Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and in particular to an electrocoagulation device with a flushing function. Background Technology
[0002] Minimally invasive surgeries, such as laparoscopy and thoracoscopy, offer advantages such as smaller incisions, less pain, faster recovery, shorter hospital stays, less bleeding, and lower costs. In minimally invasive surgery, surgeons typically use surgical electrodes to cut and dissect the lesion and perform electrocoagulation for hemostasis. Simultaneously, they need to irrigate and suction the surgical site to ensure a clear surgical field. Cutting and dissection, electrocoagulation, and hemostasis are performed using separate specialized instruments, as are irrigation and suction. Because these two specialized instruments are frequently used interchangeably throughout the minimally invasive procedure, the surgeon's workload increases, surgical efficiency is affected, the use of multiple instruments hinders efforts to reduce patient costs, and the prolonged surgery time increases patient discomfort and may even negatively impact the surgical outcome.
[0003] Since the aforementioned electric hook flushing and suction device can combine the functions of two specialized instruments, it can largely make up for the aforementioned deficiencies. Moreover, there is no shortage of technical information about electric hook flushing and suction devices in the published Chinese patent literature, such as CN203988346U (electric hook flushing sleeve), CN105125282B (an electric hook flushing and suction device), CN205359618U (an electric hook flushing and suction device), and CN106510840A (a breast augmentation and plastic surgery device with flushing and suction electric hook), etc.
[0004] However, existing electric hook irrigation and suction devices are usually difficult to operate when performing flushing and aspiration operations, and may even affect the progress of the surgery. Utility Model Content

The second valve body is inserted into the first valve body, and the second valve body has a first through hole for docking with the first channel.
[0010] The first drive button is connected to the second valve body to drive the second valve body to move relative to the first valve body, thereby controlling whether the first through hole and the first channel are connected, and controlling whether the first channel and the first cavity are connected; the toggle part of the first drive button extends to the side wall of the operating handle.
[0011] Optionally, the first channel is connected to a flushing device to input liquid into the first cavity through the first channel;

[0014] The actuating part is exposed on the operating handle and connected to the other end of the rotating link;
[0015] The elastic element is disposed inside the operating handle, and both ends of the elastic element are respectively connected to the inner wall of the operating handle and the rotating connecting rod; or both ends of the elastic element are respectively connected to the inner wall of the operating handle and the second valve body, and the elastic element is used to directly or indirectly apply elastic force to the second valve body, so that the first through hole of the second valve body tends to be disconnected from the first channel.
[0016] Optionally, the first drive button further includes a locking mechanism, which includes a locking pin and a locking groove. The locking pin is elastically mounted on the other end of the rotating linkage, and the locking groove is formed in the operating handle.
[0017] When the actuating part is moved to align the first through hole with the first channel, the locking pin is configured to be partially inserted into the locking groove, thereby fixing the position of the actuating part.
[0018] Optionally, the operating handle is further provided with an operating wrench, which is connected to a suction tube; one end of the suction tube is connected to the operating wrench and is used to dock with the second channel, and the other end of the suction tube is used to communicate with the suction device; pressing the operating wrench can control whether the suction tube is connected to the second channel.
[0019] Optionally, the operating wrench has a second cavity; the second channel and the suction tube extend to opposite sides of the second cavity, respectively;

