Description

Navigation visual minimally invasive surgery special sleeve system for cerebral hemorrhage robot

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a cerebral hemorrhage robot navigation visualization sleeve system special for minimally invasive surgery.

Background

Cerebral hemorrhage is a common form of cerebral apoplexy, accounting for about 10% -15% of cerebral apoplexy. Due to its high mortality and disability rate, it has been a major threat to the health of the population. From the point of view of evidence-based medicine, the surgical treatment effect of cerebral hemorrhage is currently still not completely clear. Stereotactic catheterization achieves accurate catheterization through millimeter-scale brain injury, but clinical trials have failed to confirm its efficacy. Invisible hematoma and low intraoperative hematoma clearance efficiency may be one of the reasons for this result. In contrast, open endoscopic surgery can significantly improve the efficiency of intraoperative hematoma clearance for visualization of hematoma. The recently published ENRICH clinical trial verifies the efficacy of this procedure on superficial hematomas, but fails to demonstrate its effectiveness on deep hematomas. In the process of reaching deep hematoma, the sleeve operation may cause brain collateral injury with the diameter of 1-3 cm and the depth of 6-7 cm, which may be one of reasons for influencing the curative effect of the deep hematoma.

In order to break through the limitations of the above described surgical technique, robotic navigation visualization minimally invasive aspiration techniques (RobotAssistedVisualizedMinimally InvasiveAspiration, RAVMIA) have been proposed by the team. The three-dimensional directional catheterization is improved in two aspects, namely firstly, a robot is used for replacing three-dimensional directional navigation to strictly control the entry of a surgical path along the long axis of hematoma, and secondly, a contact type visual endoscope is used as an intra-operative monitoring means to improve the clearance rate of the hematoma during the operation. However, in RAVMIA procedures, due to the limited space available for manipulation, the endoscope and suction tube can only be placed alternately, and cannot be "seen" and "sucked" simultaneously. Therefore, there is a need for a simultaneous placement of a contact visualization endoscope and a suction tube in a 5 mm space through a smart integrated design that allows the physician to "look" at "suction" while providing space for irrigation and electrocoagulation hemostasis.

Detailed Description

The present utility model will be further described with reference to the accompanying drawings and specific examples, which are not intended to be limiting, so that those skilled in the art will better understand the utility model and practice it.

The invention discloses a sleeve system special for cerebral hemorrhage robot navigation visualization minimally invasive surgery, which aims to realize visual and operation synchronization cerebral hemorrhage minimally invasive surgery under millimeter-level auxiliary injury by matching with robot navigation. The visual endoscope is meshed with the U-shaped side suction tube through circular contact, and the relative position is unchanged, so that the aspirator can only suck the hematoma which is seen and can not suck normal brain tissues, and the safety of the operation is greatly improved. Through ingenious design in the tiny space, four requirements of flushing, sucking and coagulating when stopping bleeding are met.

In minimally invasive cerebral hemorrhage surgery, the cannula system is combined with robotic navigation. The robotic navigation system provides accurate surgical path planning and positioning, guiding the cannula system to accurately reach the cerebral hemorrhage site. Specifically, referring to fig. 1, the utility model relates to a cerebral hemorrhage robot navigation visualization minimally invasive surgery special sleeve system, which comprises:

The contact visual cannula 100 is formed with an endoscope channel 110, a U-shaped tube channel 120, and a flush channel 130. Wherein contact visualization sleeve 100 provides the primary channel structure for surgery. The endoscope channel 110 is used for placing an electronic endoscope through which visual observation of the surgical site is achieved. Because one end of the endoscope channel 110 is designed to be transparent at the blind end, the electronic endoscope can clearly observe the operation area at the blind end side, and real-time image information is provided for doctors.

Referring to fig. 2 and 3, in one possible embodiment, the U-tube is shaped as a concave tubular channel closely tangential to the circular endoscope channel 110, with irrigation channels 130 open on both sides of the circular endoscope channel 110. The U-shaped tube channel 120 mates with the endoscope channel 110. The tightly tangent design can make the whole structure more compact, save space, and can also help to improve the stability and reliability of the equipment.

Referring to fig. 3, the u-shaped tube is shaped as a concave tubular channel to help guide the flow of liquid or other substances, facilitating the aspiration or irrigation operations. The two sides of the circular endoscope channel 110 are provided with the flushing channel 130, and the flushing channel 130 can be more close to an operation area by the arrangement, so that the flushing effect is improved. At the same time, the provision of the irrigation channels 130 on both sides may provide a more uniform irrigation flow, ensuring cleanliness of the surgical field.

