Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a flushing and suction device for maxillary sinus fungal surgery. Background Technology

[0002] Currently, the treatment of non-invasive fungal sinusitis in clinical practice often involves endoscopic sinus surgery. This involves opening the sinus ostia, removing fungal tissue from the sinuses, restoring unobstructed drainage of the nasal cavity and sinuses, eliminating the closed, anaerobic environment, and preserving the sinus mucosa and bone walls. This aims to eradicate the lesion and restore the physiological function of the sinuses. During the surgery, the surgical site needs to be continuously irrigated, and any bleeding, exudate, pus, or other fluids must be promptly aspirated to ensure that the surgeon can clearly observe the surgical site. Using an irrigation and suction device allows for direct irrigation and aspiration of the surgical site, reducing the chance of contamination.

[0003] However, the existing irrigation and suction devices for maxillary sinus fungal surgery are relatively simple, and the external installation and adjustment structure of the irrigation and suction device is lacking, which affects the ease of installation and use of the irrigation and suction device. Utility Model Content

[0004] The purpose of this invention is to solve the problem of the lack of a certain installation and adjustment structure on the outside of the irrigation and suction device mentioned in the background art, and to propose an irrigation and suction device for maxillary sinus fungal surgery.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A surgical irrigation and suction device for maxillary sinus fungal infection includes a mounting plate and a suction and irrigation mechanism. The bottom of the mounting plate has a mounting groove, and a screw is rotatably connected to the mounting groove. One end of the screw passes through the inner wall of the mounting groove and is fixedly connected to a knob. One end of the knob is slidably inserted with a locking mechanism. The mounting plate is surrounded by multiple slots corresponding to the locking mechanism. A transmission block is threaded onto the screw. The bottom of the transmission block is connected to a support block via a turnbuckle. The support block and the transmission block are connected via a telescopic rod. The bottom of the support block is rotatably connected to a mounting sleeve via a rotating rod. The mounting sleeve is fixedly fitted onto the outside of the suction and irrigation mechanism.

[0007] Preferably, the top of the mounting plate is fixedly connected with a plurality of fastening blocks, and the fastening blocks are provided with fastening ports.

[0008] Preferably, a sliding rod is fixedly connected in the mounting groove, and the transmission block is provided with a sliding opening corresponding to the sliding rod. Multiple steel balls are slidably connected in the sliding opening, and the edges of the steel balls are in contact with the sliding rod.

[0009] Preferably, the clamping mechanism includes a clamping rod, with a clamping sleeve fixedly sleeved at one end of the clamping rod near the mounting plate, and a pull rod fixedly connected at the other end of the clamping rod away from the clamping sleeve.

[0010] Preferably, a spring is fitted onto the lever, and the two ends of the spring are fixedly connected to the lever and the knob, respectively.

[0011] Preferably, a torsion spring is sleeved on the rotating rod, and the two ends of the torsion spring abut against the support block and the mounting sleeve, respectively.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By setting multiple adjustment mechanisms, the flushing suction device can be freely installed and fixed according to actual usage needs, thereby effectively improving the ease of installation of the flushing suction device;

[0014] 2. The fastening block in this utility model can easily fix the mounting plate, the clamping mechanism can easily fix the knob, the slide rod can provide a certain support and guidance for the transmission block, and the telescopic rod can prevent the support block from shaking.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-2 A surgical irrigation and suction device for maxillary sinus fungal infection includes a mounting plate 1 and a suction and irrigation mechanism 2. The top of the mounting plate 1 is fixedly connected to a plurality of fastening blocks 11, and the fastening blocks 11 are provided with fastening ports to facilitate fixing the mounting plate 1. The bottom of the mounting plate 1 is provided with a mounting groove, and a screw 3 is rotatably connected in the mounting groove to drive the transmission block 5 to slide. One end of the screw 3 passes through the inner wall of the mounting groove and is fixedly connected to a knob 4 to drive the screw 3 to rotate.

[0020] In this embodiment, a slide rod 12 is fixedly connected in the mounting groove, and a sliding opening corresponding to the slide rod 12 is provided on the transmission block 5. Multiple steel balls 13 are slidably connected in the sliding opening. The edges of the steel balls 13 contact the slide rod 12 to reduce the friction between the transmission block 5 and the inner wall of the sliding opening. A locking mechanism is slidably inserted into one end of the knob 4, and multiple slots corresponding to the locking mechanism are provided around the mounting plate 1 for fixing the knob 4.

[0021] In this embodiment, the clamping mechanism includes a clamping rod 14. A clamping sleeve 15 is fixedly sleeved on one end of the clamping rod 14 near the mounting plate 1 to prevent the clamping rod 14 from falling off the knob 4. A pull rod 16 is fixedly connected to the other end of the clamping rod 14 away from the clamping sleeve 15. A spring 17 is sleeved on the clamping rod 14. The two ends of the spring 17 are fixedly connected to the clamping sleeve 15 and the knob 4 respectively, providing a certain elastic support for the clamping rod 14.

[0022] In this embodiment, a transmission block 5 is threaded onto the screw 3. The bottom of the transmission block 5 is connected to a support block 7 via a turnbuckle 6. The support block 7 and the transmission block 5 are connected by a telescopic rod 8 to prevent the support block 7 from shaking. The bottom of the support block 7 is rotatably connected to an mounting sleeve 10 via a rotating rod 9. The mounting sleeve 10 is fixedly fitted onto the outside of the suction and rinsing mechanism 2. A torsion spring is fitted onto the rotating rod 9. The two ends of the torsion spring abut against the support block 7 and the mounting sleeve 10 respectively, providing a certain torsional support for the support block 7.

[0023] In this embodiment, rotating the knob can drive the screw to rotate and cause the transmission block to slide, thereby adjusting the position of the suction and rinsing mechanism 2. Then, the knob is fixed by the clamping mechanism. The height of the suction and rinsing mechanism 2 can be adjusted by the turnbuckle. At the same time, the rotating rod can be set to freely adjust the operating angle of the suction and rinsing mechanism 2.

[0024] In this embodiment, the flushing suction device can be freely installed and fixed according to actual usage needs by setting multiple adjustment mechanisms, thereby effectively improving the ease of installation of the flushing suction device.
