Description

Technical Field

[0001] The present invention relates to the technical field of needle finders, and particularly to a structure of a needle finder for the operating room floor. Background Art

[0002] Surgical suture needles, also known as medical suture needles, are indispensable instruments in surgical operations. They are mainly used to guide the suture thread through tissues to achieve tissue suturing. In essence, they are suture needles. According to different shapes, uses, and manufacturing processes, surgical suture needles can be divided into various types, such as round needles, corner needles, spatula needles, straight needles, etc. Among them, round needles are mostly used for suturing deep tissues, while corner needles, due to their sharp characteristics, are often used for suturing tough tissues such as skin, cartilage, and ligaments.

[0003] Due to the fineness of surgical suturing, suture needles are often designed to be quite small. After the operation is completed, before the doctor closes the wound, all medical devices used during the operation, especially the number of suture needles, must be carefully checked. Once a suture needle is found missing, the operation must be immediately stopped, and the surgical staff needs to carefully search for the lost suture needle on the operating table and the floor. Searching for the lost suture needle mainly relies on medical staff using a needle finder for manual search, and some needle finders use magnets to adsorb suture needles to achieve the purpose of finding suture needles, such as the invention patents with publication numbers CN107049515B and CN109998701B.

[0004] However, we found in actual use that when medical staff are handing over suture needles, the suture needles may fall due to non-standard clamping actions or improper transmission. If the suture needle falls to the ground, the high-brightness operating room shadowless lamp can provide sufficient light for medical staff to observe and find it. However, there are many gaps on the operating table. If the suture needle falls into the gaps inside the operating table or in a narrow space, it is impossible to quickly find the position of the small suture needle with the naked eye, which affects the surgical process. Therefore, we propose a structure of a needle finder for the operating room floor. Summary of the Invention

[0005] One technical problem to be solved by this application is: after the suture needle falls into a narrow gap, how to search for the suture needle in the gap so as to timely take out the suture needle and enable the operation to proceed normally.

If the suture needle is adsorbed by the needle-finding magnetic ring, the suture needle can be directly taken out by holding the handle. If the suture needle gets stuck in the gap, the needle-finding magnetic ring will directly adsorb on the suture needle when approaching it. If the medical staff continues to control the handle to move, the needle-finding magnetic ring will automatically disengage between the baffle and the connecting tube, and pull out the guiding rope through the auxiliary plate and the auxiliary rod. When the medical staff finds that the guiding rope is pulled out, they can find the suture needle stuck in the gap along the guiding rope. It can not only quickly help the medical staff find the suture needle, but also explore the suture needle at the position that the medical staff cannot observe in the gap.

Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1: Please refer to Figure 1-11 , the present invention provides a technical solution: a structure of a needle-seeking device for the operating room floor, including a needle-seeking magnetic ring 1, and further including

[0037] a holding handle 2, arranged on one side of the needle-seeking magnetic ring 1, and controlling the movement of the needle-seeking magnetic ring 1 by using the holding handle 2;

[0038] a gap-exploring component 3, arranged on one side of the holding handle 2, and driving the needle-seeking magnetic ring 1 to move by using the gap-exploring component 3 to find the suture needle dropped in the gap;

[0039] an adsorption component 4, arranged in the holding handle 2, and adsorbing the suture needle dropped on the surface of the operating table by using the adsorption component 4.

[0040] Please refer to Figure 1-8, the gap exploration component 3 includes a connecting member 5 provided at one end of the holding handle 2. The holding handle 2 is connected to the needle-seeking magnetic ring 1 by using the connecting member 5. A guiding member 6 is provided inside the holding handle 2 to guide medical staff to find the position of the needle-seeking magnetic ring 1 after adsorbing the suture needle. An extrusion member 7 is provided outside the holding handle 2 to limit the distance between the needle-seeking magnetic ring 1 and the holding handle 2.

