Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an orthopedic surgical drilling device. Background Technology

[0002] During orthopedic surgery, it is sometimes necessary to drill holes in the bone. Currently, lasers are usually used for positioning when drilling. When drilling, it is impossible to drill precisely according to the specific angle of the laser emission. Moreover, the laser only marks a point on the bone. When drilling manually, it is possible to drill crookedly or fail to drill, which will not only damage the bone but also affect the fixation of the steel plate later. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide an orthopedic surgical drilling device to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this orthopedic surgical drilling device to solve its technical problems is as follows:

[0005] An orthopedic surgical drilling device is provided, including a slide rod and a bracket. The bracket is fixedly installed on both sides of the slide rod. A first slip ring is fitted into the middle of the slide rod. A first support arm is rotatably installed below the first slip ring via a bearing. A second support arm is hinged to the lower end of the first support arm. One end of a third support arm is hinged to the lower end of the second support arm. The other end of the third support arm is rotatably connected to a support rod via a bearing. Electric brakes for preventing rotation are provided inside the first slip ring, at the connection between the first slip ring and the first support arm, at the connection between the first support arm and the second support arm, at the connection between the second support arm and the third support arm, and at the connection between the third support arm and the support rod. A vertical tube is fixedly installed on the support rod, and a switch with a circuit simultaneously connected to each electric brake is provided on the vertical tube. A second slip ring is movably installed on the slide rod. A ball seat is fixedly installed at the bottom of the second slip ring, and a rolling ball is provided inside the ball seat. A laser spotlight is fixedly installed at the bottom of the rolling ball.

[0006] Furthermore, a limiting groove is provided at the bottom of the vertical pipe, and a limiting slider is provided in the limiting groove. A groove is provided at the top of the limiting slider, and a switch is fixedly installed in the groove. The switch is a photoelectric switch, and the photoelectric switch is connected to each electric brake through a circuit.

[0007] Furthermore, a receiving block is fixedly installed on one side of the vertical pipe.

[0008] Furthermore, an external thread is formed on the upper part of the outer periphery of the vertical tube, and a threaded tube is threadedly installed thereon.

[0009] Furthermore, the second slip ring, ball seat, rolling ball, and laser spotlight are in two sets, and the two sets are respectively arranged on both sides of the first slip ring.

[0010] Furthermore, the top of the second slip ring is provided with threaded through grooves, and fixing bolts are threadedly installed in the threaded through grooves.

[0011] Furthermore, an electric slide rail is provided below the bracket, and the bracket is fixedly installed on the slider of the electric slide rail.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides an orthopedic surgical drilling device. When using this device, the positions of the sliding rod and support are adjusted, and the laser spotlight is adjusted according to the drilling position and angle. After fixing the second sliding ring by rotating the fixing bolt, the position of the vertical tube is adjusted so that the laser spotlight's light enters the vertical tube and exits. By switching on and controlling the electric brake, the corresponding moving parts are locked, allowing the drill bit to be inserted into the vertical tube. The vertical tube positions the drill bit for drilling into the bone. This device allows for convenient and quick positioning of the drilling position and angle, and guides the drill rod during drilling based on the positioning position, making drilling more precise and easier to use.

[0014] 2. In the example of this utility model, an orthopedic surgical drilling device is used by inserting a limiting slider into a limiting groove, adjusting the position of the laser spotlight so that it faces the drilling position according to the drilling angle, and then adjusting the vertical tube to irradiate the laser into the vertical tube. When the laser irradiates the photoelectric switch, the photoelectric switch controls the electric brake to start, locking all moving parts. After removing the limiting slider, the bone drill rod can be inserted into the vertical tube for drilling.

[0015] 3. In the example of the orthopedic surgical drilling device of this utility model, when in use, the limiting slider can be placed in the receiving block after being pulled out, so as to avoid the limiting slider sagging and affecting the drilling operation.

[0016] 4. An orthopedic surgical drilling device according to this utility model can adjust the drilling depth through a threaded tube, making the drilling depth more precise.

[0017] 5. An orthopedic surgical drilling device according to this utility model can select the appropriate angle of the laser spotlight according to the surgical position by means of laser spotlights arranged on both sides of the first slip ring.

[0018] 6. In the example of the orthopedic surgical drilling device of this utility model, after determining the angle of the laser spotlight, the second slip ring can be fixed by tightening the fixing bolt.

[0019] 7. An orthopedic surgical drilling device according to this utility model can drive the support and slide rod to move precisely by activating the electric slide rail. Attached Figure Description
