[0031] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0032] Embodiment 1

[0033] In order to facilitate puncture and subsequent treatment operations, it is necessary to hold the outer tube of the tube throughout the whole process or clamp it with surgical forceps to ensure that the outer tube can shake in a small range, so that the patient can move his body slightly and adjust to a more comfortable posture, and at the same time ensure that the outer tube will not fall naturally. The above-mentioned needle-holding process has the following problems: holding the outer tube directly with hands for a long time or indirectly holding the outer tube with surgical forceps will increase the physical burden of medical staff, causing stiffness of the arms and body of medical staff, which is not conducive to the flexible movement and treatment operations of medical staff. In addition, when the medical staff's arms shake or the patient shifts, the outer tube may shake to a large extent, causing the safety risk of wound tearing.

[0034] To solve the above problems, Figure 1 As shown, this embodiment proposes an auxiliary needle support stand, which includes a base 1, a bracket 2 and a needle support rod group 3. The base 1 is provided with an avoidance hole 11 for the outer sleeve 10 of the puncture needle to pass through. The bracket 2 is arranged on the base 1. The needle support rod group 3 is arranged on the bracket 2 and has a V-shaped limit groove 30 located above the avoidance hole 11, and the outer sleeve 10 can be movably against the inner wall of the V-shaped limit groove 30. Since the outer sleeve 10 of the puncture needle can be movably against the inner wall of the V-shaped limit groove 30, the V-shaped limit groove 30 can provide stable support for the outer sleeve 10 to prevent the outer sleeve 10 from falling down, and there is no need for manual participation in the needle support process, which reduces the physical burden of medical staff. At the same time, the V-shaped limit groove 30 can limit the swing range of the outer sleeve 10 to prevent the outer sleeve 10 from shaking too much when the patient is displaced, avoid the risk of wound tearing in the patient, and improve the stability and safety of the needle support process.

[0035] like Figure 1 As shown, the base 1 is a U-shaped base or a C-shaped base, so that the avoidance hole 11 has a first opening, and the V-shaped limiting groove 30 has a second opening in the same direction as the first opening. Since the base 1 and the needle supporting rod group 3 have openings in the same direction, the auxiliary needle supporting frame can quickly approach or move away from the outer sleeve 10 in the horizontal direction (or the radial direction of the outer sleeve 10), so that the outer sleeve 10 quickly passes through the two openings and abuts against the inner wall of the V-shaped limiting groove 30, thereby realizing the rapid installation of the auxiliary needle supporting frame.

[0036] Specifically, the base 1 is a C-shaped base, so that the avoidance hole 11 is an unclosed circular hole, and the unclosed portion of the avoidance hole 11 forms a first opening. In other embodiments, the base 1 can also be a U-shaped base or a separate non-enclosed base, which is not specifically limited here.

[0037] Furthermore, the auxiliary needle support also includes an adhesive sticker 4, and the lower end of the base 1 is bonded with the adhesive sticker 4. The base 1 and the adhesive sticker 4 are assembled by bonding, which improves the assembly efficiency. At the same time, the adhesive sticker 4 can be quickly replaced and repeatedly bonded to the patient's wound, thereby realizing the reuse of the adhesive sticker 4. The bottom surface of the adhesive sticker 4 facing away from the base 1 has an easy-to-tear film. When the auxiliary needle support needs to be used, it is only necessary to tear off the easy-to-tear film, and then bond the adhesive sticker 4 to the patient's wound where the puncture needle outer sleeve 10 is inserted. The operation is simple, convenient and quick.

[0038] Specifically, the adhesive patch 4 of this embodiment is roughly C-shaped, and at least part of the inner side edge of the adhesive patch 4 overlaps with the inner side edge of the avoidance hole 11 of the base 1 to prevent the inner side edge of the adhesive patch 4 from blocking the free swing of the outer sleeve 10. At the same time, the cross-sectional area of ​​the adhesive patch 4 is larger than the cross-sectional area of ​​the base 1, thereby increasing the contact area between the adhesive patch 4 and the patient's body surface, so as to improve the bonding strength and stability of the adhesive patch 4.

[0039] like Figure 1 As shown, the bracket 2 includes a third rod 21 and a fourth rod 22. The third rod 21 is connected to one end of the fourth rod 22 and jointly supports the needle support rod group 3. The other ends of the third rod 21 and the fourth rod 22 are spaced apart on the base 1 to form a triangular frame. By setting the bracket 2 as a triangular frame, the structural strength and stability of the bracket 2 are improved. Specifically, the bracket 2 of this embodiment has two third rods 21 and two fourth rods 22. One third rod 21, one fourth rod 22 and the base 1 together form a triangular frame, so that the bracket 2 has two triangular frames spaced apart along the circumference of the base 1, which further improves the stability and load-bearing capacity of the bracket 2. In other embodiments, the bracket 2 may also have three or more triangular frames, which are not specifically limited here.

[0040] The base 1, bracket 2, and needle support rod group 3 of this embodiment are integrally formed, which improves the processing efficiency and structural strength of the auxiliary needle support frame and helps reduce the cost of the auxiliary needle support frame. The base 1, bracket 2, and needle support rod group 3 of this embodiment are all made of resin and are integrally formed by injection molding.

