Description

Technical Field

[0001] The utility model relates to the field of processing and manufacturing of medical appliances, and particularly relates to an auxiliary assembly tooling. Background Technique

[0002] A suture needle is a tool used for surgical suturing. The tail part of the needle is hollow for threading a suture line, and then the tail part of the needle is squeezed so that the tail part of the needle is pressed together with the suture line.

[0003] In the prior art, the utility model patent with the application number CN212466072U discloses a suture needle extrusion forging mechanism. Two vertical plates are arranged on a bottom plate perpendicularly. An fixing plate is arranged above the vertical plates. A forging cylinder is arranged below the bottom plate. The output end of the forging cylinder is provided with a floating joint. Two power rods are hinged on the floating joint. The other ends of the power rods are fixed with a push rod seat. A push rod is arranged in the push rod seat. It is characterized in that two cutter head slide ways are arranged side by side on the fixing plate. Cutter heads are slidably arranged in the cutter head slide ways. The two cutter heads are arranged oppositely. The two push rods are respectively arranged at the rear ends of the two cutter heads. A leaf spring is also arranged on the fixing plate and is matched with the rear ends of the cutter heads. When in use, the suture needle to be extruded and forged is placed between two notch openings. The forging cylinder drives the floating joint to retract, so that the two push rod seats move inwards. The push rods push the cutter heads to act through a stop rod. The two cutter heads move closer to each other to squeeze the suture needle and the suture line tightly. It does not require manual operation and is practical and convenient.

[0004] However, the above suture needle extrusion forging mechanism does not have a structure for fixing and supporting the suture needle. During the use process, it is necessary for an operator to hold the suture needle by hand and keep the tail end of the suture needle between the two cutter heads. When the two cutter heads move closer to each other to squeeze the suture needle, it is easy to cause the suture needle to accidentally slip out of the hand and even stab the operator, which needs to be improved.

[0022] As Figures 1 to 4As shown in the figure, an auxiliary assembly tooling includes a base 1. A vertical plate 2 is fixedly installed on the top of the base 1 through bolts. A pressing mechanism for pressing the tail end of a suture needle is provided on the vertical plate 2. Specifically, a notch 3 is provided on the front side of the vertical plate 2. The pressing mechanism includes a first movable plate 4 vertically slidably installed on the vertical plate 2. A through hole 5 is provided at the top of the vertical plate 2 and communicates downward with the top wall of the notch 3. The first movable plate 4 is slidably installed in the through hole 5. A top punch 6 located in the notch 3 is fixedly installed at the lower end of the first movable plate 4 through bolts. A second movable plate 7 is also vertically slidably installed on the vertical plate 2. A vertical sliding cavity 8 is provided in the vertical plate 2 behind the through hole 5. The upper end of the sliding cavity 8 penetrates upward through the top of the vertical plate 2. The second movable plate 7 is slidably installed in the sliding cavity 8. An installation portion 9 extending forward is integrally formed at the lower end of the second movable plate 7. An activity cavity 10 extending forward is provided at the position corresponding to the lower end of the sliding cavity 8 and the installation portion 9. The activity cavity 10 communicates with the bottom of the notch 3. When the second movable plate 7 moves up and down along the sliding cavity 8, it can drive the installation portion 9 to move up and down in the activity cavity 10. The top of the front end of the installation portion 9 extends into the notch 3 and a bottom punch 11 is fixedly installed through bolts. The bottom punch 11 is located directly below the top punch 6.

[0023] When assembling the suture needle and the suture thread, first insert the suture thread into the tail end of the suture needle, and then place the tail end of the suture needle between the top punch 6 and the bottom punch 11. By moving the top punch 6 downward, while the top punch 6 moves downward, the bottom punch 11 moves upward. The tail end of the suture needle is pressed by the top punch 6 and the bottom punch 11 to press the suture thread and the suture needle together.

[0024] A linkage mechanism for driving the first movable plate 4 and the second movable plate 7 to move in opposite directions is provided in the base 1. Specifically, as Figure 2 and Figure 3 shown, an installation cavity 12 is provided in the vertical plate 2 between the through hole 5 and the sliding cavity 8. A gear 13 is provided in the installation cavity 12. The gear 13 is rotatably installed between the left and right side walls of the installation cavity 12 through a horizontally extending rotating shaft 14. Vertically extending racks 15 are integrally formed on the rear side of the first movable plate 4 and the front side of the second movable plate 7 respectively. Both racks 15 extend into the installation cavity 12, and the two racks 15 are respectively engaged on the opposite sides of the gear 13, so that the moving directions of the first movable plate 4 and the second movable plate 7 are opposite.

