Description

Technical Field

[0001] The present invention relates to the technical field of skull base support, and more particularly to a support device based on transnasal skull base surgery. Background Art

[0002] Transnasal skull base surgery is a minimally invasive surgery commonly used to treat pituitary tumors, cerebrospinal fluid rhinorrhea and other diseases. Compared with traditional craniotomy, transnasal skull base surgery has the advantages of rapid access to the surgical area, good field of view, less traction on brain tissue, and shorter operation time. After transnasal skull base surgery, the intraoperative opening needs to be closed until the opening position heals through the patient's own growth.

[0003] Since the healing period of skull base defect repair materials is usually 2-4 weeks, filling materials are needed to support and protect them during this period. Insufficient or excessive supporting force of the filling materials will lead to poor healing of the skull base defect repair materials, resulting in surgical failure and endangering the patient's life.

[0004] Existing support solutions usually fill the bottom of the skull base defect repair material with filling materials such as gauze or expanded sponge, and fix the position of the filling material by the friction between the filling material and the sides of the nasal cavity. However, during this period, the filling material can easily loosen naturally, resulting in support failure. If a water-filled balloon is directly used instead of the filling material, the support direction cannot be controlled. In addition, since the size and shape of the space after nasal surgery in different patients are different, it is difficult to accurately control the support force by controlling the balloon size, which reduces the success rate of transnasal skull base surgery. Summary of the Invention

[0005] The present invention provides a support device based on transnasal skull base surgery to solve the problem that the support solutions in the existing technology usually fill the bottom end of the skull base defect repair material with gauze or expanded sponge, and the filling material is easily loosened naturally. Directly using a water-filled balloon instead of the filling material cannot control the support direction and support force, thereby reducing the success rate of transnasal skull base surgery.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A support device based on transnasal skull base surgery includes a support plate, which has a certain elasticity. A closed and connected soft membrane is provided on the inner side of the support plate. The outer side of the support plate is connected to an internal support component through a moving component and an adjusting component.

The bottom end of the rotating cylinder is connected to a sliding seat, and both ends of the sliding seat are connected to a control valve. The top of the sliding seat is connected to a support pad through a rotating cylinder, and a pressure sensor is provided on the inner top wall of the support pad.

[0008] Preferably, both ends of the support plate are connected to positioning bags, and the outer sides of the positioning bags are arc-shaped and convex.

[0009] Preferably, the moving assembly includes baffles connected on both sides of the slider, the two baffles, the top of the baffles contacts the inner top wall of the support plate, the two ends of the slider are connected by a pull rope, the pull rope is passed through the support plate, the span of the two ends of the pull rope exceeds the position of the two end surfaces of the support plate, a group of positioning holes are opened on the outside of the support plate, a positioning button is fixedly connected to the pull rope, and the positioning button is passed through any of the positioning holes.

[0010] Preferably, the free ends of the two baffles are provided with connecting cylinders, and the inner sides of both ends of the support plate are connected to limit buttons through springs, and the limit buttons are aligned with the inner walls of the connecting cylinders along an arc.

[0011] Preferably, the adjustment component includes a through hole opened on the slider, a J-shaped telescopic tube is passed through the through hole, the free end of the circular arc section of the J-shaped telescopic tube is in contact with the outer wall of the rotating drum, the free end of the straight section of the J-shaped telescopic tube is connected to an inner tube, the outside of the soft membrane is connected to an outer tube, and the inner tube is passed through the outer tube.

[0012] Preferably, the outer tube and the inner tube are jointly provided with a conversion assembly, the conversion assembly includes a balloon connected to the outer tube, a rotating card in the balloon is provided with a ball valve, a rotating block is connected to the outside of the ball valve, the rotating card of the rotating block is arranged on a fixing hole opened on the outside of the balloon, a first liquid guide tube and a second liquid guide tube are provided in the ball valve, and the plane where the first liquid guide tube and the second liquid guide tube are located is perpendicular to the axis of the rotating block.

[0013] The principle and beneficial effects of this technical solution:

[0014] (1) The inner support assembly provided in the present invention can be adjusted in position by the moving assembly and the adjusting assembly, so that the inner support assembly can directly support the skull base defect repair material of the patient. The support pressure at the bottom end of the skull base defect repair material can be directly known by detecting the reading of the pressure sensor in the inner support assembly. The closed cavity formed between the soft membrane and the support plate can be filled with water through the outer tube, so that the device can be easily placed in the patient's nasal cavity and positioned after being placed in the designated position. When using this device for internal support of skull base defect, first place the arc section of the support plate into the patient's nasal cavity. After moving the device to the vicinity of the skull base repair material, rotate the support plate so that the support plate exposes the connection port between the nasal cavity and the trachea to avoid The device has an excessive impact on the patient's breathing, and then the position and orientation of the rotating cylinder in the inner support assembly are adjusted through the moving assembly and the adjusting assembly. After the adjustment is completed, the position of the device is maintained by the instrument, and then the closed cavity between the soft membrane and the support plate is filled with water through the free end of the outer tube. After the closed cavity is fully expanded, the device can be fully positioned by cooperating with the positioning bags set at both ends of the support plate. At this time, the control valve will open, and water will enter the sliding seat through the control valve, and the support pad can be filled with water through the rotating cylinder. After the support pad is filled, the device is adaptively adjusted by real-time monitoring of the pressure sensor reading on the top wall of the support pad, and pressure monitoring is performed during the postoperative healing period, thereby improving the patient's postoperative healing effect.

[0015] (2) The moving assembly and the adjusting assembly provided in the present invention can respectively adjust the position of the slider and the orientation of the rotating drum on the slider, so that the inner support assembly can directly support the skull base defect repair material at different parts of the patient at the correct angle. When the slider needs to be moved along the slide groove, the positioning button provided in the positioning hole is pulled out, and then the pull rope provided with the positioning button is pulled so that the pull rope pulls the slider to move. After the slider is adjusted to the appropriate position, the positioning button is inserted into the positioning hole at the corresponding position. The limit buttons connected to the inner sides of the two ends of the support plate by springs can help the slider reset to the middle position.

[0016] When the direction of the rotating cylinder needs to be adjusted, water is filled into the inner tube, and the inner tube will cause the J-shaped telescopic tube to expand. The rotating cylinder is lifted up by the free end of the arc section of the J-shaped telescopic tube, and the rotating cylinder is rotated between the two side plates until the rotating cylinder rotates toward the skull base defect. The free end of the inner tube can be closed, and the position of the rotating cylinder can be limited by cooperating with the internal support assembly.

[0017] (3) The conversion assembly provided in the present invention can adjust the water filling route. By rotating the turn block, the turn block will drive the ball valve to rotate. Since the plane where the first liquid guide tube and the second liquid guide tube are located is perpendicular to the axis of the turn block, the rotation of the ball valve will cause the first liquid guide tube and the second liquid guide tube to rotate, thereby changing the conduction state of the inner tube and the outer tube, making it easier for the user to fill in the liquid.
