Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical instruments and relates to an electric knife with a smoking sleeve. Background Art
[0002] High-frequency electrosurgical units use high-frequency current to generate instantaneous high temperatures, heating tissues and causing local carbonization to facilitate rapid tissue cutting and hemostasis. A certain amount of smoke is produced during the tissue carbonization process, which not only affects the surgical operating environment, but also interferes with the surgical field of view to a certain extent.
[0003] There are also some smoke extraction sets compatible with electric knife in the prior art, but they are generally directly mounted on the handle of the electric knife, and a smoking air inlet pipe is arranged at the front end of the extraction set, and the smoke is drawn to the exhaust hose at the upper end of the smoking set through the inner cavity of the smoking set, and the exhaust hose is externally connected to a vacuum pump. This method not only increases the outer diameter of the handle of the electric knife, making the operator fatigue-prone, but also has the problem of a small smoke suction air intake surface (the smoking air intake is achieved by placing the suction pipe head next to the knife head), resulting in a poor smoking effect. Utility Model Content
[0004] The purpose of the utility model is to provide an electric knife with a smoking sleeve in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to increase the air intake cross section and improve the air suction effect.
[0005] The purpose of the utility model can be achieved through the following technical solutions: an electric knife with a smoking sleeve, the electric knife includes a rod-shaped handle and a knife head located at the front end of the handle, characterized in that the smoking sleeve includes a sleeve adapted to the handle, a ventilation interlayer is provided in the sleeve, the top of the sleeve has an exhaust pipe connected to the ventilation interlayer, the lower end of the sleeve has an air inlet bevel with an inclination angle of 30 to 70 degrees with the diameter of the sleeve, the air inlet bevel is connected to the ventilation interlayer, and a grille is arranged at the air inlet bevel.
[0006] Furthermore, the sleeve is provided with an external handle perpendicular to the sleeve, a threaded sleeve penetrating inside and outside the sleeve is fixedly provided on the sleeve, and the inner end of the external handle has a pressing head threadably connected to the threaded sleeve.
[0007] Furthermore, the sleeve has an avoidance gap for avoiding the control area on the electric knife.
[0008] Compared with the prior art, the present invention has a greatly increased smoking air intake cross-section and an external handle surrounding the outer side of the knife head, which is not only used for the fixed assembly of the smoking sleeve and the electric knife, but also can hold the electric knife horizontally to avoid the larger smoking sleeve affecting the operating field of view.

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0015] like Figures 1 to 4 As shown, the electric knife includes a rod-shaped handle 1 and a knife head 2 located at the front end of the handle 1, and the smoking sleeve includes a sleeve 3 adapted to the handle 1, a ventilation interlayer is provided in the sleeve 3, an exhaust pipe 4 connected to the ventilation interlayer is provided at the top of the sleeve 3, and an air inlet oblique port 5 with an inclination angle of 30 to 70 degrees with the diameter of the sleeve 3 is provided at the lower end of the sleeve 3, the air inlet oblique port 5 is connected to the ventilation interlayer, and a grille is provided at the air inlet oblique surface.
[0016] The sleeve 3 is provided with an external handle 6 which is perpendicular to the sleeve 3. A threaded sleeve 7 which passes through the inside and outside of the sleeve 3 is fixedly provided on the sleeve 3. The inner end of the external handle 6 is provided with a pressing head 8 which is threadedly connected with the threaded sleeve 7. The pressing head 8 is pressed against the outer wall of the handle 1 of the electric knife to lock the smoking sleeve and the electric knife. Conversely, the two can be disassembled. The sleeve 3 is provided with an avoidance notch 9 for avoiding the control area on the electric knife.
[0017] In addition, it should be noted that the air inlet bevel 5 is downwardly facing the external handle 61, so that the air inlet bevel tends to be downward, tending towards the smoke generation area. As an optimization, a spiral torsion spring can be connected between the threaded sleeve 7 and the external handle 61, and the two ends of the torsion spring respectively fix the threaded sleeve 7 and the external handle 61. The existence of the torsion spring can not only prevent the external handle 61 from detaching from the sleeve 3, but also the threaded structure can play a role in preventing loosening.
[0018] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
