Abstract
Description
Technical Field
[0001] This utility model relates to the field of laparoscopic anastomotic devices, and more particularly to an electric laparoscopic anastomotic device. Background Technology
[0002] Anastomosing devices are surgical instruments used as an alternative to manual sutures. They work by using titanium or stainless steel staples to separate or anastomose tissue, similar to a stapler. Compared to traditional manual sutures, instrumental suturing offers several advantages: faster suturing, simpler operation, and reduced surgical time; single-use, avoiding cross-infection; tight and appropriate sutures using titanium or stainless steel staples; fewer side effects and surgical complications; and the ability to remove previously inoperable tumors, making it highly favored by surgeons.
[0003] The application of staplers has expanded to various fields such as gastrointestinal surgery, hepatobiliary surgery, thoracic surgery, urology, and obstetrics and gynecology, becoming an indispensable tool for doctors. Using instruments instead of manual suturing offers patients numerous advantages, including less intraoperative bleeding, shorter operation time, reduced errors caused by manual techniques, avoidance of infection, and faster postoperative functional recovery.
[0004] During surgery, medical staff rotate the center wheel of the oscillating head to move the oscillating head lever along the axis of the laparoscopic stapler, thereby causing the working head of the laparoscopic stapler to swing. However, manually rotating the center wheel increases the workload and complexity of the operation, as medical staff must manually adjust the rotation of the oscillating head. Furthermore, traditional manually rotated laparoscopic staplers only have three settings and a maximum rotation angle of 45°, which limits their practical clinical use and prevents them from increasing the rotation angle of the laparoscopic stapler. In addition, traditional laparoscopic staplers do not allow for adjustment of both the rotation direction and the flipping direction of the laparoscopic stapler; only one adjustment method can be adjusted, which is quite limiting. Utility Model Content
[0005] (1) Technical problems to be solved
[0006] To overcome the problem that manual rotation adjustment of the steering head by medical staff increases their workload, and that the maximum rotation angle of 45° is limited in actual clinical use, it is necessary to address the issue that the rotation angle of the laparoscopic anastomosis device cannot be increased, and that it is impossible to adjust both the rotation direction and the flipping direction of the laparoscopic anastomosis device. The limitation of only being able to adjust one method is significant.
[0007] (2) Technical solution
[0008] The technical solution of this utility model is as follows: an electric laparoscopic anastomosis device, including an laparoscopic anastomosis device body, a connecting rod, a support rod, a rotating head, an laparoscopic anastomosis device head body, a bending adjustment component, a locking rotation component, and a position adjustment component.

[0009] Preferably, by setting a bending adjustment component, the working head of the laparoscopic anastomosis device can be bent and rotated, thereby improving the effectiveness of the laparoscopic anastomosis device during use and maximizing the bending degree of the working head. Then, by using a locking rotation component, the working head of the laparoscopic anastomosis device can be rotated, making it convenient for medical personnel to rotate the working head, thus improving the ease of operation of the device.

Locking blocks are symmetrically installed on the surface of the drive rod and engage with the shaped block. A second gear is installed on the surface of the moving rod and meshes with a first gear. This allows for the rotation of the endoscopic stapler head, reducing limitations in the use of the device and expanding its functionality.
[0013] Furthermore, a second hydraulic rod is installed inside the connecting rod. The telescopic end of the second hydraulic rod passes through the connecting rod and extends into the interior of the support rod, connecting with the moving rod. This facilitates use by medical personnel and provides convenience for the operation of the device.

A torsion spring is fitted onto the hinge rod on the surface of the movable seat. One end of the torsion spring is installed on the surface of the movable seat, and the other end is connected to the irregular block. This assists the device in resetting, greatly facilitating the operation of medical personnel.
[0015] Furthermore, the position adjustment assembly includes a push plate, an adjustment plate, a guide rod, and a return spring. The push plate is mounted on the surface of the moving rod. An adjustment plate is rotatably connected between the rectangular block and the hydraulic rod. The adjustment plate is slidably connected in a through groove on the surface of the support rod. A guide rod is slidably connected in a through hole on the surface of the adjustment plate. Both ends of the guide rod pass through the adjustment plate and are installed in the through groove on the surface of the support rod. A return spring is sleeved on the surface of the guide rod.

[0033] Example 2:
[0034] Please see Figure 1-7In this embodiment, the engaging rotation assembly 7 includes a movable rod 701, a rectangular block 702, a connecting disc 703, a conical block 704, a shaped block 705, a movable seat 706, a locking block 707, a drive rod 708, and a gear 709.

