Description
Technical Field
[0001] The utility model relates to the field of medical instruments, in particular to a blood vessel suturing device with an auxiliary rotation angle device. Background Art
[0002] At present, when performing interventional surgeries, such as vascular stent implantation, there will be varying degrees of damage to the blood vessels due to vascular puncture. In these cases, vascular suture devices are commonly used hemostatic tools in medical surgeries. When the caliber of the sheath tube needs to be sutured from 8.5F to 21F, at least two suture devices are required for pre-suturing.
[0003] Insert the first suture device through the guidewire until the guidewire outlet is close to the skin surface, remove the guidewire from the guidewire outlet, and continue to push the sheath with the right hand like a pen until uninterrupted pulsating blood is seen at the marked cavity port. At this time, the control handle and logo should remain vertical (12 o'clock direction); then rotate the instrument 30 degrees to the patient's right side (approximately 10 o'clock direction), and then perform a series of subsequent operations until the first suture device is withdrawn. When the second suture device is inserted, it should be rotated about 30 degrees to the patient's left side (approximately 2 o'clock direction) for subsequent suturing operations; after completing the suturing, observe the hemostatic effect. If the hemostatic effect is not satisfactory, insert the third suture device. The third suture device does not need to be rotated during insertion, and the LOGO direction should remain vertical (12 o'clock direction). It can be determined from the above description that the suturing process involves multiple rotation actions, and the appropriate angles achieved by the current rotation actions are all subjectively judged by the operator, and there is a possibility of angle deviation, which in turn affects the suturing effect. Therefore, it is necessary to propose a vascular suturing device with an auxiliary rotation angle device to solve various problems with respect to the angle problem. Utility Model Content

DETAILED DESCRIPTION
[0038] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.
[0039] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.
[0040] Example 1
[0041] In this embodiment, a vascular suture device with an auxiliary rotation angle device is provided. Figure 1-Figure 11 The vascular suture device with an auxiliary rotation angle device comprises a housing 5 , a sheath tube 1 and a push handle 6 disposed on both sides of the housing 5 , and a turning handle 4 rotatably disposed on the housing 5 .
[0042] The above structure is the main structure of the existing vascular suture device. The use of the vascular suture device is the existing technology in the field and will not be described in detail in this embodiment.
[0043] In this embodiment, the end of the housing 5 away from the push handle 6 is provided with a housing extension 7 and an angle rotation assembly 3 that traps the housing extension 7 .
[0044] For the angle rotation component 3, see Figure 1-Figure 8 , which includes a front cover 31 and a rear cover 32 trapped in the housing extension 7, such as Fig.11 As shown, the front cover 31 and the rear cover 32 can be combined to form a receiving space.
[0045] Further explanation, regarding the front cover 31, it includes a front cover body 311 of the snare shell extension 7, through holes 312 arranged on both sides of the front cover body 311, and guide grooves 313 arrayed on the inner side of the front cover body 311 for merging and connecting with the rear cover 32.
[0046] As for the rear cover 32 , it includes a rear cover body 321 of the snare housing extension 7 , a guide strip 322 arrayed on the inner side of the rear cover body 321 for inserting into the guide groove 313 , and a pin groove 324 .
[0047] Further explanation: the accommodation space is as follows Figure 2 and Figure 3 The two pressing plates 33 shown in the figure cross and circle the shell extension portion 7, and the pin 34 is inserted into the center of the intersection of the two pressing plates 33, and the end of the pin 34 extends into the pin groove 324; it should be noted that there is also a groove corresponding to the pin groove 324 and used to fix the pin 34 in the front cover body 311.
[0048] The two pressing sheets 33 have a vertical portion and a curved portion. The vertical portion after the two pressing sheets 33 cross each other forms a fixed space for placing the spring 35 , and the curved portion after the two pressing sheets 33 cross each other is encircled by the housing extension 7 .
[0049] As described above, the vertical part after the two pressing plates 33 cross each other forms a fixed space for placing the spring 35, see Figure 6 and Figure 7 , the spring 35 is placed in the fixed space of the spring 35; in this embodiment, in order to better fix the spring 35, the hole at the end of the pressing plate 33 corresponding to the spring 35 is provided with a spring fixing portion 36 extending into the spring 35, so that the spring 35 will be firmly fixed between the two pressing plates 33.
[0050] See also Figure 2 , Figure 3 as well as Figure 6 Each pressing sheet 33 is provided with a button fixing portion 37, and the button 38 fixed by the button fixing portion 37 extends outward through the through hole 312, and the outward extending portion is the part pressed by the person. The following examples illustrate the functions:
[0051] First, when the two buttons 38 are pressed, the spring 35 is squeezed by the two pressing pieces 33, and the two pressing pieces 33 are loosened from the housing extension 7;
[0052] Second, when the two buttons 38 are released, the spring 35 pushes the two pressing pieces 33 , so that the two pressing pieces 33 clamp the housing extension 7 .
