Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an adjustment structure for a spinal surgery access system and a spinal surgery access system having the adjustment structure. Background Technology

[0002] Minimally invasive surgery requires making an incision in the body and expanding the soft tissue at the incision site. After expansion, a minimally invasive surgical space must be created to allow surgical instruments (such as endoscopes or fiber optic illumination tubes) to be inserted through the incision to perform the surgery. This method provides effective operating space, ensuring that the surgery can be completed smoothly in a relatively narrow space, thereby minimizing damage to surrounding tissues.

[0003] In related technologies, the endoscope connector includes a mounting base. The endoscope's channel tube (working channel tube) and the endoscope body are all installed and fixed through the mounting base. During use, the mounting base is first fixed on the connector frame, and the channel tube and the endoscope tube of the endoscope body are inserted into the spine. During the operation, the doctor may need to adjust the operating position according to the situation. However, after the endoscope and the spinal minimally invasive surgery channel are installed through the fixing frame, they cannot move within the predetermined plane, which affects the flexibility of the surgical operation and causes inconvenience in the operation. Summary of the Invention

[0004] This invention aims to at least partially address one of the technical problems in related technologies. To this end, embodiments of this invention propose an adjustable structure for a spinal surgery access system. This adjustable structure has the advantages of improving the surgical field of vision and increasing the flexibility and convenience of surgical operations.

[0006] The adjustment structure of the spinal surgery access system according to an embodiment of the present invention includes an endoscope and a working channel tube, and the adjustment structure includes a support component, an adjustment component, and a mating seat.

[0007] The support assembly is used to install the working channel tube. The mating seat can be connected to the endoscope. The mating seat is oscillatingly connected to the support assembly in a first preset direction via the adjustment assembly so as to realize the displacement of the endoscope tube in the first preset direction.

[0008] The adjustable structure of the spinal surgery access system in this embodiment of the invention connects a support component and a mating seat via an adjusting component. The mating seat is swayably connected to the support component via the adjusting component (e.g., the mating seat is swayably connected to the support component in a horizontal direction via the adjusting component) to allow the endoscope tube to be moved along a first preset direction (e.g., the horizontal direction). This allows the endoscope tube to be adjusted to move perpendicular to its extension direction during surgery, thereby changing the relative position of the endoscope tube within the working channel tube and increasing the range of motion of the endoscope tube. Therefore, the surgeon can adjust the endoscope tube to the ideal position according to the patient's actual condition, thus providing a larger surgical space and a better surgical field of view for minimally invasive surgery, enhancing the flexibility of surgical operations.

[0100] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0101] The following is for reference. Figures 1-37 The adjustment structure 100 of the spinal surgery access system according to an embodiment of the present invention is described.

[0102] The spinal surgery access system adjustment structure 100 of this invention includes an endoscope 300 and a working channel tube 200, and the adjustment structure 100 includes a support component 1, an adjustment component 2 and a mating seat 3.

[0103] The support assembly 1 is used to install the working channel tube 200. The mating seat 3 can be connected to the endoscope 300. The mating seat 3 can be oscillatingly connected to the support assembly 1 along a first preset direction (e.g., horizontal direction) by adjusting the assembly 2 so as to realize the displacement of the endoscope tube 302 of the endoscope 300 along the first preset direction.

[0104] The adjustment structure 100 of the spinal surgery access system in this embodiment of the invention connects the support component 1 and the mating seat 3 via the adjustment component 2. The mating seat 3 is swayably connected to the support component 1 via the adjustment component 2 (for example, the mating seat 3 is swayably connected to the support component 1 in a horizontal direction via the adjustment component 2) to achieve displacement of the endoscope tube 302 of the endoscope 300 along a first preset direction. This allows control of the movement of the endoscope tube 302 of the endoscope 300 along a direction perpendicular to the extension of the endoscope tube 302 during surgery, changing the relative position of the endoscope tube 302 and the working channel tube 200, thereby increasing the range of motion of the endoscope tube 302. This allows the surgeon to adjust the endoscope tube 302 to a more ideal position according to the patient's actual situation, thereby obtaining a larger surgical space and a better surgical field of view in minimally invasive spinal surgery, enhancing the flexibility of surgical operation.

[0105] Therefore, the adjustment structure 100 of the spinal surgery access system in this embodiment of the invention has the advantages of improving the surgical field of vision and increasing the flexibility and convenience of surgical operations.

[0106] For example, the adjusting component 2 can be a limiting post that enables the hinge connection between the support component 1 and the mating seat 3.

[0107] like Figure 2 and Figure 7As shown, the mating seat 3 is swayably connected to the support assembly 1 via the adjusting component 2 along a second preset direction to realize that the endoscope tube 302 of the endoscope 300 is swaying along the second preset direction (e.g., Figure 2 The displacement (shown in the up-down direction) is perpendicular to the first preset direction and the second preset direction. It can be understood that the endoscope tube 302 can move along multiple dimensions (the first preset direction and the second preset direction). For example, Figure 2 As shown, the endoscope tube 302 can be adjusted horizontally and vertically according to the patient's surgical position via the adjustment structure 100.

[0108] The adjustment structure 100 of the spinal surgery access system in this embodiment of the invention can more comprehensively adjust the position of the endoscope tube 302 by shifting the endoscope tube 302 of the endoscope 300 along the first preset direction and the second preset direction, thereby further improving the operating space and surgical field of minimally invasive surgery.

[0109] like Figures 7 to 10 As shown, the adjustment assembly 2 includes an adjustment body 21 and a ball-end fitting 22. One of the adjustment body 21 and the ball-end fitting 22 is connected to the support assembly 1, and the other of the adjustment body 21 and the ball-end fitting 22 is connected to the fitting seat 3. One end of the ball-end fitting 22 is disposed within the adjustment body 21 and is rotatable within the adjustment body 21. In other words, the adjustment body 21 is connected to the support assembly 1, and the ball-end fitting 22 is connected to the fitting seat 3; or the ball-end fitting 22 is connected to the support assembly 1, and the adjustment body 21 is connected to the fitting seat 3.

