Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a neurosurgical suction device with electrocoagulation function. Background Technology

[0002] A suction device is used to remove bleeding, exudate, pus, and contents of thoracic organs during surgery, making the surgical procedure clearer and reducing the chance of contamination. The principle of the suction device is very simple: it creates a negative pressure state at its suction head through a certain method. This atmospheric pressure forces the material outside the suction head towards the suction head, thus achieving the "suction" effect. In neurosurgery, a suction device can remove secretions and tissues, and can also be used for electrocoagulation hemostasis.

[0003] The "Rotable Electrocoagulation Aspirator" disclosed in application number "201921399293.X" includes a fixed disc, a first through tube, and a second through tube. A rotating block is installed on one side of the fixed disc via a rotating groove. A rotating handle is welded to one end of the rotating block. The bottom end of the rotating block is located inside the fixed disc. A contact block is welded to one end of the outer side of the rotating block. A first tactile switch and a second tactile switch are respectively installed at both ends of the contact block via screws. A first connecting block is connected to one end of the fixed disc via a hollow tube. A second connecting block is provided at one end of the first connecting block. A tube body is connected to one end of the second connecting block. An inner shell is provided inside the tube body. One end of the tube body communicates with the first through tube. This utility model facilitates switching between electrocoagulation and aspiration. During electrocoagulation, it can easily protect surrounding tissues from burning. It also allows for disassembly of the tube body and has good anti-slip properties, making it suitable for widespread promotion and use.

[0004] However, the above method still has the following drawbacks: the tube and electrocoagulation electrode pads can achieve sound absorption and electrocoagulation in neurosurgery, but the length of the tube is not adjustable, making it difficult to adjust its extension length, resulting in poor flexibility. In addition, the tube needs to be fixed with screws, and the tube needs to be loosened before it can be disassembled and cleaned, making the operation cumbersome. Utility Model Content

A one-way flow component 14 for preventing backflow of flushing fluid is provided at the bottom of the flushing pipe 12. Flushing fluid is introduced through the flushing pipe 12. The flushing fluid can pressurize the one-way flow component 14 and enter the inside of the housing 1. It can also be output through the conduit 3 and the sleeve 6. Flushing of the inside of the housing 1 can be carried out without disassembly. The operation is simple. By sealing the negative pressure pipe 11 with the sealing component 13, the inflow of flushing fluid can be prevented. After the inside of the housing 1 is cleaned, the input of flushing fluid is stopped. The one-way flow component 14 can be reset and can seal the flushing pipe 12. When the sleeve 6 aspirates secretions and tissues, it can prevent the entry of external gas.

[0028] In this embodiment, preferably, the limiting component 7 includes an arc-shaped plate 701. One side of the arc-shaped plate 701 is fixedly connected to one end of the sleeve 6. The arc-shaped plate 701 is sleeved on the surface of the conduit 3. A rubber pad 702 is fixedly provided on the inner wall of the arc-shaped plate 701. Clamping plates 703 for clamping the conduit 3 are fixedly provided on both sides of the top end of the arc-shaped plate 701.

A sealing ring 1306 is engaged inside the groove 1305. By rotating the screw 1302 with the knob 1303, the screw 1302 can drive the sealing plug 1304 to move. The turntable 1307 and the limiting sleeve 1308 can prevent the torque of the screw 1302 from being directly transmitted to the sealing plug 1304. After passing through the negative pressure pipe 11, the sealing plug 1304 can be blocked to prevent the flushing fluid from entering the negative pressure pipe 11. By rotating the screw 1302 in the opposite direction with the knob 1303 to reset the sealing plug 1304, the negative pressure pipe 11 can be connected to the inside of the shell 1, and suction can be performed.

[0030] In this embodiment, preferably, the unidirectional flow assembly 14 includes a threaded cap 1401. The inner wall of the threaded cap 1401 is threadedly connected to the bottom end of the flushing pipe 12. A spring 1402 is engaged with the threaded cap 1401, and a plunger 1403 is engaged with the spring 1402. Both the bottom end of the plunger 1403 and the inner wall of the threaded cap 1401 are fixedly provided with locking posts 1406 that engage with the spring 1402. The plunger 1403 is slidably connected to the inner wall of the flushing pipe 12. The top and bottom are provided with grooves 1404, and sealing rings 1405 are engaged inside the grooves 1404. The plunger 1403 can be supported by the spring 1402. The plunger 1403 can block the flushing tube 12 and the sleeve 10. When suctioning secretions, it can prevent the entry of external gas. By inputting flushing fluid, the flushing fluid can compress the spring 1402 through the plunger 1403, which can open the sleeve 10 and allow the flushing fluid to enter the interior of the housing 1, ensuring the unidirectional flow of the flushing fluid.

