Description

Technical Field

[0001] The utility model discloses and relates to the technical field of orthopedic surgery, in particular to a puncture positioning device for intervertebral foraminal endoscopic surgery. Background Art

[0002] Perforaminal endoscopic lumbar discectomy is a minimally invasive spinal surgery technique that is performed under the guidance of images, after puncture positioning to reach the diseased intervertebral space, inserting the perforaminal endoscopic disc, and then performing the procedure under the microscope. In perforaminal endoscopic lumbar discectomy, accurate positioning of the puncture point is the key to the operation. In actual surgery, the surgeon needs to manually locate the puncture point with the assistance of X-ray fluoroscopy, and the operation mainly relies on the surgeon's subjective experience, which often leads to inaccurate positioning, deviation of the puncture position, and even failure of the operation. At the same time, the surgeon needs to perform fluoroscopy repeatedly during the operation, which not only increases the number of times the patient and the surgeon are exposed to radiation, prolongs the operation time, but also increases the risk of perforaminal endoscopic lumbar discectomy.

[0003] The existing puncture positioning device cannot be integrated with the surgical process, cannot be universally applicable to patients of different body shapes, and cannot accurately position the puncture process. Therefore, providing a puncture positioning device for transforaminal endoscopic surgery is an urgent problem to be solved. Utility Model Content

[0004] In view of this, the utility model discloses a puncture positioning device for percutaneous endoscopic lumbar disc surgery to improve the accuracy and safety of percutaneous endoscopic lumbar disc surgery.

[0005] The technical solution provided by the utility model is specifically a puncture positioning device for transforaminal endoscopic surgery, comprising a puncture positioning bed, a positioning slide arm, a puncture positioning rod, a fixing frame, a horizontal positioning component and a vertical positioning component;

[0006] The fixing frame is fixed to one side of the puncture positioning bed;

[0007] The vertical positioning assembly includes a connecting portion and a rotating portion; a through-hole structure is provided on the rotating portion body;

[0008] The fixing portion of the vertical positioning assembly is connected to the fixing frame;

[0009] The positioning slide arm is a curved structure, the upper end of which is inserted into the through-hole structure of the rotating part of the vertical positioning assembly, and the lower end is fixedly connected to the horizontal positioning assembly;

[0010] The puncture positioning rod is sleeved on the positioning slide arm, and the puncture positioning rod and the positioning slide arm move relative to each other.

[0011] The positioning slide arm assembly is marked with scales.

[0012] The positioning slide arm rotates 0-180 degrees with the rotating part of the vertical positioning component as the center.

[0013] The utility model provides a puncture positioning device for percutaneous endoscopic lumbar disc surgery. When puncture is required for patients of different body shapes, it is only necessary to clarify the required puncture needle insertion angle before the operation, and the puncture positioning device can eliminate the influence of body shape factors on puncture positioning; it can assist the operator to accurately confirm the puncture position and standardize the puncture needle insertion angle; in the actual operation process, after using the puncture positioning device, there is no need to repeatedly adjust the puncture needle insertion angle, which reduces the influence of previous subjective operations on accurate puncture positioning; by applying the puncture positioning device, the accuracy of the puncture needle angle selection can be effectively controlled, the number of X-ray fluoroscopy times during the operation can be reduced, and the accuracy and safety of percutaneous endoscopic lumbar disc surgery can be effectively improved.

[0019] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of systems consistent with some aspects of the utility model as detailed in the attached claims.

[0020] In order to solve the problems that the puncture positioning device in the prior art cannot be integrated with the surgical process, cannot be generally applicable to patients of different body shapes, and cannot accurately position the puncture process, the present embodiment provides a puncture positioning device for transforaminal endoscopic lumbar surgery, including a puncture positioning bed 1, a positioning slide arm 2, a puncture positioning rod 3, a fixing frame 4, a horizontal positioning component 5 and a vertical positioning component 6;

[0021] The fixing frame 4 is fixed to one side of the puncture positioning bed 1;

[0022] The vertical positioning assembly 6 includes a connecting portion and a rotating portion; a through-hole structure is provided on the rotating portion body; the rotating portion is located directly above the positioning slide arm 2 to determine the initial neutral position of the positioning slide arm assembly and the vertical needle insertion angle during the puncture process.

[0023] The fixing portion of the vertical positioning assembly 6 is connected to the fixing frame 4;

[0024] The positioning slide arm 2 is a curved structure, the upper end of which is inserted into the through-hole structure of the rotating part of the vertical positioning assembly, and the lower end is fixedly connected to the horizontal positioning assembly 5; the positioning slide arm 2 is marked with a scale to indicate the angle of the puncture positioning rod;

[0025] The connecting portion may be a long strip-shaped connecting block 61, the rotating portion may be a rotating shaft structure 62 in the prior art, and the positioning slide arm 2 rotates 0-180 degrees around the rotating portion of the vertical positioning assembly 6 to adjust the angle of the puncture positioning plane during the puncture process;

[0026] The horizontal positioning assembly 5 is located below the positioning slide arm 2 and is used to mark the horizontal needle insertion angle during the reference puncture process.

[0027] The puncture positioning rod 3 is sleeved on the positioning slide arm 2, and the puncture positioning rod 3 and the positioning slide arm 2 move relative to each other.

[0028] The puncture positioning rod 3 is sleeved with the positioning slide 2, and the puncture positioning rod 2 can be slid along the positioning slide assembly 3, that is, the puncture positioning rod 3 and the positioning slide 2 can move relative to each other. At the same time, since the upper end of the positioning slide 2 is inserted into the through-hole structure of the rotating part of the vertical positioning assembly, the positioning slide 2 can pass through the puncture positioning rod 3 and the through-hole structure to perform puncture positioning at a predetermined puncture angle.

[0029] The puncture needle is connected to the puncture positioning rod for puncture, and the position of the puncture positioning rod determines the needle insertion angle during the puncture process.

[0030] In the actual puncture positioning process, the required anteroposterior and lateral angles of the puncture needle are first determined through the preoperative anteroposterior and lateral spine radiographs. By adjusting the position of the positioning slide 2 above the puncture positioning bed 1, the vertical positioning component 6 is rotated to the required angle with the rotating part as the center, and after fixing, the horizontal positioning component 5 is used as a reference to adjust the position of the puncture positioning rod 3 on the positioning slide 2 along the marking scale of the positioning slide 2 to determine the accurate puncture angle and finally select the appropriate puncture point. Figure 2 As shown, the above-mentioned push-pull positioning slide arm 2 is used to adjust the position of the puncture positioning rod 3 on the positioning slide arm 2.

[0031] like Figure 2 As shown, when the puncture positioning device is used to locate the puncture point during transforaminal endoscopic lumbar discectomy, the required anteroposterior angle of the puncture needle is first determined through the preoperative anteroposterior and lateral spine radiographs. By adjusting the position of the positioning slide assembly 2 on the fixed frame assembly 4, the vertical positioning assembly 6 is rotated to the required angle, and after fixing, the horizontal positioning assembly 5 is used as a reference, and the position of the puncture positioning rod assembly 3 on the positioning slide arm 2 is adjusted along the marked scale of the positioning slide arm 2 to determine the accurate puncture angle, and finally select the appropriate puncture point. During the operation, the puncture positioning device can be used to perform accurate puncture positioning according to actual conditions.

[0032] Those skilled in the art will readily come up with other embodiments of the present invention after considering the specification and practicing the utility model disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary technical means in the art that are not disclosed in the present invention. The specification and examples are to be considered as exemplary only, and the true scope and spirit of the present invention are indicated by the claims.
