Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to a tumor effusion drainage device. Background Technique

[0002] In the late stage of patients with malignant tumors, pleural, peritoneal and pericardial metastases often occur, resulting in the occurrence of malignant pleural effusion, malignant peritoneal effusion and malignant pericardial effusion. The treatment is closed drainage and local injection of anti-tumor drugs to control the production of effusion. During the effusion drainage process for patients, first, a suitable body position is selected according to the effusion site and the patient's comfort. Subsequently, the puncture site is disinfected and infiltration anesthesia is performed using a local anesthetic drug (such as 2% lidocaine). During the puncture process, the skin at the puncture point is fixed with the left hand, and the puncture needle is slowly inserted with the right hand. When there is effusion flowing out of the syringe, insert the needle another 0.3 - 0.5 cm to ensure that the port of the puncture needle enters the patient's body. A catheter is left in the patient's body (usually 10 - 15 cm) and connected to a drainage tube. Subsequently, the drainage tube is opened to allow the effusion to flow out naturally. During the drainage process, the patient's vital signs and drainage conditions should be closely observed, and the color, volume and properties of the drained fluid should be recorded;

[0003] During the drainage process, since tumor effusion may contain blood, pus, protein, cellulose, tumor cells and other impurities, and the tumor tissue is composed of a large number of tumor cells, these cells may shed and form fragments during growth, and the surface of these tumor tissue fragments is often adhered to by high-viscosity tumor effusion. Therefore, during the drainage process, the inside of the drainage tube is often blocked by tumor tissue. On the one hand, the effusion in the body may not be discharged smoothly, resulting in the accumulation of fluid in the body. On the other hand, it increases the probability of reflux. For this reason, we propose a tumor effusion drainage device. Summary of the Invention

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-10, the present invention provides a technical solution: a tumor effusion drainage device, including a drainage bottle 1 located outside the patient. The inlet and outlet of the drainage bottle 1 are both fixedly connected with a drainage tube 2. The inner hole of the drainage tube 2 in the present invention is arranged in a cross structure. By arranging it in a cross structure, it can effectively play an anti-bending effect. In the actual application process, the drainage tube 2 will inevitably be bent due to external environmental factors. However, the inner hole of the drainage tube 2 in the present invention can effectively play an anti-bending role due to its cross structure setting to avoid the bending condition of the drainage tube 2. And one end of one of the drainage tubes 2 is communicated with a drainage instrument 3. The drainage bottle 1 includes a bottle body 101 and a cover body 102 threadedly connected to the bottle body 101. A filter sleeve 4 is threadedly connected inside the cover body 102. The filter sleeve 4 is located inside the bottle body 101, and a connecting sleeve 5 is fixedly installed at the bottom of the filter sleeve 4. A power unit 6 is fixedly installed inside the connecting sleeve 5. It should be noted that the power unit 6 is composed of a servo motor and a gear set. A crushing unit 7 for crushing tumor tissue fragments is arranged inside the filter sleeve 4, and the crushing unit 7 is connected to the power unit 6 through a connecting part 8; the crushing unit 7 includes a mounting plate frame one 71 and a mounting plate frame two 72 located above the mounting plate frame one 71. A plurality of crushing blades 73 are rotatably installed on the mounting plate frame one 71, and a plurality of cutting blades 74 are rotatably installed on the mounting plate frame two 72; in the normal state, the crushing blades 73 and the cutting blades 74 are arranged in an inclined state;

[0031] As a further limitation in the present invention, the connecting part 8 includes a limiting sleeve 81 rotatably connected to the inner wall of the connecting sleeve 5. The limiting sleeve 81 is fixedly connected to the power unit 6, and a connecting shaft body 82 slidably connected to its inner wall is installed inside the limiting sleeve 81. The end of the connecting shaft body 82 penetrates through the inner wall of the limiting sleeve 81 and is fixedly connected to the mounting plate frame one 71. The power unit 6 drives the mounting plate frame one 71 to rotate through the limiting sleeve 81 to drive the connecting shaft body 82. And a magnetic panel 83 is fixedly installed at one end of the connecting shaft body 82 located inside the limiting sleeve 81. A plastic spring 84 is connected between the magnetic panel 83 and the inner wall of the limiting sleeve 81. An electric magnetic group 85 is fixedly installed at the bottom of the limiting sleeve 81, and the electric magnetic group 85 generates a repulsive force on the magnetic panel 83 when energized; A fixed sleeve 14 is also fixedly installed on the mounting plate frame one 71, and a limiting shaft body 15 slidably connected to its inner wall is installed inside the fixed sleeve 14. The end of the limiting shaft body 15 is fixedly connected to the bottom of the mounting plate frame two 72. A return spring 151 is connected between one end of the limiting shaft body 15 located inside the fixed sleeve 14 and the bottom of the fixed sleeve 14;

