Description

Scalpel suitable for intramedullary fixing system

Technical Field

The utility model belongs to the field of scalpels, in particular to a novel scalpel suitable for an intramedullary fixing system.

Background

The existing knife handle with the blade is only used for incising soft tissues such as skin, subcutaneous tissues, fascia and the like in the conventional operation, and the skin, subcutaneous tissues and fascia cannot be incised through the positioning hole of a surgical instrument (intramedullary fixing system). In the operation, instruments need to be removed and an operation incision needs to be made, so that the operation steps are increased, the fracture displacement needs to be reset, the operation time is increased, and the medical risk is increased. And the incision accuracy can be deviated, thereby increasing the operation difficulty.

Disclosure of Invention

The utility model aims at providing a simple structure, convenient to use need not put aside surgical instruments (intramedullary fixing system) in the operation, and fine slender neck can operate the accurate soft tissue such as incision skin, subcutaneous, manadesma through the locating hole of apparatus, makes things convenient for the scalpel of doctor's operation.

The purpose of the utility model is realized like this:

a scalpel suitable for an intramedullary fixing system comprises a fixing support and a scalpel, wherein the fixing support is L-shaped and comprises a short rod and a long rod, the upper end part of the short rod is provided with an intramedullary needle fixing part, and the long rod is provided with a locking needle positioning hole; the scalpel includes scalpel handle and demountable installation at the scalpel blade of scalpel handle front end, scalpel handle includes that the hand is held between the fingers the portion and elongated neck, and scalpel blade installs at elongated neck front end, the hand is held between the fingers the portion and is the platykurtic, and elongated neck length > twice of hand holding between the fingers portion length, the minimum width of lock needle locating hole is greater than the maximum width of elongated neck cross-section.

The elongated neck is elliptical with a major axis of 0.7cm and a minor axis of 0.3 cm.

The length of the slender neck part is 15cm, and the length of the hand-pinching part is 6 cm.

The length and the width of the cross section of the hand-held part are 2cm and 03 cm.

Resistance-increasing grains are formed on two side faces of the hand-pinching part.

The front end of the slender neck part is formed with a groove for hand pinching.

The surgical blade is a No. 23 surgical blade.

Compared with the prior art, the utility model outstanding and profitable technological effect is:

1. through the arrangement of the slender neck, a surgical instrument (an intramedullary fixing system) does not need to be removed in the operation, the slender handle body can be used for performing the operation through the positioning hole of the instrument, so that the soft tissues such as skin, subcutaneous tissue, fascia and the like can be accurately incised, the operation of a doctor is facilitated, the incision accuracy is improved, and the operation is more convenient and accurate;

2. surgical instruments do not need to be removed in the operation, so that the operation procedures and operations are reduced, and the operation is easier and simpler;

3. because the instrument does not need to be removed in the operation, the fracture displacement caused by the movement of the surgical instrument is avoided, the resetting is needed again, the operation difficulty is reduced, the operation time is saved, and the operation risk is reduced.

4. Resistance increasing lines are formed on two side faces of the hand-pinching part, so that the friction force between the fingers of the doctor and the scalpel is increased, and the operation is performed more stably in the operation process.

5. Because the scalpel needs to pass through the positioning hole, and the fixing support and the incision are at a certain distance, the scalpel is relatively long, so that the scalpel is not well controlled in the operation process, the front end part of the slender neck is formed with a groove for holding the hand, one hand holds the hand holding part as a fulcrum, and the other hand holds the groove to move, so that the scalpel can be stably controlled.
