Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an appendix and mesentery double cutting and closing device. Background Art

[0002] A linear stapler, also known as a digestive tract closing device, is a device that can drive multiple staggered staples into tissue in a straight line, and is also one of the devices widely used to replace manual linear suturing. It is mainly used for suturing and closing the stumps of the stomach, duodenum, small intestine, and colon, and is a full-layer everted suture.

[0003] Currently, there is a drawback in traditional linear staplers, that is: the operating skills of doctors vary, and the surgical methods are inconsistent. When removing the appendix, it is necessary to remove the mesentery and the appendix at the same time, and the stapling heights of the appendix and the mesentery are different. Therefore, traditional staplers have limitations in removing the appendix and the mesentery. Moreover, when replacing the staple cartridge in traditional staplers, it is connected by snap fit, which is not very convenient to remove.

[0004] After retrieval, it is found that the prior art publication number is CN102599954B, which discloses a linear cutting and stapling device with a double safety mechanism, which can load a linear cutting element and perform surgical suturing and cutting at the same time. It includes a closing safety mechanism, a firing safety mechanism, a left side plate, a partition plate, a driving plate, a gasket, a right side plate, a housing, a closing handle, a firing handle assembly, a left support plate, and a right support plate; the linear cutting and stapling device can load or remove a linear cutting element; the closing safety mechanism includes a push button, a thimble seat, a pin 1, a closing safety component, a torsion spring, and a thimble; the closing safety component is connected to the torsion spring by pin 1, and the hook on the closing safety component prevents the partition plate from moving through the torsion force of the torsion spring; the firing safety mechanism includes a reed, a pin 2, and a firing safety block, and the firing safety block is connected to the reed by pin 2, and the hook on the firing safety block prevents the driving plate from moving through the elastic force of the reed.

[0005] Therefore, based on the above retrieval and in combination with the existing ones, when the above solution is used, the stapling height of the titanium alloy staples inside the staple cartridge cannot be controlled. Therefore, when removing the mesentery and the appendix, the stapling height will be unified, which may cause damage to the appendix or the mesentery. The time for replacing the staple cartridge of traditional staplers is slow. To solve the problems of unified stapling height when removing the mesentery and the appendix and slow time for replacing the staple cartridge of traditional staplers, we hereby propose an appendix and mesentery double cutting and closing device. Summary of the Invention

[0009] A moving block is slidably connected to the inner wall of the clamping box, one side of the moving block is fixedly connected with a blade for cutting the appendix mesentery, the clamping block and the clamping box can rotate in opposite directions to clamp and fix the appendix and the mesentery, a staple cartridge is slidably connected to the inside of the clamping box, a disassembly mechanism for disassembling the staple cartridge is installed on the inner wall of the clamping box, and a thrust mechanism for providing thrust to the blade is slidably installed on the outer surface of the fixing tube, and the thrust mechanism can provide thrust to the blade to cut the appendix and the mesentery.

[0010] As a further improvement of this solution, the power mechanism includes a motor, the motor is fixedly installed on the inner wall of the housing, the output end of the housing is fixedly connected with a gear, and a slide plate is slidably connected to the inner wall of the housing.

[0011] As a further improvement of this solution, one end of the slide plate is fixedly connected with the fixing rod, and a rack is fixedly connected to the bottom of the slide plate, and the rack meshes with the gear.

[0012] As a further improvement of this solution, the thrust mechanism includes a slider, the slider is slidably connected to the inner wall of the fixing tube, push chutes are opened on both sides of the inner wall of the fixing tube, the outer surface of the slider is fixedly connected with a sliding tube, one end of the slider abuts against the fixing rod, a tension spring for resetting the slider is sleeved on the outer surface of the fixing rod, one end of the tension spring is fixedly connected with the slider, and the end of the tension spring away from the slider is fixedly connected with the inner wall of the fixing tube;

[0013] As a further improvement of this solution, a push rod is fixedly connected to the end of the slider away from the fixing rod, a limiting spring for resetting the inclined wall is fixedly connected to the end of the sliding tube away from the slider, a funnel tube is fixedly connected to the end of the limiting spring away from the sliding tube, the funnel tube is slidably connected to the outer surface of the fixing tube, and the limiting spring is sleeved on the outer surface of the fixing tube.

[0014] As a further improvement of this solution, an elastic torsion spring for facilitating the reset of the clamping block and the clamping box is installed between the clamping block, the clamping box and the fixed pipe.

[0015] As a further improvement of this solution, the disassembly mechanism includes a telescopic rod, one side of which is fixedly connected to the inner wall of the clamping box, and a contraction arm is fixedly connected to the inner wall of the clamping box.

