Description

Technical Field

[0001] The present invention relates to the technical field of interventional treatment instruments, and in particular to a vascular surgery interventional fixation device. Background Art

[0002] In modern medical practice, vascular surgery intervention is widely used in the treatment of various diseases due to its advantages of less trauma and quick recovery. This type of surgery usually involves the use of a puncture needle or other slender instruments through the skin to enter the blood vessels for the purpose of diagnosis or treatment. In order to ensure the success of the operation, accuracy and stability during the puncture process are crucial.

[0003] However, the existing puncture technology still has some shortcomings in practical application. The traditional puncture method usually relies on the doctor's manual operation to adjust the position and angle of the puncture needle by continuous rotation to find the best puncture path. Although this rotation method can achieve adjustment to a certain extent, since the entire device is fixed on the human body, repeated rotation may cause discomfort to the patient and even cause local tissue damage.

[0004] In addition, the existing interventional fixation devices are relatively simple in design and difficult to adapt to puncture needles of different models and specifications. This means that when facing different surgical needs, medical staff may need to frequently change different fixation devices, which not only prolongs the surgical preparation time, but may also cause unnecessary interruptions during the operation, affecting the efficiency and safety of the operation. Summary of the invention

[0025] As a preferred solution of the present invention, limiting members are provided on both sides of the track.

[0026] As a preferred solution of the present invention, the limiting member is a bolt.

[0027] As a preferred solution of the present invention, the control component 2 includes:

[0028] The second handle is fixed on another rotating rod, and the second handle is rotatably mounted on one end of the second operating handle through the second hinge seat;

[0029] A second slide bar slides on the slide plate, and a second elastic member is sleeved on the second slide bar;

[0030] The second clamping block is fixed to the bottom end of the second slide bar; the two ends of the second elastic member are respectively in contact with the sliding plate and the support plate; when the position of the sliding plate is fixed, the second clamping block is in close contact with the support plate;

[0031] The second transmission member has one end connected to one end of the second operating handle and the other end connected to the second slide bar.

[0032] As a preferred solution of the present invention, the bottoms of the first pressing block and the second pressing block are both provided with anti-slip coatings.

[0033] As a preferred solution of the present invention, a plurality of annular anti-slip protrusions are arranged side by side on both handle 1 and handle 2.

[0034] As a preferred embodiment of the present invention, it also includes:

[0035] The mobile frame is door-shaped and is mounted on the fixed frame by longitudinal sliding;

[0036] A moving mechanism is arranged on the fixed frame and is used to drive the moving frame to slide;

[0037] The clamping assembly is arranged on the movable frame and is used for fixing the syringe.

[0038] As a preferred solution of the present invention, the moving mechanism includes:

[0042] As a preferred solution of the present invention, the clamping assembly comprises:

[0043] A bottom plate is fixed to the bottom end of the movable frame, and the bottom plate contacts the bottom of the syringe;

[0044] Screw rod 2, threadedly connected to the moving frame;

[0045] The top plate is located above the bottom plate, the top plate is rotatably connected to the second screw rod, and an optical axis 1 slidably connected to the moving frame is fixed to the top plate.

[0049] Compared with the prior art, the beneficial effects of the present invention are as follows: when in use, the support plate is first placed on the patient's body, and then the support plate is firmly fixed using the locking member, and then the syringe is fixed on the fixing frame. When the angle of the syringe needs to be adjusted, one hand holds the control component 2, and the other hand holds the handle 1 of the control component 1, and the operating handle 1 is pressed to rotate the operating handle 1 around the hinge seat 1, thereby driving the transmission member 1 to move. Since the transmission member 1 connects the operating handle 1 and the slide rod 1, the slide rod 1 and the clamping block 1 both move upward, so that the clamping block 1 is separated from the fixed shaft. At this time, the rotating rod, the fixing frame and the syringe can rotate around the fixed shaft. The axis rotates, and during the rotation process, the other end of the rotating rod slides along the bracket, which improves the stability of the adjustment process. When it is adjusted to a suitable angle, release the operating handle one, and under the elastic force of the elastic member one, the clamping block one drops and contacts the fixed axis again, and the operating handle one also returns to its initial state, so that the angles of the rotating rod, the fixed frame and the syringe are fixed, and then the position of the syringe can be adjusted through the control component two. The principle of the control component two is roughly the same as that of the control component one. Compared with the method of adjusting the angle and position by continuous rotation in the prior art, it will not cause a burden on the patient's body and reduce the patient's discomfort.

