The body is usually provided with a rotating pull rod, a rotating pull tab, and an angle adjustment assembly for pushing and pulling the rotating pull rod. The cutting assembly is provided with a turning structure that matches the rotating pull rod. The angle adjustment assembly on the body is further divided into an electric stepless angle adjustment assembly and a mechanical angle adjustment assembly. For the mechanical angle adjustment assembly, when rotating the cutting assembly, it is necessary to operate the angle adjustment knob on the body so that the angle adjustment assembly can push and pull the rotating pull rod on the body by rotating the pull tab, thereby causing the rotating pull rod to push and pull the turning structure on the cutting assembly to operate the steering of the cutting assembly.

That is, the stapler gun body belongs to the mechanical angle adjustment assembly.

[0004] However, the above patent still has the following shortcomings: it is inconvenient to operate, and it is easy to rotate or dial back when turning, resulting in safety hazards during the operation. Utility Model Content

It should be added that even if the dial is dialed back under special circumstances, the frustration feedback to the hand can make the operator distinguish that the handle is accidentally touched, so as to take timely countermeasures.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0056] like Figure 1 to Figure 7 As shown, in the embodiment of the utility model, a stapler angle adjustment seat 103 is provided, comprising a housing cover 1 formed with a mounting cavity 11, and also comprising: a gear wheel 2, a first limiting protrusion 31 and a rotary handle 4 arranged in the mounting cavity 11. Among them:

[0057] The gear wheel 2 is provided with a first hole 21 in the axial direction, and a first limiting groove 22 and a limiting tooth 23 are provided on the side wall;

[0058] A first limiting protrusion 31 elastically abuts against an inner wall of the first limiting groove 22;

[0059] The rotary handle 4 is inserted into the first hole 21 and is limited with the gear wheel 2, and an eccentric cam 42 extending from the mounting cavity 11 is provided at the bottom. Specifically, the eccentric cam 42 is used to push and pull the rotating pull rod 101 in the stapler. Preferably, the rotating pull rod 101 is movably connected with a rotating pull tab 102, and the rotating pull tab 102 is provided with a bayonet 1021 that is engaged by the eccentric cam 42. The first limiting groove 22, the limiting tooth 23 and the first limiting cam 31 are all provided with arc surfaces to improve the sliding effect and make the connection smoother.

[0060] In this solution, a first limiting groove 22 and a limiting tooth 23 are provided on the gear wheel 2, and a first limiting protrusion 31 is provided on the elastic stop plate 3 to be inserted into and abut against the first limiting groove 22, thereby ensuring that the gear wheel 2 and the rotary handle 4 can be limited in time and effectively without affecting the rotation of the rotary handle 4, thereby effectively avoiding the gear wheel 2 and the rotary handle 4 from rotating or dialing back, and reducing safety hazards during the operation.

[0061] In addition, for the electric stepless angle adjustment component, since the stepless knob 104 is easy to turn, it is easy to cause the problem of accidental rotation or excessive rotation, which will also cause safety hazards in the surgical process. In this scheme, a plurality of first limit grooves 22 and limit teeth 23 with intervals can be set on the gear wheel 2 to achieve multi-level or multi-gear angle adjustment. The more and more precise the number of first limit grooves 22 and limit teeth 23, the more precise the rotation angle control. And when the gear wheel 2 rotates, when the first limit protrusion 31 is dialed from the current first limit groove 22 to the next first limit groove 22, a certain sense of frustration will be fed back to the hand, so that the operator can clearly feel the feedback of the first limit protrusion 31 alternating between being dialed and limited by the sense of frustration, and the operation sense is strong, and it is easier to distinguish the amplitude of the angle rotation. It should be added that even if the dial is dialed back under special circumstances, the frustration feedback to the hand can make the operator distinguish that the handle 4 is accidentally touched, so as to take timely countermeasures.

[0063] The mounting plate 5 is arranged at the bottom of the mounting cavity 11, and a circular groove 51 matching the gear wheel 2 is provided in the middle. The gear wheel 2 is placed in the circular groove 51, and the circular groove 51 is provided with a second hole 52 that is directly opposite to the first hole 21. Specifically, the gear wheel 2 is limited in a timely and effective manner to prevent the gear wheel 2 from running out of position when rotating, thereby causing a safety hazard.

[0064] In another embodiment, Figure 3 and Figure 4 As shown, the rotary handle 4 is respectively penetrated through the first hole 21 and the second hole 52, and a rotary disk 41 is synchronously rotated at the bottom of the rotary handle 4, and the eccentric locking protrusion 42 is eccentrically arranged on a side of the rotary disk 41 away from the rotary handle 4. Specifically, the rotary disk 41 is provided with a locking notch 411, and a retractable protrusion inserted into the locking notch 411 is arranged from the stapler body 100, so as to realize the locking of the rotary handle 4 and avoid mis-turning caused by mis-touch, that is, the rotary handle 4 can be rotated only when the retractable protrusion is pulled out of the locking notch 411, thereby further reducing installation hazards.

