Problems solved by technology

[0004] The current scalpel does not have a limit structure to control the depth of the blade. The depth of the doctor's knife depends on the doctor's experience and technique. It is difficult to accurately control the depth, and often the blade is too shallow or too deep.
During the operation, if the blade is too shallow, the cutting purpose or cutting effect will not be achieved, and the knife needs to be re-entered and re-cut, which will increase unnecessary pain to the patient; while the blade is too deep, it will cause harm to the patient, and also increase unnecessary pain to the patient. pain
Therefore, the current scalpel still has the defect that it is not safe and reliable enough, which is also a technical problem that has been expected to be solved all the time.

Embodiment 1

[0025] Such as figure 1 , figure 2 and image 3 As shown, this scalpel with limit protection includes a handle 1, a blade 2, a base plate 3, a support 4, a rotating shaft 5 and two lifting mechanisms 6, and the edge of the base plate 3 is provided with an arc-shaped bevel 7, and the blade includes Knife back 201 and blade 202; Blade 2 is installed on the lower end of handle of a knife 1; Support 4 is installed on the base plate 3, and the upper end of support 4 is provided with notch 8, and notch 8 is provided with outward and downward slope 9; The upper end of the handle 1 is rotatably installed in the notch 8 through the rotating shaft 5; the blade 2 extends below the bottom plate 3 from the edge of the bottom plate 3; two lifting mechanisms 6 are installed on the bottom plate 3, and the power output ends of the two lifting mechanisms 6 Connect with the middle and lower part of handle 1.

[0026] The lifting mechanism 6 includes a screw rod 601, a sleeve 602 and a positi...

Embodiment 2

[0029] In the case that other parts are the same as in Embodiment 1, the difference is that the lifting mechanism 6' includes a rack 601', a gear 602', a rack guide sleeve 603' and a rocker 604', and the upper part of the rack 601' is provided with There is a position marking line 605'; the lower end of the gear guide sleeve 603' is fixedly installed on the base plate 3; the gear 602' is rotatably installed in the gear guide sleeve 603'; one end of the rocker 604' is connected to the tooth surface of the gear 602'; The lower part of the rack 602' is in the rack guide sleeve 603', the rack 601' meshes with the gear 602';

[0030] By shaking the rocker 604', the gear 602' is rotated, and the gear 602' drives the rack 601' to move up and down in the rack guide sleeve 603', thereby driving the middle and lower part of the handle 1 to rise and fall, that is, the handle 1 is adjusted. The inclination of the blade 202 is adjusted, thereby adjusting the size of the blade 202 exposed b...

Abstract

The invention relates to a scalpel with a limiting protection function. The scalpel comprises a scalpel handle, a blade, a bottom plate, a support, a rotating shaft and at least one lifting mechanism. The blade is mounted at the lower end of the scalpel handle, the support is mounted on the bottom plate, and a notch is formed in the upper end of the support; the upper end of the scalpel handle is rotatably mounted in the notch through the rotating shaft, the blade extends to the position below the bottom plate from the edge of the bottom plate, the lifting mechanism is mounted on the bottom plate, and a power output end of the lifting mechanism is connected with the middle-lower portion of the scalpel handle. The bottom plate, the support and the lifting mechanism are provided, the bottom plate is used as a supporting face and a reference plane of the scalpel, and the lifting mechanism is used for adjusting the exposing size of the blade below the bottom plate, so that the scalpel feeding depth is limited, the condition that the scalpel is fed to shallow or too deep is avoided, an operation is more precise, pain of patients is reduced, and the scalpel is safer and more reliable; in addition, the lifting mechanism is used for adjusting the exposing size of the blade anytime, and the scalpel feeding depth is adjusted anytime according to requirements of operations.

Description

technical field [0001] The invention relates to a surgical knife, in particular to a surgical knife with limit protection. Background technique [0002] Scalpel is a surgical instrument commonly used in surgery and internal medicine. Any operation must use a scalpel. It can be seen that a scalpel is a necessary condition for surgery and is quite important. [0003] Due to the relatively single function of the scalpel, there has been no major reform in structure. Present scalpel generally comprises handle of a knife and blade, and blade is arranged on an end of handle of a knife, and during operation, doctor holds handle of a knife with hand, cuts with blade the periphery of diseased part on the patient's body. Removing the tissue of the diseased part, or cutting out some tissue samples for testing and analysis, so as to finally achieve the purpose of recovering the patient, is also the most effective and direct way of treating diseases. [0004] The current scalpel does no...
