Description

Technical Field

[0001] The utility model relates to the technical field of spinal surgery, in particular to a hard capsule membrane and a spinal cord protection device used for spinal surgery. Background Art

[0002] During spinal surgery, due to the greater hardness of the spine, bone knives, wire saws and other devices are usually required, in addition to the doctor's blunt or sharp cutting or sawing to complete the surgery. However, when the brute force is great, it is easy for the doctor to fail to apply force in time during the operation and cause collision with the spinal cord or dura mater around the patient's position, resulting in accidental injury to the patient.

[0003] In response to the above problems, the existing solution is usually to use metal retractors and other components to limit the doctor's movements, but this method can only provide limited protection for the dura mater and spinal cord and will cause obvious traction on the spinal nerves, which may also damage the spinal nerves if excessive. In addition, the dura mater and spinal cord themselves have a certain strength, and during surgery, it is only necessary to buffer the impact force to achieve the effect of protecting both. However, there is currently no solution in the existing technology that can protect the dura mater and spinal cord without affecting the doctor's movements. Summary of the invention

[0004] The utility model aims at solving the problems of the prior art and provides a dura mater and spinal cord protection device for spinal surgery, which has a simple structure and can directly protect the dura mater and the spinal cord.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The utility model provides a dura mater and spinal cord protection device for spinal surgery, comprising a protection body and two positioning rings, the two positioning rings are rotatably arranged at two ends of the protection body, and the two positioning rings are respectively used to stabilize the protection body after being clamped; the protection body is woven from metal wires, and the protection body is used to shield the dura mater and / or the front of the spinal cord to avoid accidental injury to the dura mater and the spinal cord during surgery.

[0007] Furthermore, fixing parts are respectively provided at both ends of the protection body, a rotating structure is provided at one end of the fixing part away from the protection body, and the positioning ring is rotatably connected to the rotating structure.

[0008] Furthermore, the rotating structure includes at least two clamping seats, which are mounted on the protective body, and the clamping seats are provided with clamping grooves, in which the positioning rings are clamped.

[0009] Furthermore, the positioning ring includes an arc-shaped portion and a mounting portion, two ends of the arc-shaped portion are respectively connected to two ends of the mounting portion, and the mounting portion is rotatably arranged in the rotating structure.

[0010] Furthermore, the fixing member is provided with a receiving groove at one end away from the rotating structure, and the receiving groove is used to receive the protective body; the fixing member is provided with a positioning hole connected with the receiving groove, and the positioning hole is used to receive part of the protective body.

[0011] Furthermore, the protective body has a thickness of 1-3 mm, a length of 2-4 cm, and a width of 1-3 cm. The thickness, length, and width may vary depending on the material used and the scope of surgery.

[0012] The beneficial effects of the utility model are as follows: the utility model has a simple structure, and the protective body is placed in front of the spinal cord and dura cyst membrane that need to be protected. The protective body is stabilized by clamping two positioning rings. When the spinal cord and / or dura cyst membrane is impacted because the doctor does not apply force in time, the protective body can buffer the impact force, so that the impact force applied to the spinal cord and / or dura cyst membrane is within an acceptable range, avoiding accidental trauma to the patient.

[0016] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0017] like Figure 1 and Figure 2 As shown, the utility model provides a dura mater and spinal cord protection device for spinal surgery, comprising a protection body 1 and two positioning rings 2, the two positioning rings 2 are rotatably arranged at both ends of the protection body 1, and the two positioning rings 2 are used to stabilize the protection body after being clamped; the protection body 1 is woven from metal wires, and the protection body 1 is used to shield the dura mater and the front of the spinal cord to avoid accidental injury to the dura mater and / or the spinal cord during surgery.

[0018] In actual use, the two positioning rings 2 are used to stabilize the protective body after being clamped, so that the protective body 1 can stably block the front of the spinal cord and / or the dura cyst. When the doctor uses too much force and fails to retract the force in time, resulting in a collision in the direction of the spinal cord and / or the dura cyst, it will first hit the protective body 1, and the protective body 1 will buffer and unload the force, so that the force applied to the spinal cord and / or the dura cyst is reduced to a size that the spinal cord and / or the dura cyst can bear, and even the impact force is completely absorbed by the protective body 1 and cannot be applied to the spinal cord and / or the dura cyst, thereby avoiding accidental injury to the spinal cord and / or the dura cyst.

