Description

Technical Field

[0001] The present invention relates to the field of surgical instrument fixation, and in particular to a surgical instrument fixation auxiliary device. Background Art

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

[0003] There are specialized fixtures designed to hold and support surgical instruments. However, most of these fixtures on the market are one-piece designs, requiring reusable, cleansing and disinfection before and after each use. This not only increases the workload for disinfection personnel, but incomplete disinfection can also carry bacteria during the next use, potentially causing infection during surgery.

[0004] Traditional surgical clamping and fixation devices have the following technical defects: 1. The fully mechanical locking structure makes the surgical instrument posture unstable, and the instrument will wear out after long-term use, which may cause micro-movement of the instrument, affecting the surgical operation and increasing the risk of surgery.

[0005] 2. Traditional surgical clamping and fixation devices can only clamp customized special surgical instruments and are not compatible with conventional surgical instruments or surgical endoscopes, making their use scenarios limited.

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

[0007] 4. The clamping part and the mounting part of the traditional surgical clamping and fixing device are connected as one piece and need to be repeatedly disinfected. If the disinfection is not thorough, bacteria will be present and there is a risk of infection. Summary of the Invention

[0008] The purpose of the present invention is to provide a surgical instrument fixing auxiliary device, in which the cylinders are attracted to each other to maintain their positions after the electromagnet is energized, making adjustment convenient.

[0009] In order to solve the above technical problems, the following technical solutions are adopted: The present invention provides a surgical instrument fixing auxiliary device, comprising a clamping portion, a joint shaft, and a mounting portion. One end of the joint shaft is connected to the mounting portion, and the mounting portion is used to install the entire auxiliary device beside an operating table. The clamping portion is used to clamp the surgical instrument and is a disposable consumable. The joint shaft includes several cylinders with saddle surfaces on both upper and lower end surfaces. The upper and lower end surfaces of the several cylinders are matched and connected in series through 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. The electromagnet is used to conduct magnetism to the cylinder when energized, so that the several cylinders are adsorbed together to maintain their position.

[0010] Optionally, the joint shaft also includes two end cylinders, only one end face of which is provided with a saddle surface. The end face of one end cylinder without a saddle surface is connected to the mounting portion, and the end face of the other end cylinder without a saddle surface is connected to the clamping portion. The end faces of the two end cylinders with a saddle surface are both cooperatively connected to the cylinder.

[0011] Optionally, a sector-shaped chuck is provided on the end cylinder connected to the mounting portion, and a slot cooperating with the sector-shaped chuck is provided on the mounting portion.

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

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

[0014] Optionally, the power supply battery is connected to the electromagnet through a power control board to control the opening and closing of the electromagnet. When turned on, the electromagnet adsorbs the axis in the joint shaft, thereby pulling the mechanical claw of the clamping part, thereby completing the closing of the mechanical claw. When closed, the axis is relaxed, thereby releasing the mechanical claw. The working state of the electromagnet is controlled by a button set on one end of the joint shaft close to the clamping part.

[0015] Optionally, the mounting portion includes a shell, a fixed jaw, a movable jaw and an adjusting knob, the fixed jaw is arranged on the shell, the movable jaw is movably connected to the inside of the shell through a spring and a connecting pin, one end of the movable jaw extends from the inside of the shell and cooperates with the fixed jaw to form a jaw, and the adjusting knob is used to adjust the opening and closing of the jaw.

[0016] Optionally, the clamping portion includes a manipulator for clamping surgical instruments.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention adjusts the position of the clamping part through the joint axis. The joint axis maintains the position after the electromagnet is energized, and adjusts the position of the joint axis after the electromagnet is de-energized. The state of the end clamping part can be accurately adjusted during use, which is convenient to use. The opening and closing of the clamping part is controlled by the axis to adapt to clamping surgical instruments of different sizes.

[0018] 2. The joint shaft and axis of the present invention are both composed of a cylinder made of Permalloy, and the ends of the cylinder are connected with each other using saddle surfaces, which makes the adjustment of the joint shaft smoother. After the electromagnet is energized, the position can be stably maintained due to the easy magnetic conductivity of Permalloy. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] This embodiment provides a surgical instrument fixing auxiliary device, comprising a clamping portion 9, a joint shaft 8, and a mounting portion. The clamping portion 9 is connected to the mounting portion via the joint shaft 8. The mounting portion is used to install the entire auxiliary device in a use position. The clamping portion 9 is used to clamp the surgical instrument 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 upper and lower end surfaces. The upper and lower end surfaces of several of the cylinders 81 are matched and connected in series through 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 cylinder 81 when energized, so that several cylinders 81 are adsorbed together to maintain their position.

[0024] When in use, the entire auxiliary device is installed on the side of the operating table through the installation part, and the instruments used in the operation are clamped by the clamping part 9. After the electromagnet 5 is powered off, the joint axis 8 is adjusted so that the surgical instruments maintain a certain height and angle. After the adjustment is completed, the electromagnet 5 is powered on, so that the several cylinders 81 have magnetism and are attracted to each other to maintain their position.

[0025] The clamping part 9 is a disposable consumable, and the joint shaft 8 and the mounting part can be used multiple times. The clamping part 9 needs to directly contact the surgical instrument. Setting the clamping part 9 as a disposable consumable can prevent contamination of the surgical instrument and is safer.

