Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a multifunctional minimally invasive channel dilator for unilateral double-channel spinal endoscopic surgery. Background Art

[0002] With the continuous development of medical technology, minimally invasive surgery has become the main trend in the treatment of many diseases. In the treatment of spinal diseases, unilateral double-channel spinal endoscopic surgery has gradually been widely used due to its advantages such as less trauma and faster recovery.

[0003] The utility model with the existing authorization announcement number CN218279713U discloses a multifunctional minimally invasive channel expander for unilateral dual-channel spinal endoscopic surgery, including a guide rail, a sliding sleeve, a connecting sleeve, a fixing bar, a water baffle, a moving mechanism and a positioning mechanism. The sliding sleeve is mounted on the guide rail and can slide left and right. The guide rail is provided with convex teeth. The connecting sleeve is fixedly arranged at the end of the sliding sleeve and is mounted on the sliding rail. The fixing bar is fixedly arranged at the end of the sliding sleeve. The water baffle is fixedly arranged at the end of the fixing bar. The moving mechanism is arranged at the end of the sliding sleeve. The positioning mechanism is fixedly arranged in the middle of the sliding sleeve. The sliding sleeve, the fixing bar and the water baffle are each provided in two groups.

[0004] According to the above technical solution, the water baffle is inserted into the incision, and the moving mechanism drives the sliding sleeve and the water baffle to move, thereby expanding the micro-incision to form a natural and smooth channel. After the expansion is completed, the water baffle is limited and fixed by the positioning mechanism. While maintaining the minimally invasive small incision, the soft tissue around the channel can be expanded to reduce muscle damage, and a very smooth water flow flushing channel is achieved. The overall structure is simple, the operation is convenient, and the practicality is strong; it includes a guide rail, a sliding sleeve, a connecting sleeve, a fixing bar, a water baffle, a moving mechanism and a positioning mechanism. The sliding sleeve is mounted on the guide rail and can slide left and right. The guide rail is provided with convex teeth. The connecting sleeve is fixedly arranged at the end of the sliding sleeve and is mounted on the sliding rail. The fixing bar is fixedly arranged at the end of the sliding sleeve. The water baffle is fixedly arranged at the end of the fixing bar. The moving mechanism is arranged at the end of the sliding sleeve. However, during use of the above technical solution, the expansion distance of the minimally invasive small incision cannot be accurately measured and calculated, which easily causes the expansion distance of the minimally invasive small incision to be too large or too small, which not only affects the efficiency of the operation, but also causes unnecessary harm to the patient, further reducing the use effect of the device.

[0005] Therefore, those skilled in the art provide a multifunctional minimally invasive channel dilator for unilateral dual-channel spinal endoscopic surgery to solve the problems raised in the above background technology. Utility Model Content

The trapezoidal blocks 4 can be used to fix the controller 203 to avoid the problem of shaking of the controller 203 during use.

[0024] The bottom surface of the fixed seat 1 is fixedly connected with a telescopic rod 205 and two buffer springs 202, and the outer surface of each buffer spring 202 is fixedly connected with a reinforcing gasket 5. The bottom end of each reinforcing gasket 5 is fixedly connected to the upper surface of the fixed box 201. The buffer spring 202 can be fixed by using the reinforcing gasket 5 to avoid the problem of fluctuation of the buffer spring 202 during use.

[0025] The bottom end of each buffer spring 202 is fixedly connected to the upper surface of the fixed box 201. Two groups of bolts 6 are provided below the fixed base 1. The top end of each group of bolts 6 passes through the fixed base 1 and extends to the top of the fixed base 1. The outer surface of each group of bolts 6 is threadedly connected to the inner wall of the fixed base 1. The bolts 6 can be used to fix the fixed base 1 to avoid the problem of shaking of the fixed base 1 during use.

[0026] The inner wall of the fixed box 201 is rotatably connected to a bidirectional threaded rod 209, and the outer surface of the telescopic rod 205 is fixedly connected to a fixing ring 3. The bottom end of the fixing ring 3 is fixedly connected to the upper surface of the fixed box 201. The fixing ring 3 can be used to reinforce the telescopic rod 205 to avoid the problem of tilting of the telescopic rod 205 during use.

[0027] The inner wall of the bidirectional threaded rod 209 is threadedly connected to two fixing frames 206, and the outer surface of the bidirectional threaded rod 209 is fixedly connected to a bearing 7. The outer surface of the bearing 7 is threadedly connected to the inner wall of the fixing box 201. The use of the bearing 7 can increase the stability of the bidirectional threaded rod 209 during the rotation process, thereby avoiding the problem of instability of the bidirectional threaded rod 209 during the rotation process.

[0028] A stabilizing plate 212 is provided under each fixing frame 206, and the inner wall of each stabilizing plate 212 is threadedly connected to the inner wall of the fixing frame 206 with two groups of screw nails 207, and the interior of each stabilizing plate 212 is fixedly connected to an expansion clamp 204, the inner wall of one fixing frame 206 is fixedly connected to an infrared ranging sensor 208, and the inner wall of another fixing frame 206 is fixedly connected to a reflective disk 211, and the right end of the bidirectional threaded rod 209 is fixedly connected to a fixing disk 210, and the outer surface of each fixing frame 206 is slidably connected to the interior of the fixing box 201, and the outer surface of the fixing disk 210 is fixedly connected to a handle 8, which is convenient for the staff to drive the fixing disk 210 to rotate, thereby further improving the rotation frequency of the bidirectional threaded rod 209.

[0029] The working principle of the present invention is as follows: when in use, first connect the telescopic rod 205, the controller 203 and the infrared ranging sensor 208 to the power supply. When using the device, the staff uses the bolt 6 to fix the fixing seat 1 to the surgical frame, and then uses the controller 203 to control the telescopic rod 205 to extend and retract, thereby adjusting the height position of the separation structure composed of the fixing box 201, the expansion clamp 204 and the controller 203. When the bottom end of the expansion clamp 204 is adjusted to a suitable position, the controller 203 is used to control the telescopic rod 205 to stop extending and retracting, and the bottom end of the expansion clamp 204 is inserted into the patient's skin incision. Then, the staff holds the handle 8 and applies a force to the fixing plate 210. The fixing plate 210 then drives the bidirectional threaded rod 209 to rotate under the support of the fixing box 201. Since the bidirectional threaded rod 209 is threadedly connected to the fixing frame 206, The rotation of the bidirectional threaded rod 209 enables the fixing frame 206 to slide along the inside of the fixing box 201, thereby adjusting the distance between the fixing frames 206. The fixing frames 206 drive the movement of the distance between the expansion clamps 204 to achieve the purpose of expanding the minimally invasive small incision. During the rotation of the bidirectional threaded rod 209, the infrared transmitter in the infrared ranging sensor 208 continuously emits infrared rays to the reflective disk 211. The infrared rays are reflected by the reflective disk 211. The infrared signals after emission are received by the infrared receiver in the infrared ranging sensor 208, thereby measuring the distance between the two fixing frames 206, making it convenient for medical staff to control the size of the minimally invasive small incision, and avoiding the traditional device, which is prone to causing the expansion distance of the minimally invasive small incision to be too large or too small due to the inability to accurately measure and calculate the minimally invasive small incision, further reducing the use effect of the device.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
