Description

Technical Field

[0001] This application relates to the field of medical device technology, and more particularly to a medical probe and its sheath connection structure. Background Technology

[0002] With the continuous development of medical technology, medical ultrasound diagnostic technology has been widely used in clinical diagnosis due to its non-invasiveness, convenience, and high efficiency. During ultrasound diagnosis, the medical ultrasound probe, as a crucial front-end component that directly contacts the human body, requires a high degree of sealing and strict disinfection before and after operation.

[0003] Currently, medical ultrasound probes use adhesive to bond the outer shell and lens, as well as the outer shell, cable, and cable sheath. This ensures a secure connection while maintaining the probe's seal. However, bonding the outer shell, cable, and cable sheath, in particular, often requires two separate processes, which is time-consuming. For example, when using silicone adhesive, room temperature drying is typically required, with each bonding session taking approximately 48 hours to cure. Furthermore, once bonded, the outer shell, cable, and cable sheath are difficult to disassemble, making it difficult to remove the cable sheath and potentially damaging both the sheath and cable, hindering subsequent maintenance and repair.

[0004] Therefore, how to improve the technical defects existing in the prior art has always been a problem that ordinary people skilled in the art need to solve. Utility Model Content

[0005] The purpose of this application is to provide a medical probe and its sheath connection structure, which can ensure the sealing of the medical probe while enabling the sheath to be removed without damage, thus facilitating the maintenance and repair of the medical probe in the future.

[0006] The technical solution provided by this utility model is as follows:

[0007] A wire sheath connection structure suitable for medical probes, comprising:

[0008] Housing, cable sheath, and cable;

[0009] The housing has a tail end, through which the cable passes and exits; a cable sheath is fitted onto the tail end and covers the portion of the cable near the tail end to protect the cable.

[0010] Among them, the sheath and the tail end are interference fit, and the sheath and the cable are interference fit.

[0011] In some embodiments, the cable sheath includes a fitting and an adhesive-coated part;

[0012] One end of the rubber-coated part is fitted onto the outside of the fitting part, and the other end of the rubber-coated part is fitted onto the outside of the cable and has an interference fit with the cable; the fitting part is inserted into the tail end, and the rubber-coated part outside the fitting part has an interference fit with the tail end.

[0013] The outer wall of the fitting is provided with at least one protruding stop, which is embedded in the rubber-coated part to prevent the fitting and the rubber-coated part from separating.

[0014] In some embodiments, the overmolded part is injection molded onto the end of the insert that is furthest from the tail end.

[0015] In some embodiments, the tail end has an internal mounting hole for the wire sheath to pass through. The mounting hole has a frustum structure, with a large end and a small end. The large end is located at the end of the tail end and is used for the wire sheath to pass through the mounting hole. The outer contour of the rubber-coated part fitted onto one end of the fitting part has a frustum structure to fit the mounting hole.

[0016] In some embodiments, an annular boss is provided inside the tail end at the small end, one end of the fitting extends out of the rubber-coated part, and the end of the fitting extending out of the rubber-coated part is provided with at least one lug.

[0017] The inner wall of the annular boss has at least one slot, which is opposite to the lug, so that the lug can pass through and abut against the end of the annular boss away from the large end, so as to prevent the cable sleeve from detaching from the tail end.

[0018] In some embodiments, the annular boss has at least one slot at the end away from the large end, and the slot is opposite to the lug to accommodate the lug.

[0019] In some embodiments, the slots and grooves are opposite each other, and a guide is provided between the opposite slots and grooves. The guide is used to guide the lug that passes through the groove into the slot.

[0020] There is a height difference between the guide end face of the guide part and the bottom of the slot, so as to prevent the lug located in the slot from disengaging from the slot.

[0021] In some embodiments, the annular boss has a stop on the side of the slot away from the opposite slot to prevent the lug located in the slot from disengaging from the slot.

[0022] In some embodiments, the number of protruding stops is two; and / or the number of lugs is three, and the three lugs are evenly spaced.

[0023] This application also provides a medical probe, including the sheath connection structure provided in any of the above embodiments.

[0024] The technical advantages of this application are as follows:

[0025] 1. In this application, the cable sheath and the housing, as well as the cable sheath and the cable, are connected by an interference fit. This achieves assembly while also providing a waterproof seal, eliminating the need for adhesive bonding, saving assembly time and simplifying operation. Furthermore, the interference fit of the cable sheath, housing, and cable makes disassembly easier than adhesive bonding. Users only need to apply a certain amount of external force to remove the cable sheath and cable without damaging the end of the housing, facilitating future maintenance and repair of the medical probe.