[0016] As a further improvement of this solution, a reset spring is fixedly installed inside the contraction arm, a pulling column is fixedly connected to the inner wall of the contraction arm, and the reset spring is sleeved on the outer surface of the pulling column.

[0017] As a further improvement of this solution, two installation chutes for conveniently fixing the staple cartridge are provided inside the clamping box.

[0018] As a further improvement of this solution, several nail forming grooves are provided at the bottom of the clamping block, which can bend the titanium alloy nails inside the staple cartridge by abutting.

[0019] Compared with the prior art, the present invention provides an appendix and mesentery double cutting and closing device, which has the following beneficial effects:

[0020] 1. For this appendix and mesentery double cutting and closing device, when the titanium alloy nails inside the staple cartridge suture the appendix, since the nail forming height of the titanium alloy nails is inconsistent with the nail forming height of the mesentery during the suture of the cecum, the thickness of the closed appendix cecum during suture is thicker than the thickness of the mesentery after suture. Therefore, the nail forming height of the titanium alloy nails is high, and the nail forming height of the mesentery suture is low. So the heights of the mesentery abutting block and the appendix abutting block are inconsistent. Therefore, when the mesentery abutting block and the appendix abutting block abut against the titanium alloy nails inside the staple cartridge, the titanium alloy nails abut against the nail groove and deform, which can fix the appendix and the mesentery.

[0021] 2. For this appendix and mesentery double cutting and closing device, since the traditional stapler is fixed by a clamping method when installing the staple cartridge, an inclined groove is provided on the staple cartridge, and then the staple cartridge is inserted into the clamping box through the installation chute. When the inclined groove of the staple cartridge abuts against the limit block, at this time, the telescopic rod is abutted by the staple cartridge, and the telescopic spring is compressed and contracted. When the limit block moves away from the abutment of the inclined groove, the control of the staple cartridge is released, and the telescopic spring will abut against the staple cartridge, clamping the staple cartridge with the contraction arm for fixation. When the appendix resection is completed, it is rather troublesome for medical staff to remove the staple cartridge. By pulling the handle, the handle drives the contraction arm and the limit block to contract, leaving the abutment of the telescopic rod. The telescopic spring inside the telescopic rod will directly reset, ejecting the staple cartridge, and the removal of the staple cartridge is simple and fast. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes an appendix and mesentery double cutting and closing device.

[0043] Embodiment 1: Please refer to Figure 1-6 As shown, an appendix and mesentery double cutting and closing device includes a housing 2. A fixing rod 6 is slidably connected to the inner wall of the housing 2. One end of the fixing rod 6 is provided with a power mechanism 101 that can control the left and right movement of the fixing rod 6. The power mechanism 101 is fixedly installed inside the housing 2. A handle 3 is installed at the bottom of the housing 2. A storage battery that can supply power to the power mechanism 101 is fixedly installed inside the handle 3. A switch 8 that can rotate and reset is rotatably connected to the bottom of the housing 2. The setting of the handle 3 can facilitate the medical staff to control the position of the housing 2. The storage battery can effectively provide power for the power mechanism 101, enabling the medical staff to freely adjust the position of the housing 2 during work, reducing the limitation of the working site. The setting of the switch 8 can enable the medical staff to cooperate with the handle 3, facilitating the staff to better grasp when in use. The left end face of the housing 2 is fixedly connected with a fixing tube 15 that can limit the fixing rod 6. The outer surface of the fixing rod 6 is slidably connected to the inside of the fixing tube 15. One end of the fixing tube 15 away from the housing 2 is rotatably connected with a clamping block 22 and a clamping box 23;

[0044] Please refer to Figure 9, a moving block 31 is slidably connected to the inner wall of the clamping box 23. A blade 24 capable of cutting the mesoappendix is fixedly connected to one side of the moving block 31. The clamping block 22 and the clamping box 23 can rotate in opposite directions to clamp and fix the appendix and the mesentery. The clamping block 22 and the clamping box 23 are symmetrically installed up and down. A staple cartridge 25 is slidably connected in the clamping box 23. Specifically, an installation cavity is provided inside the clamping box 23, and the staple cartridge 25 is slidably connected in the installation cavity. When the clamping block 22 and the clamping box 23 rotate towards each other, the appendix and the mesentery can be clamped and fixed. A disassembly mechanism 201 for detachably fixing the staple cartridge 25 is installed on the inner wall of the clamping box 23. A thrust mechanism 301 capable of providing a thrust to the blade 24 is slidably installed on the outer surface of the fixed tube 15. The thrust mechanism 301 can provide a thrust to the blade 24 to cut the appendix and the mesentery.

