Description

Operating handle and surgical instrument Technical Field The invention relates to the technical field of medical instruments, in particular to an operating handle and a surgical instrument. Background In laparoscopic surgical procedures, surgical clamping devices are often used that access the abdomen through small diameter tubes or cannulas inserted through small incisions in the skin. During surgery, medical personnel perform the action of an implement inserted into a patient by manipulating a surgical gripping instrument outside the patient. In the field of medical equipment, the types of operating handles are various, but at least one operating member is generally arranged on the operating handle to control the operation of the surgical instrument, and when the operating member on the existing operating handle is arranged, a great deal of research is generally conducted on how to improve the convenience and labor-saving effect of operation. However, in the operation process, the medical staff needs to hold the operating handle all the time and keep a certain posture, and in the process, the operating member on the operating handle in the related art is easily touched by mistake in the use process, so that the precision of the surgical instrument is affected. It is therefore necessary to design an operating handle which is both convenient to operate and which can avoid erroneous touching of the operating member during use. Disclosure of Invention The present invention aims to solve one of the technical problems in the related art to a certain extent. Therefore, the invention provides the operating handle and the surgical instrument, which can improve the operating comfort and accuracy of a user. In order to achieve the above object, a first aspect of the present invention discloses an operating handle comprising a housing and a first operating member mounted to the housing, the housing comprising a main body portion and a grip portion, a window being formed in the main body portion, at least a part of the first operating member being exposed to the window, the main body portion being provided with an inwardly recessed finger groove on a rear side of the first operating member, the first operating member having a plurality of ridges and recesses distributed at intervals in a circumferential direction, the ridges being not higher than an outer surface of the main body portion, the recesses being lower than the ridges and not lower than a surface of the finger groove. According to the technical scheme, the window and the first operating piece exposed out of the window are arranged on the main body portion, the first operating piece is convenient to operate, operation is further facilitated, the first operating piece is easier to contact and apply force to the first operating piece by the fingers of an operator through the position of the finger groove, the finger groove is arranged on the rear side of the first operating piece, when the first operating piece needs to be operated, the fingers can be naturally supported in the finger groove to operate, the first operating piece is easier to operate accurately, and due to the structure that the outer surface of the first operating piece is not higher than the outer surface of the main body portion, the first operating piece is not easy to be mistakenly touched by the movement of the fingers when operation is not needed, and operation accuracy is improved. Further, the first operating member is formed in a tapered structure having a rear end diameter larger than a front end diameter, and/or a central angle of the concave portion is larger than a central angle of the ridge portion. The larger concave part is convenient for the finger to apply force to the first operation piece and can accommodate the thickness of the finger, and the conical structure is suitable for the natural extension of the finger, so that the operation is convenient. Further, at least two concave parts and at least two ridge parts are exposed out of the window, and/or the number of the window and the number of the finger grooves are two, and the window and the finger grooves are symmetrically distributed on two side surfaces of the main body part respectively. The window and the finger grooves are symmetrically distributed, so that the operating requirements of different operating habits of the left hand and the right hand of an operator can be met, and the left hand and the right hand are smooth to operate. Further, the width of the finger groove is equal to or smaller than the width of the window, and/or the finger groove is bent and extended toward the grip portion along the rear end of the body portion in the axial direction. In the width supporting range of the finger groove, the fingers can touch the first operation piece, so that the phenomenon that the fingers apply force to step on the air is avoided. Under the condition that the finger groove is bent and extended, when being favor
