[0033] In the related art, after the puncture needle is inserted, in order to prevent the puncture needle from moving, the medical staff needs to hold a fixing tool to fix the puncture needle, which makes it inconvenient for the medical staff to drain the accumulated fluid through the puncture needle, and further makes the thoracic and abdominal puncture process inconvenient.

[0034] In order to at least solve the problem in the related art that the puncture needle needs to be manually fixed after insertion, the embodiment of the present application proposes a thoracoabdominal puncture fixation device 100, which can fix the puncture needle, thereby facilitating the thoracoabdominal puncture process.

[0035] The following describes the chest and abdomen puncture and fixation device 100 according to an embodiment of the present application with reference to the accompanying drawings.

[0036] Combine Figure 1 and Figure 2 As shown, the thoracic and abdominal puncture fixation device 100 of the embodiment of the present application includes a fixing pad 1, a plurality of clamping members 2 and an adjusting member 3. The fixing pad 1 is suitable for contacting with the chest and abdomen, and the fixing pad 1 is provided with a puncture hole 11 passing through the fixing pad 1, and the puncture hole 11 is suitable for being passed through by a puncture needle. The plurality of clamping members 2 can be movably arranged on the fixing pad 1, and the plurality of clamping members 2 act in groups. The grouped clamping members 2 are configured to be able to approach each other to clamp the puncture needle, and the grouped clamping members 2 are also configured to be able to move away from each other to release the puncture needle. The adjusting member 3 is provided on the fixing pad 1, and the adjusting member 3 is transmission-connected to the plurality of clamping members 2 so as to be able to drive the grouped clamping members 2 to approach or move away from each other.

[0037] The group of clamping members 2 includes at least two clamping members 2 , for example, the group of clamping members 2 includes two clamping members 2 , and for another example, the group of clamping members 2 includes three clamping members 2 .

[0038] The puncture needle can be clamped by the group of clamping members 2 approaching each other, and the puncture needle can be released by the group of clamping members 2 moving away from each other.

[0039] During thoracoabdominal puncture, the fixation pad 1 is secured to the chest and abdomen, bringing the chest and abdomen into contact with the fixation pad 1, and the needle is inserted through the puncture hole 11. After the puncture needle is inserted, the adjustment member 3 drives the group of clamping members 2 toward each other to clamp the puncture needle, thereby securing the puncture needle. To withdraw the puncture needle, the adjustment member 3 drives the group of clamping members 2 away from each other to release the clamping force, allowing the puncture needle to be withdrawn.

[0040] In the thoracic and abdominal puncture fixation device 100 of the embodiment of the present application, after the puncture needle is inserted, the adjusting member 3 drives the grouped clamping members 2 to approach each other to clamp the puncture needle, thereby achieving fixation of the puncture needle. Therefore, the thoracic and abdominal puncture fixation device 100 of the embodiment of the present application can avoid manual fixation of the puncture needle, thereby making the thoracic and abdominal puncture process convenient to operate.

[0041] Optionally, the adjusting member 3 includes a cylinder, the telescopic end of the cylinder is connected to the clamping member, and the telescopic movement of the telescopic end drives the clamping members 2 to move closer to or away from each other.

[0042] Combine Figure 1 、 Figure 2 and Figure 4As shown, in some embodiments, the adjusting member 3 includes a threaded rod 31 rotatably provided on the fixing pad 1, and in the extension direction of the threaded rod 31, the threaded rod 31 has a left-handed threaded portion 311 and a right-handed threaded portion 312 that are relatively arranged and have opposite thread rotation directions. The clamping member 2 includes a threaded member 21 and a clamping member 22 that are connected to each other. The group of clamping members 2 includes two clamping members 2, the threaded member 21 of one clamping member 2 is threadedly connected to the left-handed threaded portion 311, and the threaded member 21 of the other clamping member 2 is threadedly connected to the right-handed threaded portion 312. In the extension direction of the threaded rod 31, the clamping member 22 is movably connected to the fixing pad 1 to limit the synchronous movement of the threaded member 21 relative to the threaded rod 31, and the clamping member 22 is suitable for clamping the puncture needle.