[0032] Combined with the attached Figures 1-4As shown, during actual use, the drainage fluid enters the drainage bottle 1 through the drainage tube 2, and the drainage fluid entering the drainage bottle 1 will pass through the filter sleeve 4. The filter holes on the filter sleeve 4 will block substances such as tumor tissue fragments in the effusion that are likely to block the drainage tube 2, causing the blockage to remain in the filter sleeve 4. During this process, the power unit 6 drives the connecting shaft body 82 to rotate through the limit sleeve 81. During the rotation of the connecting shaft body 82, its end will drive the mounting disc frame one 71 to rotate. During the rotation of the mounting disc frame one 71, the fixed sleeve 14 on the mounting disc frame one 71 will drive the mounting disc frame two 72 to rotate through the limit shaft body 15. At this time, the crushing blades 73 and cutting blades 74 on the mounting disc frame one 71 and the mounting disc frame two 72 will crush the blockage to reduce the size of the massive tissue fragments and prevent the massive tissue fragments from being too large to block the drainage tube 2. The massive tissue fragments that are still larger than the size of the filter holes on the filter sleeve 4 after being chopped will fall to the bottom of the filter sleeve 4. To facilitate the contact between the massive tissue fragments and the crushing blades 73 and the cutting blades 74, the tops of the mounting disc frame one 71 and the mounting disc frame two 72 in the present invention are both inclined.

[0033] Furthermore, the present invention can effectively process massive tissue fragments with larger sizes using the crushing blades 73 and the cutting blades 74. By crushing the massive tissue fragments, the size of the massive tissue fragments can be effectively reduced, facilitating the flow of the massive tissue fragments in the drainage tube 2. At the same time, under the action of the electromagnetic component and the plastic spring 84, the positions of the crushing blades 73 and the cutting blades 74 can be effectively adjusted. When there are more massive tissue fragments in the filter sleeve 4, the positions of the crushing blades 73 and the cutting blades 74 can be adjusted to effectively crush the massive tissue fragments.

[0034] During the actual processing, when using the crushing blade 73 and the cutting blade 74 to crush the blocky tissue fragments, due to the characteristics of the blades, some blocky tissue fragments often fail to be completely crushed. Some larger-sized blocky tissue fragments are likely to accumulate in the filter sleeve 4. As the drainage time increases, more blocky tissue fragments accumulate in the filter sleeve 4, resulting in less effusion flowing out, which affects the drainage rate of the effusion. For this, the present invention makes the following design: At the output ends of the crushing blade 73 and the cutting blade 74, annular disc frames 75 are fixedly installed, and force-bearing rod frames 76 are fixedly installed on the annular disc frames 75. Inside the mounting disc frame one 71 and the mounting disc frame two 72, a plurality of guiding shaft bodies 9 are fixedly installed, and inside the mounting disc frame one 71 and the mounting disc frame two 72, acting disc frames 10 slidably connected to the guiding shaft bodies 9 are provided. Constant force springs 11 are sleeved on the guiding shaft bodies 9, and the constant force springs 11 are in contact with the acting disc frames 10. A force-applying shaft body 16 is fixedly installed on the acting disc frame 10. The force-bearing rod frame 76 is located on the movement trajectory of the force-applying shaft body 16, and torsion springs 77 are connected between the annular disc frame 75 and the inner walls of the mounting disc frame one 71 and the mounting disc frame two 72. Referring to the attached Figure 5 and the attached Figure 9 As shown, when the acting disc frame 10 moves upward on the guiding shaft body 9, the force-applying shaft body 16 on the acting disc frame 10 will exert a force on the force-bearing rod frame 76 on the movement trajectory. Then, the force-bearing rod frame 76 can drive the crushing blade 73 and the cutting blade 74 to rotate through the annular disc frame 75 under the action of the force, and the torsion spring 77 is in a deformed state;

