[0034] Example 1

[0035] Reference Figure 1 , which is the first embodiment of the utility model, and this embodiment provides an adjustment mechanism.

[0036] The adjustment mechanism includes an adjustment assembly 100 .

[0037] Specifically, the adjustment component 100 includes a base 101, and a connecting column 102 is fixedly connected to the top of the base 101. Through the setting of the connecting column 102, the base 101 can be effectively engaged with the treatment component 200. A dredging hole 105 is opened at the center of the bottom of the base 101.

The connecting seat 201 and the limiting column 202 are both hollow, which is convenient for the jet freezing device to be sprayed into the treatment head core 103 through the treatment component 200, so as to realize the normal operation of liquid nitrogen cryotherapy.

[0039] Example 2

[0040] Reference Figure 2 , which is the second embodiment of the present utility model, is based on the previous embodiment, and is different from the previous embodiment in that: this embodiment provides a liquid nitrogen treatment head.

[0041] The treatment head core 103 includes nine divided surfaces.

[0042] Specifically, the treatment head core 103 is provided with nine dividing surfaces, and the nine dividing surfaces include a first dividing surface, a second dividing surface, a third dividing surface, a fourth dividing surface, a fifth dividing surface, a sixth dividing surface, a seventh dividing surface, an eighth dividing surface and a ninth dividing surface. The bottom of the treatment head core 103 is a starting surface N, and the starting surface N and the first dividing surface a are lofted to form a first end A, and the diameter of the first dividing surface a is 6 mm-5 mm. The starting surface N and the second dividing surface b are lofted to form a second end B, and the diameter of the second dividing surface b is 5 mm-4.5 mm. The starting surface N and the third dividing surface c are lofted to form a third end C, and the diameter of the third dividing surface c is 4.5 mm-4 mm. The starting surface N and the fourth dividing surface d are lofted to form a fourth end D, and the diameter of the fourth dividing surface d is 4 mm-3.5 mm. The starting surface N and the fifth dividing surface e are lofted to form a fifth end E, and the fifth dividing surface e The diameter is 3.5mm-3mm, the first end a-the fifth end e can select the end of the appropriate area for treatment according to the seborrheic keratosis diseases of different sizes, the starting surface N and the sixth dividing surface f are lofted to form the sixth end F, the diameter of the sixth dividing surface f is 3mm-2.5mm, which is mainly suitable for the treatment of flat warts, the starting surface N and the seventh dividing surface g are lofted to form the seventh end G, the diameter of the seventh dividing surface g is 2.5mm-2mm, which is mainly suitable for the treatment of sebaceous gland hyperplasia diseases, the starting surface N and the eighth dividing surface h are lofted to form the eighth end H, the diameter of the eighth dividing surface h is 2mm-1.5mm, which is mainly suitable for the treatment of flat warts, the starting surface N and the ninth dividing surface i are lofted to form the ninth end I, the diameter of the ninth dividing surface i is 1.5mm-1mm, which is mainly suitable for the treatment of skin tags, flat warts and milia diseases;

[0043] It is worth noting that the tumors that can be treated by the above-mentioned dividing surfaces are not limited to the above-mentioned ones. Different dividing surfaces can treat different sizes of the same tumor, or different sizes of different tumors, making the use of the dividing surfaces more comprehensive and more practical.

[0044] During specific use, before use, medical staff can first select a suitable dividing surface according to the size of the patient's tumor, and then use a special cutting tool to cut on the corresponding end, so that the dividing surface retained on the top of the treatment head core 103 can effectively fit the size of the patient's tumor, making the positioning of the treatment head core 103 more accurate, and it can be flexibly adjusted and used for small skin tumors on the patient's face or other parts, saving the steps of replacing different models of treatment head cores 103 back and forth, making the operation faster and more convenient, avoiding cross infection and reducing waste of consumables.

[0045] Example 3

[0046] Reference Figure 1-5, which is the third embodiment of the utility model. This embodiment provides an adjustment mechanism and a liquid nitrogen treatment head. Combined with the embodiment, it is easy to understand the working principle of the second embodiment:

[0047] Specifically, the base 101 has a diameter of 0.7 cm and a height of 0.5 cm, which is convenient for inserting into the connection seat 201 with a diameter of 1.5 cm. The connecting column 102 has a diameter of 0.6 cm and a height of 0.3 cm, which is convenient for inserting into the limiting column 202 with an inner diameter of 0.8 cm, so as to realize the limiting fixation of the entire treatment head core 103, making the treatment head core 103 more stable and firm during operation, and avoiding the phenomenon of the treatment head core 103 falling during use. The treatment head core 103 is an elastic structure, so that the treatment head core 103 can be smoothly ejected from the connection seat 201 and the limiting column 202.

[0048] It is worth noting that the limiting hole 204 opened on the top of the limiting column 202 has a diameter of 0.6 cm, which is smaller than the diameter of the bottom end of the treatment head core 103, effectively limiting and clamping the treatment head core 103 to prevent the treatment head core 103 and the connecting column 102 from slipping out during use.

[0049] When in use, first pass the elastic treatment head core 103 through the connecting seat 201 and the limiting column 202, so that the base 101 and the connecting column 102 at the bottom of the treatment head core 103 are limited by the connecting seat 201 and the limiting column 202 respectively, thereby fixing the treatment head core 103, which is convenient for the treatment head core 103 to be operated better. After use, only the entire end surface of the treatment head core 103 needs to be cut off from the top of the connecting column 102 to separate the treatment head core 103 from the connecting column 102, and then the connecting column 102 and the bottom base 101 are taken out from the bottom of the treatment component 200 to separate the adjustment component 100 from the treatment component 200. When used next time, only the adjustment component 100 with the new treatment head core 103 needs to be replaced, which saves the steps and time of replacing the treatment component 200.
