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 operation, it is necessary to put down the probe immediately after the observation, and then re-hold the ultrasonic probe to detect the puncture position. This operation is not only cumbersome, but also does not effectively reflect the role of the ultrasonic probe. The hand that only operates the puncture needle will be affected, resulting in puncture errors

Embodiment 1

[0030] A finger cot type ultrasonic probe includes a shell, a transducer 4 and other accessories related to the transducer. The shell is composed of a finger cot 1 and a casing 2 . The fingertip is a cylinder with through holes inside. The fingertip 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 casing 2 is located on the outside of the outer circle of the finger cot 1. When the finger is inserted into the finger cot 1, the casing will be on the fingertip. There is a cavity inside the casing 2, the top is not closed, and the bottom has a hole. The side wall of the casing 2 is connected with the finger cot by bolts. The transducer 4 and related accessories are installed inside the casing 2, wherein the acoustic window 41 of the transducer 4 corresponds to the hole 21 on the casing 2, and the acoustic window 41 can pass through the hole 21 to contact the body surface for feedback signal ...

Embodiment 2

[0032] Such as Figure 1 ~ Figure 3 As shown, a finger-sleeve ultrasonic probe, the rest is the same as that of Embodiment 1, the housing also includes a connecting device 3, and the top of the housing 2 is closed. The connecting device 3 is a slider 31 and a slider seat 32 , the slider 31 is installed in the slider seat 32 , and the slider seat 32 is fixed on the top of the casing 2 . There are two slideways 11 distributed on both sides of the fingertip in the circumferential direction relative to the mirror surface of the casing 2. After the slider 31 on the connecting device 3 is engaged with the slideway 11, the connecting device 3 and the casing 2 can be formed around the fingertip. Circumferential movement. The angle formed between the two ends of the slideway 11 and the axial direction of the finger cuff is 15°, so the angle at which the casing 2 moves around the finger cuff 1 in the circumferential direction is 15°, which meets the needs of general testing.

Embodiment 3

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

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...
