The working electrode is used for performing cutting ablation treatment or coagulation treatment on the target tissue, and is electrically connected with the other lead wire 21.

It should be noted that the holding electrode 30 serves as a return electrode, a wire connected to the return end, and the working electrode serves as an output electrode, a wire connected to the output end. The holding electrode 30 may be any of various electrode structures capable of performing a fixing and holding function, such as a clamp, a hook, a picking tool, etc., and is not limited herein; the working electrode may be of various electrode structures capable of performing a cutting function, such as a knife shape, a saw shape, a pincer shape, etc., and is not limited thereto. In addition, the target tissue may be various kinds of human or animal tissues, and this embodiment will be described hereinafter with soft tissues as an example.

In operation, the separated bipolar cutting tool described above connects the power plug 10 to an external power source, clamps and fixes the target tissue by the holding electrode 30, and performs cutting ablation treatment or coagulation treatment on the target tissue by the working electrode. On the one hand, the holding electrode 30 and the working electrode are respectively connected with the power plug 10 through the lead 21 and are separated, so that the respective operations of the holding electrode 30 and the working electrode are relatively flexible, and the respective operations are completed in a certain space, so that the problem that in the prior art, a large block of tissues are difficult to cut and separate due to the fact that two poles are fixed together and the distance is small is avoided, the holding electrode 30 and the soft tissues are clamped and fixed, the stability is good, the operation is convenient, the holding electrode is equivalent to the function of a neutral electrode plate, and the problem that in the prior art, the monopolar electrode is accidentally scalded due to the fact that the neutral electrode plate is improperly used can be avoided; on the other hand, the cutter electrodes are combined in a variety, so that surgical application in different scenes can be realized, the time for replacing different cutters can be further reduced, the surgical time is shortened, convenience is brought to doctors, and meanwhile, the pain of patients is relieved; in addition, the separated bipolar cutter has multiple functions, so that the cost is reduced relative to the reduction of cutter materials.

Referring to fig. 1 and fig. 2, fig. 2 is a schematic structural diagram of a clamping portion 311 of a split bipolar tool according to an embodiment of the utility model. In one embodiment, the holding electrode 30 includes two conductive clamping arms 31 electrically connected to one of the wires 21, one ends of the two conductive clamping arms 31 are connected to each other, and the other ends of the two conductive clamping arms 31 are free ends and are provided with clamping portions 311. Thus, when the clamping portions 311 of the two conductive clamping arms 31 are close to each other, the soft tissue can be clamped, and a loop can be formed while the soft tissue is clamped. When the surgical operation is completed, the clamping portions 311 of the two conductive clamping arms 31 are separated, releasing the soft tissue. In addition, the structure of the holding electrode 30 is similar to forceps, so that the operation can be facilitated and the working efficiency is high.

It should be noted that, the "clamping portion 311" may be a part of the "conductive clamping arm 31", that is, the "clamping portion 311" and the "other part of the conductive clamping arm 31" are integrally formed; or a separate component which is separable from the other part of the conductive clamping arm 31, that is, the clamping part 311 can be manufactured independently and then combined with the other part of the conductive clamping arm 31 into a whole.

In one embodiment, the ends of the two conductive clamping arms 31 are connected by a resilient member (not shown). Thus, the elastic member plays a role of elastic reset, and after the two conductive clamping arms 31 are loosened, the distance between the two clamping portions 311 can be restored to the initial position, so that the use convenience can be improved. Wherein, alternatively, the two conductive clamping arms 31 are integrally connected with the elastic piece, and the metal piece is similar to forceps and has elastic force for restoring the original shape, and is integrally formed in a manufacturing way including but not limited to forging, die casting and the like.

Of course, in another embodiment, the holding electrode 30 further includes a connection base 32, and the connection base 32 is, for example, an elastic base. The ends of the conductive clamping arms 31 are connected with the connecting base 32, and one of the wires 21 also penetrates through the connecting base 32 to be electrically connected with the two conductive clamping arms 31. In this way, the two conductive clamping arms 31 can be driven to restore to the initial position under the elastic force of the connecting seat 32. Furthermore, the two conductive clamping arms 31 can be manufactured separately from each other and assembled to the connection base 32, and the two conductive clamping arms 31 and one of the wires 21 can be assembled together by the connection base 32.

In one embodiment, the conductive clamping arm 31 is provided with a gripping portion, and an insulating layer (not shown) is provided on an outer wall of the gripping portion. Thus, the insulating layer can prevent the holding electrode 30 from being conducted with the holding electrode 30 when the holding electrode 30 is held by hand, i.e. prevent the holding electrode 30 from acting on the hand.

Referring to fig. 1 and 2, in one embodiment, at least one wall surface of the two clamping portions 311 opposite to each other is provided with an anti-slip structure 3111. The anti-slip structure 3111 includes, but is not limited to, anti-slip bumps, anti-slip grooves, or anti-slip textures. In this way, the two clamping portions 311 have the anti-slip structure 3111, so that slipping phenomenon can be avoided during the process of clamping soft tissues, and soft tissues can be stably clamped and fixed.

