Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a gastroenteroscopic polyp removal collector and a control component. Background Art

[0002] Polyps refer to abnormal tissues protruding from the mucosal surface. Before the pathological nature is determined, they are generally called polyps. Generally speaking, polyps are formed by the growth and aggregation of cells originating from the mucosa. Polyps growing in the stomach are called gastric polyps. They are common clinical diseases. Most gastric polyps are found accidentally during upper gastrointestinal endoscopy. Most polyps are benign lesions and will not endanger life. Only a part of polyps have a tendency to become cancerous and need active treatment. In addition, samples of removed polyps need to be kept for testing to determine the pathological nature of the polyps. Among the existing methods for removing and collecting polyps, high-frequency electrocoagulation resection is the most widely used. In the process of removing pedunculated polyps or narrow-pedunculated polyps, the thermal effect generated by high-frequency current is used to promote tissue coagulation and necrosis to achieve the purpose of removing polyps. However, when heating and coagulating the pedicles, it is often difficult to remove the pedicles because the polyps are soft and easy to collapse, resulting in close contact between the polyps and the electric wires, damaging the polyp structure. In addition, since polyps grow in all directions in the gastrointestinal tract, there is a problem of difficulty in positioning during cutting. In order to avoid this situation, the patient's body position is usually changed, which is cumbersome and inconvenient to operate, and the quality of the polyps after removal cannot be guaranteed. The polyp removal equipment in the prior art usually lacks sufficient flexibility and accuracy, especially when the removal position is inconvenient to contact or the polyps are irregular in shape. In addition, the existing equipment may have a risk of contamination during the collection and storage process after polyp removal, affecting subsequent pathological analysis. To this end, the present invention provides a gastroenteroscopic polyp removal collector and a control component to solve the problems existing in the above-mentioned prior art. Summary of the invention

[0003] In order to solve the above technical problems, the present invention designs a colonoscopic polyp removal collector and control component, designs a retractable clamp cap, and arranges a suction cup inside the clamp cap. The polyp is positioned by the clamp cap, and the suction cup is used to fix it, so that the cutting blade is better positioned at the base of the polyp, and a sliding cutting blade is arranged at the bottom, and the cutting blade is driven to slide by a rope, so as to adapt to the positioning and cutting of polyps in various directions in the gastrointestinal tract; at the same time, a spiral conveyor is arranged in the center, and after the polyp cutting is completed, the polyp is put into the conveyor through the clamp cap, and the polyp is transported to the storage; In order to achieve the above technical effects, the present invention is implemented by the following technical solutions: a colonoscopic polyp removal collector and control assembly, including: a handle, a pipeline, a clamping mechanism, a cutting mechanism, and a conveying mechanism; A pipe is arranged at the front end of the handle; a clamping mechanism is arranged at the top of the pipe, a conveying mechanism is arranged in the middle, and a cutting mechanism is arranged at the bottom; The cutting mechanism comprises a cutting blade, a double-headed motor, a slider, a rope, a cutting rod, and a sliding motor; a semicircular ring slide groove is arranged at the bottom of the pipe, and a slider is arranged in the slide groove; the slider is fixedly connected to the cutting rod, and holes are respectively provided at the front and rear ends of the slider to connect the rope; the front end of the cutting rod is fixedly connected to the double-headed motor; the two output shafts of the double-headed motor are respectively connected to the cutting blade; the rope is arranged in a ring along the semicircular ring slide groove, and a sliding motor is arranged at one end; Furthermore, the front end hole of the slider is movably connected to the rope, and the rear end hole is fixedly connected to the rope; Furthermore, the handle includes a negative pressure device, a polyp storage device, a filter, a battery pack, and a console; the negative pressure device is arranged at the top of the handle and connected to the clamping mechanism; the polyp storage device is arranged at the lower end of the conveying mechanism, and a filter is arranged inside; the battery pack is arranged below the negative pressure device, and a console is arranged on the side; Furthermore, the clamping mechanism includes a clamping pipe, a clamping cap, a suction cup, a negative pressure pipe, a telescopic mechanism, a telescopic pipe, and a lifting mechanism; the lower end of the clamping cap is meshed, and a hole is provided on the top to connect the suction cup; the suction cup is fixedly connected to the negative pressure pipe; the negative pressure pipe sleeve is arranged in the telescopic pipe and connected to the negative pressure device, and a telescopic mechanism is provided at the place where the negative pressure pipe is connected to the telescopic pipe; the telescopic pipe is connected to the clamping pipe through the lifting mechanism; Furthermore, the telescopic device includes a screw rod, a telescopic motor, and a connecting seat; the connecting seat is provided on both the negative pressure tube and the telescopic pipe; the screw rod is connected to the connecting seat through an internal thread; and the telescopic motor is provided on the top of the screw rod; Furthermore, the lifting mechanism includes a lifting motor, a cam, and a telescopic connecting rod; the telescopic motor is arranged at the top of the clamping pipe and connected to the cam; a telescopic connecting rod is arranged at the bottom of the clamping pipe to connect the telescopic pipe; Furthermore, a sliding groove is provided on the outer edge of the cam and is movably connected to the telescopic pipe; Furthermore, the conveying mechanism includes a conveying motor, a conveyor, a conveying pipeline, and a conveying shell; the conveying shell is arranged above the cutting mechanism slideway, and connecting shafts are arranged at both ends to connect the conveying pipeline; the conveyor is arranged in the conveying pipeline; the conveyor is arranged at the front end of the conveyor; Furthermore, square holes are arranged above the front ends of the delivery pipe and the delivery shell for the polyps to enter; and a square hole is arranged at the bottom of the end of the delivery pipe for the polyps to enter the polyp storage.

