Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to needles, clamping components, and needle components. Background Technology

[0002] Acupuncture needles consist of a needle body and a needle handle. The needle body is inserted into the patient's body to perform acupuncture, while the needle handle is located outside the patient's body, making it easy for the doctor to hold the needle for insertion and removal.

[0003] As is well known, acupuncture can treat head ailments such as insomnia and headaches. In clinical practice, acupuncture needles are inserted into acupoints on the head for treatment. When a patient has insomnia, the needles need to be left in overnight and removed the next day. However, during acupuncture, the needle handle is straight and protrudes significantly beyond the patient's body. While this makes it easier for the doctor to hold the needle, it presents a challenge. The patient must avoid the needle handle while lying down, and their sleeping position should remain unchanged to prevent external force from acting on the needle handle during turning over, which could cause a foreign body sensation and affect sleep quality. Furthermore, changes in the needle handle's position can shift the position of the needle itself inside the body, potentially causing injury and impacting the patient's health. Therefore, leaving the needles in overnight is difficult to perform. Utility Model Content

[0004] In view of this, the present invention provides a needle, a clamping assembly, and a needle assembly to solve the problem that when patients are lying down during the overnight needle retention process, they need to avoid the needle handle, and their sleeping posture cannot be adjusted during sleep, making it difficult to retain needles overnight.

[0005] In a first aspect, this utility model provides a needle, comprising:

[0006] The needle body includes a main body and a fixing unit. One end of the main body is connected to the fixing unit, and the other end of the main body is the needle tip. Along the axis perpendicular to the needle body, the fixing unit is larger than the main body. The fixing unit is used to fit against the patient's skin surface to avoid giving the patient a foreign body sensation.

[0007] Beneficial effects: By setting up a fixing unit, external force holds the fixing unit and drives the main body to be inserted into the patient's body. At this time, the fixing unit conforms to the patient's skin surface, which can avoid the patient experiencing a foreign body sensation, thereby improving the comfort of acupuncture. It can also ensure that the needles are left on the patient's head overnight and will not change position with changes in the patient's posture during sleep, avoiding the possibility of puncture injury. This improves the feasibility of leaving needles in overnight.

[0008] In one optional embodiment, a cross-section is taken along the axis perpendicular to the needle body, the fixing unit is polygonal, and the corners of the fixing unit are arc-shaped;

[0009] Alternatively, a cross-section can be made along the axis perpendicular to the needle body, and the fixing unit can be a closed shape composed of arcs.

[0010] Beneficial effects: By defining the cross-section along the axis perpendicular to the needle body and fixing the specific shape of the unit, the occurrence of sharp parts in the fixing unit that could injure the patient can be avoided, thereby improving the protection of the patient.

[0011] In one alternative embodiment, the fixing unit is circular, with a cross-section taken along the axis perpendicular to the needle body.

[0012] Beneficial effects: By defining the cross-section along the axis perpendicular to the needle body and making the fixing unit circular, the smoothness of the fixing unit can be improved, thereby enhancing the protection of the patient.

[0013] Secondly, this utility model also provides a clamping assembly for clamping the aforementioned needle, the clamping assembly comprising:

[0014] First clamping part;

[0015] The second clamping part has one end hinged to one end of the first clamping part, and the hinged position forms a hinge end. The other end of the second clamping part and the other end of the first clamping part are used to clamp the fixing unit.

[0016] The fixing part is used to fix the clamping state of the first clamping part and the second clamping part;

[0017] An adjustment unit is provided at the other end of the first clamping part and / or the other end of the second clamping part, and the adjustment unit is provided on the side where the first clamping part and the second clamping part are close to each other. The adjustment unit is detachably connected to the fixing unit and is used to clamp the fixing unit.

[0018] Beneficial effects: By setting up clamping components to hold and fix the needles, it can be ensured that the doctor's hand will not touch the needle body, thus preventing bacteria from entering the patient's body with the needle and affecting the patient's health, thereby achieving the technical effect of improving the hygiene of acupuncture.

[0019] In one alternative embodiment, the shape of the adjustment unit is the same as the shape of at least a portion of the fixing unit;

[0020] And / or, the adjustment unit is provided.

[0021] Beneficial effect: By limiting the shape of the adjustment unit to be the same as the shape of at least part of the fixed unit, the adjustment unit and the fixed unit are fitted together, thereby achieving the technical effect of improving the stability of the fixed unit clamping.

[0022] The device is equipped with a limited adjustment unit, which enables the clamping and fixing of the needle.

