Description
Technical Field
The invention relates to a large-channel full-field intervertebral disc mirror body and a sleeve used for spine minimally invasive surgery, an imaging and light source system with the sleeve, and particularly relates to a large-diameter working sleeve.
Background
Minimally invasive spinal surgery is increasingly being performed without imaging endoscopic systems. Existing spinal endoscopes include intervertebral disc mirrors and intervertebral foraminicopes.
Discoscope operation principle: the working cannula is placed into the intervertebral disc, a part of the vertebral lamina is removed under the direct vision of the endoscope, the nerve root is exposed, the herniated nucleus pulposus tissue is removed, the incision is about 1.8 cm, and the endoscope lens is stretched into the cannula and fixed at the top end of the cannula during operation, so that a stable visual field is provided. The mode has the major defects that the air is used as a medium, and the blood of the wound easily contaminates the lens, so that the visual field is unclear, the operation needs to be suspended, and the wound is cleaned. The advantages are that: the operation space is large, and particularly various tools can enter the wound without limitation basically, so that the difficulty of operation can be reduced. The support is reasonably utilized, the single person operation space is larger, the operation is convenient, and for an operator, only the operation problem needs to be considered, and the endoscope does not need to be held by hands basically.
Principles of foramen mirror surgery: the working cannula is passed through a small incision from the safe area behind or laterally of the patient's body into the intervertebral foramen or disc space, and then a coaxial endoscope is placed from the working cannula to perform the procedure around the disc herniation. The advantage is that water is used as medium, and flowing water can ensure clean visual field, and avoid dirty visual field caused by blood sticking to lens. The disadvantage is that the instrument channel is only 3-5 mm, the operation space is small, and the conventional decompression fusion large-size tool can not be placed under the direct vision of the endoscope.
Some patients with herniated disk and spinal stenosis incorporate unstable spine, and simple decompression is insufficient, at this time, fusion fixation is also needed, and the existing under-scope interbody fusion cage is not placed under full vision of an endoscope, but is placed under X-ray of a C-arm, so that the X-ray perspective nerve dura sac is not developed, and whether critical tissues such as the nerve dura sac can be damaged in operation or not can not be monitored.
Therefore, it is critical how to ensure that a large endoscope sleeve is placed into a conventional open surgical tool, that a safe minimally invasive insertion of an interbody fusion cage is performed, and that a clear surgical field of view is ensured.

Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only and are not meant to be the only embodiment.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
The present application adds water inlet and outlet means within the sleeve 10, and fills the sleeve 10 or at the operating area with water as a medium, rather than air as a medium for the field of view. Thus, the wound bleeding can be quickly diluted and discharged by water, the endoscope lens cannot be stained, and a good visual field is maintained.
Embodiment one: 1-6, a fully-closed water medium intervertebral disc mirror operation sleeve for minimally invasive spinal column comprises a tube body 10, wherein the tube body 10 can be a metal tube, is cylindrical, and can be flat or beveled at the bottom end;
a water inlet and outlet assembly 50 is fixed on the pipe body 10;
the water inlet and outlet assembly 50 is used for water inlet and water outlet into the pipe body 10;
the water inlet and outlet assembly 50 comprises a water inlet pipe 51, a water inlet 511, a water outlet 52 and a water outlet 521, wherein the water inlet pipe 51 is fixed on the pipe body 10, the bottom end of the water inlet pipe 51 is communicated with the bottom of the pipe body 10, and is 3-8mm away from the bottom edge of the pipe body 10, a certain distance is reserved between the water inlet pipe and the bottom end of the pipe body 10, so that water inlet does not directly wash a wound, but forms water column with the same diameter as the inner diameter of the pipe body 10 to wash blood of a diluted wound, and the blood can be diluted and washed more quickly for bleeding possibly occurring randomly;
the connection part of the water inlet pipe 51 and the pipe body 10 is tangent with the inner wall of the pipe body 10 to form a water inlet 511; the tangential water inlet forms a rotary water flow, so that the dilution effect of blood is better;
2-4 water inlets 511; the plurality of water inlets are used for ensuring the stability of water inlet rotation;
The drain pipe 52 is fixed on the pipe body 10, the bottom end of the drain pipe 52 is communicated with the top of the pipe body 10, the communicating position is 6-12mm away from the top edge of the pipe body 10, and the communicating position of the drain pipe 51 and the pipe body 10 is tangent to the inner wall of the pipe body 10 to form a drain outlet 521. 2-4 water outlets 521; the maximum inner diameter of the water outlet is 3mm. The plurality of water outlets is also used for ensuring the stability of water flow.
When the pipe body 10 is used, the pipe body 10 is inserted into a wound, the water inlet equipment and the water discharge equipment are started, and the water discharge port 521 is at a certain distance from the top end of the pipe body 10, so that the liquid level can be maintained at the water discharge port when the water discharge amount is the same or larger than the water inlet amount. This allows a clear view and leaves the tube 10 a very wide operating space.
