Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a thoracoscopic positioning fixation device. Background Technology

[0002] Thoracoscopic surgery is a minimally invasive surgical technique that involves inserting a thoracoscope and surgical instruments through a small incision in the chest wall to diagnose and treat intrathoracic diseases under high-definition image guidance. The 90° lateral decubitus position is the most commonly used position in thoracoscopic surgery, as it provides ample exposure and facilitates the surgeon's operation.

[0003] In clinical practice, in order to enable patients to maintain a 90° lateral decubitus position after general anesthesia, the patient is usually positioned before anesthesia, and pillows are placed on the patient's chest and back to fix the patient's position and enhance the stability of the position.

[0004] However, the above-mentioned methods of fixing the body position cannot fix the pillow, which is prone to slipping off during the operation. This makes the patient's side-lying position unstable, easy to shift and deform, and medical staff need to adjust the patient's position frequently, which is time-consuming and laborious, and increases the workload of medical staff. Utility Model Content

[0005] This invention provides a thoracoscopic positioning fixation device, which aims to effectively fix the patient's position and prevent changes in position.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A thoracoscopic positioning device includes a base plate and a positioning pillow. The upper surface of the base plate is provided with a T-shaped sliding groove, and both ends of the T-shaped sliding groove are provided with sliding blocks that can extend out of the upper surface of the base plate. The lower end of the positioning pillow is provided with a fixing post. The sliding block is provided with a fixing groove that matches the cross-sectional shape of the fixing post. The fixing post is detachably inserted into the fixing groove and connected to the sliding block. The two ends of the T-shaped sliding groove are also threaded with adjusting bolts, one end of which is inserted into the T-shaped sliding groove and abuts against the sliding block.

[0008] As a further improvement to the above technical solution:

[0009] The body positioning pillow includes a chest pad and a back pad. The fixing posts on the lower end surfaces of the chest pad and the back pad are both located in the middle and are respectively connected to the sliding blocks at both ends of the T-shaped sliding groove. The length of the chest pad is less than the length of the back pad.

[0010] Compared with the prior art, the present invention achieves at least the following beneficial effects: The thoracoscopic positioning fixation device of the present invention can flexibly adjust the distance between the two positioning fixation pillows by moving the sliding block in the T-shaped groove to adapt to different patient body shapes. Tightening the bolt to abut against the sliding block can lock the position of the sliding block. At the same time, the positioning fixation pillow is detachably inserted into the fixing groove and connected to the sliding block through the fixing column, which enhances the fixation stability and avoids displacement during the operation.

[0018] The present application will now be described in detail with reference to exemplary embodiments shown in the accompanying drawings. However, it should be understood that the present application may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided herein to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0019] In the description of this application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limiting the scope of protection of this application.

[0020] To address the shortcomings of existing technologies, such as unstable body positioning and susceptibility to displacement and deformation, the inventors, after careful analysis, discovered that the main reason for these problems in current body positioning methods is that the pillow is not fixed relative to the bed. Based on this analysis, the inventors have made structural improvements to the body positioning device.

[0021] like Figures 1-5 As shown, a thoracoscopic positioning fixation device of the present invention includes a base plate 1, a positioning fixation pillow 2, and a knee joint soft pillow 3.

[0022] The upper surface of the base plate 1 has a T-shaped sliding groove 11, and both ends of the T-shaped sliding groove 11 have sliding blocks 12 that can extend out of the upper end of the base plate 1. The lower surface of the positioning pillow 2 has a fixing post 21, and the sliding block 12 has a fixing groove 13 that matches the cross-sectional shape of the fixing post 21. The fixing post 21 is detachably inserted into the fixing groove 13 and connected to the sliding block 12. The two ends of the T-shaped sliding groove 11 are also threaded with adjusting bolts 14, one end of which is inserted into the T-shaped sliding groove 11 and abuts against the sliding block 12. The upper surface of the base plate 1 and the outer surface of the positioning pillow 2 are all covered with a flexible covering layer. In order to reduce the discomfort caused to the patient by the T-shaped sliding groove 11 during use, a towel can be filled into the exposed T-shaped sliding groove 11 after the position is adjusted.

