Problems solved by technology

[0004] The purpose of the present invention is to design a retractor for a series of problems such as small applicable range, large volume, large number of parts, occupying a lot of operating 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, the device of the traction hook plate does not protrude from the operating bed, and does not affect the operation of the surgeon's standing operation.

Embodiment 1

[0030] Such as figure 1 , 2 shown.

[0031] 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...

Embodiment 2

[0035] Such as image 3 , 4 , 5 shown.

[0036] 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...

Embodiment 3

[0040] Such as Figure 6 , 7 shown.

[0041] 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...

Abstract

The invention relates to an operation retractor with a built-in draw-off chain rope. The operation retractor comprises a vertical post (1) and a hook plate (2). The vertical post (1) adopts a fixed structure or a lift structure and is directly connected with an operation table or is connected with the operation table through a fixed frame (3). The operation retractor is characterized in that the hook plate (2) is connected with one end of the draw-off chain rope (13), and the other end of the draw-off chain rope (13) is extended into a hollow cavity of the vertical post (1) by a drive device (22) installed on the vertical post (1). The operation retractor has a simple structure and a small size, provides a good operation view, does not occupy the space outside the operation table, can arbitrarily move along the operation table according to demands, and is used for retracting surgical incision in any part of human body trunk.

Description

[0001] This application is a divisional application of an invention patent filed on August 9, 2010 with the application number 201010248330.4 and the title of the invention being "pull chain cord built-in surgical retractor". technical field [0002] 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 [0003] 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 fr...
