Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to an internal suture device for skin wounds. Background Art

[0002] Due to trauma and illness requiring surgery, a large number of skin wounds need to be sutured every day. In order to shorten the operation time, especially in emergency situations, doctors often use skin wound staplers (commonly known as skin staplers) to suture the wounds;

[0003] Although existing skin wound staplers can quickly close wounds, they can only perform full-thickness external sutures on the skin, and cannot perform internal sutures to reduce tension. After the staples are removed, the wound is prone to splitting and widening, and often leaves obvious scars in the later stages. These shortcomings greatly limit their use.

[0004] Although doctors can do internal sutures by hand to avoid wound splitting, widening, and leaving obvious scars later, this kind of manual suture is time-consuming and not suitable for surgeries that require "every second counts". Therefore, it is necessary to develop a skin wound internal suture device that can quickly complete wound suture and reduce tension by internal suture.

[0005] To this end, we propose a skin wound suture device. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a skin wound internal suture device, which can not only quickly complete the wound suturing, but also reduce the tension of the internal suture, thereby avoiding the wound from splitting and widening, and avoiding leaving obvious scars in the later stage.

[0007] The above technical objectives of the utility model are achieved through the following technical solutions:

[0008] An internal suture device for skin wounds, comprising a pair of internal suture arms rotatably connected at the top, a limit reset rod connected between the two internal suture arms, and a guide needle, wherein the internal suture arm comprises a needle bin, a needle pressing plate and a finger ring;

[0009] The needle bin comprises a needle pressing piece, a needle pushing plate, a needle pushing spring, a rotating shaft, and a base. The top ends of a pair of inner suturing arms are rotatably connected via a rotating shaft, the needle pushing plate is movably connected to the base, and the needle pushing spring is connected to the inner wall of the base.

[0010] By setting up a needle magazine, the bidirectional barbed internal suture is loaded into the guide needle row, which can be installed at the factory, or loaded by a nurse or assistant before use. The guide needle row with the internal suture is loaded into the needle magazine and pushed into place with a needle push plate.

[0011] Further, the needle pressing plate is rotatably connected to the base through a rotating shaft, and the needle pressing piece is fixedly connected to one end of the needle pressing plate away from the rotating shaft.

[0012] Further, the guiding needle is installed inside the base. Five of the guiding needles are glued together in a row, and the guiding needle is in a "U" shape.

[0013] Further, the guiding needle includes a solid outer skin section and a hollow skin-piercing section, and a double-sided barbed inner suture is arranged inside the hollow skin-piercing section.

[0014] Five guiding needles are glued together in a row. One end of the needle pressing plate is connected to the rotating shaft, and the needle pressing piece at the other end can press the guiding needle into the skin, so as to insert the double-sided barbed inner suture, playing a role in internal suture and fixing the wound.

[0015] Further, the limit and reset rod includes a limit rod and a reset spring. The limit rod is a telescopic rod. One end of the limit rod is fixedly connected to the left inner suture arm, and the telescopic end of the limit rod is fixedly connected to the right inner suture arm.

[0016] Further, a reset spring is movably connected to the outside of the limit rod, and both ends of the reset spring are fixedly connected to the left and right inner suture arms respectively.

[0017] Further, a reset elastic piece is connected between the needle cartridge and the needle pressing plate. One end of the reset elastic piece is fixedly connected to the needle cartridge, and the other end of the reset elastic piece is fixedly connected to the needle pressing plate.

[0018] Further, the finger ring includes a thumb finger ring and an index and middle finger ring. The left end of the left inner suture arm is fixedly connected to the thumb finger ring, and the right end of the right inner suture arm is fixedly connected to the index and middle finger ring.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. The utility model can not only quickly complete wound suture but also perform internal suture and tension reduction, thereby avoiding wound dehiscence and widening, and avoiding obvious scars left in the later stage;

[0021] 2. By providing a needle cartridge, the double-sided barbed inner suture is loaded into the row of guiding needles, which can be loaded at the factory or by a nurse or assistant before use. The row of guiding needles with the inner suture is loaded into the needle cartridge, and the row of guiding needles is pushed in place by the needle pushing plate;

[0022] 3. Five guiding needles are glued together in a row. One end of the needle pressing plate is connected to the rotating shaft, and the needle pressing piece at the other end can press the guiding needle into the skin, so as to insert the double-sided barbed inner suture, playing a role in internal suture and fixing the wound.
