[0040] In the present embodiment, the electric laparoscopic stapler gun barrel firing force detection device also includes a mounting plate 60, and the positioning frame 20, the first force measuring part 30, the second force measuring part 40 and the control panel 50 are all arranged on the mounting plate 60. The mounting plate 60 is provided with a first position switch 61 and a second position switch 62. The first position switch 61 limits the first force measuring part 30, and the second position switch 62 limits the second force measuring part 40.

[0041] like Figure 3 As shown, the gun body 10 of this embodiment includes an outer tube 11, a nail seat 12 and a firing rod 13. After the outer tube 11 is driven, the outer tube 11 will close the nail seat 12 to realize the detection of the closing force of the gun body 10, and after the firing rod 13 is driven by force, the firing force and the retraction force of the gun body 10 are detected.

[0042] Combination Figure 1 and Figure 4 As shown, the positioning frame 20 of this embodiment is provided with a plurality of positioning grooves 21, and the positioning frame 20 is provided with a cover plate 90. The cover plate 90 is flipped over and engaged with the positioning frame 20 to position the gun body 10. During the positioning process of the gun body 10, the entire gun body 10 is located in the positioning groove 21. After the cover plate 90 is flipped over, the preliminary positioning of the gun body 10 is completed.

[0043] In this embodiment, the closing block 34 of the first force measuring part 30 is located in the positioning frame 20 and is engaged with the outer tube 11. The closing block 34 is provided with an inner concave structure 341 to engage the outer tube 11 on the closing block 34. Therefore, the closing block 34 realizes further positioning of the gun body 10, and during the movement of the closing block 34, the outer tube 11 will be driven to move, so that the outer tube 11 drives the nail seat 12 to close, thereby realizing the detection of the closing force of the gun body 10.

[0044] Furthermore, in the present embodiment, a guide rod 70 is provided in the positioning frame 20, and a reset spring 71 is provided on the guide rod 70. The closing block 34 passes through the guide rod 70 and is connected to the reset spring 71 for guiding and resetting. During the movement of the closing block 34, the guide rod 70 guides the closing block 34 to avoid the displacement of the closing block 34 during the movement, and the reset spring 71 is provided on the guide rod 70. After the closing block 34 completes the closing force detection of the gun body 10, it drives the closing block 34 to automatically reset for subsequent operations.

[0045] Combination Figure 1 , Figure 2 as well as Figure 5 As shown, the first force measuring part 30 of the present embodiment drives the outer tube 11 to close the anvil 12 to obtain the closing force of the anvil 12, and the second force measuring part 40 drives the firing rod 13 to obtain the firing force and the retraction force of the electric laparoscopic stapler gun barrel. The control panel 50 is connected to the first force measuring part 30 and the second force measuring part 40 for control and information exchange. In the present embodiment, a timing sensor, a current sensor and a voltage sensor are added during the working process of the first force measuring part 30 and the second force measuring part 40. Therefore, while realizing the detection of closing force, firing force and retraction force, it also realizes the detection of firing time, retraction time, firing voltage, retraction voltage, firing current and retraction current, and the control panel 50 reflects each detection parameter in real time.

[0046] In the present embodiment, the first force measuring part 30 includes a push rod 31, a first dynamometer 32, a push block 33 and a closing block 34. The push rod 31, the first dynamometer 32 and the push block 33 are connected in sequence. The closing block 34 is located in the positioning frame 20 and is engaged with the outer tube 11. The push block 33 pushes the closing block 34 to drive the outer tube 11. The push rod 31 of the present embodiment is pushed manually. The pushed push rod 31 drives the first dynamometer 32. The first dynamometer 32 pushes the push block 33 so that the push block 33 gradually contacts the closing block 34. A push pin is provided on the push block 33 of the present embodiment. The closing block 34 is pushed by the push pin. The moving closing block 34 pushes the outer tube 11 of the gun body 10. The outer tube 11 drives the nail seat 12 to close. After the nail seat 12 is closed, the value displayed by the first dynamometer 32 is the closing force of the gun body 10.

