Description

Electrocoagulation knife smoke extraction pipe fixing device

Technical Field

The utility model relates to an electric coagulation sword auxiliary instrument especially indicates an electric coagulation sword smoke extraction pipe fixing device.

Background

In modern surgical operation, cutting is an indispensable operation, a steel blade is used for cutting conventionally until an electrocoagulation knife appears, and the electrocoagulation knife (hereinafter referred to as an electrotome) enables a knife head to gather energy through the conversion of electricity-heat energy, and heat coagulation is carried out on an action region in the cutting process, so that bleeding of small blood vessels does not exist in the cutting region, a clear operation visual field is kept, and the electrocoagulation knife is proved to be safe, and is widely applied to clinic at present.

However, because the electric knife is based on the principle of thermosetting, smoke is inevitably generated in the cutting and cauterizing process, the smoke affects the sight of the operator to different degrees, and a great deal of smoke is inhaled for a long time to cause adverse effects on the operator, so that doctors in clinic arrange an assistant to operate the smoke extraction pipe to synchronously suck smoke to keep the visual field clear. However, in a narrow operation space such as a pharyngeal cavity, a nasal cavity and the like or without an assistant, the two cannot be considered simultaneously, or the smoke extraction tube is very easy to interfere with the observation sight and normal cutting of the operation of the electrocoagulation knife, or a doctor cannot independently and effectively complete the operation.

Chinese patent application No. 202023063788.0 discloses an electrotome capable of preventing from generating abnormal red blood cells by electrotome smoke, as shown in fig. 1, the electrotome is mainly characterized in that a smoke suction pipe, a wound surface liquid protective film storage cavity and the like are arranged in a knife handle 1,

control buttons

3, 4, 5 and the like are arranged in the middle of the knife handle 1, a smoking through hole is arranged in a knife head part 2, and smoke is sprayed on a cutting wound and sucked away through the smoking through hole (6 in fig. 1 is a smoking joint, 7 is a cover added on the wound surface liquid protective film, and 8 is an electrotome power line). However, this technique is a need for improvements to the electrocoagulation knife itself and is not applicable to existing equipment of the consumer.

Similarly, as shown in fig. 2, the electric scalpel with smoke suction function of application No. 202121939352.5 is also provided with a hollow suction tube 201 and a circuit board 202 in the electric scalpel handle 20, which cannot be applied to the existing device. (FIG. 2 shows an electric knife head 21, a connection power cord 203, a smoke tube opening 2011, a fixed structure 2012, a tail connector 2013)

As shown in fig. 3, the attaching member 31 includes a first pipe clamp 33 for clamping the electric knife handle 32 and a second pipe clamp 35 for clamping the smoking pipe 34, and the first pipe clamp 33 is rotatably connected with a fixing block 36 between the second pipe clamp 35, so that the first pipe clamp 33 and the second pipe clamp 35 rotate relatively. However, the mode of fixing the electric knife by using the pipe clamp is not easy to fix, and is easy to slide or slip, and the first and

second pipe clamps

33 and 35 connected with each other are used, so that the distance between the smoke suction pipe 34 and the electric knife handle 32 is too large, which affects the hand feeling of the doctor holding the electric knife, and the rotatable structure between the two is adopted, which causes the mutual interference due to the relative movement during the operation, and is not good for the accurate operation, most importantly, the front end of the smoke suction pipe 34 is not fixed, and the distance between the smoke suction pipe head 36 and the second pipe clamp 35 is long, which causes the shake of the smoke suction pipe head and causes the interference with the electric knife and affects the operation, and certainly, if the smoke suction pipe head in fig. 3 is designed to be bent, the smoke suction pipe of the existing equipment also needs to be correspondingly modified.
