Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a medical operating headrest for an operating table. Background Art

[0002] A medical operating headrest is a surgical head support installed on an operating table for adjusting the position of a patient's head. Most medical operating headrests on the market are made of stainless steel material in order to firmly fix the patient's head. In the actual application process, since a large number of imaging devices such as three-dimensional images and X-ray images are used in existing intracranial surgeries, the medical operating headrest made of metal material does not have good ray penetration performance, which will cause artifacts in the images, thus affecting the smooth progress of the surgery.

[0003] To overcome the above defects, in the prior art, a fully transmissive medical operating headrest made of carbon fiber material is used as a medical device for fixing a patient's head when medical staff perform surgeries. It is used to fix the head when the patient lies supine, and can also be used in combination with other medical surgery situations (such as performing a head CT). However, the currently common fully transmissive medical operating headrest made of carbon fiber material cannot meet the need for lateral adjustment of the headrest, or requires medical staff to adjust by hand-tightening screws and manually drag the position of the headrest to achieve lateral adjustment; if in an unloaded state, when medical staff drag the headrest of the medical operating headrest, the friction is small and it can be dragged; if in a loaded state, due to the increase in friction, the difficulty for medical staff to drag the headrest increases, and even it cannot be adjusted due to excessive friction. The adjustment operation is cumbersome and the adjustment accuracy is low, which cannot meet the user's usage requirements. Summary of the Utility Model

[0030] Example 1

[0031] Please refer to Figures 1 to 3 , a medical operating headrest provided in the first embodiment of the present utility model is arranged on an operating bed. The medical operating headrest includes a headrest 1 for abutting against a patient's head, a fixing mechanism 2, and a support seat 3 arranged between the headrest 1 and the fixing mechanism 2. The fixing mechanism 2 includes a limiting rod 21 connected to the support seat 3 and a driving assembly 23 for driving the support seat 3 to move relative to the limiting rod 21. The driving assembly 23 includes a driving rod 231 rotatably connected to the support seat 3 and a driving member 232 for driving the driving rod 231 to rotate relative to the support seat 3. By firmly installing the medical operating headrest on the operating bed through the fixing mechanism 2, medical staff can drive the driving rod 231 to rotate relative to the support seat 3 through the driving member 232, so as to drive the support seat 3 to move along the driving rod 231 relative to the limiting rod 21, thereby driving the headrest 1 to be horizontally adjusted. At the same time, the movement direction of the support seat 3 is restricted by the limiting rod 21 to prevent the movement track of the support seat 3 from deviating under the driving action of the driving rod 231. The medical operating headrest provided by the present utility model can realize the horizontal adjustment of the headrest 1 by medical staff rotating the driving member 232, with convenient operation and high adjustment accuracy, which can meet the user's usage requirements and is beneficial to improving the user experience.

[0032] Optionally, a first through hole 31 for the limiting rod 21 to penetrate and a second through hole 32 for the driving rod 231 to penetrate are provided through the support seat 3. An external thread is provided on the outer surface of the driving rod 231, and an internal thread adapted to the external thread is provided on the inner wall of the second through hole 32. Since the external thread on the driving rod 231 is adapted to the internal thread on the inner wall of the second through hole 32, it can be realized that the driving member 232 drives the driving rod 231 to rotate relative to the support seat 3, so as to drive the support seat 3 to move along the driving rod 231 relative to the limiting rod 21, thereby driving the headrest 1 to be horizontally adjusted. At the same time, by arranging the limiting rod 21 to penetrate the first through hole 31 on the support seat 3 and the driving rod 231 to penetrate the second through hole 32 on the support seat 3, the movement direction of the support seat 3 is restricted by the limiting rod 21 to prevent the support seat 3 from rotating relative to the fixing mechanism 2 under the driving action of the driving rod 231.

