Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field especially, it relates to a cerebral hemorrhage robot navigation visualization minimally invasive operation special sleeve system. BACKGROUND

[0002] Cerebral hemorrhage is a common form of cerebral stroke, about 10%-15% of cerebral stroke. Because its high mortality and disability rate, has been a major threat to the health of the population. From the perspective of evidence-based medicine, the surgical treatment effect of cerebral hemorrhage is not completely clear at present. Stereotactic catheterization realizes accurate catheterization through millimeter level brain injury, but clinical trials have failed to confirm its efficacy. Hematoma is invisible, and the intraoperative hematoma removal efficiency is low, which may be one of the reasons for this result. In contrast, open endoscopic surgery can significantly improve the intraoperative hematoma removal efficiency. The latest published ENRICH clinical trial verified the efficacy of the surgery on superficial hematoma, but failed to prove its effectiveness on deep hematoma. In the process of reaching deep hematoma, sleeve operation may cause brain vice injury with a diameter of 1-3 centimeters and a depth of 6-7 centimeters, which may be one of the reasons affecting the efficacy of deep hematoma.

[0003] To break through the limitations of the above operation, the team proposed robot navigation visualization minimally invasive aspiration (Robot Assisted Visualized Minimally Invasive Aspiration, RAVMIA). The operation improves the stereotactic catheterization in the following two aspects: first, the robot is used instead of stereotactic navigation, aiming to strictly control the operation path along the long axis of the hematoma; second, the contact visual endoscope is used as an intraoperative monitoring means, aiming to improve the intraoperative hematoma removal rate. However, in the RAVMIA operation, due to the limited operation space, the endoscope and the suction tube can only be placed alternately, and cannot be "seen" and "sucked" at the same time. Therefore, through ingenious integration design, the contact visual endoscope and the suction tube are placed at the same time in the space of 5 millimeters, so that the doctor can "see" and "suck" at the same time, and provide space for flushing and electrocoagulation hemostasis.

[0036] The present application will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present application and implement it, but the embodiments are not as a limitation on the present application.

[0037] The brain hemorrhage robot navigation visual minimally invasive surgery special cannula system aims to cooperate with robot navigation to realize millimeter level secondary injury visual and operation synchronization of brain hemorrhage minimally invasive surgery. The circular contact visual endoscope and the U-shaped side suction pipe are mutually occluded, the relative position is unchanged, so that the aspirator can only suck the visible hematoma and cannot suck the normal brain tissue, greatly increasing the safety of the operation. Through the ingenious design in the small space, the four requirements of seeing, flushing, sucking and coagulating during hemostasis are met at the same time.

[0038] In the brain hemorrhage minimally invasive surgery, the cannula system is combined with robot navigation. The robot navigation system provides accurate surgical path planning and positioning to guide the cannula system to accurately reach the brain hemorrhage site. Specifically, referring to Figure 1 , the brain hemorrhage robot navigation visual minimally invasive surgery special cannula system comprises:

[0039] The contact visual cannula 100 is formed with an endoscope channel 110, a U-shaped pipe channel 120 and a flushing channel 130. Among them, the contact visual cannula 100 provides the main channel structure for the operation. The endoscope channel 110 is used to place the electronic endoscope, and the visualization observation of the operation site is realized through the electronic endoscope. Since the endoscope channel 110 is designed to be transparent at one end, the electronic endoscope can clearly observe the operation area on the blind side, providing real-time image information for the doctor.

[0040] Referring to Figure 2 and Figure 3 , in a feasible implementation, the shape of the U-shaped pipe is a concave tubular channel closely tangent to the circular endoscope channel 110, and the flushing channel 130 is arranged on both sides of the circular endoscope channel 110. The U-shaped pipe channel 120 closely cooperates with the endoscope channel 110. This close tangent design can make the whole structure more compact, save space, and also may help to improve the stability and reliability of the equipment.

[0041] Referring to Figure 3 , the shape of the U-shaped pipe is a concave tubular channel, which is helpful to guide the flow of liquid or other substances, and facilitates the operation of suction or flushing. The flushing channel 130 is arranged on both sides of the circular endoscope channel 110, which can make the flushing channel 130 closer to the operation area, improve the flushing effect. At the same time, the flushing channels 130 arranged on both sides can provide more uniform flushing water flow, ensuring the cleanliness of the operation area.

[0042] Referring to Figure 3The flushing channel 130 is a triangle-like channel, and the thickness of the outer wall of the triangle-like channel near the side of the contact visual cannula 100 is the same as that of the inner mirror channel 110 and the U-shaped tube channel 120 near the side of the contact visual cannula 100. The flushing channel 130 is a triangle-like channel, which has the stability of a triangle and can make the flushing channel 130 more solid during use and not easy to deform. The shape of the triangle also helps to control the direction and speed of the flushing water flow, improving the efficiency of flushing.