[0057] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0058] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0059] Secondly, the term "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0060] Example

[0061] Reference Figure 1-Figure 5 This embodiment provides a vascular surgical intervention fixation device, including:

[0062] A support plate 1 is used to carry other components, and a through hole 2 is provided in the middle thereof for the puncture needle to pass through;

[0063] The locking member 3 is fixed on the bottom surface of the support plate 1 and is used to fix the support plate 1 on the patient's body. The locking member 3 can be a Velcro or a buckle, and the tightness can be freely adjusted to suit the patient;

[0064] There are two adjusting components 4, which are respectively arranged on both sides of the through hole 2;

[0065] like Figure 3As shown, the fixing frame 5 is door-shaped and is used to fix the syringe, the puncture needle is fixed at the bottom end of the syringe, and the fixing frame 5 is installed on the output ends of the two adjustment components 4;

[0066] The adjustment component 4 comprises:

[0067] The track 41 is fixed to the top of the support plate 1 along the length direction of the through hole 2;

[0068] A sliding plate 42 is slidably connected to the track 41, and a fixed shaft 43 is fixed to the sliding plate 42;

[0069] The bracket 44 is fixed on the sliding plate 42 and is semicircular in shape, and the bracket 44 is coaxial with the fixed shaft 43;

[0070] A rotating rod 45, one end of which is rotatably connected to the fixed shaft 43, and the other end of which slides along the bracket 44, so that the rotating rod 45 can rotate around the fixed shaft 43;

[0071] The fixing frame 5 is fixed to the other end of the two rotating rods 45, so that the fixing frame 5, the syringe, etc. can rotate around the fixed axis 43;

[0072] Also includes:

[0073] A control assembly 6, disposed on a rotating rod 45, for controlling the angle of the syringe;

[0074] like Figure 2 and Figure 4 As shown, the control component 16 includes:

[0075] A handle 61 is fixed on a rotating rod 45. The handle 61 is rotatably mounted with one end of an operating handle 63 through a hinge seat 62. The operating handle 63 is located at the bottom end of the handle 61.

[0076] A slide bar 64 slides on the rotating bar 45, and an elastic member 65 is mounted on the slide bar 64, and the elastic member 65 is a spring;

[0077] The clamping block 66 is fixed to the bottom end of the slide rod 64; the two ends of the elastic member 65 are respectively in contact with the rotating rod 45 and the clamping block 66; when the angle of the rotating rod 45 is fixed, the clamping block 66 is in close contact with the fixed shaft 43. In order to increase the contact area, the side of the clamping block 66 in close contact with the fixed shaft 43 is set to be an arc shape;

[0078] A transmission member 67, one end of which is connected to one end of an operating handle 63, and the other end of which is connected to a slide bar 64. The transmission member 67 is made of a steel wire rope or a nylon rope;

[0079] It also includes: a control assembly 2 7, which is arranged on another rotating rod 45 and is used to control the position of the syringe;

[0080] The specific working process of the device is as follows: when in use, first place the support plate 1 on the patient's body, then use the locking member 3 to firmly fix the support plate 1, and then fix the syringe on the fixing frame 5. When the angle of the syringe needs to be adjusted, hold the control component 27 with one hand, hold the handle 61 of the control component 6 with the other hand, and press the operating handle 63 to rotate the operating handle 63 around the hinge seat 62 to approach the handle 61, thereby driving the transmission member 67 to move. Since the transmission member 67 connects the operating handle 63 and the slide bar 64, the slide bar 64 and the clamping block 66 all move upward, so that the clamping block 66 is separated from the fixed shaft 43. At this time, the rotating rod 45, the fixing frame 5 and the needle The syringe can rotate around the fixed axis 43. During the rotation, the other end of the rotating rod 45 slides along the bracket 44, which improves the stability of the adjustment process. When it is adjusted to a suitable angle, the operating handle 63 is released. Under the elastic force of the elastic member 65, the clamping block 66 descends and contacts the fixed axis 43 again. The operating handle 63 also returns to its initial state, so that the angles of the rotating rod 45, the fixed frame 5 and the syringe are fixed. Then, the position of the syringe can be adjusted through the control component 27. The principle of the control component 27 is roughly the same as that of the control component 16. Compared with the method of adjusting the angle and position by continuous rotation in the prior art, it will not cause a burden on the patient's body and reduce the patient's discomfort.

