Problems solved by technology

[0004] The above two inventions both achieve the purpose of miniaturization of the probe, but due to the limitation of the shape of the probe, the ultrasonic probe is still limited to the hand-held type. In clinical use, it is found that after the doctor holds the ultrasonic probe with one hand, the other hand cannot complete For the puncture operati

Example Embodiment

[0029] Example 1:

[0030] A finger sleeve type ultrasonic probe includes a shell, a transducer 4 and other components related to the transducer. The shell is composed of a finger sleeve 1 and a casing 2. The finger sleeve is a cylinder with a through hole inside. The finger sleeve 1 has a double-layer structure. The outer layer is made of a material with a certain hardness, and the inner layer is relatively soft. The finger can penetrate into the finger sleeve 1. The shell 2 is located outside the outer circle of the finger cuff 1. When the fingers are put into the finger cuff 1, the shell will be at the finger pad. The shell 2 has a cavity inside, the top is not closed, and the bottom has a hole. The side wall of the casing 2 and the finger sleeve are connected by bolts. The transducer 4 and related accessories are installed inside the casing 2. The acoustic window 41 of the transducer 4 corresponds to the hole 21 on the casing 2. The acoustic window 41 can pass through the ho...

Example Embodiment

[0031] Example 2:

[0032] Such as Figure 1 ~ Figure 3 As shown, there is a finger sleeve type ultrasonic probe, and the rest is the same as in Embodiment 1. The casing further includes a connecting device 3, and the top of the casing 2 is closed. The connecting device 3 is a slider 31 and a slider base 32. The slider 31 is installed in the slider base 32, and the slider base 32 is fixed to the top of the casing 2. On both sides of the finger sleeve in the circumferential direction, there are two slide rails 11 that are mirrored with respect to the casing 2. After the slider 31 on the connecting device 3 is clamped with the slide rail 11, the connecting device 3 and the casing 2 can be made around the finger sleeve. Circumferential movement. The included angle formed by the two ends of the slideway 11 and the axial direction of the finger cuff is 15°, so the circumferential movement angle of the casing 2 around the finger cuff 1 is 15°, which meets the requirements of general ...

Example Embodiment

[0033] Example 3:

[0034] Such as Figure 4 , Figure 5 A finger sleeve type ultrasonic probe is shown, and the rest is the same as in Embodiment 1. The object includes a connecting device 3. The connecting device 3 is a universal joint, and the two universal joint forks of the universal joint are respectively connected with the finger sleeve 1 and the casing 2, wherein the connection with the casing 2 is completed by a connecting shaft 33. Through the connection of the universal joint, the ultrasonic probe can complete the circumferential movement around the finger cuff and back and forth movement. Both ends of the finger cuff 1 are smooth curved surfaces, and the intersection of the side surface of the casing 2 and the finger cuff 1 is also relatively smooth, so that the freedom of the ultrasonic probe in two directions is not hindered. There are two stoppers 12 on both sides of the finger sleeve 1 in the circumferential direction that are mirrored with respect to the casing ...

Abstract

The invention relates to the field of mechanical facilities, in particular to a fingerstall type ultrasonic probe which is used for coordinating puncture operation. The fingerstall type ultrasonic probe comprises a casing, a connection device and a transducer. The casing comprises a tube-sleeve-shaped fingerstall and a casing body, wherein the casing body is fixed on the excircle side of the fingerstall. A cavity is formed in the casing body, a hole is formed in the bottom of the casing body, the transducer is installed in the casing body, and an acoustic window of the transducer is corresponding to the hole of the casing body. The connection device can move in the circumferential direction of the fingerstall after one end of the connection device is connected with the fingerstall, and the other end of the connection device is fixedly connected with the casing body. The fingerstall type ultrasonic probe is small in size; doctors can perform ultrasound detection and puncture operation simultaneously after they sleeve the probe in their fingers, and thus the operation steps are simplified. During operation, the expected effect can be achieved by slightly moving the fingerstall type ultrasonic probe, and the puncture success rate is improved. The connection device capable of moving in the circumferential direction of the fingerstall is additionally arranged between the casing body and the fingerstall so the detection area of the probe is enlarged and the problem of small probes of being limited in the field of view is solved.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a finger cuff type ultrasonic probe suitable for blood vessel puncture. Background technique [0002] Vascular puncture technology is one of the most commonly used invasive operations in hospitals. Related vascular puncture can provide patients with infusion, blood transfusion, drug therapy, nutritional therapy, plasma exchange, dialysis, blood gas analysis, continuous arterial monitoring, heart, brain and major organs. An important channel for interventional treatment or other rescue measures. At present, the vast majority of puncture operations rely on clinicians to perform anatomical positioning of the body surface, clinical experience and hand feeling. The success rate of puncture is low, error-prone, and various puncture complications are prone to occur, threatening medical safety and bringing pain to patients. Even life-threatening. In recent years, ultrasound...