[0043] The left-handed threaded portion 311 and the right-handed threaded portion 312 have opposite thread rotation directions. For example, the left-handed threaded portion 311 has a left-hand thread rotation direction, while the right-handed threaded portion 312 has a right-hand thread rotation direction. In some examples, the threaded rod 31 is a counter-threaded screw. Thus, when the threaded rod 31 is rotated, the two clamping members 2 in the group move in opposite directions. In other words, the two clamping members 2 in the group can move relative to each other or away from each other under the drive of the threaded rod 31, thereby moving closer to or farther away from each other.

[0044] The clamping member 22 is connected to the fixing pad 1 to limit the synchronous movement of the threaded member 21 relative to the threaded rod 31. Therefore, when the threaded rod 31 is rotated, the threaded member 21 can rotate relative to the threaded rod 31, thereby allowing the threaded member 21 to move along the threaded rod 31, and then the threaded member 21 can drive the clamping member 2 to move. In addition, because the clamping member 22 is movably connected to the fixing pad 1, the fixing pad 1 can avoid hindering the movement of the clamping member 22.

[0045] After the needle is inserted, the threaded rod 31 is rotated to drive the two clamping members 2 in the group to approach each other, so that the puncture needle can be clamped and fixed. When the puncture needle needs to be withdrawn, the threaded rod 31 is used to drive the two clamping members 2 in the group to move away from each other to release the clamping of the puncture needle, so that the puncture needle can be withdrawn.

[0046] The two clamping members 2 in a group are driven by the threaded rod 31 , so that the thoracic and abdominal puncture and fixation device 100 of this embodiment has a simple and compact structure and low cost.

[0047] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown, in some embodiments, the fixing pad 1 is provided with a slide groove 12, the extension direction of the slide groove 12 is consistent with the extension direction of the threaded rod 31, the clamping member 22 includes a sliding portion 221 and a clamping portion 222 connected to each other, the clamping portion 222 is suitable for clamping the puncture needle, one end of the sliding portion 221 in the thickness direction of the fixing pad 1 is connected to the clamping portion 222, and the other end of the sliding portion 221 in the thickness direction of the fixing pad 1 can be slidably provided in the slide groove 12.

[0048] The other end of the sliding portion 221 in the thickness direction of the fixing pad 1 is slidably disposed in the sliding groove 12 to limit the synchronous movement of the threaded member 21 relative to the threaded rod 31 .

[0049] In addition, the sliding portion 221 and the sliding groove 12 can also guide the movement of the clamping portion 222, making the movement of the clamping portion 222 more precise.

[0050] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, in some embodiments, the clamping portion 222 includes a clamping section 2221 and a connecting section 2222, one end of the connecting section 2222 in the length direction of the clamping member 22 is connected to the threaded member 21, the other end of the connecting section 2222 in the length direction of the clamping member 22 is connected to the clamping section 2221, and one end of the sliding portion 221 in the thickness direction of the fixed pad 1 is connected to the connecting section 2222. In the two clamping members 2 in the group, the clamping sections 2221 of the two clamping members 2 are located between the connecting sections 2222 of the two clamping members 2.

[0051] By positioning the clamping segments 2221 of the two clamping members 2 between the connecting segments 2222 of the two clamping members 2 , the clamping segments 2221 can more easily clamp the puncture needle.

[0052] Optionally, the surface of the clamping section 2221 is provided with anti-slip grooves, thereby increasing the roughness of the surface of the clamping section 2221, thereby increasing the friction between the clamping section 2221 and the puncture needle, and further increasing the degree of stability of the clamping section 2221 in clamping the puncture needle.

[0053] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the fixing pad 1 is provided with a first fixing seat 13 and a second fixing seat 14 , the left-handed thread portion 311 is rotatably provided in the first fixing seat 13 , and the right-handed thread portion 312 is rotatably provided in the second fixing seat 14 .

[0054] The threaded rod 31 can be installed through the first fixing seat 13 and the second fixing seat 14 , so that the threaded rod 31 can be firmly arranged on the fixing pad 1 .

[0055] like Figure 2 As shown, in some embodiments, the adjusting member 3 further includes a first adjusting member 32 and a second adjusting member 33. The first adjusting member 32 is threadedly connected to the left-handed threaded portion 311 and can rotate synchronously with the threaded rod 31.

