They cut and suture tissues by moving forward steadily and at a uniform speed; the rotary motion connection mechanism of its micro-motor is converted into forward and backward motion, and the cutting and pushing of titanium nails into shape will not be fast or slow at times, and the forming force applied to the titanium nails is consistent. The titanium nail forming state is also more stable and the consistency is better, which can greatly reduce the problem of poor titanium nail forming and can effectively reduce the occurrence of medical accidents such as anastomotic bleeding and anastomotic leakage.

[0003] In the electric stapler of the prior art, such as Chinese patent application CN113892989A, a hose is inserted into the through hole of the strip seat, and then the control box is matched with the gun rod assembly, and then the first shell covers the control box, and then the second shell is installed. The first shell and the second shell are clamped together by the first buckle and the second buckle. At this time, the first shell presses the control box, the position of the control box is fixed, the notch is matched with the strip seat, and the rubber sealing layer is in contact with the strip seat and the gun rod assembly, so that the visual system makes it easy to sew and anastomose in a narrow surgical field and a deeper part. By connecting the wireless transmission module with the display device, the internal situation can be observed in real time, reducing the probability of suturing errors; the visual system can be sealed and protected by the isolation cover, and after the suturing is completed, the visual system can be disassembled and reused, which greatly saves costs.

[0016] Compared with the prior art, the present invention provides an electric linear cutting stapler having the following features:

[0017] Beneficial effects:

[0018] 1. When the electric linear cutting stapler is anastomosing the stapler box and the stapler holder, the rotation of the stapler holder drives the supporting frame to rotate synchronously, so that the supporting frame rotates out from the bottom of the stapler holder to both sides, so as to support the human tissues on both sides of the anastomosis. After the cutting and anastomosis process, based on the subjective judgment of the medical staff, if the human tissues on one side of the anastomosis are cut off after the cutting and anastomosis, the medical staff controls the stapler to extend the limiting soft shaft above one side of the cut human tissues, and at the same time, extends the fixing plate above one side of the cut human tissues, so that the cut human tissues are fixed on the supporting frame, so that the cut human tissues can be taken out together with the stapler, effectively avoiding the situation that the forceps pierce the anastomosis, and increasing the safety when using the stapler.

[0019] 2. The electric linear cutting stapler pushes the limit flexible shaft to move through the first electric telescopic rod. The limit flexible shaft passes through the guide limit of the guide member, so that the limit flexible shaft extends to the top of the human tissue at the anastomosis site. At the same time, the limit flexible shaft drives the iron layer to move. After the limit flexible shaft moves, the iron layer moves to be adjacent to the magnet layer, so that the magnet layer generates a greater suction force on the iron layer, thereby pushing the iron layer against the human tissue, so that the limit flexible shaft limits the human tissue, effectively limiting the cut human tissue on the supporting frame, preventing the cut human tissue from falling off when it is large, and improving the use quality of the clamping mechanism.

[0020] 3. The electric linear cutting stapler sets the clamping mechanism at the bottom of the nail seat so that it does not affect the normal use of the nail box and the nail seat. At the same time, some structures are synchronously driven when the nail seat rotates, which effectively reduces the use cost of the stapler and ensures the normal use of the stapler, thereby indirectly improving the use quality of the stapler.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes an electric linear cutting stapler.

[0033] In a typical implementation of the present application, Figure 1-9 As shown, an electric linear cutting stapler comprises a slender body 1, a stapler mechanism 2 arranged on the slender body 1, and a clamping mechanism 3 arranged on the stapler mechanism 2, wherein the stapler mechanism 2 comprises a staple box 25 and a staple seat 27, wherein the staple box 25 is fixedly mounted at one end of the slender body 1, and a staple seat 27 is arranged on the staple box 25;

[0034] The clamping mechanism 3 includes a supporting frame 37, a limiting flexible shaft 310, and a fixing plate 314. A plurality of supporting frames 37 are arranged at the bottom of the nail seat 27. The supporting frames 37 are symmetrically distributed. The supporting frames 37 are all provided with a limiting flexible shaft 310, and the supporting frames 37 are all provided with a fixing plate 314.

[0035] When the nail box 25 and the nail base 27 are combined for anastomosis, the rotation of the nail base 27 drives the support bases 37 on both sides to rotate, and the support bases 37 support the human tissues on both sides of the anastomosis. The medical staff controls the stapler to drive the limiting soft shaft 310 and the fixing plate 314, so that the limiting soft shaft 310 cooperates with the support base 37 to limit the cut human tissue on one side, and the fixing plate 314 cooperates with the support base 37 to fix the cut human tissue on one side.

