DETAILED DESCRIPTION

[0017] In order to enable a more detailed understanding of the features and technical contents of the present invention, the implementation of the present invention is described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference only and are not intended to limit the present invention.

[0018] like Figure 1-3 As shown, an embodiment of the utility model is a fast and accurate catheter ring cutting device, including a base box 1, a base 2, a clamping device 3, a positioning device 4, a fine-tuning device 5 and a safety cutting device 6. The base 2 is located above the base box 1 and is fixedly connected to the base box 1. The clamping device 3 is connected to the positioning device 4. The fine-tuning device 5 is fixed at one end of the positioning device 4. The safety cutting device 6 is located on one side of the positioning device 4.

[0019] The clamping device 3 includes a fixed block 31, a positioning claw flap 32, a fixed shaft 33, a movable shaft 34, a spring 35, a first pressure block 36, a second pressure block 37 and a transmission shaft 38. The fixed shaft 33 passes through the fixed block 31, the positioning claw flap 32 is connected to one end of the movable shaft 34, the positioning claw flap 32 and the movable shaft 34 pass through the fixed shaft 33 together, and the other end of the movable shaft 34 protrudes from one end of the fixed shaft 33. The first pressure block 36 is fixedly connected to the fixed shaft 33, and the second pressure block 37 is fixedly connected to the movable shaft 34. The spring 35 is installed between the first pressure block 36 and the second pressure block 37. The two ends of the spring 35 are respectively connected to the first pressure block 36 and the second pressure block 37. By compressing the second pressure block 37, the spring 35 is compressed so that the movable shaft 34 can drive the positioning claw flap 32 to move out of one end of the fixed shaft 33, and the transmission shaft 38 is connected to the second pressure block 37.

[0020] After the positioning claw 32 extends out of the fixed shaft 33, the catheter is inserted into the positioning claw 32, and the force compressing the second pressure block 37 is released. Under the action of the elastic force of the spring 35, the movable shaft 34 is reset, and the positioning claw 32 returns to the fixed shaft 33, and the axial direction of the catheter is fixed; at this time, the transmission shaft 38 is manually cranked, and the transmission shaft 38 drives the second pressure block 37 and the movable shaft 34 to rotate, and the movable shaft 34 drives the positioning claw 32 to rotate, and the positioning claw 32 drives the catheter to rotate 360° to achieve the circumcision operation.

[0021] The positioning device 4 includes a positioning block 41 and a slider 42. The positioning block 41 is fixedly connected to the base 2. Slide rails 411 are provided on both sides of the positioning block 41. The inner side of the slider 42 is provided with a bearing 421 that cooperates with the slide rail 411. The bearing 421 is located in the slide rail 411. The slider 42 is slidably connected to the positioning block 41, and the fixed block 31 is fixedly connected to the slider 42.

[0022] The fine-tuning device 5 includes a micrometer 51 and a fixed plate 52 , the micrometer 51 is connected to the fixed plate 52 , the fixed plate 52 is fixedly connected to the base 2 , the fine-tuning device 5 is installed at one end of the positioning device 4 , and the micrometer 51 is located at one end of the positioning block 41 .

[0023] The slider 42 can drive the catheter to move in the direction of the positioning block 41 through the fixed block 31. By rotating the micrometer 51, the end of the micrometer 51 is extended or shortened accordingly. Moving the slider 42 causes the fixed block 32 to drive the catheter to move in the direction of the micrometer 51. When the side of the fixed block 31 contacts the end of the micrometer 51, the catheter no longer moves forward and the final position of the catheter is determined. Since the annular cutting of the catheter has a tolerance within 0.05 mm, the micrometer 51 must be used for adjustment. If the end distance is long, the radial cutting depth of the catheter is shallow; if the end distance is short, the radial cutting depth of the catheter is correspondingly deeper.

[0024] The safety cutting device 6 includes a cutting wheel 61, a baffle 62, and a motor. The motor is located in the base box 1. The cutting wheel 61 is connected to the motor. Part of the cutting wheel 61 is located in the base box 1 and part of it protrudes from the top of the base 2. The baffle 62 is an L-shaped baffle with a cutting groove 621 at one end and the other end fixedly connected to the base 2 by screws. The baffle 62 is located on one side of the cutting wheel 61.

[0025] The safety cutting device 6 is located on one side of the positioning device 4. When the catheter moves toward the micrometer along with the slider, the catheter gradually approaches the cutting wheel 4. The baffle is designed with a cutting groove 51, the purpose of which is to ensure that the catheter can pass through the baffle when cutting. During the catheter cutting operation, one hand rotates the transmission shaft 38 of the clamping device 3 and the other hand holds the catheter. With the baffle 62 blocking it, the operator's operating hand will not touch the cutting wheel 61, thereby improving the safety factor of the equipment.

[0026] The specific usage process of the embodiment of the utility model is as follows:

[0027] First, adjust the micrometer 51 according to the required circumcision depth, then compress the second pressure block 37, the positioning claw 32 extends the fixed shaft 33, insert the catheter into the positioning claw 32, release the force of compressing the second pressure block 37, the positioning claw 32 is reset, the catheter is fixed, and then turn on the motor, the cutting wheel 61 starts to work, the operator holds the catheter with one hand and the rotating shaft 38 with the other hand, and moves the slider 42 to move the catheter toward the cutting wheel 61. When the side wall of the fixed block 31 contacts the end 511 of the micrometer 51, the catheter can no longer move forward and the cutting depth is fixed. Rotate the transmission shaft 38 as needed, and the catheter will also rotate 360 degrees to complete the circumcision operation. The catheter circumcision process requires the operator to conduct continuous trial cutting and continuous testing, and finally find the best process parameters before the catheter is officially circumcised.

[0028] The present invention adds a fine-tuning device 5 and a positioning device 4. The micrometer 51 in the fine-tuning device 5 can achieve high-precision measurement, so that the depth of each catheter cutting can be accurately controlled, greatly improving the cutting accuracy. Due to the presence of the positioning structure, the efficiency of each cutting is guaranteed. Before cutting the same batch of catheters, only one adjustment of the positioning structure is required, which saves time, improves work efficiency, and is also beneficial to the market competitiveness of the product. The baffle 62 design of the safety cutting device 6 can effectively protect workers. At the same time, the design of the cutting groove 621 does not affect the processing of the product at all while ensuring safety.

[0029] The utility model can not only meet the high precision requirement but also ensure the processing efficiency and high safety.

[0030] Here, the specific models of the above-mentioned devices are not limited or described in detail, and the in-depth connection methods of the above-mentioned devices are not described in detail. As common knowledge, those skilled in the art can understand it.

[0031] The embodiments of the present utility model are only to introduce its specific implementation methods and are not intended to limit its scope of protection. Those skilled in the art may make certain modifications inspired by the embodiments, so any equivalent changes or modifications made in accordance with the scope of the present utility model patent shall fall within the scope of the claims of the present utility model patent.
