For example, the current cutting stapler testing equipment is mostly used for only one test and has a relatively single function. Even most of the testing equipment is general-purpose instrument and is not specifically used for cutting stapler testing, which results in low targeted testing. The cutting performance test is mostly to test the sharpness of the cutting knife, that is, the cutting knife of the cutting stapler is driven by an electronic tensile testing machine to cut the standard suture, and the sharpness is judged by testing its cutting force. However, in the normal use of the cutting stapler, the cutting object is the tissue in the human body, and the cutting process is a larger-scale continuous cutting.

DETAILED DESCRIPTION

[0025] 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.

[0026] Please see attached Figure 1 -Attached Figure 7 The embodiment of the present invention provides a cutting stapler detection device, including a detection table 1. A driving mechanism is arranged on one side of the upper surface of the detection table 1. The driving mechanism is used to clamp and drive the cutting stapler to operate, detect cutting force, and drive the cutting stapler to rise and fall. A clamp assembly is also arranged on the upper surface of the detection table 1. The clamp assembly is used to clamp and fix consumables to be cut and stapled, and detect the stapler strength of the cutting stapler. A sliding rheostat 22 is arranged in the detection table 1. The sliding rheostat 22 is used to detect the effective cutting stroke of the cutting stapler. An industrial computer 2 is arranged on one side of the driving mechanism. The industrial computer 2 is used to set and control the operating parameters of the driving mechanism and the clamp assembly, and calculate the detection result according to the feedback data of the driving mechanism, the clamp assembly, and the sliding rheostat 22.

[0027] The cooperation between the driving mechanism and the clamp assembly enables the detection device to be used for simulated cutting tests, pressure resistance tests at the anastomosis site, and cutting depth tests of the stapler, thereby achieving the effect of having multiple detection functions at the same time. This not only reduces the detection cost, but also makes the detection method more scientific.

[0028] The driving mechanism includes an electric slide 3, which is arranged in a vertical sliding direction, and its bottom wall is fixedly connected to the upper surface of the detection table 1. The sliding end of the electric slide 3 is fixedly connected to one end of the bracket 4, and the other end of the bracket 4 is fixedly connected to a pressure sensor 5. The detection end of the pressure sensor 5 is arranged vertically downward and is fixedly connected to a cutting stapler clamp 6. The cutting stapler clamp 6 is used to clamp and fix the rod of the cutting stapler, and a firing device is arranged inside it for firing the cutting stapler to operate.

[0029] The electric slide 3 is mainly used to drive the cutting stapler to rise and fall, and the structure of the cutting stapler clamp 6 is similar to the control handle structure of the cutting stapler, so that the cutting stapler clamp 6 can be used to clamp and fix the cutting stapler rod body while also controlling the cutting and stapling function.

[0030] A corrugated sleeve 7 is also provided inside the electric slide 3 to isolate the inside of the electric slide 3 from the outside.

[0031] The corrugated sleeve 7 has a foldable function, and folds up and down as the electric slide 3 moves, so that the inside of the electric slide 3 is always isolated from the outside world, avoiding the entry of external dust, thereby improving the life and accuracy of the electric slide 3.

[0032] The fixture assembly includes a fixed table 1 8 and a fixed table 2 9, which correspond to each other. The fixed table 1 8 is located at the lower left side of the electric slide 3, and the bottom wall is fixedly connected to the upper surface of the detection table 1, the top wall is fixedly connected with a nozzle 10, and the nozzle 10 tube body is sleeved with a spring clamp 11, the fixed table 2 9 is located at the lower right side of the electric slide 3, and the lower part is slidably connected in the slide groove 12, the slide groove 12 is embedded in and fixedly connected to the upper part of the detection table 1, the top wall of the fixed table 2 9 is fixedly connected with a nozzle 2 13, and the nozzle 2 13 tube body is sleeved with a spring clamp 2 14, and the side wall of the fixed table 2 9 is also provided with a limiting device for limiting the position of the fixed table 2 9.

[0033] Since the detection consumables are not conventional sutures, but bionic anastomosis, that is, bionic tubular materials that simulate internal organs, etc., it is impossible to use conventional clamps to clamp and fix them. Therefore, spring clamp 11 and spring clamp 2 14 are used to respectively sleeve and seal the two ends of the bionic anastomosis on nozzle 10 and nozzle 2 13 to achieve clamping and fixation of the bionic anastomosis. The setting of the slide groove 12 makes it possible to adaptively adjust the distance between nozzle 10 and nozzle 2 13 according to the length of the bionic anastomosis, and then fix the adjusted position of nozzle 2 13 by a limit device to avoid affecting the detection due to excessive looseness of the bionic anastomosis.

[0034] An air channel 1 is provided in the fixed platform 8, one end of which is connected to the nozzle 10, and the other end is connected to the output end of the air pump through the air pipe 26. An air channel 2 is provided in the fixed platform 2 9, one end of which is connected to the nozzle 2 13, and the other end is connected to the output end of the air pump through the air pipe 2 27.

