Other instruments besides the suction tube can be installed through the reserved hole and the reserved interface.

Furthermore, a plurality of preformed holes are formed in the end portion of the bronchoscope in the circumferential direction, a plurality of reserved interfaces are arranged at the other end of the bronchoscope, the preformed holes are the same in number with the reserved interfaces, and the preformed holes are communicated in a one-to-one correspondence mode.

The reserved interfaces can be used for installing instruments such as a laser probe, an optical lens and a light source, when surgical instruments enter the treatment from the main hole, observation and diagnosis are completed, and the operation time is further shortened.

Further, the aperture of the negative pressure hole and the aperture of the reserved hole are smaller than that of the main hole.

The main hole has larger aperture and is used for the entry of instruments such as conventional surgical forceps and the like.

Further, the diameter of the bronchoscope is 4.2mm, and the diameter of the main hole is 3.5 mm.

Further, one end of the bronchoscope, which is far away from the main interface and the negative pressure interface, is provided with a slope.

The beveled bronchoscope end can be more easily inserted into a patient.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

Referring to fig. 1 to 3, the utility model provides a rigid bronchoscope, which includes a bronchoscope 10, wherein the bronchoscope 10 is further provided with a negative pressure hole 30 in addition to a main hole 20 for passing a conventional instrument, and the negative pressure hole 30 is connected with a suction tube for sucking sputum during operation treatment, so that the operation efficiency can be improved.

Specifically, the main hole 20 and the negative pressure hole 30 are both axially formed in the bronchoscope 10, the main hole 20 is formed along the central axis of the bronchoscope 10, and the negative pressure hole 30 is formed in the side wall of the main hole 20. One end of the bronchoscope 10 is provided with a main interface 21 and a negative interface 31 which are respectively communicated with the main hole 20 and the negative hole 30. After the bronchoscope 10 is inserted into the body of a patient, conventional surgical instruments such as forceps can enter through the main hole 20, and a suction tube can be connected to the negative pressure port 31 to suck sputum through the negative pressure hole 30.

Further, a preformed hole 40 is further formed in the tube wall of the bronchoscope 10, the preformed hole 40 is also formed in the axial direction of the bronchoscope 10, and a preformed connector 42 communicated with the preformed hole 40 is arranged at one end provided with the main connector 21 and the negative pressure connector 31. In this embodiment, the plurality of preformed holes 40 are formed on the tube wall of the bronchoscope 10 around the circumferential direction, and the plurality of preformed connectors 42 are formed at the other end, are the same as the plurality of preformed holes 40, and are communicated in a one-to-one correspondence manner. The preformed hole 40 and the preformed interface 42 can be used for installing devices such as a laser probe, an optical lens and a light source, and can complete operations such as observation, diagnosis and illumination while performing treatment through the main hole 20 by using conventional instruments.
