Description

Technical Field

[0001] This utility model relates to the field of surgical instrument fixation, and in particular to an auxiliary device for fixing surgical instruments. Background Technology

[0002] In various surgical procedures, some surgical instruments, after being moved to the appropriate position, need to remain in a fixed position for an extended period. This prolonged posture maintenance greatly increases the surgeon's workload and reduces surgical efficiency. Currently, there is an urgent clinical need for an auxiliary surgical instrument that can flexibly adjust the surgical instruments and stably maintain them in a fixed spatial position and posture.

[0003] There are now specialized fixation devices for holding and supporting surgical instruments. However, most fixation devices on the market are one-piece designs, and the whole device needs to be reused. It needs to be cleaned and disinfected before and after each use. This not only increases the workload of disinfection personnel, but if the disinfection is not complete, bacteria will be carried over to the next use, causing infection during surgery.

[0004] Traditional surgical clamping and fixation devices have the following technical drawbacks: 1. The use of a fully mechanical locking structure results in poor stability of the surgical instruments' posture. Furthermore, after prolonged use, the instruments wear down and are prone to micro-movements, which can affect surgical procedures and increase surgical risks.

[0005] 2. Traditional surgical clamping and fixation devices can only clamp customized special surgical instruments and cannot be compatible with conventional surgical instruments or surgical endoscopes at the same time, which limits their application scenarios.

[0006] 3. Traditional surgical clamping and fixation devices require manual pressure to lock the mechanical structure during the locking process, which increases the surgeon's operating steps and makes it inconvenient for the surgeon to move and fix the surgical instruments randomly.

[0007] 4. In traditional surgical clamping and fixation devices, the clamping part and the installation part are connected as one piece, and repeated cleaning and disinfection are required. If the cleaning and disinfection is not thorough, bacteria may be present, posing a risk of infection. Utility Model Content

[0008] The purpose of this invention is to provide a surgical instrument fixation auxiliary device, in which the cylinders attract each other to maintain their position after the electromagnet is energized, making it easy to adjust.

[0009] To solve the above technical problems, the following technical solution is adopted: This utility model provides a surgical instrument fixing auxiliary device, including a clamping part, a joint shaft, and a mounting part. One end of the joint shaft is connected to the mounting part. The mounting part is used to install the entire auxiliary device on the side of the operating table. The clamping part is used to clamp the surgical instrument and is a disposable consumable. The joint axis includes several cylinders with saddle surfaces on both the upper and lower ends. The upper and lower ends of the cylinders are connected in series by an axis. The axis is connected to the clamping part and controls the opening and closing of the clamping part. An electromagnet is provided in the mounting part. When the electromagnet is energized, it conducts magnetism onto the cylinders, so that the cylinders are attracted together and maintain their position.

[0010] Optionally, the joint shaft further includes two end cylinders, each with a saddle surface on one end face. One end cylinder without a saddle surface is connected to the mounting part, and the other end cylinder without a saddle surface is connected to the clamping part. The end faces of both end cylinders with saddle surfaces are connected to the cylinders.

[0011] Optionally, the end cylinder connected to the mounting part is provided with a sector-shaped chuck, and the mounting part is provided with a slot that mates with the sector-shaped chuck.

[0012] Optionally, the joint shaft and the axis are made of permalloy.

[0013] Optionally, the saddle surfaces of the upper and lower end faces of the cylinder are at a 90-degree angle, and two adjacent saddle surfaces are staggered at a 90-degree angle.

[0014] Optionally, the power supply battery is connected to the electromagnet via a power control board to control the opening and closing of the electromagnet. When the electromagnet is on, it attracts the axis in the joint shaft, thereby pulling the mechanical claw of the clamping part to close the mechanical claw. When the electromagnet is closed, it releases the axis, thereby releasing the mechanical claw. The working state of the electromagnet is controlled by a button located on the end of the joint shaft near the clamping part.

[0015] Optionally, the mounting part includes a housing, a fixed gripper, a movable gripper, and an adjustment knob. The fixed gripper is disposed on the housing, and the movable gripper is movably connected to the inside of the housing by a spring and a connecting pin. One end of the movable gripper extends out from the inside of the housing and cooperates with the fixed gripper to form a gripper. The adjustment knob is used to adjust the opening and closing of the gripper.

[0016] Optionally, the clamping part includes a robotic arm for clamping surgical instruments.

[0017] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: 1. This utility model adjusts the position of the clamping part by means of a joint axis. The joint axis maintains its position when energized by an electromagnet, and adjusts the position of the joint axis when the electromagnet is de-energized. During use, the state of the end clamping part can be precisely adjusted, which is convenient for use. The opening and closing of the clamping part is controlled by the axis, which can adapt to clamping surgical instruments of different sizes.

[0018] 2. The joint axis and the axis of this utility model are both composed of cylinders made of permalloy. The ends of the cylinders are connected by saddle surfaces, which makes the adjustment of the joint axis smoother. When the electromagnet is energized, the permalloy can stably maintain the position due to its magnetic conductivity. Attached Figure Description

[0023] This embodiment provides a surgical instrument fixation auxiliary device, including a clamping part 9, a joint shaft 8, and a mounting part. The clamping part 9 is connected to the mounting part through the joint shaft 8. The mounting part is used to install the entire auxiliary device in the use position. The clamping part 9 is used to clamp surgical instruments and is a disposable consumable. like Figure 1 , Figure 4 , Figure 5 , Figure 7 As shown, the joint shaft 8 includes several cylinders 81 with saddle surfaces 811 on both the upper and lower end faces. The upper and lower end faces of the several cylinders 81 are connected in series by an axis. The axis is connected to the clamping part 9 and controls the opening and closing of the clamping part 9. An electromagnet 5 is provided in the mounting part. The electromagnet 5 is used to conduct magnetism to the cylinders 81 when energized, so that the several cylinders 81 are attracted together and maintain their position.

