Description

Technical Field

[0001] The utility model relates to the technical field of monopolar electric knife smoke exhaust, in particular to a monopolar electric knife surgical smoke exhaust device. Background Art

[0002] The monopolar high-frequency electrosurgical unit is the most widely used electric current surgical system in current surgical procedures. It combines the functions of electrocuting and electrocoagulation, and can not only cut and separate tissues, but also play a good hemostatic role for bleeding in small and medium-sized blood vessels.

[0003] The existing patent document with the announcement number CN211962177U discloses a negative pressure suction electric knife with the function of absorbing smoke. Through the cooling mechanism, smoke collecting hood and smoke guide tube, etc., the smoke can be quickly absorbed during the electrocuting and electrocoagulation processes, and the temperature around the contact point of the electric knife can be quickly reduced, reducing the thermal damage of the surrounding tissues, which has a positive effect on reducing the patient's intraoperative injury and promoting the patient's rapid recovery after surgery, and effectively reducing the impact of smoke on the operator; at the same time, under the restriction of the smoke collecting hood, local bleeding is not easy to splash outside the surgical field operation area, effectively reducing the operator's contamination by blood stains, and can reduce the occupational exposure of medical workers to a certain extent during surgery on infectious patients.

[0004] Although the above-mentioned negative pressure suction electrosurgical knife with smoke absorption function can solve the corresponding technical problems, its micro vacuum pump is only tightly bonded to the outer wall of the knife pen, resulting in poor stability of the connection between the micro vacuum pump and the knife pen. It is very easy to be displaced or even loosened during use, which has a certain impact on the operation. For this reason, we propose a monopolar electrosurgical surgical smoke exhaust device.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 5 The present embodiment provides a smoke exhaust device for monopolar electrosurgical surgery, comprising: a smoke exhaust component 1 for absorbing smoke generated by a monopolar electrosurgical knife 4 when cutting tissue and performing electrocoagulation hemostasis, a connection component 2 for connection and fixing, and a cable sleeve 3 for preventing winding, wherein the connection component 2 and the cable sleeve 3 are sequentially arranged on the smoke exhaust component 1 from top to bottom; the connection component 2 comprises a screw sleeve 21 arranged on the smoke exhaust component 1, one side of the screw sleeve 21 is fixedly connected to a support 211, and the inner cavity of the support 211 is movably connected to a sleeve connector 22; the sleeve connector 22 comprises a first clamping plate 221 rotatably connected to the inner cavity of the support 211 through a rotating shaft, and one side of the first clamping plate 221 A second clamping plate 222 is rotatably connected via a rotating shaft, the first clamping plate 221 and the second clamping plate 222 are both arc-shaped structures, a placement cavity is formed between the first clamping plate 221 and the second clamping plate 222, a first side ear 223 is integrally formed on the side of the first clamping plate 221 away from the rotating shaft, a second side ear 224 is integrally formed on the side of the second clamping plate 222 away from the rotating shaft, a protrusion 225 is fixedly connected to the side of the first side ear 223 facing the second side ear 224, a through hole 226 is opened on the second side ear 224 for the protrusion 225 to pass through, and a positioning piece 227 for locking the through hole 226 is provided on the second side ear 224.

[0028] Among them, the smoke exhaust component 1 includes a cover shell 11 threadedly connected to the inner cavity of the screw sleeve 21, and a micro vacuum pump is installed in the inner cavity of the cover shell 11. The air inlet pipe and the exhaust pipe of the micro vacuum pump are both connected to a hose 12, and the top of the hose 12 located above is connected to a smoke hood 13. The cable sleeve 3 is sleeved on the hose 12 located below. When the micro vacuum pump is started, the smoke generated by the monopolar electric knife 4 during tissue cutting and electrocoagulation hemostasis is sucked in and discharged in turn by the smoke hood 13, the hose 12 and the micro vacuum pump, thereby reducing the impact of the smoke on the operator.

[0029] Among them, the cover shell 11 includes two shells 111 that are buckled together, and heat dissipation holes 112 are opened on the upper and lower parts of the surface of the shell 111. By adopting a split structure for the cover shell 11, the cover shell 11 can be opened to maintain or repair the micro vacuum pump inside it, and the heat dissipation holes 112 can ventilate and dissipate heat for the micro vacuum pump.

