Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and more specifically, to a vascular traction device and medical equipment. Background Technology
[0002] During laparoscopic surgery, depending on the surgical site, when cutting or dissecting certain tissues or organs, it is necessary to pull the surrounding blood vessels to expose the field of vision required for the surgical operation.
[0003] Current techniques for vascular traction are primarily achieved by creating a perforation in the abdominal cavity and then using surgical forceps or other instruments to assist in traction of the blood vessel. While this method is convenient, it causes some damage to the body because it requires creating an additional perforation in the abdominal wall. Utility Model Content
[0004] The purpose of this application is to provide a vascular traction device and medical equipment that can provide stable and reliable traction for blood vessels without the need for additional penetration holes, thereby reducing the workload of doctors and minimizing damage to patients.
[0005] The embodiments of this application are implemented as follows:
[0006] A first aspect of this application provides a vascular traction device, including a housing and a traction portion and a suction portion respectively disposed at opposite ends of the housing. The suction portion is fixed against the fixed end of the traction portion, and the active end of the traction portion, opposite to the fixed end, extends outside the housing. The suction portion is driven to move relative to the housing, thereby causing the traction portion to move relative to the housing, thus adjusting the actual extension length of the active end of the traction portion. The active end of the traction portion is used to traction a blood vessel, and the suction portion is used to drive the blood vessel to move under magnetic influence through the traction portion. This vascular traction device can provide stable and reliable traction for blood vessels without the need for additional penetration holes, reducing the workload of doctors and minimizing damage to patients.
[0007] In one possible implementation, the suction unit includes a housing, a pusher and a magnetic component disposed within the housing, wherein the pusher is abutted and fixed to the fixed end of the pulling unit, and the magnetic component is magnetically connected to a magnetic supply device in the external environment.
[0008] As one possible implementation, the housing is provided with a gripping structure, which is used to drive the suction part to move relative to the outer shell toward the side away from the pulling part under the pulling action.
[0009] In one possible implementation, a connector is provided between the fixed end and the working end of the pulling part, and a through hole is provided on the outer shell. The connector passes through the through hole to guide the movement of the pulling part relative to the outer shell.
[0010] In one possible implementation, a sealed space is formed between the outer shell, the suction part, and the fixed end of the pulling part. An elastic element is provided in the sealed space, and the opposite ends of the elastic element are respectively connected to the fixed ends of the suction part and the pulling part. The elastic element is in a compressed state.
[0011] As one possible implementation, the elastic element includes a spring or a sheet spring.
[0012] As one possible implementation, the working end of the pulling part is hook-shaped.
[0013] As one possible implementation, a plurality of first limiting portions are provided at intervals on the inner wall of the outer shell along the extending direction of the outer shell, and a second limiting portion is provided on the outer wall of the fixed end of the pulling portion. The second limiting portion engages with any one of the first limiting portions to lock the fixed end of the pulling portion to the outer shell.
[0014] In one possible implementation, the first limiting part is a groove, and the second limiting part is a protrusion corresponding to the groove; or, the first limiting part is a protrusion, and the second limiting part is a groove corresponding to the protrusion.
[0015] A second aspect of this application provides a medical device including a stent, a magnetic supply device disposed on the stent, and the aforementioned vascular traction device, wherein the magnetic supply device is magnetically connected to the attraction portion of the vascular traction device. This vascular traction device can provide stable and reliable traction to blood vessels without requiring additional penetration holes, reducing the workload of doctors and minimizing damage to patients.
