Description

Technical Field

[0001] This invention relates to the field of electro-absorption needle technology, specifically to an electro-absorption needle. Background Technology

[0002] Electroacupuncture is a commonly used instrument in clinical surgery. Electroacupuncture, also known as high-frequency electroacupuncture, is a surgical electrical instrument that replaces mechanical scalpels for tissue cutting. It heats the tissue by generating a high-frequency, high-voltage current at the tip of the effective electrode, thereby separating and coagulating the tissue, achieving the purpose of cutting and hemostasis.

[0003] For example, a surgical electrocoagulation and electrosurgical device with suction function, such as the announcement number CN213641160U, includes an upper shell and a lower shell. A fixing cap is sleeved on one end of the upper shell and the lower shell, and an end cap is sleeved on the other end of the upper shell and the lower shell. A threaded joint is welded to one side of the outer wall of the end cap, and a through hole is opened inside the threaded joint. A suction port is opened on the side of the bottom outer wall of the lower shell near the fixing cap. A suction tube is inserted into the suction port, and one end of the suction tube is inserted into the through hole. An installation block is welded to one side of the inner wall of the lower shell, and an electrosurgical unit is inserted into the outer wall of one side of the installation block.

[0004] The existing technology has the following technical problems: When the existing electrosurgical device is used, it is equipped with a negative pressure pipeline to remove waste gas or blood generated during surgery. However, during surgery, some bone fragments or blood clots are inevitably generated. Therefore, under negative pressure, bone fragments or blood clots are easy to adhere to the port of the pipeline or get stuck inside the pipeline. When the suction port of the pipeline is blocked or the pipeline is blocked inside, it is easy to cause the subsequent negative pressure adsorption effect to fail.

[0005] Therefore, we proposed a cutting-type electrostatic needle to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a cutting and suction electrocautery needle to solve the problem mentioned in the background art. Currently available electrocautery devices on the market use an internal negative pressure pipeline to remove surgical waste gas or blood during surgery. However, during surgery, bone fragments or blood clots are inevitably generated. Therefore, under negative pressure, bone fragments or blood clots are easily attached to the port of the pipeline or stuck inside the pipeline. When the suction port of the pipeline is blocked or the pipeline is blocked inside, it is easy to cause the subsequent negative pressure suction effect to fail.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cutting and suction needle, comprising a housing and an electrode plate installed inside the housing. A power cord is connected to the side of the electrode plate, and a plug and socket at the end of the power cord are mutually inserted to conduct electricity. A conductive seat is installed at the end of the electrode plate away from the power cord, and an electric cutting head is installed on the conductive seat. One end of the electric cutting head extends out of the housing and passes through an insulating sleeve. A movable block is installed on the housing, and a negative pressure tube connected to a negative pressure suction device is installed on the movable block. The side of the movable block is connected to a rubber sleeve through a connecting tube, and an adsorption hole is opened on the side of the rubber sleeve facing the electric cutting head. The rubber sleeve is located inside a positioning ring, and a baffle plate that compresses the rubber sleeve is fixed inside the positioning ring. The movable block is connected to the housing through an elastic element to provide a restoring elastic force for the movable block.

[0008] Preferably, an electric cutting button and an electric coagulation button are provided above the electrode plate, and the conductive seat at the left end of the electrode plate is mated with the insertion part of the electric cutting head. The electric cutting head is made of conductive metal.

[0009] By adopting the above technical solution, when the electric cutting head and the conductive seat are inserted into each other, the electric cutting head can conduct electricity, which facilitates subsequent electric cutting or electrocoagulation operations using the energized electric cutting head.

[0010] Preferably, the electric cutting head is configured as an electric cutting blade.

[0011] Preferably, the electro-cutting head is configured as a peeler.

[0012] By adopting the above technical solution, the peeler can be installed on the conductive base to perform peeling operations when no electric cutting is being performed, and the peeler can also be used to perform electric cutting operations when the electric cutting button is pressed.

[0013] Preferably, the interior of the movable block is interconnected with the interior of the rubber sleeve via a connecting pipe, and the connecting pipe is a rigid pipe that can slide along the side of the outer shell.

