Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to a single-port multi-channel surgical device. Background Technology
[0002] Currently, single-port puncture products are mainly divided into two categories: glove-type and silicone-type. Each type has its own advantages and disadvantages. The advantage of the glove-type is that the puncture device is relatively flexible, making it more convenient for the surgeon to operate. However, the flexible puncture device has multiple channels, and when the surgeon operates, the other channels will swing along with it, affecting the operation. The advantage of the silicone-type is that the puncture device has a certain degree of rigidity, and the channels can be set independently on the puncture device platform without affecting each other. However, because the puncture device is more rigid, it can be difficult for the surgeon to operate.
[0003] Therefore, how to reduce the impact of the channel on the operation while reducing the difficulty of operation during single-port surgery has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0004] The purpose of this invention is to provide a single-port multi-channel surgical device to reduce the impact of channels on operation during single-port surgery and reduce the difficulty of operation.
[0005] To achieve the above objectives, the present invention provides a single-port multi-channel surgical device, comprising:
[0006] Fixed chassis;
[0007] A support plate is installed in the middle of the fixed chassis;
[0008] The channel includes at least one endoscope channel and at least one operating channel. The endoscope channel is disposed on the fixed chassis, and the operating channel is disposed on the support plate. The operating channel is movable relative to the fixed chassis.
[0009] In one embodiment of the present invention, the fixed chassis and the support plate are made of flexible materials, wherein the rigidity of the fixed chassis is greater than the rigidity of the support plate.
[0010] In one embodiment of the present invention, the fixed chassis and the support plate are either an integral structure or a separate structure.
[0011] In one embodiment of the present invention, the support plate is a convex structure that protrudes from the fixed chassis in a direction away from the chassis, and all or part of the support plate is deformed so that the operating channel moves relative to the fixed chassis.
[0012] In one embodiment of the present invention, the support plate is rotatable relative to the fixed chassis, and the rotation of the support plate relative to the fixed chassis causes the operating channel to move relative to the fixed chassis.
[0013] In one embodiment of the present invention, the support plate includes a rotating platform, a rotating ring, and a positioning ring, wherein the positioning ring is disposed on the fixed base, the rotating ring is rotatably sleeved on the outer periphery of the positioning ring, and the rotating platform is disposed on the end face of the rotating ring away from the fixed base.
[0014] In one embodiment of the present invention, a sealing ring is provided between the rotating ring and the positioning ring.
[0015] In one embodiment of the present invention, the positioning ring has a retaining edge at one end near the fixed chassis, and the retaining edge is engaged with the fixed chassis; the positioning ring has a protruding ring on the outer periphery of one end away from the fixed chassis, and the rotating ring is fastened to the protruding ring.
[0016] In one embodiment of the present invention, the channel further includes a reserved channel.
[0017] In one embodiment of the present invention, the height of the operating channel is greater than the height of the endoscope channel and the height of the reserved channel.
[0018] In one embodiment of the present invention, the reserved channel is disposed on the fixed chassis or the reserved channel is disposed on the support plate.
[0019] In one embodiment of the present invention, the support plate has a first clearance notch to avoid the reserved channel;
[0020] The endoscope channel is disposed on the fixed chassis, and the support plate has a second clearance notch that avoids the endoscope channel.
[0021] In one embodiment of the present invention, the reserved channel and the endoscope channel are arranged on both sides of the support plate.
[0022] In one embodiment of the present invention, the support plate and the fixed chassis are arranged concentrically or eccentrically.
[0023] In one embodiment of the present invention, an air intake pipe and an exhaust pipe are also provided on the fixed chassis.
[0024] In one embodiment of the present invention, a bayonet is provided on the inner circumference of the fixed chassis, and the cut protective sleeve is fixed by the bayonet.
[0025] In single-port surgery, the fixed base is positioned at the incision site. When the surgeon performs surgery through the operating channel, any external force applied to the operating channel will cause it to move relative to the fixed base, thus reducing the difficulty of the operation. Simultaneously, because the operating channel is mounted on the support plate while the endoscope channel is mounted on the fixed base, the endoscope channel will not interfere with instrument operation during the surgeon's work, thereby minimizing the channel's impact on the procedure during single-port surgery.

Detailed Implementation
[0034] This invention provides a single-port multi-channel surgical device to reduce the impact of channels on the operation during single-port surgery while reducing the difficulty of operation.
[0035] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0036] Please refer to Figures 1 to 6 The single-port multi-channel 300 surgical device disclosed in this invention includes a fixed base 100, a support plate 200, and a channel 300. The support plate 200 is disposed in the middle of the fixed base 100. The channel 300 includes at least one endoscope channel 302 and at least one operating channel 301. The endoscope channel 302 is disposed on the fixed base 100, and the operating channel 301 is disposed on the support plate 200. The operating channel 301 is movable relative to the fixed base 100.
[0037] In single-port surgery, the fixed base 100 is positioned at the incision site. When the surgeon performs surgery through the operating channel 301, an external force acts on the operating channel 301. Under this force, the operating channel 301 can move relative to the fixed base 100, thereby reducing the difficulty of the operation. Simultaneously, since the operating channel 301 is positioned on the support plate 200, and the endoscope channel 302 is positioned on the fixed base 100, the endoscope channel 302 does not interfere with instrument operation during the surgeon's work, thus reducing the impact of the channel 300 on the operation during single-port surgery.
