Problems solved by technology

[0007] In order to solve the problem of positioning deviation in the existing template puncture technology before and during the puncture, this application provides a non-coplanar puncture template based on multi-point positioning, which is used to solve the existing puncture template due to the use of the puncture site. Problems with unavoidable skew errors for localization of muscle and / or fat cortex
Furthermore, since the patient is undergoing tumor sampling, it is impossible to achieve exactly the same body position before specifying the puncture plan and when performing the puncture. Therefore, it is unrealistic to use the positioning between the device and the patient's body, which will introduce greater errors; Therefore, the positioning of the puncture template and the human body itself is an unchangeable factor. It is precisely because of this that the existing positioning errors or deflection problems cannot be effectively resolved.

Embodiment 1

[0042] In order to more clearly explain the structure and working principle of the present invention, further description will be made below in conjunction with the accompanying drawings of the description, specifically in conjunction with the accompanying drawings of the description. Figure 1-Figure 5 shown, and as image 3 The shown non-coplanar puncture template based on multi-point positioning includes a puncture template body 1, and the puncture template body 1 is also fixedly connected with a plurality of puncture template bodies extending outward along the periphery of the puncture template body 1 to form contact with the surface of the bony parts of the human body. Fitting positioning template. The specific shape of the positioning template can be set according to the actual puncture site. The principle of setting is to collect the bony point positioning points in the axial direction of the human spine, and the thinner the soft tissue coverage is, the better. There a...

Embodiment 2

[0060] On the basis of Embodiment 1, in order to take into account the production and processing of the preoperative puncture template body 1, and at the same time satisfy the unaffected puncture operation during the operation and provide excellent opening performance, this embodiment further combines the attached figure 1 - As shown in convex 5, the puncture template body 1 and any one of the positioning templates are fixedly connected by positioning rods 6, and the positioning rods 6 are formed by integrally formed horizontal sections 61 arranged horizontally, which are respectively arranged on the The first vertical section 62 and the second vertical section 63 at two ends of the horizontal section 61 are formed; the free end of the first vertical section 62 is fixed on the upper surface of the positioning template, and the free end of the second vertical section 63 is fixed on the upper surface of the puncture template body 1 .

Abstract

The present application discloses a non-coplanar puncture template based on multi-point positioning, which includes a puncture template body, and the puncture template body is also fixedly connected with a plurality of puncture templates extending outward along the periphery of the puncture template body to form a bond with the surface of the human bony part. positioning template. The present invention can simultaneously reduce or even eliminate the problem of position error or deflection caused by the difference between the preoperative tumor sampling and the intraoperative puncture position of the patient by adding a plurality of positioning templates with the position of the patient's bony point; at the same time, it also It can reduce or even eliminate the problem of puncture deflection caused by soft tissue deformation between the patient's tumor body and the body surface, including muscle tissue and fat tissue.

Description

technical field [0001] The present invention relates to the technical field of medical surgical instruments or auxiliary devices, in particular to the technical field of precise puncture auxiliary devices involved in brachytherapy technology, and in particular to a non-coplanar puncture template based on multi-point positioning. Background technique [0002] Although there are many effective treatment methods for tumors in the existing medical technology, due to the early onset of tumors, there are often no symptoms, which makes early detection and early treatment difficult. Therefore, for example, the method of achieving recovery through surgical resection is not suitable for large Some tumor patients; the remaining treatment methods are usually radiotherapy and chemotherapy and targeted therapy, among which targeted therapy is the most effective of all tumor treatments, but based on its strict requirements on the tumor condition and the cost of targeted drugs Also makes mo...