[0110] The adjustment structure 100 of the spinal surgery access system in this embodiment of the invention achieves the connection and position adjustment between the support component 1 and the mating seat 3 by adjusting the main body 21 and the ball head mating component 22, thereby simultaneously realizing the displacement of the mating seat 3 in a first preset direction and a second preset direction. Therefore, the adjustment structure 100 has the advantage of high ease of adjustment.

[0111] Furthermore, by adjusting the interaction between the main body 21 and the ball-head fitting 22, a rotational engagement between the support assembly 1 and the fitting seat 3 can be achieved, thereby adjusting the relative position and tilt direction of the support assembly 1 within the working channel tube 200. This allows for more comprehensive adjustment of the position and orientation of the endoscope tube 302. Consequently, the operating space and surgical field of view for minimally invasive surgery are further enhanced.

[0112] Specifically, such as Figure 8 As shown, the adjusting body 21 is provided with a ball socket 211, one end of the ball head fitting 22 is disposed in the ball socket 211, and the end of the ball head fitting 22 with the ball head can rotate in the ball socket 211.

[0113] like Figure 8 and Figure 10As shown, the adjusting body 21 includes a sleeve 212, one end of which is connected to the support assembly 1. The ball head fitting 22 includes a connected ball head 221 and a connecting part 222. The connecting part 222 is connected to the fitting seat 3. The ball head 221 is disposed inside the sleeve 212 and can rotate omnidirectionally inside the sleeve 212.

[0114] The adjustment structure 100 of the spinal surgery access system in this embodiment of the invention is rotatably mounted inside a sleeve 212 via a ball head 221, and the sleeve 212 provides a certain limiting fit to the ball head 221. Therefore, the adjustment structure 100 provides structural stability.

[0115] like Figure 8 and Figure 10 As shown, the adjusting assembly 2 also includes a ball head locking member 24, which is radially inserted into the sleeve 212 on the portion of the sleeve 212 near the ball head 221, and the ball head locking member 24 can abut against the ball head 221 to restrict the rotation of the ball head 221.

[0116] The adjustment structure 100 of the spinal surgery access system in this embodiment of the invention can abut against the ball head 221 through the ball head locking member 24 to limit the ball head 221. This allows for pre-operative adjustment of the angle between the connecting part 222 and the adjusting body 21, ensuring the endoscope tube 302 is adjusted to a suitable height and angle. The ball head 221 is then fixed by the ball head locking member 24 to prevent instability and wobbling during surgery due to an unstable connection between the support component 1 and the mating seat 3. This improves the stability of the connection between the support component 1 and the mating seat 3 during surgery.

[0117] like Figure 8 and Figure 10 As shown, the sleeve 212 has a tapered ball head locking hole 214 through which the ball head locking member 24 passes. The ball head locking member 24 is provided with a tapered portion 241, which fits into the ball head locking hole 214, and the ball head 221 can abut against the side of the tapered portion 241.

[0118] The adjustment structure 100 of the spinal surgery access system in this embodiment of the invention, such as... Figure 37 As shown, by providing a tapered portion 241 on the ball head locking member 24, the ball head 221, which has already been adjusted, is positioned during the process of changing the position of the ball head locking member 24 in the ball head locking hole 214. This further improves the stability of the connection between the support assembly 1 and the mating seat 3 during surgery.

[0119] like Figure 8 and Figure 10As shown, the adjustment assembly also includes a main body 213, which is disposed inside the sleeve 212 and has a ball socket 211 at one end, which rotates with the ball head 221.

[0120] The adjustment structure 100 of the spinal surgery access system in this embodiment of the invention has a ball socket 211 on the main body 213. The ball socket 211 rotates and engages with the ball head 221, and the ball socket 211 covers and limits the ball head 221. This improves the stability of the connection between the support component 1 and the mating seat 3 during surgery.

[0121] like Figure 8 and Figure 10 As shown, the adjusting body 21 also includes a main body limiting member 23. The main body limiting member 23 passes through the sleeve 212 radially and can abut against the main body part 213. The main body part 213 slides with the main body limiting member 23 along the axial direction of the sleeve 212. Specifically, the main body part 213 is movably disposed inside the sleeve 212. The main body limiting member 23 can prevent the main body limiting member 23 from rotating circumferentially along the sleeve 212, while the main body part 213 can move axially along the sleeve 212, thereby ensuring the effect of universal rotation between the main body part 213 and the ball head 221.

[0122] The adjustment structure 100 of the spinal surgery access system in this embodiment of the invention uses a main body limiting member 23 to rotate and limit the main body 213, and to move the main body 213 along the axial direction of the sleeve 212. By changing the position of the main body 213 in the sleeve 212, the ball head 221 can be further positioned. This further improves the stability of the connection between the support component 1 and the mating seat 3 during surgery.

[0123] Furthermore, compared to the welding connection between the sleeve 212 and the main body 213, the adjustment structure 100 of the spinal surgery channel system of this embodiment has a main body limiting member 23 as a pin, which can be interference-fitted or threaded onto the sleeve 212. The sleeve 212 and the main body 213 are fixed by the main body limiting member 23, which has the advantages of simple structure and convenient assembly and disassembly.

[0124] Specifically, the sleeve 212 is provided with a limiting opening 2121, the connecting part 222 passes through the limiting opening 2121, and the part of the connecting part 222 located outside the ball socket 211 can swing at the limiting opening 2121.

[0125] Optionally, such as Figure 8As shown, the connecting part 222 is detachably connected to the mating seat 3. Therefore, when transporting or storing the endoscope channel system 1000 having the adjustment structure 100, one end of the connecting part 222 can be detached from the mating seat 3. This has the advantages of saving storage space occupied by the endoscope channel system 1000 and improving transportation efficiency.