[0045] Embodiment 2: Please refer to Figure 2-3 As shown, the power mechanism 101 includes a motor 7. The motor 7 is fixedly installed on the inner wall of the housing 2. The output end of the housing 2 is fixedly connected to a gear 11. Two groups of power slide rails 10 are provided on the inner wall of the housing 2. A slide plate 5 is slidably connected to the inner wall of the power slide rail 10. The power slide rail 10 is provided at both ends of the inner wall of the housing 2. The slide plate 5 slides on the inner wall of the power slide rail 10. The power slide rail 10 can limit the slide plate 5 to prevent the slide plate 5 from shaking during use and affecting the use by medical staff. One end of the slide plate 5 is fixedly connected to a fixed rod 6. A rack 4 is fixedly connected to the bottom of the slide plate 5. The rack 4 meshes with the gear 11.

[0046] Please refer to Figure 3-7As shown, the thrust mechanism 301 includes a slider 16. The slider 16 is slidably connected inside a fixed tube 15. On both sides of the inner wall of the fixed tube 15, there are provided pushing chutes 13. On both sides of the slider 16, there are fixedly connected limited displacement blocks 39. The outer surface of the limited displacement block 39 is slidably connected to the inner wall of the pushing chute 13. The outer surface of the limited displacement block 39 is fixedly connected to the sliding tube 1. The limited displacement blocks 39 fixedly connected to both sides of the slider 16 slide on the inner wall of the pushing chute 13. When the slider 16 is pushed by the fixed rod 6, the limited displacement block 39 can limit the slider 16 to ensure that the slider 16 will not rotate under the action of the limited displacement block 39 when being pushed by the fixed rod 6. Both sides of the slider 16 are in contact with the fixed rod 6. A tension spring 14 for resetting the slider 16 is sleeved on the outer surface of the fixed rod 6. One end of the tension spring 14 is fixedly connected to the slider 16, and the end of the tension spring 14 far from the slider 16 is fixedly connected to the inner wall of the fixed tube 15. One end of the slider 16 far from the fixed rod 6 is fixedly connected to a push rod 17. A number of limited sliding pieces 18 are fixedly connected to the outer surface of the push rod 17. The outer surface of the limited sliding piece 18 is in contact with the inner wall of the fixed tube 15. The limited sliding piece 18 can effectively limit the position of the push rod 17 to keep the push rod 17 always in the middle inside the fixed tube 15. When the push rod 17 is pushed, one end of the push rod 17 always contacts the middle of the moving block 31, so that the moving block 31 can be pushed better. One end of the sliding tube 1 far from the gear 11 is fixedly connected to a limit spring 38. One end of the limit spring 38 far from the sliding tube 1 is fixedly connected to a funnel tube 21. The funnel tube 21 is slidably connected to the outer surface of the fixed tube 15. An inclined wall 20 is provided inside the funnel tube 21. The inclined wall 20 can accommodate one end of the clamping block 22 in contact with the clamping box 23. The tension spring 14 is sleeved on the outer surface of the fixed tube 15.

[0047] Please refer to Figure 8-9 As shown, on the inner wall of the clamping box 23, there is provided a moving chute 28 for limiting the sliding of the moving block 31. The moving block 31 is slidably connected to the inner wall of the moving chute 28. The moving chute 28 can limit the moving block 31 during sliding to prevent the moving block 31 from shaking and shifting during movement. On both the front and back sides of the moving block 31, there are fixedly connected a mesentery abutting block 30 and an appendix abutting block 29. The heights of the mesentery abutting block 30 and the appendix abutting block 29 are different. When the titanium alloy nails in the staple cartridge 25 suture the appendix, since the nail-forming height of the titanium alloy nails during the suture of the cecum is inconsistent with the nail-forming height of the mesentery, the thickness of the closed part during the suture of the appendix and cecum is thicker than the thickness after the suture of the mesentery. The nail-forming height of the titanium alloy nails is high, and the nail-forming height of the mesentery suture is low, so the heights of the mesentery abutting block 30 and the appendix abutting block 29 are inconsistent.

[0048] Please refer to Figure 6 、 10As shown, an elastic torsion spring 32 for facilitating the reset of the clamping block 22 and the clamping box 23 is installed between the clamping block 22 and the clamping box 23 and the fixed pipe 15. Specifically, one end of the two groups of elastic torsion springs 32 is fixedly connected to the outer surface of the fixed pipe 15, and the ends of the two groups of elastic torsion springs 32 far from the fixed pipe 15 are fixedly connected to the clamping block 22 and the clamping box 23 respectively.

