Description

Technical Field

[0001] This utility model relates to the field of endoscopic traction technology, specifically to an auxiliary traction component for digestive endoscopy. Background Technology

[0002] Gastrointestinal endoscopy is a set of equipment used to diagnose and treat digestive system diseases. It involves directly acquiring images of the digestive tract or obtaining ultrasound or X-ray images of the digestive tract and organs via devices equipped with ultrasound and X-ray equipment. Endoscopy is generally used in conjunction with an auxiliary traction device. This traction technique typically uses a special transparent plastic rope called a "traction line," which is inserted into the digestive tract through the biopsy channel of the endoscope and fixed to the lesion under the mucosa. The doctor can then control the position and direction of the lesion by pulling on the traction line for better resection.

[0003] Existing traction devices generally only have a clamping function. For example, in an existing published patent: "Auxiliary Traction Device for Digestive Endoscopy (Publication No.: CN214434436U)" "includes a flexible tube, a guide wire movably connected to the inner wall of the flexible tube, a fixed base fixedly connected to one end of the guide wire, a connecting rod movably connected to the inner wall of the fixed base, a clamping block movably connected to one end of the connecting rod, a forceps head fixedly connected to one end of the flexible tube, and a conical sleeve fixedly connected to the other end of the flexible tube. This auxiliary traction device for digestive endoscopy allows the flexible tube to be inserted into the patient's body through an auxiliary gastroscope. When the forceps head is in the designated position, one hand is placed on the surface of the fixed block, and the other hand pulls the pull ring. The pull ring moves the fixed rod, which moves the guide wire, which pulls the fixed base, which moves the connecting rod, causing the clamping block to open and clamp the foreign object to be clamped. Releasing the pull ring compresses the spring, pushing the fixed rod to move, causing the clamping block to close and clamp the foreign object, thus facilitating the clamping of the foreign object." It can only clamp foreign objects, but pus usually appears at the lesion site. At this time, the traction device cannot simultaneously aspirate the pus, which reduces the functionality and practicality of the traction device. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are only some embodiments, not all embodiments. Based on the embodiments described, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0023] Example 1:

[0024] Please see Figure 1-4An auxiliary traction assembly for digestive endoscopy includes a fixation cylinder 1, a catheter 2 fixedly mounted at the front end of the fixation cylinder 1, a pull rod 3 slidably mounted on the inner wall of the fixation cylinder 1, a pressure plate 4 slidably mounted on the inner wall of the fixation cylinder 1, a first spring 5 wound around the outer side of the pull rod 3, a guide wire 6 mounted on the front surface of the pressure plate 4, a sliding plate 7 slidably mounted on the inner wall of the front end of the catheter 2, an installation chamber mounted at the lower part of the catheter 2, a fixing rod 8 fixedly mounted on the inner wall of the installation chamber, a second spring 10 wound around the outer side of the fixing rod 8, a slider 9 slidably mounted on the outer side of the fixing rod 8, a pull plate 11 fixedly mounted at the lower part of the slider 9, a suction tube 12 mounted on the surface of the pull plate 11, a connecting valve port 13 mounted at the rear end of the suction tube 12, a suction port 14 mounted at the front end of the suction tube 12, and a handle 17 fixedly mounted on the surface of the fixation cylinder 1.

[0025] Specifically, such as Figure 2 and Figure 3 As shown, the initial state of the suction port is inside the catheter 2. When the doctor operates, he can hold the handle 17 with one hand and pull the lever 3 with the other hand. The lever 3 will drive the pressure plate 4 to move. The pressure plate 4 will squeeze the first spring 5. The pressure plate 4 will drive the guide wire 6 to move. The guide wire 6 will drive the slide plate 7 to move. After releasing, the first spring 5 will drive the pressure plate 4 back. As the guide wire 6 and slide plate 7 are retracted, the clamp 20 in front of the control catheter 2 is clamped. At the same time, the connecting valve port 13 can be connected to an external suction pump. Then, the suction port 14 can generate suction through the suction tube 12.

