Abstract
Description
Technical Field
[0001] This utility model relates to the field of PICC placement auxiliary tools, specifically a B-ultrasound probe needle holding device. Background Technology
[0002] PICC (Peripherally Inserted Central Catheter) placement involves inserting a thin catheter through a vein in the hand into the inferior vena cava. Its primary purpose is to administer medications via this catheter. Some medications are highly irritating, and infusion through peripheral veins can cause pain or even lead to the death of the vein, rendering the medication unusable. Inserting a catheter through a peripheral vein allows for continuous medication administration. When not in use, the catheter is sealed with heparin, and it can be reopened for continued administration when needed. This is very convenient, eliminating the need for repeated punctures and reducing patient discomfort.
[0003] When patients require long-term intravenous infusion, repeated administration of chemotherapy drugs, mannitol, fat emulsions, amino acids, or when their condition is critical and requires the establishment of intravenous access, a venous access can be established through peripheral venous puncture central venous catheterization, allowing the drugs to enter the body quickly to achieve the therapeutic effect.
[0004] For elderly patients with a long disease course or other types of patients, after multiple injections or punctures, their fragile blood vessels can no longer withstand repeated injections, making subsequent intravenous infusion therapy difficult. Therefore, ultrasound probes can visually display the vascular anatomy, allowing for the selection, assessment, measurement, and precise positioning of the target vessel for real-time guided puncture, greatly improving the success rate of catheter placement. Traditional PICC puncture is performed on a visible vessel at the patient's elbow, requiring the vessel to be visible or palpable and relatively large. After insertion, the patient's movement is somewhat restricted, and repetitive flexion and extension movements are not advisable. This places certain demands on the patient's blood vessels and significantly limits patient mobility. In contrast, ultrasound-guided PICC placement offers clear advantages.
[0005] When PICC placement is used in conjunction with an ultrasound probe, a puncture-enabled ultrasound probe with a needle holder is required. These probes are expensive, and hospitals typically don't have a large number of them. Currently, the most common type of ultrasound probe in hospitals nationwide is the ordinary superficial ultrasound probe. Conventional superficial ultrasound probes are usually used to examine blood vessels near the body surface, such as arteries or veins in the limbs and neck. Because ordinary probes cannot be fitted with a needle holder, they cannot be used for puncture in clinical practice. This results in a shortage of ultrasound probes with puncture-enabled needle holders, often leading to a shortage. Furthermore, existing equipment is expensive and suffers from installation instability. Utility Model Content
[0006] The purpose of this invention is to solve the problems that ordinary ultrasound probes cannot be used for puncture in clinical practice, and that existing equipment is expensive and has poor installation stability.
[0007] To solve the above-mentioned technical problems, the present invention provides a B-ultrasound probe needle holding device, comprising:
[0008] A first fixing sleeve having a fixedly connected puncture mounting seat;
[0009] A second fixing sleeve has an opening, and the opening of the second fixing sleeve is detachably connected; the first fixing sleeve and the second fixing sleeve are connected by at least one flexible connector;
[0010] A puncture component, which is detachably mounted to the puncture mounting base; the surface of the puncture component has a guide connection groove.
[0011] In a preferred embodiment of the ultrasound probe needle holding device of this utility model, the circumferences of the openings at both ends of the first fixing sleeve and the second fixing sleeve are different.
[0012] As a preferred embodiment of the B-ultrasound probe needle holding device of this utility model, one end of the puncture mounting seat has a fixedly connected limiting edge, and the other end of the puncture mounting seat has limiting countersunk holes on both sides respectively.
[0013] One end of the puncture component has a groove, and the other end of the puncture component has positioning protrusions on both sides; when the puncture component is installed on the puncture mounting base, the limiting edge is in the groove and the positioning protrusion is in the limiting countersunk hole.
[0014] In a preferred embodiment of the ultrasound probe needle holding device of this utility model, one end of the opening has a fixedly connected positioning plug; the other end of the opening has a connecting buckle, and the connecting buckle has a connecting hole; the positioning plug is detachably installed in the connecting hole.