[0043] The thickness of the outer wall of the triangle-like channel near the side of the contact visual cannula 100 is the same as that of the inner mirror channel 110 and the U-shaped tube channel 120 near the side of the contact visual cannula 100, which can make the entire structure have a consistent thickness on the outer wall of the side of the contact visual cannula 100, improving the overall integrity and aesthetics of the equipment. The same thickness also helps to improve the strength and durability of the equipment and reduce the risk of breakage or damage during use.

[0044] It should be noted that in the brain hemorrhage robot navigation visualization minimally invasive surgery special cannula system, the "blind end transparency" refers to the end of the inner mirror channel 110 of the contact visual cannula 100 is designed as a closed blind end, and this blind end part is made of transparent material. On the one hand, the blind end can prevent the electronic endoscope from inserting too deeply into the inner mirror channel 110 and causing unnecessary damage to the tissue, serving as a certain limiting function. On the other hand, due to the blind end transparency, when the electronic endoscope is placed in the inner mirror channel 110 and near the blind end, the situation in a certain direction of the surgical area can be clearly observed through the transparent blind end. For example, the tissue near the front end of the cannula, the hematoma, etc. can be better observed, providing the doctor with a more accurate surgical field of view, which helps the doctor to perform more precise operations and judgments.

[0045] It should be noted that the electronic endoscope is detachably placed in the inner mirror channel 110 for visual operation. The electronic endoscope works in the inner mirror channel 110 of the contact visual cannula 100, and transmits the image of the surgical site to the display in real time, allowing the doctor to clearly observe the situation of the surgical area, including the position, size of the hematoma, and the state of the surrounding tissue, etc. The doctor can perform precise surgical operations according to the image information provided by the electronic endoscope.

[0046] It should be noted that a single-sided hole 1211 is provided at one end of the side suction U-shaped tube 121, which is used for absorbing liquid, and the side suction U-shaped tube 121 is detachably placed in the U-shaped tube channel 120. The U-shaped tube channel 120 of the contact visual cannula 100 can accommodate different functional U-shaped tubes such as the side suction U-shaped tube 121, the electrocoagulation U-shaped tube, and the spraying U-shaped tube. These U-shaped tubes are switched or work cooperatively according to the needs of the operation.

[0047] In the technical solution, one end of the side suction U-shaped tube 121 is a blind end, and a one-sided hole 1211 is formed in the recess on one side of the blind end of the side suction U-shaped tube 121.

[0048] The one-sided hole 1211 is formed in the recess on one side of the blind end of the side suction U-shaped tube 121, which is used to absorb liquid such as blood, cerebrospinal fluid, etc. at the surgical site. The side suction U-shaped tube 121 can control or adjust the negative pressure in the tube by connecting a controllable negative pressure device, so as to realize precise suction of the liquid. During the operation, the doctor can adjust the size of the negative pressure according to the needs to ensure effective removal of the liquid while avoiding damage to the surrounding tissues.

[0049] The length of the side suction U-shaped tube 121 is greater than the length of the contact visualizing cannula 100, and the one-sided hole 1211 is exposed outside the contact visualizing cannula 100.

[0050] The one-sided hole 1211 is formed in the recess, on one hand, when the blind end of the endoscope channel 110 contacts the blood or wound, etc., the length of the recess structure of the side suction U-shaped tube 121 is greater than the contactable length of the blind end of the endoscope channel 110, and the liquid at the wound is drained to the one-sided hole 1211 in the recess structure of the side suction U-shaped tube 121, which can improve the efficiency and accuracy of liquid suction. On the other hand, the one-sided hole 1211 is arranged in the recess to a certain extent to play a protective role, reducing the risk of the hole being blocked, and also avoiding the one-sided hole 1211 from being damaged by excessive friction or collision with the surrounding tissues during the operation.

[0051] As shown in Figure 1 , the overall length of the side suction U-shaped tube 121 is longer than the contact visualizing cannula 100, so that the one-sided hole 1211 at one end of the side suction U-shaped tube 121 can extend out of the range of the contact visualizing cannula 100 and be in an exposed state. Specifically, the one-sided hole 1211 is exposed outside the contact visualizing cannula 100, which can more accurately position to the specific position where the liquid needs to be sucked. Through the cooperation of the length of the side suction U-shaped tube 121 and the blind end of the endoscope channel 110, the effect of seeing and sucking can be realized, which can effectively suck the liquid in the contact visualizing endoscope out of the body through the side suction U-shaped tube 121, as shown in Figure 1 , the liquid or hematoma is led out of the body along the direction of the arrow shown in the figure, which ensures efficient suction of the liquid such as blood, cerebrospinal fluid, etc. in the specific area of visualization, and improves the cleanliness and visibility of the operation.

