Description
Technical field
The utility model is used for technical field of medical instruments, particularly relates to a kind of Minimally Invasive Surgery drag hook device.
Background technology
Along with the development of society's science and technology and the progress of medical level, Minimally Invasive Surgery has obtained development in an all-round way. Compared with traditional operation, it is little that Minimally Invasive Surgery has wound, and pain is light, recovers fast, and the hospital stays is short, and the advantage such as intraoperative hemorrhage is few. But compared with traditional operation, Minimally Invasive Surgery owing to being the operation technique relying on chamber mirror and limited small holes to implement complexity, so Minimally Invasive Surgery is had higher requirement for operative doctor. Nowadays the apparatus used in all kinds of Minimally Invasive Surgery is all so that the histoorgan in body is implemented accurate operation and designed by patient in vitro.
But in prior art, the Minimally Invasive Surgery instrument for atrial stretch in cardiac surgery operation but has no report.
Practical novel content
For solving the problem, the utility model provides a kind of structure simple, and atrial stretch is certain, is convenient to the Minimally Invasive Surgery drag hook device of operation technique.
The utility model solves the technical scheme that its technical problem adopts: a kind of Minimally Invasive Surgery drag hook device, comprise anchor, sleeve pipe, the interior bar that can be set in described sleeve pipe and the drag hook that the described lower end of interior bar can be contained in, have in described anchor and cross hole for what described sleeve pipe passed, some drag hook teeth that described drag hook comprises Connection Block and stretches out to side by described Connection Block, each described drag hook tooth is all bent to form and is upturned the hook shape embracing atrium, each described drag hook tooth forms a line on described Connection Block, adjacent drag hook between cog leaves gap, whole drag hook is rake shape, described Connection Block is provided with threaded hole, the lower end of described interior bar is provided with the outside screw that can screw in described threaded hole.
The improvement being further used as technical solutions of the utility model, described anchor is provided with spherical chamber at the described middle part crossing hole, is provided with the rotation ball that can rotate in described spherical chamber in spherical chamber, described rotation ball is offered for the through hole that described sleeve pipe passes.
The improvement being further used as technical solutions of the utility model, the top of described sleeve pipe is provided with the limited block crossed out.
The improvement being further used as technical solutions of the utility model, the top of described interior bar is provided with lever.
The beneficial effects of the utility model: when operating in art, are first inserted in sleeve pipe by interior bar and are combined into drag hook bar. Anchor is fixed on the body surface wall of the chest, and make the small holes that the wall of the chest is just being opened by hole excessively of anchor, the drag hook bar combined is deep in thoracic cavity by anchor, from another minimally invasive hole that another side is bigger, drag hook is sent into thoracic cavity, and is fixed on the lower edge of deep interior bar. After combination, drag hook is arrived by interior bar to be needed to lead the position (edge, atrium to for cutting) drawn, and operative doctor is operated in vitro by interior bar, controls the direction of drag hook and leads the power drawn backward. The utility model adopts has the drag hook of some drag hook teeth, and has space between drag hook tooth, lead draw time, some atrial tissue can enter in space, so fixed effect is certain, not easily slippage. Due to atrial wall fixing in several directions, so fixed effect is certain, not easily slippage, atrial stretch is certain, is convenient to operation technique.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is structural representation after the utility model assembly;
Fig. 2 is the utility model fixed rack structure schematic diagram;
Fig. 3 is the utility model hook structure schematic diagram.
Embodiment
Referring to figs. 1 through Fig. 3, that show the concrete structure of the better embodiment of the utility model. The constructional feature of each element of the utility model will be described in detail below, if and when being described to direction (upper and lower, left and right, before and after), it is taking the structure shown in Fig. 1 as reference describes, but actual user of the present utility model is to being not limited thereto.
The utility model provides a kind of Minimally Invasive Surgery drag hook device, comprise anchor 1, sleeve pipe 2, the interior bar 3 that can be set in described sleeve pipe 2 and the drag hook 4 that described interior bar 3 times ends can be contained in, have in described anchor 1 and cross hole for what described sleeve pipe 2 passed, the top of described sleeve pipe 2 is provided with the limited block 21 crossed out, with control sleeve pipe 2 wear into the length in hole, some drag hook teeth 42 that described drag hook 4 comprises Connection Block 41 and stretches out to side by described Connection Block 41, each described drag hook tooth 42 is all bent to form and is upturned the hook shape embracing atrium, each described drag hook tooth 42 forms a line on described Connection Block 41, gap is left between adjacent drag hook tooth 42, whole drag hook 4 is in rake shape, the utility model adopts the drag hook 4 with some drag hook teeth 42, and have space between drag hook tooth 42, lead draw time, some atrial tissue can enter in gap, so fixed effect is certain, not easily slippage. due to atrial wall fixing in several directions, so fixed effect is certain, not easily slippage, atrial stretch is certain, is convenient to operation technique. described Connection Block 41 is provided with threaded hole 43, and the top of described interior bar 3 is provided with lever 31, and the lower end of described interior bar 3 is provided with the outside screw that can screw in described threaded hole 43. or Connection Block 41 is provided with bayonet socket, the lower end of interior bar 3 is provided with and can embed the interior card convex to be connected fast with drag hook blade 4 of bayonet socket.