[0030] Among them, the positioning member 227 includes a block 2271 movably connected to the side of the second side ear 224 away from the first side ear 223, and a slot 2272 is opened on the side of the protrusion 225 facing the block 2271. One side of the block 2271 is stuck to the inner cavity of the slot 2272. When one side of the block 2271 is stuck to the inner cavity of the slot 2272, the protrusion 225 can be limited, effectively preventing the protrusion 225 from accidentally detaching from the inner cavity of the through hole 226 and causing the socket 22 to open.

[0031] Among them, a groove 2273 is opened on the side of the second side ear 224 close to the block 2271, and the inner cavity of the groove 2273 is fixedly connected with a guide column 2274, and the surface sliding sleeve of the guide column 2274 is provided with a sliding sleeve 2275, and one side of the sliding sleeve 2275 is fixedly connected with the block 2271. When the block 2271 moves, it can drive the sliding sleeve 2275 to slide in the inner cavity of the groove 2273 and the surface of the guide column 2274, so as to guide the block 2271, which can not only make the block 2271 move horizontally stably, but also facilitate the hole alignment operation of the block 2271 and the slot 2272.

[0032] Among them, a spring 2276 is provided on the surface of the guide column 2274, and the two ends of the spring 2276 are fixedly connected to the inner wall surface of the groove 2273 and one side of the sliding sleeve 2275 respectively. Through the elastic force of the spring 2276, the automatic reset function of the block 2271 can be realized, and the block 2271 can be stably stuck in the inner cavity of the slot 2272.

[0033] Among them, a slope is provided on the side of the block 2271 close to the through hole 226. The slope is used to allow the protrusion 225 to squeeze the slope when inserted into the inner cavity of the through hole 226, so that the block 2271 can gradually move away from the through hole 226, and there is no need to manually push the block 2271, thereby achieving the purpose of quickly closing the socket 22.

[0034] The inner wall surfaces of the first clamping plate 221 and the second clamping plate 222 are both glued with rubber pads 228, which can increase the friction between the first clamping plate 221, the second clamping plate 222 and the wire 45, thereby helping to improve the stability of the socket 22 buckled on the surface of the wire 45.

[0035] Among them, the monopolar electric knife 4 includes a handle 41, an electric knife rod 42 is installed on the top of the handle 41, an electric knife head 43 is installed on the top of the electric knife rod 42, the smoke hood 13 is sleeved on the surface of the electric knife rod 42, and the smoke hood 13 is covered at the lower end of the electric knife head 43, and the bottom of the handle 41 is fixedly connected with a connecting column 44, the connecting column 44 is located in the placement cavity, and a wire 45 is embedded in the bottom of the connecting column 44, and the wiring sleeve 3 is sleeved on the surface of the wire 45.

[0036] The working principle of the utility model is: by sleeve-fitting the smoke hood 13 on the surface of the electric knife rod 42, and making the screw sleeve 21 threadedly sleeved on the surface of the cover shell 11, and then shifting the block 2271, the block 2271 drives the sliding sleeve 2275 to slide in the inner cavity of the groove 2273 and the surface of the guide column 2274, and the spring 2276 is forced to shrink until the block 2271 is separated from the inner cavity of the slot 2272, and the protrusion 225 can be unlocked. At this time, the first clamping plate 221 and the second clamping plate 222 can be flipped open, so that the first clamping plate 221 drives the sliding sleeve 2275 to slide in the inner cavity of the groove 2273 and the surface of the guide column 2274. The first side ear 223 and the protrusion 225 move synchronously, so that the protrusion 225 is separated from the inner cavity of the through hole 226 until the socket 22 is fully opened; then the hose 12 located above is straightened, and the first clamping plate 221 and the second clamping plate 222 are buckled on the appropriate position of the surface of the connecting column 44 to complete the connection and fixing operation of the cover shell 11 and the connecting column 44; by starting the micro vacuum pump, the smoke generated by the electric knife head 43 during electrocuting and electrocoagulation is gathered by the smoke collecting hood 13 and sucked into the inner cavity of the hose 12 and finally discharged, thereby realizing the smoke exhaust operation.
