Description
Affiliated technical field
This utility model belongs to medical apparatus and instruments, the direct-view Wicresoft operation on biliary tract drag hook of using especially for operation on biliary tract.
Background technology
Gallbladder removal is at present with following several method excision: 1, traditional cholecystectomy, i.e. CC operation is the basis of other operation of biliary tract, also is as the highest standard of judging the operation on biliary tract curative effect, has established " goldstandard " status of operation on biliary tract.But exist operation wound big, painful many, recover slow, postoperative pain at a specified future date obviously and longer duration, complication is more, incisional scar greatly and influence defectives such as attractive in appearance.2, through laparoscopic cholecystectomy, i.e. LC operation, this operation has reached the level of minimally invasive surgery from the wound angle.High in technological content, be the model of endoscopic surgery, be a kind of advanced person's therapeutic treatment technical method.But also exist endoscope and corresponding apparatus output investment ratio bigger, medical treatment cost and expense height.Artificial pneumoperitoneum.Must general anesthesia.Operate under the two-dimensional field of view, the technique drill cycle is long and than higher operation risk.3, direct-view Wicresoft operation on biliary tract is through looking at down miniature incision straight, the direct-view minimally invasive surgery operating technology of at real three-dimensional space, implement that triangle area separates with cholecyst bed Wicresoft, cystic duct, cystic artery and biliary tract Wicresoft operating.This technology combines the advantage through laparoscopic cholecystectomy and little otch cholecystectomy perfectly, and is safe and reliable.MBS has reached Wicresoft's effect of LC.But otch is more little, and the difficulty of operation and risk just increase significantly.Although the MBS operation has complete ideal operating theater instruments, instrument and complete operation method and skill, but the visual field is narrow and small, and the patient is generally more clearly, and the assistant when assisting visual sense poor, general assisting operation will be finished under patient's requirement, and the operation that affects patient's operation and assistant cooperates.Image in the operation can not be compiled, and it is not enough that the teaching aspect just seems.
Summary of the invention
The purpose of this utility model is in order to solve the problem of above existence, and designs the direct-view Wicresoft operation on biliary tract drag hook of little, painful less, the safe and reliable band photographic head of a kind of wound.
This utility model is achieved in that it is to be provided with groove on the vertical pulling hook of Zola's hook support one end of original surgery tractor that is made of left and right drag hook support, tooth bar, adjusting rod, drag hook pawl, rotating shaft, on groove, inserted the drag hook plate washer, on the drag hook plate washer, be provided with photographic head, be provided with several holes on the sidewall of vertical pulling hook, the hole is provided with light source.The drag hook plate washer is the L type, and Zola's hook support and right drag hook support be not for isometric, and right drag hook support is shorter than Zola hook support.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is that the A of vertical pulling hook among this utility model Fig. 1, drag hook plate washer and photographic head is to view.
Accompanying drawing 3 is that the B of vertical pulling hook among this utility model Fig. 1 is to view.
Accompanying drawing 4 is that the C of drag hook pawl among this utility model Fig. 1 is to view.
Among the figure: 1-vertical pulling hook, 2-groove, 3-drag hook plate washer, 4-photographic head, 5-drag hook pawl, the right drag hook support of 6-, 7-tooth bar, 8-adjusting rod, 9-rotating shaft, 10-Zola hook support, 11-light source, 12-hole, 13-photographic head plug.
The specific embodiment
As shown in the figure: this utility model is to be provided with groove 2 on the vertical pulling hook 1 of Zola's hook support 10 1 ends of original surgery tractor that is made of Zola's hook support 10, right drag hook support 6, tooth bar 7, adjusting rod 8, drag hook pawl 5, vertical pulling hook 1, rotating shaft 9, on groove 2, inserted drag hook plate washer 3, on drag hook plate washer 3, be provided with photographic head 4, on the sidewall of vertical pulling hook 1, be provided with several holes 12, hole 12 is provided with light source 11, and photographic head 4 one ends are connected with photographic head plug 13.Drag hook plate washer 3 is the L type.Right drag hook support 6 and Zola's hook support 10 be not for isometric, and right drag hook support 6 is shorter than Zola hook support 10.
This utility model is owing to be provided with drag hook plate washer 3 at vertical pulling hook 1 place, and drag hook plate washer 3 is provided with photographic head 4, is provided with light source 11 on the sidewall of vertical pulling hook 1, so can clearly observe the situation in the operation in use, is convenient to the surgical staff tacit agreement and cooperates.The wild image of art can be introduced the classroom observation of performing the operation synchronously by navigation system simultaneously.Also the collection of data in the art can be convenient to teaching and scientific research.It is simple in structure, and is easy to use, is worth of widely use.
