Description

Technical Field

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

[0002] Electrocoagulation forceps is an instrument widely used in the medical field, especially in surgical operations. Electrocoagulation forceps are usually composed of a forceps body, a forceps tip, a conductive part, a suction part, and a flow-conducting part. The electrocoagulation forceps conduct the current to the forceps tip by connecting to the electrosurgical device. During the operation, when the forceps tip touches the tissue, the current passes through the tissue to produce a thermal effect, causing the tissue to coagulate and stop bleeding. Depending on the different surgical requirements, the size and type of current can be adjusted to achieve different degrees of coagulation effect. For example, low-power current can be used for delicate hemostasis operations, while high-power current can be used for coagulation of larger blood vessels.

[0003] A modular bipolar electrocoagulation forceps is disclosed in the patent publication number CN219306911U. The electrocoagulation forceps include 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. 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 pipe that is connected to the hollow tube and passes through the electrode rod. The liquid inlet pipe is used to connect the liquid inlet assembly. The conductive sheet, the connection part between the conductive sheet and the electrode rod, and the part where the liquid inlet pipe 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 batch-produce the subassemblies of the electrocoagulation forceps, and then assemble them according to different surgical needs, thereby improving production efficiency and production quality.

[0004] The prior art 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. 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 cleaning and cooling role. 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 surgical process complicated and increases the difficulty of the operation. Summary of the invention

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

[0051] By setting the control component 6, when the shunt 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 performed simultaneously, and the inner core 69 is rotated to adjust the suction docking port 614 and the input port 67.

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

[0059] A binding assembly 8 is disposed on the outer side 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 forceps arm 1, a threaded sleeve 82 disposed inside the threaded interface 81, a binding rope 83 disposed at a side of the threaded sleeve 82 away from the top sleeve 71, and a fixing ring 84 disposed at an 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 assembly 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 sleeved 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 1-2, 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 line 41 are inserted from the opening below the top sleeve 71 and come out from 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. 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 pipeline 52 and the plug connector 42, connect the power cord 41 to the power supply equipment, and then insert the guide pipelines 52 into the output interface 68 one by one, and then conveniently insert the flushing tube 54 and the suction tube 53 into the input interface 67, and connect the other ends of the flushing tube 54 and the suction tube 53 to the cleaning liquid supply equipment and the smoke suction equipment respectively, and finally slide the fixing ring 84 along the guide pipeline 52 and the power cord 41 to make the fixing ring 84 continue 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 pipeline 52 and the power cord 41.

[0066] During use, when suction work is required, the knob 619 is turned, and the knob 619 drives the adjusting inner core 69 to rotate, so that the suction interface 614 is connected to the input interface 67. At this time, the diversion interface 613 and the flushing interface 615 are misaligned with the input interface 67, and only the outer puzzle plate 63 can act on the connecting inner groove 611. The movable interface 616 is connected to 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 to the output interface 68. Fig.12 As shown, the two connected inner grooves 611 are affected by the outer puzzle plate 63, generating attraction, thereby causing the four guide pipes 52 to generate attraction, and the attraction finally acts on the tip of the forceps 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 are required at the same time, turn the rotating knob 619, and the rotating knob 619 drives the adjusting inner core 69 to rotate, so that the two diversion interfaces 613 are docked with the input interface 67. At this time, the flushing interface 615 and the suction interface 614 are both misaligned with the input interface 67, and the movable interface 616 is also misaligned with the fixed interface 617. The wide interface 612 is always connected with the output interface 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 rather than to limit it. 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.