[0036] When using the present invention:

[0037] The medical staff first takes the stapler and extends the slender body 1 to the anastomosis, aligns the stapler box 25 with the stapler seat 27 and places them at the anastomosis, so that the stapler box 25 is located above the anastomosis and the stapler seat 27 is located below the anastomosis, and then the medical staff controls the stapler to rotate the stapler seat 27 relative to the stapler box 25 to close the stapler seat 27 and the stapler box 25 to squeeze and fix the anastomosis. At the same time, the rotation of the stapler seat 27 drives the supporting frame 37 to rotate synchronously, so that the supporting frame 37 rotates out from the bottom of the stapler seat 27 to both sides to form support for the human tissues on both sides of the anastomosis, and the medical staff starts the stapler to make the stapler box 25 cooperate with the stapler seat 27 to cut and staple the anastomosis, and then after the medical staff's subjective judgment, if the human tissue on one side of the anastomosis is cut off after cutting and anastomosis, the medical staff controls the stapler to put the cut human tissue on one side. The limiting flexible shaft 310 is extended, so that the limiting flexible shaft 310 is moved to the upper side of the cut human tissue, and is clamped with the supporting base frame 37 to limit the cut human tissue. At the same time, the medical staff controls the stapler to extend the fixing plate 314 above the side of the cut human tissue, so that the fixing plate 314 fixes the cut human tissue against the supporting base frame 37. After the stapler is stapled, the nail box 25 is separated from the nail seat 27, and the supporting base frame 37 is synchronously retracted to the bottom of the nail seat 27. Because the limiting flexible shaft 310 limits the cut human tissue, and the fixing plate 314 fixes the cut human tissue, the cut human tissue is retracted to the bottom of the nail seat 27 along with the supporting base frame 37, and when the medical staff retracts the stapler, the cut human tissue is taken out together.

[0038] When the stapler 25 and the stapler base 27 are anastomosed, the rotation of the stapler base 27 drives the support base 37 to rotate synchronously, so that the support base 37 rotates out from the bottom of the stapler base 27 to both sides, thereby supporting the human tissues on both sides of the anastomosis. After the cutting and anastomosis process, based on the subjective judgment of the medical staff, if the human tissues on one side of the anastomosis are cut off after the cutting and anastomosis, the medical staff controls the stapler to extend the limiting soft shaft 310 above one side of the cut human tissues, and at the same time, extends the fixing plate 314 above one side of the cut human tissues, thereby fixing the cut human tissues on the support base 37, so that the cut human tissues can be taken out together with the stapler, thereby effectively avoiding the situation where the tweezers pierce the anastomosis, thereby increasing the safety when using the stapler.

[0039] Further, such as Figure 1-3 As shown, the anastomosis mechanism 2 also includes a body 21, which is fixedly mounted on the other end of the slender body 1. The body 21 is communicated with the slender body 1, and a motor 22 is fixedly mounted inside the body 21. A coupling 23 is fixedly mounted on the shaft of the motor 22, and a power shaft 24 is fixedly mounted on the coupling 23. The axis of the power shaft 24 coincides with the axis of the motor 22 shaft, and the power shaft 24 extends into the slender body 1.

[0040] After the nail box 25 and the nail seat 27 are pressed and fixed at the matching position, the motor 22 is started, the motor 22 drives the coupling 23 to rotate, and the coupling 23 drives the power shaft 24 to rotate.

[0041] Further, such as Figure 2-4 As shown, the nail box 25 is communicated with the slender body 1 , the power shaft 24 extends into the nail box 25 , a rotating shaft 26 is rotatably fitted on the nail box 25 , a nail seat 27 is fixedly mounted on the rotating shaft 26 , and the rotating shaft 26 passes through the nail seat 27 .

[0042] When the anastomosis is squeezed and fixed, the stapler is controlled to drive the rotating shaft 26 to rotate, and the rotating shaft 26 drives the nail seat 27 to rotate, so that the nail seat 27 rotates toward the nail box 25, so that the nail box 25 and the nail seat 27 are closed, so as to squeeze and fix the anastomosis.

[0043] Further, such as Figure 3-4 As shown, a slide 28 is fixedly installed in the nail box 25, and a sliding member 29 is slidably matched on the slide 28. The sliding member 29 passes through the slide 28, and a screw 210 is provided on the sliding member 29. The screw 210 passes through the sliding member 29, and the screw 210 is meshed with the sliding member 29. The screw 210 is connected to the power shaft 24. A matching block 211 is fixedly installed on the bottom end of the sliding member 29. The matching block 211 is slidably matched with the bottom surface of the nail box 25, and a cutting knife 212 is fixedly installed on the matching block 211. A through opening is opened at the bottom end of the nail box 25, and the cutting knife 212 passes through the through opening of the nail box 25.