[0026] An axis is provided inside the joint shaft 8, and the axis is also connected to the clamping part 9 to drive the opening and closing of the clamping part 9. The axis connects the joint shaft 8 in series into a whole. After the adjustment is completed, the electromagnet 5 is energized to maintain the position of the joint shaft 8. At the same time, the joint shaft 8 absorbs the axis and closes the clamping part at the end, thereby clamping the surgical instrument. Example 2

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

[0028] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 As shown, the joint shaft 8 is composed of a number of cylinders 81 with saddle surfaces 811 at both ends and two end cylinders 81 with a saddle surface 811 on only one end face. The end of one end cylinder 81 without a saddle surface 811 is connected to the mounting portion, and the end of the other end cylinder 81 without a saddle surface 811 is connected to the clamping portion 9. The ends of the two end cylinders 81 with saddle surfaces 811 cooperate with the saddle surfaces 811 on the other cylinders 81 respectively. The saddle surfaces 811 on the upper and lower end faces of the cylinder 81 are arranged at ninety degrees, and the two adjacent saddle surfaces 811 that cooperate with each other are staggered and connected at ninety degrees. The cylinders 81 can be increased or decreased according to the needs during surgery for easy use.

[0029] like Figure 8 As shown, a fan-shaped chuck 82 is provided on the end cylinder 81 connected to the mounting portion, and two fan-shaped chucks 82 are symmetrically arranged on the side wall of the lower end of the end cylinder 81. A slot that cooperates with the fan-shaped chuck 82 is provided on the mounting portion. The end cylinder 81 is installed on the mounting portion through the cooperation between the fan-shaped chuck 82 and the slot.

[0030] like Figure 3 、 Figure 5As shown, a power supply battery 7 is also provided in the mounting portion. The power supply battery 7 is connected to the electromagnet 5 through a power control board 6. The working state of the electromagnet 5 is controlled by a button. The button 10 is provided on one end of the joint shaft 8 near the clamping portion 9. After the joint shaft 8 is conveniently adjusted, the button 10 is pressed and the electromagnet 5 is energized. The electromagnet 5 generates a magnetic field after being energized. The magnetic field is transmitted to the cylinder 81. Several cylinders 81 have magnetism and are attracted to each other to maintain their posture. The cylinder 81 is made of permalloy, which has the characteristic of easy magnetic conductivity. The magnetic field generated by the electromagnet 5 makes the cylinder 81 magnetic and then attracts each other. When the battery does not supply power to the electromagnet 5, the electromagnet 5 does not generate a magnetic field. The cylinder 81 is only connected in series by the axis of the middle part. The posture of several cylinders 81 can be adjusted. Then the electromagnet 5 is turned on to maintain the adjusted posture, which is convenient for the use of the end clamping portion 9.

[0031] The axis connected to the clamping portion 9 is also made of permalloy. When the electromagnet 5 is energized, the cylinders 81 are attracted together, and at the same time, the axis is attracted, causing the axis to be pulled toward the mounting portion, thereby closing the clamping portion 9 and clamping the surgical instrument. When the electromagnet 5 is de-energized, the axis is released and the clamping portion 9 opens.

[0032] like Figure 3 As shown, the clamping portion 9 includes a manipulator 11, which is mounted on the end cylinder 81 and connected to the axis. The manipulator 11 is opened and closed by the control of the axis and the electromagnet 5. Among them, the model of the manipulator 11 in this embodiment can be Epson VT6L.

[0033] like Figure 5 、 Figure 6 As shown, the mounting portion includes a shell, a fixed jaw 3 and a movable jaw 1. The fixed jaw 3 is arranged on the outside of the shell, and the movable jaw 1 is installed on the inside of the shell through a connecting pin and a spring 2. The spring 2 is arranged on the connecting pin, and one end is against the fixed pin next to the movable jaw 1. One end of the movable jaw 1 extends from the inside of the shell and is located below the fixed jaw 3, and the other end is in contact with the adjusting knob 4. One end of the adjusting knob 4 extends into the shell and is threadedly connected to the shell, and the end is in contact with one end of the movable jaw 1. When the adjusting knob 4 is turned downward, one end of the movable jaw 1 is pressed down, so that the movable jaw 1 rotates around the connecting pin, and the other end of the movable jaw 1 cooperates with the fixed jaw 3 above it to clamp it at the side of the operating bed for use. When it needs to be loosened, the adjusting knob 4 is turned outward, and the jaw opens because the end of the spring 2 is against the fixed pin.

[0034] The joint shaft 8 and the mounting part are disinfected and sterilized before use. The manipulator 11 is sterilized and packaged and installed at the end of the joint shaft 8. When in use, it is fixed to the edge of the operating table through the fixed clamp 3 and the movable clamp 1 on the mounting part, and then the posture of the joint shaft 8 is adjusted so that the manipulator 11 is at the appropriate height and angle. Press the button 10, the electromagnet 5 is energized, and the cylinders 81 on the joint shaft 8 are adsorbed against each other to maintain the posture. At the same time, the axis is adsorbed and tightened, and the surgical instrument is installed on the manipulator 11.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
