Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to an orthopedic screwdriver. Background Technology

[0002] A screwdriver is a tool used to turn screws to force them into place. It typically has a thin, wedge-shaped head that inserts into the slot or recess of the screw head. Screwdrivers utilize the lever principle when used to pry open paint caps.

[0003] In the process of developing this application, the following problems were found with the technology: Most existing orthopedic splicing screwdrivers require adjustment of the position of the moving blade inside the blade shank before the positioning mechanism can engage the blade inside the blade shank. This makes it time-consuming for medical personnel to assemble the screwdriver, thus reducing the practicality of the device.

[0004] Therefore, an orthopedic screwdriver is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that most existing orthopedic screwdrivers require adjusting the position of the moving blade inside the shaft before the positioning mechanism can engage the blade, which makes it time-consuming for medical personnel to assemble the screwdriver. This utility model provides an orthopedic screwdriver.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] An orthopedic screwdriver includes a shank and a cutting head. The lower surface of the shank has a groove, and the cutting head is inserted into the groove. The upper surface of the shank has a retaining groove. The retaining groove and the groove of the shank are provided with a positioning mechanism to limit the position of the cutting head inside the shank.

[0008] Furthermore, the positioning mechanism includes two sets of insert rods, a warning light, a contact switch, a spring, an annular magnet, and an iron block. The iron block is installed on the upper surface of the cutter head. The annular magnet, the contact switch, and the spring are installed on the top of the inner wall of the cutter bar groove. A limit plate is installed at the bottom end of the spring. The upper surface of the iron block abuts against the lower surface of the limit plate. The warning light is snapped into the slot of the cutter bar. The annular magnet is located on the moving path of the limit plate. Through holes are opened on both the left and right sides of the cutter bar and the cutter head. The two sets of insert rods are respectively inserted into the two sets of through holes of the cutter bar. The two sets of through holes of the cutter head are located on the moving path of the two sets of insert rods. The control terminals of the contact switch and the warning light are electrically connected.

[0009] Furthermore, two sets of L-shaped limiting blocks are installed on the outer surface of the tool holder, and the inner sidewalls of the two sets of L-shaped limiting blocks are located on the moving path of the two sets of insert rods.

[0010] Furthermore, two sets of limiting rods are installed on the lower surface of the limiting plate, and two sets of positioning grooves are opened on the upper surface of the cutter head. The bottom ends of the two sets of limiting rods are respectively inserted into the two sets of positioning grooves of the cutter head.

[0011] Furthermore, an annular sealing gasket is installed on the lower surface of the cutter bar, and the inner wall of the annular sealing gasket abuts against the outer surface of the cutter head.

[0012] Furthermore, the inner wall of the tool bar is provided with two sets of positioning slots, and sliders are slidably connected inside the two sets of positioning slots. The adjacent sides of the two sets of sliders are respectively installed on the front and rear sides of the limiting plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model utilizes the magnetic attraction of a ring-shaped magnetic block to allow the blade head to slide within the groove of the blade rod. As the blade head slides within the groove, it pushes a limiting plate to press a contact switch, triggering a warning light that illuminates to indicate to medical personnel that the blade head has moved to the mounting and locking position. Then, by pushing two sets of insert rods, adjacent ends of the two sets of insert rods are respectively inserted into two sets of through holes in the blade head. This eliminates the need for medical personnel to adjust the position of the blade head within the groove of the blade rod during the locking and positioning process, thereby reducing the time and labor required for assembling the device and improving its practicality.

[0015] 2. This utility model pushes the cutter head to insert two sets of positioning grooves inside the cutter head into the outer ends of two sets of limiting rods. This allows the two sets of limiting rods to restrict the movement path of the cutter head inside the groove of the cutter bar, thereby minimizing the rotation of the cutter head inside the groove of the cutter bar during its movement. Consequently, the positions of the two sets of through holes inside the cutter head are moved out of the movement path of the two sets of inserting rods. This reduces the time and labor required for subsequent workers to insert the two sets of inserting rods into the two sets of through holes of the cutter head. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1 to 4As shown, an orthopedic screwdriver includes a shank 1 and a head 4. A groove is formed on the lower surface of the shank 1, and the head 4 is inserted into the groove. A slot is formed on the upper surface of the shank 1. A positioning mechanism 2 is provided inside the slot and groove of the shank 1 to limit the position of the head 4 within the shank 1. Specifically, by pushing the head 4, the positioning mechanism 2 is triggered and pushed to engage the head 4 inside the shank 1. This allows the positioning mechanism 2 to position the head 4 within the groove of the shank 1, eliminating the need for medical personnel to adjust or move the head 4 during the engagement process. This reduces the time and labor required for assembling the device, thus improving its practicality.

