Problems solved by technology

[0003] The existing patent No. CN109171896B proposes a scalpel, which has the function of adjusting the angle of the blade of the scalpel, but the device has a limited load capacity on the blade, and requires a wide variety of specifications and types of blades during the operation, so multiple spare blades are required. The above-mentioned device loaded with different blades has the problem of reduced efficiency in preparation, access and cleaning
[0004] The existing patent number CN105640618B proposes an anti-shake scalpel, which can make the knife head resist slight hand shaking, thereby improving the quality of surgery, but it has the problem that the blade size cannot be observed intuitively during use, resulting in mishandling. The risk of surgery being compromised by the need for blades

Embodiment 1

[0042] Example 1: Please refer to Figure 1-8 , the present invention proposes a surgical scalpel, comprising a handle 1, a connecting plate 16, a clamping block 17 and a knife barrel 21, the handle 1 is a cylinder hollowed out in the center, and the inner wall of the handle 1 is fixedly connected with a cover block A3, The center of the cover block A3 is hollowed out and connected with a rotating rod 4. The rotating rod 4 is T-shaped and the front end is attached to the front of the handle 1. The rear end of the rotating rod 4 is fixedly connected with a spur gear A5, and the back of the spur gear A5 Five spherical protrusions 6 are arranged at equal intervals, and the outer wall of the rear end of the handle 1 is fixedly connected with the connection plate 16. The connection plate 16 is an elliptical cylinder and the back side is hollowed out. 21 is a cylinder hollowed out on the inside and the back side. The cutter head 22 is sleeved in the cutter barrel 21. The cutter head...

Embodiment 2

[0046] Example 2: Please refer to Figure 9 , on the basis of Embodiment 1, the front wall of the rotating rod 4 is equidistantly provided with five cutouts 42, the cutouts 42 are semi-cylindrical, the outer wall of the handle 1 is fixedly connected to the limit plate 44, and the limit plate 44 is L-shaped. , the outer wall of the front end of the limit plate 44 corresponds to the cut groove 42 and is sleeved with a sleeve block B46. The sleeve block B46 is a hollow rectangular body, and the bottom end of the sleeve block B46 is fixedly connected with a cutout 43. Correspondingly, the top surface of the cutting block 43 is fixedly connected with a spring D45, and the top of the spring D45 is fixedly connected with the limit plate 44. When rotating the rotating rod 4, when the rotation angle of the rotating rod 4 is not 1 / 5 of the circumference , the spring D45 drives the cutting block 43 to press down through the rebound, thereby squeezing the rotating rod 4 to rotate until it...

Embodiment 3

[0047] Example 3: Please refer to Figure 10-12 , on the basis of the second embodiment, two scraper rings 47 are sleeved on the outer wall of the knife cylinder 21, the scraper rings 47 are in the form of semi-circular rings and bonded to the outer wall of the knife cylinder 21, and the scraper rings 47 are made of a magnetic material and bonded to each other. The scraper ring 47 has a triangular cross-section, and the joint of the scraper ring 47 corresponds to the hollowed out part of the outer wall of the cutter barrel 21. A chute 48 is provided on the top surface of the connection plate 16, and a spring E49 is fixedly connected to both sides of the chute 48. Two springs E49 The unfixed ends are respectively fixedly connected with two scraper rings 47 . The position corresponding to the knife cylinder 21 on the top surface of the connection plate 16 is provided with a scale. When the blade stretches out, the two scraper rings 47 will be driven to separate from each other. ...

Abstract

The invention relates to the technical field of medical treatment, and discloses a surgical scalpel. The surgical scalpel comprises a grab handle, a connecting disc, a clamping block and a scalpel cylinder; the inner wall of the grab handle is fixedly connected with a sleeve block A; the centre of the sleeve block A is hollow and sleeved with a rotating rod; the outer wall of the rear end of the grab handle is fixedly connected with the connecting disc; the connecting disc is an oval cylinder; furthermore, the back side surface of the connecting disc is hollow; the back side surface of the connecting disc is fixedly connected with the scalpel cylinder; a cutter head is in sleeved connection in the scalpel cylinder; the cutter head is a round body; furthermore, the right side surface of thecutter head is fixedly connected with a sleeve; the right end of the sleeve penetrates through the right side surface of the scalpel cylinder; the outer wall, located outside the scalpel cylinder, ofthe sleeve is fixedly connected with a straight gear C; the inner wall of the right side of the sleeve is fixedly connected with a spring C; the left end of the spring C is fixedly connected with anair guide cylinder; and an air bag is fixedly connected to the left side surface of the air guide cylinder. Due to arrangement of the scalpel cylinder, five blades are contained at the same time, so that the preparation time of tools before an operation is easily shortened; furthermore, the blades can be quickly switched during operation; the time required for taking scalpels with the blades of different sizes during the operation is shortened; and the operation efficiency is easily improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a surgical scalpel. Background technique [0002] A scalpel refers to a special knife composed of a blade and a handle for cutting human or animal tissue, and is an indispensable tool in the surgical process. [0003] The existing patent No. CN109171896B proposes a scalpel, which has the function of adjusting the angle of the blade of the scalpel, but the device has a limited load capacity on the blade, and requires a wide variety of specifications and types of blades during the operation, so multiple spare blades are required. The above-mentioned device loaded with different blades suffers from reduced efficiency in preparation, access and cleaning. [0004] The existing patent number CN105640618B proposes an anti-shake scalpel, which can make the knife head resist slight hand shaking, thereby improving the quality of surgery, but it has the problem that the blade size cannot ...
