技术领域technical field

本实用新型有关于一种微创脊椎内固定植入手术装置，尤指可将支撑机构与手术床结合，且利用支撑机构、导轨及滑座的配合，调整第一、二拉杆与第一、二拉钩及套筒至手术部位，待确认内固定入钉点后，再将手术工具与内固定植入物自套筒伸入以进行手术，藉由简易的操作，可精准确认入钉点的位置，而达到手术造成的伤口微小、肌组织破坏不明显、出血微量、手术执刀人员所曝现于X射线的时间短以及患者手术后恢复迅速的功效。 The utility model relates to a minimally invasive spinal internal fixation and implantation operation device, especially a supporting mechanism which can be combined with an operating bed, and which can be adjusted by using the cooperation of the supporting mechanism, guide rails and sliding seats to adjust the first and second pull rods to the first and second pull rods. Two retractors and sleeves to the surgical site. After the internal fixation entry point is confirmed, the surgical tools and internal fixation implants are inserted through the sleeve for surgery. With simple operation, the entry point can be accurately confirmed. Position, so as to achieve the effects of small wounds caused by surgery, no obvious damage to muscle tissue, minimal bleeding, short exposure time to X-rays for surgical personnel, and rapid recovery of patients after surgery. the

背景技术Background technique

医界在进行脊椎内固定植入手术时，通常是在患者背部的正中间划一剖线，依序以手术工具切开皮肤、筋膜、腱膜以及棘上韧带，而将脊椎旁的肌肉（多裂肌），沿着骨膜剥离至小关节突与横突的部位，并以勾具勾向二侧固定，但如此的手术步骤，使得众多附着于脊椎上的肌腱与韧带则必须切断，且又必须将椎板、后棘突、棘间韧带以及黄韧带一并切除以达到神经得以减压的目的，因此连带造成部分骨质软组织、肌肉、肌腱以及韧带等的破坏，而产生有以下缺失： When the medical community performs spinal internal fixation implantation surgery, it usually draws a section line in the middle of the patient's back, and uses surgical tools to incise the skin, fascia, aponeurosis, and supraspinous ligament in sequence, and the muscles next to the spine ( multifidus muscle), stripped along the periosteum to the facet joint process and transverse process, and hooked to both sides for fixation, but such an operation procedure requires that many tendons and ligaments attached to the spine must be cut off, and In addition, the lamina, posterior spinous process, interspinous ligament, and ligamentum flavum must be resected together to achieve the purpose of decompression of the nerve. Therefore, part of the bone and soft tissue, muscles, tendons, and ligaments will be damaged, resulting in the following defects: :

1.当手术完成肌肉缝合后，肌肉与肌腱无法贴回剖开前的原来位置，违背并破坏患者的生理结构。 1. After the muscle suturing is completed, the muscles and tendons cannot be attached to their original positions before the incision, which violates and destroys the patient's physiological structure. the

2.手术完成后的死空间（dead space）过大，易造成手术后的肌肉沾黏（epidural fibrosis），致使手术效果不佳。 2. The dead space after the operation is too large, which can easily cause epidural fibrosis after the operation, resulting in poor surgical results. the

3.由于脊椎旁的软组织遭广泛切除与剥离，易造成手术后的椎柱不稳定。 3. Due to the extensive resection and stripping of the soft tissue next to the spine, it is easy to cause instability of the vertebral column after surgery. the

4.手术过程的出血量多，导致可能需要大量输血，但异体输血如出现供血异常，有可能引发患者出现过敏、感染等并发症状。 4. The amount of blood loss during the operation may be large, which may require a large amount of blood transfusion. However, if the blood supply is abnormal during allogeneic blood transfusion, it may cause complications such as allergies and infections in patients. the

为解决上述手术的缺失，医界人员而后研发出另一使伤口小且组织破坏少的微创手术装置，然就目前医界所使用的微创手术装置而言，无论是采用皮内固定植入，或采用小切口撑开的方式，均仍有以下缺失： In order to solve the shortage of the above-mentioned operations, medical personnel then developed another minimally invasive surgical device with small wound and less tissue damage. However, there are still the following defects:

1.这类的手术过程必须切除椎间盘或针对椎管进行扩大减压，然上述微创手术装置如仅采用皮内固定植入的方式，无法一并进行椎间盘的切除或椎管的扩大减压。 1. This type of surgery must remove the intervertebral disc or expand and decompress the spinal canal. However, if the above-mentioned minimally invasive surgical devices are only implanted with intradermal fixation, the intervertebral disc cannot be removed or the spinal canal should be expanded and decompressed. . the

2.这类的手术执刀人员必须长时间曝现于X射线的透视下，仅靠双手确认内固定的入钉点位置，只是徒增手术操作的困难。 2. The operators of this type of surgery must be exposed to X-ray fluoroscopy for a long time, and only rely on their hands to confirm the position of the entry point of the internal fixation, which only increases the difficulty of the operation. the

3.这类的手术操作技术门坎过高，致使资浅的手术执刀人员必须施以长时间的专业训练才可按上述方式进行手术。 3. The technical threshold for this type of surgical operation is too high, so that junior surgical staff must undergo a long period of professional training before performing the operation in the above-mentioned manner. the
