[0002] With the development of medical technology, surgical robots are being used more and more widely. At the same time, the application of visual trephineing technology is also becoming increasingly widespread. Visual trephineing technology involves removing bone tissue using a trephine under endoscopic guidance, and it is commonly used in minimally invasive spinal surgery.

[0003] In minimally invasive spinal surgery, bone tissue can be removed using a trephine saw under endoscopic guidance, effectively avoiding nerve damage caused by lack of visual field during trephine saw operation. However, this trephine saw cannot be used in conjunction with surgical robots in minimally invasive spinal surgery, resulting in manual operation of the trephine saw for bone removal, leading to longer operation times and higher surgical risks.

[0034] To make the objectives, technical solutions, and advantages of this specification clearer, the technical solutions of this specification will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this specification, and not all of them. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this specification.

[0035] Additionally, it should be noted that all actions involving the acquisition of signals, information, or data in this invention are carried out in compliance with the relevant data protection laws and regulations of the country where the invention is located, and with authorization from the owner of the corresponding device.

[0036] Currently, minimally invasive spinal surgery requires surgical tools such as trephine saws to handle bone tissue. However, because the surgical area contains many important nerve tissues, trephine saws can easily damage these nerves. Using a trephine saw to remove bone tissue under endoscopic visualization effectively avoids nerve damage caused by not being able to see the surgical area during trephine saw operation, thus greatly reducing surgical risks. Therefore, the trephine saw, composed of a trephine saw and an endoscope, is a frequently used surgical tool in minimally invasive spinal surgery.

[0037] However, this visual ring saw cannot be used with surgical robots. In other words, the visual ring saw cannot be connected to a surgical robot and used together in minimally invasive spinal surgery. This means that in minimally invasive spinal surgery, the visual ring saw can only be operated manually to perform bone sawing, which results in longer operation time and higher surgical risks.

[0038] Based on this, this specification provides a surgical tool that uses a control structure to rotate a fixation bolt along the axis of a ring saw. This fixation bolt drives the ring saw to rotate, and as the control structure rotates the fixation bolt, the ring saw is pulled along by the bolt, allowing the target tissue in the surgical area to be removed through the saw teeth. Simultaneously, while the ring saw rotates to remove the target tissue, an endoscope provides a surgical field of view of the surgical area. The control structure connects the ring saw and endoscope to a surgical robot, enabling the surgical robot to control the ring saw and endoscope for minimally invasive spinal surgery, saving surgical time and reducing surgical risks.

[0039] The technical solutions provided in the various embodiments of this specification are described in detail below with reference to the accompanying drawings.

[0040] Figure 1 This is a schematic diagram of one of the surgical tools described in this instruction manual.

[0041] The surgical tool provided in this manual can be used in surgical areas where bone tissue needs to be removed. This surgical tool can be used in any existing minimally invasive spinal surgery scenario and can be configured on a surgical robot for automatic control.

[0042] The surgical tools provided in this manual include a trephine saw 1 and an endoscope 2. The trephine saw 1 includes a serrated head 101, a hollow tube body 102, a locking groove 103, and a fixing bolt 104, as detailed below. Figure 2 As shown, Figure 2 This is a schematic diagram of a ring saw provided in this specification. Figure 2The ring saw 1 shown includes a saw head 101, a hollow tube 102, a snap-fit ​​groove 103, and a fixing bolt 104. The snap-fit ​​groove 103 is located on the fixing bolt 104. The working channel established by the hollow tube 102 can accommodate the endoscope 2. The ring saw 1 is snapped into the control structure 3 through the snap-fit ​​groove 103, and the fixing bolt 104 is connected to the control structure 3. The endoscope 2 is deployed inside the hollow tube 102.

[0043] The fixing bolt 104 is used to rotate the ring saw 1 when the control structure 3 rotates the fixing bolt 104 along the axis of the ring saw 1. The ring saw 1 is rotated by the fixing bolt 104 when the control structure 3 rotates, so that the target tissue in the surgical area can be removed through the saw teeth. The endoscope 2 is used to provide a surgical field of view of the surgical area when the ring saw 1 rotates to remove the target tissue. The target tissue can be bone tissue in the surgical area.