[0049] Please refer to Figure 8 、 11 、12 as shown, the disassembly mechanism 201 includes a telescopic rod 26. One side of the telescopic rod 26 is fixedly connected to the inner wall of the clamping box 23. A telescopic spring 33 is fixedly installed inside the telescopic rod 26. A contraction arm 27 is fixedly connected to the inner wall of the clamping box 23. A limit clamping block 34 is fixedly connected to the top of the contraction arm 27. A reset spring 35 is fixedly installed inside the contraction arm 27. A pulling column 36 is fixedly connected to the inner wall of the contraction arm 27. The reset spring 35 is sleeved on the outer surface of the pulling column 36. One end of the pulling column 36 far from the contraction arm 27 is rotatably connected to a handle 19. A reset torsion spring 12 for resetting the handle 19 is installed between the handle 19 and the pulling column 36. Specifically, one end of the reset torsion spring 12 is fixedly connected to the pulling column 36, and the end of the reset torsion spring 12 far from the pulling column 36 is fixedly connected to the handle 19. When medical staff needs to pull the pulling column 36, the handle 19 can facilitate the staff to pull the pulling column 36 better, and the reset torsion spring 12 can reset the handle 19. Two inclined slots 9 for facilitating the fixation of the staple cartridge 25 are opened inside the clamping box 23, and two installation chutes 40 for facilitating the fixation of the staple cartridge 25 are opened inside the clamping box 23.

[0050] Please refer to Figure 13 、 14 As shown, a plurality of nail forming grooves 37 for bending the titanium alloy nails inside the staple cartridge 25 by abutting are provided at the bottom of the clamping block 22.

[0051] Working principle of the present invention: When in use, when it is necessary to excise the appendix and mesentery, hold the handle 3 with the hand, align the clamping block 22 with the clamping box 23 at the boundary between the appendix and the mesentery, place the mesentery abutting block 30 above the appendix, and make the appendix abutting block 29 located at the mesentery. Start the motor 7, and the motor 7 will drive the gear 11 to rotate. The gear 11 drives the rack 4 to move. The rack 4 will drive the sliding plate 5 and the fixed rod 6 to move. The fixed rod 6 will abut against the slider 16, and the slider 16 is pushed by the fixed rod 6 to move. The slider 16 drives the push rod 17 and the sliding tube 1 to move. When the sliding tube 1 moves, it will drive the funnel tube 21 to move. Since there is a certain distance between the end of the push rod 17 close to the blade 24, when the funnel tube 21 contacts the clamping block 22 and the clamping box 23, the clamping block 22 and the clamping box 23 will move in opposite directions to clamp the appendix and the mesentery. When the sliding tube 1 moves again and the funnel tube 21 is blocked by the clamping block 22 and cannot move, since a tension spring 14 is provided between the sliding tube 1 and the funnel tube 21, when the sliding tube 1 continues to move, the tension spring 14 contracts, and the push rod 17 will drive the moving block 31 to move. The moving block 31 drives the blade 24, the appendix abutting block 29 and the mesentery abutting block 30 to move. The mesentery abutting block 30 and the appendix abutting block 29 will abut against the titanium alloy nails inside the staple cartridge 25 to suture the mesentery and the appendix;

[0052] When the titanium alloy nails inside the staple cartridge 25 suture the appendix, since the forming height of the titanium alloy nails during cecal suture is inconsistent with the forming height of the mesentery, the closed thickness during appendix-cecum suture is thicker than the thickness after mesentery suture. Therefore, the forming height of the titanium alloy nails is high and the forming height of the mesentery suture is low. Thus, the heights of the mesentery abutting block 30 and the appendix abutting block 29 are inconsistent. When the mesentery abutting block 30 and the appendix abutting block 29 abut against the titanium alloy nails inside the staple cartridge 25, the titanium alloy nails abut against the forming groove 37 and deform, which can fix the appendix and the mesentery;

[0053] Since the traditional stapler fixes the staple cartridge 25 by a snap-fit method, a chute 9 is provided on the staple cartridge 25, and then the staple cartridge 25 is inserted into the clamping box 23 through the installation chute 40. When the chute 9 of the staple cartridge 25 abuts against the limit block 34, at this time, the telescopic rod 26 is abutted by the staple cartridge 25, and the telescopic spring 33 is compressed and contracted. When the limit block 34 moves away from the abutment of the chute 9, the control of the staple cartridge 25 is released, and the telescopic spring 33 will abut against the staple cartridge 25, so that the staple cartridge 25 is clamped by the contraction arm 27 for fixation. When the appendix excision is completed, it is rather troublesome for medical staff to remove the staple cartridge 25. By pulling the handle 19, the handle 19 drives the contraction arm 27 and the limit block 34 to contract and move away from the abutment of the telescopic rod 26. The telescopic spring 33 inside the telescopic rod 26 will directly reset and eject the staple cartridge 25, making the removal of the staple cartridge 25 simple and fast;

[0054] When the excision is completed, the fixed rod 6 retracts, the fixed rod 6 will leave the abutment of the push rod 17, and the tension spring 14 will pull the slider 16 and the push rod 17 to reset.

[0055] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