[0014] By adopting the above technical solution, when negative pressure is generated inside the negative pressure tube, the negative pressure can be transmitted to the inside of the rubber sleeve through the moving block and the connecting tube, and the suction holes on the rubber sleeve can be used to remove surgical waste gas or blood.

[0015] Preferably, the surface of the rubber sleeve is evenly distributed with multiple adsorption holes, and the rubber sleeve can slide inside the positioning ring, and the rubber sleeve is in contact with the baffle in the initial state.

[0016] By adopting the above technical solution, when the rubber sleeve moves inside the positioning ring, the baffle plate can squeeze the rubber sleeve. The baffle plate can scrape off the blood clots or bone fragments attached to the surface of the rubber sleeve. At the same time, after the rubber sleeve is compressed, some of the airflow inside can also be ejected outward, thereby playing an auxiliary role in unblocking the adsorption hole.

[0017] Preferably, a movable buckle is installed on the outer side of the movable block, and the movable block is connected to the adjusting plate on the inner side of the movable block. The outer surface of the movable buckle is provided with anti-slip texture, and the adjusting plate is provided with a docking hole.

[0018] By adopting the above technical solution, the anti-slip texture on the surface of the movable buckle can improve the contact wear with the human hand, and the setting of the docking hole can connect with the end opening of the connecting tube.

[0019] Preferably, the adjusting plate and the movable buckle can rotate outside and inside the moving block respectively, and a sealing gasket is provided between the adjusting plate, the movable buckle and the moving block. The moving block can slide on the outer shell. The mating holes on the adjusting plate correspond one-to-one with the connecting pipes. In the initial state, one of the mating holes on the adjusting plate is aligned with the opening of the end of the connecting pipe on the side of the moving block, and the other mating hole on the adjusting plate is misaligned with the opening of the end of the other connecting pipe on the side of the moving block in the initial state.

[0020] By adopting the above technical solution, through the misalignment and alignment of the docking hole and the pipe connected to the moving block, only one connecting pipe works when adsorbing waste gas or blood.

[0021] Preferably, a limiting component is installed on the movable buckle. The limiting component includes a plug rod inserted into the movable buckle, and the plug rod is connected to the movable buckle through an auxiliary spring. The end of the plug rod is inserted into a guide hole opened on the movable block.

[0022] By adopting the above technical solution, the movable buckle can be limited and fixed by inserting the plug rod into the guide hole on the moving block.

[0023] Preferably, the plug rod forms an elastic telescopic structure through an auxiliary spring and a movable buckle, and the outer wall of the end of the plug rod and the inner wall of the guide hole opened on the moving block fit together, and multiple guide holes are evenly distributed on the moving block.

[0024] By adopting the above technical solution, the auxiliary spring can be reset and rebound after the auxiliary spring moves on the movable buckle. At the same time, the outer wall of the end of the plug rod and the inner wall of the guide hole fit together, which can improve the stability of the plug rod in the guide hole.

