Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an ablation hemostasis electrode. Background Art

[0002] In various western medical surgeries, ablation hemostatic electrodes (commonly known as "electric knives") have been widely used, and have almost become an essential tool for surgical operations both at home and abroad. However, there is an unavoidable problem in the use of electric knives: smoke from burning tissues will be generated. More importantly, this smoke has been proven to be carcinogenic and will cause great harm to the health of the people participating in the operation.

[0003] There are also electric knives on the market that can absorb tissue smoke, see Chinese patent publication number CN115040234A, which sets a conventional smoke suction device in the handle, such as using an air pump to suck the smoke, thereby achieving the effect of completely removing the smoke. However, when the metal part of the electric knife is extended, the distance between the far end of the electric knife and the air inlet of the smoke suction device will increase, and its ability to absorb tissue smoke will be weakened. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the defect that the ability of attracting tissue smoke is weakened after the existing electric knife head is extended, so as to provide an ablation hemostasis electrode.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] Ablation hemostatic electrode, including:

[0007] Outer sheath;

[0008] A suction tube, wherein the suction tube is disposed in the outer sheath and a distal end thereof extends out from the outer sheath, the distal end of the suction tube is an open end, the interior of the suction tube is a cavity, and the cavity of the suction tube is connected to a negative pressure suction device;

[0009] The cutter head is integrally connected to the distal end of the side wall of the suction tube. The cutter head and the suction tube can move synchronously along the axial direction of the outer sheath. The cutter head and the suction tube are connected to the electric knife control device through a signal line.

[0010] To further optimize the technical solution, the cavity of the suction tube is flat.

[0011] To further optimize the technical solution, the cutter head is a needle-shaped cutter head, a rectangular sheet-shaped cutter head, or an arc-shaped sheet-shaped cutter head.

[0012] To further optimize the technical solution, the suction tube is a straight tube, and a lighting lamp is provided at the proximal end of the suction tube. The light emitted by the lighting lamp can be directly focused around the surgical field through the cavity of the suction tube.

[0013] To further optimize the technical solution, the outer sheath is divided into a first sleeve and a second sleeve from the distal end to the proximal end, and the inner diameter of the first sleeve is smaller than the inner diameter of the second sleeve; the blade head and the suction tube pass through the first sleeve and the second sleeve in sequence.

[0014] To further optimize the technical solution, a hose is connected to the side of the suction tube, the hose is connected to the negative pressure suction device, and the hose is located in the second sleeve.

[0015] Further optimizing the technical solution, the negative pressure suction device comprises:

[0016] An operating room negative pressure suction bottle, wherein the operating room negative pressure suction bottle is connected to the cavity of the suction tube;

[0017] An operating room hanging tower is provided with a negative pressure suction port, and the negative pressure suction port is connected to a negative pressure suction bottle in the operating room.

[0018] To further optimize the technical solution, a wheel suitable for adjusting the suction force is provided between the negative pressure suction port and the negative pressure suction bottle in the operating room.

[0019] The technical solution of the utility model has the following advantages:

[0020] 1. The ablation hemostasis electrode provided by the utility model makes the existing metal head of the electric knife into a form of a suction tube and a knife head integrated, the knife head and the suction tube move synchronously, and a cavity is set on the suction tube. Since the cavity is connected to the negative pressure suction device, the cavity has a negative pressure and can attract tissue smoke. Therefore, no matter how the knife head and the suction tube are extended, the distance between the distal end of the knife head and the open end of the suction tube does not change, and the tissue smoke can be effectively sucked away.

[0021] 2. The ablation hemostasis electrode provided by the utility model has a straight suction tube, and a lighting lamp is arranged at the proximal end of the suction tube. The light emitted by the lighting lamp can be directly directed to the distal end of the suction tube. Therefore, the light emitted by the lighting lamp can be directly focused around the surgical field through the cavity of the suction tube, thus completing the integration of the electric knife function.

[0022] 3. The ablation hemostatic electrode and negative pressure suction device provided by the utility model include an operating room negative pressure suction bottle and an operating room pendant, the cavity of the suction tube is connected to the operating room negative pressure suction bottle, and the operating room pendant has a negative pressure suction port, which is connected to the operating room negative pressure suction bottle. Therefore, the smoke generated during the operation can enter the operating room negative pressure suction bottle from the cavity of the suction tube, and finally be discharged into the atmosphere through the operating room pendant, which can avoid the smoke being directly discharged into the operating room.

[0023] 4. The ablation hemostasis electrode provided by the utility model has a wheel disposed between the negative pressure suction port and the negative pressure suction bottle in the operating room. The suction force can be adjusted by the wheel according to the smoke conditions during the operation, so as to better meet the needs of the operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] In various western medical surgeries, ablation hemostatic electrodes (commonly known as "electric knives") have been widely used, and have almost become an essential tool for surgical operations both at home and abroad. However, there is an unavoidable problem in the use of electric knives: smoke from burning tissues will be generated. More importantly, this smoke has been proven to be carcinogenic and will cause great harm to the health of the people participating in the operation.

[0041] There are also electric knives on the market that can absorb tissue smoke, see Chinese patent publication number CN115040234A, which sets a conventional smoke suction device in the handle, such as using an air pump to suck the smoke, thereby achieving the effect of completely removing the smoke. However, when the metal part of the electric knife is extended, the distance between the far end of the electric knife and the air inlet of the smoke suction device will increase, and its ability to absorb tissue smoke will be weakened.

[0042] To this end, the utility model designs an ablation hemostasis electrode that can powerfully absorb tissue smoke and has an integrated electric knife lamp. The suction tube and the knife head are arranged in one piece, so that the suction tube can move with the knife head, and the problem of weakened ability to absorb tissue smoke due to the extension of the knife head will not occur.