[0041] Please refer to Figure 2-4 , the connecting member 5 includes a connecting pipe 51 provided at one end of the holding handle 2. Two connecting plates 52 are provided at the end of the connecting pipe 51 away from the holding handle 2. A baffle 53 is provided at the end of the two connecting plates 52 away from the connecting pipe 51. The needle-seeking magnetic ring 1 is slidably arranged between the baffle 53 and the connecting pipe 51. Medical staff hold the holding handle 2 and insert the end of the connecting pipe 51 close to the needle-seeking magnetic ring 1 into the gap of the operating table, and keep the connecting pipe 51 in an upright state. The two connecting plates 52 provided at one end of the connecting pipe 51 will cooperate with the baffle 53 to prevent the needle-seeking magnetic ring 1 from directly adsorbing on the iron frame at the bottom of the operating table. The function is that the thin connecting pipe 51 is more convenient for the needle-seeking magnetic ring 1 to be inserted into the gap of the operating table, and the baffle 53 can support the bottom of the needle-seeking magnetic ring 1 when the needle-seeking magnetic ring 1 approaches the iron frame of the operating table, preventing the needle-seeking magnetic ring 1 from adsorbing on the iron frame and thus affecting the efficiency of finding the suture needle.

[0042] Please refer to Figure 3-7 , the guiding member 6 includes a guiding shaft 61 rotatably arranged inside the holding handle 2. A winding wheel 62 is provided outside the guiding shaft 61. A guiding rope 63 is provided outside the winding wheel 62. One end of the guiding rope 63 is wound outside the winding wheel 62. An auxiliary rod 64 is provided at the end of the guiding rope 63 away from the winding wheel 62. The guiding rope 63 passes through and is slidably arranged inside the connecting pipe 51 and the needle-seeking magnetic ring 1. An auxiliary plate 65 is provided at the end of the auxiliary rod 64 away from the guiding rope 63. The auxiliary plate 65 is slidably arranged between the needle-seeking magnetic ring 1 and the baffle 53;

[0043] A guiding torsion spring 66 is arranged outside the guiding shaft 61. One end of the guiding torsion spring 66 away from the guiding shaft 61 is arranged inside the holding handle 2. A guiding ratchet wheel 67 is arranged outside the guiding shaft 61. A rotating shaft 68 is rotatably arranged inside the holding handle 2. A guiding ratchet tooth 69 which is matched with the guiding ratchet wheel 67 is arranged outside the rotating shaft 68. A rotating torsion spring 610 is arranged outside the rotating shaft 68. One end of the rotating torsion spring 610 away from the rotating shaft 68 is arranged inside the holding handle 2. When the needle-seeking magnetic ring 1 adsorbs the suture needle and the suture needle is stuck in the gap of the operating table and cannot directly move with the needle-seeking magnetic ring 1, under the movement of the holding handle 2, the needle-seeking magnetic ring 1 will separate from between the baffle 53 and the connecting pipe 51 and drive the auxiliary plate 65 on one side of it to stay at the position where the suture needle is stuck together with it. When the auxiliary plate 65 separates from the baffle 53, the auxiliary rod 64 arranged on one side of the auxiliary plate 65 will stay at the position where the suture needle is stuck together with the auxiliary plate 65, so that the guiding rope 63 at one end of the auxiliary rod 64 is pulled. When the end of the guiding rope 63 close to the auxiliary rod 64 stays at the position of the suture needle and is pulled, the winding wheel 62 will start to rotate under the action of the guiding rope 63, so that the guiding rope 63 is pulled out as the holding handle 2 moves. When the winding wheel 62 rotates, the guiding shaft 61 arranged at its axis will rotate together with the winding wheel 62, so that the guiding ratchet wheel 67 arranged outside the guiding shaft 61 rotates together with the guiding shaft 61. When the guiding rope 63 is pulled out, if the winding wheel 62 is close to the suture needle, the guiding torsion spring 66 arranged outside the guiding shaft 61 will control the rotation of the winding wheel 62 and wind the guiding rope 63 through the winding wheel 62. The rotating shaft 68 arranged inside the holding handle 2 can cooperate with the rotating torsion spring 610 arranged outside it to control the guiding ratchet tooth 69 not to contact the guiding ratchet wheel 67 without external force, so as to avoid affecting the winding of the guiding rope 63 by the winding wheel 62. Its function is that after the needle-seeking magnetic ring 1 adsorbs at the position of the stuck suture needle, medical staff can find the position of the suture needle through the guiding rope 63.

