Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments for plastic surgery, and more particularly to a fixing fixture for plastic surgery. Background Art

[0002] Plastic surgery, a branch of surgery also known as reconstructive or plastic surgery, primarily treats injuries and diseases of the skin, muscles, and bones, as well as congenital and acquired defects and deformities of tissues and organs. Treatment encompasses both repair and reconstruction. While surgical transplantation of autologous tissues is the primary approach, allogeneic or xenogeneic tissues or tissue substitutes can also be used to repair tissue defects or deformities caused by various reasons, aiming to improve or restore physiological function and appearance.

[0003] When performing plastic surgery on a patient, in order to facilitate surgery on the patient's head, a clamp will be used to limit and clamp the patient's head so that the surgery can proceed normally; however, most of the existing clamps for the head use a splint to clamp the patient's head in a single manner, such as a clamp for plastic surgery with application number: CN202120069005.5, which includes a bearing seat and an opening arranged in the middle of the bearing seat, a head clamping assembly is arranged at the bottom of the opening, and an angle adjustment assembly is arranged on one side surface of the bearing seat; the head clamping assembly includes a head support platform, the head support platform is arranged at the bottom of the opening, a groove is arranged on the top of the head support platform, a bidirectional ball screw is rotatably arranged in the groove, a first nut and a second nut are symmetrically arranged on both sides of the bidirectional ball screw, a first splint is arranged at one end of the first nut, and a second splint is arranged at one end of the second nut, one end of the bidirectional ball screw is connected to the drive shaft of the first motor, and the first motor is arranged on one side surface of the head support platform; it is connected through a double The rotation of the ball screw causes the first nut and the second nut to drive the first clamping plate and the second clamping plate respectively, and the patient's head is clamped and fixed by the first clamping plate and the second clamping plate; the horizontal screw is rotated, and the rack is driven to move by the third nut, and the transmission of the rack and the gear drives the rotating shaft to rotate, and the rotating shaft drives the head support platform to rotate through the connecting ear plate, and then the angle of the patient is fine-tuned; but since it is driven by a motor during adjustment, and the angle to be adjusted during surgery needs to be adjusted according to the field of view required by the doctor, the motor is relatively inconvenient to control. At the same time, it drives the two sets of clamping plates to clamp the patient's head through the motor-controlled screw. The rigid clamping will cause discomfort to the patient's head. In addition, its rotation angle is limited and it cannot be adjusted at a large angle. Finally, its head clamping component is located in the opening on the support seat, so that its end is blocked by the inner wall of the support seat, which makes it impossible to perform surgery on the patient's head position.

[0004] In view of the above situation, the present invention designs a fixing fixture for plastic surgery to solve the above technical problems. Summary of the Invention

[0007] Preferably, connecting blocks are respectively provided at the four corners of the support block, and the connecting blocks form a group of two. The two connecting blocks are connected by a fixing strap, and the tightness of the fixation of the patient's head can be adjusted by changing the length of the fixing strap.

[0014] Beneficial effects of the present invention: When the support block slides to the left, the moving block can be pulled upward to disengage the locking block, thereby canceling the position restriction of the locking block on the locking block, so that the support block can move in both directions in the arc groove, thereby eliminating the need for the doctor to maintain the same posture for a long time during surgery, and making the operation more convenient.

[0015] 2. The present invention provides a fixing clamp for plastic surgery. The device cooperates with the support block through the support structure. When the patient's head is fixed on the support block, the patient's head can be stabilized by the fixing strap to prevent the patient's head from rotating with the rotation of the support block during the operation. At the same time, the patient's neck fits the neck pillow. When the doctor adjusts the surgical field of view, the torque spring combined with the ball hinge can ensure that the neck pillow always fits the patient's neck, avoiding the patient's neck being suspended in the air during long-term surgery, causing discomfort to the patient.

[0025] Specifically, the rotational connection between the hinge seat 42 and the support rod 43 can be achieved through a torque spring.

[0026] Working principle and working process: before the operation begins, the medical staff first fixes the device body 1 to the side of the operating table, first clamps the fixing groove 22 opened on the fixing block 21 to the side of the operating table, and then fixes the device body 1 through the rotating block 23. The rotating block 23 and the fixing block 21 are connected by a threaded connection, so that the device body 1 can be firmly set on the side of the operating table to prevent the device body 1 from falling. After the device body 1 and the operating table are fixed, the mounting rod 2 is adjusted in different mounting holes 112 according to the patient's height and the needs of the operation, thereby adjusting the operating height to facilitate the doctor to perform the operation on the patient; During the operation, the patient lies flat on the operating table and places his head on the support block 12. Since the arc-shaped groove of the support block 12 is provided with soft material, it can ensure that the patient remains comfortable during the operation. Then, in order to prevent the patient's head from shaking during the operation, the patient's head is fixed by the fixing strap 125 provided on the connecting block 124. The fixing strap 125 is a retractable structure, so that it can be adaptively adjusted according to the different heads and tails of different patients. At this time, the patient's neck is placed on the cervical pillow 44. Through the cooperation of the ball joint 41, the hinge seat 42 and the support rod 43, the patient's neck can always fit on the cervical pillow 44 during the operation, avoiding the neck being suspended for a long time when the patient's head moves, resulting in discomfort in the patient's neck after the operation is completed. The rotational connection between the hinge seat 42 and the support rod 43 can be through the method of a torque spring. Through such a connection method, the cervical pillow 44 can provide a supporting force to the patient's neck to avoid the patient's neck being suspended. When the doctor's surgical field is obstructed, if the doctor wants to operate on the patient's right side, the doctor pushes the support block 12 to the right. At this time, the moving block 31 connected to the lower part of the support block 12 moves synchronously with the support block 12, and the locking claw 32 rotated at one end of the moving block 31 can slide along the locking block 114 opened on the arc groove 113. When the support block 12 slides, the locking claw 32 squeezes the connecting spring 33, and the connecting spring 33 can push the locking claw 32 to reset. If the doctor operates on the patient's left side, the doctor needs to move the control rod 311 upward, and the control rod 311 drives the locking claw 32 to disengage the locking block 114. At this time, the doctor pushes the support block 12 to the left again. When the position adjustment is completed, it is only necessary to push the control rod 311 downward, and the control rod 311 makes the moving block 31 fit the load-bearing plate 34. At the same time, the locking claw 32 cooperates with the locking block 114, thereby completing the adjustment of the patient's head position and fixing the surgical position of the patient's head.