[0016] The beneficial effects of the embodiments of this application include:
[0017] This vascular traction device includes a housing and a traction section and a suction section respectively disposed at opposite ends of the housing. The suction section is fixed against the fixed end of the traction section, and the active end of the traction section, opposite to the fixed end, extends outside the housing. The suction section is driven to move relative to the housing, thereby causing the traction section to move relative to the housing, thus adjusting the actual extension length of the active end of the traction section. The active end of the traction section is used to traction the blood vessel, and the suction section is used to drive the blood vessel to move under magnetic influence through the traction section. Compared with the prior art, the vascular traction device provided in this application can precisely traction the blood vessel by coordinating the traction section and the suction section and adjusting the actual extension length of the active end of the traction section accordingly. Furthermore, by coordinating the suction section and the magnetic supply device, it avoids adding unnecessary penetration holes in the human body, reducing surgical trauma, lowering the risk of infection, and facilitating postoperative recovery for patients. Since the magnetic traction method between the suction section and the magnetic supply device has the advantages of stability and reliability, it can stably and reliably traction the blood vessel without requiring the doctor to manipulate the blood vessel with instruments. The doctor only needs to control the magnetic supply device to achieve the purpose of surgical field exposure, thereby reducing the workload of the doctor. Attached Figure Description

[0029] Please refer to the reference. Figures 1 to 3This application provides a vascular traction device 100, including a housing 10 and a traction portion 20 and a suction portion 30 respectively disposed at opposite ends of the housing 10. The suction portion 30 is fixed against the fixed end 21 of the traction portion 20, and the active end 22 of the traction portion 20, opposite to the fixed end 21, extends out of the housing 10. The suction portion 30 is driven to move relative to the housing 10, thereby driving the traction portion 20 to move relative to the housing 10, thus adjusting the actual extension length of the active end 22 of the traction portion 20. The active end 22 of the traction portion 20 is used to traction a blood vessel 300, and the suction portion 30 is used to drive the blood vessel 300 to move under magnetic action through the traction portion 20. This vascular traction device 100 can provide stable and reliable traction for the blood vessel 300 without the need for additional penetration holes, reducing the workload of doctors and mitigating damage to patients.
[0030] It should be noted that, as Figure 1 and Figure 2 As shown, the vascular traction device 100 includes a housing 10, a traction section 20, and a suction section 30. Along the extending direction of the housing 10, the traction section 20 and the suction section 30 are respectively disposed at opposite ends of the housing 10, so that the housing 10 provides support and protection for the traction section 20 and the suction section 30. The traction section 20 has a fixed end 21 and an actuating end 22 disposed opposite to each other. The suction section 30 is fixed against the fixed end 21 of the traction section 20, so that the movement of the suction section 30 can be transmitted to the fixed end 21 of the traction section 20, thereby enabling the traction section 20 to generate corresponding movement. Simultaneously, the actuating end 22 of the traction section 20 extends outside the housing 10, so that it directly contacts the blood vessel 300, thereby enabling the vascular traction device 100 to perform a traction operation on the blood vessel 300.
[0031] like Figure 1 As shown, in the initial state, the actual extension length of the working end 22 of the traction part 20 is relatively small to ensure that the vascular traction device 100 can smoothly reach the patient's lesion under the action of the special grasping forceps. Then, as... Figure 2 As shown, under the action of external force (e.g., engaging grippers), the suction part 30 is driven to move relative to the outer shell 10, which in turn drives the pulling part 20 to move relative to the outer shell 10. This adjusts the actual extension length of the working end 22 of the pulling part 20 accordingly, for example, by increasing or decreasing the actual extension length of the working end 22 of the pulling part 20, so that it can contact the blood vessel 300 and pull the blood vessel 300.
[0032] The actual extension length of the working end 22 of the aforementioned traction part 20, that is, the actual length of the portion of the working end 22 of the traction part 20 extending outside the outer shell 10, can be adjusted by moving the traction part 20 relative to the outer shell 10, thereby adjusting the actual position of the traction part 20 relative to the outer shell 10. In this way, the vascular traction device 100 provided in this application can be adapted to different surgical scenarios and the actual conditions such as the position and size of the blood vessel 300. For example, when the blood vessel 300 is far away, the suction part 30 can be controlled to move the traction part 20 towards the side away from the suction part 30, thereby increasing the actual extension length of the working end 22 of the traction part 20; when the blood vessel 300 is close, the suction part 30 can be controlled to move the traction part 20 towards the side closer to the suction part 30, thereby decreasing the actual extension length of the working end 22 of the traction part 20.