[0044] Please refer to Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 、 Figure 8, the extrusion member 7 includes a fixed block 71 disposed at the top of the holding handle 2. A push rod 72 is slidably disposed within the fixed block 71, and the push rod 72 is slidably disposed within the holding handle 2 and is located above the end of the guiding ratchet 69 away from the rotating shaft 68. A limiting plate 73 is slidably disposed within the fixed block 71, and the push rod 72 is disposed at the center of the limiting plate 73. The push rod 72 is slidably disposed within the fixed plate by means of the limiting plate 73. A compression spring 74 is disposed at the bottom of the limiting plate 73, and the end of the compression spring 74 away from the limiting plate 73 is disposed on the holding handle 2. A pressing handle 75 is disposed at the top of the push rod 72. By pressing the pressing handle 75, the pressing handle 75 moves downward. When the pressing handle 75 moves downward, the push rod 72 disposed at the bottom of the pressing handle 75 will slide within the holding handle 2 and the fixed block 71, and the limiting plate 73 disposed on the outer side of the push rod 72 will move together with the push rod 72. When the push rod 72 moves downward, the push rod 72 will press the end of the guiding ratchet 69 away from the rotating shaft 68, causing the guiding ratchet 69 to be stuck on the guiding ratchet wheel 67, so that the guiding rope 63 can no longer be pulled out from the winding wheel 62. Its function is that by making the guiding rope 63 exposed in the field of vision of medical staff, it is more convenient and faster for medical staff to find the suture needle stuck in the gap.

[0045] Please refer to Figure 1-3 , Figure 5 , Figure 7 , Figure 9-11 , the adsorption assembly 4 includes a double-sided magnetic strip 8 movably disposed within the holding handle 2. A magnetic attraction member 9 is disposed within the holding handle 2 to drive the double-sided magnetic strip 8 to be drawn out from the holding handle 2, thereby driving the double-sided magnetic strip 8 to adsorb the suture needle falling on the surface of the operating table. A reset member 10 is disposed on one side of the holding handle 2 to drive the double-sided magnetic strip 8 to reset. A positioning member 11 is disposed on one side of the holding handle 2 to position the double-sided magnetic strip 8 after it is drawn out.

[0046] Please refer to Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 9 , Figure 10, the magnetic component 9 includes a storage groove 91 formed in the holding handle 2. The double-sided magnetic strip 8 is movably arranged in the storage groove 91. A rectangular groove 92 is formed in the holding handle 2. One end of the double-sided magnetic strip 8 is slidably and penetratively arranged in the rectangular groove 92. A magnetic attraction plate 93 is arranged at one end of the double-sided magnetic strip 8 close to the rectangular groove 92. One side of the magnetic attraction plate 93 close to the holding handle 2 is attached to the holding handle 2. A driving handle 94 is arranged on the side of the magnetic attraction plate 93 away from the double-sided magnetic strip 8. Fixed magnets 95 are arranged at both ends of the holding handle 2. The fixed magnets 95 at both ends of the holding handle 2 are adsorbed on one side of the operating table. Then, the driving handle 94 is pulled. When the driving handle 94 is pulled, the driving handle 94 will drive the magnetic attraction plate 93 on its side, so that the magnetic attraction plate 93 is separated from the holding handle 2. When the magnetic attraction plate 93 moves together with the driving handle 94, the double-sided magnetic strip 8 arranged on one side of the magnetic attraction plate 93 will be pulled out together with the magnetic attraction plate 93, so that the double-sided magnetic strip 8 slides in the rectangular groove 92. Its function is that when the suture needle falls on the edge of the operating table, it can be adsorbed by the double-sided magnetic strip 8 to prevent the suture needle from falling to the ground.

[0047] Please refer to Figure 3 , Figure 9 , Figure 10 , the reset component 10 includes a reset shaft 101 rotatably arranged in the holding handle 2, and the reset shaft 101 penetrates the storage groove 91. One end of the double-sided magnetic strip 8 away from the magnetic attraction plate 93 is arranged on the outer side of the reset shaft 101, and the double-sided magnetic strip 8 is wound around the outer side of the reset shaft 101. A hairspring 102 is arranged at one end of the holding handle 2 away from the connecting pipe 51. The other end of the hairspring 102 is arranged on the outer side of the reset shaft 101. When the positioning ratchet tooth 113 is separated from the restriction on the positioning ratchet wheel 111, the hairspring 102 will control the rotation of the reset shaft 101. When the reset shaft 101 rotates, the reset shaft 101 will wind up one end of the double-sided magnetic strip 8 through it, so that the double-sided magnetic strip 8 is retracted into the storage groove 91. Its function is that it can automatically retract the double-sided magnetic strip 8.