[0043] The specific embodiments of the present invention are described in detail below in conjunction with the ablation hemostasis electrode of the present invention.

[0044] like Figures 1 to 4As shown, this embodiment discloses an ablation hemostatic electrode, including an outer sheath 30, a suction tube 20 and a blade head 10. The outer sheath 30 is arranged on the periphery of the suction tube 20 to play a protective role, and the outer sheath 30 can be used as a handle. The suction tube 20 is arranged in the outer sheath 30 and its distal end extends from the outer sheath 30. The distal end of the suction tube 20 is an open end, and the interior of the suction tube 20 is a cavity. The cavity of the suction tube 20 is connected to a negative pressure suction device. The blade head 10 is integrally connected to the distal end of the side wall of the suction tube 20. The blade head 10 and the suction tube 20 can move synchronously along the axial direction of the outer sheath 30. The blade head 10 and the suction tube 20 are connected to the electric knife control device through a signal line.

[0045] The suction tube 20 and the cutter head 10 are both made of metal, and the electrosurgical knife control device controls the suction tube 20 and the cutter head 10 to discharge through a signal line.

[0046] The above-mentioned ablation hemostasis electrode makes the existing electric knife metal head into a form of a suction tube 20 and a knife head 10 integrated, the knife head 10 and the suction tube 20 move synchronously, and a cavity is set on the suction tube 20. Because the cavity is connected to the negative pressure suction device, the cavity has a negative pressure and can attract tissue smoke. Therefore, no matter how the knife head 10 and the suction tube 20 are extended, the distance between the distal end of the knife head 10 and the open end of the suction tube 20 does not change, and the tissue smoke can be effectively sucked away.

[0047] As a preferred embodiment, the cavity of the suction tube 20 is flat. The cavity of the suction tube 20 can also be set to other shapes, and its specific shape is not limited here.

[0048] In some embodiments, the cutter head 10 is a needle-shaped cutter head, a rectangular sheet-shaped cutter head, or an arc-shaped sheet-shaped cutter head. The specific shape of the cutter head 10 can be set according to actual needs.

[0049] In some embodiments, the suction tube 20 is a straight tube, and a lighting lamp 40 is disposed at the proximal end of the suction tube 20. The light emitted by the lighting lamp 40 can be directly directed to the distal end of the suction tube 20, so that the light emitted by the lighting lamp 40 can be directly focused around the surgical field through the cavity of the suction tube 20, thus completing the integration of the electric knife function. And because the lighting lamp 40 is disposed inside the proximal end of the suction tube 20, when the blade head 10 and the suction tube 20 move axially along the outer sheath 30, the lighting lamp 40 will also move with it, so the brightness of the light emitted from the distal end of the suction tube 20 will not change with the movement of the blade head 10 and the suction tube 20.

[0050] The lighting lamp 40 is connected to the electrosurgical knife control device through a lamp line 401, and the controlled end of the lighting lamp 40 is connected to the output end of the electrosurgical knife control device, and the lighting lamp 40 is controlled by the electrosurgical knife control device. The lighting lamp 40 is a high-efficiency LED lamp. In addition, the lighting lamp 40 can also use other types of lamps, and its specific type is not limited here.

[0051] In some embodiments, the outer sheath 30 is divided into a first sleeve 301 and a second sleeve 302 from the distal end to the proximal end, and the inner diameter of the first sleeve 301 is smaller than the inner diameter of the second sleeve 302; the blade head 10 and the suction tube 20 pass through the first sleeve 301 and the second sleeve 302 in turn.

[0052] A hose 50 is connected to the side of the suction tube 20 . The hose 50 is connected to the negative pressure suction device. The hose 50 is located in the second sleeve 302 . The hose 50 can be arranged in parallel with the suction tube 20 .

[0053] In some embodiments, the negative pressure suction device includes an operating room negative pressure suction bottle and an operating room pendant. The cavity of the suction tube 20 is connected to the negative pressure suction bottle in the operating room. The operating room pendant has a negative pressure suction port, which is connected to the negative pressure suction bottle in the operating room. The operating room pendant is an indispensable gas supply medical equipment in a modern operating room of a hospital, and is mainly used for terminal transfer of medical gases such as oxygen supply, suction, compressed air, and nitrogen in the operating room. Therefore, the smoke generated during the operation can enter the negative pressure suction bottle in the operating room from the cavity of the suction tube 20, and finally be discharged into the atmosphere through the operating room pendant, which can avoid the smoke being directly discharged into the operating room.

[0054] In some embodiments, a wheel is provided between the negative pressure suction port and the negative pressure suction bottle in the operating room. The wheel can be used to adjust the suction force according to the smoke condition during the operation, so as to better meet the needs of the operation. During the operation, when more smoke is generated, the wheel can be adjusted to increase the suction force at the distal end of the suction tube 20; when less smoke is generated, the wheel can be adjusted to reduce the suction force at the distal end of the suction tube 20.

[0055] The working process of the utility model is:

[0056] The electric knife control device controls the illuminating lamp 40 to start, and the illuminating lamp 40 emits bright light. The cutter head 10 is brought into contact with the skin tissue, and the electric knife control device controls the cutter head 10 to discharge, so that the cutter head 10 cuts the tissue.

[0057] The smoke generated by the cutting of the cutter head 10 is absorbed by the suction tube 20 integrally provided with the cutter head 10, transmitted to the hose 50 through the cavity of the suction tube 20, and then enters the negative pressure suction bottle in the operating room, and finally discharged into the atmosphere from the operating room pendant.

[0058] 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 from these are still within the scope of protection of the invention of the utility model.
