Description

Technical Field

[0001] The present application relates to the field of staplers, and in particular to an adjustable electric intracavitary cutting stapler. Background Art

[0002] In the medical device field, with the continuous advancement of medical technology, various surgical instruments are constantly being updated and upgraded to meet the increasingly complex needs of surgery. Especially in endovascular surgery, precise and efficient operation is crucial to patient treatment and recovery. Traditional endovascular surgical instruments provide surgeons with some support, but there is still room for improvement in addressing some special circumstances and improving surgical quality. In recent years, people have placed higher demands on the functionality and performance of medical devices, prompting researchers to continuously explore and innovate new surgical instruments.

[0003] In the past, manual cutting and suturing tools were commonly used for intracavitary incision and suturing. Doctors relied on their experience and skills to cut and sew tissue using simple mechanical mechanisms. These manual tools often required simultaneous use of both hands, which was inconvenient in certain situations. Furthermore, some electric staplers, while automated, lacked precise control, making them unsuitable for certain situations and requiring further improvement. Summary of the Invention

[0004] In order to improve the problem that existing staplers cannot select more precise or more convenient adjustments according to specific circumstances, the present application provides an adjustable electric intracavitary cutting stapler.

[0005] The present application provides an adjustable electric intracavitary cutting and stapling device adopting the following technical solutions: An adjustable electric intracavitary cutting stapler comprises a handle, a rotating head, a suturing rod and a suturing head, wherein the suturing rod is connected to the handle, an outer tube is sleeved on the suturing rod, the handle is used to drive the outer tube to move along the length direction of the suturing rod, the rotating head is rotatably connected to the handle, the rotating head is fixed to the outer tube, and is used to drive the outer tube to drive the suturing rod to rotate, the suturing head is rotatably connected to the end of the suturing rod away from the handle through a rotating assembly, the suturing rod is provided with a driving assembly, the driving assembly is connected to the rotating assembly, and is used to drive the rotating assembly to rotate, the rotating head is provided with a handle and a rotating motor, the rotating motor is connected to the driving assembly through an electromagnetic clutch, the handle is rotatably connected to the rotating head and is fixed to the driving assembly.

[0006] By adopting the above technical solution, when in use, the doctor holds the handle so that the suturing head reaches the part to be sutured, then rotates the rotating head to make the suturing rod rotate, driving the suturing head to rotate, so that the suturing head is flush with the part to be sutured, and then manually drives the handle to rotate so that the driving component drives the rotating component to rotate, so that the suturing head is aligned with the part to be sutured. The manual adjustment method enables the rotation angle of the suturing head to be precisely controlled.

[0007] For quick steering, the rotary motor is activated directly. When powered, the electromagnetic clutch is fixedly connected to the drive assembly, allowing the rotary motor to drive the drive assembly to rotate, achieving rapid adjustment of the suture head angle. In the initial state, the rotary motor is powered off, and the electromagnetic clutch is disengaged from the drive assembly, thus not affecting the handle's ability to drive the drive assembly to rotate.

[0008] Optionally, the driving assembly includes a driving gear and two driving racks, a driving rod is coaxially fixed on the driving gear, one end of the driving rod is fixed to the handle, and the other end is connected to the rotating motor, the driving gear can rotate on the suturing rod, the driving gear is located between the two driving racks, the driving gear is engaged with the driving rack, and the driving rack can move along the length direction of the suturing rod.

[0009] By adopting the above technical solution, the handle or rotary motor is used to drive the driving rod to rotate, so that the driving gear rotates, thereby driving the two driving racks to move. Since the two driving racks are located on both sides of the driving gear, the movement directions of the two driving racks are opposite. The movement difference between the two driving racks is used to realize the rotation of the rotating assembly.

[0010] Optionally, the rotating assembly includes a rotating block and two rotating rods, the two rotating rods correspond one-to-one to the driving racks, a card is fixed on the rotating rod, a slot is provided on the driving rack, the card is inserted in the slot, the card can move in the slot along the width direction of the driving rack, and the end of the rotating rod away from the rotating head is hinged to the rotating block.

