Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a human bone reduction forceps. Background Art

[0002] After a fracture occurs, bone pliers are usually used to clamp and fix the fracture, and then fixed with steel plates and screws, so that the bones at both ends of the fracture can be connected. However, existing bone pliers often need to be manually held and fixed when connected to the bones, resulting in the need for multiple people to operate simultaneously when resetting the bones.

[0003] In order to improve the clamping stability of the reduction forceps and the bone, the prior art uses two sets of forceps claws to cooperate with the fastener structure to clamp and fix the bone;

[0004] However, during the use of this type of reduction forceps, it was found that when performing the bone reduction process, it is usually necessary to hold two reduction forceps and work at the same time, and the working coordination is often insufficient. Even during the doctor's reduction work and the process of nailing the steel plate, once the user of any reduction forceps loses strength, the broken bone will be dislocated again under muscle traction, seriously increasing the patient's pain. Summary of the invention

[0005] The purpose of the present invention is to provide a human bone reduction forceps to solve the problem that the reduction forceps in the prior art cannot avoid the broken bones from being dislocated again under the action of muscles when reducing the broken bones.

[0006] To achieve the above-mentioned object, the present invention provides a human bone reduction forceps, comprising a first jaw, a second jaw and a fastener structure, wherein the fastener structure cooperates with the first jaw and the second jaw respectively, so that the first jaw and the second jaw can be connected to two broken bones respectively.

[0007] Also includes docking parts,

[0008] The docking member includes a connecting rod and a docking sleeve, wherein the connecting rod is connected to the first jaw, and the docking sleeve is connected to the second jaw. The connecting rod is connected to the docking sleeve to achieve docking of the first jaw and the second jaw.

[0009] The first jaw and the second jaw respectively fix a section of broken bone under the action of their respective fastener structures, and then cooperate with the doctor to dock the two sections of broken bone to complete the bone reduction work. The docking piece connects the first jaw and the second jaw, so that the first jaw is connected to the second jaw and is located at the same height. When performing the reduction work, after the first jaw and the second jaw are respectively connected and fixed to a section of broken bone, there will be no problem of manually leveling the two sections of broken bone to make them consistent in height. The connecting rod and the docking sleeve are used to connect the first jaw and the second jaw.

[0010] Wherein, the docking member further includes a locking coupling, the locking coupling is fixedly connected to the second clamp jaw, and the locking coupling is matched with the connecting rod.

[0011] The locking coupling is used to improve the connection strength between the second clamp jaw and the docking sleeve.

[0012] Wherein, the docking member further includes a seating seat, which is fixedly connected to the first clamp claw and is arranged on the outer side of the connecting rod.

[0013] The mounting seat is used to improve the connection strength between the first clamp claw and the connecting rod.

[0014] Wherein, the locking coupling includes a reinforcement rod and a butt end provided with a through hole, the reinforcement rod is arranged on the outside of the butt end, and the reinforcement rod connects the butt end and the second clamp claw, the through hole is arranged along the length extension direction of the butt end, and the through hole is matched with the connecting rod.

[0015] The reinforcing rod is fixedly connected to the butt end and the second jaw, so that during the resetting process, no deformation will occur between the first jaw and the second jaw, and the through hole is used to allow the connecting rod to pass through to improve the structural strength.

[0016] Wherein, the placement seat includes a stabilizing plate group and a docking seat, the stabilizing plate group is evenly arranged on the outside of the docking seat, and the docking seat is fixedly connected to the first clamp claw to cooperate with the stabilizing plate group to improve the structural strength of the connecting rod.

[0017] The stabilizing plate group is arranged on the outer side of the docking seat, and the docking seat is used to place the stabilizing plate group, so that the stabilizing plate group can be installed and fixed with the docking seat.

[0018] Wherein, the human bone reduction forceps also include a punching plate, and the punching plate is rotatably connected to the first jaw and the second jaw respectively, so as to facilitate the subsequent punching work on the bone.

[0019] The punching plate is used to punch holes in the bone, thereby effectively improving the convenience of punching during the reduction process.

