Abstract
The utility model discloses an incision retractor, which comprises a first retraction ring which is positioned at the upper part and a second retraction ring which is positioned at the lower part, wherein the first and the second retraction rings are connected with each other through a cannular elastic membrane. The incision retractor disclosed by the utility model can be placed at a surgical incision during the operation, the elasticity of the first and the second retraction rings is utilized to drive the elastic membrane to retract the surgical incision, and accordingly, doctors are facilitated to operate on patients.
Description
Technical field
This utility model relates to the medical apparatus and instruments that a kind of surgical operation is used, and specifically, is a kind of operating otch retractor that is applied to.
Background technology
In surgical operation, behind the operative site otch of doctor the patient, because the contraction of tissue, otch can be closure state.In order to implement operation, the otch stretching is expanded open.Early stage operation is to strut by staff or some metal drag hooks, the tissue injury that this mode exposes limitation and causes because of excessive tractive owing to the effective wound of tractive unbalance stress, even can cause the secondary injury to otch.Meanwhile traditional tractive mode lacks effectively protection to the wound perimeter tissue, has the wound circumference tissue that the possibility of pollution and tumor planting takes place.Patient's wound is caused adverse effect after more.
The utility model content
The technical problems to be solved in the utility model provides a kind of otch retractor, is used for strutting when surgical operation otch, and otch effectively is exposed to the convenient operation of implementing.
In order to solve the problems of the technologies described above, this utility model provides a kind of otch retractor, comprises that superposed first retracts ring and be positioned at second of bottom and retract ring, and described first retracts ring and second retracts the elastica of encircling by tubular and be connected.
Described first retracts ring and/or second retracts and is provided with cavity in the ring.
The cross section of described cavity is circular or quincunx.
Described first cross section that retracts ring is 8 fonts.
Described second retracts the cross section of ring for circular.
Described elastica is connected to described first outside that retracts ring, makes first to retract ring and can overturn to the inside.
Described elastica is connected to described second outside that retracts ring.
Described first retracts ring and second, and to retract the external diameter of ring equal.
Described elastica is connected to described second inboard that retracts ring.
Described first external diameter that retracts ring equates with described second internal diameter that retracts ring.
Otch retractor of the present utility model the time can place the operative incision place in operation, utilizes first to retract ring and second and retract ring resilience and drive elastica operative incision is retracted, thereby makes things convenient for the doctor that the patient is implemented to perform the operation.
Description of drawings
Fig. 1 is portion's view of otch retractor one embodiment of the present utility model;
Fig. 2 is portion's view of another embodiment of otch retractor of the present utility model.
Among the figure: 1. first retract ring, 2. second retract ring, 3. elastica, 4. cavity.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand this utility model and being implemented, but illustrated embodiment is not as to qualification of the present utility model.
As shown in Figure 1, in first embodiment of the present utility model, the otch retractor comprises that superposed first retracts ring 1 and be positioned at second of bottom and retract ring 2, the first and retract ring 1 and second and retract between the ring 2 by elastica cylindraceous 3 connections.Wherein, elastica 3 is connected to first and retracts ring 1 the outside, makes first to retract ring 1 and can overturn to the inside, and elastica 3 is connected to second and retracts ring 2 the outside, and first retracts the external diameter that ring 1 and second retracts ring 2 equates, so that elastica 3 is cylindric, be convenient to processing and manufacturing and use.
During use, retract ring 2 with second and flatten, fill in from operative incision, unclamp then, second retracts ring 2 recovers circular under self elastic force effect.By the direction of arrow among Fig. 1 inwardly upset first retract ring 1, make the top of elastica 3 be wrapped in first and retract on the ring 1, up to the elastica 3 that stays appropriate length.At this moment, retract ring 1 and second first and retract under the support of ring 2, elastica 3 is also opened and is cylindric or the approximate circle tubular, thereby otch is retracted, and is convenient to the doctor and implements operation.Stir the direction of motion that more meets staff to the inside, firmly more convenient.Otch retractor of the present utility model also has the effect of protection otch simultaneously.
As shown in Figure 2, in second embodiment of the present utility model, and elastica 3 is connected to second and retracts ring 2 inboard, and first external diameter and second that retracts ring 1 retracts the internal diameter of ring 2 and equates that it is cylindric that elastica 3 can be equally, is convenient to processing and manufacturing and use.And also being also advantageous in that of this structure when packing and transportation, can all be wrapped in elastica 3 first to retract on the ring 1, is that first retracts on the ring 1 and retract ring 2 covers with second, and its volume is little, and Stability Analysis of Structures is convenient to packing and transportation.
As depicted in figs. 1 and 2, first retracts ring 1 and/or second retracts ring and cavity 4 can be set in 2, promptly first retracts ring 1 and/or second to retract ring 2 be hollow, can make first to retract ring 1 and/or second and retract ring 2 and have better elasticity like this.The cross section of cavity 4 is circular, also can be quincuncial, can also be other shape.
First retracts ring 1 cross section is preferably 8 fonts, upset during more convenient like this uses, and overturn and can oppositely not throw off the reliability height voluntarily after putting in place.And second retract circular or other shape of ring 2 cross section.
The above embodiment is the preferred embodiment that proves absolutely that this utility model is lifted, and protection domain of the present utility model is not limited thereto.Being equal to that those skilled in the art are done on this utility model basis substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