[0026] 2. In this application, the cable sheath includes an insulated part and an insert part. The insulated part is elastic, which makes it easier to achieve a compression interference fit between the cable sheath and the tail end of the housing and the cable, and will not damage the parts during disassembly and assembly. The insert part can provide support for the interference fit between the insulated part and the tail end of the housing, thereby ensuring the connection strength between the cable sheath and the tail end of the housing. The structure is reasonable and highly practical.

[0027] 3. In this application, the inner part of the tail end of the housing is also provided with an annular boss, and a slot is opened on the annular boss. During assembly, the lug on the fitting can be aligned with the slot first. After the lug passes through, the cable protector can be rotated so that the lug can be locked in place on the annular boss. In this way, the housing and the cable protector can be prevented from separating, the connection strength is better, and if disassembly and maintenance are required, the user only needs to push the cable protector inward and rotate it so that the lug is aligned with the slot to pull out the cable protector. The operation is convenient and will not damage the parts. Attached Figure Description

For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0039] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0040] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0041] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various components of this application are relative rather than absolute. These descriptions are appropriate when these components are in the positions shown in the drawings. If the description of the positions of these components changes, these directional indications also change accordingly.

[0043] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] Currently, the housing tail end, cable sheath, and cable in medical probes are mostly fixed and assembled by adhesive bonding. This method is time-consuming and can easily damage parts if disassembly and repair are required later. It is also difficult to remove the cable sheath and cable without damaging the housing tail end, resulting in significant losses.

[0045] For this, see Figure 1 This application provides a wire sheath 200 connection structure suitable for medical probes. It can achieve non-destructive removal of the wire sheath 200 while ensuring the sealing of the medical probe, which facilitates the maintenance and repair of the medical probe in the future.

[0046] In one specific embodiment, the cable sheath 200 connection structure includes a housing, a cable sheath 200, and a cable 300. The housing has a tail end 100, and the cable 300 passes through the housing and exits through the tail end 100. The cable sheath 200 is fitted onto the tail end 100 and covers the portion of the cable 300 near the tail end 100 to protect the cable 300. The cable sheath 200 and the tail end 100, as well as the cable sheath 200 and the cable 300, are both interference-fitted.

[0047] In this embodiment, an interference fit is used to achieve a fixed connection between the cable sheath 200, the housing, and the cable 300, while also providing a good waterproof seal. During assembly, the user only needs to pass the cable 300 through the cable sheath 200 and place the cable sheath 200 on the tail end 100 of the housing to secure these three parts. Compared to traditional adhesive methods, this eliminates the need for step-by-step operations and waiting for the adhesive to dry, saving time and facilitating mass production and assembly of medical probes. Furthermore, the interference fit of the cable sheath 200, housing, and cable 300 makes disassembly easier than adhesive fixation. The user only needs to apply a certain amount of external force to remove the cable sheath 200 and cable 300 without damaging the tail end 100 of the housing, facilitating future maintenance and repair of the medical probe. The operation is convenient and quick.

[0048] Specifically, see Figure 1 and Figure 4The cable sleeve 200 includes a fitting 210 and a coating 220. One end of the coating 220 is fitted outside the fitting 210, and the other end of the coating 220 (i.e. the end away from the fitting 210) is fitted outside the cable 300 and is interference-fitted with the cable 300. The fitting 210 is inserted inside the tail end 100, and the coating 220 outside the fitting 210 is interference-fitted with the tail end 100.

[0049] In this embodiment, the cable 300 is covered by an insulated part 220, which provides better protection for the cable 300. The insulated part 220 also has a certain degree of elasticity, allowing for a compression fit between the cable sheath 200 and the cable 300 without increasing assembly difficulty. When the cable sheath 200 is fitted over the cable 300, the insulated part 220 adheres tightly to the outer wall of the cable 300, resulting in significant friction. Disassembly can only be achieved by pulling the cable 300 or the cable sheath 200 with sufficient force. Conversely, the cable sheath 200 and the tail end 100 of the housing are compressed and fitted together via the inner hole of the tail end 100 and the fitting 210 covered by the insulated part 220. The fitting 210 provides support for the interference fit between the insulated part 220 and the tail end 100 of the housing, thereby ensuring the connection strength between the cable sheath 200 and the tail end 100 of the housing.

[0050] More importantly, due to the design of the rubber-coated part 220, users will not scratch the housing or cable 300 when disassembling or assembling the cable sleeve 200, housing, and cable 300, which helps to achieve non-destructive disassembly. The structure is more reasonable and practical.

[0051] In a preferred embodiment, see Figure 4 The outer wall of the fitting 210 is provided with at least one protruding stop 211, which is embedded in the rubber-coated part 220. This protruding stop 211 can prevent the fitting 210 and the rubber-coated part 220 from separating, so that the rubber-coated part 220 and the fitting 210 can be integrated as a whole and interference-fitted with the housing and the cable 300. Preferably, there are two protruding stops 211 for better structural stability.

