[0024] The present invention provides a description of a stapler with a tissue protective sheath according to an embodiment of the present invention. Please refer to [link / reference]. Figures 1 to 4A stapler with a tissue protective sheath includes a stapler body 1, a staple cartridge 6, and an anvil 5. The anvil 5 is engaged with the output end of the stapler body 1. The staple cartridge 6 is fixedly connected to the outer wall of the stapler body 1, and is located on the outer wall of the output end of the stapler body 1. A base 15 is fixedly connected inside the anvil 5. A mating seat 12 is fixedly connected to the outer wall of the base 15. A cutting anvil 11 is rotatably connected to the outer wall of the mating seat 12. Two mating anvil grooves 16 are provided inside the base 15, and the two mating anvil grooves 16 are arranged centrally symmetrically. The cutting anvil 11 is located inside the base 15. The wall is symmetrically fixed with two mating blocks 20, which are slidably connected within the mating ring groove 16. A pair of mating slots 13 are symmetrically provided inside the mating seat 12, and each slot 13 is connected to the mating ring groove 16. The two mating blocks 20 are slidably connected inside the mating slots 13. A placement groove 19 is provided inside the anvil seat 5, and a tissue protection film 8 is placed inside the placement groove 19. The tissue protection film 8 is made of medical-grade PET polyester, with its winding end located within the placement groove 19 and its working end extending to cover the outer wall of the anvil seat 5. By providing the tissue protection film 8 on the anvil seat 5 and its corresponding use with the placement groove 19, the tissue protection film 8 can be quickly and temporarily installed before surgery, ensuring its service life. After intestinal anastomosis surgery, the installed tissue protection film 8 can also cover and protect the intestinal circumferential incision, reducing the risk of subsequent wound infection.

[0025] In this embodiment of the utility model, please refer to Figures 1 to 4 Each of the two mating annular grooves 16 has a mating pad 9 fixedly connected to it, and two mating blocks 20 are slidably connected to the outer wall of the mating pad 9. Through the mating pad 9 and its mating relationship with the mating blocks 20, the mating blocks 20 can be installed into the mating annular groove 16; the mating pad 9 can make the mating blocks 20 relatively fixed in the mating annular groove 16, ensuring the structural stability of the cutting anvil 11 after installation.

[0026] In this embodiment of the utility model, please refer to Figures 1 to 4 A puncture needle sleeve 7 is fixedly connected to the upper surface of the mating seat 12. A suture binding groove 14 is provided inside the puncture needle sleeve 7, located at the middle position of the sleeve. By setting the puncture needle sleeve 7 and the suture binding groove 14, the suture after suturing can be bound within the suture binding groove 14 of the puncture needle sleeve 7, placing the intestine during the anastomosis procedure in a fixed position relative to the anvil 17 located inside the anvil seat 5.

[0027] In this embodiment of the utility model, please refer to Figures 1 to 4An anvil 17 is fixedly connected inside the anvil seat 5, and the anvil 17 has an anastomosis groove 18 inside. By setting the anvil 17 and the anastomosis groove 18, it is convenient for the anastomosis staple to pass through the anvil 17 to staple the two ends of the intestine and the tissue protection membrane 8 together during the anastomosis operation.

[0028] In this embodiment of the utility model, please refer to Figures 1 to 4 The cutting anvil 11 is internally fixedly connected to a handle 10. There are two handles 10, which are symmetrically arranged with the cutting anvil 11 as the center. The handles 10 facilitate the rotation of the cutting anvil 11.

[0029] In this embodiment of the utility model, please refer to Figures 1 to 4 A fixed handle 2 is fixedly connected to the end of the stapler body 1 away from the staple cartridge 6, and an adjustment knob 3 is rotatably connected to the end of the fixed handle 2 away from the stapler body 1. The fixed handle 2 makes it easy to pick up the present invention; the adjustment knob 3 makes it easy to adjust the extension and retraction of the puncture needle at the output end of the stapler body 1.

[0030] In this embodiment of the utility model, please refer to Figures 1 to 4 A firing handle 4 is rotatably connected to the lower surface of the stapler body 1, and a safety pin is provided at the rotatable connection between the firing handle 4 and the stapler body 1. By setting the firing handle 4 and the safety pin, it is convenient to fire the staples and circumferential cutter in the staple cartridge 6 through the firing handle 4.

[0031] Working principle: When using this utility model, it is opened and taken out of the disposable sterilization and sealing device. By rotating the adjustment knob 3 counterclockwise, the anvil 5 at the output end of this utility model is slowly pushed out. The anvil 5 is removed and then taken out. The cutting anvil 11 is rotated by the handle 10 on the cutting anvil 11, so that the mating block 20 on the cutting anvil 11 is rotated into the mating slot 13. The cutting anvil 11 is taken out, and then the tissue protective film 8 in the disposable sterilization and sealing device is taken out and placed into the placement slot 19. Then, the working extension end of the tissue protective film 8 is stretched out so that the extension end of the tissue protective film 8 covers the outer wall of the anvil 5. Then, the cutting anvil 11 is reinstalled. The reinstalled cutting anvil 11 covers and shields the rolled-up section of the tissue protective film 8 in the placement slot 19.

[0032] After completing the above operations, the anvil 5 is placed in the patient's intestine along the surgical wound and moved until the puncture needle and sleeve 7 extend beyond the patient's anastomosis position. Then, the intestine at the anastomosis position is sutured with surgical sutures, and the sutures are tied in the suture tying groove 14 of the puncture needle and sleeve 7.

[0033] Then, the output end of the stapler body 1 is inserted into the intestine on the other side of the anastomosis surgery. Then, the adjustment knob 3 is slowly turned clockwise so that the puncture needle at the output end of the stapler body 1 penetrates the intestine. Then, the protruding puncture needle is inserted into the puncture needle sleeve 7 to complete the connection between the anvil seat 5 and the stapler body 1.

[0034] Then, slowly rotate the adjustment knob 3 counterclockwise, causing the puncture needle of the stapler body 1 to slowly retract, driving the anvil 5 and the intestine at the anastomosis site to retract to the anastomosis site until the anvil 5 is pressed against the staple cartridge 6. Then, by pulling the firing handle 4, the push rod in the staple cartridge 6 pushes the staples and cutting blade in the staple cartridge 6 against the anvil 5. The fired staples staple together the two ends of the intestine and the tissue protection membrane 8. The fired cutting blade makes a circumferential cut of the stapled intestine. Then, slowly remove the stapler body 1, so that the anvil 5 slowly passes through the circumferential cut between the two ends of the intestine. During this process, the tissue protection membrane 8 stapled to the inner wall of the intestine is slowly brought out and covered on the circumferential cut, completing the intestinal anastomosis surgery.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
