It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0023] Example one

[0024] Reference Figures 1 to 5The application relates to a tension-controllable wire drawing device for braided stents, which comprises a pay-off mechanism 1, a detection mechanism 2, a monitoring console 3, a wire drawing pen 4 and a mold fixing block; the monitoring console 3 comprises a base 31 and a control screen 32, and a pen holder 40 for placing the wire drawing pen 4 is further connected to one side of the control screen 32; the pay-off mechanism 1, the detection mechanism 2 and the control screen 32 are fixedly connected to the base 31 respectively; the pay-off mechanism 1 is connected to the wire drawing pen 4 through a wire; the control screen 32 is further electrically connected to the pay-off mechanism 1, the detection mechanism 2 and the wire drawing pen 4 respectively; a groove-shaped track is arranged on the base 31, and the mold fixing block is slidably connected to the base 31 through the track.

[0025] A grating ruler can be additionally installed on the groove track of the base 31 and is rigidly connected to the mold fixing block; a stepping motor is additionally installed on the side surface of the mold fixing block, the output shaft of the motor is connected to a gear, and the gear is engaged with the track rack. The X / Y axis positions of the mold fixing block are acquired in real time, and the sliding speed and displacement of the mold fixing block are accurately controlled.

[0026] The mold fixing block comprises a flat plate fixing block 5 and a cylindrical fixing block 6, the flat plate fixing block 5 is detachably connected with a flat plate support mold 8, and the cylindrical fixing block 6 is detachably connected with a cylindrical support mold 7; the flat plate support mold 8 and the cylindrical support mold 7 are both vertically fixed with wire winding nails 9 on the surfaces; the flat plate fixing block 5 is detachably connected with the flat plate support mold 8 through clamping, and the cylindrical fixing block 6 is detachably connected with the cylindrical support mold 7. Different diameters of molds can be adapted, in the use process, the mold needs to be axially rotated, and can be detachably connected through clamping or pneumatic clamping. The mold fixing block is used for placing or rotating the support mold, and cooperates with the wire drawing pen 4 in the artificial holding state to braid different wave-shaped stents.

[0027] The two ends of the cylindrical fixing block 6 are connected with coaxial rotating shafts, one side of the shaft is connected with a stepping motor, and the other side of the shaft is connected with a bearing seat; the output end of the stepping motor is further connected with a torque sensor for detecting the rotating resistance and avoiding the wire being too tight. The monitoring console sets the rotating speed, and the torque sensor automatically stops when the threshold value is exceeded.

[0028] The wire drawing pen 4 comprises a first handle 41, a connecting shaft 44 and a second handle 46, the head of the first handle 41 is rotatably connected to the head of the second handle 46 through the connecting shaft 44; a spring 45 is further connected between the first handle 41 and the second handle 46; a wire clamping block 42 is connected to the middle of the first handle 41, the wire clamping block 42 is of an upper-lower split structure and comprises an upper wire clamping block and a lower wire clamping block, the upper wire clamping block is fixed to the middle of the first handle 41, the lower wire clamping block is fixed to the corresponding position of the second handle 46, and a pressure sensor 43 is embeddedly integrated on the side of the lower wire clamping block facing the wire, and the pressure sensor 43 is electrically connected to the monitoring console 3. When the wire drawing pen is held, the upper and lower wire clamping blocks bite and extrude the wire, the pressure sensor collects the clamping force signals in real time, the signals are transmitted to the monitoring console after A / D conversion, and the clamping force is linearly and positively related to the wire tension.

[0029] The wire 10 is connected between the wire clamping block 42 and the pressure sensor 43; the first handle 41 has a circular hole channel 48 radially penetrating through the middle part; the second handle 46 has a through channel 49 axially penetrating through; the second handle 46 is connected with a conical tube 47, and the conical tube 47 is communicated with the through channel 49; the wire discharged by the wire releasing mechanism 1 passes through the circular hole channel 48, the wire clamping block 42, the through channel 49 and the conical tube 47 in sequence, and the wire 10 discharged from the mouth of the conical tube 47 is woven into the stent by the wire winding nail 9. The micro pressure sensor 43 on the wire pen 4 is located on the wire clamping block 42 where the first handle 41 and the second handle 46 contact, and the pressure sensor 43 transmits the pressure of the first handle 41 and the second handle 46 on the wire 10 to the monitoring console 3. The detection mechanism 2 detects the apparent structure and wire winding curvature of the woven stent in real time, and is used for quality screening of the formed stent.