[0081] If the stopper 8 is not provided, the sliding plate 42 may be deviated from the track 41, which may cause the operation to be interrupted suddenly, and the doctor needs to stop and readjust or repair the device, which prolongs the operation time. The present invention makes the following improvements, such as Figure 1 As shown, limit members 8 are provided on both sides of the track 41. The limit members 8 form physical barriers on both sides of the track 41, which effectively prevent the sliding plate 42 from leaving the track 41 during the sliding process. The doctor can operate the device more confidently without worrying about the risk of the sliding plate 42 leaving the track 41, and the operation is simpler and more intuitive.

[0082] If the stopper 8 is fixedly connected to the track 41, it will be difficult to separate the sliding plate 42 from the track 41, and the device will be inconvenient to repair. Figure 1 As shown, the limit member 8 is a bolt, and the bolt as the limit member 8 can be tightened or loosened at any time. When cleaning or replacement of parts is required, the limit member 8 can be easily removed, which is convenient for maintenance.

[0083] The control component 1 6 and the control component 2 7 are respectively arranged on both sides of the fixed frame 5. When the position or angle of the syringe needs to be adjusted, the control component 1 6 and the control component 2 7 are respectively operated by two hands, which is more convenient to adjust the position and angle of the syringe, and the adjustment is also more smooth. Figure 1-Figure 3 and Figure 5 As shown, as a preferred solution of the present invention, the control component 2 7 includes:

[0084] The second handle 71 is fixed on another rotating rod 45, and the second handle 71 is rotatably mounted on one end of the second operating handle 73 through the second hinge seat 72;

[0085] A second slide bar 74 slides on the slide plate 42, and a second elastic member 75 is mounted on the second slide bar 74;

[0086] The second clamping block 76 is fixed to the bottom end of the second slide bar 74; the two ends of the second elastic member 75 are respectively in contact with the sliding plate 42 and the support plate 1, and the second elastic member 75 is a spring; when the position of the sliding plate 42 is fixed, the second clamping block 76 is in close contact with the support plate 1;

[0087] The second transmission member 77 has one end connected to one end of the operating handle and the other end connected to the second slide bar 74. The second transmission member 77 adopts a steel wire rope or a nylon rope. In order to prevent the position of the second pressing block 76 from being affected when the syringe angle is adjusted, when the second pressing block 76 contacts the support plate 1, the second transmission member 77 is in a relatively loose state, and will not affect the state of the second pressing block 76 when the angle is adjusted, so that the position of the sliding plate 42 remains unchanged;

[0088] The specific working process of control component 27 is as follows: when it is necessary to adjust the position of the fixed frame 5 and the syringe, hold the handle 2 71 and press the operating handle 2 73 to rotate the operating handle 2 73 around the hinge seat 2 72 toward the handle 2 71, the transmission member 2 77 is gradually tightened to drive the slide rod 2 74 and the clamping block 2 76 to move upward, and the elastic member 2 75 is compressed. When the clamping block 2 76 is separated from the support plate 1, hold the handle 1 61 and the handle 2 71 to move the sliding plate 42 along the track 41, thereby adjusting the position of the fixed frame 5 and the syringe. In this process, the relative position of the clamping block 1 66 and the fixed shaft 43 remains unchanged, so the fixed frame 5 and the syringe maintain an unchanged angle; after the position adjustment is completed, release the operating handle 2 73, and under the elastic force of the elastic member 2 75, the clamping block 2 76 contacts the support plate 1 again to fix the position of the fixed frame 5 and the syringe;

[0089] It should be noted that control component 1 6 and control component 2 7 can be used simultaneously or one of them can be used alone, and neither will affect the other.

[0090] Without the anti-slip coating, the clamping block 1 66 and the clamping block 2 76 are prone to slip when contacting the fixed shaft 43 or the surface of the support plate 1, which will cause instability of the rotating rod 45 and the fixing frame 5 at the set angle and position. As a preferred embodiment of the present invention, the bottom of the clamping block 1 66 and the clamping block 2 76 are provided with an anti-slip coating. The anti-slip coating can significantly increase the friction between the clamping block 1 66 and the fixed shaft 43 or the clamping block 2 76 and the surface of the support plate 1, prevent relative sliding, and ensure the stability of the device.

[0091] The smooth handle surface can easily cause the hands to slip. As a preferred embodiment of the present invention, multiple annular anti-skid protrusions are arranged side by side on handle 1 61 and handle 2 71. The annular anti-skid protrusions increase the friction of the handle surface to prevent the hands from slipping, ensuring that the doctor can hold the handles firmly during the operation.

