DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present invention will be further described below with reference to the accompanying drawings through specific embodiments, but it is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention. Embodiment

[0018] A laparoscopic purulent moss removal instrument described in this embodiment, as Figure 1 and Figure 3 shown, includes a vertically arranged fixed tube 1. A flushing tube 2 and a suction tube 6 are arranged inside the fixed tube 1, which is convenient for flushing the patient's abdominal cavity and then sucking out the removed purulent moss and flushing fluid. Its structure and principle are the same as those of the existing laparoscopic aspirator. When in use, the bottom end of the flushing tube 2 is connected to the existing flushing device, and the bottom end of the suction tube 6 is connected to the existing negative pressure device; The top of the fixed tube 1 is detachably provided with a spatula 3, which is convenient for scraping the purulent moss on the abdominal wall of the patient through the spatula 3, which not only increases the contact area with the purulent moss and reduces the complexity of the operation at the same time, but also reduces the time for removing the purulent moss and improves the removal effect. The reduction of the operation time not only reduces the work pressure of medical staff but also greatly reduces the medical expenses of patients; A channel communicating with the fixed tube 1 is opened at the bottom of the spatula 3, which is convenient for sucking out the purulent moss removed by the spatula 3 through the suction tube 6, and flushing the purulent moss area through the flushing tube 2. This not only reduces the adhesion degree between the purulent moss and the tissue and makes scraping easier, but also reduces the damage of the spatula 3 to the patient's tissue; A separation block 4 for crushing the purulent moss is arranged inside the spatula 3, which is convenient for separating and crushing the purulent moss scraped by the spatula 3, and then sucking the purulent moss out through the suction tube 6, which can effectively prevent the channel from being blocked by the purulent moss with large viscosity and large volume. Embodiment

[0019] This embodiment further illustrates the technology, as Figure 5 and Figure 6 shown, a cleaning component for brushing the purulent moss is arranged on the rear side wall of the spatula 3; The cleaning component is composed of several fixing blocks 9. The fixing blocks 9 are in a conical structure as a whole, and the fixing blocks 9 are distributed in a circular pattern along the rear side wall of the spatula 3, which is convenient for improving the cleaning effect and making it possible to flexibly clean the purulent moss by combining the spatula 3 and the fixing blocks 9 according to the state of the purulent moss during cleaning, making the cleaning more thorough; The cleaning component can also be composed of several scraping strips distributed up and down. The scraping strips are in a wavy structure as a whole, and the length of the scraping strips gradually becomes shorter from both ends to the middle. Embodiment

[0020] This embodiment further illustrates the technology, as Figure 1 and Figure 2As shown, a connecting pipe 5 is vertically fixed to the bottom end of the spatula 3. The movable end of the connecting pipe 5 is in threaded fit with the top end of the fixed pipe 1, and the connecting pipe 5 is connected and communicated with the channel, which is convenient for disassembling the spatula 3 for cleaning and replacement, improving the cleanliness and avoiding infection, and at the same time reducing the use cost. Embodiment

[0021] This embodiment further illustrates the technology. As Figure 1 and Figure 5 shown, the spatula 3 is composed of a lower spoon body 3.1 and an upper spoon body 3.2. The lower spoon body 3.1 is fixed to the connecting pipe 5, and the upper spoon body 3.2 is made of an elastic material. The separating block 4 and the fixing block 9 are both arranged in the area of the upper spoon body 3.2. When removing the purulent coating, by pushing the fixed pipe 1, the upper spoon body 3.2 can be brought into contact with the tissue at the purulent coating of the patient. Then, when continuously pushing the fixed pipe 1, the upper spoon body 3.2 gradually deforms and bends inward, so as to facilitate the removal of the purulent coating. While removing the purulent coating through the upper spoon body 3.2 at the front side, the remaining purulent coating is brushed and scraped by the fixing block 9 at the rear side, making the removal more thorough. The upper spoon body 3.2 is made of silica gel material. Embodiment

[0022] This embodiment further illustrates the technology. As Figure 1 and Figure 4 shown, the separating block 4 is composed of a number of uniformly distributed cones, and the movable ends of the cones are in the same plane, which is convenient for separating and crushing the purulent coating entering the area of the spatula 3, enabling it to be quickly adsorbed and discharged, and at the same time avoiding damage to the patient's tissue caused by contact between the cones and the patient's tissue. Embodiment