[0030] The connecting shaft 44 connects the end of the first handle 41 to the groove of the second handle 46, and the second handle 46 and the first handle 41 rotate axially with the connecting shaft 44 as the center; the two ends of the spring 45 are connected to the second handle 46 and the first handle 41 respectively, and are used for adjusting the tension of the wire 10; the conical tube 47 is installed at the bottom end of the second handle 46, and is on the same central axis as the through channel 49 on the second handle 46.

[0031] A six-axis attitude sensor can also be installed at the tail of the second handle 46 of the wire pen 4, with a sampling frequency of 100 Hz; a micro laser positioner is installed at the outlet of the conical tube 47, with a spot diameter of 0.5 mm, and is directed to the wire winding nail 9. The holding angle and height of the wire pen are detected in real time, and the laser positioning is used to ensure that the wire outlet is aligned with the wire winding nail 9.

[0032] The wire releasing mechanism 1 includes a tensioning mechanism 11, a wire releasing wheel 12 and a motor 13; the tensioning mechanism 11 is used for tensioning the wire 10, so that the wire 10 maintains appropriate tension. The mechanical output end of the motor 13 is connected to the wire releasing wheel 12 to drive the wire releasing wheel 12 to rotate, change direction or stop; the output end of the motor 13 is electrically connected to the monitoring console 3, and the tensioning mechanism 11 is also connected with a tension sensor for detecting the tension of the wire, and the tension sensor is electrically connected to the monitoring console 3. The monitoring console 3 compares the pressure received by the sensor with the set value to control the motor 13 to release the wire 10 or stop. The monitoring console 3 can realize two modes of automatic tension control and manual tension control, indirectly control the transmission mechanism of the automatic wire releasing mechanism 1, and facilitate the wire pen 4 to weave on the mold fixing block where the stent mold is placed.

[0033] Further improvement can also be made by installing a servo motor with torque controller beside the tensioning mechanism 11 of the wire releasing mechanism 1, which is coaxially connected with the wire releasing wheel 12; the motor controller is electrically connected to the monitoring console 3. In this way, the wire releasing speed can be adjusted in real time according to the trajectory deviation, such as reducing the speed when the trajectory deviates, to avoid wire accumulation.

[0034] To this end, the monitoring console 3 can be provided with a self-locking button. When the self-locking button is started, the monitoring console 3 is in automatic tension control mode, and the wire tension is controlled according to the set parameters; when the self-locking button is turned off, the monitoring console is in manual tension control mode, and the wire tension is adjusted by the clamping force of the first handle 41 and the second handle 46.

[0035] In the monitoring console (3), a wire drawing trajectory closed-loop control algorithm can also be integrated, and the steps are as follows:

[0036] Step 1. Trajectory preset: import the standard trajectory parameters of the support weaving such as the wire winding pitch, the wire winding angle, and the number of turns per coil through the control screen 32 to generate a digital trajectory model;

[0037] Step 2. Real-time acquisition: the camera 22 acquires 20 frames of support weaving images per second, combines the mold position recognized by the grating ruler, and the wire pen angle data detected by the posture sensor, and extracts the current actual trajectory;

[0038] Step 3. Deviation analysis: compare the "standard trajectory" with the "actual trajectory" to calculate the deviation value, such as X-axis deviation Δx, Y-axis deviation Δy, and angle deviation Δθ.

[0039] Step 4. Active adjustment: if the deviation is greater than the preset threshold (such as 0.1 mm), the monitoring console outputs a control signal:

[0040] Control the stepping motor of the mold fixing block to adjust the position and compensate Δx / Δy;

[0041] Control the servo motor of the wire drawing mechanism to adjust the wire drawing speed, and slow down when the deviation is large;

[0042] The control screen 32 displays a deviation prompt to guide the operator to adjust the wire pen posture.

[0043] The above algorithm can achieve a trajectory accuracy of ±0.05 mm through multi-sensor fusion, solving the problem of manual weaving trajectory deviation.