Referring to fig. 3, the flushing channel 130 is a triangle-like channel, and the outer wall of the triangle-like channel near the side contacting the viewing cannula 100 is the same thickness as the outer walls of the endoscopic channel 110 and the U-shaped tube channel 120 near the side contacting the viewing cannula 100. The flushing channel 130 is a triangle-like channel, has triangle stability, and can make the flushing channel 130 stronger and not easy to deform in the use process. The triangular shape also helps to control the direction and speed of the flushing water flow, improving the flushing efficiency.

The thickness of the outer wall of the side, close to the contact visual sleeve 100, of the triangle-like channel is the same as that of the outer walls of the side, close to the contact visual sleeve 100, of the endoscope channel 110 and the U-shaped tube channel 120, so that the thickness of the outer wall of the whole structure, close to the contact visual sleeve 100, can be kept consistent, and the integrity and the attractiveness of the equipment are improved. The same thickness also helps to increase the strength and durability of the device, reducing the risk of cracking or damage during use.

In the cannula system special for cerebral hemorrhage robot navigation visualization minimally invasive surgery, "blind end transparency" means that one end of the endoscope channel 110 contacting the visualization cannula 100 is designed as a closed blind end, and the blind end portion is made of transparent material. On the one hand, the blind end can prevent the electronic endoscope from being excessively deep when being inserted into the endoscope channel 110 to cause unnecessary damage to tissues, and plays a certain limiting role. On the other hand, due to the transparency of the blind end, when the electronic endoscope is placed in the endoscope channel 110 and approaches the blind end, the situation of the specific direction of the operation area can be clearly observed through the transparent blind end. For example, tissue, hematoma and the like near the front end of the cannula can be better observed, a more accurate surgical field is provided for a doctor, and more accurate operation and judgment can be facilitated for the doctor.

It should be noted that the electronic endoscope is detachably disposed in the endoscope channel 110 for performing a visual operation. The electronic endoscope operates in the endoscope channel 110 that contacts the visual cannula 100, transmitting the image of the surgical site to the display in real time, allowing the physician to clearly view the condition of the surgical area, including the location, size, and status of surrounding tissue, etc. A doctor can perform an accurate surgical operation based on image information provided by the electronic endoscope.

It should be noted that, a single-side hole 1211 is formed at one end of the side suction U-shaped tube 121, the single-side hole 1211 is used for absorbing liquid, and the side suction U-shaped tube 121 is detachably disposed in the U-shaped tube channel 120. The U-shaped tube channel 120 contacting the viewing cannula 100 may accommodate U-shaped tubes of different functions, such as side-suction U-shaped tube 121, electrocoagulation U-shaped tube, and spray U-shaped tube. These U-tubes are switched or co-operate as required by the procedure.

In this embodiment, one end of the side suction U-shaped tube 121 is a blind end, and a single side hole 1211 is formed in a recess on one side of the blind end of the side suction U-shaped tube 121.

A single side hole 1211 is provided in the recess on the blind end side of the side suction U-shaped tube 121 for absorbing fluids such as blood, cerebrospinal fluid, etc. at the surgical site. The side suction U-shaped pipe 121 can control or regulate the negative pressure in the pipe by connecting a controllable negative pressure device, thereby realizing accurate suction of liquid. In the operation process, doctors can adjust the negative pressure according to the needs to ensure that the liquid is effectively removed and simultaneously avoid damaging surrounding tissues.

The length of the side suction U-shaped tube 121 is longer than the length of the contact visual sleeve 100, and the single-sided hole 1211 is exposed outside the contact visual sleeve 100.

On the one hand, the blind end of the endoscope channel 110 contacts with blood or a wound, and the like, the length of the concave structure of the side suction U-shaped tube 121 is longer than the contactable length of the blind end of the endoscope channel 110, and liquid at the wound is drained to the single-side hole 1211 in the concave structure by the concave structure of the side suction U-shaped tube 121, so that the efficiency and accuracy of liquid suction can be improved. On the other hand, the provision of the single-sided apertures 1211 within the recess provides some protection, reducing the risk of the apertures being blocked, while also potentially avoiding damage to the single-sided apertures 1211 by accidental excessive rubbing or collision with surrounding tissue during operation.

As shown in fig. 1, the overall length of the side suction U-shaped tube 121 is longer than that of the contact visual sleeve 100, so that the single-sided hole 1211 at one end of the side suction U-shaped tube 121 can be extended beyond the extent of contact visual sleeve 100 in an exposed state. In particular, the single-sided aperture 1211 is exposed outside of the contact visualization sleeve 100, and on the one hand can be more accurately positioned to a specific location where liquid needs to be aspirated. Through the cooperation of the length of the side-suction U-shaped pipe 121 and the blind end of the endoscope channel 110, the effect of instant suction can be realized, liquid in the contact visualization of the endoscope channel 110 is effectively and directly sucked out of the body through the side-suction U-shaped pipe 121, and referring to fig. 1, liquid or hematoma is led out of the body along the direction of an arrow in the drawing, so that the high-efficiency suction of the liquid such as blood, cerebrospinal fluid and the like in a specific visualized area is ensured, and the cleanliness and the visibility of an operation are improved.

