[0002] A high-frequency surgical device, also known as a high-frequency electric knife, is an electrosurgical instrument that replaces mechanical scalpels for tissue cutting. It heats tissue when it comes into contact with the body through high-frequency, high-voltage current generated by the active electrode tip, separating and coagulating tissue, thereby achieving the purpose of cutting and stopping bleeding.

[0003] A high-frequency electrosurgery unit is a variable-frequency transformer that discharges high-frequency current into human tissue, generating a high-frequency current. Because the contact area between the surgical electrode tip and biological tissue is very small, the current density is very high, producing both a cutting and coagulation effect on human tissue. Existing high-frequency electrosurgeries can simultaneously perform both cutting and coagulation, making them widely used in procedures difficult to access and perform with mechanical scalpels, such as abdominal duct ligation and prostate urethral tumor resection. Due to their excellent hemostatic effects, high-frequency electrosurgeries can also be used to operate on organs with exudative capillaries, such as the liver, spleen, thyroid gland, and lungs, as well as in thoracotomy procedures requiring large amounts of anticoagulants.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a quick disassembly and assembly device for a high-frequency electric knife, comprising a handle 1, and a plurality of groups of evenly distributed anti-slip grooves are provided on the outer wall of the handle 1, which increases the friction between the palm of the staff and the handle 1 and improves the anti-slip property of the handle 1. A disassembly component 4 is provided on the upper surface of the handle 1, and the staff improves the convenience of replacing the electric knife component 5 through the function of the disassembly component 4. The electric knife component 5 is provided on the upper side of the bottom surface of the inner wall of the connecting tube 43, and the electric knife component 5 supports the electric knife head 52. The circuit is connected to the connecting wire 3 at the axis center of the lower surface of the handle 1, and an auxiliary component 2 is provided on the outer side of the lower surface of the handle 1 near the connecting wire 3.

[0024] Reference Figure 1 - Figure 3When the staff needs to connect an electric knife adapted to a different circuit diagram, the disassembly component 4 is started. The disassembly component 4 includes a mounting base 41, which is fixedly connected to the axis of the upper surface of the handle 1. The axis of the upper surface of the mounting base 41 is fixedly connected to a connecting tube 43. Two groups of circular grooves 42 are opened on the upper surface of the mounting base 41 near the outside of the connecting tube 43. The bottom of the inner wall of the circular groove 42 is fixedly connected to a mounting block 46 through an elastic rod 45. After the device is powered off, the staff manually presses the mounting block 46, and the bottom of the elastic rod 45 is fixedly connected to the bottom of the inner wall of the circular groove 42. In the middle, the top of the elastic rod 45 is fixedly connected to the lower surface of the mounting block 46. The inner arc surface of the inner wall of the mounting block 46 is provided with two sets of strip grooves 47. The mounting block 46 moves downward under the action of the extrusion force, causing the elastic rod 45 to shrink, causing the strip groove 47 to move downward to the hole groove in the connecting tube 43. The cross-sectional area of the hole groove in the outer arc surface of the electric knife seat 51 is slightly larger than the cross-sectional area of the outer wall of the ball 49. The outer arc surface of the outer wall of the connecting tube 43 is provided with a mounting groove 44. The inner arc surface of the inner wall of the mounting groove 44 is detachably connected to a fixing ring 48. The outer arc surface of the outer wall of the connecting tube 43 The ball 49 is connected to the hole groove of the connecting tube 43 in a rolling manner. Due to the downward movement of the strip groove 47, the effective space of the ball 49 in the connecting tube 43 increases, and the electric knife seat 51 moves upward, so that the ball 49 moves toward the strip groove 47 under the upward force, thereby releasing the limiting effect on the electric knife seat 51, so that the electric knife head 52 is separated from the connecting tube 43 under the upward force of the electric knife seat 51, realizing the rapid replacement of the electric knife assembly 5 by the staff through the use of the disassembly assembly 4. The electric knife assembly 5 includes the electric knife seat 51, and the lower surface of the electric knife seat 51 is plugged into the connecting tube 43. At the bottom of the inner wall, the electric knife seat 51 is connected to the inside of the mounting block 46, and the electric knife head 52 is fixedly connected to the upper surface of the electric knife seat 51. The matching electric knife components 5 are placed in the connecting tube 43 again, and the squeezing effect on the mounting block 46 is cancelled. The elastic rod 45 drives the mounting block 46 to move upward, so that the strip groove 47 moves upward to squeeze the ball 49 inward, so that the ball 49 is reset to the hole groove of the electric knife seat 51, completing the positioning of the electric knife assembly 5, ensuring the stability of the device, and enhancing the convenience of the staff when using the disassembly component 4.

