[0004] Medical suture needles need to be punched after cutting and polishing. The punching position is the place where the surgical suture is connected, which is located at the tail of the medical suture needle. Using the current clamp, the medical suture needle is mostly clamped by double-sided clamping. Since the diameter of the medical suture needle is usually around four millimeters, the clamping force adjustment of the clamp is complicated. In addition, suture needles include two major categories: angle needles and round needles. The clamp that clamps on both sides is not suitable for clamping angle needles and needs to be configured separately, which is inconvenient. Therefore, a hole processing clamping mechanism is proposed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] See also Figure 1-3 In this embodiment, a hole processing clamping mechanism includes an electric drill 1 and a conveyor 2 located on one side of the electric drill 1. The electric drill 1 and the conveyor 2 are installed together on a device base for punching medical suture needles.

[0023] A clamping mechanism for hole processing also includes a transmission belt 3 installed on the conveyor 2 and a mounting plate 4 partially fixedly connected to the transmission belt 3.

[0024] Specifically, the conveyor 2 is a belt conveyor device for conveying medical suture needles.

[0025] In this embodiment, a baffle 5 is fixedly mounted on the mounting plate 4 , a clamp is provided on the mounting plate 4 , and a suture needle 15 passes through the clamp.

[0026] It should be noted that the clamp includes a mounting seat 6 fixed on the mounting plate 4, and the mounting seat 6 is attached to the baffle 5, wherein the interior of the mounting seat 6 is hollow, which can facilitate the passage of the suture needle 15.

[0027] The clamp further comprises a fixing tube 7 fixed on the mounting seat 6 , a jacket 10 built into the fixing tube 7 , and an adjusting bolt 12 for squeezing the jacket 10 .

[0028] In a specific implementation, the suture needle 15 is inserted from one end of the fixed tube 7 , passes through the jacket 10 and comes out from the other end of the mounting seat 6 , and then the jacket 10 is clamped on the suture needle 15 by rotating the adjusting bolt 12 .

[0029] In this embodiment, a connecting ring 9 is fixedly installed at the bottom of the jacket 10 , and the connecting ring 9 is fixed to the bottom end of the fixed tube 7 , so that the jacket 10 is located in the middle of the fixed tube 7 .

[0030] In this embodiment, a groove 8 is recessed on the outer wall of the fixing tube 7 , and the mounting seat 6 is embedded in the groove 8 , so that the installation stability of the fixing tube 7 relative to the mounting seat 6 is improved.

[0031] It should be noted that a thread groove 11 is provided on the top end of the fixing tube 7, and a thread tooth 13 is provided on the bottom end of the adjusting bolt 12. The thread tooth 13 is threadedly connected to the thread groove 11. Through the engagement of the thread tooth 13, the adjusting bolt 12 can extend toward the inside of the fixing tube 7 when rotating.

[0032] The jacket 10 in this embodiment is divided into three petals and fixed on the connecting ring 9. Under the influence of the flexibility of the jacket 10 itself, the jacket 10 can be opened and closed relative to the connecting ring 9 to complete the clamping of suture needles 15 of different sizes.

[0033] In this embodiment, a trapezoidal groove 14 is formed at the lower end of the adjusting bolt 12 , and the trapezoidal groove 14 fits the upper end of the jacket 10 , and can be moved downward by the adjusting bolt 12 , thereby squeezing the jacket 10 for clamping.

[0034] The top of the jacket 10 extends outward in a truncated cone shape, and the top of the jacket 10 fits in the trapezoidal groove 14 .

[0035] In this way, the clamping can be performed by simply rotating the adjusting bolt 12 so that the adjusting bolt 12 presses the clamping sleeve 10 .

[0036] Since there are at least three jackets 10, the three jackets 10 can better adapt to the clamping of the corner needles, thereby improving the adaptability of the clamping.

[0037] In addition, there are several mounting plates 4, and the several mounting plates 4 are connected by connecting bridges 16, so that several suture needles 15 can be continuously transported.

[0038] The working principle of the above embodiment is:

[0039] By inserting the suture needle 15 from the fixed tube 7 on one side of the mounting plate 4, the suture needle 15 is passed through the fixed tube 7 from the adjusting bolt 12 threadedly mounted on the upper end of the fixed tube 7, and then the suture needle 15 continuously passes through the middle of the jacket 10 in the fixed tube 7, so that the suture needle 15 passes through the mounting seat 6. At this time, by rotating the adjusting bolt 12, the threaded teeth 13 at the end of the adjusting bolt 12 are threadedly engaged with the thread groove 11 at the top of the fixed tube 7, so that the adjusting bolt 12 extends relative to the fixed tube 7, and the trapezoidal groove 14 at the end of the adjusting bolt 12 is pressed on the jacket 10 through contact. At this time, the jacket 10 is subjected to a radial force to be clamped toward the middle, so that the suture needle 15 passing through the jacket 10 is clamped to complete the clamping.
