Abstract
The utility model relates to an adjustable single-handle double-blade surgical knife which belongs to the technical field of surgical instruments and is composed of a handle, knife frames and blades, wherein, the knife frame is provided with a bidirectional knife trough which is matched with the blades. The front end of the handle is provided with a screw hole. A supporting rack A is fixed with a screw rod, and the supporting rack A at both ends of the screw rod is provided with a rectangular vacancy. One end of a supporting rack B and one end of a supporting rack C are respectively vertically fixed with a knife frame, and the other end of the supporting rack B and the other end of the supporting rack C are both provided with a rectangle vacancy. The three supporting racks are overlapped, the two knife frames respectively penetrate out of the rectangular vacancies at both ends of the supporting rack A, and the vacancies of the supporting rack B and the supporting rack C are overlapped. The screw rod penetrates out of the overlapped vacancies and is in screw-thread fit with the screw hole at the front end of the handle. The distance between the two blades of the surgical knife can be adjusted according to requirement.
Description
This utility model relates to this technical field of surgical instruments, particularly a kind of adjustable single-handle and double-blade scalpel.
Existing scalpel is all single handle hilted broadsword, has immutable shortcoming, when second operation, is difficult for the original cicatrix of parallel neat excision, wastes time and energy, for patients after surgery has increased infection chance; Postpone the healing of otch, influenced excision and some plastic operation of original cicatrix.
The purpose of this utility model is at above-mentioned the deficiencies in the prior art part, and a kind of adjustable single-handle and double-blade scalpel is provided, and this scalpel can be regulated the distance between double-pole as required, resection operation cicatrix that can be simply rapid, neat.
This utility model is achieved through the following technical solutions: this adjustable single-handle and double-blade scalpel, by handle of a knife, knife rest, blade is formed, two-way cutter groove is arranged on the knife rest, blade matches with the cutter groove, the front end of handle of a knife has a screw, be fixed with screw rod on the bracing frame A, one rectangle vacancy is all arranged on the bracing frame A at screw rod two ends, bracing frame B, each vertical fixing of an end of bracing frame C has a knife rest, the other end all has a rectangle vacancy, bracing frame A, bracing frame B, bracing frame C coincides, two knife rests pass from the rectangle vacancy at bracing frame A two ends respectively, bracing frame B, vacancy on the bracing frame C coincides, and screw rod passes in the vacancy of its coincidence, and screw rod becomes threaded engagement with the screw of handle of a knife front end.During use, rotatable handle of a knife, loosening screw is suitably regulated the distance between two knife rests as required, tightens handle of a knife then, and bracing frame A, bracing frame B, bracing frame C tightly are fixed together, and blade is matched with two-way cutter groove on the knife rest, can use.
This utility model compared with prior art has following advantage: this scalpel can be according to the distance between the width adjusting double-pole of cicatrix, accurately, parallel, neat, complete excision cicatrix, shorten operating time, be beneficial to operation back wound healing, infection of incisional wound, the poor problem of healing of avoiding the involutory difference of the uneven skin of two incisxal edges to cause.
Accompanying drawing 1 is a kind of sketch map of adjustable single-handle and double-blade scalpel; Accompanying drawing 2 is sketch maps of its handle of a knife; Accompanying drawing 3 is to be fixed with the bracing frame B of knife rest, the sketch map of bracing frame C on it; Accompanying drawing 4 is the sketch maps that are fixed with the bracing frame A of screw rod on it.
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail: the adjustable single-handle and double-blade scalpel of this kind, form by handle of a knife (6), knife rest (2), blade (1), two-way cutter groove is arranged on the knife rest (2), blade (1) matches with the cutter groove.The front end of handle of a knife (6) has a screw (7), bracing frame A(3) is fixed with screw rod (8) on, one rectangle vacancy (9) is all arranged the bracing frame A(3 at screw rod (8) two ends), bracing frame B(5), each vertical fixing of end bracing frame C(4) has a knife rest (2), the other end all has a rectangle vacancy (11), (10), bracing frame A(3), the vacancy bracing frame C(4 bracing frame B(5)) coincides, screw rod (8) passes in the vacancy of its coincidence, and screw rod (8) becomes threaded engagement with the screw (7) of handle of a knife (6) front end.Because of handle of a knife (6) is connected by screw with bracing frame, can separate at any time and connect, loosening screw can suitably be regulated distance between double-pole.
Screw rod (8) is positioned at bracing frame A(3) central authorities, bracing frame A(3) two the rectangle vacancies (9) on are positioned at the two ends central authorities of screw rod (8), knife rest (2) is at bracing frame B(5), bracing frame C(4) on the fixed position identical, bracing frame B(5), the rectangle vacancy (11) bracing frame C(4), (10) are all at the central part of the other end, can keep handle of a knife (6) to be in the centre position of double-pole (1) all the time, be beneficial to operation technique.
The adjustable single-handle and double-blade scalpel of this kind, during fabrication, the length that can make handle of a knife (6) is 12-15cm, point diameter 0.5cm, inner bolt hole diameter 0.25cm, handle of a knife (6) end thickness 0.15cm, bracing frame A(3) length is 5cm, thickness is 0.1cm, the high 0.8cm of middle screw rod (8), diameter 0.25cm, screw rod (8) is welded on bracing frame A(3) central authorities, the length of two ends central authorities' vacancies (9) bracing frame A(3) is 2cm, width is 0.4cm, and the height of knife rest (2) is 3cm, thickness 0.1cm, bracing frame B(5), the length of end central authorities vacancy bracing frame C(4) is 2.5cm, width is 0.4cm.Handle of a knife (6) and eclipsed bracing frame A(3), bracing frame B(5), bracing frame C(4) between with being threaded, can separate at any time and connect, the screw of loosening handle of a knife (6), distance between scalable double-pole (1), its adjustable extent is 0.5-4.5cm, can be used for position and some plastic operation such as face, chest, abdominal part, extremity.
