Description

Technical Field

[0001] This utility model relates to the field of spinal surgery technology, specifically a surgical knife used in spinal surgery. Background Technology

[0002] Spinal surgery is a medical procedure used to treat serious spinal problems (such as herniated discs, fractures, deformities, etc.) by relieving symptoms through structural repair, nerve compression relief, or spinal stabilization. Common surgical types include discectomy, spinal fusion, and vertebroplasty. Postoperative rehabilitation and long-term management are crucial for recovery. Specialized spinal scalpels are required during spinal surgery, but most common scalpels are one-piece disposable blades. In practice, it is often inconvenient to adjust the length of the handle to suit the patient's needs, leading to discomfort and impacting the spinal surgery. This means the scalpel cannot adequately meet the requirements of spinal surgery.

[0003] During the design process of this utility model, the following problems were found in the existing technology: Most of the scalpels used in common spinal surgeries are disposable scalpels with an integrated structure. When using them, it is often inconvenient to adjust the length of the handle according to the patient's condition, resulting in a poor grip on the scalpel, which has a certain impact on spinal surgery, and thus the scalpel cannot well meet the needs of spinal surgery.

[0024] A negative magnet 201 is installed at one end of the extended handle 2, an extension groove 202 is embedded in one end of the extended handle 2, a locking screw 203 is threaded through the top end of the extended handle 2, a limiting groove 204 is passed through the bottom of the extension groove 202, and a positioning groove 205 is embedded in the top inner wall of the limiting groove 204.

[0025] The top of the extension handle 3 is fitted with a locking groove 301, and the bottom end of the extension handle 3 is fitted with an inset groove 302. A reset damping spring 303 is installed inside the inset groove 302. A positioning block 304 is installed at the bottom end of the reset damping spring 303, and a pressing block 305 is installed at the bottom of the positioning block 304.

[0026] In this embodiment, as Figure 1As shown, multiple anti-slip pads are evenly installed on the outside of the handheld part 1, and the anti-slip pads are all ring-shaped silicone sleeves with anti-slip texture on the outer surface.

[0027] In this embodiment, as Figure 2 and Figure 3 As shown, the extension handle 3 is slidably connected to the inside of the extension groove 202, and multiple locking grooves 301 are evenly embedded in the top of the extension handle 3, and the locking screw 203 and the locking grooves 301 form a threaded connection structure.

[0028] In this embodiment, as Figure 3 and Figure 4 As shown, the top inner wall of the limiting groove 204 is embedded with multiple circular groove-shaped positioning grooves 205, and the positioning block 304 is a circular block structure. The pressing block 305 is slidably connected to the inside of the limiting groove 204, and the positioning block 304 and the embedded groove 302 form a sliding connection structure, and the positioning block 304 and the positioning groove 205 form an insertion connection structure.

[0029] In this embodiment, as Figure 1 and Figure 5 As shown, the blade part 4 includes a main blade 401, and a main cutting edge 402 is installed at the bottom of the main blade 401. Scale strips 403 are installed on both sides of the connection between the main cutting edge 402 and the bottom of the main blade 401.

[0030] In this embodiment, as Figure 1 and Figure 5 As shown, the main blade 401 has multiple bone needle grooves 404 running through its interior, and a secondary blade 405 is mounted on the top of the main blade 401, and the secondary blade 405 has a serrated blade structure.

[0031] In this embodiment, as Figure 1 and Figure 6 As shown, the blade sleeve 5 is provided with a transparent dustproof plate on the outside, and a positive magnetic block 501 is installed at one end of the blade sleeve 5, and the positive magnetic block 501 and the negative magnetic block 201 form a close connection structure.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the scalpel used for spinal surgery operates as follows:

[0033] First, hold the handle 1 with the anti-slip pad on the outside of the handle 1, remove the positive magnetic block 501 that is attracted to the negative magnetic block 201 at one end of the extended handle 2, and then remove the blade sleeve 5 from the blade part 4.

[0034] Then press the pressing block 305 in the bottom limiting groove 204 of the extension handle 2, so that the pressing block 305 pushes the positioning block 304 out of the positioning groove 205 into the inner groove 302 at the bottom of the extension handle 3. At the same time, rotate the locking screw 203 at the top of the extension handle 2, so that the locking screw 203 disengages from the locking groove 301 at the top of the extension handle 3, and the extension handle 3 can be pulled out from the extension groove 202 to adjust the length of the scalpel.

[0035] Next, when the extension handle 3 is adjusted to the appropriate length, release the pressing block 305. Under the action of the reset damping spring 303 in the embedded groove 302, push the positioning block 304 to engage with the positioning groove 205 at the corresponding position. At the same time, rotate the locking screw 203 at the top of the extension handle 2 until it is locked with the locking groove 301 at the corresponding position. This completes the extension of the scalpel to meet the needs of spinal surgery.

[0036] Finally, the main blade 402 at the bottom of the main blade 401 at the blade section 4, in conjunction with the scale strip 403, is used to remove tumors in the spinal region. At the same time, the serrated secondary blade 405 at the top of the main blade 401 is used to clean bone spurs, and the bone needle groove 404, in conjunction with the bone needle, is used to correct the spine, thereby improving the practicality of the scalpel.