[0011] By adopting the above technical solution, when the two driving racks move in opposite directions at the same time, the inner wall of the card slot abuts against the card, thereby driving the card to move synchronously, so that the two rotating rods move in opposite directions, so that the two sides of the rotating block shaft are subjected to opposite pulling and pushing forces, so that the rotating block finally rotates in one direction.

[0012] During the movement of the rotating rod, since the connection point between the rotating rod and the rotating block is fixed, when the rotating block rotates, the distance between the two points changes, that is, the distance between the two rotating rods changes, so that the card moves in the card slot along the width direction of the card slot, ensuring that the card is always stuck in the card slot, that is, when the driving rack moves, the rotation of the rotating block is realized.

[0013] Optionally, the suturing head is fixed with a rotating block, the rotating block is coaxially fixed with the rotation block, and the suturing rod is provided with a limiting assembly, which abuts against the rotating block to limit the deflection of the rotating block.

[0014] By adopting the above technical solution, when the rotating block rotates, it drives the rotating block to rotate synchronously, thereby realizing the steering of the suturing head. During the rotation of the rotating block, the limit assembly contacts the side wall of the rotating block, playing a limiting role, so that the rotating block always rotates on a plane without ups and downs, so that the suturing head will not deflect and turn, thereby increasing the stability of the suturing head steering.

[0015] Optionally, the limiting assembly includes a limiting ring and several limiting balls. The limiting ring is arranged on the suturing rod and is coaxial with the rotating block. Several mounting holes are opened on the side wall of the rotating block away from the rotating block. Several of the mounting holes are evenly distributed along the circumference of the rotating block. Several of the limiting balls correspond to the mounting holes one by one. The limiting balls are inserted into the mounting holes, and the side walls of the limiting balls are connected to the limiting ring.

[0016] By adopting the above technical solution, when the rotating block rotates, the limiting ball slides on the limiting ring, causing the limiting ball to rotate under the action of friction, thereby converting the sliding friction between the rotating block and the limiting ring into rolling friction, which reduces the friction and facilitates the rotation of the rotating block, making the steering of the suture head smoother. The diameter of the limiting ball is fixed, and matched with the size of the mounting hole, the depth of the limiting ball inserted into the mounting hole is fixed, thereby fixing the distance between the limiting ring and the rotating block, thereby ensuring the fixed position of the rotating block and improving the stability of the rotating block during rotation. The design of the limiting ball can limit the rotating block without interfering with its rotation.

[0017] Optionally, a moving assembly is provided on the suturing rod, and the moving assembly is connected to the limiting ring and is used to drive the limiting ring to approach the rotating block.

[0018] By adopting the above technical solution, the moving assembly is started to drive the limit ring toward the rotating block until the limit ball contacts the side wall of the limit ring, thereby limiting the rotating block.

[0019] Optionally, the moving assembly includes a moving ring, several guide blocks and several moving blocks, the moving ring is provided on the suturing rod and can rotate on the suturing rod, the moving ring is located on the side of the limiting ring away from the rotating block, and the moving ring is coaxial with the limiting ring, the guide block is fixed on the side wall of the moving ring close to the limiting ring, and several of the guide blocks are evenly distributed along the circumference of the moving ring, the moving block is fixed on the side wall of the limiting ring close to the moving ring, and several of the limiting blocks correspond to the guide blocks one by one, and a guide surface is provided on the guide block. When the guide surface abuts against the moving block, it is used to drive the moving block to drive the limiting block to move in the direction close to the rotating block.

[0020] By adopting the above technical solution, the movable ring is rotated so that the lowest point of the guide surface on the guide block begins to contact the movable block, and the movable block slides relatively on the guide surface. Because the guide surface is set obliquely, it guides the movable block, causing the movable block to gradually move away from the movable ring, thereby driving the limit ring to approach the rotating block. Because the guide block and the movable block are evenly distributed, the force on the entire circle of the limit ring is uniform, ensuring the stable translation of the limit ring and making the distance between the limit ring and the rotating block equal at all points, thereby improving the stability of the rotation block limit. When the suture head needs to be detached, the movable ring is reversed, so that the distance between the rotating block and the limit ring is larger, so that the suture head and the part to be sutured can be separated.

