Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, in particular to a lower lip positioning fixture used in lower lip tumor excision surgery. Background Art

[0002] During medical examinations and treatments in the Department of Dentistry, it is often necessary to examine and treat the inner side of the patient's lower lip. For example, in the removal of a lower lip tumor (such as a cyst), it is usually necessary to turn the patient's lower lip over and anesthetize it, and then remove the small tumor.

[0003] In the existing surgical operation method, the assistant needs to pinch the two sides of the lower lip with his hands and put his hands on the outside of the lower lip to achieve the lower lip eversion and the small tumor lifting. This method not only reduces the probability of bleeding, but also facilitates the doctor's operation, but still has the following disadvantages: First, the doctor's surgical operation space is limited, which affects the efficiency of lower lip tumor removal; second, cutting small tumors requires sharp tools (such as blades), and sutures are required after cutting, which is easy to accidentally injure the assistant. Therefore, it is urgent to study a lower lip positioning fixture for lower lip tumor removal surgery to solve the above problems. Utility Model Content

[0009] As a preferred technical solution of the present invention, a connecting rod is vertically fixed to an edge of the support strip away from the lower lip pressing portion; and a handle is fixed to an end of the connecting rod away from the support strip.

[0010] As a preferred technical solution of the present invention, a telescopic rod is arranged between the two upper clamping strips; one end of the telescopic rod is connected to the supporting strip; and the other end of the telescopic rod has an affected part lifting portion.

[0011] As a preferred technical solution of the present invention, the telescopic rod includes a rod barrel; a movable rod is slidably inserted into one end of the rod barrel; the affected part lifting portion is arranged on the end of the movable rod away from the rod barrel; a side connection sleeve is radially fixed to one end of the rod barrel; the inner thread of the side connection sleeve is matched with a limiting column; one end of the limiting column can be in conflict with the outer wall of the movable rod.
