Description

Technical Field

[0001] The invention relates to the technical field of needle holding pliers processing, in particular to a device for synchronously processing tooth patterns of needle holding pliers. Background Art

[0002] Needle holders are core instruments used to clamp suture needles in surgical and microsurgical operations. They are made of medical stainless steel. The tooth surfaces on the left and right handles of the needle holders are staggered and complementary, which makes it easy to apply stable clamping force to the suture needle.

[0003] When currently producing and processing needle holders, the teeth on both sides of the needle holders are usually processed separately in standard batches, and then they are assembled into an integrated unit. However, during the process of separate processing of the tooth surface of the needle holder, if the limit clamping or laser engraving of the pliers has an angle deviation, it will cause a slight deviation in the tooth processing on the tooth surface. When the left and right pliers handles are assembled together, the teeth on the tooth surface of the left and right pliers handles are matched, and there are slight gaps between the local teeth or mutual wear between the teeth, which makes the needle holder poor in clamping the suture needle, affecting the service life of the needle holder. In addition, during the use of the needle holder, the tooth surface is usually stained with tissue fluid or blood, which affects the clamping friction between the needle holder and the suture needle. The current conventional tensile disengagement test after clamping the needle holder cannot meet the actual use of the needle holder, making the test data inaccurate. Therefore, a synchronous processing device for the tooth pattern of a needle holder is proposed. Summary of the Invention

[0010] Preferably, the gear adjustment assembly consists of an adjustment rack and an adjustment gear, the adjustment rack is meshed with the adjustment gear, the mobile platform is fixedly connected to the two adjustment racks respectively, and the adjustment gear is rotationally connected to the assembly vertical frame through a rotating shaft.

[0016] 3. This solution uses a parallelogram structure with two horizontal and two vertical assembly frames, which can utilize two laser processing seats to operate simultaneously, thereby significantly improving processing efficiency and ensuring processing consistency.

During this process, the steering motor 7 on one side drives the clamp handle 13 on one side to rotate 180 degrees, so that the toothed surfaces of the two clamp handles 13 are in a state of facing each other. After the two clamp handles 13 are docked, they will be in the state of assembled needle holders (such as Figure 7 shown); Based on the above advantages, the self-adjusting slider 10 is controlled to slide in the control guide groove of the simulation disk 9, and the self-adjusting slider 10 drives the finger grip portion of the pliers handle 13 to move in an arc through the limit column 11, simulating the movement of the needle holder when in use, so that the two tooth surface patterns are opened, which is convenient for subsequent inspection of the processed tooth surface; The processing table 1 is slidably provided with a movable control seat 3, and the movable control seat 3 is connected to a movable module via a fixed plate 15. The movable module is connected to two symmetrically arranged tooth adjustment components for adjusting the offset angle of the assembly frame; Furthermore, the mobile module includes two synchronization seats 16 respectively fixed on the two assembly horizontal frames 4 below, the mobile control seat 3 is fixedly connected to the synchronization seat 16 through the fixed plate 15, the two synchronization seats 16 are fixedly connected through the mobile platform 17, the mobile platform 17 is fixedly connected to the detection frame 20, the gear adjustment assembly consists of an adjustment rack 18 and an adjustment gear 19, the adjustment rack 18 is meshed with the adjustment gear 19, the mobile platform 17 is fixedly connected to the two adjustment racks 18, and the adjustment gear 19 is rotatably connected to the assembly vertical frame 5 through a rotating shaft; It should be noted that: the left and right sets of clamp handles 13 to be processed with tooth patterns are placed on the two simulation disks 9 respectively, the gripping part of the clamp handle 13 is limited to the limiting column 11 on the self-adjusting slider 10, and the shaft hole part of the rotating part of the clamp handle 13 is limited to the limiting shaft seat 12. The limiting column 11 and the limiting shaft seat 12 are assisted by magnetic material for limiting. During the limiting process of the two clamp handles 13, the tooth pattern surfaces to be processed are set downward, and then the two laser processing seats 14 below are used for synchronous processing. During the installation and processing of the clamp handle 13, In the process, the movement of the movable control seat 3 on the processing table 1 drives the synchronous seat 16 and the movable platform 17 to move together. The movement of the movable platform 17 drives the two adjustment racks 18 to move synchronously. The movement of the adjustment rack 18 drives the two adjustment gears 19 to rotate synchronously. The two adjustment gears 19 rotate synchronously in the same direction, which drives the two assembly vertical frames 5 to deflect synchronously in the same direction. As a result, the parallelogram formed by the two assembly horizontal frames 4 and the two assembly vertical frames 5 maintains synchronous and unidirectional offset, so that the two upper assembly horizontal frames 4 maintain synchronous displacement feed. The above advantages are: ensuring that the two clamp handles 13 maintain synchronous movement and angular offset during the processing, achieving synchronous tooth pattern processing of the two combined clamp handles 13, and avoiding tooth offset during tooth pattern processing; The mobile module is provided with a detection frame 20, and two symmetrically arranged hydraulic push rods 22 are provided in the detection frame 20. One side of the hydraulic push rod 22 is connected to the suture needle 24 through the magnetic limit seat 23, and the other side of the hydraulic push rod 22 is connected to the simulated tissue membrane 27 through the detection seat 25. A deflection detection component is provided below the simulated tissue to detect whether the suture needle 24 deviates after passing through the simulated tissue membrane 27; Furthermore, a notch is provided on the detection frame 20, and a spray module 21 is fixedly connected to the inner wall opposite to the notch on the detection frame 20, which is used to spray liquid on the teeth of the pliers handle 13, and a limiting arc groove adapted to the suture needle 24 is provided on the magnetic limit seat 23. A unwinding roller mechanism 26 fixed on the inner wall of the detection frame 20 is provided below the detection seat 25, and a winding roller mechanism 28 is fixedly connected to the inner end face of the detection frame 20. The two ends of the simulated tissue membrane 27 are respectively wound on the unwinding roller mechanism 26 and the winding roller mechanism 28. The inner wall of the detection seat 25 is fixedly connected to two horizontal shafts for supporting the simulated tissue membrane 27, and the shaft of the winding roller mechanism 28 is provided with a torsion spring. The deflection measurement component includes a horizontal seat 29 fixed on the inner wall of the detection seat 25, and the top of the horizontal seat 29 is fixedly connected to a pressure touch panel 30, and the outer wall of the pressure touch panel 30 is fixedly connected to an elastic diaphragm 31, and a corresponding photoelectric sensor 32 is provided below the elastic diaphragm 31.