In one embodiment, the clamping portion 311 includes, but is not limited to, a disk shape having a regular shape and an irregular shape in cross section, such as a circular shape, an elliptical shape, or a polygonal shape. Wherein polygons include, but are not limited to, triangles, quadrilaterals, pentagons, and the like. In this embodiment, the clamping portion 311 is, for example, a disc shape, which has no corner, and can reduce the irritation damage to the soft tissue during the contact with the soft tissue.

Referring to fig. 1 and 3, fig. 3 is a schematic structural diagram of a conductive portion 411 of a split bipolar tool according to an embodiment of the utility model. In one embodiment, the working electrode includes a conductive body 41 electrically connected to the other wire 21, and the head of the conductive body 41 is provided with a flat conductive portion 411. Thus, the flat conductive portion 411 has a small thickness and a large width, just like a blade. In operation, the holding electrode 30 clamps the soft tissue, and the conductive portion 411 of the working electrode acts on the soft tissue to cut and coagulate the soft tissue. Specifically, when a wall surface of the conductive portion 411 having a small thickness dimension (i.e., a plate edge of a conductive plate hereinafter) is brought into contact with soft tissue, energy is concentrated due to a small contact area, and a cutting function is exerted at this time; when a wall surface having a large width of the conductive portion 411 (hereinafter, a plate surface of a conductive plate) is brought into contact with soft tissue, a coagulation function can be exerted at this time due to a large contact area.

Alternatively, the conductive portion 411 is specifically, for example, a conductive plate. The two opposite plate surfaces of the conductive plate are regular-shaped surfaces or irregular-shaped surfaces such as planes, arc-shaped surfaces and the like, and can be flexibly selected and arranged according to actual requirements. The two opposing plate surfaces of the conductive plate are disposed parallel to each other, for example, and may be not parallel to each other. In addition, the shape of the two opposite faces of the conductive plate may be uniform, i.e. both are planar, for example, but may also be different, i.e. one of the faces is planar, for example, and the other opposite face is curved, for example, curved.

In one embodiment, when the plate surface of the conductive plate is disposed as a plane, the plate surface of the conductive plate is, for example, circular, elliptical, or polygonal. Polygons include triangles, quadrilaterals, pentagons, and the like. In this embodiment, the plate surface of the conductive plate is rectangular.

In one embodiment, the thickness of conductive portion 411 is defined as D, which is 0.1mm-5mm. Thus, the thickness D of the conductive portion 411 is set to be relatively suitable, on the one hand, the thickness D is small enough to ensure a relatively good cutting effect on the soft tissue; on the other hand, the thickness D is large enough to ensure that the strength of the conductive portion 411 is sufficient, that is, not too small to cause deformation and bending when subjected to a force, and thus cannot play a cutting role.

In addition, it is understood that the thickness D may be any other value than 0.1mm-5mm according to practical requirements, and how to select the thickness D is not limited herein.

In one embodiment, the width of conductive portion 411 is defined as W, which includes, but is not limited to, 0.2mm-20mm. Therefore, the width W is properly set, on one hand, the size of the width W is large enough to ensure that the width W can play a normal coagulation function when the width W is contacted with soft tissues, and on the other hand, the size of the width W is not too large to cause the coagulation function to be weakened.

Referring to fig. 1, in one embodiment, the working electrode further includes a grip handle 42. The grip handle 42 is an insulator, the conductive body 41 is inserted into the grip handle 42, and the conductive portion 411 is located outside the grip handle 42. Therefore, the conduction between the working electrode and the working electrode when the working electrode is held can be avoided, namely the working electrode is prevented from acting on the hand.

Referring to fig. 1, in one embodiment, the working electrode further includes a control switch 43 disposed on the grip handle 42. The control switch 43 is used to control the conductive body 41 to be connected to or disconnected from the conductive wire 21. Thus, the operation can be conveniently performed, and the practicability of the separated bipolar cutter is enhanced.

In one embodiment, the exposed area of the clamping portion 311 holding the electrode 30 is substantially larger than the exposed area of the conductive portion 411 of the working electrode. In this way, the soft tissue is less damaged by the stimulus when the clamping portion 311 of the holding electrode 30 and the soft tissue are clamped and fixed, and the conductive effect is mainly exerted to form a loop. The exposed area of the conductive portion 411 of the working electrode is selected and set mainly for performing the cutting and separating functions and the coagulation function.

In one embodiment, the shape of the holding electrode 30 and the working electrode are provided with various different shapes according to the use scenario. That is, the conductive clamp arm 31 includes, but is not limited to, being arranged in a straight line as shown in fig. 1, and can be flexibly adjusted to other shapes, such as being arranged in an arc shape, an L shape, an S shape, a W shape, and the like, for example, according to actual needs. Likewise, the conductive body 41 includes, but is not limited to, being arranged in a straight line shape as shown in fig. 1, and can be flexibly adjusted to other shapes, such as being arranged in various shapes of arc shape, L shape, S shape, W shape, and the like, according to actual needs.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
