Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a single-sided dual-channel endoscopic surgical locking cavity dilation tube. Background Technology

[0002] Endoscopic targeted cavity dilatation tubes have extremely important applications in the medical field, especially in endoscopic surgery, significantly improving the precision, safety, and efficiency of the procedure.

[0003] In existing technologies, traditional step-by-step expansion tubes, due to their lack of slotted design, will push away the tip of the first-stage guide rod in the observation channel during step-by-step insertion, causing the target point to shift. This requires repeated positioning during the operation, increasing operational risks and time costs. Utility Model Content

The tertiary dilation tube, the quaternary dilation tube, and the sixth dilation tube are provided with first slots at symmetrical positions at both ends. The sixth dilation tube and the sixth dilation tube are provided with a second slot of the same width as the tertiary dilation tube, the quaternary dilation tube, and the sixth dilation tube on one side.

[0008] Furthermore, an improvement of this utility model is that the length of the first empty slot is 2 cm.

[0009] Furthermore, the improvement of this utility model is that the expansion tube is used in unilateral dual-channel endoscopic surgery, through the operation incision to insert the first-level guide rod step by step, and the slot of the expansion tube is directly opposite the first-level guide rod in the observation incision, so that the tip of the first-level guide rod is embedded in the slot to lock the meeting point of the observation channel and the operation channel.

[0010] (III) Beneficial Effects

[0011] Compared with the prior art, this utility model provides a unilateral dual-channel endoscopic surgical locking cavity dilation tube, which has the following beneficial effects:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5The single-sided dual-channel endoscopic surgical locking cavity dilation tube of this utility model includes a secondary dilation tube 2, a tertiary dilation tube 3, a quaternary dilation tube 4, a quinary dilation tube 5, a sixth dilation tube 6, and two primary guide rods 1. The secondary dilation tube 2, the tertiary dilation tube 3, and the quaternary dilation tube 4 are provided with first grooves 7 at symmetrical positions at both ends. The quaternary dilation tube 5 and the sixth dilation tube 6 are provided with a second groove 8 with the same width as the secondary dilation tube 2, the tertiary dilation tube 3, and the quaternary dilation tube 4 on one side.

[0023] In this embodiment, the length of the first empty slot 7 is 2 cm.

[0024] In this embodiment, the expansion tube is used in unilateral dual-channel endoscopic surgery to gradually expand and insert the primary guide rod 1 through the operating incision, with the slot of the expansion tube facing the primary guide rod 1 in the observation incision, so that the tip of the primary guide rod 1 is embedded in the slot to lock the meeting point of the observation channel and the operating channel.

[0025] In unilateral dual-channel endoscopic surgery, the procedure is performed according to the unilateral dual-channel endoscopic technique (UBE):

[0026] The first step involves bringing the two primary guide rods 1 together at the surgical target location on the spinal bone surface through both the observation incision and the operating incision. Next, the designed 2-6 level locking target cavity expansion tube is inserted through the operating incision, passing through the primary guide rods 1 and gradually expanding the tube. During this process, it is crucial to ensure that the slot of the expansion tube is directly aligned with the primary guide rod 1 within the observation incision, and that the tip of the primary guide rod 1 is precisely embedded within the slot of the 2-6 level locking target cavity expansion tube.

[0027] The second step involves inserting the outer sheath of the UBE endoscope through the observation incision to reach the primary guide rod 1. Then, remove the primary guide rod 1 and place the UBE endoscope at the target site. At this point, the primary guide rod 1 and the 2-6 level slotted dilatation tubes (secondary dilatation tube 2, tertiary dilatation tube 3, quaternary dilatation tube 4, quinary dilatation tube 5, and sixth dilatation tube 6) inserted through the incision can be clearly observed. Next, remove the primary guide rod 1 and the 2-5 level slotted dilatation tubes from the incision, leaving the 6th level slotted dilatation tube in place, and then insert the UBE ablation electrode.

[0028] Precise target positioning: Traditional step-by-step expansion tubes, without grooves, push away the first-stage guide rod 1 of the observation channel during insertion, causing the target position to shift. This expansion tube, however, features a grooved design, allowing the tip of the first-stage guide rod 1 of the observation channel to embed into the groove, locking the convergence point of the observation and operating channels at the target point. This prevents target displacement, solves the problem of repeated intraoperative positioning, and reduces the risk of iatrogenic injury.

[0029] Optimized surgical field of view: Traditional dilators often cause soft tissue to obstruct the surgical field of view, leading to blind operations. This dilator retains the sixth-level slotted dilator, and its single-sided through groove can push away soft tissue to form an unobstructed field of view, making the cavity site open and clear, and reducing blind and repetitive operations caused by soft tissue obstruction.

[0030] Rapid Instrument Alignment: In existing techniques, the endoscope and operating instruments often fail to align, resulting in low operational efficiency. The design of this dilator allows the UBE endoscope and ablation electrode to align immediately, avoiding issues such as target miss and the endoscope failing to locate the operating instruments. This reduces the learning curve of the technique and shortens the operation time.

[0031] Significant cost-effectiveness: By slightly modifying the original instruments and optimizing the slotted structure to upgrade the function, there is no need to add complex components or expensive materials. While maintaining the compatibility of the original instruments, the surgical results are significantly improved, and the investment cost is low.

[0032] Improved channel fit: The slotted design allows the primary guide rod 1 to form an "embedded" fit with the expansion sleeve. The slotted opening of the expansion tube in the operating channel is precisely aligned with the guide rod in the observation channel, forming a stable mechanical connection. This ensures the stability of the channel during operation and reduces the operational risks caused by instrument shaking or displacement.
