Description

Technical Field

[0001] The invention relates to the field of medical surgical instruments, and in particular to a cervical anterior surgical position frame. Background Art

[0002] Anterior cervical spine surgery is generally a direct decompression, which can remove the intervertebral disc and osteophytes without directly interfering with the spinal cord. After decompression, intervertebral bone grafting is performed to remove spinal instability factors, including fusion fixation surgery and non-fusion surgery (cervical artificial disc replacement). People have seven cervical vertebrae and six cervical intervertebral discs, and most patients have a single cervical vertebra. If it is a single-segment lesion, anterior cervical spine surgery is definitely the first choice; there are relatively few patients with double-segment and more segmental lesions, so there are relatively fewer patients who undergo posterior surgery. The advantage of anterior surgery is that the trauma is very small and the patient recovers quickly. Generally, a small incision of 2 to 3 cm in front of the patient's neck can reach the front of the vertebral body, and the operation is performed along the muscle texture, which rarely damages the normal structure. The patient recovers quickly after surgery, and some patients can be discharged from the hospital in two or three days.

[0003] However, the risk of anterior approach surgery is higher than that of posterior approach surgery, because there are some very important structures in front of the cervical spine. On one side of the front of the cervical spine are large blood vessels, and on the other side are the trachea and esophagus. Therefore, if there are complications in anterior approach surgery, the complications are very serious. Therefore, it is extremely important to design a fixation device that can fix the patient's position and facilitate anterior approach surgery. We hope that the device can assist patients under anesthesia to assume a suitable position for anterior approach surgery. Based on this, a position frame for anterior approach surgery of the cervical spine is proposed. Summary of the invention

[0004] The present invention is intended to provide a body position frame for anterior cervical spine surgery, so as to solve the problem that it is difficult for a patient in an anesthetized state to maintain a body position suitable for anterior cervical spine surgery.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A body position frame for anterior cervical spine surgery comprises a base and a shoulder puller, wherein a pillow is arranged on the base, a neck pillow is arranged in the middle of the base, the neck pillow is connected to the base through a controllable lifting device, a headrest is arranged at one end of the base away from the pillow, and the headrest can adjust the height relative to the base, and the shoulder puller comprises a shoulder fixing part, a serpentine retractor and a bed fixing part, and the shoulder fixing part is connected to the bed fixing part through the serpentine retractor.

[0007] Furthermore, the controllable lifting device includes a hand-cranked screw lifter and a rocker. The hand-cranked screw lifter is arranged on a base and a top end is connected to a neck pillow. The rocker is axially connected to the hand-cranked screw lifter.

[0008] Furthermore, a screw rod is arranged at the bottom of the headrest, and a nut which is threadedly matched with the screw rod is axially connected to the base, and the height of the headrest is adjusted by rotating the nut.

[0009] Furthermore, the shoulder fixing piece is in the shape of a palm and is fixed on the patient's shoulder, and an anti-pressure pad layer is provided on the shoulder fixing piece.

[0010] Furthermore, the bed fixing part includes a head frame fixing part, and the head frame fixing part can be fixed on the operating bed.

[0011] Furthermore, an annular depression is provided in the middle of the headrest.

[0012] Furthermore, an operating table connecting rod is provided on the side of the base.

[0013] Furthermore, the pillow is fixed to the base by Velcro.

[0014] Furthermore, the headrest, neck rest and pillow are all provided with flexible cushion layers.

[0015] The principle and beneficial effects of this technical solution:

[0016] The present invention cushions the patient's shoulders with a pillow, and a neck pillow arranged in the middle of the base can adjust the height through a controllable lifting device. The patient's neck is lifted and fixed according to the length of the patient's neck. The headrest can drag the patient's head to prevent the head from tilting back excessively. Shoulder pullers are also arranged on both sides, one end of which is fixed to the operating table and the other end is arranged on the patient's shoulder. The patient's shoulder is pulled backward to avoid affecting the intraoperative C-arm fluoroscopic lateral view, so that the patient can be kept in a position convenient for anterior approach surgery.

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments:

[0023] like Figure 1-3 As shown, a cervical anterior surgery positioning frame includes a base and a shoulder puller. A pillow is arranged on the base, and the pillow is fixed to the base by Velcro. The position relationship relative to the base can be adjusted to accommodate patients of different body shapes. It should be noted that the pillow should have different sizes and specifications, and pillows of different sizes and specifications can be replaced by Velcro to meet the needs of different patients.

[0024] A neck pillow is arranged in the middle of the base, and the neck pillow is connected to the base through a controllable lifting device. The controllable lifting device includes a hand-cranked screw lifter and a rocker. The hand-cranked screw lifter is arranged on the base, and the top end is connected to the neck pillow. The rocker and the hand-cranked screw lifter are axially connected. The hand-cranked screw lifter generally includes a screw and a transmission shaft perpendicular to the screw, and the transmission shaft and the screw are transmitted through a bevel gear or a worm gear. In this embodiment, two hand-cranked screw lifters are arranged, and their transmission shafts are axially connected to each other to ensure synchronous lifting.

[0025] A headrest is arranged at one end of the base away from the pillow, and an annular depression is arranged in the middle of the headrest, which can fit the patient's head and ensure that the patient's head is not easy to shake left and right. A screw rod is arranged at the bottom of the pillow, and a nut threadedly matched with the screw rod is connected to the upper shaft of the base. The height of the headrest is adjusted by turning the nut to prevent the patient's head from tilting back excessively.
