Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular, relates to an electric laparoscope linear cutting stapler. Background Art

[0002] The electric laparoscopic linear cutting stapler is a medical device used in minimally invasive surgery, mainly used for tissue cutting and suturing in laparoscopic surgery. This device combines the functions of cutting and suturing, and can complete these two tasks in one operation, greatly improving surgical efficiency and reducing surgical time. It is widely used in many fields such as gastrointestinal surgery, thoracic surgery, and general surgery.

[0003] Traditional manual laparoscopic linear cutting staplers require doctors to have a high level of technical skills when performing cutting and stapling operations. The process is relatively complicated and prone to human errors. The surgical operation of the cutting stapler is regulated by an additional complex safety switch structure, that is, the angle of the jaws can only be adjusted before the jaws are closed, and the angle of the jaws cannot be adjusted after the jaws are closed, making the operation cumbersome.

[0004] For example, in the prior art, there is a patent with patent publication number CN103315788B, which discloses a cutting stapler suitable for minimally invasive surgery. The cutting stapler for minimally invasive surgery adjusts the angle of the jaws by alternating movement of two joint connecting plates.

The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] An electric laparoscopic linear cutting stapler, such as Figure 1-Figure 6 As shown, it includes a cutting stapler body 1 with a built-in control system, a support sleeve 2 rotatably arranged on the cutting stapler body 1 and a support tube 3 connected to the support sleeve 2, so that the support sleeve 2 drives the support tube 3 to rotate axially, and the left end of the support tube 3 is provided with a staple cartridge jaw 5 for installing a staple cartridge through a movable hinge part 4, and the staple cartridge jaw 5 is driven by the movable hinge part 4 to rotate along the radial direction of the support tube 3 to adapt to tissue cutting and stapling operations at different angles, and the upper side of the staple cartridge jaw 5 is rotated with a staple anvil jaw 6 for assisting the closure of the staples through a hinge block 61, and the hinge block 61 is rotatably arranged inside the staple cartridge jaw 5, and the staple anvil jaw 6 is connected to the upper side of the hinge block 61, and the staple anvil jaw 6 rotates downward to clamp the tissue to the staple cartridge jaw 5, and then drives the cutting and stapling member 51 sliding on the staple cartridge jaw 5 to slide to cut the tissue and trigger the nails in the staple cartridge to staple the cut tissue; The movable hinge part 4 includes a connecting sleeve 1 41 connected to the first end (left end) of the support tube 3. The upper and lower sides of the connecting sleeve 1 41 are both provided with a center disk 43 rotatably provided through a support plate 42. The support plate 42 is connected to the connecting sleeve. The center disk 43 is rotatably provided on the support plate 42. The center positions of the two center disks 43 overlap in the upper and lower directions. A connecting sleeve 2 44 connected to the nail magazine jaw 5 is connected between the two center disks 43. A joint rubber ring 45 for protection is connected between the connecting sleeve 2 44 and the connecting sleeve 1 41. The center disk 43 is rotated to make the connecting sleeve 2 44 drives the nail magazine jaw 5 to rotate forward and backward to adjust the angle. The second end of the support tube 3 rotates with two upper and lower opposite turntables 71. The eccentric parts of the upper and lower turntables 71 rotate one-to-one with the eccentric parts of the upper and lower center disks 43. A connecting rod 46 that runs through the support tube 3 is movable. The rotating turntable 71 is rotated to make the connecting rod 46 push and pull the center disk 43 to rotate, and the two connecting rods 46 do not interfere with each other. Therefore, the transmission strength can be guaranteed, and the rotation angle of the nail magazine jaw 5 can be maximized. The rotating drive group arranged in the support sleeve 2 drives the turntable 71 to rotate; The electric laparoscopic linear cutting stapler also includes a second connecting rod 62 connected to the hinge block 61, and the second connecting rod 62 is located on the side of the hinge block 61 away from the anvil jaw 6. A hinge plate 63 located inside the connecting sleeve 44 rotates on the second connecting rod 62. The hinge plate 63 is moved rightward to cause the second connecting rod 62 to pull the hinge block 61 to rotate, and the hinge block 61 will drive the anvil jaw 6 to rotate downward to clamp the tissue onto the nail magazine jaw 5. The hinge plate 63 is moved leftward to push the hinge block 61 to rotate in the opposite direction through the second connecting rod 62 to open the anvil. A push-pull plate 64 is slidably provided between the jaw 6, the support tube 3 and the connecting sleeve 1 41, and a transmission plate 65 is rotated between the push-pull plate 64 and the hinge plate 63. The center of rotation between the transmission plate 65 and the push-pull plate 64 overlaps the center of the center disk 43 in the vertical direction. Therefore, when the nail anvil jaw 6 is in an open state, the rotation of the center disk 43 will drive the nail magazine jaw 5 to rotate through the connecting sleeve 2 44, and the nail magazine jaw 5 will drive the transmission plate 65 on the push-pull plate 64 in turn through the hinge block 61, the connecting rod 2 62 and the hinge plate 63. The center plate 43 is rotated synchronously with the center plate 43 as the center, so that on the basis of maximizing the rotation angle of the nail magazine jaw 5, the transmission of the push-pull plate 64 is still maintained to realize the opening and closing of the nail anvil jaw 6, and then the push-pull plate 64 can be moved right to make the transmission plate 65 pull the hinge plate 63 to close the nail anvil jaw 6. At this time, the rotation center between the transmission plate 65 and the push-pull plate 64 does not overlap the center of the center plate 43 in the vertical direction. Therefore, when the nail anvil jaw 6 is closed for cutting and matching, the center plate 43 cannot drive the nail magazine jaw 5 to rotate through the connecting sleeve 2 44, thereby cleverly relying on the misalignment of the transmission structure to achieve the self-locking function, eliminating the complex safety switch structure in the prior art, until the push-pull plate 64 is reset by moving left and releasing the transmission plate 65, and the nail anvil jaw 6 is opened. At this time, the rotation center between the transmission plate 65 and the push-pull plate 64 overlaps the center of the center plate 43 in the vertical direction, and then when the nail anvil jaw 6 is opened, the nail magazine jaw 5 can be rotated normally, and the opening and closing drive group arranged in the support sleeve 2 drives the push-pull plate 64 to move left and right.