[0035] Referring to the attached Figure 4 、the attached Figure 5 、the attached Figure 9 and the attached Figure 10 As shown, a plurality of annular sleeves 12 are fixedly installed at the bottom of the mounting disc frame one 71 and the top of the mounting disc frame two 72. A plurality of transmission shaft bodies 121 rotatably connected to the acting disc frame 10 are installed on the acting disc frame 10, and the transmission shaft bodies 121 correspond to the annular sleeves 12 one by one. The transmission shaft bodies 121 penetrate through the annular sleeves 12. Telescopic shaft bodies 122 are installed on the outer walls of the transmission shaft bodies 121, and a plurality of adjusting groove bodies 13 are provided on the inner walls of the annular sleeves 12. The telescopic shaft bodies 122 are limited to slide in the adjusting groove bodies 13. The ends of the telescopic shaft bodies 122 are spherical. As a further limitation in the present invention, each adjusting groove body 13 includes a vertical groove body 131, an arc groove body 132, and a V-shaped clamping groove body 133. The vertical groove body 131 communicates with the V-shaped clamping groove bodies 133 in the adjacent adjusting groove bodies 13. A guiding panel 134 is fixedly installed at the intersection of the vertical groove body 131 and the arc groove body 132. The guiding panel 134 has an inclined surface on one side located in the vertical groove body 131 and a right-angled surface on one side located in the arc groove body 132. Referring to the attached Figure 8As shown, the lowest point of the V-shaped clamping groove body 133 is the clamping part; in the initial state, that is, when the acting disc frame 10 does not move upward, at this time the acting disc frame 10 is at the lowest point, and the telescopic shaft body 122 is located at the lowest point of the vertical groove body 131;

