However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example

[0027] Reference Figure 1-5 This is an embodiment of the present invention, which provides a laparoscopic stapler for minimally invasive surgery, comprising:

[0028] The device mechanism 100 includes a handle 102 fixedly installed on the surface of the main body 101, a rod 103 fixedly installed on the surface of the main body 101, and a mating head 104 disposed at the end of the rod 103.

[0029] The adjustment mechanism 200 includes an adjustment component 201 for adjusting the width of the adjustment handle 102, and a limiting component 202 for improving the adjustment stability of the adjustment component 201.

[0030] The width of the handle 102 can be adjusted by adjusting the cooperation between the adjustment component 201 and the limiting component 202, which can meet the needs of different users and effectively solve the problem that the width of the traditional endoscopic stapler handle is fixed and not suitable for different users, thereby improving the user's comfort and ease of operation.

[0031] Specifically, the adjustment assembly 201 includes a mounting groove 201a formed on the surface of the handle 102, an adjustment plate 201b slidably mounted in the inner cavity of the mounting groove 201a, a base plate 201c fixedly mounted on the bottom of the handle 102, a plurality of slots 201d formed on the top of the base plate 201c, a limiting groove 201e formed on the surface of the base plate 201c, an adjustment spring 201f fixedly mounted on the surface of the adjustment plate 201b, and a retaining ball 201g fixedly mounted on the end face of the adjustment spring 201f and used in conjunction with the slots 201d.

[0032] Furthermore, the adjustment assembly 201 also includes a frame 201h fixedly installed at the bottom of the adjustment plate 201b, a connecting plate 201i fixedly installed inside the frame 201h, and a push rod 201j slidably installed on the connecting plate 201i and used in conjunction with the ball 201g.

[0033] The frame 201h and the connecting plate 201i work together to keep the push rod 201j synchronized with the adjusting plate 201b, so that the push rod 201j is always below the ball 201g, which makes it easier to squeeze the ball 201g.

[0034] Preferably, two first springs are fixedly installed in the inner cavity of the mounting groove 201a, and the end faces of the first springs are fixedly connected to the surface of the adjusting plate 201b.

[0035] The first spring is used to push the adjustment plate 201b out of the mounting slot 201a, so as to avoid the inconvenience of the user to remove the adjustment plate 201b from the mounting slot 201a.

[0036] Furthermore, the surface of the base plate 201c has two sliding grooves for use with the frame 201h, and the surface of the adjusting plate 201b has a groove for installing the adjusting spring 201f.

[0037] Among them, the sliding groove is used to limit the movement of the frame 201h, thereby improving the movement stability of the frame 201h and preventing it from deviating.

[0038] Specifically, a second spring is fixedly installed at the bottom of the connecting plate 201i, and a pressing plate is fixedly installed on the end face of the second spring.

[0039] The pressing plate is fixedly connected to the end of the push rod 201j, and the surface of the connecting plate 201i is provided with a hole and slot for use with the push rod 201j. The second spring is used to spring the push rod 201j downward to reset it.

[0040] Furthermore, the limiting component 202 includes a guide strip 202a fixedly installed in the inner cavity of the mounting groove 201a, a guide groove 202b having an adjustment plate 201b surface and used in conjunction with the guide strip 202a, and a stop block 202c fixedly installed on the surface of the guide strip 202a.

[0041] The guide bar 202a and the guide groove 202b are used to limit the adjustment plate 201b and improve the stability of the adjustment plate 201b when it moves. The stop block 202c is used to limit the adjustment plate 201b and prevent the adjustment plate 201b from leaving the interior of the mounting groove 201a.

[0042] When using the device, if the width of the handle 102 needs to be adjusted, the user needs to press the pressing plate upwards. The pressing plate drives the push rod 201j to move upwards, so that the push rod 201j squeezes the retaining ball 201g and retracts the retaining ball 201g into the groove. The pressing plate is blocked by the frame 201h, and the push rod 201j cannot extend into the groove. The adjusting spring 201f is in a compressed state. At this time, the first spring pushes the adjusting plate 201b out of the mounting slot 201a. The user needs to keep pressing the pressing plate and move it with the adjustment plate 201b.

[0043] Adjust the adjustment plate 201b to a suitable position to change the width of the handle 102. After adjustment, release the pressing plate. Under the elastic force of the adjustment spring 201f, the retaining ball 201g will spring open, so that the retaining ball 201g will engage with the corresponding retaining groove 201d, thus completing the adjustment of the width of the handle 102.

[0044] In summary, by adjusting the cooperation between the adjustment component 201 and the limiting component 202, the usable width of the handle 102 can be adjusted to meet the needs of different users. This effectively solves the problem that the width of the traditional laparoscopic stapler handle is fixed and not suitable for different users, thereby improving the user's comfort and ease of operation.
