DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1: The utility model provides a novel surgical instrument, comprising a scalpel mechanism 1, including a scalpel assembly 11, a scraper assembly 12 movably mounted on one end of the scalpel assembly 11; a locking mechanism 2, including a locking rod assembly 21 for fixing the scraper assembly 12 on the scalpel assembly 11, and a driving assembly 22 for driving the locking rod assembly 21 to rotate; wherein the locking rod assembly 21 and the driving assembly 22 are both embedded in the interior of the scalpel assembly 11;

[0021] Among them, the scraper assembly 12 can be inserted into the scalpel assembly 11 to fix it, and the surgical staff can easily switch between the scalpel assembly 11 and the scraper assembly 12, thereby improving the surgical efficiency. The driving assembly 22 can be rotated by a tool such as a steel sheet to rotate the locking rod assembly 21. The rotation of the locking rod assembly 21 can lock the scraper assembly 12, thereby preventing the scraper assembly 12 and the scalpel assembly 11 from separating.

[0022] Specifically, the scalpel assembly 11 includes a gripping handle 111, one end of which is fixedly mounted with a blade head 112, and the other end of the gripping handle 111 is fixedly connected with an insertion handle 113; wherein, the gripping handle 111 and the blade head 112 are made of metal, and the blade head 112 has a certain curvature, so that the surgeon can conveniently cut and remove tissue during surgery.

[0023] Specifically, the scraper assembly 12 includes a connecting handle 121, one end of which is fixedly connected to a scraper body 122, and the other end of the connecting handle 121 is provided with a handle insertion groove 123; the handle 113 can be slidably embedded in the handle insertion groove 123; wherein, the handle 113 is preferably flat in shape, and the handle 113 is not easy to fall off after being immersed in the handle insertion groove 123, and the scraper body 122 has a certain inclination angle, so that it is convenient for surgical personnel to scrape tissue samples or scrape lesions.

[0024] As can be seen from the above, the holding handle 111 and the connecting handle 121 can be connected to each other by sliding the insertion handle 113 into the insertion handle groove 123. By holding the holding handle 111, it is convenient to switch between the blade head 112 and the scraper body 122, thereby improving the surgical efficiency. At the same time, the detachable scraper body 122 can also be convenient for the staff to replace it.

[0025] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that a long rod hole 114 connected to each other is further provided inside the holding handle 111 and the inserting handle 113, a gear groove 115 connected to the long rod hole 114 is provided on the upper side of the holding handle 111, and a threaded hole 124 is further provided on the connecting handle 121 at a position connected to the inserting handle groove 123.

[0026] Specifically, the locking rod assembly 21 includes a long rod 211, one end of which is fixedly connected to a threaded rod 212; the long rod 211 is movably embedded in the long rod hole 114, and the threaded rod 212 can be rotatably embedded in the threaded hole 124; wherein, the long rod 211 has a certain friction force when sliding horizontally in the long rod hole 114.

[0027] Specifically, the driving assembly 22 includes a driving gear 221, and a positioning sleeve 222 is fixedly connected to one side of the driving gear 221; the driving gear 221 is fixedly connected to the long rod 211 after the positioning sleeve 222 is penetrated by a screw; wherein, after the driving gear 221 in the gear groove 115 is penetrated by the screw, the side of the driving gear 221 still has a certain gap to accommodate a tool such as a steel sheet to enter, so that the driving gear 221 can rotate, and the end of the tool such as a steel sheet can be pressed against the tooth gap of the driving gear 221 to rotate the driving gear 221 to a certain angle, and the long rod 211 can be screwed into the threaded hole 124 through multiple rotations.

[0028] As can be seen from the above, the driving gear 221 is placed inside the gear groove 115, the long rod 211 is inserted into the long rod hole 114 and penetrates the driving gear 221, and the driving gear 221 and the long rod 211 are fixed to each other by the screw passing through the positioning sleeve 222 and then embedded in the long rod 211. When the driving gear 221 is rotated, the long rod 211 can be rotated, and the rotation of the long rod 211 can make the threaded rod 212 screwed into the threaded hole 124;

[0029] Specifically, by rotating the driving gear 221 with a tool such as a steel sheet, the positioning sleeve 222 can be rotated, and the rotation of the positioning sleeve 222 can rotate the long rod 211, and the rotation of the long rod 211 can cause the threaded rod 212 to be screwed into the threaded hole 124, thereby achieving a locking effect.

[0030] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