[0044] In one or more embodiments of this specification, such as Figure 3 As shown, Figure 3 This is a schematic diagram of an endoscope provided in this specification. The endoscope 2 includes an anti-rotation handle 201. When the endoscope 2 is deployed inside the hollow tube 102, the anti-rotation handle 201 is fixed to the control structure 3. It is used to keep the endoscope 2 stationary when the trephine 1 rotates to remove the target tissue, so as to avoid the field of view shift caused by the endoscope 2 when the trephine 1 rotates to remove the target tissue. This ensures that the endoscope 2 remains stationary when the trephine 1 rotates to remove the target tissue, avoids the rotation of the endoscope 2, ensures the safety of the operation, and also prevents the rotation of the trephine 1 from causing the endoscope 2 to rotate and interfering with the surgical operation.

[0045] In one or more embodiments of this specification, such as Figure 3As shown, the endoscope 2 includes a scope body 202 and several stabilizing rings 203, each stabilizing ring 203 being fitted onto the scope body 202. Each stabilizing ring 203 is used to ensure that the axis of the scope body 202 is aligned with the axis of the hollow tube 102. The number of stabilizing rings 203 can be two or more. In this embodiment, at least two stabilizing rings 203 are typically installed to ensure that the axis of the scope body 202 is aligned with the axis of the hollow tube 102. This prevents visual field shift caused by the endoscope 2 when the ring saw 1 rotates to remove the target tissue, ensuring that the endoscope 2 remains stationary during the removal of the target tissue, preventing endoscope 2 from shaking and ensuring surgical safety. Simultaneously, the stabilizing rings 203 also act as bearings, preventing friction between the scope body 202 and the hollow tube 102, which could cause damage to either. In practical applications, the number of stabilizing rings 203 can be determined according to the specific application scenario; this specification does not limit this. Typically, the number and position of the stabilizing rings 203 determine whether the axis of the endoscope body 202 and the axis of the hollow tube body 102 are the same, and thus determine whether the field of view generated by the endoscope 2 is offset when the ring saw 1 rotates to remove the target tissue. Figure 3 The number of stabilizing rings 203 shown is two, and the two stabilizing rings 203 are respectively fitted onto both ends of the endoscope body 202. This is only an example and does not mean that the surgical tool in this embodiment contains only two stabilizing rings 203. The position of the stabilizing rings 203 is only in the example position. In this embodiment, the number and position of the stabilizing rings 203 can be set in advance according to the usage scenario of the surgical tool, and this specification does not limit this.

[0046] In one or more embodiments of this specification, the inner wall of each stabilizing ring 203 abuts against the outer wall of the endoscope body 202, and the outer wall of each stabilizing ring 203 abuts against the inner wall of the hollow tube 102, so that the axis of the endoscope body 202 and the axis of the hollow tube 102 are the same. This avoids the field of view shift caused by the endoscope 2 when the ring saw 1 rotates to remove the target tissue, ensuring that the endoscope 2 remains stationary when the ring saw 1 rotates to remove the target tissue, thus ensuring surgical safety. At the same time, the stabilizing ring 203 also acts as a bearing to prevent friction between the endoscope body 202 and the hollow tube 102, which could cause damage to either endoscope body 202 or the hollow tube 102.

[0047] In one or more embodiments of this specification, such as Figure 3 As shown, the endoscope 2 includes a water flushing port 204. The water flushing port 204 is connected to the water injection pipe 4, specifically as follows: Figure 4 As shown, Figure 4This is a schematic diagram of an endoscope provided in this specification. The water irrigation port 204 is used to guide the water injected by the water injection tube 4 to the surgical area to irrigate the surgical area, thereby ensuring a clear view of the surgical area. In this specification, the endoscope 2 in the surgical tools includes two water irrigation ports 204. This is only an example and does not mean that the surgical tools in the embodiments of this specification contain only two water irrigation ports 204. In the embodiments of this specification, the number of water irrigation ports 204 can be set in advance according to the usage scenario of the surgical tools, and this specification does not limit this.

[0048] In one or more embodiments of this specification, such as Figure 3 As shown, the endoscope 2 includes a cold light source interface 205. The cold light source interface 205 is used to guide the light emitted from the cold light source to the surgical area to illuminate the surgical area and ensure a clear view of the surgical area. The cold light source can be any existing cold light source, and this specification does not limit its use.

