Minimally invasive spinal internal fixation surgical device

This creation department is related to the innovation of a minimally invasive spinal internal fixation implant device, especially the combination of the support mechanism and the operating bed, and the adjustment of the first and second levers with the support mechanism, the guide rail and the slide seat, Second pull hook and sleeve to the surgical site, after confirming the internal fixation into the nail point, the surgical tool and the internal fixation implant are inserted into the sleeve for surgery, and the nail insertion point can be accurately confirmed by simple operation. The position is achieved, and the wound caused by the operation is small, the damage of the muscle tissue is not obvious, the amount of bleeding is small, the time for the surgeon to expose the X-ray is short, and the patient recovers quickly after the operation.

According to the medical profession, when performing intrathecal fixed implantation, a line is usually drawn in the middle of the patient's back, and the skin, fascia, aponeurosis and supraspinous ligament are sequentially cut with a surgical tool, and the muscles of the spine are (Multiple lobes), which are removed along the periosteum to the facet joints and transverse processes, and are hooked to the two sides. However, such surgical procedures require many tendons and ligaments attached to the spine to be cut off. The lamina, the posterior spinous process, the interspinous ligament, and the ligamentum flavum must be removed together to achieve the purpose of decompression of the nerve. Therefore, some bone soft tissue, muscle, tendon, and ligament are destroyed, resulting in the following Missing:

1. When the muscle is sutured after the operation is completed, the muscles and tendons cannot be attached back to the section before the opening. The original position violates and destroys the physiological structure of the patient.

2. The dead space after the completion of the operation is too large, which may cause the muscle fibrosis after the operation, resulting in poor surgical results.

3. Because the soft tissue around the spine is extensively removed and exfoliated, it is easy to cause instability of the vertebral column after surgery.

4. The amount of bleeding during the operation is high, which may require a large amount of blood transfusion. However, if there is abnormal blood supply in allogeneic blood transfusion, it may cause complications such as allergies and infections.

In order to solve the above-mentioned lack of surgery, medical professionals have developed another minimally invasive surgical device that makes the wound small and has less tissue damage. However, for the minimally invasive surgical device currently used by the medical profession, regardless of the intradermal fixation There are still the following defects in the way of entering, or adopting a small incision to open:

1. This type of surgery must remove the intervertebral disc or expand and decompress the spinal canal. However, the minimally invasive surgical device, such as the method of intradermal fixation alone, cannot perform the discectomy or the enlargement or reduction of the spinal canal. Pressure.

2. Such surgical surgeons must be exposed to X-ray fluoroscopy for a long time. It is only necessary to confirm the position of the internal fixation point by both hands, but it is difficult to increase the operation of the operation.

3. The surgical technique of this type is too high, so that the surgical surgeons must apply long-term professional training to perform the operation in the above manner.

The main purpose of this creation is to avoid the persistence of the above-mentioned formulas. The support mechanism can be combined with the operating bed, and the first and second pull rods and the first and second pull hooks and the sleeve are adjusted to the surgical site by using the support mechanism, the guide rail and the sliding seat, and after the internal fixation point is confirmed, The surgical tool and the internal fixation implant are inserted into the sleeve for surgery. The simple operation can accurately confirm the position of the nail point, and the wound caused by the operation is small, the muscle tissue destruction is not obvious, and the blood is traced. The time that the surgeon is exposed to X-rays and the rapid recovery of the patient after surgery.

In order to achieve the above purpose, the present invention is a minimally invasive intraspinal implant surgical device comprising a support mechanism; a guide rail coupled with the support mechanism; at least two corresponding slides respectively coupled to the guide rail; The sliding rod is combined with the first pull rod, which comprises at least one metal arm and a plastic arm combined with the metal arm; and a second pull rod combined with the other sliding seat, which comprises at least one metal arm, and one metal a plastic arm combined with an arm; a first pull hook combined with a plastic arm provided by the first pull rod; a second pull hook combined with a plastic arm provided with the second pull rod; and a sleeve disposed on a side of the first pull hook a cartridge; and a detector that is inserted into the sleeve for positioning and sounding and then removed.
