Problems solved by technology

[0003] At present, anesthesia and puncture are performed manually based on the doctor’s clinical experience. During the whole process, the doctor controls the needle angle, needle speed and needle depth according to the hand feeling, blood return, and predicted depth; not only is it blind , Time-consuming and labor-intensive, labor-intensive, and there is a risk of easy nerve damage; medical staff have a heavy psychological burden
In addition, since the puncture needle needs to pierce tissue layers of different structures, it is difficult to control the strength and speed of the needle insertion by manual puncture, so it is easy to increase the pain of the patient

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] Such as figure 1 Shown: the housing 4 is fixed with a control module 6 electrically connected to the stepper motor 3, the rotating shaft of the stepper motor 3 is a lead screw nut 7, and a hollow tubular lead screw 8 cooperating with it is arranged in the lead screw nut; The tail end of the needle 2 (that is, the right end in the figure) protrudes into the housing 4 and is threadedly connected with the lead screw. The lighting system is composed of an optical fiber tube 10 whose front end passes through the lead screw 8 and extends into the puncture needle 2 , and an illuminating lamp (not shown) connected to the tail end of the optical fiber tube. The visual system consists of a transmission fiber 9 whose front end extends into the fiber tube 10, a display 1 connected to the end of the transmission fiber through a photoelectric convers...

Abstract

The invention discloses a visual anesthesia puncture automatic inserting device, and aims to provide a visual anesthesia puncture device capable of controlling needle inserting depth and speed. The device comprises a puncture needle, an illumination system and a visual system. A stepper motor (3) and a control module (6) are fixed in a casing (4), the stepper motor (3) is connected with a hollow tubular screw (8) through a screw nut, and the puncture needle (2) is connected to the lead screw. The illumination system is formed by a fiber tube (10) extending into the puncture needle (2) and an illumination lamp connected to the fiber tube. The visual system is formed by a transmission fiber (9) extending into the fiber tube (10), a display (1) connected to the transmission fiber by a photoelectric conversion device and a camera (11) coated at the front end of the transmission fiber (9). The automatic inserting device can intuitively reflect the position of the puncture needle in the human tissues, has the advantages of being simple and convenient to operate, high in efficiency, accurate in puncture position and good in safety, and is the visual anesthesia puncture device.

Description

technical field [0001] The invention relates to a puncture automatic propulsion device, in particular to a visible anesthesia puncture automatic propulsion device which can control the depth and speed of needle insertion; it belongs to medical equipment. Background technique [0002] Anesthesia puncture is an important part of surgery. The depth and accuracy of puncture are directly related to the anesthesia effect of the surgical patient, and have a major impact on whether the entire operation process can be carried out smoothly and postoperative rehabilitation. Due to the different surgical sites, the complexity of the disease, and the physical condition of the patient, doctors are required to have rich clinical experience and skilled operating skills. [0003] At present, anesthesia and puncture are performed manually based on the doctor’s clinical experience. During the whole process, the doctor controls the needle angle, needle speed and needle depth according to the ha...