[0052] Among them, the insert 210 can be processed as an independent part first, and then the rubber-coated part 220 can be processed at the end of the insert 210 away from the tail end 100 of the shell by injection molding. In this way, the rubber-coated part 220 can be firmly formed on the insert 210 and form an integral part with it, which is not easy to fall off.

[0053] Further, see Figure 1 , Figure 2 and Figure 4The tail end 100 has an internal mounting hole 110 for the cable sheath 200 to pass through, which is the inner hole of the tail end 100. The mounting hole 110 is preferably frustum-shaped, having a large end and a small end, with the large end located at the end of the tail end 100 for the cable sheath 200 to pass through. At this time, the outer contour of the rubber-coated part 220, which is fitted onto one end of the fitting part 210, is also frustum-shaped to fit the mounting hole 110.

[0054] In this embodiment, by setting the assembly hole 110 as a frustum structure with the larger end facing outward, it is more conducive to the insertion of the cable sleeve 200 during assembly. At this time, the hole wall of the assembly hole 110 can play a guiding role, realizing the quick alignment of the cable sleeve 200, making installation convenient and quick. Furthermore, by setting the outer contour of the rubber-coated part 220, which is fitted onto one end of the fitting part 210, as a frustum structure, it is beneficial to ensure a tight fit between the cable sleeve 200 and the hole wall of the assembly hole 110, resulting in greater friction between the two. This improves the connection strength between the cable sleeve 200 and the tail end 100 of the housing, requiring the user to pull the tail end 100 of the housing or the cable sleeve 200 with sufficient force to disassemble them.

[0055] Preferably, see Figure 1 and Figures 3 to 5 The tail end 100 has an annular boss 120 at the small end. One end of the fitting 210 extends out of the rubber-coated part 220, and the end of the fitting 210 extending out of the rubber-coated part 220 has at least one lug 212. The inner sidewall of the annular boss 120 has at least one slot 121, which is opposite to the lug 212. The slot 121 is used to allow the lug 212 to pass through and abut against the end of the annular boss 120 away from the large end, so as to prevent the cable sleeve 200 from detaching from the tail end 100.

[0056] In this embodiment, a limiting structure, namely an annular boss 120 and a lug 212, is provided inside the tail end 100 and between the fitting 210. The limiting and locking mechanism between the annular boss 120 and the lug 212 prevents the tail end 100 from separating from the fitting 210, improving the connection stability between the housing and the cable sleeve 200. Furthermore, this embodiment also has a slot 121 on the annular boss 120. During assembly, the user can first align the lug 212 on the fitting 210 with the slot 121. After the lug 212 passes through, the cable sleeve 200 is rotated so that the lug 212 can be locked into the annular boss 120. This effectively prevents the housing from separating from the cable sleeve 200, resulting in better connection strength. Moreover, if disassembly and maintenance are required, the user only needs to push the cable sleeve 200 inward and rotate it to align the lug 212 with the slot 121 to pull out the cable sleeve 200. The operation is convenient, simple, and less likely to damage the parts.

[0057] Of course, in actual production, the annular boss 120 and the lug 212 can also have a slightly elastic structure. In this case, the slot 121 does not need to be opened on the annular boss 120. The user only needs to use external force to press the lug 212 into the annular boss 120 so that it abuts against the side of the annular boss 120 away from the large end, thereby achieving the connection and fixation between the shell and the cable sleeve 200. When disassembling, the user can grasp the cable sleeve 200 and forcefully pull the lug 212 out of the annular boss 120 to achieve the disassembly between the shell and the cable sleeve 200. This is not limited and is within the protection scope of this application. However, considering that the operability of this structure is worse than opening a slot 121 on the annular boss 120, this application preferably adopts a structure in which a slot 121 is opened on the annular boss 120 for the lug 212 to pass through.

[0058] Further, see Figure 3 and Figure 4 At least one slot 122 is provided at the end of the annular boss 120 away from the large end. The slot 122 is opposite to the lug 212 and is used to accommodate the lug 212. The slots 122 at both ends of the annular boss 120 in the circumferential direction can limit the lug 212, thereby reducing the risk of the lug 212 accidentally coming out of the slot 121 due to the rotation of the cable sleeve 200 relative to the tail end 100 of the housing, and improving the connection strength and stability.

