Abstract

[Purpose of the item]; This designed item is a limiting device for osteotomy surgery, which can prevent over-cutting during osteotomy surgery to avoid damaging unplanned bone or soft tissue resection. ;[Design Description];Please refer to the three-dimensional view of this design. Its appearance is characterized by the structure of a clamp: its bottom has a guide part on which other components of the device are formed, and a blocking part is formed on the guide part. The rear end is in the shape of a protrusion, and the rear and front ends of the baffle part present a continuously changing stepped surface. The bottom edge of the guide part is provided with a through slot so that an osteotome or a bone saw can be inserted to form a sliding The sleeve-like structure allows the osteotomy surgery limiter of this design to slide forward and backward and be fixed to the position of the bone saw or osteotome as needed, so that when the osteotomy operation is performed, when the depth of the bone saw or osteotome reaches the required When the bone saw or osteotome is cut into the bone, the baffle part blocks the remaining part cut into the bone, thereby preventing the bone saw or osteotome from continuing to penetrate further, thereby achieving the purpose of avoiding over-cutting the bone. No matter from any angle, this design gives people a practical feeling as a whole. It has novel visual effects and creativity.

Description

Osteotomy limiter

This design item is an osteotomy limit device that prevents overcutting during osteotomy to avoid injury to bone or soft tissue outside the resection plan.

Please refer to the perspective view of the design, which is characterized by the structure of the clamp: a bottom portion has a guide portion on which the other components of the device are formed, and a stopper portion is formed at the rear end of the guide portion and has a protrusion shape. The rear end and the front end of the blocking portion present a continuously changing step surface, and the bottom edge of the guiding portion is provided with a through groove for inserting the osteotome or the bone saw to form a sliding sleeve-like structure, so that The osteotomy surgical limiter of this design can be slid back and forth and fixed to the position of the bone saw or osteotome as needed, so that when the osteotomy is performed, when the depth of the bone saw or osteotome is reached, The remaining portion of the cut bone is caught by the flap portion to prevent the bone saw or the osteotome from continuing deep enough to achieve the purpose of avoiding overcutting the bone according to the present invention. The design of the design from any angle, the overall practical experience, has a novel visual effect and creativity, but also has a practical function, in line with the requirements of the design patent application. The above description is only for the purpose of assisting in the understanding of the creation and not to limit its content; it should be understood that the design is based on the drawings.
