Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of surgical support, in particular to a spine surgical support. BACKGROUND

[0002] The spine is the body's support, located in the middle of the back, the upper end of the skull, the lower end of the tailbone. The spine is divided into neck, chest, waist, sacrum and tail, the upper part is long and can move, like a support, hanging the chest wall and abdominal wall; the lower part is short and relatively fixed. The weight of the body and the shock received is transmitted to the lower limbs, the spine is composed of vertebrae and intervertebral discs, and is a relatively soft and movable structure. With the movement load of the body, the shape of the spine can change greatly. The movement of the spine depends on the integrity of the intervertebral disc, the harmony between the related articular processes of the vertebrae, and the length of the spine, 3 / 4 of which is composed of vertebral bodies, and 1 / 4 of which is composed of intervertebral discs.

[0003] Now the traditional spine surgical support still has certain deficiencies in patient body heat preservation. When the patient needs to be naked from the waist up when the patient is operated in the cold season, and the spine correction operation time is relatively long, some patients with relatively weak bodies are prone to illness due to wind and cold, which has a certain impact on the postoperative rehabilitation, and the traditional support bearing plate is relatively hard. Because the patient is in a prone position during the operation, the abdomen and chest will be subjected to a lot of pressure, greatly increasing the patient's discomfort.

[0004] As disclosed in a spine surgical support in Chinese patent publication No. CN115089424B, the spine surgical support is provided with a first water bag, and by setting the first water bag and the second water bag, when the second water bag is pressed by the patient's body, the second water bag will deform according to the patient's body shape, wrapping the patient, reducing the patient's discomfort when lying prone, and the liquid in the second water bag will enter the first water bag through the connecting hose, making the first water bag expand, reducing the gap between the positioning baffle and the body, and repositioning the patient's body. The wear-resistant protective layer in the protective connecting sleeve is of polyester material, increasing the wear resistance of the protective connecting sleeve, and the inner side of the wear-resistant protective layer is provided with a sponge connecting layer and a metal woven layer, the sponge connecting layer is located on both sides of the metal woven layer, avoiding the metal wire on the metal woven layer from being pulled out of the protective connecting sleeve, and the sponge connecting layer is provided with a plurality of connecting through holes, increasing the air permeability of the protective connecting sleeve. The metal woven layer is used to prevent sharp foreign objects from penetrating the protective connecting sleeve and piercing the second water bag. Finally, the heating rod in the second water bag is used, the heating rod is provided with two and is arranged in a curved and folded structure, to increase the surface area of the heating rod, reduce the heating time of the second water bag, keep the second water bag at a suitable temperature for the human body, reduce the loss of body temperature of the patient in the cold season, and improve the comfort.

[0005] First, the above surgical support reduces the discomfort of the abdomen and chest of the patient when prone, and the liquid in the second water bag enters the first water bag through the docking hose, completing the repositioning of the patient's body, but this way is more suitable for patients with lighter weight, and for patients with heavier weight, the water in the water bag is affected by pressure, and gathers on both sides of the water bag, and the middle part of the patient still exists in the prone position. The abdomen and chest of the patient still have discomfort, and the support lacks a limiting mechanism for the patient's legs during the operation, so when the patient's legs move during the operation, the legs rotate relative to the spine, and this rotation is transmitted to the sacroiliac joint in the pelvis. At this time, the pelvis produces a compensatory response, thus affecting the normal progress of the spinal surgery at this time. SUMMARY

The adjusting unit comprises a chest pad seat 201 and an abdomen pad seat 202 arranged at the middle part of the support base 100, and the two sides of the chest pad seat 201 and the abdomen pad seat 202 are provided with sliding clamping blocks 203, and the two sliding clamping blocks 203 are welded at the edge wall of the mounting port of the support base 100. In the actual surgery process, there are generally differences in the proportion of the patient's body, so that the chest pad seat 201 and the abdomen pad seat 202 can be finally slid to perfectly adapt to the chest and abdomen of the patient, and therefore the chest pad seat 201 and the abdomen pad seat 202 slide in the mounting port of the support base 100 through the sliding clamping blocks 203. The one side of the chest pad seat 201 and the abdomen pad seat 202 is provided with a partition plate 204, and the two partition plates 204 are welded at the inner wall of the mounting port of the support base 100. The two partition plates 204 are fixedly installed with adjusting seats 205, and the position of the chest of the human body is not necessarily linearly connected with the position of the abdomen, so that the position of the chest pad seat 201 and the abdomen pad seat 202 can only be adjusted separately and cannot be adjusted as a whole. Finally, the present application separately provides two adjusting seats 205 corresponding to the chest pad seat 201 and the abdomen pad seat 202, and the interior of the two adjusting seats 205 is provided with sliding grooves, and the sliding grooves are symmetrically provided with adjusting blocks 206.

The adjusting blocks 206 are screw-connected with the corresponding threaded rods 211. The two ends of the threaded rod 211 are bidirectional threads. Finally, the application is rotated by rotating the corresponding threaded rod 211. Due to the threaded connection, the adjacent adjusting blocks 206 simultaneously move in the opposite direction. In this process, the length of the articulated push rod 208 is constant. In the process of rotating the articulated push rod 208, the adjusting block 206 is pulled. Therefore, the articulated push rod 208 makes the chest pad seat 201 and the abdominal pad seat 202 slide on the sliding clamping block 203 through the fixed shaft 209 and the fixed block 210, so as to change the support position of the chest and abdomen of the patient, so that the support frame is adapted to and compatible with different patients and different surgical needs.

The MR fluid layer 2004 at the bottom is similar to a water bag in a normal state, providing a wrapping and buffering feeling when the patient lies down. When the patient is heavier, the MR fluid in the MR fluid layer 2004 changes from a low-viscosity Newtonian fluid to a solid-like or solid molecular property under the action of an external magnetic field, providing sufficient support as required, avoiding the patient's chest or abdomen from sinking and losing support, causing the lumbar joint and other positions of the spine to protrude. The inner walls of the chest pad 201 and the abdominal pad 202 are provided with heating compartments 2005. The heating compartments 2005 are provided with metal rods 2006. In order to generate a magnetic field required for the MR fluid to change its properties during heating, an electromagnetic heating method is used to generate heat in the metal rods 2006. The metal rods 2006 are wound with electromagnetic coils 2007. In order to ensure the circulation of the air holes 2002 and hot air, a plurality of circulation holes are provided on the side walls of the heating compartments 2005. The material of the side walls of the heating compartments 2005 is selected to be lightweight aluminum plate. The lightweight aluminum plate has good conductivity and ductility, so it is selected as the conductor and insulator carrier in this application. Further, the MR fluid is prevented from expanding too much to cause the chest pad 201 or the abdominal pad 202 to deform as a whole.