[0036] Please refer also to Figures 1 to 2 In Embodiment 3 of the present utility model, a medical operating headrest is provided. The driving member 232 includes a driving seat 2321 provided at the end of the driving rod 231 and a driving handle 2322 provided on the driving seat 2321. By firmly installing the driving seat 2321 at the end of the driving rod 231 and providing a driving handle 2322 on the driving seat 2321, the medical staff rotates the driving handle 2322, driving the driving seat 2321 to rotate around the driving rod 231 as the rotation center, thereby driving the support seat 3 to move relative to the limiting rod 21 along the driving rod 231, and further realizing the lateral adjustment of the headrest 1. The operation is convenient and the adjustment accuracy is relatively high, which can meet the user's usage requirements.

[0037] Optionally, the driving handle 2322 is rotatably arranged on the driving seat 2321. An installation structure 2323 for installing the driving handle 2322 is provided on the driving seat 2321. The driving handle 2322 is firmly installed at a preset position on the driving seat 2321 through the installation structure 2323.

[0038] Optionally, the installation structure 2323 is a receiving groove formed by the surface of the driving seat 2321 recessing inward for the driving handle 2322 to be placed in. When the headrest 1 does not need to be laterally adjusted, the driving handle 2322 can be rotated and placed in the installation structure 2323 on the driving seat 2321 to store the driving handle 2322, preventing the medical staff from misoperating during the operation, which is beneficial to ensuring the safety and reliability of the medical operating headrest.

[0039] Optionally, a scale is provided on the outer surface of the driving rod 231, which is convenient for the medical staff to read the adjustment value during the adjustment process, effectively improving the adjustment accuracy of the medical operating headrest and meeting the user's usage requirements.

The fixing mechanism 2 further includes a clamping assembly 22 disposed at both ends of the limiting rod 21 and used for fixedly connecting with the operating table. The clamping assembly 22 includes a clamping frame 221 fixedly connected with the limiting rod 21, and a first clamping plate 222 and a second clamping plate 223 spaced apart on the clamping frame 221. A clamping area is formed by enclosing between the first clamping plate 222 and the second clamping plate 223. The side of the operating table is placed into the clamping area formed by enclosing between the first clamping plate 222 and the second clamping plate 223 on the clamping frame 221, so as to realize the fixed connection of the operating headrest for medical use on the operating table. Since the clamping assemblies 22 are disposed at both ends of the limiting rod 21, the connection between the operating headrest for medical use and the operating table is more stable, which is beneficial to ensuring the stability and reliability of the operating headrest for medical use.

[0042] Optionally, a protective pad 224 is disposed on the side of the first clamping plate 222 facing the clamping area. A tightening wrench 225 for driving the protective pad 224 to approach or move away from the second clamping plate 223 is disposed on the first clamping plate 222. The protective pad 224 can prevent the surface of the operating table from being scratched. The tightening wrench 225 is disposed on the first clamping plate 222. The tightening wrench 225 can adjust the distance between the second clamping plate 223 and the protective pad 224, so that the clamping assembly 22 can clamp on the operating table or loosen the operating table, facilitating the installation or removal of the operating headrest for medical use.