The second adjusting member 33 is threadedly connected to the right-handed threaded portion 312 and can rotate synchronously with the threaded rod 31. The second adjusting member 33 is located on a side of the second fixing seat 14 away from the first fixing seat 13 and abuts against the second fixing seat 14.

[0056] The threaded rod 31 can be installed by the first adjusting member 32 and the second adjusting member 33 to prevent the threaded rod 31 from moving along the extending direction of the threaded rod 31 .

[0057] like Figure 2 As shown, in some embodiments, the first adjusting member 32 includes a first threaded portion 321 and a first adjusting portion 322 that are interconnected. The first threaded portion 321 is threadedly connected to the left-handed threaded portion 311 and abuts against the first fixing seat 13. The first adjusting portion 322 is located on the side of the first threaded portion 321 facing away from the first fixing seat 13, and the radial dimension of the first adjusting portion 322 is greater than the radial dimension of the first threaded portion 321. The second adjusting member 33 includes a second threaded portion 331 and a second adjusting portion 332 that are interconnected. The second threaded portion 331 is threadedly connected to the right-handed threaded portion 312 and abuts against the second fixing seat 14. The second adjusting portion 332 is located on the side of the second threaded portion 331 facing away from the second fixing seat 14, and the radial dimension of the second adjusting portion 332 is greater than the radial dimension of the second threaded portion 331.

[0058] The first adjusting portion 322 and the second adjusting portion 332 can facilitate screwing of the threaded rod 31 , thereby reducing the difficulty of rotating the threaded rod 31 .

[0059] Combine Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the fixing pad 1 is further provided with a third fixing seat 15 , which is located between the first fixing seat 13 and the second fixing seat 14 , and the threaded rod 31 is rotatably provided through the third fixing seat 15 .

[0060] The threaded rod 31 can be further mounted via the third fixing seat 15 , thereby further enabling the threaded rod 31 to be firmly positioned on the fixing pad 1 .

[0061] Combine Figure 1 、 Figure 2 and Figure 3As shown, in some embodiments, the fixing pad 1 includes multiple first pad bodies 16 and multiple flexible connecting pads 17. The multiple first pad bodies 16 are arranged at intervals. The first pad bodies 16 are suitable for bonding to the chest and abdomen. Two adjacent first pad bodies 16 are flexibly connected by the flexible connecting pad 17.

[0062] It can be understood that the first pad body 16 is a hard structure so as to increase the bearing capacity of the fixing pad 1 .

[0063] The fixing pad 1 includes multiple first pad bodies 16, and two adjacent first pad bodies 16 are flexibly connected by a flexible connecting pad 17, which can enable any first pad body 16 to be displaced relative to other first pad bodies 16 in the thickness direction of the fixing pad 1, so that the fixing pad 1 can better fit and adhere to the uneven chest and abdominal skin, thereby increasing the fixing effect of the fixing pad 1.

[0064] Combine Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the fixing pad 1 also includes a second pad body 18 suitable for bonding to the chest and abdomen, the clamping member 2, the adjustment member 3 and the puncture hole 11 are all arranged on the second pad body 18, and multiple first pad bodies 16 are arranged in sequence in the circumferential direction of the second pad body 18, and the first pad body 16 and the second pad body 18 are flexibly connected by a flexible connecting pad 17.

[0066] The second pad 18 can support the clamping member 2 and the adjusting member 3, making the clamping member 2 and the adjusting member 3 more stable. In addition, the clamping member 2, the adjusting member 3 and the puncture hole 11 are all provided on the second pad 18, which can make the position distribution of the clamping member 2, the adjusting member 3 and the puncture hole 11 reasonable.

[0067] The first pad body 16 and the second pad body 18 are flexibly connected by the flexible connecting pad 17, which can enable the second pad body 18 to be displaced relative to the other first pad bodies 16 in the thickness direction of the fixing pad 1, and can also enable any first pad body 16 to be displaced relative to the second pad body 18 and the other first pad bodies 16 in the thickness direction of the fixing pad 1, thereby increasing the stability of the clamping member 2 and the adjusting member 3, and enabling the fixing pad 1 to better fit and adhere to the uneven chest and abdominal skin.
