Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a surgical retractor traction bracket. Background Art

[0002] In surgical operations, after the skin and muscles are cut open, surgical retractors are used to pull the skin and muscles to expose the surgical field. For example, during neck lymph node dissection, retractors are needed to pull the sternocleidomastoid muscle. Especially in laparoscopic surgery, the laparoscopic-assisted cavity creation system is mostly imperfect. Due to the small skin incision, the width of the retractor is limited, making the space formed by the traction small and the cavity creation limited. Moreover, if the traction is done manually, the strength is difficult to control and unstable, which affects the progress of the operation.

[0003] Although the existing surgical retractor bracket solves the problem of time-consuming and labor-intensive manual pulling to a certain extent, its structure is often complicated, inconvenient to operate, and difficult to adjust. Summary of the invention

[0004] The object of the present invention is to provide a surgical retractor traction bracket, which can fix the surgical retractor, and can conveniently adjust the position and angle of the surgical retractor, and has a simple structure.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A surgical retractor traction bracket comprises a support rod, a first horizontal adjustment tube, a second horizontal adjustment tube and a vertical adjustment device, wherein the first horizontal adjustment tube and the second horizontal adjustment tube are both L-shaped, the outer end of the vertical tube of the first horizontal adjustment tube is rotatably connected to the top of the support rod, and the outer end of the vertical tube of the second horizontal adjustment tube is rotatably connected to the outer end of the horizontal tube of the first horizontal adjustment tube;

[0007] The vertical adjustment device comprises a vertical adjustment tube and a rack. A ball-and-socket joint is provided at the top of the adjustment tube. The side of the ball-and-socket joint is fixed to the outer end of the horizontal tube of the second horizontal adjustment tube. A locking tongue is fixed to the side wall of the adjustment tube through a torsion spring. The rack is inserted into the adjustment tube from the bottom of the adjustment tube. The locking tongue extends into the adjustment tube to form a locking fit with the rack.

[0008] A retractor fixing fixture for fixing the surgical retractor is provided at the bottom of the rack.

[0009] Furthermore, a first locking pin is provided on the side wall of the vertical tube of the first horizontal adjustment tube, a first locking tooth is provided on the top of the support rod, the outer end of the vertical tube of the first horizontal adjustment tube is sleeved on the outer periphery of the first locking tooth, and the first locking pin cooperates with the first locking tooth.

[0010] Furthermore, a second locking pin is provided on the side wall of the vertical tube of the second horizontal adjustment tube, a vertical locking tooth column is provided on the outer end of the horizontal tube of the first horizontal adjustment tube, and the outer end of the vertical tube of the second horizontal adjustment tube is sleeved on the outer periphery of the locking tooth column, and the second locking pin cooperates with the locking tooth column.

[0011] Furthermore, a ball and socket locking rod is vertically provided on the top of the ball and socket joint, and the ball and socket locking rod cooperates with the top thread of the ball and socket joint. The bottom end of the ball and socket locking rod extends into the ball and socket joint and is connected with a locking piece, which cooperates with the joint ball.

[0012] Furthermore, the locking piece is a rectangular block with a recess at the bottom, and the recess of the rectangular block cooperates with the joint ball.

[0013] The beneficial effects of the present invention are that the surgical retractor is fixed on the retractor fixing fixture, and can be rotated 360° through the first horizontal adjustment tube and the second horizontal adjustment tube to adapt to the operating range of the operation; the height of the surgical retractor can be adjusted through the cooperation of the rack and the locking tongue; the surgical retractor can also be adjusted in any direction of 360° through the ball and socket joint, and when adjusted to the required position, the position of the surgical retractor can be fixed by operating the ball and socket locking rod to lock the joint ball with the locking piece; the device has a simple structure and is easy to use.
