Description

Technical Field

[0001] This disclosure relates to high-frequency electrosurgical instruments, and more specifically, to a bipolar electrocoagulation forceps. Background Technology

[0002] High-frequency electrosurgical instruments are typically used in surgery to convert and deliver ultrasonic energy into biological tissue. The resulting mechanical vibration and thermal effect cause the hydrogen bonds in tissue proteins to break, leading to protein denaturation and coagulation. This mechanical and thermal energy is particularly useful for tissue coagulation, hemostasis, and cutting. In surgical instruments, a high-frequency generator produces high-frequency electrical energy, which is then converted into mechanical vibration energy by piezoelectric or electromagnetic compressive materials in the transducer. This vibration energy is then amplified and transmitted to the distal end of the instrument. The use of radiofrequency effects in surgery has a long history. Bipolar electrocoagulation forceps are widely used in various surgical procedures. They utilize the thermal effect of the high-frequency current generated by the radiofrequency generator to dehydrate, coagulate, break, and separate tissue, achieving the surgical objective.

[0003] Conventional high-frequency electrosurgical instruments have fixed handles that are difficult to disassemble. When blood or bodily fluids enter the instrument during surgery, they can damage the internal control components. In addition, most high-frequency electrosurgical instruments that are difficult to disassemble are disposable, which can lead to waste of resources and high surgical costs. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a bipolar electrocautery forceps, including a detachable part, which can be disassembled for cleaning when the inside of the instrument is contaminated, thus ensuring the safety and effectiveness of the instrument.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bipolar electrocautery clamp includes an actuator assembly, a lever assembly, a control assembly, and a housing assembly. The actuator assembly is located at one end of the lever assembly, and the control assembly is located at the other end of the lever assembly away from the actuator assembly. The housing assembly includes a first housing and a second housing, which are detachably connected by a magnetic attraction assembly. The actuator assembly, lever assembly, and control assembly can be assembled into a single structure, and the first housing and the second housing, after being connected, at least partially cover the control assembly.

[0007] Preferably, the magnetic attraction assembly includes 1 to 7 magnetic snap pairs, each magnetic snap pair including a first magnetic snap disposed on the inner side of the first housing and a second magnetic snap disposed on the inner side of the second housing, wherein the first magnetic snap and the second magnetic snap are magnetically attracted to each other.

[0008] Preferably, the inner side of the first housing is provided with a first mounting groove for installing the first magnetic buckle, and the inner side of the second housing is provided with a second mounting groove for installing the second magnetic buckle, the positions of the first mounting groove and the second mounting groove corresponding to each other.

[0009] Preferably, the control assembly includes a bracket, an actuator control mechanism, and a lever control mechanism.

[0010] Preferably, the bracket includes a first connecting plate and a second connecting plate, which are fixedly connected by bolts; the actuator control mechanism and the lever control mechanism are both connected between the first connecting plate and the second connecting plate.

[0011] Further optimized, the inner side of the first housing is provided with a first snap-fit ​​structure, and the first connecting plate is snapped into the first housing by the first snap-fit ​​structure; and / or, the inner side of the second housing is provided with a second snap-fit ​​structure, and the second connecting plate is snapped into the second housing by the second snap-fit ​​structure.

[0012] Further optimized, at least two magnetic snap pairs are provided, and the at least two magnetic snap pairs are divided into a first group of magnetic snap pairs and a second group of magnetic snap pairs, with the first group of magnetic snap pairs located above the integral structure and the second group of magnetic snap pairs located below the integral structure.

[0013] In a further optimized manner, the first housing has a first notch formed below the integral structure, and the second housing has a second notch formed below the integral structure. After the first housing and the second housing are connected, the first notch and the second notch are joined together to form a finger buckle.

[0014] Further optimized, the second set of magnetic buckle pairs includes at least two magnetic buckle pairs, in which at least one magnetic buckle pair is located below the finger buckle, and at least one magnetic buckle pair is located between the finger buckle and the integrated structure.

[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] like Figure 1-3As shown, this utility model provides a bipolar electrocoagulation forceps for high-frequency electrosurgery, including an actuator assembly 1, a lever assembly 2, a control assembly 3, and a housing assembly 4. The actuator assembly 1 is located at one end of the lever assembly 2, and the control assembly is located at the other end of the lever assembly 2 away from the actuator assembly 1. The actuator assembly 1 can be used to perform surgical operations in contact with human tissue, and the control assembly 3 can be used by the operator to control the lever assembly 2 and the actuator assembly 1. The housing assembly 4 includes a first housing 4-1 and a second housing 4-2, which can be detachably connected by magnetic attraction. The actuator assembly 1, the lever assembly 2, and the control assembly 3 can be assembled into a single structure, and the first housing 4-1 can cover the control assembly 3 after being connected to the second housing 4-2.

[0027] By adopting the above technical solution, when contaminants such as blood or body fluids enter the instrument during the operation, the first housing 4-1 and the second housing 4-2 can be disassembled in time to wipe the internal components, so as not to affect the subsequent operation process; or after the operation, the first housing 4-1 and the second housing 4-2 can be disassembled to disinfect and clean the internal components and components that come into contact with human tissue.

