A double-ended scalpel with a protective sheath

Abstract

The invention relates to a double-headed scalpel with protective covers. The double-headed scalpel comprises a handle, a first blade, a second blade and two protective covers, wherein the first blade and the second blade are arranged at the two ends of the handle respectively, and each protective cover comprises a pin rod, a first protective piece, a second protective piece, a first elastic piece and a second elastic piece. Pin holes are formed in the scalpel back, and the pin rods are positioned in the pin holes and are in tight contact and match with the pin holes. The inner ends of the first elastic pieces and the inner ends of the second elastic pieces are connected with the upper portions of the pin rods respectively, the upper portions of the first protective pieces and the upper portions of the second protective pieces are connected with the outer ends of the first elastic pieces and the outer ends of the second elastic pieces respectively, and the lower ends of the first protective pieces and the lower ends of the second protective pieces are provided with blunt portions facing cutting edges. By means of the two blades, demands for cutting various tissues are met, and delay of operations is avoided. The protective covers protect the cutting edges, so that the safety of the double-headed cutting edges is ensured. The blunt portions at the lower ends of the first protective pieces and the lower ends of the second protective pieces form blocking surfaces to limit the feeding depth of the scalpel, so that the operations are more accurate, patients' pain is alleviated, and the double-headed scalpel is safer and more reliable.

Description

technical field [0001] The invention relates to a surgical knife, in particular to a double-headed surgical knife with a protective cover. Background technique [0002] Scalpel is a surgical instrument commonly used in surgery and internal medicine. Any operation must use a scalpel. It can be seen that a scalpel is a necessary condition for surgery and is quite important. [0003] Due to the relatively single function of the scalpel, there has been no major reform in structure. Present scalpel generally comprises handle of a knife and blade, and blade is arranged on an end of handle of a knife, and during operation, doctor holds handle of a knife with hand, cuts with blade the periphery of diseased part on the patient's body. Removing the tissue of the diseased part, or cutting out some tissue samples for testing and analysis, so as to finally achieve the purpose of recovering the patient, is also the most effective and direct way of treating diseases.

AI Technical Summary

Problems solved by technology

[0005] However, during clinical operations, patients may have multiple diseases, and sometimes a lesion involves multiple tissues. In this case, it is necessary to be equipped with a variety of scalpels of different specifications for the cutting of different tissues.

[0006] However, often due to underestimation of the condition, or sometimes negligence, the types of scalpels equipped are not complete. In this way, when a certain tissue is to be cut, it is found that no suitable scalpel can be found, and it is necessary to ask the nurse to re-equip it urgently. However, it still takes a certain amount of time, causing delays in surgery and adding unnecessary pain to patients

[0007] In addition, the current scalpel does not have a limit structure to control the depth of the blade. The depth of the knife used by the doctor depends on the doctor's experience and technique. It is difficult to accurately control the depth, and the blade is often too shallow or too deep.

During the operation, if the blade is too shallow, the cutting purpose or cutting effect will not be achieved, and the knife needs to be re-entered and re-cut, which will increase unnecessary pain to the patient; while the blade is too deep, it will cause harm to the patient, and also increase unnecessary pain to the patient. pain

Therefore, the current scalpel still has the defect that it is not safe and reliable enough, which is also a technical problem that has been expected to be solved all the time.
