Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a side-opening spinal working channel. Background Technology

[0002] With the development of precision medicine, the precision and minimally invasive nature of lumbar spine surgery are gaining increasing popularity. Compared to traditional open surgery, minimally invasive lumbar spine surgery utilizes the instrument channel of a lumbar septum to insert surgical instruments and endoscopes, allowing for surgery through smaller incisions. This results in less traction and dissection of soft tissues, thus reducing postoperative pain and shortening recovery time. Dual-channel minimally invasive spinal surgery uses one channel for endoscopy and the other for instruments; these two channels function independently. Procedures such as inserting fusion devices and bone grafting can be performed through the other channel under the monitoring of a camera in one port.

[0003] However, the dual-channel method requires two incisions in the patient, which cannot further reduce incision trauma. In addition, the surgical area, surgical instruments, and surgical procedures can only be monitored through an endoscope, resulting in a limited field of vision. Moreover, the use of a round tube to provide instrument access, coupled with the narrow space within the tube, makes it difficult for the surgeon to maneuver the surgical instruments flexibly. These disadvantages, such as limited field of vision and low maneuverability, increase the difficulty of the surgery. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a side-opening spinal working channel with its own endoscope channel, which only requires one hole to be made in the patient, thus helping to reduce incision trauma; in addition, it also allows doctors to directly see the instrument channel and operate surgical instruments more flexibly.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A side-opening spinal working channel includes a C-shaped tube. An instrument channel and an endoscope channel are formed on the inner side of the C-shaped tube. The endoscope channel is located on the radial side of the instrument channel and is inclined relative to the instrument channel. A side opening of the instrument channel is formed on the side of the C-shaped tube.

[0007] Furthermore, the endoscope channel and the side opening are located on the radial sides of the instrument channel, respectively.

[0008] Furthermore, the endoscope channel is open on the side facing the instrument channel, and there is an anti-rotation limiting channel between the upper part of the endoscope channel and the upper part of the instrument channel. The lower part of the endoscope channel and the lower part of the instrument channel meet together.

[0009] Furthermore, the inner wall of the C-shaped tube includes a first channel inner wall for forming an instrument channel, a second channel inner wall for forming an endoscope channel, and a third channel inner wall for forming an anti-rotation limiting channel. The second channel inner wall is recessed relative to the first channel inner wall, and the third channel inner wall has two sides that are arranged opposite to each other. The anti-rotation limiting channel is formed between the two third channel inner walls.

[0010] Furthermore, the inner wall of the third channel is located between the upper part of the inner wall of the first channel and the upper part of the inner wall of the second channel, and the lower part of the inner wall of the first channel and the lower part of the inner wall of the second channel meet together.

[0011] Furthermore, one side of the outer wall of the C-shaped tube protrudes to form the outer wall of the endoscope channel, and the degree of protrusion of the outer wall of the channel gradually decreases from the top to the bottom of the C-shaped tube.

[0012] Furthermore, the bottom of the C-shaped tube is angled, with the endoscope channel positioned on the side with the lower angle and the side opening positioned on the side with the higher angle.

[0013] Furthermore, the C-shaped tube has a medium channel located between the inner and outer walls of the C-shaped tube. The outer wall of the C-shaped tube is equipped with a sealing joint that communicates with the medium channel. The inner wall of the C-shaped tube has an opening for the medium channel.

[0014] Furthermore, the side-opening spinal working channel also includes a support for engaging with the outer wall of the C-shaped tube.

[0015] Furthermore, the side-opening spinal working channel also includes an electronic spinal endoscope, and the endoscope channel is used to install the electronic spinal endoscope.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The side-opening spinal working channel provided by this utility model has its own endoscope channel, requiring only one hole to be made in the patient, which helps to reduce incision trauma; in addition, the side opening of the instrument channel allows doctors to directly view the instrument channel and operate surgical instruments more flexibly.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] refer to Figures 1-6 This utility model provides a side-opening spinal working channel, including a support 100, a C-shaped tube 200, and an electronic spinal endoscope 300. The support 100 is used to engage with the outer wall of the C-shaped tube 200.

