Problems solved by technology

There are the following deficiencies: ①The pinhole of the suture needle is very small, and the thick suture often cannot pass through the small suture needle hole; ②When the tip of the suture is forked, it is difficult to penetrate the needle hole; ③The operator or nurse is required to have Good eyesight and hand-eye coordination are required to thread needles accurately and quickly
Common suture needles take a long time to thread, which is time-consuming and labor-intensive, which affects the progress of the operation

Embodiment Construction

[0015] Such as figure 1 , figure 2 As shown, a non-piercing medical suture needle includes a curved needle body 1 with a sharp end at one end and a needle hole 2 at the other end.

[0016] Such as figure 2 , image 3 as shown, figure 2 It is the magnified plan view of pin tail 2; image 3 It is an enlarged plan view of pin tail 2. The needle hole 3 of the suture thread is formed by two interactive surfaces 5 at the needle tail, and the two mutual surfaces 5 are inside the needle tail 2 . The suture thread passes through the needle hole 3 to form a U-shaped groove 6 at the end of the needle. The upper end of the U-shaped groove 6 is open, and the left and right ends respectively have two surfaces extending inward. The bottom surface of shaped groove 6 forms oval line hole 4. There is a gap 9 between the two interaction surfaces 5, and the gap 9 is smaller than or equal to the thread diameter.

[0017] The upper side of the two interaction surfaces 5 forms a downwardl...

Abstract

The invention relates to a threading-free medical suture needle, which is an instrument for suture in a surgical operation process. The threading-free medical suture needle comprises a bent needle body (1), and is characterized in that one end of the bent needle body (1) is sharp, a groove (6) is formed at the other end of the bent needle body (1), an opening is arranged at the upper end of the U-shaped groove (6), two surfaces which inwards extend are respectively arranged at the left end and the right end of the U-shaped groove (6) and are mutually parallel, and a gap is formed between the two mutually parallel surfaces (5), and is smaller than or equal to a threading diameter. The threading-free medical suture needle is fast in operation, and can greatly saves threading time, a doctor using the suture needle does not need good vision and hand and eye coordination ability, so that the speed of surgery is increased, and sufferings of patients is relieved.

Description

technical field [0001] The invention belongs to medical instruments, in particular to a non-piercing medical suture needle, which is an instrument used for suturing during surgical operations. Background technique [0002] The suture needle is one of the indispensable instruments in the surgical operation process. At present, the pinhole of the suture needle commonly used in China is a rectangular pinhole. When using it, the surgeon or nurse needs to pass the suture thread through the pinhole, turn back the thread, and turn it back. The thread card can only be used after it is fixed on the needle holder. There are the following deficiencies: ①The pinhole of the suture needle is very small, and the thick suture often cannot pass through the small suture needle hole; ②When the tip of the suture is forked, it is difficult to penetrate the needle hole; ③The operator or nurse is required to have Good eyesight and hand-eye coordination are required to thread the needle accuratel...