[0021] Optionally, a cavity is provided in the limiting ring, and an adjustment ring is provided in the cavity. The adjustment ring can move in the cavity toward or away from the rotating block, and the adjustment ring can be connected to the limiting ring to pull the limiting ball out of the mounting hole.

[0022] By adopting this technical solution, in the initial state, the adjustment ring is close to the rotating block, causing the stop ball to abut against the stop ring. When the rotating block needs to be fixed, the adjustment block is connected to the stop ball, driving the adjustment ring away from the rotating block, and the stop ball is retracted into the cavity. At this point, there is no foreign matter between the stop ring and the rotating block. The moving ring is then rotated, bringing the stop ring closer to the rotating block until the stop ring abuts against the rotating block, thereby installing and fixing the rotating block, preventing it from rotating and achieving a fixed angle for the suture head.

[0023] Optionally, a plurality of electromagnetic blocks are provided on the adjusting ring, and the plurality of electromagnetic blocks correspond one-to-one to the limiting balls. A connecting hole is provided on the side wall of the limiting ring close to the rotating block, corresponding to the electromagnetic block. The electromagnetic block is inserted into the corresponding connecting hole. The electromagnetic block can be attracted to the limiting ball. An electromagnet is provided on the inner wall of the cavity. The electromagnet can be attracted to the adjusting ring to accommodate the electromagnetic ring in the cavity.

[0024] By adopting the above technical solution, the electromagnet is energized, exerting suction on the adjusting ring, thereby driving the adjusting ring to move away from the rotating block. At the same time, the electromagnetic block is started, so that the electromagnetic block adsorbs the corresponding limit ball and drives the limit ball through the connecting hole until it is completely pulled out of the mounting hole, thereby ensuring that the limit ring can be abutted against the rotating block, thereby fixing the rotating block.

[0025] Optionally, a slider is provided on the side wall of the adjustment ring, and a movable groove is provided on the inner wall of the cavity. The slider is inserted into the movable groove and can move in the movable groove. A spring is provided in the movable groove, and the spring is used to push the slider to drive the adjustment ring to move toward the rotating block.

[0026] By adopting the above technical solution, when the electromagnet is powered off, the spring drives the slider to move toward the rotating block, so that the electromagnetic block is inserted into the corresponding connecting hole, thereby making the electromagnetic block flush with the side wall of the limit ring, ensuring that the side wall of the limit ring is a complete plane, so that when the rotating block rotates, the limit ball can stably roll and slide on the side wall of the limit ring.

[0027] In summary, this application has at least one of the following beneficial effects: 1. When in use, the doctor holds the handle and makes the suturing head reach the part to be sutured. Then, he rotates the rotating head to make the suturing rod rotate, driving the suturing head to rotate, so that the suturing head is flush with the part to be sutured. Then, he manually drives the handle to rotate so that the driving assembly drives the rotating assembly to rotate, so that the suturing head is aligned with the part to be sutured. The manual adjustment method enables the rotation angle of the suturing head to be precisely controlled. In order to quickly turn, the rotating motor is directly started. When powered on, the electromagnetic clutch is fixedly connected to the driving assembly, so that the rotating motor can drive the driving assembly to rotate, so as to achieve rapid adjustment of the suturing head angle. 2. Rotate the moving ring so that the lowest point of the guide surface on the guide block begins to contact the moving block, and the moving block slides relatively on the guide surface. Because the guide surface is set at an angle, it guides the moving block, causing the moving block to gradually move away from the moving ring, thereby driving the limit ring close to the rotating block. Because the guide block and the moving block are evenly distributed, the force on the entire circle of the limit ring is even, ensuring stable translation of the limit ring, so that the distance between the limit ring and the rotating block is equal, thereby improving the stability of the rotation block limit. When the suture head needs to be detached, the moving ring is reversed to increase the distance between the rotating block and the limit ring to facilitate the separation of the suture head from the part to be sutured.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-6 This application is described in further detail.

