Description

Jaw puncture baffle is printed to 3D

Technical Field

The utility model relates to the technical field of medical instruments for biopsy puncture, in particular to a 3D printing jaw puncture guide plate.

Background

The jawbone is located in the middle and lower third of the face and is an important tissue organ for maintaining facial form and function. Jaw diseases are common multiple diseases in the oral area, which seriously affect the maxillofacial appearance and function. The jawbone diseases are hidden in early stage, and the patients often have advanced pathological changes when seeing a doctor due to dysfunction, so that the overall prognosis is poor. At present, the preoperative diagnosis can only rely on pathological biopsy, but the pathological biopsy is blind, in the puncture process, whether an important planing structure can be damaged cannot be guaranteed, secondly, the puncture direction also needs to be judged by experienced medical staff, the direction has a certain influence on the accuracy of diagnosis, the jawbone position is deeper, the tissue incision biopsy has great damage to local, and the tissue healing after the biopsy is poor. These causes cause difficulties in the preoperative diagnosis of jaw diseases.

In recent years, most of puncture technologies are puncture under the guidance of CT, CT can go deep into the focus of a patient, present the size, structure and the like of the focus, improve the accuracy and the diagnosis rate of puncture to a certain extent, and avoid injuring important anatomical tissues. However, the CT guided puncture operation is complex, difficult to succeed at a time, and patients and doctors need to bear a certain radiation amount.

The utility model discloses a 3D printing technology-based oral and maxillofacial deep tumor puncture biopsy guide plate, which comprises a mask type guide plate substrate matched with the tissue shape of the maxillofacial outer surface, wherein the mask comprises an outer ear fixing hole, an upper tooth occlusion tooth socket and a clamping position corresponding to outer nasal bone, and a puncture needle channel is arranged on the mask substrate.

Therefore, how to realize the preoperative puncture diagnosis by using the medical instrument with simple and flexible structure and no inaccuracy becomes the technical problem to be solved.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art, and provides the 3D printing jaw puncture guide plate which is simple and flexible in structure, saves the cost of manpower and material resources and improves the success rate of puncture.

The aim of the utility model can be achieved by the following technical scheme:

the utility model provides a 3D prints jaw puncture baffle, includes bite plate and needle way part that adopts 3D printer to make, needle way part is equipped with at least three needle way that uses when puncture biopsy, bite plate and needle way part meet through an access mouth in the middle of the connecting portion.

As a preferred embodiment, the connecting portion is located on the bite plate.

As a preferred technical scheme, the connecting part presents a protruding semicircular structure.

As a preferable technical scheme, the connection mode of the biting plate and the needle track part is that the needle track part is vertically and upwards inserted into an access opening of the connection part of the biting plate.

As an optimal technical scheme, the biting plate is a biting plate which is personalized through different upper and lower teeth biting structures of patients.

As a preferable technical scheme, the needle track part is perpendicular to the connecting part at one end of the needle track part, which is required to be inserted into the access port.

Compared with the prior art, the utility model has the following beneficial effects:

1. compared with the mask type design in the prior art, the utility model simplifies the structural design, only comprises two parts, has short manufacturing period and saves the cost of manpower and material resources under the condition of keeping the advantages of avoiding important anatomical tissues and improving the success rate of puncture of the needle track part in the prior art.

2. Compared with the prior art, the utility model has higher flexibility, and because the biting plate and the needle track are in a separated design and are connected through the connecting port positioned on the biting plate, even if the tumor size of a patient changes, the position of the puncture needle track is influenced, only the needle track part can be reprinted, and the resource waste is avoided to a certain extent.

Fig. 1 is a schematic structural view of the present utility model.

Detailed Description

The utility model will now be described in detail with reference to the drawings and specific examples. The present embodiment is implemented on the premise of the technical solution of the present utility model, and a detailed implementation manner and a specific operation process are given, but the protection scope of the present utility model is not limited to the following examples.

As shown in fig. 1, a 3D printing jawbone puncture guide plate comprises a biting plate 1 and a needle track part 2, wherein the biting plate 1 and the needle track part 2 are connected through an access port 4 of a connecting part 3, one end of the needle track part 2 is perpendicular to the access port 4 of the connecting part, one end with a needle track is provided with a certain angle, and each part is of a structure manufactured by a 3D printer.

The connecting portion 3 is located on the bite plate 1. The connecting portion 3 presents a protruding semicircular structure. The connecting mode of the biting plate 1 and the needle track part 2 is that the needle track part 2 is vertically upwards inserted into the access opening 4 of the connecting part 3 of the biting plate 1. The bite plate 1 is a bite plate which is personalized by different upper and lower teeth bite structures of patients.

The manufacturing steps of the utility model include:

1. using CT image of a patient to lead in medical modeling software to build a three-dimensional digital model, and firstly designing a bite plate 1 according to the upper and lower tooth structures of the patient;

2. marking the position of the tumor, simulating the needle path position of the inserted puncture needle, determining the optimal needle path direction, avoiding important anatomical structures and reaching the focus;

3. designing a bite plate 1 and a needle track part 2 for comprehensive adjustment, and designing a connecting part 3;

4. and importing the guide plate STL data generated by the design into a 3D printer to perform 3D printing.

When the guide plate is used for puncture biopsy, the guide plate is sterilized before operation, and when a patient completely bites the bite plate 1, whether the needle track position is compounded with the original design is determined again, and then the puncture biopsy operation can be performed through the needle track.

In summary, the utility model simplifies the structural design and only comprises two parts under the condition that the advantages of avoiding important anatomical tissues and improving the success rate of puncture of the needle track part in the prior art are maintained, the manufacturing period is short, the cost of manpower and material resources is saved, and the utility model has higher flexibility degree.

The foregoing describes in detail preferred embodiments of the present utility model. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the utility model by one of ordinary skill in the art without undue burden. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
