The blade head 130 includes a blade 1303, a blade holder 1302, and a blade connector 1301, the blade 1303 and the blade connector 1301 being disposed on the blade holder 1302, the blade holder 1302 being connected to the handle bar 110 by the blade connector 1301.

The external weight 120 comprises a weight 1201 and a weight connector 1202, and the weight connector 1202 is arranged on the weight 1201;

the blade mounting end of the holding rod 110 is provided with a blade 1303 mounting head matched with the blade connector 1301, the weight mounting end of the holding rod 110 is provided with a weight 1201 mounting head matched with the weight connector 1202, the blade 1303 mounting head is connected with the blade connector 1301, and the weight 1201 mounting head is connected with the weight connector 1202.

In this embodiment, the surgical knife 100 can be replaced with different blade heads 130 according to the surgical scene. The surgical knife 100 is arranged by the holding rod 110, so that a conventional doctor and a common person can conveniently hold the surgical knife 100 like a pen, and the cutting accuracy of the blade 1303 corresponding to the surgical knife 100, relative to the human body or animal body tissue, of the conventional doctor and the common person is improved;

generally, both conventional doctors and ordinary people can pick up an object and keep a relatively static state, but the degree of pressing force of a tool on the object cannot be grasped well; if the quality of the tool is changed, when the pressing force of the tool on the object needs to be controlled, the stability of the tool only needs to be controlled, and the pressing force of the tool relative to the object can be realized by pressing the object by means of the self weight of the tool; by arranging the external weight 120, the surgical knife 100 can replace the external weight 120 with different qualities in a specific surgical scene, so that the cutting strength of the blade 1303 corresponding to the surgical knife 100 relative to the human body or animal body tissue can be improved for conventional doctors and ordinary people.

According to the technical scheme provided by the embodiment, the external weight 120 is arranged on the surgical knife 100 to adjust the weight of the surgical knife 100, so that the cutting force of a knife edge on human or animal body tissues grasped by a conventional doctor or a common person is improved; by providing the grip lever 110, a general doctor or a general person can grasp the cutting strength and the cutting accuracy of the blade to the human or animal tissue by pinching the grip lever 110. Therefore, the problem that the cutting force and the cutting accuracy of the knife edge on the human body or the animal body tissue are difficult to master by conventional doctors or ordinary people in the prior art is solved.

Optionally, the holding rod 110 is provided with an anti-slip structure 115 near the blade mounting end.

In specific implementation, the anti-slip structure 115 is disposed on the holding rod 110 near the blade mounting end, which is beneficial to increase the friction between the palm of the general doctor and the ordinary person and the surgical knife 100, so as to prevent the knife from slipping and causing secondary injury.

Optionally, the anti-slip structure 115 is formed by forming a circular protrusion 1102 on the outer surface of the handle bar 110.

During specific implementation, the anti-slip structure 115 is arranged to be the annular protrusion 1102, so that the holding rod 110 can be integrally arranged, peripheral objects are not required to be sleeved outside the holding rod 110, the process difficulty is not increased, and in order to improve the comfort degree of the contact between the annular protrusion 1102 and a palm, the outer surface of the annular protrusion 1102 can be subjected to frosting treatment.

Alternatively, the holding bar 110 is made of solid stainless steel.

The holding rod 110 made of stainless steel is a solid structure, so that the holding rod 110 has a certain mass to improve the feeling of holding the surgical knife 100 in the palm.

Optionally, the blade connector 1301 is a first protrusion 13011 provided with an external thread;

the blade 1303 mounts the head to a first recess 1103 provided with an internal thread;

Optionally, the weight connector 1202 is a second protrusion 12021 provided with an external thread;

the weight 1201 is provided with a second recess 1101 provided with an internal thread;

the external weight 120 and the holding rod 110 are connected with the second recess 1101 through the second protrusion 12021.

Optionally, the blade edge of the blade 1303 is disposed at an edge of a side of the blade 1303 remote from the blade mounting end.

As shown in fig. 5-7, in practical implementation, since the surgical knife 100 is held by the pen holder, when the surgical knife 100 is used, the surgical knife is inclined to some extent, and when the surgical knife 100 is used, the blade is disposed on one side of the blade 1303 that is inclined to the horizontal plane or one side that is away from the inclined defense line, which is beneficial to the operation habit of the operator and convenient for observation in the operating room.

Optionally, the insert 1303 is a cambered insert 1303.

In specific implementation, the blades 1303 can be set to be different shapes according to the human or animal body tissues to be cut, and the blades 1303 are cambered blades, which is beneficial to increasing the contact range of the blade tips to the human or animal body tissues.

Optionally, the insert 1303 includes a connection surface, a knife edge remote from the connection surface, a first side surface, a second side surface, a first end surface, and a second end surface;

the insert 1303 is connected to the insert holder 1302 via a connecting surface, the first side surface and the second side surface are respectively connected to the connecting surface and the long side of the blade surface, and the first end surface and the second end surface are respectively connected to the connecting surface and the short side of the blade surface;

When the surgical knife 100 is used, the holding rod 110 forms a certain inclination angle with respect to the horizontal plane, and the side length of the first end surface is greater than or equal to that of the second end surface, which is favorable for the blade edge of the blade 1303 to be parallel to the horizontal plane when the holding rod 110 is inclined.

Optionally, the blade 1303 is a cambered blade 1303.

In short, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
