[0035] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0036] like Figures 1 to 8 As shown, a laparoscopic stapler with adjustable olecranon angle comprises an anvil 1, an olecranon 2 and a limiting mechanism;

[0037] The front end of the anvil 1 is provided with a mounting hole 3 extending in the left-right direction, and the inner wall of the mounting hole 3 is evenly distributed with limiting tooth grooves 4 extending in the left-right direction;

[0038] The hawk's beak 2 is connected to a connecting post 5 for detachably inserting into the mounting hole 3. The outer wall of the connecting post 5 is provided with at least one limiting protrusion 6 adapted to the limiting tooth groove 4. The limiting protrusion 6 is used to snap into the corresponding limiting tooth groove 4 when the connecting post 5 is inserted into the mounting hole 3 to limit the angle of the connecting post 5 in the mounting hole 3; thereby, the angle of the hawk's beak 2 relative to the anvil 1 can be limited.

[0039] The limiting mechanism is connected to the anvil 1 and is used to limit the connecting column 5 within the mounting hole 3 after the connecting column 5 is inserted into the mounting hole 3.

[0040] Specifically, when it is necessary to adjust the angle of the beak 2, the limiting mechanism is first used to release the restriction on the connecting column 5, and the connecting column 5 is removed from the mounting hole 3. At this time, the beak 2 is removed from the anvil 1. The beak 2 is then adjusted to the required angle, the angle of the beak 2 is maintained, and the connecting column 5 is reinserted into the mounting hole 3 at the new angle. Then, the limiting protrusion 6 is re-engaged with the limiting tooth groove 4. After the connecting column 5 is inserted into place, the limiting mechanism is used to limit the connecting column 5 in the mounting hole 3 again. At this time, the angle of the beak 2 relative to the anvil 1 is adjusted, and the angle of the beak 2 can be adjusted according to usage requirements.

[0041] This embodiment also includes a stapler body 7 and a staple magazine 8, wherein the staple magazine 8 is rotatably connected to the stapler seat 1, and the stapler seat 1 is connected to the front end of the stapler body 7; specifically, the outer wall of the connecting column 5 is evenly covered with a plurality of the limiting protrusions 6.

[0042] like Figure 4 、 6 As shown in Figures 7 and 8, the front end portion of the dowel seat 1 is provided with a gap groove 9 connected to the mounting hole 3, and the connecting column 5 is provided with a transition portion 10 connected to the eagle beak 2, and the transition portion 10 is used to fit in the gap groove 9 when the connecting column 5 is inserted into the mounting hole 3.

[0043] like Figures 2 to 8 As shown, the mounting hole 3 passes through the anvil 1 in the left-right direction;

[0044] The limiting mechanism may include a blocking plate 11 and a blocking mechanism;

[0045] The blocking plate 11 is connected to one side of the anvil 1 and blocks the first end of the mounting hole 3;

[0046] The blocking mechanism is connected to the other side end of the anvil 1 and is used to block and open the second end of the mounting hole 3. Specifically, when the blocking mechanism opens the second end of the mounting hole 3, the connecting column 5 can be inserted into or removed from the mounting hole 3 from the second end, and when the blocking mechanism blocks the second end of the mounting hole 3, the connecting column 5 can be confined within the mounting hole 3.

[0047] like Figure 6 As shown, the blocking plate 11 can be connected to an elastic pad 12 for extending into the first end of the mounting hole 3 and abutting against one end of the connecting column 5; specifically, arranging the elastic pad 12 against the connecting column 5 can eliminate the left and right movement of the eagle's beak 2.

[0048] like Figure 7 As shown, the anvil seat 1 may be provided with a groove 13 for installing the blocking plate 11, and the blocking plate 11 is locked and installed in the groove 13; specifically, the blocking plate 11 is locked and installed in the groove 13 by screws.

[0049] like Figures 2 to 6 As shown, the blocking mechanism may include a blocking slider 14 and a spring 15;

[0050] The blocking slider 14 is connected to the anvil 1 in a sliding manner along the front-back direction. During the sliding process, the blocking slider 14 has a blocking position for blocking the second end of the mounting hole 3 and an open position for opening the second end of the mounting hole 3.

[0051] One end of the spring 15 abuts against the anvil 1 , and the other end of the spring 15 abuts against the blocking slider 14 . The spring 15 is used to drive the blocking slider 14 to move to the blocking position through elastic force.

[0052] like Figures 2 to 6 As shown, the blocking mechanism may further include a limiting plate 16;

[0053] The anvil 1 is provided with a slide groove 17 for mounting the blocking slider 14;

[0054] The blocking slide is provided with a sliding portion 18 that slides into the slide groove 17 and a protrusion 19 connected to the sliding portion 18 , and a step portion 20 is provided between the sliding portion 18 and the protrusion 19 ;

[0055] The limiting plate 16 is connected to the anvil 1 and is used to abut against the step portion 20 to limit the sliding portion 18 on the blocking slide to the sliding groove 17;

[0056] The limiting plate 16 is provided with an opening slot 21 that cooperates with the protrusion 19 .

[0057] Specifically, when the angle of the beak 2 needs to be adjusted, the blocking slider 14 is first slid backward to the open position to open the second end of the mounting hole 3, and then the connecting column 5 is removed from the mounting hole 3. At this time, the beak 2 is removed from the anvil 1. The beak 2 is then adjusted to the required angle, the angle of the beak 2 is maintained, and the connecting column 5 is reinserted into the mounting hole 3 at the new angle, so that the limiting protrusion 6 is re-engaged with the limiting tooth groove 4. After the connecting column 5 is inserted into place, the blocking slider 14 is released. The spring 15 drives the blocking slider 14 forward to the blocking position through elastic force to block the second end of the mounting hole 3. At the same time, the first end of the mounting hole 3 is blocked by the blocking plate 11, thereby confining the connecting column 5 within the mounting hole 3. At this time, the angle of the beak 2 relative to the anvil 1 is adjusted, so that the angle of the beak 2 can be adjusted according to usage requirements. In this embodiment, the spring 15 is also installed in the slide groove 17.

[0058] like Figures 2 to 6 As shown, the raised portion 19 may be provided with an anti-slip stripe portion 22, and the anvil 1 is provided with a recessed portion 23 for mounting the limiting plate 16; specifically, the limiting plate 16 is mounted in the recessed portion 23 by screw locking.

[0059] like Figure 3 、 6 As shown in FIG. 8 , an upper groove wall 24 is provided above the chute 17 , and an inclined limiting portion 25 inclined downward from the rear to the front is provided at the front end of the upper groove wall 24 ;

[0060] The front end portion of the blocking slider 14 is provided with an inclined surface 26 which abuts against the inclined limiting portion 25 when the blocking slider 14 slides forward to the blocking position.

[0061] In summary, when it is necessary to adjust the angle of the beak 2, first, the limiting mechanism is used to release the restriction on the connecting column 5, and the connecting column 5 is removed from the mounting hole 3. At this time, the beak 2 is removed from the anvil 1. Then, the beak 2 is adjusted to the required angle, the angle of the beak 2 is maintained, and the connecting column 5 is reinserted into the mounting hole 3 at the new angle, and then the limiting protrusion 6 is re-engaged with the limiting tooth groove 4. After the connecting column 5 is inserted into place, the connecting column 5 is again restricted in the mounting hole 3 by the limiting mechanism. At this time, the angle of the beak 2 relative to the anvil 1 is adjusted, and the angle of the beak 2 can be adjusted according to usage requirements.