[0023] It should be noted that: the movable platform 17 is moved in the direction opposite to the notch of the detection frame 20, so that the upper assembly cross frame 4 is moved down, and then the clamping ends of the two clamp handles 13 are moved down into the notch of the detection frame 20. After the two clamp handles 13 are simulated and assembled, the two tooth surfaces are opened, and then the spray module 21 is allowed to spray liquid on the two tooth surfaces to simulate the state in which the tooth surfaces are stained with tissue fluid or blood during the use of the needle holder, and to simulate the wet friction state in the process of clamping the suture needle 24. Then, the hydraulic push rod 22 is used to push the magnetic limit seat 23 to move, so that the tooth surface of the clamp handle 13 clamps the suture needle 24 near the tail, and then the hydraulic push rod 22 on the other side pushes the detection seat 25 to move. During the movement, the simulated tissue membrane 27 on the unwinding roller mechanism 26 will be pulled, and then the steering motor is used 7 drives the suture needle 24 to deflect downward, allowing the arc-shaped suture needle 24 to penetrate into the simulated tissue membrane 27. The resistance to the penetration of the suture needle 24 is limited and the simulated tissue membrane 27 will not be pulled. During the subsequent reset, the reeling roller mechanism 28 will reel up the excess simulated tissue membrane 27 through the rotation of the torsion spring, so as to facilitate the next detection as a new simulated tissue membrane 27. If, during the penetration process, the resistance of the simulated tissue membrane 27 to the suture needle 24 causes the suture needle 24 to deflect during the clamping process of the needle holder, the landing point of the suture needle 24 on the pressure touch panel 30 will deflect. The pressure touch panel 30 is covered with a puncture-proof film. If a large deviation occurs, the suture needle 24 will squeeze the elastic membrane 31 at the edge, so that the corresponding photoelectric sensor 32 detects the deformation displacement of the elastic membrane 31. The above benefits are as follows: it is easy to detect the degree of deviation of the suture needle 24 when piercing the simulated tissue membrane 27, and to detect the clamping strength of the processed tooth surfaces of the two clamp handles 13 on the suture needle 24 under wet friction conditions, thereby ensuring the quality of the processed tooth surfaces, and also facilitating the subsequent direct assembly of the two clamp handles 13 that have synchronously processed tooth surfaces; When the present invention is in use, the left and right sets of clamp handles 13 to be processed with tooth patterns are placed on two simulation disks 9 respectively, the gripping part of the clamp handle 13 is limited to the limiting column 11 on the self-adjusting slider 10, and the shaft hole part of the rotating part of the clamp handle 13 is limited to the limiting shaft seat 12. The limiting column 11 and the limiting shaft seat 12 are auxiliary limited by magnetic material. During the limiting process of the two clamp handles 13, the tooth pattern surfaces to be processed are set downward, and then the two laser processing seats 14 below are used for synchronous processing. During the installation process of the clamp handle 13 and the processing process, the movement of the mobile control seat 3 on the processing table 1 is used to drive the synchronous seat 16 and the mobile platform 1 7 moves together, the movement of the mobile platform 17 will drive the two adjustment racks 18 to move synchronously, the movement of the adjustment rack 18 will drive the two adjustment gears 19 to rotate synchronously, the two adjustment gears 19 rotate synchronously in the same direction, which will drive the two assembly vertical frames 5 to deflect synchronously in the same direction, thereby making the parallelogram composed of the two assembly