Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a blood vessel blocking device and method used in conjunction with a laparoscope. Background Art

[0002] Portal blockade includes hepatic blood flow blockade, whole liver blood flow blockade, hepatic vein blockade, etc. Portal blockade is mainly performed during local resection of liver lesions or regular liver segment and lobe resection to reduce liver bleeding and minimize intraoperative surgical risks and the incidence of postoperative liver failure. Although portal blockade can reduce intraoperative bleeding, it may cause ischemia-reperfusion injury to liver cells, especially for patients with underlying liver disease and long blockade time. The risk of postoperative liver failure will increase significantly. Therefore, the duration of portal blockade should be controlled according to the specific situation of the liver. If the operation cannot be completed in one blockade, multiple blockades can be considered, which is safer.

[0003] 1. The most widely used laparoscopic portal obstruction device is the portal obstruction band. When the portal vessels are blocked, the blocking device is difficult to operate and is not convenient for rapid blocking of the vessels. 2.

First, after the bottom plate and the pressure plate are respectively arranged above and below the table for supporting the overall device, the pressure plate can be pressed downward, and the table can be clamped and positioned by using two fixed clamping pads, so that the overall device can be supported and positioned. When the pressure plate moves downward, the sliding cooperation of the slide rail and the two slide plates can drive the rotating rod to rotate downward, and after the table is clamped and positioned, the second plug rod can be released, and the second tension spring in a stressed state can pull the second plug rod to move, so that the second plug rod and the corresponding second plug hole can be clamped, so that the arc-shaped positioning rod can be positioned, and the rotating rod can be further positioned, so that the pressure plate can be stably limited; S2, when the support tube is inserted into the docking ring, the ball can roll along the inclined surface of the conical clamping ring, and at this time, the transmission plate can be pushed to move to the side away from the support tube, thereby compressing the second compression spring, and after the inclined plate moves to the top of the conical clamping ring, the second compression spring in a stressed state can push the transmission plate to reset in the opposite direction, thereby forming a clamping relationship between the inclined plate and the conical clamping ring, thereby stably limiting the support tube, and then pushing the moving plate horizontally to adjust the lateral position of the support tube, and the support arm can be rotated and adjusted around the adjusting rod as the center, and after the adjustment is completed, the first plug rod can be released, and the first tension spring in a stressed state can drive the first plug rod to move, so that the first plug rod can pass through the corresponding first plug hole, thereby positioning the moving plate, and thus positioning the support tube; S3.

When the push plate moves upward, the first compression spring can be compressed. Therefore, after the hook and the clamping frame are released, the first compression spring in a stressed state can push the push plate to reset in the opposite direction, thereby clamping the blood vessel. In the clamping process, the blood vessel can be photographed by a camera, and the picture can be transmitted to the display screen. The picture of the blood vessel can be displayed on the display screen to assist in positioning and clamping the blood vessel.

[0016] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

After that, after the lower part of the support tube is inserted into the patient's abdominal cavity, and under the guidance of the display mechanism, after the blood vessel to be blocked is found, the supporting plate and the fixing plate are respectively placed above and below the blood vessel, and then the push plate is pushed upward to drive the moving rod to move upward, and the two arc-shaped clamping pads can be used to clamp the blood vessel to interrupt the blood flow in the blood vessel. After that, the hook is turned over to clamp the hook with the clamping frame, so that the moving rod can be limited to maintain a stable clamping of the blood vessel, and when the push plate moves upward, the first compression spring can be compressed, so after the hook and the clamping frame are released, the first compression spring in a stressed state can push the push plate to reset in the opposite direction, thereby achieving the effect of clamping the blood vessel. In the present invention, by means of the display mechanism, when clamping the blood vessel, the blood vessel can be photographed by a camera, and then the picture can be transmitted to the display screen, that is, the picture of the blood vessel can be displayed on the display screen, so as to assist in positioning and clamping the blood vessel; In the present invention, by setting up a fixing mechanism, after the base plate and the pressure plate are respectively set above and below the table top for supporting the overall device, the pressure plate can be pressed downward, and the table top can be clamped and positioned using two fixed clamping pads, so that the overall device can be supported and positioned, and then the pressure plate can be stably braked under the braking action of the clamping assembly, so that the table top can be stably clamped, thereby achieving stable support for the overall device.

