Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a novel endoscopic positioning auxiliary device for digestive tract lesions. Background Art

[0002] Laparoscopic minimally invasive treatment technology is widely used in clinical practice. It has replaced traditional laparotomy in the treatment of many diseases, achieving the ideal goal of good efficacy, rapid recovery, and minimally invasive cure. However, laparoscopic technology, especially laparoscopic surgery, has a major defect - loss of tactile sensation; the surgeon cannot check by hand to determine the location, range, and relationship with surrounding tissues of the lesion as in open surgery. Inaccurate preoperative positioning may mislead the surgeon. Repeated exploration of the lesion during surgery will not only prolong the operation time, but also increase the chances of tumor spread, implantation metastasis, bleeding, anastomotic leakage, and infection. In severe cases, it may even lead to mis-resection of the lesion. Therefore, accurate positioning of gastrointestinal lesions is very important for the selection of surgical methods, incisions, and body positions.

[0003] Currently, for the positioning of intestinal malignant tumors before resection during surgery, it is necessary to mark the lesion location by injecting nanocarbon during colonoscopy and find the colored marked area outside the intestine under laparoscopy. This method has the following main shortcomings: the cost of nanocarbon is relatively high, which increases the financial burden on patients; there may be problems such as inaccurate positioning or difficulty in finding the colored area.

[0031] For further information, see Figure 5The connecting part 2 includes a connecting shell 4, and an upper card slot 5 and a lower card slot 10 are provided inside the connecting shell 4. The upper card slot 5 is used to connect the positioning mechanism 3, and the lower card slot 10 is used to connect the endoscope tube 1. The positioning mechanism 3 is quickly connected to the endoscope tube 1 through a connecting part 2, which is convenient for simplifying the operation process and improving the installation efficiency. It should be noted that a through hole is provided on the connecting shell 4, and this hole corresponds to the endoscope operation hole, which is convenient for suction and inflation of waste liquid during the insertion of the endoscope tube 1, and is convenient for user operation. Suction of waste liquid and inflation are operations of the prior art and are conventional structures, which will not be described in detail here.

[0032] For further information, please refer to Figure 5 The upper card slot 5 is symmetrically provided with inner slots 6, and the two inner slots 6 are symmetrically fixedly connected with spring sheets 7, which are elastic. The ends of the two spring sheets 7 close to each other are fixedly connected with a limiting plate 8, and the ends of the two limiting plates 8 close to each other are fixedly connected with a clamping block 9. Under the elastic action of the spring sheets 7, it is convenient to drive the clamping block 9 to move inside the inner slot 6, so as to facilitate installation and disassembly. In addition, the lower card slot 10 is symmetrically provided with connecting slots 11, and the two connecting slots 11 are fixedly connected with springs 12. The ends of the two springs 12 close to each other are fixedly connected with a soft pad 13, and the ends of the two soft pads 13 close to each other are fixedly connected with an anti-slip block 14. Through the action of the soft pad 13 and the anti-slip block 14, the endoscope pipe 1 can be prevented from slipping, so as to prevent the connection part 2 from being separated from the endoscope pipe 1 during work, thereby making the connection of the connection part 2 more stably connected.

[0033] Embodiment 2: Figure 4 , Figure 7 , Figure 8 and Fig. 9As shown, this is a further description of the first embodiment. In this embodiment, the positioning mechanism 3 includes a motor 16, which is a brushless motor powered by a built-in battery. The motor 16 is fixedly installed inside the housing 15, and the output end of the motor 16 is fixedly connected to a rotating shaft 17. The outside of the rotating shaft 17 is fixedly connected to a turntable 18, and the end of the rotating shaft 17 away from the motor 16 is rotatably connected to the inner wall of the housing 15. Specifically, the outside of the rotating shaft 17 is symmetrically fixedly connected to large gears 30, and the two large gears 30 are respectively located above and below the turntable 18, so as to synchronously drive multiple components to operate, thereby playing multiple roles. The outside of one of the large gears 30 is meshedly connected to an upper gear 19, and the upper gear 19 is a long gear. The two upper gears 19 are both rotatably connected to the turntable 18. The two upper gears 19 are connected to the turntable 18. The outside of the wheel 19 is meshed with an upper rack 20, which is staggered with the large gear 30 and does not affect each other. The outside of the two upper racks 20 is slidably connected with a connecting plate 21, and the two connecting plates 21 are fixedly connected to the inner wall of the shell 15. The outside of the two upper racks 20 is fixedly connected with a support rod 22, and the top of the two support rods 22 is fixedly connected with an elastic head 23. The elastic head 23 makes the support rod 22 round, which can prevent damage to the patient's intestines and reduce the risk of perforation. The two support rods 22 can penetrate and extend to the outside of the shell 15, and the upper gear 19 is driven to rotate by the large gear 30, and the upper gear 19 drives the upper rack 20 to move, thereby controlling the entry and exit of the support rod 22, which is convenient for fixing the lesion, thereby preventing the positioning position from being changed due to intestinal peristalsis.