[0049] In one or more embodiments of this specification, such as Figure 3 As shown, the endoscope 2 includes an image transmission interface 206. The image transmission interface 206 is used to transmit images of the surgical area. Typically, a camera is installed at one end of the endoscope 2 near the surgical area. This camera is used to capture images of the surgical area, and the captured images are then transmitted to the surgical robot via the image transmission interface 206. This provides the surgical robot with a view of the surgical area, allowing it to rotate the fixation bolt 104 along the axis of the ring saw 1 using the control structure 3, thereby causing the fixation bolt 104 to rotate the ring saw 1. The ring saw 1 then removes the target tissue from the surgical area using the saw teeth 101.

[0050] In one or more embodiments of this specification, the control structure 3 includes a rotating structure 301. The rotating structure 301 abuts against the fixing bolt 104. The rotating structure 301 is used to drive the fixing bolt 104 to rotate, so that the fixing bolt 104 drives the ring saw 1 to rotate. The rotating structure 301 and the fixing bolt 104 can also be snap-fitted, or they can be plugged in, or connected by threads, hexagonal sockets, etc. This specification does not specifically limit the method of connection between the rotating structure 301 and the fixing bolt 104. This specification only uses the abutting of the rotating structure 301 and the fixing bolt 104 as an example, and does not mean that the rotating structure 301 and the fixing bolt 104 of the surgical tool in the embodiments of this specification are connected only by abutting.

[0051] In one or more embodiments of this specification, the control structure 3 includes a fixing structure 302. The fixing structure 302 is fixed to the control structure 3. The fixing structure 302 is used to fix the anti-rotation handle 201 when the ring saw 1 rotates to remove the target tissue, so as to keep the endoscope 2 stationary and prevent the endoscope 2 from rotating when the ring saw 1 rotates to remove the target tissue, thus avoiding the field of view shift caused by the endoscope 2. This ensures that the endoscope 2 remains stationary when the ring saw 1 rotates to remove the target tissue, ensuring surgical safety.

[0052] In one or more embodiments of this specification, the control structure 3 includes a snap-fit ​​structure 303 located on the control structure 3. The snap-fit ​​structure 303 is used to snap into the snap-fit ​​groove 103 so that when the ring saw 1 rotates to remove the target tissue in the surgical area, the ring saw 1 does not move up and down. At the same time, through the snap-fit ​​structure 303 and the snap-fit ​​groove 103, the surgical robot can drive the fixing bolt 104 to rotate along the axis of the ring saw 1 via the control structure 3, so that the fixing bolt 104 drives the ring saw 1 to rotate, and the ring saw 1 removes the target tissue in the surgical area through the saw teeth 101.

[0053] In one or more embodiments of this specification, such as Figure 5 As shown, Figure 5 This is an exploded view of a surgical tool provided in this specification. Figure 5 The surgical instruments shown include a trephine 1, an endoscope 2, and a control structure 3, all of which are aligned on the same axis, represented by a dashed line passing through them. Figure 5 In the surgical instruments shown, the trephine 1 is the structure within the dashed area, including a serrated head 101, a hollow tube body 102, a locking groove 103, and a fixing bolt 104. The endoscope 2 is the structure within the dashed area, including an anti-rotation handle 201, an endoscope body 202, various stabilizing rings 203, various water flushing interfaces 204, a cold light source interface 205, and an image transmission interface 206. The control structure 3 includes a rotation structure 301, a fixing structure 302, and a locking structure 303.

[0054] In one or more embodiments of this specification, such as Figure 6 As shown, Figure 6 This is an exploded view of a surgical tool provided in this specification. Figure 6 The surgical tools shown include a trephine 1, an endoscope 2, and a control structure 3. The trephine 1 and control structure 3 are connected, and the endoscope 2, along with the structure formed by the connection of the trephine 1 and control structure 3, is on the same axis. Figure 6The surgical instruments shown include a trephine saw 1 with a toothed head 101, a hollow tube 102, a locking groove 103, and a fixing bolt 104; and an endoscope 2 with an anti-rotation handle 201, a scope body 202, various stabilizing rings 203, various water flushing interfaces 204, a cold light source interface 205, and an image transmission interface 206. The control structure 3 includes a rotating structure 301, a fixing structure 302, and a locking structure 303. The rotating structure 301 abuts against the fixing bolt 104, and the locking structure 303 engages with the locking groove 103.

[0055] In one or more embodiments of this specification, the control structure 3 is connected to the surgical robot. The control structure 3 can be connected to the surgical robot via a threaded connection, an internal hexagonal socket, or other similar methods; however, this specification does not impose specific limitations on these methods.
