Description

Technical Field

[0001] This application relates to the technical field of medical devices, and specifically relates to an attracting electrocoagulation forceps. Background Art

[0002] An electrocoagulation forceps is a pair of forceps used for clamping and electrocoagulation surgical operations. It is usually used in surgeries that require electrocautery coagulation, such as ophthalmic surgeries, otolaryngology surgeries, interventional radiology, etc. By using high-frequency electrical signals to heat the metal wire in the forceps, a high temperature is generated at the tip of the forceps to clamp and coagulate tissues. During the surgery, it can effectively control bleeding and reduce surgical risks. In fields such as dermatology, the electrocoagulation forceps can also be used to cut and aspirate soft skin tissue fluid. For existing electrocoagulation forceps with an attracting function, an attracting channel is usually opened inside the forceps rod, and external negative pressure equipment is used to suck away blood, tissue fluid, perfusion fluid, etc. However, since the attracting channel is extremely small, it is inconvenient to clean. Moreover, the head of the forceps is usually inclined, which causes the attracting channel to face one side. When attracting is required, the forceps have to be rotated, and other tissues may be poked during the angle adjustment, resulting in secondary damage to the wound. Utility Model Content

[0003] The purpose of this application is to provide an attracting electrocoagulation forceps, which solves the problems mentioned in the background art, namely, due to the extremely small attracting channel, it is inconvenient to clean, and the head of the forceps is usually inclined, which causes the attracting channel to face one side. When attracting is required, the forceps have to be rotated, and other tissues may be poked during the angle adjustment, resulting in secondary damage to the wound.

[0004] To achieve the above purpose, this application provides the following technical solution: An attracting electrocoagulation forceps includes an electrode tail seat, an inner insertion rod, a movable forceps head, and a pressing bolt. Two forceps rods are fixedly connected to the side wall of the electrode tail seat. The other ends of the forceps rods are respectively fixedly connected with a hollow rod and an electrocoagulation rod. A rotating groove is opened at the end of the hollow rod far from the forceps rod. The movable forceps head is rotatably connected to the end of the hollow rod far from the forceps rod through the rotating groove. The inner insertion rod is movably inserted into the hollow rod through the end of the hollow rod close to the forceps rod, and a discharge channel is penetrated and opened inside the inner insertion rod. An attracting channel is penetrated and opened inside the movable forceps head. An extension channel is opened on the surface of the end of the movable forceps head facing the inside of the hollow rod. Limiting blocks are fixedly connected to the surfaces of the movable forceps head on both sides of the extension channel. Limiting grooves with corresponding dimensions are opened on the surface of the left end of the inner insertion rod horizontally facing the limiting blocks. An outer cap is fixedly connected to the outer surface edge of the right end of the inner insertion rod, and a pressing bolt is threadedly connected through the outer surface of the outer cap.

[0005] In this technical solution, metal wires are provided inside the electrocoagulation rod and the fixed tweezers head, which are used to coagulate tissue, efficiently stop bleeding and destroy capillaries after being energized, while the hollow rod and the movable tweezers head are used to attract tissue fluid, soft tissue and perfusion fluid, etc. The fixed tweezers head and the movable tweezers head cooperate with each other to clamp tissue, and the hollow rod and the inner rod can facilitate the cleaning of the instrument. After the inner rod is inserted into the hollow rod, the suction channel, the extension channel, the discharge channel and the external joint will be connected, and the negative pressure suction device can be connected to the external joint, and the suction operation can be started through the suction channel on the surface of the movable tweezers head. After the suction is completed, the inner rod can be pulled out of the hollow rod, and the hollow rod and the inner rod can be cleaned separately, thereby The problem of inconvenient cleaning due to the small internal space of the tweezers is avoided. At the same time, the direction of the suction channel can be easily adjusted through the limit block, the limit groove, the outer cap and the extrusion bolt. After the inner rod is fully inserted, the limit block will be inserted into the limit groove. At this time, the extrusion bolt can be turned to drive the inner rod and the movable tweezers head to rotate, so that the suction channel is rotated to a suitable suction angle, so there is no need to rotate the entire electrocoagulation tweezers, avoiding secondary damage caused by touching the wound due to excessive movement, thereby improving the convenience and practicality of the instrument. After the rotation direction, tighten the extrusion bolt, the extrusion bolt will contact the anti-slip layer on the surface of the hollow rod, thereby squeezing and fixing the inner rod, thereby maintaining the stability of the movable tweezers head in front.

[0006] As an optional solution of the technical solution of the present application, the diameter of the extension channel is consistent with the inner diameter of the discharge channel.

[0007] As an optional solution of the technical solution of the present application, an external joint is opened in the center of the right end of the inner insertion rod, and the external joint is connected to the discharge channel.

[0008] As an optional solution of the technical solution of the present application, one end of the electrocoagulation rod away from the tweezers rod is fixedly connected to a fixed tweezers head.

[0009] As an optional solution of the technical solution of the present application, the extension channel is connected to the suction channel, and the inner diameters of the extension channel and the suction channel are consistent.

[0010] As an optional solution of the technical solution of the present application, an anti-slip layer is provided on the edge of the outer surface of the left end of the hollow rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The present application can facilitate the cleaning of the instrument through the hollow rod and the inner rod. After the inner rod is inserted into the hollow rod, the suction channel, the extension channel, the discharge channel and the external joint will be connected. After the negative pressure suction device is connected to the external joint, the suction operation can be started through the suction channel on the surface of the movable tweezers head. After the suction is completed, the inner rod can be pulled out of the hollow rod, and the hollow rod and the inner rod can be cleaned separately, thereby avoiding the problem of inconvenient cleaning due to the small internal space of the tweezers.

