Abstract
Description
Technical Field
[0001] This utility model relates to the field of surgical instruments, and in particular to a restraint frame for lumbar puncture. Background Technology
[0002] Lumbar puncture typically requires the patient to be in a lateral decubitus position with hips and knees flexed and head flexed towards the chest to fully expose the intervertebral space. This procedure is suitable for diagnosing or treating central nervous system infections (such as meningitis), subarachnoid hemorrhage, intracranial pressure monitoring, or intrathecal drug administration.
[0003] This surgery is widely used across all age groups. Due to factors such as respiratory depression during anesthesia, young children are usually given local anesthesia or sedation during the surgery. This means that the patient still has a wide range of movement during the surgery. However, it is difficult to control young children during the surgery. There is also a lack of specific equipment for body position restraint in the current technology, which makes it difficult to maintain the body position, increases the risk of operation and the incidence of complications.
[0004] There is currently no corresponding solution to the above problems. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a simple structure that is suitable for restricting the position of patients during lumbar puncture surgery, especially for children.
[0006] The equipment includes a bed board, which serves as the assembly base for the equipment and also as the base surface for the patient to lie on during use.
[0007] The lower part of the bed board is provided with a popliteal fossa limiting block that slides upward, and a limiting block positioning mechanism is provided between the popliteal fossa limiting block and the bed board;
[0008] A backrest block is slidably provided above the middle of the bed board, and a block positioning mechanism is provided between the backrest block and the bed board.
[0009] Between the popliteal fossa limiting block and the backrest block, a chest and abdomen block is also provided on the bed board.
[0010] The effect achieved in this way is as shown in the attached diagram of the instruction manual. Figure 1 Based on the aforementioned chest and abdominal blocks, which serve as the limiting base for the chest and abdomen in the patient's lateral decubitus position, the popliteal fossa limiting block is pushed while the patient's knees are flexed, causing it to lock and engage in the popliteal fossa. Conversely, with the patient's head flexed towards the chest, the back blocks are pushed, serving as the limiting base for the patient's upper body to move backward, thus locking the patient's position in conjunction with the chest and abdominal blocks. This constrains the patient's intervertebral space to fully expose their body position, thereby assisting the patient in maintaining their posture.
[0011] The beneficial effects of this invention are: it solves the problem of the lack of postural restraint equipment in existing lumbar puncture surgery, making it suitable for people who have difficulty maintaining their posture due to forced positioning, especially young patients. Furthermore, the equipment has a simple structure, low cost, and is easy to maintain. Attached Figure Description

[0018] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0019] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides a lumbar puncture restraint frame, including a bed board 2, which is the assembly base of the device and also the lying base for the patient during use.
[0020] The lower part of the bed board 2 is provided with a popliteal fossa limiting block 4 that slides upward, and a limiting block positioning mechanism is provided between the popliteal fossa limiting block 4 and the bed board 2;
[0021] A backrest block 3 is slidably arranged above the middle part of the bed board 2, and a block positioning mechanism is provided between the backrest block 3 and the bed board 2.
[0022] Between the popliteal fossa limiting block 4 and the backrest block 3, a chest and abdomen block 1 is also provided on the bed board 2.
[0023] The effect achieved in this way is as shown in the attached diagram of the instruction manual. Figure 1Based on the aforementioned chest and abdomen block 1, which serves as the limiting base for the chest and abdomen in the patient's lateral decubitus position, the popliteal fossa limiting block 4 is pushed while the patient's knees are flexed, causing it to lock and engage in the popliteal fossa. With the patient's head flexed towards the chest, the back block 3 is pushed, serving as the limiting base for the patient's upper body to move backward, thus locking the patient's position in conjunction with the chest and abdomen block 1. This constrains the patient's intervertebral space to fully expose their body position, thereby assisting the patient in maintaining their posture.
[0024] In Example 1, a locking screw is provided on the popliteal fossa limiting block 4, the locking screw passes through the bed board 2, and a limiting block is provided at its tail end;
[0025] A locking screw sleeve is provided on the upper part of the locking screw, that is, on the upper part of the popliteal fossa limiting block 4.
[0026] In other words, by tightening the locking nut, the position of the popliteal fossa limiting block 4 can be fixed on the bed board 2.
[0027] Furthermore, the popliteal fossa limiting block 4 is in the form of a triangular truncated pyramid, and the angles of its three corners are gradually increased from small to large, and the lengths of its three sides are gradually increased from short to long.
[0028] Preferably, the angles of the three corners are 40°, 60° and 80° respectively.
[0029] The effect achieved in this way is that, based on embodiment 1, the popliteal fossa limiting block 4 can rotate on the bed board 2. With gradually changing angles and side lengths, it can not only slide to adapt to the body position, but also rotate to adjust the angle, so as to further adapt to different patient positions and achieve the purpose of comfortable restraint.
[0030] Furthermore, as shown in the attached diagram of the instruction manual. Figure 4 The popliteal fossa limiting block 4 has a base 5 at its bottom, and the outer diameter of the base 5 is not greater than the length and width of the popliteal fossa limiting block 4.
[0031] The effect achieved in this way is that the gap between the pad 5 and the popliteal fossa limiting block 4 provides a binding base, that is, as... Figure 1 As shown, when the patient uses the restraint frame for postural restraint, there is still room for forward flexion and extension of the lower leg; if necessary, the above-mentioned gap and the pad 5 can be used as the binding base to limit and restrain the leg by binding.
[0032] In Example 2, a locking screw is provided on the back stop 3, the locking screw passes through the bed board 2, and a limit block is provided at its tail end;
[0033] A locking screw sleeve is provided on the upper part of the locking screw, that is, on the upper part of the popliteal fossa limiting block 4.
[0034] This achieves the effect of quickly locking the device.
[0035] In Example 3, the back stop 3 is a round shaft.
[0036] In Example 4, the chest and abdomen block 1 is a round shaft.
[0037] This achieves the effect of avoiding injury.
[0038] In Example 5, the chest and abdomen block 1 is fixedly installed on the bed board 2.
[0039] The effect achieved in this way is to provide a fixed basis for the patient's body position.
[0040] In Example 6, the popliteal fossa limiting block 4, the back block 3, and the chest and abdomen block 1 are all provided with a flexible padding layer on their outside.
[0041] The effect achieved in this way is to improve the safety and comfort of use.
