Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrocautery hook technology, and in particular to a coarse electrocautery hook for open surgery that is attractive, flexible, and has a low-temperature coating. Background Technology
[0002] Currently, there are no readily available suction-operated electrocautery hooks for open surgery. Right-angle forceps are still used to dissect tissue and blood vessels, with an assistant performing electrocoagulation and cutting using an electrocautery scalpel. Right-angle forceps are commonly used for dissection in surgical procedures, and electrocautery hooks evolved from them, incorporating electrodes and suction capabilities. They are now widely used in laparoscopic surgery. However, current electrocautery hooks share a common drawback: they cannot be bent, and the magnifying effect of a laparoscope often results in hooks with relatively small diameters. Therefore, electrocautery hooks are still necessary in open surgery, but with different requirements than in laparoscopic surgery: 1. The length cannot be too long, as this hinders operation, as in superficial surgeries such as breast cancer and thyroid surgery; 2. The diameter cannot be too small, because open surgery involves more complex procedures, such as those dealing with more severe adhesions, which generate more smoke and thicker pus during cutting; 3. The diameter of the hook cannot be too small, otherwise it can easily damage blood vessels. Utility Model Content

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0019] like Figure 1 As shown, this embodiment provides an aspirable, flexible open surgical thick electric hook with a low-temperature coating, which consists of an electric hook body, a copper flexible tube 3, a steel tube 4, and an electrode 6.
[0020] The electrocautery hook body includes an integrally connected connecting part 1 and a right-angled electrocautery hook part 2. The outer periphery of the right-angled electrocautery hook part 2 is provided with irregular barbs and coated with a low-temperature coating. This low-temperature coating includes a heat-insulating layer and a Teflon anti-adhesion layer arranged from the inside out. The electrocautery hook generates very high temperatures during coagulation, ranging from 60-100℃ in electrocoagulation mode, primarily used for hemostasis and tissue coagulation. Accidental damage to blood vessels or organs can cause thermal injury. Therefore, local cooling is necessary to reduce thermal side effects from the electrocautery hook. The mixed coating of the heat-insulating layer and the Teflon anti-adhesion layer, especially during electrocoagulation, results in a low local temperature, reducing scab formation and mitigating postoperative adhesions.
[0021] The electric hooks used in open surgery require a thicker diameter. Therefore, the diameter of the right-angle electric hook part 2 is 1.2 mm, which is similar to the diameter of a right-angle clamp. It is used for tissue separation, hemostasis, and cutting.
[0022] The right-angle electric hook part 2 is integrally fixedly mounted on the end wall of one end of the connecting part 1. The other end of the connecting part 1 is fixedly connected to one end of the copper flexible tube 3, and the other end of the copper flexible tube 3 is fixedly connected to the steel pipe 4. The connecting part 1, the copper flexible tube 3, and the steel pipe 4 are all wrapped by an insulating flexible tube 5. The electric hook body, the copper flexible tube 3, and the steel pipe 4 constitute the entire open surgical thick electric hook, which is 25cm long and suitable for open surgery. The copper flexible tube 3 can be bent in any direction; it cannot be too soft or too stiff: too soft is not conducive to tissue dissection, and too stiff prevents bending.
[0023] A protrusion 4a is provided on the steel pipe 4, and the protrusion 4a is fixedly connected to the electrode 6. The electrode 6 passes through the insulating hose 5 and is used to connect to AC power for foot-operated electrocoagulation.
[0024] An inclined suction inlet 8 is provided at one end of the connecting part 1 near the right-angle electric hook part 2. A channel one is provided inside the connecting part 1, a channel two is provided inside the copper flexible hose 3, and a channel three is provided inside the steel pipe 4. Channels one, two, and three are interconnected to form a fluid suction channel 7. The inclined suction inlet 8 serves as the inlet of the fluid suction channel 7, and the outlet of the fluid suction channel 7 is connected to a suction device for attracting gases and various liquids, even viscous liquids. The inner diameters of channels one, two, and three are the same, all being 5mm. The wall thickness of the connecting part 1, the copper flexible hose 3, and the steel pipe 4 is all 1mm.
[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model using the disclosed methods and techniques, or modify it into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of this utility model. Therefore, all equivalent changes made based on the shape, structure, and principle of this utility model without departing from its technical solution should be covered within the protection scope of this utility model.
