Description

Technical Field

[0001] This utility model relates to the field of drilling positioning technology, and more specifically to a drilling positioning device. Background Technology

[0002] Orthopedics is one of the most common departments in major hospitals, and fractures are a common clinical condition in orthopedics. When treating fractures, reduction with bone screws is the most common medical method. Current reduction techniques generally use Kirschner wires or fixation plates to reduce and fix the fracture site. These medical devices require positioning and drilling before installation, necessitating surgery by a surgeon using a drilling device to drill holes in the bone before installing these devices.

[0003] For example, in the prior art publication number CN220495051U, there is a drilling device for clinical use in orthopedics. This utility model enhances the stability of the device through two hydraulic rods, preventing shaking and displacement during surgery and causing secondary injury to the patient. The forward rotation of the motor drives the rotating shaft and the threaded rod to rotate in the same direction, thereby adjusting the left and right movement of the positioning block and the connecting seat, which facilitates the adjustment of the working position of the drill bit by medical personnel and increases the accuracy of the surgery.

[0004] However, the existing technology has the following problems when used: bone fragments are generated during drilling surgery. When bone fragments collide with the drill bit, they will cause the drill bit to deviate and vibrate, affecting the positioning accuracy of the drill bit and seriously affecting the safety of the operation. They will also be ejected into the skin layer and affect the health of the skin layer. Furthermore, the closing of the separated skin layer will also affect the positioning accuracy of the drill bit. Based on this, the present invention provides a drilling positioning device. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a drilling positioning device. An infrared locator helps doctors quickly determine the drilling location. Simultaneously, the positioning cylinder fits snugly against the bone, serving as a secondary positioning mechanism and separating the bone from the skin layer. This prevents accidental skin damage during drilling and avoids bone fragments from the drilling entering the skin layer, causing inflammation and swelling. Furthermore, an adjustment component and a motor drive the drill bit to rotate and descend, drilling into the bone. This avoids the inaccuracies of manual drilling positioning, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drilling positioning device, including a mounting frame and a positioning component one, the positioning component one including a bracket, a cylinder rotatably disposed inside the bracket, two opposite mounting holes being opened on the outer wall of the cylinder, wherein a detachable motor and an infrared locator are respectively fixed in the two mounting holes, a detachable drill bit is fixed on the output shaft of the motor, and the bracket is connected to the mounting frame through an adjustment component;

[0007] Positioning component two includes a positioning cylinder, which is sleeved on the outside of the drill bit. Two detachable electric push rods are fixedly installed on both sides of the top of the positioning cylinder, and the two electric push rods are fixedly embedded in the bottom of the bracket.

[0008] In a preferred embodiment, the positioning cylinder has an air chamber inside, and the inner wall surface of the positioning cylinder has multiple suction ports that communicate with the air chamber. A suction tube that communicates with the air chamber is fixedly inserted through the top of the positioning cylinder, and the suction tube is connected to a suction device. A silicone ring is fixedly installed at the bottom of the positioning cylinder. The silicone ring is made of soft material, and medical silicone is selected in actual use, so as to play a buffering role between the bone and the positioning cylinder.

[0009] In a preferred embodiment, the adjustment assembly includes an electric push rod II. The bottom end of the piston rod of the electric push rod II is fixed to the top end of the bracket. A movable plate is fixedly sleeved on the cylinder end of the electric push rod II. The bracket is moved up and down by the electric push rod II, thereby driving the drill bit to drill automatically and avoiding inaccurate positioning during manual drilling.

[0010] In a preferred embodiment, two symmetrically distributed electric slides are fixedly provided at the top front end of the mounting frame, and the movable plate is located between the two electric slides. The two electric slides can make the drill bit move back and forth more stably.

[0011] In a preferred embodiment, electromagnetic locks are fixedly inserted through both outer walls of the support, and multiple slots are provided on both outer walls of the cylinder. The electromagnetic lock is inserted into one of the slots. By cooperating with the slot, the cylinder is firmly fixed, which not only makes it convenient for medical staff to rotate the cylinder, but also improves the firmness between the cylinder and the support.

[0012] In a preferred embodiment, the mounting frame has a mounting groove at the bottom of its front end, and two bolts pass through the bottom of the mounting groove. Both bolts are threaded to the mounting frame, and a pad is fixed to the top of each bolt. Tightening the bolts makes the pad firmly abut against the bottom of the operating table, thus firmly fixing the mounting frame to the operating table for use, while also facilitating quick disassembly of the mounting frame.

[0013] In a preferred embodiment, the mounting bracket has a cable management hole at its front end, which is located between the electric slide and the mounting groove. The rear end of the suction tube passes through the cable management hole, which supports the suction tube and prevents it from affecting the drilling work.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model uses an infrared locator to help doctors quickly determine the location of the drill hole. At the same time, the positioning cylinder fits into the bone, which can not only play a secondary positioning role, but also separate the bone from the skin layer, avoiding accidental damage to the skin layer during drilling and preventing bone fragments from the drilling from hitting the skin layer and causing inflammation and swelling. With the help of the adjustment component and motor, the drill bit is rotated and moved down to drill holes in the bone, avoiding the inaccuracy of manual drilling positioning.

