Description

Technical field:

[0001] The invention relates to the technical field of medical devices, and in particular to a visualized prostate fissure dilation catheter and a processing and forming device thereof. Background technology:

[0002] In the treatment of prostate diseases, prostate fissure dilation catheters play a key role. Traditional prostate fissure dilation catheter technology has many limitations and is difficult to meet the growing medical needs and expectations for technological development. From a functional perspective, most traditional catheters lack visualization. During the operation, doctors cannot observe the internal conditions of the prostate in real time and can only perform the operation based on experience and feel, which greatly increases the difficulty and uncertainty of the operation. This not only prolongs the operation time and increases the degree of pain for patients, but also increases the risk of surgery due to the difficulty in accurate positioning and operation, and greatly increases the probability of complications such as damage to the surrounding tissues of the prostate, bleeding or infection. At the structural level, traditional catheters are complex in design. In order to maintain the shape and function of some catheters, a supporting steel wire structure needs to be set up inside. This structure causes the catheter to have many parts and cumbersome assembly, which not only increases the production cost, but also reduces the utilization rate of parts, and brings inconvenience and waste of resources in the production, storage, transportation and use links. With the continuous advancement of medical technology and the increasingly stringent requirements of patients for treatment quality, it is urgent to develop prostate fissure dilation catheters with visualization functions, streamlined and efficient structures and their supporting processing and forming devices.

[0030] The use status of the present invention is as follows: the present invention has a reasonable and simple structure, low production cost, and convenient installation. When the visualized prostate fissure dilation catheter is used, a visualization hole 7 is provided in the center of the catheter body 1. Before the operation, a camera and an optical cable are inserted into the visualization hole 7 through the center hole 11, so that the doctor can observe the internal situation of the prostate in real time during the operation, accurately locate the lesion site and the operation area, and effectively improve the accuracy and safety of the operation. During the operation, the tube body 1 is inserted into the prostate site through the urethra to ensure that the insertion head 5 accurately reaches the target position, and liquid is injected into the cystic fluid hole 16 through the cystic fluid connector 10. The liquid passes through the through hole 8 to make the water bag 2 expansion; similarly, fluid is injected into the cystic fluid hole 24 through the cystic fluid connector 212, and the water bag 23 is expanded through the through hole 26. According to the surgical requirements, the expansion degree and pressure of the water bag are accurately controlled to achieve the expansion operation of the prostate, and alleviate the problems such as urethral obstruction caused by prostatic hyperplasia. During the catheter insertion process, according to the actual situation, the flushing fluid can be injected through the multifunctional hole 14 and the flushing diversion hole 15 connected thereto to remove impurities and secretions in the urethra and prostate, and ensure a clear surgical field of view and smooth operation. If necessary, a steel wire is temporarily inserted into the multifunctional hole 14 to enhance the hardness and controllability of the catheter, assist the smooth insertion of the catheter, and reduce the risk of damage to the urethral tissue;When the processing and forming device is used, the extruder 24 is first started, and according to the preset program and parameters, the tube body 1 and the internal sac fluid hole 24, sac fluid hole 16 and multiple multifunctional holes 14 are accurately extruded, and the extruded tube body 1 moves to the right along the guide hole 26 of the rotating seat 25. During this process, the cooling mechanism 23 operates synchronously, and the cooling hole 231 uses the annular hole 1 232, the annular hole 235, the input pipe 236, the return pipe 234 and the corresponding joints (input joint 237, return joint 238) to construct a cooling circulation system, so that the coolant circulates around the guide hole 26, quickly takes away the tube body 1 extruded. The heat during molding promotes the rapid shaping of the tube body 1, ensuring that its dimensional accuracy and physical properties meet the quality standards. When the extruded length of the tube body 1 reaches the set value and exceeds the right side of the guide hole 26, the motor 1 28 is started to drive the rotating seat 25 to rotate. The precise rotation of the rotating seat 25 cuts off and separates the extruded tube body 1, and at the same time rotates the empty guide hole 26 to the outlet of the extruder 24, preparing for the next round of tube extrusion, realizing a continuous and efficient production cycle, and improving processing efficiency and material utilization. During the punching process, the motor 3 291 is started to drive the screw 294 to rotate, driving the movable seat 293 along the guide groove 2 92 moves, so that the insert tube 297 is accurately inserted into the corresponding bladder fluid hole (bladder fluid hole 24 and bladder fluid hole 16), the piston rod of the punching cylinder 299 is extended, and the punching head at its end performs a punching operation on the outer side of the bladder fluid hole, punching out a through hole 26 and a through hole 18 on the bladder fluid hole 24 and the bladder fluid hole 16 respectively, to build a connecting channel for the subsequent water bag installation, the debris generated during the punching process is discharged through the chip discharge hole 298 of the insert tube 297, and is sucked away and cleaned in time by the vacuum cleaner 295, so as to maintain a clean processing environment and avoid the debris residue from adversely affecting the product quality and equipment operation. After the punching operation is completed, the punching machine The structure 29 returns to the initial position, the air valve 224 opens, and the sealed cavity 221 is inflated. At the same time, the motor 222 runs to loosen the drawstring 225, and the push block 226 pushes the punched tube body 1 out of the guide hole 26 under the coordinated action of air pressure and the relaxation of the drawstring. Then the air valve 224 is closed to exhaust, and the motor 222 is started in the reverse direction to tighten the drawstring 225 and pull back the push block 226 to prepare for the next tube body push operation. The cycle is repeated to efficiently complete the molding process of the visualized prostate dilation catheter, ensure stable product quality and smooth production process, and effectively meet the batch demand for such high-precision medical devices in the medical field. ;
