Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a perforating guide needle for minimally invasive endoscopic lumbar discectomy. Background Art

[0002] The intervertebral foraminal endoscope is a tube equipped with a light. It enters the intervertebral foramen from the side or back of the patient's body (either flatly or obliquely) and performs surgery in the safe working triangle. When the surgery is performed outside the annulus fibrosus of the intervertebral disc, the protruding nucleus pulposus, nerve roots, dura mater sac and hyperplastic bone tissue can be clearly seen under direct endoscope vision. Then various forceps are used to remove the protruding tissue, bone is removed under the microscope, and radiofrequency electrodes are used to repair the damaged annulus fibrosus. The surgery has minimal trauma: the skin incision is only 7mm, the size of a soybean, the bleeding is less than 20ml, and only one stitch is needed after the operation. It is the minimally invasive treatment for intervertebral disc herniation with the least trauma to the patient and the best effect among similar surgeries. During the operation, the doctor uses the tool to puncture the cervical intervertebral disc, and uses the working cannula as a channel, and then inserts the radiofrequency and other operating tools through this channel. During this operation, it is first necessary to puncture the lesion site safely and accurately. The current punching guide needle has a tube body inside the guide rod that lacks a locking structure, which makes it easy to loosen and fall off. For this reason, we propose a punching guide needle for minimally invasive perforaminal endoscopic lumbar disc surgery. Utility Model Content

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a perforating guide needle for minimally invasive percutaneous endoscopic lumbar disc surgery. The locking rod is combined with the locking hole to facilitate the fixation of the needle body. At the same time, the tube body installed subsequently can be clamped after the needle body is pulled out, thereby preventing the tube body from loosening. The sliding adjustment frame can adjust the position of the limit plate to facilitate personnel to effectively limit the insertion depth of the guide rod, which can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a perforation guide needle for minimally invasive transforaminal endoscopic surgery, comprising a handle and a pull handle;

[0005] Handle: A guide rod is fixed in the middle of the right side, a mounting slot is provided inside the handle, through slots are provided on both sides of the top surface of the handle, the handle is correspondingly plugged into the inside of the mounting slot, a needle body is fixed in the middle of the right side of the handle, and the needle body is slidably connected to the inside of the guide rod;

[0006] It also includes a locking rod and a locking hole. The locking rod is slidably connected to the inside of the through slot. The inner side of the locking rod is provided with a clamping groove, and the locking hole is provided in the middle of the side of the handle.

[0007] The handle installed inside the mounting groove allows the needle body to be inserted into the inside of the guide rod, thereby facilitating minimally invasive puncture of the patient's lumbar spine, and the corresponding connection between the locking rod and the locking hole facilitates the disassembly and assembly of the handle.

[0008] Furthermore, it also includes an adjusting frame, a fixing bolt and a limit plate. The adjusting frame is slidably connected to the outer side of the guide rod, and the axial hole on the surface of the adjusting frame is threadedly connected with the fixing bolt. The limit plate is fixed on the right side of the adjusting frame. The fixing bolt is rotated to fix the adjusting frame to a suitable position outside the guide rod. In this way, the limit plate is fixed, thereby effectively limiting the insertion depth of the guide rod.

[0009] Furthermore, it also includes a rotating wheel and an adjusting screw, the rotating wheel is fixed to the side of the handle, the adjusting screw is rotatably connected to the inside of the through groove, the outer end of the adjusting screw is connected to the inner end of the rotating wheel, and the adjusting screw is threadedly connected to the screw hole in the middle of the locking rod. Rotating the rotating wheel drives the adjusting screw to rotate, thereby adjusting the position of the locking rod to facilitate disassembly and assembly by personnel.

[0010] Furthermore, it also includes an anti-slip pad and an insertion rod. The outer side of the anti-slip pad is fixed with an insertion rod, and the insertion rod is plugged into the clamping groove on the inner side of the locking rod. The insertion rod is inserted into the clamping groove on the inner side of the locking rod to fix the anti-slip pad, thereby preventing the problem of loosening and falling off when the tube body is clamped later.

[0011] Furthermore, it also includes an arc-shaped gripping groove and an anti-slip strip. There are two arc-shaped gripping grooves, which are respectively opened at the two ends of the right side of the handle. The anti-slip strips are evenly distributed in the middle of the top surface of the handle. The opened arc-shaped gripping grooves are convenient for people to hold with their hands, and the set anti-slip strips can increase the stability of people's hand holding.

[0012] Furthermore, it also includes a protective coating, which is evenly coated on the outside of the guide rod. The protective coating is Teflon coating. The protective coating can increase the corrosion resistance of the guide rod to prevent the guide rod from being corroded by oxidation.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the perforation guide needle for minimally invasive transforaminal endoscopic surgery has the following advantages:

[0014] 1. The needle body is inserted into the inside of the guide rod through the handle installed inside the mounting groove, thereby facilitating minimally invasive puncture of the patient's lumbar spine, and the corresponding connection between the locking rod and the locking hole facilitates the disassembly and assembly of the handle.

[0015] 2. Fix the adjustment frame to the appropriate position outside the guide rod by turning the fixing bolts, so as to fix the limit plate and effectively limit the insertion depth of the guide rod. Insert the insertion rod into the clamping groove on the inner side of the locking rod to fix the anti-slip pad, thereby preventing the tube body from loosening and falling off when it is clamped later.