[0052] As shown in Figure 3 , the recess of the side suction U-shaped tube 121 is in close contact with the outer edge of the endoscope channel 110 in a half-wrapping manner, and the relative position relationship between the side suction U-shaped tube 121 and the endoscope channel 110 is unchanged and cannot be rotated separately; the side suction U-shaped tube 121 is used to suck the hematoma that can be seen by the contact visualizing endoscope.

[0053] It should be noted that, due to the close contact between the groove of the side suction U-shaped tube 121 and the outer edge of the endoscope channel 110 in a semi-encircling manner, the relative positional relationship between the two is fixed, and accidental relative rotation will not occur during the operation, thereby ensuring the stability of the operation. Doctors do not need to worry about the change of the position of the two components affecting the operation field and the accuracy of the operation, and can focus more on the operation. In addition, the fixed relative positional relationship helps to improve the accuracy of hematoma suction. Doctors can accurately determine the position of the hematoma according to the visual information provided by the endoscope channel 110, and the side suction U-shaped tube 121 can more accurately suction the hematoma in contact with the endoscope due to the close contact and fixed position of the endoscope channel 110, thereby improving the efficiency and success rate of the operation. During the operation, especially when dealing with sensitive parts such as cerebral hemorrhage, any unnecessary movement may have serious consequences. It avoids accidental damage to the surrounding tissues caused by the relative movement of the side suction U-shaped tube 121 and the endoscope channel 110, reduces the risk of the operation, and improves the safety of the operation. At the same time, the side suction U-shaped tube 121 can always be kept in the right position to effectively suction the hematoma, without affecting the suction effect due to the change of position, thereby providing a reliable guarantee for the smooth progress of the operation and ensuring the reliability of the suction function.

[0054] The application refers to a special cannula system for brain hemorrhage robot navigation visualization minimally invasive surgery, which comprises a contact visualization cannula 100 formed with an endoscope channel 110, a U-shaped tube channel 120 and a flushing channel 130. The endoscope channel 110 is used for placing an electronic endoscope, and one end is designed as a blind end. The electronic endoscope works in the channel to transmit the image of the operation site to the display in real time, so that the doctor can clearly observe the situation of the operation area, including the position, size and surrounding tissue state of the hematoma. The U-shaped tube channel 120 is closely tangent to the endoscope channel 110 and can accommodate different functional U-shaped tubes such as side suction U-shaped tube 121, electrocoagulation U-shaped tube and spraying U-shaped tube, which can be switched or cooperatively work according to the operation needs. The flushing channel 130 is provided on both sides of the circular endoscope channel 110 and is a triangle-like channel, and the outer wall near one side of the contact visualization cannula 100 has the same thickness as the outer wall of the endoscope channel 110 and the U-shaped tube channel 120 on this side. The side suction U-shaped tube 121 has a blind end, and a single-sided hole 1211 is provided in the recess on one side of the blind end for absorbing liquid such as blood and cerebrospinal fluid at the operation site. The length of the side suction U-shaped tube 121 is greater than the length of the contact visualization cannula 100, and the single-sided hole 1211 is exposed outside the contact visualization cannula 100, so that the position of the liquid can be more accurately positioned, and the liquid in the visualization area can be sucked out of the body in cooperation with the endoscope channel 110.

[0055] The present application ensures that the cannula system accurately reaches the cerebral hemorrhage site through a robot navigation system, improving the accuracy of the operation. The blind end of the endoscope channel 110 and the electronic endoscope provide real-time image information, allowing the doctor to more accurately understand the situation in the operation area and make accurate operations and judgments. The multi-channel design of the contact visual cannula 100 makes the layout of the surgical instruments more compact, saving space and improving the stability and reliability of the equipment. Among them, the triangle-shaped flushing channel 130 has stability, making the flushing channel 130 more solid and not easy to deform, while helping to control the direction and speed of the flushing water flow and improve the flushing efficiency. The same thickness of the outer wall improves the integrity, aesthetics, strength and durability of the equipment, reducing the risk of rupture or damage during use. The see-and-suck function ensures efficient suction of liquid in the visualized specific area, improving the cleanliness and visibility of the operation.

[0058] It should be noted that the difference between the general cannula and the contact visual cannula 100 is that the endoscope channel 110 port is open, and the cylindrical bipolar electrocoagulation is placed in the U-shaped channel of the general cannula.