[0023] In one optional embodiment, when the clamping assembly clamps the needle, the adjusting unit is provided with the fixing unit, and the body is located outside the clamping assembly.

[0024] Beneficial effects: When the clamping assembly holds the needle, the fixing unit is located within the adjusting unit, and the main body is located outside the clamping assembly. This avoids contact between the doctor's hand and the needle body, thus preventing compromised hygiene during acupuncture and enhancing patient protection.

[0025] In one optional embodiment, the adjustment unit is provided in multiple ways. The adjustment unit includes a protrusion and a groove. The protrusion and the groove face opposite directions. Adjacent protrusions and grooves are connected so that the protrusions and grooves are alternately arranged in sequence. When the fixing unit is driven by an external force, the fixing unit moves along the length direction of the adjustment unit.

[0026] Beneficial effects: By defining multiple adjustment units and their structure, not only can the fixing unit be fixed using the adjustment units, but the dimensions of the fixing units within the adjustment units can also be determined as needed, thereby improving the ease of use of the clamping assembly.

[0027] In one optional embodiment, the fixing part includes:

[0028] An elastic unit is provided at the hinge end, one end of the elastic unit is connected to the first clamping part, and the other end of the elastic unit is connected to the second clamping part.

[0029] Beneficial effects: By incorporating the elastic unit, the first and second clamping parts are always in a clamping state. That is, when an external force drives the other ends of the first and second clamping parts away from each other, the elastic unit is in a state of elastic deformation. When the external force is removed, under the elastic force of the elastic unit, the other ends of the first and second clamping parts move closer together to clamp the fixed unit. This not only improves the ease of clamping the fixed unit but also makes the clamping assembly suitable for fixed units of various sizes, thereby enhancing the adaptability of the clamping assembly to fixed units of different sizes.

[0030] Thirdly, this utility model also provides a needle assembly, comprising:

[0031] The needles described above;

[0032] The clamping assembly described above is detachably connected to the needle. The needle has a usage state in which the fixing unit is located inside the clamping assembly and the body is located outside the clamping assembly, and a storage state in which the needle is located inside the clamping assembly.

[0033] Beneficial effects: When the needle is in its stored state, and no needling operation is being performed on the patient, the entire needle body is positioned between the first and second clamping parts. This avoids the needle body being outside the clamping components, thus preventing increased contact with bacteria and improving the hygiene of acupuncture. When the needle body is in use, external force can drive the fixing unit to move along the length of the adjusting unit, moving the needle body outside the clamping components for easier needling operation on the patient.

[0034] In one alternative implementation, the fixing unit is an elastic element.

[0035] Beneficial effects: By limiting the fixing unit to an elastic element, the deformation capacity of the fixing unit when passing through the protrusion can be improved, and the difficulty of the fixing unit moving along the axis of the needle body can be reduced, thereby achieving the technical effect of improving the ease of movement of the fixing unit along the adjustment unit.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0046] According to an embodiment of the present invention, in one aspect, a needle is provided, comprising:

[0047] The needle body includes a main body 1 and a fixing unit 2. One end of the main body 1 is connected to the fixing unit 2, and the other end of the main body 1 is the needle tip. Along the axis perpendicular to the needle body, the size of the fixing unit 2 is larger than the size of the main body 1. The fixing unit 2 is used to fit against the patient's skin surface to avoid giving the patient a foreign body sensation.

[0048] In the needle of this embodiment, by setting a fixing unit 2, external force is used to hold the fixing unit 2 and drive the body 1 to be inserted into the patient's body. At this time, the fixing unit 2 is in contact with the patient's skin surface, which can avoid the fixing unit 2 giving the patient a foreign body sensation, thereby achieving the technical effect of improving acupuncture comfort. It can also ensure that the needle is left on the patient's head overnight and will not change position with the patient's posture during sleep, avoiding the possibility of puncturing the patient, thereby achieving the technical effect of improving the feasibility of leaving the needle in overnight.

[0049] Among them, the direction along the axis perpendicular to the needle body is... Figure 1 As shown in the horizontal direction, and with the size of the fixing unit 2 slightly larger than the size of the main body 1, it is possible to avoid the fixing unit 2 causing the patient to feel a foreign body sensation.

[0050] In addition, combined Figure 1 As shown, in this embodiment, the fixing unit 2 is a closed shape composed of arcs, with a cross-section taken along the axis perpendicular to the needle body. This avoids the possibility of sharp parts in the fixing unit 2 causing injury to the patient, thereby improving the technical effect of patient protection.