[0031] The present application discloses an adjustable electric intracavitary cutting and stapling device. Figure 1 and Figure 2 The adjustable electric intracavitary cutting and stapling device includes a handle 10, a rotating head 20, a suturing rod 30 and a suturing head 40, wherein one end of the suturing rod 30 is connected to the handle 10, and an outer tube 31 is provided on the suturing rod 30. The handle 10 can drive the outer tube 31 to move along the length direction of the suturing rod 30, the rotating head 20 is rotatably connected to the handle 10, the rotating head 20 is fixed to the outer tube 31, and can drive the outer tube 31 to drive the suturing rod 30 to rotate, and the suturing head 40 is rotatably connected to the end of the suturing rod 30 away from the handle 10 through a rotating assembly 50. The suturing rod 30 is provided with a driving assembly 60, which is connected to the rotating assembly 50 and can drive the rotating assembly 50 to rotate. The rotating head 20 is provided with a handle 130 and a rotating motor 140. The rotating motor 140 is connected to the driving assembly 60 through an electromagnetic clutch 141. The handle 130 is rotatably connected to the rotating head 20 and is fixed to the driving assembly 60. Such a structure enables the cutting and stapling device to be adjusted in multiple dimensions to adapt to different surgical scenarios.

[0032] Reference Figure 2 and Figure 3Specifically, the drive assembly 60 includes a drive gear 61 and two drive racks 62, and a drive rod is coaxially fixed to the drive gear 61. The drive rod is usually made of metal and has good strength and rigidity to ensure stable power transmission. The drive rod can also be made of high-strength plastic to reduce the overall weight. One end of the drive rod is fixed to the handle 130, and the other end is connected to the rotary motor 140, so that both the handle 130 and the rotary motor 140 can drive the drive gear 61 to rotate.

[0033] Reference Figure 2 and Figure 3 The drive gear 61 is capable of rotating on the suturing rod 30. The drive gear 61 is located between the two drive racks 62 and meshes with the drive racks 62. The drive racks 62 are capable of moving along the length of the suturing rod 30. When the drive gear 61 rotates, it drives the meshed drive racks 62 to move linearly. Because the two drive racks 62 are located on either side of the drive gear 61, the two drive racks 62 move in opposite directions.

[0034] Reference Figure 3 and Figure 4 Specifically, the rotating assembly 50 includes a rotating block 51 and two rotating rods 52, and the two rotating rods 52 correspond one to one with the driving rack 62. The rotating rod 52 is provided on the suturing rod 30, and the rotating rod 52 is arranged along the length direction of the suturing rod 30. A card 521 is integrally formed on the end of the rotating rod 52 close to the handle 10, and a card slot 621 is provided on the driving rack 62. The card 521 is inserted into the card slot 621, and the card 521 can move in the card slot 621 along the width direction of the driving rack 62. The end of the rotating rod 52 away from the rotating head 20 is hinged to the rotating block 51. This hinged connection allows the rotating rod 52 to rotate around the hinge point. When the driving rack 62 moves, it will drive the rotating rod 52 to move through the card 521, thereby causing the rotating block 51 to rotate.

[0035] During the movement of the rotating rod 52, since the connection point between the rotating rod 52 and the rotating block 51 is fixed, when the rotating block 51 rotates, the distance between the two points changes, that is, the distance between the two rotating rods 52 changes, so that the card 521 moves in the card slot 621 along the width direction of the card slot 621, ensuring that the card 521 is always stuck in the card slot 621, that is, when the driving rack 62 moves, the rotation of the rotating block 51 is realized.

