As shown in fig. 2, the plurality of the snap grooves 121 includes a closed position snap groove 1211, a first extended position snap groove 1212, and a second extended position snap groove 1213, the first extended position snap groove 1212 being located between the closed position snap groove 1211 and the second extended position snap groove 1213; the second extended position catching groove 1213, the first extended position catching groove 1212, and the closed position catching groove 1211 are sequentially provided from the end of the mounting part 12 connected to the grip part 11 to the free end of the mounting part 12, and the closed position catching groove 1211, the first extended position catching groove 1212, and the second extended position catching groove 1213 are disposed parallel to each other. Further, the distance between the first protruding position fastening groove 1212 and the second protruding position fastening groove 1213 is 0.1 mm-1 mm, in a specific embodiment, the distance between the first protruding position fastening groove 1212 and the second protruding position fastening groove 1213 is 1mm, and the length of the scalpel 3 protruding out of the protective sleeve 2 is controllable, about 1mm, so that the maximum depth of the incision during the puncturing operation does not exceed 1mm, and arterial injury is not caused; the distance between the first extended position snap groove 1212 and the closed position snap groove 1211 is 1mm to 10mm, and in one embodiment, the distance between the first extended position snap groove 1212 and the closed position snap groove 1211 is 2mm.
As shown in fig. 5 and 6, in a state where the locking protrusion 22 is locked in the locking groove 1211 in the closed position, the surgical knife 3 is positioned in the protective sheath 2; as shown in fig. 7 and 8, the knife edge 31 of the scalpel 2 protrudes from the opening 21 of the protective case 2 in a state where the locking protrusion 22 is locked in the first protruding position locking groove 1212 or the second protruding position locking groove 1213.
Specifically, in the initial position, as shown in fig. 4 to 6, that is, in a state in which the scalpel 3 is positioned in the protective sheath 2, the locking protrusion 22 of the protective sheath 2 is locked in the locking groove 1211 of the closed position of the mounting portion 12, and at this time, the scalpel 3 is completely positioned in the hollow cavity 24 of the protective sheath 2, thereby preventing injury to the operator.
When the skin-breaking operation is required, as shown in fig. 7 and 8, the protective sleeve 2 is pushed toward the holding portion 11, and due to the external force, the one end 25 of the protective sleeve 2 is elastically deformed, in this embodiment, the plurality of fastening grooves 121 provided on the mounting portion 12 have the withdrawing side walls 1214, and the fastening protrusions 22 located on the protective sleeve 2 are provided with the inclined side walls 221, and when the fastening protrusions 22 are fastened in the fastening grooves 121, the withdrawing side walls 1214 are just matched with the inclined side walls 221, so that the advantage of the arrangement is that the fastening protrusions 22 can slide into or slide out of the fastening grooves 121. At this time, after the protective sheath 2 receives the thrust to the grip portion 11, the snap protrusion 22 therein will withdraw from the closed position snap groove 1211, and when the protective sheath 2 is pushed to the grip portion 11, the snap protrusion 22 will be snapped into the first protruding position snap groove 1212, and at this time, the knife tip 31 of the scalpel 3 will protrude from the opening 21 of the protective sheath 2, and at this time, the first position of the scalpel 3 is the first position, and in this position, the knife tip 31 of the scalpel 3 will protrude from the other end 26 of the protective sheath 2 by a length of about 1mm, and at this time, the operator can perform the skin breaking operation using this state.
The specific operation method is as follows: the arc surface at the other end 26 of the protective sleeve 2 is used as a fulcrum to prop against the skin of a patient, the scalpel 3 is rotated anticlockwise and upwards by taking the arc surface as a supporting point, at the moment, the knife tip 31 of the scalpel 3 cuts into the skin, when the skin is cut into, the scalpel 3 is pulled downwards to cut an incision of about 2 mm-3 mm of the skin, and at the moment, an interventional operation is performed by advancing the puncture needle. Because the depth and the length of the incision can be precisely controlled due to the supporting points when the skin-breaking operation is performed, important tissue injury is prevented, and the operation of operators is facilitated. Since the tip is only leaked out by about 1mm in this state, the maximum depth of the incision does not exceed 1mm when the puncture operation is performed, and thus the incision does not cut into the artery, and no damage to the important tissue is caused.
When the protective sleeve 2 is pushed in the direction of the holding part 11, one end 25 of the protective sleeve 2 is elastically deformed, the buckling protrusion 22 in the protective sleeve 2 is withdrawn from the buckling groove 1212 at the first extending position, and when the protective sleeve 2 is pushed in the direction of the holding part 11, the buckling protrusion 22 is buckled in the buckling groove 1213 at the second extending position, which is the second gear position of the scalpel 3, and in this position, the knife tip 31 of the scalpel 3 extends out of the other end 26 of the protective sleeve 2 by a length of about 2mm, which is shown in fig. 9 and 10, and the specific operation method is the same as that in the first gear, and the gear is mainly applied to a puncture point of an artery deeper under the skin, such as a femoral artery.
When the operator mismanipulates the protective sleeve 2 to the second gear position and needs to shift the second gear to the first gear position during shallower arterial puncture, the protective sleeve 2 can be pushed away from the holding portion 11, so that the fastening convex portion 22 of the protective sleeve 2 is matched with the fastening groove 1212 of the first extending position of the mounting portion 12, and the protective sleeve 2 is retracted to the first gear position. In this way, the protective sheath 2 can be switched between the snap grooves 121 of the handle 1, and at this time, an interventional operation of a puncture point with a shallow artery can be performed.
The invention discloses a skin breaking device, which solves the problem that the depth of a incision is poorly controlled and arterial injury is caused when an operator performs an operation. When the skin breaking operation is carried out, the skin breaking device can provide a supporting point for the scalpel, so that the suspension operation of the scalpel is avoided, the length of the scalpel tip extending out of the protective sleeve is effectively and accurately controlled, the purpose of accurately controlling the skin breaking depth is achieved, and the operation of operators is facilitated. The invention of the device is as follows: the skin breaking device can accurately control the skin cutting depth during the operation of an operator, prevent damage to important tissues such as nerve blood vessels and the like, and ensure the operation safety.
The invention discloses a skin breaking device, which is characterized in that a scalpel is arranged on a scalpel handle on the basis of an original common scalpel, a protective sleeve is sleeved on the scalpel, a buckling convex part and a plurality of buckling grooves which can be mutually matched with buckles are designed on the protective sleeve and the scalpel handle, and the skin breaking device is skillfully formed into a device capable of controlling the length of a scalpel tip exposing the protective sleeve when a doctor breaks skin with the scalpel, so that the depth of an operation incision is effectively controlled. The skin breaking device is characterized in that: when a doctor uses the skin breaking device to perform skin breaking operation, complications caused by too deep incisions do not need to be worried about, and the safety and convenience of operation are greatly improved.