[0126] For example, such as Figure 4 As shown, the mating seat 3 may be provided with a threaded hole, and the outer peripheral wall of the connecting part 222 has an external thread, and the connecting part 222 is threadedly engaged with the mating seat 3. The mating seat 3 and the ball head mating part 22 are fixed by a threaded connection, which has the advantages of high ease of assembly and disassembly and good structural stability.

[0127] Furthermore, for example, Figure 2 and Figure 4 As shown, the threaded hole extends at an angle relative to the first preset direction. The threaded hole is inclined downwards towards the front side.

[0128] like Figures 3 to 6 As shown, the mating seat 3 includes a mating seat body 31 and a limiting component 32. The adjusting component 2 is connected to the mating seat body 31. The mating seat body 31 has a mounting cavity 311, and the limiting component 32 is disposed within the mounting cavity 311. The mating seat body 31 can be detachably connected to the endoscope 300 via the limiting component 32. It can be understood that the endoscope 300 is detachably connected to the mating seat body 31 via the limiting component 32.

[0129] The adjustment structure 100 of the spinal surgery access system of this invention, through the cooperation of the mounting body 31 and the limiting component 32, allows the endoscope 300 to be detachably connected to the mounting body 31 via the limiting component 32. When transporting or storing the endoscope access system 1000 equipped with this adjustment structure 100, the endoscope 300 can be detached from the mounting body 31. Therefore, this adjustment structure 100 has the advantages of saving storage space occupied by the endoscope access system 1000 and improving transportation efficiency.

[0130] Specifically, such as Figure 4 and Figure 6 As shown, the mating seat 31 is provided with a mounting hole 312, which extends along the second preset direction. The external rod 303 can be inserted into the mounting hole 312. The external rod 303 can be snapped or threadedly connected to the mating seat 31. The connecting part 222 of the ball head mating part 22 is threadedly connected to the mating seat 31.

[0131] like Figure 5 and Figure 6As shown, the limiting component 32 includes a pressing component and a reset part 323 arranged sequentially along a direction perpendicular to the first preset direction. The pressing component is movable along the direction perpendicular to the first preset direction. The reset part 323 is disposed in the mounting cavity 311 to press the pressing component in a direction that extends out of the mounting cavity 311. The pressing component can disengage from and engage with the endoscope 300. In other words, when the pressing component is subjected to external pressure, the pressing component can disengage from the endoscope 300; when the pressure of the pressing component is released, the pressing component can engage with the endoscope 300.

[0132] The adjustment structure 100 of the spinal surgery access system of this invention, through the cooperation of the pressing component of the limiting component 32 and the reset part 323, wherein the reset part 323 is disposed in the mounting cavity 311 to press the pressing component in the direction of extending out of the mounting cavity 311, can force the pressing component to move in the direction of extending out of the mounting cavity 311 after the pressing force is released, thereby achieving engagement of the endoscope 300. Therefore, this adjustment structure 100 has the advantages of simple structure and further improved ease of assembly and disassembly.

[0133] like Figure 5 and Figure 6 As shown, the pressing assembly includes a pressing part 321 and a sliding part 322 connected to each other. The sliding part 322 is movable along a direction perpendicular to a first preset direction and is located between the pressing part 321 and the reset part 323. The reset part 323 can drive the sliding part 322 to move towards the pressing part 321 to engage with the endoscope 300. The pressing part 321 can drive the sliding part 322 to move to disengage from the endoscope 300.

[0134] The adjustment structure 100 of the spinal surgery channel system of this invention divides the limiting component 32 into a pressing part 321 and a sliding part 322. The pressing part 321 can drive the sliding part 322 to move so as to disengage from the endoscope 300 (specifically, the external rod of the endoscope 300), which has the advantage of high ease of operation.

[0135] Optionally, one end of the pressing part 321 (e.g., Figure 5 The right end shown is connected to the sliding part 322, and the other end of the pressing part 321 can (for example, Figure 5 The left end (shown) extends out of the mounting cavity 311 to compress the sliding part 322, thereby disengaging the sliding part 322 from the endoscope 300. The adjustment structure 100 of the spinal surgery access system of this embodiment improves the ease of operation of the pressing part 321 by extending the other end of the pressing part 321 out of the mounting cavity 311. This further enhances the advantage of improving the mounting and dismounting of the endoscope 300.

[0136] Optionally, the sliding part 322 is provided with a receiving hole 3223 at one end near the reset part 323, and one end of the sliding part 322 (for example, Figure 5 The left end shown is disposed within the receiving hole 3223, and the other end of the reset part 323 (for example, Figure 5 The right end of the reset part 323 extends out of the receiving hole 3223, and the other end of the reset part 323 abuts against the wall of the mounting cavity 311. The adjustment structure 100 of the spinal surgery channel system of this embodiment of the invention, by setting the reset part 323 in the receiving hole 3223, has a certain limiting and guiding effect on the stroke of the reset part 323, and has the advantage of improving the structural stability of the limiting component 32.

[0137] Optionally, the reset element 323 can be a compression spring.

[0138] like Figure 5 and Figure 6 As shown, the limiting component 32 also includes a first limiting member 324. The pressing component is provided with a limiting recess 3224. One end of the first limiting member 324 abuts against the limiting recess 3224. The limiting recess 3224 can move relative to the first limiting member 324 along a first preset direction.

[0139] The adjustment structure 100 of the spinal surgery access system in this embodiment of the invention, through the cooperation of the first limiting member 324 and the limiting recess 3224 on the pressing component, can limit the travel range of the pressing component along a direction perpendicular to the first preset direction, thus preventing the force exerted by the pressing component on the reset part 323 from exceeding the travel range of the reset part 323. This has the advantage of extending the service life of the limiting component 32.