[0018] After the blocking mechanism is inserted into the patient's abdominal cavity, the present invention can clamp a designated area of ​​the blood vessel under the guidance of a video to quickly block the blood in the blood vessel. In addition, when the device is actually used, it can form a stable support for the blocking mechanism and can adjust the position of the blocking mechanism. Therefore, when assisting medical personnel in performing laparoscopic surgery, it can conveniently clamp and block the blood vessel stably. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example 1: Reference Figure 1-Figure 8 A blood vessel blocking device used in conjunction with a laparoscope in this embodiment includes a bottom plate 1, and a bottom tube 2 is firmly installed on one side of the top of the bottom plate 1. A fixing ring 3 is fixed to the top of the bottom tube 2 for stable support. An adjustment rod 4 is slidably connected inside the bottom tube 2, and the top of the adjustment rod 4 passes through the fixing ring 3 and extends upward, and its top is connected to a support arm 5 through a rotating connection. A movable hole is designed on the support arm 5 for installing a subsequent adjustment mechanism.

[0026] like Figure 1 and Figure 5 As shown, the design of the adjustment mechanism is as follows: a limit rod 8 is fixedly installed in the moving hole of the support arm 5. A moving plate 9 is slidably mounted on the limit rod 8, and the moving plate 9 is tightly slidably connected to the inner wall of the moving hole to ensure that the moving plate 9 can move smoothly along the limit rod 8. A docking ring 15 is fixedly connected to the bottom of the moving plate 9, and the bottom of the docking ring 15 extends to the bottom of the support arm 5. A conical snap ring 16 is also fixedly mounted on the docking ring 15, and the conical snap ring 16 is located below the support arm 5 for subsequent connection with the blocking mechanism. The top of the blocking mechanism is designed with a plug-in structure that matches the inner wall of the docking ring 15, which can be firmly inserted into the docking ring 15 and further fixed by the conical snap ring 16.

[0027] In order to position the moving plate 9, a positioning component is installed on the top of the moving plate 9. Figure 1As shown, the positioning assembly includes a support plate 10 fixedly mounted on the top of the moving plate 9, and the top of the support plate 10 extends to the top of the support arm 5. A first plug rod 11 is slidably connected through the support plate 10, and the first plug rod 11 is located above the support arm 5. At the same time, a fixing bar 13 is fixedly mounted on one side of the top of the support arm 5, and a plurality of first plug holes 14 are provided on the fixing bar 13 at equal intervals. The first plug rod 11 can be movably mounted with these first plug holes 14, so as to realize the positioning of the moving plate 9.

[0028] A first tension spring 12 is sleeved on the first plug rod 11, and the two ends of the first tension spring 12 are fixedly connected to one side of the support plate 10 and one end of the first plug rod 11 respectively. When the position of the movable plate 9 needs to be adjusted, the first plug rod 11 can be manually pulled out from the current first socket 14. Then, the movable plate 9 is pushed to move to the desired position along the limit rod 8. Finally, the first plug rod 11 is released, and the first tension spring 12 in a stressed state will drive the first plug rod 11 to move automatically and pass through the corresponding first socket 14, thereby achieving a firm positioning of the movable plate 9.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, the design of the blocking mechanism is used to clamp the blood vessel so that the blood in the blood vessel is interrupted from flowing. It can be securely mounted on the regulating mechanism by cooperation with the docking ring 15 and the tapered clamping ring 16, and its position can be adjusted as required.

[0030] like Figure 3 and Figure 6 As shown, the display mechanism is mounted on the adjusting rod 4, one side of which is connected to the blocking mechanism. The display mechanism is used to take pictures during the process of the blocking mechanism clamping and blocking the blood vessel to ensure that the clamping position is accurate.

[0031] Finally, the fixing mechanism is respectively connected to the bottom tube 2 and the bottom plate 1. When matched with the bottom plate 1, the fixing mechanism can brake and fix the entire device to ensure the stability of the device during the operation.

