DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Please refer to Figs. 1-3 The utility model provides technical scheme: a kind of flush negative pressure multichannel instrument regulator handle, including handle 1, the side of handle 1 is provided with flush button 11 and negative pressure suction button 12, the side of handle 1 is provided with positioning block 13, the side of positioning block 13 is provided with rotatable rotating head 14, the side of rotating head 14 is connected with outer sleeve 15, the inside of outer sleeve 15 is provided with cable tube, the side of cable tube is connected with electrocoagulation hook 21, cable tube and positioning block 13 are connected, the inside of handle 1 is provided with negative pressure suction channel 22 and flush channel 31, the side of handle 1 is provided with adjusting mechanism, flush channel 31 passes through adjusting mechanism, the side of negative pressure suction channel 22 is connected with negative pressure suction interface 2, the side of flush channel 31 is connected with flush interface 3, the inside of cable tube is placed with cable 41, the side of cable 41 is connected with electrocoagulation hook energy interface 4;The flush negative pressure multichannel instrument regulator handle when in use, first, hold entire instrument by handle 1.When needing to switch to flush suction state, first push out rotating head 14, outer sleeve 15 is pushed out, electrocoagulation hook 21 is retracted to the inside of outer sleeve 15, then, operator presses flush button 11 once on the side of handle 1, after hearing click, it indicates that flush channel 31 has been opened. Subsequently, flush liquid flows out from outer sleeve 15. At this time, by adjusting adjusting mechanism on handle 1, the flow of flush channel 31 reaches appropriate level. flush, flush after completion, press flush button 11 again to close flush channel 31.

[0021] Then, the negative pressure suction is performed, the operator presses the negative pressure suction button 12, and after hearing the click sound, it indicates that the negative pressure suction channel 22 has been opened. At this time, the external negative pressure source connected through the negative pressure suction interface 2 starts to work, and the site after flushing is cleaned by suction. After the suction operation is completed, press the negative pressure suction button 12 again to close the negative pressure suction channel 22, and complete the flushing and suction operation.

[0022] Next, the electric hook electrocoagulation operation is performed, the rotating head 14 is withdrawn, and the electrocoagulation hook 21 is located outside the outer sleeve 15. The rotating head 14 is used to rotate the position of the electrocoagulation hook 21 to accurately align the human body part that needs to be electrocoagulated. Then, the operator uses the foot switch to excite the electrocoagulation energy transmitted through the electrocoagulation energy cable 41 connected to the electrocoagulation energy interface 4 to the electrocoagulation hook 21, thereby completing the electrocoagulation process. Through the flushing button 11 and the negative pressure suction button 12 on the handle 1, the doctor can quickly switch between the flushing and negative pressure suction states without changing the instrument, thereby greatly shortening the operation preparation and operation time. The rotating head 14 allows the doctor to easily push out or withdraw the outer sleeve 15, and adjust the position and angle of the electrocoagulation hook 21. This flexible operation mode simplifies the operation process. Through the adjusting mechanism, the doctor can control the flow of the flushing channel 31 to meet the flushing effect of different operation sites and needs.

[0023] The adjusting mechanism includes an adjusting block 51 fixedly connected to the inner side of the handle 1, and the flushing channel 31 passes through the inside of the adjusting block 51. A long recess is formed on one side of the handle 1, and long grooves are formed on both sides of the inside of the long recess. A long rod is placed in the two long grooves, and the outer side of the long rod is fixedly connected with a toothed block 5 corresponding to the flushing channel 31. First, the adjusting block 51 is fixedly connected to the inner side of the handle 1, which serves as a stable support structure to ensure that the flushing channel 31 can stably pass through its inside. A long recess is formed on one side of the handle 1, which can accommodate half of the toothed block 5. Half of the toothed block 5 is inside the long recess and half is outside. The toothed design of the toothed block 5 is to realize the adjustment of the flow of the flushing channel 31. When the flow needs to be adjusted, the operator can push the toothed block 5 to rotate. When the toothed block 5 rotates, the teeth of the toothed block 5 press the flushing channel 31, which has a certain friction. Therefore, when the toothed block 5 rotates, it will also move upwards towards the top of the handle 1, moving upwards along the direction of the long groove. The long rod is inside the long groove. The further up, the tighter the toothed block 5 presses the flushing channel 31, thereby realizing the flow reduction adjustment. The operator only needs to rotate the toothed block 5 to realize the flow adjustment. This design makes the operation process simple and intuitive, without the need for complex tools or steps, improving the convenience and efficiency of the operation.

