Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, it relates to a composite catheter shaping and processing device. Background Art

[0002] In medical activities, for some detection and treatment activities, it is necessary to insert equipment deep into the human body. Through the guidance of a composite catheter, some areas inside the human body can be treated. Shaping the catheter can make the shape of the distal end of the catheter similar to the morphology of the corresponding position in the patient's body, facilitating more appropriate surgery, making the surgical operation smoother, and improving the treatment effect.

[0003] Most common shaping devices have a simple structure. For the diverse internal structures of different patients, most of them use shaping needles to shape and fix the catheter. However, this shaping method using shaping needles requires a large number of shaping needles to complete, and the shaping needles cannot be reused after use. When new shaping processing is carried out, new shaping needles need to be replaced, which easily causes waste of resources; moreover, for the stable progress of shaping, generally, the catheter is heated to raise its temperature and make it easy to deform for shaping. However, in common shaping devices, in order to provide a plastic space for the shaping needle, the heating device is generally arranged at the upper and lower ends, or even at the lower end. When heating, the catheter is not heated evenly, and the heating effect is not good; in addition, when shaping, the composite catheter is mostly directly placed in the shaping device, and the catheter is in direct contact with the shaping device, which cannot ensure the sterility of the catheter surface, making the catheter easily contaminated, and additional disinfection operations are required.

[0018] 1. A shaping space is provided through the cooperation of the base and the shaping groove, and a plastic effect is provided through the cooperation of multiple groups of electric telescopic push rods and the pressing and forming block.

During heating, instead of heating a single surface of the conduit, the temperature inside is raised to heat the entire conduit, making the heating uniform and improving the heating quality.

[0020] 3. The heat-conducting metal tube is fixed by a fixing ring and is internally communicated with a water injector. During heating, sterile water is injected into the heat-conducting metal tube through the water injector.

According to the shaping requirements, different electric telescopic push rods 3 are adjusted, so that the telescopic push rods push the pressure forming block 4 to move towards the middle of the plastic groove, and the stretching amplitudes of different telescopic push rods are different, so that different pressure forming blocks 4 stay at different positions, forming a suitable shaping space for shaping the composite catheter.

[0033] More specifically, when shaping, the composite catheter is inserted into the heat-conducting metal tube 5. Under the pressure of the pressure forming block 4, the heat-conducting metal tube 5 forms a suitable shape.

[0045] Specifically, the wire divider 18 is used to organize the wires, which are connected to multiple control heads 7 on the same side to control the heaters 6 on the same side, making it more convenient for the device to connect to external devices.

[0046] Please refer to Figure 1 and Figure 2 As a further implementation of the base: One end of the base 1 is provided with an access port 20, and the access port 20 is communicated with the shaping groove 2.

[0047] Specifically, during the plastic shaping process, the access port 20 provides space for the heat-conducting metal tube 5 to communicate with the outside, facilitating the loading or removal of the composite conduit.

[0048] In summary, when the overall device is in use or operation:

[0049] When using the device to shape the composite conduit, the device is supported by the base 1 and connected to an external power supply device. By controlling the electric telescopic push rods 3, multiple electric telescopic push rods 3 work independently. According to the shaping requirements, different electric telescopic push rods 3 are adjusted to make the telescopic push rods push the pressure-forming blocks 4 towards the middle of the plastic shaping groove. Moreover, the extension amplitudes of different telescopic push rods are different, so that different pressure-forming blocks 4 stay at different positions, forming a suitable shaping space. Through the cooperation of the threaded outer wall 11 and the threaded inner wall 12, the heat-conducting metal tube 5 is installed in the fixing ring 9. When replacement is needed, by rotating the heat-conducting metal tube 5, it can be removed from the fixing ring 9, which is convenient for operation. The pressure-forming block 4 moving towards the center cooperates with the heat-conducting metal tube 5 through the contact groove 17 and the heat-conducting pad 8. The contact groove 17 can better contact the heat-conducting metal tube 5, and the heat-conducting pad 8 is made of a softer material, which can produce a certain deformation to affect the bending of the heat-conducting metal tube 5. Under the combined extrusion of multiple pressure-forming blocks 4, the heat-conducting metal tube 5 deforms to present a shape that meets the composite plastic shaping requirements.

[0050] When shaping the composite catheter, a space is provided through the access port 20 for the heat-conducting metal tube 5 to communicate with the outside, facilitating the loading or unloading of the composite catheter. The composite catheter is inserted into the heat-conducting metal tube 5, and the heater 6 is controlled to operate through the control head 7. The wires are sorted by the wire splitter 18 and connected to multiple control heads 7 on the same side to control the heaters 6 on the same side. The heater 6 is an electric control device, and its specific model is not limited and can be purchased on the market. The heater 6 transfers heat to the heat-conducting pad 8, and the heat-conducting pad 8 fits with the heat-conducting metal tube 5 under the shaping of the contact groove 17, wrapping the heat-conducting metal tube 5. The heat-conducting pad 8 transfers heat to the heat-conducting metal tube 5, making the heat-conducting metal tube 5 evenly heated, and then transferring the heat to the internal composite catheter to make the composite catheter evenly heated. Then, as the heat-conducting metal tube 5 deforms, the shaping required by the composite is completed. Moreover, before shaping, sufficient sterile water is prepared, and the sterile water is injected into the heat-conducting metal tube 5 through the water injector 10, making the heat-conducting metal tube 5 in sterile contact with the composite catheter to ensure sterile and clean contact. And the injected sterile water will partially turn into steam under high-temperature heating, achieving the purpose of steam fumigation shaping of the catheter and improving the shaping effect. After the shaping structure, sterile water can also be continuously injected through the water injector 10 to provide a cooling effect. In addition, when shaping, the limiting cover 14 is rotated, so that the limiting cover 14 rotates along the base 1 through the rotating seat 13 and covers the device, which can block the upper end of the heat-conducting metal tube 5 and prevent the heat-conducting metal tube 5 from deforming upward, ensuring the stability of the shaping. And the cooperation state of the heat-conducting metal tube 5 and the pressure-forming block 4 can be observed through the observation port 15 to ensure the stable progress of the shaping.