[0059] Since the slots 122 and lugs 212 are one-to-one, and the slots 121 and lugs 212 are also one-to-one, there are also one-to-one corresponding slots 122 and slots 121 in the slots 122 and slots 121. Specifically, taking the number of lugs 212 as three, and the three lugs 212 being evenly spaced, the number of slots 122 and slots 121 in this embodiment is also three. The three lugs 212 can pass through the three slots 121 to the side of the annular boss 120 away from the large end. After the user rotates the fitting 210, the three lugs 212 can enter the three slots 122 respectively. At this time, the slot 121 through which each lug 212 passes and the slot 122 where it is placed can be understood as corresponding slots 122 and slots 121.

[0060] As a preferred option, see Figure 3A guide portion 123 is provided between the corresponding slot 122 and the slot 121. The guide portion 123 is used to guide the lug 212 passing through the slot 121 into the slot 122. There should be a height difference between the guide end face of the guide portion 123 and the bottom of the slot 122, which can be used to prevent the lug 212 already located in the slot 122 from detaching from the slot 122. The side wall of the slot 122 corresponding to the guide portion 123 is steep, increasing the difficulty for the lug 212 to detach from the slot 122. Conversely, a stop 124 can also be provided on the side of the slot 122 away from the corresponding slot 121 of the annular boss 120, which can also be used to prevent the lug 212 located in the slot 122 from detaching from the slot 122.

[0061] Furthermore, the end of the baffle 124 furthest from the corresponding slot 122 extends to the edge of another slot 121, and the height of the baffle 124 is also higher than that of the guide portion 123. In this case, the baffle 124 also serves to guide the user to the correct rotation direction. For example, after the user inserts the lug 212 into the slot 121, if it is not rotated towards the guide portion 123, the lug 212 will be blocked by another non-corresponding baffle 124, and the user will feel resistance. At this time, the user can rotate the cable sleeve 200 in the opposite direction to allow the lug 212 to enter the corresponding slot 122 along the guide portion 123. Conversely, when the user pushes the lug 212 inward to disengage it from the slot 122, if it is not rotated towards the guide portion 123, the lug 212 will be blocked by the corresponding baffle 124, and the user will feel resistance. At this time, the user can rotate the cable sleeve 200 in the opposite direction to allow the lug 212 to leave the corresponding slot 121 along the guide portion 123. In addition, the baffle 124 can also prompt the user whether it has been rotated to the slot 121 during disassembly. If it has been rotated to the correct position, the lug 212 will be blocked by another non-corresponding baffle 124 on the side of the slot 121. After the user feels the resistance, he / she can directly pull out the cable sleeve 200.

[0062] Specifically, take the example of inserting and then rotating counterclockwise to fix it.

[0063] During assembly, the user can first roughly align the three lugs 212 of the cable protector 200 with the three slots 121 at the tail of the housing, and then slowly push the cable protector 200 into the tail end 100 of the housing until it can no longer be pushed. At this point, the edge of the lug 212 abuts against the annular boss 120. Next, by slightly rotating and pushing back and forth, the lug 212 can fall into the corresponding slot 121. At this time, rotating the cable protector 200 counterclockwise will allow the lug 212 to slide along the corresponding guide 123 into the corresponding slot 122. Since the guide 123 and the corresponding stop 124 are both much higher than the bottom of the slot 122 and are both steep surfaces, the lug 212 can no longer be rotated.

[0064] Furthermore, since the bottom plane of the slot 122 and the height of the annular boss 120 are pre-calculated according to the interference fit required at the end of the mounting hole 110 and the cable sleeve 200, the mounting hole 110 and the cable sleeve 200 are in an interference fit state, thereby enabling the cable sleeve 200 to achieve a sealed and secure connection with the tail end 100 of the housing. Conversely, the inner diameter of the other end of the cable sleeve 200 and the outer diameter of the cable 300 are also pre-designed according to the interference fit, and the cable sleeve 200 and the cable 300 are also in a sealed and secure connection state.

[0065] During disassembly, the user first holds the portion of the cable sheath 200 near the tail end 100 of the housing and pushes it forcefully towards the housing, causing the lug 212 of the cable sheath 200 to move in the direction of the push. When the force is sufficient, the lug 212 will rise above the height of the guide portion 123. At this point, the user rotates the cable sheath 200 clockwise until it can no longer rotate. In this state, the lug 212 is blocked by another non-corresponding stop 124 on the side of the slot 121, indicating to the user that it has been rotated to the correct position. The user then removes the push force and instead uses one hand to hold the cable 300 and the other hand to hold the cable sheath 200, pulling the cable sheath 200 away from the housing to pull it out of the tail end 100 of the housing.

[0066] This application also provides a medical probe, including the wire sheath 200 connection structure provided in any of the above embodiments. While ensuring the sealing of the medical probe, it also enables the wire sheath 200 to be removed without damage, which facilitates the maintenance and repair of the medical probe in the future.

[0067] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0068] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
