Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a deep monopolar electrosurgical unit with an adjustable angle. Background Technology

[0002] With continuous advancements in surgical techniques, the application of small incisions or deep surgeries using natural cavities is becoming increasingly widespread. For example, endoscopic oronasal resection of skull base tumors is a common procedure. 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. Monopolar electrocoagulation can efficiently dissect tissue, but traditional electrocautery devices have limited mobility in endoscopically guided narrow cavities. Therefore, in complex cavities, traditional monopolar electrocoagulation often requires dissection at a considerable distance from the target, resulting in more residual tissue, affecting tumor resection rates, increasing surgical time, and indirectly increasing potential surgical risks.

[0003] Currently, there are no suitable electrocoagulation monopolar devices for deep incisions, especially transoral electrocoagulation monopolar devices, where the catheter needs to bend, a requirement that traditional electrocoagulation monopolar devices cannot meet. This invention aims to provide a safer and more effective cutting and dissection solution through the development of a novel electrocoagulation monopolar device, thereby improving the success rate of nasopharyngeal carcinoma surgery and the quality of life for patients. Summary of the Invention

The circulating water enters between the inner and outer capsules through the pipes to cool the area around the affected area. The cooling effect of the balloon mechanism can solve the problem of damage caused by the blade being too close to the wound. The flow of circulating water allows the blade to get closer to the wound, improving the precision of the surgery. Attached Figure Description

Three first lens tubes 304 facing the central axis are fixedly connected at equal intervals on the upper surface of the arc strip 303. The first lens tube 304 in the middle is used for observation, and the other first lens tubes 304 are used for illumination. A vertical rod 305 is fixedly connected to the lower surface of the arc strip 303. The lower end of the vertical rod 305 is embedded in the second support post 301 and connected to the second support post 301 through a cylinder. Initially, the arc strip 303 is attached to the upper end of the first support post 201.

[0076] A retaining ring 302 is fixedly sleeved on the upper outer side of the second column 301.

[0077] The outer side of the cutter head assembly is wrapped with a balloon mechanism 4;

The retaining ring 202 on the lower side of the middle of the first air tube 203 and the lower port of the connector 402 are locked together. The fixed sleeve 403 fastens the lower port of the connector 402 to wrap the first seat post 201.

[0080] The outer port of the first air tube 203 is fixedly connected to the third air tube 206. The third air tube 206 passes through the fixed ring 302 and runs along the handle 101 to the tail seat 102.

[0081] The balloon mechanism 4 also includes an annular top support 404, and a membrane 405 is fixedly embedded inside the annulus of the top support 404;

[0082] Two cylindrical columns 406 are fixedly inserted between the bottom support 401 and the top support 404, and the two cylindrical columns 406 are symmetrical front and back.

[0083] The lower ends of the second column 301 are respectively fixedly connected to the two sides of the second lens tube 306. One of the second lens tubes 306 is used for observation, and the other second lens tube 306 is used for illumination. The second lens tube 306 passes through the fixed ring 302 and is correspondingly inserted into the cylindrical column 406. The end of the second lens tube 306 extends out of the top support 404.

[0084] An inner bladder 407 and an outer bladder 408 are fixedly connected between the bottom support 401 and the top support 404, with the outer bladder 408 located outside the inner bladder 407.

[0085] The cylindrical column 406 is located between the internal capsule 407 and the external capsule 408;

[0086] The inner capsule 407 and the outer capsule 408 enclose the electrosurgical unit 2;

[0087] Water pipes 409 are symmetrically inserted on both sides of the base support 401. The water pipes 409 are inserted through the fixed ring 302 and run along the handle 101 to the tail seat 102. One end of the water pipe 409 is connected between the inner bladder 407 and the outer bladder 408, and the other end of the water pipe 409 is connected to the water pump.

[0088] The working principle of this invention is as follows:

[0089] During endoscopic oral-nasal resection, the monopolar electrosurgical unit inserted through the mouth needs to be bent to reach the lateral pharyngeal recess of the patient. The two finger adjustment components slide along the groove 103, thereby moving the pull rope 112. Through the connection between the pull rope 112 and the inner ball 107, the inner ball 107 overcomes the elastic force of the torsion spring 109 and rotates around the ball axis 108. The connector 110 rotates along the sliding groove 105, thereby causing the blade assembly connected to it to deflect at an angle. By adjusting the appropriate bending angle for different people, the monopolar electrosurgical unit can be smoothly moved to the affected area. The angle can be adjusted to suit different people.

[0090] With the cooperation of the pull cord 112 and the finger adjustment component, when in use, medical staff can insert their fingers into the finger rings 114 of the upper and lower finger adjustment components respectively, and freely operate the sliding finger adjustment components to adjust the angle. When the angle is appropriate and stable, the fingers can apply pressure to the groove 103 through the pressure pad 117 by squeezing the pad 118, and then lock the deflection angle of the blade assembly by locking the movement of the pull cord 112. Both the adjustment and locking of the angle can be done with one hand, improving the convenience of operation.

[0091] When used in conjunction with the balloon mechanism 4, the electrosurgical unit 2 of the blade assembly is first inserted into the balloon mechanism 4 through the connector 402. The electrosurgical unit 2 and the balloon mechanism 4 are then fixed in place by the retaining sleeve 403. Next, the third trachea 206 is connected to the first trachea 203, and the second lens tube 306 is inserted into the column 406. Through the illumination and observation of the second lens tube 306, the balloon mechanism 4 and the blade assembly are sent to the affected area together. The inner balloon 407 and the outer balloon 408 wrap around the electrosurgical unit 2, protecting the blade 205 during the transfer to the affected area, while also protecting the patient's pharynx, thus improving the safety of use.

[0092] During the assembly of the balloon mechanism 4 and the blade assembly, the arc strip 303 is in contact with the upper end of the first support column 201, which makes it easier to connect the electrosurgical mechanism 2 and the connector 402 and facilitates assembly. When the operation is performed, the cylinder inside the second support column 301 is activated to raise the upright 305, so that the arc strip 303 is moved to the side of the blade 205 and the first lens tube 304 on it can illuminate and observe the end of the blade 205. This improves the protection of the endoscope assembly while ensuring the observation of the operation and enhances the visual safety of the operation.

[0093] After the blade assembly and balloon mechanism 4 reach the affected area, the membrane 405 is oriented towards the affected area. The air pump pumps air into the fourth trachea 207 through the fourth trachea 207, the third trachea 206, the first trachea 203, and the second trachea 204, causing the inner balloon 407 to expand and support the affected area. During the operation, the blade 205 is energized to first destroy the membrane 405, exposing the affected area and allowing the tissue to be fully displayed, facilitating the removal of the affected tissue and improving the quality of the surgery.

[0094] During the surgery, circulating water is pumped into the water pipes 409 on both sides. The circulating water enters the space between the inner capsule 407 and the outer capsule 408 through the water pipes 409 to cool the area around the affected area. The cooling effect of the balloon mechanism 4 can solve the problem of damage caused by the blade 205 being too close to the wound. The flow of circulating water allows the blade 205 to get closer to the wound, improving the accuracy of the surgery.

[0095] 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.
