Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a bipolar electrocoagulation forceps. Background Technology

[0002] Bipolar electrocoagulation forceps are a commonly used surgical instrument in modern medicine. Existing bipolar electrocoagulation forceps typically consist of an open forceps tip, an insulated forceps shaft, and a fixing base. A plug at the rear of the fixing base connects to an external host unit via a wire. Because the forceps shaft is insulated, current is conducted only between the forceps tips. When performing precise electrocoagulation hemostasis and treatment on small blood vessels and other structures, the high-frequency current between the two forceps tips generates heat, causing the held tissue proteins to coagulate, thereby achieving hemostasis or sealing of small blood vessels.

[0003] Traditional bipolar electrocautery forceps allow for adjustable forceps tip spacing, but in cases of large-area bleeding, it's difficult to precisely control the area affected by clotting each time, hindering rapid and efficient hemostasis. Furthermore, in confined surgical spaces (such as between closely spaced nerves or tissues), the forceps tips cannot precisely and efficiently clot and form scabs on the wound tissue. This can lead to healthy nerves or tissues sticking to the forceps tips, failing to provide accurate protection. Removing the forceps can then damage these healthy nerves or tissues, negatively impacting the surgical outcome. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The purpose of this invention is to provide a bipolar electrocoagulation forceps to solve the problems existing in the prior art, which can efficiently and quickly stop bleeding in wounds and improve surgical efficiency and surgical results.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] This invention provides a bipolar electrocoagulation forceps, such as Figure 1-4 As shown, the device includes a fixing base 1, two forceps bodies, and an insulating limiting member 5. Each forceps body comprises a forceps body and forceps tips 4. One end of the forceps body is fixedly connected to the forceps tip 4, and the other end is connected to a high-frequency input head 6. The ends of the two forceps bodies furthest from the forceps tip 4 are fixedly connected to the fixing base 1. The insulating limiting member 5 is fixedly connected to the two forceps bodies on both sides, and is used to limit the distance between the two forceps tips 4. By limiting the distance between the two forceps tips 4 through the insulating limiting member 5 connected between the two forceps bodies, the area of ​​coagulation action can be precisely controlled each time, ensuring a fixed coagulation area each time, shortening the interval between coagulation actions, achieving rapid and efficient hemostasis, and improving surgical efficiency and outcome.

[0029] In a further preferred embodiment of this invention, the bipolar electrocoagulation forceps also includes an insulating layer 12, which covers the outer surface of the forceps body. The top surface and two sides of the forceps tip 4 are also covered with the insulating layer 12. The insulating layer 12 on the outer surface of the forceps body effectively prevents current from being conducted from the forceps body to other parts of the body, ensuring the safety of the surgeon and the patient. The insulating layer 12 on the top surface and two sides of the forceps tip 4 ensures that only the bottom surface of the forceps tip 4 can conduct current, facilitating rapid and efficient localized coagulation of the tissue below the forceps tip 4. At the same time, the insulating layer 12 effectively protects the healthy tissue above the forceps tip 4, achieving precise localized coagulation, preventing healthy tissue from sticking to the forceps tip 4, and improving surgical efficiency.

[0030] In a further preferred embodiment of this utility model, the insulating limiting member 5 includes two fixing parts 9 and a middle part 10. The fixing parts 9 are fixedly connected to the forceps body, and the two ends of the middle part 10 are respectively fixedly connected to the two fixing parts 9. The middle part 10 is disposed in the gap between the two forceps bodies. Preferably, the two fixing parts 9 are respectively fixed to one end of the forceps body near the forceps tip 4, and the middle part 10 between the two fixing parts 9 is a thin sheet that can extend towards the forceps tip 4 to fill the gap between the two forceps tips 4. When coagulating one of two closely adhering tissues, the thin sheet between the two forceps tips 4 can separate the two tissues, precisely protecting the healthy tissue, and then coagulating the tissue requiring surgery, ensuring the surgical effect. Preferably, the insulating limiting member 5 can be made of PA66 plastic material, or other insulating materials can be used.

[0031] In a further preferred embodiment of this utility model, the tweezers body includes a tweezers bar 3 and a tweezers handle 2. One end of the tweezers bar 3 is fixedly connected to the tweezers tip 4, and the other end of the tweezers bar 3 is fixedly connected to the tweezers handle 2. The end of the tweezers handle 2 away from the tweezers bar 3 is connected to the high-frequency input head 6, and the ends of the two tweezers handles 2 away from the tweezers bar 3 are fixedly connected by a fixing seat 1.

[0032] A further preferred embodiment of this utility model is, as follows: Figure 5 As shown, a forceps bar 3 has a first water channel, and a forceps tip 4 connected to it has a second water channel communicating with the first water channel. The bottom surface of the forceps tip 4 has a water outlet 8 communicating with the second water channel. The end of the first water channel furthest from the second water channel is connected to and communicates with a dripping device 7. When using bipolar electrocoagulation forceps for surgery, heat is generated, leading to excessively high tissue temperature and thermal damage. The dripping device 7 continuously drips an appropriate amount of saline solution through the water outlet 8 to cool the electrocoagulation site, lower tissue temperature, reduce tissue damage, and prevent eschar formation. The saline solution also washes away impurities, maintaining a clear surgical field.

[0033] In a further preferred embodiment of this utility model, the insulating layer 12 is made of PA66 plastic material.

[0034] In a further preferred embodiment of this utility model, the tweezer handle 2 and the high-frequency input head 6 are integrally formed using powder metallurgy.

[0035] In a further preferred embodiment of this utility model, the tweezers bar 3 is made of stainless steel material with high electrical and thermal conductivity.

[0036] In a further preferred embodiment of this utility model, since the bipolar electrocoagulation forceps of this application have a short interval between each coagulation, the stainless steel forceps tip 4 will sinter due to the high frequency of multiple electrocoagulation actions. Therefore, the forceps tip 4 made of silver alloy material with high conductivity and high thermal conductivity can meet the requirements of multiple rapid coagulation.

[0037] In a further preferred embodiment of this utility model, the tweezers handle 2 is provided with an anti-slip part 11, which can ensure that the operator holds it more securely.

[0038] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