[0032] like Figure 3 and Figure 4 As shown, the specific implementation of the blocking mechanism. The support tube 17 is designed to be trapezoidal, and openings are provided at the top and bottom thereof so as to be clamped with the docking ring 15. Inside the support tube 17, a moving rod 18 is slidably connected, and the bottom end of the moving rod 18 extends out from the bottom opening of the support tube 17 and is fixedly connected to a support plate 19. At the bottom of one side of the support tube 17, we fixedly install a fixing plate 21, and arc-shaped clamp pads 22 are fixedly installed on the top of the support plate 19 and the bottom of the fixing plate 21. The two arc-shaped clamp pads 22 cooperate with each other to clamp the blood vessel.

[0033] On the inner wall of the top of one side of the support tube 17, we have opened an adjustment hole 20, and a push plate 25 is fixedly connected to the top of the moving rod 18. One side of the push plate 25 extends out of the adjustment hole 20 and extends to the outside of the support tube 17. On the push plate 25, we have fixedly installed a clamping frame 28 located outside the support tube 17. At the same time, on the top of one side of the support tube 17, we have fixedly installed a connecting shaft 29, and a hook 30 is rotatably sleeved on the connecting shaft 29, and this hook 30 can be movably clamped with the clamping frame 28.

[0034] Inside the support tube 17, we also fixedly install a limit plate 26 located above the push plate 25, and a first compression spring 27 is fixedly connected to the bottom of the limit plate 26, and the bottom end of the first compression spring 27 is fixedly connected to the top of the push plate 25. In this way, when we push the push plate 25 upward, the first compression spring 27 will be compressed, and when we release the clamping relationship between the hook 30 and the clamping frame 28, the first compression spring 27 will push the push plate 25 to reset in the reverse direction.

[0035] Next, let's look at the specific implementation of the limit component. Figure 5 As shown, we have installed a limit assembly on the top of both sides of the support tube 17. Each limit assembly includes a support ring 31 fixedly installed on the top of one side of the support tube 17, and a support rod 32 is fixedly installed in the support ring 31. On the support rod 32, we have slidably sleeved a transmission plate 33, and the top of the transmission plate 33 extends above the support ring 31. On the top of one side of the transmission plate 33, we have fixedly installed an inclined plate 34, and a ball 35 is movably embedded in the inclined surface of the inclined plate 34. This ball 35 is in active contact with the conical clamping ring 16.

[0036] On the support rod 32, we also sleeve a second compression spring 36 located on one side of the transmission plate 33, and the two ends of the second compression spring 36 are respectively fixedly connected to the inner wall of one side of the support ring 31 and the bottom of the other side of the transmission plate 33. In this way, when the support tube 17 is inserted into the docking ring 15, the ball 35 will roll along the inclined surface of the conical snap ring 16, push the transmission plate 33 to move to the side away from the support tube 17, and compress the second compression spring 36. When the inclined plate 34 moves to the top of the conical snap ring 16, the second compression spring 36 in a stressed state will push the transmission plate 33 to reset in the opposite direction, so that the inclined plate 34 and the conical snap ring 16 form a clamping relationship, thereby stably limiting the support tube 17.

[0037] Now let’s look at the specific implementation of the display mechanism. Figure 1 , Figure 2 and Figure 6As shown, we have rotatably sleeved a mounting plate 6 on the adjustment rod 4, and two reinforcement rods 7 are symmetrically fixedly installed on the top of the mounting plate 6. The tops of the two reinforcement rods 7 on the side close to each other are fixedly connected to the two sides of the support arm 5 respectively. On one side of the mounting plate 6, we have rotatably connected a support frame 37, and a display screen 38 is installed on the support frame 37. On one side of the fixed plate 21, we have fixedly installed a limiting plate 23, and a camera 24 is fixedly installed on one side of the limiting plate 23. This camera 24 is electrically connected to the display screen 38, so that when clamping the blood vessel, the blood vessel can be photographed by the camera 24, and the picture can be transmitted to the display screen 38 for display, thereby assisting the doctor to position and clamp the blood vessel.

