Description

Technical Field

[0001] This disclosure relates to the field of surgical instrument technology, and more specifically, to a device for fixing arteriovenous puncture in the upper limb of a patient undergoing interventional surgery. Background Technology

[0002] Interventional surgery is a minimally invasive procedure, typically performed through a small incision in the skin, without requiring open surgery to expose the lesion. It is used in the treatment of various diseases, such as cardiovascular diseases, gastrointestinal tumors, and bleeding disorders. Elbow vein puncture is suitable for many interventional procedures, especially when the procedure requires access to the body via a vein. For example, varicocele embolization can be performed through the median cubital vein. This procedure has advantages such as simplicity, few complications, and rapid recovery; however, the patient's elbow needs to be immobilized for 6 hours post-procedure.

[0003] Chinese Patent Publication No. CN222150076U discloses a fixation device after puncture in cardiovascular interventional surgery, including a pressure ball fixed to one end of a right-angle rod. The end of the right-angle rod away from the pressure ball is fixedly connected to one side of a vertical sleeve. The middle part of the vertical sleeve is threaded onto a first vertical screw. The top of the first vertical screw is provided with a driven gear, which is connected to a driving gear via a gear belt. The driving gear is fixed on the motor shaft of a first motor. The bottom end of the first vertical screw is rotatably connected to the top of a horizontal sleeve via a first bearing. The middle part of the horizontal sleeve is threaded onto the horizontal screw. The vertical sleeve can move up and down along the first vertical screw to drive the pressure ball to press on the patient's puncture site. The pressure intensity of the pressure ball is controlled by the first motor, and the pressure ball is driven by a second motor for lateral adjustment. This device is fixed to the edge of the bed by an upper clamping plate and a lower clamping plate.

[0004] The fixation device used in this cardiovascular interventional procedure cannot provide prolonged immobilization and fixation of the elbow after the previous puncture, nor can it protect the puncture site. This makes the puncture site easily touched, and the wound is susceptible to external irritation and friction, which is detrimental to the patient's recovery. Utility Model Content

[0005] The purpose of this disclosure is to provide a fixation device for arteriovenous puncture in the upper limb of patients undergoing interventional surgery. This device prevents the puncture site from being touched, which is beneficial for the patient's better recovery.

[0006] To achieve the above objectives, this disclosure provides a fixation device for arteriovenous puncture of the upper limb in patients undergoing interventional surgery, comprising: a first support member for supporting the upper limb; a protective cover disposed on the first support member and capable of selectively covering the puncture site of the upper limb, wherein the protective cover is provided with a pressing element; and two sets of clamping assemblies, the two sets of clamping assemblies respectively corresponding to the upper arm and forearm of the upper limb, and the protective cover being disposed between the two sets of clamping assemblies.

[0007] Optionally, the protective cover is constructed in an arc shape to form an opening for the upper limb to pass through. One end of the protective cover is rotatably connected to the first support member, and the other end is detachably connected to the first support member. The pressing member is radially inserted into the protective cover, and the pressing member is provided with a pressing part located in the opening.

[0008] Optionally, the first support member has an adjustable first slider and a second slider along the extension direction of the opening, the first slider and the second slider are arranged opposite to each other, one end of the protective cover is rotatably connected to the first slider, and the other end is detachably connected to the second slider.

[0009] Optionally, the pressing component includes a sleeve and a movable rod arranged coaxially. The sleeve passes radially through the protective cover, and the movable rod is adjustablely disposed inside the sleeve, with the pressing part provided on the movable rod.

[0010] Optionally, the pressing member further includes an elastic reset member, which is sleeved on the movable rod, with one end of the elastic reset member abutting against the pressing part and the other end abutting against the sleeve.

[0011] Optionally, the elastic reset member is constructed as a torsion spring, the sleeve has a helical groove, the helical groove has a communicating helical section and a limiting section, the movable rod is provided with a limiting post, the limiting post slides through the helical groove, wherein the movable rod has a first position and a second position.

[0012] In the first position, the limiting post is engaged with the limiting segment, the elastic reset member is in a stretched state, and the pressing part abuts against the puncture site;

[0013] In the second position, the limiting post disengages from the limiting section, the elastic reset member is in a reset state, and a gap is formed between the pressing part and the puncture site.

[0014] Optionally, the interventional surgery patient's upper limb arteriovenous puncture fixation device further includes a second support member, which is arranged at an angle to the first support member and connected by a connecting rod. The second support member is provided with a first elastic band, wherein the second support member is arranged parallel to the axis of the first elastic band.

[0015] Optionally, the first elastic band is provided with two second elastic bands opposite each other, the second elastic bands being used to fit around the patient's shoulders.

