Problems solved by technology

[0005] In order to solve many problems caused by inaccurate puncture due to the lack of accurate auxiliary devices in the existing puncture, severe cases may lead to serious consequences such as pneumothorax, and even critical illness and death
In order to reduce or even eliminate many problems caused by low puncture accuracy and avoid secondary harm to patients, this application provides an auxiliary guidance and positioning device for CT puncture, which is used to realize puncture guidance and positioning, specifically the image obtained through CT scanning The determined precise puncture needle track can be guided by the accurate instructions of this application, so as to avoid the problem of skewed puncture caused by the doctor not knowing the puncture angle when performing the puncture operation

Embodiment 1

[0043] This embodiment aims to describe the process, principle and related structure of auxiliary guided puncture in combination with the existing CT machine. Specifically, this embodiment provides a positioning device for auxiliary guided puncture of CT, such as Figure 1-Figure 4 As shown, it is composed of a control mechanism and an actuator. The actuator includes a base 1, and a support frame 2 installed on the base 1 for supporting the positioning device. The support frame 2 has two rotatably connected with the positioning device. End, any end of the support frame 2 is provided with a locking mechanism 4 for limiting the deflection angle of the positioning device; A guide device 8 for indicating the space puncture angle is installed, and the guide device 8 includes a deflection drive mechanism sliding along the first guide rail 7, a first translation mechanism 87 and a second translation mechanism 88 installed vertically; On the second translation mechanism 88, a guide me...

Embodiment 2

[0055] As one of the refinement schemes of the present application, this embodiment is further refined on the basis of embodiment 1, such as Figure 4-Figure 6 As shown, the deflection drive mechanism includes a guide frame 82 as the installation and support body, the second servo motor 81 is detachably and fixedly installed on the guide frame 82, connected with the second servo motor 81 and positioned on the first guide rail 7 drives the driving wheel 83 connected to it, and a plurality of groups of stabilizing wheels 84 that are rotatably mounted on the guide frame 82 and located on the inner and outer sides of the first guide rail 7 respectively. When it is necessary to deflect in the radial plane, that is, in the plane of CT tomography, the second servo motor 81 drives the drive wheel 83 that is centrifugally and fixedly connected to it to rotate. Since the guide frame 82 is slidingly connected with the first guide rail 7, the Driven by the second servo motor 81, the entir...

Embodiment 3

[0057] This embodiment is an optimized structure proposed on the basis of Embodiment 2 for the situation where parallel puncture is required in the plane where the patient's scanning slice is located, specifically as Image 6 As shown, the first translation mechanism 87 includes a second guide rail 85 detachably and fixedly installed on the guide frame 82, a slide seat 872 that slides and is clamped on the second guide rail 85, and is respectively arranged on the The two ends of the second guide rail 85 are driven and connected to the third servo motor 86 and the follower 873 through a belt 871 ; the sliding seat 872 is detachably and fixedly connected to the belt 871 . When adjustment is required, the first translation mechanism 87 executes the parameters that need to be translated through the measurement of the CT machine, and translates the indication of the guide mechanism 89 from the ray pointing to the coaxial center of the CT machine and the auxiliary guiding and positio...

Abstract

The present application discloses a positioning device for CT puncture auxiliary guidance, which is composed of a control mechanism and an actuator. The actuator includes a base, a support frame, and any end of the support frame is provided with a locking mechanism; the positioning device It includes a first guide rail arranged in an arc, on which a guide device for indicating different puncture angles in the same plane is slidably installed, and the guide device includes a deflection drive mechanism that slides along the first rail, vertically A first translation mechanism and a second translation mechanism are installed; the second translation mechanism is slidably installed with a guide mechanism that uses visible laser space to indicate puncture. The present invention can be used in conjunction with existing detection equipment, such as CT, MRI, and PET-CT. The puncture needle path information determined by the image can be obtained through the imaging equipment, and the present invention can be used to accurately position and indicate in space to assist doctors. The operation avoids misalignment and error caused by experience or bare-handed puncture.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a surgical medical instrument device, in particular to a CT puncture auxiliary guiding and positioning device. Background technique [0002] Needle biopsy is the main method for obtaining histopathological diagnosis of bone and soft tissue tumors. Bone and soft tissue tumors are diseases that seriously endanger human health and life. In recent years, the incidence rate has gradually increased, and the age of onset has gradually decreased. Early detection, correct diagnosis, and timely treatment have an important impact on prognosis. With the continuous improvement of examination methods and methods, the correct rate of diagnosis has gradually increased, but there are still a large part of tumors that do not have typical imaging features, making diagnosis difficult. A correct diagnosis requires a combination of clinical, imaging, and pathological factors. Among them,...
