Problems solved by technology

[0014] Aiming at the objective problems in the field that the accuracy of the above-mentioned surgery cannot be guaranteed, causing additional trauma to the human body, and limited scope of application, the present invention provides a percutaneous implant that can be used on any part of the human body, especially on bone parts with a body position fixation device. The new preparation method of the navigation guide, and the percutaneous navigation guide prepared by this method, can be used in orthopedics, neurosurgery and / or oncology and other related percutaneous puncture operations to reach the target, which can reduce X-ray radiation. Without increasing the trauma to the human body, the application of the 3D printed percutaneous needle / nail insertion navigation guide ensures that the operation can be completed quickly and accurately

Embodiment 1

[0058] Embodiment 1, the preparation method of the percutaneous navigation guide plate using the body membrane to fix the body position

[0059] This embodiment provides a method for preparing a percutaneous navigation guide for any part of the human body that requires surgery, such as Figure 1 to Figure 3 shown, including the following steps:

[0060] (1) Use a body position fixing device to fix the part 1` of the human body that needs surgery, and the said part needs to be operated corresponding to the internal lesion and / or the target; The body position fixing device described in the examples is specifically a body membrane (the body membrane is not shown in the figure). The body film refers to a thermoplastic film that can be softened at 65-70°C and can be shaped and fixed at room temperature; the specific operation is: treat at 65-70°C for 1-3 minutes to soften the body film, Covering and wrapping on the surface of the skin 11' corresponding to the site to be operated ...

Embodiment 2

[0070] Embodiment 2, the preparation method of the percutaneous navigation guide combined with the body position fixation pad

[0071] This embodiment further provides a method for preparing a percutaneous navigation guide for performing leg orthopedic surgery, such as Figure 4 and Figure 5 shown, including the following steps:

[0072] Steps (1) and (2) as described in Example 1, first perform body position fixation and marker setting, the two are not in any order, but in order to ensure that the body position fixation corresponds to the site where the marker is located. The skin has the best fixed posture and surgical coordination angle, and it is preferable to perform the posture fixation step first, such as Figure 4 As shown, the body position pad 5' is used to fix the part of the human body that requires surgery, so that the body position pad 5' forms a mold that matches the body position; On the skin surface corresponding to the surgical site, the percutaneous navi...

Embodiment 3

[0077] Embodiment 3, percutaneous navigation guide plate and surgical components according to the present invention

[0078] This embodiment provides a percutaneous navigation guide plate combined with a body position fixation device, which is characterized in that it includes a guide plate with at least one curved surface that fits with the skin surface of the human body to be operated on, and at least one positioning hole that penetrates the guide plate and at least one guide channel, the guide channel includes a channel part that penetrates the guide plate and a pipe channel part in the elongated hollow rib protruding from the opposite side of the curved surface; the positioning hole and the fixing The markers on the skin surface of the human body need to be operated are adapted in quantity, size and shape; the guide channel is in quantity, direction, angle and length with the part of the skin exposed by the needle and / or nail in the percutaneous operation , fit in shape an...

Abstract

The invention provides a preparation method for a percutaneous navigation guide board combined with a body position fixation device, pertaining to the field of medical instruments. The method comprises the following steps: (1) utilizing the body position fixation device; (2) fixing a marker to the skin surface corresponding to a required surgical spot of a human body, which is used for fixing the navigation guide board; (3) utilizing CT scanning technology to scan the required surgical spot to obtain spatial position data of a human body dissecting structure; (4) inputting CT scanning spatial position data into a computer and carrying out digital and three-dimensional reconstruction; (5) simulating operations in the virtual three-dimensional structure and virtually inserting needles / nails on the virtual skin surface where markers are located; (6) fitting the navigation guide board on the virtual skin surface, wherein the navigation guide board is closely attached to the skin surface and can be used for virtual needle / nail insertion adapted to the virtual markers and the navigation guide board has guide pipelines; (7) inputting data of the above virtual guide board into a 3D printer, wherein the 3D printer obtains the percutaneous needle / nail-inserting navigation guide board which can be used in combination with the body position fixation device.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a percutaneous navigation guide combined with a body position fixation device and a preparation method thereof. Background technique [0002] Considerable precision is required in modern medicine, especially in orthopedics, neurosurgery, oncology, and / or other departments (and other departments that require percutaneous localized procedures) for percutaneous access to target and localization procedures In order to ensure the accuracy and safety of the operation, it is usually necessary to go through repeated X-ray fluoroscopy before or during the puncture operation, or adjust the patient's position one by one, and according to the conventional experience in this field, a percutaneous puncture to the target point and focus location The required correction and adjustment requires an average of at least 10 times of fluoroscopy. That is to say, the doctor must support the p...