[0065] In yet another embodiment, Figure 2and Figure 4 As shown, the inner wall of the first hole 21 is provided with a second limiting protrusion 211, and the outer wall of the rotary handle 4 is provided with a second limiting groove 43 which is inserted into the second limiting protrusion 211. Specifically, when the rotary handle 4 is inserted into the first hole 21 of the gear wheel 2, the rotary handle 4 and the gear wheel 2 can rotate synchronously.

[0066] In yet another embodiment, Figure 2 and Figure 4 As shown, the stapler angle adjustment seat 103 also includes:

[0067] The elastic stopper 3 is vertically placed in the installation cavity 11 and is adjacent to the gear wheel 2. The first limiting protrusion 31 is provided on the side of the elastic stopper 3 facing the gear wheel 2. Specifically, two elastic stopper sheets 3 are provided, which are respectively distributed on both sides of the gear wheel 2. The inner wall of the installation cavity 11 is provided with a plurality of insertion slots 112, and the two ends of the elastic stopper sheet 3 are respectively inserted into the corresponding insertion slots 112 of the inner wall of the installation cavity 11. The stopping effect is good, so that the sense of frustration generated when the gear wheel 2 rotates is more significant, and it is not easy to move, and the stability is high. It does not occupy too much space in the installation cavity 11, and the structural compactness of the installation cavity 11 is further improved.

[0068] In another embodiment, if Figure 2 to Figure 4 As shown, the stapler angle adjustment seat 103 also includes:

[0069] An installation cover 6 is sealed on the top of the installation cavity 11, a socket 61 for the rotary handle 4 to be inserted is arranged in the middle of the top of the installation cover 6, a waist-shaped groove 62 is arranged on the top edge of the installation cover 6, and an insertion strip 63 is arranged on the bottom edge of the installation cover 6; and

[0070] An elastic member 7 is disposed in the mounting cavity 11 and between the gear wheel 2 and the mounting cover 6;

[0071] Among them, the inner wall of the installation cavity 11 is provided with a third limiting groove 111, the outer edge of the installation disk 5 is provided with a third limiting protrusion 53 inserted into the third limiting groove 111, and the insertion strip 63 is inserted into the third limiting groove 111 and abuts against the third limiting protrusion 53. Specifically, the structure is compact, the occupied space is saved, and the assembly capacity density of the installation cavity 11 is improved. The elastic member 7 is preferably a wave spring, which further improves the compactness of the structure and reduces the occupied space, and the wave spring is not easy to be misplaced, so that the anastomosis angle adjustment seat 103 is more stable, further reduces the safety hazards during the operation, and also improves the service life of the instrument. The top of the gear wheel 2 is also coaxially provided with a connecting wheel, and the connecting wheel and the gear wheel 2 form a double gear structure. The top of the installation cover 6 is provided with a countersunk groove inserted by the connecting wheel, which further strengthens the rotation stability of the gear wheel 2. In detail, the installation cavity 11 is open at the top and bottom, and is sealed by the installation cover 6 and the bottom by the installation disk 5.

[0072] A stapler body 100, such as Figure 5 to Figure 7 As shown, it includes: a rotating pull rod 101, a rotating pull tab 102 and a stapler angle adjustment seat 103. Among them:

[0073] Rotate the pull rod 101;

[0074] A rotating pull tab 102, one end of which is connected to the rotating pull rod 101, and the other end of which is provided with a bayonet 1021; and

[0075] The stapler angle adjustment seat 103 has an eccentric locking protrusion 42 inserted into the bayonet 1021;