[0025] Compared with the prior art, the beneficial effects of the present invention are: the cutting and suction needle integrates the negative pressure suction tube with the cutting and suction needle into one unit, allowing the surgeon to perform simultaneous electro-cutting and suction operations by a single person. At the same time, during the suction process, the suction port of the tube can be blocked or unblocked, and multiple channels are set up. However, if one suction channel is blocked, it will not affect the use of the other suction channel. 1. The electric cutting head and the conductive base are detachably connected. An electric cutting blade or a peeler can be inserted into the conductive base for use. When the peeler is inserted into the conductive base, it can perform normal peeling operations when electric cutting is not required. When the electric cutting button is pressed, the normal electric cutting function will not be affected because the peeler is made of conductive metal. 2. By setting a movable block on the outer shell, and connecting the movable block to the negative pressure device through a negative pressure pipe, the negative pressure adsorption, electro-resection, and electrocoagulation operations are integrated into one unit during surgery. One surgeon can perform adsorption and electro-resection operations, improving the overall surgical efficiency. At the same time, after the movable block moves, it can pull the rubber sleeve to move synchronously through the connecting pipe. After the rubber sleeve moves, it can squeeze the baffle plate. The deformed rubber sleeve can squeeze the internal airflow out through the adsorption hole, thereby using the squeezed airflow to assist in unblocking. At the same time, the deformed rubber sleeve is in close contact with the baffle plate, and the baffle plate can scrape away the bone debris attached to the rubber sleeve. 3. The rotation of the movable buckle can drive the adjustment plate inside the moving block to rotate synchronously. The rotation of the adjustment plate can cause the docking hole to misalign and overlap with the connecting tube. This makes it convenient to switch the connecting tube during surgery. If one connecting tube is blocked, it can be quickly switched to another connecting tube for use. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figures 1-10Existing electrosurgical devices, when used, employ internal negative pressure tubing to remove surgical waste gas or blood during surgery. However, during surgery, bone fragments or blood clots inevitably form. Therefore, under negative pressure, these fragments or clots easily adhere to the tubing ports or become stuck inside the tubing. When the suction port or the tubing is blocked, the subsequent negative pressure suction effect is compromised. To address this technical problem, this embodiment discloses the following: an electrosurgical needle comprising a housing 1 and an electrode plate 3 installed inside the housing 1. A power cord 2 is connected to the side of the electrode plate 3. The plug and socket at the end of the power cord 2 are interlocked for electrical conduction. A conductive base 6 is installed at the end of the electrode plate 3 away from the power cord 2, and an electrosurgical head 7 is mounted on the conductive base 6. The end of the electrosurgical head 7 extending out of the housing 1 passes through an insulating sleeve 8. A movable block 10 is mounted on the housing 1, and a negative pressure device connected to the negative pressure suction device is mounted on the movable block 10. The tube 11 and the side of the moving block 10 are connected to each other by the connecting tube 12 and the rubber sleeve 13. The rubber sleeve 13 has an adsorption hole 14 on the side facing the electric cutting head 7. The rubber sleeve 13 is located inside the positioning ring 9, and a baffle 15 that compresses the rubber sleeve 13 is fixed inside the positioning ring 9. The moving block 10 is connected to the outer shell 1 by an elastic element 16 to provide the moving block 10 with a reset elastic force. The electric cutting button 4 and the electric coagulation button 5 are provided above the electrode plate 3, and the conductive seat 6 at the left end of the electrode plate 3 is... The electric cutting head 7 is made of conductive metal and is configured as an electric cutting blade 701. The interior of the moving block 10 is connected to the interior of the rubber sleeve 13 through the connecting pipe 12. The connecting pipe 12 is a rigid pipe and can slide on the side of the outer shell 1. The surface of the rubber sleeve 13 has a plurality of suction holes 14 evenly distributed, and the rubber sleeve 13 can slide inside the positioning ring 9. In the initial state, the rubber sleeve 13 is in contact with the baffle plate 15.

[0030] During surgery, the electrocautery head 7 is inserted into the conductive base 6 on the side of the electrode plate 3. Then, the power cord 2 is plugged into the socket. By pressing the electrocautery button 4 or electrocoagulation button 5 on the outer casing 1, electrocautery or electrocoagulation is performed using the electrocautery head 7. Simultaneously, the negative pressure tube 11 is connected to the negative pressure device. Utilizing the negative pressure generated by the device, the moving block 10, connecting tube 12, rubber sleeve 13, and suction hole 14 can remove waste gas or blood generated during surgery. This integrates suction, electrocautery, and electrocoagulation functions, avoiding the need for the surgeon to use a separate negative pressure device when performing surgery with an electrocautery needle. During surgery, bone fragments or blood clots are inevitably generated. When these fragments or clots adhere to the suction hole 14 on the rubber sleeve 13, they can easily clog the suction hole 14. The movable block 10 can be pushed on the outer shell 1. After the movable block 10 moves, it can drive the side connecting pipe 12 to move synchronously. After the connecting pipe 12 moves, it can also pull the end rubber sleeve 13 to move inside the positioning ring 9. Since the rubber sleeve 13 and the baffle 15 are in contact with each other, when the rubber sleeve 13 moves towards the baffle 15, the baffle 15 can first squeeze the rubber sleeve 13. After the rubber sleeve 13 is compressed, the airflow inside can be squeezed out through the adsorption hole 14. The squeezed airflow can also play an auxiliary role in unblocking the bone fragments stuck in the adsorption hole 14. When the rubber sleeve 13 moves relative to the baffle 15, the rubber sleeve 13 deforms and sticks tightly to the baffle 15. At this time, the baffle 15 can also scrape off the bone fragments or blood clots attached to the rubber sleeve 13, thereby reducing the possibility of pipe blockage.