[0035] At the same time, after the bionic anastomosis is cut and anastomosed using a cutting stapler, in order to detect the pressure resistance of the anastomosis, air is injected into the two bionic anastomotic pieces after anastomosis from nozzles 10 and 13 through an air pump, and then the air pressure monitoring function of the air pump is used to detect the pressure resistance of the anastomosis.

[0036] A travel switch 15 is provided between the fixed platform 1 8 and the fixed platform 2 9 for controlling the operation state of the electric slide 3. The center of the travel switch 15 is located directly below the cutting stapler clamp 6, and a thread groove 1501 is provided at the center of the top wall.

[0037] The travel switch 15 is used to control the operating state of the electric slide 3. When the bottom end of the cutting stapler contacts the travel switch 15 and pushes it to start during the detection process, it means that the cutting stapler is in the lowest position. Then the travel switch 15 sends a signal to the industrial computer 2 to control the electric slide 3 to stop running, so as to avoid the cutting stapler from colliding with the detection platform 1 and being damaged.

[0038] The limiting device includes a support rod 16, one end of which is rotatably connected to the side wall of the fixed platform 29, and the other end is rotatably connected to a cross sleeve 17. The middle part of the cross sleeve 17 passes through and is slidably connected to the outer cylinder of the damping telescopic rod 18. The end face of the outer cylinder of the damping telescopic rod 18 is fixedly connected to a block 19. The outer wall of one side of the block 19 is in conflict with the side wall of the fixed platform 29, and the bottom wall on the other side is fixedly connected to a limiting tooth 20. The limiting tooth 20 corresponds to the limiting groove 1201 opened on the inner bottom wall of the slide groove 12. The output end of the damping telescopic rod 18 is rotatably connected to a handle 21, and the handle 21 and the cross sleeve 17 are magnetically attracted to each other.

[0039] The damping telescopic rod 18 is pressed down by the handle 21 to make the limiting tooth 20 embed into the limiting groove 1201, and at this time the stopper 19 conflicts with the fixed platform 2 9, so that the position of the fixed platform 2 9 is fixed. When the fixed platform 2 9 needs to be moved, the handle 21 is pulled to separate the limiting tooth 20 from the limiting groove 1201, and the fixed platform 2 9 is released from the fixed state.

[0040] A bolt 2101 is fixedly connected to the middle of the handle 21, and the bolt 2101 matches the threaded groove 1501. A through groove 1202 is also provided on the bottom wall of the slide groove 12, and a slide bar 23 is slidably connected in the through groove 1202. The top of the slide bar 23 is fixedly connected to the bottom wall of the fixed platform 29, and the bottom end is fixedly connected to the sliding piece of the sliding rheostat 22.

[0041] When the cutting depth of the cutting stapler is detected, the cutting stapler fixture 6 is first controlled by the industrial computer 2 to expand the clamping part of the cutting stapler, and the support rod 16 is rotated so that the stopper 19 is directly below the cutting stapler. Then the handle 21 is rotated to connect the bolt 2101 with the thread groove 1501, and then the cutting stapler is driven downward by the electric slide 3. When the cutting stapler contacts the stopper 19 and continues to be pressed downward, the travel switch 15 is triggered, and then the electric slide 3 stops running. At this time, the cutting stapler fixture 6 triggers the cutting stapler to continuously extend the cutting knife, and then the stopper 19 is continuously pushed downward, and then the fixed platform 29 is pushed to move through the support rod 16, and the sliding piece of the sliding rheostat 22 is synchronously driven to move. When the cutting knife is extended to the longest position, the stopper 19 stops descending, and at this time, the sliding piece of the sliding rheostat 22 also stops moving synchronously. Then, according to the feedback data of the resistance change of the sliding rheostat 22, the industrial computer 2 can calculate the overall extension length of the cutting knife.

[0042] A spring clip 24 is also sleeved on the nozzle 10 tube body, and the rotating shaft portion of the spring clip 24 is fixedly connected to the side wall of the fixed platform 8. A spring clip 25 is also sleeved on the nozzle 2 13 tube body, and the rotating shaft portion of the spring clip 25 is fixedly connected to the side wall of the fixed platform 2 9. The spring clip 1 24 and the spring clip 2 25 adopt the same structure, and the middle part of the chuck is two symmetrical semi-cylindrical shapes, and the upper and lower parts of the chuck are both symmetrical and mutually fitting flat plate structures.

[0043] Due to the fixing method of the spring clamp, the two ends of the bionic anastomosis are twisted. In order to avoid the twisting of the bionic anastomosis cutting part, the spring clamp 1 24 and the spring clamp 2 25 are further used to correct and clamp the two ends of the bionic anastomosis respectively, so that the bionic anastomosis is in a flat state, which is convenient for cutting and anastomosis.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