[0034] Furthermore, through grooves 33 are symmetrically provided on the housing 15, and sealing diaphragms 34 are fixedly connected inside the two through grooves 33. The sealing diaphragm 34 is inside the housing 15, which can prevent body fluids from entering the interior of the housing 15 after the block 9 is detached. The two through grooves 33 correspond to the block 9. The interior of the housing 15 is fixedly connected to a limiting shell 24, and the external thread of the rotating shaft 17 is connected to a slider 25. The slider 25 is slidably connected to the limiting shell 24. The limiting shell 24 is used to limit the slider 25. The slider 25 is a rectangular parallelepiped. The internal shape of the limiting shell 24 fits the shape of the slider 25. The top is symmetrically fixedly connected with a positioning rod 26, and the top of the positioning rod 26 and the elastic head 23 are fixedly connected with an electromagnetic suction 39, which is powered by a power controller 38. The internal magnetic suction of the electromagnetic suction 39 is connected to a titanium clip 40, and the outside of the titanium clip 40 is fixedly connected with a magnetic suction block 41. The electromagnetic suction 39 controls the adsorption and release of the titanium clip 40 through the magnetic suction block 41. Both positioning rods 26 can penetrate and extend to the top of the outer shell 15. The shape and material of the top of the positioning rod 26 are consistent with the support rod 22. The lesion is positioned in multiple directions through the titanium clip 40 to make its position more accurate and firm.

[0035] For further information, see Figure 2 and Figure 8, the outer part of another large gear 30 is symmetrically meshed with a lower gear 27, the lower gear 27 is consistent with the upper gear 19 in shape and material, the two lower gears 27 are rotatably connected to the turntable 18, the outer parts of the two lower gears 27 are meshed with lower racks 29, the outer parts of the two lower racks 29 are slidably connected with fixed blocks 28, the two fixed blocks 28 are fixedly connected to the housing 15, the bottoms of the two lower racks 29 are fixedly connected with top plates 31, and the ends of the two top plates 31 away from each other are fixedly connected with top blocks 32. When the doctor finds the lesion, through The motor 16 inside the housing 15 drives the rotating shaft 17 to rotate, thereby driving the two large gears 30 to rotate, and then synchronously drives the upper gear 19 and the lower gear 27 to rotate, and cooperates with the slider 25 to synchronously drive the support rod 22 and the positioning rod 26 to extend into the lesion. At the same time, the lower rack 29 drives the top plate 31 and the top block 32 to squeeze the block 9 inside the two sealing membranes 34, so as to facilitate the positioning mechanism 3 to be separated from the endoscope tube 1. The positioning mechanism 3 can be firmly fixed to the tumor site and is not easily washed away by intestinal peristalsis or other liquid objects. At the same time, the sensor 36 and the signal transmitter 37 send signals to the outside, and the doctor determines the specific position of the signal transmitter 37 through an external monitor. The closer to the position, the stronger the signal. Marking outside the patient's body is convenient for determining the insertion position and angle of the laparoscope before inserting the laparoscope. At the same time, when the laparoscope is inserted, the electromagnetic suction cup inside the laparoscope is used to adsorb the magnetic suction block 41 on the surface of the titanium clip 40, so as to more quickly and accurately determine the position of the lesion, thereby facilitating the improvement of the accuracy of positioning.

[0036] In summary, when using this device:

[0037] First, after disinfection, insert the lower card slot 10 at the bottom of the connecting shell 4 into the top of the endoscope pipe 1. With the cooperation of the anti-sliding block 14, the cushion 13 and the spring 12, the connection can be made more stable. Then, insert the outer shell 15 into the upper card slot 5 above the connecting shell 4. The card block 9 automatically inserts into the through slot 33 to quickly complete the installation.

[0038] Secondly, with the assistance of the camera 35 and the endoscope tube 1, the lesion position is found, and then the motor 16 is controlled to rotate by the controller. The rotation of the motor 16 drives the rotating shaft 17 to rotate, and then drives the slider 25 to move along the limit shell 24, thereby driving the positioning rod 26 to extend into the lesion, and then the electromagnetic suction 39 is released by the power controller 38 to clamp the lesion. At the same time, the positioning rod 26 cooperates with the titanium clip 40 to fix the lesion. At the same time, the two large gears 30 synchronously drive the two upper gears 19 and the lower gear 27 to rotate, and then synchronously drive the two upper racks 20 and the lower rack 29 to slide, and then respectively drive the support rod 22 to fix the lesion outward, and at the same time drive the top block 32 to squeeze the sealing diaphragm 34 and the block 9, so that the block 9 is separated from the shell 15, thereby separating the endoscope tube 1 from the positioning mechanism 3;

[0039] Finally, the sensor 36 and the signal transmitter 37 send signals to the outside, and the doctor senses the specific position of the positioning mechanism 3 through the monitor. The closer to the lesion location, the stronger the signal is. Marking is performed outside the patient's body to facilitate determining the laparoscope insertion position and angle before inserting the laparoscope. After the position is determined, the motor 16 is controlled by the controller to retract it, and the outer shell 15 can be discharged from the body through the intestine.
