[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3This utility model provides a technical solution: a rotating self-fixing needle holder with marking, including a needle holder body 1, a handle positioning seat 11 on the needle holder body 1, and handle rods 12 rotatably connected to both sides of the handle positioning seat 11, with a handle ring 2 integrally provided on the handle rods 12. The needle holder body 1 also has a needle rod positioning seat 6, with symmetrically arranged needle rods 4 rotatably connected to the side of the needle rod positioning seat 6. The handle rods 12 are inclined at 135° relative to the axis of the clamping adjustment sleeve 5, and each of the handle rods 12 is integrally provided with a first fastening tooth 9 that engages with each other. This structure, through the inclined arrangement of the handle rods 12, makes it easier to hold and operate the needle holder body 1, facilitating suturing operations. The other end of the needle rods 4 is coated with... The end marking 3 and the needle holding rods 4 are connected by a spring-loaded opening member 10 near the end marking 3. A clamping adjustment sleeve 5 is fitted around the outside of the needle holding rods 4, and a rotating adjustment seat 7 is fitted around the outside of the clamping adjustment sleeve 5. The clamping adjustment sleeve 5 is movably connected to the handle positioning seat 11, and a clamping drive mechanism 8 is installed between the end of the clamping adjustment sleeve 5 and the handle rod 12. The clamping drive mechanism 8 and the handle rod 12 are rotatably connected via a connecting rod. This structure allows the needle holder body 1 to be held by the handle ring 2, and the handle rod 12 to move relative to the handle positioning seat 11 by finger control. Under the action of the clamping drive mechanism 8, the clamping adjustment sleeve 5 can move linearly relative to the handle positioning seat 11, thus achieving the connection between the clamping adjustment sleeve 5 and the needle holding rod. The relative movement of rods 4 controls the angle between the needle-holding rods 4, allowing the needle-holding rods 4 to clamp and fix the needle via the end marking 3. The needle-holding rod positioning seat 6 is rotatably engaged within the clamping adjusting sleeve 5, and the needle-holding rod 4 contacts and engages with the clamping adjusting sleeve 5. This structure allows the needle-holding rod positioning seat 6 to rotate under the positioning of the clamping adjusting sleeve 5. The clamping adjusting sleeve 5 and the connecting seat 14 mutually limit each other, ensuring that the connecting seat 14 secures the needle-holding rod positioning seat 6 and the rotating adjusting seat 7, achieving synchronous rotation of the connecting seat 14, the needle-holding rod positioning seat 6, and the rotating adjusting seat 7. The clamping adjusting sleeve 5 restricts the range of motion through the connecting seat 14, and the rotating adjusting seat 7 is engaged with the needle-holding rod positioning seat 6. A connecting seat 14 is inserted and fixed between the seats 6, and a through hole is opened on the side of the clamping adjusting sleeve 5 to engage with the connecting seat 14. The width of the through hole of the clamping adjusting sleeve 5 is greater than the diameter of the connecting seat 14. The rotating adjusting seat 7 is a ring structure, and the rotating adjusting seat 7 is rotatably engaged with the handle positioning seat 11. This structure allows the handle positioning seat 11 to rotate and install the rotating adjusting seat 7. When the rotating adjusting seat 7 is rotated, the rotating adjusting seat 7 only performs circumferential motion. The outer ring of the rotating adjusting seat 7 is integrally provided with a second fastening tooth 13, and the second fastening tooth 13 is tightly engaged with the handle positioning seat 11. This structure allows the rotating adjusting seat 7 to be locked relative to the handle positioning seat 11 through the second fastening tooth 13 during rotation.

[0016] Working principle: When using this rotating self-fixing needle holder with marking, the operator first holds the needle holder body 1 and positions their fingers using the handle ring 2. Then, the operator controls the opening and closing of the handle rod 12 with their fingers. Under the positioning of the handle positioning seat 11, the handle rod 12 drives the clamping drive mechanism 8 to move, thereby realizing the movement of the clamping adjustment sleeve 5. The handle rod 12 is tilted at 135° relative to the handle positioning seat 11, which is a more suitable angle. The clamping adjustment sleeve 5 adjusts the opening angle of the needle holder rod 4 through its movement. The needle holder rod 4 rotates under the positioning of the needle holder rod positioning seat 6. The needle is clamped by the spring-supported part 10. The handle rods 12 are clamped together by the first fastening teeth 9. The end mark 3 can be used as a reference to determine the angle between the needle holding rod 4 and the needle. When it is necessary to adjust the angle between the needle and the handle rod 12, the rotating adjustment seat 7 drives the needle holding rod positioning seat 6 to rotate relative to the handle positioning seat 11. During the rotation, the needle holding rod positioning seat 6 is locked synchronously by the second fastening teeth 13. This is beneficial for suturing tissues in different positions, reducing the difficulty of suturing, and thus completing a series of tasks.

[0017] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