[0025] The first movable plate 4 is driven by a power device to move downward; the upper ends of the first movable plate 4 and the second movable plate 7 both extend out of the top of the vertical plate 2. A horizontally extending top plate 16 is fixedly installed at the upper end of the first movable plate 4 through bolts. One end of the top plate 16 extends backward above the second movable plate 7. A vertically extending support spring 17 is fixedly installed between the bottom of the rear end of the top plate 16 and the second movable plate 7 through bolts. When there is no external force, the thrust of the support spring 17 drives the first movable plate 4 and the second movable plate 7 to move upward and downward respectively. Further, the first movable plate 4 and the second movable plate 7 drive the upper punch 6 and the lower punch 11 to move away from each other. At this time, the tail end of the suture needle can be placed between the upper punch 6 and the lower punch 11; a power device is arranged on the top of the first movable plate 4. The power device can be a cylinder. By applying pressure downward through the power device on the top plate 16 at the top of the first movable plate 4 and driving the first movable plate 4 to move downward, further, the first movable plate 4 drives the upper punch 6 to move downward. At the same time, the first movable plate 4 drives the second movable plate 7 to move upward through the gear 13, and the second movable plate 7 drives the lower punch 11 to move upward. The suture thread and the suture needle are pressed together by the upper punch 6 and the lower punch 11. After one pressing is completed, the pressure applied by the power device to the first movable plate 4 is removed. Further, driven by the support spring 17, the upper punch 6 and the lower punch 11 move in opposite directions respectively to return to their original positions, so as to perform the next pressing operation.

[0026] As Figure 1 and Figure 4 shown, a support plate 18 is fixedly installed on the vertical plate 2 on the right side of the pressing mechanism through bolts. A positioning groove 19 matching the suture needle is provided at the top of the support plate 18. The cross-section of the positioning groove 19 is arc-shaped. In this embodiment, the length direction of the positioning groove 19 extends linearly for matching a straight suture needle, or the length direction of the positioning groove 19 extends in an arc for matching an arc-shaped suture needle. The shape of the positioning groove 19 can be set according to the specific shape of the suture needle; a vertically penetrating guide hole 28 is provided on the support plate 18. A movable plate 20 is slidably installed in the guide hole 28. A pressing plate 21 is fixedly installed at the upper end of the movable plate 20 through bolts. A fixing groove 22 matching the suture needle is provided at the bottom of the front end of the pressing plate 21. The fixing groove 22 and the positioning groove 19 are symmetrically arranged up and down. When the pressing mechanism squeezes the suture needle, the suture needle is clamped by the positioning groove 19 and the fixing groove 22.

[0027] A return spring 23 for pushing the movable plate 20 to move upward is connected between the support plate 18 and the movable plate 20. A groove 24 is provided on the horizontal side of the movable plate 20. A support block 25 extending into the groove 24 is integrally formed on the inner wall of the guide hole 28. The two ends of the return spring 23 respectively abut against the support block 25 and the top wall of the groove 24. When there is no external force, the return spring 23 pushes the movable plate 20 upward and separates the pressing plate 21 from the support plate 18 upward, so as to place the suture needle to be pressed on the top of the support plate 18.

[0028] The lower end of the movable plate 20 extends out of the bottom of the support plate 18 and is fixedly installed with a metal plate 26 through bolts. An electromagnet 27 for adsorbing the metal plate 26 is fixedly installed on the base 1 below the metal plate 26 through bolts.

[0029] After inserting the suture into the tail end of the suture needle, place the suture needle in the positioning groove 19 on the top of the support plate 18, and make the tail end of the suture needle extend between the upper punch 6 and the lower punch 11. Then, energize the electromagnet 27. The electromagnet 27 adsorbs the metal plate 26 and drives the movable plate 20 to move downward along the guide hole 28. Further, the movable plate 20 drives the pressing plate 21 to fit downward on the top of the support plate 18, so that the suture needle is clamped between the positioning groove 19 and the fixing groove 22. When the upper punch 6 and the lower punch 11 squeeze the suture needle, there is no need for staff to support the suture needle, and the operation is safer.