horizontal frames 4 and the two assembly vertical frames 5 maintain synchronous and unidirectional offset, so that the two upper assembly horizontal frames 4 maintain synchronous displacement feed, thereby ensuring that the two clamp handles 13 maintain synchronous movement and angular offset during the processing process, so that the tooth pattern processing of the two combined clamp handles 13 is carried out synchronously, and the tooth offset during the tooth pattern processing is avoided; After the tooth pattern processing on the two clamp handles 13 is completed, the two electric push rods 8 are controlled to push the two clamp handles 13 to move relative to each other, so that the two clamp handles 13 are fitted together. During this process, the steering motor 7 on one side drives the clamp handle 13 on one side to rotate 180 degrees, so that the tooth pattern surfaces of the two clamp handles 13 are in a state of facing each other. After the two clamp handles 13 are connected, they will be in the state of assembled needle holders (such as Figure 7 As shown), the self-adjusting slider 10 is then controlled to slide in the control guide groove of the simulation disk 9. The self-adjusting slider 10 will drive the finger grip portion of the clamp handle 13 to move in an arc through the limit column 11, simulating the movement of the needle holder when in use, so that the two tooth surface patterns are opened, which is convenient for subsequent inspection of the processed tooth surface; During the inspection, the movable platform 17 is moved in the direction opposite to the notch of the inspection frame 20, so that the upper assembly cross frame 4 moves down, and then the clamping ends of the two clamp handles 13 move down into the notch of the inspection frame 20. After the two clamp handles 13 are simulated and assembled, the two tooth surfaces are opened, and then the spray module 21 is allowed to spray liquid on the two tooth surfaces to simulate the state in which the tooth surfaces are stained with tissue fluid or blood during the use of the needle holder, and simulate the wet friction state in the process of clamping the suture needle 24. Then, the hydraulic push rod 22 is used to push the magnetic limit seat 23 to move, so that the tooth surface of the clamp handle 13 clamps the suture needle 24 near the tail, and then the hydraulic push rod 22 on the other side pushes the inspection seat 25 to move. During the movement, the simulated tissue membrane 27 on the unwinding roller mechanism 26 will be pulled, and then the steering motor 7 is used to drive the suture needle 24 to deflect downward, so that the arc-shaped suture needle 24 penetrates into the simulated tissue membrane 27. The resistance of the suture needle 24 to penetration is limited and will not cause any damage. The simulated tissue membrane 27 is pulled, and when it is subsequently reset, the winding roller mechanism 28 will rewind the excess simulated tissue membrane 27 through the rotation of the torsion spring, so that it is easy to detect as a new simulated tissue membrane 27 next time. If the simulated tissue membrane 27 resists the suture needle 24 during the insertion process, causing the suture needle 24 to deviate from the landing position on the pressure touch panel 30. The pressure touch panel 30 is covered with a puncture-proof film. If a large deviation occurs, the suture needle 24 will squeeze the elastic diaphragm 31 at the edge, so that the corresponding photoelectric sensor 32 detects the deformation displacement of the elastic diaphragm 31, and then detects the degree of deviation of the suture needle 24 when piercing the simulated tissue membrane 27, and detects the clamping strength of the two clamp handles 13 processing tooth surfaces to the suture needle 24 under wet friction state, to ensure the qualification of the processed tooth surfaces, and also facilitates the subsequent direct assembly of the two clamp handles 13 for synchronously processing tooth surfaces.
