided with four sliders 103. The four sliders 103 are symmetrically arranged on the two slide rails 101. One side of each slider 103 is slidably connected to the slide rail 101, and the other side is connected to the bottom of the base plate 102. In this way, the four sliders 103 are fixed at the four corners of the bottom of the base plate 102 to maintain its stability. In this way, under the action of the sliders 103, the base plate 102 can reciprocate more stably on the slide rail 101.

[0063] As an example, one of the components of the slide rail 101 and the slider 103 is provided with a groove, and the other component is provided with a protrusion that mates with the groove.

[0064] The working principle of the polishing mechanism in this application is as follows:

[0065] In use, the tube to be ground is clamped and inserted into the hollow shaft 205. The hollow shaft 205 is then fixed using the first fixing member 203 and the second fixing member 204. The hollow shaft 205 is then inserted into the transmission gear 403. After the hollow shaft 205 is clamped in the transmission gear 403, the end of the tube to be ground is fixed onto the clamping member 201. Then, the clamping and fixing plate 202 is sleeved onto the clamping member 201, connecting the hollow shaft 205 and the clamping member 201, and the clamping and fixing are then secured. After the disc 202 is in place, adjust the size of the grinding hole according to the required dimensions (adjust the number of grinding discs 303 or replace the fixed disc 302 with one of the required size). Start the first drive mechanism to make the tube rotate at high speed, and then start the second drive mechanism to push the base plate 102 to move the entire clamping assembly along the extension direction of the slide rail 101, so that the grinding end of the tube is inserted into the grinding hole for grinding. During the entire grinding process, the size of the grinding hole can be freely adjusted to grind tubes of different diameters. After grinding one end, the tube can be removed, the other end can be reversed, and then ground. This allows for grinding of both ends of the tube. In summary, the grinding setup provided in this application not only enables manual grinding, improving production efficiency, but also allows for grinding of both sides of the tube and grinding of variable diameter tubes.

[0066] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