[0025] Reference Figure 2 - Figure 4When the staff uses the electric knife for surgery, the auxiliary component 2 is activated. The auxiliary component 2 includes a positioning seat 21, which is fixedly connected to the lower surface of the handle 1 near the outside of the connecting line 3. A positioning groove 25 is provided at the axis of the upper surface of the positioning seat 21. The connecting line 3 is connected to the inside of the positioning seat 21. As the position of the electric knife device controlled by the handle 1 changes, the connecting line 3 is subjected to different degrees of bending. The inner wall of the positioning groove 25 is fixedly connected to a rubber clamping claw 24. The rubber clamping claw 24 in the positioning seat 21 clamps the outer wall of the connecting line 3, so that the rubber The clamping claws 24 have a positioning and clamping effect on the connector of the connecting wire 3, which improves the stability of the connecting wire 3. The upper surface of the positioning seat 21 is detachably connected to a rubber strip 23, and the end of the rubber strip 23 is fixedly connected to an anti-static ring 22. The rubber strip 23 cooperates with the anti-static ring 22 to wrap the connecting wire 3, and provides stress support for the bending part of the connecting wire 3 at the bottom of the handle 1, thereby avoiding the phenomenon of the connecting wire 3 breaking due to long-term large-angle bending, improving the protection of the electric knife equipment during use, and enhancing the protection effect of the staff when operating the electric knife.

[0026] Working principle: When the staff needs to connect an electric knife adapted to a different circuit diagram, the disassembly component 4 is started. After the power is cut off, the staff manually presses the mounting block 46. The mounting block 46 moves downward under the action of the extrusion force, causing the elastic rod 45 to contract, resulting in the strip groove 47 moving downward to the hole groove in the connecting tube 43, so that the effective space of the ball 49 in the connecting tube 43 increases, and the electric knife seat 51 moves upward, causing the ball 49 to move toward the strip groove 47 under the upward force, thereby releasing the limiting effect on the electric knife seat 51, so that the electric knife head 52 is separated from the connecting tube 43 under the upward force of the electric knife seat 51, realizing the rapid replacement of the electric knife assembly 5, and putting the mutually matching electric knife assembly 5 into the connecting tube 43 again, canceling the extrusion effect on the mounting block 46, and the elastic rod 45 drives the mounting block 46 to move upward, causing the strip groove 47 to move upward to squeeze the ball 49 inward. The pressure causes the ball 49 to be reset to the hole groove of the electric knife seat 51, completing the positioning of the electric knife assembly 5, ensuring the stability of the device, and enhancing the convenience of the staff in using the disassembly assembly 4. When the staff uses the electric knife for surgery, the auxiliary component 2 is started. Due to the change in position of the electric knife device controlled by the handle 1, the connecting wire 3 is subjected to different degrees of bending. The rubber claws 24 in the positioning seat 21 clamp the outer wall of the connecting wire 3, so that the rubber claws 24 have a positioning and clamping effect on the connection head of the connecting wire 3, thereby improving the stability of the connecting wire 3. The rubber strip 23 cooperates with the anti-static ring 22 to wrap the connecting wire 3, and provides stress support for the bending part of the connecting wire 3 at the bottom of the handle 1, thereby avoiding the phenomenon of the connecting wire 3 being broken due to long-term large-angle bending, thereby improving the protection of the electric knife equipment during use and enhancing the protection effect of the staff in operating the electric knife.
