Description

Technical Field

[0001] This utility model relates to the technical field of catheter processing equipment, specifically a catheter cutting device that facilitates unloading. Background Technology

[0002] As an important medical device, urinary catheters are widely used in urology, postoperative care, and critical care settings. Their main function is to help patients drain urine and maintain the normal function of the urinary system. To meet the physiological needs of different patients and clinical usage scenarios, urinary catheters need to be cut to a specified length according to specific specifications before use. Therefore, the cutting process is a key step in the production and clinical preparation of urinary catheters.

[0003] In the prior art, the cutting table serves as a support platform for placing the catheter to be cut; the positioning component is mostly a baffle set at one end of the cutting table, which positions the cutting length by abutting one end of the catheter against the baffle, ensuring that the length of each catheter segment is consistent; the cutter is manually or electrically driven to cut the catheter along a preset trajectory.

[0004] This traditional cutting equipment has obvious defects in actual operation: after the cutting is completed, the cut catheter segment remains on the cutting table and needs to be manually removed by the operator (i.e., manual unloading) before the next catheter can be placed and cut. This operation process makes it inconvenient to carry out the cutting operation continuously and significantly reduces the overall work efficiency. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a catheter cutting device that facilitates unloading.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a catheter cutting device for easy unloading, including a processing table, a slot provided on the processing table, and a control switch located on one side of the slot at the upper end of the processing table;

[0009] The upper end of the processing table is fixedly provided with a first fixed seat, and the front end of the first fixed seat is provided with a split second fixed seat. The second fixed seat is located above the empty slot, and the front end of the second fixed seat contacts the rear end of the first fixed seat. The first fixed seat and the second fixed seat are provided with a communicating arc-shaped groove. The second fixed seat is provided with a knife groove and a baffle. The baffle is slidably connected to the second fixed seat.

[0010] A lifting assembly is fixedly installed above the empty slot, and a cutter is provided at the output end of the lifting assembly;

[0011] A motor is fixedly installed at the rear end of the processing table, and the output end of the motor is provided with a rotating shaft connected to the rear end of the second fixed base.

[0012] To facilitate the storage of the cut catheter, the present invention includes an improvement where a base plate is fixedly installed below the empty groove, and a receiving box is placed on the upper end of the base plate, with the receiving box located below the empty groove.

[0013] To improve the stability of the second fixed seat during use, the present invention includes the following improvements: two propulsion components are symmetrically arranged in the upper slot of the processing table; the output end of the propulsion component is provided with a limiting plate that contacts both sides of the second fixed seat; the propulsion component adopts an electric push rod; and the output end of the propulsion component is provided with a drive rod that connects to the limiting plate.

[0014] To improve the stability of the baffle during use, the present invention includes the following improvements: the upper end of the second fixed seat has two symmetrical arc-shaped grooves with two sliding grooves; the lower end of the baffle has two symmetrical sliders that slide in connection with the sliding grooves; the sliding grooves have a T-shaped cross-section; the baffle has positioning plates on both sides that contact the sides of the second fixed seat; the positioning plates have locking rods that pass through the positioning plates and abut against the second fixed seat at one end; the locking rods are threadedly connected to the positioning plates; and the outer wall of the second fixed seat has a scale strip.

[0015] Furthermore, an improvement of this utility model is that a fixing plate is provided at one end of the rotating shaft, and the fixing plate is fixed to the rear end of the second fixing seat by screws.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a catheter cutting device that facilitates unloading, and has the following beneficial effects:

[0018] The second fixed seat is rotated by a motor and a rotating shaft, so that the cut catheter segment falls into the receiving box through the empty groove. This replaces the traditional manual unloading, avoids the downtime of waiting for manual material retrieval after cutting, realizes continuous cutting operation, significantly improves overall work efficiency, and reduces the labor intensity of operators.

[0019] The baffle slides on the second fixed seat through the cooperation of the slider and the T-shaped groove. Combined with the scale strip, the position can be precisely adjusted to ensure that the cutting length is uniform after the catheter abuts the baffle. The cooperation between the positioning plate and the locking rod can firmly fix the position of the baffle, avoid the length deviation caused by the displacement of the baffle during the cutting process, and improve the cutting accuracy.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-3 This utility model proposes a catheter cutting device that facilitates unloading, including a processing table 1, on which a slot 2 is provided, and a control switch 10 located on one side of the slot 2 is provided at the upper end of the processing table 1.

[0026] The upper end of the processing table 1 is fixedly provided with a first fixed seat 7, and the front end of the first fixed seat 7 is provided with a split second fixed seat 8. The second fixed seat 8 is located above the empty slot 2, and the front end of the second fixed seat 8 contacts the rear end of the first fixed seat 7. The first fixed seat 7 and the second fixed seat 8 are provided with a communicating arc-shaped groove. The second fixed seat 8 is provided with a knife groove 9 and a baffle 13. The baffle 13 is slidably connected to the second fixed seat 8.