[0015] As a preferred embodiment of the ultrasound probe needle holding device of this utility model, the fixed connection between the first fixing sleeve and the puncture mounting seat is deleted;
[0016] One end of the puncture mounting seat is movably connected to the first fixing sleeve, and the other end of the puncture mounting seat is detachably connected to the first fixing sleeve.
[0017] In a preferred embodiment of the ultrasound probe needle holding device of this utility model, one end of the puncture mounting seat has a shaft hole;
[0018] The first fixing sleeve has a fixedly connected shaft seat;
[0019] It includes a shaft that passes through the shaft hole and is movably connected to the shaft seat.
[0020] As a preferred embodiment of the ultrasound probe needle holding device of this utility model, the other end of the puncture mounting seat has a screw hole;
[0021] The first fixing sleeve has a fixedly connected limiting seat; the limiting seat has a locking position in the middle, which corresponds to the screw hole;
[0022] It includes a lead screw, one end of which has a fixedly connected knob; the other end of the lead screw passes through the locking position and is threadedly connected to the screw hole.
[0023] In a preferred embodiment of the ultrasound probe needle holding device of this utility model, the diameter of the knob is larger than the width of the locking position.
[0024] Beneficial effects
[0025] This utility model solves the above-mentioned existing problems and other existing problems not mentioned above, and brings at least the following innovative advantages:
[0026] This utility model relates to a B-mode ultrasound probe needle-holding device. By mounting the puncture component onto a puncture mounting seat on a first fixed sleeve, and through the addition of a second fixed sleeve and a flexible connector connecting the first and second fixed sleeves, this invention upgrades a conventional B-mode ultrasound probe, enabling it to hold a needle and facilitating needle manipulation. Furthermore, the cooperation between the first and second fixed sleeves and the flexible connector ensures a more stable installation.
[0027] This utility model of a B-ultrasound probe needle holding device changes the connection between the puncture mounting seat and the first fixed sleeve to a movable connection, allowing the angle of the puncture mounting seat and the puncture component to be adjusted according to usage requirements. The limiting seat and locking position fixedly connected to the first fixed sleeve, along with the threaded rod and knob connected to the screw hole of the puncture mounting seat, enable the knob to abut against or move away from the limiting seat using the threaded connection between the threaded rod and the screw hole. When the knob abuts against the limiting seat, the friction between the knob and the limiting seat can be used to position the puncture mounting seat. Attached Figure Description

[0038] In the accompanying drawings, the same reference numerals represent the same parts. It should be noted that the described embodiments are only some, not all, of the embodiments disclosed herein.
[0039] Based on the embodiments described in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure.
[0040] Example 1
[0041] like Figures 1 to 4 As shown, the ultrasound probe needle holding device of this utility model includes a first fixing sleeve 1. Figure 2 The first fixing sleeve 1 is shown to have a fixedly connected puncture mounting seat 2; wherein Figure 2 The specific structure of the puncture mounting seat 2 is shown. This includes the second retaining sleeve 3, such as... Figure 1 and Figure 2As shown, the second fixing sleeve 3 has an opening 4, meaning that the second fixing sleeve 3 is a ring that is not connected end to end; therefore, the opening 4 of the second fixing sleeve 3 is detachably connected; as... Figure 1 and Figure 2 As shown, one end of the opening 4 has a fixedly connected positioning plug 12; the other end of the opening 4 has a connecting buckle 13, and the connecting buckle 13 has a connecting hole 14; the positioning plug 12 is detachably installed in the connecting hole 14; the opening 4 of the second fixing sleeve 3 is connected to the second fixing sleeve 3 by the positioning plug 12 and the connecting buckle 13. The first fixing sleeve 1 and the second fixing sleeve 3 are connected by at least one flexible connector 5; as shown Figure 1 , Figure 2 and Figure 7 As shown, the openings 4 at both ends of the first fixing sleeve 1 and the second fixing sleeve 3 have different perimeters, meaning that the cross-sections of the first fixing sleeve 1 and the second fixing sleeve 3 are tapered shapes with their tips cut off. It includes a piercing component 6, which is detachably mounted to the piercing mounting base 2; the surface of the piercing component 6 has a guide connecting groove 7. Figure 4 The installation effect of this utility model on the ultrasonic probe 22 is shown.
