Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a multifunctional surgical dissection system with adjustable positive and negative pressures and suction and flushing. Background Art

[0002] Electrocoagulation forceps are an instrument widely used in the medical field, especially in surgical procedures. They typically consist of a body, a tip, a conductive portion, a suction portion, and a flow-conducting portion. The forceps are connected to an electrosurgical device to conduct current to the tip. During surgery, when the tip contacts tissue, the current passes through the tissue, generating a thermal effect that coagulates the tissue and stops bleeding. Depending on the surgical requirements, the magnitude and type of current can be adjusted to achieve varying degrees of coagulation. For example, low-power current can be used for delicate hemostasis procedures, while high-power current can be used to coagulate larger blood vessels.

[0003] Patent publication number CN219306911U discloses a modular bipolar electrocoagulation forceps, which includes two conductive sheets, two electrode rods, two electrode heads, two handles, and a forceps handle seat. The tail ends of the two conductive sheets are respectively arranged on the forceps handle seat. The front end of each conductive sheet is conductively connected to the electrode rod, and the front end of each electrode rod is conductively connected to the electrode head. At least one of the electrode rods has a hollow tube built in. At least one of the electrode heads has a liquid outlet at the front end that is connected to the hollow tube in the electrode rod. At least one of the electrode rods is provided with a liquid inlet tube that is connected to the hollow tube and passes through the electrode rod. The liquid inlet tube is used to connect the liquid inlet assembly. The conductive sheet, the connection between the conductive sheet and the electrode rod, and the portion where the liquid inlet tube passes through the electrode rod are wrapped by injection molding to form a handle. The modular bipolar electrocoagulation forceps provided by the utility model modularize and mass-produce the subassemblies of the electrocoagulation forceps, and then assemble them according to the needs of different surgical operations, thereby improving production efficiency and production quality.

[0004] The existing technology has the following defects:

[0005] When using electrocoagulation forceps, the conductive part, the suction part, and the diversion part need to work together. The conductive part is controlled by the opening and closing of the electrocoagulation forceps to stop bleeding by electrocoagulation. Then the suction part absorbs the smoke generated during the electrocoagulation hemostasis process. The diversion part drains water at the tip of the forceps to play a role in cleaning and cooling. However, since the suction part and the diversion part are two different units and the status of the suction part and the diversion part need to be constantly adjusted as the operation progresses, this makes the operation process complicated and increases the difficulty of the operation. Summary of the Invention

[0006] In view of the problem of complex operation in the existing technology, a multifunctional surgical dissection system with adjustable positive and negative pressure suction and flushing is proposed.

The fixed docking port 617 and the two movable docking ports 616 are all located on the same annular contour.

[0051] By setting the control component 6, when the diverter docking port 613 is docked with the input port 67, the suction tube 53 and the flushing tube 54 are respectively connected to the two guide pipes 52, so that suction and cleaning work can be carried out simultaneously. The inner core 69 is rotated to adjust the suction docking port 614 to dock with the input port 67, and the suction tube 53 is connected to the four guide pipes 52, and only suction work is performed.

[0056] Example 2, reference Figure 14-16 , which is the second embodiment of the present invention, differs from the first embodiment in that: a support assembly 7 is provided on the outside of the mounting joint 3, and the support assembly 7 specifically includes a top sleeve 71 sleeved on the outside of the mounting joint 3, and an extension arm 72 provided on the outside of the top sleeve 71;

[0057] Specifically, the top sleeve 71 is made of rubber, which is sleeved on the outside of the mounting joint 3 and fixed to the mounting joint 3 by its own elastic contraction force and friction. The extension arm 72 and the top sleeve 71 are integrally formed, and the connection between the extension arm 72 and the top sleeve 71 adopts an arc-shaped design. The end of the extension arm 72 away from the top sleeve 71 is provided with a bend in the direction of the guide seat 2.

[0058] By setting up the support component 7, when in use, the operator holds the forceps arm 1 with his fingers, and the extended arm 72 is overlapped at the base of the thumb. This can make the operator's grip on the forceps arm 1 more stable, and make it more convenient and easy to use, which plays a certain role in ensuring the smooth progress of the operation.

[0059] A binding assembly 8 is provided on the outside of the support assembly 7. The binding assembly 8 specifically includes a threaded interface 81 provided at the end of the top sleeve 71 away from the tweezers arm 1, a threaded sleeve 82 provided inside the threaded interface 81, a binding rope 83 provided on the side of the threaded sleeve 82 away from the top sleeve 71, and a fixing ring 84 provided on the end of the binding rope 83 away from the threaded sleeve 82;

[0060] Specifically, the guide channel 51 and the power cord 41 pass through the threaded interface 81, the threaded sleeve 82, the binding rope 83 and the fixing ring 84. The threaded sleeve 82 is provided with an external thread and is fixed to the threaded interface 81 through the external thread. The threaded sleeve 82 and the fixing ring 84 are fixed to the two ends of the binding rope 83 by glue. The binding rope 83 is spirally designed and made of elastic material. An elastic rubber ring is installed on the inner side of the fixing ring 84, and the guide pipeline 52 and the power cord 41 are bound to the inside by the elastic rubber ring fixing ring 84.

