Description

Technical Field

[0001] This invention relates to medical surgical instruments, specifically an electric surgical scissor head with a blade on one side and an insulating material on the back, primarily but not limited to use in tissue transection and coagulation procedures during minimally invasive surgery. Background Technology

[0002] Surgical scissor tips are commonly used surgical instruments. They utilize the principle that the high-frequency current from the scissors can rapidly coagulate and stop bleeding in contact with tissue, achieving rapid hemostasis while simultaneously severing tissue. To ensure the conductivity of the scissors, both blades of currently used scissor tips are made of metal. However, due to the complexity of the human body, during actual surgical procedures, while the high-frequency current is used to coagulate the tissue to be severed, the scissor tip, including the blade back, is made of metal. If the back of the scissors comes into contact with other human tissue structures, it can cause electrical burns, leading to surgical collateral damage. Therefore, developing an electric scissor that facilitates surgical operation while avoiding collateral damage to other human tissue structures during operation is a technical problem that needs to be seriously addressed. Summary of the Invention

[0003] To address the aforementioned deficiencies of existing technologies, this invention provides a surgical electric scissor tip with one blade having an insulating back side. The surgical electric scissor tip has a structure similar to conventional surgical electric scissors, with the blade body consisting of a shaft and two blades. However, while conventional electric scissor tips use conductive metal for both blades, this invention changes the structure of one blade from a conventional conductive all-metal blade to one where the back side of one blade is made of insulating material, or even entirely of insulating material such as ceramic or diamond. This ensures that one side of the electric scissor tip is non-conductive, facilitating electrocoagulation and tissue cutting during surgical procedures. The non-conductive nature of the insulating back side prevents electrical burns to other human tissues in contact with the scissor tip, reducing surgical complications. This invention features a simple structure, simple manufacturing process, and good performance. It can be conveniently used in various surgical procedures using electric scissors, allowing surgeons to perform electrocoagulation and tissue cutting while minimizing surgical complications, resulting in significant economic and social benefits.

[0004] Figure 1 This is a simplified structural diagram of a surgical electric scissor head with one blade and an insulating material on the back, as described in this invention.

[0005] Figure 2 This is a schematic diagram of the mechanism in which the back side of one of the blades in a specific embodiment of the present invention uses insulating material.

[0006] Figure 3 This is a schematic diagram of a mechanism in a specific embodiment of the present invention, in which one of the blades is entirely made of insulating material. Detailed Implementation

[0007] The specific embodiments of the present invention will be described in detail below with reference to Figures 1, 2, and 3.

[0008] Depend on Figure 1 As shown, the surgical electric scissors head body of the present invention, with one side blade made of insulating material and the back side of the blade being insulating material, consists of a shaft (1) and two blades (2); Figure 2 As shown, the structure of one of the blades in this invention is changed from a conventional conductive all-metal sheet to an insulating material (4) used for the blade's shearing back (3) portion; Figure 3 As shown, the structure of one of the blades in this invention is changed from a conventional conductive all-metal sheet to a blade in which one of the blades is made entirely of insulating material (5).

[0009] When using this invention, as Figure 2 , 3 As shown, during surgical procedures involving electrocoagulation and tissue cutting using electric scissors, if there are important human tissues or structures nearby that need protection to avoid secondary damage, the operator can use the side of the electric scissor tip with insulation to approach the tissue structure that needs protection. By utilizing the non-conductive properties of the insulation material, the metal structure of the electric scissors can be isolated from the surrounding tissue structure, thus preventing secondary damage from electric burns.

[0010] This invention has a simple structure, simple manufacturing process, is easy to use, and has good effects. It can be conveniently used in various surgical operations that use electric scissors, making it easier for surgeons to use electric scissors to electrocoagulate and cut tissue while avoiding surgical side effects, resulting in significant economic and social benefits.
