Description

Technical Field

[0001] The invention relates to the technical field of cervical vertebra retractors, in particular to a cervical vertebrae nail-shaped soft tissue retractor with a suction function. Background Art

[0002] The cervical vertebrae refer to the cervical vertebrae, which are located below the head and above the thoracic vertebrae. They are located in the cervical spine and consist of 7 vertebrae, surrounding the cervical cord and its spinal meninges. They are connected by intervertebral discs and ligaments, forming a physiological curvature that convexes forward. The characteristics of the cervical vertebrae are that the vertebral bodies are small and oval, with transverse foramina on the transverse processes, through which the vertebral arteries and vertebral veins pass; the spinous processes are short and bifurcated; the joints of the upper and lower articular processes are approximately horizontal, allowing the neck to move flexibly. The upper and lower notches of adjacent vertebrae form intervertebral foramina, through which spinal nerves and blood vessels pass.

[0003] There is a lot of soft tissue in the cervical spine, and the soft tissue often blocks the field of vision during surgery, making the surgery very inconvenient. In addition, existing retractors have different shapes and are large in size. Since the cone head cannot be replaced, they cannot be applied to different patients. Summary of the invention

[0004] The purpose of the present invention is to provide a nail-shaped soft tissue retractor with a cervical vertebrae suction function to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a nail-shaped soft tissue retractor with a suction function for the cervical spine, comprising a nail-shaped retractor body, a side end portion of the nail-shaped retractor body being penetrated by a suction side hole, an upper end portion of the nail-shaped retractor body being fixedly installed with an arc-shaped pipe, an upper end portion of the nail-shaped retractor body located on the left side of the arc-shaped pipe being fixedly installed with a connecting rod, a nail body being installed with a nail body at the lower end portion of the nail-shaped retractor body, a nail tip being fixedly installed with a ring-shaped rod at the upper end portion of the nail body, an ring-shaped rod groove being opened at the lower end portion of the nail-shaped retractor body, the nail-shaped retractor body and the nail body being connected by the ring-shaped rod and the ring-shaped rod groove, an expansion groove being opened at the side end portion of the nail-shaped retractor body, and at least two expansion plates being movably installed in the expansion groove.

[0006] Preferably, three clips are installed on the side end of the nail-shaped hook body located on the left side of the expansion slot, a tail cap is fixedly installed on the upper end of the connecting rod, and two hook frames are fixedly installed on the upper ends of the nail-shaped hook body located on both sides of the connecting rod, each of the hook frames has a J-shaped cross-section, and inner grooves are provided on the inner walls of the two hook frames.

[0007] Preferably, screw grooves 2 are provided between the front and rear sides of the nail-shaped hook body and the annular rod groove, a rubber sleeve is fixedly installed inside each of the screw grooves 2, an elliptical rubber block is fixedly installed at the lower end of the nail-shaped hook body located inside the annular rod groove, the elliptical rubber block is located inside the annular rod, and screw grooves 1 are provided on the front and rear side walls of the annular rod.

[0008] Preferably, the left and right side walls of the inner wall of the expansion slot are each provided with at least two side slide rails, and two side slide frames are horizontally slidably installed between the two parallel left and right side slide rails, and each two side slide frames are rotatably connected to the same expansion plate, and a side groove is provided at the upper end of each expansion plate.

[0009] Preferably, at least two rear rubber blocks are fixedly installed on the inner wall of the expansion slot located on the rear side of the expansion board, and at least two front rubber blocks are fixedly installed on the inner wall of the expansion slot located on the front side of the expansion board, and each of the rear rubber blocks and the front rubber blocks are provided with rubber blocks on their opposite surfaces.