[0030] In this embodiment, an instrument channel 210 and an endoscope channel 220 are formed on the inner side of the C-shaped tube 200. The endoscope channel 220 is located on the radial side of the instrument channel 210 and is inclined relative to the instrument channel 210. The endoscope channel 220 and the side opening 212 are located on the radial sides of the instrument channel 210, respectively. This arrangement facilitates the insertion of the electronic spinal endoscope 300 towards the instrument channel 210, and the electronic spinal endoscope 300 does not occupy space in the upper part of the instrument channel 210, thus helping to avoid obstructing the insertion of surgical instruments. The product of this embodiment has its own endoscope channel 220 for installing the electronic spinal endoscope 300, so only one hole needs to be made in the patient, which helps to reduce incision trauma.

[0031] In this embodiment, the C-shaped tube 200 has a side opening 212 for the instrument channel 210. This design allows the surgeon to easily visualize the instrument channel 210 and operate the surgical instruments more flexibly during the operation through the side opening 212.

[0032] In the side-opening spinal working channel of this embodiment, the endoscope channel 220 is open on the side facing the instrument channel 210. An anti-rotation limiting channel 230 separates the upper part of the endoscope channel 220 from the upper part of the instrument channel 210, and the lower part of the endoscope channel 220 intersects with the lower part of the instrument channel 210. This arrangement allows for sliding engagement between the anti-rotation limiting channel 230 and the anti-rotation limiting pin 301 of the electronic spinal endoscope 300, ensuring both the insertion of the electronic spinal endoscope 300 and preventing its rotation, thus maintaining a fixed observation direction. Furthermore, the electronic spinal endoscope 300 can be placed at a certain angle (relative to the instrument channel 210), allowing the illumination range or field of view of the electronic spinal endoscope 300 to be better aligned with or cover the surgical site, improving illumination or field of view, and minimizing the space occupied by the instrument channel 210.

[0033] In this embodiment, the inner wall of the C-shaped tube 200 includes a first inner wall 211 for forming an instrument channel 210, a second inner wall 221 for forming an endoscope channel 220, and a third inner wall 231 for forming an anti-rotation limiting channel 230. The second inner wall 221 is recessed relative to the first inner wall 211, and the third inner wall 231 has two opposing sides. The anti-rotation limiting channel 230 is formed between the two third inner walls 231. The width of the anti-rotation limiting channel 230 should be adapted to the width of the anti-rotation limiting pin 301, i.e., the width of the anti-rotation limiting channel 230 is equal to or slightly larger than the width of the anti-rotation limiting pin 301. In this embodiment, the third inner wall 231 is located between the upper part of the first inner wall 211 and the upper part of the second inner wall 221, and the lower part of the first inner wall 211 and the lower part of the second inner wall 221 meet together.

[0034] In this embodiment, one side of the outer wall of the C-shaped tube 200 protrudes to form the outer wall 222 of the endoscope channel 220, and the degree of protrusion of the outer wall 222 gradually decreases from the top to the bottom of the C-shaped tube 200. If the C-shaped tube 200 has a large overall wall thickness, it can still form an instrument channel 210, an endoscope channel 220, and an anti-rotation limiting channel 230 on its inner side, but this would result in a less lightweight and compact design. Therefore, the C-shaped tube 200 has a protrusion on one side of its outer wall to form an outer wall 222, which provides channel space for the endoscope channel 220. Meanwhile, the inner wall 221 of the second channel (i.e., the inner wall of the endoscope channel 220) is relatively concave, allowing the C-shaped tube 200 to maintain a smaller overall wall thickness. Furthermore, the degree of protrusion of the outer wall 222 gradually decreases, which helps to further reduce weight and volume, and minimize the size of the bottom of the C-shaped tube 200 to avoid hindering the insertion and use of the C-shaped tube 200.

[0035] In this embodiment, to further facilitate the insertion and use of the C-shaped tube 200, the bottom end of the C-shaped tube 200 forms an angled angle 240, the position of the endoscope channel 220 corresponds to the lower side of the angled angle 240, and the position of the side opening 212 corresponds to the higher side of the angled angle 240.

[0036] In this embodiment, the C-shaped tube 200 has a media channel 250 located between the inner and outer walls of the C-shaped tube 200. A sealing joint 251 is provided on the outer wall of the C-shaped tube 200, communicating with the media channel 250. An opening 252 of the media channel 250 is provided on the inner wall of the C-shaped tube 200. The sealing joint 251 can be used as a water inlet for cleaning the endoscope lens, or as a negative pressure suction port for drawing out smoke or wastewater. The opening 252 of the media channel 250 is located on the inner wall of the C-shaped tube 200, which helps prevent the opening 252 from being blocked by muscle tissue, thereby preventing muscle tissue from hindering cleaning or suction.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