[0024] In use, the entire auxiliary device is installed on the side of the operating table via the mounting part, and the instruments used in the operation are held by the clamping part 9. After the electromagnet 5 is de-energized, the joint axis 8 is adjusted to keep the surgical instruments at a certain height and angle. After the adjustment is completed, the electromagnet 5 is energized, so that several cylinders 81 become magnetic and attract each other together to maintain their position.

[0025] The clamping part 9 is a disposable consumable, while the joint shaft 8 and the mounting part can be used multiple times. The clamping part 9 needs to directly contact the surgical instruments. By making the clamping part 9 a disposable consumable, the contamination of the surgical instruments is reduced, making it safer.

[0026] The joint shaft 8 has an internal axis, which is connected to the clamping part 9 to drive the opening and closing of the clamping part 9. The axis connects the joint shafts 8 into a whole. After adjustment, the position of the joint shaft 8 is maintained by energizing the electromagnet 5. At the same time, the joint shaft 8 attracts the axis, closing the clamping part at the end, thereby clamping the surgical instrument. Example 2

[0027] This embodiment provides a surgical instrument fixation auxiliary device based on Embodiment 1.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 7 As shown, the joint shaft 8 consists of several cylinders 81 with saddle surfaces 811 at both ends and two end cylinders 81 with saddle surfaces 811 on only one end. The end of one end cylinder 81 without a saddle surface 811 is connected to the mounting part, and the end of the other end cylinder 81 without a saddle surface 811 is connected to the clamping part 9. The ends of the two end cylinders 81 with saddle surfaces 811 respectively mate with the saddle surfaces 811 on the other cylinders 81. The saddle surfaces 811 on the upper and lower end faces of the cylinders 81 are arranged at a 90-degree angle, and adjacent mating saddle surfaces 811 are staggered at a 90-degree angle. The number of cylinders 81 can be increased or decreased according to the needs of surgery, facilitating use.

[0029] like Figure 8 As shown, the end cylinder 81 connected to the mounting part is provided with a sector-shaped chuck 82. Two sector-shaped chucks 82 are symmetrically arranged on the side wall of the lower end of the end cylinder 81. The mounting part is provided with a slot that cooperates with the sector-shaped chuck 82. By cooperating with the slot, the end cylinder 81 is mounted on the mounting part.

[0030] like Figure 3 , Figure 5As shown, the mounting section also includes a power supply battery 7, which is connected to the electromagnet 5 via a power control board 6. The operating state of the electromagnet 5 is controlled by a button 10 located on the end of the joint shaft 8 near the clamping part 9. Pressing the button 10 after adjusting the joint shaft 8 energizes the electromagnet 5. When energized, the electromagnet 5 generates a magnetic field, which is transmitted to the cylinders 81. Several cylinders 81 become magnetic and attract each other, maintaining their position. The cylinders 81 are made of permalloy, which readily conducts magnetism. The magnetic field generated by the electromagnet 5 makes the cylinders 81 magnetic, causing them to attract each other. When the battery is not supplying power to the electromagnet 5, the electromagnet 5 does not generate a magnetic field, and the cylinders 81 are connected only by their central axis. The position of several cylinders 81 can be adjusted, and then the electromagnet 5 is activated to maintain the adjusted position, facilitating the use of the end clamping part 9.

[0031] The shaft connected to the clamping part 9 is also made of permalloy. When the electromagnet 5 is energized, the cylinders 81 attract each other and also attract the shaft, pulling it towards the mounting part, thereby closing the clamping part 9 and clamping the surgical instrument. When the electromagnet 5 is de-energized, the shaft is released and the clamping part 9 opens.

[0032] like Figure 3 As shown, the clamping part 9 includes a robotic arm 11, which is mounted on the end cylinder 81 and connected to the axis. The robotic arm 11 is opened and closed by the control of the axis and the electromagnet 5. In this embodiment, the robotic arm 11 can be an Epson VT6L.

[0033] like Figure 5 , Figure 6 As shown, the mounting part includes a housing, a fixed gripper 3, and a movable gripper 1. The fixed gripper 3 is located on the outside of the housing, and the movable gripper 1 is mounted on the inside of the housing via a connecting pin and a spring 2. The spring 2 is mounted on the connecting pin, with one end abutting against the fixed pin next to the movable gripper 1. One end of the movable gripper 1 extends from the inside of the housing and is located below the fixed gripper 3, while the other end engages with an adjusting knob 4. One end of the adjusting knob 4 extends into the housing and is threaded into it, while the other end engages with one end of the movable gripper 1. When the adjusting knob 4 is turned downwards, one end of the movable gripper 1 is pressed down, causing the movable gripper 1 to rotate around the connecting pin. The other end of the movable gripper 1 engages with the fixed gripper 3 above it to clamp the gripper at the edge of the operating table. To release the gripper, the adjusting knob 4 is turned outwards, causing the gripper to open as the end of the spring 2 abuts against the fixed pin.

[0034] The joint axis 8 and the mounting part are used after being sterilized. The robotic arm 11 is sterilized and packaged and installed at the end of the joint axis 8. When in use, it is fixed to the side of the operating table by the cooperation of the fixed gripper 3 and the movable gripper 1 on the mounting part. Then, the position of the joint axis 8 is adjusted so that the robotic arm 11 is at a suitable height and angle. Pressing button 10 energizes the electromagnet 5, and the cylinders 81 on the joint axis 8 attract each other to maintain their position. At the same time, the axis is attracted and tightened, and the surgical instruments are installed on the robotic arm 11.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
