Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of controllable antibacterial contrast catheters, and particularly relates to a controllable antibacterial contrast catheter. Background Technique
[0002] A contrast catheter is a device for percutaneous angiography. The contrast catheter is a long rubber tube, and its main function is to provide a catheter to enable the contrast agent to be smoothly introduced into the blood vessel to produce a contrast effect.
[0003] For example, the Chinese patent with the publication number CN213642760U discloses a controllable antibacterial contrast catheter, including a connecting sleeve. A round hole is arranged inside the connecting sleeve. One side inside the round hole is fixedly connected with a first fixing sleeve. A first guiding sleeve is fixedly connected inside the first fixing sleeve. A limiting hole is arranged inside the first guiding sleeve. A through hole is arranged on one side of the first guiding sleeve and below the limiting hole. The other side inside the round hole is fixedly connected with a second fixing sleeve. A second guiding sleeve is fixedly connected in the middle of the second fixing sleeve. A limiting hole is arranged in the middle inside the second guiding sleeve. A catheter is arranged inside the first guiding sleeve and the second guiding sleeve. One end of the catheter close to the second fixing sleeve is fixedly connected with a connecting head. In the utility model, a fixing block is arranged, and the fixing block can be driven to move by a metal wire. One end of the fixing block is fixed on the surface of the catheter, so that the catheter can be quickly bent at a certain angle.
[0004] The above patent has the following problems:
[0005] There are some disadvantages when the above patent is used. For example, during the use of the device, only the angle of the catheter in one direction can be adjusted. If the bending angle of the catheter is too large, it is not convenient to finely adjust the catheter in the opposite direction. Moreover, after the device is adjusted, the position of the metal wire cannot be fixed, and the staff needs to hold the metal wire all the time, which is rather inconvenient. In view of this, we propose a controllable antibacterial contrast catheter. Content of the Utility Model
[0006] The purpose of the utility model is to provide a controllable antibacterial contrast catheter to solve the problems put forward in the above background technique.
[0007] In view of this, the utility model provides a controllable antibacterial contrast catheter, including:
[0008] A sleeve, one end of the sleeve is fixedly installed with a mounting block, three guide sleeves are fixedly installed inside the sleeve, a limiting hole is opened inside the guide sleeve, a through hole one and a through hole two are respectively opened above and below the limiting hole inside the guide sleeve, a catheter body is arranged inside the three limiting holes, two fixing blocks are fixedly installed on the catheter body at a position far from the mounting block, and a connecting head is fixedly installed at one end of the catheter body;
[0009] A through groove is opened in the mounting block, guide grooves are respectively opened at the top and bottom of the through groove inside the mounting block, sliding grooves are respectively opened on one side far from each other of the two guide grooves inside the mounting block, a pressing block is slidably installed inside the sliding groove, a metal wire is arranged inside the guide groove, one end of one of the metal wires passes through the three through holes one and is fixedly connected with one of the fixing blocks, and one end of the other metal wire passes through the three through holes two and is fixedly connected with the other fixing block;
[0010] Two driving components are respectively located inside the two sliding grooves and are respectively used to drive the two pressing blocks to displace.
[0011] In this technical solution, during use, the staff can pull one of the metal wires. Subsequently, one of the metal wires will slide inside the three through holes one to ensure the stability of one of the metal wires. Subsequently, one of the metal wires will drive one of the fixing blocks to displace, so that one end of the catheter body can be bent, and the connecting head will also move towards the specified position. Moreover, the other metal wire can be pulled to make the other metal wire slide inside the three through holes two to ensure the stability of the other metal wire. Subsequently, the other metal wire will drive the other fixing block to displace, and the other fixing block will drive the catheter body to be finely adjusted. Under the action of the two metal wires, it is ensured that the connecting head can be accurately displaced to the specified position, so as to be able to perform directional input. Under the action of the three limiting holes, it is ensured that the displacement of the catheter body is more stable;
[0012] After adjusting the position of the connecting head, through one of the driving components, one of the driving components drives one of the pressing blocks to displace downward. At this time, one of the rubber pads on one of the pressing blocks will displace downward until one of the pressing blocks enters one of the guide grooves, and one of the pressing blocks will contact and press one of the metal wires, so as to be able to fix the position of one of the metal wires and make one of the metal wires no longer continue to displace. Then, through the other driving component, the other driving component drives the other pressing block to displace upward. Subsequently, the other pressing block displaces upward and presses and fixes the other metal wire.
[0013] In the above technical solution, further, the driving component includes:
[0014] A threaded rod is rotatably installed in the chute. One end of the threaded rod extends into the extrusion block, and the other end of the threaded rod penetrates through the chute and extends to the outside and is fixedly installed with a handle.
[0015] In this technical solution, rotate the handle so that the handle drives the threaded rod to rotate. Under the action of the thread, the rotation of the threaded rod will drive the extrusion block to displace.
[0016] In the above technical solution, further, the extrusion block is in threaded connection with the threaded rod.
[0017] In this technical solution, under the action of the thread, the rotation of the threaded rod will drive the extrusion block to displace.
[0018] In the above technical solution, further, rubber pads are fixedly installed on the opposite sides of the two extrusion blocks.
[0019] In this technical solution, under the action of the rubber pad, the material of the rubber pad is relatively soft, which can avoid damaging the metal wire. Moreover, the connecting head can increase the friction force between the extrusion block and the metal wire, so that the metal wire can be fixed more stably.
[0020] In the above technical solution, further, the other end of the conduit body passes through the through groove and extends to the outside. One of the metal wires is slidably connected to the first through hole, and the other metal wire is slidably connected to the second through hole.
[0021] In this technical solution, it is ensured that personnel can adjust the position of the conduit body by holding the other end of the conduit body; it is ensured that one of the metal wires can slide in the three first through holes; it is ensured that the other metal wire can slide in the three second through holes.
[0022] In the above technical solution, further, the three guide sleeves are linearly and equidistantly distributed.
[0023] In this technical solution, it is ensured that the three guide sleeves can effectively support the two metal wires and the conduit body.
[0024] In the above technical solution, further, the sleeve is located between the fixed block and the mounting block.
[0025] In this technical solution, it is ensured that the three guide sleeves in the sleeve can guide the two metal wires and the conduit body, making it more stable during displacement.
[0026] The beneficial effects of the present utility model are:
[0027] 1. The controllable antibacterial contrast catheter, through the cooperation between the two metal wires and the two fixing blocks, ensures that one end of the catheter body can be bent and adjusted in two directions, with a better adjustment effect, enabling the connector at one end of the catheter body to be accurately adjusted and ensuring that the connector can be displaced to the specified position.
[0028] 2. The controllable antibacterial contrast catheter, through the cooperation between the extrusion block, the sliding groove, the guiding groove and the driving component, can fix the position of the metal wire after the position of the connector is adjusted, eliminating the need for personnel to hold the metal wire by hand, which is more convenient.
