Description

Technical Field

[0001] This application relates to the technical field of medical devices, and in particular to an illuminated high-frequency electrosurgical unit. Background Technology

[0002] The high-frequency surgical electrosurgical pen is one of the main instruments for tissue cutting in surgical procedures. It mainly consists of three parts: a surgical metal electrode at the head, a handle at the body, and a power cord at the tail. The handle comprises a housing, a circuit inside the housing, and circuit control switches mounted on the outer wall of the housing. These circuit control switches include an electrocoagulation switch and an electrocautery switch. In use, the power is connected, and the corresponding switch is turned on. The high-frequency current generated by the surgical metal electrosurgical pen head is used to cut and separate tissue or electrocoagulate for hemostasis.

[0003] However, during the surgery, although shadowless lamps are used for surgical field illumination, they cannot meet the actual lighting needs due to factors such as the depth of the lesion, the location of the incision, the shadow cast by the body, and the angle of the light.

[0004] Chinese patent CN214678999U discloses a medical high-frequency electrosurgical unit with illumination function. The unit includes an electrosurgical body with a fixed outer shell. A mounting shell is fixedly connected to the front end of the electrosurgical body, and a connecting tube is fixedly connected to the front end of the mounting shell. Illuminating lamps are fixedly connected inside the mounting shell, arranged in a ring at equal intervals, and electrically connected to a power supply device. This medical high-frequency electrosurgical unit with illumination function increases surgical visibility and allows for convenient adjustment of the blade type according to actual needs.

[0005] The aforementioned technologies have the following drawbacks: Although multiple lights arranged in a ring on the handle can significantly increase the illumination range of the light group and ensure that there are no blind spots in the illumination of the blade area, they are limited by the different wound sizes. Although the ring lights have a large illumination area, when performing surgery on tissues with smaller wounds, too much light shining around the wound can easily cause glare, leading to visual fatigue and thus affecting the quality of the procedure. Utility Model Content

[0006] To address the issue of the inability to adjust the illumination area of ​​a ring light, this application provides a high-frequency electrosurgical unit capable of illumination.

[0009] Further, the end of the outer sleeve away from the electrode extends in a direction away from the electrode, and the end of the inner sleeve extends along the end surface of the handle in a direction away from the electrode and abuts against the outer sleeve.

[0010] Further, a damping structure is arranged between the inner peripheral wall of the end of the outer sleeve away from the electrode and the outer peripheral wall of the inner sleeve.

[0011] Further, the damping structure comprises a damping rubber ring sleeved on the outer wall of the inner sleeve, and the damping rubber ring is embedded on the inner peripheral wall of the outer sleeve.

[0020] The technical solutions of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0021] An illuminable high-frequency electrotome is disclosed in an embodiment of the present application. Referring to Figure 1 and Figure 2 An illuminable high-frequency electrotome comprises an electrode 11, a handle 12 and a power cord 13. The handle 12 is provided with a plurality of lamp beads 2 arranged in a ring near the end face of the electrode 11. An inner sleeve 3 is sleeved on one end of the handle 12 close to the electrode 11, and the transition surface of the inner sleeve 3 is adapted to the end of the handle 12. An outer sleeve 4 is coaxially sleeved on the outer part of the inner sleeve 3. A silica gel ring 5 is connected between the inner sleeve 3 and the outer sleeve 4. The outer circumferential side of the silica gel ring 5 is fixed to the inner side wall of the outer sleeve 4, and the inner circumferential side is fixed to the outer side wall of the inner sleeve 3. The plurality of lamp beads 2 are arranged on the silica gel ring 5 in a spaced manner. An adjusting mechanism is arranged on the handle 12 for driving the outer sleeve 4 to move along the length direction of the handle 12.

[0022] After being arranged in this way, during the operation of the operator, the power cord 13 is connected, and the handle 12 is held. The outer sleeve 4 can be driven to move relative to the inner sleeve 3 by means of the adjusting mechanism. Since the silica gel ring 5 is relatively soft, it can be twisted and deformed to a certain extent. Therefore, at this time, the outer sleeve 4 can drive the silica gel ring 5 to deflect on the inner sleeve 3, that is, the included angle between the silica gel ring 5 and the inner sleeve 3 changes, so that the direction of the lamp beads 2 on the silica gel ring 5 changes, and the illumination range of the plurality of lamp beads 2 can be changed to adapt to different illumination needs. The visual fatigue caused by the reflection of the large illumination range can be significantly reduced, and the operation quality can be improved.