[0016] Through the above technical solution, in the interventional surgery patient upper limb arteriovenous puncture fixation device provided in this disclosure, a protective cover is set on the first support member, and a pressing member is provided on the protective cover. Since the protective cover can selectively cover the puncture site of the upper limb, the protective cover has the function of "covering" or "exposing" the puncture site. When the protective cover covers the puncture site, it can prevent airborne droplets, dust and other pollutants from directly contacting the puncture site, and can also avoid external force touching the puncture site, which is conducive to better patient recovery. When the protective cover exposes the puncture site, it can provide direct visual feedback, which is conducive to medical staff to observe and perform nursing operations.

[0017] In addition, this application provides two sets of clamping components, with a protective cover positioned between the two sets of clamping components. This allows the patient's upper arm and forearm to be fixed separately using the two sets of clamping components when using the device, improving the overall stability of the upper limb fixation, facilitating long-term immobilization and fixation of the elbow, and effectively preventing the puncture point from being pulled or rubbed by external forces.

[0018] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0029] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0030] In this disclosure, unless otherwise stated, "inner" and "outer" refer to "inner" and "outer" relative to the contour of the corresponding component itself. Furthermore, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not imply sequentiality or importance. Additionally, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0031] According to exemplary embodiments of this disclosure, reference is made to Figure 1 As shown, an upper limb arteriovenous puncture fixation device for interventional surgery patients is provided, including: a first support member 1 for supporting the upper limb; a protective cover 2 disposed on the first support member 1 and capable of selectively covering the puncture site of the upper limb, wherein the protective cover 2 is provided with a pressing member 3; and two sets of clamping components 4, the two sets of clamping components 4 respectively corresponding to the upper arm and forearm of the upper limb, and the protective cover 2 disposed between the two sets of clamping components 4.

[0032] Through the above technical solution, in the interventional surgery patient upper limb arteriovenous puncture fixation device provided in this disclosure, a protective cover 2 is set on the first support member 1, and a pressing member 3 is provided on the protective cover 2. Since the protective cover 2 can selectively cover the puncture site of the upper limb, the protective cover 2 has the function of "covering" or "exposing" the puncture site. When the protective cover 2 covers the puncture site, it can prevent airborne droplets, dust and other pollutants from directly contacting the puncture site, and can also avoid external force touching the puncture site, which is conducive to better patient recovery. When the protective cover 2 exposes the puncture site, it can provide direct visual feedback, which is conducive to medical staff to observe and perform nursing operations.

[0033] In addition, this application provides two sets of clamping components 4, with a protective cover 2 located between the two sets of clamping components 4. This allows the patient's upper arm and forearm to be fixed separately using the two sets of clamping components 4 when using the device, improving the overall stability of the upper limb fixation, facilitating long-term immobilization and fixation of the elbow, and effectively preventing the puncture point from being pulled or rubbed by external forces.

[0034] According to exemplary embodiments of this disclosure, reference is made to Figures 1 to 4 As shown, the protective cover 2 can be constructed as an arc-shaped structure to form an opening 20 for the upper limb to pass through. One end of the protective cover 2 is rotatably connected to the first support member 1, and the other end is detachably connected to the first support member 1. A pressing member 3 is radially inserted into the protective cover 2, and the pressing member 3 is provided with a pressing part 31 located within the opening 20. With the above configuration, when the end of the protective cover 2 detachably connected to the first support member 1 is disconnected from the first support member 1, the other end of the protective cover 2 can rotate around the first support member 1 to expose the puncture site, thereby facilitating adjustment according to usage needs and improving the flexibility and convenience of use.

[0035] In this disclosure, the pressing part 3 is used to press and stop bleeding at the puncture site, which can effectively reduce bleeding and reduce the risk of hematoma formation. The pressing part 31 can be made of a flexible material to avoid squeezing the wound due to hard contact.

[0036] According to exemplary embodiments of this disclosure, reference is made to Figure 3 and Figure 4 As shown, the first support member 1 may have an adjustable first slider 11 and a second slider 12 along the extension direction of the opening 20. The first slider 11 and the second slider 12 are arranged opposite to each other. One end of the protective cover 2 is rotatably connected to the first slider 11, and the other end is detachably connected to the second slider 12. In the above technical solution, both ends of the protective cover 2 are connected to the first slider 11 and the second slider 12 respectively. Since the first slider 11 and the second slider 12 are adjustable along the extension direction of the opening 20, the protective cover 2 can also be adjusted along the extension direction of the opening 20 to adapt to the arm lengths of different patients and improve versatility.

[0037] In this disclosure, the first slider 11 and the second slider 12 can be made adjustable on the first support member 1 by adopting any structure, thereby realizing the position adjustment of the protective cover 2 along the extension direction of the opening 20. This disclosure does not impose any specific restrictions on this.

