Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a protective device at the connection point of an ultrasonic probe and its connecting wire. Background Technology

[0002] In the clinical application of ultrasound diagnostic equipment, the connection between the ultrasound probe and the connecting cable is the most critical weak point where the equipment is most prone to failure during operation. Because ultrasound examinations require flexible adjustment of the probe position according to different lesion locations, this connection point is frequently subjected to combined external forces such as bending, torsion, and tension.

[0003] In existing technologies, the protection of this connection relies solely on the cable's own insulation sheath, without any dedicated reinforcement or protective structure. This rudimentary protection method is highly susceptible to multiple problems after prolonged use due to repeated external forces: the outer sheath may crack or wear due to continuous friction and bending, exposing the internal conductors; the internal copper core conductors may break due to excessive stretching or twisting, or experience poor contact due to loose connections.

[0004] The aforementioned problems directly affect the normal operation of the equipment: on the one hand, the stability of signal transmission is severely interfered with, which may lead to noise and distortion in ultrasound images, thereby affecting the accuracy of clinical diagnosis and posing potential risks to disease assessment; on the other hand, frequent damage to connections forces medical institutions to regularly replace probes or connecting cables, which not only significantly increases equipment maintenance costs but also reduces diagnostic efficiency due to downtime during replacement. Furthermore, frequent component replacements also shorten the overall lifespan of the equipment, resulting in a waste of medical resources.

[0005] Therefore, developing a dedicated protective device that can provide comprehensive protection at the connection between the ultrasound probe and the connecting cable, and significantly improve the stability and durability of the connection, has become an urgent task to address current technical deficiencies and meet actual clinical needs. Utility Model Content

[0006] The purpose of this utility model is to provide a protective device at the connection between the ultrasound probe and the connecting cable to solve the above-mentioned problems. This device addresses the issue that the connection between the ultrasound probe and the connecting cable lacks a dedicated reinforcement and protection structure, which can easily lead to sheath wear, wire breakage, and poor contact when subjected to frequent external forces such as bending, torsion, and tension. This, in turn, affects diagnostic accuracy, increases medical costs, and reduces the lifespan and efficiency of the equipment.

[0007] To address the aforementioned problems, this utility model provides a technical solution: a protective device for the connection between an ultrasonic probe and its connecting cable, comprising a protective tube, a spring, an outer spiral groove, an inner spiral groove, a first retainer, and a second retainer; the spring is located inside the wall of the protective tube, and the protective tube is a flexible tube; the outer spiral groove is located on the outer side of the center between the spring's pitches, and is formed on the outer wall of the protective tube; the inner spiral groove is located on the inner side of the center between the spring's pitches, and is formed on the inner wall of the protective tube; the left side of the first retainer is connected to the right side of the protective tube; the right side of the second retainer is connected to the left side of the protective tube.

[0008] Preferably, the second fixing device has the same structure as the first fixing device and is symmetrically arranged. The specific structure of the first fixing device includes a connecting pipe, a stop pipe, an external thread, a locking pipe, an internal thread, a tightening surface, an internal conical hole, a clamping sleeve, an external conical surface, a groove, and a protrusion. A groove is provided on the inner wall of the left side of the connecting pipe, and the groove is connected to the protrusion on the right side of the protective pipe. The connecting pipe has an internal conical hole that is smaller on the left and larger on the right. The external thread is located on the outer right side of the connecting pipe. The locking pipe has an internal thread that is connected to the external thread. A tightening surface is provided on the right side of the locking pipe. The left side of the stop pipe is fixedly connected to the left side of the connecting pipe. The right side of the stop pipe is connected to the left side of the locking pipe. The clamping sleeve has an external conical surface that is smaller on the left and larger on the right, and the external conical surfaces are connected to each other. The right side of the clamping sleeve is connected to the tightening surface.

[0009] Preferably, the locking tube has anti-slip texture on the outer right side.

[0010] Preferably, the inside of the clamping sleeve matches the outside of the ultrasonic probe connection or the outside of the connecting wire.

[0011] Preferably, the outer side of the baffle is flush with the outer side of the connecting pipe.

[0012] The beneficial effects of this utility model are: (1) This utility model has a reasonable and simple structure, low production cost, convenient installation, and complete functions. The core protective component can be bent and adjusted with slight movement at the connection, while reducing the direct impact of external force on the internal connection part. It can also provide deformation space when bending, avoid damage due to excessive bending, and enhance the overall structural stability.

[0013] (2) The present invention uses symmetrically arranged fixing parts to fix the protective parts, and the cooperation between the fixing parts can achieve a firm clamping of the connection parts, which not only limits the relevant parts, but also ensures the external flatness and avoids the protruding structure from affecting the use.

[0014] (3) By setting an anti-slip structure on the outside of the relevant components, this utility model facilitates the operator to tighten or loosen the components, improves the ease of operation, and ultimately enables the entire protective device to be stably installed at the connection point, forming a comprehensive protective structure.

