Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a deep bipolar electric knife for fine dissection with adaptable angle adjustment. Background Art

[0002] With the rapid development of minimally invasive surgery, there are more and more scenarios for detailed dissection of deep tissue. For example, endoscopic combined oral and nasal approach resection is a common procedure for skull base tumors. However, the surgical field is close to the internal carotid artery. Traditional sharp separation techniques have poor hemostasis effects, high operational risks, and long separation times. Although monopolar electrocoagulation separation can effectively separate tissue, the heat energy it generates can easily damage blood vessels, leading to vascular spasm and occlusion, and in the most serious case, it can cause massive bleeding. Therefore, in areas close to the internal carotid artery, when using monopolar electrocoagulation, separation often needs to be performed at a distance from the target vessel. This results in a large amount of soft tissue remaining around the blood vessels, affecting the tumor resection rate.

[0003] In contrast, bipolar electrocoagulation separation cauterizes tissue at low power to seal blood vessels and stop bleeding, offering improved safety. At high power, bipolar coagulation can achieve cutting and separation. Although conventional wisdom holds that bipolar coagulation can only separate a limited amount of tissue at a time and requires a long time to complete, when separating nasopharyngeal carcinoma tissue, the tissue surrounding blood vessels is often sparse, with loose connective tissue predominating. This provides favorable conditions for bipolar electrocoagulation separation. Bipolar electrocoagulation separation has potential advantages in nasopharyngeal carcinoma surgery, particularly for cutting and separating tissue near the internal carotid artery.

[0004] However, there are currently no bipolar endoscopes suitable for ENT surgery, especially for transoral use, as the catheter needs to bend, and traditional bipolar coagulation technology is difficult to meet this requirement. Therefore, bipolar coagulation can provide safer and more effective cutting and separation solutions through improved design and the development of new endoscopes, thereby improving the success rate of nasopharyngeal carcinoma surgery and the quality of life of patients.

[0031] See also Figure 13 Each blade body assembly is embedded with an inner knife mechanism 6, and the inner knife mechanism 6 includes an inner knife 601 adapted to be inserted into the first inner groove 402, and the tail end of the inner knife 601 is fixedly connected to a strip bag 602 adapted to be inserted into the second inner groove 403, and the tail end of the strip bag 602 is fixedly connected to a first air pipe 603, and the first air pipe 603 is adapted to be inserted into the second inner groove 403 and the connecting pipe 404, and the tail end of the first air pipe 603 passes through the column shaft 405 and the arc piece 201 and is fixedly connected to the second air pipe 604 embedded in the handle body 101, and the tail end of the second air pipe 604 passes through the handle 102 and is installed with an air pump 605 fixedly connected to the handle 102.

[0032] See also Figure 6 A net bag 7 is fixedly connected between the electric knives 401 of the two blade body assemblies.

[0033] The working principle of the present invention is as follows: The head end of the electric knife 401 is upturned in the shape of a quarter circle. After the medical staff holds the knife handle mechanism 1 and sends the knife head assembly into the patient's pharynx, the curved outer wall of the electric knife 401 is in direct contact with the patient's pharynx. When the knife head assembly is inserted into the patient's pharynx, the electric knife 401 gently contacts the patient's pharynx, improving the patient's comfort.

[0034] By inserting the inner blade 601 inside the electric knife 401 and controlling the amount of gas introduced into the strip capsule 602 through the air pump 605, the strip capsule 602 is expanded to different lengths, and the inner blade 601 is extended to different lengths from the electric knife 401. After the blade head assembly is inserted into the patient's pharynx, the head end position of the inner blade 601 can be adjusted according to the actual surgical situation, thereby improving the adaptive deployment performance during use.

[0035] The inner knife 601 is inserted into the electric knife 401 in a retractable manner. When inserted into the patient's mouth, the inner knife 601 can be completely retracted into the electric knife 401. The head end of the electric knife 401 is upturned into a quarter-circle arc shape, so that it can be easily inserted into the patient's recess, improving the convenience of insertion.

[0036] After the blade head assembly is inserted into the patient's crypt when the inner blade 601 is in the retracted state, the cavity inside the crypt is larger than the cavity entering the crypt opening. At this time, the inner blade 601 can be extended to an appropriate length as needed. The electric knife 401 and the inner blade 601 are in a matching arc shape, so that the blade head assembly can fit the crypt wall more cleverly, thereby effectively and comprehensively treating the patient.

[0037] The medical staff simultaneously pulls the finger ring 503 from the outside, pulls the second pull rope 502 from the outside and then pulls the first pull rope 408, and manipulates different blade assemblies through the pull rope assembly. At the same time, when pulling the first pull rope 408, the blade assemblies placed in a V shape on both sides are brought closer to each other, thereby clamping the affected tissue to stop bleeding or perform excision treatment. By operating the blade assembly from the outside, the convenience of use is improved.

[0038] By setting the net bag 7, when the affected tissue is removed by the electric knife mechanism 4, the fallen tissue blocks can be directly received by the net bag 7, avoiding the tissue blocks from slipping out of the oral cavity and causing danger to the patient, thereby improving the safety of use.

[0039] A first pull rope 408 is fixedly connected to a column block 407 on the pull rope assembly, and the first pull rope 408 passes through another column block 407, so that the first pull rope 408 starts from one column block 407 and then goes around the other column block 407 and is pulled out. Therefore, when only one finger ring assembly is pulled, the entire blade assembly can be pulled, so that the airbag 305 is squeezed and dislocated from the flower shape of the shaft groove 203, so that the blade assembly can be driven to rotate in the patient's recess with the joint mechanism 2 as the axis, so that the tissue on the side wall of the recess can also be processed, thereby improving the flexibility of surgical treatment.

[0040] When the blade head assembly is deflected, the positions of the second pull rope 502 and the finger ring assembly are synchronously offset, and there may be a problem that the position of the finger ring assembly is inconvenient for medical staff to operate. By manually pressing the pressure column 506, the medical staff can keep the second pull rope 502 flush at the connection between the pressure column 506 and the rope ring 504, that is, the holes on the pressure column 506 and the rope ring 504 corresponding to the second pull rope 502 are aligned. At this time, the finger ring assembly can be adjusted to the appropriate position accordingly to improve the operating comfort of medical staff.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
