Description

Periosteum blunt separator

Technical Field

The utility model belongs to the technical field of medical instrument device, especially with a blunt nature separator of periosteum.

Background

Need peel off nasal bone periosteum among the nasal surgery, the tradition is all through the separation that scissors from up carrying on nasal bone periosteum from the bottom, just can only follow cartilage part to the hard bone part, has the key stone district just also to be the ligament part in the middle of two cartilages and hard bone, and the ligament part is because toughness is big, difficult separation, and traditional scissors only can cut it and then down operate, must lead to bleeding many like this, and the tissue wound is big, and the patient recovery time is longer. In addition, because the traditional apparatus has no force point when in use, the deep part is difficult to separate, the deep part can not be jointed with periosteum for separation, and further the non-jointing of the prosthesis during the implantation can be caused, and the instability of the prosthesis can be caused.

SUMMERY OF THE UTILITY MODEL

To the problem that above-mentioned background art exists, the utility model provides a blunt sex separator of periosteum.

Therefore, the utility model adopts the following technical scheme: the periosteum passive separator comprises a scissor type separator formed by movably connecting two operating rods through a pin shaft, and is characterized in that the top of each operating rod is provided with a blade part, the blade parts are arranged on the outer sides of the tops of the operating rods, the blade parts are obliquely and downwards arranged to form a certain included angle with the corresponding operating rods, and the directions of the two blade parts are opposite to each other to form a positive blade and a negative blade;

the periosteum passive separator also comprises an angle positioning and adjusting mechanism, the angle positioning and adjusting mechanism comprises a guide block and a fixed rod, the guide block is arranged at the inner side part of the lower end of one of the operating rods, and the guide block is provided with an arc-shaped guide hole; the inner side part of the lower end of the other operating rod is provided with a transverse extending part, the transverse extending part is provided with a penetrating hole for penetrating a fixing rod, the fixing rod penetrates into the penetrating hole after passing through the arc-shaped guide hole, and the opening angle of the operating rod can be set by the fixing rod according to the width of the nasal bone of different patients.

When the operating rod is used, the front edge and the back edge at the top of the operating rod have a positive angle, the positive direction is a closed state from the cartilage part to the hard bone part from bottom to top, then the hard bone part is torn back to the cartilage area from the reverse direction, and the main body is in an open state. The product can be pulled downwards along with the bone from the hard bone part, has an acting point along with the hard bone so as to carry out deeper separation, and can naturally bleed less without shearing ligaments, and has less bruise and swelling. And because the prosthesis can be pulled down along with the bone, the stripping depth is deeper, the prosthesis can be better fitted and more stable, and the operation effect is better.

The center of the center line forming the arc-shaped guide hole faces to the upper part of the periosteum blunt separator.

The fixing rod is a screw, and the penetrating hole is a threaded hole.

The blade part and the operating rod are integrally formed.

The guide blocks are integrally formed with the corresponding operating rods, and the transverse extending portions are integrally formed with the corresponding operating rods.

The bottom of the operating rod is provided with an operating handle.

The guide block is provided with a scale, the numerical value of the scale is a length display table with the angle or the centimeter as a unit, the angle display table is used for displaying the opening angle of the operating rod, and the centimeter number can be used for adjusting according to the width of the nasal bone of each patient and recording the stripping size.

The utility model discloses following beneficial effect can be reached: 1. the utility model discloses a separation periosteum is peeled off with reverse to forward, avoids haring the nerve, and is little to the tissue wound. 2. The front and back edges at the top of the operating rod have a positive angle, and the positive direction is a closed state from the cartilage part to the hard bone part from bottom to top, and then the hard bone part is torn back to the cartilage area from the hard bone part, and the main body is in an open state. The product can be pulled downwards along with the bone from the hard bone part, has an acting point along with the hard bone so as to carry out deeper separation, and can naturally bleed less without shearing ligaments, and has less bruise and swelling. And because the prosthesis can be pulled down along with the bone, the stripping depth is deeper, the prosthesis can be better fitted and more stable, and the operation effect is better.
