Description

Technical Field

[0001] The invention belongs to the technical field of needle patrol equipment, and in particular is a needle patrol equipment for operating room nursing and a use method thereof. Background Art

[0002] Suture needles are key tools during surgical operations. However, due to the complexity of surgical operations and the particularity of the operating room environment, suture needles are very easy to be lost.

[0003] Usually, for suture needles that fall on the ground, medical staff usually search for them visually or with small metal detection equipment. Since some suture needles are small in size (usually 0.2mm to 1.3mm), they may be affected by the reflective area on the ground to form a visual blind spot, thereby increasing the difficulty of visual search for medical staff. At the same time, for some titanium alloy needles and some austenitic stainless steel suture needles (such as 316 stainless steel), since titanium alloy needles are usually non-magnetic or weakly magnetic and have weak conductivity, it is extremely difficult for medical staff to detect them using small metal detection equipment. For 316 stainless steel needles, they are generally non-magnetic or weakly magnetic at room temperature. Since they have conductive properties, they trigger signals through metal conductivity, but when the needle diameter is less than 1mm, it is also extremely difficult for small metal detection equipment to detect. Therefore, medical staff can only search for such needles visually, which reduces the search efficiency.

[0004] Therefore, in order to solve the above problems, a needle-finding device for operating room nursing and a method of using the same are proposed. Summary of the invention

[0013] Preferably, the cover body is provided with an insertion hole, and the support is also fixedly connected with a pin which can be inserted into the insertion hole.

[0014] Preferably, the driving wheel assembly includes toothed rollers movably mounted on both sides of the support, and a transmission shaft is also movably mounted on the support. Both ends of the transmission shaft extend to the outside of the support and are fixedly connected with gears meshing with the toothed rollers. A synchronous belt is also equidistantly arranged on the transmission shaft, and a plurality of the transmission rollers are connected to the transmission shaft through a synchronous belt.

[0015] Preferably, the toothed roller has the same diameter and rotation speed as the inflatable membrane 1 and the inflatable membrane 2, respectively.

[0016] Preferably, a reciprocating thread is provided in the middle of the second roller shaft;

[0017] The push plate group 1 includes a frame body 1 movably connected to the inside of the support, the middle part of the frame body 1 is threadedly connected to the middle part of one of the roller shafts 2, and a plurality of push plates 1 are movably connected to the inside of the support, and the plurality of push plates 1 are respectively located on one side of the inflatable membrane 1 and the inflatable membrane 2, and a push rod 1 fixedly connected to the push plate 1 is also fixedly connected to the frame body 1.

[0018] Preferably, the push plate group 2 includes a frame body 2 movably connected to the inside of the support, the middle part of the frame body 2 is threadedly connected to the middle part of one of the roller shafts 2, and a plurality of push plates 2 are movably connected to the inside of the support, and the plurality of push plates 2 are respectively located on the other side of the inflatable membrane 1 and the inflatable membrane 2, and a push rod 2 fixedly connected to the push plate 2 is also fixedly connected to the frame body 2.

[0020] A guard plate is fixedly connected to the other side of the support, and the bottom of the guard plate is in contact with the ground.

[0021] A method for using a needle-finding device for operating room nursing, using a needle-finding device for operating room nursing, the method of use is as follows: the medical staff places the device on the ground and pushes the device to move so that the support drives the transmission roller one to rotate through the driving wheel assembly, at this time, several transmission rollers one will respectively drive the shaft body one and the shaft body two to rotate, thereby making the inflatable membrane one and the inflatable membrane two move along the ground, when the needle is located under the inflatable membrane one or the inflatable membrane two, the needle will pierce the inflatable membrane one or the inflatable membrane two, at this time the medical staff can open the cover body and check whether the inflatable membrane one or the inflatable membrane two is broken, thereby determining the position of the needle.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In the above scheme, the medical staff places the device on the ground and pushes the device to move so that the support drives the driving roller 1 to rotate through the driving wheel assembly. At this time, the plurality of driving rollers 1 respectively drive the shaft body 1 and the shaft body 2 to rotate, thereby making the inflatable membrane 1 and the inflatable membrane 2 move along the ground. When the needle is located under the inflatable membrane 1 or the inflatable membrane 2, the needle will pierce the inflatable membrane 1 or the inflatable membrane 2. At this time, the medical staff can open the cover body and check whether the inflatable membrane 1 or the inflatable membrane 2 is broken, so as to determine the position of the needle, thereby solving the problem that needles made of some special materials can only be found by visual means.

[0024] The above scheme drives the driving wheel assembly when the device moves, and the driving roller 1 also drives the roller shaft 2 to rotate through the shaft body 1. The rotation of the two sets of inflatable membranes 1 drives the frame body 1 and the frame body 2 to move back and forth, so that the push plate 1 and the push plate 2 continuously move toward each other and squeeze the inflatable membrane 1 and the inflatable membrane 2. At this time, when the needle contacts the inflatable membrane 1 and the inflatable membrane 2, due to the deformation of the two, it is easier for the needle to rupture when it contacts the inflatable membrane 1 or the inflatable membrane 2, thereby improving the accuracy of needle finding.