[0023] This embodiment further illustrates the technology. As Figure 4 shown, both the separating block 4 and the fixing block 9 are made of silica gel material, and the length of the fixing block 9 is less than that of the separating block 4, which is convenient for adjusting its hardness by controlling the length, so as to facilitate the separation and removal of the purulent coating by the separating block 4 and the fixing block 9 respectively while reducing the damage to the patient's tissue. Embodiment

[0024] This embodiment further illustrates the technology. As Figure 2 shown, a limiting plate 7 for fixing the positions of the flushing pipe 2 and the suction pipe 6 is detachably arranged on the inner side wall of the fixed pipe 1. A sealing ring 8 is arranged on the limiting plate 7 between the fixed pipe 1 and the connecting pipe 5, and the sealing ring 8 is fixed to the top of the limiting plate 7, which is convenient for limiting the flushing pipe 2 and the suction pipe 6 to avoid displacement during use and affecting the use, improving the sealing effect between the connecting pipe 5 and the fixed pipe 1, and also facilitating the limitation of the position of the limiting plate 7 through the sealing ring 8, effectively avoiding the detachment of the limiting plate 7. The limiting plate 7 and the fixed pipe 1 can be in threaded fit or interference fit. The sealing ring 8 is attached through the connecting pipe 5 to prevent the limiting plate 7 from falling off while improving the connection firmness between the connecting pipe 5 and the fixed pipe 1; An annular groove for the insertion of the connecting pipe 5 is formed on the outer side wall of the fixed pipe 1, and an annular groove for the insertion of the fixed pipe 1 is correspondingly formed on the inner side wall of the connecting pipe 5. The sealing ring 8 is installed between the top end of the fixed pipe 1 and the bottom of the annular groove on the connecting pipe 5. Embodiment

[0025] This embodiment further illustrates the technology. As Figure 1 and Figure 2 shown, a groove is formed at the bottom of the lower spoon body 3.1. The top ends of the flushing pipe 2 and the suction pipe 6 are located in the groove, and the horizontal heights of the top ends of the flushing pipe 2 and the suction pipe 6 are lower than the horizontal height of the groove opening. This is convenient for quickly sucking out the scraped purulent moss through the suction pipe 6, and at the same time, it is also convenient to reduce the impact on the patient's internal tissues when the suction pipe 6 adsorbs. Embodiment

[0026] This embodiment further illustrates the technology. As Figure 1 shown, through grooves communicating left and right are formed on the left and right side walls on the front side of the scraping spoon 3, and the separating block 4 is located in the area of the through groove. This is convenient for the front end of the scraping spoon 3 to be in a claw-like structure to scrape off the purulent moss, and it is also convenient to quickly introduce the scraped purulent moss into the upper spoon body 3.2 through the suction pipe 6 for suction, thereby further reducing the operation time. Embodiment

[0027] This embodiment further illustrates the technology. As Figure 1 shown, the outer side wall of the top end of the fixed pipe 1 is integrally in a frustum shape, and the width of the scraping spoon 3 is equal to or less than the maximum diameter of the fixed pipe 1. This is convenient for the installation of the connecting pipe 5 and the fixed pipe 1, and at the same time, it is also convenient for the fixed pipe 1 to be inserted more smoothly, and for aesthetic reasons.

[0028] Working principle: first connect the flushing tube 2 to the flushing device, connect the suction tube 6 to the negative pressure device, and then insert the front end of the fixed tube 1 into the patient's abdominal cavity; method one, scrape the pus moss in the patient's body through the front side of the scraper 3, separate and crush the pus moss scraped into the scraper 3 through the separation block 4, and then suck it out through the suction tube 6, and flush it through the flushing tube 2 before and after scraping; method two, first brush the pus moss through the fixed block 9 on the rear side of the scraper 3, and then scrape the brushed pus moss into the scraper 3 through the front side of the scraper 3 and suck it out through the suction tube 6 Method three, push the fixed tube 1 to make the upper spoon body 3.2 contact with the tissue at the patient's pus moss, and then continue to push the fixed tube 1 to make the upper spoon body 3.2 gradually deform and bend inward, and then move laterally to remove the pus moss. While the upper spoon body 3.2 is used to remove the pus moss on the front side, the fixed block 9 on the rear side is used to brush and scrape the remaining pus moss. The pus moss scraped into the upper spoon body 3.2 is separated and crushed by the separation block 4, and sucked out by the suction tube 6, and also rinsed by the flushing tube 2 at the front and back.