[0038] In one exemplary embodiment, reference is made to Figure 3 and Figure 4 As shown, two first sliding grooves 13 can be spaced apart on the first support member 1. The first slider 11 and the second slider 12 are slidably connected to the two first sliding grooves 13 respectively. Side grooves 14 are respectively opened on the side walls of the two first sliding grooves 13, and the two side grooves 14 are connected to the corresponding first sliding grooves 13. On this basis, first studs 15 are respectively provided on the first slider 11 and the second slider 12, so that the first studs 15 slide through the corresponding side grooves 14. In this way, after the first slider 11 and the second slider 12 are moved to the appropriate position, the position of the first slider 11 and the second slider 12 can be locked by the thread engagement of the nut and the first stud 15, that is, the position of the protective cover 2 can be locked, which improves the convenience of operation and ensures the reliability of the fixed protective cover 2.

[0039] The protective cover 2 and the second slider 12 can be connected by any detachable method, such as threaded connection or snap-fit, and this disclosure does not impose any specific limitations on this. In an exemplary embodiment, a snap-fit ​​protrusion 121 can be provided on one of the second slider 12 and the protective cover 2, and a snap-fit ​​groove 21 can be provided on the other. The protective cover 2 and the second slider 12 can be detachably connected by snap-fit ​​connection between the snap-fit ​​protrusion 121 and the snap-fit ​​groove 21. This makes it convenient to connect or disconnect the protective cover 2 and the second slider 12 according to usage requirements, that is, to selectively use the protective cover 2 to cover the puncture site of the upper limb.

[0040] According to exemplary embodiments of this disclosure, reference is made to Figures 2 to 4 As shown, the pressing component 3 may include a sleeve 32 and a movable rod 33 arranged coaxially. The sleeve 32 passes radially through the protective cover 2, and the movable rod 33 is adjustablely disposed within the sleeve 32, with a pressing part 31 provided on the movable rod 33. By providing the sleeve 32, the movable rod 33 is guided. The sleeve 32 and the protective cover 2 may be integrally formed or fixedly connected in other ways. Since the movable rod 33 is adjustablely disposed within the sleeve 32, the position of the pressing part 31 can be adjusted by adjusting the position of the movable rod 33. Thus, the pressing component 3 can be selectively used to press the puncture site according to actual needs.

[0041] According to exemplary embodiments of this disclosure, reference is made to Figure 3 and Figure 4 As shown, the pressing member 3 may further include an elastic reset member 34, which is sleeved on the movable rod 33, with one end of the elastic reset member 34 abutting against the pressing part 31 and the other end abutting against the sleeve 32. By providing the elastic reset member 34, an automatic reset function is achieved, allowing the movable rod 33 to automatically reset to the set position, thus improving the convenience of operation.

[0042] According to exemplary embodiments of this disclosure, reference is made to Figure 3 and Figure 4 As shown, the elastic reset member 34 can be constructed as a torsion spring. A spiral groove 320 is formed on the sleeve 32. The spiral groove 320 has a connected spiral section 321 and a limiting section 322. A limiting post 331 is provided on the movable rod 33. The limiting post 331 slides through the spiral groove 320. The movable rod 33 has a first position and a second position. In the first position, the limiting post 331 is engaged with the limiting section 322, the elastic reset member 34 is in a stretched state, and the pressing part 31 abuts against the puncture site. In the second position, the limiting post 331 disengages from the limiting section 322, the elastic reset member 34 is in a reset state, and a gap is formed between the pressing part 31 and the puncture site.

[0043] Understandably, in the above technical solutions, refer to 3 and Figure 4 As shown, there is a transition section 323 between the spiral section 321 and the limiting section 322. When the movable rod 33 is rotated counterclockwise, the limiting post 331 moves along the spiral groove 320. When the limiting post 331 moves to the transition section 323, it can be moved to the limiting section 322 through the transition section 323 to engage with the limiting section 322, thereby locking the movable rod 33 in the first position. In this state, the torsion spring is in a stretched state, and the pressing part 31 of the pressing member 3 abuts against the puncture part. Applying pressure to the puncture site to stop bleeding; when pressure is not required at the puncture site, the limiting post 331 is moved in the opposite direction to the above. When the limiting post 331 reaches the transition section 323, the external force is removed. At this time, the torsion spring restores its elastic deformation, driving the limiting post 331 to move towards the spiral section 321 until the limiting post 331 returns to the reset position. At this time, the limiting post 331 drives the movable rod 33 to reset to the second position, and a gap is formed between the pressing part 31 and the puncture site, that is, no pressure hemostasis operation is performed.

