Technical Field
[0001] This utility model relates to the field of electrocoating hook technology, specifically an adjustable electrocoating hook. Background Technology
[0002] Electrocautery hooks are surgical tools commonly used in hospitals for electrocautery and electrocoagulation during surgical procedures. They are used for tissue separation, hemostasis, and cutting, offering good operability and safety. Hand-controlled electrocautery hooks are suitable for various deep surgical procedures and have wide applications in surgery, demonstrating good clinical efficacy. When using electrocautery hooks, it is necessary to carefully control the current intensity and electrocoagulation time to avoid excessive electrocoagulation that could cause tissue damage. It is also important to check whether the tip of the electrocautery hook is bent or broken to ensure the smooth progress of the surgical procedure. Electrocautery hooks are suitable for various surgical scenarios, such as deep tissue surgeries involving the cardiothoracic, gastrointestinal, hepatobiliary, and other organs. Furthermore, they are widely used for hemostasis in obstetric and gynecological surgeries.
[0003] However, it still has some drawbacks. For example, when using an adjustable electrocoagulation hook, because the electrocoagulation hook is of a fixed length, if the electrocoagulation hook is too long or too short, it will affect the surgical operation of medical staff. It is not conducive to medical staff to freely adjust the appropriate length for use, which reduces the versatility and comfort of using the electrocoagulation hook.
[0004] To address the aforementioned problems, this application proposes an adjustable electrocoagulation hook. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Please see Figures 1-4 This utility model provides a technical solution: an adjustable electrocoagulation hook, including a first operating rod 1, an adjusting device 2 fixedly connected to the inner wall of the first operating rod 1, the adjusting device 2 including an adhesive cylinder 8, a threaded sleeve 9, a threaded ring 10 and a rubber cylinder 11, the adhesive cylinder 8 fixedly connected to the inner wall of the first operating rod 1, the threaded sleeve 9 fixedly connected to the inner wall of the adhesive cylinder 8, the threaded ring 10 threadedly connected to the inner wall of the threaded sleeve 9, and the rubber cylinder 11 fixedly connected to one end of the threaded ring 10. By rotating and displacing the threaded ring 10 within the threaded sleeve 9, medical personnel can adjust the overall length of the device, and it is convenient for medical personnel to adjust the appropriate length for insertion into the patient's body.
[0022] In this embodiment, as Figure 1-2 As shown, one end of the first operating lever 1 is fixedly connected to a handle lever 6.