[0033] like Figure 1 and Figure 2 As shown, the suction part 30 is also magnetic, so that the suction part 30 can drive the blood vessel 300 to move under the action of magnetism through the traction part 20. In this way, as... Figure 3 As shown, during the surgery, there is no need to add extra penetration holes to the human body. Only through the magnetic supply device in the external environment, the traction device of the blood vessel 300, which has been magnetically connected to the blood vessel 300 through the human body (such as the abdominal wall 200), can be magnetically connected. Under the magnetic traction of the magnetic supply device, the suction part 30 of the blood vessel 300 traction device can be moved, thereby moving the blood vessel 300 through the traction part 20 of the blood vessel 300 traction device to expose the field of vision required for the surgical operation.
[0034] Compared to existing technologies, the vascular traction device 100 provided in this application, through the coordinated work of the traction part 20 and the suction part 30, can precisely traction the blood vessel 300 by adjusting the actual extension length of the working end 22 of the traction part 20 accordingly. Furthermore, through the coordinated work of the suction part 30 and the magnetic supply device, it avoids adding unnecessary penetration holes to the human body, reducing surgical trauma, lowering the risk of infection, and facilitating postoperative recovery for the patient. Since the magnetic traction method between the suction part 30 and the magnetic supply device has the advantages of stability and reliability, it can stably and reliably traction the blood vessel 300 without requiring the doctor to manipulate the blood vessel 300 with instruments; the doctor only needs to control the magnetic supply device to achieve surgical field exposure, thereby reducing the doctor's workload.
[0035] As one possible implementation method, such as Figure 1 and Figure 2As shown, the suction part 30 includes a housing 31, and a pusher 32 and a magnetic member 33 disposed in the housing 31. The pusher 32 is abutted and fixed to the fixed end 21 of the pulling part 20, and the magnetic member 33 is magnetically connected to a magnetic supply device in the external environment.
[0036] It should be noted that, as Figure 1 and Figure 2 As shown, the suction part 30 includes a housing 31, a pusher 32, and a magnetic component 33. The pusher 32 is located on the side closer to the pulling part 20 and is fixed against the fixed end 21 of the pulling part 20. The pusher 32 transmits the movement of the suction part 30 relative to the housing 10 to the pulling part 20, thereby adjusting the actual extension length of the working end 22 of the pulling part 20 accordingly. The magnetic component 33 is located on the side away from the pulling part 20 so that the magnetic component 33 can be magnetically connected to the magnetic supply device in the external environment by magnetic attraction.
[0037] When it is necessary to increase the actual extension length of the working end 22 of the pulling part 20, it is only necessary to apply a pressing action to the end of the suction part 30 away from the pulling part 20, so that the suction part 30 moves toward the side closer to the pulling part 20; while when it is necessary to decrease the actual extension length of the working end 22 of the pulling part 20, in order to facilitate applying a pulling action to the end of the suction part 30 away from the pulling part 20, as an implementation method, such as Figure 1 and Figure 2 As shown, a gripping structure 311 is provided on the housing 31. The gripping structure 311 is used to drive the suction part 30 relative to the outer shell 10 toward the side away from the pulling part 20 under the pulling action, so as to avoid the instrument from sliding or even slipping off the suction part 30 when the suction part 30 is pulled. For example, the gripping structure 311 may be a fixing groove formed on the housing 31, or it may be a fixing ring formed on the housing 31, so as to facilitate the connection of the instrument applying the pulling action.
[0038] As one possible implementation method, such as Figure 1 and Figure 2 As shown, a connector 23 is provided between the fixed end 21 and the working end 22 of the traction part 20. A through hole is provided on the outer shell 10, and the connector 23 passes through the through hole to guide the movement of the traction part 20 relative to the outer shell 10, thereby ensuring that the working end 22 of the traction part 20 can smoothly pull the blood vessel 300.
