[0002] After the cervix has cervical epithelial damage, necrosis, exfoliation or even erosion, it is necessary to treat the cervix in a short period of time. The common method is to take medicine for treatment. This treatment method has a slow recovery and a long treatment cycle for the cervix, which is not conducive to the healing of the affected area. Especially when erosion occurs, drug treatment becomes even more ineffective. In addition, when the existing treatment instrument treats the affected area, due to the small operable space of the affected area, medical staff need to carefully adjust the angle and position of the treatment instrument to perform fine treatment on the affected area. The long-term manual fine operation brings a great workload to gynecological medical staff. Therefore, there is room for improvement in view of the above problems. Content of the Utility Model

[0003] The utility model provides a cervical treatment instrument, which can solve the problem that the existing treatment instrument does not have an angle adjustment function and medical staff need to manually adjust the treatment angle by themselves. The specific implementation is as follows:

[0025] Combined Figures 1 to 3 , the present application provides a cervical treatment instrument, including a treatment part and a treatment main body 1. The treatment part includes a treatment rod 3 and a treatment head 4 arranged at the top of the treatment rod 3 for performing cryotherapy or thermocautery on the surface of the affected area. A driving mechanism is arranged in the treatment main body 1, the treatment rod 3 is connected to the driving mechanism and rotates under the drive of the driving mechanism. The normal central axis b of the treatment head 4 is arranged parallel to but not coincident with the rotation central axis a of the treatment rod 3, which makes the treatment head 4 deviate from the rotation central axis a of the treatment rod 3. When the treatment rod 3 rotates, it can drive the whole treatment head 4 to rotate around the rotation central axis a of the treatment rod 3. Without moving the treatment main body 1, by controlling the rotation of the treatment rod 3, the movement range of the treatment head 4 is increased, so that a larger area of the affected area can be treated.

[0026] Figure 3 An implementation manner of the treatment rod 3 of the present application is given. In this embodiment, the treatment rod 3 is set to be arc-shaped. According to the actual situation, the treatment rod 3 can be bent from the position close to the treatment main body 1 of the treatment rod 3 to form the arc-shaped treatment rod 3, or the treatment rod 3 can be bent from the position close to the treatment head 4 of the treatment rod 3. The arc-shaped treatment rod 3 makes the treatment head 4 arranged at its top deviate from the rotation central axis a of the treatment rod 3. When the treatment rod 3 rotates around its rotation central axis a, it drives the whole treatment head 4 to rotate and move around the rotation central axis a.

[0027] Figure 4Another embodiment of the treatment rod 3 of the present application is given. The present application includes a treatment main body 1; a treatment rod 3, and a treatment head 4 provided at the end of the treatment rod 3. Among them, the treatment rod 3 forms a bending portion in the direction close to the treatment head 4, and the bending portion can make the central axis b of the treatment head 4 deviate from the rotation central axis a of the treatment rod 3. When the treatment rod 3 rotates, it can drive the treatment head 4 to rotate integrally around the rotation central axis a of the treatment rod 3 to treat the affected area in the region centered on the rotation central axis a. Thus, without the treatment main body 1 moving, by controlling the rotation of the treatment rod 3, the purpose of increasing the treatment area is achieved, and then it is convenient to perform fine treatment on the affected area of the patient and improve the treatment effect.

[0028] Preferably, the outer contour of the treatment head 4 is set to be circular. The distance between the rotation central axis a of the treatment rod 3 and the normal central axis b of the treatment head 4 is the radius of the circle. Let the radius of the circular outer contour of the treatment head 4 be r, that is, the distance between the rotation central axis a of the treatment rod 3 and the normal central axis b of the treatment head 4 is the radius r of the circle. When the treatment rod 3 rotates around the rotation central axis a, it drives the treatment head 4 to rotate synchronously around the central axis a, thereby forming a circular or fan-shaped plane treatment area with a radius of 2r. Without the treatment main body 1 moving, by controlling the rotation of the treatment rod 3, the affected area within the circular or fan-shaped plane area with a radius of 2r can be treated.

[0029] In addition, the driving mechanism can be set to include a motor base 5 provided in the treatment main body and a driving unit provided on the motor base 5. The treatment main body is formed with a receiving cavity, and both the motor base 5 and the driving unit are provided in the receiving cavity. The driving unit includes a motor 6 and a speed reducer 7, and the motor 6 is connected to the speed reducer 7.

[0030] In another embodiment of the present application, a rotary joint portion 2 is provided between the treatment main body 1 and the treatment rod 3, and a coupling 8 is provided at the connection between the driving unit and the rotary joint portion 2. The rotary joint portion 2 and the treatment main body 1 are set to be detachably connected. During operation, the motor 6 and the speed reducer 7 are turned on to drive the treatment rod 3 and the treatment head 4 to rotate, thereby realizing all-round treatment of the affected area of the patient.

[0031] In another embodiment of the present application, the treatment main body 1 is provided with a limiting groove 11, and the treatment rod 3 is correspondingly provided with a limiting protrusion 31. The limiting protrusion 31 is arranged in the limiting groove 11 and is rotatably connected along the limiting groove 11. During operation, the driving mechanism drives the treatment rod 3 to rotate. At the same time, the limiting protrusion 31 rotates along the limiting groove 11, which can play the role of stabilizing the treatment rod 3.

[0032] Specifically, a control unit and a storage battery are respectively provided in the treatment main body 1. The control unit is electrically connected to the storage battery. The storage battery provides electrical energy for the treatment main body 1, and the control unit is electrically connected to the driving mechanism and can control the operation of the driving mechanism.

[0033] When the present application is in operation, medical staff hold the treatment main body 1 and preheat the therapeutic instrument. After reaching the required temperature, the treatment head 4 and part of the treatment rod 3 are inserted into the patient's body for treatment. The condition of the affected area of the patient can be seen through an external imaging display. When large-area treatment of the affected area is required, the control unit controls the motor 6 and the speed reducer 7 to start, driving the treatment rod 3 to rotate. Since the central axis of the treatment head 4 deviates from the central axis of the treatment rod 3, the treatment head 4 can rotate around the central axis of the treatment rod 3. For the affected area within the rotation and movement range of the treatment head 4, medical staff do not need to manually fine-tune the angle or position of the treatment main body. They only need to control the motor 6 and the speed reducer 7 to rotate the treatment head 4 to the target position, and then the affected area can be treated, thus realizing all-round and precise treatment of the patient's affected area and improving the treatment effect.

[0034] Many other changes and modifications can be made without departing from the concept and scope of the present utility model. It should be understood that the present utility model is not limited to a specific embodiment, and the scope of the present utility model is defined by the appended claims.
