Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and particularly relates to an integrated scalp retractor structure. Background Art

[0002] Scalp retractors are often used in craniotomy to pull the scalp and prevent the scalp from re-covering the craniotomy site. Currently, surgical scalp retractors are commonly used. Their main body consists of two parts, including a retractor and a traction rope, which are clamped and fixed with towel clamps. The scalp retractor takes a long time to assemble during use, and the use of rubber bands may cause surgical safety hazards if they fall off. It is not easy to select the number of retractors according to the size of the surgical incision during installation. The fixed installation position of the scalp retractor can easily block the surgical field of view, affecting the use effect. Therefore, a new integrated scalp retractor structure is designed to change the above technical defects. Utility Model Content

[0020] This specific embodiment is an integrated scalp retractor structure, and its structural diagram is as follows: Figure 1-Figure 5 As shown, the scalp retractor structure includes a slide rail 14, a card slot 3 is provided on the outer surface of the slide rail 14, and a slide seat 6 is slidably installed inside the slide rail 14, a cavity 22 is provided inside the slide seat 6, a slide hole 24 and a plug hole 25 are provided on the outer surface of the slide seat 6, and the slide hole 24 and the plug hole 25 are both connected to the cavity 22, and plug pieces 9 are slidably installed inside the two slide holes 24, and the two plug pieces 9 are fixedly connected to the plug block 20 on the side away from each other, and the plug block 20 is slidably installed inside the plug hole 25 and the card slot 3, and the side of the two plug pieces 9 close to each other is fixedly connected by a compression spring 21, and a ball shell 4 is installed on the end of the slide seat 6 away from the slide rail 14, and the ball shell 4 is rotatably installed inside There is a rotating ball 2, and the outer surface of the rotating ball 2 is fixedly connected to the scalp retractor 1, the outer surface of the ball shell 4 is penetrated by the air pressure cylinder 5, and the inside of the air pressure cylinder 5 is installed with a sealing ring 16, the top of the air pressure cylinder 5 is provided with a threaded hole 17, and the internal thread of the threaded hole 17 is connected to the screw rod 18, and the bottom end of the screw rod 18 is rotatably installed with a piston 19, the outer surface of the slide rail 14 is installed with a hanging ring 15, and the inside of the hanging ring 15 is installed with a tension spring 10, and the end of the tension spring 10 away from the hanging ring 15 is installed with two metal chains 11, the outside of the metal chain 11 is provided with a cloth towel clamp 13, and the cloth towel clamp 13 and the metal chain 11 are installed by an O-ring 12, and the material of the slide rail 14 is medical stainless steel.

[0021] The ends of the two inserts 9 facing away from each other are each fitted with a U-shaped pressing piece 8. This arrangement facilitates the medical professional's pressing of the inserts 9 and prevents slipping. The end of the screw rod 18 facing away from the piston 19 is fixedly connected to a handle 7, which is covered with a non-slip sleeve. This arrangement facilitates the rotation of the screw rod 18.

[0022] In addition, the ends of the two plug-in blocks 20 that are away from each other are both provided with a slot 23, and the ends of the two plug-in blocks 20 that are away from each other are both tapered. The provision of the slot 23 facilitates the insertion of the plug-in blocks 20 into the card slot 3 for installation.

[0023] Working principle: When using the scalp retractor structure of the present technical solution, the medical staff presses the insert 9 to make the insert block 20 enter the inside of the socket 25. At this time, the compression spring 21 is in a compressed state. The slide 6 is inserted into the inside of the slide rail 14. Then, the insert 9 is released and the elastic force of the compression spring 21 pushes the insert 9 with the insert block 20 to slide out of the inside of the socket 25, so that the insert block 20 is inserted into the slot 3 on the slide rail 14 and fixed. The slide 6 is installed with the ball shell 4, the rotating bead 2 and the scalp retractor 1. The number of scalp retractors 1 to be installed can be selected according to the size of the patient's surgical incision, so that multiple scalp retractors 1 can open the patient's surgical incision in all directions, which is convenient for the doctor to perform the surgical operation. When the rotating bead 2 rotates inside the ball shell 4, the scalp retractor 1 is opened. The hook 1 is rotated to adjust the angle and position, and then the screw rod 18 is twisted to rotate and move in the threaded hole 17. The movement of the screw rod 18 brings the piston 19 to the side away from the rotating ball 2. The movement of the piston 19 generates suction in the air pressure cylinder 5 to adsorb the rotating ball 2, thereby fixing the rotating ball 2 and the scalp retractor 1. The rotation adjustment angle and position of the scalp retractor 1 can effectively prevent the scalp retractor from being fixed in the installation position and easily blocking the surgical field of view, thereby ensuring the doctor's field of view during surgery. The tension spring 10, metal chain 11, O-ring 12 and cloth towel clamp 13 are matched with the scalp retractor 1, so that the scalp retractor structure is installed in one piece, thereby preventing the scalp retractor from being assembled for a long time and affecting the use effect. The installation connection is strong and stable, thereby avoiding the safety hazards of surgery caused by the traditional use of rubber bands falling off.
