Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an ENT nasal suction tube for an optical navigation system. Background Art

[0002] Nasal suction tubes are common surgical instruments in ENT surgeries, mainly used to clear secretions or foreign objects from the patient's nasal cavity. Existing nasal suction tubes are generally held by doctors and entered into the cavity, and the operation is performed based on the doctor's experience. If the experience is insufficient or the strength and direction are not chosen correctly, it is easy to damage human tissue and cause secondary harm to the patient. If the lesion is not clearly identified during a single exploration, it will be used multiple times, and the residual organic matter, inorganic matter and microorganisms will increase, making disinfection and sterilization difficult, increasing the risk of infection. Existing ENT nasal suction tubes are mostly made of stainless steel, which is relatively bulky. Doctors will feel tired due to long-term holding during the operation, which reduces the accuracy of the operation and leads to increased operation time or failure. Summary of the invention

[0003] In order to solve the problems existing in the prior art, the present invention proposes an ENT nasal suction tube for an optical navigation system, which can be used in conjunction with the optical navigation system so that the optical navigation system can track the nasal suction tube within the tracking range of a spatial locator.

[0004] To achieve the above-mentioned purpose, the present invention proposes an otolaryngology nasal suction tube for an optical navigation system, comprising a nasal suction tube body (10), a positioning member (20) and a buckle (30), wherein the nasal suction tube body (10) comprises a handle (12) and a nasal suction tube (11) connected to the handle (12), and a fixing column (13) is provided on the handle (12); the positioning member (20) comprises a coordinate body (21), a reflective ball base (22) and a reflective ball (23); The reflective ball base (22) is mounted on the coordinate body (21), and the reflective ball (23) is fixed on the reflective ball base (22); the buckle (30) comprises a positioning seat (31), a locking slider (32) and a positioning bead (33); the buckle (30) is used to connect the positioning member (20) and the nasal suction tube body (10); the locking slider (32) cooperates with the positioning bead (33) to fix the positioning seat (31) and the nasal suction tube body (10) together.

[0005] Preferably, the nasal suction tube (11) comprises a straight portion (111) and a bent portion (112); the straight portion (111) is connected to the handle (12); and an angle of 120° is formed between the straight portion (111) and the bent portion (112).

[0006] Preferably, two fixing columns (13) are provided on the handle (12), which are respectively referred to as a first fixing column (131) and a second fixing column (132), and the first fixing column (131) and the second fixing column (132) have different sizes.

[0007] Preferably, the inner diameters of the straight portion (111) and the bent portion (112) are 1.70 mm.

[0008] Optionally, the coordinate body (21) can establish a coordinate system in different forms. As long as it can be tracked by the spatial positioning device, any form of the coordinate body (21) is acceptable. In some embodiments, the coordinate body (21) establishes a coordinate system by fixing reflective balls at four points, and the centers of the four reflective balls are coplanar.

[0009] Through the coordinate system established by the positioning member (20), the reflective ball (23) can be tracked by the spatial positioning device of the optical navigation system, the relative position relationship between the nasal suction tube body (10) and the positioning member (20) is fixed, and the nasal suction tube body (10) can be tracked in real time by the spatial positioning device of the optical navigation system.