[0026] Preferably, the two ends of the second spring 10 are connected to the front surface of the slider 9 and the inner wall of the mounting chamber, respectively. The outer side of the slider 9 is slidably connected to the inner wall of the mounting chamber. The liquid extraction tube 12 is movably installed inside the conduit 2. The lower surface of the conduit 2 and the surface of the slide plate 7 are provided with mounting ports, and the liquid extraction tube 12 passes through the mounting ports.

[0027] Specifically, when not in use, the suction port will be inside the catheter 2 and will not obstruct the use of the traction structure.

[0028] Preferably, the two ends of the first spring 5 are connected to the inner walls of the pressure plate 4 and the fixed cylinder 1, respectively, and the front end of the guide wire 6 is connected to the rear surface of the slide plate 7.

[0029] Working principle: During testing, when pus is found in the patient's body, the suction pump can be connected to the connecting valve port 13. Then, the push plate can be moved backward, which will drive the suction tube 12 forward, pushing the suction port towards the pus. The slider 9 will move forward along the fixed rod 8, squeezing the second spring 10 to generate pressure. After the suction is completed, the push plate is released, and the second spring 10 will quickly move the sliding plate 7 backward. The push plate will then drive the suction tube 12 backward, thereby bringing the suction port into the catheter 2. The position of the suction port can be easily adjusted, and the pus can be accurately suctioned. This improves the practicality and functionality of the traction device and makes it easier for medical staff to use.

[0030] Example 2:

[0031] Please see Figure 1-4 Preferably, a fixed seat is installed on the front of the slide plate 7, a connecting rod 15 is movably installed on the inner wall of the fixed seat, and a connecting shaft 16 is fixedly installed on the inner wall of the front end of the guide tube 2, with the connecting rod 15 and the connecting shaft 16 being rotatably connected.

[0032] Specifically, the backward movement of the slide plate 7 pulls the connecting rod 15 to retract, thereby bringing the clamping plates 20 at the front end of the connecting rod 15 closer together, which can clamp foreign objects.

[0033] Preferably, the front end of the connecting rod 15 is fixedly provided with an installation groove 18, the inner wall of the installation groove 18 is provided with an installation block 19, and the front part of the installation block 19 is fixedly provided with a clamping plate 20.

[0034] Specifically, the mounting block 19 can be installed into the mounting slot 18, allowing the clamping plate 20 to be disassembled.

[0035] Preferably, fixing grooves 21 are fixedly installed on both sides of the mounting block 19, a third spring 22 is installed inside the fixing groove 21, a connecting plate is connected to the outer end of the third spring 22, a positioning bead 23 is installed on the outer side of the connecting plate, the connecting plate is slidably connected to the inner wall of the fixing groove 21, and a positioning circular groove 24 corresponding to the positioning bead 23 is opened on the inner wall of the mounting groove 18.

[0036] Specifically, after the mounting block 19 is installed into the fixing groove 21, the positioning bead 23 has low friction and can be easily installed into the mounting groove 18. Then, the connecting plate slides and squeezes the third spring 22. After the mounting block 19 is installed into the fixing groove 21, the positioning bead 23 moves into the positioning groove.

[0037] Working principle: As described in Example 1, the pull rod 3 will drive the pressure plate 4 to move, the pressure plate 4 will squeeze the first spring 5, the pressure plate 4 will drive the guide wire 6 to move, the guide wire 6 will drive the slide plate 7 to move, and after being released, the first spring 5 will drive the pressure plate 4 back. As the guide wire 6 and the slide plate 7 are retracted, the clamp 20 in front of the control catheter 2 is clamped, which can remove foreign objects. With the cooperation of the positioning post, positioning hole and the third spring 22, the clamp 20 can be easily installed and removed, and the doctor can easily replace the clamp 20 on the traction device quickly.