[0016] 2. Medical staff connect the suction tube to the suction device and use the suction device to draw out the bone fragments through the suction port. This not only avoids the bone fragments affecting the drilling work of the drill bit, but also saves time for subsequent cleaning of bone fragments, making it more time-saving and labor-saving.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Refer to the instruction manual appendix Figure 1-6 This utility model provides a drilling positioning device, including a mounting frame 1 and a positioning component 2. The positioning component 2 includes a bracket 201, a cylinder 202 rotatably disposed inside the bracket 201, and two opposing mounting holes 203 opened on the outer wall of the cylinder 202. A detachable motor 204 and an infrared locator 205 are respectively fixed in the two mounting holes 203. A detachable drill bit 206 is fixed on the output shaft of the motor 204.

[0029] And positioning component 2 4, which includes positioning cylinder 401, which is sleeved on the outside of drill bit 206. Two detachable electric push rods 402 are fixedly provided on both sides of the top of positioning cylinder 401, and the two electric push rods 402 are fixedly embedded in the bottom of bracket 201.

[0030] To prevent the positioning cylinder 401 from damaging the patient's bones, a silicone ring 9 is fixed at the bottom of the positioning cylinder 401. The silicone ring 9 is made of soft material, and medical silicone is selected in actual use so as to play a buffering role between the bone and the positioning cylinder 401.

[0031] To facilitate the adjustment of the position of the drill bit 206, the bracket 201 is connected to the mounting bracket 1 via an adjustment component 3. The adjustment component 3 includes an electric push rod 301. The bottom end of the piston rod of the electric push rod 301 is fixed to the top end of the bracket 201. A movable plate 302 is fixedly sleeved on the cylinder end of the electric push rod 301. The bracket 201 is moved up and down by the electric push rod 301, thereby enabling the drill bit 206 to automatically drill holes and avoiding inaccurate positioning during manual drilling.

[0032] Furthermore, two symmetrically distributed electric slides 303 are fixedly provided at the top front end of the mounting bracket 1, and the moving plate 302 is located between the two electric slides 303. The two electric slides 303 can make the drill bit 206 more stable when moving back and forth.

[0033] To facilitate switching the positions of the drill bit 206 and the infrared locator 205, electromagnetic locks 10 are fixedly inserted through both outer walls of the bracket 201. Multiple slots 11 are provided on both outer walls of the cylinder 202. The electromagnetic lock 10 is inserted into one of the slots 11. By cooperating with the slot 11, the cylinder 202 is firmly fixed, which not only makes it convenient for medical staff to rotate the cylinder 202, but also improves the stability between the cylinder 202 and the bracket 201.

[0034] In use, the doctor first fixes the mounting frame 1 on the operating table, determines the bone location that needs to be drilled by using the patient's X-ray or CT scan image, and marks it on the skin for subsequent surgery. Then, the cylinder 202 is rotated so that the infrared locator 205 emits a laser beam onto the patient's skin. The position of the drill bit 206 can be quickly determined by the laser beam and the skin mark. The doctor uses a surgical knife to cut open the skin layer at the drilling site with the help of the laser beam. After the bone to be drilled is exposed, the doctor first cleans the wound. After cleaning, the electric push rod 402 drives the silicone ring 9 at the bottom of the positioning cylinder 401 to fit with the bone, and at the same time opens the solenoid valve, rotates the cylinder 202 so that the drill bit 206 faces downward. At this time, the drill bit 206 and the bone drilling position are on the same axis, and no further positioning is required.

[0035] The positioning cylinder 401 separates the skin layer, which can serve as a secondary positioning function and prevent accidental damage to the skin layer during drilling, thus avoiding bone fragments from being ejected into the skin layer and causing inflammation and swelling. Then, the electric push rod 301 drives the cylinder 202 to move down, while the motor 204 drives the drill bit 206 to rotate, so that a hole can be drilled in the bone.

[0036] To facilitate the cleaning of bone debris produced during drilling, please refer to the attached instruction manual. Figure 1-6 An air chamber 5 is provided inside the positioning cylinder 401. Multiple suction ports 6 connected to the air chamber 5 are opened on the inner wall surface of the positioning cylinder 401. A suction tube 7 connected to the air chamber 5 is fixedly inserted through the top of the positioning cylinder 401. A suction device 8 is connected to the suction tube 7.

[0037] When drilling, medical staff can connect the suction tube 7 to the suction device 8 and use the suction device 8 to generate suction to suck out the bone fragments through the suction port 6. Alternatively, the suction tube 7 can be connected to the bone fragment remover and the bone fragment remover can be used for suction and cleaning. This can not only prevent bone fragments from affecting the drilling work of the drill bit 206, but also save time for subsequent bone fragment cleaning, making it more time-saving and labor-saving to use.

[0038] To facilitate the fixing of the mounting bracket 1, a mounting groove 12 is provided at the bottom front end of the mounting bracket 1. Two bolts 13 pass through the bottom end of the mounting groove 12. Both bolts 13 are threaded to the mounting bracket 1. A pad 14 is fixed to the top of each of the two bolts 13. Tightening the bolts 13 makes the pad 14 firmly abut against the bottom of the operating table, so that the mounting bracket 1 can be firmly fixed to the operating table for use, and at the same time, it is easy to quickly disassemble the mounting bracket 1.

[0039] To prevent the suction tube 7 from sagging, a cable management hole 15 is provided at the front end of the mounting bracket 1. The cable management hole 15 is located between the electric slide table 303 and the mounting groove 12. The rear end of the suction tube 7 passes through the cable management hole 15, and the cable management hole 15 supports the suction tube 7 to prevent the suction tube 7 from affecting the drilling work.