[0038] like Figure 1 and Figure 8 As shown, finally, let's look at the positioning method of the adjustment rod 4. At the top of one side of the fixing ring 3, we have opened a connection port, and a positioning plate 53 is rotatably connected to one side of the fixing ring 3. On one side of the adjustment rod 4, we have opened a slot 51, and an arc-shaped clamping strip 52 is fixedly installed on the inner wall of one side of the slot 51. One side of the positioning plate 53 passes through the connection port and extends into the slot 51. One side of the positioning plate 53 is provided with a plurality of clamping protrusions 54, which can be movably clamped with the arc-shaped clamping strip 52. In this way, after adjusting the position of the adjustment rod 4 to the specified height, we can rotate the positioning plate 53 to move one side of it into the slot 51, and use the clamping protrusions 54 to clamp the arc-shaped clamping strip 52, so as to position the adjustment rod 4. In this way, after moving the support tube 17 into the patient's abdominal cavity, we can limit the height of the support tube 17.

[0039] When using this device, we first insert the support tube 17 into the docking ring 15, and make the two limiting components clamped with the conical clamping ring 16 to position the support tube 17. Then, we insert the lower part of the support tube 17 into the patient's abdominal cavity, and find the blood vessel to be blocked under the guidance of the display mechanism. Next, we place the support plate 19 and the fixing plate 21 above and below the blood vessel respectively, and push the push plate 25 upward to drive the moving rod 18 to move upward, and use two arc-shaped clamping pads 22 to clamp the blood vessel, so that the blood in the blood vessel is interrupted. Finally, we flip the hook 30 to make it clamped with the clamping frame 28, and limit the moving rod 18 to maintain a stable clamping of the blood vessel. When it is necessary to release the clamping of the blood vessel, we only need to flip the hook 30 to release its clamping relationship with the clamping frame 28. At this time, the first compression spring 27 in the stressed state will push the push plate 25 to reset in the opposite direction, thereby releasing the clamping effect on the blood vessel.

[0040] Example 2: Reference Figure 1 and Figure 7This embodiment is based on the first embodiment. Regarding the blood vessel blocking device for use with laparoscope proposed in the first embodiment, the fixing mechanism mainly includes the bottom plate 1, the bottom tube 2, the connecting plate 40, the sliding rod 39, the pressure plate 41, the fixing clamp 42, the clamping assembly and other components.

[0041] like Figure 1 As shown, first, the bottom tube 2 is fixedly sleeved on the connecting plate 40, and two slide bars 39 are symmetrically fixedly installed on the bottom of the connecting plate 40. The bottom ends of the two slide bars 39 are fixedly connected to the top of the bottom plate 1, ensuring a stable connection between the connecting plate 40 and the bottom plate 1. At the same time, the same pressing plate 41 is slidably sleeved on the two slide bars 39, so that the pressing plate 41 can slide up and down on the slide bars 39.

[0042] The bottom tube 2 passes through the connecting plate 40 and is used to connect other components or serve as a supporting part of the blood vessel blocking device. At the bottom of the connecting plate 40 and the top of the bottom plate 1, we have fixedly installed fixed clamp pads 42. The two fixed clamp pads 42 cooperate with each other to clamp and position the table top.

[0043] like Figure 7 As shown, in order to achieve stable braking of the pressure plate 41, a clamping assembly is installed on one side of the connecting plate 40. The clamping assembly includes a slide rail 43 fixedly installed on the top of the pressure plate 41, and two slide plates 44 are symmetrically slidably connected to the slide rail 43. The two slide plates 44 are rotatably connected to the same rotating rod 46, so that the rotating rod 46 can rotate between the two slide plates 44.

[0044] like Figure 7 As shown, on one side of the connecting plate 40, we fixedly install a mounting frame 45, and one end of a rotating rod 46 extends into the mounting frame 45 and is rotatably connected to the inner wall of the mounting frame 45. In this way, when the pressing plate 41 slides up and down, the rotating rod 46 can be driven to rotate in the mounting frame 45.

[0045] At the top of the rotating rod 46, we fixedly install an arc-shaped positioning rod 47, which runs through the mounting frame 45. On the arc-shaped positioning rod 47, we have opened a plurality of second jacks at equal intervals for clamping with the second insertion rod 48.