[0041] like Figure 1As shown, the needle support rod group 3 includes two first rods 31, and the first ends of the two first rods 31 are connected and surrounded by a V-shaped limit groove 30. The second ends of the two first rods 31 intersect with the top ends of the corresponding triangular frames to form a whole. The outer sleeve 10 can shake slightly along the two first rods 31, which is convenient for the patient to adjust the position and posture or the medical staff to slightly adjust the position of the outer sleeve 10, which is beneficial to the treatment operation of the medical staff and can also avoid tearing of the wound. Since the first rod 31 can play a guiding and limiting role on the outer sleeve 10, it not only limits the swing range of the outer sleeve 10, but also enables the outer sleeve 10 that has shaken and displaced to return to the V-shaped bend of the V-shaped limit groove 30 under the guiding action of the first rod 31.

[0042] The angle α of the two first rods 31 of the present embodiment is 110°~150°. For example, the angle α of the two first rods 31 can be 110°, 120°, 130°, 140° or 150°, so that the angle α can be adapted to the natural swing amplitude of the outer sleeve 10. If the angle α is too small (i.e. less than 110°), for example, when α=90°, it is easy to cause the outer sleeve 10 to get stuck at the bend of the two first rods 31, causing a greater pulling sensation when the patient is displaced. If the angle α is too large (i.e. greater than 150°), for example, when α=170°, the two first rods 31 are connected to be similar to a straight rod, which is difficult to guide the outer sleeve 10, and the outer sleeve 10 is difficult to return to the V-shaped bend of the V-shaped limit groove 30 after a slight swing.

[0043] Furthermore, the first ends of the two first rods 31 are connected with a smooth transition, that is, the V-shaped bend of the V-shaped limiting groove 30 is rounded, so that the outer sleeve 10 can slide smoothly at the V-shaped bend to avoid jamming of the outer sleeve 10 during swinging.

[0044] Embodiment 2

[0045] like Figure 2 As shown, this embodiment proposes an auxiliary needle support frame. The auxiliary needle support frame of this embodiment has a substantially same structure as the auxiliary needle support frame in the first embodiment, and the main difference is that the specific structure of the needle support rod group 3 is different.

[0046] like Figure 2 and Figure 3As shown, the needle support rod group 3 of this embodiment includes two first rods 31, and the first ends of the two first rods 31 are connected and surrounded by a V-shaped limit groove 30. The outer sleeve 10 can slightly shake along the two first rods 31, which is convenient for the patient to adjust the position and posture or the medical staff to slightly adjust the position of the outer sleeve 10, which is beneficial to the treatment operation of the medical staff and can avoid tearing the wound. Since the first rod 31 can play a guiding and limiting role on the outer sleeve 10, it not only limits the swing range of the outer sleeve 10, but also allows the outer sleeve 10 that has shaken and displaced to return to the V-shaped bend of the V-shaped limit groove 30 under the guidance of the first rod 31.

[0047] The angle α between the two first rods 31 of the present embodiment is 110° to 150°. For example, the angle α between the two first rods 31 can be 110°, 120°, 130°, 140° or 150°, so that the angle α can be adapted to the natural swing amplitude of the outer sleeve 10. If the angle α is too small (i.e., less than 110°), for example, when α=90°, it is easy to cause the outer sleeve 10 to get stuck at the bend of the two first rods 31, causing a greater pulling sensation when the patient is displaced. If the angle α is too large (i.e., greater than 150°), for example, when α=170°, the two first rods 31 are close to straight rods, which makes it difficult to guide the outer sleeve 10, and the outer sleeve 10 is difficult to return to the V-shaped bend of the V-shaped limit groove 30 after a slight swing.

[0048] Furthermore, if Figure 2 and Figure 3 As shown, the needle supporting rod group 3 also includes two second rods 32, the second end of each first rod 31 is connected to one end of the second rod 32 at an angle, and the second rod 32 is tilted toward the inside of the V-shaped limiting groove 30. The second rod 32 can also play a guiding and limiting role for the outer sleeve 10, further limiting the swing range of the outer sleeve 10, preventing the outer sleeve 10 from sliding out of the V-shaped limiting groove 30 when the swing amplitude is too large, thereby improving the stability and reliability of the needle supporting process.

[0049] The angle β between the first rod 31 and the second rod 32 of the present embodiment is 120° to 150°. For example, the angle β can be 120°, 130°, 140° or 150°, so that the angle β can be adapted to the natural swing amplitude of the outer sleeve 10. If the angle β is too small (i.e., less than 120°), it is easy to block the second opening of the V-shaped limit groove 30, which is not conducive to the use of the auxiliary needle support. If the angle β is too large (i.e., greater than 150°), for example, when β=170°, the first rod 31 is connected to the adjacent second rod 32 to form a straight rod, which is difficult to guide the outer sleeve 10. After a slight swing, the outer sleeve 10 is difficult to return to the V-shaped bend of the V-shaped limit groove 30.

[0050] Furthermore, the first ends of the two first rods 31 are smoothly connected, and the second ends of the first rods 31 are smoothly connected with the second rods 32 in a one-to-one correspondence. That is, the needle support rod group 3 forms three V-shaped bends, and the three V-shaped bends are rounded, so that the outer sleeve 10 can slide smoothly along the first rod 31 and the second rod 32, avoiding jamming during the swinging process of the outer sleeve 10.

[0051] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention.