[0140] like Figure 5 and Figure 6 As shown, the pressing component has a limiting protrusion 3222, which can engage with the external rod of the endoscope 300. This prevents the endoscope 300 from shaking due to rotation or movement along a second preset direction during use. This improves the stability and reliability of the connection between the external rod 303 and the mating seat 3.

[0141] Specifically, the sliding part 322 includes a connected slider body 3221 and a limiting protrusion 3222. The limiting protrusion 3222 can abut against the external rod 303 of the endoscope 300. The external rod 303 of the endoscope 300 has an external rod interface 304. The limiting protrusion 3222 is engaged with the external rod interface 304. The slider body 3221 can move relative to the first limiting member 324 in a first preset direction. Therefore, during use, the problem of overall shaking of the endoscope 300 caused by the rotation of the external rod 303 and its movement in a second preset direction can be prevented. This further improves the stability and reliability of the connection between the external rod 303 and the mating seat 3.

[0142] Furthermore, the external rod 303 can be a rectangular column, and an external rod interface (slot) 304 is provided on the rectangular column.

[0143] like Figure 1 and Figure 2 As shown, the support assembly 1 includes a support base 11 and a support arm 12. The support base 11 is used to install the working channel tube 200. One end of the support arm 12 is detachably connected to the support base 11, and the other end of the support arm 12 is connected to the adjustment assembly 2.

[0144] The adjustment structure 100 of the spinal surgery access system of this invention is detachably connected to the support base 11 via one end of the support arm 12. When transporting or storing the endoscope access system 1000 equipped with this adjustment structure 100, the support arm 12 can be detached from the support base 11. Therefore, this adjustment structure 100 has the advantages of saving storage space occupied by the endoscope access system 1000 and improving transportation efficiency.

[0145] Optionally, the other end of the support arm 12 can be fixedly connected to the adjustment component 2.

[0146] like Figure 2 As shown, the support arm 12 includes a first rod 121 and a second rod 122 connected together. The first rod 121 has a first end and a second end disposed opposite to each other, and the second rod 122 has a third end and a fourth end disposed opposite to each other. The fourth end is connected to the adjustment assembly 2. The first end of the first rod 121 is rotatably connected to the support base 11, and / or the second end and the third end of the first rod 121 are rotatably connected. In other words, the first end of the first rod 121 is rotatably disposed relative to the support base 11, and the second end and the third end of the first rod 121 are fixedly connected; or, the first end of the first rod 121 is detachably connected to the support base 11, and the second end and the third end of the first rod 121 are rotatably connected; or, the first end is rotatably connected to the support base 11, and the second end and the third end are rotatably connected.

[0147] The adjustment structure 100 of the spinal surgery access system in this embodiment of the invention is rotatably connected to the support seat 11 via the first end of the first rod 121. This allows adjustment of the angle between the first rod 121 and the support seat 11 before or during surgery, thereby further increasing the distance between the support seat 11 and the mating seat 3 along the first and second preset directions. This enables more comprehensive adjustment of the position of the endoscope tube 302, further enhancing the operating space and surgical field of view for minimally invasive surgery.

[0148] The adjustment structure 100 of the spinal surgery access system in this embodiment of the invention is rotatably connected to the second end of the first rod 121 and the third end of the second rod 122, allowing adjustment of the angle between the first rod 121 and the second rod 122, thereby further increasing the distance between the first rod 121 and the second rod 122 along a first preset direction and a second preset direction. This further enhances the positional dimension of the endoscope tube 302, thereby further improving the operating space and surgical field of view for minimally invasive surgery.

[0149] Accordingly, the first end is rotatably connected to the support base 11, and the second end is rotatably connected to the third end. This further enhances the operating space and surgical field of view for minimally invasive surgery. For example, before surgery, medical personnel can adjust the height of the assisted seat 3 and endoscope 300 to a greater extent according to their needs. The first end of the first rod 121 is then fixed to the support base 11, and the second end of the first rod 121 is fixed to the third end of the second rod 122. This avoids the problem of the adjustment structure 100 wobbling during surgery. Therefore, the structural stability of the adjustment structure 100 is further improved.

[0150] like Figure 11 and Figure 24 As shown, a first anti-slip part 1212 is provided at the first end, and a fourth anti-slip part 1122 is provided on the support base 11. The first anti-slip part 1212 can abut against the fourth anti-slip part 1122 to lock the first rod 121 and the support base 11.

[0151] The adjustment structure 100 of the spinal surgery access system in this embodiment of the invention, by providing a first anti-slip part 1212 on the first rod 121 and a fourth anti-slip part 1122 on the support base 11, can further prevent the adjustment structure 100 from shaking during surgery. This further improves the structural stability of the adjustment structure 100.

[0152] Optionally, the first end of the first rod 121 may have a first mating hole 1211, and a first anti-slip part 1212 is disposed near the first mating hole 1211. Correspondingly, the support base 11 is also provided with a fourth mating hole 1121, and a fourth anti-slip part 1122 is disposed near the fourth mating hole 1121, with the first anti-slip part 1212 abutting against the fourth anti-slip part 1122. The first rod 121 and the support base 11 can be fixed by a pin passing through the first mating hole 1211 and the fourth mating hole 1121. In other embodiments, the first rod 121 and the support base 11 can also be fixed by a structure such as a pin or bolt.

[0153] Specifically, the first anti-slip part 1212 can be an anti-slip texture or an anti-slip groove, for example, Figure 11As shown, the first anti-slip part 1212 consists of a plurality of first anti-slip grooves spaced apart circumferentially along the first mating hole 1211.

[0154] like Figure 9 and Figure 11 As shown, a second anti-slip part 1214 is provided at the second end, and a third anti-slip part 1222 is provided at the third end. The second anti-slip part 1214 can abut against the third anti-slip part 1222 to lock the first rod 121 and the second rod 122.

