Description

TECHNICAL FIELD

[0001] The utility model relates to gum separator technical field, especially a gum separator of multi -angle adjustable. BACKGROUND

[0002] In oral surgery, gum separator is a commonly used tool for gum tissue separation. In the operation process such as periodontal surgery, implant surgery, etc., the doctor needs to use the gum separator to accurately separate the gum tissue to expose the operation area and ensure the smooth progress of the operation.

[0003] At present, the common gum separator structure on the market is relatively fixed, and the cutter head and handle are usually fixedly connected, and the angle is not adjustable. In actual operation, due to the difference of oral anatomy structure of different patients, such as the shape, position and depth of the gum, the doctor needs to constantly adjust the holding posture to change the direction of the separator cutter head to adapt to different operation requirements. This operation method has many disadvantages: on the one hand, frequent adjustment of holding posture is easy to cause fatigue of the doctor's hand, affect the stability and accuracy of operation, and thus may reduce the operation efficiency; on the other hand, the cutter head with fixed angle is difficult to completely fit the gum tissue of the patient, which may cause unnecessary pulling or damage to the surrounding normal tissue in the separation process, increasing the operation risk and the pain of the patient.

[0004] Therefore, it is necessary to design a simple structure, easy to adjust, multi-angle adjustable gum separator. SUMMARY

[0009] The cutter body is hinged on the anti-touch part;

[0010] The threaded sleeve is arranged in the handle through the damping bearing; and

[0011] The screw rod is arranged on the threaded sleeve and can rotate with the threaded sleeve and move along the handle in the axial direction;

[0012] The push rod is fixed to the end of the screw rod and extends into the extension part;

[0013] The connecting rod is hinged between the push rod and the cutter body.

[0014] When the handle is in a stationary state, the cutter body can rotate around the hinge axis to adjust the relative angle with the patient's gum.

[0015] As a preferred embodiment of the multi-angle adjustable gum separator, the cutter body comprises a linkage rod and a separation head, and the included angle between the linkage rod and the separation head is 120-160°.

[0016] As a preferred embodiment of the multi-angle adjustable gum separator, the distance from the end of the separation head to the hinge axis with the anti-scratching part is 2-3 times the distance from the end of the linkage rod to the hinge axis.

[0017] As a preferred embodiment of the multi-angle adjustable gum separator, an inclined edge is arranged on the separation head to improve the sharpness of the front end of the separation head.

[0018] As a preferred embodiment of the multi-angle adjustable gum separator, an opening is arranged at the central position of the handle, a hand wheel is arranged on the threaded sleeve, and the hand wheel is located in the opening.

[0019] As a preferred embodiment of the multi-angle adjustable gum separator, anti-slip stripes are arranged on both sides of the opening of the handle.

[0020] The beneficial effects of the present application are as follows: the adjustable cutter body can keep the handle stationary, and the doctor can adjust the relative angle between the cutter body and the patient's gum in the oral surgery to adapt to the anatomical structure of different patients' mouths and the operation requirements, thereby improving the accuracy and efficiency of the operation.