[0051] Preferably, the fixing unit 2 is circular in cross-section along the axis perpendicular to the needle body. This improves the smoothness of the fixing unit 2, thereby enhancing the protection for the patient.

[0052] As an alternative implementation, the fixing unit 2 can be polygonal with a cross-section along the axis perpendicular to the needle body, and the corners of the fixing unit 2 can be arc-shaped.

[0053] Of course, in other embodiments, depending on the design of the clamping assembly, the shape of the fixing unit 2 is adjusted by making a cross-section along the axis perpendicular to the needle body.

[0054] Furthermore, in this embodiment, the surface of the fixation unit 2 may be provided with a silicone layer, which can achieve the technical effect of improving the comfort of the patient's skin surface in contact with the fixation unit 2. As an alternative implementation, the surface of the fixation unit 2 may not be provided with a silicone layer.

[0055] In practical use, the fixing unit 2 can be a color, such as red, to enhance the warning effect and facilitate the doctor's quick location of the needle when removing it. As an alternative implementation, the fixing unit 2 can also be the same color as the main body 1, or it can be a different color.

[0056] On the other hand, a clamping assembly is provided for clamping the needle of this embodiment. The clamping assembly includes:

[0057] First clamping part 3;

[0058] The second clamping part 4 has one end hinged to one end of the first clamping part 3, and the hinged position forms a hinge end. The other end of the second clamping part 4 and the other end of the first clamping part 3 are used to clamp and fix the unit 2.

[0059] The fixing part is used to fix the clamping state of the first clamping part 3 and the second clamping part 4;

[0060] An adjustment unit 6 is provided at the other end of the first clamping part 3 and / or the other end of the second clamping part 4. The adjustment unit 6 is provided on the side where the first clamping part 3 and the second clamping part 4 are close to each other. The adjustment unit 6 is detachably connected to the fixing unit 2 and is used to clamp the fixing unit 2.

[0061] In the clamping assembly of this embodiment, the needle is placed between the first clamping part 3 and the second clamping part 4, and the first clamping part 3 and the second clamping part 4 are clamped by the fixing part to facilitate the doctor's operation of the needle. Of course, in other embodiments, the fixing unit 2 can be held by hand to perform acupuncture on the patient. Compared with other embodiments, this embodiment, by setting up a clamping assembly, can ensure that the doctor's hand will not touch the needle body, avoiding bacteria from entering the patient's body with the needle body 1 and affecting the patient's health, thereby achieving the technical effect of improving the hygiene of acupuncture.

[0062] In this embodiment, the adjustment unit 6 is located at the other end of the first clamping part 3. Alternatively, the adjustment unit 6 may be located at the other end of the second clamping part 4, or simultaneously at the other ends of both the first clamping part 3 and the second clamping part 4. Further, the side of the first clamping part 3 and the second clamping part 4 that is close to each other refers to the side where the first clamping part 3 is combined with... Figure 1 As shown on the right side, the second clamping part 4 is engaged. Figure 1 The left side is shown.

[0063] Preferably, combined with Figure 2 As shown, the fixing part includes:

[0064] The elastic unit 5 is located at the hinge end. One end of the elastic unit 5 is connected to the first clamping part 3, and the other end of the elastic unit 5 is connected to the second clamping part 4.

[0065] By incorporating the elastic unit 5, the first clamping part 3 and the second clamping part 4 are always in a clamping state. That is, when an external force drives the other ends of the first clamping part 3 and the second clamping part 4 away from each other, the elastic unit 5 is in a state of elastic deformation. When the external force is removed, under the elastic force of the elastic unit 5, the other ends of the first clamping part 3 and the second clamping part 4 move closer together to clamp the fixing unit 2. Based on this, the clamping assembly can be applied to fixing units 2 of various sizes, thereby achieving the technical effect of improving the adaptability of the clamping assembly to fixing units 2 of different sizes.

[0066] Specifically, the doctor holds one end of the first clamping part 3 and one end of the second clamping part 4, and drives one end of the first clamping part 3 and one end of the second clamping part 4 to move closer to each other, so that the other end of the first clamping part 3 and the other end of the second clamping part 4 move further apart. The fixing unit 2 is placed in the adjusting unit 6. When the doctor releases his hand, under the drive of the elastic unit 5, the adjusting unit 6 and the second clamping part 4 cooperate to stably clamp the needle.

[0067] In this embodiment, the elastic element 5 can be a spring. In other embodiments, the type of elastic element 5 may be adjusted depending on the design of the clamping assembly.