[0046] like Figure 7 As shown, on the inner wall of one side of the mounting frame 45, we have slidably connected a second plug rod 48. This second plug rod 48 can be movably engaged with a plurality of second plug holes, respectively, for positioning the arc-shaped positioning rod 47. At the same time, on the second plug rod 48, we have sleeved a second tension spring 49 located outside the mounting frame 45. The two ends of this second tension spring 49 are respectively fixedly connected to one side of the mounting frame 45 and the second plug rod 48, for providing a reset force for the second plug rod 48.

[0047] On the slide bar 39, we also sleeve a third compression spring 50 located at the bottom of the connecting plate 40. The top and bottom ends of the third compression spring 50 are fixedly connected to the bottom of the connecting plate 40 and the top of the bottom plate 1 respectively, and are used to provide a reset force for the pressing plate 41.

[0048] When using the device, we first place the base plate 1 above the table top, and then place the pressing plate 41 below the table top. Next, we press the pressing plate 41 downward so that the pressing plate 41 slides downward on the slide bar 39. Under the sliding cooperation of the slide rail 43 and the two slide plates 44, the sliding of the pressing plate 41 will drive the rotating rod 46 to rotate downward. After the two fixed clamping pads 42 clamp and position the table top, we release the second plug rod 48. At this time, the second tension spring 49 in a stressed state will pull the second plug rod 48 to move, so that the second plug rod 48 is clamped with the corresponding second socket. In this way, the arc-shaped positioning rod 47 can be positioned, and the rotating rod 46 can be further positioned, so that the pressing plate 41 can be stably limited.

[0049] In this way, we can achieve stable support and positioning of the entire device. Then, we can perform the subsequent blood vessel blocking operation. After completing the operation, we only need to pull the second insertion rod 48 to disengage the second insertion hole from the clamping relationship, and then use the reset force of the third compression spring 50 to push the pressing plate 41 to slide upward and reset.

[0050] The present invention provides a method for using a blood vessel blocking device used in conjunction with a laparoscope, comprising the following steps: S1. After the bottom plate 1 and the pressure plate 41 are respectively arranged above and below the table for supporting the whole device, the pressure plate 41 can be pressed downward, and the table can be clamped and positioned by the two fixed clamping pads 42, so that the whole device can be supported and positioned. When the pressure plate 41 moves downward, the sliding cooperation of the slide rail 43 and the two slide plates 44 can drive the rotating rod 46 to rotate downward, and after the table is clamped and positioned, the second plug rod 48 can be released at this time, and the second tension spring 49 in a stressed state can pull the second plug rod 48 to move, so that the second plug rod 48 is clamped with the corresponding second plug hole, so that the arc-shaped positioning rod 47 can be positioned, and the rotating rod 46 can be further positioned, so that the pressure plate 41 can be stably limited; S2, when the support tube 17 is inserted into the docking ring 15, the ball 35 can roll along the inclined surface of the tapered snap ring 16, and at this time, the transmission plate 33 can be pushed to move to the side away from the support tube 17, and the second compression spring 36 can be compressed, and after the inclined plate 34 moves to the top of the tapered snap ring 16, the second compression spring 36 in the stressed state can push the transmission plate 33 to reset in the opposite direction, so that the inclined plate 34 and the tapered snap ring 16 form a clamping relationship, and the support tube 17 can be stably limited, and then the movable plate 9 is pushed horizontally to adjust the horizontal position of the support tube 17, and the support arm 5 can be rotated and adjusted around the adjustment rod 4. After the adjustment is completed, the first insertion rod 11 can be released, and the first tension spring 12 in the stressed state can drive the first insertion rod 11 to move, so that the first insertion rod 11 can pass through the corresponding first insertion hole 14, so that the movable plate 9 can be positioned, and the support tube 17 can be positioned; S3. The support tube 17 is inserted into the abdominal cavity of the patient by respectively pushing the support arm 5 longitudinally and rotating the support arm 5. After the support tube 17 is inserted into the abdominal cavity of the patient, the positioning plate 53 can be rotated to move one side of the positioning plate 53 into the clamping groove 51, and the arc-shaped clamping strip 52 is clamped by the clamping protrusion 54, so that the adjustment rod 4 can be positioned, that is, after the support tube 17 is moved into the abdominal cavity of the patient, the height of the support tube 17 can be limited; S4. Push the push plate 25 upward to drive the moving rod 18 to move upward, and the two arc-shaped clamping pads 22 can be used to clamp the blood vessel to interrupt the blood flow in the blood vessel. Then, by flipping the hook 30, the hook 30 and the clamping frame 28 are clamped together, so that the moving rod 18 can be limited to maintain a stable clamping of the blood vessel, and when the push plate 25 moves upward, the first compression spring 27 can be compressed, so after the hook 30 and the clamping frame 28 are released, the first compression spring 27 in a stressed state can push the push plate 25 to reset in the opposite direction, and the contact has an effect of clamping the blood vessel, and during the clamping process, the camera 24 can be used to shoot the blood vessel, and then the picture can be transmitted to the display screen 38, and the display screen 38 can be used to display the picture of the blood vessel, so as to assist in positioning and clamping the blood vessel.