[0092] After adjusting the angle and position of the syringe, the distance between the puncture needle and the body may be too large, which may make the puncture needle unusable. As a preferred embodiment of the present invention, Figure 1 and Figure 3 As shown, it also includes:

[0093] The movable frame 9 is door-shaped and longitudinally slidably mounted on the fixed frame 5;

[0094] The moving mechanism 10 is arranged on the fixed frame 5 and is used to drive the moving frame 9 to slide;

[0095] A clamping assembly 11, disposed on the mobile frame 9, for fixing the syringe;

[0096] When in use, fix the syringe on the clamping assembly 11, and then operate the moving mechanism 10 to move the moving frame 9, the clamping assembly 11 and the syringe at the same time, so that the distance between the puncture needle and the body can be adjusted. After adjusting to the optimal distance, puncture is performed, which improves the convenience of use.

[0097] As a preferred embodiment of the present invention, Figure 3 and Figure 4 As shown, the moving mechanism 10 comprises:

[0098] The screw sleeve 101 is fixedly connected to the movable frame 9;

[0099] The screw rod 102 is rotatably mounted on the fixing frame 5, and the screw rod 102 is threadedly connected with the screw sleeve 101;

[0100] The power mechanism 103 is fixed on the fixed frame 5. The power mechanism 103 adopts a servo motor. The output end of the power mechanism 103 is connected to the screw rod 102 by transmission. The power mechanism 103 is connected to the screw rod 102 by transmission through a synchronous belt or a chain.

[0101] The specific working process of the moving mechanism 10 is as follows: after the power mechanism 103 is turned on, the power is transmitted to the screw 102 through a synchronous belt or chain, the screw 102 rotates, and the rotational motion is converted into the linear motion of the screw sleeve 101 through a threaded connection, and the moving frame 9 slides longitudinally along the fixed frame 5 together with the screw sleeve 101; the screw transmission can achieve very high positioning accuracy, usually reaching the micron level, which is very important for medical operations that require high precision.

[0102] As a preferred embodiment of the present invention, Figure 6 As shown, the clamping assembly 11 includes:

[0103] Bottom plate 111, such as Figure 2 and Figure 6 As shown, it is fixed to the bottom end of the mobile frame 9, and the bottom plate 111 is in contact with the bottom of the syringe;

[0104] The second screw rod 112 is threadedly connected with the movable frame 9;

[0105] Top plate 113, such as Figure 2 and Figure 4 As shown, the top plate 113 is located above the bottom plate 111 and is rotatably connected to the second screw rod 112. The top plate 113 is fixed with an optical axis 114 that is slidably connected to the moving frame 9;

[0106] The specific method of using the clamping assembly 11 is as follows: the position of the screw rod 112 and the movable frame 9 is adjusted by rotating the screw rod 112. Since the top plate 113 is rotatably connected to the screw rod 112, the position of the top plate 113 and the movable frame 9 also changes. In order to prevent the top plate 113 from rotating, an optical axis 114 is set, so that when the screw rod 112 rotates, the optical axis 114 and the top plate 113 slide relative to the movable frame 9; when the syringe is fixed, the syringe is first placed on the bottom plate 111 from the side. In order to increase the contact area, one side of the movable frame 9 is set as an arc surface. After the syringe is in close contact with the arc surface, the screw rod 112 is rotated to make the top plate 113 contact with the top of the syringe to prevent the movable frame 9 and the syringe from sliding.

[0107] If only the top plate 113 and the bottom plate 111 are used to fix the syringe, it is very likely that the syringe will be misplaced. In order to prevent the misplacement, the present invention makes the following improvements: Figure 2 and Figure 6 As shown, the clamping assembly 11 also includes:

[0108] The screw rod 3 115 is threadedly connected with the movable frame 9;

[0109] The side plate 116 is rotatably connected to the screw rod 3 115, and the side plate 116 is fixed with an optical axis 2 117 slidably connected to the moving frame 9;

[0110] When the side plate 116 is working, the screw rod 3 115 is rotated to make the side plate 116 and the optical axis 2 117 approach the syringe, so that the side plate 116 contacts the surface of the syringe. Figure 6 As shown, the side plate 116, the top plate 113 and the bottom plate 111 form a triangle, which limits the syringe in three directions and improves the stability of the syringe.

[0111] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0112] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