[0044] In the automatic tension mode, the target tension is set through the monitoring console 3, such as 0.5N; the tension sensor of the tensioning mechanism 11 detects the wire drawing tension in real time, and if the wire drawing tension is greater than the target value, the control motor 13 speeds up the wire drawing; if it is less than the target value, the wire drawing is slowed down; the pressure sensor 43 detects the clamping force of the wire 10, and if the clamping force corresponding to the tension and the wire drawing tension deviation is greater than 10%, the control screen prompts "calibrate clamping force".

[0045] In the manual tension mode, first, the tensioning mechanism is kept at a minimum tension such as 0.1-1 N to prevent the wire from relaxing; an operator holds the wire pen 4 to adjust the clamping force, and the pressure sensor 43 converts the clamping force into real-time tension and displays it on the control screen; if the tension exceeds the safety threshold of 1.5-2.5 N, the monitoring console issues an audible and visual alarm, and the tensioning mechanism automatically relaxes the wire.

[0046] The detection mechanism 2 includes a detection bracket 21 and a camera 22; one end of the detection bracket 21 is fixedly connected to the base 31, and the other end movably connects the camera 22; the camera 22 is electrically connected to the control screen 32, and the camera 22 transmits the captured pictures to the control screen 32 in real time for display and viewing.

[0047] In this embodiment, the second handle 46 and the first handle 41 are made of photosensitive resin as raw material and are prepared by using 3D printing technology. The wire pen 4 is designed to simulate ergonomics, and the holding part fits the structure of the hand, is not easy to slip off, and is convenient to hold and operate the wire pen weaving support.

[0048] The monitoring console 3 and the micro pressure sensor 43 can be connected and transmitted through Bluetooth. The Bluetooth connection method is used to reduce the wire connection between the wire pen 4 and other components as much as possible, and to avoid physical interference of the wire pen by other wires during work.

[0049] The support mold is planar or cylindrical, including a cylindrical support mold 7 and a flat plate support mold 8.

[0050] The mold fixing block can adapt to support molds of different sizes and shapes.

[0051] The first handle 41 and the second handle 46 are prepared by using 3D printing technology and are made of photosensitive resin as raw material. The first handle 41 and the second handle 46 both contain wave-shaped textures, which conform to the ergonomic design and are convenient for hand holding.

[0052] The conical tube 47 of the wire pen 4 is made of one or more of tungsten steel, stainless steel, and aluminum alloy. The inner diameter of the conical tube 47 is 1.1-2.0 times the wire diameter. The connection between the conical tube 47 and the first handle 41 is detachable, which is convenient for replacing conical tubes of different sizes. 1.1 times the wire diameter ensures smooth passage of the wire, avoiding wire jamming due to too small gap, especially for elastic nickel-titanium wire, which is easy to bend when the gap is too small; 2.0 times the wire diameter prevents the wire from shaking too much in the tube, ensuring the accuracy of the wire trajectory, and when the gap is too large, the wire is easy to deviate from the center of the conical tube outlet; for example, when the wire diameter is 0.2 mm, the inner diameter of the conical tube is selected to be 0.22-0.4 mm, preferably 0.3 mm, which takes into account the smoothness and stability.

[0053] The use method of the tension-controllable wire drawing device for weaving stents according to the present application comprises the following steps:

[0054] S1: Turn on the switch button of the monitoring console 3, input the operator's name, department, and date parameters for recording and archiving;

[0058] S5: When holding the wire drawing pen 4, the second handle 46 is located inside the thumb knuckle, and the first handle 41 is located inside the bend of the other four fingers;

[0059] S6: When using the wire drawing pen 4, the conical tube 47 is parallel to the wire winding peg 9 and perpendicular to the plane where the wire winding peg 9 is located;

[0060] S7: If the self-locking button is started, it is in automatic tension control mode, and the braiding on the support mold can be performed according to the parameters set in S2; if the self-locking button is turned off, it is in manual tension control mode, and the pay-off mode of the automatic pay-off wheel is that the clamping force and pulling force of the first handle and the second handle held by the hand form a clamping force and pulling force on the wire, when the hand is held tightly, the clamping surface of the wire clamping block increases the friction force on the wire, and the wire is pulled tightly; when the hand is held loosely, the spring's rebound force pulls open the clamping surface of the wire clamping block, and the wire is loosened, so as to adjust the tension and perform braiding on the support mold;

[0061] S8: The monitoring console displays the cumulative wire consumption, wire speed, and wire tension parameters in real time.
