In the related art, the maximum working channel of the intervertebral foramen endoscope can reach 3.7mm and the outer diameter of the intervertebral foramen endoscope is 6.3mm, and the operation space with the diameter of 6.3mm or more needs to enter a safe triangular area to work, so that the intervertebral foramen needs to be enlarged by using a trepan. However, the existing reaming operation is finished by the sense of doctors, so that the danger of accidentally injuring patients exists, and the operation is very inconvenient because the trepan is pulled out when the reaming effect is required to be observed.

Fig. 1 schematically illustrates a schematic view of an endoscope system provided by an embodiment of the present disclosure. As can be seen in FIG. 1, the endoscopic system includes a trephine assembly 10 and an intra-discal scope 20 located inside the trephine assembly 10. Specifically, the trepan assembly 10 includes a sleeve 100, a metal trepan 101 disposed at a first end of the sleeve 100, and a first handle 102 disposed at a second end of the sleeve 100, at least the first end of the sleeve 100 is a transparent structure, which may be a transparent structure, and a through hole 103 is disposed at a hollow position of the first handle 102 corresponding to the sleeve 100; the transforaminal endoscope 20 comprises an endoscope body 200, an image pickup device 201 arranged at a first end of the endoscope body 200, and an observation eyepiece 202 arranged at a second end of the endoscope body 200, wherein the endoscope body 200 penetrates through the interior of the sleeve 100.

Based on this, when the endoscope system provided by the embodiment of the present disclosure is used, the inter-vertebral foramen mirror 20 can be inserted into the sleeve 100 through the through hole 103 of the trepan assembly 10, and the affected part can be observed through the visual angle of the inter-vertebral foramen mirror 20, and the rotation of the metal trepan 101 can be controlled by the first handle 102 when the reaming operation is needed. Because the first end of the sleeve 100 of the trepan assembly 10 is of a transparent structure, the adjustment of the transforaminal endoscope 20 is facilitated, the transforaminal endoscope 20 is kept in the trepan assembly 10, and the reaming condition can be conveniently observed, so that the operation of the metal trepan 101 is visual, and the convenience and the safety of the operation are guaranteed. For example, referring to FIG. 2, when the foraminoscope 20 is extended, the position of the trephine 101 can be clearly seen; as another example, referring to FIG. 3, when the transforaminal mirror 20 is retracted, the nerve roots may be clearly observed due to the transparent construction of the cannula 100 of the trephine assembly 10.

It should be noted that: the detailed structure of the foraminoscope 20 may include a perfusion channel, a working channel, a light source, a nucleus clamp, and the like in addition to the above-mentioned image capturing device 201 and the observation eyepiece 202, which are not described in detail in this example, and reference may be made to related technologies. In addition, the size of the through-hole 103 in the trepan assembly 10 is increased over the prior art to facilitate placement of the transforaminal lens 20.

In this embodiment, the sleeve 100 and the metal trepan 101 may be fixedly connected by a male-female buckle structure, so that not only the fixed connection between the two can be realized, but also the relative sliding between the two can be effectively prevented. Fig. 4 is a view schematically showing a connection structure of the casing 100 and the metal trepan 101. As shown in fig. 4, the non-sawtoothed end of the metal trepan 101 may be provided with a plurality of annularly distributed protruding structures, the first end of the sleeve 100 may be provided with a plurality of annularly distributed groove structures, and the protruding structures and the groove structures are matched with each other, so that the metal trepan 101 and the sleeve 100 can be relatively fixed. Furthermore, a fixing ring, such as a ring of concave-convex grooves, may be added on the basis of the concave-convex interlocking structure to reinforce the concave-convex interlocking structure. Of course, the fixed connection between the sleeve 100 and the metal trepan 101 is not limited to this, and the sleeve may also be connected by a screw or a plug, and the like, which is not specifically limited in this embodiment.

Here, it should be noted that: the materials for preparing the sleeve 100 and the metal trepan 101 are not limited thereto, as long as the medical requirements can be satisfied.

The trephine assembly 10 in this embodiment comprises a plurality of different bore diameters of the trephine assembly 10, taking into account that different sizes of metal trephines 101 may be used in actual surgical procedures. Because the trephine assembly 10 is in clearance fit with the transforaminal scope 20, the trephine assembly 10 with different apertures is also required to be matched with different transforaminal scopes 20, and the transforaminal scope 20 is generally standard in size, so that the clearance fit with the trephine assembly 10 is realized by arranging the spacer ring 30 outside the transforaminal scope 20.