[0010] The present invention has the following beneficial effects:

[0011] First, medical staff can use a hammer to knock on the tail cap, and the force of the tail cap is transmitted to the connecting rod, and the force of the connecting rod is transmitted to the nail-shaped retractor body, and the force of the nail-shaped retractor body is transmitted to the nail body, and the force of the nail body is transmitted to the nail tip, and the nail tip gradually enters the patient's vertebral body, and can be connected to the suction device through an arc-shaped pipe. The arc-shaped pipe is an arc-shaped pipe, which is directly backward and can play a role in blocking soft tissue. This device can block soft tissues such as the longus colli muscle, carotid sheath, sternocleidomastoid muscle, and skin, which helps to clearly expose the surgical area and avoid the surgeon's side assistant retractor affecting the surgical operation. At the same time, connecting the suction device can attract blood during the operation to keep the field of vision clear.

[0012] Secondly: insert nail tips of different shapes into the annular rod grooves provided in the nail-shaped retractor body through the annular rod at the upper end of the nail tip. At this time, the lower end of the elliptical rubber block contacts the inner wall of the annular rod, and the lower end of the elliptical rubber block adheres to the upper end of the nail body, which has a better fixing effect. After the upper end of the nail body fits with the lower end of the nail-shaped retractor body, screw groove one and screw groove two will be aligned. At this time, medical staff can rotate the screw to fix the nail body to the nail-shaped retractor body. Due to the different bone qualities of different patients, different shapes of nail tips are required for fixation. This device can meet the needs of different patients by directly replacing the nail tip without replacing the entire nail-shaped retractor body, thereby providing convenience for surgery.

[0013] Third: When medical staff need to replace the nail tip, they first insert the screw into the second screw slot, and the screw enters the inside of the rubber sleeve. The rubber sleeve will clamp the screw. Since the screw is small, it is difficult to find once it falls off. Therefore, it is preferred to simply fix the screw to effectively prevent the screw from falling off during installation.

[0014] Fourthly, the expansion plate is pulled out of the nail-shaped retractor body, and the expansion plate rotates due to the force, and the expansion plate drives the two side slides to move outward at the same time. Both side slides slide in the side slide rails provided in the expansion slot, and the expansion plate stops when it moves and contacts the front rubber block plate. By utilizing the multiple expansion plates in the expansion slot for extension, the overall blocking range of the nail-shaped retractor body is further effectively increased, thereby preventing accidents caused by insufficient blocking area during surgery.

[0015] Fifth: a rubber block is provided on the contact surface between the front rubber block plate and the extension plate, so the extension plate will be stuck to the rubber block when it contacts the front rubber block plate; when the extension plate is moved and reset by medical staff, the back of the extension plate will contact the rubber block on the surface of the rear rubber block plate, and the extension plate will be stuck to the rear rubber block plate. By using the front rubber block plate and the rear rubber block plate to fix the extension plate in different states, the stability of the extension plate in different states is effectively guaranteed, and the problem of displacement of the extension plate due to surgical shaking is effectively prevented, thereby greatly improving the stability of the blocking.

[0016] Sixth, tools can be inserted into the two hook frames, and the tools will be inserted into the two inner grooves of the hook frames. At this time, the tool is pulled upward with force, and the force on the two hook frames will drive the nail-shaped retractor body to move, thereby playing an auxiliary pulling-out role, greatly reducing the shaking of the nail-shaped retractor body when it is removed, and reducing the patient's pain.

Rubber blocks are provided on the opposite surfaces of each rear rubber plate 31 and front rubber plate 32.

[0036] Working principle:

[0037] The first step is anterior cervical surgery. After the front of the vertebral body is exposed, the medical staff fixes the nail-shaped retractor body 1 to the side of the cervical vertebral body. The medical staff can use a hammer to knock the tail cap 15. The tail cap 15 is subjected to force and transmitted to the connecting rod 14. The connecting rod 14 is subjected to force and transmitted to the nail-shaped retractor body 1. The nail-shaped retractor body 1 is subjected to force and transmitted to the nail body 2. The nail body 2 is subjected to force and transmitted to the nail tip 21. The nail tip 21 gradually enters the patient's vertebral body. The length of the nail tip 21 is 1.5 cm. The cylindrical part of the nail-shaped retractor body 1 is 5.5 mm long from left to right and 3.5 mm long from front to back. It is oblate in shape. The hollow pipe is the same as the tail end. At the same time, the nail-shaped retractor The main body 1 can be adjusted within the range of 5-8cm by the buckle 12, and can be connected to the suction device through the arc pipe 13. The arc pipe 13 is an arc pipe, facing directly backward, which can play a role in blocking soft tissue. The distance between the buckle 12 and the arc pipe 13 is 3.5cm, and the distance between the arc pipe 13 and the main body of the nail-shaped retractor 1 is 2.5cm. The overall function of this device is to block soft tissues such as the longus colli muscle, carotid sheath, sternocleidomastoid muscle, and skin, which helps to clearly expose the surgical area and avoid the operator's side assistant retractor affecting the surgical operation. At the same time, connecting the suction device can attract blood during the operation and keep the field of vision clear.