[0044] Please refer to Figure 6 and Figure 7As shown, the clamping assembly 4 of this disclosure may include clamping fingers 41, a third slider 42, and a locking member. Each clamping assembly 4 includes two clamping fingers 41 arranged opposite to each other. Each clamping finger 41 is provided with a third slider 42. The clamping fingers 41 are slidably connected to the first support member 1 through the third slider 42. In this way, the distance between the two opposite clamping fingers 41 can be adjusted to adapt to patients with different arm widths and to fix the arms of different patients. The locking member is used to lock the position of the clamping fingers 41 to ensure reliable fixation of the patient's upper limb (i.e., arm).

[0045] In the above technical solution, refer to Figure 6 As shown, a second slide groove 16 can be opened on the first support member 1, so that the third slider 42 can be slidably connected with the second slide groove 16, thereby realizing the slidable connection between the third slider 42 and the first support member 1. The locking member is set in the same way as the locking method of the first slider 11, that is, a second stud 43 that can move along the second slide groove 16 can be set on the third slider 42. The specific setting method is the same as that of the first stud 15, which will not be described in detail here. Similarly, the position of the third slider 42 is locked by the threaded engagement of the nut and the second stud 43, that is, the position of the finger clamp 41 is locked. In this way, the clamping assembly 4 can be adjusted in the above manner to meet the fixation needs of different patients' arms.

[0046] To ensure better grip between the finger clamp 41 and the arm, refer to... Figure 7 As shown, the gripping surface of the finger clip 41 can be constructed as an arc-shaped surface to better fit the arm.

[0047] According to exemplary embodiments of this disclosure, reference is made to Figure 1 As shown, the upper limb arteriovenous puncture fixation device for interventional surgery patients may further include a second support member 5. The second support member 5 is arranged at an angle to the first support member 1 and connected by a connecting rod 6. The second support member 5 is provided with a first elastic band 7, wherein the second support member 5 is arranged parallel to the axis of the first elastic band 7. The first elastic band 7 is used to fit over the patient's chest. This arrangement can support and reinforce the first support member 1. The connecting rod 6 improves the stability of the second support member 5 and the first support member 1.

[0048] Based on the above, and according to exemplary embodiments of this disclosure, refer to Figure 1 As shown, two second elastic bands 8 are provided on the first elastic band 7. The second elastic bands 8 are used to fit around the patient's shoulder to improve the overall stability of the upper limb arteriovenous puncture fixation device worn by the patient in this interventional surgery.

[0049] Reference Figures 1 to 7 As shown in the diagram, the method of using the arteriovenous puncture fixation device for upper limb arteriovenous puncture in interventional surgery patients disclosed herein is detailed below:

[0050] The first elastic band 7 is attached to the upper chest of the patient, and the second elastic band 8 is attached to the patient's shoulders. The second support 5 is placed under the patient's armpit and on one side of the patient's body. The patient's arm is placed on the first support 1, so that the patient's upper arm and forearm correspond to the two clamping components 4 respectively. Then, the clamping width is adjusted by sliding the clamping finger 41, and the nuts are tightened with each of the second studs 43 in sequence to complete the fixation of the patient's upper arm and forearm. Thus, the upper limb arteriovenous puncture fixation device of the interventional surgery patient disclosed herein is completed, so that the patient's upper limb is reliably fixed to the trunk, avoiding the impact on the puncture site during the patient's walking or activities, thereby facilitating better recovery for the patient.

[0051] After the protective cover is worn, when it is necessary to protect the puncture site, first engage the protrusion 121 and the slot 21 to connect the protective cover 2 with the second slider 12, then slide the protective cover 2 to the desired position so that the protective cover 2 is above the puncture site. After the protective cover 2 has slid to the desired position, tighten the nut and the first stud 15 to fix the protective cover 2.

[0052] When pressure hemostasis is required, rotate the movable rod 33 counterclockwise. The limiting post 331 will move along the spiral groove 320 to engage with the limiting section 322, thereby locking the movable rod 33 in the first position. At this time, the pressing part 31 of the pressing member 3 abuts against the puncture site to achieve pressure hemostasis at the puncture site. When pressure hemostasis is not required, move the limiting post 331 in the opposite direction to disengage the limiting post 331 from the limiting section 322. The operation is convenient.

[0053] When it is necessary to expose the puncture site, disconnect the connection between the cam 121 and the slot 21. At this time, the free end of the protective cover 2 can be rotated so that the protective cover 2 can rotate around one end, thereby removing the obstruction of the puncture site. The protective cover 2 can be selectively activated to cover the puncture site according to the usage needs, which is flexible and can better meet the usage needs of patients.

[0054] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0055] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0056] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