[0027] A lifting assembly 5 is fixedly installed above the empty slot 2, and a cutter 6 is provided at the output end of the lifting assembly 5;

[0028] A motor 11 is fixedly installed at the rear end of the processing table 1, and the output end of the motor 11 is provided with a rotating shaft 12 connected to the rear end of the second fixed seat 8.

[0029] A base plate 3 is fixedly installed below the empty trough 2, and a receiving box 4 is placed on the upper end of the base plate 3. The receiving box 4 is located below the empty trough 2.

[0030] Before using this easy-to-unload catheter cutting device, the following preparations must be made:

[0031] The upper end of the second fixed seat 8 is provided with two sliding grooves 14 in a symmetrical arc-shaped groove. The lower end of the baffle 13 is provided with two sliders that are symmetrically connected to the sliding grooves 14. The cross section of the sliding groove 14 is T-shaped. The baffle 13 is provided with positioning plates 15 on both sides that contact the two sides of the second fixed seat 8. The positioning plates 15 are provided with locking rods 16. The locking rods 16 pass through the positioning plates 15 and one end abuts against the second fixed seat 8. The locking rods 16 are threadedly connected to the positioning plates 15. The outer wall of the second fixed seat 8 is provided with scale strips.

[0032] Rotate the locking rods 16 on the positioning plates 15 on both sides of the baffle 13 counterclockwise so that one end of it disengages from the second fixed seat 8, thereby releasing the baffle 13 from its position.

[0033] At this time, the slider at the lower end of the baffle 13 can slide along the slide groove 14 set in the symmetrical arc groove at the upper end of the second fixed seat 8 (the slide groove 14 has a T-shaped cross section to ensure the slider slides stably). Combined with the scale strip on the outer wall of the second fixed seat 8, adjust the position of the baffle 13. After the position is determined, rotate the locking rod 16 clockwise so that it abuts against the second fixed seat 8 again, and fix the baffle 13 by the positioning plate 15.

[0034] Then place the catheter to be cut: place the catheter workpiece into the arc-shaped groove that connects the first fixing seat 7 and the second fixing seat 8, and push the catheter so that its rear end abuts against the baffle 13 to complete the positioning of the cutting length.

[0035] Press the control switch 10 on one side of the empty slot 2 at the top of the processing table 1 to start the equipment:

[0036] Two propulsion components 17 are provided in the symmetrical slots 2 at the upper end of the processing table 1. The output end of the propulsion component 17 is provided with limiting plates 18 that contact the two sides of the second fixed seat 8. The propulsion component 17 adopts an electric push rod, and the output end of the propulsion component 17 is provided with a drive rod that connects to the limiting plates 18.

[0037] First, the two propulsion components 17 (using electric push rods) set in the symmetrical empty slots 2 at the upper end of the processing table 1 are started. The drive rods at their output ends push the limiting plates 18 to move inward, so that the two limiting plates 18 are in close contact with the two sides of the second fixed seat 8, forming a clamping and fixing of the second fixed seat 8.

[0038] Next, the cutting operation is carried out: the lifting component 5 above the empty groove 2 is activated, and its output end drives the cutter 6 to descend. The cutter 6 passes through the blade groove 9 on the second fixed seat 8 and cuts the catheter in the arc-shaped groove.

[0039] After the cutting is completed, the lifting assembly 5 drives the cutter 6 to reset, and at this time the cut catheter segment remains in the arc-shaped groove of the second fixing seat 8.

[0040] Then the unloading process begins: the propulsion component 17 drives the limit plate 18 to reset, releasing the clamp on the second fixed seat 8;

[0041] One end of the rotating shaft 12 is provided with a fixing plate, which is fixed to the rear end of the second fixing seat 8 by screws.

[0042] When the motor 11 at the rear end of the processing table 1 starts, the shaft 12 at its output end drives the second fixed seat 8 to rotate 180 degrees, causing the second fixed seat 8 to flip so that the opening of the arc groove faces downward. The cut catheter segment slides down from the arc groove and falls into the receiving box 4 placed on the upper end of the bottom plate 3 through the empty slot 2 of the processing table 1.

[0043] After unloading, the motor 11 drives the rotating shaft 12 to reverse and reset the second fixed seat 8. The push assembly 17 drives the limit plate 18 to clamp and fix the second fixed seat 8 again. The equipment returns to its initial state and can carry out the next cutting operation. Then, the catheter workpiece to be cut is pushed again so that the rear end of the catheter workpiece contacts the baffle 13 again.

[0044] The propulsion assembly 17 drives the limiting plate 18 to clamp the second fixed seat 8 through the drive rod, so as to prevent the second fixed seat 8 from shaking during cutting and flipping; the rotating shaft 12 is connected to the second fixed seat 8 through the fixing plate and screws to ensure the stability of the flipping action; the cooperation between the T-shaped slide 14 and the slider restricts the up and down displacement of the baffle 13, further ensuring the positioning stability and reducing the risk of failure during equipment operation.