[0043] Example 5

[0044] Please refer to Figure 1 , and Figures 3 to 7, an operating headrest for medical use provided by Embodiment 5 of the present utility model further includes an adjusting assembly 4 disposed between the support base 3 and the headrest 1, which enables more lateral and longitudinal position adjustments of the headrest 1 to meet the usage requirements of users. The adjusting assembly 4 includes an adjusting seat 41 fixedly connected to the headrest 1, a first adjusting rod 42, a second adjusting rod 43, a first connecting shaft 44, a second connecting shaft 45, and a locking member 46. The first adjusting rod 42 and the second adjusting rod 43 are arranged at intervals. The first connecting shaft 44 is disposed at the first end of the second adjusting rod 43, and the second connecting shaft 45 is disposed at the second end of the second adjusting rod 43. The first connecting shaft 44 is fixedly connected to the first adjusting rod 42, the adjusting seat 41, and the second adjusting rod 43 in sequence. The second connecting shaft 45 is fixedly connected to the second adjusting rod 43, the support base 3, and the second adjusting rod 43 in sequence. A waist-shaped hole 33 through which the second connecting shaft 45 penetrates is provided through the support base 3. The second connecting shaft 45 can move relative to the support base 3 along the waist-shaped hole 33. The locking member 46 is used to adjust the distance between the first adjusting rod 42 and the second adjusting rod 43. Since the first adjusting rod 42 and the second adjusting rod 43 are arranged at intervals, and both the support base 3 and the adjusting seat 41 are disposed between the first adjusting rod 42 and the second adjusting rod 43, the first adjusting rod 42, the adjusting seat 41, and the second adjusting rod 43 can all rotate relative to the first connecting shaft 44 with the first connecting shaft 44 as the rotation center. The second adjusting rod 43, the support base 3, and the second adjusting rod 43 can all rotate relative to the second connecting shaft 45 with the second connecting shaft 45 as the rotation center. And since the second connecting shaft 45 penetrates through the waist-shaped hole 33 of the support base 3, that is, one end of the first adjusting rod 42 connected to the second connecting shaft 45 and one end of the second adjusting rod 43 connected to the second connecting shaft 45 can both perform reciprocating linear motion along the extending direction of the waist-shaped hole 33. Thus, when the patient's head abuts against the headrest 1, the position of the headrest 1 can be adjusted by adjusting the distance between the first adjusting rod 42 and the second adjusting rod 43 through the locking member 46. When the distance between the first adjusting rod 42 and the second adjusting rod 43 is at the maximum value, the position and angle of the headrest 1 can be adjusted until the patient's head is in a suitable position. When the adjustment is completed, the distance between the first adjusting rod 42 and the second adjusting rod 43 is adjusted to the minimum value through the locking member 46 to lock the position of the headrest 1.

[0045] Optionally, the adjusting seat 41 includes a mounting portion 411 fixedly connected to the headrest 1 and a limiting portion 412 abutted against the second adjusting rod 43. The adjusting seat 41 is fixedly connected to the headrest 1 through the mounting portion 411 and is movably abutted against the second adjusting rod 43 by means of the limiting portion 412. A first ratchet 4121 is provided on the limiting portion 412, a second ratchet 451 is provided on the second connecting shaft 45, a third ratchet 431 is provided at the first end of the second adjusting rod 43, and a fourth ratchet 432 is provided at the second end of the second adjusting rod 43. When the distance between the first adjusting rod 42 and the second adjusting rod 43 is minimized, the first ratchet 4121 and the third ratchet 431 are meshed and connected, and the second ratchet 451 and the fourth ratchet 432 are meshed and connected. At this time, the position of the headrest 1 is locked at the desired position. When it is necessary to adjust the position of the headrest 1, the distance between the first adjusting rod 42 and the second adjusting rod 43 is adjusted to the maximum value by means of the locking member 46. At this time, the first ratchet 4121 and the third ratchet 431 are disengaged from meshing, and the second ratchet 451 and the fourth ratchet 432 are disengaged from meshing. At this time, the position and angle of the headrest 1 can be adjusted until the head of the patient is in a suitable position. When the adjustment is completed, the distance between the first adjusting rod 42 and the second adjusting rod 43 is adjusted to the minimum value by means of the locking member 46 to lock the position of the headrest 1; the distance between the first adjusting rod 42 and the second adjusting rod 43 is adjusted by switching the state of the locking member 46, so as to change the tightness state between the adjusting seat 41 and the second adjusting rod 43 and the tightness state between the second connecting shaft 45 and the second adjusting rod 43. Then, the medical staff manually adjusts the positions of the various components to adjust the position of the headrest 1. The operation is convenient, it is applicable to more usage scenarios, and it meets the usage requirements of users.