Detailed Implementation

[0018] like Figure 1 As shown, this specific embodiment adopts the following technical solution: a protective device at the connection between the ultrasonic probe and the connecting wire, including a protective tube 1, a spring 2, an outer spiral groove 3, an inner spiral groove 4, a first retainer 5, and a second retainer 6; the spring 2 is located inside the wall of the protective tube 1, and the protective tube 1 is a flexible tube; the outer spiral groove 3 is located on the outer side of the center between the pitches of the spring 2, and the outer spiral groove 3 is opened on the outer wall of the protective tube 1; the inner spiral groove 4 is located on the inner side of the center between the pitches of the spring 2, and the inner spiral groove 4 is opened on the inner wall of the protective tube 1; the left side of the first retainer 5 is connected to the right side of the protective tube 1; the right side of the second retainer 6 is connected to the left side of the protective tube 1.

[0019] like Figure 2As shown, the second fixing device 6 has the same structure as the first fixing device 5 and is arranged symmetrically. The specific structure of the first fixing device 5 includes a connecting pipe 51, a stop pipe 52, an external thread 53, a locking pipe 54, an internal thread 55, a tightening surface 56, an inner conical hole 57, a clamping sleeve 58, an outer conical surface 59, a slot 510, and a protrusion 511. The connecting pipe 51 has a slot 510 on the inner wall of the left side, and the slot 510 is connected to the protrusion 511 on the right side of the protective pipe 1. The connecting pipe 51 has an inner conical hole 57 that is smaller on the left and larger on the right. The external thread 53 is located on the outside of the right side of the connecting pipe 51; the locking pipe 54 has an internal thread 55 inside, and the internal thread 55 is connected to the external thread 53; the locking pipe 54 has a tightening surface 56 on the right side inside; the left side of the stop pipe 52 is fixedly connected to the left side of the connecting pipe 51, and the right side of the stop pipe 52 is connected to the left side of the locking pipe 54; the clamping sleeve 58 has an outer conical surface 59 that is smaller on the left and larger on the right, and the outer conical surfaces 59 are connected to each other; the right side of the clamping sleeve 58 is connected to the tightening surface 56.

[0020] The locking tube 54 has anti-slip texture on the outside of its right side; the inside of the clamping sleeve 58 matches the outside of the connection point of the ultrasonic probe or the outside of the connecting line; the outside of the baffle tube 52 is flush with the outside of the connecting tube 51.

[0021] The utility model is used as follows: It features a reasonable and simple structure, low production cost, convenient installation, and complete functions. Firstly, the protective tube 1, as the core protective component, has a spring 2 inside its wall in a naturally extended state, providing elastic support. This allows it to bend and adjust with slight movements at the connection point, while also reducing the direct impact of external forces on the internal connection parts through its own toughness. The outer spiral groove 3 and inner spiral groove 4 of the protective tube 1 are located on the outer and inner sides of the center between the pitches of the spring 2, respectively. When the protective tube 1 bends, these two spiral grooves provide a certain deformation space, preventing damage to the protective tube 1 due to excessive bending, and also enhancing the strength of the protective tube 1. The overall structure is stable. Fixer 1 5 and Fixer 2 6 are symmetrically arranged and connected to the right and left sides of the protective tube 1, respectively. Together, they fix the protective tube 1 in the appropriate position of the ultrasonic probe and the connecting wire. Taking Fixer 1 5 as an example, the groove 510 on the inner wall of the left side of its connecting tube 51 tightly engages with the protrusion 511 on the right side of the protective tube 1, thereby fixing the connecting tube 51 and the protective tube 1 and ensuring a stable connection. The inner conical hole 57 of the connecting tube 51, which is smaller on the left and larger on the right, fits against the outer conical surface 59 of the clamping sleeve 58, which is smaller on the left and larger on the right. When the locking tube 54 is tightened through the internal thread 55 and the external thread 53 on the right side of the connecting tube 51, the inner right side of the locking tube 54... The top tightening surface 56 will gradually press against the right side of the clamping sleeve 58. As the locking tube 54 is continuously tightened, the outer conical surface 59 of the clamping sleeve 58 moves to the left along the inner conical hole 57 of the connecting tube 51 under the thrust of the top tightening surface 56. Due to the tapered design of the inner conical hole 57 and the outer conical surface 59, the clamping sleeve 58 will gradually shrink and then tightly wrap around the outside of the ultrasonic probe connection or the outside of the connecting wire (depending on the installation position of the first fixture 5 and the second fixture 6), thus achieving a firm clamping of the connection part. The left side of the baffle tube 52 is fixedly connected to the left side of the connecting tube 51, and its right side is connected to the left side of the locking tube 54. The outside of the baffle tube 52 is connected to the outside of the connecting tube 51. The two parts are flush, which not only limits the left side of the locking tube 54, but also ensures the flatness of the outside of the fixing device 1 5, avoiding the presence of protruding structures that may affect its use. The anti-slip texture on the right side of the locking tube 54 makes it easy for operators to tighten or loosen the locking tube 54, improving the ease of operation. The fixing device 2 6 has the same structure as the fixing device 1 5. Its connecting tube, stop tube, external thread, locking tube, internal thread, top tightening surface, inner conical hole, clamping sleeve, outer conical surface, groove and protrusion, etc., are used in the same way to fix the left side of the protective tube 1 to the corresponding ultrasonic probe or connecting line. Finally, the entire protective device is stably installed at the connection between the ultrasonic probe and the connecting line, forming a comprehensive protective structure.