[0030] like Figure 8 As shown, the rotation drive group includes a motor 74 installed inside the support sleeve 2. The eccentric part of the turntable 71 rotates the support connecting rod 46 through the connected eccentric rod. A rotating drum 72 is connected between the sides of the eccentric rods of the two turntables 71 that are close to each other. A worm gear 73 is connected to the rotating drum 72. A worm 75 that meshes with the right side of the worm gear 73 is connected to the output shaft of the motor 74. The motor 74 is controlled to drive the worm gear 75 to rotate so as to drive the worm gear 75 to drive the rotating drum 72 to rotate. The rotating drum 72 will drive the turntable 71 to rotate through the eccentric rod, thereby realizing the function of the center disk 43 driving the nail magazine jaw 5 to rotate and adjust the angle through the connecting sleeve 2 44.

[0031] like Figure 8As shown, the opening and closing drive group includes a motor 2 81 installed inside the support sleeve 2, and a screw rod 1 82 is connected to the output shaft of the motor 2 81. The right end of the transmission plate 65 is connected to a nut block 83 that slides through the support tube 3. The nut block 83 is threadedly connected to the screw rod 1 82. The motor 2 81 is controlled to drive the screw rod 1 82 to rotate to drive the nut block 83 to move right. The nut block 83 will drive the push-pull plate 64 to move right to close the anvil jaw 6. When the motor 2 81 is controlled to drive the screw rod 1 82 to rotate in the opposite direction, the nut block 83 will drive the push-pull plate 64 to move left to open the anvil jaw 6.

[0032] like Figure 8 As shown, it also includes a swivel 21 connected to the right side of the support sleeve 2. The swivel 21 rotates and penetrates the cutting stapler body 1. A spur gear ring 22 is connected to one side of the swivel 21. A driving motor 23 is installed inside the cutting stapler body 1. A spur gear 24 meshing with the spur gear ring 22 is connected to the output shaft of the driving motor 23. The driving motor 23 is controlled to drive the spur gear 24 to rotate so as to drive the spur gear ring 22 to drive the swivel 21 to rotate. The swivel 21 will drive the support tube 3 to rotate through the support sleeve 2, thereby rotating the support tube 3 axially to adjust the position of the staple magazine jaw 5.

