Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field especially is related to a passageway instrument for spinal operation. BACKGROUND

[0002] As one of the important methods for treating spinal diseases, spinal surgery is also constantly evolving. In the past, spinal surgery often required a large incision and extensive tissue dissection, which brought great trauma and long recovery time to patients. However, minimally invasive surgery has higher requirements for surgical tools, which need to have precise positioning, stable support and flexible operation performance. A passageway instrument for spinal surgery is developed under such technical background to meet the special needs of spinal minimally invasive surgery for surgical tools.

[0003] The existing patent with the patent number CN216021201U discloses a passageway instrument for spinal surgery, which includes a shell, and a box body adjacent to the right side of the shell. An adjusting mechanism is provided on the inner wall of the box body. The adjusting mechanism includes an arc slot, a ball, a roller, a vertical plate and a threaded rod. The outer side of the arc slot is connected with the inner wall of the box body. The inner wall of the arc slot is slidingly connected with the outer wall of the ball. The outer wall of the ball is slidingly connected with the outer wall of the roller. The front end surface of the roller is rotatably connected with the rear end surface of the vertical plate through a pin shaft. The front end surface of the vertical plate is rotatably connected with the inner wall of the box body through a rotating shaft. By rotating the right threaded rod in the adjusting mechanism, a part of the right threaded rod is rotated out, and at the same time, the left threaded rod is rotated in. The left threaded steel pushed by the rotating-in left threaded rod moves the ball to the right. The right-moving ball pushes the roller to move. The moving roller drives the expansion mechanism on the vertical plate to rotate, maintaining the angle of the passageway instrument and accelerating the work efficiency.

[0004] The existing passageway instrument for spinal surgery mainly has the problem of difficult disinfection. The tool has a complex structure, including a shell, a box body, an adjusting mechanism, a lifting mechanism and many other components. There are many gaps and corners between the components. For example, the gaps between the arc slot and the ball in the adjusting mechanism, the gaps between the roller and the vertical plate, and the connection between the shell and the box body. These parts are easily contaminated with blood, tissue fluid and other pollutants during the operation. However, due to the complexity of the structure, it is difficult to completely remove the dirt and bacteria in these parts by conventional disinfection methods. The residual bacteria may cause infection, posing a great risk to the patient. In addition, the complex structure may also make the disinfection process cumbersome, increasing the disinfection time and cost, and affecting the efficiency and arrangement of the operation. Therefore, we propose a passageway instrument for spinal surgery to solve the above-mentioned problems. UTILITY MODEL CONTENTS

For example, the gap between the arc groove and the ball in the adjusting mechanism, the gap between the roller and the vertical plate, and the connecting part of the shell and the box. These parts are extremely easy to contaminate blood, tissue fluid and other pollutants during the operation. And when disinfecting, due to the complexity of its structure, it is difficult to completely remove the dirt and bacteria in these parts by conventional disinfection method, and the residual bacteria may cause infection, which brings great risk to the patient. In addition, the complex structure may also cause the disinfection process to be complicated, increase the disinfection time and cost, and affect the efficiency and arrangement of the operation. The utility model discloses a channel tool for spinal surgery,

[0024] The support 1 is fixedly installed with the first sub support 2 and the second sub support 3 in front, the first sub support 2 is located above the second sub support 3, the base 4 is fixedly installed on the first sub support 2 and the second sub support 3, the first sliding rail 5 is fixedly installed in front of the base 4, the second sliding rail 6 is fixedly installed left of the base 4, the third sliding rail 7 is fixedly installed right of the base 4, and the first support frame 8 and the second support frame 9 are movably installed on the first sliding rail 5. By fixedly installing the first sub support 2 and the second sub support 3 in front of the support 1, installing the base 4 with multiple sliding rails on the sub support 1, and movably installing the first support frame 8 and the second support frame 9 on the first sliding rail 5, the channel tool can be flexibly adjusted in position and angle according to different operation requirements during the operation, so as to more accurately reach the operation site, provide greater convenience and higher accuracy for operation, and help to improve the success rate and safety of the operation.

[0025] The first support frame 8 is located directly to the left of the second support frame 9. A first spreader 10 is fixedly installed on the first support frame 8. A first fixing screw 11 and a second fixing screw 12 are fixedly installed directly above the first spreader 10. The first fixing screw 11 and the second fixing screw 12 are fixed to the first support frame 8. By fixing the first spreader 10 on the first support frame 8 and arranging the first fixing screw 11 and the second fixing screw 12 directly above it for stabilization, the corresponding part can be accurately and stably spread during the operation, providing the doctor with a clearer surgical field of view and operating space, thereby ensuring the smooth progress of the operation and improving the safety and efficiency of the operation.
