Description
Technical Field
The utility model belongs to the technical field of the medical appliances technique and specifically relates to a scalpel with adjustable length.
Background
A scalpel is one of the most common tools in medical surgery at present, and doctors need to use the scalpel to cut open tissues of patients and to cut off focus parts. The traditional scalpel is simple in structure and single in function, the depth of an incision cannot be controlled accurately, organs or subcutaneous tissues can be damaged, and the length of the scalpel cannot be controlled accurately. In the utility model patent of china that publication number is CN206687753U, a neurosurgery is with scalpel with adjustable length is published, adjusts the length that the cutter body exposes through sliding tray and slider, and the doctor of being convenient for controls the scalpel more conveniently in the operation, can save operating time, improves the success rate of operation. However, the device still has certain defects, in particular, because the sliding block is arranged at one side of the knife handle, if the friction force of the anti-sliding block is insufficient, the anti-sliding block can easily slide, so that the stability of the device is reduced, and in addition, although the length of the scalpel can be adjusted, the exposed length of the scalpel body cannot be accurately controlled.
Disclosure of Invention
The utility model aims at overcoming above-mentioned technical shortcoming and providing a scalpel with adjustable length, can locking device through the knob of screwing, make the blade expose the part and be difficult for rocking easily, be equipped with the scale mark in addition, can show accurately that the blade exposes the specific length of part, can also show the degree of depth that the blade got into skin tissue.
The utility model provides a technical scheme that technical problem adopted does: a scalpel with adjustable length comprises a scalpel handle, a blade, a knob, an LED lamp and scale marks, wherein a scalpel handle cavity is formed in the scalpel handle, the blade is embedded into the scalpel handle cavity, the exposed part of the blade can be freely adjusted, teeth are arranged on the upper surface of the blade, the knob is arranged at the front end of the scalpel handle cavity and is in threaded connection with the scalpel handle, the part, located in the scalpel handle cavity, of the knob is connected with a locking block through a bearing, a fixing block matched with the teeth on the blade is arranged on the locking block, and the fixing block on the locking block is embedded into the teeth of the blade by screwing the knob; the blade is provided with scale marks, the scale marks take the blade tip as a starting point and reach the tail end of the blade, the scale marks are used for accurately displaying the specific length of the blade exposed out of the knife handle and providing reference for a doctor to implement a specific operation, and meanwhile, the scale marks can also display the depth of the blade entering skin tissues, so that the doctor can conveniently control the force; the utility model discloses a scalpel handle, including handle of a knife, LED lamp, switch, battery case, LED lamp and switch electric connection, the handle of a knife tail is equipped with the battery case, the LED lamp sets up in the handle of a knife front end, is equipped with the switch on the LED lamp, battery case, LED lamp and switch electric connection, the LED lamp is towards the blade knife tip, can provide auxiliary light source.
Furthermore, the knife handle is provided with anti-slip lines to increase the friction force when the doctor holds the knife.
Furthermore, the blood groove is formed in the blade, so that blood can flow out conveniently during operation, and blood at the incision can be prevented from being blocked due to the fact that the blade fills the incision, so that thrombus can be prevented from being formed by coagulation or the blood can flow into the body.
The utility model discloses the beneficial effect who has is: the utility model has the advantages of reasonable structural design, the blade can freely slide in the cavity of the handle of a knife, thereby the length of the blade exposed out of the handle of a knife is adjusted, the knob is screwed, the fixed block on the locking block is embedded into the teeth of the blade, the length of the device is locked at the moment, the device is not easy to shake easily, and meanwhile, the knob is loosened, and the blade can also be directly dismantled for replacing and disinfecting; the LED lamp can provide an auxiliary light source for operation; the blood groove is convenient for the outflow of blood during operation, and prevents the blood from being coagulated to form thrombus or flowing into the body due to the blood jam at the incision caused by the filling of the incision by the blade; the scale marks can accurately display the specific length of the blade exposed out of the knife handle, reference is provided for the implementation of the specific operation of a doctor, and meanwhile, the depth of the blade entering skin tissues can be displayed through the scale marks, so that the doctor can conveniently control the force.