[0026] like Figures 1 to 4 As shown, the positioning mechanism 2 includes two sets of insert rods 201, a warning light 207, a contact switch 204, a spring 205, an annular magnetic block 203, and an iron block 202. The iron block 202 is installed on the upper surface of the cutter head 4. The annular magnetic block 203, the contact switch 204, and the spring 205 are installed on the top of the inner wall of the groove of the cutter bar 1. A limit plate 206 is installed at the bottom end of the spring 205. The upper surface of the iron block 202 abuts against the lower surface of the limit plate 206. The warning light 207 is snapped into the slot of the cutter bar 1. The position of the annular magnetic block 203 is located on the moving path of the limit plate 206. Through holes are opened on both the left and right sides of the cutter bar 1 and the cutter head 4. The two sets of insert rods 201 are respectively inserted into the two sets of through holes of the cutter bar 1. The positions of the two sets of through holes of the cutter head 4 are located on the moving path of the two sets of insert rods 201. The control terminals of the contact switch 204 and the warning light 207 are electrically connected.

[0027] Specifically, after the blade head 4 is inserted into the groove of the blade rod 1, the annular magnetic block 203 magnetically attracts the blade head 4 to slide within the groove of the blade rod 1. During the subsequent sliding of the blade head 4 within the groove of the blade rod 1, it pushes the limiting plate 206 to press the contact switch 204, triggering the warning light 207 to illuminate and prompt medical personnel to move the blade head 4 to the installation and locking position. Then, by pushing the two sets of insertion rods 201, the adjacent ends of the two sets of insertion rods 201 are respectively inserted into the two sets of through holes of the blade head 4. This eliminates the need for medical personnel to adjust or move the position of the blade head 4 within the groove of the blade rod 1 during the locking and positioning process, thereby reducing the time and labor required for medical personnel to assemble the device and improving its practicality.

[0028] like Figure 1 and Figure 2As shown, two sets of L-shaped limiting blocks 3 are installed on the outer surface of the tool bar 1. The inner sidewalls of the two sets of L-shaped limiting blocks 3 are located on the moving paths of the two sets of insertion rods 201. Specifically, by positioning the inner sidewalls of the two sets of L-shaped limiting blocks 3 on the moving paths of the two sets of insertion rods 201, the subsequent two sets of L-shaped limiting blocks 3 restrict the moving paths of the two sets of insertion rods 201 inside the two sets of through holes of the tool bar 1. This helps to prevent the subsequent two sets of insertion rods 201 from moving out of the two sets of through holes of the tool bar 1 during use and thus avoids the loss of the subsequent two sets of insertion rods 201, thereby improving the service life of the device.

[0029] like Figure 3 and Figure 4 As shown, two sets of limiting rods 6 are installed on the lower surface of the limiting plate 206, and two sets of positioning grooves are opened on the upper surface of the cutter head 4. The bottom ends of the two sets of limiting rods 6 are respectively inserted into the two sets of positioning grooves of the cutter head 4. Specifically, by pushing the cutter head 4, the two sets of positioning grooves inside the cutter head 4 are inserted into the outer ends of the two sets of limiting rods 6, so that the two sets of limiting rods 6 restrict the movement path of the cutter head 4 inside the groove of the cutter rod 1, thereby avoiding the rotation of the cutter head 4 inside the groove of the cutter rod 1 during the subsequent movement of the cutter head 4. This causes the positions of the two sets of through holes inside the cutter head 4 to move out of the movement path of the two sets of insert rods 201, thus reducing the time and labor required for the subsequent workers to insert the two sets of insert rods 201 into the two sets of through holes of the cutter head 4.

[0030] like Figure 1 As shown, an annular sealing gasket 5 is installed on the lower surface of the blade 1, and the inner wall of the annular sealing gasket 5 abuts against the outer surface of the blade head 4. Specifically, by the inner wall of the annular sealing gasket 5 abutting against the outer surface of the blade head 4, the annular sealing gasket 5 seals the connection gap between the blade head 4 and the blade 1, thereby minimizing the possibility of bodily fluids or medicines entering the groove of the blade 1 during subsequent use, which could lead to bacterial growth inside the blade 1 and thus improve the hygiene of the device during subsequent use.

[0031] like Figure 4 As shown, the inner wall of the tool holder 1 has two sets of positioning slots. Sliding sliders 7 are slidably connected inside each of the two sets of positioning slots. The adjacent sides of the two sets of sliders 7 are respectively installed on the front and rear sides of the limiting plate 206. Specifically, by sliding the two sets of sliders 7 inside the two sets of positioning slots of the tool holder 1, the sliding path of the limiting plate 206 within the groove of the tool holder 1 is restricted, thereby minimizing the risk of displacement of the limiting plate 206 during its sliding within the groove of the tool holder 1. This improves the stability of the limiting plate 206 during use.

[0032] In summary: The annular magnetic block 203 magnetically attracts the blade head 4 to slide within the groove of the blade rod 1. This sliding motion of the blade head 4 within the groove pushes the limiting plate 206, which in turn presses the contact switch 204 to trigger the warning light 207, prompting medical personnel to move the blade head 4 to the installation and locking position. Then, by pushing the two sets of insert rods 201, adjacent ends of the two sets of insert rods 201 are inserted into the two sets of through holes in the blade head 4. This eliminates the need for medical personnel to adjust the position of the blade head 4 within the groove of the blade rod 1 during the locking and positioning process, thus reducing the time and labor required for assembling the device. Furthermore, by pushing the blade head 4, the two sets of positioning grooves inside the blade head 4 are inserted into the outer ends of the two sets of limiting rods 6. This restricts the movement path of the blade head 4 within the groove of the blade rod 1, minimizing rotation within the groove during its movement.
