Description

Technical Field

[0001] This utility model relates to a hysteroscope, specifically a visual hysteroscope. Background Technology

[0002] Hysteroscopy allows for imaging of the uterus for surgical purposes. Currently, when using a hysteroscope to image other locations, because the lens and the hysteroscope body are fixed, the entire hysteroscope must be rotated to reach the target position. However, rotating the entire hysteroscope is inconvenient and hinders the operation of medical staff. A solution exists on the market: installing a motor inside the hysteroscope to drive its rotation independently. However, the cost of an internal motor is high, and adding a motor would also increase the weight of this relatively small surgical instrument, making it impractical. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a visual hysteroscope. This utility model adopts a manual operation method, which allows for independent rotation of the endoscope body. It is low in cost, convenient to operate, and lightweight.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: a visual hysteroscope, comprising a body and an outer shell, wherein a guide sleeve is fixed inside the outer shell, and through holes are provided at both the front and rear of the outer shell, and the endoscope is inserted through the through holes and the guide sleeve; the endoscope body is also provided with a rotating rod, and a rotating ring hole is provided on the outer wall of the outer shell, and the rotating rod extends out of the rotating ring hole to the outside, and when the rotating rod is rotated, the rotating rod can rotate the endoscope body.

[0005] The through hole is a front hole and a rear hole. The guide sleeve is fixed in the front hole, and a bearing is provided in the rear hole. The mirror body is installed in the guide sleeve and the bearing.

[0006] The mirror body is provided with an annular protrusion, and the inner wall of the guide sleeve is provided with an annular groove, in which the annular protrusion is placed.

[0007] The rotating rod includes a connecting rod, a transverse rod, and a handle. One end of the connecting rod is fixed to the mirror body. One end of the transverse rod is fixed to the connecting rod, and the other end extends through the rotating ring hole to the outside of the outer shell. The handle is connected to the transverse rod.

[0008] The angle of the rotating ring hole is 300°–350°.

[0009] The end of the lens body is provided with a bend, and the lens is disposed inside the bend.

[0010] In summary, this utility model achieves the following technical effects:

[0011] This invention features an outer shell on the endoscope body, with a rotating rod mounted on the shell. The rotating rod is connected to the endoscope body; when the rotating rod is turned, it rotates the endoscope body, thereby rotating the lens and enabling the capture of images from multiple angles, maximizing the viewing angle of the hysteroscopy. This invention eliminates the need for motors or other driving components, resulting in low cost, light weight, and easy operation. It can be operated with one hand; one hand holds the hysteroscope body, and the thumb or other fingers of the same hand can turn the rotating rod. Attached Figure Description

[0020] Example:

[0021] Figure 1 This is a cross-sectional view of a visual hysteroscope, including a hysteroscope body 1 with a bend at one end and a lens 5 disposed within the bend. It also includes a housing 2, within which a guide sleeve 3 is fixed. The housing 2 has through holes at both its front and rear, through which the hysteroscope body 1 passes. The hysteroscope body 1 is further equipped with a rotating rod 4. A rotating ring hole 23 is formed on the outer wall of the housing 2, through which the rotating rod 4 extends to the outside. When the rotating rod 4 is rotated, it causes the hysteroscope body 1 to rotate.

[0022] This invention features an outer shell on the endoscope body, with a rotating rod mounted on the shell. The rotating rod is connected to the endoscope body; when the rotating rod is turned, it rotates the endoscope body, thereby rotating the lens and enabling the capture of images from multiple angles, maximizing the viewing angle of the hysteroscopy. This invention eliminates the need for motors or other driving components, resulting in low cost, light weight, and easy operation. It can be operated with one hand; one hand holds the hysteroscope body, and the thumb or other fingers of the same hand can turn the rotating rod.

[0023] The through holes are a front hole 21 and a rear hole 22. The guide sleeve 3 is fixed in the front hole 21, and a bearing is provided in the rear hole 22. The mirror body 1 passes through the guide sleeve 3 and the bearing.

[0024] The mirror body 1 is provided with an annular protrusion 11, and the inner wall of the guide sleeve 3 is provided with an annular groove 31, and the annular protrusion 11 is placed in the annular groove 31.

[0025] When the mirror body rotates, the annular protrusion 11 provides a limiting function to prevent the mirror body from detaching from the outer shell, and the bearing can reduce friction and facilitate the adjustment of the mirror body angle.

[0026] The rotating rod 4 includes a connecting rod 41, a transverse rod 42, and a handle 43. One end of the connecting rod 41 is fixed to the mirror body 1. One end of the transverse rod 42 is fixed to the connecting rod 41, and the other end extends through the rotating ring hole 23 to the outside of the outer shell 2. The handle 43 is connected to the transverse rod 42.

[0027] The outer end of the rotating rod is located outside the housing, making it easier for medical staff to operate. It adopts both mechanical and manual operation, which is convenient. Medical staff can rotate the lens angle according to different patients' conditions. It also has a simple structure and low cost.

[0028] Figure 2 yes Figure 1 The right view shows that the angle of the rotating ring hole 23 is 300°–350°. The rotating ring hole 23 is not a circle, but has a solid position 24, which serves to connect the lens body. Since the field of view of the lens itself is expanded, a rotation angle of 300°–350° is sufficient to capture all angle areas.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