[0048] Please refer to Figure 2 , Figure 3 , Figure 9 , Figure 11, the positioning member 11 includes a positioning ratchet wheel 111 provided at one end of the reset shaft 101 close to the mainspring 102. A positioning shaft 112 is rotatably provided at one end of the holding handle 2 away from the connecting pipe 51. A positioning ratchet tooth 113 that cooperates with the positioning ratchet wheel 111 is provided on the outer side of the positioning shaft 112. A positioning torsion spring 114 is provided on the outer side of the positioning shaft 112. One end of the positioning torsion spring 114 away from the positioning shaft 112 is provided inside the holding handle 2. A positioning handle 115 is provided at one end of the positioning shaft 112 away from the holding handle 2. When it is desired to retract the double-sided magnetic strip 8 into the storage groove 91, by rotating the positioning handle 115, the positioning handle 115 drives the positioning shaft 112 to rotate. When the positioning shaft 112 rotates, the positioning ratchet tooth 113 provided on the outer side of the positioning shaft 112 will rotate together with the positioning shaft 112, so that the positioning ratchet tooth 113 releases the control of the positioning ratchet tooth 113, enabling the reset shaft 101 at the center of the positioning ratchet wheel 111 to rotate. The positioning torsion spring 114 provided on the outer side of the positioning shaft 112 can continue to catch on the positioning ratchet wheel 111 when the double-sided magnetic strip 8 is pulled out, so that the double-sided magnetic strip 8 will not be immediately retracted. Its function is to prevent the double-sided magnetic strip 8 from being immediately retracted under the action of the mainspring 102 after being pulled out, thus affecting the adsorption force of the double-sided magnetic strip 8.

[0049] During use, when the suture needle drops during handover or suture and it is necessary to search in the gap of the operating table, the medical staff holds the holding handle 2, inserts one end of the connecting pipe 51 close to the needle-searching magnetic ring 1 into the gap of the operating table, and keeps the connecting pipe 51 in an upright state. The two connecting plates 52 provided at one end of the connecting pipe 51 cooperate with the baffle 53 to prevent the needle-searching magnetic ring 1 from directly adsorbing on the iron frame at the bottom of the operating table. When the medical staff moves the needle-searching magnetic ring 1 by holding the holding handle 2 and cooperating with the connecting pipe 51, when the needle-searching magnetic ring 1 approaches the suture needle, the suture needle will directly adsorb on the outer side of the needle-searching magnetic ring 1. After the suture needle adsorbs on the outer side of the needle-searching magnetic ring 1, the needle-searching magnetic ring 1 adsorbed with the suture needle can be directly lifted by holding the holding handle 2 and the connecting rod;

[0050] When the needle-seeking magnetic ring 1 adsorbs the suture needle and the suture needle is stuck in the gap of the operating table and cannot move directly with the needle-seeking magnetic ring 1, under the movement of the holding handle 2, the needle-seeking magnetic ring 1 will disengage from between the baffle 53 and the connecting pipe 51, and drive the auxiliary plate 65 on one side of it to stay at the position where the suture needle is stuck together with it. When the auxiliary plate 65 is separated from the baffle 53, the auxiliary rod 64 arranged on one side of the auxiliary plate 65 will stay at the position where the suture needle is stuck together with the auxiliary plate 65, so that the guiding rope 63 at one end of the auxiliary rod 64 is pulled. When the end of the guiding rope 63 close to the auxiliary rod 64 stays at the position of the suture needle and is pulled, the winding wheel 62 will start to rotate under the action of the guiding rope 63, so that the guiding rope 63 is pulled out as the holding handle 2 moves. When the winding wheel 62 rotates, the guiding shaft 61 arranged at its axis will rotate together with the winding wheel 62, so that the guiding ratchet 67 arranged outside the guiding shaft 61 rotates together with the guiding shaft 61. When the guiding rope 63 is pulled out, if the winding wheel 62 is close to the suture needle, the guiding torsion spring 66 arranged outside the guiding shaft 61 will control the rotation of the winding wheel 62 and wind up the guiding rope 63 through the winding wheel 62. The rotating shaft 68 arranged in the holding handle 2 can cooperate with the rotating torsion spring 610 arranged outside it to control the guiding ratchet 69 not to contact the guiding ratchet 67 without external force, so as to avoid affecting the winding of the guiding rope 63 by the winding wheel 62;

