Description

Surgical puncture tool

This creation relates to surgical tools, particularly to a surgical puncture tool with a long service life.

When people need to undergo surgical treatment, medical staff often use some surgical cutting tools to perform surgical operations such as cutting the patient's body tissue. The scalpel is a surgical cutting tool widely used in surgery. Although it can effectively cut or cut body tissues, it cannot coagulate or stop bleeding of the cut body tissue.

With the development of science and technology, people's demand for medical quality has also been continuously improved. Therefore, in the technology of modern surgery, an electrosurgical knife has been developed. The electrosurgical knife cuts tissue while performing a surgical procedure and simultaneously cauterizes the tissue to coagulate or stop bleeding, wherein the electrical energy released by the electrosurgical knife causes the tissue to heat to cut the tissue and cauterize the blood vessel. This electrosurgical knife can quickly cut the skin and various soft tissues, precise cutting and cauterization and can greatly reduce surgical bleeding.

However, whether it is a traditional scalpel or an electrosurgical knife, it is made of metal. Since the scalpel or electrosurgical knife is used to cut the body tissue of the patient and is exposed to the body fluid and blood of the patient during use, the scalpel is used when the scalpel is used to cut the tissue during the operation. The metal material is easily dulled by wear and tear with human body tissues and chemical interactions with body fluids. A scalpel or an electrosurgical knife that becomes dull to a certain extent cannot be reused, thus causing a burden on the hospital's medical costs.

Therefore, the purpose of this creation is to provide a surgical puncture tool that can effectively extend the service life of the surgical puncture tool to reduce the burden on the hospital in medical costs.

In addition, the graphene layer can also improve the conductivity and thermal conductivity of the sharp end of the puncture tool to improve the cutting efficiency of the surgical puncture tool.

Embodiments of the present creation will be described below based on Figs. 1 to 2 . This description is not intended to limit the implementation of the present invention, but is one of the embodiments of the present invention.

As shown in FIGS. 1 and 2, a surgical stabbing tool 100 according to an embodiment of the present invention includes: a pricking tool 11 having a sharp-edged end 111 having a tapered shape The sharp end 111 is used to puncture the human tissue; and a graphene layer 12 is applied over the entire outer surface of the sharp end 111 of the pricking tool 11.

The graphene layer 12 has many excellent material properties including high mechanical strength, abrasion resistance, and corrosion resistance. Therefore, by coating the graphene layer 12 on the outer surface of the sharp end 111 of the puncturing tool 11, the effect of protecting the sharp end 111 of the puncturing tool 11 can be achieved to prolong the service life of the surgical puncturing tool 100. In addition, the graphene layer 12 has good heat conduction and electrical conductivity, and thus the graphene layer 12 can also improve the electrical conductivity and thermal conductivity of the sharp end 111 of the piercing tool 11. Thus, the pricking tool 11 can discharge and cut various tissues at a very low power to obtain and maintain a sharp sharpness of the sharp end 111. At the same time, the sharp end 111 with good sharpness can quickly cut the skin and various soft tissues, effectively reduce tissue necrosis, achieve precise cutting and cauterization, and greatly reduce surgical bleeding, so as to improve the cutting efficiency of the surgical pricking tool 100.

In detail, please refer to FIG. 1 and FIG. 2 simultaneously. This surgical stab tool 100 is a minimally invasive electrosurgical knife applied to surgical medical treatment. In this embodiment, the puncturing tool 11 is an active puncturing tool having an energizing end 112 for electrically connecting a power supply device (not shown). And between the sharp end 111 of the puncture tool 11 and the energizing end 112, an insulating member 13 is mounted on the puncture tool 11. Specifically, the pricking tool 11 must perform the work of stabbing the human tissue by the current supplied by the power supply device during use. This current is transmitted to the sharp end 111 of the pricking tool 11 via the energizing end 112, and the discharge is burned by the sharp end 111 to pierce the human tissue.