[0053] To further explain, there is a first limiting plate 314 inside the guide groove 313 located in the rotation path of the two pressing plates 33, and a second limiting plate 323 is located inside the rear cover body 321 in the rotation path of the two pressing plates 33. The second limiting plate 323 and the first limiting plate 314 form a blocking portion for limiting the rotational travel of the two pressing plates 33 after the front cover body 311 and the rear cover body 321 are combined.
[0054] For further explanation, see Fig. 9 The initial length of the spring 35 is L, and the distance between the vertical parts of the two pressing plates 33 when they are parallel is L1, wherein the initial length L of the spring 35 is greater than L1. In this state, the vertical parts of the two pressing plates 33 will be stretched apart, and the curved parts of the two pressing plates 33 will be retracted.
[0055] See also Figure 2-Figure 4 , Figure 6 The second limiting piece 323 and the first limiting piece 314 will form a blocking portion after being combined. Figure 6 For reference, the distance between the two blocking parts is L2, and L2 is between L1 and L (L1<L2<L). In this way, after the vertical parts of the two pressing plates 33 contact the blocking parts, the spring 35 is squeezed. In this state, the curved part of the pressing plate 33 can maintain the inward compression and tightening force.
[0056] See also Fig.10 , the minimum diameter of the circle formed by the curved parts of the two pressing pieces 33 is D, the diameter of the housing extension 7 is D1, D1 is greater than D, and the two pressing pieces 33 will apply a clamping force to the housing extension 7. On the contrary, by pressing the buttons 38 on both sides, the springs 35 are compressed, the curved parts of the two pressing pieces 33 open to both sides, and the two pressing pieces 33 are loosened from the housing extension 7.
[0057] In this embodiment, in order to increase the clamping force of the pressing piece 33 on the shell extension portion 7, a rubber coating 9 may be added inside the pressing piece 33. The rubber coating 9 may be made of other suitable materials such as silicone or rubber.
[0058] In this embodiment, in order to prevent the angle rotation assembly 3 from being completely detached from the shell extension 7, a detachable shell cap 2 is provided at the end of the shell extension 7, and the shell cap 2 forms a protective structure to prevent the angle rotation assembly 3 from being completely detached from the shell extension 7 after being loosened.
[0059] The core of this embodiment is to clarify the deflection degree of the shell 5. For this purpose, three angle marking lines 325 are set on the outside of the back cover body 321, among which the central angle marking line 325 corresponds to 0°, and the two angle marking lines 325 on both sides of the central angle marking line 325 correspond to 30° and -30° respectively; the corresponding angle marking line 325 of the shell 5 is adapted with a zero degree mark 8.
[0060] It is further explained that the zero-degree mark 8 can be loosened from the shell extension 7 when the operator controls the angle rotation assembly 3 and rotates relative to the shell extension 7. The deflection angle of the shell 5 and the angle rotation assembly 3 can be clearly determined by comparing the three angle marking lines 325. It should be noted that the angle scale markings on the rear cover body 321 are not limited to ±30°, and corresponding scale markings can be added according to different clinical needs.
[0061] The operation process of this embodiment is as follows:
[0062] First, before use, confirm whether the zero-degree mark 8 on the housing is aligned with the 0° angle mark line 325. After confirmation, insert the first suture device through the guide wire until the guide wire outlet is close to the skin surface, and remove the guide wire from the guide wire outlet;
[0063] Second, continue to push the sheath tube 1 with your right hand like a pen until you see uninterrupted pulsating blood spray at the marked cavity port. At this time, confirm again that the 0° angle mark line 325 and the logo on the rear cover should remain vertical;
[0064] Third, according to clinical operation, the instrument needs to be rotated 30 degrees to the right side of the patient (approximately at 10 o'clock). At this time, the left hand fixes the angle rotation component 3, and the thumb and index finger simultaneously press the buttons 38 on both sides thereof to release the housing 5. The right hand uniformly rotates the housing 5 to the left by 30 degrees until the zero-degree mark 8 is aligned with the "-30°" angle mark line 325 on the rear cover body 321 and the button 38 is released, and then a series of subsequent operations are performed until the first stapler is withdrawn;
[0065] Fourth, when inserting the second suturing instrument, rotate the shell 5 30° to the right until the zero-degree mark 8 is aligned with the "-30°" angle mark line 325 on the rear cover body 321 and release the button 38 to perform subsequent suturing operations. During the entire operation, the 0° angle mark line 325 must be kept vertically upward at all times.
[0066] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
