Description

Technical Field

[0001] This invention belongs to the field of skin suture device technology, and specifically relates to a skin suture device with a spiral spring. Background Technology

[0002] A skin suture device is a medical instrument used to close lacerations, wounds, and other openings on the skin surface. It allows for quick, accurate, and painless suturing. It can replace traditional surgical suturing methods, such as needle and thread suturing or glue closure, and offers advantages such as shorter suturing time, simpler operation, and faster recovery. Therefore, it has been widely used in the medical field.

[0003] Existing skin suture devices typically contain no more than 35 staples. In some very large surgical wound suturing, a single suture device may not have enough staples, requiring the use of 2-3 suture devices to complete the suturing operation. Moreover, the staple ejection speed is relatively slow. Existing devices use spring clips and movable handles, with the end of the spring clip bending and engaging with the handle's locking slot to work together to eject staples. However, the staple ejection speed is slow, which can easily cause staple jamming, affecting the progress of the surgical suturing. The staple ejection force is also relatively unstable. Furthermore, the design of the locking components and handle assembly's snap-fit ​​connection can lead to loose connections in practical applications, affecting the surgical operation process. Summary of the Invention

[0004] The purpose of this invention is to provide a skin suture device with a spiral spring, aiming to solve the problem that existing suture devices often have insufficient staple count for suturing large surgical wounds, requiring the use of 2-3 suture devices to complete the suturing operation. Furthermore, the staple ejection speed is relatively slow. Existing devices use a spring and a movable handle, with the spring's tail end bending and engaging with the handle's slot to work together to eject staples. However, this results in a slow ejection speed, a tendency for staples to get stuck, affecting the progress of the suturing operation, and relatively unstable staple ejection force. Additionally, the design of the snap-fit ​​connection between the snap-fit ​​components and the handle assembly can lead to loose connections in practical applications, affecting the surgical procedure.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0035] Embodiment 1

[0036] Please refer to Figures 1-7 The present application provides the following technical solutions:

[0037] A skin stapler with a volute spring, comprising:

[0038] The fixed handle 3;

[0039] The limiting groove 7 is formed in the end of the two inner walls of the fixed handle 3;

[0040] The movable handle 2 is located in the fixed handle 3;

[0041] The stepped slide 301 is fixedly connected to one side of the inner wall of the fixed handle 3;

[0042] The staple ejecting mechanism comprises a staple cartridge assembly 101, a volute spring 102, a staple 103, a clamping spring piece 104, a spring piece 105, a mounting slot 107, a groove 108, a straight spring piece 401, a thick spring 402 and a spring piece assembly 403. The staple cartridge assembly 101 is located at the lower end of the fixed handle 3. The mounting slot 107 is arranged at the upper end of the staple cartridge assembly 101. The clamping spring piece 104 is slidingly connected in the mounting slot 107. The volute spring 102 is located in the mounting slot 107. The staple 103 is located at the upper end of the clamping spring piece 104. The groove 108 is arranged at the upper end of the staple cartridge assembly 101. The straight spring piece 401 is located at the close end of the inner wall of the groove 108 and the fixed handle 3. The spring piece 105 is located in the staple cartridge assembly 101. The spring piece assembly 403 is located in the fixed handle 3. The thick spring 402 is arranged at one side end of the spring piece assembly 403. The straight spring piece 401 is located between the spring piece assembly 403 and the stepped slide 301.

[0043] In a specific embodiment of the present invention, both ends of the spring assembly 403 and the movable handle 2 are provided with fixing rods. Through the fixing rods, the spring assembly 403 and the movable handle 2 can move and be supported within the two limiting grooves 7. Positioned by the fixing rods, when a person presses one side of the movable handle 2, the other side will move downward in an arc shape. When the device is shipped from the factory, the retaining spring 104 is inserted into the mounting groove 107. Then, the front half of the mounting groove 107 has a slot of a suitable size for the spiral spring 102. The spiral spring 102 is placed into the mounting groove 107, and multiple sewing staples 103 are arranged in sequence. After placing the staple cartridge assembly 101 on the upper end of the spring member 104 and aligning it with 1, the staple cartridge assembly 101 and the fixing handle 3 are bonded together using plastic laser welding. The bottom of the straight spring piece 401 is located in the groove 108, and the top is attached to the spring piece assembly 403. The top of the straight spring piece 401 holds the first suture staple 103 in place. The fixing rod on one side of the spring piece assembly 403 allows it to move within one of the limiting grooves 7. When the operator presses the movable handle 2, the other end of the movable handle 2 contacts the spring piece assembly 403 downwards, and in conjunction with the compression of the thick spring 402, the staple is dislodged through the spring member 105. The screws utilize a spiral spring 102 instead of a variable pitch telescopic spring, allowing for the loading of more suture screws 103 without altering the overall volume. This is suitable for suturing wounds in large surgeries. Compared to the mechanical linkage screw ejection mechanism of commonly used suture devices, the front end of the fixing handle 3 is designed as a stepped slide 301, working in conjunction with a straight spring 401. The straight spring 401 presses out the suture screws 103, resulting in faster and more stable screw ejection.
