[0002] Thyroid and breast surgery is a surgical treatment specifically for thyroid and breast diseases. The scope of this type of surgery is wide, including but not limited to the removal of thyroid tumors, subtotal or total thyroidectomy, removal of benign breast tumors, radical mastectomy for breast cancer, etc.

[0003] When performing thyroid and breast surgery, the doctor will develop a personalized surgical plan based on the patient's specific condition, such as the size, location, and nature of the tumor, as well as the patient's physical condition. During the operation, the doctor will preserve normal tissue as much as possible to reduce damage to the patient's body. The most commonly used medical device in thyroid and breast surgery is the hemostatic stick. The working end of a traditional hemostatic stick is only equipped with an electrode head to achieve hemostasis. This type of hemostatic stick cannot obtain real-time images of the hemostatic tissue, resulting in low efficiency and accuracy when the doctor operates. Utility Model Content

When the electrical connection port 4 is powered, the electrode head 3 will obtain a high-frequency current, thereby being able to stop bleeding on the tissue. This principle is a prior art, so it will not be described in detail here;

[0037] A camera 5 is embedded on the working end surface of the rod body 2, and a signal interface 6 electrically connected to the camera 5 is provided at the tail end of the handle 1. During the hemostatic process using the hemostatic rod, a real-time image of the hemostatic tissue can be obtained through the camera 5 to improve the efficiency of the doctor's operation and the accuracy of the hemostatic operation;

[0038] There is a suction channel 210 in the rod body 2, one end of the suction channel 210 passes through the end face of the working end of the rod body 2, and the other end of the suction channel 210 is connected to the suction connector 7 on the handle 1. The suction connector 7 can be connected to a suction device. During the hemostatic operation, the suction device can be turned on to suck away smoke, bleeding, exudate or pus, thereby facilitating the improvement of the clarity of the surgical field of view, improving the efficiency of the surgical operation and the accuracy of the hemostatic operation. The diameter of the working end of the rod body 2 is 2mm to 3mm.

[0039] Example 2

[0040] like Figure 1 , Figure 5 As shown, this embodiment is a further improvement on the basis of embodiment 1, and the details are as follows:

[0041] The working end of the rod body 2 is bent toward one side, and the bending part is in an arc shape, which is convenient for insertion into the body for operation. There is a certain angle with the doctor's line of sight, which will not hinder the surgical field and facilitate the doctor to perform surgery. Normally, the bending angle of the working end of the rod body 2 is preferably 15° to 25°.

[0042] Example 3

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this embodiment is a further improvement on the basis of embodiment 2, and the details are as follows:

[0044] The front end of the handle 1 is connected to the rear end of the rod 2 through an adjustment mechanism 8, and the adjustment mechanism 8 can realize locking the rod 2 (the rod 2) after rotating it at any angle within a range of 360° around the axis. During the operation, the doctor can adjust the direction of the working end of the rod 2 according to his own surgical habits;

[0045] A plug connector 220 connected to the suction channel 210 is provided at the center of the rear end of the rod body 2, and a plug hole 110 connected to the suction connector 7 is provided at the center of the front end of the handle 1. The plug connector 220 is inserted into the plug hole 110. Since the rod body 2 is designed to be rotated at any angle within a range of 360° around the axis, in order not to affect the suction operation at this time, the above-mentioned specific structure is designed to avoid interference between the rotation and the suction operation.

[0046] Example 4

[0047] like Figure 2 , Figure 4 As shown, this embodiment is a further improvement on the basis of embodiment 3, and the details are as follows:

[0048] The adjusting mechanism 8 includes: a screw sleeve 810, a first external thread segment 820 arranged on the front end of the handle 1, and a second external thread segment 830 arranged on the rear end of the rod body 2. The two ends of the screw sleeve 810 are respectively threadedly connected with the first external thread segment 820 on the handle 1 and the second external thread segment 830 on the rod body 2. When changing the direction of the working end of the rod body 2, it is only necessary to loosen the screw sleeve 810, adjust the direction, and then re-tighten it. The structure is simple and the operation is very convenient.

[0049] Of course, in actual application, other structures are not excluded. For example, a petal structure is used as the adjustment mechanism 8, the nut of the petal structure is loosened, and then the direction of the rod body 2 in the multi-petal chuck of the petal structure is adjusted, and finally the nut is retightened. This operation method is also very convenient.

[0050] Example 5