[0020] Among them, the punching member includes a stabilizing plate, a rotating plate frame and a punching plate frame. The stabilizing plate is hinged to the rotating plate frame and is arranged on the outside of the first clamp jaw and the second clamp jaw. The punching plate frame penetrates the rotating plate frame in the horizontal direction to cooperate with the subsequent punching work on the bone.

[0021] The stabilizing plate is used to install the rotating plate frame. The rotating plate frame cooperates with the stabilizing plate to adjust the punching position. When the punching plate frame is punching, the drill needle passes through, thereby realizing the punching work.

[0022] The human bone reduction forceps of the present invention connect two forceps bodies on the basis of the existing technology, and then in the process of bone reduction, the connection stability between the first forceps jaw and the second forceps jaw is effectively improved by using the connecting rod and the docking sleeve body, thereby solving the problem of easy secondary dislocation of two broken bones during the installation of steel plates.

DETAILED DESCRIPTION

[0031] First embodiment:

[0032] See also Figure 1 and Figure 2 , Figure 1 The figure is a schematic diagram of the axonometric structure of a first embodiment of a human bone reduction forceps. Figure 2 The present invention is a schematic cross-sectional structural diagram of a butt joint member of a first embodiment of a human skeleton reduction forceps.

[0033] The present invention provides a human skeleton reduction forceps: comprising a first jaw 101, a second jaw 102, a fastener structure 103 and a docking piece, wherein the docking piece comprises a connecting rod 104, a docking sleeve 105, a locking coupling and a placement seat;

[0034] According to this specific embodiment, the first jaw 101 and the second jaw 102 respectively clamp and fix a section of broken bone under the action of their respective fastener structures 103. During the bone reduction process, after the two sections of broken bone are aligned, the connecting rod 104 is connected to the docking sleeve 105. Even if the broken bone needs to be perforated and a steel plate is punched, the two sections of broken bone are still maintained at the same horizontal height under the action of the connecting rod 104 and the docking sleeve 105, thereby avoiding secondary dislocation of the bone during the reduction process.

[0035] Among them, the fastener structure 103 cooperates with the first jaw 101 and the second jaw 102 respectively, so that the first jaw 101 and the second jaw 102 can be connected to two sections of broken bones respectively, and the fastener structure 103 is used to limit the opening angles of the first jaw 101 and the second jaw 102 respectively, thereby completing the clamping and fixing of the broken bones.

[0036] Secondly, the connecting rod 104 is connected to the first jaw 101, and the docking sleeve 105 is connected to the second jaw 102. The docking sleeve 105 fits with the connecting rod 104 to achieve the docking of the first jaw 101 and the second jaw 102. The connecting rod 104 is used to dock with the docking sleeve 105. After the doctor completes the initial reduction of the broken bone, the connecting rod 104 is docked with the docking sleeve 105, so that the two sections of the broken bone can be kept aligned under the action of the connected first jaw 101 and the second jaw 102, so as to facilitate subsequent operations such as steel plate insertion.

[0037] Then, the locking coupling includes a reinforcement rod 106 and a docking end 107 with a through hole 108. The reinforcement rod 106 is arranged on the outside of the docking end 107, and the reinforcement rod 106 connects the docking end 107 and the second jaw 102. The through hole 108 is arranged along the length extension direction of the docking end 107, and the through hole 108 is matched with the connecting rod 104. The reinforcement rod 106 is used to improve the connection strength between the second jaw 102 and the docking end 107, so that the connecting rod 104 is aligned with the docking end 107, thereby completing the relatively fixed position relationship between the first jaw 101 and the second jaw 102.

[0038] Finally, the mounting seat includes a stabilizing plate group 201 109 and a docking seat 110. The stabilizing plate group 201 109 is evenly arranged on the outside of the docking seat 110. The docking seat 110 is fixedly connected to the first clamp jaw 101 to cooperate with the stabilizing plate group 201 109 to improve the structural strength of the connecting rod 104. The stabilizing plate group 201 109 is also used to improve the structural strength. The docking seat 110 is used to connect the stabilizing plate group 201 109 and the docking seat 110.

