Description

Technical Field

[0001] The invention relates to the technical field of suturing devices, and in particular to a suturing device for emergency wound care. Background Art

[0002] Wound suturing is the process of aligning or reconstructing the channels of tissues and organs that have been cut or broken by trauma to restore their functions. It is a basic condition for ensuring good healing and is also one of the important basic surgical operation techniques. Unlike surgical incisions, in some accidents, patients' skin is often torn. Before suturing the torn wound, in order to achieve the best suturing effect and aesthetics, the skin at the wound needs to be aligned and closed first. This process currently requires medical staff to hold needle forceps to complete, which is difficult to operate and inconvenient for suturing operations.

[0003] The Chinese invention patent with patent number CN103271749B discloses a disposable skin stapler, including a housing, a handle and a staple storage box, wherein the rear end of the staple storage box is connected to the handle, and the staple storage box is fixedly mounted on the housing. The stapler can promptly push out the staples that have been sutured to avoid the staple jam phenomenon, making the surgical skin suture easier and smoother. However, the cost of the staples is high, while the cost of the suture thread is low. It is obvious that there is a waste of using a large number of staples at one time. Based on this, it is urgent to propose a suture device for emergency wound care. Summary of the invention

The three first gears 2 are respectively located at the left and right ends and the upper end of the inner ring of the suture needle 4. Under the limiting action of the three first gears 2, the suture needle 4 can rotate in the annular cavity 11. When the motor 7 is started, the motor 7 can drive the three second gears 6 to rotate through the third gear 14. The rotation of the three second gears 6 can drive the three first gears 2 to rotate through the rotating rod 5. Finally, each first gear 2 can drive the suture needle 4 to rotate by meshing with the arc-shaped tooth groove 3.

[0028] See also Figure 2 and Figure 5 The wire storage device includes a wire storage box 9, the outer side wall of the right end of the wire storage box 9 is provided with an external thread, the left end of the fixed cylinder 8 is provided with a threaded opening 19, the threaded opening 19 is connected to the annular cavity 11, the external thread is threadedly connected to the threaded opening 19, and a wire reel 1 is also rotatably connected to the left inner wall of the wire storage box 9.

[0029] See also Figure 4 One end of the suture needle 4 is provided with a needle head 18 with a conical structure, and the other end of the suture needle 4 away from the needle head 18 is provided with a through hole 17.

Before suturing the wound, the suture thread wound on the thread drum 1 can be first connected to the through hole 17 of the suture needle 4, and then the thread storage box 9 can be spirally screwed on the threaded opening 19 at one end of the fixed cylinder 8 to complete the thread supply of the suture needle 4.

[0031] See also Figure 1 A handle 16 is fixedly connected to the side wall of the fixed tube 8 , and a button 15 is also provided on the side wall of the fixed tube 8 .

[0032] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The button 15 is electrically connected to the motor 7, and is used to control the start and stop of the motor 7 and the direction of rotation. When the button 15 is pressed, the motor 7 drives the suture needle 4 to rotate counterclockwise for one circle through the transmission device.

[0033] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The suture needle 4 rotates one circle and passes through the introduction groove 10 once.

[0034] Working principle: when it is necessary to suture a wound, the suture thread on the thread reel 1 can first be bolted to the through hole 17 at one end of the suture needle 4, and then the wound can be aligned and closed so that the wound enters from the introduction slot 10. At this time, the button 15 can be pressed to control the start of the motor 7. The motor 7 can drive the suture needle 4 to rotate one circle through the transmission device. The needle 18 at one end of the suture needle 4 can pass through both sides of the wound when passing through the introduction slot 10, that is, the suture needle 4 can drive the suture thread to pass through both sides of the wound to complete a suture. After the suture needle 4 rotates one circle, the introduction slot 10 is moved along the wound. During the movement process, the button 15 is pressed continuously and quickly, so that the suture needle 4 rotates continuously to suture the wound in sequence. After the suture is completed, the suture thread at the tail end of the suture needle 4 can be cut off and the suture thread can be fixed manually. In general, through the cooperation of the suture needle, the first gear, the rotating rod, the second gear, the third gear, the motor and other components, the suture line can be used to suture the wound quickly and continuously, making the skin suture on both sides of the wound easier and smoother. There is no need to use expensive suture staples for suturing, which can reduce the cost of wound suturing. The operation is simple, and even non-medical professionals can easily suture the wound area, achieving the effect of being able to be used in sudden emergency situations. It is very suitable for emergency wound care and is highly practical.