[0051] When the needle-seeking magnetic ring 1 adsorbs the suture needle stuck in the gap of the operating table and it is necessary to find the position of the suture needle through the guiding rope 63, by pressing the extrusion handle 75, the extrusion handle 75 moves downward. When the extrusion handle 75 moves downward, the extrusion rod 72 arranged at the bottom of the extrusion handle 75 will slide in the holding handle 2 and the fixed block 71, and the limiting plate 73 arranged outside the extrusion rod 72 will move together with the extrusion rod 72. When the extrusion rod 72 moves downward, the extrusion rod 72 will squeeze the end of the guiding ratchet 69 away from the rotating shaft 68, so that the guiding ratchet 69 is stuck on the guiding ratchet 67, so that the guiding rope 63 can no longer be pulled out from the winding wheel 62, and then the guiding rope 63 is tightened, so that the pulled-out part of the guiding rope 63 is exposed under the vision of the medical staff. Then, follow the guiding rope 63 to find the position of the needle-seeking magnetic ring 1, and then find the suture needle, and then take it out through relevant medical devices. The extrusion spring 74 arranged at the bottom of the limiting plate 73 can control the extrusion rod 72 to reset in time when the extrusion handle 75 is not affected by external force, and the limiting plate 73 can cooperate with the fixed plate to prevent the extrusion rod 72 from slipping off due to the excessive elastic force of the extrusion spring 74, affecting subsequent use;

[0052] Before medical staff perform a surgery, in order to prevent the suture needle from falling onto the operating table and then onto the ground, resulting in a large search area, the fixed magnets 95 at both ends of the holding handle 2 are adsorbed on one side of the operating table. Then, the driving handle 94 is pulled. When the driving handle 94 is pulled, the driving handle 94 will drive the magnetic adsorption plate 93 on one side of it, causing the magnetic adsorption plate 93 to disengage from the holding handle 2. When the magnetic adsorption plate 93 moves together with the driving handle 94, the double-sided magnetic strip 8 provided on one side of the magnetic adsorption plate 93 will be pulled out together with the magnetic adsorption plate 93, causing the double-sided magnetic strip 8 to slide in the rectangular groove 92. Then, the pulled-out double-sided magnetic strip 8 is attached around the operating table, causing the double-sided magnetic strip 8 to be adsorbed on the outside of the operating table. When it is desired to retract the double-sided magnetic strip 8 into the storage groove 91, by rotating the positioning handle 115, the positioning handle 115 drives the positioning shaft 112 to rotate. When the positioning shaft 112 rotates, the positioning ratchet teeth 113 provided on the outside of the positioning shaft 112 will rotate together with the positioning shaft 112, causing the positioning ratchet teeth 113 to disengage from the control of the positioning ratchet teeth 113, enabling the reset shaft 101 at the center of the positioning ratchet 111 to rotate. The positioning torsion spring 114 provided on the outside of the positioning shaft 112 can continue to be stuck on the positioning ratchet 111 when the double-sided magnetic strip 8 is pulled out, so that the double-sided magnetic strip 8 will not be immediately retracted. When the positioning ratchet teeth 113 disengage from the restriction of the positioning ratchet 111, the clockwork spring 102 will control the reset shaft 101 to rotate. When the reset shaft 101 rotates, the reset shaft 101 will wind up one end of the double-sided magnetic strip 8 through it, so that the double-sided magnetic strip 8 is retracted into the storage groove 91, completing the reset of the double-sided magnetic strip 8 and facilitating subsequent use.

[0053] Embodiment 2: Please refer to Figure 12 , the present invention provides a technical solution:

[0054] Different from Embodiment 1: A screw rod 12 is provided on the side of the auxiliary plate 65 close to the auxiliary rod 64. A threaded groove 13 matching the screw rod 12 is opened in the auxiliary rod 64. The auxiliary plate 65 is threadedly connected to the auxiliary rod 64 through the screw rod 12 and the threaded groove 13. When the magnetic needle-seeking ring 1 needs to be replaced due to the reduction of its magnetic force, by rotating the auxiliary plate 65, the auxiliary plate 65 drives the screw rod 12 to rotate, causing the screw rod 12 to disengage from the threaded groove 13 in the auxiliary rod 64, so as to facilitate the removal of the magnetic needle-seeking ring 1, and then it can be replaced. Its function is to facilitate the replacement of the magnetic needle-seeking ring 1.