[0044] Among them, as the power shaft 24 rotates, the power shaft 24 drives the screw 210 to rotate, the screw 210 drives the sliding member 29 to move on the slide 28, the sliding member 29 drives the anastomosis block 211 to move, the anastomosis block 211 drives the cutting knife 212 to move, so that the cutting knife 212 cuts the anastomosis part, and at the same time the anastomosis block 211 pushes the anastomosis staples in the staple box 25 to perform the anastomosis process.

[0045] Further, such as Figure 1 , Figure 5 , Figure 6 As shown, the clamping mechanism 3 also includes an isolation box 31, which is fixedly installed at the bottom of the nail seat 27, and the rotating shaft 26 passes through the wall of the isolation box 31. The bottom end of the isolation box 31 is an open mouth, and a first coupling shaft 32 is rotatably matched in the isolation box 31. A toothed belt 33 is tensioned on the first coupling shaft 32 and the rotating shaft 26. A plurality of second coupling shafts 34 are rotatably matched in the isolation box 31, and the second coupling shafts 34 are symmetrically distributed, and the second coupling shafts 34 are perpendicular to the first coupling shaft 32. A plurality of bevel gears 35 are fixedly installed on the first coupling shaft 32, and the bevel gears 35 are symmetrically distributed. A helical gear 36 is fixedly installed on the second coupling shaft 34, and the helical gears 36 are meshed with the bevel gears 35.

[0046] Furthermore, the bevel gear 35 is larger than the helical gear 36 , so that the rotation angle of the rotating shaft 26 is sufficient to drive the supporting frame 37 to rotate out from the bottom of the base 27 .

[0047] When the rotating shaft 26 drives the nail seat 27 to rotate, the rotating shaft 26 drives the toothed belt 33 to rotate, the toothed belt 33 drives the first coupling shaft 32 to rotate, the first coupling shaft 32 drives the bevel gear 35 to rotate, the bevel gear 35 drives the helical gear 36 to rotate, and the helical gear 36 drives the second coupling shaft 34 to rotate.

[0048] Further, such as Figure 6-7 As shown, a support base 37 is fixedly installed on the first coupling shaft 32, and the support base 37 and the open mouth of the isolation box 31 are located in the same horizontal plane. A guide member 38 is fixedly installed on the support base 37, and one end of the guide member 38 is opposite to one side surface of the support base 37, and the other end of the guide member 38 is opposite to the other side surface of the support base 37. Both ends of the guide member 38 are open ends. A first electric telescopic rod 39 is fixedly installed on one side surface of the support base 37, and the first electric telescopic rod 39 is opposite to one end of the guide member 38. A limiting soft shaft 310 is fixedly installed on the extension rod of the first electric telescopic rod 39, and the limiting soft shaft 310 runs from one end of the guide member 38 to the other end of the guide member 38.

[0049] As the second coupling shaft 34 rotates, the second coupling shaft 34 drives the support frame 37 to rotate, so that the support frame 37 rotates to a position in contact with human tissue, that is, the support frame 37 rotates to a horizontal position.

[0050] Further, such as Figure 6-7 As shown, an iron layer 311 is fixedly installed on the limiting flexible shaft 310, and the iron layer 311 is located on the other side of the supporting base frame 37. A magnet layer 312 is fixedly installed on the supporting base frame 37. After the limiting flexible shaft 310 drives the iron layer 311 to move, the iron layer 311 is attracted by the magnet layer 312. A second electric telescopic rod 313 is fixedly installed on the guide member 38, and the second electric telescopic rod 313 is located on the other side of the supporting base frame 37. A fixing plate 314 is fixedly installed on the extension rod of the second electric telescopic rod 313.

[0051] Further, such as Figure 7-8 As shown, a controller 315 is fixedly installed in the body 21, and the controller 315 is signal-connected to the first electric telescopic rod 39, and the controller 315 is signal-connected to the second electric telescopic rod 313. A control end of the controller 315 is provided with a plurality of sliding control switches 316, and the sliding control switches 316 penetrate the wall of the body 21, and the sliding control switches 316 are used to control the switches of the first electric telescopic rod 39 and the second electric telescopic rod 313.

[0052] According to the subjective judgment of the medical staff, the sliding control switch 316 is controlled to move, and the sliding control switch 316 enables the controller 315 to control the first electric telescopic rod 39 and the second electric telescopic rod 313 on the same side to start, so that the first electric telescopic rod 39 and the second electric telescopic rod 313 on the side of the cut human tissue are started, and the first electric telescopic rod 39 pushes the limit flexible shaft 310 to move, and the limit flexible shaft 310 passes through the guide limit of the guide member 38, so that the limit flexible shaft 310 extends to the top of the human tissue at the anastomosis, and at the same time, the limit flexible shaft 310 drives the iron layer 311 The iron layer 311 moves, and after the limiting flexible shaft 310 moves, the iron layer 311 moves to be adjacent to the magnet layer 312, so that the magnet layer 312 generates a greater suction force on the iron layer 311, thereby pushing the iron layer 311 against the human tissue, so that the limiting flexible shaft 310 forms a restriction on the human tissue, and at the same time the second electric telescopic rod 313 pushes the fixing plate 314 to move, so that the fixing plate 314 is close to the human tissue to press the human tissue against the supporting base frame 37, so that the cut human tissue is fixed on the supporting base frame 37 and is taken out together with the stapler when the medical staff takes out the stapler.

