Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a bipolar electrocoagulation dripping speed regulating device. Background Art

[0002] Bipolar coagulation is a commonly used hemostatic device during neurosurgery. Its working principle is to achieve hemostasis by cauterizing bleeding tissue and blood vessel stumps through the mutual discharge between the positive and negative terminals of the bipolar coagulator. During hemostasis, saline drips from the tip of the bipolar coagulator, moistening the tip and significantly reducing tissue adhesions. The bipolar coagulator can also be used as a standard forceps to grasp objects during surgery.

[0003] Whether or not a bipolar coagulator drips water, and the dripping speed, significantly impacts the surgical process. For example, when coagulating small intracranial vessels and surrounding structures, a slow dripping rate can easily cause adhesions between brain tissue and the forceps tip. A fast dripping rate can obscure the surgical field or ineffectively stop bleeding. When used as standard forceps, continued dripping can contaminate the instrument. Therefore, the surgeon must decide whether to allow the bipolar coagulator to drip water based on personal experience and the surgical procedure, and precisely control the dripping rate.

[0004] The existing bipolar electrocoagulation designs all consider how to more precisely control the dripping speed of bipolar electrocoagulation, such as the design of single-channel and dual-channel drip tubes, and the design of precise flow rate regulation water delivery devices, etc. However, these designs are often complex in structure and cumbersome to control, and do not consider how to enable the surgeon to achieve real-time autonomous control without affecting the progress of the operation and increasing various potential surgical risks during the operation. Based on this, the surgeon can only stop the operation himself or notify the assistant to manually adjust the drip switch and drip speed, which will not only distract the surgeon's attention, but also the assistant's understanding of the control of the dripping speed may differ from that of the surgeon, thus affecting the progress of the operation and possibly increasing various potential surgical risks during the operation.

DETAILED DESCRIPTION

[0027] The specific embodiments of the present invention will be described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0028] Reference Figure 1The present invention provides a bipolar electrocoagulation dripping speed regulating device, comprising a bipolar electrocoagulation device 1, a venous drip tube 2, a flow rate regulating mechanism 3, a foot-operated inflation mechanism 4, and a foot-operated deflation mechanism 5. The venous drip tube 2 is used to transport physiological saline in an injection solution packaging bag 6 into the bipolar electrocoagulation device 1. During surgery, the physiological saline drips out through the tip of the forceps of the bipolar electrocoagulation device 1, thereby moistening the tip of the forceps. The flow rate regulating mechanism 3 comprises a housing 31, a pressure wheel 32, and an air bag 33 disposed within the housing 31. The housing 31 is provided with a passage for the venous drip tube 2 to pass through, and is provided with a track 311 arranged parallel to the passage. The air bag 33 is used to drive the pressure wheel 32 to slide along the track 311, thereby adjusting the pressure between the pressure wheel 32 and the venous drip tube 2. The foot-operated inflation mechanism 4 and the foot-operated deflation mechanism 5 are connected to the air bag 33 via an air inlet pipe 331 and an air outlet pipe 332, respectively. During operation, the surgeon can adjust the air pressure in the airbag 33 by pedaling the inflation mechanism 4 and the deflation mechanism 5, causing the airbag 33 to expand or contract, thereby driving the pressure wheel 32 to slide along the track 311, causing the pressure between the pressure wheel 32 and the static dropper 2 to change, thereby achieving real-time regulation of the drip switch and the drip speed. It can be seen that the bipolar electrocoagulation drip speed adjustment device provided by the utility model is not only simple in structure but also easy to operate. The surgeon can independently complete the real-time and precise regulation of the drip switch and the drip speed without affecting the progress of the operation, thereby overcoming the problems existing in the prior art.

[0029] Reference Figures 1 to 4 The upper and lower ends of the shell 31 are provided with clearance holes 312 for the static drip tube 2 to pass through, and the front and rear side walls of the shell 31 are provided with tracks 311. In this embodiment, the left side wall of the shell 31 is in an arc shape that gradually expands from top to bottom. The two clearance holes 312 above and below the shell 31 and the internal cavity of the shell 31 located on the left side of the track 311 together constitute a channel for installing the static drip tube 2. The pressure wheel 32 includes a pressure wheel body 321 and a connecting shaft 322. The pressure wheel body 321 is slidably arranged on the track 311 via the connecting shaft 322. The left side wall of the pressure wheel body 321 abuts against the static drip tube 2, and the bottom of the pressure wheel body 321 abuts against the airbag 33. Specifically, during the expansion process, the airbag 33 will exert an upward squeezing force on the pressure wheel 32, causing the pressure wheel 32 to slide upward along the track 311, thereby increasing the pressure between the pressure wheel 32 and the static dropper 2, thereby reducing the dripping speed of the static dropper 2 or causing the static dropper 2 to completely stop dripping; during the contraction process of the airbag 33, the squeezing force exerted on the pressure wheel 32 gradually decreases, causing the pressure wheel 32 to slide downward along the track 311 under its own gravity, thereby reducing the pressure between the pressure wheel 32 and the static dropper 2, thereby opening the static dropper 2 and increasing the dripping speed of the static dropper 2.