[0038] It should be noted that the function of the endoscope channel 302 is to accommodate the entry and exit of the endoscope; the function of the operating channel 301 is to accommodate the entry and exit of surgical instruments such as scalpels; the function of the fixed base 100 is to support the support plate 200, the operating channel 301, and the endoscope channel 302; and the function of the support plate 200 is to support the operating channel 301. The support plate 200 and the fixed base 100 are either concentrically or eccentrically positioned.
[0039] The movable nature of the operating channel 301 relative to the fixed chassis 100 can be understood as the ability of the operating channel 301 to rotate, tilt, or move relative to the fixed chassis 100 to adjust its operating range. The aforementioned rotation refers to the operating channel 301 being rotatably mounted on the fixed chassis 100, with its rotation center coinciding with its axis, or with the axis of the fixed chassis 100, or with the axis of the support plate 200, etc.; the aforementioned tilting refers to the operating channel 301 tilting due to deformation, or achieving tilting through an inclined connection method, such as a spherical joint connection; the aforementioned movable connection method can be understood as the operating channel 301 being slidably mounted on the fixed chassis 100.
[0040] When the operating channel 301 tilts due to deformation, the operating channel 301 deforms relative to the fixed chassis 100, or the support plate 200 supporting the operating channel 301 deforms relative to the fixed chassis 100.
[0041] In this embodiment of the invention, a preferred example is the deformation of the support plate 200 relative to the fixed base 100. The fixed base 100 and the support plate 200 may be made of the same or different materials. By adjusting the size and density of the fixed base 100 and the support plate 200, the stiffness of the fixed base 100 is made greater than that of the support plate 200. When an external force is applied to the operating channel 301, because the stiffness of the support plate 200 is less than that of the fixed base 100, the connection point between the support plate 200 and the fixed base 100 deforms first, causing the operating channel 301 to tilt relative to the fixed base 100. Optionally, the fixed base 100 and the support plate 200 are made of flexible materials, wherein the stiffness of the fixed base 100 is greater than that of the support plate 200. The flexible material may be rubber, silicone, or similar materials.
[0042] In single-port surgery, the fixed base plate 100 is placed at the incision site. When the surgeon performs surgery through the operating channel 301, an external force is applied to the operating channel 301. When subjected to the external force, because the stiffness of the support plate 200 is less than that of the fixed base plate 100, the operating channel 301 tilts relative to the fixed base plate 100 in the direction of the force. This makes the tilt angle of the operating channel 301 closer to the operating angle of the instrument, thereby reducing the difficulty of the operation.
[0043] The structure of the support plate 200 is not specifically limited; any structure that can easily deform relative to the fixed base 100 is within the scope of protection of this invention. Optionally, the support plate 200 is a convex structure protruding from the fixed base 100 in a direction away from the fixed base 100. All or part of the support plate 200 deforms to allow the operating channel 301 to move relative to the fixed base 100. The convex structure makes the operating channel 301 more easily deformable under external force, allowing the support plate 200 to tilt relative to the fixed base 100 as a whole. Furthermore, the transition area between the operating channel 301 and the convex structure is prone to deformation. This deformation not only allows the operating channel to tilt but also allows it to move inward. In other words, there are two points where the operating channel 301 can tilt relative to the fixed base 100: first, between the support plate 200 and the operating channel 301; and second, between the support plate 200 and the fixed base 100. In single-port surgery, the fixing base 100 is positioned at the incision site. When the surgeon performs surgery through the operating channel 301, an external force is applied to the operating channel 301. Under this force, because the stiffness of the support plate 200 is less than that of the fixing base 100, and the stiffness of the support plate 200 is less than that of the operating channel 301, the operating channel 301 tilts relative to the support plate 200 in the direction of the force. Simultaneously, the support plate 200 also tilts relative to the fixing base 100 in the direction of the force. Ultimately, this tilt angle of the operating channel 301 becomes closer to the operating angle of the instrument, thus reducing the difficulty of the operation. Furthermore, because the support plate 200 has a convex structure, the height of the operating channel 301 relative to the support plate 200 can be adjusted under the influence of external force, bringing the operating channel 301 closer to the surgical site and further reducing the difficulty of the surgery.
[0044] The above description describes tilting through deformation, wherein the fixed base 100 and the support plate 200 are either an integral or separate structure. In the integral structure, the fixed base 100 and the support plate 200 are manufactured simultaneously using a specific process; in the separate structure, the fixed base 100 and the support plate 200 are connected together by welding or bonding. The invention can also generate tilting through rotation. In this case, the fixed base 100 and the support plate 200 are separate structures, and they are fitted together by a spherical joint structure, allowing the operating channel 301 to tilt through rotation.