A connecting disc 703 is mounted at one end of the rectangular block 702. Conical blocks 704 are symmetrically mounted on the surface of the movable rod 701. A movable seat 706 is symmetrically mounted on the surface of the connecting disc 703. The shaped block 705 is hinged to the surface of the movable seat 706. The rotating head 4... A drive rod 708 is mounted on the side surface. One end of the drive rod 708 passes through the rotating head 4 and extends into the interior of the support rod 3. A locking block 707 is symmetrically mounted on the surface of the drive rod 708, engaging with the irregularly shaped block 705. A gear 709 is mounted on the surface of the moving rod 701, meshing with a gear 608. A hydraulic rod 710 is installed inside the connecting rod 2. The telescopic end of the hydraulic rod 710 passes through the connecting rod 2 and extends into the interior of the support rod 3, connecting with the moving rod 701. A torsion spring 711 is sleeved on the surface of the drive rod 708, with one end of the torsion spring 711 installed inside the support rod 3. The other end of torsion spring 711 is mounted on the surface of drive rod 708. Torsion spring 712 is sleeved on the hinge rod of movable seat 706. One end of torsion spring 712 is mounted on the surface of movable seat 706, and the other end of torsion spring 712 is connected to irregular block 705. Position adjustment assembly 8 includes push plate 801, adjustment plate 802, guide rod 803, and return spring 804. Push plate 801 is mounted on the surface of moving rod 701. Adjustment plate 802 is rotatably connected between rectangular block 607 and hydraulic rod 606. Adjustment plate 802 is slidably connected in the through groove opened on the surface of support rod 3. The through hole opened on the surface of adjustment plate 802 slides in the through groove. A guide rod 803 is dynamically connected, with both ends of the guide rod 803 passing through the adjusting plate 802 and installed in the through groove opened on the surface of the support rod 3. A return spring 804 is sleeved on the surface of the guide rod 803. One end of the return spring 804 is connected to the adjusting plate 802, and the other end of the return spring 804 is installed in the through groove opened on the surface of the support rod 3. This allows the working head of the laparoscopic stapler body 1 to be rotated, avoiding manual rotation by medical staff, further improving the rotation efficiency of the working head of the laparoscopic stapler body 1, and enabling the switching and adjustment of the rotation direction and flipping direction of the working head of the laparoscopic stapler body 1.
[0035] Workflow: When adjusting the angle of the laparoscopic stapler head body 5 on the laparoscopic stapler body 1, the servo motor 610 is first started. At this time, the output end of the servo motor 610 drives the connecting rod 609 to rotate. During the rotation of the connecting rod 609, the rectangular block 607 rotates. During the rotation of the rectangular block 607, the hydraulic rod 606 rotates, which in turn drives the worm gear 605 to rotate. Since the worm gear 605 meshes with the worm wheel 604, when the worm gear 605 rotates, it drives the worm wheel 604 to rotate. During the rotation of the worm wheel 604, it drives the synchronous belt 603 to rotate. At this time, the synchronous belt 603 drives the rotating rod 602 to rotate, so that the rotating rod 602 drives the laparoscopic stapler head body 5 to adjust the angle through the hinge seat 601.
[0036] When the head body 5 of the laparoscopic stapler is rotated, hydraulic rod 710 is activated first. The telescopic end of hydraulic rod 710 drives moving rod 701 to move inside support rod 3. When moving rod 701 moves, it slides on the surface of rectangular block 702. At this time, the conical block 704 on moving rod 701 pushes the irregular block 705 on connecting disc 703 to rotate inside movable seat 706. During the rotation of irregular block 705, torsion spring 712 is deformed. Torsion spring 712 can assist irregular block 705 in resetting, thereby further improving the operation of the device. After the position adjustment is completed, irregular block 705 is engaged with the surface of locking block 707, so that moving rod 701... When connected to the drive rod 708, the moving rod 701 drives the second gear 709 to mesh with the first gear 608. At this time, the servo motor 610 drives the first gear 608 on the connecting rod 609 to rotate. During the rotation of the first gear 608, the second gear 709 is driven to rotate, which in turn drives the moving rod 701 to rotate. During the overall rotation, the drive rod 708 is driven to rotate. During the rotation of the drive rod 708, the first torsion spring 711 is deformed. The first torsion spring 711 can assist the drive rod 708 in resetting. During the rotation of the drive rod 708, the head body 5 of the laparoscopic stapler is driven to rotate, thereby adjusting the rotation of the head body 5 of the laparoscopic stapler.
[0037] When the rotation and flipping directions of the head body 5 of the endoscope stapler are switched, the hydraulic rod 606 is activated, causing the worm gear 605 to retract or extend, thereby disengaging or engaging with the worm wheel 604. Then, the hydraulic rod 710 is activated, causing the moving rod 701 to move the gear 709, allowing the gear 709 to engage or disengage with the gear 608. During the movement of the moving rod 701, the moving rod 701 drives the push plate 801 to push the adjusting plate 802. The adjusting plate 802 slides on the surface of the guide rod 803 during this movement, allowing the guide rod 803 to adjust. The adjustment plate 802 moves to guide the guide rod 803 and prevents it from shifting position during movement. When the adjustment plate 802 slides on the surface of the guide rod 803, it presses the return spring 804. The return spring 804 assists the adjustment plate 802 in resetting, thereby further improving the effectiveness of the device. At this time, the adjustment plate 802 drives the rectangular block 702 to disengage from the rectangular groove on the surface of the connecting rod 609, thereby preventing the connecting rod 609 from driving the hydraulic rod 606 to rotate during rotation, which would affect the rotation adjustment of the endoscopic anastomosis head body 5. This allows for switching between the rotation direction and the flipping direction of the endoscopic anastomosis head body 5.
[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