[0036] Reference Figure 3 and Figure 4Specifically, the suturing head 40 is fixed with a rotating block 70, which is coaxially fixed with the rotating block 51. The coaxial fixing of the rotating block 70 and the rotating block 51 can be achieved by a key connection to ensure synchronous rotation of the two. The suturing rod 30 is provided with a limit assembly 80, which abuts the rotating block 70 to limit the deflection of the rotating block 70. The provision of the limit assembly 80 ensures the accuracy and stability of the rotation angle of the suturing head 40.

[0037] Reference Figure 4 and Figure 5 Specifically, the limiting assembly 80 includes a limiting ring 81 and a plurality of limiting balls 82. The limiting ring 81 is provided on the suturing rod 30 and is coaxial with the rotating block 70. The limiting ring 81 is annular in structure. A plurality of mounting holes 71 are formed on the side wall of the rotating block 70 away from the rotating block 51. The plurality of mounting holes 71 are evenly distributed along the circumference of the rotating block 70. The plurality of limiting balls 82 correspond to the mounting holes 71 one by one. The limiting balls 82 are inserted into the mounting holes 71, and the side walls of the limiting balls 82 abut against the limiting ring 81.

[0038] When the rotating block 70 rotates, the limiting ball 82 slides on the limiting ring 81, causing the limiting ball 82 to rotate under the action of friction, thereby converting the sliding friction between the rotating block 70 and the limiting ring 81 into rolling friction, which reduces the friction and facilitates the rotation of the rotating block 70, making the steering of the suture head 40 smoother. The diameter of the limiting ball 82 is fixed, and it matches the size of the mounting hole 71, so that the depth of the limiting ball 82 inserted into the mounting hole is fixed, thereby maintaining a fixed distance between the limiting ring 81 and the rotating block 70, thereby ensuring the fixed position of the rotating block 70 and improving the stability of the rotating block 70 during rotation. The design of the limiting ball 82 allows it to limit the rotating block 70 without interfering with its rotation.

[0039] Reference Figure 4 and Figure 5 Specifically, a moving assembly 90 is provided on the suturing rod 30, and the moving assembly 90 is connected to the limiting ring 81, and is used to drive the limiting ring 81 close to the rotating block 70. The function of the moving assembly 90 is to adjust the position of the limiting ring 81 and further accurately control the rotation of the suturing head 40.

[0040] Reference Figure 4 and Figure 5Specifically, the moving assembly 90 includes a moving ring 91, a plurality of guide blocks 92 and a plurality of moving blocks 93. The moving ring 91 is provided on the suturing rod 30 and can rotate on the suturing rod 30. The moving ring 91 is driven to rotate by a motor, and the motor is installed on the suturing rod 30. The moving ring 91 is usually made of rubber to increase the friction with the suturing rod 30. It can also be made of a plastic material with anti-slip patterns on the surface. The moving ring 91 is located on the side of the limiting ring 81 away from the rotating block 70, and the moving ring 91 is coaxial with the limiting ring 81. The guide block 92 is fixed on the side wall of the moving ring 91 close to the limiting ring 81, and the plurality of guide blocks 92 are evenly distributed along the circumference of the moving ring 91. The guide block 92 is a wedge-shaped structure, and its guide surface 921 plays a guiding role. The moving block 93 is fixed on the side wall of the limiting ring 81 close to the moving ring 91, and the plurality of moving blocks 93 correspond one-to-one to the guide block 92. When the moving ring 91 rotates, the guide surface 921 of the guide block 92 abuts against the moving block 93 , which drives the moving block 93 to drive the limiting ring 81 to move toward the rotating block 70 .

[0041] The movable ring 91 is rotated so that the lowest point of the guide surface 921 on the guide block 92 begins to contact the movable block 93, causing the movable block 93 to slide relatively on the guide surface 921. Because the guide surface 921 is set at an angle, it guides the movable block 93, causing the movable block 93 to gradually move away from the movable ring 91, thereby driving the limit ring 81 closer to the rotating block 70. Because the guide block 92 and the movable block 93 are evenly distributed, the force on the limit ring 81 is uniform throughout the entire circle, ensuring stable translation of the limit ring 81 and making the distance between the limit ring 81 and the rotating block 70 equal at all points, thereby improving the stability of the limit of the rotating block 70. When it is necessary to detach the suture head 40, the movable ring 91 is reversed, so that the distance between the rotating block 70 and the limit ring 81 is larger, so that the suture head 40 can be separated from the part to be sutured.