[0025] The above scheme causes the transmission shaft to drive the transmission roller 2 to rotate through the synchronous belt 2 when the support moves, so that several flexible arc plates intermittently contact the ground, preventing the flexible arc plates from pushing the needle away as the support moves. At the same time, through the blocking of the flexible arc plates and the guard plates, when the inflatable membrane 1 or the inflatable membrane 2 ruptures, the airflow generated by the rupture of both is prevented from flushing the needle out of the support.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 9As shown, the present invention provides a needle-finding device for operating room nursing, comprising a support 1 and a cover body 2 buckled and mounted thereon, a limiting roller 21 being mounted on the cover body 2, when the cover body 2 is buckled on the support 1, a plurality of groups of limiting rollers 21 are respectively located above the corresponding supporting components 11 and respectively limit the shaft body 1 311 and the shaft body 2 321 in the vertical direction; a plug hole 22 is provided on the cover body 2, and a plug 12 which can be inserted into the plug hole 22 is also fixedly connected to the support 1; further comprising: a needle-finding mechanism 3 which is movably mounted between the support 1 and the cover body 2; a driving wheel assembly 4 which is arranged on the support 1 for supporting the support 1 and driving the needle-finding mechanism 3 to rotate; wherein a plurality of groups of supporting components 11 for supporting the needle-finding mechanism 3 are arranged on the support 1;

[0038] The needle-finding mechanism 3 comprises a needle-finding member 1 31 and a needle-finding member 2 32 which are parallel and staggered to each other. The needle-finding member 1 31 comprises a shaft 1 311 and an inflatable membrane 1 312 sleeved on the outside of the shaft 1 311. The needle-finding member 2 32 comprises a shaft 2 321 and an inflatable membrane 2 322 sleeved on the outside of the shaft 2 321. The bottoms of the inflatable membrane 1 312 and the inflatable membrane 2 322 extend to the bottom of the support 1 and can both contact the ground.

[0039] The support assembly 11 further includes a roller shaft 111, a roller shaft 2 112 and a transmission roller 113, all of which can support the shaft body 1 311 and the shaft body 2 321. The transmission roller 113 is in transmission connection with the driving wheel assembly 4. The roller shaft 2 112 and the transmission roller 1 113 can support the ends of two adjacent shaft bodies 1 311 or shaft bodies 2 321.

[0040] The driving wheel assembly 4 can drive the transmission roller 113 to rotate so that the needle finding member 1 31 and the needle finding member 2 32 rotate in the same direction;

[0041] The support 1 is also provided with a push plate group 1 5 and a push plate group 2 6, which are respectively connected to the two roller shaft groups 2 112 and can move toward each other to squeeze the needle-finding mechanism 3;

[0042] By adopting the above scheme, the medical staff places the device on the ground and pushes the device to move so that the support 1 and the driving wheel assembly 4) drive the transmission roller 113 to rotate. At this time, the plurality of transmission rollers 113 will respectively drive the shaft 1 311 and the shaft 2 321 to rotate, thereby making the inflatable membrane 1 312 and the inflatable membrane 2 322 move along the ground. When the needle is located under the inflatable membrane 1 312 or the inflatable membrane 2 322, the needle will pierce the inflatable membrane 1 312 or the inflatable membrane 2 322. At this time, the medical staff can open the cover body 2 and check whether the inflatable membrane 1 312 or the inflatable membrane 2 322 is broken, so as to determine the position of the needle, thereby solving the problem that needles made of some special materials can only be found by visual inspection.

[0043] like Figure 1-Figure 5 and Fig. 9 As shown, the driving wheel assembly 4 includes toothed rollers 41 movably mounted on both sides of the support 1, and a transmission shaft 42 is also movably mounted on the support 1. Both ends of the transmission shaft 42 extend to the outside of the support 1 and are fixedly connected with gears 43 meshing with the toothed rollers 41. A synchronous belt 1 44 is also equidistantly arranged on the transmission shaft 42, and a plurality of transmission rollers 113 are all connected to the transmission shaft 42 through the synchronous belt 1 44. The toothed rollers 41 have the same diameter and rotation speed as the inflatable membrane 1 312 and the inflatable membrane 2 322 respectively.

[0044] By adopting the above scheme, the toothed roller 41 can roll along the ground by moving the support 1, thereby driving the transmission roller 113 to rotate in the opposite direction through the gear 43, the transmission shaft 42 and the synchronous belt 1 44. When the shaft 1 311 or the shaft 2 321 contacts the transmission shaft 113, the shaft 2 321 and the shaft 1 311 will be transformed into the same rolling direction as the toothed roller 41.

