DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] The present application embodiment discloses an electric laparoscopic stapler, such as Figure 1 As shown, it includes a handle 1, in which a control component is arranged. The control component is used to control the electric driving action of the stapler to drive the staplers to cut and suture the tissue of the patient.

[0034] like Figure 1 As shown, the stapler also includes a connecting member 2, a staple magazine member 3 and a swinging assembly 4. One end of the connecting member 2 is connected to the handle 1. The connecting member 2 and the staple magazine member 3 are connected through the swinging assembly 4. When the swinging assembly 4 is driven to swing, the swinging assembly 4 drives the staple magazine member 3 to swing, which is convenient for medical staff to adjust according to the surgical site.

[0035] like Figure 1 and 2 As shown, an operating component 5 is also provided in the handle 1, and the operating component 5 includes an operating knob 51 and an operating block 52. The operating knob 51 is rotatably connected to the handle 1, and an operating gear 54 is fixedly connected to the operating knob 51. The operating block 52 is slidably connected in the handle 1, and an operating rack 53 is fixedly connected to the operating block 52, and the operating rack 53 is meshed with the operating gear 54.

[0036] like Figure 2 , 3 As shown in FIG. 4 , the swing assembly 4 includes a swing link 41 and a swing plate 42. The swing plate 42 is fixedly connected to the nail magazine member 3. The swing plate 42 has two opposite sides with hanging holes. The swing link 41 has two hanging holes, which correspond to the swing link 41 one by one. The hanging holes are used to hang the swing link 41. The operation block 52 has a connecting groove, and the swing link 41 is fixedly connected with a connecting plate 411. The connecting plate 411 is clamped in the connecting groove to achieve the connection between the swing link 41 and the operation block 52.

[0037] The operator rotates the operating knob 51 , which drives the operating gear 54 to rotate, and the operating gear 54 drives the operating rack 53 to move, and the operating rack 53 drives the swing link 41 to move accordingly, and the swing link 41 moves, thereby driving the swing plate 42 to rotate.

[0038] like Figure 2 and 3 As shown, the swing assembly 4 also includes a locking plate 43, a locking rod 44 and a locking spring 45. The locking plate 43 is coaxial with the swing plate 42 and fixedly connected. A locking plug 431 is fixedly connected to the locking plate 43. A plurality of locking plugs 431 are arranged along the circumference of the locking plate 43. In this embodiment, the angle between each two adjacent locking plugs 431 is 15°. The locking rod 44 is slidably connected to the connector 2. A locking slot 441 is provided at the end of the locking rod 44. The locking slot 441 is inserted into the locking plug 431. That is, the locking plate 43 rotates once with the swing plate 42, rotates 15°, rotates twice, rotates 30°, and so on. The locking spring 45 is sleeved on the locking rod 44, and the end of the locking spring 45 away from the locking rod 44 is fixedly connected to the inner wall of the connector 2.

[0039] like Figure 3 and 4 As shown, the end of the locking rod 44 is fixedly connected with a pushing tooth block 442, and the peripheral surface of the swing plate 42 is provided with a pushing tooth groove 421, and a plurality of pushing tooth grooves 421 are provided, and the opening angle of the pushing tooth groove 421 is 90°, so that the swing plate 42 and the locking rod 44 will not be self-locked. When the operator operates the swing plate 42 to rotate, the groove wall of the pushing tooth groove 421 can push the pushing tooth block 442 away. The locking plug block 431 is separated from the locking slot 441, and the swing plate 42 can drive the nail magazine part 3 to rotate freely. When it is rotated to the right position, the locking plug block 431 enters the locking slot 441 again to lock and limit the position of the swing plate 42.

[0040] like Figure 4 and 5 As shown, the stapler further includes a positioning assembly 6, which includes a positioning slider 61 and a positioning link 62. The positioning slider 61 is slidably connected to the locking plug block 431, and one end of the positioning slider 61 abuts against the bottom of the locking slot 441. The locking plate 43 is also slidably connected with a matching plug rod 63, which is fixedly connected to one end of the positioning link 62. The positioning slider 61 is provided with a matching slot 1 611 and a matching slot 2 612 for the matching plug rod 63 to be inserted, and the slot depth of the matching slot 1 611 is less than the slot depth of the matching slot 2 612. The matching slot 1 611 is provided on a side close to the locking rod 44, and the matching slot 2 612 is provided on a side away from the locking rod 44. A wedge surface is provided on the slot wall of the matching slot 2 612 on a side close to the locking rod 44.