[0047] Furthermore, in this embodiment, an adjustment head 80 is provided at the end of the first dynamometer 32 to change the initial position of the first dynamometer 32 . The adjustment head 80 can fine-tune the position of the first dynamometer 32 , thereby further meeting the detection requirements for the closing force of the gun body 10 .

[0048] Combination Figure 1 , Figure 2 as well as Figure 6As shown, the second force measuring part 40 of the present embodiment includes a driving motor 41, a transmission rack 42, an adapter plate 43 and a second dynamometer 44. The driving motor 41 drives the transmission rack 42. The transmission rack 42, the adapter plate 43 and the second dynamometer 44 are connected to drive the firing rod 13 through the second dynamometer 44. Under the cooperation of the driving motor 41, the transmission rack 42 and the adapter plate 43, the second dynamometer 44 is driven, and the firing rod 13 of the gun body 10 is fired by the second dynamometer 44. After the firing is completed, the second dynamometer 44 retreats, thereby completing the detection and processing of the firing force and the retreat force of the gun body 10.

[0049] In this embodiment, a limit pin is provided on the adapter plate 43, and the limit pin can contact the second position switch 62 to limit the adapter plate 43, and then realize the limit processing of the second dynamometer 44. Since the second position switch 62 is a movable switch, it can adjust the installation position on the mounting plate 60, and thus can adjust the limit stroke of the second dynamometer 44 to make it adapt to more specifications of electric laparoscopic stapler gun rods and meet the detection of various models of electric laparoscopic stapler gun rods.

[0050] Furthermore, the timing sensor, current sensor and voltage sensor of this embodiment are all installed in the control panel 50, and the time, current and voltage are detected while measuring the force.

[0051] In actual use of the electric laparoscopic stapler gun barrel firing force detection device of this embodiment, the gun body 10 is installed in the positioning frame 20, and the gun body 10 is initially positioned under the cooperation of the positioning frame 20 and the cover plate 90, and the closing block 34 of the first force measuring part 30 can cooperate with the outer tube 11 of the gun body 10, further realizing the positioning processing of the gun body 10. After the positioning of the gun body 10 is completed, the push rod 31 of the first force measuring part 30 is manually pushed, and through the first dynamometer 32, the closing block 34 pushes the outer tube 11 of the gun body 10, and the outer tube 11 pushes the nail seat 12 to close. At this time, the value displayed by the first dynamometer 32 is the closing force of the gun body 10. After the detection of the first force measuring part 30 is completed, the first dynamometer 32 is used to detect the closing force of the gun body 10. The driving motor 41 of the second force measuring part 40 makes the second dynamometer 44 approach the firing rod 13 of the gun body 10 through the transmission rack 42 and the adapter plate 43, and fires the firing rod 13. After the firing, the firing rod retracts, and the firing force and the retraction force are displayed by the second dynamometer 44, thereby completing the detection of the closing force, firing force and retraction force of the gun body 10. In addition, the timing sensor, current sensor and voltage sensor of this embodiment are all installed in the control panel 50. While measuring the force, the time, current and voltage are detected, thereby completing the detection of the closing force, firing force, retraction force, firing time, retraction time, firing voltage, retraction voltage, firing current, retraction current and other parameters of the electric laparoscopic stapler gun rod.

During the movement of the closing block 34, since the closing block 34 cooperates with the outer tube 11, the outer tube 11 is driven to move, so that the outer tube 11 pushes the anvil 12 to close. After the anvil 12 is closed, the value displayed by the first dynamometer 32 is the closing force to be measured;

[0056] S3, the driving motor 41 of the second force measuring part 40 pushes the second dynamometer 44 through the transmission rack 42 and the adapter plate 43, so that the second dynamometer 44 drives the firing rod 13, and the second dynamometer 44 obtains the firing force and the retraction force, and obtains the firing voltage, the retraction voltage, the firing current and the retraction current according to the electrical sensor.