[0023] Specifically, referring to Figure 1, the end of the outer sleeve 4 away from the electrode 11 extends away from the electrode 11, and the end of the inner sleeve 3 extends along the inclined surface of the end of the handle 12 away from the electrode 11 and is attached to the outer sleeve 4. The adjusting mechanism includes a pull bar 42 fixed to the closed end of the outer sleeve 4, the end of the pull bar 42 away from the electrode 11 extends to the holding part of the handle 12, and the pull bar 42 is also provided with anti-skid structures such as anti-skid protrusions, anti-skid grooves, etc.

[0024] In this way, the outer sleeve 4 can be coaxially and closely fitted with the inner sleeve 3, so that the sliding of the outer sleeve 4 on the handle 12 is more stable, and the phenomenon of deflection of the outer sleeve 4 does not occur when the outer sleeve 4 is pushed by the pull bar 42, ensuring the uniformity of the deflection of the silica gel ring 5, so that the multiple lamp beads 2 can be adjusted as synchronously as possible. And with the pull bar 42 on the closed end of the outer sleeve 4, the light adjustment of the high-frequency electric knife can be realized with one hand, which is more convenient to operate.

[0025] At the same time, referring to Figure 1 and Figure 2 , the inner circumferential wall of the end of the outer sleeve 4 away from the electrode 11 is provided with a damping structure between the outer circumferential wall of the inner sleeve 3; the damping structure includes a damping rubber ring 6 fitted on the outer wall of the inner sleeve 3, and the damping rubber ring 6 is embedded in the inner circumferential wall of the outer sleeve 4. According to the actual setting, the damping rubber ring 6 can be provided in multiple along the axial direction of the inner sleeve 3 to improve the stability of the outer sleeve 4 on the inner sleeve 3. In this way, the sliding resistance of the outer sleeve 4 on the inner sleeve 3 can be increased to some extent, so that the operator can control the position of the outer sleeve 4 more accurately when adjusting the position of the outer sleeve 4, and the outer sleeve 4 will not move on the inner sleeve 3, improving the stability of the application in use. And the damping rubber ring can also effectively avoid the twisting problem of the lamp beads 2 when adjusting the light, and avoid the vibration of the electrode 11 outputting at too high a frequency to reduce the vibration of the lamp beads 2, thereby improving the operation and life of the lamp beads 2.

[0026] In addition, in order to avoid the twisting of the silica gel ring 5 driven by the outer sleeve 4 when the outer sleeve 4 is pushed, referring to Figure 1 and Figure 2 , a guide bar 41 is also fixed to the inner side wall of the outer sleeve 4 along the length direction of the handle 12, and a guide groove 31 is formed in the outer circumferential wall of the end of the inner sleeve 3 away from the electrode 11, and the guide bar 41 is slidably arranged in the guide groove 31. To ensure that the pull bar does not rotate on the inner sleeve 3 when pushing the outer sleeve 4 due to different force directions.

[0027] In addition, referring to Figure 1The outer sleeve 4 protrudes from the inner sleeve 3 at one end near the electrode 11. A reflective layer 7 is provided on the inner peripheral wall of the outer sleeve 4. Specifically, the reflective layer 7 can be a diffuse reflective coating. The reflective layer 7 is provided on the side of the silicone ring 5 near the electrode 11. In another feasible embodiment, a reflective layer 7 can also be provided on the side of the silicone ring 5 near the electrode 11.

[0028] With this setup, the reflective layer 7 is designed on the inner circumferential wall of the outer sleeve 4, which can effectively concentrate light and maximize the brightness of multiple LED beads 2 during illumination.

[0029] The implementation principle of a high-frequency electrosurgical unit capable of illumination according to an embodiment of this application is as follows:

[0030] During the procedure, the operator connects the power cord 13 and holds the handle 12. The adjustment mechanism can be used to move the outer sleeve 4 relative to the inner sleeve 3. Since the silicone ring 5 is relatively soft, it can undergo a certain degree of torsional deformation. Therefore, the outer sleeve 4 can cause the silicone ring 5 to deflect on the inner sleeve 3, that is, the angle between the silicone ring 5 and the inner sleeve 3 changes. This changes the direction of illumination of the LED beads 2 on the silicone ring 5, thereby changing the illumination area of ​​multiple LED beads 2 to adapt to different lighting needs. This can significantly reduce the visual fatigue caused by reflections due to excessively large illumination areas, thereby improving the quality of the procedure.
