Illuminating scalpel applied to outdoor operation

Technical field of an illuminated scalpel used for outdoor surgery

[0001] The present invention belongs to the technical field of scalpels, and specifically relates to an illuminated scalpel for outdoor surgery.

Background technique

[0002] Scalpels used by surgeons in hospitals are divided into blades and handles. The blade is disposable, the handle is not. Other instruments are not disposable, but they are autoclaved each time they are used. The so-called sterilization is to kill all microorganisms. So as long as the disinfection is strict, there is no need to worry about this problem.

[0003] Existing scalpels are divided into: 1. Bow-handling style: The bow-handling style is the most commonly used way of holding a knife, with a wide range of movements and flexibility, and the force involves the entire upper limb, mainly on the wrist. Used for long skin incisions and incisions of the anterior sheath of rectus abdominis. 2. Pen-holding style: The pen-holding style is gentle and flexible, and the operation is flexible and accurate. It is easy to control the movement of the knife. The movement and strength are mainly in the fingers. It is used for short incisions and delicate operations, such as dissecting blood vessels, nerves, and cutting the peritoneum. 3. Holding type: The holding type holds the handle with all hands, and the thumb and index finger tightly pinch the notch of the handle. This method is more stable in controlling the knife. The main activity point of the operation is the shoulder joint. It is used for incisions with a wide range of incisions, thick tissues, and greater force, such as amputations, tendon incisions, and long skin incisions. 4. Back-pick style: It is a conversion form of holding the back-pick pen style. The blade is lifted upwards to avoid damage to deep tissues. When operating, pierce it first, with the moving point on the finger. It is used to cut abscesses, blood vessels, trachea, common bile duct or ureter and other hollow organs, cut off the clamped tissue or expand the skin incision, etc. 5. Shiatsu type: Shiatsu type is heavy, the index finger presses the front end of the handle, and the back half is hidden in the hand. This method is slightly inflexible to control the knife. It is mainly suitable for skin tissues that are difficult to cut.

[0004] Existing outdoor illuminated scalpels have some shortcomings in the use process. For example, Chinese patent application number CN201620041534.3, application date 2016.01.16, is named as a universal illuminator used for field surgery The invention patent of the scalpel adds functions such as lighting and a rotatable blade, but the function is still relatively simple. Because it is used outdoors, the scalpel does not have a good sterilization equipment, and the sanitary conditions are poor.