[0045] The control switch 10 is integrated into the processing table 1. One-button start can complete the linkage operation of clamping, cutting and unloading. The position of the baffle 13 can be flexibly adjusted. With the help of the scale strip, it can adapt to the cutting needs of catheters of different lengths. The operation is simple and easy to learn, reducing the skill requirements of the operator.

[0046] The storage is orderly and meets cleanliness standards: the cut catheter segments fall directly into the receiving box 4 below the empty trough 2, reducing manual contact and lowering the risk of contamination in the medical setting; the receiving box 4 is placed on the base plate 3, which facilitates centralized storage and subsequent processing, keeping the working environment clean.

[0047] Control switch 10:

[0048] Type: Multi-position self-locking push-button switch (with emergency stop function);

[0049] Core parameters:

[0050] Gear settings: at least 3 gears (start / stop / emergency stop). The start gear triggers the equipment to run in conjunction with the system, the stop gear interrupts the process, and the emergency stop gear is used to force a power cut-off in case of an emergency.

[0051] Protection rating: IP54 and above (dustproof and splashproof), suitable for clean environments for medical equipment;

[0052] Material: The outer shell is made of ABS engineering plastic (resistant to alcohol wiping, meeting the disinfection requirements of medical scenarios), and the button travel is 2-3mm (clear operation feedback to avoid accidental touch).

[0053] Reasons for selection: Precise control of the linkage sequence of propulsion component 17, lifting component 5, and motor 11 is required; the self-locking function can prevent accidental start-up of the equipment due to accidental contact; the emergency stop function ensures operational safety, especially in medical scenarios where emergencies need to be dealt with.

[0054] Lifting component 5 (drives the cutter 6 to lift):

[0055] Type: Small DC electric linear actuator (replaces pneumatic linear actuators, avoiding dependence on air source);

[0056] Core parameters:

[0057] Drive method: DC permanent magnet motor 11 (noise ≤55dB, suitable for low noise requirements in medical scenarios);

[0058] Stroke: 50-80mm (to meet the distance required for the cutter 6 to descend from its initial position to its reset position after cutting the catheter);

[0059] Load: 10-30N (the catheter is soft and does not require much force; avoid excessive cutting to prevent catheter deformation);

[0060] Speed: 30-50mm / s (moderate descent speed to ensure smooth cutting and avoid guide slippage);

[0061] Additional features: Built-in limit switches (upper and lower limits to prevent the cutter 6 from overtraveling and damaging the cutter groove 9 or the second fixing seat 8).

[0062] Reasons for selection: The electric actuator has high control precision and can be precisely triggered by the control switch 10 to lift and lower the rod in sync with the cutting process; there is no risk of air leakage from pneumatic components, maintenance is simpler, and it is suitable for the stability requirements of medical equipment.

[0063] Motor 11 (drives the second fixed base 8 to rotate):

[0064] Type: DC geared motor (with forward / reverse rotation and braking functions);

[0065] Core parameters:

[0066] Power: 10-30W (sufficient to rotate the second fixation seat 8 and the catheter by its weight);

[0067] Rotation speed: 30-50 r / min after deceleration (the rotation speed is gentle to avoid the catheter being thrown out or stuck due to centrifugal force during rotation);

[0068] Torque: 1-5 N·m (to ensure no slippage during 180° rotation, especially stable rotation when clamping the catheter);

[0069] Braking function: Locks immediately upon power failure (fixes the angle immediately after flipping into position to prevent material displacement due to inertial shaking);

[0070] Voltage: 12V or 24V DC (with the same power supply as lifting assembly 5 and propulsion assembly 17, simplifying circuit design).

[0071] Reasons for selection: The geared motor can provide stable torque, and the forward and reverse functions are compatible with the "flipping unloading-reset" action; the braking function ensures that the second fixed seat 8 remains horizontal during cutting and is accurately aligned with the empty slot 2 during unloading, thus improving the reliability of unloading.

[0072] Propulsion assembly 17 (electric actuator, driven by limit plate 18 for clamping):

[0073] Type: Miniature DC electric linear actuator;

[0074] Core parameters:

[0075] Stroke: 20-40mm (to satisfy the distance that the limiting plate 18 moves from its initial position to the clamping second fixing seat 8);

[0076] Thrust: 5-15N (moderate clamping force, which avoids the second fixing seat 8 from shaking and also prevents excessive squeezing from causing deformation);

[0077] Response speed: 20-30mm / s (quickly completes clamping / releasing actions, reducing process waiting time);

[0078] Synchronization: The two push rods must ensure synchronized movement (driven by the same control signal to ensure consistent clamping force of the limit plates 18 on both sides);

[0079] Material: The push rod body is made of stainless steel (rust-proof and suitable for clean environments).

[0080] Reasons for selection: The miniaturized design saves space on the processing table 1, and the DC drive is compatible with other equipment; precise thrust control protects the second fixed seat 8 (plastic or lightweight material) from mechanical damage, while ensuring stability during cutting.