[0155] The adjustment structure 100 of the spinal surgery access system of this embodiment of the invention, by providing a second anti-slip part 1214 on the first rod 121 and a third anti-slip part 1222 on the second rod 122, can further avoid the problem of shaking of the adjustment structure 100 during surgery. This further enhances the structural stability of the adjustment structure 100.

[0156] Optionally, the second end of the first rod 121 has a second mating hole 1213, and a second anti-slip part 1214 is disposed near the second mating hole 1213. The third end of the second rod 122 has a third mating hole 1221, and a third anti-slip part 1222 is disposed near the third mating hole 1221, with the second anti-slip part 1214 abutting against the third anti-slip part 1222. The first rod 121 and the second rod 122 can be fixed by a pin or bolt passing through the second mating hole 1213 and the third mating hole 1221. This provides the advantage of a simple structure.

[0157] like Figure 1 , Figures 13 to 28 As shown, the support assembly 1 also includes a channel ring 13, which is used to install the working channel tube 200. The channel ring 13 has a mounting position 131 along its circumference, and the support base 11 is detachably mounted on the mounting position 131.

[0158] The adjustment structure 100 of the spinal surgery access system of this invention detachably mounts the support base 11 on the mounting position 131, so that one end of the connecting part 222 can be detached from the mating base 3 when transporting or storing the endoscope access system 1000 having the adjustment structure 100. This has the advantage of further saving storage space occupied by the endoscope access system 1000 and improving transportation efficiency.

[0159] like Figure 1 and Figure 13 As shown, there are multiple mounting positions 131, which are spaced apart circumferentially along the channel ring 13, and the support base 11 can be switched on different mounting positions 131.

[0160] The adjustable structure 100 of the spinal surgery access system in this embodiment of the invention features multiple mounting positions 131 spaced apart circumferentially along the access ring 13, with the support base 11 switchably mounted on different mounting positions 131. For example, before surgery, medical personnel can significantly adjust the horizontal height of the support base 3 and endoscope 300 to a suitable position according to their required working range within the horizontal space. This further enhances the operating space and surgical field of view for minimally invasive surgery.

[0161] like Figure 13 and Figure 25 As shown, the support base 11 includes a fixing part 112, a supporting part 111 and a limiting part 113. The fixing part 112 and the limiting part 113 are respectively connected to both sides of the supporting part 111 in the thickness direction (second preset direction). The fixing part 112 is rotatably connected to the supporting arm 12, and the limiting part 113 is detachably disposed on the mounting position 131.

[0162] The adjustment structure 100 of the spinal surgery channel system of this invention is connected to the support arm 12 through the fixing part 112 of the support seat 11, and is fixed and connected to the channel ring 13 through the limiting part 113, which has the advantage of simple structure.

[0163] Specifically, the support part 111 has a first surface and a second surface that are arranged opposite to each other along a second preset direction, the fixing part 112 is connected to the first surface, the fixing part 112 is rotatably connected to one end of the support arm 12, and the limiting part 113 is disposed on the second surface and is detachably disposed on the mounting position 131.

[0164] Optionally, the side of the support 111 closest to the inner wall of the channel ring 13 is arc-shaped, so as to ensure that when the support 11 is placed on the channel ring 13, it will not obstruct the channel ring 13, thereby improving the surgical effect.

[0165] Specifically, the fixing part 112 is provided with a fourth mating hole 1121, and the fixing part 112 is rotatably connected to one end of the support arm 12. For example, the fourth mating hole 1121 and the support arm 12 can be fixed by a limiting pin or bolt.

[0166] like Figure 13 and Figure 25 As shown, the support base 11 is provided with one of a first limiting hole 1311 and a first limiting post 1131, and the channel ring 13 is provided with the other of the first limiting hole 1311 and the first limiting post 1131. The first limiting post 1131 is disposed within the first limiting hole 1311. In other words, the support base 11 is provided with a first limiting hole 1311, and the channel ring 13 is provided with a first limiting post 1131. Or, as... Figure 13 and Figure 25As shown, the support base 11 has a first limiting post 1131, and the channel ring 13 has a first limiting hole 1311.

[0167] The adjustment structure 100 of the spinal surgery channel system of this invention, the support seat 11 and the channel ring 13 cooperate with each other through the first limiting hole 1311 and the first limiting post 1131, so that the support seat 11 and the channel ring 13 can be quickly positioned and installed.

[0168] Optionally, such as Figure 25 As shown, the first limiting post 1131 can be an elliptical post, a rectangular post, or a quincunx-shaped post. Therefore, it prevents the first limiting post 1131 from rotating along the axial direction of the first limiting hole 1311. Consequently, this adjusting structure 100 has the advantage of improving the stability of the connection between the support base 11 and the channel ring 13.

[0169] The support base 11 is provided with one of a second limiting hole 1312 and a second limiting post 1132, and the channel ring 13 is provided with the other of a second limiting hole 1312 and a second limiting post 1132. The second limiting post 1132 is disposed within the second limiting hole 1312. In other words, the support base 11 is provided with a second limiting hole 1312, and the channel ring 13 is provided with a second limiting post 1132. Or, as... Figure 13 and Figure 25 As shown, the support base 11 is provided with a second limiting post 1132, and the channel ring 13 is provided with a second limiting hole 1312.

[0170] In the spinal surgery access system of this embodiment, the adjustment structure 100, the support base 11 and the access ring 13 cooperate with each other through the second limiting hole 1312 and the second limiting post 1132, to further realize the rapid positioning and installation of the support base 11 and the access ring 13.

[0171] like Figure 28 As shown, the support assembly 1 also includes a second limiting member 14, which is detachably mounted on the support base 11 and the channel ring 13 and can lock the support base 11 onto the channel ring 13.

