Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, specifically to a deep bipolar electrosurgical unit for precision anatomy with an adjustable angle. Background Technology
[0002] With the rapid development of minimally invasive surgery, there are increasingly more complex anatomical scenarios involving deep tissues. For example, endoscopic oronasal resection is a common procedure for skull base tumors. However, the surgical field in this procedure is close to the internal carotid artery, making traditional sharp dissection techniques ineffective for hemostasis, risky, and time-consuming. While monopolar electrocoagulation can efficiently separate tissue, the heat it generates can easily damage blood vessels, leading to vasospasm and occlusion, and in the most serious cases, massive hemorrhage. Therefore, when using monopolar electrocoagulation near the internal carotid artery, dissection often needs to be performed at a greater distance from the target vessel. This results in more soft tissue remaining around the vessel, affecting the tumor resection rate.
[0003] In comparison, bipolar electrocoagulation dissection, by cauterizing tissue at low power to seal blood vessels and stop bleeding, offers better safety. At high power, bipolar electrocoagulation can achieve cutting and dissection. Although traditionally it is believed that bipolar electrocoagulation can only separate a limited amount of tissue in a single procedure and requires a longer time to complete, in the dissection of nasopharyngeal carcinoma tissue, the tissue encasing blood vessels is often less, consisting mainly of loose connective tissue, which provides favorable conditions for bipolar electrocoagulation dissection. Bipolar electrocoagulation dissection has potential advantages in nasopharyngeal carcinoma surgery, especially in the cutting and dissection of tissue near the internal carotid artery.
[0004] However, there are currently no suitable bipolar catheters for otolaryngology, especially transoral bipolar catheters, in which the catheter needs to bend, a requirement that traditional bipolar electrocoagulation techniques cannot meet. Therefore, bipolar electrocoagulation, through improved design and the development of new endoscopes, can provide safer and more effective cutting and dissection solutions, thereby improving the success rate of nasopharyngeal carcinoma surgery and patients' quality of life.

[0025] Compared with the prior art, the beneficial effects of the present invention are:
[0026] The conformally adjustable, precision anatomical deep bipolar electrosurgical unit features an arc-shaped outer wall that makes direct contact with the patient's pharynx. When the tip assembly is inserted into the patient's pharynx, the electrosurgical unit gently contacts the pharynx, improving patient comfort.
[0027] The shape-adjustable angle deep bipolar electrosurgical unit for precise dissection allows for adjustment of the tip position of the inner blade according to the actual surgical situation, improving its adaptive adjustment performance during use.
[0028] This is a deep bipolar electrosurgical unit for precise dissection with an adjustable angle. The inner blade is inserted into the electrosurgical unit in a retractable manner. When inserted into the patient's oral cavity, the inner blade can be completely retracted into the electrosurgical unit. The tip of the electrosurgical unit is curved upwards in a quarter-circle shape, which makes it easy to insert into the patient's crypt, improving the ease of insertion.
[0029] The contour-adjustable, angle-adjustable deep bipolar electrosurgical unit for precise anatomy uses an arc-shaped electrosurgical unit and an inner blade that fit together to allow the tip assembly to fit snugly against the crypt wall, thus providing effective and comprehensive treatment for the patient.
[0030] This contour-adjustable, angle-adjustable deep bipolar electrosurgical unit for precise dissection uses a V-shaped blade assembly placed on both sides to clamp the affected tissue for hemostasis or excision. The unit's external manipulation enhances ease of use.
[0031] The contour-adjustable, angle-adjustable deep bipolar electrosurgical unit for precise dissection uses a net to catch any falling tissue fragments during the removal of tissue from the affected area. This prevents tissue fragments from slipping out of the mouth and posing a risk to the patient, thus improving safety.
[0032] The conformally adjustable, finely anatomically precise bipolar electrosurgical unit can rotate the blade assembly within the patient's crypt using the connector mechanism as an axis, thereby enabling the treatment of tissues on the lateral walls of the crypt and improving the flexibility of surgical procedures.