[0019] In addition, the protective body 1 of the utility model is woven from metal wires, so that the protective body 1 has sufficient strength and a certain deformability, so that when the protective body 1 is impacted, it can be ensured that it will not be deformed too much, and has a certain hardness to ensure that the protective body 1 will not be deformed too much, so as to achieve a better protection effect.

[0020] In this embodiment, the two ends of the protection body 1 are respectively provided with fixing members 3, and the end of the fixing member 3 away from the protection body 1 is provided with a rotating structure 4, and the positioning ring 2 is rotatably connected to the rotating structure 4. The fixing member 3 plays the effect of fixing the two ends of the protection body 1, so that the protection body 1 is not easy to loosen, and the positioning ring 2 can be rotated relative to the protection body 1 through the setting of the rotating structure 4 to adapt to more shapes and postures of the spine.

[0021] In actual use, the rotating structure 4 includes at least two holders 5, which are mounted on the protective body 1. A slot 6 is provided at one end of the holder 5 away from the protective body 1, and the positioning ring 2 is clamped in the slot 6, that is, the positioning ring 2 is inserted into the slot 6 by clamping. The openings of the slots 6 of the two rotating structures 4 are opposite to each other, that is, after the positioning rings 2 are inserted into the slots 6, since the two positioning rings 2 are hung on two vertebrae respectively, they have the effect of cooperating with each other to straighten the protective body 1, that is, the positioning ring 2 has a tendency to move away from the opening of the slot 6 into which it is inserted, which can ensure that the positioning ring 2 does not separate from the slot 6 during use. Preferably, when the rotating structure 4 and the positioning ring 2 are assembled, the holder 5 itself is a plate-shaped structure. After the positioning ring 2 is placed on the plate-shaped structure, the holder 5 is formed by bending the plate-shaped structure, so that the holder 5 covers the positioning ring 2 when it is formed.

[0022] Specifically, the positioning ring 2 includes an arc portion 7 and a mounting portion 8, the two ends of the arc portion 7 are respectively connected to the two ends of the mounting portion 8, and the mounting portion 8 is rotatably arranged on the rotating structure 4. The mounting portion 8 is preferably in an elongated strip shape, so that the positioning ring 2 is a roughly semicircular structure, thereby avoiding having sharp corners that may easily cause harm to people around.

[0023] In this embodiment, the fixing member 3 is provided with a groove 9 at one end away from the rotating structure 4, and the groove 9 is used to accommodate the protective body 1; the fixing member 3 is provided with a positioning hole 10 connected to the groove 9, and the positioning hole 10 is used to accommodate part of the protective body 1.

[0024] Specifically, after the protective body 1 is loaded into the receiving groove 9, the fixing part 3 needs to be squeezed by external equipment to reduce the width of the receiving groove 9. During the squeezing process, the part of the protective body 1 in the receiving groove 9 that is opposite to the positioning hole 10 enters into the positioning hole 10, and reliable fixation between the protective body 1 and the fixing part 3 can be achieved without the use of welding or glue. This ensures that when the utility model is used, no welding residues or glue will come into contact with the patient's body and cause harm to the patient's body.

[0025] In this embodiment, the thickness of the protective body 1 is usually 1-3mm, which can ensure that the doctor's actions will not be interfered with too much when the utility model is used; the length of the protective body 1 is usually 2-4cm, and the width is usually 1-3cm. According to the different manufacturing materials and surgical scopes, the utility model of multiple specifications can be manufactured according to but not limited to the above length and width data. According to the thickness, length, and width of the position to be protected, one or more of the utility models can be selected for use or combined use, thereby achieving the effect of multiple specifications of protection.

[0026] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the utility model, which does not depart from the content of the technical solution of the utility model, belongs to the scope of the technical solution of the utility model.