[0023] By moving the sliding block 12 within the T-shaped groove, the distance between the two positioning fixation pillows 2 can be flexibly adjusted to adapt to different patient body shapes. Tightening the bolts to abut against the sliding block 12 can lock the position of the sliding block 12. At the same time, the positioning fixation pillow 2 is detachably inserted into the fixation groove 13 and connected to the sliding block 12 through the fixation post 21, which enhances the fixation stability and avoids displacement during the operation.

[0024] The body positioning pillow 2 includes a chest cushion 22 and a back cushion 23. The fixing posts 21 on the lower end surfaces of the chest cushion 22 and the back cushion 23 are both located in the middle and are respectively connected to the sliding blocks 12 at both ends of the T-shaped sliding groove 11. The length of the chest cushion 22 is less than the length of the back cushion 23.

[0025] The shorter chest pillow 22 and the longer back pillow 23 support different body parts, conforming more closely to the curves of the human body and reducing local pressure. The centrally positioned fixing post 21 improves the balance of the pillows, preventing tilting due to uneven pressure. Optionally, the detachable connection between the positioning pillow 2 and the base plate 1 allows the positions of the chest pillow 22 and the back pillow 23 to be interchanged after the patient is placed in a left or right lateral decubitus position, depending on the surgical site.

[0026] A knee-joint soft pillow 3 is located at the end of the base plate 1 away from the chest cushion 22 and the back cushion 23. A fixing post 21 is also provided on the lower end face of the knee-joint soft pillow 3, and the fixing post 21 is located at the end. A fixing groove 13 is also provided on the base plate 1, and the fixing post 21 can be detachably inserted into the fixing groove 13 to connect with the base plate 1. The soft pillow is placed on the patient's lower limbs to prevent the knee joint from being unsupported, increasing patient comfort.

[0027] The fixing post 21 is provided with first teeth 211 spaced circumferentially, and the fixing groove 13 is provided with second teeth 131 that can engage with the first teeth 211. After the fixing post 21 is detachably inserted into the fixing groove 13, the first teeth 211 and the second teeth 131 engage, which can restrict the rotation of the body position fixing pillow 2 and the knee joint soft pillow 3 during use. Furthermore, after the fixing post 21 is removed from the fixing groove 13, it can be rotated and adjusted before being reinserted into the fixing groove 13 for fixation. Therefore, the angles of the chest cushion 22, the back cushion 23, and the knee joint soft pillow 3 can be finely adjusted according to the patient's physiological curve, and the orientation of the knee joint soft pillow 3 can be adjusted after selecting the left lateral or right lateral position.

[0028] The base plate 1 includes a fixed plate 15 and a movable plate 16. An adjustment groove 161 is provided at one end of the movable plate 16 adjacent to the fixed plate 15. An extension plate 151 is provided at one end of the fixed plate 15. The extension plate 151 can be slidably inserted into the adjustment groove 161, and limit bolts 17 are provided at both ends of the adjustment groove 161. The limit bolts 17 can abut against the extension plate 151, fixing the fixed plate 15 and the movable plate 16 relatively. Similarly, to reduce the discomfort caused to the patient by the groove at the extension plate 151 during use, a towel can be filled into the exposed groove of the extension plate 151 after the position is adjusted.

[0029] The movable plate 16 extends and retracts via the extension plate 151, and the body positioning pillow 2 is set on the fixed plate 15, while the knee joint soft pillow 3 is set on the movable plate 16. This allows for adjustment of the distance between the body positioning pillow 2 and the knee joint soft pillow 3, adapting to patients of different heights and improving the versatility of the device.

[0030] When using the device, select the left or right lateral decubitus position according to the patient's surgical site. Then, place the chest cushion 22 and back cushion 23 on the patient's chest and back respectively. Adjust the angles of the chest cushion 22 and back cushion 23 according to the patient's physiological curves. Then, stretch the movable plate 16 outward according to the patient's height and tighten the limiting bolt 17 to fix it so that the knee joint soft pillow 3 can be placed under the patient's knee joint. After adjustment, insert the fixing post 21 into the fixing groove 13 to lock it. Finally, tighten the adjusting bolt 14 to lock the sliding block 12, which can effectively fix the patient's position.

[0031] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this utility model should be within the protection scope of this utility model.