Referring to fig. 3, the groove of the side suction U-shaped tube 121 is in semi-wrapping tight contact with the outer edge of the endoscope channel 110, the relative positional relationship between the side suction U-shaped tube 121 and the endoscope channel 110 is unchanged and cannot rotate separately, and the side suction U-shaped tube 121 is used for sucking hematoma seen by a contact visual endoscope.

It should be noted that, since the groove of the side suction U-shaped tube 121 is in close contact with the outer edge of the endoscope channel 110 in a semi-wrapping manner, the relative positional relationship between the groove and the outer edge is fixed, and no unexpected relative rotation occurs during the operation, thereby ensuring the stability of the operation. The doctor does not need to worry about the influence of the position change of the two parts on the operation vision and the operation precision in the use process, and can more concentrate on the operation. In addition, the fixed relative positional relationship helps to improve the accuracy of hematoma aspiration. The doctor can accurately judge the position of hematoma according to the visual information provided by the endoscope channel 110, and the side suction U-shaped tube 121 can more accurately suck hematoma seen by the visual endoscope due to the close contact and the fixed position with the endoscope channel 110, so that the efficiency and the success rate of the operation are improved. Any unnecessary movement can have serious consequences during surgery, especially when dealing with sensitive sites such as cerebral hemorrhage. It avoids accidental damage to surrounding tissue that may result from relative movement of the side-suction U-tube 121 and the endoscope channel 110, reduces the risk of surgery, and improves the safety of surgery. Meanwhile, the side suction U-shaped tube 121 can be always kept at a proper position, hematoma is effectively sucked, the suction effect is not affected due to position change, reliable guarantee is provided for smooth operation, and the reliability of the suction function is ensured.

The application relates to a cerebral hemorrhage robot navigation visualization minimally invasive surgery special sleeve system, which comprises a contact visualization sleeve 100, wherein an endoscope channel 110, a U-shaped tube channel 120 and a flushing channel 130 are formed in the contact visualization sleeve. The endoscope channel 110 is used for placing an electronic endoscope, and one end is designed for blind end transparency. The electronic endoscope works in the channel, the image of the operation part is transmitted to the display in real time, and a doctor can clearly observe the condition of the operation area, including the position, the size, the surrounding tissue state and the like of hematoma. The U-shaped tube channel 120 is closely tangent to the endoscope channel 110, and can accommodate U-shaped tubes with different functions such as a side suction U-shaped tube 121, an electrocoagulation U-shaped tube, a spraying U-shaped tube and the like, and can be switched or cooperatively operated according to the operation requirement. The flushing channel 130 is formed on two sides of the circular endoscope channel 110, and is a triangle-like channel, and the thickness of the outer wall of the side close to the contact visual sleeve 100 is the same as that of the outer walls of the side of the endoscope channel 110 and the U-shaped tube channel 120. Wherein, one end of the side suction U-shaped tube 121 is a blind end, and a single side hole 1211 is arranged in a recess at one side of the blind end for absorbing liquid at the operation site, such as blood, cerebrospinal fluid and the like. The length of the side suction U-shaped pipe 121 is larger than that of the contact visual sleeve 100, and the single-side hole 1211 is exposed outside the contact visual sleeve 100, so that the liquid suction position can be more accurately positioned, and the liquid in the visual area can be sucked out of the body by being matched with the endoscope channel 110.

According to the application, the accurate arrival of the sleeve system at the cerebral hemorrhage position is ensured by the robot navigation system, and the accuracy of the operation is improved. Real-time image information is provided through the endoscope channel 110 at the blind end and the electronic endoscope, so that a doctor can more accurately know the condition of the operation area and perform accurate operation and judgment. The use of the multi-channel design of the contact visualization sleeve 100 allows for a more compact surgical instrument layout, space saving, and improved stability and reliability of the device. The triangle-like flushing channel 130 has stability, so that the flushing channel 130 is stronger and is not easy to deform, and meanwhile, the flushing channel is beneficial to controlling the direction and speed of flushing water flow and improving flushing efficiency. The outer wall of the same thickness improves the integrity, aesthetics, strength and durability of the device, reducing the risk of cracking or damage during use. The function of looking and sucking ensures that the liquid in a specific visualized area is efficiently sucked, and the cleanliness and the visibility of the operation are improved.