In the present embodiment, the piercing tool 11 is made of stainless steel, tungsten steel or other metal materials. However, it is not limited thereto, and other embodiments of the present invention may also be a hemostasis knife. Further, in the present embodiment, the graphene layer 12 is only coated on the surface of the sharp end 111 of the piercing tool 11. In other embodiments, in order to further improve the cutting efficiency of the surgical stabbing tool 100, the graphene layer 12 is coated on the energizing end 112 and extends over the sharp end 111. Therefore, the current supplied by the power supply device is directly transmitted from the graphene layer 12 on the energizing end 112 to the graphene layer 12 on the sharp end 111. Since the graphene layer 12 has excellent electrical conductivity, the discharge cauterization effect of the sharp end 111 can be improved to improve the cutting efficiency of the surgical stab tool 100.

Rather, the active puncturing tool may also be a compressed gas to assist the puncturing tool 11 in puncturing human tissue. It can be understood that the pricking tool 11 can also be a passive puncture tool, which means that no external source conditions such as applying current are needed on the pricking tool 11, and only relying on the puncture tool 11 by the medical staff alone. Shili can be used to carry out the work of stabbing human tissue. In other embodiments of the present invention, the passive pricking tool can be an injection needle, a surgical probe, a file, a bone knife, or a scalpel.

Referring to FIG. 1 and FIG. 2 simultaneously, in particular, the graphene layer 12 is coated on the sharp end 111 of the pricking tool 11 by physical vapor deposition (PVD) or chemical vapor deposition (CVD). The overall outer surface, and the thickness of the graphene layer 12 is between 0.35 nm and 200 nm. In the present embodiment, in order to achieve optimum wear resistance and conductivity effects under cost considerations, the optimum thickness of the graphene layer 12 is between 60 nm and 100 nm. In addition, in other embodiments, in order to reduce the stress of the bonding interface between the puncture tool 11 and the graphene layer 12, an interposer is disposed between the sharp end 111 of the pricking tool 11 and the graphene layer 12 (not Painted). This interposer is first applied over the entire outer surface of the sharp end 111 of the pricking tool 11, and then the graphene layer 22 is applied over the interposer. The coefficient of thermal expansion of the interposer is between the coefficient of thermal expansion of the puncture tool 11 and the coefficient of thermal expansion of the graphene layer 12.

Referring to FIG. 3 and FIG. 4 simultaneously, according to another embodiment of the present invention, a surgical stabbing tool 200 is applied to a surgical medical electrosurgical electrosurgical knife. The surgical stab tool 200 includes: a pricking tool 21 having a blade-shaped sharp end 211 for piercing human tissue; and a graphene layer 22 coated with The sharp end 211 of the pricking tool 21. In detail, the difference between the surgical stab tool 200 and the surgical stab tool 100 is mainly that the outer shape of the sharp end 211 of the pricking tool 21 is different from the outer shape of the sharp end 111 of the pricking tool 11. Specifically, the sharp end 211 of the pricking tool 21 is in the shape of a blade, and the sharp end 111 of the pricking tool 11 has a pointed shape. Although the shape of the sharp end 211 is different from that of the sharp end 111, both the sharp end 211 and the sharp end 111 have sharp edges for piercing human tissue. In other words, the present creation does not limit the shape of the sharp end of the piercing tool, as long as the sharp end has a sharp edge for piercing human tissue.

With the above structure, the graphene layer is coated on the outer surface of the sharp end of the piercing tool, and the effect of protecting the sharp end of the piercing tool can be achieved. This graphene layer can prevent the sharp end from becoming blunt due to contact wear with body tissues or body fluid blood. Therefore, the graphene layer can effectively extend the service life of the surgical puncture tool to reduce the burden on the hospital in medical costs. In addition, the graphene layer with good thermal conductivity and conductivity can also improve the conductivity and thermal conductivity of the sharp end, enabling medical personnel to complete surgical operations more quickly.