[0061] By setting up the binding component 8, after the connection of various lines is completed, the fixing ring 84 is dragged along the guide pipe 52 and the power cord 41 to pull out the binding rope 83. The binding rope 83 is set on the outside of the guide pipe 52 and the power cord 41 to bind the two and avoid the situation where too many lines are entangled with each other during the operation.

[0062] Based on Examples 1 and 2, the working principle of the positive and negative pressure adjustable suction and flushing multifunctional surgical dissection system of the present invention is as follows:

[0063] During installation, the guide pipe 52 and the power cord 41 are passed through the opening below the top sleeve 71 and out of the threaded interface 81 , and then passed through the threaded sleeve 82 , the binding rope 83 and the fixing ring 84 in sequence, and finally the threaded sleeve 82 is screwed into the threaded interface 81 .

[0064] Place the adjustment inner core 69 into the assembly inner groove 65 on the outer panel 63. During this process, keep the diversion interface 613 aligned with the input interface 67. Then put the inner panel 64 on top of the outer panel 63 and fix it with bolts. Then place the outer panel 63 and the inner panel 64 into the outer shell 61, and then snap the sealing cover 62 onto the surface of the outer shell 61. Finally, insert the rotating knob 619 from the slot 618.

[0065] Pull and separate the guide pipe 52 and the plug connector 42, connect the power cord 41 to the power supply equipment, and then insert the guide pipes 52 into the output interface 68 one by one, and then conveniently insert the flushing pipe 54 and the suction pipe 53 into the input interface 67, and connect the other ends of the flushing pipe 54 and the suction pipe 53 to the cleaning liquid supply equipment and the smoke suction equipment respectively. Finally, slide the fixing ring 84 along the guide pipe 52 and the power cord 41, so that the fixing ring 84 continues to approach the plug connector 42 and the control component 6 until it is blocked by one of the components and stops, and the binding rope 83 is wrapped around the outside of the guide pipe 52 and the power cord 41.

[0066] During use, when suction is required, the knob 619 is turned, and the knob 619 drives the regulating inner core 69 to rotate, so that the suction interface 614 is docked with the input interface 67. At this time, the diversion interface 613 and the flushing interface 615 are both misaligned with the input interface 67, and only the outer panel 63 can act on the connecting inner groove 611. The movable interface 616 is docked with the fixed interface 617, and the fixed interface 617 connects the connecting inner grooves 611 on both sides, and the wide interface 612 is always connected with the output interface 68. Figure 12 As shown, the two connected inner grooves 611 are affected by the outer panel 63, generating attraction, thereby causing the four guide pipes 52 to generate attraction, and the attraction eventually acts on the tip of the tweezers arm 1 through the guide channel 51 to complete the smoke suction work.

[0067] When flushing is required, turn the rotating knob 619, and the rotating knob 619 drives the adjusting inner core 69 to rotate, so that the flushing docking port 615 is docked with the input interface 67. At this time, the diversion docking port 613 and the suction docking port 614 are both misaligned with the input interface 67, and only the inner puzzle plate 64 can act on the connecting inner groove 611. Another movable docking port 616 is docked with the fixed docking port 617. The fixed docking port 617 connects the connecting inner grooves 611 on both sides, and the wide docking port 612 is always connected to the output interface 68. In this way, the two connecting inner grooves 611 are affected by the inner puzzle plate 64, and the cleaning liquid flows into them, and then flows into the four guide pipes 52, and finally is discharged to the tweezers tip part of the tweezers arm 1 through the guide channel 51 to complete the flushing work.

[0068] When flushing and suction work needs to be performed simultaneously, turn the rotating knob 619, and the rotating knob 619 drives the adjusting inner core 69 to rotate, so that the two diversion docking ports 613 are docked with the input port 67. At this time, the flushing docking port 615 and the suction docking port 614 are both misaligned with the input port 67, and the movable docking port 616 is also misaligned with the fixed docking port 617. The wide docking port 612 is always connected with the output port 68. In this way, the two connected inner grooves 611 are respectively affected by the outer puzzle plate 63 and the inner puzzle plate 64, one generates attraction, and the other is injected with clear cleaning liquid. At the same time, the two connected inner grooves 611 respectively control the two guide pipes 52, so that part of the guide channel 51 attracts smoke and part of the guide channel 51 discharges cleaning liquid.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