[0036] Specifically, in combination with the attached Figure 4 and the attached Figure 6 As shown, during the specific use process, gradually reduce the power supply of the electromagnetic component and finally stop power supply. It should be noted that the electromagnetic component is in the power-on state in the initial state. When the electromagnetic component stops power supply, under the action of the plastic spring 84, the mounting disc frame one 71 will drop to the bottom of the filter sleeve 4. Then, when the power supply of the electromagnetic component decreases, the magnetic panel 83 will drop under the action of the plastic spring 84, and the mounting disc frame one 71 at the end of the connecting shaft body 82 and the crushing blade 73 thereon will move downward synchronously with it, that is, the mounting disc frame two 72 and the cutting blade 74 thereon will move downward under the action of the fixed sleeve 14 and the limiting shaft body 15. When the transmission shaft body 121 corresponding to the acting disc frame 10 inside the mounting disc frame one 71 contacts the bottom of the filter sleeve 4, the bottom of the filter sleeve 4 will apply a force to the transmission shaft body 121, causing the transmission shaft body 121 to move upward under the action of the force. Then, the telescopic shaft body 122 on the transmission shaft body 121 will move along the track of the arc groove body 132. It should be noted that since a guide panel 134 is installed at the intersection of the arc groove body 132 and the vertical groove body 131, and the guide panel 134 is an inclined surface on one side of the vertical groove body 131 and a right-angle surface on one side of the arc groove body 132, under the guiding action of the right-angle surface of the guide panel 134, the telescopic shaft body 122 moves along the track of the arc groove body 132, that is, the transmission shaft body 121 moves upward and makes an angle adjustment action. Since the transmission shaft body 121 is rotatably connected to the bottom of the acting disc frame 10, the acting disc frame 10 will move upward with the transmission shaft body 121. The force-applying shaft body 16 on the acting disc frame 10 will apply a force to the force-receiving rod frame 76 during the upward movement, so that the force-receiving rod frame 76 is affected by the force and drives the crushing blade 73 to make an angle adjustment through the annular disc frame 75. When the transmission shaft body 121 completely enters the annular sleeve 12, at this time the telescopic shaft body 122 is located at the top of the arc groove body 132, and the crushing blade 73 has completed the angle adjustment. The adjusted crushing blade 73 is as shown in the attached Figure 6As shown, at this time, the crushing blades 73 form a platform shape. Through the crushing blades 73 that form a platform shape, some block-shaped tissue fragments can be driven to move upward. Since the crushing blades 73 are arranged obliquely in the initial state, it is convenient for the crushing blades 73 to penetrate into the bottom of the filter sleeve 4 during the descending process. Then, during the angle adjustment of the crushing blades 73, a certain amount of block-shaped tissue fragments are present on their surfaces. Subsequently, the electromagnetic group 85 gradually reduces its power supply. Under the action of the plastic spring 84, the magnetic panel 83 drives the mounting disc frame one 71 and the connecting part 8 on it to move upward through the connecting shaft body 82, that is, the transmission shaft body 121 leaves the bottom of the filter sleeve 4, and the transmission shaft body 121 will move downward under the action of gravity (in order to facilitate the reset of the transmission shaft body 121, a spring can be installed in the annular sleeve 12. Since the spring is a prior art component, the present invention does not describe it in detail). During the descending process of the transmission shaft body 121, the telescopic shaft body 122 will move along the track of the V-shaped clamping groove body 133. When the telescopic shaft body 122 on the transmission shaft body 121 descends to the lowest point of the V-shaped clamping groove body 133, it will be limited here. Then, at this time, the transmission shaft body 121 no longer performs the reset movement. Since the transmission shaft body 121 is rotatably connected to the action disc frame 10, the force application shaft body 16 on the action disc frame 10 still acts on the force receiving rod frame 76. At this time, the crushing blades 73 are still in a planar shape. Subsequently, the electromagnetic component is energized to generate a repulsive force on the magnetic panel 83, so that the connecting shaft body 82 drives the mounting disc frame one 71 to move upward. During this process, the fixed sleeve 14 on the mounting disc frame one 71 will drive the mounting disc frame two 72 to rotate through the limiting shaft body 15. When the mounting disc frame two 72 approaches the cover body 102, the transmission shaft body 121 in the mounting disc frame two 72 will contact the inner wall of the cover body 102. Then, the transmission shaft body 121 will repeat the movement of the transmission shaft body 121 (that is, the transmission shaft body 121 corresponding to the mounting disc frame one 71), that is, the cutting blade 74 performs angle adjustment. The adjusted cutting blade 74 is as shown in the appendix Figure 10As shown, subsequently, the electromagnetic component continues to increase the amount of electricity conducted. At this time, the second mounting disk frame 72 remains stationary at this position under the action of the inner wall of the cover body 102. Consequently, the first mounting disk frame 71 will drive the massive tissue fragments closer to the second mounting disk frame 72. During this process, the massive tissue fragments on the crushing blade 73 will come into contact with the cutting blade 74 and be crushed by it, thereby effectively achieving the purpose of crushing the massive tissue fragments. During this process, multiple crushings can be carried out by changing the amount of electricity conducted by the electromagnetic component. After the crushing is completed, the power unit 6 is used to rotate the cutting blade 74, causing the massive tissue fragments on it to rotate and be thrown onto the inner wall surface of the filter sleeve 4 under the action of centrifugal force. The massive tissue fragments that have been crushed into small sizes can enter the drainage tube 2. When it is necessary to restore the cutting blade 74 and the crushing blade 73 to their initial positions, the amount of electricity conducted by the electromagnetic component can be appropriately reduced so that the transmission shaft body 121 no longer contacts the inner wall of the cover body 102. Subsequently, by increasing the amount of electricity conducted by the electromagnetic component, the telescopic shaft body 122 on the transmission shaft body 121 enters the vertical groove body 131 from the V-shaped clamping groove body 133. Correspondingly, to restore the crushing blade 73 to its initial state, the electromagnetic group 85 is powered off, and it moves downward under the action of the plastic spring 84. As a result, the transmission shaft body 121 contacts the bottom of the filter sleeve 4, causing the telescopic shaft body 122 to enter the vertical groove body 131 from the V-shaped clamping groove body 133. Subsequently, the electromagnetic component continues to be powered on, causing the connecting shaft body 82 to drive the first mounting disk frame 71 and the mechanical components thereon (including the cutting blade 74, the second mounting disk frame 72, the crushing blade 73, etc.) to return to their initial positions. It should be noted that when the telescopic shaft body 122 enters the vertical groove body 131, it will move towards its initial position under the action of gravity. During this process, it passes through the inclined surface of the guiding panel 134, and the force-applying shaft body 16 on the acting disk frame 10 does not exert a force on the force-receiving rod frame 76. That is, the annular disk frame 75 causes the cutting blade 74 and the crushing blade 73 to return to their inclined states under the action of the torsion spring 77. Thus, through the structural design of the present invention, the massive tissue fragments that cause blockage in the drainage tube 2 can be effectively crushed.
