Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a multifunctional electronic positioning and fixing device applied to an arthroscopy. Background Art

[0002] Arthroscopy is a common method for the diagnosis and treatment of joint surgical diseases in clinical practice. In the process of using arthroscopy for surgery, the usual procedure is to first perform a preliminary positioning of the lesion through imaging or a more complete physical examination, and then try to insert a working channel. The working channel is the basis of all arthroscopic operations. In arthroscopic surgery, all operations in the joint cavity are performed by inserting various arthroscopic instruments into the joint cavity through the working channel, completing the operation in the joint cavity, and then completing the entire operation. The working channel is mainly composed of a hollow tubular structure. At the beginning of the operation, this device is first inserted directly into the joint cavity, and then the core is pulled out to provide a channel for various arthroscopic instruments to pass through. Therefore, the establishment of a working channel is the prerequisite for all arthroscopic surgeries.

[0003] Hip arthroscopy is used to perform bone grafting, osteotomy, and implantation of porous tantalum rods. These operations are difficult and traumatic, and take a long time. In addition, arthroscopy is performed manually, and human factors may cause deviations during the operation, affecting the quality and efficiency of the operation.

[0004] At present, relevant locator patents only focus on limb positioning issues, but not on the limitation of instruments. There is no strict positioning management for surgical instruments. During manual operation, factors such as emotional fluctuations and skills will also affect the accuracy of the operation, thereby reducing the efficiency of the operation, prolonging the operation time, increasing the radiation intake of patients and medical staff, and causing physical harm to related personnel. At the same time, the relative relationship between the lesion area and the anatomical position on the body surface is not shown, and the surgical space orientation cannot be accurately guided, which affects the accuracy of the operation of the surgeon.

[0005] In view of the above technical problems, it is necessary to improve the existing locator structure so that it can not only effectively and reliably fix the limbs, but also effectively limit the spatial positioning of the instruments, so that surgical operations can be performed without considering the spatial orientation problem. At the same time, it should have measurement and display functions to accurately measure the anatomical position of the lesion area and the body surface, thereby accurately determining the surgical field of view and providing support for drilling, bone grafting, suturing and resection of diseased tissue.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0036] In the above description of the present invention, it should be noted that the terms "one side", "the other side", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0037] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0038] like Figure 1-9 As shown, this embodiment provides a multifunctional electronic positioning and fixing device for arthroscopy, including a support 1, a limb fixing seat 2, an instrument fixing seat 3 and a measuring mechanism.

[0039] The support includes a fixed block 28 and a sliding block 29, which are slidably arranged above the fixed block. The fixed block and the sliding block are both U-shaped plates. The two U-shaped plates are opposite and arranged up and down to form an operating space between the two. There is a socket between the fixed block and the sliding block, and a latch 30 is arranged in the socket. Both sides of the U-shaped fixed block are provided with slide grooves 31 that slide with the sliding block. Before use, the sliding block can be moved to the far end by sliding in the slide groove, such as Fig.10 As shown, it is convenient to put the affected limb into the operating space. After the affected limb is put into the operating space, the moving block is moved back to its original position, and then the latch is put into the socket set in the fixed block and the sliding block to lock it, thereby completing the preparation operation.

[0040] The limb fixing seat is arranged on the concave side surface of the fixing block, specifically including a left baffle 4, a right baffle 5, a left baffle plate 6 and a right baffle plate 7. The left baffle plate and the right baffle plate are elastic plates arranged opposite to each other. The elastic plates are made of spring steel and have elastic restoring force. The elastic plates include a supporting plate 8 and an arc-shaped plate 9 arranged integrally with the supporting plate. The supporting plate is arranged in a vertical direction. The arc-shaped plate is connected to the supporting plate through a bending portion 10 to form an integral structure. The two elastic plates are arranged opposite to each other. The arc-shaped plate is arranged on the inner side of the supporting plate in a suspended state. A limb fixing position 11 is formed between the two arc-shaped plates. The left baffle plate is arranged on the left side of the left baffle plate, and the right baffle plate is arranged on the left side of the left baffle plate. The plate is arranged on the right side of the right baffle, and a support spring 12 is arranged between the left baffle and the left baffle, between the right baffle and the right baffle, and between the arc-shaped piece and the fixing block. The support spring forms elastic support for the arc-shaped piece and the support piece. When the affected limb enters from the opening of the U-shaped plate and is placed in the limb fixing position, when the patient's limb is placed, the arc-shaped piece is pressed downward to deform downward. At the same time, the support piece is pressed to both sides to expand to both sides. At this time, the support spring is deformed and has a certain elastic restoring force to resist this deformation and feedback to the limb, thereby forming a certain clamping force on the limb to form a fixation.

