Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to a surrounding detection equipment for a straight tube of an electric laparoscope stapler. Background Art

[0002] The laparoscopic stapler is one of the important instruments in laparoscopic surgery. It uses titanium nails to separate or staple tissues, replacing traditional manual suturing. It is easy and quick to operate, greatly shortening the operation time. The straight tube is an important connecting component of the electric laparoscopic stapler, which improves the transmission stability and protection capability of the internal mechanism of the electric laparoscopic stapler. The accuracy of the inner and outer diameters of the straight tube directly affects the use and assembly of the electric laparoscopic stapler. Therefore, the inner and outer diameters of the straight tube need to be tested during the production process.

Some equipment can inspect the inside and outside of the straight pipe at the same time, but can only inspect a certain position inside or outside the straight pipe. The inspection range is small, resulting in low accuracy of the inspection structure. Summary of the invention

[0018] The present invention provides a wraparound detection device for a straight tube of an electric laparoscopic stapler through improvement, which has the following improvements and advantages compared with the prior art:

[0019] First, the present invention is provided with a detection mechanism. When the straight tube is driven to move to the position of the detection rod, the second telescopic rod will be activated to drive the detection rod to move upward, and the detection rod will move to the inside of the straight tube. The inner diameter of the straight tube can be detected by the inner diameter infrared detection module, and the outer diameter infrared detection module can detect the outer diameter of the straight tube at the same time, thereby achieving the effect of simultaneously detecting the inside and outside of the straight tube;

[0020] Secondly, the present invention is provided with a positioning mechanism. When the straight tube moves to the top of the detection rod, the first telescopic rod can be started at this time, and the first telescopic rod will drive the straight tube to move downward. At this time, the straight tube will squeeze the positioning plate. After being squeezed, the positioning plate will move downward, and then squeeze the reset spring on the connecting rod. After being squeezed, the reset spring will release the elastic force, so that the straight tube can be fixed between the positioning plate and the fixing clamp by the elastic force. At this time, the second driving motor can be started, and the second driving motor drives the driving shaft and the driving gear to rotate, and the driving gear and the transmission gear ring are meshed, and then the movable plate and the positioning plate can be driven to rotate through the driving gear and the transmission gear ring, so that the straight tube will be driven to rotate. At this time, the second telescopic rod is started again, and the second telescopic rod will drive the detection rod to move to the inside of the straight tube. Since the straight tube is rotating, the detection rod moves upward inside the straight tube, and the inner diameter infrared detection module will detect the inner diameter of all positions inside the straight tube, and the outer diameter infrared detection module will also detect a circle of the outer wall of the straight tube, so as to achieve the effect of all-round detection of the straight tube, thereby improving the accuracy of detection.

[0021] Thirdly, the present invention sets a loading and unloading mechanism. When the straight tube is put into the feeding seat, the loading and unloading motor will start, and the loading and unloading motor will rotate the transmission shaft. The transmission shaft is threadedly connected with the connecting block, and the connecting block will move inside the movable groove, thereby driving the push plate to move. The push plate will push the straight tube inside the feeding seat toward the inside of the surrounding groove. When the straight tube moves to the inside of the surrounding groove, the fixed clamp will clamp the straight tube, thereby driving the straight tube to move inside the surrounding groove for detection, thereby completing the loading of the straight tube. After the detection, the straight tube moves to the inside of the surrounding groove close to the outlet. When the material seat is in the position, the first telescopic rod will drive the straight tube to move upward, and then put the straight tube into the discharge seat. At this time, the feeding motor inside the discharge seat will be in the position close to the surrounding groove inside the discharge seat, and the loading and unloading motors will drive the transmission shaft to continue to rotate. Since there are reciprocating threads on the transmission shaft, the connecting block will move toward the position close to the loading and unloading motors. At this time, the push plate will move in the opposite direction inside the feeding seat and the discharge seat, and then the straight tube inside the discharge seat can be pushed out from the surrounding groove to complete the material removal of the straight tube, achieving the effect of automatically loading and unloading the straight tube;

[0022] Fourthly: the present invention sets a screening mechanism. When the detection mechanism detects unqualified straight tubes, the feeding mechanism drives the straight tubes to move inside the surrounding groove to the position of the screening mechanism, and the fixing clamp releases the straight tubes. At this time, the third telescopic rod is activated, and the third telescopic rod pushes the pushing block out of the installation groove, and the pushing block pushes the straight tubes to move to the inside of the discharge seat. When the straight tubes are pushed to the position of the discharge port by the pushing block inside the discharge seat, the straight tubes will fall off from the inside of the discharge port, thereby completing the screening and discharge of unqualified straight tubes.
