Needle holder with tail end capable of flexibly rotating at multiple angles for laparoscope

Abstract

The invention relates to the technical field of biomedical engineering, and discloses a needle holder with the tail end capable of flexibly rotating at multiple angles for a laparoscope, the needle holder comprises a cavity tube, the needle holder device comprises a motor, a rotating shaft, a connecting rod, an annular block and a moving device, the motor is fixedly connected to the axial inner side of the left portion of the cavity tube through a rectangular block, and the rotating shaft is fixedly connected to the rotating shaft. The left side of the motor is in transmission connection with a rotating shaft, the left side of the rotating shaft is rotationally connected with a connecting rod, and the left side of the connecting rod is rotationally connected with an annular block. According to the needle holder with the tail end capable of flexibly rotating at multiple angles for the laparoscope, through the matching effect of a second handle, a first handle, a first spring, a conduction rod, a connecting block, a moving frame, a sliding block, a rail block, a fixed rod, an annular block, a connecting rod and a needle holder head, the purpose of adjusting the transverse angle of the needle holder head is achieved; therefore, the problems of difficulty in surgical operation and poor surgical effect are solved.

Description

technical field [0001] The invention relates to the technical field of biomedical engineering, in particular to a needle holder with multi-angle flexible rotation at the end of a laparoscope. Background technique [0002] Laparoscopic surgery has been widely accepted in many fields of pediatric surgery, but due to the limited freedom of forceps, laparoscopic surgery is more technically and ergonomically difficult than open surgery. The application purpose of the needle holder is to achieve reliable intraluminal suture in a small space. With the continuous advancement of science and technology, the development of needle holders tends to be more and more diversified. [0003] The existing needle holders for the end of laparoscope mainly have the following technical defects: First, the angle of the needle holder at the end of the existing ordinary laparoscope cannot be adjusted, which leads to the fixed suture angle. The narrow operation space makes the operation difficult for...

Problems solved by technology

[0003]The existing needle holders for the end of laparoscope mainly have the following technical defects: First, the angle of the needle holder at the end of the conventional common laparoscope cannot be adjusted , which in turn leads to the fixation of the surgical suture angle. Because the patient’s laparoscopic operation space is narrow, the operation is difficult for many laparoscopic operations, resulting in difficult operation and poor surgical effect; The setting uses the handle to adjust the angle of the needle holder at the end of the laparoscope, but the handle is completely controlled and fixed by the medical staff, which leads to the fact that the adjusted angle of the needle holder cannot be effectively and stably fixed, thus making it difficult to adjust the angle of the needle holder question
