Description
Technical field
The present invention relates to medical instruments field, particularly a kind of scalable circular retractor.
Background technology
Retractor is widely used in surgical clinical operation, such as gynecological surgery, prostatectomy, anorectum department operation, ear nose larynx
Section's operation, Plastic renovation operation, hand and foot surgery operation, paediatrics operation, neurosurgery etc.；The retractable skin of retractor,
It hypodermis, muscle and manadesma etc., can fully appear surgical field of view, save about 1~2 assistant, and substantially mitigate assistant
Labor intensity.Existing domestic retractor is mostly metal retractors, and operation is complex, and body is larger and comparatively heavy；
Foreign countries are mostly plastic cement type retractor using retractor, and lighter in weight, body is smaller, and operation is more convenient, but external use
Plastic cement type retractor can not adjusting size.
The content of the invention
The scalable circular retractor adjustable and easy to use it is an object of the invention to provide a kind of size.
The purpose of the present invention is achieved through the following technical solutions：A kind of scalable circular retractor, it is included more than two panels
Blade, blade are in turn connected to form loop configuration, at least one in loop configuration at tie point connected by adjustment structure with reality
The regulation of existing retractor size；Adjustment structure includes locking piece and the adjustment hole being divided on adjacent blades, two panels blade
Adjustment hole is connected after mutually overlapping by locking piece.
For prior art, the advantage of the invention is that：
1. the regulation of retractor size can be realized；
2. scalable circular retractor remains the advantages of plastic cement type retractor is in light weight, body is small；
3. blade is provided with breach, the drag hook with silica gel rope of arranging in pairs or groups, it can realize that the quick traction of tissue is fixed.

Embodiment
Present invention is described in detail with reference to Figure of description and embodiment：
As shown in figs. 1-11：A kind of scalable circular retractor, it is sequentially connected shape including two panels with blade 1, blade 1
Circularize structure, at least one in loop configuration at tie point connected by adjustment structure to realize the regulation of retractor size；
Adjustment structure includes locking piece and the adjustment hole 2 that is divided on adjacent blades 1, after the adjustment hole 2 of two panels blade 1 is mutually overlapping
Connected by locking piece.The locking piece is the bolt 31 and nut 32 to cooperate.
It is non-circular boss 33 to have one section of section on the bolt 31.Non-circular can be square, ellipse, hexagon
Etc. shape, the non-circular boss of screw bottom can match somebody with somebody the adjustment hole 2 on hing straps, and bolt is with nut one when preventing rotating nuts
Rise and rotate.
As Figure 1-4：Other tie points between the blade 1 are hinged by articulated structure.
Articulated manner includes following two embodiments：
Embodiment 1
As Figure 1-3:The articulated structure includes the rotating shaft 81 being arranged on a blade 1 and is arranged on another
Spacing hole 82 on blade 1, is provided with limit card block 83 at the top of rotating shaft 81, and the width of spacing hole is less than the diameter of rotating shaft 81 and spacing
The length in hole 82 is more than the diameter of rotating shaft 81, and the profile and limit card block 83 of spacing hole 82 are corresponding and are set at the middle part of spacing hole 82
Have and 81 corresponding profile of rotating shaft.In use, bar shaped limit card block 83 is passed through into spacing hole 82, make limit card block 83 and rotating shaft 81
Moving blade 1 after cooperation, make bar shaped limit card block 83 and the mutual dislocation of spacing hole 82；Two adjacent camber line blades so can be achieved
Dismounting and connection, and facilitate the regulation of retractor size.
Embodiment 2
As shown in Figure 4:The articulated structure includes being arranged on the through hole 91 of a blade tip, is arranged on another blade
The fixing threaded hole 92 of end and the screw rod 93 coordinated through through hole 91 and with the screw thread of fixing threaded hole 92.
As shown in Figure 11-Figure 5：The tie point of the present invention is attached by adjustment structure.
As shown in figs. 1-11：If the outer edge of blade 1 is provided with arterial highway breach 4.The bottom of the breach, which is provided with, is located at leaf
The groove 7 of the outer edge of piece 1, the groove extend along the outer edge of blade 1.It also includes drag hook 51 and is arranged on the afterbody of drag hook 51
And the silica gel rope 52 coordinated with breach.
As shown in figs. 12-14：It can be used for blocking silica gel rope if the outer edge of blade 1 is provided with the design of arterial highway breach 4, make its unlikely
In slippage；During use：Somewhat unscrew nut, interlobate mutually motion can be achieved, adjust the size of retractor, adjust to suitable
Nut is tightened during size.
