Description

Technical Field

[0001] The invention relates to the field of medical bipolar electrocoagulation forceps, in particular to a bipolar electrocoagulation forceps with a shearing function. Background Art

[0002] At present, bipolar electrocoagulation forceps are essential basic surgical instruments in neurosurgery. They can quickly cauterize and coagulate ruptured blood vessels to achieve the purpose of hemostasis. Especially when operating under a microscope, the requirements for hemostasis in the surgical field are more stringent, and the role of bipolar electrocoagulation forceps is even more irreplaceable. At the same time, in the process of opening up a surgical path to reach the lesion, it is necessary to electrocoagulate and cut off the tiny blood vessels blocking the field of vision. The usual practice is that the surgeon uses bipolar electrocoagulation forceps to stop bleeding, then replaces surgical scissors to cut the coagulated blood vessels, and then replaces the bipolar electrocoagulation forceps to continue the operation. In an operation, surgical instruments often need to be replaced repeatedly, which increases the workload and reduces efficiency. In addition, re-bleeding often occurs when using surgical scissors to cut blood vessels. At this time, if the bipolar electrocoagulation forceps cannot be replaced in time for hemostasis, the bleeding site is often lost due to excessive bleeding blocking the field of vision, resulting in difficulty in hemostasis, and even forced to perform blind electrocoagulation, which brings great trauma and risks to the operation.

[0003] Currently, some patents have been developed to solve this problem. Most of them use a retractable blade or retractable scissors to perform cutting after blood coagulation, but these blades or scissors still require an independent switch or button to control the extension and retraction, which is inconvenient during use and does not improve the convenience of surgery. Summary of the invention

[0004] In order to solve at least one of the above-mentioned technical problems, the technical solution adopted by the present invention is to provide a bipolar electrocoagulation forceps with a shearing function, which can not only perform effective electrocoagulation during surgery, but can also be conveniently transformed into scissors for shearing. It can be sheared with simple operations after electrocoagulation during the operation, which significantly improves the surgical efficiency and reduces the surgical risk.

[0005] In order to achieve at least one of the above purposes, the technical solution adopted by the present invention is:

[0006] The present invention provides a bipolar electrocoagulation forceps with a shearing function, comprising: a forceps handle and two forceps bodies, wherein the forceps bodies comprise forceps arms and forceps tips, one end of the two forceps arms is connected to the forceps handle, the front end of the forceps arms is connected to the forceps tips, the two forceps tips are composed of two half forceps tips, and the two half forceps tips can be relatively separated.

[0007] Furthermore, a supporting portion is disposed opposite to the two forceps arms.

[0008] Furthermore, the support portion is a groove structure on one tweezers arm and a convex structure on the other tweezers arm, and the groove structure and the convex structure can be interlocked together.

[0009] Furthermore, the two half tweezer tips are a first half tweezer tip and a second half tweezer tip, the first half tweezer tip is rigidly connected to the tweezer arm, and the second half tweezer tip is movably connected to the tweezer arm.

[0010] Furthermore, the second half of the forceps tip is connected to the forceps arm via a connecting spring.

[0011] Furthermore, the first half of the tip and the second half of the tip of one of the tweezers respectively correspond to the second half of the tip and the first half of the tip of another of the tweezers.

[0012] Furthermore, a boss structure is provided between the first half tweezer tip and the tweezer arm.

[0013] Furthermore, the boss structure protrudes toward the inner side of the forceps arm.

[0014] Furthermore, when the two tweezer tips interact with each other, the second half of the tweezer tip in the two tweezer tips is separated from the first half of the tweezer tip under the action of the boss structure.

[0015] Furthermore, the second half of the tweezers tip separated from the first half of the tweezers tip is reset under the action of the connecting spring sheet.

Please note that the embodiments described below are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. If no specific technology or conditions are specified in the embodiments, the technology or conditions described in the literature in the art or the product instructions shall be followed.

[0026] In the description of the present invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The bipolar electrocoagulation forceps with shearing function provided by the present invention will be described in detail below through specific embodiments:

[0029] like Figure 1-5As shown, the bipolar electrocoagulation forceps with shearing function provided by the present invention include a forceps handle 1 and two forceps bodies 2, the forceps body 2 includes forceps arms 3 and forceps tips 4, one end of the two forceps arms 3 is connected to the forceps handle 1, the front end of the forceps arm 3 is connected to the forceps tip 4, the two forceps tips 4 are composed of two half forceps tips, and the two half forceps tips are a first half forceps tip 5 and a second half forceps tip 6.

[0030] According to the present invention, a support portion 9 is relatively arranged between the two tweezer arms. The support portion 9 is a groove structure on one tweezer arm 3 and a convex structure on the other tweezer arm 3. When the two tweezer arms 3 are clamped together, the groove structure and the convex structure can be interlocked with each other to play a supporting and force-bearing role.

[0031] According to the present invention, the first half forceps tip 5 is rigidly connected to the forceps arm 3, and the second half forceps tip 6 is movably connected to the forceps arm 3. In particular, the second half forceps tip 6 is movably connected to the forceps arm 3 via a connecting spring 7, and the connecting spring 7 can withstand appropriate force without deformation. In a normal state, the first half forceps tip 5 and the second half forceps tip 6 are flush and together form a forceps tip 4, which can perform normal coagulation.

[0032] According to the present invention, the first half tip 5 and the second half tip 6 of one of the two tweezer tips 4 correspond to the second half tip 6 and the first half tip 5 of the other tweezer tip 4 respectively, and a boss structure 8 is also provided between the first half tip 5 and the tweezer arm 3, and the boss structure 8 protrudes toward the inner side of the tweezer arm 3; when cutting is required, the boss structure 8 on one tweezer tip 4 interacts with the second half tip 6 of the other tweezer tip 4, so that the second half tip 6 in the tweezer tip 4 is separated from the first half tip 5 under the action of force, forming a scissors shape for shearing.

[0033] During electrocoagulation, since the connecting spring piece 7 of the second half tweezer tip 6 can withstand appropriate pressure without deformation, the first half tweezer tip 5 and the second half tweezer tip 6 in the tweezer tip 4 are flush with each other and together form a tweezer tip 4, and the two tweezer tips 4 can be completely closed to perform normal coagulation. When cutting is required, since the two tweezer arms 3 have a certain elasticity, appropriate force is applied to the two tweezer arms 3, and the second half tweezer tips 6 in the two tweezer tips 4 are separated from the first half tweezer tips 5 that are rigidly connected by force, forming a scissors shape for cutting; when cutting is completed, the external force on the tweezer arms 3 is released, and the two second half tweezer tips 6 are automatically reset under the elastic force of the connecting spring piece 7, and are reunited with the fixedly connected first half tweezer tips 5 to form a tweezer tip 4.

[0034] Compared with the prior art, the bipolar electrocoagulation forceps with a cutting function provided by the present invention have the following beneficial effects: the bipolar electrocoagulation forceps with a cutting function provided by the present invention are electrocoagulation forceps with integrated coagulation and shearing functions, which can not only perform effective electrocoagulation during surgery, but can also be conveniently transformed into scissors for shearing.

[0035] The bipolar electrocoagulation forceps with shearing function provided by the present invention have an optimized design structure compared with the previous ones, are simple to operate, and have good stability, and have broad application prospects.

Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
