Description

Technical Field

[0001] The utility model belongs to surgical instruments, and particularly relates to a high-frequency electrotome main unit. Background Art

[0002] A high-frequency electrotome is an electro-surgical instrument that replaces a mechanical scalpel for tissue cutting. When the high-frequency high-voltage current generated by the effective electrode tip contacts the body, the tissue is heated, so as to separate and coagulate the body tissue, and finally achieve the purposes of cutting and hemostasis. With the development of medical technology and the improvement of clinical requirements, composite electro-surgical devices mainly based on high-frequency electrotomes have developed greatly. Since the high-frequency electrotome directly acts on human tissue with high-frequency current, extremely strict requirements are imposed on its safety. A common high-frequency electrotome usually includes a main unit and a high-frequency electrode that is detachably electrically connected to the main unit. The high-frequency electrode usually consists of a surgical electrode and a cooperatively arranged neutral electrode. The main unit usually includes a housing and components such as a controller, a power amplifier, a filter, and an alarm arranged in the housing. During the working process of the high-frequency electrotome, the main unit generates a lot of heat. The conventionally arranged main unit housing only has heat dissipation holes for heat dissipation of power devices, and the heat dissipation efficiency is low, resulting in a high temperature of the main unit and there are potential safety hazards. In addition, the conventionally arranged high-frequency electrotome main unit usually only has foot pads. It is very inconvenient to adjust the placement angle of the surgical operation when the high-frequency electrotome main unit is placed. Content of the Utility Model

Detailed implementation manners

[0032] To make the purposes, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the Figures 1 to 11 accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model fall within the scope of protection of the present utility model.

[0033] Embodiment 1: As Figures 1 to 4 shown in the embodiment, a high-frequency electrotome main unit of the present utility model, the high-frequency electrotome main unit 100 includes a main unit box body 1 and a main unit box cover 2. A controller and power devices such as a power amplifier, a filter, and an alarm electrically connected to the controller are installed in the main unit box body 1. The controller can implement its functions by using a single-chip microcomputer. The controller is electrically connected to an external power supply. The current output end of the controller amplifies the current through the power amplifier and the filter, and a high-frequency source is connected to the signal receiving end of the power amplifier. The output end of the power amplifier is connected to a high-frequency electrode, and high-frequency current is output by the surgical electrode in the high-frequency electrode for surgical operations. Chinese Patent CN203935271U discloses "a high-frequency electrotome for real-time monitoring and displaying the temperature of a neutral electrode", and this patented technology discloses a similar high-frequency electrotome technology.

[0034] As Figure 2As shown, the front end of the main box body 1 is provided with a plug-in connection board 5 for connecting the high-frequency electrode, the plug-in connection board 5 is electrically connected to the controller, and the surgical electrode and the neutral electrode of the high-frequency electrode are detachably connected to the plug-in connection board 5 through wires, respectively, to facilitate the replacement of the high-frequency electrode. The front side of the main box cover 2 is provided with an inclined surface and a touch screen 22 arranged on the inclined surface, the touch screen 22 is electrically connected to the controller, and the human-computer interaction operation is realized through the touch screen 22, and the real-time output frequency adjustment is realized.

[0035] like Figure 1 and Figure 4 As shown, a mounting hole 12 is provided on one side wall of the mainframe box body 1, and a heat dissipation mechanism 4 is mounted in the mounting hole 12. The heat dissipation mechanism 4 includes a heat dissipation box body 41, and at least one heat dissipation fan 43 connected to the inner cavity of the mainframe box body 1 is provided on the inner side of the heat dissipation box body 41, and a heat dissipation grille 42 is provided on the outer side of the heat dissipation box body 41; at least one side of the mainframe box body 1 or / and the mainframe box cover 2 is provided with a plurality of heat dissipation holes 21. Specifically, the heat dissipation fan 43 includes 2 to 3 heat dissipation holes 21 arranged in parallel along the width of the heat dissipation box body 41; the heat dissipation holes 21 can be correspondingly arranged on one side wall of the mainframe box cover 2, or on the side wall of the mainframe box body 1, and the heat dissipation holes 21 can provide airflow exchange between the inside and outside of the high-frequency electric knife mainframe, and the heat dissipation fan 43 forcibly extracts the high-temperature gas inside the high-frequency electric knife mainframe, thereby realizing forced heat dissipation and improving the heat dissipation efficiency of the high-frequency electric knife mainframe.