[0024] The adjusting block 51 is an oblique block, the upper end of which is close to one side of the toothed block 5, and the lower end of which is away from the other side of the toothed block 5; the adjusting block 51 is obliquely upward, the upper end of which is close to one side of the toothed block 5, and the lower end of which is away from the toothed block 5. During the rotation and movement of the toothed block 5, a dynamic effect of pressing or loosening the flushing channel 31 can be formed with the adjusting block 51, and the degree of pressing of the toothed block 5 on the flushing channel 31 can change with the rotation and movement of the toothed block 5. When the toothed block 5 moves upward, the distance between the toothed block 5 and the adjusting block 51 becomes smaller, and the effective flow area of the flushing channel 31 can be reduced due to the toothed block 5 pressing the flushing channel 31 and generating a certain friction force, so that the flow rate can be reduced. Conversely, when the toothed block 5 moves downward, the flow area of the flushing channel 31 can be increased, and the flow rate can be increased correspondingly.

[0025] The rotating head 14 is attached to the outer side of the positioning block 13, and the outer side of the positioning block 13 is fixedly connected with protrusions at both ends. The rotating head 14 is internally provided with protrusion grooves corresponding to the protrusions. The rotating head 14 mainly has two functions, one is to rotate the rotating head 14 to adjust the position of the electrocoagulation hook 21, and the other is to push the rotating head 14 to make the outer sleeve tube 15 extend. The protrusions are inside the protrusion grooves. When the rotating head 14 is pushed out, the rotating head 14 slides relative to the positioning block 13, that is, the protrusion grooves slide, and the protrusions are stationary, that is, the positioning block 13 is stationary, and the internal cable tube and the electrocoagulation hook 21 are also stationary. When the rotating head 14 is retracted, the rotating head 14 is rotated at this time, that is, the protrusion grooves are rotated, the protrusion grooves press the protrusions, and the protrusions are rotated, that is, the positioning block 13 is rotated, the internal cable tube and the electrocoagulation hook 21 are rotated, the angle of the electrocoagulation hook 21 can be adjusted, and the outer sleeve tube 15 on the outer side is also rotated simultaneously. By integrating multiple functions in the rotating head 14 and matching stable sliding and rotating mechanisms, the operation efficiency and convenience of the surgical instrument are improved.

[0026] The cable tube and the positioning block 13 are fixedly connected, the electrocoagulation hook 21 and the cable tube are fixedly connected, the cable and the electrocoagulation hook 21 are connected, and the handle 1 and the positioning block 13 are rotationally connected. The cable tube and the positioning block 13 are fixedly connected, the electrocoagulation hook 21 and the cable tube are fixedly connected, so that the rotation of the positioning block 13 can be accompanied by the rotation of the electrocoagulation hook 21, the cable 41 and the electrocoagulation hook 21 are connected together, and thus the energy transmission is completed. The handle 1 and the positioning block 13 are rotationally connected, so that the positioning block 13 can rotate with the rotation of the rotating head 14.

[0027] The rotating head 14 and the outer sleeve tube 15 are fixedly connected. In this way, when the rotating head 14 is pushed out, the outer sleeve tube 15 will be pushed out at the same time, and the stability during operation is also ensured.

[0028] The outer surface of the handle 1 is provided with an anti-skid texture, and the material of the electric coagulation hook 21 is titanium alloy; the anti-skid texture can increase the friction between the handle 1 and the operator's hand, and ensure the stability and safety of operation. The titanium alloy has good corrosion resistance and can maintain stable performance for a long time in the surgical environment.