[0042] This utility model relates to a B-mode ultrasound probe needle-holding device. By mounting the puncture component 6 onto the puncture mounting seat 2 on the first fixing sleeve 1, and by adding a second fixing sleeve 3 and a flexible connector 5 connecting the first fixing sleeve 1 and the second fixing sleeve 3, this utility model enables the upgrading of a common B-mode ultrasound probe to have a needle-holding function, facilitating the operation of the puncture needle. Furthermore, the cooperation of the first fixing sleeve 1, the second fixing sleeve 3, and the flexible connector 5 also ensures a more stable installation.
[0043] like Figure 2 As shown, one end of the puncture mounting base 2 has a fixedly connected limiting edge 8, and the other end of the puncture mounting base 2 has limiting countersunk holes 9 on both sides respectively. Figure 3 The puncture component 6 is shown to have a groove 10 at one end and positioning protrusions 11 on both sides of the other end. When the puncture component 6 is installed on the puncture mounting base 2, the limiting edge 8 is in the groove 10 and the positioning protrusions 11 are in the limiting countersunk hole 9.
[0044] Example 2
[0045] like Figures 5 to 8 As shown, the design of the ultrasound probe needle holder of this utility model is the same as that of Embodiment 1. Therefore, this Embodiment 2 includes all the contents of Embodiment 1. The difference is that the fixed connection between the first fixing sleeve 1 and the puncture mounting seat 2 in the embodiment is deleted.
[0046] See Figures 5 to 8 One end of the puncture mounting seat 2 is movably connected to the first fixing sleeve 1, and the other end of the puncture mounting seat 2 is detachably connected to the first fixing sleeve 1. A more specific embodiment of the movable connection between the puncture mounting seat 2 and the first fixing sleeve 1 is described in [reference needed]. Figure 6 One end of the puncture mounting seat 2 has a shaft hole 15; the first fixing sleeve 1 has a fixedly connected shaft seat 16;
[0047] It includes a shaft 17, which passes through the shaft hole 15 and is movably connected to the shaft seat 16. That is, the movable connection between the puncture mounting seat 2 and the first fixed sleeve 1 is achieved through the shaft hole 15, the shaft seat 15, and the shaft 17.
[0048] In addition to the above, a screw hole is provided at the other end of the puncture mounting base 2; for example... Figure 5 , Figure 6 and Figure 7 and Figure 8 As shown, the first fixed sleeve 1 has a fixedly connected limiting seat 18; Figure 6 The limiting seat 18 is shown to have a locking position 19 in the middle, which corresponds to the screw hole; it also includes a lead screw 20. Figure 5 The diagram shows a lead screw 20 with a knob 21 fixedly connected to one end; the other end of the lead screw 20 passes through the locking slot 19 and is threaded into the screw hole; and the diameter of the knob 21 is larger than the width of the locking slot 19. Figure 8 The diagram shows the effect of applying this embodiment 2 to the ultrasonic probe 22.
[0049] This utility model of a B-ultrasound probe needle holder device changes the connection between the puncture mounting seat 2 and the first fixed sleeve 1 to a movable connection, allowing the angle of the puncture mounting seat 2 and the puncture component 6 to be adjusted according to usage requirements. The limiting seat 18 and the locking position 19 fixedly connected to the first fixed sleeve 1, as well as the screw rod 20 and the knob 21 threadedly connected to the screw hole of the puncture mounting seat 2, realize the use of the threaded connection between the screw rod 20 and the screw hole to make the knob 21 abut against or move away from the limiting seat 18. When the knob 21 abuts against the limiting seat 18, the friction between the knob 21 and the limiting seat 18 can be used to position the puncture mounting seat 2.