[0068] Of course, in other embodiments, depending on the design of the clamping assembly, the fixing part does not include the elastic unit 5. When the fixing unit 2 is located within the adjusting unit 6, the position between the first clamping part 3 and the second clamping part 4 can be fixed by other structures, such as a clamp. Compared to other embodiments, this embodiment does not require manual clamping. When the external force on one end of the first clamping part 3 and one end of the second clamping part 4 is removed, the first clamping part 3 and the second clamping part 4 can automatically clamp the fixing unit 2 under the elastic force of the elastic unit 5, thereby achieving the technical effect of improving the ease of clamping the fixing unit 2.

[0069] In addition, in this embodiment, multiple adjustment units 6 are provided. Each adjustment unit 6 includes a protrusion 601 and a groove 602. The orientation of the protrusion 601 and the orientation of the groove 602 are opposite. Adjacent protrusions 601 and grooves 602 are connected so that the protrusions 601 and grooves 602 are alternately arranged in sequence to form a sawtooth structure. When the external force drives the fixing unit 2, the fixing unit 2 moves along the axial direction of the needle body.

[0070] Based on this, not only can the fixing unit 2 be fixed by adjusting the unit 6, but the size of the fixing unit 2 within the adjusting unit 6 can also be determined as needed, thereby achieving the technical effect of improving the ease of use of the clamping assembly.

[0071] Furthermore, combined Figure 1 and Figure 3 As shown, in this embodiment, the shape of the adjustment unit 6, namely the shape of the groove 602 and the shape of the protrusion 601, is the same as the shape of at least part of the fixing unit 2. Based on this, the adjustment unit 6 is fitted to the fixing unit 2, thereby achieving the technical effect of improving the stability of clamping the fixing unit 2.

[0072] Of course, in other embodiments, combined Figure 4As shown, an adjustment unit 6 is provided, and in this case, the adjustment unit 6 has a groove structure, which can also be used to clamp and fix the needle. Furthermore, when the clamping assembly clamps the needle, the adjustment unit 6 has a fixing unit 2 inside, and the main body 1 is located outside the clamping assembly. In this case, the adjustment unit 6 only clamps the needle to prevent the doctor's hand from contacting the needle body, thus avoiding affecting the hygiene of acupuncture and achieving the technical effect of improving patient protection.

[0073] In other embodiments, depending on the design of the clamping assembly, only one adjustment unit 6 is provided, or the shape of the adjustment unit 6 is the same as the shape of at least part of the fixing unit 2, and the adjustment unit 6 is provided.

[0074] Furthermore, in this embodiment, the clamping components are reusable, while the needles are disposable. Of course, in other embodiments, the number of clamping components can correspond one-to-one with the number of needles. Compared to other embodiments, the reusable clamping components in this embodiment reduce the number of clamping components required, thereby reducing the number of clamping components used and ultimately lowering the production cost of the clamping components.

[0075] Furthermore, a needle assembly is also provided, including:

[0076] The needles used in this embodiment;

[0077] In this embodiment, the clamping assembly is detachably connected to the needle. The needle has a working state where the fixing unit 2 is located inside the clamping assembly and the main body 1 is located outside the clamping assembly, and a stored state where the needle is located inside the clamping assembly. Therefore, when the needle is in the stored state, no acupuncture is being performed on the patient, and the entire needle body is positioned between the first clamping part 3 and the second clamping part 4. This avoids increasing the probability of contact with bacteria due to the needle body being located outside the clamping assembly, thereby improving the hygiene of acupuncture. When the needle is in the working state, the fixing unit 2 can be moved along the length direction of the adjusting unit 6 by external force, allowing the main body 1 to be moved outside the clamping assembly for acupuncture treatment.

[0078] Furthermore, the fixing unit 2 is an elastic element, such as spring steel. Based on this, the deformation capacity of the fixing unit 2 when passing the protrusion 601 can be improved, and the difficulty of the fixing unit 2 moving along the axis of the needle body can be reduced, thereby achieving the technical effect of improving the ease of movement of the fixing unit 2 along the adjustment unit 6.

[0079] Preferably, the position of the external force driving fixation unit 2 is provided with friction protrusions, which can increase the friction between the doctor's finger and the fixation unit 2, thereby achieving the technical effect of improving the stability of the driving fixation unit 2.

[0080] Of course, in other embodiments, the type of fixing unit 2 can be adjusted depending on the design of the needle assembly. Alternatively, the fixing unit 2 may be non-elastic, and friction protrusions may not be provided at the position where the external force drives the fixing unit 2.

[0081] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
