DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0023] In the description of the present utility model, it should be understood that the terms "upper", "middle", "outer", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0024] Embodiment 1: A laparoscopic surgical suture needle, comprising: a needle body 1, a thread-passing hole 2 is provided on the needle body 1, a thread inlet groove 3 is provided on the side wall of the thread-passing hole 2, an elastic piece 4 is provided at one end of the thread inlet groove 3, and a receiving groove 5 for cooperating with the elastic piece 4 for closing is provided at the other end of the thread inlet groove 3. A cutting mechanism 6 is installed at one end of the thread-passing hole 2 close to the tip of the needle body 1. In this application, a thread-passing hole 2 is provided on the needle body 1, a thread inlet groove 3 is provided on the side wall of the thread-passing hole 2, an elastic piece 4 is provided at one end of the thread inlet groove 3, and a receiving groove 5 for cooperating with the elastic piece 4 for closing is provided at the other end of the thread inlet groove 3, so that when the operator uses it, the suture can be pressed against the elastic piece 4 to deform and enter the thread-passing hole 2 through the thread inlet groove 3, and the elastic piece 4 after rebounding can prevent the suture from falling off from the thread inlet groove 3, thereby improving the threading convenience and stability; by installing a cutting mechanism 6 at one end of the thread-passing hole 2 close to the tip of the needle body 1, when the operator needs to cut the suture, the needle body 1 can be pulled backward to cut the suture by the cutting mechanism 6, thus avoiding the operator from replacing tools for cutting, simplifying the operation steps, and further improving the surgical efficiency.
[0025] The elastic piece 4 can be made of hard and reboundable materials such as metal or plastic, etc., but the edge of the elastic piece 4 must be kept smooth to avoid cutting the suture too sharply.
[0026] Embodiment 2: On the basis of Embodiment 1, the cutting mechanism 6 is set as a V-shaped cutting knife 61. Only the lower edge blade of the V-shaped cutting knife 61 is sharp, and the upper edge of the V-shaped cutting knife 61 only plays a guiding role, and the suture contacting the upper edge of the V-shaped cutting knife 61 will not cause cutting. In this application, by setting the cutting mechanism 6 as a V-shaped cutting knife 61, accidental cutting of the suture during the operation is avoided, and thus the use stability is improved.
[0027] Embodiment 3: On the basis of Embodiment 2, the V-shaped cutting knife 61 includes: a knife body 611, a V-shaped cutting part 612 is provided on the knife body 611, and an inclined surface guiding part 613 for preventing accidental cutting is provided on the knife body 611. In this application, by providing a V-shaped cutting part 612 on the knife body 611 and an inclined surface guiding part 613 for preventing accidental cutting on the knife body 611, accidental cutting of the suture during misoperation in the surgical process is avoided, and thus the use error tolerance rate is improved.
[0028] Among them, when the inclined plane guiding part 613 is not needed for cutting, it can prevent the suture from contacting the V-shaped cutting part 612 and causing accidental cutting. And when the operator performs the cutting operation, the inclined plane guiding part 613 can guide the suture to move towards the V-shaped cutting part 612 through the inclined plane, improving the cutting efficiency.
[0029] Embodiment 4: On the basis of Embodiment 1, the cutting mechanism 6 is set as an arc cutting knife 62. In this application, by setting the cutting mechanism 6 as an arc cutting knife 62, the structural complexity of the arc cutting knife 62 is lower than that of the V-shaped cutting knife 61, reducing the manufacturing cost; and its shape fits the lower edge of the threading hole 2, making it difficult for the suture to contact the blade, thus avoiding accidental cutting of the suture during accidental operation in the surgical process and improving the use error tolerance rate.
[0030] Embodiment 5: On the basis of Embodiment 1, the cutting mechanism 6 is set as a straight cutting knife 63. In this application, by setting the cutting mechanism 6 as a straight cutting knife 63, the straight cutting knife 63 has a simple structure and is convenient for manufacturing, reducing the production cost.
[0031] Embodiment 6: On the basis of Embodiment 1, the needle body 1 includes a straight section 11. One end of the straight section 11 is connected to a bent section 12, and the threading hole 2 is arranged at the other end of the straight section 11. In this application, by connecting one end of the straight section 11 to the bent section 12 and arranging the threading hole 2 at the other end of the straight section 11, when only perforating the skin rather than suturing is required, it is convenient for the operator to perforate and pull out the needle, improving the use convenience.
[0032] Embodiment 7: On the basis of Embodiment 6, the straight section 11 and the bent section 12 are integrally formed. In this application, by integrally forming the straight section 11 and the bent section 12, the structural strength is improved, avoiding needle breakage during the surgical process, and thus reducing the medical risk.
[0033] Embodiment 8: On the basis of Embodiment 1, the outer side of the wire inlet groove 3 is set as an arc shape. In this application, by setting the outer side of the wire inlet groove 3 as an arc shape, it is convenient for the operator to place the suture in the wire inlet groove 3 when threading, improving the use convenience.
[0034] Working process:
[0035] When threading is required, first place the suture in the wire inlet groove 3. The elastic piece 4 deforms under the pressure of the suture and enters the threading hole 2. Subsequently, the elastic piece 4 rebounds and combines with the receiving groove 5 to close the threading hole 2 to prevent the suture from falling off; when cutting is required, pull the suture towards the V-shaped cutting knife 61. After the suture contacts the inclined plane guiding part 613, it is guided by the inclined plane to move towards the V-shaped cutting part 612. Finally, when the suture moves to the V-shaped sharp part of the V-shaped cutting part 612, the suture is cut.
