Description

Technical Field

[0001] This application relates to the technical field of surgical assistance instruments, and in particular to a UBE / OSE artificial working channel. Background Art

[0002] In the field of spinal surgery, the unilateral biportal endoscopy technology UBE (Unilateral Biportal Endoscopy) / OSE (One-Hole Split Endoscopy) is a minimally invasive spinal surgery technology developed in recent years. This technology is mainly applicable to surgeries for patients with degenerative diseases of the cervical, thoracic, and lumbar vertebrae, such as lumbar discectomy, lumbar laminectomy and decompression, etc.

[0003] However, when initially establishing the observation channel and the working channel during the operation of these two minimally invasive techniques, the surgeon mainly relies on dilating the tube and periosteal elevator to strip the soft tissues such as muscles from the bone surface to establish a surgical operation area. However, after the working area is established, the soft tissues still cannot be effectively isolated. In particular, it is very difficult to effectively connect the observation port and the operation port. During the operation, the operation of soft tissues will invade the field of view, hindering the surgical operation.

[0004] Since this surgery uses a water medium, if the observation channel and the operation channel cannot be effectively connected, the water flow in the channel (flushing the surgical site) will be blocked, resulting in the formation of eddy currents of water in the working area. Eventually, the surgeon's field of view will be blurred. At the same time, there are also drawbacks such as muscle blocking the field of view during the operation and excessive water pressure causing water to penetrate into the surrounding soft tissues, leading to muscle swelling. There is a certain probability that the surgeon will accidentally enter other muscle spaces during the operation, increasing the surgical risk and the operation difficulty. Summary of the Invention

[0005] In order to solve the above problems existing in the existing UBE / OSE technology, this application provides an artificial working channel, which reduces the operation difficulty by establishing an artificial operation channel and an observation channel at the surgical site. At the same time, it expands the operation space by means of active expansion, avoids surgical risks, improves surgical efficiency and safety, reduces the degree of damage to surrounding tissues during the operation, and accelerates the postoperative recovery of patients.

[0006] The above object of this application is achieved through the following technical solutions:

[0007] This application provides a UBE / OSE artificial working channel, including:

[0008] A base;

[0009] An observation channel and an operation channel, both of which are arranged on the first surface of the base, and the observation channel and the operation channel are also communicated with the second surface of the base;

[0010] An expansion cavity, which is provided in the base;

[0011] An inflation port, which is provided on the base and communicates with the expansion cavity;

[0012] Wherein, the base, the observation channel and the operation channel are all made of elastic materials.

[0013] In a possible implementation manner of the present application, a grid structure is provided on at least one inner side surface of the expansion cavity.

[0014] In a possible implementation manner of the present application, the expansion cavity includes a plurality of independent sub-expansion cavities, and adjacent sub-expansion cavities communicate with each other.

[0015] In a possible implementation manner of the present application, an arc-shaped area is provided on the second surface of the base;

[0016] The arc-shaped area or a part of the arc-shaped area is located between the observation channel and the operation channel.

[0017] In a possible implementation manner of the present application, in the direction close to the center of the second surface of the base, the height of the arc-shaped area tends to increase.

[0018] In a possible implementation manner of the present application, an enlarged observation area is provided at the connection between the observation channel and the base, and the coverage area of the enlarged observation area is larger than the coverage area of the inner hole of the observation channel.

[0019] In a possible implementation manner of the present application, an enlarged operation area is provided at the connection between the operation channel and the base, and the coverage area of the enlarged operation area is larger than the coverage area of the inner hole of the observation channel.

[0020] In a possible implementation manner of the present application, the inner hole diameter of the observation channel is 8 mm.

[0021] In a possible implementation manner of the present application, the inner hole diameter of the operation channel is 10 mm.

[0022] In a possible implementation manner of the present application, the distance between the observation channel and the operation channel is 5 - 15 mm.

[0023] The beneficial effects of the present application are as follows:

[0024] The present application provides a UBE / OSE artificial working channel, which reduces the operation difficulty and the observation difficulty by establishing an operation channel and an observation channel at the surgical position. The operation channel is used to supply surgical instruments, and the observation channel can directly observe the position and movement of the surgical instruments, which can effectively shorten the surgical operation time and avoid misoperation.

[0025] At the same time, the operation space is expanded by an active expansion method, which not only further facilitates intraoperative operation and observation, but also avoids the ablation operation on surrounding tissues in the prior art, reduces the damage to surrounding tissues, and accelerates postoperative recovery.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] In order to more clearly understand the technical solutions in the present application, the related technologies will be introduced first.

[0035] The UBE / OSE technology is a minimally invasive technology applied in the field of spinal surgery, which is a minimally invasive surgery technology developed in recent years. The core of the UBE / OSE technology lies in the use of two independent surgical channels, one for the visual display of the endoscope and the other for the operation of surgical instruments. Compared with the traditional spinal endoscope technology, this minimally invasive technology provides a larger surgical field of view and a more flexible operation space, and is especially suitable for complex spinal lesion surgeries, such as lumbar discectomy, lumbar laminectomy and decompression, etc.

[0036] During the current UBE / OSE surgery, there are no suitable tools and instruments to complete the dilation of the surgical operation area. It mainly depends on the surgeon to avoid soft tissues such as muscles according to the surgical needs during the operation by observing the direction and position of the lens, so that the operation field of view is clearly visible. Sometimes when it cannot be avoided, the high-frequency ablation device is used during the operation to excise or vaporize the soft tissues around the working area to achieve a clear view of the working area. However, excising or vaporizing soft tissues will sacrifice some useful muscle tissues, which is not conducive to the rapid recovery of the patient and the minimally invasive concept.