[0076] The stapler angle adjustment seat 103 is any one of the above-mentioned stapler angle adjustment seats 103. Figure 5 , turn knob 104 in the positive direction, see Figure 1 to Figure 4 The knob 104 drives the handle 4 and the gear wheel 2 to rotate synchronously, and the eccentric convex 42 at the bottom of the handle 4 rotates synchronously and drives Figure 6-7The rotating pull tab 102 moves, the rotating pull tab 102 pushes the rotating rod 101 to move forward, the rotating rod 101 pushes the turning structure on the cutting assembly 200, and the turning structure drives the cutting assembly 200 to swing to the right and turn. When the cutting assembly 200 needs to turn left, the knob 104 is rotated in the opposite direction, so that the eccentric clamping protrusion 42 drives the rotating pull tab 102 to move, so as to pull the rod to move backward, and the rotating rod 101 tightens the turning structure on the cutting assembly 200, and the turning structure drives the cutting assembly 200 to swing to the left and turn. Since the elastic stop sheet 3 is provided with a first limiting protrusion 31 that is inserted into and abuts against the first limiting groove 22, it is ensured that the gear wheel 2 and the rotating handle 4 can be limited in time and effectively without affecting the rotation of the rotating handle 4, effectively avoiding the gear wheel 2 and the rotating handle 4 from rotating or dialing back, and reducing the safety hazards during the operation. When the gear wheel 2 rotates and the first limiting protrusion 31 is dialed from the current first limiting groove 22 to the next first limiting groove 22, a certain sense of frustration will be fed back to the hand, so that the operator can clearly feel the feedback of the first limiting protrusion 31 alternating between being dialed and limited by the sense of frustration, with a strong sense of operation, and it is easier to distinguish the amplitude of the angle rotation. It should be added that even if the dial is dialed back under special circumstances, the sense of frustration fed back to the hand can enable the operator to distinguish that the handle 4 is accidentally touched, so as to take timely countermeasures.

[0077] In another embodiment, if Figure 5 to Figure 7 As shown, the stapler body 100 also includes:

[0078] The knob 104 is connected to the handle 4 for synchronous rotation. Specifically, the handle 4 and the knob 104 are both provided with matching latch holes, and synchronous rotation is achieved through the latch connection. The knob 104 can be easily applied with force, making it easier for the handle 4 to rotate.

[0079] In another embodiment, if Figure 1 and Figure 5 As shown, the stapler body 100 also includes:

[0080] The knob 104 is synchronously connected with the handle 4 and is provided with a fourth limiting projection inserted into the waist groove 62. Specifically, the fourth limiting projection moves in the waist groove 62, and the waist groove 62 limits the rotation angle of the knob 104 by limiting the fourth limiting projection, thereby avoiding excessive rotation and causing damage to the device.

[0081] A stapler, such as Figure 5 to Figure 7 As shown, it comprises: a body 100 and a cutting assembly 200. Wherein:

[0082] The body 100 has a rotating pull rod 101;

[0083] The cutting assembly 200 is detachably connected to the body 100 and includes a turning structure detachably connected to the rotating rod 101;

[0084] The body 100 is the aforementioned stapler body 100. Figure 5 , turn knob 104 in the positive direction, see Figure 1 to Figure 4 The knob 104 drives the handle 4 and the gear wheel 2 to rotate synchronously, and the eccentric convex 42 at the bottom of the handle 4 rotates synchronously and drives Figure 6-7 The rotating pull tab 102 moves, the rotating pull tab 102 pushes the rotating rod 101 to move forward, the rotating rod 101 pushes the turning structure on the cutting assembly 200, and the turning structure drives the cutting assembly 200 to swing to the right. When the cutting assembly 200 needs to turn left, the knob 104 is rotated in the opposite direction, so that the eccentric clamping protrusion 42 drives the rotating pull tab 102 to move, so as to pull the rod to move backward, and the rotating rod 101 tightens the turning structure on the cutting assembly 200, and the turning structure drives the cutting assembly 200 to swing to the left.

[0085] In this solution, by setting the first limiting groove 22 and limiting teeth 23 on the gear wheel 2, and setting the first limiting protrusion 31 on the elastic stop plate 3 to be inserted into and abutted against the first limiting groove 22, it is ensured that the gear wheel 2 and the handle 4 can be limited in time and effectively without affecting the rotation of the handle 4, effectively avoiding the gear wheel 2 and the handle 4 from rotating or dialing back, and reducing the safety hazards during the operation. In addition, for the electric stepless angle adjustment component or the electric turning stapler, since the stepless knob 104 is easy to dial, it is easy to cause the problem of accidental rotation or excessive rotation, which will also cause safety hazards during the operation. In this solution, a plurality of first limiting grooves 22 and limiting teeth 23 distributed at intervals can be set on the gear wheel 2 to achieve multi-level or multi-gear angle adjustment. The more the number of first limiting grooves 22 and limiting teeth 23, the finer the rotation angle control. When the gear wheel 2 rotates and the first limiting protrusion 31 is dialed from the current first limiting groove 22 to the next first limiting groove 22, a certain sense of frustration will be fed back to the hand, so that the operator can clearly feel the feedback of the first limiting protrusion 31 alternating between being dialed and limited by the sense of frustration, with a strong sense of operation, and it is easier to distinguish the amplitude of the angle rotation. It should be added that even if the dial is dialed back under special circumstances, the sense of frustration fed back to the hand can enable the operator to distinguish that the handle 4 has been accidentally touched, so as to take timely countermeasures.

[0086] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