[0028] like Figure 6 As shown, the control assembly 3 includes a bracket 7, an actuator control mechanism, and a lever control mechanism. The actuator control mechanism is driven to the actuator assembly 1, and the lever control mechanism is driven to the lever assembly 2. The actuator control mechanism and the lever control mechanism are detachably connected to the bracket 7 by means of a slot, bolt, or other connection method that can achieve the same effect. After the first housing 4-1 and the second housing 4-2 are connected, they can completely cover the bracket 7 to ensure the safe use of the bipolar electrocautery forceps.

[0029] As one example, the bracket 7 includes a first connecting plate 7-1 and a second connecting plate 7-2. The first connecting plate 7-1 and the second connecting plate 7-2 can be fixedly connected by bolts, magnetic attraction, or adhesive. The actuator control mechanism and the rod control mechanism are both connected between the first connecting plate 7-1 and the second connecting plate 7-2.

[0030] As one example, the inner side of the first housing 4-1 may be provided with a first snap-fit ​​structure 8, and the first connecting plate 7-1 may be snap-fitted to the first housing 4-1 through the first snap-fit ​​structure 8. The first housing 4-1 and the first connecting plate 7-1 may also be fixedly connected by bolts. The second connecting plate 7-2 may be snap-fitted to the second housing 4-2 through the second snap-fit ​​structure, and the second housing 4-2 and the second connecting plate 7-2 may also be fixedly connected by bolts.

[0031] By adopting the above technical solution, both the actuator control component 3 and the lever control component 3 are mounted on the bracket 7, so that even after the first housing 4-1 and the second housing 4-2 are disassembled, the actuator control component 3 and the lever control component 3 still have components available for support, further ensuring the stability and safety of use.

[0032] like Figure 2 , 4 As shown in Figure 5, the first housing 4-1 has a first notch 9-1 formed below the integral structure, and the second housing 4-2 has a second notch 9-2 formed below the integral structure. When the first housing 4-1 and the second housing 4-2 are connected by the magnetic suction assembly 5, the first notch 9-1 and the second notch 9-2 are combined to form a finger buckle 9. The finger buckle 9 is used to facilitate the user's gripping of the bipolar electrocoagulation forceps during certain surgical procedures.

[0033] like Figure 3-4 As shown, the magnetic attraction assembly 5 between the first housing 4-1 and the second housing 4-2 includes 1-7 magnetic snap pairs. Each magnetic snap pair includes a first magnetic snap disposed on the inner side of the first housing 4-1 and a second magnetic snap disposed on the inner side of the second housing 4-2. The first magnetic snap and the second magnetic snap cooperate to ensure that the first housing 4-1 and the second housing 4-2 are detachably connected.

[0034] As one example, the inner side of the first housing 4-1 is provided with a first mounting groove 6 for mounting the first magnetic snap, and the inner side of the second housing 4-2 is provided with a second mounting groove for mounting the second magnetic snap. The positions of the first mounting groove 6 and the second mounting groove correspond, the shapes of the first mounting groove 6 and the second mounting groove correspond to the shapes of the first magnetic snap and the second magnetic snap, and the inner diameters of the first mounting groove 6 and the second mounting groove correspond to the outer diameters of the first magnetic snap and the second magnetic snap, to ensure that the first magnetic snap and the second magnetic snap can be securely engaged in the first mounting groove 6 and the second mounting groove. As an optimization of this example, when installing the first magnetic snap and the second magnetic snap, an appropriate amount of adhesive can be placed in the first mounting groove and the second mounting groove, or other reinforcement methods can be used.

[0035] As one example, at least two magnetic snap pairs are provided, and the magnetic snap pairs are divided into a first group of magnetic snap pairs 5-1 and a second group of magnetic snap pairs 5-2. The first group of magnetic snap pairs 5-1 is located above the integral structure, and the second group of magnetic snap pairs 5-2 is located below the integral structure. The first group of magnetic snap pairs 5-1 and the second group of magnetic snap pairs 5-2 can be uniformly arranged along the edges of the first housing 4-1 and the second housing 4-2.

[0036] As one example, the second set of magnetic snaps includes at least two pairs of magnetic snaps, and at least one pair of magnetic snaps is disposed between the snap 9 and the integral structure.

[0037] By adopting the above technical solution, the magnetic snaps are evenly arranged on the edge where the first housing 4-1 and the second housing 4-2 are connected, which can ensure that the first housing 4-1 and the second housing 4-2 are detachably connected, and also ensure the stability and firmness of the connection between the first housing 4-1 and the second housing 4-2.

[0038] like Figure 2 As shown, a first recess 10-1 is provided on the upper side of the first housing 4-1, and a second recess 10-2 is provided on the upper side of the second housing 4-2. The positions of the first recess 10-1 and the second recess 10-2 are corresponding. When the first housing 4-1 and the second housing 4-2 are joined together by a magnetic snap, the first recess 10-1 and the second recess 10-2 are joined together to form a groove 10.

[0039] By adopting the above technical solution, the operator of the instrument can easily disassemble the first housing 4-1 and the second housing 4-2 through the groove 10 provided on the upper side of the first housing 4-1 and the second housing 4-2.

[0040] Compared with existing technologies, the first housing 4-1 and the second housing 4-2 are detachably set, which makes it more convenient to maintain, clean and disinfect the instruments during use, ensuring the safety and effectiveness of instrument use. At the same time, the reusable instruments also reduce surgical costs and waste.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