[0045] like Figure 3 , Figure 5 and Figure 6-Figure 8 As shown, a reciprocating thread is provided in the middle of the roller shaft 112;

[0046] The push plate group 1 5 includes a frame 1 51 movably connected to the inside of the support 1, the middle part of the frame 1 51 is threadedly connected to the middle part of one of the roller shafts 2 112, and a plurality of push plates 1 53 are movably connected to the inside of the support 1, and the plurality of push plates 1 53 are respectively located on one side of the inflatable membrane 1 312 and the inflatable membrane 2 322, and a push rod 1 52 fixedly connected to the push plate 1 53 is also fixedly connected to the frame 1 51;

[0047] The push plate group 2 6 includes a frame body 2 61 movably connected to the inside of the support 1, the middle part of the frame body 2 61 is threadedly connected to the middle part of one of the roller shafts 2 112, and a plurality of push plates 2 63 are also movably connected to the inside of the support 1, and the plurality of push plates 2 63 are respectively located on the other side of the inflatable membrane 1 312 and the inflatable membrane 2 322, and a push rod 2 62 fixedly connected to the push plate 2 63 is also fixedly connected to the frame body 2 61;

[0048] By adopting the above scheme, through the transmission of the driving wheel assembly 4 when the device moves, the transmission roller 113 will also drive the roller shaft 2 112 to rotate through the shaft body 1 311, and the rotation of the two sets of inflatable membranes 1 312 will drive the frame body 1 51 and the frame body 2 61 to move back and forth, so that the push plate 1 53 and the push plate 2 63 continue to move toward each other and realize the squeezing of the inflatable membrane 1 312 and the inflatable membrane 2 322. At this time, when the needle contacts the inflatable membrane 1 312 and the inflatable membrane 2 322, due to the deformation of the two, it is easier for the needle to rupture when it contacts the inflatable membrane 1 312 or the inflatable membrane 2 322, thereby avoiding the situation where the inflatable membrane 1 312 or the inflatable membrane 2 322 presses over the needle and cannot rupture, thereby improving the accuracy of needle finding.

[0049] like Figure 1-Figure 5 and Fig. 9 As shown, a transmission roller 2 7 is movably mounted on one side of the support 1, and a flexible arc plate 71 which can contact the ground in sequence is arranged in an annular array on the outer periphery of the transmission roller 2 7, and a synchronous belt 2 72 is arranged on the flexible arc plate 71, and the flexible arc plate 71 is connected to the transmission shaft 42 through the synchronous belt 2 72;

[0050] A guard plate 13 is fixedly connected to the other side of the support 1, and the bottom of the guard plate 13 is in contact with the ground;

[0051] By adopting the above scheme, when the support 1 moves, the transmission shaft 42 will also drive the transmission roller 2 7 to rotate through the synchronous belt 2 72, so that a plurality of flexible arc plates 71 are intermittently in contact with the ground, preventing the flexible arc plates 71 from pushing the needle away as the support 1 moves. At the same time, through the blocking of the flexible arc plates 71 and the protective plate 13, when the inflatable membrane 1 312 or the inflatable membrane 2 322 ruptures, the airflow generated by the rupture of the two can prevent the needle from being flushed out of the support 1.

[0052] The working principle and use process of the present invention:

[0053] First, the medical staff places the device on the ground and pushes the device to move, so that the support 1 drives the transmission roller 113 to rotate. At this time, the plurality of transmission rollers 113 will respectively drive the shaft 1 311 and the shaft 2 321 to rotate, thereby making the inflatable membrane 1 312 and the inflatable membrane 2 322 move along the ground. When the needle is located under the inflatable membrane 1 312 or the inflatable membrane 2 322, the needle will pierce the inflatable membrane 1 312 or the inflatable membrane 2 322. At this time, the medical staff can open the cover 2 and check whether the inflatable membrane 1 312 or the inflatable membrane 2 322 is broken, so as to determine the position of the needle.

[0054] When the device moves, since the roller shaft 112 supports the shaft body 1 311, the transmission roller 113 will also drive the roller shaft 112 to rotate through the shaft body 1 311, and the rotation of the two sets of inflatable membranes 1 312 will drive the frame body 1 51 and the frame body 2 61 to move back and forth, so that the push plate 1 53 and the push plate 2 63 continue to move towards each other and squeeze the inflatable membrane 1 312 and the inflatable membrane 2 322. At this time, when the needle contacts the inflatable membrane 1 312 and the inflatable membrane 2 322, due to the deformation of the two, it is easier for the needle to rupture when it contacts the inflatable membrane 1 312 or the inflatable membrane 2 322.

[0055] When the support 1 moves, the transmission shaft 42 will also drive the transmission roller 2 7 to rotate through the synchronous belt 2 72, so that several flexible arc plates 71 intermittently contact the ground, preventing the flexible arc plates 71 from pushing the needle away as the support 1 moves. At the same time, through the blocking of the flexible arc plates 71 and the protective plate 13, when the inflatable membrane 1 312 or the inflatable membrane 2 322 ruptures, the airflow generated by the rupture of the two can prevent the needle from being flushed out of the support 1.
