Description

[0002] With the continuous innovation of surgical technology, the application scope of small incisions or deep surgeries with natural cavities is becoming more and more extensive. For example, endoscopic combined oral and nasal approach resection surgery is a common surgery for skull base tumors. However, the surgical field is close to the internal carotid artery. Traditional sharp separation techniques have poor hemostasis effects and high operation risks, and the separation time is long. Monopolar electrocoagulation can effectively separate tissues, but traditional electrocautery has limited mobility during endoscopic guidance of narrow cavity operations. Therefore, when using traditional monopolar electrocoagulation in special parts of complex cavities, separation often needs to be performed at a distance from the target. This results in more tissue residue, which affects the tumor resection rate, increases the operation time, and indirectly increases the potential risks of the surgery.

[0003] Currently, there are no suitable coagulation monopoles for deep incisions, especially transoral ones, where the catheter needs to make turns, a requirement that conventional coagulation monopoles struggle to meet. This invention aims to provide a safer and more effective cutting and separation solution through the development of a new coagulation monopole, thereby improving the success rate of nasopharyngeal carcinoma surgery and the quality of life of patients.

The middle first lens tube 304 is used for observation, and the remaining first lens tubes 304 are used for illumination. A vertical rod 305 is fixedly connected to the lower surface of the arc bar 303. The lower end of the vertical rod 305 is embedded in the second seat post 301 and connected to the second seat post 301 via a cylinder. Initially, the arc bar 303 is in contact with the upper end of the first seat post 201. When activated, the vertical rod 305 is pushed out by the cylinder, so that the arc bar 303 is arranged around the outside of the cutting head 205. A fixing ring 302 is fixedly sleeved on the outer side of the upper portion of the second seat post 301 .

[0024] The outer side of the cutter head assembly is wrapped with a balloon mechanism 4; The balloon mechanism 4 includes an annular bottom support 401, a funnel-shaped receiving seat 402 is fixedly embedded in the ring of the bottom support 401, and a fixing sleeve 403 is fastened to the lower end of the receiving seat 402; The electric knife mechanism 2 of the knife head assembly is inserted into the balloon mechanism 4 through the socket 402. The retaining ring 202 on the lower side of the middle of the first air tube 203 is locked with the lower end of the socket 402. The fixed sleeve 403 is fastened to the lower end of the socket 402 to wrap the first seat column 201. The outer end of the first air pipe 203 is fixedly connected to the third air pipe 206. The third air pipe 206 passes through the fixed ring 302 and extends along the handle body 101 to the tailstock 102. The ends of the third air pipes 206 on both sides are commonly connected to the fourth air pipe 207 of the external air pump.

[0025] The balloon mechanism 4 further includes an annular top support 404, within the ring of which a film 405 is fixedly embedded. A column 406 is fixedly inserted between the bottom support 401 and the top support 404. There are two columns 406, and the two columns 406 are symmetrical front to back. Second lens tubes 306 are fixedly connected to both sides of the lower end of the second seat column 301, one of the second lens tubes 306 is used for observation, and the other second lens tube 306 is used for lighting. The second lens tubes 306 are inserted through the fixing ring 302 and correspondingly penetrate into the cylinder 406, and the end of the second lens tube 306 extends out of the top support 404.

[0026] An inner bag 407 and an outer bag 408 are fixedly connected between the bottom support 401 and the top support 404, and the outer bag 408 is located outside the inner bag 407; The cylinder 406 is located between the inner capsule 407 and the outer capsule 408; The inner capsule 407 and the outer capsule 408 enclose the electrosurgical mechanism 2; Water pipes 409 are symmetrically inserted on both sides of the bottom support 401. The water pipes 409 are inserted through the fixed ring 302 and extend along the handle body 101 to the tail seat 102. One end of the water pipe 409 is connected between the inner bag 407 and the outer bag 408, and the other end of the water pipe 409 is connected to the water pump.

[0027] The working principle of the present invention is as follows: When performing an endoscopic combined oral and nasal approach resection surgery, the monopolar electric knife inserted into the mouth needs to be bent to reach the patient's lateral pharyngeal recess, and the upper and lower finger adjustment components slide along the groove 103, thereby driving the pull rope 112 to move. 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 shaft 108. The connecting column 110 rotates along the displacement groove 105, thereby driving the deflection angle of the blade head assembly connected thereto. The appropriate bending angle is adjusted for different people, so that the monopolar electric knife can be smoothly moved to the affected area, and the angle can be adjusted to adapt to different people's use.

[0028] Through the cooperation of the pull rope 112 and the finger adjustment assembly, when in use, the medical staff inserts their fingers into the finger rings 114 of the upper and lower finger adjustment assemblies respectively, and operates the sliding finger adjustment assembly at will 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 layer 118, and then lock the deflection angle of the blade head assembly by locking the movement of the pull rope 112. The adjustment and locking of the angle can be performed with one hand, which improves the convenience of operation.

[0029] When used in conjunction with the balloon mechanism 4, first, the electrosurgical mechanism 2 of the blade head assembly is inserted into the balloon mechanism 4 through the socket 402, and the electrosurgical mechanism 2 and the balloon mechanism 4 are fixed in place by the fixing sleeve 403. Then, the third trachea 206 and the first trachea 203 are connected, and the second lens tube 306 is inserted into the cylinder 406. Through the illumination and observation of the second lens tube 306, the balloon mechanism 4 and the blade head assembly are sent to the affected area together. The inner capsule 407 and the outer capsule 408 wrap the electrosurgical mechanism 2 to protect the blade head 205 during the transfer to the affected area, and at the same time protect the patient's pharynx, thereby improving the safety of use.

[0030] When assembling the balloon mechanism 4 and the cutting head assembly, the arc strip 303 is in a state of being in contact with the upper end of the first seat column 201, so that it is easier to plug in the electric knife mechanism 2 and the socket 402, and to facilitate assembly. When the operation is in progress, the cylinder inside the second seat column 301 is started to lift the vertical rod 305, so that the arc strip 303 is moved to the side of the cutting head 205 and the first lens tube 304 thereon can illuminate and observe the end of the cutting head 205, thereby improving the protection of the endoscope assembly while ensuring the observability of the operation, thereby improving the visual safety of the operation.

[0031] After the cutting head assembly and the balloon mechanism 4 have arrived at the affected area, the film 405 is directed toward the affected area, and the air pump pumps gas into the fourth trachea 207 through the fourth trachea 207, the third trachea 206, the first trachea 203 and the second trachea 204, so that the inner balloon 407 expands to support and expand the affected area. In this way, when performing an operation, the cutting head 205 is powered on to destroy the film 405 first, exposing the affected area and fully displaying the tissue of the affected area, which facilitates the removal of the affected tissue and improves the quality of the operation.

[0032] During the operation, circulating water is input into the water pipes 409 on both sides through a water pump. The circulating water enters between the inner capsule 407 and the outer capsule 408 through the water pipe 409 to cool down the area around the affected area. The cooling of the balloon mechanism 4 can solve the problem of damage caused by the blade 205 being too close to the wound. The introduction of circulating water allows the blade 205 to approach the wound, thereby improving the accuracy of the operation.
