Description

Technical Field

[0001] The invention relates to the technical field of surgical medical equipment, and in particular to an ultrasonic high-frequency surgical knife. Background Art

[0002] With the development of modern medicine, many types of surgical equipment have been launched on the market as commodities, such as high-frequency electric knives, laser knives, microwave knives and other surgical knives. These high-tech scalpels have replaced traditional scalpels and are used in the removal of human diseased tissues and clinical surgical treatment. When working, they perform ultrasonic vibrations with a large amplitude and emit strong lasers or microwaves, which can significantly improve the quality of medical care and shorten the recovery time during clinical operations. In existing operations, when cutting soft tissues with general scalpels, a certain reciprocating pulling force is required, bleeding is high, the coagulation effect is poor, the cutting speed is slow, and the operation time is long. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the scalpel in the prior art, such as poor coagulation effect, slow cutting speed and long operation time, thereby providing an ultrasonic high-frequency scalpel with good coagulation effect, fast cutting speed and short operation time.

[0004] In order to solve the above technical problems, the present invention provides an ultrasonic high-frequency surgical knife, comprising:

[0005] A knife, provided at one end of the handle, comprising a first part and a second part connected in an openable and closed manner, wherein the first part is formed with two symmetrically distributed first discharge areas, the first discharge areas having tooth-shaped protrusions, and the second part is formed with two symmetrically distributed second discharge areas and an arc-shaped concave, the two first discharge areas being arranged correspondingly to the two second discharge areas;

[0006] an ultrasonic transducer, disposed at the other end of the handle, having a first end connected to a high-frequency power source and a second end connected to the second portion, wherein the second end is used to directly transmit a portion of the electric energy output by the high-frequency power source to the second portion of the tool;

[0007] The power transmission component is arranged in the handle and is electrically connected to the ultrasonic transducer, and is used to transmit another part of the power output by the high-frequency power supply to the first part of the tool. The first part and the second part of the tool discharge and work after receiving the corresponding power.

[0008] The ultrasonic high-frequency surgical knife, the power transmission component includes a conductive mechanism electrically connected to the conductive contact ring of the ultrasonic transducer, a bias mechanism electrically connected to the first part of the knife, and a conduction mechanism connecting the conductive mechanism and the bias mechanism.

[0009] In the ultrasonic high-frequency surgical knife, the conductive mechanism is a conductive sheet arranged in the handle.

[0010] In the ultrasonic high-frequency surgical knife, the biasing mechanism comprises a conductive spring connected to the first part of the knife and having a deformation direction perpendicular to the axial direction of the first part of the knife, and a conductive clamping ring connected between the conductive spring and the conductive mechanism.

[0011] In the ultrasonic high-frequency surgical knife, the conducting mechanism includes a conductive contact electrically connected to the conductive snap ring and a flexible circuit board for connecting the conductive contact and the conductive sheet.

[0012] The ultrasonic high-frequency surgical knife has two symmetrically distributed first discharge areas formed on the first part, and two symmetrically distributed second discharge areas formed on the second part, and the two first discharge areas are correspondingly arranged with the two second discharge areas.

[0013] In the ultrasonic high-frequency surgical knife, the first part of the knife is a clamp, the second part of the knife is a knife rod, and the outer surfaces of the clamp except the first discharge area and the knife rod except the second discharge area are coated with an insulating layer.

[0014] The ultrasonic high-frequency surgical knife also includes an outer tube sleeved outside the second part of the knife, one end of the second part of the knife extends out of the outer tube, and the first part of the knife is arranged at an end of the outer tube away from the ultrasonic transducer and is pivotally connected to the outer tube.

[0015] In the ultrasonic high-frequency surgical knife, the outer surface of the outer tube is coated with an insulating layer.

[0016] The technical solution of the present invention has the following advantages:

[0017] 1. The ultrasonic high-frequency surgical knife provided by the present invention has a part of the electric energy output by the high-frequency power supply that is supplied to the ultrasonic transducer to generate ultrasonic vibrations, a part of which is directly transmitted to the second part of the knife through the second end of the ultrasonic transducer, and the other part is transmitted to the first part of the knife through the electric energy transmission component arranged in the handle. The first part and the second part of the knife discharge and work after receiving the corresponding electric energy. The second part is formed with two symmetrically distributed second discharge areas, and the two first discharge areas are arranged correspondingly to the two second discharge areas. The second part is also formed with an arc-shaped concave. When the ultrasonic high-frequency surgical knife penetrates into the lesion, the concave structure of the arc-shaped concave ensures that its concave surface is separated from the body tissue, thereby maintaining a cavity between the body tissue and the concave surface, providing a path for blood circulation, reducing the local pressure caused by bleeding and increasing the movement resistance increased by the compression of the ultrasonic high-frequency surgical knife, thereby avoiding the ultrasonic high-frequency surgical knife from being wrapped and stuck by the tissue, and improving the cutting efficiency of the ultrasonic high-frequency surgical knife. In this way, not only ultrasonic cutting can be achieved, but also high-frequency electrocoagulation can be achieved, which improves the coagulation effect, increases the cutting speed, and reduces the doctor's operation time.

[0018] 2. The ultrasonic high-frequency surgical knife provided by the present invention has a biasing mechanism comprising a conductive spring connected to the first part of the knife and having a deformation direction perpendicular to the axial direction of the first part of the knife, and a conductive clamping ring connected between the conductive spring and the conductive mechanism. The electric energy generated by the high-frequency power supply is sequentially transmitted to the knife through the conductive clamping ring and the conductive spring, and the reliability of the electric energy transmission is ensured without affecting the rotation of the knife.