[0041] Before the swing plate 42 rotates, one end of the positioning slider 61 extends out of the locking plate 43, and the matching rod 63 is located in the matching slot 2 612. The swing plate 42 is driven to rotate, which drives the locking block 431 to rotate and extend into the locking slot 441, thereby driving the positioning slider 61 to move, driving the matching rod 63 to move, so that the matching rod 63 moves from the matching slot 2 612 along the wedge surface into the matching slot 1 611. Since the groove depth of the matching slot 1 611 is less than the groove depth of the matching slot 2 612, the matching rod 63 extends relative to the locking plate 43, which drives the positioning link 62 to move.

[0042] like Figure 5 As shown, the positioning assembly 6 also includes a positioning display 64, which is fixedly connected to the inside of the handle 1, and the display screen of the positioning display 64 is arranged outside the handle 1. A positioning patch 621 is fixedly connected to one end of the positioning link 62 away from the mating plug 63, and a connecting patch 641 is fixedly connected to the positioning display 64. After the positioning link 62 is displaced, the positioning patch 621 is driven to move, and after the connecting patch 641 is attached to the positioning patch 621, the positioning display 64 is powered on and lights up to display the rotation angle.

[0043] like Figure 5 As shown, the end of the positioning slider 61 away from the locking rod 44 is fixedly connected to a sliding spring 613, and the end of the sliding spring 613 away from the positioning slider 61 is fixedly connected to the inner wall of the locking plate 43. The matching rod 63 is sleeved with a matching spring 631, and the side of the matching spring 631 away from the matching rod 63 is connected to the inner wall of the locking plate 43. After the locking rod 44 drives the positioning slider 61 to move, the sliding spring 613 is in a compressed state, and the matching rod 63 moves into the matching slot 1 611, and the matching spring 631 is also in a compressed state. When the nail magazine part 3 needs to be reset, the swing link 41 is moved in the reverse direction to drive the swing plate 42 to rotate. Under the action of the sliding spring 613 and the matching spring 631, the positioning slider 61 is reset, and the matching rod 63 is reset and moved to the matching slot 2 612. It is convenient to use and can be used repeatedly.

[0044] The implementation principle of an electric laparoscopic stapler in the embodiment of the present application is: When the operator needs to operate the staple cartridge 3 to swing the angle, the operating knob 51 is turned to drive the operating gear 54 to rotate, and the operating gear 54 synchronously drives the operating racks 53 on both sides to move, and the two operating racks 53 move relative to each other. The operating rack 53 drives the swing link 41 to move, drives the swing plate 42 and the push tooth block 442 to rotate, and pushes the tooth block 442 to move out of the push tooth groove 421, and the locking rod 44 gives way, and the swing plate 42 synchronously drives the locking plate 43 to rotate, and the locking plug 431 on the locking plate 43 cooperates with the locking slot 441 at the end of the locking rod 44, and locks and clamps, so as to limit the swing angle of the staple cartridge 3.

[0045] In order to facilitate the operator to make a timely and clear judgment on whether the position of the nail magazine component 3 is stable after swinging, when the locking plug 431 extends into the locking slot 441, the bottom of the locking slot 441 abuts against the positioning slider 61 in the corresponding locking plug 431, and the positioning slider 61 presses the sliding spring 613. The matching plug 63 is driven to move from the matching slot 2 612 to the matching slot 1 611, and the matching plug 63 drives the positioning link 62 to extend out of the locking plate 43, so that the positioning patch 621 and the connecting patch 641 are in contact, that is, the positioning display 64 lights up, indicating that the locking plug 431 is inserted into the locking slot 441 at this time, and the positions of the swing plate 42 and the nail magazine component 3 are stable, and the subsequent surgical operation can be continued. The structure is simple, the use is convenient, and the surgical quality is further improved.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