[0033] like Figure 3 , Figure 5 and Figure 7 As shown, it also includes an elastic push plate 52 connected to one side of the cutting and stapling piece 51. The elastic push plate 52 slides through the support tube 3, the connecting sleeve 1 41, the connecting sleeve 2 44 and the stapler jaw 5. When the elastic push plate 52 moves left, it will drive the cutting and stapling piece 51 to move left to cut the tissue and trigger the staples in the stapler to staple the cut tissue. When the connecting sleeve 2 44 drives the stapler jaw 5 to rotate and adjust the angle, the elastic push plate 52 will adaptively deform and maintain the transmission to the cutting and stapling piece 51. The elastic push plate 52 is driven to move by the linear drive group arranged in the cutting and stapling device body 1.

[0034] like Figure 7 As shown, it also includes: two front-to-rear connecting plates 1 53 and two front-to-rear connecting plates 2 54 are respectively connected to the connecting sleeve 1 41 and the connecting sleeve 2 44, the front and rear two connecting plates 1 53 are respectively located on the front and rear sides of the elastic push plate 52, and the front and rear two connecting plates 2 54 are respectively located on the front and rear sides of the elastic push plate 52, and the two connecting plates 1 53 and the two connecting plates 2 54 are respectively located on the front and rear sides of the elastic push plate 52. Fixed pulleys that contact and cooperate with the elastic push plate 52 are rotated on the two connecting plates 1 53 and the two connecting plates 2 54, and the two connecting plates 2 54 are both connected with resistance blocks 55, and the resistance blocks 55 have rounded corners suitable for contacting and cooperating with the elastic push plate 52. When the connecting sleeve 2 44 drives the nail magazine jaw 5 to rotate and adjust the angle, under the guiding action of the fixed pulley and the extrusion action of the resistance block 55, it is ensured that the elastic push plate 52 will adaptively deform and maintain the transmission of the cutting and anastomosis member 51, and the stability is high.

[0035] like Figure 8-Figure 10 As shown, the linear drive group includes a connecting ring 91 connected to the elastic push plate 52, the connecting ring 91 slides through the support tube 3, one side of the connecting ring 91 is connected to a connecting rod 92 that slides through the rotating ring 21, the rotation of the rotating ring 21 will also drive the connecting ring 91 to rotate through the connecting rod 92, so as not to interfere with each other, the left movement of the connecting rod 92 will drive the elastic push plate 52 to move left through the connecting ring 91 to drive the cutting anastomosis piece 51 to move left to work, a supporting rod 93 that is concentric with the rotating ring 21 rotates between the cutting anastomosis device body 1 and the rotating ring 21, a push-pull disk 94 slides on the supporting rod 93, and an annular groove is opened on the push-pull disk 94, and the connecting rod 92 is connected to the rotating ring 21. The right end of the rod 92 is slidably arranged in the annular groove, so the rotation of the swivel ring 21 will drive the connecting rod 92 to rotate along the annular groove on the push-pull disk 94, and the movement of the push-pull disk 94 can drive the connecting rod 92 to move. A servo motor 95 is installed on the cutting stapler body 1, and a screw rod 2 96 is connected to the output shaft of the servo motor 95. The left end of the screw rod 2 96 is rotatably arranged on the upper left part of the support rod 93. The servo motor 95 is controlled to drive the screw rod 2 96 to rotate to drive the push-pull disk 94 to drive the connecting rod 92 to move, thereby realizing the function of the cutting stapler 51 moving left to cut the tissue and triggering the nails in the nail magazine to staple the cut tissue.

[0036] As a preferred embodiment of the present invention, the two switches for controlling the forward and reverse rotation of motor 1 74 are both installed on the cutting stapler body 1; the two switches for controlling the forward and reverse rotation of motor 2 81 are both installed on the cutting stapler body 1; the two switches for controlling the forward and reverse rotation of the drive motor 23 are both installed on the cutting stapler body 1, thereby facilitating the electric control of the handheld cutting stapler body 1, which is convenient to operate with high precision; the switch for controlling the forward and reverse rotation of the servo motor 95 is installed on the cutting stapler body 1, and when the switch controlling the servo motor 95 is pressed, the servo motor 95 starts for a predetermined time to drive the screw rod 2 96 to rotate forward, and when the switch controlling the servo motor 95 is released, the servo motor 95 starts for a predetermined time to drive the screw rod 2 96 to rotate reversely.