[0009] In this embodiment, when the device is in use, the pipeline 1 is inserted into the patient's stomach along with the gastroenteroscopy, and the positioning is performed through gastroscopy observation. The clamping cap 10 is adjusted through the telescopic mechanism and the lifting mechanism, and the polyp is fixed by the suction cup 11. After the position and angle of the cutting blade 5 are fixed, the cutting blade 5 is pressed against the base of the polyp, and the double-headed motor is started to rotate the two shafts in the opposite direction, so that the two cutting blades 5 clamp the polyp. At this time, the high-frequency electrocoagulation device is started to make the polyp tissue coagulate and necrotize, and gradually separate from the surrounding normal tissue. After the polyp is removed, the suction cup 11 sucks the polyp, and the clamping cap 10 is aligned with the square holes on the conveying pipeline 7 and the conveying shell 29 through the lifting mechanism and the telescopic mechanism. At this time, the conveying motor 14 is started to drive the conveyor 13 to rotate, the negative pressure device 2 is closed, and the polyp is placed in the conveyor 13, and the polyp is transported to the end of the conveying pipeline 7 through the conveyor 13, and falls into the polyp storage 3 through the hole at the bottom of the end of the conveying pipeline 7, and the waste liquid on the polyp is filtered out by the filter sheet 16; In this embodiment, the working principle of the cutting mechanism is: the sliding motor 27 is rotated to drive the telescopic rotation, and is fixedly connected to the rope 26 through the rear end hole, so that the telescopic rotation drives the slider 8 to slide along the semicircular ring groove, thereby adjusting the position and angle of the cutting blade 5; In this embodiment, the retractable clamp cap 10 and suction cup 11 of the clamping mechanism are designed so that the operator can make fine adjustments according to the size and position of the polyp to achieve precise positioning and fixation. This design reduces unnecessary touching of the polyp during surgery and reduces the risk of injury. The design of the mesh clamp cap 10 increases the contact area with the polyp, improves the adsorption effect, and adapts to polyps of different shapes, enhancing the versatility and applicability of the clamping mechanism. The use of the negative pressure device 2 not only enhances the adsorption force of the suction cup 11, but also provides a stable fixation method, so that even if the polyp is accidentally moved during the removal process, it can be firmly held in place; In this embodiment, the design of the sliding cutting blade 5 allows the cutting mechanism to be adjusted in multiple directions to accommodate polyps of different positions and shapes, which increases the flexibility and scope of application of the operation. The design of the double-headed motor allows the two cutting blades 5 to operate independently or synchronously, providing a more refined control capability and facilitating accurate cutting. Through the cooperation of the rope 26 and the sliding motor 27, the cutting mechanism can be automatically adjusted to the optimal position, reducing the need for manual adjustment and improving the efficiency of the operation. In this embodiment, the design of the spiral conveyor 13 ensures that the cut polyps can be quickly and safely transferred from the surgical area to the storage device, thereby improving the continuity of the surgical process. The square hole design of the delivery pipe 7 and the delivery housing 29 simplifies the entry and delivery process of the polyps, reduces the operational obstacles and time consumption during the operation, and the reverse function of the delivery motor 14 can quickly clear the delivery pipe 7 when it is congested, thereby ensuring the continuity of the operation and reducing the risk of equipment failure. In summary, the present invention can accurately locate and fix polyps through the retractable clamp cap 10 and the built-in suction cup 11 to prevent them from moving or being damaged during the removal process. The mesh clamp cap 10 design helps to better adapt to polyps of different shapes, increase the contact area, and improve the adsorption effect. The use of the negative pressure device 2 can enhance the adsorption capacity of the suction cup 11 on the polyps, ensuring the stability of the polyps during the removal process. The design of the sliding cutting blade 5 allows the cutting blade 5 to slide in different directions to adapt to polyps growing in different directions in the gastrointestinal tract, thereby improving the flexibility and accuracy of cutting. The use of the double-headed motor can simultaneously control two cutting blades 5 to achieve more accurate cutting action. At the same time, the design of arranging a spiral conveyor 13 in the pipeline can effectively convey the cut polyps to the storage device, avoiding secondary damage to the polyps. The square hole design of the conveying pipeline 7 and the conveying shell 29 facilitates the smooth entry and transmission of the polyps and reduces obstacles during operation. The setting of the conveying motor 14 can control the speed and direction of the conveyor 13 to ensure the safety of the polyps. At the same time, if the pipeline is congested, the conveying motor 14 can be reversed to clear the pipeline.