[0031] In this embodiment, preferably, an anti-slip ring 4 is fixedly provided on one side of the conduit 3, and a thread is fixedly provided on one end of the conduit 3. A connecting pipe 2 is fixedly provided on one side of the housing 1. One end of the conduit 3 is threadedly connected to the inner wall of the connecting pipe 2 through the thread. The thread and the connecting pipe 2 facilitate the installation and disassembly of the conduit 3. The anti-slip ring 4 facilitates the rotation of the conduit 3. An annular groove is provided at the other end of the conduit 3. A rubber ring 5 is engaged inside the annular groove. The rubber ring 5 can seal the connection between the sleeve 6 and the conduit 3. A limiting block 17 is fixedly provided on the other side of the housing 1. A handle 18 is fixedly provided on the surface of the limiting block 17 by bolts. A nut is threadedly connected to the bolts. A limiting groove that engages with the limiting block 17 is provided at one end of the handle 18. An anti-slip sleeve 19 is provided on the surface of the handle 18. A baffle 20 is fixedly connected to one end of the anti-slip sleeve 19. The handle 18 facilitates the movement of the housing 1.

[0032] In this embodiment, preferably, the top end of the negative pressure pipe 11 is fixedly connected to a connector 15, and the top end of the flushing pipe 12 is fixedly connected to a connector 16. The negative pressure pipe 11 can be connected to a suction pump through the connector 15, and the flushing pipe 12 can be connected to a flushing pump through the connector 16.

[0033] In use, the negative pressure tube 11 is connected to the suction pump via connector 15. The suction pump can expel the air inside the housing 1, creating a negative pressure state inside. Under the action of negative pressure, the cannula 6 can aspirate secretions and tissues, thus achieving a cleaning effect. During neurosurgery, the electrocoagulation electrode 8 can perform electrocoagulation hemostasis. During operation, the housing 1 can be held by the handle 18 to maintain its stability. When it is necessary to adjust the telescopic length of the cannula 6, first loosen the adjusting screw 707, and then slide the cannula 6 to adjust the telescopic length of the cannula 6. After adjustment, tighten the adjusting screw 707 so that the clamp 703 applies pressure to the catheter 3. The rubber pad 702 can increase the friction between the arc plate 701 and the catheter 3, which can quickly fix the cannula 6 and prevent it from loosening and falling off, ensuring safety and reliability.

[0034] After the suction is completed, when it is necessary to clean the inside of the housing 1 and the sleeve 6, the screw 1302 is rotated by the knob 1303 of the sealing assembly 13. The screw 1302 can drive the sealing plug 1304 to move. The turntable 1307 and the limiting sleeve 1308 can prevent the torque of the screw 1302 from being directly transmitted to the sealing plug 1304. After passing through the negative pressure pipe 11, the sealing plug 1304 can be sealed. The flushing pipe 12 is connected to the flushing pump through the connector 2 16. The flushing liquid is input by the flushing pump. The flushing liquid can compress the spring 1402 through the plunger 1403 of the one-way flow assembly 14, which can open the sleeve 10. The flushing liquid can enter the inside of the housing 1, which can ensure the one-way flow of the flushing liquid. It can be discharged through the conduit 3 and the sleeve 6, thus completing the flushing activity. The sealing plug 1304 can prevent the flushing liquid from reaching the negative pressure pipe 11.

[0035] After rinsing, the spring 1402 can push the plunger 1403 to reset. The plunger 1403 can block the rinsing tube 12 and the sleeve 10, preventing the entry of external gas when suctioning secretions. By rotating the screw 1302 in the opposite direction by the knob 1303, the sealing plug 1304 can be reset, allowing the negative pressure tube 11 to communicate with the interior of the shell 1, enabling the suction of secretions.
