Examples

In order to facilitate the positioning operation and simplify the operation flow of the prior disinfection and percutaneous puncture positioning, the embodiment provides a simple structure on the basis of the embodiment 1.

When the marking assembly is inserted and no downward pressure is applied, the insertion end of the marking assembly can be suspended in the opening 11, and the end face of the insertion end is not contacted with the skin of the patient; when a downward pressure is applied, the positioning press assembly 12 is able to deform in the direction of the force and the stamping surface of the insertion end of the marker assembly is able to contact the patient's skin and leave a mark.

As shown in fig. 5, the development pattern 22 is applied to the development surface of the marking assembly (i.e., the outer end surface of the marking assembly) for easy identification during operation. The position and pattern distribution rule of the development pattern 22 are the same as those of embodiment 1, and the number of marking components to be inserted into the through hole 121 in this embodiment can be determined according to the size of the lesion position or the operation requirement.

The marking assembly may be, but is not limited to, a rubber head dropper 32, and the present embodiment is described by way of example with respect to the rubber head dropper 32. The development pattern 22 is pre-coated on the development surface of the rubber head dropper 32 (i.e. the rubber head of the rubber head dropper 32), and the rubber head dropper 32 is internally sucked with a non-percutaneous puncture type staining liquid, such as a purple liquid medicine, which can quickly leave marks on the skin surface of a patient.

If the same mark as the corresponding developed pattern 22 is to be left on the skin, the hole 11 may be formed in a hole shape corresponding to the developed pattern 22.

The operation process comprises the following steps:

step 1: allowing the patient to lie on the image examination bed;

Step 2: estimating the approximate number and positions required for the marking assembly, inserting the marking assembly into the corresponding through hole 12;

step 3: attaching the developing patch body 1 to the skin at the pathological change position of the spine of a patient, enabling the longitudinal line 212 to be overlapped with the spinous process of the spine, moving and determining the position of the developing patch body 1 through an imaging device, and enabling the transverse developing pattern 222 to be overlapped with the positions of the corresponding pedicle, the articular process and the transverse process respectively;

step 4: the marking position to be made is determined by combining the imaging equipment, the positioning pressing component 12 is deformed by pressing down the marking component, the printing surface of the marking component (namely the opening end of the rubber head dropper 32) is contacted with the skin of a patient, and meanwhile, the developing surface of the rubber head dropper 32 is extruded, so that the liquid in the rubber head dropper 32 is contacted with the skin of the patient, and the purpose of making marks by transfer printing is realized.

Examples

Embodiment 3 differs from embodiment 2 only in the structure of the marking assembly.

As shown in fig. 8 to 10, the marking assembly may be a transfer head 33, and this embodiment is exemplified by the transfer head 33. The outer end of the transfer head 33 is a developing surface, on which the developing pattern 22 is coated, and the insertion end is a printing surface for transfer. The printing surface may be provided with the same pattern as or different from the developed pattern 22, and may be selected as required. When the transfer head 33 is inserted into the through hole 121, in order to enhance the holding force of the through hole 121 on the transfer head 33, a reverse stop ring is preferably provided on the inner wall of the aperture at the lower part of the through hole 121.

Steps 1 to 3 of the procedure are identical to example 2, except for step 4, wherein:

Step 4: the position to be marked is determined by combining the imaging device, the positioning pressing assembly 11 is deformed by pressing down the marking assembly, the printing surface of the transfer head 33 is contacted with the skin of the patient, the food-grade pigment pre-coated on the printing surface of the transfer head 33 is transferred onto the skin, and the mark is left.

Examples

Because the developing patch body 1 used in the above embodiment is made of a silica gel material, when the developing patch body 1 is repeatedly used for a long time or the tensile force is too large, the developing patch body 1 can generate certain deformation, and the original size is changed, so that the accuracy of later positioning is affected. In order to solve this problem, the present embodiment optimizes the structure of the development patch body 1 on the basis of the foregoing embodiment.

The middle layer of the developing patch body 1 is embedded with a plurality of buried wires 4, the whole buried wires 4 are in a fish-tail shape, and the buried wires 4 are positioned on the periphery of the opening 11.

As shown in fig. 11, in the first embedding method, the buried lines 4 arranged horizontally are parallel to the horizontal lines 211 in the developing grid 21, and the buried lines 4 arranged vertically are located on both sides of the vertical lines 212 in the developing grid 21.

As shown in fig. 12, in the second embedding method, the buried lines 4 arranged vertically are located on both sides of the vertical lines 212 in the developing grid 21, and the buried lines 4 on both sides are not perpendicular to the vertical lines 212 and are parallel to each group of the lateral developing patterns 222.

In the use, because buried line 4 of latticed has been buried in advance, make developing paste body 1 can reset fast after deformation takes place, can effectively prevent developing paste body 1 size deformation's emergence to the accuracy of location has been ensured.

Examples

When the whole developing patch body 1 is attached to the skin of a patient, the friction force can be increased, but since the back contour of the human body is not a smooth curved surface when the patient is prone, the attaching surface of the developing patch body 1 cannot be ensured to be completely attached to the skin. For this purpose, in example 5, the structure of the developing patch body 1 was optimized based on example 4, and the cutting position of the cutting opening 5 and the buried line 4 were complementary to each other and did not interfere with each other.

As shown in fig. 13, the first embedding method in example 4 is provided with a cutout 5: the developing patch body 1 is provided with at least one group of cutting openings 5 symmetrically arranged along the length direction of the developing patch body 1, and the cutting openings 5 are cut in a direction perpendicular to the longitudinal line 212. When the developing patch body 1 is attached to the skin through the cutting opening 5, the curvature of the back of a patient is more suitable.

As shown in fig. 14, the second embedding method in example 4 is provided with a cutout 5: the developing patch body 1 is provided with the shearing openings 5 which are symmetrically arranged along the length direction of the developing patch body 1 and are at least one group, and the shearing openings 5 are sheared in the direction parallel to the buried line.

In the foregoing, the present utility model is merely preferred embodiments, which are based on different implementations of the overall concept of the utility model, and the protection scope of the utility model is not limited thereto, and any changes or substitutions easily come within the technical scope of the present utility model as those skilled in the art should not fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
