[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] Referring to the accompanying drawings: This gynecological curettage includes a curettage spoon 1, a connecting rod 2, and an adjusting rod 3. The curettage spoon 1 is connected to the connecting rod 2. The connecting rod 2 has an assembly base 21. A positioning unit 4 is arranged on the assembly base 21. The adjusting rod 3 has an assembly mating surface 31 in contact with the assembly base 21. The assembly mating surface 31 is provided with a plurality of positioning nodes 5 distributed along the length direction of the adjusting rod 3 and defining different adjustment lengths, as well as a first guide channel 6 for guiding the positioning unit 4 to reach the corresponding positioning node 5, and a second guide channel 7 matching the positioning node 5. The first guide channel 6 and the second guide channel 7 are interconnected. The principle of the utility model is that the adjusting rod 3 is sleeved on the connecting rod 2, the assembly base surface 21 and the assembly mating surface 31 are in contact and realize relative sliding, and the positioning unit 4 enters into the first guide channel 6. When the use position of the adjusting rod 3 needs to be adjusted, the positioning unit 4 moves synchronously in the first guide channel 6 through the movement of the adjusting rod 3. When the medical staff adjusts the adjusting rod 3 to the required use position (i.e. the use length displayed between the connecting rod 2 and the adjusting rod 3), the positioning unit 4 is transferred from the first guide channel 6 to the second guide channel 7, and the position is determined when reaching the positioning node 5, thereby preventing the position adjustment of the adjusting rod 3. At the same time, the setting of multiple positioning nodes 5 makes each positioning node 5 represent a different adjustment length, which increases the selectivity.

[0020] The first guide channel 6 and the second guide channel 7 are arranged vertically. Such an arrangement enables the positioning unit 4 to enter the second guide channel 7 from the first guide channel 6 only by rotating the adjusting rod 3, and as the rotation amplitude increases, the positioning unit 4 synchronously enters the positioning node 5. The positioning node 5 also has the function of limiting the rotation amplitude of the adjusting rod 3. At the same time, the adjusting rod 3 cannot continue to move after the vertical positioning unit 4 enters the second guide channel 7, thereby realizing the adjusted positioning, and the operation is simple and convenient.

[0021] The assembly mating surface 31 is provided with an entry turning point 8 and an exit turning point 9 for guiding the positioning unit 4 from the first guide channel 6 to the second guide channel 7. The turning directions of entering the turning point 8 and leaving the turning point 9 are arc-shaped directions, which can be clearly felt by the user and will play a corresponding prompting and guiding role, so that the user can predict that the positioning unit 4 has reached the entry turning point 8 or the exit turning point 9, and can also increase the inlet size of the second guide channel 7, so that the positioning unit 4 can quickly enter or leave the second guide channel 7.

[0022] Both the entry turning point 8 and the exit turning point 9 are formed with a fitting wall 10 which is completely fitted on a part of the surface of the positioning unit 4 when the positioning unit 4 reaches the entry turning point 8 or the exit turning point 9, so that the positioning unit 4 is accurately positioned at the entry turning point 8 or the exit turning point 9 to match the accuracy of the positioning unit 4 entering or leaving the second guide channel 7.

[0023] The first guide channel 6 and the second guide channel 7 constitute a curb 20 arranged on the adjusting rod 3, and the curb 20 has two symmetrically distributed on both sides of the center line of the adjusting rod 3; the positioning unit 4 is a rod-shaped component, which has two positioning ends when it is arranged on the connecting rod 2, and each positioning end moves in the corresponding curb 20. Such a setting makes the overall use stability of the adjusting rod 3 good and will not get stuck during use.

[0024] The positioning node 5 includes a semi-enclosed wall 51 formed on the assembly mating surface 31, and a positioning space 52 defined within the semi-enclosed wall 51 and allowing the positioning end of the positioning unit 4 to be placed therein. The semi-enclosed wall 51 contacts a part of the surface of the positioning end when the positioning end of the positioning unit 4 is placed in the positioning space 52. Such a setting enables a tight fit with a clearance of 0 between the positioning unit 4 and the positioning node 5. Such a matching mode not only does not cause difficulty in the entry and exit of the positioning unit 4, but also ensures the stability of the positioning unit 4 in the positioning node 5. In this embodiment, the positioning node 5 is a through hole, the hole wall of which forms the semi-enclosed wall 51, and the space within which the positioning unit 4 is placed forms the positioning space 52.

[0025] A transparent gripping handle 30 is mounted on the adjusting rod 3. This arrangement is made taking into account that the adjusting rod 3 itself has a loose structure due to the first guide channel 6 and the second guide channel 7, and there will be an obvious sense of discomfort when the medical staff holds it. Therefore, the gripping handle 30 is added to wrap the adjusting rod 3, so that the adjusting rod 3 has a tight structure and can appropriately increase the adjustment resistance of the adjusting rod 3. At the same time, the gripping handle 30 is made of transparent rubber material, and has a soft gripping feel, which can eliminate the sense of discomfort. In addition, the transparency also makes it convenient for medical staff to adjust the use length of the adjusting rod 3.

[0026] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