[0019] 3. The ultrasonic high-frequency scalpel provided by the present invention has two first discharge areas and two second discharge areas formed at the corresponding positions of the clamp and the knife rod respectively, which discharge after receiving the electric energy transmitted by the high-frequency power supply, thereby realizing the high-frequency bipolar coagulation function; and the outer surfaces of the clamp except the first discharge area and the knife rod except the second discharge area are coated with an insulating layer, which not only ensures that the electric energy will not damage the cut tissue during transmission and protects the human body, but also allows the discharge to proceed normally.

DETAILED DESCRIPTION

[0031] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] like Figure 1-2A specific embodiment of the ultrasonic high-frequency surgical knife shown in the figure comprises a cutter 2 and an ultrasonic transducer 3 respectively arranged at two ends of a handle 1. When installed, the ultrasonic transducer 3 is horizontally installed in the handle 1, and the cutter 2 is vertically installed in the handle 1 downward. The cutter 2 comprises a first part 21 and a second part 22 connected in an open-closed manner. The first part 21 is formed with two symmetrically distributed first discharge areas 211, and the first discharge areas have tooth-shaped protrusions. The second part 22 is formed with two symmetrically distributed second discharge areas 221 and an arc-shaped concave. The two first discharge areas 211 are arranged correspondingly to the two second discharge areas 221. The ultrasonic transducer 3 has a first end connected to a high-frequency power supply and a second end connected to the second part 22. The second end is used to directly transmit a portion of the electric energy output by the high-frequency power supply to the second part 22 of the cutter 2. The power transmission component provided in the handle 1 is electrically connected to the ultrasonic transducer 3, and is used to transmit another part of the power output by the high-frequency power supply to the first part 21 of the cutter 2. One part of the two parts of power carries a positive charge, and the other part carries a negative charge. The first part 21 and the second part 22 of the cutter 2 discharge and work after receiving the corresponding power. In this way, the ultrasonic high-frequency surgical knife of this embodiment can not only transmit ultrasonic energy and be used as an ultrasonic knife, but also transmit power and be used as a high-frequency electric knife. Of course, it can also be used as an ultrasonic knife and a high-frequency electric knife at the same time to meet different needs.

[0033] The power transmission assembly includes a conductive mechanism 4 electrically connected to the conductive contact ring of the ultrasonic transducer 3, a bias mechanism 5 electrically connected to the first portion 21 of the tool 2, and a conducting mechanism 6 connecting the conductive mechanism 4 and the bias mechanism 5. In this embodiment, the conductive mechanism 4 is a conductive sheet provided in the handle 1.

[0034] like Figure 3 and 4 As shown, the biasing mechanism 5 includes a conductive spring 51 connected to the first part 21 of the tool 2 and having a deformation direction perpendicular to the axial direction of the first part 21 of the tool 2, and a conductive snap ring 52 connected between the conductive spring 51 and the conductive mechanism 6. The conductive spring 51 is a plurality of conductive springs 51 distributed annularly on the side wall of the tool 2, and the conductive snap ring 52 is sleeved outside the plurality of conductive springs 51 to fix the ends of the conductive springs 51. The conductive mechanism 6 includes a conductive contact 61 electrically connected to the conductive snap ring 52 and a flexible circuit board for connecting the conductive contact 61 and the conductive sheet. The conductive contact 61 can also be annular, sleeved outside the conductive snap ring 52, and has an elastic contact electrically connected to the conductive snap ring 52, and the other end maintains an effective electrical connection with the conductive sheet through the flexible circuit board.

[0035] like Figure 5-7As shown, two symmetrically distributed first discharge areas 211 are formed on the first part 21, and two symmetrically distributed second discharge areas 221 are formed on the second part 22. The two first discharge areas 211 and the two second discharge areas 221 are arranged correspondingly, and are respectively located on both sides of the width direction of the first part 21 and the second part 22. Specifically, the first part 21 of the tool 2 is a clamp, and the second part 22 of the tool 2 is a tool bar, and the outer surfaces of the clamp except the first discharge area 211 and the tool bar except the second discharge area 221 are coated with an insulating layer 8. The insulating layer 8 is a DLC coating. During the production process, the entire outer surface of the clamp and the tool bar is first coated with the DLC coating, and then the coating at the first discharge area 211 and the second discharge area 221 is removed to ensure normal discharge and operation.

[0036] like Figure 1 and 8 As shown, it also includes an outer tube 7 sleeved outside the second part 22 of the cutter 2, one end of the second part 22 of the cutter 2 extends out of the outer tube 7, and the first part 21 of the cutter 2 is arranged at one end of the outer tube 7 away from the ultrasonic transducer 3, and is pivotally connected to the outer tube 7. The outer surface of the outer tube 7 is also coated with a DLC insulation layer 8.

[0037] As an alternative embodiment, the conductive contact ring of the ultrasonic transducer 3 can also be directly electrically connected to the clamp of the tool 2 through a flexible printed circuit board, as long as the electric energy output by the high-frequency power supply can be simultaneously transmitted to the clamp and the tool rod of the tool 2 through two paths and discharged.

[0038] As an alternative implementation, the conductive sheet 42 may also be ring-shaped.

[0039] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
