[0035] During the process of thoracic and abdominal puncture, the puncture needle needs to maintain the correct angle relative to the chest and abdomen. When the angle of the puncture needle is deviated, the puncture needle is likely to damage blood vessels or nerves.
[0036] However, the related technology lacks a device to assist in needle insertion, which means that medical staff can only insert the puncture needle based on experience. The insertion angle of the puncture needle is easily offset, which can easily damage the patient's nerves or blood vessels.
[0037] In order to at least solve the problem of the puncture needle's insertion angle being easily deviated, the embodiment of the present application proposes a thoracoabdominal puncture assisting device 100 that can guide the insertion movement of the puncture needle, thereby reducing the probability of the puncture needle's insertion angle being deviated.
[0038] The following describes the thoracoabdominal puncture assist device 100 according to an embodiment of the present application with reference to the accompanying drawings.
[0039] Combine Figure 1 and Figure 2As shown, the thoracoabdominal puncture assist device 100 of the embodiment of the present application includes: a housing 1, a loading member 2, and a fastener 3. In the longitudinal direction a of the housing, one end of the housing 1 is configured as an abutment portion 11, which is suitable for abutting against the chest and abdomen. The abutment portion 11 is provided with a puncture hole 111 suitable for being passed through by a puncture needle. The housing 1 defines a receiving cavity 12 extending along the longitudinal direction a of the housing, and the receiving cavity 12 is connected to the puncture hole 111. The loading member 2 is movably disposed in the receiving cavity 12 along the longitudinal direction a of the housing. The loading member 2 is provided with a loading hole 211 suitable for loading the puncture needle. In the longitudinal direction a of the housing, the loading hole 211 is arranged opposite to the puncture hole 111. The fastener 3 is movably disposed on the loading member 2. The fastener 3 is configured to approach the loading hole 211 to abut against and secure the puncture needle, and is also configured to move away from the loading hole 211 to separate from the puncture needle.
[0040] Before inserting the puncture needle, the puncture needle is loaded into the loading hole 211. The position of the fastener 3 is adjusted so that the fastener 3 is close to the loading hole 211, so that the fastener 3 abuts the puncture needle and fixes the puncture needle to the loading member 2. The abutting portion 11 abuts the chest and abdomen so that the longitudinal direction a of the housing is consistent with the insertion angle of the puncture needle.
[0041] When the puncture needle is inserted, the loading part 2 is driven to approach the abutment part 11 along the length direction a of the shell. Since the loading hole 211 and the puncture hole 111 are arranged opposite to each other in the length direction a of the shell, and the accommodating cavity 12 is connected to the puncture hole 111, the puncture needle can extend out of the accommodating cavity 12 through the puncture hole 111 and pierce into the chest and abdomen.
[0042] After the puncture needle is inserted, the position of the fastener 3 is adjusted so that the fastener 3 is away from the loading hole 211, so that the fastener 3 is separated from the puncture needle, so that the fastener 3 contacts the fixation of the puncture needle, and then the thoracic and abdominal puncture auxiliary device 100 of the embodiment of the present application can be separated from the puncture needle, so as to avoid the thoracic and abdominal puncture auxiliary device 100 of the embodiment of the present application hindering the operation of medical staff in subsequent operation steps.
[0043] The thoracoabdominal puncture assist device 100 of the embodiment of the present application can secure the puncture needle to the carrier 2 via the fastener 3, and can abut against the chest and abdomen via the abutment portion 11, thereby aligning the length direction a of the housing with the insertion angle of the puncture needle. The carrier 2 is driven along the length direction a of the housing toward the abutment portion 11, and the puncture needle can extend through the puncture hole 111, extend out of the accommodating cavity 12, and penetrate into the chest and abdomen. The thoracoabdominal puncture assist device 100 of the embodiment of the present application can guide the insertion movement of the puncture needle, thereby making the insertion movement of the puncture needle more accurate and reducing the probability of the puncture needle's insertion angle being offset.
[0044] Optionally, the abutting portion 11 has an abutting surface suitable for abutting against the chest and abdomen, the abutting surface intersecting the longitudinal direction a of the shell. In other words, the abutting surface can be perpendicular to the longitudinal direction a of the shell, or can form an angle other than 90° with the longitudinal direction a of the shell.
[0045] By virtue of the abutting surface intersecting with the length direction a of the shell, the abutting surface can adapt to various needle insertion angles.
[0046] Combine Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, in some embodiments, the loading member 2 includes a loading portion 21, a loading hole 211 is provided in the loading portion 21, and the loading portion 21 defines a passage hole 212, and the loading hole 211 extends along the length direction a of the shell.
[0047] In the length direction of the fastener 3, the loading hole 211 forms a first opening 2111 near one end of the fastener 3 and is connected to the channel hole 212. The fastener 3 is movably arranged in the loading part 21, and a part of the fastener 3 is located in the channel hole 212 and is arranged opposite to the first opening 2111.
[0048] A portion of the fastener 3 is located within the passage hole 212. When the fastener 3 is close to the passage hole 212, the fastener 3 and the inner wall of the passage hole 212 can squeeze the puncture needle, thereby securing the puncture needle. When the fastener 3 is away from the passage hole 212, the fastener 3 can separate from the puncture needle, thereby releasing the squeezing effect on the puncture needle.
[0049] The loading portion 21 of the embodiment of the present application has a reasonable structural distribution and a simple and compact structure.
