Description

Technical Field

[0001] This utility model relates to the field of minimally invasive spinal surgery technology, specifically a channel suture pusher. Background Technology

[0002] Currently, minimally invasive surgery is the main surgical method and development direction for spinal cord-related diseases. Among them, spinal micro-channel surgery is one of the main minimally invasive surgical methods, and the number of surgeries performed each year is increasing year by year.

[0003] Subdural tumors within the spinal canal often require incision of the dura mater because the tumor is located beneath it. During microsurgical procedures using a microchannel, the surgeon must complete the incision, tumor removal, and suturing of the dura mater within this microchannel. The microchannel has an outer diameter of 14-18 mm, an internal diameter of 11-15 mm, and a depth of 70-100 mm. The depth from the microchannel opening to the dural suture site is typically 80-120 mm. Due to the limited space and deep suture site, conventional suturing instruments cannot reach the dural opening. Furthermore, the dural suture sutures are extremely fine, commonly using 6-0 or 7-0 sutures (0.1-0.3 mm in diameter). Without suitable microsurgical instruments, dural suturing is very difficult and prone to complications such as cerebrospinal fluid leakage and intracranial infection.

[0004] In minimally invasive surgery for lumbar disc herniation or lumbar spinal stenosis, due to the long medical history, the ligaments and osteophytes in the spinal canal often adhere to the dura mater, and dura mater injury frequently occurs during the operation. Currently, there is a lack of professional instruments and tools, and the dura mater is difficult to suture. Postoperative complications often include cerebrospinal fluid leakage and intracranial infection, causing serious sequelae to patients. Utility Model Content

[0005] The purpose of this invention is to provide a channel pusher to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a channel pusher, comprising a handle portion with a rod portion welded to one end, the top end of the rod portion having claw-shaped pusher portions for pushing the line, the rod portion and the handle portion forming an obtuse angle, and each of the claw-shaped pusher portions being 30° apart.

[0007] Preferably, the angle between the handle portion and the rod portion is 160°.

[0008] Preferably, there are three claw-shaped pusher parts, each 0.4 cm long and 0.2 cm in diameter.

[0009] Preferably, the handle portion is 4cm long and 1cm in diameter.

[0010] Preferably, the rod portion is 15cm long and 0.3cm in diameter.

[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: The physician then holds the handle of the channel pusher and uses the gap within the forked claw-shaped pusher at the outer opening of the microchannel to hold the suture knot, preventing slippage. After the claw-shaped pusher secures the suture knot, it is slowly pushed into the microchannel, gradually approaching and finally reaching the dura mater suture site. The angle and direction of the claw-shaped pusher are adjusted, and the suture knot is gently rotated and pressed, ensuring a tight fit at the dura mater suture edge and a secure knot, thus completing one suture knotting operation within the channel. This operation is repeated 3-5 times, completing 3-5 suture knots, achieving the suture knotting operation for microsurgical sutures within the channel, ultimately enabling assisted dura mater suturing surgery within the channel. This device features compact instruments, unobstructed surgical field, wide applicability, and secure knotting. In spinal microchannel surgery, it assists in dura mater suturing, reducing postoperative cerebrospinal fluid leakage and serious complications such as intracranial infection. Therefore, this invention has excellent practical effects. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: the handle part 1 is the part where the doctor holds the instrument, 4cm long, cylindrical, and 1cm in diameter. The handle is compact and the cylindrical shape provides a firm grip;

[0020] Rod part 2 is welded to one end of handle part 1. Rod part 2 is 15cm long, cylindrical, and 3mm in diameter, forming a 70° angle with the handle. The rod is thin and forms an obtuse angle with handle part 1, which can avoid obstructing the field of vision within the microchannel and allow for better observation of the dura mater areas that need suturing.

[0021] The claw-shaped pusher part 3 is located at the top of the rod part 2. There are three claw-shaped pusher parts 3, arranged in a three-finger shape. Each finger is cylindrical, 2mm in diameter and approximately 4mm long, with an angle of 30° between each finger. The claws form a 110° angle with the rod. The claw-shaped pusher part 3 is the main part assisting in dural suturing, pushing the suture to be knotted to the knotting site to complete the knotting operation. It is suitable for assisting in suturing the dura mater in narrow and deep microchannels and is suitable for dural suturing in different spinal canal locations.

[0022] It is suitable for minimally invasive surgery with microchannels for spinal cord-related diseases, and can efficiently and stably assist in suturing the dura mater.

[0023] The steps involved in suturing the dura mater during microcanal spinal surgery include:

[0024] (1) At the opening of the microchannel, the physician uses a micro-needle holder to pass the micro-suture needles (6-0, 7-0) through the edges of the dura mater on both sides of the dura mater gap;

[0025] (2) During the process of knotting the micro-threads (6-0, 7-0), the physician knots the threads at the outer opening of the microchannel.

[0026] Because the internal diameter of the channel is 11-15mm, and the depth from the microchannel opening to the dura mater suture site is typically 80-120mm, the suture knot cannot directly reach the dura mater suture site. Furthermore, the suture diameter is only 0.1-0.3mm, making fixation difficult; it can only reach the microchannel opening. The physician then holds the handle 1 of the channel pusher and uses the gap within the forked claw-shaped pusher 3 at the microchannel opening to hold the suture knot, preventing slippage. After the claw-shaped pusher 3 secures the suture knot, it is slowly pushed into the microchannel, gradually approaching and finally reaching the dura mater suture site. The angle and direction of the claw-shaped pusher 3 are adjusted, and the suture knot is gently rotated and pushed to ensure tight alignment of the dura mater suture edges and a secure knot, completing one suture knotting operation within the channel. This operation is repeated 3-5 times, completing 3-5 suture knots, achieving the suture knotting operation for microsurgical sutures within the channel, ultimately enabling the auxiliary dura mater suturing procedure within the channel.

[0027] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
