Abstract
This utility model relates to a kind of artificial total hip arthroplasty acetabular bone lower edge cold light source type drag hook, comprise handle, connecting rod, power supply, cold light source luminous body, adapter and drag hook, wherein connecting rod one end and handle hinged, the other end is connected with adapter by bolt, drag hook rear end face is connected with adapter, front end face is curved, and uniform fastening teeth, handle, connecting rod are hollow-core construction, power supply is positioned at handle inner, and be connected with cold light source luminous body by wire, wire is positioned at handle and connecting rod is inner, and is embedded in respectively in adapter and connecting rod.This novel one side has good pawl holding effect fruit, acetabulum injuries can not be caused, on the other hand can according to use needs, handle position is adjusted flexibly, cause blocking the doctor visual field after avoiding drag hook location, contribute to the efficiency improving operation, meanwhile also there is good illuminating effect, and illumination can not produce waste heat simultaneously, thus avoid heat of light source and cause the damage to patient.
Description
Technical field
This utility model relates to a kind of artificial total hip arthroplasty acetabular bone lower edge cold light source type drag hook, belongs to bone surgery apparatus field.
Background technology
At present in the operation carrying out artificial total hip arthroplasty, main employing is Huffman formula drag hook clinically, but this hook structure can not coordinate completely with acetabular bone physiological structure, thus it is unstable to cause drag hook location, or cause acetabular bone structural damage, simultaneously, this hook structure mostly is monolithic construction, it is stiff to use, can not need to adjust flexibly according to operation, thus often cause drag hook to block the phenomenon in the doctor visual field, be unfavorable for carrying out of operation, existing Huffman formula drag hook does not also possess illumination functions simultaneously, also the unsharp drawback in the doctor visual field in operation is caused further, although also have on some drag hooks at present and have employed luminaire, but these luminaires can produce more heat in use, thus cause burning to patient, therefore in the urgent need to developing the needs that a kind of novel artificial total hip arthroplasty containing acetabular bone draw hook uses with satisfied reality.
Summary of the invention
For the deficiency that prior art exists, this utility model provides a kind of artificial total hip arthroplasty acetabular bone lower edge cold light source type drag hook, this new structure is simple, easy to use, drag hook has good pawl holding effect fruit on the one hand, and can not acetabulum injuries be caused, on the other hand can be according to actual needs, handle position is adjusted flexibly, blocking the doctor visual field is caused after avoiding drag hook location, contribute to the efficiency improving operation, meanwhile also there is good illuminating effect, and illumination can not produce waste heat simultaneously, thus avoid heat of light source and cause the damage to patient.
To achieve these goals, this utility model realizes by the following technical solutions:
A kind of artificial total hip arthroplasty acetabular bone lower edge cold light source type drag hook, comprise hands handle, connecting rod, power supply, cold light source luminous body, adapter and drag hook, wherein connecting rod one end and handle hinged, the other end is connected with adapter by bolt, drag hook rear end face is connected with adapter, front end face is curved, and uniform fastening teeth, hands handle, connecting rod is hollow-core construction, power supply is positioned at handle inner, and be connected with cold light source luminous body by wire, wire is positioned at handle and connecting rod is inner, cold light source luminous body at least two, and be embedded in adapter and connecting rod respectively, and the cold light source luminous body at adapter place is positioned at adapter lower surface.
Further, described light source luminescent body all independently establishes gauge tap to be connected with power supply.
Further, it is hinged that described connecting rod and handle pass through ratchet.
This new structure is simple, easy to use, drag hook has good pawl holding effect fruit on the one hand, and can not cause acetabulum injuries, on the other hand can be according to actual needs, handle position is adjusted flexibly, cause blocking the doctor visual field after avoiding drag hook location, contribute to the efficiency improving operation, meanwhile also there is good illuminating effect, and illumination can not produce waste heat simultaneously, thus avoid heat of light source and cause the damage to patient.
Accompanying drawing explanation
This utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is this new structure schematic diagram.
Fig. 2 is the connection diagram of this novel teeth consolidating and drag hook.
Detailed description of the invention
The technological means realized for making this utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth this utility model further.
A kind of artificial total hip arthroplasty acetabular bone lower edge cold light source type drag hook as described in Figure 1, comprises handle 1, connecting rod 2, power supply 3, cold light source luminous body 4, adapter 5 and drag hook 6.
In the present embodiment, connecting rod 2 one end and handle 1 hinged, the other end is connected with adapter 5 by bolt, drag hook 6 rear end face is connected with adapter 5, front end face is curved, and uniform fastening teeth 7, handle 1, connecting rod 2 are hollow-core construction, it is inner that power supply 3 is positioned at handle 1, and be connected with cold light source luminous body 4 by wire 8, wire 8 is positioned at handle 1 and connecting rod 2 is inner, cold light source luminous body 4 at least two, and be embedded in respectively in adapter 5 and connecting rod 2, and the cold light source luminous body at adapter 5 place is positioned at adapter 5 lower surface.
In the present embodiment, described light source luminescent body 4 all independently establishes gauge tap 9 to be connected with power supply 3, and connecting rod 2 is hinged by ratchet 10 with handle 1.
During this novel use, structure is simple, easy to use, and drag hook has good pawl holding effect fruit on the one hand, and can not acetabulum injuries be caused, according to actual needs, handle position can be adjusted flexibly on the other hand, after avoiding drag hook location, cause blocking the doctor visual field, contribute to the efficiency improving operation, meanwhile also there is good illuminating effect, and illumination can not produce waste heat simultaneously, thus avoid heat of light source and cause the damage to patient.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed this utility model.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