[0045] This invention also reduces surgical difficulty through rotatability. As described above, when the operating channel 301 is rotatable relative to the fixed base 100, the rotation center of the operating channel 301 coincides with the axis of the operating channel 301, or with the axis of the fixed base 100, or with the axis of the support plate 200, etc.; that is, the operating channel 301 is rotatably mounted on the support plate 200, or the support plate 200 is rotatably mounted on the fixed base 100. The support plate 200 rotates relative to the fixed base 100 to allow the operating channel 301 to move relative to the fixed base 100. When it is necessary to adjust the position of the operating channel 301, the operating channel 301 is moved to the desired position by rotating the support plate 200 or the operating channel 301.
[0046] Taking a rotatable support plate 200 mounted on a fixed base 100 as an example, the support plate 200 includes a rotating platform 201, a rotating ring 202, and a positioning ring 203. The positioning ring 203 is mounted on the fixed base 100, and the rotating ring 202 is rotatably fitted around the outer periphery of the positioning ring 203. The rotating platform 201 is located on the end face of the rotating ring 202 away from the fixed base 100. In single-port surgery, the fixed base 100 is positioned at the incision site. When the surgeon performs surgery through the operating channel 301, and needs to adjust the angle of the operating channel 301 relative to the surgical site, the rotating platform 201 is rotated. Since the rotating platform 201 is fitted around the rotating ring 202, and the rotating ring 202 is rotatably fitted around the positioning ring 203, and the positioning ring 203 is fixed to the fixed base 100, the support plate 200 is rotatably mounted on the fixed base 100, ultimately achieving the purpose of adjusting the angle of the operating channel 301 relative to the fixed base 100, thereby reducing the difficulty of the operation.
[0047] To improve the sealing performance between the support plate 200 and the fixed base plate 100, a sealing structure is provided between the rotating ring 202 and the positioning ring 203. This sealing structure includes a sealing ring 204, a sealing gasket, a sealing ring, and other structures with sealing functions.
[0048] The positioning ring 203 and the fixed chassis 100 can be an integral or separate structure. As long as the connection between the positioning ring 203 and the fixed chassis 100 can be achieved, it is within the protection scope of this invention. When it is a separate structure, the end of the positioning ring 203 near the fixed chassis 100 is provided with a retaining edge, which is engaged with the fixed chassis 100.
[0049] To prevent the rotating ring 202 from moving axially relative to the positioning ring 203, a convex ring is provided on the outer periphery of the end of the positioning ring 203 away from the fixed chassis 100, and the rotating ring 202 is fastened to the convex ring. During installation, an external force is applied to the rotating ring 202, causing the rotating ring 202 to deform and fasten to the convex ring. After the external force is removed, the rotating ring 202 returns to its original deformation and fastens to the convex ring.
[0050] There are many ways to enable the support plate 200 to rotatably mount on the fixed chassis 100, and the embodiments of the present invention are not limited to the above-mentioned forms. When one of the components is damaged, it can be replaced.
[0051] In another embodiment of the present invention, since surgery is sometimes impossible to complete with only one instrument, the channel 300 of the present invention also includes a reserved channel 303 through which auxiliary surgical instruments can enter and exit, thereby facilitating the surgery. The height of the operating channel 301 is greater than the height of the endoscope channel 302 and the reserved channel 303. By setting the height of the operating channel 301 to be greater than that of the endoscope channel 302, the endoscope channel 302 will not obstruct the instruments in the operating channel 301 during single-port surgery.
[0052] The reserved channel 303 is set on the fixed chassis 100 or the reserved channel 303 is set on the support plate 200. When the reserved channel 303 is set on the fixed chassis 100, it can be used as the endoscope channel 302. When the reserved channel 303 is set on the support plate 200, it can be used as the operation channel 301.
[0053] When the reserved channel 303 is installed on the fixed chassis 100, the support plate 200 has a first clearance notch to avoid the reserved channel 303; the endoscope channel 302 is installed on the fixed chassis 100, and the support plate 200 has a second clearance notch to avoid the endoscope channel 302. By setting the first clearance notch and the second clearance notch, it is possible to...
[0054] The aforementioned reserved channel 303 and endoscope channel 302 are arranged on the same side of the support plate 200, or the reserved channel 303 and endoscope channel 302 are arranged on opposite sides of the support plate 200. The corresponding first and second clearance notches are located on the same side of the support plate 200, or the first and second clearance notches are located on opposite sides of the support plate 200.
[0055] Furthermore, since fumes may be generated during the surgical procedure and affect the operating field of vision, in one embodiment of the present invention, the fixed chassis 100 is also provided with an air inlet pipe 400 and an exhaust pipe 500. The air inlet pipe 400 is used to connect to the pneumoperitoneum machine to provide air to the operating space and to exhaust air from the operating space through the exhaust pipe 500.
[0056] A cut-out protective sleeve 600 may also be provided on the fixed chassis 100. The cut-out protective sleeve 600 is fixed to the outer periphery or the inner periphery of the fixed chassis 100. The outer ring of the cut-out protective sleeve 600 is fixed to the outer periphery or the inner periphery of the fixed chassis 100. When fixed to the inner periphery of the fixed chassis 100, a snap-fit 101 is provided on the inner periphery of the fixed chassis 100 to secure the cut-out protective sleeve 600.
[0057] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0058] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
