Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of head fixing pillows, in particular to a head fixing pillow for lung puncture biopsy under CT guidance. Background Art
[0002] When performing a CT-guided lung puncture biopsy, it is very important to ensure that the patient's head is fixed. Fixing the head helps maintain the patient's safety and accuracy, and can provide better imaging results. During a CT-guided lung puncture biopsy, the doctor will place the patient's head on a fixed pillow as needed and use an appropriate fixation device to fix the head, which can ensure that the patient does not move the head during the puncture, thereby reducing errors and risks.
[0003] In the process of implementing this application, the inventor found that there are at least the following problems in this technology:
[0004] (1) Each patient's head shape and size are different, and the head fixation pillow and restraint belt are usually standardized in design and cannot fully meet the needs of all patients, resulting in poor fixation effect. The head still has slight movement or instability, affecting the accuracy of puncture.
[0005] (2) Since the fixed pillow and the restraint belt cannot rebound automatically, the doctor needs to manually adjust the fixed position and tightness when using them, which may increase the difficulty and time of the operation. During lung puncture or other medical operations, the patient needs to keep the head fixed for a long time, which may cause discomfort, such as head pain and pressure. Utility Model Content
[0006] In view of the deficiencies in the prior art, the utility model provides a head fixation pillow for CT-guided lung puncture biopsy, which has the advantages of simple and quick fixation of the restraint belt and the ability of the restraint belt to automatically rebound and automatically adapt to different head circumferences, thereby solving the problems of complex fixation of the restraint belt and the inability to automatically rebound.
[0007] The utility model provides the following technical solution: a head fixing pillow for lung puncture biopsy under CT guidance, comprising a bottom pillow, a buckle groove is provided inside the bottom pillow, one end of a spring one is fixedly connected to the surface of the buckle groove, a clamping block two is fixedly connected to the other end of the spring one, a circular groove is provided inside the clamping block two, and a rotating shaft is rotatably sleeved inside the circular groove, two ends of the rotating shaft are fixedly connected to the surface of the buckle groove, a limiting block one is fixedly connected to the top of the buckle groove, a switch block is provided at the lower end of the limiting block one, the bottom end of the switch block is attached to the upper end of the clamping block two, the surface of the buckle groove is fixedly connected to one end of a spring two, the other end of the spring two is fixedly connected to a spring pressure block, a clamping block one is provided at the top of the spring pressure block, a clamping groove is provided inside the clamping block one, and a clamping block two is buckled inside the clamping groove.
[0008] Preferably, a spring bin is provided inside the bottom pillow, a clamping column is fixedly connected to the surface of the spring bin, a clamping block is clamped inside the clamping column, a spring spring is fixedly connected to the top of the clamping block, and a restraining belt is fixedly connected to the outer end of the spring spring.
[0009] Preferably, a restraining belt is fixedly connected to the top of the first clamping block, and a limiting block 2 is fixedly connected to the outer wall of the restraining belt.
[0010] Preferably, a protective ring is fixedly connected to the top of the bottom pillow, a cavity is formed at the bottom end of the protective ring, and air holes are formed on the sides of the cavity.
[0011] Preferably, two sets of arm slots are provided inside the bottom pillow.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. This head fixing pillow for lung puncture biopsy under CT guidance is made by inserting the card block 1 fixedly connected to the top of the restraint belt into the buckle groove, and the bottom end of the card block 1 pushes the top end of the card block 2 to make it rotate around the rotating shaft. When the slot inside the card block 1 slides to a certain height, the spring 1 pushes the card block 2 to rebound and is locked into the slot to complete the connection. When the operation is completed, the staff presses the switch block to make it slide inside the buckle groove, pushing the lower end card block 2 to rotate. When the raised end of the card block 2 is higher than the surface of the card block 1, the elastic potential energy of the bottom spring 2 pushes the spring block to move to the upper end, pushing the card block 1 to the outside of the buckle groove to cancel the connection. When performing lung puncture biopsy, the quick and convenient switch can help doctors or nurses adjust and release the fixed pillow and restraint belt more quickly, thereby saving operation time. By quickly tightening and loosening the fixing belt, the pressure on the head can be reduced and better comfort can be provided.
[0014] 2. This type of head fixation pillow for lung puncture biopsy under CT guidance drives the restraint belt to be pulled out from the inside of the clockwork bin by pulling the second limit block. The outer end of the clockwork spring is pulled and contracts inward with the clamping column as the center. The internal clamping block is clamped in the middle of the clamping column. At the end of the operation, when the restraint belt is unfastened, it is affected by the elastic potential energy of the clockwork spring and automatically curls toward the inside of the clockwork bin to complete the automatic rewinding. The automatic retraction function can reduce the time and labor required for doctors or nurses to adjust and release the fixed pillow and restraint belt, so that doctors can perform subsequent operations faster and improve work efficiency.

The bottom end of the clamping block 14 pushes the top of the clamping block 2 16 to make it rotate with the rotating shaft 15 as the center. When When the slot inside the card block 14 slides to a certain height, the spring 10 pushes the card block 2 16 to rebound and snap into the slot to complete the snap connection. When the operation is completed, the staff presses the switch block 17 to make it slide inside the snap slot 11, pushing the lower end card block 2 16 to rotate. When the raised end of the card block 2 16 is higher than the surface of the card block 14, the elastic potential energy of the bottom spring 2 12 pushes the spring block 13 to move toward the upper end, pushing the card block 14 to cancel the snap connection to the outside of the snap slot 11. At the same time, it is affected by the elastic potential energy of the clockwork spring 8 and automatically curls toward the inside of the clockwork bin 9 to complete the automatic winding.