[0031] The electro-cutting head 7 is set as a peeler 702.

[0032] Before performing the cutting and suction operation, the electro-cutting blade 701 can be pulled out from the conductive seat 6 on the side of the electrode plate 3. Then, the insertion part of the peeler 702 can be inserted into the conductive seat 6 on the side of the electrode plate 3 to complete the adjustment of the electro-cutting head 7. When the peeler 702 is used as the head, the peeler 702 can be used to perform normal peeling operations when electro-cutting or electrocoagulation operations are not required. At the same time, since the peeler 702 itself is also made of conductive metal, pressing the electro-cutting button 4 or the electrocoagulation button 5 will not affect the normal electro-cutting or electrocoagulation operation.

[0033] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. During blood aspiration in surgery, the blood may become clogged due to bone fragments or blood coagulation. To improve surgical efficiency, this example discloses the following technical content: Figure 3 and Figures 6-10As shown, a movable retaining ring 17 is installed on the outer side of the movable block 10, and the movable block 10 is connected to the adjusting plate 18 on the inner side of the movable block 10. The outer surface of the movable retaining ring 17 is provided with anti-slip texture in the circumferential direction. The adjusting plate 18 is provided with a docking hole 19. The adjusting plate 18 and the movable retaining ring 17 can rotate on the outside and inside of the movable block 10, respectively. A sealing gasket is provided between the adjusting plate 18, the movable retaining ring 17 and the movable block 10. The movable block 10 can slide on the outer shell 1. The docking holes 19 on the adjusting plate 18 correspond one-to-one with the connecting pipes 12. In the initial state, one of the docking holes 19 on the adjusting plate 18 is aligned with the end opening of the connecting pipe 12 on the side of the movable block 10. Another docking hole 19 on the 8 is initially misaligned with the opening at the end of another connecting pipe 12 on the side of the moving block 10. A limiting component 20 is installed on the movable retaining ring 17. The limiting component 20 includes a plug rod 201 inserted into the movable retaining ring 17. The plug rod 201 is connected to the movable retaining ring 17 through an auxiliary spring 202. The end of the plug rod 201 is inserted into a guide hole 203 opened on the moving block 10. The plug rod 201 forms an elastic telescopic structure through the auxiliary spring 202 and the movable retaining ring 17. The outer wall of the end of the plug rod 201 and the inner wall of the guide hole 203 opened on the moving block 10 fit together. There are multiple guide holes 203 evenly distributed on the moving block 10.

[0034] During surgical procedures, the movable block 10 is connected to the negative pressure tube 11. The negative pressure generated inside the tube 11 allows for the removal of surgical waste gas or blood through the suction holes 14 on the side of the rubber sleeve 13, thus preventing interference with the surgeon's operation. When one of the connecting tubes 12 on the side of the movable block 10 becomes blocked, the surgeon first pulls the insertion rod 201 to disengage its end from the guide hole 203 on the movable block 10. Then, the surgeon rotates the movable retaining ring 17 on the movable block 10. The rotation of the retaining ring 17 causes the inner adjusting plate 18 to rotate synchronously. The rotation of the adjusting plate 18 then drives the docking hole 19 on it. The device is rotated so that one of the docking holes 19 on the adjusting plate 18 is misaligned with the end opening of the blocked connecting tube 12, while the other docking hole 19 is aligned with the end opening of the unblocked connecting tube 12. After the movable retaining ring 17 is rotated into place, the insertion rod 201 is released. The insertion rod 201 returns to its original position under the action of the auxiliary spring 202. The returned insertion rod 201 is reinserted into the guide hole 203 on the moving block 10, thereby fixing the position of the movable retaining ring 17. By switching the connecting tubes 12, if one of the tubes is blocked during the operation, it can be quickly switched to use the unblocked tube for suction, thereby improving the overall surgical efficiency.
