The utility model discloses to executing operation environment and the operation demand of tonsil subtotal art, improved the structure of high frequency electrotome for in the high frequency electrotome more was applicable to tonsil subtotal art, can help the operation person safety, quick, accurate completion tonsil subtotal art.

When this scheme of design, the present inventor still considers simultaneously, needs very stable and accurate to tool bit 4's control during the tissue excision, and outer tube 1 and inner tube 2 all adopt plastic material to make, whether can influence the rigidity of structure for the high frequency electric sword grips the in-process, receives tool bit 4 gravity to influence, makes tool bit 4's angle take place the skew. Aiming at the problem, the inventor carries out practical tests, which specifically comprise the following steps:

the outer tube 1 and the inner tube 2 are both made of TPE (Thermoplastic elastomer) and are dimensioned as described above. The conducting wire 3 is a copper core conducting wire with the diameter of about 0.8-1 cm. The copper core wire has certain rigidity, the rigidity of the copper core wire with the diameter of 0.8cm can reach 80N/m, and the outer pipe 1 and the inner pipe 2 also have certain rigidity, so that the rigidity of the whole structure of the outer pipe 1, the inner pipe 2 and the copper core wire 3 can reach about 120N/m. The weight of the cutting head 4 is generally very light, about 20-30g, and the generated gravity is about 0.2-0.3N. The gravity of the cutter head 4 is far less than the force required for bending the whole structure, and the high-frequency electric knife is combined with the use characteristics of the high-frequency electric knife, which is different from the traditional cutting mode of a mechanical knife, and the high-frequency electric knife cuts the tissue through the high temperature generated by the high-frequency current, so that the interaction force between the high-frequency electric knife and the tissue during cutting can be avoided. When the operator grips high frequency electric knife row tonsil subtotal art promptly, outer tube 1, inner tube 2, the whole power that receives of copper core wire structure roughly equals with the gravity of tool bit 4, and because the gravity of tool bit 4 is far less than and makes the whole required power of buckling that takes place of structure, so outer tube 1, inner tube 2, the whole support tool bit 4 that can stabilize very much of copper core wire structure, tool bit 4 can not take place the skew in the motion process yet, can satisfy in the tonsil subtotal art stability, the demand of accurate lower sword. Meanwhile, the inventor also carries out a plurality of practical tests, and the plurality of tests show that the whole structure of the outer tube 1, the inner tube 2 and the copper core wire can stably support the cutter head 4, the angle of the cutter head 4 can be changed only when an operator applies a large bending force to the outer tube 1 through an arm, and the cutter head 4 can keep a relatively fixed state and is not easy to shift when the operator does not receive a large external force. The high-frequency electric knife can be practically applied to tonsil partial resection.

Furthermore, in this embodiment, an insulating protective layer (not shown in the figure) is coated outside the connection position of the tool bit 4 and the wire 3, the insulating protective layer is disposed around the connection position of the wire 3 and the tool bit 4, and the insulating protective layer can prevent the electric leakage at the connection position of the tool bit 4 and the wire 3, so that the high-frequency electric knife has higher safety.

More specifically, the silica gel material can be selected for use to make by insulating inoxidizing coating, and the silica gel material has good insulating nature, and the silica gel material matter is soft, can not cause the damage to oral cavity and pharyngeal mucosa, can not cause the hindrance to the angle modulation of tool bit 4 simultaneously.

Furthermore, in this embodiment, the outer surface of the middle section of the outer tube 1 is provided with anti-slip lines (not shown in the figure), and the anti-slip lines may be specifically skewed tooth lines, cross lines or other common anti-slip lines, and may be directly formed on the outer surface of the middle section of the outer tube 1. The middle section of the outer tube 1 is used for holding the operator in the operation, so that the middle section of the outer tube 1 is provided with anti-slip lines to increase the friction force between the hand of the operator and the outer tube 1, and the holding of the high-frequency electric knife is more stable.

Furthermore, in this embodiment, the end of the suction head 12 is in a trumpet shape, and the opening angle thereof is 120 to 150 °, so that the structure of the suction head 12 can better collect and suck the smoke, thereby the effect of sucking the smoke is better and the efficiency is higher.

Further, in the embodiment, the negative pressure joint 11 extends to the side of the outer pipe 1 obliquely to the outer pipe 1, and the inclination angle between the negative pressure joint 11 and the outer pipe 1 is 30-40 °. The negative pressure joint 11 and the outer tube 1 form an angle, so that when smoke flows into the negative pressure joint 11 from the smoke channel 5, the bent angle is small, and the smoke flows smoothly in the process of smoking. And certain clearance is left between the negative pressure joint 11 and the outer tube 1, so that the operation when the negative pressure joint 11 is connected with the negative pressure device can be facilitated, the joint of the outer tube 1 and the negative pressure device is prevented from generating interference, and on the other hand, the negative pressure joint 11 is relatively close to the outer tube 1, so that the visual field shielding of an operator in the operation is small.

Furthermore, in this embodiment, the negative pressure connector 11 is a bell mouth with an internal taper, and the negative pressure connector 11 with such a structure can be conveniently connected with the negative pressure device, and is stable in connection and not easy to fall off.

Furthermore, in this embodiment, annular tool bit or circular tool bit are selected for use to tool bit 4, and annular tool bit and circular tool bit more are applicable to among the tonsil partial excision, have the accurate, fast advantage of blood coagulation of excision.

Furthermore, in this embodiment, the plastic insulating material can be selected from TPE, which is an elastic plastic and has good insulating properties. And the hardness and flexibility are moderate, on one hand, the cutting head has enough rigidity to support the cutting head 4, the cutting head cannot be easily deformed, and the tonsil partial resection can be stably completed. On the other hand, the material itself has enough flexibility, can generate plastic deformation when exerting enough external force, can change the shape of the knife head to a certain extent, and further adjust the angle of the knife head 4, so that the high-frequency electrotome can be better suitable for tonsil partial resection.

Further, in this embodiment, be equipped with the filter screen (not shown in the figure) in the negative pressure joint 11, the smog that the negative pressure device smoked contains the large granule, and the in-process of smog of suction simultaneously can be by the art internal hemorrhage and other filths, and long-time suction large granule and filth can lead to the negative pressure device to damage, therefore set up the filter screen in negative pressure joint 11 to filtering large granule and filth prevent that large granule and filth from damaging the negative pressure device.