[0039] As one possible implementation method, such as Figure 1 and Figure 2As shown, a sealed space 40 is formed between the outer shell 10, the suction part 30, and the fixed end 21 of the pulling part 20. An elastic element 41 is disposed within this sealed space 40 to prevent interference from the internal environment and to provide a buffering effect. The opposite ends of the elastic element 41 are connected to the fixed end 21 of the suction part 30 and the pulling part 20, respectively, and the elastic element 41 is in a compressed state. As one possible implementation, the elastic element 41 can include a spring or a sheet spring, as long as it can provide elastic potential energy.
[0040] During the procedure, the traction force on the blood vessel 300 needs to maintain a certain level of reliability and stability. When the suction unit 30 is driven to pull the blood vessel 300 through the traction unit 20, the elastic element 41 can adjust the magnitude of the pulling force according to the actual situation. If the pulling force suddenly increases, the elastic element 41 can alleviate this sudden change by appropriately stretching, avoiding damage to the blood vessel 300 due to excessive pulling force; conversely, if the pulling force suddenly decreases, the compressed state of the elastic element 41 can ensure that there is still a certain pulling force acting on the blood vessel 300 to maintain the traction state of the blood vessel 300.
[0041] As one possible implementation, the working end 22 of the pulling part 20 is hook-shaped. For example, such as... Figure 1 and Figure 2 As shown, in this embodiment, the hook-shaped structure of the working end 22 of the traction part 20 has only a small notch to ensure that the blood vessel 300 can enter the interior of the hook-shaped structure through the notch. Under the magnetic traction of the magnetic supply device, it is not easy for the blood vessel 300 to fall off from the interior of the hook-shaped structure through the notch.
[0042] As one possible implementation method, such as Figure 1 and Figure 2 As shown, along the extending direction of the outer casing 10, a plurality of first limiting portions 11 are spaced apart on the inner wall of the outer casing 10, and a second limiting portion 211 is provided on the outer wall of the fixed end 21 of the traction portion 20. The second limiting portion 211 engages with any one of the first limiting portions 11 to lock the fixed end 21 of the traction portion 20 to the outer casing 10. In this way, when the second limiting portion 211 engages with any one of the first limiting portions 11, the fixed end 21 of the traction portion 20 is locked to the outer casing 10. At this time, the actual extension length of the working end 22 of the traction portion 20 can remain unchanged, thereby ensuring that the traction effect of the traction portion 20 on the blood vessel 300 is more stable and reliable. For example, as... Figure 1 and Figure 2As shown, in this embodiment, there are three first limiting parts 11. In the initial state, the second limiting part 211 is engaged with the first limiting part 11 on the side near the suction part 30. When it is necessary to adjust the actual extension length of the working end 22 of the pulling part 20, the second limiting part 211 can selectively engage with the other two first limiting parts 11. After the adjustment is in place, the second limiting part 211 no longer moves, but remains in the current position.
[0043] As one possible implementation method, such as Figure 1 and Figure 2 As shown, the first limiting part 11 is a groove, and the second limiting part 211 is a protrusion corresponding to the groove; or, the first limiting part 11 is a protrusion, and the second limiting part 211 is a groove corresponding to the protrusion. Those skilled in the art should be able to make reasonable choices and designs based on actual conditions. No specific limitations are imposed here, as long as the fixed end 21 of the pulling part 20 and the outer shell 10 can be locked when the second limiting part 211 is engaged with any one of the first limiting parts 11, and the fixed end 21 of the pulling part 20 and the outer shell 10 can be released when the second limiting part 211 is separated from any one of the first limiting parts 11.
[0044] This application also provides a medical device, including a support, a magnetic supply device disposed on the support, and the aforementioned vascular traction device 100. The magnetic supply device is magnetically connected to the attraction portion 30 of the vascular traction device 100. For example, the medical device further includes a robotic arm, with a support disposed on the robotic arm, so that the magnetic supply device is connected to the robotic arm via the support, thereby enabling the robotic arm to drive relative movement of the magnetic supply device, thus exerting a traction effect on the blood vessels 300 within the human body. Since the structure and beneficial effects of the vascular traction device 100 have been described in detail in the foregoing embodiments, they will not be repeated here.
[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
