Abstract
Description
Technical Field
[0001] This utility model relates to the field of surgical instruments for the digestive tract, specifically to a hemostatic forceps with an electrocautery knife. Background Technology
[0002] Gastrointestinal tumors are among the most common malignant tumors in China. As a country with a high incidence of gastrointestinal tumors, my country commonly performs ESD (endoscopic submucosal dissection). ESD is a minimally invasive procedure that allows for the complete removal of diseased mucosa located in the submucosa using an endoscope. Currently, ESD procedures involve using an electrocautery knife and hemostatic forceps separately, making the operation complex and affecting efficiency. Utility Model Content
[0003] Technical objective: To address the shortcomings of existing ESD procedures, this utility model discloses a hemostat with an electrosurgical unit that includes an electrosurgical unit and a hemostat, which can improve the efficiency of ESD procedures.
[0004] Technical solution: To achieve the above technical objectives, the present invention adopts the following technical solution:
[0005] A hemostat with an electrosurgical knife includes a forceps head, an outer tube, and an operating handle. The electrosurgical knife is inserted into the operating handle, and its end passes through the outer tube and is located between the two arms of the forceps head. A first slider and a second slider are respectively provided on the operating handle for operating the opening and closing of the forceps head and the movement of the electrosurgical knife.
[0006] Preferably, the pliers of this utility model include a fixed arm that is fixed relative to the outer tube and a rotating arm that is rotatably connected to the fixed arm. A driving component is connected between the end of the rotating arm and the first slider. The rotating arm is driven to rotate by the first slider push-pull driving component to realize the opening and closing of the pliers.
[0007] Preferably, the end of the fixed arm of this invention is provided with a pliers groove for cooperating with the electric knife, and the pliers groove guides the forward and backward movement of the electric knife.
[0008] Preferably, the driving component of this utility model includes a driving block, on which a pin is provided, and on the rotating arm a sliding groove for cooperating with the pin. When the driving block moves, the rotating arm rotates relative to the fixed arm by the movement of the pin in the sliding groove.
[0009] Preferably, the control electrode of the electrosurgical unit of this invention is fixed on the operating handle and located on the side where the second slider slides.
[0010] Beneficial effects: This utility model controls the opening and closing of the clamp head and the movement of the electrosurgical unit by using different sliders on the operating handle, so that the two can work synchronously without the need for instrument exchange, which can reduce bleeding and other problems during the operation. At the same time, one of the clamp arms of the clamp head is set as a fixed arm, and the clamp head groove on the fixed arm is used to guide and limit the movement of the electrosurgical unit, which improves the stability of the electrosurgical unit during operation.

[0016] Reference will now be made in detail to embodiments of the present disclosure, one or more of which are set forth herein. Each embodiment and example is provided by way of explanation of the apparatus, composition, and materials of the present disclosure, and not by way of limitation. Rather, the following description provides convenient illustrations for implementing exemplary embodiments of the present disclosure. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made to the teachings of the present disclosure without departing from the scope or spirit of the present disclosure.
[0017] like Figures 1-3 As shown, this utility model discloses a hemostatic forceps with an electrosurgical knife, including a forceps head 1, an outer tube 2, and an operating handle 3. The electrosurgical knife 4 is inserted into the operating handle 3, and the end of the electrosurgical knife 4 passes through the outer tube 2 and is located between the two arms of the forceps head 1. A first slider 5 and a second slider 6 are respectively provided on the operating handle 3 for operating the opening and closing of the forceps head 1 and the movement of the electrosurgical knife 4. The control electrode 13 of the electrosurgical knife 4 is fixed on the operating handle 3 and is located on the side where the second slider 6 slides.
[0018] During use, the electric knife 4 moves within the opening and closing range of the pliers head. To ensure operational stability, such as... Figure 2 and Figure 3As shown, the clamp head 1 of this utility model includes a fixed arm 7 fixed relative to the outer tube 2 and a rotating arm 8 rotatably connected to the fixed arm 7. A driving component is connected between the end of the rotating arm 8 and the first slider 5. The rotating arm 8 is rotated by the first slider 5 through the push-pull driving component to realize the opening and closing of the clamp head 1. The end of the fixed arm 7 is provided with a clamp head groove 9 for cooperating with the electrosurgical knife 4. The clamp head groove 9 guides the forward and backward movement of the electrosurgical knife 4. The fixed arm 7 can effectively support the electrosurgical knife 4, enhance stability, so that the instrument can be operated stably during the operation and improve efficiency.
[0019] The driving assembly of this utility model includes a driving block 10, on which a pin 11 is provided, and a sliding groove 12 for cooperating with the pin 11 is provided on the rotating arm 8. When the driving block 10 moves, the rotating arm 8 is driven to rotate relative to the fixed arm 7 by the movement of the pin 11 in the sliding groove 12. The driving assembly can be replaced by other forms of driving the corresponding clamp arm to rotate in the prior art.
[0020] This invention eliminates the need for instrument replacement during use, ensuring surgical continuity. It also boasts excellent structural stability, with the electrosurgical unit and forceps controlled by separate sliders, allowing for instrument switching as needed. This effectively improves ESD surgical efficiency and reduces issues such as bleeding during the procedure.