[0033] Please see Figures 1-3 , Figure 1 This is a schematic diagram of an embodiment of an electrocoagulation device with a rinsing function provided in this application; Figure 2 yes Figure 1 Axial sectional view of the electrocoagulation device shown; Figure 3 yes Figure 1 The diagram shows a structural schematic of one embodiment of the suction mechanism in the electrocoagulation apparatus. It should be noted that... Figure 1 The electrocoagulation device shown has part of its housing removed from the operating handle.
[0034] This application provides an electrocoagulation device with a rinsing function. The electrocoagulation device 10 includes: an operating handle 110, a mounting tube 120, and an electrocoagulation hook 130. One end of the mounting tube 120 is connected to the operating handle 110, and the electrocoagulation hook 130 is disposed on the mounting tube 120 at the end furthest from the operating handle 110. A suction mechanism is provided inside the operating handle. The suction mechanism includes a first valve body 141 and a second valve body 142 nested together, and a first drive button 150. The first valve body 141 has a first cavity 1411, and the mounting tube 120 communicates with the first cavity 1411. A first channel 1412 and a second channel 1413 are provided on the side wall of the body 141. A second valve body 142 is inserted into the first valve body 141, and the second valve body 142 has a first through hole 1421 for docking with the first channel 1412. A first drive button 150 is connected to the second valve body 142 to drive the second valve body 142 to move relative to the first valve body 141, thereby controlling whether the first through hole 1421 is docked with the first channel 1412, and thus controlling whether the first channel 1412 is connected to the first cavity 1411. The toggle part 1501 of the first drive button 150 extends to the side wall of the operating handle 110.
[0035] Therefore, in this embodiment, by extending the toggle part 1501 of the first drive button 150 to the side wall of the operating handle 110, the operator can control the operation by directly toggle the toggle part 1501 with the thumb without changing the gripping action when grasping the operating handle 110; this ensures the stability of the gripping of the operating handle 110, and the flushing pipe can be completed while gripping the operating handle 110.
[0036] The first channel 1412 is connected to the flushing device to input liquid into the first cavity 1411 through the first channel 1412; the second channel 1413 is connected to the suction device to extract liquid from the first cavity 1411 through the second channel 1413.
[0037] The first drive button 150 includes a rotating link 151 and an elastic element 152. The rotating link 151 is rotatably mounted inside the operating handle 110. One end of the rotating link 151 is connected to the second valve body 142, and the other end extends to the side wall of the operating handle 110. The toggle part 1501 is exposed in the operating handle 110 and connected to the other end of the rotating link 151. The elastic element 152 is disposed inside the operating handle 110, and both ends of the elastic element 152 are respectively connected to the inner wall of the operating handle 110 and the rotating link 151. Alternatively, both ends of the elastic element 152 are respectively connected to the inner wall of the operating handle 110 and the second valve body 142. The elastic element 152 is used to directly or indirectly apply an elastic force to the second valve body 142, so that the first through hole 1421 of the second valve body 142 tends to be disconnected from the first channel 1412.
[0038] Please see Figures 4-5 , Figure 4 yes Figure 1 A schematic diagram of the back side of the electrocoagulation device shown; Figure 5 yes Figure 4 The electrocoagulation device shown is a sectional view along section A-A'. It should be noted that... Figure 4 The electrocoagulation device shown has part of the outer casing removed from the back of the operating handle.
[0039] The first drive button 150 also includes a locking mechanism 153, which includes a locking pin 1531 and a locking groove 1532. The locking pin 1531 is elastically mounted on the other end of the rotating connecting rod 151; the locking groove 1532 is formed in the operating handle 110. When the actuating part 1501 is actuated to align the first through hole 1421 with the first channel 1412, the locking pin 1531 is configured to be partially inserted into the locking groove 1532, thus fixing the position of the actuating part 1501. Therefore, when the locking pin 1531 is configured to be partially inserted into the locking groove 1532, the position of the actuating part 1501 can be fixed, so that the first through hole 1421 and the first channel 1412 remain in a connected state, allowing the flushing pipe to flush continuously. After flushing is complete, the push-pull part 1501 can be turned back to the initial position, and the connecting rod 151 can be rotated to return to the initial position under the elastic action of the elastic element 152. At this time, the first through hole 1421 is disconnected from the first channel 1412, and the flushing of the flushing pipe can be stopped.
[0040] Therefore, the locking mechanism 153 can keep the first through hole 1421 and the first channel 1412 in a connected state for continuous flushing, without having to continuously turn the lever 1501, which can further reduce the operation difficulty of the electrocoagulation device 10.
[0041] Furthermore, the operating handle 110 is also equipped with an operating wrench 111, which is connected to a suction tube 101. One end of the suction tube 101 is connected to the operating wrench 111 and is used to dock with the second channel 1413, while the other end of the suction tube 101 is used to connect with a suction device. By pressing the operating wrench 111, the connection between the suction tube 101 and the second channel 1413 can be controlled.
[0042] Furthermore, in this embodiment, the operating wrench 111 has a second cavity 103; the second channel 1413 and the suction tube 101 extend to opposite sides of the second cavity 103 respectively; the operating wrench 111 has a third valve body 104, which is inserted into the second cavity 103; wherein, the third valve body 104 has a recess 1041, and when the third valve body 104 is inserted into the second cavity 103, the recess 1041 and the second cavity 103 form an annular groove; when the operating wrench 111 is pressed so that the second channel 1413 and the suction tube 101 are connected to the annular groove, the second channel 1413 and the suction tube 101 are connected.
[0043] The wrench 111 is equipped with a return spring, which applies an elastic force to the wrench 111, causing it to tend to be in the initial position. Furthermore, when the wrench 111 tends to be in the initial position, the second channel 1413 and the suction tube 101 are disconnected.
[0044] The operating handle 110 is equipped with a flushing pipe 102, which is connected to the first channel 1412. The flushing pipe 102 and the first channel 1412 can be connected by a flexible hose; similarly, the second channel 1413 and the suction pipe 101 can also be connected by a flexible hose.
[0045] A wire 105 is also provided on the operating handle 110, and a circuit board (not shown in the figure) is also provided inside the operating handle 110. The circuit board can be electrically connected to the electrocoagulation hook 130, and the wire 105 is electrically connected to the circuit board. The wire 105 can be electrically connected to an external control device, thereby electrically connecting the electrocoagulation hook 130 to the control device. The control device can send an electrical signal to the electrocoagulation hook 130 to realize the electrocoagulation function of the electrocoagulation hook 130.
[0046] In summary, this application provides an electrocoagulation device with a flushing function. By extending the actuating part of the first drive button to the side wall of the operating handle, the operator can control the device by directly actuating the actuating part with their thumb without changing their gripping action when grasping the operating handle; this ensures the stability of the gripping of the operating handle, and the flushing pipeline can be completed while gripping the operating handle. Furthermore, by employing a locking mechanism, the first through hole and the first channel can remain in a connected state for continuous flushing without having to continuously actuate the actuating part, further reducing the operational difficulty of the electrocoagulation device.
[0047] The above embodiments are merely illustrative examples of this application and not all embodiments. This application may also be implemented in other specific ways or forms without departing from the spirit or essential characteristics of this application. Therefore, the described embodiments should be considered illustrative rather than limiting in any respect.