[0013] 2. The present application can conveniently adjust the direction of the suction channel through the limit block, limit groove, outer cap and extrusion bolt. After the inner rod is fully inserted, the limit block will be inserted into the limit groove. At this time, by turning the extrusion bolt, the inner rod and the movable tweezers head can be driven to rotate, so that the suction channel can be rotated to a suitable suction angle, thereby eliminating the need to rotate the entire electrocoagulation tweezers, avoiding secondary damage caused by touching the wound due to excessive movement, thereby improving the convenience and practicality of the instrument.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, they are further explained below in conjunction with specific implementation methods.

[0021] like Figure 1As shown in the figure, an attracting electrocoagulation forceps includes an electrode tail seat 1, an inner inserting rod 5, a movable forceps head 4, and a pressing bolt 101. Two forceps rods 2 are fixedly connected to the side wall of the electrode tail seat 1. The other ends of the forceps rods 2 are respectively fixedly connected with a hollow rod 3 and an electrocoagulation rod 301. The end of the electrocoagulation rod 301 away from the forceps rod 2 is fixedly connected with a fixed forceps head 401. The fixed forceps head 401 and the electrocoagulation rod 301 can generate heat by accessing an electric current, which is convenient for coagulating tissues and stopping bleeding, etc.

[0022] As Figure 2 shown, the diameter of the extension channel 12 is the same as the inner diameter of the discharge channel 501. After the inner inserting rod 5 is inserted, the extension channel 12 will be inserted into the discharge channel 501 and fit tightly, which can avoid air leakage. And there is a damping effect when they slide relative to each other, which can play a role in partial limiting.

[0023] As Figure 2 and Figure 3 shown, a rotating groove 6 is opened at the end of the hollow rod 3 away from the forceps rod 2. The movable forceps head 4 is rotatably connected to the end of the hollow rod 3 away from the forceps rod 2 through the rotating groove 6. The inner inserting rod 5 is movably inserted into the hollow rod 3 through the end of the hollow rod 3 close to the forceps rod 2. And a discharge channel 501 is penetrated and opened on the inner side of the inner inserting rod 5. An attracting channel 11 is penetrated and opened on the inner side of the movable forceps head 4. An extension channel 12 is opened on the surface of the end of the movable forceps head 4 facing the inner side of the hollow rod 3. The extension channel 12 is communicated with the attracting channel 11, and the inner diameters of the extension channel 12 and the attracting channel 11 are the same.

[0024] As Figure 3 shown, limiting blocks 7 are fixedly connected to the surfaces of the movable forceps head 4 on both the upper and lower sides of the extension channel 12. Limiting grooves 8 corresponding in size are opened on the surface of the left end of the inner inserting rod 5 facing the horizontal direction of the limiting blocks 7. The limiting grooves 8 can allow the limiting blocks 7 to slide in completely, so that the inner inserting rod 5 can drive the movable forceps head 4 to rotate together.

[0025] As Figure 1 and Figure 4 shown, an outer cap 10 is fixedly connected to the outer surface edge of the right end of the inner inserting rod 5. A pressing bolt 101 is threadedly connected through the outer surface of the outer cap 10. The pressing bolt 101 can be used as a lever for adjusting the angle and can also play a role in limiting and fixing the inner inserting rod 5 after being tightened.

[0026] As Figure 4 shown, an outer joint 9 is opened at the center of the right end of the inner inserting rod 5. The outer joint 9 is communicated with the discharge channel 501. The outer joint 9 is used to connect a negative pressure suction device, so that the attracting channel 11 can perform suction operations. An anti-slip layer 13 is opened on the outer surface edge of the left end of the hollow rod 3. The anti-slip layer 13 can increase the friction force after the pressing bolt 101 is tightened and contacted, so that the inner inserting rod 5 can be more stable.

[0027] In actual use, the electrocoagulation rod 301 and the fixed tweezers head 401 are provided with metal wires inside, which are used to coagulate tissue, efficiently stop bleeding and destroy capillaries after being energized, while the hollow rod 3 and the movable tweezers head 4 are used to attract tissue fluid, soft tissue and perfusion fluid, etc. The fixed tweezers head 401 and the movable tweezers head 4 cooperate with each other to clamp the tissue. After the inserted rod 5 is inserted into the hollow rod 3, the suction channel 11, the extension channel 12, the discharge channel 501 and the external joint 9 will be connected. After the negative pressure suction device is connected to the external joint 9, the suction operation can be started through the suction channel 11 on the surface of the movable tweezers head 4. After the suction is completed, the inserted rod 5 can be pulled out from the hollow rod 3, and the hollow rod 3 and the inner The cleaning of the insertion rod 5 avoids the problem of inconvenient cleaning due to the small internal space of the tweezers. After the inner insertion rod 5 is fully inserted, the limit block 7 will be inserted into the limit groove 8. At this time, the extrusion bolt 101 is turned to drive the inner insertion rod 5 and the movable tweezers head 4 to rotate, so that the suction channel 11 is rotated to a suitable suction angle, so there is no need to rotate the entire electrocoagulation tweezers, avoiding secondary damage caused by touching the wound due to excessive movement, thereby improving the convenience and practicality of the instrument. After the rotation direction, tighten the extrusion bolt 101, and the extrusion bolt 101 will contact the anti-slip layer 13 on the surface of the hollow rod 3, thereby squeezing and fixing the inner insertion rod 5, thereby maintaining the stability of the movable tweezers head 4 in front.
