Description

Technical Field

[0001] The utility model relates to the technical field of endoscopes, in particular to an endoscope steering device and an endoscope. Background Art

[0002] An endoscope can enter small cavities in the human body (such as bile ducts, lymphatic vessels, ureters, and bronchi). Therefore, the endoscope has important clinical significance for medical diagnosis and treatment. However, the space inside the endoscope is very limited, and lines for transmitting light and image data need to be arranged inside the endoscope, which results in a small aperture of the instrument channel. In the prior art, the instrument channel is empty in the non-operative state. During the operation, the doctor passes the surgical instrument through the instrument channel to reach the surgical site in the patient's body. Because the aperture of the instrument channel is small, some surgical instruments with larger sizes cannot pass through the instrument channel, resulting in the doctor being unable to use surgical instruments with larger sizes for the operation. Content of the Utility Model

[0003] Based on this, in view of the above problems, it is necessary to provide an endoscope steering device and an endoscope that allow doctors to use surgical instruments with larger sizes for the operation.

[0004] In order to solve the above problems, the utility model provides the following technical solutions:

[0005] An endoscope steering device, comprising:

[0006] An operating handle;

[0007] An insertion tube fixedly connected to the operating handle, the insertion tube having a first duct; and

[0008] A connecting tube fixedly connected to the operating handle, the connecting tube having a second duct, the second duct communicating with the first duct to jointly form an adjustment channel with the first duct;

[0009] A steering assembly, including a force-applying member, a transmission member, and an external member. The force-applying member is rotatably connected to one end of the connecting tube away from the operating handle. The transmission member passes through the adjustment channel. Two ends of the transmission member are respectively fixedly connected to the force-applying member and the external member. The external member is rotatably connected to one end of the insertion tube away from the operating handle. When the force-applying member rotates relative to the insertion tube, the force-applying member drives the transmission member and the external member to rotate relative to the insertion tube; the external member is used for fixedly connecting a surgical instrument.

[0010] The endoscope steering device has at least the following beneficial effects:

[0011] The manufacturer or doctor can fixedly connect the surgical instrument to the external member. During the operation, the doctor inserts the insertion tube into the surgical site in the patient's body, and manipulates the depth of insertion of the insertion tube into the patient's body by holding and pushing or pulling the operation handle, so as to adjust the position of the surgical instrument. By rotating the force - applying member, the transmission member and the external member are rotated, so as to rotate the surgical instrument, and thus adjust the posture of the surgical instrument. In this way, the doctor can adjust the position and posture of the surgical instrument to perform the operation. Even a relatively large - sized surgical instrument can be fixedly connected to the external member and follow the insertion tube into the surgical site in the patient's body. Therefore, the endoscopic orientation device provided by the present utility model allows the doctor to use a relatively large - sized surgical instrument for the operation.

[0012] In one embodiment, the transmission member is bonded to the force - applying member.

[0013] With such a setting, it is convenient to achieve the fixed connection between the transmission member and the force - applying member.

[0014] In one embodiment, the external member is bonded to the transmission member.

[0015] With such a setting, it is convenient to achieve the fixed connection between the external member and the transmission member.

[0017] With such a setting, normal saline / medicinal liquid / gas / staining agent / contrast agent can be perfused into the surgical site through the irrigation channel, enabling the doctor to perform various surgical operations on the surgical site.

[0018] In one embodiment, a first hollow channel is provided on the operation handle, a second hollow channel is provided on the external member, and the first hollow channel, the first pipeline and the second hollow channel are communicated in sequence to form an irrigation channel, and both ends of the irrigation channel are communicated with the outside.

[0019] With such a setting, normal saline / medicinal liquid / gas / staining agent / contrast agent can be perfused into the surgical site through the irrigation channel, enabling the doctor to perform various surgical operations on the surgical site.

[0020] The present utility model also provides an endoscope, which includes the above - mentioned endoscopic orientation device, and the surgical instrument is fixedly connected to the external member.

[0021] This endoscope has at least the following beneficial effects:

[0022] The manufacturer or doctor can fixedly connect the surgical instrument to the external component. During the operation, the doctor inserts the insertion tube into the surgical site in the patient's body and manipulates the depth of insertion of the insertion tube into the patient's body by holding and pushing or pulling the operation handle, thereby adjusting the position of the surgical instrument. By rotating the force - applying member, the transmission member and the external component are rotated, thereby rotating the surgical instrument and adjusting the posture of the surgical instrument.
