Description

Positioning operation guide plate

Technical Field

The utility model relates to the field of medical equipment, concretely relates to location operation baffle.

Background

With the development of minimally invasive surgery technology, a series of minimally invasive surgeries such as percutaneous transforaminal endoscopy and the like are increasingly mature at present, and can be applied to various lumbar diseases with indications. However, the endoscopic surgery requires body surface positioning as the first step, which is different from the traditional open surgery, and the minimally invasive surgery technology emphasizes small wound and accurate positioning, so that the difficulty of body surface positioning is greatly increased. At present, generally, a surgeon can place a guide needle on the body surface and realize body surface positioning by a method of C-arm machine positioning. Because the guide pin only exists in one plane each time C-arm video shooting is carried out, the method needs to repeatedly adjust the angle of the guide pin relative to the horizontal plane for many times in practical operation. And because of the range of the C-arm radiographs, identifying the specific segment of the lumbar spine requires physician discretion, and the C-arm radiographs are performed multiple times, eventually resulting in more radiation exposure to the patient and surgeon. On the other hand, if the C-arm machine needs to be positioned after the disinfection is finished and the position of the C-arm machine needs to be adjusted repeatedly for many times, the operation time can be prolonged, the chance of polluting the operation field is increased, and the risk of infection in the operation is enlarged, which is particularly prominent in low-age medical doctors with insufficient operation experience. The long learning curve of minimally invasive techniques dictates that low-grade physicians spend a significant amount of time trying and inflicting a significant amount of radiation damage during the process before becoming proficient in mastering the technique, and the patient may be less satisfied with it.

In recent years, regarding the rapid development of related technologies of guide plates for minimally invasive spine surgery, CN104958099B discloses a 3D printed transforaminal endoscope targeted puncture percutaneous surgery guide plate and a puncture method thereof, and relates to a 3D printed transforaminal endoscope targeted puncture percutaneous surgery guide plate which comprises a base and a guide plate body, wherein the guide plate body is supported by the base and positioned on a human body; the guide plate body is integrally formed by a positioning section connected with the base and a puncture guiding section for puncture positioning, a positioning groove in a guide plate positioning hole is just embedded with a base positioning bulge, and then puncture is carried out along a guide channel of a guide pipe obliquely arranged at the front end of the puncture guiding section. The advantages are that: the 3D printing percutaneous operation guide plate can avoid nerve and blood vessel damage in operation by planning a puncture path before operation and measuring the puncture depth, puncture along a guide hole in operation, can obviously shorten the operation time, reduce the perspective radiation amount, provide a prerequisite for the operations of reaming, placing a tube and performing under a microscope at the back and reduce the probability of nerve and blood vessel damage of a patient. However, the customized guide plate for 3D printing technology is a more expensive option for most patients in the current state, and although the intraoperative time can be shortened, the preparation time for the operation is increased, and finally the treatment cost is increased. And in the guide plate in-service use process that 3D printed, also need C arm machine auxiliary body surface location base to place the position, guarantee its accuracy of inserting needle position.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, 1 is a rectangular frame, 2 is a first wire, 3 is a second wire, 4 is a mark symbol, 5 is a positioning mark, and 6 is a fixing ring.

Detailed Description

The present invention will be described in detail with reference to the following detailed description of the preferred embodiments and accompanying drawings.

Referring to fig. 1, the positioning surgical guide plate comprises a rectangular frame 1, the length of the rectangular frame is 25-35 cm, the width of the rectangular frame is 12-20 cm, and specific size parameters can be reasonably selected according to the actual size of a patient.

The utility model discloses a medical instrument, including rectangular frame 1, be equipped with a first metal wire 2 parallel with rectangular frame 1 long limit and six second metal wires 3 parallel with rectangular frame 1 broadside in the

rectangular frame

1, 2 both ends of first metal wire are connected with 1 broadside middle part of rectangular frame respectively, regard as rectangular frame's axis promptly, and in concrete use, first metal wire 2 moves towards the effect of preliminary location as centering line and patient's backbone unanimously substantially.

The two ends of the second metal wire 3 are respectively connected with the long edges of the rectangular frame 1, and different mark symbols 4 are arranged at the end part of each second metal wire 3, so that the second metal wires 3 can be distinguished conveniently. The distance a between the adjacent second metal wires is equal, and the distance is 3-5 cm. The second metal wire 3 is provided with a plurality of positioning marks 5, the distance b between every two adjacent positioning marks is equal, and the distance is 2-3 cm.

The corners of the rectangular frame 1 are smooth transition curves, so that the gloves of a surgeon or the skin of a patient are prevented from being accidentally injured by sharp edges, and the safety of the positioning operation guide plate in the using process is ensured.

The middle part of the wide side of the rectangular frame 1 is provided with a fixing ring 6, on one hand, considering that a minimally invasive patient usually performs an operation in a waking state, the possibility of body movement is inevitable when the body surface is positioned, and the positioning is inaccurate, the fixing rings 6 at the upper end and the lower end can be fixed by adopting an adhesive tape to prevent the positioning operation guide plate from moving, and four sides can be fixed if necessary; on the other hand, the positioning operation guide plate is convenient to hang and place.

Rectangular frame, first wire and second wire are diameter 1.5mm stainless steel wire, and the cost is lower, and the thickness is equal to ke shi needle, so the total weight is also very light, is convenient for wash the recovery and recycle, and has certain structural strength, difficult deformation.

The location operation baffle have to the generally applicable characteristics of different patients, compare the individual customization baffle of current 3D printing, it can only be applied to appointed patient, and the patient if need perform the operation once more after certain year, then need carry out CT again and rebuild and print once more, the cost of expense is higher. Although this location operation baffle can not print the learning curve that the baffle shortened doctor by a wide margin as 3D, but can assist the faster C arm organism of carrying on of doctor of low-age capital to a certain extent and show the location, avoided producing the segmentation mistake simultaneously and think to no matter be the preparation material or make technology, the requirement all is less than 3D far away and prints the baffle, is fit for comparatively basic unit's hospital's expansion scope treatment work more.

When specifically using, move towards the backbone with first wire 2 and patient and aim at, be fixed in the patient body surface with rectangular frame 1 through the sticky tape, then adopt C arm machine to shoot the image, because 3 tip at every second wire are equipped with different mark symbol 4, be convenient for confirm in the perspective image should the line number of the section of performing the operation place, avoided confirming repeatedly, perspective radiation has been reduced, still be equipped with a plurality of location mark 5 on second wire 3 simultaneously, can confirm the needle insertion site more swiftly, reduce preoperative preparation time. The operation site is confirmed through a perspective image, and then the needle inserting site is determined on the surface of the patient body by combining with an operation positioning guide plate.