[0030] Reference Figure 3 and Figure 4Preferably, the airbag 33 has a columnar structure, with its upper and lower ends abutting against the pressure roller 32 and the housing 31, respectively. The housing 31 has mounting holes 313 at the bottom for the air inlet pipe 331 and the air outlet pipe 332 to pass through. Mounting holes for the air inlet pipe 331 and the air outlet pipe 332 are also provided at the bottom of the airbag 33. Both mounting holes are fitted with a first one-way diaphragm (not shown). This first one-way diaphragm ensures that air can only flow in and out of the airbag 33 in one direction, through the air inlet pipe 331 and the air outlet pipe 332, respectively, thereby ensuring a stable and reliable structure.

[0031] Reference Figure 2 Preferably, the housing 31 includes a first housing 314 and a second housing 315 that are detachably connected. The inner sidewalls of the first housing 314 and the second housing 315 protrude outward to form a track 311. The first housing 314 and the second housing 315 can be detachably connected by a snap-fit ​​connection or a bolt connection, which is not limited here. Designing the housing 31 as a detachable structure facilitates the assembly of the pressure wheel 32 and the airbag 33, and facilitates subsequent maintenance and inspection, resulting in a more reasonable design.

[0032] Reference Figure 1 and Figure 5 The foot-operated inflation mechanism 4 includes an air pump 41, a base plate 42, and a foot pedal 43 disposed at both ends of the air pump 41. The foot pedal 43 is provided with an inflation port 431 and an air intake port 432 connected to the air pump 41, and the air inlet pipe 331 is connected to the inflation port 431. When it is necessary to inflate the airbag 33, air from the external environment can be sucked into the air pump 41 through the air intake port 432 by stepping on the air pump 41, and then sucked into the airbag 33 through the air intake pipe 331. The operation is simple and convenient. It should be noted that the internal structure of the air pump 41 belongs to the prior art. Those skilled in the art can make a reasonable design based on the above description and the prior art, and will not be elaborated here. Similarly, to ensure that the air pump 41 can achieve one-way suction and one-way inflation, a second one-way diaphragm 433 is provided in both the air intake port 432 and the inflation port 431. Of course, in actual applications, one-way valves of other structures can also be used.

[0033] Reference Figure 1 、 Figure 6 and Figure 7The foot-operated deflation mechanism 5 includes a first plate 51 and a second plate 52. The first plate 51 is hingedly connected to the second plate 52 via a hinge 53 and a torsion spring (not shown). The outlet pipe 332 is clamped between the first and second plates 51, 52, and the end of the outlet pipe 332 is secured to the second plate 52 via a connector 54. The connector 54 of the outlet pipe 332 can be a clamp or a buckle, or other easily removable component, without limitation. When the air in the airbag 33 needs to be discharged, the first plate 51 can be stepped on to control the opening between the first and second plates 51, 52, thereby opening the outlet pipe 332 and allowing the air in the airbag 33 to be discharged outward through the outlet pipe 332. Because the torsion springs are provided between the first and second plates 51, releasing the first plate 51 automatically resets it, thereby reclosing the outlet pipe 332. By adjusting the pedaling force of the foot, the opening between the first and second clamping plates 51, 52 can be precisely controlled, thereby precisely adjusting the exhaust speed and exhaust volume of the outlet pipe 332, making operation more reasonable and convenient. Similarly, to ensure that the outlet pipe 332 can achieve one-way exhaust, a third one-way diaphragm is also installed at the end of the outlet pipe 332.

[0034] Reference Figure 1 , the bipolar electrocoagulation dripping speed regulating device infusion pressurized bag 7, the injection liquid packaging bag 6 is arranged in the infusion pressurized bag 7. The function of the infusion pressurized bag 7 is to provide pressure for the injection liquid packaging bag 6, thereby increasing the dripping speed. Its structure and principle belong to the existing technology and are not described here. In actual application, the infusion pressurized bag 7 can cooperate with the flow rate regulating mechanism 3, thereby helping the leading doctor to more accurately control the dripping speed. However, if the dripping speed can be controlled within the ideal range by the flow rate regulating mechanism 3, there is no need to set the infusion pressurized bag 7.

[0035] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
