A surgical retractor quick fixing device

Abstract

A quick-fixation device for a surgical retractor is characterized by comprising a column (1), an adjusting handle (2), and an end clamp (3). The lower end of the column (1) is fixed with the end clamp (3), which abuts against the bottom edge of the crossbeam of the operating table. The adjusting handle (2) has a square hole through which the column (1) passes, allowing the adjusting handle (2) to slide within the square hole. The lower end of the adjusting handle (2) is connected to an upper clamp (9), which abuts against the upper edge of the crossbeam of the operating table, thus fixing the column to the crossbeam of the operating table together with the end clamp (3). This invention employs a friction plate combination structure, which allows for convenient and flexible clamping and release of the end clamp, meeting surgical requirements. It has a simple structure, is easy to operate, and is stable and reliable.

Description

Technical Field

[0001] The invention relates to the field of medical instruments, and in particular to a quick fixing device for a surgical retractor. Background Art

[0002] Surgical retractors are generally used in open surgical operations to retract and fix the incision and maintain the surgical field. When in use, they need to be fixed on the horizontal bar on the side of the operating table. The commonly used fixing device currently uses a threaded clamp to fix it. The operator needs to manually rotate it several times to clamp it and then rotate it in the opposite direction to release it. The operation is relatively time-consuming and labor-intensive. Therefore, an innovative design of a fixing device that can be clamped and released quickly will save time and effort. Summary of the invention

[0003] The purpose of the present invention is to design a fast clamping and fast releasing fixing device to address the deficiencies of the existing surgical retractor fixing devices.

[0004] The technical solution of the present invention is:

[0005] A surgical retractor quick fixing device is characterized in that it includes a column 1, an adjustment handle 2, and an end clamp 3. The lower end of the column 1 is fixed with the end clamp 3, and the end clamp 3 is against the lower bottom edge of the crossbeam of the operating bed; there is a square hole in the adjustment handle 2, the column 1 passes through the square hole, and the adjustment handle 2 can slide in the square hole of the column 1; the lower end of the adjustment handle 2 is connected to an upper clamp 9, and the upper clamp 9 can be against the upper edge of the crossbeam of the operating bed, thereby fixing the column on the crossbeam of the operating bed together with the end clamp 3.

[0006] The adjusting handle 2 comprises a handle base 4, a trigger 5, an upper friction plate 6, a lower friction plate 13 spring 7, and a release button 8. The handle base 4 is composed of an adjusting handle 12 and an upper chuck 9. The adjusting handle 12 and the upper chuck 9 are integrally connected by a connecting rod 11. The adjusting handle 12 and the upper chuck 9 are provided with square holes for the column 1 to pass through. The trigger 5 is connected to the adjusting handle 12 by a cylindrical pin. The trigger 5 can rotate around the cylindrical pin, and one end of the trigger 5 contacts the lower friction plate 13. The other end is a manual operation end. The lower friction plate 13 is mounted on the column 1 and abuts against one end of the spring 7 which is also mounted on the column 1. The other end of the spring 7 abuts against the lower platform 14 of the adjusting handle 12. The upper friction plate 6 is also mounted on the column 1 and abuts against the lower end of the upper spring 15. The upper end of the upper spring 15 abuts against the upper platform 16 of the adjusting handle 12. One end of the upper friction plate 6 extends and contacts with the lower end of the release button 8. The release button 8 is mounted and limited on the adjusting handle 12.

[0007] A clamping groove 10 is provided on the end of the upper clamping head 9 that contacts the crossbeam of the operating table.

[0008] Hold the adjustment handle and pull the trigger back and forth. The friction plate will drive the column to move in one direction. The end clamp at one end of the column and the upper clamp of the handle base will move towards each other. The relative position will get closer and closer until the horizontal bar on the side of the operating table is clamped. When releasing, press the release button with your thumb, and the clamp will immediately loosen and disengage.

[0009] Beneficial effects of the present invention:

[0010] The present invention adopts a hand-held fixing device, which can conveniently and flexibly clamp and fix and release the surgical retractor quickly, saving time and labor.

[0011] The invention has a simple structure and is stable and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] A surgical retractor quick fixing device comprises a column 1, an adjustment handle 2, and an end clamp 3. Figure 1 As shown, the lower end of the column 1 is fixed with an end clamp 3, and the end clamp 3 is against the bottom edge of the crossbeam of the operating bed; there is a square hole in the adjustment handle 2, the column 1 passes through the square hole, and the adjustment handle 2 can slide in the square hole of the column 1; the lower end of the adjustment handle 2 is connected to an upper clamp 9, and a clamping groove 10 is provided on the end of the upper clamp 9 that contacts the crossbeam of the operating bed, as shown in FIG. Figure 3 As shown. The upper clamp 9 can abut against the upper side of the operating table cross beam 17, thereby fixing the column on the operating table cross beam together with the end clamp 3. The adjustment handle 2 includes a handle base 4, a trigger 5, an upper friction plate 6, a lower friction plate 13 spring 7, and a release button 8. The handle base 4 is composed of an adjustment handle 12 and an upper clamp 9. Figure 2The adjusting handle 12 and the upper chuck 9 are integrally connected through a connecting rod 11. The adjusting handle 12 and the upper chuck 9 are both provided with square holes for the column 1 to pass through. The trigger 5 is connected to the adjusting handle 12 through a cylindrical pin. The trigger 5 can rotate around the cylindrical pin. One end of the trigger 5 contacts the lower friction plate 13, and the other end is a manual operation end. The lower friction plate 13 is sleeved on the column 1 and abuts against one end of the spring 7 which is also sleeved on the column 1. The other end of the spring 7 abuts against the lower platform 14 of the adjusting handle 12. The upper friction plate 6 is also sleeved on the column 1 and abuts against the lower end of the upper spring 15. The upper end of the upper spring 15 abuts against the upper platform 16 of the adjusting handle 12. One end of the upper friction plate 6 extends and contacts the lower end of the release button 8. The release button 8 is sleeved and limited on the adjusting handle 12.

[0017] During operation, one hand holds the column 1 and presses one end of the end clamp 3 at the bottom of the column 4 against the lower bottom edge of the horizontal bar of the operating bed. The horizontal bar on the side of the operating bed is usually a metal strip with a rectangular cross-section. The hand holds the handle assembly 4 and pulls the trigger 5. One end of the trigger 5 will push the lower friction plate 13, and the lower friction plate 13 will drive the column 1 to move in one direction. The other upper friction plate 6 clamps the column 1 and prevents it from retreating. After the trigger is reset under the action of the lower spring 7, the trigger is pulled again to move the column a distance again. In this cycle, the distance between the end clamp 3 of the column and the upper clamp 9 on the handle base 4 will become closer and closer until the horizontal bar is clamped.

[0018] There are three friction plates in total, the two lower plates (lower friction plates 13) are used for triggering the column, and the upper plate (upper friction plate 6) is used for locking and releasing. That is, when the thumb presses the release button 8, it will trigger a friction plate to rotate, causing it to lose friction with the column, so that the column can be pulled by hand and moved in another direction, thereby increasing the distance between the two clamps (end clamp 3 and upper clamp 9) and releasing the horizontal bar.

[0019] The parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art.