Embodiment two: of course, in one embodiment, the water flow speed is low, the rotating speed of the water flow is high, a vortex can be formed at the liquid level, the operation of the instrument is not facilitated, and the instrument can be collided, so that liquid is splashed.
Thus, a top cover is additionally installed on top of the tube body 10. The cap 60 is used to seal the top surface of the tube body 10 while providing access for the operating instruments to the cannula; after the top cover is sealed, the water inflow and flow rate of water flow can be increased without worrying about splashing, and the water in the pipe body 10 can not influence the visual field definition of the bottom even if the flow speed is very fast even if the water is directly filled with the liquid level on the bottom surface of the top cover.
The top cover 60 includes a fixing portion, a top film, a first inlet 61 and a second inlet 62;
The fixing part is used for sealing and fixing the top cover 60 and the pipe body 10, and is cylindrical and detachably sealed and fixed with the fixing part of the pipe body 10; the fixing part can be a cylindrical pipe with internal threads and is directly screwed on the pipe body 10, so that the pipe is convenient and quick;
the top film is used for sealing the top opening of the pipe body 10, a plurality of inlets are fixedly formed in the top film, and the top film is a rubber film; the rubber for the top film is mainly used for providing elastic deformation and avoiding water outflow.
The inlet serves as a passage for the endoscope 70 and the operating instrument into the tube body 10;
The inlet inner diameter is smaller than the outer diameter of the inner diameter mirror 70 and the part of the operating device extending into the pipe body 10; because the top film is elastic and has an inner diameter smaller than the outer diameter of the device, an effective seal can be formed to avoid water spillage in the state of filling the tube body 10 with water.
When in use, when the device needs to be stretched in or stretched out, the liquid level is preferably adjusted to be slightly lower than the position of the top film, so that water is prevented from being carried out.
Embodiment III: it is also necessary to distinguish between actual manufacturing or design of the portal, where the endoscope 70 extends into the tube 10, and where the diameter is the same from top to bottom, and where there is substantially no movement of position within the tube 10.
Thus, the design inlet comprises a first inlet 61;
the first inlet 61 serves as a passage for an endoscope into the tube 10;
the first inlet 61 comprises a guide pipe, the guide pipe comprises a hard part and an elastic part, and the elastic part is fixed at the bottom end of the hard part;
the hard part extends into the lower side of the top film, the extending part is 3-5mm, and the inner diameter of the hard part is larger than the outer diameter of the part of the endoscope 70 extending into the tube body 10;
the top end of the elastic part is communicated with the hard part, the inner diameter of the top end of the elastic part is the same as that of the hard part, and the inner diameter of the bottom end of the elastic part is smaller than the outer diameter of the part of the endoscope 70 extending into the tube body 10.
Embodiment four: for instruments, the shapes are usually different in size, and more importantly, the shapes of the operation ends of the instruments are irregular, such as drills, cutters, chisels and the like, if the elastic parts are arranged at the bottom ends of the inlets, the elastic parts are likely to be torn, so that poor sealing is caused or fragments fall into wounds.
Thus, the inlet includes a second inlet 62;
The second inlet 62 serves as a passage for an operating instrument into the tubular body 10;
The second inlet 62 includes a hard sheet 621 and an elastic tube 622, the hard sheet 621 is a plastic sheet, a portion of the hard sheet 621 is fixedly connected with the elastic tube 622, the hard sheet 621 is staggered and overlapped with an adjacent hard sheet, the hard sheet 621 is fully distributed on the inner wall of the elastic tube 622, and at least 1/3 of the second inlet 62 extends below the top film.
However, in order to improve the sealing effect, a sealing sleeve 623 is fixed to the top of the portion of the top film for tightly fitting the rod of the instrument to form a water seal.
Fifth embodiment: the device also comprises a bottom sleeve 20, wherein the bottom sleeve 20 is made of soft materials and is used for forming a tightly attached boundary when the sleeve is abutted against the spine and human tissues;
the bottom sleeve 20 is annular and coaxial with the sleeve 20, and the axial maximum length is 15mm.
Example six: the single-layer bottom cover 20 does not seal the wound bottom well, and water may flow out from the bottom of the tube body 10 along the inner wall of the wound when the water flow speed is high or the water pressure is high. The bottom sleeve 20 is thus designed in two layers, comprising an annular inner bottom sleeve 21 and an outer bottom sleeve 22;
The axial length of the inner bottom sleeve 21 is 6-9mm, and the axial length of the outer bottom sleeve 22 is 15mm;
A gap of 2-5mm is formed between the inner bottom sleeve 21 and the outer bottom sleeve 22;
also comprising a suction pipe 40 and a bleed ring 41;
The bottom end of the air suction pipe 40 is communicated with an air entraining ring 41, the air entraining ring 41 is fixed at the bottom edge of the pipe sleeve 10, and the bottom surface of the air entraining ring is provided with an annular air entraining through groove;