[0033] The conformally adjustable deep bipolar electrosurgical unit for precise dissection allows medical staff to manually press the pressure post, ensuring the second pull cord remains flush at the connection between the pressure post and the cord loop. This means the holes on the pressure post and the cord loop corresponding to the second pull cord are aligned. At this point, the finger ring assembly can be adjusted to a suitable position, improving the operating comfort of medical staff. Attached Figure Description

The tail end of the first air tube 603 passes through the column shaft 405 and the arc plate 201 and is fixedly connected to a second air tube 604 embedded inside the handle 101. The tail end of the second air tube 604 passes through the grip 102 and is fitted with an air pump 605 fixedly connected to the grip 102.
[0068] Please see Figure 6 A net bag 7 is fixedly connected between the two blade assemblies of the electric knife 401.
[0069] The working principle of this invention is as follows:
[0070] The tip of the electrosurgical unit 401 is curved upwards in a quarter-circle shape. After the medical staff holds the handle mechanism 1 and inserts the blade assembly into the patient's pharynx, the curved outer wall of the electrosurgical unit 401 directly contacts the patient's pharynx. When the blade assembly is inserted into the patient's pharynx, the electrosurgical unit 401 gently contacts the patient's pharynx, improving the patient's comfort.
[0071] By inserting an inner blade 601 inside the electrosurgical unit 401 and controlling the amount of gas introduced into the balloon 602 via the air pump 605, the balloon 602 expands to different lengths, thereby causing the inner blade 601 to extend out of the electrosurgical unit 401 to different lengths. After the blade assembly is inserted into the patient's pharynx, the position of the tip of the inner blade 601 can be adjusted according to the actual surgical situation, improving the adaptive adjustment performance during use.
[0072] The inner blade 601 is inserted into the electrosurgical knife 401 in a retractable form. When inserted into the patient's oral cavity, the inner blade 601 can be completely retracted into the electrosurgical knife 401. The tip of the electrosurgical knife 401 is curved upward in a quarter-circle shape, which makes it easy to insert into the patient's crypt, improving the ease of insertion.
[0073] When the inner blade 601 is in the retracted state, the blade assembly is inserted into the patient's crypt. The cavity inside the crypt is larger than the cavity at the crypt opening. At this time, the inner blade 601 can be extended to an appropriate length as needed. With the electrosurgical unit 401 and the inner blade 601 forming a matching arc shape, the blade assembly can fit the crypt wall more cleverly, thereby effectively and comprehensively treating the patient.
[0074] Medical staff can simultaneously pull the ring 503 from the outside, and then pull the first pull rope 408 by pulling the second pull rope 502. By pulling the rope assembly, different blade components can be manipulated. At the same time, pulling the first pull rope 408 will bring the blade components placed in a V-shape on both sides closer together, thereby clamping the affected tissue to stop bleeding or perform excision. By operating the blade components from the outside, the ease of use is improved.
[0075] With the net bag 7 in place, when the electrosurgical mechanism 4 removes tissue from the affected area, the falling tissue pieces can be directly caught by the net bag 7, preventing the tissue pieces from slipping out of the mouth and causing danger to the patient, thus improving the safety of use.
[0076] A first pull rope 408 is fixedly connected to a column 407 on the pull rope assembly. The first pull rope 408 passes through another column 407, so that the first pull rope 408 starts from one column 407, goes around the other column 407 and is pulled out. Therefore, when only one ring assembly is pulled, the entire blade assembly can be pulled, so that the air bladder 305 is squeezed out of the flower shape of the shaft groove 203 and misaligned. This allows the blade assembly to rotate in the patient's crypt with the connector mechanism 2 as the axis, and can also treat the tissue on the side wall of the crypt, improving the flexibility of surgical treatment.
[0077] When the blade assembly deflects, the positions of the second pull cord 502 and the ring assembly shift synchronously. There may be a problem that the position of the ring assembly is inconvenient for medical staff to operate. By having medical staff manually press the pressure post 506, the second pull cord 502 can be kept flush at the connection between the pressure post 506 and the cord ring 504, that is, the holes on the pressure post 506 and the cord ring 504 corresponding to the second pull cord 502 are aligned. At this time, the ring assembly can be adjusted to a suitable position to improve the operating comfort of medical staff.
[0078] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
