CT-guided Puncture Positioning Fixer
[0001] The invention relates to the technical field of medical puncture and the technical
field of parts manufacturing, particularly to the technical field of high-efficiency puncture
assistance.
[0002] The existing medical CT positioning puncture device consists of a puncture needle
guiding device, a fixing device and a positioning device. At present, most of the CT
puncture positioning technologies on the market have the problems of long positioning
time, low positioning accuracy and poor reliability. Thus not only bringing certain pain to
patients, but also increasing the diagnosis time of doctors. Moreover, the design of guide
rail in CT puncture positioning device is very important for the efficiency of puncture and
the determination of the best path.
[0003] Through the movement of each component, the complicated three-dimensional
position can be located. The whole device consists of a circular four-legged bracket
structure, a transparent chute, an arc chute, a vertical dovetail groove and a puncture
needle guide groove. Through the mutual movement of these components, it helps the
puncture needle guide groove to point to the lesion rapidly, improves the puncture
accuracy, reduces the risk of puncture complications and saves the puncture positioning
time. Based on the safety and reliability of the positioning device, the selection of
materials for the composition structure needs to meet the working requirements of
medical consumables. The cooperation between the structures also needs to be tight and
reliable. The positioning device can adjust the puncture at any angle. Therefore improving the cooperation degree of the composition structure. The puncture accuracy will also be greatly improved. In addition, in order to make the positioning device more stable in the pathological part of the patient on the basis of flexible combination with skin, bandage is used to fix it on the body, and the base should also be made of flexible material. The puncture positioning device has characteristics such as accuracy, high efficiency, safety and reliability. It is also small, simple, convenient to operate and easy to popularize and use.
[0004] The purpose of the present invention is to provide an accurate, efficient, safe and
reliable medical CT positioning puncture structure, so as to effectively solve the problems
of complicated puncture technology and long diagnosis time of doctors at present.
[0005] The invention provides a medical CT positioning puncture structure. The structure
comprises a disc base structure for assisting in fixing the whole device. The structure
selects a suitable material as a four-legged base to flexibly adhere to the skin of a patient.
The selected materials, preparation process, hardness and processing precision must meet
the requirements to support the circular motion of the transparent chute.
[0006] The upper end of the transparent chute structure is open. The structure is also used
to support the planar movement of the arc chute in the horizontal direction. The material
is plastic, and the application process is molding.
[0007] The arc chute is used to support the 1/4 arc movement of the puncture needle
guide groove. Moreover, the arc chute structure is fixed between the transparent chute
and the vertical dovetail groove. The material is polyetheretherketone (PEEK) plastic.
The processing technology is transfer molding.
[0008] Furthermore, the vertical dovetail groove is used for supporting the movement of
the puncture needle guide groove in the Z direction. The vertical dovetail groove has
wear resistance to stabilize the puncture needle guide groove. The material is also
polyetheretherketone (PEEK).
[0009] Furthermore, the puncture needle guide groove is a device for restricting the
movement of the puncture needle. Moreover, it directly points to the needling direction of
the puncture needle. The material is polycarbonate (PC) plastic.
[0010] Furthermore, the function of bandage is to fix the whole positioning device on the
body part of the patient, so as to prevent the reverse torque from being generated if the
puncture needle is too long. Therefore making the diagnosis and treatment under puncture
safer and more reliable.
Furthermore, most of the whole structural materials of the device are medical plastic
materials. The processing technologies are thermoplastic and transfer molding.
[0011] The invention has the beneficial effects that: by using the puncture positioning and
fixing device, improving the puncture success rate, reducing puncture complications and
improving the diagnosis and treatment efficiency of puncture lesions.
[0012] The puncture positioning and fixing structure comprises a disc base structure, a
transparent chute, an arc chute and a vertical dovetail groove structure. The disc base
structure and bandage are combined to flexibly attach the puncture device to the patient's
skin and stabilize it in the approximate area of the patient's lesion sampling. The circular
movement of the transparent chute and the planar movement of the arc chute can realize
further adjustment to determine the best puncture path. Finally, the arc movement of the
vertical dovetail groove and the vertical movement of the puncture needle guide groove on the dovetail groove can achieve further fine adjustment. Thus determining the accurate and best path for the needling of the puncture needle.
[0013] Compared with the existing puncture positioning devices in the market, this
device greatly saves the preparation work before puncture and greatly improves the
puncture efficiency.
[0014] In order to explain the specific embodiments of the present invention more
clearly, the drawings that need to be used are briefly introduced in the description of the
specific embodiments or the prior art below. The following drawings are some
embodiments of the present invention. Other reasonable drawings can be obtained
according to these drawings for other researchers in the field.

[0017] The technical scheme of the present invention will be described clearly and
completely with reference to the drawings, and the described embodiments are part of the
embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by other researchers in the field without making creative designs belong to the protection scope of the present invention.
[0018] As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the invention provides a
medical CT puncture positioning device structure. The structure comprises a circular
four-legged bracket structure, a transparent chute structure, an arc chute structure, a
vertical dovetail groove structure and a puncture needle guide groove structure.
[0019] When installing the components, the arc chute is installed between the transparent
chute and the vertical dovetail groove, and the puncture needle guide groove is installed
on the vertical dovetail groove. The clearance fit should meet the mutual normal
movement between the components.
[0020] When designing the size of the puncture positioning device, the diameter of the
disc base is 40mm, the length of the bandage is 85mm, and the diameter of the puncture
needle guide groove is 4 mm. The design of the device's length and diameter is to make
the puncture positioning device more convenient to use and improve its use and sampling
efficiency. The device is easy to disassemble and has high reuse rate.
[0021] Remarks: the above embodiments are only used to illustrate the technical scheme
of the present invention, but not to limit it. Researchers can modify the parameters in the
above embodiments according to the needs of monomer size and its arrangement.