[0039] When using the human bone reduction forceps of this embodiment, the first jaw 101 and the second jaw 102 are first fixed on the two broken bones respectively, and then the two broken bones are manually aligned while the connecting rod 104 is inserted into the docking sleeve 105. When the doctor loosens the two broken bones, the two broken bones will not be dislocated due to the action of muscles, thereby avoiding secondary injury to the patient due to the re-dislocation of the aligned broken bones.

[0040] Second embodiment:

[0041] Based on the first embodiment, please refer to Figure 3 and Figure 4 , Figure 3 is an axonometric structural diagram of a second embodiment of a human bone reduction forceps, Figure 4The present invention is a schematic diagram of the axonometric structure of a punched plate of a second embodiment of a human skeleton reduction forceps.

[0042] The present invention provides a human bone reduction forceps also including a punching plate, wherein the punching plate includes a stabilizing plate 201, a rotating plate frame 202 and a punching plate frame 203. The stabilizing plate 201 is used to connect the rotating plate frame 202 with the first jaw 101 and the second jaw 102. The punching plate frame 203 facilitates the penetration of the drill bit of the electric drill, thereby avoiding secondary damage to the patient's wound by the drill bit on the one hand, and guiding the drilling direction of the drill bit into the bone on the other hand.

[0043] Among them, the punching plate is rotatably connected to the first jaw 101 and the second jaw 102 respectively, so as to facilitate the subsequent drilling of bones. The stabilizing plate 201 is hinged to the rotating plate frame 202 and is arranged on the outside of the first jaw 101 and the second jaw 102. The punching plate frame 203 penetrates the rotating plate frame 202 in the horizontal direction to cooperate with the subsequent drilling of bones. The punching plate is arranged on the outside of the first jaw 101 and the second jaw 102. The punching safety is improved by arranging the punching plate. The stabilizing plate 201 is used to connect the rotating plate frame 202 to the first jaw 101 and the second jaw 102 respectively. The punching plate frame 203 is used to avoid secondary damage to the patient's wound by the drill bit on the one hand, and to guide the drilling direction of the drill bit into the bone on the other hand.

[0044] When using a human bone reduction forceps of this embodiment, after aligning the two broken bones, the rotating plate frame 202 is rotated so that the punching plate frame 203 is aligned with the position where a hole needs to be punched on the bone, and then the drill bit is inserted into the punching plate frame 203 to achieve the drilling work on the bone.

[0045] Third embodiment:

[0046] Based on the first embodiment, please refer to Figure 5 and Figure 6 , Figure 5 It is a schematic diagram of the axonometric structure of a third embodiment of a human bone reduction forceps. Figure 6 The figure is a schematic cross-sectional structural diagram of a butt joint member of a third embodiment of a human bone reduction forceps provided by the present invention.

[0047] The present invention provides a human bone reduction forceps further comprising an adjusting member, wherein the adjusting member comprises a locking protrusion 301 and an elastic member 302. The adjusting member cooperates with the connecting rod 104 and the docking sleeve 105 to adjust the length of the docking member, that is, to adjust the relative distance between the first jaw 101 and the second jaw 102, so as to effectively improve the working range of the reduction forceps of the present application.

[0048] Among them, the adjusting member is respectively arranged on the connecting rod 104 and the docking sleeve 105 to adjust the relative position of the connecting rod 104 and the docking sleeve 105, the locking protrusion 301 is arranged on the side of the connecting rod 104 close to the docking sleeve 105, and the locking protrusion 301 is engaged with the docking sleeve 105 through the elastic member 302. The locking protrusion 301 is used to cooperate with the docking sleeve 105 provided with a plurality of holes, so that the depth of the connecting rod 104 penetrating into the docking sleeve 105 can be adjusted, thereby further improving the application range of the reset clamp.

[0049] When using the human bone reduction forceps of this embodiment, the first jaw 101 and the second jaw 102 are placed at appropriate positions according to the lengths of the two broken bones that need to be reduced. After the two broken bones are manually aligned, the locking protrusion 301 is pressed to adjust the position of the connecting rod 104 inside the alignment sleeve, and the first jaw 101 is loosened at the same time to accommodate the movement of the connecting rod 104. After the movement is completed, the first jaw 101 is fixed to the broken bone again, and then the steel plate is struck. The adjustment part is used to effectively avoid the problem of being unable to use due to different lengths of the broken bones.