[0037] The technical solutions in this application will be further described in detail below with reference to the accompanying drawings.

[0038] This application discloses an OSE / UBE artificial working channel. In some examples, please refer to Figure 1 and Figure 2 , the OSE / UBE artificial working channel disclosed in this application includes a base 11, an observation channel 12, an operation channel 13, an expansion cavity 14 and an inflation port 15. Here, the posture of the base 11 placed on the horizontal plane is introduced. The surface of the base 11 close to the horizontal plane is the second surface of the base 11, and the surface opposite to the second surface of the base 11 is the first surface of the base 11.

[0039] Both the observation channel 12 and the operation channel 13 are located on the first surface of the base 11 and communicate with the second surface of the base 11. During the operation, the second surface of the base 11 is close to the patient's spine, and the first surface of the base 11 is close to the patient's back skin.

[0040] The expansion cavity 14 is located inside the base 11 and communicates with the inflation port 15 on the base 11. Before being placed in the surgical position, the expansion cavity 14 is in an uninflated state.

[0041] In some possible implementation manners, the inner hole diameter of the observation channel 12 is 8 mm.

[0042] In some possible implementation manners, the inner hole diameter of the operation channel 13 is 10 mm.

[0043] In some possible implementation manners, the distance between the observation channel 12 and the operation channel 13 is 5 - 15 mm.

[0044] The base 11, the observation channel 12 and the operation channel 13 in this application are all made of elastic materials. Before being placed in the surgical position, first fold the base 11, the observation channel 12 and the operation channel 13, for example, by using an extrusion method, and restore the base 11, the observation channel 12 and the operation channel 13 to their original shapes after being placed in the surgical position.

[0045] After being placed at the surgical position, inflation begins through the inflation port 15 into the interior of the inflation cavity 14. At this time, the volume of the inflation cavity 14 increases, and an operating space appears between the second surface of the base 11 and the spine. This operating space can not only provide a larger operating space for the surgeon but also facilitate the surgeon to observe the specific position and movement of surgical instruments through the observation channel 12 and other contents.

[0046] This operating space also has the following advantages:

[0047] It can achieve the effective penetration of the observation port and the operation port, make the water flow smoother, and is conducive to surgical operations;

[0048] It can make the observation channel and the operation channel more smooth when changing instruments during the operation, avoid entering different muscle gaps when reinserting instruments, and increase the surgical risk and time;

[0049] It realizes the effective isolation of the working area from the surrounding soft tissues, making the surgical operation field clearer and safer.

[0050] In some examples, please refer to Figure 3 , a grid structure 16 is provided on at least one inner side surface of the inflation cavity 14. The function of the grid structure 16 is to prevent the inner wall of the inflation cavity 14 from fitting together, resulting in situations where the volume of the inflation cavity 14 cannot increase, the volume increase is insufficient, and the local volume cannot increase during inflation.

[0051] In other examples, please refer to Figure 4 , the inflation cavity 14 includes a plurality of independent sub-inflation cavities 141. The adjacent sub-inflation cavities 141 are connected. The function of the sub-inflation cavities 141 is the same as that of the grid structure 16, and will not be elaborated here.

[0052] In some examples, please refer to Figure 5 and Figure 6 , an arc-shaped area 17 is provided on the second surface of the base 11. The function of the arc-shaped area 17 is to provide a larger operating space, facilitate the operation and observation of surgical instruments at the same time, and the arc-shaped area 17 or a part of the arc-shaped area 17 is located between the observation channel 12 and the operation channel 13.

[0053] Or it can be described as in the direction close to the center position of the second surface of the base 11, the height of the second surface of the base 11 tends to increase.

[0054] In some possible implementation manners, in the direction close to the center of the second surface of the base 11, the height of the arc-shaped area 17 tends to increase.

[0055] In some examples, please refer to Figure 5 and Figure 7An enlarged observation area 121 is provided at the connection between the observation channel 12 and the base 11. The coverage area of the enlarged observation area 121 is larger than the coverage area of the inner hole of the observation channel 12. When the shape of the observation channel 12 is circular, the shape of the enlarged observation area 121 is also circular.

[0056] At the same time, in the direction approaching the second surface of the base 11, the coverage area of the expanded observation area 121 also tends to increase.

[0057] For some examples, see Figure 5 and Figure 7 An enlarged operating area 131 is provided at the connection between the operating channel 13 and the base 11. The coverage area of the enlarged operating area 131 is larger than the coverage area of the inner hole of the operating channel 13. When the shape of the operating channel 13 is circular, the shape of the enlarged operating area 131 is also circular.

[0058] At the same time, in the direction approaching the second surface of the base 11 , the coverage area of the expanded operation area 131 also tends to increase.

[0059] The expanded observation area 121 and the expanded operation area 131 have the same function, which is to further expand the operation space and facilitate the operation and observation of surgical instruments.

[0060] exist Figure 1 It can be seen that the projection of the base 11 can be described as consisting of two sides and two semicircles. The two sides include a straight line and an arc, that is, there is a protruding part on the base 11. The function of this protruding part is to support the soft tissue at the surgical site so that the space under the base 11 can be further increased.

[0061] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