[0042] Reference Figure 5 and Figure 6 Specifically, a cavity 811 is defined within the retaining ring 81, within which an adjustment ring 110 is located. A slider 112 is provided on the sidewall of the adjustment ring 110. A movable groove 814 is defined on the inner wall of the cavity 811 along the length of the suturing rod 30. The slider 112 is inserted into and movable within the movable groove 814. A spring 120 is provided within the movable groove 814. One end of the spring 120 is secured to the interior of the movable groove 814, while the other end is secured to the slider 112. The elastic force of the spring 120 pushes the adjustment ring 110 toward the rotating block 70.

[0043] Reference Figure 5 and Figure 6, a number of electromagnetic blocks 111 are provided on the adjustment ring 110, and the electromagnetic blocks 111 correspond one-to-one to the limiting balls 82. The electromagnetic block 111 is a cylindrical structure, consisting of an iron core and a coil. A connecting hole 813 is provided on the side wall of the limiting ring 81 close to the rotating block 70, corresponding to the electromagnetic block 111. The electromagnetic block 111 is inserted into the corresponding connecting hole 813, and the electromagnetic block 111 can be attracted to the limiting ball 82. An electromagnet 812 is provided on the inner wall of the cavity 811, and the electromagnet 812 can be attracted to the adjustment ring 110, and is used to accommodate the adjustment ring 110 in the cavity 811. When the electromagnet 812 is energized, it will attract the adjustment ring 110, so that the electromagnetic block 111 is separated from the limiting ball 82.

[0044] In the initial state, the adjustment ring 110 is close to the rotating block 70 under the action of the spring 120, and the electromagnetic block 111 is inserted into the corresponding connecting hole 813, so that the electromagnetic block 111 is flush with the side wall of the limiting ring 81, ensuring that the side wall of the limiting ring 81 is a complete plane, so that when the rotating block 70 rotates, the limiting ball 82 can stably roll and slide on the side wall of the limiting ring 81.

[0045] Electromagnet 812 is energized, exerting suction on adjustment ring 110, thereby driving adjustment ring 110 away from rotating block 70. Simultaneously, electromagnetic block 111 is activated, causing it to attract the corresponding stop ball 82 and drive the stop ball 82 through connection hole 813 until it is completely withdrawn from mounting hole 71. At this point, there is no foreign matter between stop ring 81 and rotating block 70. The movable ring 91 is then rotated, bringing stop ring 81 closer to rotating block 70 until it abuts against it, thereby securing the rotating block 70 and preventing it from rotating, thereby fixing the angle of suture head 40.

[0046] The adjustable electric intracavitary stapler of the present invention is implemented as follows: through the coordinated operation of multiple components, including a handle 10, a rotating head 20, a drive assembly 60, a rotation assembly 50, a stop assembly 80, and a moving assembly 90, the angle and position of the suturing head 40 can be flexibly adjusted. Furthermore, the rotation of the suturing head 40 can be achieved through both manual adjustment of the handle 130 and automatic adjustment of the rotary motor 140, enabling precise or rapid adjustment as needed.

[0047] The handle 10 drives the outer tube 31 to move the suturing rod 30, while the rotating head 20 causes the suturing rod 30 to rotate. The driving assembly 60 and the rotating assembly 50 control the rotation of the suturing head 40, and the limiting assembly 80 and the moving assembly 90 precisely control the rotation angle and position of the suturing head 40. This structural design overcomes the limitation of conventional intracavitary cutting and stapling instruments, which lacks the flexibility to adjust the angle and position. It improves the precision and adaptability of surgical operations, better meets the diverse needs of different surgical scenarios, and provides more effective protection for patient treatment.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
