Problems solved by technology

[0003] The purpose of the present invention is to design a retractor for a series of problems such as small application range, large volume, large number of parts, occupying a lot of operation space, affecting the doctor's station operation, and the pulling part cannot be moved arbitrarily at the bedside. This kind of retractor has a simple structure, can be applied to any part of the traction, is small in size, and the device of the traction hook plate does not protrude out of the operating bed, and does not affect the operation of the surgeon's standing operation.

Embodiment 1

[0029] like figure 1 , 2 shown.

[0030] A surgical retractor with a built-in pull chain rope, including a column 1 and a hook plate 2. The column 1 can be directly connected to the side of the operating bed (such as using a plug-in type, a bolt-tight type, etc.), and can also be connected to the operating table through a fixing frame 3. The bedside realizes the lifting type to be connected, and the structure of the fixed frame 3 is as follows: figure 1 , 2 As shown or the same as the fixed frame of the existing retractor, the present embodiment takes the lifting structure as an example to illustrate, the lower end of the column 1 is inserted and fixed in the fixed frame 3, and the hook plate 2 is connected by a universal Pin 12 links to each other with one end of the chain as one of pulling chain rope 13 structural forms, and the other end of chain walks around the sprocket wheel 5 as driving device 22 and stretches in the cavity of column 1, and the sprocket shaft of desc...

Embodiment 2

[0034] like image 3 , 4 , 5 shown.

[0035] A surgical retractor with a built-in pull chain rope, including a column 1 and a hook plate 2. The column 1 can be directly fixedly connected to the side of the operating bed (such as using a plug-in type, a bolt-tight type, etc.), or it can be connected to the side of the operating bed through a fixed frame 3. The side of the operating bed is connected in a lifting manner, and the structure of the fixing frame 3 is as follows: figure 1 , 2 As shown or the same as the fixed frame of the existing retractor, the present embodiment takes the lifting structure as an example to illustrate, the lower end of the column 1 is inserted and fixed in the fixed frame 3, and the pulling chain rope 13 is a traction belt , the hook plate 2 is connected to one end of the traction belt, and the other end of the traction belt (which can be a track or a toothed belt with protrusions on both sides) passes through the driving roller 14 and the driv...

Embodiment 3

[0039] Such as Image 6 , 7 shown.

[0040] A surgical retractor with a built-in pull chain rope, including a column 1 and a hook plate 2. The column 1 can be directly fixedly connected to the side of the operating bed (such as using a plug-in type, a bolt-tight type, etc.), or it can be connected to the side of the operating bed through a fixed frame 3. The side of the operating bed is connected in a lifting manner, and the structure of the fixing frame 3 is as follows: figure 1 , 2 As shown or the same as the fixed frame of the existing retractor, the present embodiment takes the lifting structure as an example to illustrate, the lower end of the column 1 is inserted and fixed in the fixed frame 3, the hook plate 2 and the pulling chain rope 13 are connected at one end, and the other end of the pulling chain rope 13 is stretched into the cavity of the column 1 through the driving device 22 installed on the column 1, and the pulling chain rope 13 can be the same traction b...

Abstract

The invention discloses an operation retractor with a draw-off chain rope, comprising a stand column (1) and a hook plate (2), wherein the stand column (1) is in a fixed structure or a liftable structure; the stand column (1) is directly connected with an operating bed or is connected with the operating bed through a fixed mount (3). The operation retractor is characterized in that the hook plate (2) is connected with one end of the draw-off chain rope (13), the other end of the draw-off chain rope (13) stretches into the cavity of the stand column (1) through a driving device (22) installed on the stand column (1). The invention has simple structure, small volume, no occupied space except the operating bed and good operation field of view, can randomly move on the side of the operating bed according to demands, and can be used for retraction of operation incisions at any part of human trunk.

Description

technical field [0001] The present invention relates to a medical device, especially a retractor used in surgery that can replace the manual retraction of the incision so that the surgical field can be fully exposed, specifically a pull chain suitable for various operations Rope built-in surgical retractor. Background technique [0002] At present, in the operation of straight abdominal incision, such as general surgery, urology, obstetrics and gynecology, in order to obtain an ideal surgical field, it is necessary to keep the opened abdomen in a good retraction state; also in the operation of thorax, back and spine, etc. The incision also needs to be retracted. The existing method one is to rely on the surgical assistant to pull the incision apart from both sides with pull hooks, which is poor in effect and labor-intensive. People have invented various abdominal operation retractors to replace artificial traction for this reason, and people are liberated from heavy physica...