[0172] The adjustment structure 100 of the spinal surgery channel system of this invention can further improve the stability of the connection between the support seat 11 and the channel ring 13 by means of a second limiting member 14 that is detachably inserted through the support seat 11 and the channel ring 13.

[0173] Optionally, the second limiting member 14 includes a driving part 141 and a mating part 142. The mating part 142 passes through a through hole in the support base 11 and is threadedly engaged with the channel ring 13. One end of the driving part 141 is connected to the mating part 142, and the other end of the driving part 141 can extend out of the support base 11. The adjustment structure 100 of the spinal surgery channel system of this embodiment of the invention, through the threaded engagement of the second limiting member 14 with the channel ring 13, can prevent the support base 11 and the channel ring 13 from shifting along a second preset direction. Therefore, it has the advantage of further improving the stability of the connection between the support base 11 and the channel ring 13.

[0174] Furthermore, the second limiting member 14 extends along a second preset direction. An outer peripheral driving groove 1411 (e.g., the outer peripheral driving groove 1411 can be in the form of a "square", "triangular", "double flat", "single flat", or "Hudson") is provided on the outer peripheral wall of the other end of the driving part 141, and an end driving groove 1412 (e.g., a slotted groove, a cross groove, or a quincunx groove) is provided on the other end of the driving part 141. This improves the ease of operation of the corresponding second limiting member 14, so as to meet different needs for manual locking and locking with tools.

[0175] Optionally, the second limiting member 14 further includes a chamfered portion 143, which is connected to the end of the mating portion 142 away from the driving portion 141. This provides a guiding function and improves the ease of assembly and disassembly of the second limiting member 14.

[0176] Furthermore, the support base 11 and the channel ring 13 are further prevented from easily rotating in the circumferential direction by means of the mutual cooperation of the first limiting hole 1311 and the first limiting post 1131, the mutual cooperation of the second limiting hole 1312 and the second limiting post 1132, and the mutual cooperation of the second limiting member 14. This provides the advantage of further improving the stability of the connection between the support base 11 and the channel ring 13.

[0177] Furthermore, the first limiting post 1131, the second limiting post 1132, and the second limiting member 14 are arranged in a triangular pattern. This further enhances the stability of the connection between the support base 11 and the channel ring 13.

[0178] like Figure 15 and Figure 17 As shown, the channel ring 13 includes a first arc-shaped member 132 and a second arc-shaped member 133. One end of the first arc-shaped member 132 is hinged to one end of the second arc-shaped member 133, and the other end of the first arc-shaped member 132 is detachably connected to the other end of the second arc-shaped member 133. The mounting position 131 is disposed on at least one of the first arc-shaped member 132 and the second arc-shaped member 133.

[0179] The adjustment structure 100 of the spinal surgery access system in this embodiment of the invention divides the access ring 13 into a first arc-shaped member 132 and a second arc-shaped member 133, with one end of the first arc-shaped member 132 hinged to one end of the second arc-shaped member 133, and the other end of the first arc-shaped member 132 detachably connected to the other end of the second arc-shaped member 133. This improves the ease of assembly between the working access tube 200 and the access ring 13. Specifically, when the other end of the first arc-shaped member 132 is detached from the other end of the second arc-shaped member 133, the working access tube 200 can be installed within the annular structure formed by the first arc-shaped member 132 and the second arc-shaped member 133. Then, by connecting the other end of the first arc-shaped member 132 to the other end of the second arc-shaped member 133, the working access tube 200 can be fixed within the annular structure.

[0180] Furthermore, such as Figure 13 and Figure 15 As shown, a first through hole is provided at one end of the first arc-shaped member 132, and a second through hole is provided at one end of the second arc-shaped member 133. The first and second through holes are provided with an opening and closing central shaft. One end of the first arc-shaped member 132 and one end of the second arc-shaped member 133 are hinged together by the opening and closing central shaft.

[0181] Optionally, such as Figure 15 As shown, each of the first arc-shaped component 132 and the second arc-shaped component 133 is a semi-circular arc.

[0182] like Figures 13-17 As shown, the channel ring 13 also includes a first connector 134 and a second connector 135. The first connector 134 is connected to the first arc-shaped member 132, and the second connector 135 is connected to the second arc-shaped member 133. The first connector 134 and the second connector 135 are connected by a connecting assembly to close the first arc-shaped member 132 and the second arc-shaped member 133.

[0183] The adjustment structure 100 of the spinal surgery channel system of this invention achieves the connection between the first arcuate member 132 and the second arcuate member 133 of the channel ring 13 through a snap-fit ​​connection between the first connector 134 connected to the first arcuate member 132 and the second connector 135 connected to the second arcuate member 133. This provides advantages such as good structural stability and ease of disassembly of the working channel tube 200.

[0184] like Figure 15 and Figure 17As shown, the connecting assembly includes a positioning member 15 and a fastener 16. One of the positioning member 15 and the fastener 16 is disposed on a first connecting member 134, and the other of the positioning member 15 and the fastener 16 is disposed on a second connecting member 135. The fastener 16 is detachably engaged within the positioning member 15. In other words, the first connecting member 134 is connected to the positioning member 15, and the second connecting member 135 is connected to the fastener 16. Alternatively, the first connecting member 134 is connected to the fastener 16, and the second connecting member 135 is connected to the positioning member 15.

[0185] The connector for a spinal endoscope in this embodiment of the invention improves the stability and convenience of engagement between the first connector 134 and the second connector 135 through the cooperation of the positioning member 15 and the fastener 16.

[0186] like Figures 15 to 23 As shown, the positioning member 15 includes a locking hole 151 and a positioning component 152 disposed inside the locking hole 151. The fastener 16 has a buckle portion 161, which can be inserted into the locking hole 151 and the positioning component 152 can lock the buckle portion 161 into the locking hole 151.