[0053] Working principle:

[0054] The medical staff first takes the stapler and extends the slender body 1 to the anastomosis, aligns the nail box 25 with the nail seat 27 and places them at the anastomosis, so that the nail box 25 is located above the anastomosis and the nail seat 27 is located below the anastomosis. Then the medical staff controls the stapler to rotate the nail seat 27 relative to the nail box 25 to close the nail seat 27 and the nail box 25 to squeeze and fix the anastomosis. At the same time, the rotation of the nail seat 27 drives the support frame 37 to rotate synchronously, so that the support frame 37 rotates out from the bottom of the nail seat 27 to both sides to support the human tissues on both sides of the anastomosis. The medical staff starts the stapler to make the nail box 25 and the nail seat 27 cooperate to align the anastomosis. The cutting and anastomosis process is performed, and then after the medical staff's subjective judgment, if human tissue on one side of the anastomosis is cut off after the cutting and anastomosis, the medical staff controls the stapler to extend the limiting soft shaft 310 above the side of the cut human tissue, so that the limiting soft shaft 310 is moved to the top of the side of the cut human tissue, and is clamped with the support base 37 to limit the cut human tissue. At the same time, the medical staff controls the stapler to extend the fixing plate 314 above the side of the cut human tissue, so that the fixing plate 314 presses the cut human tissue against the support base 37 to form a fixed After the anastomosis, the nail box 25 is separated from the nail seat 27, and the support frame 37 is synchronously retracted to the bottom of the nail seat 27. Because the limiting soft shaft 310 limits the cut human tissue, the fixing plate 314 fixes the cut human tissue, so that the cut human tissue is retracted to the bottom of the nail seat 27 along with the support frame 37, and when the medical staff retracts the stapler, the cut human tissue is taken out together. When the nail box 25 and the nail seat 27 are anastomosed, the rotation of the nail seat 27 drives the support frame 37 to rotate synchronously, so that the support frame 37 is rotated out from the bottom of the nail seat 27 to both sides, The human tissues on both sides of the anastomosis are supported, and after the cutting and anastomosis process, after subjective judgment by the medical staff, if human tissues on one side of the anastomosis are cut off after the cutting and anastomosis, the medical staff controls the stapler to extend the limiting soft shaft 310 above one side of the cut human tissues, and at the same time extends the fixing plate 314 above one side of the cut human tissues, so that the cut human tissues are fixed on the supporting base frame 37, so that the cut human tissues can be taken out together with the stapler, effectively avoiding the situation that the forceps pierce the anastomosis, and increasing the safety when using the stapler;

[0055] When the anastomosis is squeezed and fixed, the stapler is controlled to drive the rotating shaft 26 to rotate, and the rotating shaft 26 drives the nail seat 27 to rotate, so that the nail seat 27 rotates toward the nail box 25, so that the nail box 25 and the nail seat 27 are closed, so as to squeeze and fix the anastomosis;

[0056] After the staple box 25 and the staple holder 27 are pressed and fixed at the anastomosis, the motor 22 is started, the motor 22 drives the coupling 23 to rotate, the coupling 23 drives the power shaft 24 to rotate, and as the power shaft 24 rotates, the power shaft 24 drives the screw 210 to rotate, the screw 210 drives the sliding member 29 to move on the slide 28, the sliding member 29 drives the anastomosis block 211 to move, the anastomosis block 211 drives the cutting knife 212 to move, so that the cutting knife 212 cuts the anastomosis, and at the same time the anastomosis block 211 pushes out the staples in the staple box 25 to perform anastomosis.

[0057] Then, as the rotating shaft 26 drives the nail seat 27 to rotate, the rotating shaft 26 drives the toothed belt 33 to rotate, the toothed belt 33 drives the first coupling shaft 32 to rotate, the first coupling shaft 32 drives the bevel gear 35 to rotate, the bevel gear 35 drives the helical gear 36 to rotate, the helical gear 36 drives the second coupling shaft 34 to rotate, and as the second coupling shaft 34 rotates, the second coupling shaft 34 drives the support frame 37 to rotate, so that the support frame 37 rotates to a position where it is in contact with human tissue, that is, the support frame 37 rotates to a horizontal position;