[0051] However, as is well known to those skilled in the art, the working principles and wiring methods of the camera 24 and the display screen 38 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention; the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.

10. A method for using a blood vessel blocking device used in conjunction with a laparoscope, applied to the blood vessel blocking device used in conjunction with a laparoscope as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: S1. After the bottom plate (1) and the pressure plate (41) are respectively arranged above and below the table for supporting the whole device, the pressure plate (41) can be pressed downward, and the table can be clamped and positioned by using two fixed clamping pads (42), so that the whole device can be supported and positioned. When the pressure plate (41) moves downward, the sliding cooperation of the slide rail (43) and the two slide plates (44) can drive the rotating rod (46) to rotate downward. After the table is clamped and positioned, the second insertion rod (48) can be released, and the second tension spring (49) in a stressed state can pull the second insertion rod (48) to move, so that the second insertion rod (48) is clamped with the corresponding second insertion hole, so that the arc-shaped positioning rod (47) can be positioned, and the rotating rod (46) can be further positioned, so that the pressure plate (41) can be stably limited. S2. When the support tube (17) is inserted into the docking ring (15), the ball (35) can roll along the inclined surface of the conical snap ring (16), thereby pushing the transmission plate (33) to move to the side away from the support tube (17), thereby compressing the second compression spring (36). After the inclined plate (34) moves to the top of the conical snap ring (16), the second compression spring (36) in a stressed state can push the transmission plate (33) to reset in the reverse direction, thereby forming a clamping relationship between the inclined plate (34) and the conical snap ring (16). The support tube (17) can be stably limited, and then the movable plate (9) can be pushed laterally to adjust the lateral position of the support tube (17), and the support arm (5) can be rotated and adjusted around the adjustment rod (4). After the adjustment is completed, the first insertion rod (11) can be released, and the first tension spring (12) in a stressed state can drive the first insertion rod (11) to move, so that the first insertion rod (11) can pass through the corresponding first insertion hole (14), so that the movable plate (9) can be positioned, and the support tube (17) can be positioned; S3, by respectively pushing the support arm (5) longitudinally and rotating the support arm (5), the support tube (17) is inserted into the abdominal cavity of the patient. After the support tube (17) is inserted into the abdominal cavity of the patient, the positioning plate (53) can be rotated to move one side of the positioning plate (53) into the clamping groove (51), and the arc-shaped clamping strip (52) is clamped by the clamping protrusion (54), so that the adjustment rod (4) can be positioned, that is, after the support tube (17) is moved into the abdominal cavity of the patient, the height of the support tube (17) can be limited; S4. Push the push plate (25) upward to drive the moving rod (18) to move upward, and then use the two arc-shaped clamping pads (22) to clamp the blood vessel, so that the blood flow in the blood vessel is interrupted. Then, by turning the hook (30), the hook (30) and the clamping frame (28) are clamped together, so that the moving rod (18) can be limited and the blood vessel can be stably clamped. When the push plate (25) moves upward, the first compression spring (27) can be compressed. Therefore, after the hook (30) and the clamping frame (28) are released from the clamping, the first compression spring (27) in a stressed state can push the push plate (25) to reset in the opposite direction, thereby achieving the effect of clamping the blood vessel. In the clamping process, the camera (24) can be used to shoot the blood vessel, and then the picture can be transmitted to the display screen (38). The picture of the blood vessel can be displayed on the display screen (38) to assist in positioning and clamping the blood vessel.
