Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to an anesthetic puncture guiding device. Background Art

[0002] In the existing medical technology, the anesthetic puncture process often requires doctors to operate based on experience and vision, and this method has some problems. First, it is difficult to ensure the accuracy of puncture, which may lead to multiple punctures, increasing the pain of patients and the surgical risk. Second, the existing puncture guiding devices have relatively complex structures, are not convenient to operate, and have high costs, which is not conducive to wide promotion and use. In addition, the existing guiding devices also have deficiencies in terms of stability and adjustment accuracy, and cannot meet the needs of different patients and surgical scenarios. Therefore, it is of great clinical significance to develop an anesthetic puncture guiding device with a simple structure, convenient operation, low cost, and precise adjustment. Summary of the Invention

[0003] (1) Technical Problems to be Solved

[0004] In view of the deficiencies of the existing technology, the present invention provides an anesthetic puncture guiding device, which solves the problems of low puncture accuracy, complex operation, high cost, and insufficient stability existing in the existing technology.

[0005] (2) Technical Solutions

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An anesthetic puncture guiding device includes a fixed frame. A connecting seat is fixedly connected to the upper side wall of the fixed frame. A mating sleeve is threadedly connected inside the connecting seat. An adjusting rod is rotatably connected inside the mating sleeve. A sliding piston is rotatably connected to the lower end of the adjusting rod. Limit sliding seats are fixedly connected to both the left and right side walls of the fixed frame. A positioning frame is slidably connected inside the limit sliding seats;

[0007] Two symmetrically arranged supporting top frames are fixedly connected to the upper side wall of the fixed frame. A mating frame is fixedly connected to the lower side wall of each supporting top frame. A supporting convex is slidably connected inside each mating frame. A sliding block is fixedly connected to the lower side wall of each supporting convex. The lower ends of the two sliding blocks are slidably connected to the same sliding frame;

[0008] A rolling seat is fixedly connected to the middle of the sliding frame. A supporting ball is rotatably connected inside the rolling seat. A needle outlet groove is arranged inside the supporting ball. A limit groove is arranged on the upper side wall directly above the needle outlet groove inside the supporting ball. An electromagnet sleeve is installed inside the rolling seat.

[0009] Preferably, two limiting bottom plates are fixedly connected to the lower side wall of the fixing frame. The limiting bottom plates and the fixing frame are made by an integral molding technique. The combination of the limiting bottom plates and the fixing frame enables the device to cooperate with the armrest of the hospital bed.

[0010] Preferably, a sealing sleeve is installed on the lower inner wall of the fixing frame. The sealing sleeve is made of silica gel material and is arranged in a square ring shape, which can effectively improve the sealing performance between the device and the upper side wall of the armrest.

[0011] Preferably, an air inlet hole is arranged inside the sliding piston, a connecting groove is arranged inside the adjusting rod, an air outlet groove is fixedly connected inside the adjusting rod and above the connecting groove, and an air outlet hole is arranged inside the matching sleeve. The air outlet hole is flush with the air outlet groove, so that the inner cavity formed by the armrest and the upper inner wall of the fixing frame is communicated with the outside through the air inlet hole, the connecting groove, the air outlet groove and the air outlet hole.

[0012] Preferably, a turntable is fixedly connected to the upper end of the matching sleeve. The matching sleeve can be driven to rotate through the turntable. An adjusting disc is fixedly connected to the upper end of the adjusting rod, and a rotating rod is fixedly connected to the outer side wall of the adjusting disc. The adjusting disc can be driven to rotate through the rotating rod, so as to drive the adjusting rod to rotate, and further adjust the included angle between the air outlet hole and the air outlet groove.

[0013] Preferably, a support spring is arranged between the inner side walls of the positioning frame and the limiting sliding seat. The arrangement of the support spring enables the limiting sliding seat to support the side wall of the armrest. A matching rolling ball is rotatably connected to the inner side wall of the positioning frame. The arrangement of the matching rolling ball facilitates the sliding of the fixing frame and the armrest.

[0014] Preferably, two sliding grooves are arranged on the upper side wall of the sliding frame. Each sliding groove is slidably connected with a sliding block, which is convenient for the sliding block to slide with the sliding frame. A power supply assembly is installed inside the rolling seat. The power supply assembly is electrically connected to the electromagnet sleeve for supplying power to the electromagnet sleeve.

[0015] Preferably, the right ends of the two support top frames are fixedly connected to the same fixed side frame. An adjusting screw rod is threadedly connected inside the fixed side frame. By rotating the adjusting screw rod, the stability of the left - right sliding of the rolling seat can be driven. The left end of the adjusting screw rod is rotatably connected to the rolling seat. An isosceles trapezoid is formed among the fixing frame, the support top frames and the fixed side frame, which effectively improves the stability of the support for the fixed seat. A support rib plate is fixedly connected between each support top frame and the fixing frame to improve the support strength of the support top frame.

[0016] Working principle: When using the device, first, slide the fixing frame onto the handrail of the hospital bed. The setting of the limit bottom plate can effectively prevent the sliding frame from falling off. The setting of the positioning frames on both sides can clamp both the left side wall and the right side wall of the hospital bed handrail. Then, press down the fixing frame so that the sealing sleeve fits against the upper side wall of the fixing frame, and drive the matching sleeve to move downward through the turntable, thereby driving the sliding piston to move upward. As a result, the internal air pressure in the cavity between the upper side wall of the hospital bed handrail, the sealing sleeve, and the connecting seat decreases, greatly improving the adsorption stability between the fixing frame and the hospital bed handrail. Then, drive the rolling frame to move left and right by rotating the adjusting screw rod, thereby adjusting the position of the support ball. Finally, roll and adjust the support ball. After adjusting the angle of the needle outlet groove, fix the support ball by energizing the electromagnet sleeve. Slide the anesthetic needle into the needle outlet groove and then perform anesthetic work on the patient.

[0017] (III) Beneficial effects

[0018] The present invention provides an anesthetic puncture guiding device, which has the following beneficial effects:

[0019] 1. The device is provided with a fixing frame and an adjusting disk. The fixing frame can clamp both the left side wall and the right side wall of the hospital bed handrail through the setting of the positioning frames on both sides. The internal air pressure in the cavity between the sealing sleeve and the connecting seat decreases due to the setting of the matching sleeve and the connecting seat, thereby greatly improving the adsorption stability between the fixing frame and the hospital bed handrail. By rotating the adjusting disk, the air outlet groove can be aligned with the air outlet hole, facilitating the separation of the fixing frame from the handrail. The setting of the fixing frame and the adjusting disk can effectively improve the stability of the installation of the device on the hospital bed handrail, the convenience of disassembly or installation, and thus effectively improve the stability of puncture guidance.

[0020] 2. The device is provided with a support top frame, a fixed seat, and an adjusting screw rod. By rotating the adjusting screw rod to drive the rolling frame to move left and right, the position of the support ball can be adjusted. Roll and adjust the support ball to adjust the angle of the needle outlet groove. The setting of the support top frame can improve the sliding stability of the sliding frame and the rolling seat. The combination of the three can effectively and accurately adjust and position the puncture angle and puncture position, greatly reducing the puncture error. Description of the drawings