[0187] The connector for a spinal endoscope in this embodiment of the invention is connected to the positioning component 152 of the positioning member 15 via the buckle portion 161 of the fastener 16, which has the advantage of further improving the stability and convenience of the engagement of the first connector 134 and the second connector 135.

[0188] like Figures 15 to 23 As shown, the first connecting member 134 is connected to the positioning member 15. The positioning assembly 152 includes a pressing arm 1521, a locking platform 1522, and an elastic member 1523. One end of the pressing arm 1521 is inserted into the latch hole 151 in a direction perpendicular to the buckle portion 161, and the other end of the pressing arm 1521 extends out of the latch hole 151. One end of the pressing arm 1521 is connected to the locking platform 1522. One end of the elastic member 1523 abuts against the other end of the pressing arm 1521, and the other end of the elastic member 1523 abuts against the first connecting member 134 to press the pressing arm 1521 in the direction in which the pressing arm 1521 extends out of the latch hole 151. The locking platform 1522 can be engaged in the buckle portion 161. The pressing arm 1521 is used to drive the locking platform 1522 to disengage the locking platform 1522 from the buckle portion 161.

[0189] The connector for a spinal endoscope in this embodiment of the invention achieves locking and unlocking of the buckle 161 through the cooperation of the pressing arm 1521, the locking platform 1522, and the elastic member 1523. The elastic member 1523 allows the buckle 161 to automatically engage with the locking platform 1522 when the pressing force on the pressing arm 1521 is released, thus engaging the fastener 16 with the positioning member 15. When the pressing part 321 is pressed, it compresses the elastic member 1523, driving the buckle 161 to disengage from the locking platform 1522. Therefore, it offers the advantage of high ease of operation.

[0190] Optionally, the pressing arm 1521 has a receiving hole 155 along its thickness direction, and the elastic element 1523 is disposed within the receiving hole 155. The depth of the receiving hole 155 is less than the outer diameter of the elastic element 1523, and the width of the receiving hole 155 is greater than the outer diameter of the elastic element 1523. For example, the depth direction of the receiving hole 155 is... Figure 23 In the left-right direction shown, the width of the receiving hole 155 is Figure 23 As shown in the front-back direction, the elastic element 1523 extends in the up-down direction as shown in the figure.

[0191] Optionally, the buckle portion 161 has one of a groove 162 and a protrusion, and the locking platform 1522 has the other of a groove 162 and a protrusion, with the protrusion positioned within the groove 162. In this embodiment of the invention, the connector 3 for a spinal endoscope, through the mutual cooperation of the buckle portion 161 and the locking platform 1522 via the groove 162 and the protrusion, can prevent the buckle portion 161 from disengaging from the locking platform 1522 after the force applied to the pressing arm 1521 is released. This further enhances the stability of the lock between the fastener 16 and the positioning member 15.

[0192] Optionally, Figure 16 and Figure 23 As shown, the positioning component 15 also includes a third limiting component 153. A limiting groove 154 is provided on the side wall of the end of the pressing arm 1521 near the locking table 1522. The third limiting component 153 is arranged along the extension direction perpendicular to the pressing arm 1521, and one end of the third limiting component 153 abuts against the limiting groove 154. In this embodiment of the invention, the connecting seat for a spinal endoscope, through the cooperation between the third limiting component 153 and the limiting groove 154 on the pressing arm 1521, can prevent the positioning component 152 from dislodging from the locking hole 151.

[0193] The following is for reference. Figures 1-36 The spinal surgery access system 1000 described in this embodiment of the invention includes a working access tube 200, an endoscope 300, and an adjustment structure 100 as described above;

[0194] The working channel tube 200 is connected to the support assembly 1, and the endoscope 300 is mounted on the adjustment structure 100. The endoscope 300 and the support assembly 1 are connected through the adjustment structure 100 so that the endoscope tube 302 of the endoscope 300 can be controlled to move along the first preset direction through the adjustment structure 100.

[0195] Therefore, the spinal surgery access system 1000 of this invention has the advantages of improving the surgical field of vision and increasing the flexibility and convenience of surgical operations.

[0196] like Figure 31 and Figure 32 As shown, the working channel tube 200 includes a working cylinder 201. The working cylinder 201 has a first end face 202 and a second end face 203 that are disposed opposite to each other along the axial direction of the channel ring 13. The first end face 202 is connected to the channel ring 13. The cross-sectional area of ​​the working cylinder 201 decreases from the first end face 202 toward the second end face 203 along the extension direction of the working cylinder 201.

[0197] The spinal surgery access system 1000 of this embodiment of the invention reduces the cross-sectional area of ​​the working channel tube 200 along the extending direction of the working cylinder 201 from the first end face 202 toward the second end face 203. This facilitates insertion of the working channel tube 200 into the corresponding incision position of the spine, improving the convenience of implanting the working channel tube 200 into the spine.

[0198] Optionally, such as Figure 32 As shown, the second end face 203 is inclined relative to the extending direction of the working cylinder 201. This facilitates close contact between the end face of the second end 203 and the vertebral plate.

[0199] Furthermore, the angle between the second end face 203 and the extending direction of the working cylinder 201 is 75° to 85°. For example, the angle between the second end face 203 and the extending direction of the working cylinder 201 is 75°, 78°, 81°, 83°, 85°, 87° and 89°.

[0200] Furthermore, the working channel tube 200 is generally conical or elliptical conical.

[0201] Optionally, the diameter of the first end face 202 is 18mm-20mm; the diameter of the second end face 203 is 16mm-18mm. For example, when the working channel tube 200 is generally elliptical-conical, the minor diameter of the first end face 202 is 18mm; the major diameter of the first end face 202 is 20mm. The minor diameter of the second end face 203 is 16mm; the major diameter of the first end face 202 is 18mm. When the working channel tube 200 is generally conical, the diameter of the first end face 202 is 18mm; the diameter of the second end face 203 is 16mm.