[0041] The instrument fixing seat includes a limiting sleeve 13 and a driving mechanism for driving the limiting sleeve to move, the driving mechanism includes a moving block 14, a left-right moving pole 15, a front-and-back moving pole 16 and a rotating motor 17, the moving block is slidably arranged on the top of the support, the fixed end of the left-right moving pole is fixed to the top of the support, the telescopic end of the left-right moving pole is fixed to the slider, the fixed end of the front-and-back moving pole is fixed to the slider, the telescopic end of the front-and-back moving pole is fixed to the rotating motor, the output spindle of the rotating motor is fixed to the limiting sleeve, a limiting hole for passing the instrument is provided through the limiting sleeve, the moving block is provided with a slider, the support is provided with a slider The sliding groove matches the block. When the left and right moving rod pushes, the moving block moves along the sliding groove to realize left and right movement. Since the front and back moving rods are fixed on the sliding block, the front and back moving rods are pushed to move left and right, and the extension and contraction of the front and back moving rods realizes the front and back movement. Since the rotating motor is fixed to the front and back moving rods, the rotating motor is pushed to move forward and backward. Furthermore, since the output spindle of the rotating motor is fixed to the limit sleeve, the limit sleeve has the freedom of rotation, front and back movement and left and right movement, so that its spatial direction can be effectively adjusted to achieve the purpose of adjusting the surgical instrument to correspond to the lesion area.

[0042] The measuring mechanism includes a controller, a display screen 19, an electronic rangefinder 20 arranged on the inner side of the moving block, an angle gauge 21 arranged on the top of the moving block and a scale pointer 22 arranged on the limit sleeve. The controller is electrically connected with the display screen, the electronic rangefinder, the left and right moving pole, the front and back moving pole and the rotating motor. The controller is used to adjust the electronic rangefinder to perform distance measurement operations. At the same time, it can also control the driving mechanism to adjust the spatial orientation of the limit sleeve to adapt to the lesion orientation, so as to perform drilling, bone grafting and other operations. The display screen is fixed on the support through the bracket 18, and can display the operation status and the measurement results. The controller is arranged in the bracket, and the electronic rangefinder is electrically connected to ... The rangefinder is used to measure the depth of the operating hole to determine the required length of the operating device. In order to achieve the position adjustment of the electronic rangefinder, the present embodiment is provided with a moving mechanism, which can push the electronic rangefinder to move near the operating hole so as to align with the operating hole, make the two coaxial or approximately coaxial, and make the measurement more accurate. The angle meter of the present embodiment includes an arc plate, and an angle scale line 23 for the scale pointer to point to is provided on the arc plate. When the rotating motor drives the limit sleeve to rotate, it drives the scale pointer to rotate, and reads the specific angle through the angle scale line. The angle center of the angle scale line coincides with the rotation center of the rotating motor, which also makes the rotation angle consistent with the measured angle, which is convenient for real-time and precise control.

[0043] When this embodiment is used, the moving block is first slid out, and then the affected limb is placed in the limb fixing seat for fixing. After fixing, the moving block is moved back and fixed with a latch, and then the spatial orientation of the limiting sleeve is adjusted so that the lesion area can be drilled. Then the drilling operation is performed, and then the distance between the lesion and the external operation site or the depth of the drilling is measured to select an instrument of appropriate length, and further operations such as establishing a working channel, bone grafting, and implanting porous tantalum rods are performed.

[0044] By fixing the joints and accurately measuring the anatomical position of the lesion area and the body surface, as well as properly selecting and reliably fixing the instruments, the accuracy and reliability of the surgery can be effectively improved, which is beneficial to improving surgical efficiency, shortening operation time, and reducing patient pain.

[0045] In this embodiment, a depth measuring rod 24 is also included, on which a depth scale 27 is provided, and the outer diameter of the depth measuring rod matches the inner diameter of the limit sleeve. By passing the depth measuring rod through the limit sleeve, the depth of the drill hole can be directly measured, thereby providing a method for manually measuring the distance from the outside to the lesion as a supplement to electronic measurement.

[0046] In this embodiment, an introduction cone 25 is provided at the inlet of the limiting sleeve to guide the operating instrument, facilitate rapid introduction, and improve operating efficiency.

[0047] In this embodiment, a clip 26 is provided in the inner hole of the limiting sleeve, and the clip can have a certain restraining effect on the instrument, thereby preventing the operating instrument from shaking and further improving the accuracy of the operation.

[0048] In particular, the right baffle of the present embodiment is configured as an L-shaped plate, the L-shaped opening of the L-shaped plate is configured inwardly, and a sliding groove 32 that slides with the L-shaped plate is provided on the inner side of the fixed seat, so that the distance between the right baffle and the left baffle can be adjusted to achieve a variety of widths, thereby adapting to different joints or different patients. To facilitate adjustment, the present embodiment is also provided with a driving push rod 33, the fixed end of the driving push rod is fixed to the fixed seat, and the telescopic end of the driving push rod is fixed to the right stopper, thereby realizing electric drive, which does not require manual operation and is more labor-saving.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