[0050] Combine Figure 4 and Figure 5 As shown, in some embodiments, the loading portion 21 has a first wall 213 and a second wall 214 arranged at an angle, the first wall 213 and the second wall 214 define a loading hole 211, and in the length direction of the fastener 3, a first opening 2111 is formed between the first wall 213 and the second wall 214 near the end of the fastener 3, and in the length direction of the fastener 3, the first wall 213 and the second wall 214 are connected to each other away from the end of the fastener 3.
[0051] By setting the first wall 213 and the second wall 214 at an angle, a first opening 2111 is formed between the ends of the first wall 213 and the second wall 214 close to the fastener 3 in the length direction of the fastener 3. The first wall 213 and the second wall 214 are connected to each other at the ends facing away from the fastener 3, which can increase the fixing effect of the loading hole 211 on the puncture needle, so that the puncture needle can be loaded more stably by the loading hole 211.
[0052] Combine Figure 2 、 Figure 4 and Figure 5 As shown, in some embodiments, the fastener 3 is a fastening bolt 31 , the loading portion 21 is provided with a threaded hole communicating with the channel hole 212 , and the fastening bolt 31 is threadedly connected in the threaded hole.
[0053] By providing the fastening bolt 31 , the structures of the fastener 3 and the loading portion 21 can be simplified, and the cost of the thoracoabdominal puncture assisting device 100 according to the embodiment of the present application can be reduced.
[0054] In other embodiments, the fastener 3 is a cylinder, the loading portion 21 is provided with a through hole connected to the channel hole 212 , the telescopic shaft of the cylinder passes through the through hole, and a portion of the telescopic shaft is located in the channel hole 212 .
[0055] The puncture needle can be automatically fixed by arranging the cylinder, thereby reducing the difficulty of fixing the puncture needle.
[0056] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the fastening bolt 31 has a screwing portion 311 suitable for screwing, and the shell 1 is formed with a second opening 13 connected to the accommodating cavity 12, and the second opening 13 and the screwing portion 311 are both located on the same side of the loading portion 21 so that the second opening 13 can expose the screwing portion 311.
[0057] The screwing portion 311 can be exposed through the second opening 13 , so that the screwing portion 311 can avoid being blocked by the housing 1 , thereby facilitating adjustment of the screwing portion 311 .
[0058] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the loading member 2 further includes a first guide portion 22 connected to the loading portion 21 . The first guide portion 22 is located in the accommodating cavity 12 , and the first guide portion 22 is slidably in contact with the inner wall of the accommodating cavity 12 .
[0059] The first guide portion 22 is slidably in contact with the inner wall of the accommodating cavity 12 to guide the loading member 2 , thereby enabling the loading member 2 to move more accurately in the longitudinal direction a of the housing.
[0060] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, in some embodiments, the shell 1 defines a propulsion slide 14 extending along the length direction a of the shell, and the thoracoabdominal puncture auxiliary device 100 also includes a propulsion member 4, which includes a propulsion portion 41 and a sliding portion 42 connected to each other. The sliding portion 42 is slidably arranged on the propulsion slide 14 and is connected to the first guide portion 22. The propulsion portion 41 is located on the side of the sliding portion 42 away from the first guide portion 22 and is located outside the shell 1.
[0061] The propulsion portion 41 outside the housing 1 can drive the loading member 2 to move, thereby reducing the difficulty of driving the loading member 2 to move.
[0062] In addition, the sliding portion 42 can be guided by the propulsion slide 14 , so that the movement of the propulsion portion 41 is more precise, and further when the propulsion portion 41 drives the loading member 2 to move, the movement of the loading member 2 is more precise.
[0063] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, two first guide portions 22, two propulsion slides 14, and two propulsion members 4 are each provided. The two first guide portions 22, two propulsion slides 14, and two propulsion members 4 are all arranged opposite each other in the first direction, and the length direction a of the housing is perpendicular to the first direction. In other words, the two first guide portions 22 are arranged opposite each other in the first direction, the two propulsion slides 14 are arranged opposite each other in the first direction, and the two propulsion members 4 are arranged opposite each other in the first direction.
[0064] As some examples, the first direction is a width direction c of the housing.
[0065] As some other examples, the first direction is the height direction b of the shell.
[0066] The two first guide parts 22, the two propulsion slides 14 and the two propulsion members 4 are all arranged relative to each other in the first direction, so that the loading member 2 can be driven to move by the two propulsion members 41 arranged relative to each other in the first direction, thereby increasing the stability of the movement of the loading member 2.
[0067] Combine Figure 1 、 Figure 2 and Figure 4 As shown, in some embodiments, the loading part 2 also includes a second guide portion 23, which is connected to the loading part 21 in the second direction. Along the extension direction of the shell 1, the shell 1 defines a slide groove, and the second guide portion 23 is slidably arranged in the slide groove.

[0069] As some other examples, the first direction is the height direction b of the shell, and the second direction is the width direction c of the shell.
[0070] The second guide portion 23 can be guided by the sliding groove, thereby further making the movement of the loading component 2 more precise.
[0071] like Figure 4 As shown, in some embodiments, the second guide portion 23 is provided with a process hole 231 .
[0072] The wall thickness of the second guide portion 23 can be reduced by providing the process hole 231 , thereby preventing the second guide portion 23 from shrinking, thereby facilitating the manufacturing of the second guide portion 23 .