[0036] Example 2: Based on Example 1, Figures 3 to 5 As shown, the front side of the bottom of the mainframe box body 1 is recessed toward the inside of the box body to form a storage cavity 11 and a support frame 3 that can be flipped and coupled in the storage cavity 11. The two side walls of the storage cavity 11 are respectively provided with a rotation adjustment component 6. The support frame 3 is a U-shaped structure, and the ends of the rods on both sides of the support frame 3 are respectively connected to the rotation adjustment component 6. The support frame 3 can be flipped and adjusted by 0~110° along the storage cavity 11 by the rotation adjustment component 6, so as to meet the operator's adjustment of the placement angle of the high-frequency electric knife mainframe under different conditions.

[0037] In a specific embodiment, if Figures 6 to 10As shown, the rotation adjustment assembly 6 includes a first connection end 61 fixedly connected to the inner side wall of the storage cavity 11 and a second connection end 62 fixedly connected to the end 31 of the rod body of the support frame 3. The outer end face of the first connection end 61 and the inner end face of the second connection end 62 are respectively provided with a first tooth-shaped surface 611 and a second tooth-shaped surface 621 distributed circumferentially, and the second tooth-shaped surface 621 can be meshed and connected with the first tooth-shaped surface 611 to form an integral body. Through holes for the adjustment screw 63 to pass through are formed at the axes of the first connection end 61 and the second connection end 62. The adjustment screw 63 passes through the through holes of the first connection end 61 and the second connection end 62. A smooth end of the adjustment screw 63 located outside the second connection end 62 is fixedly connected with an adjustment handwheel 65, and a limit sleeve 64 is arranged between the adjustment screw 63 and the second connection end 62 inside the adjustment handwheel 65. The limit sleeve 64 connects the second connection end 62 and the adjustment screw 63 and restricts the second connection end 62 and the adjustment screw 63 from performing synchronous rotation actions, and the adjustment screw 63 can drive the second connection end 62 to axially move away from the first connection end 61. The threaded end of the adjustment screw 63 passes through the first connection end 61 and extends into the inner cavity of the main machine box body 1, and is threadedly connected with a limit ring 66 arranged in the inner cavity of the main machine box body 1. There is a certain gap between the limit ring 66 and the side wall of the storage cavity 11, so as to meet the requirement of axially moving adjustment of the adjustment screw 63. A connection spring 67 for driving the second connection end 62 and the first connection end 61 to be in a meshed and clamped state is also arranged between the second connection end 62 and the first connection end 61. The connection spring 67 is correspondingly sleeved on the adjustment screw 63. In this embodiment, first counterbores 612 and second counterbores 622 are respectively formed axially inward at the connection surfaces of the adjacent ends of the first connection end 61 and the second connection end 62, and the connection spring 67 is connected in a tension state in the first counterbores 612 and the second counterbores 622.

[0038] As Figure 5As shown in the figure, the support frame 3 with a U-shaped structure is made of plastic material with a certain deformation ability, or stainless steel or aluminum profiles, so that the two rod ends 31 at the U-shaped open end of the support frame 3 can be deformed inward or outward to a certain extent. When it is necessary to adjust the support angle of the support frame 3, the adjustment handwheels 65 of the two groups of rotation adjustment components 6 are pulled synchronously. The adjustment handwheel 65 drives the adjustment screw 63 to move outward, overcoming the pulling force of the connecting spring 67, driving the second connecting end 62 to move outward. The second connecting end 62 drives the rod end 31 connected thereto to deform, so that the first tooth-shaped surfaces 611 and 621 of the first tooth-shaped surface 611 and the second tooth-shaped surface 621 are disengaged from contact. At this time, rotating the adjustment handwheel 65 synchronously can drive the support frame 3 to rotate along with the adjustment screw 63 to adjust the support angle of the support frame 3; when the support frame 3 is adjusted in place, the restriction on the adjustment handwheel 65 is released. Under the traction of the connecting spring 67, the adjustment screw 63 drives the second connecting end 62 and the rod end 31 to reset, so that the first tooth-shaped surfaces 611 and 621 of the first connecting end 61 and the second connecting end 62 are engaged and connected, thereby restricting the relative rotation between the first connecting end 61 and the second connecting end 62 and realizing the position fixation of the support frame 3.

[0039] Embodiment 3: The difference from the rotation adjustment component in Embodiment 2 lies in the position where the connecting spring 67 is arranged. In this embodiment, a clamping counterbore 613 is opened at the axis of one end of the first connecting end 61 close to the storage cavity 11. The connecting spring 67 is supported in a compressed state between the limiting ring 66 and the clamping counterbore 613. When the rotation adjustment component 6 is in the locked state, the connecting spring 67 supports the limiting ring 66 to drive the adjustment screw 63 and the second connecting end 62 thereon to be in an engaged connection state with the first connecting end 61. If it is necessary to adjust the support angle of the support frame 3, the adjustment process is substantially the same as that in Embodiment 2, and the only difference is the position and stretching state of the connecting spring.

[0040] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
