Description

Technical Field

[0001] The invention relates to the technical field of ear, nose and throat surgery, in particular to an aspirator with a lateral electrocoagulation knife for nasal surgery. Background Art

[0002] With the advancement of medical technology, the concept of minimally invasive surgery has gained popularity. Nasal surgery can usually be performed through natural cavities, with relatively small trauma, fast recovery after surgery, and less obvious scars, which meets the patient's needs for beauty and rapid recovery. The nasal cavity is adjacent to important structures such as the brain and orbits. Lesions in these areas can be approached more directly through the nasal cavity, reducing damage to surrounding normal tissues. Nasal surgery avoids the serious complications that may be caused by large incision surgeries such as craniotomy and thoracotomy, such as infection and large blood vessel damage. Advanced surgical instruments and equipment, such as more sophisticated electrocoagulation knives and laser equipment, make nasal surgery more convenient and efficient.

[0003] During surgery, the heat effect generated by the high-frequency current of the electrocoagulation knife causes the blood vessel wall to coagulate and shrink, thereby quickly stopping bleeding, reducing bleeding during surgery, keeping the surgical field clear, and facilitating surgical operations. The negative pressure generated by the aspirator removes the liquid. Due to the small space in the nasal cavity, the existing electrocoagulation knife and aspirator are not flexible enough to operate, and it is difficult to handle some protruding tissues and polyps with special shapes.

The side electrocoagulation knife assembly 103 is arranged to make it more conducive to performing resection surgery in locations with large space restrictions such as the nasal cavity. By changing the shape of the holding assembly 101, it can be easily operated, reduce the limitation of narrow space, and increase the flexibility of operating the electrocoagulation knife. The holding assembly 101 has a fixed handle and a movable handle that can rotate relative to each other to change the extended shape, so that it is more suitable for surgical environments with limited space such as the nasal cavity, and improves the spatial mobility of the electrocoagulation knife in the nasal cavity. When the outer tube of the aspirator is extended into the lesion position, the side electrocoagulation knife shrinks into the inner part of the outer tube to prevent contact with surrounding healthy tissues. During operation, the tissue is removed by pulling out the outer tube of the aspirator, and the suction tube mouth can stay at the position of the tissue just removed, so that the liquid generated during the removal is sucked out through negative pressure.

[0044] Specifically, the surgical unit 100 includes a gripping assembly 101, an aspirator outer tube assembly 102 disposed at one end of the gripping assembly 101, a side electrocoagulation knife assembly 103 disposed on a side wall of the aspirator outer tube assembly 102, and a rotating assembly 104 disposed in an inner assembly of the gripping assembly 101;

[0076] The suction device having the side electrocoagulation knife assembly 103 is more conducive to performing resection surgery at locations with large space restrictions such as the nasal cavity. When the suction device is extended into the lesion location, the side electrocoagulation knife assembly 103 is retracted into the interior of the suction device outer tube assembly 102 to prevent the electrocoagulation knife from contacting the surrounding healthy tissues. In addition, through the setting of the side electrocoagulation knife assembly 103, during operation, the tissue can be removed by pulling out the suction device outer tube assembly 102. At this time, the suction tube mouth 102a of the suction device outer tube assembly 102 can be pulled outward to stay at the location of the tissue just removed, so that the liquid generated by the side electrocoagulation knife assembly 103 during the removal is sucked out through negative pressure.

[0077] The holding assembly 101 has a fixed handle 101a and a movable handle 101b which can rotate relative to each other to change the extended shape of the holding assembly 101. Due to the limitations of surgeries in space-constrained areas such as the nasal cavity, the spatial movement of the electrocoagulation knife in the nasal cavity is greatly limited. Therefore, by changing the shape of the holding assembly 101, it is possible to facilitate operation and increase the flexibility of operating the electrocoagulation knife.

[0078] The locking rod 104c-2 of the button component 104c is restricted by the waist-shaped hole on the end cover 104a-1 to make a linear slide. When the fixed handle 101a and the movable handle 101b are in the initial position, the locking rod 104c-2 is clamped on the second clamping portion 104a-3f. By pressing the pressing piece 104c-1 of the button component 104c, the locking rod 104c-2 slides from the second clamping portion 104a-3f to the release portion 104a-3e, wherein the shape of the release portion 104a-3e is approximately circular, and the cross-section of the locking rod 104c-2 is The surface is a non-circular structure such as a rectangle or an ellipse, and the shapes of the first clamping portion 104a-3d and the second clamping portion 104a-3f are adapted to the shape of the cross section of the locking rod 104c-2, so that the first clamping portion 104a-3d and the second clamping portion 104a-3f can limit the rotation of the locking rod 104c-2 therein, and the release portion 104a-3e can allow the locking rod 104c-2 to rotate therein; when the locking rod 104c-2 is pressed into the release portion 104a-3e, the movable handle 101b is rotated to a 180-degree position, see the attached Fig. 9 At this time, the pressing member 104c-1 of the button component 104c is released, and the locking rod 104c-2 is reset and enters the first clamping portion 104a-3d. Fig.10 At this time, the extended shape of the gripping component 101 changes, see the attached Fig.11 , combined with the side electrocoagulation knife assembly 103, it can be operated more flexibly and conveniently to complete the cutting of the tissue in the nasal cavity.

[0079] In summary, the present invention is more conducive to performing resection surgery in locations with large space restrictions such as the nasal cavity through the side electrocoagulation knife assembly. When the aspirator is extended into the lesion location, the side electrocoagulation knife shrinks into the interior of the aspirator outer tube assembly to prevent the electrocoagulation knife from contacting the surrounding healthy tissue. In addition, through the setting of the side electrocoagulation knife assembly, the tissue can be removed by pulling out the aspirator outer tube assembly during operation. At this time, the outward withdrawal of the aspirator outer tube assembly allows the suction tube mouth to stay at the location of the tissue just removed, which is convenient for sucking out the liquid generated by the side electrocoagulation knife assembly during resection through negative pressure. The holding assembly has a fixed handle and a movable handle that can rotate relative to each other to change the extended shape of the holding assembly. Due to the limitations of surgeries in spaces such as the nasal cavity, the spatial movement of the electrocoagulation knife in the nasal cavity is relatively limited. Therefore, by changing the shape of the holding assembly, it is easy to operate and increase the flexibility of the electrocoagulation knife operation.