[0202] Optionally, the thickness of the working cylinder 201 is 0.6mm-1.5mm. This ensures the structural strength of the working cylinder 201 while preventing it from becoming too thick and encroaching on the inner diameter of the working channel tube 200, thus maximizing the space available for surgical operations. For example, the thickness of the working cylinder 201 can be 0.6mm, 0.8mm, 0.9mm, 1.0mm, 1.2mm, 1.3mm, 1.4mm, and 1.5mm.

[0203] Optionally, the length of the working cylinder 201 is 35mm-60mm. The length of the working cylinder 201 can be selected according to the clinical needs of different patients and doctors.

[0204] like Figure 31 As shown, the first end face 202 of the working cylinder 201 is provided with one of a limiting flange 204 and a fixing groove 137, and the inner peripheral wall of the channel ring 13 is provided with the other of the limiting flange 204 and the fixing groove 137, with the limiting flange 204 disposed within the fixing groove 137. In other words, the first end face 202 of the working cylinder 201 is provided with a limiting flange 204, and the inner peripheral wall of the channel ring 13 is provided with a fixing groove 137; or the first end face 202 of the working cylinder 201 is provided with a fixing groove 137, and the inner peripheral wall of the channel ring 13 is provided with a limiting flange 204.

[0205] The spinal surgery channel system 1000 of this embodiment of the invention further enhances the stability of the connection between the working cylinder 201 and the channel ring 13 through the mutual cooperation between the fixing groove 137 and the limiting protrusion 204.

[0206] like Figure 33 and Figure 34 As shown, the endoscope 300 includes an endoscope body 301 (wherein, the endoscope body 301 can be externally connected to a light source, a water inlet pipe, and a water outlet pipe), an endoscope tube 302, and an external rod 303; one end of the endoscope tube 302 is connected to the endoscope body 301, the endoscope tube 302 extends along a second preset direction, the other end of the endoscope tube 302 extends into the working channel tube 200, and the endoscope tube 302 is circumferentially movable along the inner wall of the working channel tube 200; the external rod 303 is connected to the adjustment structure 100.

[0207] The spinal surgery access system 1000 of this embodiment of the invention features an endoscope tube 302 that is circumferentially movable along the inner wall of the working access tube 200. The endoscope tube 302 fits snugly against the inner wall of the working access tube 200, improving its stability and preventing wobbling during surgery. Furthermore, it increases the internal movement space of the working access tube 200, reducing interference between the endoscope tube 302 and surgical instruments.

[0208] Optionally, the external rod 303 is provided with an external rod interface 304, and the limiting protrusion 3222 of the sliding part 322 abuts against the external rod interface 304. In this embodiment of the spinal endoscope, by providing an external rod interface 304 on the external rod 303, the corresponding cooperation between the limiting protrusion 3222 and the external rod interface 304 prevents the external rod 303 from rotating and further prevents it from moving in the second preset direction. This further enhances the stability of the connection between the external rod 303 and the mating seat 3.

[0209] like Figure 2 , Figure 35 and Figure 36 The spinal surgery access system 1000 shown also includes a connecting arm 400.

[0210] The channel ring 13 is connected to the connecting arm 400, which includes a main rod 401 and a limiting platform 404 disposed on the main rod 401. The support assembly 1 has a connecting arm interface 136, which is disposed on the limiting platform 404 so as to be detachably connected to the connecting arm 400.

[0211] The spinal surgery channel system 1000 of this embodiment of the invention uses a channel ring 13 connected to a connecting arm 400 to fix the position of the channel ring 13, thereby improving the stability of the position of the channel ring 13 and preventing the channel ring 13, the working channel tube 200 connected to the channel ring 13, and the support seat 11 from shaking during the operation.

[0212] Optionally, such as Figure 35 As shown, the spinal surgery access system 1000 of this embodiment of the invention further includes a locking nut 403, which is disposed on the main rod 401 in a direction perpendicular to the axial direction of the main rod 401, forming a limiting platform 404 between the locking nut 403 and the main rod 401. The spinal endoscope of this embodiment, by providing the locking nut 403 and the limiting platform 404 formed on the main rod 401, improves the ease of installation and disassembly of the access ring 13 and the connecting arm 400.

[0213] Specifically, the end of the second connector 135 away from the channel ring 13 is provided with a connecting arm interface 136 for detachable connection with the connecting arm 400. The locking nut 403 engages with the threaded structure of the main rod 401 so that when the locking nut 403 is close to the main rod 401, it can press the second connector 135 to achieve the connection and fixation between the adjusting structure 100 and the connecting arm 400.

[0214] like Figure 15As shown, the connecting arm interface 136 can be U-shaped. When fixing the connecting arm 400 and the second connecting member 135, the connecting arm interface 136 is inserted into the part of the locking nut 403 with the locking stud. Before fixing, the included angle between the second connecting member 135 and the main rod 401 can be rotated to adjust the position of the connecting arm 400, the working channel tube 200, and the endoscope body 301 relative to the connecting arm 400, facilitating operation by medical personnel.

[0215] Furthermore, the connecting arm 400 also includes a reinforcing tool rod 402 connected to the main rod 401 and a reinforcing tool interface 405 disposed on the reinforcing tool rod 402. The reinforcing tool interface 405 can be externally connected to other handles or tools to improve the structural stability of the connecting arm 400. The reinforcing tool interface 405 can be a square, triangular, double-flat, single-flat, or Hudson type interface.

[0216] The outer peripheral wall of the locking nut 403 can also be provided with a corresponding external drive groove; alternatively, a corresponding tool drive groove can be provided on the head of the locking nut 403. The specific configuration can be tailored to different needs, such as manual locking or tool-assisted locking. This improves the ease of disassembly or rotation of the locking nut 403.