[0038] In the second step, when the medical staff needs to replace the nail tip 21, the screw is first inserted into the screw groove 26, and the screw enters the inside of the rubber sleeve 27. The rubber sleeve 27 will clamp the screw. Since the screw is small, it is difficult to find it once it falls off. Therefore, it is preferred to simply fix the screw to effectively prevent the screw from falling off during installation. The medical staff can insert the nail tip 21 of different shapes into the annular rod groove 25 opened in the nail-shaped retractor body 1 through the annular rod 22 at the upper end of the nail tip 21. At this time, the lower end of the elliptical rubber block 24 is in contact with the inner wall of the annular rod 22. The lower end of the elliptical rubber block 24 adheres to the upper end of the nail body 2, which has a better fixing effect. After the upper end of the nail body 2 is fitted with the lower end of the nail-shaped retractor body 1, the screw groove 1 23 and the screw groove 2 26 will be aligned. At this time, the medical staff can rotate the screw to fix the nail body 2 and the nail-shaped retractor body 1. Due to the different bone qualities of different patients, different forms of nail tips 21 are required for fixation. The device directly replaces the nail tip 21 without replacing the entire nail-shaped retractor body 1, thereby meeting the needs of different patients and providing convenience for surgery.

[0039] In the third step, when the medical staff needs to increase the blocking area of ​​the nail-shaped retractor body 1, the medical staff can use medical tools to contact the side groove 36 at the upper end of the expansion plate 35, and gently pull the expansion plate 35 toward the outside of the nail-shaped retractor body 1. The expansion plate 35 will rotate under the force, and at the same time, the expansion plate 35 will drive the two side slides 34 to move outward. The two side slides 34 both slide in the side slide rails 33 opened in the expansion slot 3. When the expansion plate 35 moves and contacts the front rubber block plate 32, it stops. By using multiple expansion plates 35 in the expansion slot 3 to stretch, the overall blocking range of the nail-shaped retractor body 1 is further effectively increased to prevent accidents caused by insufficient blocking area during surgery.

[0040] Since the contact surface between the front rubber block plate 32 and the expansion plate 35 is provided with a rubber block, the expansion plate 35 will be stuck to the rubber block when it contacts the front rubber block plate 32. When the expansion plate 35 is moved and reset by the medical staff, the back side of the expansion plate 35 will contact the rubber block on the surface of the rear rubber block plate 31, and the expansion plate 35 will stick to the rear rubber block plate 31. By using the front rubber block plate 32 and the rear rubber block plate 31 to fix the expansion plate 35 in different states, the stability of the expansion plate 35 in different states is effectively guaranteed, and the problem of displacement of the expansion plate 35 due to surgical shaking is effectively prevented, thereby greatly improving the stability of the block.

[0041] In the fourth step, when the medical staff needs to pull out the nail-shaped retractor body 1, the medical staff can insert the tool into the two hook frames 16, and the tool will be inserted into the two inner grooves 17 opened by the hook frames 16. At this time, the tool is pulled upward with force, and the two hook frames 16 will be driven by force to move the nail-shaped retractor body 1, thereby playing an auxiliary pulling-out role, greatly reducing the shaking of the nail-shaped retractor body 1 when it is taken out, and reducing the patient's pain.

[0042] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
