[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] A closed drainage sinus repair device is used to perform closed drainage inside the sinus, which helps the sinus to recover or heal. Figure 1 As shown, the sinus repair device includes a spiral drainage hose 1, one end of which is provided with a silicone cover plate 2, on which a through tube 21 is fixedly provided, one end of the through tube 21 is fixedly connected to the spiral drainage hose 1, and the other end is fixedly installed with a Luer connector 3.

[0026] The Luer connector 3 is fixedly mounted on the drainage port of the silicone cover plate 2, a drainage pipeline 9 is fixedly connected to the Luer connector 3, a stop clamp 4 is installed on the drainage pipeline 9, and the drainage pipeline 9 can be connected to an external negative pressure device to perform negative pressure drainage on the spiral drainage hose 1.

[0027] A connecting joint 5 is fixedly installed at one end of the drainage pipeline 9 away from the Luer connector 3 , and the connecting joint 5 is connected to the negative pressure device.

[0028] like Figure 3 As shown, in this embodiment, it also includes a guide sheath 6, which is made of elastic material. The guide sheath 6 passes through the inside of the spiral drainage hose 1 to facilitate the spiral drainage hose 1 to extend into the sinus tract, and the guide sheath 6 is provided with scale lines 7. The scale lines 7 can measure the actual depth of the sinus tract during the process of guiding the spiral drainage hose 1 to extend into the sinus tract, which helps the doctor to understand the condition of the sinus tract and the actual insertion length of the spiral drainage hose 1.

[0029] A push rod 8 is slidably installed inside the guide sheath 6 for guiding the guide sheath to facilitate the guide sheath 6 to extend into the sinus tract. An internal support clamp is fixedly provided at one end of the push rod 8 and the internal support clamp is inserted into the guide sheath 6.

[0030] like Figure 2-4 As shown, the spiral drainage hose 1 includes a tube body 10, which is a flexible hose and has a drainage outer groove 11. An inner tube 12 is provided in the middle of the tube body 10. The spiral drainage hose 1 is fixedly connected to the through tube 21, and the inner tube 12 is connected to the through tube 21.

[0031] The cross-sectional structure of the drainage outer groove 11 includes V-shaped, circular, rectangular, and arc-shaped. In this embodiment, the drainage outer groove 11 has a V-shaped cross-section and is used to drain and aspirate the accumulated fluid in the sinus or the physiological saline for flushing.

[0032] In this embodiment, the tube body 10 is a spiral structure, and the drainage outer groove 11 is spirally shaped on the outside of the spiral drainage hose 1. The tube body 10 adopts a spiral structure. When the tube body 10 is spirally twisted, the opening size of the drainage outer groove 11 can be controlled. After adjusting the size of the drainage outer groove 11, the granulation tissue in the sinus can be prevented from being sucked into the drainage outer groove 11 during the drainage process, and the tissue will not be damaged.

[0033] When the spiral drainage hose 1 is inserted into or withdrawn from the sinus, the spiral tube body 10 follows the tissue lines in the sinus and will not cause damage to the tissue in the sinus.

[0034] The tube body 10 is provided with a plurality of drainage outer grooves 11 , and the drainage outer grooves 11 are provided with drainage holes 13 distributed in an array, and the drainage holes 13 are communicated with the inner tube 12 .

[0035] A developing marking line 14 is fixedly provided on the spiral drainage hose 1 for X-ray development, and a flushing tube 15 is fixedly connected to the drainage pipeline 9 for injection and cleaning of physiological saline.

[0036] Here’s how it works:

[0037] Before use, the guide sheath 6 can be extended into the patient's sinus tract to measure the depth of the sinus tract; according to the depth of the sinus tract, the sinus tract repair device for negative pressure drainage can be cut; when installing the sinus tract repair device, the guide sheath 6 is inserted into the inner tube 12 of the sinus tract repair device, the internal support and expansion clamp of the guide sheath 6 is opened, the sinus tract repair device is extended into the bottom of the patient's sinus tract cavity, the internal support and expansion clamp of the guide sheath 6 is retracted, and the guide sheath 6 is removed and installed. The material of the guide sheath 6 is a polymer elastic material, and the internal support and expansion clamp is made of medical stainless steel or a medical polymer elastic material.

[0038] Then install the spiral drainage hose 1 equipped with the silicone cover plate 2 into the sinus tract. During the extraction and installation process, the spiral structure will follow the sinus tissue and will not damage the patient's sinus tissue. The drainage pipeline 9 with the Luer connector 3 is connected and installed between the silicone cover plate 2 and the negative pressure device to perform negative pressure drainage. If physiological saline is injected into the inner tube 12 for cleaning through the flushing tube 15, the physiological saline will enter the drainage hole 13 after cleaning from the drainage outer groove 11. The cleaning effect is good and the physiological saline after cleaning is easy to recover.

[0039] Example 2

[0040] A non-spiral drainage hose is used to replace the spiral drainage hose 1. The non-spiral drainage hose is provided with a spiral drainage outer groove 11. The rest of the structure is the same as that of the first embodiment.

[0041] Working principle:

[0042] When a non-spiral drainage hose is used, the spiral drainage outer groove 11 can prevent the growth of new granulation tissue, protect the wound tissue from being damaged, and help the recovery of the wound tissue.
