A medical high-frequency electrosurgical unit

Abstract

A high-frequency electrosurgical unit for medical use includes an execution unit, a control unit, and a first suction tube. The execution unit has a blade body and a blade tip. The front end of the first suction tube is configured as an air inlet. At least one mounting portion is obliquely arranged on the first suction tube, and the mounting portion has a cavity. In this invention, by connecting the front end of the cavity to the air inlet, the execution unit is inserted from the rear end of the cavity, allowing the front end of the blade tip to extend exposed to the outside of the air inlet. This brings the air inlet closer to the blade tip, enabling the smoke to be drawn into the first suction tube immediately upon generation. Furthermore, by enclosing part of the blade body within the first suction tube and the other part within the mounting portion, the exposed blade body is reduced, thereby improving safety during use and achieving two benefits.

Description

Technical Field

[0001] This utility model relates to medical electrosurgical units, and more particularly to a high-frequency medical electrosurgical unit. Background Technology

[0002] Medical high-frequency electrosurgical units are characterized by simple operation, safety, and high efficiency, and are an alternative to medical scalpels. As a medical device, medical high-frequency electrosurgical units are widely used in dermatology.

[0003] Chinese utility model patent (application number: 202021737397.X, publication number: CN213310251U) discloses a medical electrosurgical head that is easy to clean, but in actual use, it still has the following shortcomings: commonly used medical high-frequency electrosurgical heads are prone to producing smoke during use, which can easily affect the doctor's vision and thus affect the effect of use. Utility Model Content

[0004] This utility model provides a medical high-frequency electrosurgical unit, the main purpose of which is to overcome the defect that the medical high-frequency electrosurgical unit cannot remove smoke in time during use.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This disclosure provides a medical high-frequency electrosurgical unit, comprising:

[0007] The actuator has a long blade and a blade head set on the front end of the blade, the blade head being used to achieve an electric burning effect after being heated by electricity;

[0008] The control unit, the tail end of which is electrically connected to an external power source, is equipped with a control button for controlling the heating of the actuator, and the rear end of the blade is located on the front end of the control unit; and

[0009] A first suction pipe, the front end of which is configured as an air inlet, an exhaust passage inside the first suction pipe is connected to the air inlet, and at least one mounting part is obliquely provided on the first suction pipe, the mounting part having a cavity, the cavity being provided along the length extension direction of the mounting part;

[0010] The front end of the cavity is connected to the air inlet. The actuator is inserted from the rear end of the cavity so that the front end of the blade extends exposed to the outside of the air inlet. A portion of the blade is inclinedly disposed within the air inlet so that a portion of the blade is enclosed within the first suction pipe. There is at least one gap between the blade and the air inlet so that outside air can flow through the air inlet into the first suction pipe. Another portion of the blade is inclinedly disposed within the cavity so that another portion of the blade is enclosed within the mounting portion.

[0011] In one possible implementation, the slit is provided around the outer periphery of the blade.

[0012] In one possible implementation, the gap extends between the air inlet and the cutter head.

[0013] In one possible implementation, a second suction pipe is detachably fitted at the rear end of the first suction pipe. One end of the second suction pipe is connected to an exhaust fan, which provides suction to the second suction pipe and the first suction pipe so that when smoke appears at the air inlet, the smoke is drawn into the first suction pipe and the second suction pipe through the air inlet.

[0014] In one possible implementation, the diameter of the cavity is larger than the diameter of the blade.

[0015] In one possible implementation, an extension sleeve is detachably mounted on the front end of the first suction tube, the extension sleeve being arranged around the outer periphery of the cutter head such that at least a portion of the cutter head is disposed within the extension sleeve.

[0016] In one possible implementation, the blade has an insulating portion, and at least one limiting block is provided in the mounting portion. The bottom of the limiting block is disposed around the inner wall of the mounting portion, and the top of the limiting block extends into the cavity, so that when the blade is inserted into the cavity, at least a portion of the insulating portion is engaged with the limiting block, thereby fixing the depth of the blade inserted into the cavity.

[0017] In one possible implementation, when the first intake tube is arranged below the control unit, at least a portion of the second intake tube is arranged below the control unit by at least one locking fastener.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model has a simple structure and strong practicality. By connecting the front end of the cavity to the air inlet, and inserting the actuator from the rear end of the cavity, the front end of the blade extends exposed to the outside of the air inlet. On the one hand, this brings the air inlet closer to the blade, allowing the smoke to be sucked into the first suction pipe as soon as it is generated. On the other hand, by enclosing part of the blade inside the first suction pipe and the other part inside the mounting part, the exposed blade is reduced, thereby improving safety during use and achieving two benefits at once.
